Section  305(b) of the Clean Water Act:
This report was prepared pursuant to Section 305(b) of the Clean Water Act, which states:

   (b)(1) Each State shall prepare and submit to the Administrator by April 1,1975,
         and shall bring up to date by April 1,1976, and biennially thereafter, a
         report which shall include—
         (A) a description of the water quality of all navigable waters in such State
            during the preceding year, with appropriate supplemental descriptions
            as shall be required to take into account seasonal, tidal, and other varia-
            tions, correlated with the quality of water required by the objective of
            this Act (as identified by the Administrator pursuant to criteria published
            under section 304(a) of this Act) and the water quality described in
            subparagfaph (B) of this paragraph;
         (B) an analysis of the extent to which all navigable waters of such State
            provide for the protection and propagation of a balanced population
            of shellfish, fish, and wildlife, and allow recreational activities in and on
            the water;
         (C) an analysis of the extent to which the elimination of the discharge of
            pollutants and a level of water quality which provides for the protection
            and propagation of a balanced population of shellfish, fish, and wildlife
            and allows recreational activities in and on the water, have been or will
            be achieved by the requirements of this Act, together with recommenda-
            tions as to additional action necessary to achieve such objectives and for
            what waters such additional action is necessary;
         (D) an estimate of (i) the environmental impact, (ii) the economic and social
            costs necessary to achieve the objective of this Act in such State, (iii) the
            economic and social benefits  of such  achievement; and (iv) an estimate
            of the date of such achievement; and
         (E) a description of the nature and extent of nonpoint sources of pollutants,
            and recommendations as to the programs which must be undertaken to
            control each category of such sources, including an estimate of the costs
            of implementing such programs.
     (2) The Administrator shall transmit such State reports, together with an analysis
         thereof, to Congress on or before October 1,1975, and October 1,1976,
         and biennially thereafter.

                                                                                        THE ADMINISTRATOR
 The Honorable Albert Gore
 President of the Senate
 Washington, D.C.  20510

 Dear Mr. President:

    As required by Section 305(b) of the Clean Water Act (CWA), I am transmitting to the Congress the 1994
 National Water Quality Inventory Report. This biennial report is the tenth in a series of national water quality
 assessments published since 1975 by the U.S. Environmental Protection Agency. On December 14,1995, we
 transmitted to you the executive summary of the report and summaries of water quality conditions in each of the
 States and Territories; the enclosed includes the entirety of the report.

    Based on surveys conducted by the States, this report indicates that, while most of the Nation's surveyed
 waters are of good quality, about 40 percent of the Nation's surveyed rivers, lakes, and estuaries are too polluted
 for basic uses, such  as fishing or swimming. These results are consistent with those reported in 1992 and show
 that, on the whole,  we have managed to hold the line or prevent further degradation, and stifl maintain continued
 population growth and growth in economic activity.

    States reported  that the beneficial uses that they designate for the waters in their water quality standards, such
 as drinking water supply, swimming, and the propagation of aquatic life, were impaired in 36 percent of surveyed
 river miles, 37 percent of surveyed lake acres, and 36  percent of surveyed estuarine square miles. In addition, States
 report that they consider some of the good quality waters threatened because they could become impaired if
 pollution prevention or control actions are not taken.

    According to the States, the most commonly reported problem in impaired waters is polluted runoff from
 agricultural lands and urban streets. Pollutants include nutrients, siltation, and bacteria. Agriculture is the leading
 source of pollution in rivers and lakes, and ranks in the top three sources in estuaries.

    It is important to recognize that, despite the remarkable accomplishments of the past two decades, significant
 water pollution  problems remain. The cost of sewage  treatment still needed is estimated to be over $100 billion.
 Toxic pollutants discharged by industry continue to pose a threat to humans, aquatic life,  and wildlife. Runoff from
 agricultural operations, city streets, and construction sites also causes significant water pollution problems.
 Wetlands, which cleanse our waters, protect our properly from floods, and provide breeding grounds for our
 Nation's fisheries and waterfowl, continue to be lost and degraded. For these reasons, we want to ensure that we
 continue the progress we have made toward cleaner water and address our remaining water pollution problems.
 We look forward to working with Congress in efforts leading toward this goal.

 Sincerely,
Carol M. Browner

The Quality of  Our  Nation's  Water
         Introduction

             The National Water Quality
         Inventory Report to Congress is the
         primaiy vehicle for informing Con-
         gress and the public about general
         water quality conditions in the
         United States. This document char-
         acterizes our water quality, identifies
         widespread water quality problems
         of national significance, and
         describes various programs imple-
         mented to restore and protect our
         waters.
             The National Water Quality
         Inventory Report to Congress summa-
         rizes the water quality information
         submitted by 61  States, American
         Indian Tribes, Territories, Interstate
         Water Commissions, and the District
         of Columbia (hereafter referred to
         as States, Tribes, and other jurisdic-
         tions) in their 1994 water quality
         assessment reports.  As such, the
         report identifies water quality issues
         of concern to the States, Tribes, and
         other jurisdictions, not just the
         issues of concern to the U.S. Envi-
         ronmental Protection Agency (EPA).
         Section 305(b) of the Clean Water
         Act (CWA) requires that the States
         and other participating jurisdictions
         submit water quality assessment
         reports every 2 years. Most of the
         survey information in the 1994
         Section 305(b) reports is based on
         water quality information collected
         and evaluated by the States, Tribes,
         and other jurisdictions during 1992
         and 1993.
             It is  important to note that this
         report is based on information sub-
         mitted by States, Tribes, and other
         jurisdictions that do not use identi-
         cal survey methods and criteria to
         rate their water quality. The States,
                                   Tribes, and other jurisdictions favor
                                   flexibility in the 305(b) process to
                                   accommodate natural variability in
                                   their waters, but there is a trade-off
                                   between flexibility and consistency.
                                   Without known and consistent sur-
                                   vey methods in place, EPA must use
                                   caution in  comparing data or deter-
                                   mining the accuracy  of data submit-
                                   ted by different States and jurisdic-
                                   tions. Also, EPA must use caution
                                   when comparing water quality
                                   information submitted during differ-
                                   ent 305(b) reporting  periods
                                   because States and other jurisdic-
                                   tions may  modify their criteria or
                                   survey different waterbodies every
                                   2 years.
                                       For over 10 years, EPA has pur-
                                   sued a balance between flexibility
                                   and consistency in the Section
                                   305(b) process. Recent actions by
                                   EPA, the States, Tribes, and other
                                   jurisdictions include implementing
                                   the recommendations of the
                                   National 305(b) Consistency
Workgroup and the Intergovern-
mental Task Force on Monitoring
Water Quality. These actions will
enable States and other jurisdictions
to share data across political bound-
aries as they develop watershed
protection strategies.
    EPA recognizes that national
initiatives alone cannot clean up our
waters; water quality protection and
restoration must happen at the local
watershed level, in conjunction with
State, Tribal, and  Federal activities.
Similarly, this document alone can-
not provide the detailed information
needed to manage water quality at
all levels. This document should be
used together with the individual
Section 305(b)  reports (see the
inside back cover for information on
obtaining the State and Tribal  Sec-
tion 305(b) reports), watershed
management plans, and other local
documents to develop integrated
water quality management options.

 Key  Concepts
Measuring Water
Quality

    The States, participating Tribes,
and other jurisdictions survey the
quality of their waters by determin-
ing if their waters attain the water
quality standards they established.
Water quality standards consist of
beneficial uses, numeric and narra-
tive criteria for supporting each use,
and an antidegradation statement:

•  Designated beneficial uses are
the desirable uses that water quality
should support. Examples are drink-
ing water supply, primary contact
recreation (such as  swimming), and
aquatic life support. Each desig-
nated use has a unique set of water
quality requirements or criteria that
must be met for the use to be real-
ized. States, Tribes, and other juris-
dictions may  designate an individual
waterbody for multiple beneficial
uses.

•  Numeric water quality criteria
establish the minimum physical,
chemical, and biological parameters
required to support a beneficial use.
Physical and chemical numeric
criteria may set maximum concen-
trations of pollutants, acceptable
ranges of physical parameters, and
minimum concentrations of desir-
able parameters, such as dissolved
oxygen. Numeric biological criteria
describe the expected attainable
community attributes and establish
values based  on measures such as
species richness, presence or
absence of indicator taxa, and
distribution of classes of organisms.
•  Narrative water quality criteria
define, rather than quantify, condi-
tions and attainable goals that must
be maintained to support a desig-
nated use. Narrative biological cri-
teria establish a positive statement
about aquatic community character-
istics expected to occur within a
waterbody. For example, "Ambient
water quality shall be sufficient to
support life stages of all native
aquatic species." Narrative criteria
may also describe conditions that
are desired in a waterbody, such as
"Waters must be free of substances
that are toxic to humans, aquatic
life, and wildlife."

•  Antidegradation statements,
where possible, protect existing uses
and prevent waterbodies from dete-
riorating, even if their water quality
is better than the fishable and swim-
mable water quality goals of the
Act.

    The CWA allows States, Tribes,
and other jurisdictions to set their
own standards but requires that all
beneficial uses and their criteria
comply with the goals of the Act. At
a minimum, beneficial uses must
provide for "the protection and
propagation of fish, shellfish,  and
wildlife" and provide for "recreation
in and on the water" (i.e., the fish-
able and swimmable goals of the
Act), where attainable. The Act pro-
hibits States and other jurisdictions
from designating waste transport or
waste assimilation as a beneficial
use, as some States did prior to
1972.
    Section 305(b) of the CWA
requires that the States biennially
survey their water quality for attain-
ment of the fishable and swimmable
goals of the Act and report the re-
sults to EPA. The States, participat-
ing Tribes, and other jurisdictions
measure attainment of the CWA
goals by determining how well their
waters support their designated
beneficial uses. EPA encourages the
surveying of waterbodies for  sup-
port of the following individual
beneficial uses:

              Aquatic
              Life Support

              The waterbody pro-
vides suitable habitat for protection
and propagation of desirable fish,
shellfish, and other aquatic organ-
isms.
                                                                                                         ES-3.

-------
                Fish Consumption

                The waterbody sup-
                ports fish free from
   contamination that could pose a
   human health risk to consumers.
                Shellfish Harvesting

                The waterbody sup-
                ports a population
   of shellfish free from toxicants and
   pathogens that could pose a human
   health risk to consumers.
                Drinking Water
                Supply
                The waterbody can
   supply safe drinking water with
   conventional treatment.
                Primary Contact
                Recreation -
                Swimming

   People can swim in the waterbody
   without risk of adverse human
   health effects (such as catching
   waterborne diseases from raw
   sewage contamination).

                Secondary Contact
                Recreation
                People can perform
  activities on the water (such as
  boating) without risk of adverse
  human health effects from ingestion
  or contact with the water.
                The water quality is
                suitable for irrigating
  fields or watering livestock.

      States, Tribes, and other juris-
  dictions may also define their own
  individual uses to address special
concerns. For example, many Tribes
and States designate their waters for
the following beneficial uses:

             Ground Water
             Recharge

             The surface
waterbody plays a significant role in
replenishing ground water, and
surface water supply and quality
are adequate to protect existing or
potential uses of ground water.
             Wildlife Habitat

             Water quality sup-
             ports the waterbody's
role in providing habitat and
resources for land-based wildlife as
well as aquatic life.

   Tribes may designate their
waters for special cultural and
ceremonial uses:
                   Water Quality Monitoring
       Water quality monitoring consists of data collection and sample
   analysis performed using accepted protocols and quality control proce-
   dures.  Monitoring also includes subsequent analysis of the body of
   data to support decisionmaking. Federal, Interstate, State, Territorial,
   Tribal,  Regional, and local agencies, industry, and volunteer groups
   with approved quality assurance programs monitor a combination of-
  . chemical, physical, and biological water quality parameters throughout
   the country.                                             ^  ;;    :
   •  Chemical data often  measure concentrations of pollutants and other
      chemical conditions that influence aquatic life, such as pH (i.e., acid-;
      ity) and dissolved oxygen  concentrations. The chemical data may  be
      analyzed in water samples, fish tissue samples, or sediment samples.
   •  Physical data include measurements of temperature, turbidity      :
      (i.e., light penetration through the water column), and solids in
      the water column.                                 ,
  ^•; JSiplpgical data measure the health of aquatic communities.
      Biological data include counts of aquatic species that indicate
      healthy ecological conditions.
   •  Habitat and ancillary data  (such as land use data) help interpret the
      above monitoring information.
       Monitoring agencies vary parameters, sampling frequency, and
   sampling site selection, to meet program objectives and funding con-
  ;:Straints, Sampling may occur at regular intervals (such as monthly,
   quarterly, or annually), irregular intervals, or during one-time intensive
   surveys. Sampling may be conducted at fixed sampling stations/ran-
   domly selected stations, stations near suspected water quality prob-
   lems, or stations in  pristine waters.                      ;'•'•••

-------
             Culture

             Water quality sup-
             ports the waterbody's
role in Tribal culture and preserves
the waterbody's religious, ceremo-
nial, or subsistence significance.

   The States,  Tribes, and:other
jurisdictions assign one of five levels
of use support categories to each of
their waterbodies (Table ES-1). If
possible, the States, Tribes, and
other jurisdictions determine the
level of use support by comparing
monitoring data with numeric crite-
ria for each use designated for a
particular waterbody. If monitoring
data are not available, the State,
Tribe, or other jurisdiction may de-
termine the level  of use support
with qualitative information. Valid
qualitative  information  includes land
use data, fish and game surveys,
and predictive model results.  Moni-
tored assessments are based on
monitoring data.  Evaluated assess-
ments are based  on qualitative in-
formation or monitored information
more than 5  years old.

    For waterbodies with more than
one designated use, the States,
Tribes, and other jurisdictions con-
solidate the individual use support
information into a single overall use
support determination:
          Good/Fully Supporting
          Overall Use - All desig-
          nated beneficial uses are
          fully supported.!

          Good/Threatened Over-
          all Use - One or more
          designated beneficial uses
          are threatened and the
 remaining uses are fully supported.
         Fair/Partially Supporting
         Overall Use - One or
         more designated bene-
         ficial uses are partially
supported and the remaining uses
are fully supported or threatened.
These waterbodies are considered
impaired.

         Poor/Not Supporting
         Overall Use - One or
         more designated benefi-
         cial uses are not
supported. These waterbodies are
considered impaired.
         Poor/Not Attainable —
         The State, Tribe, or other
         jurisdiction has performed
         a use-attainability analysis
and demonstrated that use support
of one or more designated benefi-
cial uses is not attainable due to
one of six biological, chemical,
physical,  or economic/social condi-
tions specified in the Code of Federal
Regulations (40 CFR Section
131.10).  These conditions include
naturally high concentrations  of
pollutants (such as metals); other
natural physical features that create

   jurisdictions into a national assess-
   ment of the Nation's water quality.

   How Many of Our
   Waters Were
   Surveyed for 1994?

      National estimates of the total
   waters of our country provide the
   foundation for determining the per-
   centage of waters surveyed by the
   States, Tribes, and other jurisdictions
   and the portion impaired  by pollu-
   tion.  For the 1992 reporting period,
   EPA provided the States with esti-
   mates of total river miles and lake
   acres derived from the EPA Reach
   File, a database containing traces of
   waterbodies adapted from
   1:100,000 scale maps prepared by
   the U.S. Geological Survey. The
States modified these total water
estimates where necessary. Based on
the 1992 EPA/State figures, the
national estimate of total river miles
doubled in large part because the
EPA/State estimates included
nonperennial streams, canals, and
               ditches that were previously
               excluded from estimates of total
               stream miles.
                   Estimates for the 1994 reportipg
               cycle are a minor refinement of the
               1992 figures and indicate that the
               United States has:

            The Intergovernmental Task Force
                on Monitoring Water Quality

 t.*v" In 1992, the Intergovernmental Task Force on Monitoring Water,
 \  Quality (ITFM) convened to prepare a strategy for improving water
 l^quality monitoring nationwide. The ITFM is a Federal/State partnership
 £' of 10 Federal agencies, 9 State andf Interstate agencies, and 1 Ameri-
 • "can Indian Tribe. The EPA chairs the ITFM with the USGS as vice chair
 /  and Executive Secretariat as part of their Water Information Coordina-
ff^tion Program pursuant to OMB memo 92-01.

 ?> •  ,The mission of the ITFM is to develop and aid implementation of a
 3 national strategic plan to achieve effective collection, interpretation,
 •  and presentation of water quality data  and to improve the  availability
 , of existing information for decisionmaking at all levels of government
 •; and the private sector. A permanent successor to the ITFM, the
 ,  National Monitoring Council will provide guidelines and support for
   institutional  collaboration, comparable field  and laboratory methods,
 ',', quality assurance/quality control, environmental indicators,  data man-
 f. agement and sharing, ancillary data, interpretation and techniques,
   and training.

      The ITFM and its successor, the National Monitoring Council, are
   also producing  products that can be used by monitoring programs
   nationwide,  such as an outline for a recommended monitoring pro-
 -  gram, environmental indicator selection criteria, and a matrix of indica-
   tors to support assessment of  State and Tribal designated uses.

    Most States do not survey all of
their waterbodies during the 2-year
reporting cycle required under CWA
Section 305(b). Thus, the surveyed
waters reported in Figure ES-1  are a
subset of the Nation's total waters.
In addition, the summary informa-
tion based on surveyed waters may
not represent general conditions in
the Nation's total waters because
States, Tribes, and other jurisdictions
often focus on surveying major
perennial rivers, estuaries, and  pub-
lic lakes with suspected pollution
problems in order to direct scarce
resources to areas that could pose
the greatest risk. Many States,
Tribes, and other jurisdictions lack
the resources to collect use support
information for nonperennial
streams, small tributaries, and
private ponds. This report does not
predict the health of these
unassessed waters, which include an
unknown ratio of pristine waters to
polluted waters.


Pollutants and
Processes That
Degrade Water
Quality

    Where possible, States,  Tribes,
and other jurisdictions identify the
pollutants or processes that degrade
water quality and indicators that
document impacts of water quality
degradation. The most widespread
pollutants and processes  identified
in rivers, lakes, and estuaries are
presented in Table ES-2.  Pollutants
include sediment, nutrients, and
chemical  contaminants (such as
dioxins and metals). Processes that
                                                                                                        ES-7

-------
  degrade waters include habitat
  modification (such as destruction of
  streamside vegetation) and
  hydrologic modification (such as
  flow reduction). Indicators of water
  quality degradation include  physical,
  chemical, and biological parameters.
  Examples of biological parameters
  include species diversity and abun-
  dance. Examples of physical and
  chemical parameters include pH,
  turbidity, and temperature.  Follow-
  ing are descriptions of the effects of
  the pollutants and processes most
  commonly identified in rivers, lakes,
  estuaries, coastal waters, wetlands,
  and ground water.

  Low Dissolved Oxygen

      Dissolved oxygen is a basic
  requirement for a healthy aquatic
  ecosystem.  Most fish and beneficial
  aquatic insects "breathe" oxygen
  dissolved in the water column.
  Some fish and aquatic organisms
  (such as carp and sludge worms)
  are adapted to low oxygen  condi-
  tions, but most desirable fish species
  (such as trout and salmon) suffer if
  dissolved oxygen concentrations fall
  below 3 to  4 mg/L (3 to 4 milli-
  grams of oxygen dissolved in  1 liter
  of water, or 3 to 4 parts of oxygen
  per million  parts of water). Larvae
  and juvenile fish are more sensitive
  and require even higher concentra-
  tions of dissolved oxygen.
      Many fish and other aquatic
  organisms can recover from short
  periods of low dissolved oxygen
  availability.  However, prolonged
  episodes of depressed dissolved
  oxygen concentrations of 2 mg/L
  or less can result in "dead"water-
  bodies. Prolonged exposure to low
  dissolved oxygen conditions can
suffocate adult fish or reduce their
reproductive survival by suffocating
sensitive eggs and larvae or can
starve fish by killing aquatic insect
larvae and other prey. Low dissolved
oxygen concentrations also favor
anaerobic bacterial activity that pro-
duces noxious gases or foul odors
often associated with polluted
waterbodies.

       Fish kill reporting is a voluntary process; States, Tribes, and other
   jurisdictions are not required to report on how many fish kills occur, or
   what might have caused them. In many cases it is the, public-anglers,/
   and hunters, recreational boaters, or hi
   and report them to game wardens or other State officials. Many fish
   kills go undetected or unreported, and others may be difficult to inves-
   tigate, especially if they occur in remote areas. This is because dead
   fishmay be carriedquickly'downstreamfor' may be difficult to count
   because of turbid conditions,,. It is therefore Jkelythat the statistics pre-
   sented by the States, Tribes, and other jurisdictions underestimate the
   total number of fish kills that occurred nationwide Between 1992 and
  '1994. ,„'.,;.';'	"       '                           *T
       Despite these problems, fish kills are an important consideration in
   water quality assessments. In 1994, 32 States, Tribes, and other juris-
   dictions reported a total of  1,454 fish kill incidents. These States attrib-
   uted 737 of the fish kjlls to pollution, 257 to unknown causes/263 to
   natural conditions (such as:  low flpwjrid,.hjgh temperatures),, and 229
   kills to ambiguous causes. Ppllutap|s most often_ cited as the cause of
   kills include oxygen-depleting substances, sewage, pesticides, manure
  _and silage, oil and gas, chlorine, and ammonia. Leading sources of fish
   kills include agricultural activities, industrial discharges/municipal sew-
   age treatment plant discharges, spills, runoff, and pesticide
   applications.

-------
    Oxygen concentrations in the
water column fluctuate under natu-
ral conditions, but severe oxygen
depletion usually results from
human activities that introduce
large quantities of biodegradable
organic materials  into surface
waters. Biodegradable organic
materials contain  plant, fish, or ani-
mal matter. Leaves,  lawn clippings,
sewage, manure,  shellfish processing
waste, milk solids, and other food
processing  wastes are examples of
oxygen-depleting organic materials
that enter our surface waters.
    In both pristine  and polluted
waters, beneficial  bacteria use oxy-
gen to break apart (or decompose)
organic materials. Pollution-
containing  organic wastes provide a
continuous glut of food for the bac-
teria,  which accelerates bacterial
activity and population growth. In
polluted waters, bacterial consump-
tion of oxygen  can  rapidly outpace
oxygen replenishment from the
atmosphere and photosynthesis
performed  by algae and aquatic
plants. The result is  a net decline in
oxygen concentrations in the  water.
    Toxic pollutants can indirectly
lower oxygen concentrations  by
killing algae, aquatic weeds, or fish,
which provides an abundance of
food for oxygen-consuming bacte-
ria. Oxygen depletion can also result
from  chemical reactions that do not
involve bacteria. Some pollutants
trigger chemical reactions that place
a chemical oxygen demand on
receiving waters.
    Other factors (such as temper-
ature and salinity) influence the
amount of oxygen dissolved in
water. Prolonged hot weather will
depress oxygen concentrations and
may cause fish  kills  even  in clean
waters because warm water cannot
hold as much oxygen as cold water.
Warm conditions further aggravate
oxygen depletion by stimulating
bacterial activity and respiration in
fish, which consumes oxygen.
Removal of streamside vegetation
eliminates shade, thereby raising
water temperatures, and accelerates
runoff of organic debris. Under such
conditions, minor additions of pollu-
tion-containing organic materials
can severely deplete oxygen.

Nutrients
    Nutrients are essential building
blocks for healthy aquatic communi-
ties, but excess nutrients (especially
nitrogen and phosphorus com-
pounds) overstimulate the growth
of aquatic weeds and algae. Exces-
sive growth of these organisms, in
turn, can clog navigable waters,
interfere with swimming and boat-
ing, outcompete native submerged
aquatic vegetation (SAV), and lead
to oxygen depletion. Oxygen con-
centrations can fluctuate daily
during algal blooms, rising during
the day as algae perform photosyn-
thesis, and falling at night as algae
continue to respire, which consumes
oxygen. Beneficial bacteria also con-
sume oxygen as they decompose
the abundant organic food supply
in dying algae cells.
    Lawn and crop fertilizers, sew-
age, manure, and detergents con-
tain nitrogen and phosphorus, the
nutrients most often  responsible for
water quality degradation. Rural
areas are vulnerable to ground
water contamination from nitrates
(a compound containing nitrogen)
found in fertilizer and manure. Very
high concentrations of nitrate
(>10 mg/L) in drinking water cause
methemoglobinemia, or blue baby
syndrome, an inability to fix oxygen
in the blood.
    Nutrients are difficult to control
because lake and estuarine ecosys-
tems recycle nutrients. Rather than
leaving the ecosystem, the nutrients
cycle among the water column,
algae and plant tissues, and the
bottom sediments. For example,
algae may temporarily remove all
the nitrogen from the water col-
umn, but the nutrients will return to
the water column when the algae
die and are decomposed by bacte-
ria. Therefore, gradual inputs of
nutrients tend to accumulate over
time rather than leave the system.

Sediment and Siltation
    In a water quality context, sedi-
ment usually refers to soil particles
that enter the water column from
eroding land. Sediment consists of
particles of all sizes, including fine
clay particles, silt, sand,  and gravel.
Water quality managers use the
                                                                                                           ES-9

-------
  term "siltation" to describe the sus-
  pension and deposition of small
  sediment particles in waterbodies.
      Sediment and siltation can
  severely alter aquatic communities.
  Sediment may clog and abrade fish
  gills, suffocate eggs and aquatic
  insect larvae on the bottom, and fill
  in the pore space between  bottom
  cobbles where fish lay eggs. Silt and
  sediment interfere with recreational
  activities and aesthetic enjoyment at
  waterbodies by reducing water clar-
  ity and filling in waterbodies. Sedi-
  ment may also carry other pollut-
  ants into waterbodies. Nutrients and
  toxic chemicals may attach to sedi-
  ment particles on land  and ride the
  particles into surface waters where
  the pollutants may settle with the
  sediment or detach and become
  soluble in the water column.
      Rain  washes silt and other soil
  particles off of plowed fields, con-
  struction sites, logging sites, urban
  areas, and strip-mined lands into
  waterbodies. Eroding stream banks
  also deposit silt and sediment in
  waterbodies. Removal of vegetation
  on shore can accelerate streambank
  erosion.

  Bacteria and Pathogens

      Some waterborne bacteria,
  viruses, and protozoa cause human
  illnesses that range from typhoid
  and dysentery to minor respiratory
  and skin diseases. These organisms
  may enter waters through a number
  of routes, including inadequately
  treated sewage, stormwater drains,
  septic systems, runoff from livestock
  pens, and sewage dumped  over-
  board from recreational boats.
  Because it is impossible to test
  waters for every possible
disease-causing organism, States
and other jurisdictions usually mea-
sure indicator bacteria that are
found in great numbers in the
stomachs and intestines of warm-
blooded animals and people. The
presence of indicator bacteria sug-
gests that the waterbody may be
contaminated with untreated
sewage and that other, more
dangerous organisms may be
present. The States, Tribes, and
other jurisdictions use bacterial crite-
ria to determine if waters are safe
for recreation and shellfish  harvest-
ing.

Toxic Organic Chemicals
and Metals

    Toxic organic chemicals are
synthetic compounds that contain
carbon, such as polychlorinated
biphenyls (PCBs),  dioxins, and the
pesticide DDT. These synthesized
compounds often persist and
accumulate in the environment
because they do not readily break
down in natural ecosystems. Many
of these compounds cause cancer
in people and birth  defects in other
predators near the top of the food
chain, such as birds and fish.
    Metals occur naturally in the
environment, but human activities
(such as industrial processes and
mining) have altered the distribu-
tion of metals in the environment.
In most reported cases of metals
contamination, high concentrations
of metals appear in  fish tissues
rather than the water column be-
cause the metals accumulate in
greater concentrations in predators
near the top of the food chain.

PH
    Acidity, the concentration of
hydrogen ions, drives many chemi-
cal  reactions in living organisms.
The standard measure of acidity is
ES-10

-------
pH, and a pH value of 7 represents
a neutral condition. A low pH value
(less than 5) indicates acidic condi-
tions;  a high pH (greater than 9)
indicates alkaline conditions.  Many
biological processes, such as
reproduction, cannot function in
acidic or alkaline waters. Acidic con-
ditions also aggravate toxic contami-
nation problems because sediments
release toxicants in acidic waters.
Common sources of acidity include
mine  drainage,  runoff from mine
tailings,  and atmospheric deposition.

Habitat Modification/
Hydrologic Modification
    Habitat modifications include
activities in the  landscape, on shore,
and in waterbodies that alter the
physical structure of aquatic
ecosystems and have adverse
impacts on aquatic life. Examples of
habitat modifications include:

•  Removal of streamside vegetation
that stabilizes the shoreline and
provides shade, which moderates
instream temperatures

•  Excavation of cobbles from a
stream bed that provide nesting
habitat for fish

•  Stream burial

•  Excessive suburban sprawl that
alters the natural drainage patterns
by increasing the intensity, magni-
tude, and energy of runoff waters.

ming, and dredging.

    Other pollutants include salts
and oil and grease. Fresh waters
may become unfit for aquatic life
and some human uses when they
become contaminated by salts.
Sources of salinity include irrigation
runoff, brine used in  oil extraction,
road deicing operations, and the
intrusion  of sea water into ground
and surface waters in coastal areas.
Crude oil  and processed petroleum
products may be spilled during
extraction, processing, or transport
or leaked from underground storage
tanks.

Sources  of
Water Pollution

    Sources of impairment gener-
ate the pollutants that violate use
support criteria (Table ES-3). Point
sources discharge pollutants directly
into surface waters from a convey-
ance. Point sources include indus-
trial facilities,  municipal sewage
treatment plants,  and combined
sewer overflows. Nonpoint sources
deliver pollutants  to surface waters
from diffuse origins.  Nonpoint
sources include urban runoff, agri-
cultural runoff, and atmospheric
deposition of contaminants in air
pollution. Habitat alterations, such
as hydromodification, dredging, and
streambank destabilization, can also
degrade water quality.

         (obtained from the Section 305(b)
         reports submitted by the States,
         Tribes, and other jurisdictions). Note
         that the cause and source rankings
         do not describe the condition of all
         waters in the United States because
         the States identify the causes and
         sources degrading  some of their
         impaired waters, which are a small
         subset of surveyed waters, which
         are a subset of the Nation's total
         waters. For example, the States
         identified  sources degrading some
         of the 224,236 impaired  river miles,
         which represent 36% of the sur-
         veyed  river miles and only 6% of
         the Nation's total stream miles.

              storm water discharges
              and return flows  from
               irrigated agriculture."

           Clean Water Act Section 502(14)
Table ES-4 lists the leading sources
of impairment related to human
activities as reported by States,
Tribes, and other jurisdictions for
their rivers, lakes, and estuaries.
Other sources cited include removal
of riparian vegetation, forestry activi-
ties, land disposal,  petroleum extrac-
tion and processing activities, and
construction. In addition to human
activities, the States, Tribes, and
other jurisdictions also reported
impairments from natural sources.
Natural sources refer to an assort-
ment of water quality problems:

•  Natural deposits of salts, gypsum,
nutrients, and metals in soils that
leach into surface and ground
waters

•  Warm weather and dry condi-
tions that raise water temperatures,
depress dissolved oxygen concen-
trations, and dry up shallow
waterbodies

•  Low-flow conditions and tannic
acids from decaying leaves that
lower pH and dissolved oxygen
concentrations in swamps draining
into streams.

   With so many potential sources
of pollution, it is difficult and
expensive for States, Tribes, and
other jurisdictions to identify specific
sources responsible for water quality
impairments.  Many States and other
jurisdictions lack funding for moni-
toring to identify all but the most
apparent sources degrading
waterbodies. Local management
priorities  may focus monitoring
budgets on other water quality
issues, such as identification of con-
taminated fish populations that pose
a human health risk. Management
priorities  may also direct monitoring
efforts to larger waterbodies and
overlook  sources impairing smaller
waterbodies. As a result, the States,
Tribes, and other jurisdictions do
not associate every impacted
waterbody with a source of impair-
ment in their 305(b) reports, and
the summary cause and source
information presented in this report
applies exclusively to a subset of the
Nation's  impaired waters.

Rivers  and  Streams
    Rivers and streams are charac-
terized by flow.  Perennial rivers and
streams flow continuously, all year
round. Nonperennial rivers and
streams stop flowing for some
period of time, usually due to dry
conditions or upstream withdrawals.
Many rivers and streams originate in
nonperennial headwaters that flow
only during snowmelt or heavy
showers.  Nonperennial streams
provide critical habitats for nonfish
species, such as amphibians and
dragonflies, as well as safe havens
for juvenile fish to escape from
predation by larger fish.   ,
    The health of rivers and streams
is directly linked to habitat integrity
on shore and in adjacent wetlands.
Stream quality will deteriorate if
activities  damage shoreline (i.e.,
riparian)  vegetation and wetlands,
which filter pollutants from runoff
and bind soils. Removal of
vegetation also eliminates shade
that moderates stream temperature
as well as the land temperature that
can  warm runoff entering surface
waters. Stream temperature, in turn,
affects the availability of dissolved
oxygen in the water column for fish
and other aquatic organisms.

Overall Water Quality

     For the  1994 Report, 58 States,
Territories, Tribes, Commissions, and
the  District of Columbia surveyed
615,806 miles (17%) of the  Nation's
total 3.5 million miles of rivers and
streams (Figure ES-2). The surveyed
rivers and streams represent 48% of
the 1.3 million  miles of perennial
rivers and streams that flow year
round in the lower 48 States.
    Altogether, the States and
Tribes surveyed 27,075 fewer river
miles in 1994 than in 1992. Indi-
vidually, most States reported that
they surveyed more river miles in
1994, but their increases were offset
by a decline of 85,000 surveyed
river miles reported by Montana,
Mississippi, and Maryland. For 1994,
these States reported use support
status for only those river miles that
they surveyed in direct monitoring
programs or evaluations rather than
using  inferences for unsurveyed
waters.
    The following discussion applies
exclusively to surveyed waters and
cannot be extrapolated to describe
conditions in the Nation's rivers as a
whole because the States, Tribes,
and other jurisdictions do not con-
sistently use statistical or probabil-
istic survey methods to characterize
all their waters at this time.  EPA is
working with the States, Tribes, and
                                    other jurisdictions to expand survey
                                    coverage of the Nation's waters and
                                    expects future survey information to
                                    cover a greater portion of the
                                    Nation's rivers and streams.

             Of the Nation's 615,806
          surveyed river miles, the States,
          Tribes, and other jurisdictions found
          that 64% have good water quality.
          Of these waters, 57% fully support
          their designated uses, and an addi- .
          tional 7% support uses but are
          threatened and may become
          impaired if pollution control actions
          are not taken (Figure ES-3).
             Some form of pollution or
          habitat degradation prevents the
          remaining 36% (224,236 miles) of
          the surveyed river miles from fully
          supporting a healthy aquatic com-
          munity or human activities all year
          round. Twenty-two  percent of the
          surveyed river  miles have fair water
          quality that partially supports desig-
          nated uses. Most of the time, these
          waters provide adequate habitat for
          aquatic organisms and support hu-
          man activities,  but periodic pollution
          interferes with  these activities and/or
          stresses aquatic life.  Fourteen per-
          cent of the surveyed river miles
          have poor water quality that  consis-
          tently stresses aquatic life and/or
          prevents people from using the river
         for activities such as swimming and
         fishing.

         What Is Polluting Our
          Rivers and Streams?

          .  The States  and Tribes report
         that bacteria pollute 76,397 river
         miles (which equals 34% of the
         impaired river miles) (Figure ES-4).
         Bacteria provide evidence of pos-
         sible fecal contamination that may
         cause illness if the public ingests the
         water.
            Siltation, composed of tiny soil
         particles, remains one of the most
         widespread pollutants impacting
 rivers and streams. The States and
 Tribes reported that siltation impairs
 75,792 river miles (which equals
 34% of the impaired river miles).


   Bacteria and siltation are
     the most widespread
    pollutants in rivers and
  streams, affecting 34% of
   the impaired river miles.


 Siltation alters aquatic habitat and
 suffocates fish eggs and bottom-
 dwelling organisms. Excessive silt-
 ation can also interfere with drink-
 ing water treatment processes and
 recreational use of a river.
    In  addition to siltation and bac-
 teria, the States and Tribes also
 reported that nutrients, oxygen-
 depleting substances, metals, and
 habitat alterations impact more
 miles of rivers and streams than
 other pollutants and processes.
 Often,  several pollutants and
 processes impact a single river seg-
 ment. For example, a process, such
 as removal  of shoreline vegetation,
 may accelerate erosion of sediment
 and nutrients into a stream.

 Where Does This
 Pollution Come From?

    The States and Tribes reported
 that agriculture is the most wide-
 spread  source of pollution in the
 Nation's surveyed  rivers (Figure
 ES-4). Agriculture generates pollut-
 ants that degrade  aquatic life or
 interfere with public use of 134,557
 river miles (which equals 60% of
the impaired river miles) in 49
States and Tribes.
    Twenty-one States reported the
 size of rivers impacted by specific
 types of agricultural activities:

 • Nonirrigated Crop Production -
 crop production that relies on rain
 as the sole source of water.

 • Irrigated Crop Production - crop
 production that uses irrigation
 systems to supplement rainwater.

 • Rangeland - land grazed by ani-
 mals that is seldom enhanced  by
 the application of fertilizers or  pesti-
 cides, although managers some-
 times modify plant species to a lim-
 ited extent.

 • Pastureland - land upon which a
 crop (such as alfalfa) is raised to
 feed animals, either by grazing the
 animals among the crops or har-
 vesting the crops.

 • Feedlots - facilities where animals
 are fattened and confined at high
 densities.

 • Animal Holding Areas - facilities
 where animals are confined briefly
 before slaughter.

    The States reported that
 nonirrigated crop production im-.
 paired the most river miles, followed
 by irrigated crop production, range-
land, feedlots, pastureland, and
animal holding areas.
    Many States reported declines
in pollution from sewage treatment

  source of impairment in
     the Nation's rivers,
    affecting 60% of the
    impaired river miles.

plants and industrial discharges as a
result of sewage treatment plant
construction and upgrades and
permit controls on industrial
discharges.  Despite the improve-
ments, municipal sewage treatment
plants remain the second most
common source of pollution in
rivers (impairing 37,443 miles) be-
cause population growth increases
the burden  on our municipal facili-
ties.
    Hydrologic modifications and
habitat alterations are a growing
concern  to the States. Hydrologic
modifications include activities  that
alter the flow of water in a stream,
such as channelization, dewatering,
and damming of streams. Habitat
alterations include removal of
streamside vegetation that protects
the stream from high temperatures,
and scouring of stream bottoms.
Additional gains in water quality
conditions will be more subtle  and
require innovative management
strategies that go beyond point
source controls.
    The  States, Tribes, and other
jurisdictions also reported that  urban
runoff and storm sewers impair
26,862 river miles (12% of the
impaired rivers), resource extraction
impairs 24,059 river miles (11% of
the impaired rivers), and removal
of streamside vegetation impairs
21,706 river miles (10% of the
impaired rivers).
    The  States, Tribes, and other
jurisdictions  also report that "natu-
ral" sources  impair significant
stretches of  rivers and streams.
"Natural" sources, such as low  flow
and soils with arsenic deposits,  can
prevent waters from supporting uses
in the absence of human activities.

   Lakes,   Ponds,  and  Reservoirs
      Lakes are sensitive to pollution
  inputs because lakes flush out their
  contents relatively slowly. Even
  under natural conditions, lakes
  undergo eutrophication, an aging
  process that slowly fills in the lake
  with sediment and organic matter
  (see sidebar). The eutrophication
  process alters basic lake characteris-
  tics such as depth, biological pro-
  ductivity, oxygen levels, and water
  clarity. The eutrophication process is
  commonly defined by a series of
  trophic states as described in the
  sidebar.

  Overall Water  Quality

      Forty-eight States, Tribes, and
  other jurisdictions surveyed overall
  use support in more than 17.1 mil-
  lion lake acres representing 42% of
  the approximately 40.8 million total
  acres of lakes, ponds, and reservoirs
  in the Nation (Figure ES-5). For
  1994, the States surveyed about
  1 million fewer lake acres than in
  1992.
      The number of surveyed lake
  acres declined because several States
  separated fish tissue  data from their
  survey of overall use support. Some
  of these States, such as Minnesota,
  have established massive databases
  of fish tissue contamination informa-
  tion (which is used to establish fish
  consumption advisories), but lack
  other types of water quality data for
  many of their lakes. In 1994, these
  States chose not to assess overall
  use support entirely with fish tissue
  data alone, which is  a very narrow
  indicator of water quality.
      The States and Tribes reported
  that 63% of their surveyed 17.1
  million lake acres have good water
quality. Waters with good quality
include 50% of the surveyed lake
acres fully supporting uses and 13%
of the surveyed lake acres that are
threatened and might deteriorate if
we fail to manage potential sources
of pollution (Figure ES-6).
    Some form of pollution or
habitat degradation impairs the
remaining 37% of the surveyed lake
acres. Twenty-eight percent of the
surveyed lake acres have fair water
quality that partially supports desig-
nated uses.  Most of the time,  these
waters provide adequate habitat for
aquatic organisms and  support
human activities,  but periodic pollu-
tion interferes with these activities
and/or stresses aquatic  life. Nine
percent of the  surveyed lake acres
suffer from poor water  quality that
consistently stresses aquatic life and/
or prevents  people from using the
lake for activities such as swimming
and fishing.

What Is Polluting Our
Lakes, Ponds, and
Reservoirs?

    Forty-one States, the District of
Columbia, and  Puerto Rico reported
the number of  lake acres impacted
by individual pollutants and
processes.
    Thirty-seven States and Puerto
Rico identified more lake acres pol-
luted by nutrients than any other
pollutant or process (Figure ES-7).
                                     The States and Puerto Rico reported
                                     that extra nutrients pollute 2.8 mil-
                                     lion lake acres (which equals 43% of
                                     the impaired lake acres). Healthy
                                     lake ecosystems contain nutrients in
                                     small quantities, but extra inputs of
                                     nutrients from human activities
                                     unbalance lake ecosystems.
                                         In addition to nutrients, the
                                     States, Puerto Rico,  and the District
                                     of Columbia report that siltation

      Eutrophication is a natural process, but human activities can
  accelerate eutrophication by Increasing the rate at which nutrients and
^ organic substances enter lakes from their surrounding watersheds. Agri-
fc'culturaj rjunoff, urban Vunoff, leaking septic systems, sewage discharges,
  eroded streambanks, and similar sources can enhance the,.flow of nutri-
2~ents anjdhprganic substances into lakes. These substances ca,n pver-

wastes that deplete oxygen impacts
1.6 million lake acres (which equals
24% of the impaired lake acres),
and metals pollute 1.4 million acres
(which equals 21% of the impaired
lake acres).
    Metals declined from the most

     Increases in lake acidity can

      adverse effects. Twenty-
' eight States reported the results
 of lake acidification assessments.
ifsThese States assessed pH (a
"measure of acidity) at  more than
 5,933 lakes and detected acidic
' conditions in 526 lakes and a
. threat of acidic conditions in 423
1 lakes. Most of the States that
.assessed acidic conditions are
•Jocated in the Northeast, upper
. Midwest, and the South.
j;;t' Only 11 States identified
 sources of acidic conditions.
,Maine and New Hampshire
 attributed most of their acid  lake
 conditions to acid deposition
from acidic  rain, fog, or dry
deposition in conjunction with
natural conditions that limit a
lake's capacity to neutralize
acids. Alabama, Kansas, Mary-
land, Montana, Oklahoma, and
•Tennessee reported that acid
mine drainage resulted in acidic
lake conditions or threatened
lakes with the potential to gen-
erate acidic  conditions.

          to the fourth leading pollutant
          impairing lakes in 1994. The decline
          is due to changes in State reporting
          and assessment methods  rather
          than a measured decrease in metals
          contamination. In 1994, several
          States chose to no longer assess
          overall use support with fish con-
          tamination data alone.  Much of
          that data consisted of measure-
          ments of metals in fish  tissue. As a
          result of excluding these fish tissue
          data, the national estimate of lake
          acres impaired by metals  fell by
          over 2 million acres in 1994.
               More States reported
                impairments due to
             nutrients than any other
                  single pollutant.


               Forty-one States also surveyed
           trophic status, which is associated
           with nutrient enrichment, in 9,735
           of their lakes. Nutrient enrichment
           tends to increase the proportion  of
           lakes in the eutrophic and hyper-
           eutrophic categories. These States
           reported that 18% of the lakes they
           surveyed for trophic status were
           oligotrophic, 32% were mesotro-
           phic, 36% were eutrophic, 6% were
           hypereutrophic, and  3% were dys-
           trophic. This information may not
           be representative of national lake
           conditions because States often
           assess lakes in response to a prob-
           lem or public complaint or because
           of their easy accessibility. It is likely
           that more remote lakes—which
           are probably less impaired—are
           underrepresented in these
           assessments.

Where Does This
Pollution Come From?

    Forty-two States and Puerto
Rico reported sources of pollution in
some of their impacted lakes,
ponds, and reservoirs. These States
and Puerto Rico reported that agri-
culture is the most widespread
source of pollution in the Nation's
surveyed, lakes (Figure ES-7). Agricul-
ture generates pollutants that de-
grade aquatic life or interfere with
public use of 3.3 million lake acres
(which equals 50% of the impaired
lake acres).


  Agriculture is the leading
   source of impairment in
   lakes, affecting 50% of
     impaired lake acres.


    The States and Puerto Rico also
reported that municipal sewage
treatment plants pollute 1.3 million
lake acres (19% of the  impaired lake
acres), urban runoff and storm
sewers pollute 1.2 million lake acres
(18% of the surveyed lake acres),
unspecified nonpoint sources impair
989,000 lake acres (15% of the
impaired lake acres), hydrologic
modifications and habitat alterations
degrade 832,000 lake acres (12% of
the impaired lake acres), and indus-
trial point sources pollute 759,000
lake acres (11% of the impaired lake
acres). Many States prohibit new
point source discharges into lakes,
but existing municipal sewage treat-
ment plants remain a leading source
of pollution entering lakes.
    The States and Puerto Rico
listed numerous sources that impact
several hundred thousand lake
acres, including  land disposal of
wastes, construction, flow regula-
tion, highway maintenance and
runoff, contaminated sediments,
atmospheric deposition of pollut-
ants, and onsite wastewater systems
(including septic tanks).
                                                                                                     ES-19

 The  Great  Lakes
     The Great Lakes contain one-
  fifth of the world's fresh surface
  water and are stressed by a wide
  range of pollution sources, including
  air pollution. Many of the pollutants
  that reach the Great Lakes remain in
  the system indefinitely because the
  Great Lakes are a relatively closed
  water system with few  natural
  outlets. Despite dramatic declines in
  the occurrence of algal blooms, fish
  kills, and localized "dead" zones
  depleted of oxygen, less visible
  problems continue to degrade the
  Great Lakes.

  Overall Water Quality

     The States surveyed 94% of the
  Great Lakes shoreline miles for 1994
  and reported that fish consumption
  advisories and aquatic life concerns
  are the dominant water quality
  problems, overall, in the Great Lakes
  (Figure ES-8). The States reported
  that most of the  Great Lakes
  nearshore waters are safe for swim-
  ming and other recreational activi-
  ties and can be used as a source of
  drinking water with normal treat-
  ment. However, only 2% of the
  surveyed nearshore waters fully sup-
  port designated uses, overall, and
  1 % support uses but are threatened
  (Figure ES-9). About 97% of the
  surveyed waters do not fully support
  designated uses,  overall, because
  fish consumption advisories are
  posted throughout the nearshore
  waters of the Great Lakes and water
  quality conditions are unfavorable
  for supporting aquatic life in many
  cases. Aquatic life impacts result
  from  persistent toxic pollutant bur-
  dens  in birds, habitat degradation
  and destruction,  and competition

 Considerable progress has
  been made in controlling
   conventional  pollutants,
   but the Great Lakes are
  still subject to the effects
      of toxic pollutants.


These figures do not address water
quality conditions in the deeper,
cleaner, central  waters of the Lakes.

What Is Polluting
the Great Lakes?

    The States reported that most
of the Great Lakes shoreline is
polluted by toxic organic chemicals-
primarily PCBs-that are often found
in fish tissue samples. The Great
Lakes States reported that toxic
organic chemicals impact 98% of
the impaired Great Lakes shoreline
miles. Other leading causes of
impairment include  pesticides,
affecting  21 %; nonpriority organic
chemicals, affecting  20%; nutrients,
affecting  6%; and metals, affecting
6% (Figure ES-10).

   Where Does This
   Pollution Come From?

       Only four of the eight Great
   Lakes States measured the size of
   their Great Lakes shoreline polluted
   by specific sources. These States have
   jurisdiction over one-third of the
   Great Lakes shoreline, so their
   findings do not necessarily reflect
   conditions throughout the Great
   Lakes Basin.

   •  Wisconsin identifies air pollution
   and discontinued discharges as a
   source of pollutants contaminating
   all 1,017 of their surveyed shoreline
   miles. Wisconsin also identified
   smaller areas impacted by
   contaminated sediments, nonpoint
   sources, industrial and municipal
   discharges, agriculture, urban runoff
   and storm sewers, combined sewer
   overflows, and land disposal of
   waste.

   •  Indiana attributes all of the
   pollution along its entire 43-mile
   shoreline to air pollution, urban
   runoff and storm sewers, industrial
   and municipal discharges, and
   agriculture.

   • Ohio reports that nonpoint
   sources pollute 86 miles of its 236
   miles of shoreline, in-place
   contaminants impact 33 miles, and
   land disposal of waste impacts 24
   miles of shoreline.

   • New York identifies many sources
   of pollutants in their Great Lakes
   waters, but the State attributes the
   most miles of degradation to
   contaminated sediments (439 miles)
   and land disposal of waste (374
   miles).

Estuaries
    Estuaries are areas partially sur-
rounded by land where rivers meet
the sea. They are characterized by
varying degrees of salinity, complex
water movements affected by ocean
tides and river currents, and high
turbidity levels. They are also highly
productive ecosystems with a range
of habitats for many different
species of plants, shellfish, fish,
and animals.
    Many species permanently
inhabit the estuarine ecosystem;
others, such as shrimp, use the
nutrient-rich estuarine waters as
nurseries before  traveling to the sea.
    Estuaries are stressed by the
particularly wide range of activities
located within their watersheds.
They receive pollutants carried by
rivers from agricultural lands and
cities;  they often support marinas,
harbors, and commercial fishing
fleets; and their  surrounding lands
are highly prized for development.
These stresses pose a continuing
threat to the survival of these
bountiful waters.

Overall Water Quality

    Twenty-five coastal States and
jurisdictions surveyed 78% of the
Nation's total  estuarine waters in
1994  (Figure ES-11). The States  and
other jurisdictions reported that
63% of the surveyed estuarine
waters have good water quality  that
fully supports designated uses
 (Figure ES-12). Of these waters,  6%
are threatened and might deterio-
 rate if we fail  to manage potential
 sources of pollution.

                                                      78% Surveyed
    Some form of pollution or
habitat degradation impairs the
remaining 37% of the surveyed
estuarine waters. Twenty-seven
percent of the surveyed estuarine
waters have fair water quality that
partially supports designated uses.
Most of the time these waters pro-
vide adequate habitat for aquatic
organisms and support human
activities,  but periodic pollution
interferes  with these activities and/or
stresses aquatic life. Nine percent of
the surveyed estuarine waters suffer
from poor water quality that consis-
tently stresses aquatic life and/or
prevents people from using the
estuarine waters for activities such as
swimming and shellfishing.

   What Is Polluting
   Our Estuaries?
       The States identified more
   square miles of estuarine waters
   polluted by nutrients and bacteria
   than any other pollutant or process
   (Figure  ES-13). Fifteen States
   reported that extra nutrients pollute
   4,548 square miles of estuarine
   waters (which equals 47% of the
   impaired estuarine waters). As in
lakes, extra inputs of nutrients from
human activities destabilize estua-
rine ecosystems.
    Twenty-five States reported that
bacteria pollute 4,479 square miles
of estuarine waters (which equals
46% of the impaired estuarine
waters). Bacteria provide evidence
that an estuary is contaminated
with sewage that may contain
numerous viruses and bacteria that
cause illness in people.
    The States also report that oxy-
gen depletion from organic wastes
impacts 3,127 square miles (which
equals 32% of the impaired
estuarine waters), habitat alterations
impact 1,564 square miles (which
equals 16% of the impaired estua-
rine waters), and oil and grease
pollute 1,344 square miles (which
equals 14% of the impaired estua-
rine waters.

Where Does This
Pollution Come From?

    Twenty-three States reported
that urban runoff and storm sewers
are the most widespread source of
pollution in the Nation's surveyed
estuarine waters. Pollutants in urban
runoff and storm sewer effluent
degrade aquatic life or interfere with
public use of 4,508 square miles  of
estuarine waters (which equals 46%
of the impaired estuarine waters)
(Figure ES-13).
    The States also reported that
municipal sewage treatment plants
pollute 3,827 square miles of estua-
rine waters (39% of the impaired
estuarine waters), agriculture pol-
lutes 3,321 square miles of estuarine
waters (34% of the impaired estua-
rine waters), and industrial dis-
charges pollute 2,609 square miles
(27% of the impaired estuarine
waters). Urban sources contribute
more to the degradation of estua-
rine waters than agriculture because
urban centers are located adjacent
to most major estuaries.

    Ocean  Shoreline Waters
       Although the oceans are expan-
   sive, they are vulnerable to pollution
   from numerous sources, including
   city storm sewers, ocean outfalls
   from sewage treatment plants, over-
   board disposal  of debris and sew-
   age, oil spills, and bilge discharges
   that contain oil and grease.
   Nearshore ocean waters, in particu-
   lar, suffer from  the same pollution
   problems that degrade our inland
   waters.

   Overall Water Qualify

      Thirteen of the 27 coastal States
   and Territories surveyed only 9% of
   the Nation's estimated 58,421 miles
   of ocean coastline (Figure ES-14).
   Most of the surveyed waters (4,834
   miles, or 93%)  have good quality
   that supports a  healthy aquatic
   community and public activities
   (Figure ES-15). Of these waters, 225
   miles (4% of the surveyed shoreline)
   are threatened and may deteriorate
   in the future.
      Some form  of pollution or habi-
   tat degradation  impairs the
   remaining 7% of the surveyed
   shoreline (374 miles). Five percent
   of the surveyed  estuarine waters
   have fair water quality that partially
   supports designated uses.  Most of
   the time, these waters provide
   adequate habitat for aquatic organ-
   isms and support human activities,
   but periodic pollution interferes with
   these activities and/or stresses
   aquatic life. Only 2% of the sur-
   veyed shoreline  suffers from poor
   water quality that consistently
   stresses aquatic life and/or prevents
   people from using the shoreline for
 activities such as swimming and
 shellfishing.
    Only six of the 27 coastal States
 identified pollutants and sources of
 pollutants degrading ocean shore-
 line waters. General conclusions
 cannot be drawn from the informa-
 tion supplied by these States
 because these States border less
 than 1 % of the  shoreline along the
 contiguous States. The six States
 identified impacts in their ocean
 shoreline waters from bacteria, met-
 als, nutrients, turbidity, siltation, and
 pesticides. The six States reported
that urban runoff and storm sewers,
industrial discharges, land disposal
of wastes, septic systems, agricul-
ture, unspecified nonpoint sources,
and combined sewer overflows
(CSOs) pollute their coastal shore-
line waters.

Wetlands
    Wetlands are areas that are
inundated or saturated by surface
water or ground water at a fre-
quency and duration sufficient to
support (and that under normal
circumstances does support) a
prevalence of vegetation typically   .
adapted for life in saturated soil
conditions. Wetlands, which are
found throughout the United States,
generally include swamps^marshes,
bogs, and similar areas.
    Wetlands are now recognized  as
some of the most unique and
important natural areas on earth.
They vary in type according to dif-
ferences in local and .regional
hydrology, vegetation, water chem-
istry, soils, topography, and climate.
Coastal wetlands include estuarine
marshes; mangrove swamps found
in Puerto Rico, Hawaii, Louisiana,
and Florida; and Great Lakes coastal
wetlands. Inland wetlands, which
may be  adjacent to a waterbody or
isolated, include marshes and wet
meadows,  bottomland hardwood
forests, Great Plains prairie potholes,
cypress-gum swamps, and south-
western playa lakes.
     In their natural condition,
wetlands provide many benefits,
including food and habitat for fish
and wildlife, water quality improve-
 ment, flood protection, shoreline
erosion control, ground  water
 exchange, as well as natural
 products for human use and oppor-
tunities for recreation, education,
 and research.
     Wetlands help maintain and
 improve water quality by intercept-
 ing surface water runoff before it
 reaches  open water, removing or
 retaining nutrients, processing
 chemical and organic wastes, and
reducing sediment loads to
receiving waters. As water moves
through a wetland, plants slow the
water, allowing sediment and pol-
lutants to settle out. Plant roots trap
sediment and are then able to
metabolize and detoxify pollutants
and remove nutrients such as nitro-
gen and phosphorus.
    Wetlands function like natural
basins, storing either floodwater that
overflows riverbanks or surface
water that collects in isolated
depressions. By doing so, wetlands
help protect adjacent and
downstream property from flood
damage. Trees and other wetlands
vegetation help slow the speed of
flood waters. This action, combined
with water storage, can lower flood
heights and  reduce the water's
erosive potential. In  agricultural
areas, wetlands can  help reduce the
likelihood of flood damage to crops.
Wetlands within and upstream  of
urban areas are especially valuable
for flood protection because urban
development increases the rate and
volume of surface water runoff,
thereby increasing the risk of flood
damage.
    Wetlands produce a wealth of
natural products, including fish and
shellfish, timber, wildlife, and wild
rice. Much of the Nation's fishing
and shellfishing industry harvests
wetlands-dependent species.  A
national survey conducted by the
Fish and Wildlife  Service (FWS) in
1991  illustrates the economic value
of some of the wetlands-dependent
products. Over 9 billion pounds of
fish and shellfish  landed in the
United States in 1991 had a direct,
dockside value of $3.3 billion. This
served as the basis of a seafood
processing and sales industry that
generated total expenditures of
$26.8 billion. In addition, 35.6 mil-
lion anglers spent $24 billion on
freshwater and saltwater fishing. It is
estimated that 71% of commercially
                                                                                                        ES-27

   valuable fish and shellfish depend
   directly or indirectly on coastal
   wetlands.

   Overall Water Quality

      The States, Tribes, and other
   jurisdictions are making progress in
   developing specific designated uses
   and water quality standards for wet-
   lands, but many States and Tribes
   still lack specific water quality crite-
   ria and monitoring programs for
   wetlands. Without criteria and
   monitoring data, most States and
   Tribes cannot evaluate use support.
   To date, only nine States and Tribes
   reported the designated use support
   status for some of  their wetlands.
   Only one State used quantitative
   data as a basis for  the use  support
   decisions.
      EPA cannot derive national con-
   clusions about water quality condi-
   tions in all wetlands because the
   States used different methodologies
   to survey only 3%  of the total
   wetlands in the Nation. Summariz-
   ing State wetlands data would also
   produce misleading results because
   two States (North Carolina and
   Louisiana) contain 91 % of  the
   surveyed wetlands  acreage.

   What Is Polluting Our
   Wetlands and Where
   Does This Pollution
   Come From?

      The States have even fewer data
   to quantify the extent of pollutants
   degrading wetlands and the sources
   of these pollutants. Although most
   States cannot quantify wetlands area
   impacted by individual causes and
sources of degradation, 12 States
identified causes and 13 States iden-
tified sources known to degrade
wetlands integrity to some extent.
These States listed sediment as the
most widespread cause of degrada-
tion impacting wetlands, followed
by flow alterations, habitat modifica-
tions, and draining (Figure ES-16).
Agriculture topped the list of
sources degrading wetlands, fol-
lowed  by urban runoff, hydrologic
modification, and municipal point
sources (Figure ES-17).

Wetlands Loss:
A Continuing Problem

    It is estimated that over 200
million acres of wetlands existed  in
the lower 48 States at the time of
European settlement. Since then,
extensive wetlands acreage has
been lost, with many of the original
                                    wetlands drained and converted to
                                    farmland and urban development.
                                    Today, less than half of our original
                                    wetlands remain. The losses amount
                                    to an area equal to the size of Cali-
                                    fornia. According to the U.S. Fish
                                    and Wildlife Service's Wetlands Losses
                                    in the United States 1780's to 1980's,
                                    the three States that have sustained
                                    the greatest percentage of wetlands
                                    loss are California (91 %), Ohio
                                    (90%), and Iowa (89%).
                                        According to FWS status and
                                    trends reports, the average annual
                                    loss of wetlands has decreased over
                                    the past 40 years. The average
                                    annual loss from the mid-1950s to
                                    the mid-1970s was 458,000 acres,
                                    and from the mid-1970s to the mid-
                                    1980s it was 290,000 acres. Agricul-
                                    ture was responsible for 87% of the
                                    loss from the  mid-1950s to the mid-
                                    1970s and 54% of the loss from the
                                    mid-1970s to the mid-1980s.

    A more recent estimate of
wetlands losses from the National
Resources Inventory (NRI), con-
ducted by the Natural Resources
Conservation Service (NRCS), indi-
cates that 792,000 acres of wet-
lands were lost on non-Federal lands
between 1982 and 1992 for a
yearly loss estimate of 70,000 to
90,000 acres. This net loss is the
result of gross losses  of 1,561,300
acres of wetlands and gross gains of
768,700 acres of wetlands over the
10-year period. The NRI estimates
are consistent with the trend of
declining  wetlands losses reported
by FWS. Although losses have
decreased, we still have to make
progress toward our interim goal of
no overall net loss of the Nation's
remaining wetlands and the long-
term goal of increasing the quantity
and quality of the Nation's wetlands
resource base.
    The decline in wetlands losses is
a result of the combined effect of
several trends: (1) the decline in
profitability in converting wetlands
for agricultural production;
(2) passage of Swampbuster provi-
sions in the 1985 and 1990 Farm
Bills that denied crop subsidy ben-
efits to farm operators who con-
verted wetlands to cropland after
1985; (3) presence of the CWA
Section 404 permit programs as
well as development of State man-
agement programs; (4) greater

    Nineteen States listed sources of

ment and urban growth were cited
as the leading sources of current
losses. Other losses were due to
commercial development; construc-
tion of roads, highways, and
bridges; agriculture; and industrial
development. In addition to human
activities, a few States also reported
that natural sources,  such as rising
lake levels,  resulted in wetlands
losses and degradation.

   Ground  Water
      Ninety-five percent of all fresh
  water available on earth (exclusive
  of icecaps) is ground water. Ground
  water-water found in natural under-
  ground rock formations called aqui-
  fers-is a vital natural resource with
  many uses. The extent of the
  Nation's ground water resources is
  enormous. At least 60% of the land
  area in the conterminous United
  States overlies aquifers that may be
  susceptible to contamination. Usable
  ground water exists in every State.
      Aquifers can range in size from
  thin surficial formations that yield
  small quantities of ground water to
  large systems such as the High
  Plains aquifer that underlies eight
  western States and provides water
  to millions. Although the Nation's
  ground water is of good quality, it
  Is recognized that ground water is
  more vulnerable to contamination
  than previously reported and that
  an increasing number of pollution
  events and contamination sources
  are threatening the integrity of the
  resource.

  Ground Water Use

      Nationally, 51% of the popula-
  tion relies to some extent on
  ground water as a source of drink-
  ing water. This percentage is even


     Ground water provides
     drinking water for 51%
        of the population.


  higher in rural areas where most
  residents rely on potable or treat-
  able ground water as an economical
  source of drinking water. Eighty-one
  percent of community water
systems are dependent on ground
water. Seventy-four percent of
community water systems are small
ground water systems serving 3,300
people or less. Ninety-five percent
of the approximately 200,000
noncommunity water systems (serv-
ing schools, parks, and other small
facilities)  are ground water systems.
    Irrigation accounts for approxi-
mately 63% of national ground
water withdrawals. Public drinking
water supplies account for approxi-
mately 19% of the Nation's total
ground water withdrawals. Domes-
tic, commercial, livestock, industrial,
mining, and thermoelectric with-
drawals together account for
approximately 18% of national
ground water withdrawals.

Ground Water Quality

    Although the 1994 Section
305(b) State Water Quality Reports
'indicate that, overall, the Nation's
ground water is of good quality,
 many local areas have experienced
 significant ground water contamina-
 tion. The sources and types of
 ground water contamination vary
 depending upon the region of the
 country. Those most frequently
 reported  by States include:

 • Leaking underground storage
 tanks. Approximately 1.2 million
 federally regulated underground
 storage tanks are buried at over
 500,000 sites nationwide. An esti-
 mated  139,000 tanks have leaked
 and impacted ground water quality.

 • Agricultural activities. Seventy-
 seven percent of the 1.1 billion
 pounds of pesticides produced
 annually in the United States is
 applied to land in agricultural
 production, which usually overlies
 aquifers.

 • Superfund sites. More than 85%
 of all Superfund sites have some
 degree of ground water contamina-
 tion. Most of these sites impact
 aquifers that are currently used, or
 potentially may be used, for drink-
 ing water purposes.

 • Septic tanks. Approximately 23
 million  domestic septic tanks are in
 operation in the United States.
These tanks impact ground water
quality  through the discharge of
fluids into or above aquifers.

   The most common contami-
 nants associated with these sources
include petroleum compounds,
nitrates, metals, volatile organic
compounds (VOCs), and pesticides.
   States are reporting that ground
water quality is most likely to be
adversely affected by contamination
in areas of high demand or stress.
ES-30

-------
To combat these problems, States
are developing programs designed
to evaluate the overall quality and
vulnerability of their ground water
resources, to identify potential
threats to ground water quality, and
to identify methods to protect their
ground water resources. Thirty-three
States indicate that they have imple-
mented statewide ground water
monitoring programs.
    Ground water monitoring pro-
grams vary widely among the
States, depending  upon the special
needs of each of the States. For
example, some States choose to
monitor ground water quality in
specific areas that are especially
vulnerable to contamination,
whereas other States may choose to
monitor ground water quality on a
statewide basis. When it comes to
selecting chemicals to test for in the
ground water, some States monitor
for a large suite of chemicals,
whereas other States limit monitor-
ing to one or two specific chemicals
that are a definite threat to ground
water quality.
    Ground water monitoring pro-
vides a great deal  of information
about the nature and quality of our
Nation's ground water resources.
Still, there is much we do not know
about how human activities influ-
ence ground water quality. Our
continued quest for information
about the status of our ground wa-
ter will help protect and preserve
this vast and vulnerable resource.
Through a greater understanding of
 how human activities influence
 ground water quality, we can better
 ensure the long-term availability of
 high-quality water for future
 generations.

   Water Quality  Protection  Programs
      Although significant strides have
   been made in reducing the impacts
   of discrete pollutant sources, our
   aquatic resources remain at risk
   from a combination of point
   sources and complex nonpoint
   sources, including air pollution.
   Since 1991, EPA has promoted the
   watershed protection approach as a
   holistic framework for addressing
   complex pollution problems.
      The watershed protection
   approach is a place-based strategy
   that integrates water quality man-
   agement activities within hydrologi-
   cally defined drainage basins-
   watersheds-rather than areas
   defined by political boundaries.
   Thus, for a given watershed, the
   approach encompasses not only the
   water resource (such as a stream,
   lake, estuary, or ground water aqui-
   fer), but all the land from which
   water drains to the resource. To
      Under the Watershed
       Protection Approach
      (WPA), a "watershed"
     is a hydrogeologic area
     defined for addressing
     water quality problems.
       For example, a WPA
    watershed may be a river
      basin, a county-sized
      watershed, or a small
      drinking water supply
            watershed.
  protect water resources, it is increas-
  ingly important to address the con-
  dition of land areas within the
watershed because water carries the
effects of human activities through-
out the watershed as it drains off
the land into surface waters or
leaches into the ground water.
    EPA's Office of Water envisions
the watershed protection  approach
as the primary mechanism for
achieving clean water and healthy,
sustainable ecosystems throughout
the Nation. The watershed protec-
tion approach enables stakeholders
to take a comprehensive look at
ecosystem issues and tailor correc-
tive actions to local concerns within
the coordinated framework of a
national water program. The
emphasis on public participation
also provides an opportunity to
incorporate environmental justice
issues into watershed restoration
and protection solutions.
    In May of 1994, the EPA Assis-
tant Administrator for Water, Robert
Perciasepe, created the Watershed
 Management Policy Committee to
 coordinate the EPA water program's
 support of the watershed protection
 approach.  During 1995, EPA's water
 program managers, under the direc-
 tion of the Watershed Management
 Policy Committee, evaluated their
 programs and identified additional
 activities needed to support the
 watershed  protection approach in
 an action plan.
    EPA's Office of Water will con-
 tinue to promote and support the
 watershed  protection approach at
 local, State, Tribal, Territorial,  and
 Federal levels. The Office of Water
 recognizes  that the watershed
 protection  approach relies on active
 participation by local governments
 and citizens who have the most
 direct knowledge of local problems
 and opportunities in their water-
sheds. However, the Office of Water
will look to the States, Tribes, and
Territories to create the framework
ES-32

-------
for supporting local efforts because
most EPA programs are imple-
mented by the States, Tribes, and
Territories.

The Clean Water Act

    A number of laws provide the
authority to develop and implement
pollution control programs. The
primary statute providing for water
quality protection in the Nation's
rivers, lakes, wetlands, estuaries, and
coastal waters is  the Federal Water
Pollution Control Act of 1972, com-
monly known as the Clean Water
Act.
    The CWA and its amendments
are the driving force behind many
of the water quality improvements
we have witnessed in  recent years.
Key provisions of the CWA provide
the following pollution control
programs.

    Water quality standards and
    criteria - States, Tribes, and
    other jurisdictions adopt EPA-
    approved standards for their
    waters that define water quality
    goals for individual waterbodies.
    Standards consist of designated
     beneficial uses to  be made of
    the water, criteria to protect
    those uses, and antidegradation
     provisions to protect existing
    water quality.

     Effluent guidelines - The EPA
     develops nationally consistent
     guidelines limiting pollutants in
     discharges from industrial
    facilities and municipal sewage
     treatment plants.  These guide-
     lines are then used  in permits
     issued  to dischargers under the
  "The Watershed  Protection Approach (WPA)

 Several key principles guide the watershed protection approach:
 * - Hlpa" *<^.t£tJf
-------
       National Pollutant Discharge
       Elimination System (NPDES)
       program. Additional controls
       may be required if receiving
       waters are still affected by water
       quality problems after permit
       limits are met.

       Total Maximum Daily Loads-
       The development of Total Maxi-
       mum Daily Loads, or TMDLs,
       establishes the link between
       water quality standards and
       point/nonpoint source pollution
       control actions such as permits
       or Best Management Practices
       (BMPs). A TMDL calculates
       allowable loadings from the
       contributing point and
       nonpoint sources to a given
       waterbody and provides the
       quantitative basis for pollution
       reduction necessary to meet
       water quality standards. States,
       Tribes, and other jurisdictions
       develop and implement TMDLs
       for high-priority impaired or
       threatened waterbodies.

       Permits and enforcement - All
       industrial and municipal facilities
       that discharge wastewater must
       have an NPDES permit and are
       responsible for monitoring and
       reporting levels of pollutants in
       their discharges. EPA issues
       these permits or can delegate
       that permitting authority to
       qualifying States or other juris-
       dictions. The States, other quali-
      fied jurisdictions, and EPA
 inspect facilities to determine if
 their discharges comply with
 permit limits. If dischargers are
 not in compliance, enforcement
 action is taken.

 Grants - The EPA provides
 States with financial assistance
 to help support many of their
 pollution control programs.
 These programs include the
 State Revolving Fund program
 for construction and upgrading
 of municipal sewage treatment
 plants; water quality monitor-
 ing, permitting, and enforce-
 ment; and developing and
 implementing nonpoint source
 pollution controls, combined
 sewer and stormwater controls,
 ground water strategies, lake
 assessment,  protection, and
 restoration activities, estuary
 and near coastal management
 programs, and wetlands protec-
 tion activities.

 Nonpoint source control - The
 EPA provides program guid-
 ance, technical support, and
funding to help the States,
Tribes, and other jurisdictions
control nonpoint source  pollu-
tion. The States, Tribes, and
other jurisdictions are respon-
sible for analyzing the extent
and severity  of their nonpoint
source pollution problems and
developing and implementing
needed water quality manage-
ment actions.
     The CWA also established
 pollution control and prevention
 programs for specific waterbody
 categories, such as the Clean Lakes
 Program. Other statutes that also
 guide the development of water
 quality protection programs include:

 • The Safe Drinking Water Act,
 under which States establish
 standards for drinking water quality,
 monitor wells and local water
 supply systems, implement drinking
 water protection  programs, and
 implement Underground Injection
 Control (UIC) programs.

 • The Resource Conservation and
 Recovery Act, which establishes
 State and EPA programs for ground
 water and surface water protection
 and cleanup and  emphasizes pre-
 vention of releases through man-
 agement standards in addition to
 other waste management activities:

 • The Comprehensive Environ-
 mental Response, Compensation,
 and Liability Act (Superfund
 Program), which provides EPA with
 the authority to clean up  contami-
 nated waters during remediation at
 contaminated sites.

 • The Pollution  Prevention Act
 of 1990, which requires EPA to
 promote pollutant source reduction
 rather than focus on controlling
pollutants after they enter the
environment.

 Protecting Lakes

     Managing lake quality often
 requires a combination of in-lake
 restoration measures and pollution
 controls, including watershed man-
. agement measures:

     Restoration measures are
     implemented  to reduce existing
     pollution problems.  Examples of
     in-lake restoration measures
     include harvesting aquatic
     weeds, dredging sediment, and
     adding chemicals to precipitate
     nutrients out  of the  water col-
     umn. Restoration measures
     focus on restoring uses of a lake
     and may not  address the source
     of the pollution.

     Pollution control measures
     deal with the sources of pollut-
     ants degrading  lake water
    quality or threatening to impair
    lake water quality. Control mea-
    sures include planning activities,
    regulatory actions, and imple-
    mentation of BMPs to reduce
    nonpoint sources of pollutants.

    During the 1980s, most States
implemented chemical and
mechanical in-lake restoration
measures to control aquatic weeds
and algae. In their 1994 Section
305(b) reports, the States and
Tribes report a shift toward
nonpoint source controls to reduce
pollutant loads responsible for
aquatic weed growth and algal
blooms (Figure ES-18). Twenty-two
States reported that they imple-
mented best management practices
to control nonpoint source pollution
entering more than 171 lakes.
The States reported that they

implemented agricultural practices

and constructed or restored wet-

that they still use in-lake treatments,
the States recognize that source
controls are needed in addition to
in-lake treatments to restore lake
water quality.
    Successful lake programs require
strong commitment from local citi-
zens and cooperation from natural
resource agencies at the  local, State,
and Federal levels.

   The National Estuary
   Program

      Section 320 of the Clean Water
   Act (as amended by the Water
   Quality Act of 1987) established the
   National Estuary Program (NEP) to
   protect and restore water quality
   and living resources in estuaries. The
   NEP adopts a geographic or water-
   shed approach by planning and
   implementing pollution abatement
   activities for the estuary and its
   surrounding land area as a whole.
      The NEP embodies the ecosys-
   tem approach by building coali-
   tions, addressing multiple sources of
   contamination, pursuing habitat
   protection as a pollution control
   mechanism, and investigating cross-
   media transfer of pollutants from air
   and soil into specific  estuarine
waters. Under the NEP, a State gov-
ernor nominates an estuary in his or
her State for participation in the
program. The State must demon-
strate a likelihood of success in pro-
tecting candidate estuaries and pro-
vide evidence  of institutional, finan-
cial,  and political commitment to
solving estuarine problems.
    If an estuary meets the NEP
guidelines, the EPA Administrator
convenes a management
conference of  representatives from
interested Federal, Regional, State,
and  local governments; affected
industries; scientific and academic
institutions; and citizen organiza-
tions. The management conference
defines program goals and objec-
tives, identifies problems, and
designs strategies to control pollu-
tion  and manage natural resources
 in the estuarine basin. Each man-
 agement conference develops and
 initiates implementation of a Com-
 prehensive Conservation and Man-
 agement Plan (CCMP) to restore
 and protect the estuary.


 The NEP currently supports
      28 estuary projects.


    The NEP integrates science and
 policy by bringing water quality
 managers, elected officials, and
 stakeholders together with scientists
 from government agencies, aca-
 demic institutions, and the private
 sector. Because the NEP is not a
 research program, it relies heavily
 on past and ongoing research of
 other agencies and institutions to
 support development of CCMPs.
    With the addition of seven estu-
 ary sites in July of 1995, the NEP
 currently supports 28 estuary
 projects (see Figure ES-19). These
 28 estuaries are nationally significant
 in their economic value as well as in
 their ability to support living
 resources. The project sites also
 represent a broad range of environ-
 mental conditions in estuaries
throughout the United States and
 its Territories so that the lessons
 learned through the NEP can be
applied to other estuaries.

    Shortly after coming into
office, the Clinton Administration
convened an interagency working
group to address concerns with
Federal wetlands policy. After hear-
ing from States, developers, farm-
ers, environmental interests, mem-
bers of Congress, and scientists,
the working group developed a
comprehensive 40-point plan for
wetlands protection to make wet-
lands programs more fair, flexible,
and effective. This plan was issued
on August 24,  1993.
    The Administration!s Wetlands
Plan emphasizes improving Federal
wetlands policy by
•  Streamlining wetlands permit-
   ting programs
•  Increasing cooperation with
   private landowners to protect
   and restore wetlands
•  Basing wetlands protection on
   good science and sound
   judgment
•  Increasing participation by
   States, Tribes, local govern-
   ments, and  the public in
   wetlands protection.
Protecting Wetlands

    A variety of public and private
programs protect wetlands. Section
404 of the CWA continues to pro-
vide the primary Federal vehicle for
regulating certain activities in wet-
lands. Section  404 establishes a
permit program for discharges of
dredged  or fill material into waters
of the United States, including
wetlands.
    The U.S. Army Corps of Engi-
neers (COE) and EPA jointly imple-
ment the Section 404 program. The
COE is responsible for reviewing
permit applications and making
permit decisions.  EPA establishes the
environmental criteria for making
permit decisions and has the
authority to review and veto Section
404 permits proposed for issuance
by the COE. EPA is also responsible
for determining geographic jurisdic-
tion of the Section 404 permit
program, interpreting statutory
exemptions, and  overseeing Section
404 permit programs assumed by
individual States.  To date, only two
States (Michigan  and New  jersey)
have assumed the Section 404 per-
mit program from the COE. The
COE and EPA share responsibility for
enforcing Section 404 requirements.
    The COE issues individual Sec-
tion 404 permits for specific projects
or general permits (Table ES-5).
Applications for individual permits
go through a review process that
includes opportunities for EPA, other
Federal agencies (such as the  U.S.
Fish and Wildlife Service and the
National Marine Fisheries Service),
State agencies, and the public to
comment.  However,  the vast  major-
ity of activities proposed in wetlands
are covered by Section 404 general
permits. For example, in FY94, over
48,000 people applied to the COE
for a Section  404 permit. Eighty-two
percent of these applications were
covered by general permits and
were processed in an average of 16
days. It is  estimated that another
50,000 activities are  covered by
general permits that do not require
notification of the COE at all.
    General permits  allow the COE
to permit certain activities without
performing a separate individual

          permit review. Some general
          permits require notification of the
          COE before an activity begins. There
          are three types of general permits:

          • Nationwide permits (NWPs)
          authorize specific activities across
          the entire Nation that the COE
          determines will have only minimal
          individual and cumulative impacts
          on the environment, including con-
          struction of minor road crossings
          and farm buildings, bank stabiliza-
          tion activities, and the filling of up
          to 10 acres of isolated or headwater
          wetlands.

          • Regional permits authorize types
          of activities within a geographic
          area defined  by a COE District
          Office.

          • Programmatic general permits
          are issued to an entity that the COE
          determines may regulate activities
          within its jurisdictional wetlands.
          Under a programmatic general per-
          mit, the COE defers its permit deci-
          sion to the regulating entity but
          reserves its authority to require an
          individual permit.

             Currently, the COE and EPA are
          promoting the development of
         State programmatic general permits
         (SPGPs) to increase State involve-
         ment in wetlands protection and
         minimize duplicative State and Fed-
         eral review of activities proposed in
         wetlands.  Each SPGP is a unique
         arrangement developed by a State
         and the COE to take advantage of
         the strengths of the individual  State
         wetlands program. Several States
         have adopted comprehensive SPGPs
         that replace many or all COE-issued
         nationwide general permits. SPGPs
simplify the regulatory process and
increase State control over their
wetlands resources. Carefully devel-
oped SPGPs can improve wetlands
protection while reducing regulatory
demands on landowners.
    Water quality standards for
wetlands ensure that the provisions
of CWA Section 303 that apply to
other surface waters are also applied
to wetlands. In July 1990, EPA
issued guidance to States for the
development of wetlands water
quality standards. Water quality
standards consist of designated ben-
eficial uses, numeric criteria,  narra-
tive criteria, and antidegradation
statements. Figure ES-20 indicates
the State's progress in developing
these standards.
    Standards provide the founda-
tion for a broad range of water
quality management activities under
the CWA including, but not limited
to, monitoring for the Section
305(b) report, permitting under
Section 402 and 404, water quality
certification under Section 401, and
the control of nonpoint source pol-
lution under Section 319.
    States, Territories, and Tribes are
well positioned between Federal
and local government to take the
lead in integrating and expanding
wetlands protection and manage-
ment programs. They are experi-
enced in managing federally man-
dated environmental programs, and
they are uniquely equipped to help
resolve local and regional conflicts
and identify the local economic and
geographic factors that  may influ-
ence wetlands protection.
    Section 401 of the CWA gives
States and eligible American Indian
Tribes the authority to grant, condi-
tion, or deny certification of feder-
ally permitted or licensed activities
that may result in a discharge to
U.S. waters, including wetlands.
Such activities include discharge of
dredged or fill material permitted
under CWA Section 404, point
source discharges permitted under
CWA Section 402, and Federal
Energy Regulatory Commission's

 hydropower licenses. States review
 these permits to ensure that they
 meet State water quality standards.
    Section 401 certification can be
 a powerful tool for protecting wet-
 lands from unacceptable degrada-
 tion or destruction especially when
 implemented in conjunction with
.wetlands-specific water quality stan-
 dards. If a State or an eligible Tribe
 denies Section  401 certification, the
 Federal permitting or licensing
 agency cannot issue the permit or
 license.
    Until recently, many States
 waived their right to review and
 certify Section 404 permits because
 these States had not defined water
 quality standards for wetlands or
 codified regulations for implement-
 ing their 401 certification program
 into State law.  Now, most States
 report that they use the  Section
 401 certification process to review
 Section 404 projects and to require
 mitigation if there is no alternative
 to degradation of wetlands. Ideally,
 401 certification should be used to
 augment State programs because
 activities that do not require  Federal
 permits or licenses, such as some
 ground water withdrawals, are not
 covered.
    State Wetlands Conservation
 Plans (SWCPs)  are strategies that
 integrate regulatory and coopera-
 tive approaches to achieve State
 wetlands management goals, such
 as no overall net loss of wetlands.
 SWCPs are not meant  to create a
 new level of bureaucracy. Instead,
 SWCPs improve government and
 private-sector effectiveness and
 efficiency by identifying gaps in
 wetlands protection programs and
 identifying opportunities to improve
 wetlands programs.
    States, Tribes, and other juris-
dictions protect their wetlands with
a variety of other approaches, in-
cluding permitting programs,
coastal management programs,
wetlands acquisition programs,
natural heritage programs, and inte-
gration with other programs. The
following trends emerged from
individual State and Tribal  reporting:

•  Most States have defined wet-
lands as waters of the State, which
offers general protection through
antidegradation clauses and desig-
nated uses that apply to all waters
of a State. However, most  States
have not developed specific wet-
lands water quality standards and
designated uses that protect wet-
lands' unique functions, such as
flood attenuation and filtration.

•  Without specific wetlands uses
and standards, the Section 401
certification process relies heavily on
antidegradation clauses to  prevent
significant degradation of wetlands.

•  In many cases, the States use the
Section 401  certification process to
add conditions to Section 404
permits that minimize the  size of
wetlands destroyed or degraded by
proposed activities to the extent
practicable. States  often add condi-
tions that require compensatory
mitigation for destroyed wetlands,
but the States  do not have the
resources to perform enforcement
inspections or followup monitoring
to ensure that the  wetlands are
constructed and functioning
properly.

•  More States are monitoring
selected, largely unimpacted
wetlands to establish baseline
conditions in healthy wetlands. The
States will use this information to
monitor the relative performance of
constructed  wetlands and to help
establish  biocriteria and water qual-
ity standards for wetlands.

    Although the States, Tribes, and
other jurisdictions report that they
are making progress in protecting
wetlands, they also report that the
pressure to develop or destroy wet-
lands remains high. EPA and the
States,  Tribes, and other jurisdictions
will continue to pursue new mecha-
nisms for protecting wetlands that
rely less on regulatory tools.

Protecting the
Great  Lakes

    Restoring and protecting the
Great Lakes  requires cooperation
from numerous organizations be-
cause the pollutants that enter the
Great Lakes  originate in both the
United States and Canada, as well
as in other countries. The Interna-
tional joint Commission (IjC), estab-
lished by the 1909 Boundary Waters
Treaty, provides a framework for the
cooperative  management of the
Great Lakes. Representatives from
the United States and Canada, the
Province  of Ontario, and the eight
States bordering the Lakes sit on the
IJC's Water Quality Board. The
Water Quality Board recommends
actions for protecting  and restoring
the Great Lakes and evaluates the
environmental policies and actions
implemented by the United  States
and Canada.
    The EPA Great Lakes National
Program  Office (GLNPO) coordi-
nates Great  Lakes management
                                                                                                          ES-39

-------
   activities conducted by all levels of
   government within the United
   States. The GLNPO also works with
   nongovernmental organizations to
   protect and restore the Lakes. The
   GLNPO provides leadership through
   its annual Great Lakes Program Priori-
   ties and Funding Guidance. The
   GLNPO also serves as a liaison to
   the Canadian  members of the IJC
   and the Canadian environmental
   agencies.
      The 1978 Great Lakes Water
   Quality Agreement (as amended in
   1987) lay the  foundation for on-
   going efforts to restore and protect
   the Great Lakes. The Agreement
   committed  the United States  and
   Canada to developing Remedial
   Action Plans (RAPs) for Areas of
   Concern and Lakewide Manage-
   ment Plans  (LaMPs) for each Lake.
   Areas of Concern are specially desig-
   nated waterbodies around the Great
   Lakes that show symptoms of seri-
   ous water quality degradation. Most
   of the 42 Areas of Concern are
   located in harbors, bays, or river
   mouths entering the Great Lakes.
   RAPs identify impaired uses and
   examine management options for
   addressing degradation in an  Area
   of Concern. LaMPs use an ecosys-
   tem approach to examine water
   quality issues that have more wide-
   spread impacts within each Great
   Lake. Public involvement is a critical
   component of both LaMP develop-
   ment and RAP development.
      EPA advocates pollution preven-
   tion as the most effective approach
   for achieving the virtual elimination
   of persistent toxic discharges into
   the Great Lakes. The GLNPO has
   funded numerous pollution preven-
   tion grants throughout the Great
Lakes Basin during the past 3 years.
EPA and the States also imple-
mented the 38/50 Program in the
Great Lakes Basin, under which EPA
received voluntary commitments
from industry to reduce the emis-
sion of 17 priority pollutants by
50% by the end of 1995. In addi-
tion, EPA, the States, and Canada
are implementing a virtual elimina-
tion initiative for Lake Superior. The
first phase of the initiative seeks to
eliminate new contributions of
mercury.
    The Great Lakes Water Quality
Initiative is a key element of the
environmental protection efforts
undertaken by the United States in
the Great Lakes Basin. The purpose
of the Initiative is to provide a
consistent level of protection in the
Basin from the effects of toxic
pollutants. In 1989, the Initiative
was organized by EPA at the request
of the Great Lakes States to
promote consistency  in their
 environmental programs in the
 Great Lakes Basin with minimum
 requirements.
    Initiative efforts were well under
 way when Congress enacted the
 Great Lakes Critical Programs Act of
 1990. The Act requires EPA to pub-
 lish proposed and final water quality
 guidance that specifies minimum
 water quality criteria for the Great
 Lakes System. The Act also  requires
 the Great Lakes States to adopt
 provisions that are consistent with
 the EPA final guidance within 2
 years of EPA's publication.  In addi-
 tion, Indian Tribes  authorized to
 administer an NPDES program in
 the Great.Lakes Basin  must also
 adopt provisions consistent with
 EPA's final guidance.
    To carry out the Act, EPA pro-
 posed regulations for implementing
 the guidance on April 16, 1993,
 and invited the public to comment.
 The States  and EPA conducted pub-
 lic meetings in all of the Great Lakes
 States during the comment period.
 As a result, EPA received over
 26,500 pages of comments from
 over 6,000 commenters. EPA
 reviewed all of the comments and
 published the final guidance in
 March of 1995.
    The final guidance prioritizes
 control of long-lasting pollutants
 that accumulate  in the food web—
 bioaccumulative  chemicals of con-
 cern (BCCs). The final guidance
 includes provisions to phase out
 mixing zones for BCCs (except in
 limited circumstances), more exten-
 sive data requirements to ensure
that BCCs are not underregulated
 due to a  lack of data, and water
quality criteria to protect wildlife
that feed on aquatic prey.

Publication of the final guidance is a
milestone in  EPA's move toward
increasing stakeholder participation
in the development of innovative
and comprehensive programs for
protecting and restoring our natural
resources.

The Chesapeake Bay
Program

    In many areas of the Chesa-
peake Bay, the quality is not suffi-
cient to support living resources
year round. In the warmer months,
large portions of the  Bay contain
little or no dissolved oxygen. Low
oxygen  conditions  may cause fish
eggs and larvae to die. The growth
and reproduction of oysters, clams,
and other bottom-dwelling animals
are impaired. Adult fish find their
habitat reduced and their feeding
inhibited.
    Many areas of the Bay also have
cloudy water from excess sediment
in the water or an  overgrowth of
algae (stimulated by excessive nutri-
ents in the water). Turbid waters
block the sunlight  needed to sup-
port the growth  and survival of Bay
grasses, also known as submerged
aquatic vegetation (SAV). Without
SAV, critical  habitat for fish and
crabs is lost. Although there has
been a recent resurgence of SAV in
some areas of the  Bay, most areas
still do not support abundant popu-
lations as they once did.
    The main causes of  the Bay's
poor water quality and aquatic habi-
tat loss  are elevated levels of the
nutrients nitrogen  and phosphorus.
Both are natural fertilizers found in
animal wastes, soil, and  the atmos-
phere. These nutrients have always
existed in the Bay, but not at the
present elevated concentrations.
When the Bay was surrounded pri-
marily by forests and wetlands, very
little nitrogen and phosphorus ran
off the land into the water. Most of
it was absorbed or held in place by
the natural vegetation. As the use of
the land has changed and the
watershed's population has grown,
the amount of nutrients entering
the Bay has increased tremendously.
    Now in its twelfth year, the
Chesapeake Bay Program is a re-
gional  partnership of Federal, State,
and local participants that has di-
rected  and coordinated restoration
of the  Bay since the signing of the
historic 1983 Chesapeake Bay
Agreement. Maryland, Pennsylvania,
Virginia, the District of Columbia,
the Chesapeake Bay Commission,
EPA, and advisory groups form the
partnership. The Chesapeake Execu-
tive Council provides leadership for
the Bay Program and establishes
program policies to  restore and
protect the Bay and its living
resources. The Council consists of
the governors of Maryland, Virginia,
and Pennsylvania, the mayor of the
District of Columbia, the administra-
tor of EPA, and the chairperson of
the Chesapeake Bay Commission.
     Considered a national and inter-
national model for estuarine restora-
tion and protection  programs, the
Chesapeake Bay Program is still a
"work in progress."  Since 1983,
milestones in the evolution of the
program include the 1987 Chesa-
peake  Bay Agreement and the 1992
amendments to the Agreement. The
1987 Agreement set a goal to re-
duce the quantity of nutrients enter-
ing the Bay by 40% by the year
2000. In the 1992 amendments to
the Agreement, the partners reaf-
firmed the 40% nutrient reduction
goal, agreed to cap nutrient load-
ings beyond the year 2000, and
agreed to attack nutrients at their
source by applying the 40% reduc-
tion goal to the 10 major tributaries
of the Bay.  The amendments also
stressed managing the Bay as a
whole ecosystem. The amendments
also spell out the importance of
reducing atmospheric sources of
nutrients and broadening regional
interstate cooperation.
    Protection and restoration of
forests is a critical component of the
Chesapeake Bay Program because
scientific data clearly show that
forests are the most beneficial land
cover for maintaining clean water,
especially forests alongside
waterbodies in the riparian zone.
Through the  Chesapeake Bay Pro-
gram, unique partnerships have
been formed among the Bay
region's forestry agencies, forest
managers, and interested citizen
groups. Since 1990, the U.S. Forest
Service has assigned a Forestry Pro-
gram Coordinator to the Chesa-
peake Bay Program to assist both
the EPA and  Bay Program commit-
tees in developing strategies and
projects that  will contribute to the
Bay restoration goals. A  Forestry
Work Group, formed under the
Nonpoint Source Subcommittee,
raises and addresses issues related to
forests and the practice  of forestry
in the watershed.
    In addition, State foresters and
local governments have developed
and implemented numerous
programs and projects aimed at the
protection  and restoration of forests.
                                                                                                        ES-41

-------
   Forestry incentive programs in all of
   the Bay States have resulted in the
   planting of millions of trees, the
   restoration of nearly 50 miles of
   riparian forest, the development of
   stewardship plans, and forest
   enhancement projects on thousands
   of acres within the Bay watershed.
      On the positive side, the extent
   of Bay grasses has increased by 75%
   since 1978. The current extent of
   SAV attains 64% of the goal estab-
   lished by the Chesapeake Bay Pro-
   gram. Striped bass, or rockfish, have
   made a remarkable recovery over
   the past decade due to improved
   reproduction and better control of
   the harvest. There has been a mod-
   est increase in the number  of Ameri-
   can shad returning to the Bay to
   spawn.  Controls on the harvest of
   American shad, creation of  fish pas-
   sages at blockages, stocking pro-
   grams, and habitat restoration are
   expected to yield increases  in the
   American shad population and simi-
   lar fish species that inhabit the Bay
   during part of their life cycle.
      Phosphorus levels continue to
   decline and, after many years of
   increasing nitrogen concentrations,
   most of the Bay's tributaries are
   showing a  leveling off of this trend.
   Some tributaries are showing declin-
   ing trends in nitrogen concentra-
   tions. These trends indicate  that
   both point and nonpoint source
   pollution abatement programs are
   working.
      Despite the promising trends in
   nutrient concentrations, oxygen
   concentrations are still low enough
   to cause severe impacts or stressful
   conditions in the mainstem  of the
   Bay and several larger tributaries.
   Prospects for the Bay's oyster
ES-42
populations remain poor. Overhar-
vesting, habitat loss, and disease
have severely depleted oyster stocks.
New management efforts have been
developed to improve this situation.
    The blue crab is currently the
most important commercial and
recreational fishery in the Bay. There
is growing concern about the health
of the blue crab population due to
increasing harvesting pressures and
relatively low harvests in recent
years. Both Maryland and Virginia
have recently implemented new
regulations on commercial and rec-
reational crabbers to protect this
important resource.
    Overall, the Chesapeake Bay still
shows symptoms of stress from an
expanding population and changes
in  land use. However,  conditions in
the Chesapeake Bay have improved
since the Chesapeake Bay Program
was launched, and continuation of
the Program promises an even
brighter future for the Bay.
The Gulf of Mexico
Program

    The Gulf of Mexico Program
(GMP) was established in 1988 with
EPA as the lead Federal agency in
response to  signs of long-term envi-
ronmental damage throughout the
Gulf's coastal and marine ecosystem.
The main purpose of the GMP is to
develop and help implement a strat-
egy to protect, restore, and main-
tain the health and productivity  of
the Gulf. The GMP is a grass roots
program that serves as a catalyst to
promote sharing of information,
pooling of resources, and coordina-
tion of efforts to restore and reclaim
wetlands and wildlife habitat, clean
up existing pollution, and prevent
future contamination and destruc-
tion of the Gulf. The GMP mobilizes
State, Federal, and local govern-
ment; business and industry;
academia; and the community at

-------
large through public awareness and
information dissemination programs,
forum discussions, citizen commit-
tees, and technology applications.
    A Policy Review Board and the
Management Committee determine
the scope and focus of CMP activi-
ties. The program also receives
input from a Technical Advisory
Committee and a Citizen's Advisory
Committee.  The GMP Office, eight
technical issue committees, and the
operations and support committees
coordinate the collection, integra-
tion, and reporting of pertinent data
and information. The issue commit-
tees are composed of individuals
from Federal, State, and local agen-
cies and from industry, science,
education, business, citizen groups,
and private organizations.
    The issue committees are
responsible for documenting envi-
ronmental problems and manage-
ment goals, available resources, and
potential solutions for a  broad range
of issues, including habitat degrada-
tion, public  health, freshwater
inflow, marine debris, shoreline
erosion, nutrient enrichment, toxic
pollutants, and  living aquatic
resources. The issue committees
publish their findings in  Action
Agendas.
    On December 10, 1992, the
Governors of Alabama, Florida,
Louisiana, Mississippi, and Texas;
EPA; the Chair of the Citizen's Advi-
sory Committee; and representatives
of 10 other Federal agencies signed
the Gulf of Mexico Program Partner-
ship for Action  agreement for
protecting, restoring, and enhanc-
ing the Gulf of Mexico and adjacent
lands. The agreement committed
the signatory agencies to pledge
their efforts, over 5 years, to obtain
the knowledge and resources to:

•  Significantly reduce the rate of
loss of coastal wetlands

•  Achieve an increase in Gulf Coast
seagrass beds

•  Enhance the sustainability of,
Gulf commercial and recreational
fisheries

•  Protect human  health and food
supply by reducing input of nutri-
ents, toxic substances, and patho-
gens to the Gulf

•  Increase  Gulf shellfish beds avail-
able for safe harvesting by 10%

•  Ensure that all Gulf beaches are
safe for swimming and recreational
uses

•  Reduce by at least 10% the
amount of  trash on beaches

•  Improve and expand coastal
habitats that support migratory
birds, fish, and other living resources

•  Expand public education/out-
reach tailored for .each Gulf Coast
county or parish

•  Reduce critical coastal and shore-
line erosion.

    Beginning in 1992, the GMP
also launched Take-Action  Projects
in each of the five Gulf States to
demonstrate that program strategies
and methods could achieve rapid
results. The Take-Action Projects
primarily address inadequate
sewage treatment, pollution preven-
tion, and habitat protection and
restoration. Several projects aim to
demonstrate the effectiveness of
innovative sewage treatment tech-
nologies to control pathogenic con-
tamination of shellfish harvesting
areas.  Other projects aim to restore
wetlands, sea grass beds, and oyster
reefs. The Take-Action Projects are
designed to have Gulf-wide applica-
tion.
     Take-Action Projects
    in the five Gulf States
  primarily address sewage
     treatment, pollution
   prevention, and habitat
        protection and
          restoration.
    Since 1992, EPA has streamlined
and restructured its management
scheme for the GMP to increase
Regional involvement and better
meet the needs of the 5-year envi-
ronmental challenges. The GMP has
also expanded efforts to integrate
Mexico and the Caribbean Islands
into management of the Gulf. These
activities include technology transfer
and development of international
agreements that prohibit the
discharge of ship-generated wastes
and plastics into waters of the Gulf
and Caribbean Sea.

   Ground Water
   Protection Programs

      The sage adage that "An ounce
   of prevention is worth a pound of
   cure" is being borne out in the field
   of ground water protection. Studies
   evaluating the cost of prevention
   versus the cost of cleaning up con-
   taminated ground water have found
   that there are real cost advantages
   to promoting protection of our
   Nation's ground water resources.
      Numerous laws, regulations,
   and programs play a vital role in
   protecting ground water. The fol-
   lowing Federal laws and programs
   enable,  or provide incentives for,
   EPA and/or States to regulate or
   voluntarily manage and monitor
   sources  of ground water pollution:

   • The Resource Conservation and
   Recovery Act (RCRA) addresses the
   problem of safe disposal of the
huge volumes of solid and hazard-
ous waste generated nationwide
each year. RCRA is part of EPA's
comprehensive program to protect
ground water resources through the
development of regulations and
methods for handling, storing, and
disposing of hazardous material and
through the regulation of under-
ground storage tanks—the most
frequently cited  source of ground
water contamination.

• The Comprehensive  Environmen-
tal Response, Compensation, and
Liability Act (CERCLA) regulates the
restoration of contaminated ground
water at abandoned hazardous
waste sites.

• The Safe Drinking Water Act
(SDWA) regulates subsurface
injection of fluids that can contami-
nate ground water.

• The Federal Insecticide, Fungi-
cide, and Rodenticicle Act (FIFRA)
controls the use and disposal of
pesticides, some of which have
been detected in ground water
wells in rural communities.

• The Toxic Substances Control Act
(TSCA) controls the use and disposal
of additional toxic substances,
thereby minimizing their entry into
ground water. Other Federal laws
establish State grants that may be
used to protect ground water.

• Clean Water Act Sections 319(h)
and (i) and 518  provide funds to
State agencies to implement EPA-
approved nonpoint source
           Comprehensive State Ground Water
                    t Protection Programs

    Comprehensive State Ground Water Protection Program (CSGWPP)

management programs that include
ground water protection activities.
Several States have developed pro-
grams that focus on ground water
contamination resulting from
agriculture and septic tanks.

• The Pollution Prevention Act of
1990 allows grants for research
projects to demonstrate agricultural
practices that emphasize ground
water protection and reduce the
excessive use of fertilizers and
pesticides.

    Comprehensive State Ground
Water Protection Programs
(CSGWPPs) attempt to combine all
of the above efforts and emphasize
contamination prevention.


    Comprehensive State
  ground water protection
  programs support State-
     directed priorities in
     resource protection.

CSGWPPs improve coordination  of
Federal, State, Tribal, and local
ground  water programs and enable
distribution of resources to estab-
lished priorities.
    Another means of protecting
our Nation's ground water resources
is through the implementation of
Wellhead  Protection Plans.  EPA's
Office of Ground Water and Drink-
ing Water is supporting the
development and implementation
of Wellhead Protection  Plans at the
local level through many efforts. For
example,  EPA-funded support is
provided through the National Rural
Water Association Ground Water/
Wellhead Protection programs. At
the conclusion of the first 4 years of
this program, over 2,000 communi-
ties in 26 States were actively in-
volved in protecting their water
supplies by implementing wellhead
protection programs. These 2,000
communities represent almost 4
million people in the rural areas of
the United States who will have
better-protected  water supplies.
    Recognizing  the importance
and cost-effectiveness of protecting
our Nation's ground water
resources, States are participating in
numerous activities to prevent
future impairments of the resource.
These activities include enacting
legislation aimed at the develop-
ment of comprehensive State
ground water protection programs
and promulgating protection regu-
lations. More than 80% of the
States indicate that they have
current or pending legislation
geared specifically to ground water
protection. Generally, State legisla-
tion focuses on the need for pro-
gram development, increased data
collection, and public education
programs. In addition, States also
may mandate strict technical con-
trols such as discharge permits,
underground storage tank registra-
tions, and protection standards.
    All  of these programs are
intended to provide protection to a
valuable, and often vulnerable,
resource. Through the promotion of
ground water protection on both
State and Federal levels, our
Nation's ground water resources will
be safeguarded against contamina-
tion, thereby protecting human
health and the environment.
                                                                                                        ES-45

   What  You  Can  Do
       Federal and State programs
   have helped clean up many waters
   and slow the degradation of others.
   But government alone cannot solve
   the entire problem, and water qual-
   ity concerns persist Nonpoint
   source pollution, in particular, is
   everybody's problem, and every-
   body needs to solve it.
       Examine your everyday activities
   and think about how you are con-
   tributing to the pollution problem.
   Here are some suggestions on how
   you can make a difference.

   Be Informed

      You should learn about water
   quality issues that affect the com-
   munities in which you live and
   work. Become familiar with your
   local water resources. Where does
   your drinking water come from?
   What activities in your area might
   affect the water you drink or the
   rivers, lakes, beaches, or wetlands
   you use for recreation?
      Learn about procedures for
   disposing of harmful household
   wastes so they do not end up in
   sewage treatment plants that  can-
   not handle them or in landfills not
   designed to receive hazardous
   materials.

   Be Responsible

      In your yard, determine
   whether additional nutrients are
   needed before you apply fertilizers,
   and look for alternatives where fertil-
   izers might run off into surface
   waters. Consider selecting plants
   and grasses that have low mainte-
   nance requirements. Water your
   lawn conservatively. Preserve
   existing trees and plant new trees
and shrubs to help prevent erosion
and promote infiltration of water
into the soil. Restore bare patches in
your lawn to prevent erosion. If you
own or manage land through which
a stream flows, you may wish to
consult your local county extension
office about methods of restoring
stream banks in your area by plant-
ing buffer strips of native vegeta-
tion.
    Around your house, keep litter,
pet waste, leaves, and grass clip-
pings out of gutters and storm
drains. Use the minimum amount of
water needed when you wash your
car. Never dispose of any house-
hold, automotive, or gardening
wastes in a storm drain. Keep your
septic tank in good working order.
    Within your home, fix any drip-
ping faucets or leaky pipes and
install water-saving devices in
shower heads and toilets. Always
follow directions on labels for use
and disposal of household chemi-
cals. Take used  motor oil, paints,
 and other hazardous household
 materials to proper disposal sites
 such as approved service stations or
 designated landfills.

 Be Involved

    As a citizen and a voter there is
 much you can do at the community
 level to help preserve and protect
 our Nation's water resources. Look
 around. Is soil erosion being con-
 trolled at construction sites? Is the
 community sewage plant being
 operated efficiently  and  correctly? Is
 the community trash dump in or
 along a stream? Is road  deicing salt
 being stored properly?
    Become involved in  your com-
 munity election processes. Listen
 and respond to candidates' views
 on water quality and environmental
 issues.  Many communities have
 recycling programs; find out about
 them, learn how to recycle, and
 volunteer to help out if you can.
 One of the most important things
 you can do is find out how your
 community protects water quality,
 and speak out if you see problems.

 Volunteer Monitoring:
 You Can Become Part
 of the Solution

    In many areas of the country,
 citizens are becoming personally
 involved in monitoring the quality
 of our Nation's water. As a
volunteer monitor, you might be
 involved in taking ongoing water
 quality measurements, tracking the
 progress of protection and restora-
tion projects, or reporting special
events, such as fish kills and storm
damage.
ES-46

-------
    Volunteer monitoring can be of
great benefit to State and local  gov-
ernments. Some States stretch their
monitoring budgets by using data
collected by volunteers,  particularly
in remote areas that otherwise
might not be monitored at all.
Because you  are familiar with the
water resources in your own neigh-
borhood, you are also more likely to
spot unusual  occurrences such as
fish kills.                   :
    The benefits to you  of becom-
ing a volunteer are also great. You
will learn about your local water
resources and have the opportunity
to become personally involved in a
nationwide campaign to protect a
vital, and mutually shared, resource.

   Fish Consumption Advisories
       States issue fish consumption
   advisories to protect the public
   from ingesting harmful quantities
   of toxic pollutants in contaminated
   fish and shellfish. Fish may accumu-
   late dangerous quantities of pollut-
   ants in their tissues by ingesting
   many smaller organisms, each
   contaminated with a small quantity
   of pollutant. This process is called
   bioaccumulation or biomagnifica-
   tion. Pollutants also enter fish and
   shellfish tissues through the gills or
   skin.
       Fish consumption advisories
   recommend that the public limit the
   quantity and frequency of consump-
   tion of fish caught in specific
   waterbodies. The States tailor indi-
   vidual advisories to minimize health
   risks based on contaminant data
   collected in their fish tissue sam-
   pling programs. Advisories may
   completely ban fish consumption  in
   severely polluted waters, or limit fish
   consumption  to several  meals per
   month or year in cases of less severe
   contamination. Advisories may tar-
   get a subpopulation at risk (such as
   children, pregnant women, and
   nursing mothers), specific fish spe-
   cies, or larger fish that may have
   accumulated high concentrations  of
   a pollutant over a longer lifetime
   than a smaller, younger fish.
       The EPA fish consumption
   advisory database tracks advisories
   issued by each State. For 1994, the
   database listed 1,531 fish consump-
   tion advisories in effect in 49 States.
   Fish consumption advisories are
   unevenly distributed among the
States because the States use their
own criteria to determine if fish
tissue concentrations of toxics pose
a health risk that justifies an advi-
sory. States also vary the amount of
fish tissue monitoring they  conduct
and the number of pollutants ana-
lyzed. States that conduct more
monitoring and use strict criteria will
issue more advisories than States
that conduct less monitoring and
use weaker criteria. For example,
62% of the advisories active in 1994
were issued by the States surround-
ing the Great Lakes, which support
extensive fish sampling programs
and follow strict criteria for issuing
advisories.
    Most of the fish consumption
advisories (73%) are due to mer-
cury. The other pollutants mosf~
commonly detected in elevated
concentrations in fish tissue samples
are polychlorinated biphenyls
(PCBs), chlordane, dioxins, and DDT:
(with its byproducts).
    Many coastal States report
restrictions on shellfish harvesting in
estuarine waters. Shellfish-particu-
larly oysters, clams, and mussels-
are filter-feeders that extract their
food from water. Waterborne bacte-
ria and viruses may also accumulate
on their gills and mantles and  in
their digestive systems. Shellfish
contaminated by these microorgan-
isms are a serious human health
concern, particularly if consumed
raw.
    States currently sample water
from shellfish harvesting  areas  to
measure indicator bacteria, such as
total coliform and fecal coliforrn
bacteria. These bacteria serve as   V
indicators of the presence of poten-
tially pathogenic microorganisms
associated with  untreated or
undertreated sewage. States restrict
shellfish harvesting to areas that
maintain these bacteria at concen-
trations in sea water below estab-
lished health limits.
  ;  In 1994, "IS States reported that
shellfish harvesting restrictions  were
in effect for more than 6,052 square
miles of estuarine and coastal waters
during the 1992-1994 reporting
period. Six States reported that
urban runoff and storm sewers,
municipal wastewater treatment
facilities, nonpoint sources, marinas,
iricfustriai discharges, CSOs, and
septic tanks restricted shellfish
harvesting.

Introduction
Purpose
    The National Water Quality
Inventory Report to Congress is the
primary vehicle for informing Con-
gress and the public about general
water quality conditions in the
United States. This document char-
acterizes whether waters are meet-
ing water quality standards, identi-
fies widespread water quality prob-
lems of national significance, and
describes various programs imple-
mented to restore and protect our
waters.
    This document, the tenth in a
series published since 1975, satisfies
reporting requirements in Section
305(b) of the Clean Water Act
(CWA),  formally known as the Fed-
eral Water Pollution Control Act
Amendments of 1972 (Public Law
92-500). Section 305(b) requires
that States and other jurisdictions
survey the health of their surface
waters every 2 years and submit
biennial reports describing their
water quality conditions to the U.S.
Environmental Protection Agency
(EPA). Section  305(b) also requires
that EPA summarize the reports
submitted by the States, Tribes, and
other jurisdictions and convey the
information to Congress on a bien-
nial schedule.
    The National Water Quality
Inventory Report to Congress is a
compilation of information reported
by States, Tribes, and other jurisdic-
tions. As such, this report identifies
water quality issues of concern  to
the States, Tribes, and other jurisdic-
tions, not just the issues of concern
to EPA. This report summarizes the
water quality assessment informa-
tion submitted by 61 States, Ameri-
can Indian Tribes, Territories, Inter-
state Water Commissions, and the
District of Columbia in their 1994
Section 305(b) reports. Most of the
survey information in the 1994 Sec-
tion 305(b) reports is based on
water quality information collected
and evaluated during 1992 and
1993.
    It is important to note that the
States, Tribes, and other jurisdictions
do not use identical survey methods
and criteria to rate their water qual-
ity. They favor flexibility in the
305(b) process to accommodate
natural variability in their waters,
but there is a tradeoff between flex-
ibility and consistency. Without
consistent survey methods in place,
EPA cannot compare data submitted
by different States and jurisdictions
or determine the quality and accu-
racy of their data. Also, EPA must
use caution when comparing water
quality information submitted dur-
ing different 305(b) reporting peri-
ods because States and other juris-
dictions may modify their criteria or
survey different waterbodies from
one reporting period to the next.
    For more than 10 years, EPA
has pursued a balance between
flexibility and consistency in the
Section 305(b) process that could
generate data of known quality and
accuracy. Recent joint actions by

                                     political boundaries as they develop
                                     watershed protection  strategies.

                                         EPA recognizes that national
                                     initiatives alone cannot clean up our
                                     waters; water quality protection and
                                     restoration must happen at the local
                                     watershed level, in conjunction with
                                     State and Federal activities. Similarly,
                                     this document alone cannot provide
the detailed information needed to
manage water quality at all levels.
This document should be used
together with the individual Section
305(b) reports (see the inside back
cover for information on obtaining
Section 305(b) reports), watershed
management plans, and other local
documents to develop integrated
water quality management options.
 Background
    Integrated water quality man-
agement begins with a basic under-
standing of how water moves
through the environment, comes
into contact with  pollutants, and
transports and deposits pollutants.
The water cycle depicted in the
highlight on page 15 illustrates the
general links between the atmos-
phere, soil, surface waters, ground
waters, and plants. Additional links
between surface waters and ground
waters are described below.
              Rivers and
              Streams
              Rivers and streams
are characterized by flow. Perennial
rivers and streams flow continu-
ously, all year round. Nonperennial
rivers and streams stop flowing for
some period of time, usually due to
dry conditions or upstream with-
drawals. Many rivers and streams
originate in nonperennial head-
waters that flow only during snow-
melt or heavy showers. Nonperen-
nial streams provide critical habitats
for nonfish species, such as amphib-
ians and dragonflies, as well as safe
havens for juvenile fish to escape
from predation by larger fish. (See
note on page 25 regarding the

national estimate of total stream
miles almost doubling from 1.8
million miles in 1990 to more than
3.5 million miles in 1994.)
    The health of rivers and streams
is directly linked to habitat integrity
on shore and in adjacent wetlands.
Stream quality will deteriorate if
activities damage  shoreline (i.e.,
riparian) and wetlands vegetation,
which filter pollutants from runoff
and bind soils. Removal of
vegetation also eliminates shade
that moderates stream temperature
as well as the  land temperature that
can warm runoff entering surface
waters.  Stream temperature, in turn,
affects the availability of dissolved
oxygen in the water column for fish
and other aquatic organisms.
              Lakes,
              Reservoirs,
              and Ponds
    Lakes, reservoirs, and ponds are
 depressions that hold water for
 extended periods of time. These
 waterbodies may receive water
 carrying pollutants from rivers and
 streams, melting snow, runoff, or
 ground water discharge areas. Lakes
 may also receive pollution directly
 from the air.
    Pollutants become trapped in
 lakes, reservoirs, and ponds because
 water exits  these waterbodies at a
 slow rate. Therefore, they are espe-
 cially vulnerable to  additional inputs
 of pollutants from human activities
 in lake watersheds. Even under
 natural conditions,  sediment, nutri-
 ents, and organic materials accumu-
 late in lakes and ponds as part of a
 natural aging process called
 eutrophication. Unnatural sources of
 nutrients (such as point source dis-
 charges and agricultural  runoff)
overload lake systems and accelerate
eutrophication. Algae blooms,
depressed oxygen concentrations,
and aquatic weeds are symptoms of
cultural eutrophication from unnatu-
ral sources of nutrients.
              The Great
              Lakes
              The Great Lakes—
Superior, Michigan, Huron, Erie, and
Ontario—are the largest system of
fresh surface water on earth, by
area. They contain approximately
18% of the world's fresh water
supply. The Great Lakes basin is
currently home to  one-tenth of the
population in the United States and
one-quarter of the population of
Canada.
    Despite their large size, the
Great Lakes are sensitive to the
effects of a broad range of contami-
nants that enter the Lakes from
polluted air, ground water, surface
water, and overland runoff. Even
dilute quantities of toxic chemicals
can have adverse effects on water
quality in the Great Lakes because
many toxic chemicals persist in the
environment and concentrate in
organisms, including fish.
    Overall, scientists estimate that
atmospheric deposition contributes
35% to 50% of current annual
inputs of a variety of chemicals
entering the Great Lakes. In wet
deposition, precipitation events
(such as rain or snow) remove pol-
lutants from the atmosphere. Dry
deposition occurs when  particles
settle out of the air directly on a
 lake surface or within the extensive
 land basin draining into a lake. It is
 difficult to manage atmospheric
 sources of pollutants entering the
 Great Lakes because these pollutants

may originate in the Great Lakes
basin or hundreds of miles away.
    For Lake Superior, the largest of
the Great Lakes, available data indi-
cate that volatilization (i.e., evapora-
tion) and  other processes remove
far greater quantities of polychlori-
nated biphenyls (PCBs) than are
introduced to it from atmospheric
deposition and river inflow com-
bined. Atmospheric deposition,
nevertheless, is the largest source  of
new PCBs to the lake system and
serves to significantly retard the PCB
stripping process. Meanwhile,
contributions from the reservoir of
already contaminated sediments
remains the overwhelming source of
total PCBs to the water column and
biota.
                                                            Estuaries

                                                            Rivers meet the
                                                            oceans, Gulf of
                                              Mexico, and the Great Lakes in
                                              coastal waters called estuaries.
                                              Estuarine waters include bays and
                                              tidal rivers that serve as nursery
                                              areas for many commercial fish and
                                              most shellfish populations, including
                                              shrimp, oysters, crabs, and scallops.
                                              Most of our Nation's fish and shell-
                                              fish industry relies on productive
                                              estuarine waters and their adjacent
                                              wetlands to provide healthy habitat
                                              for some stage of fish and shellfish
                                              development. Recreational anglers
                                              also enjoy harvesting fish that
                                              reproduce or feed in estuaries, such
                                              as striped bass and flounder.
                                                  Pollutants from both  local and
                                              distant sources tend to  accumulate
                                              in estuaries. Most pollutants that
                                              enter rivers migrate toward the
                                              coast. As rivers approach  the coast,
                                              their mouths broaden and flow
                                              decreases. The low flow and fluctu-
                                              ating tides, typical of estuarine
welters, reduce flushing and trap
nutrients and pollutants in estuarine
waters. This natural trapping process
lays the foundation for rich
estuarine ecosystems but also makes
estuaries vulnerable to excessive
loads of nutrients and pollutants.
    Historic development patterns
have amplified natural trapping
functions and overloaded estuaries
on all our coasts. Historically, indus-
trial development and population
centers clustered around estuarine
bays with  access to shipping and an
adjacent waterbody for waste
disposal. Now, many coastal cities
must address contaminated sedi-
ments and develop alternative dis-
posal systems for their outdated
combined sewer systems.
                                                   Wetlands

                                                   In general, wetlands
                                                   are a transition zone
                                     between land and water where the
                                     soil is occasionally or permanently
                                     saturated with water. Wetlands are
                                     populated by plants that are spe-
                                     cially adapted to grow in standing
                                     water or saturated soils. There are
                                     many different types of wetlands,
                                     including marshes, bogs, fens,
                                     swamps, mangroves, prairie pot-
                                     holes, and bottomland hardwood
                                     forests. Wetlands may not always
                                     appear to be wet. Many wetlands
                                     dry out for extended periods of
                                     time. Other wetlands may appear
                                     dry on the surface but  be saturated
                                     beneath the surface.
                                         Saltwater wetlands fringe estuar-
                                     ies; freshwater wetlands border
                                     rivers, lakes, and the Great Lakes or
                                     occur in isolation. In general,
                                     wetlands improve water quality,
                                     provide critical habitat for a wide
                                     variety of fish and wildlife,  provide
                                     storage for flood waters, and

                                                                                 Chapter One  Introduction   7
stabilize shorelines. Wetlands filter
sediment and nutrients (from both
natural and unnatural sources) out
of the water before they enter adja-
cent waterbodies and underlying
ground water aquifers. Wetlands
also provide storage for floodwaters
and reduce the velocity of overland
runoff. Reduced velocity translates
into less damage from flood waters.
    Wetlands can be physically
destroyed by filling, draining, and
dewatering, or wetlands can be
damaged by the same pollutants
that degrade other waterbodies,
such as toxic chemicals and oxygen-
demanding substances.
              Ocean
              Shoreline
              Waters
    Our ocean shoreline waters
provide critical habitat for various
life stages of commercial fish and
shellfish (such as shrimp), provide
habitat for endangered species
(such as sea turtles), and support
popular recreational activities,
including  sport fishing and swim-
ming. Despite their vast size and
volume, oceans are vulnerable to
impacts from pollutants, especially
in nearshore waters that receive
inputs from adjoining waterbodies,
ground water seeps, and land
surfaces. Beach closures due to ele-
vated bacterial concentrations are
one of the most visible symptoms of
water quality degradation in ocean
shoreline waters resulting from
activities onshore. Wastes disposed
of offshore may also impact
nearshore waters, as was demon-
strated in the late 1980s when trash
and medical wastes disposed of at
sea washed ashore on the East
Coast. Oil spills from tankers or
offshore extraction facilities can also
generate persistent adverse impacts
on ocean shoreline waters.

             Ground Water

             Beneath the land's
             surface, water resides
in two general zones, the saturated
zone and the unsaturated zone
(Figure 1-1). The unsaturated zone
lies directly beneath the land sur-
face, where air and water fill in the
pore spaces between soil and rock
particles. Water saturates the pore
spaces in the saturated zone
beneath the unsaturated zone in
most cases. The term "ground
water" applies to water in the satu-
rated zone. Surface water replen-
ishes (or recharges) ground water
by percolating through the
unsaturated zone. Therefore, the
unsaturated zone plays an
important role in ground water
hydrology and  may act as a path-
way for ground water contamina-
tion.
    Ground water can move later-
ally and emerge at discharge sites,
such as springs  on  hillsides or seeps

 The Clean Water Act of 1972

 . . . it is the national goal
 that,  wherever attainable,
 an interim goal of-water
 quality -which provides for
 tJie protection and propaga-
 tion offish, shellfish, and
 -wildlife and provides for
 recreation in and on the
 water, be achieved by
July 1, 1983 .  . .
Water quality standards
  consist of:
• Designated beneficial uses
• Numeric criteria for
  biological chemical, and
  physical parameters
• Narrative criteria for
  biological, chemical, and
  physical parameters
• Antidegradation policy
 in the bottoms of streams, lakes,
 wetlands, and oceans. Therefore,
 ground water affects surface water
 quantity and quality because pol-
 luted ground water can contami-
 nate surface waters. Conversely,
 some surface waters, such as wet-
 lands, contain flood waters and
 replenish ground waters. Loss of
 wetlands reduces ground water
 recharge.

 The Clean Water Act

    The Clean Water Act still guides
 Federal, State, and some Tribal
 water pollution control programs
 more than 20 years after it was
 enacted by Congress. In 1972, the
 CWA launched a national  objective
 to "restore and maintain the chemi-
 cal, physical, and biological integrity
 of the Nation's waters." The Act set
 two goals to achieve this objective:

 • Eliminate the discharge of pollut-
 ants into navigable waters by 1985

 • Achieve an interim water quality
 level that protects and propagates
 fish, shellfish,  and wildlife and
 supports recreation in and on the
 water, where  attainable.

    As it became evident that the
 Nation could  not eliminate pollutant
 discharges by 1985, Congress
 amended the CWA to stress achiev-
 ing the interim water quality levels,
which came to be known as "the
fishable and swimmable goals of the
Act."
    The EPA measures  national
 progress in achieving the CWA
interim water quality levels by
summarizing attainment of State
and Tribal water quality standards.
Water quality standards consist of
 designated beneficial uses, numeric
 and narrative criteria sufficient to
 protect each use, and an antidegra-
 dation statement:

 • Designated beneficial uses are
 the desirable uses that water quality
 should support. Examples are
 drinking water supply, primary con-
 tact recreation (such as swimming),
 and aquatic life support. Each  desig-
 nated use has a unique set of water
 quality requirements or criteria that
 must be met for  the use to be real-
 ized. States, Tribes, and other juris-
 dictions may designate an individual
 waterbody for multiple beneficial
 uses.

 • Numeric water quality criteria
 establish the minimum physical,
 chemical, and biological parameters
 required to support a beneficial use.
 Physical and chemical numeric
 criteria may set maximum concen-
 trations of pollutants, acceptable
 ranges of physical parameters such
 as flow, and minimum concentra-
 tions of desirable parameters, such
 as dissolved oxygen. Numeric bio-
 logical  criteria describe the expected
 attainable community attributes and
 establish values based on measures
 such as species richness, presence or
 absence of  indicator taxa,  and  distri-
 bution  of classes of organisms.

 • Narrative water quality criteria
 define, rather than quantify, condi-
 tions and attainable goals that  must
 be maintained to support a desig-
 nated use. Narrative  biological  cri-
 teria establish a positive statement
 about aquatic community  character-
 istics expected to occur within  a
waterbody. For example, "Aquatic
 life shall be as it naturally occurs,"
or "Ambient water quality  shall be
sufficient to support life stages  of all

-------
                                                                                 Chapter One  Introduction  9
indigenous aquatic species."
Narrative criteria may also describe
conditions that are desired in a
waterbody, such as, "Waters must
be free of substances that are toxic
to humans, aquatic life, and wild-
life."

•  Antidegradation statements,
where possible, protect existing uses
and prevent waterbodies from
deteriorating even if their water
quality is better than the fishable
and swimmable goals of the Act.

    The CWA allows States, Tribes,
and other jurisdictions to set their
own standards but requires that all
beneficial uses and their criteria
comply with the goals of the Act.  At
a minimum, beneficial uses must
provide for "the protection and
propagation of fish, shellfish, and
wildlife"  and provide for "recreation
in and on the water" (i.e., the  fish-
able and swimmable goals of the
Act), where attainable. The Act pro-
hibits States and other jurisdictions
from  designating waste transport or
waste assimilation as a beneficial
use, as some States did prior to
1972.
 Survey
 Methodology
    Section 305(b) of the CWA
 requires that the States biennially
 survey their water quality for attain-
 ment of the fishable and swimmable
 goals of the Act and report the
 results to  EPA. The States, participat-
 ing Tribes, and other jurisdictions
 measure attainment of the CWA
 goals by determining  how well their
 waters support their designated
 beneficial uses. EPA encourages
States, Tribes, and other jurisdictions
to survey waterbodies for support of
the following individual beneficial
uses:

             Aquatic
             Life Support

             The waterbody pro-
vides  suitable habitat for protection
and propagation of desirable fish,
shellfish, and other aquatic
organisms.

              Fish Consumption

             The waterbody sup-

                                     or contact with the water.

                                                  Agriculture

                                                  The water quality is
                                                  suitable for irrigating
                                     fields or watering livestock.

                                         States, Tribes, and other juris-
                                     dictions may also define their own
                                     individual uses to address special
                                     concerns. For example, many Tribes
                                     and States designate their waters for
                                     the following  beneficial uses:
                                                  Ground Water
                                                  Recharge

                                                  The surface water-
                                     body plays a significant role in
                                     replenishing ground water, and
                                     surface water supply and quality are
                                     adequate to protect existing or
                                     potential uses of ground water.
                                                  Wildlife Habitat

                                                  Water quality sup-
                                                  ports the waterbody's
                                     role in providing habitat and
                                     resources for land-based wildlife as
                                     well as aquatic life.

                                        Tribes may designate their
                                     waters for special cultural and
                                     ceremonial uses:

                                                  Culture

                                                  Water quality sup-
                                                  ports the waterbody's
                                     role in Tribal culture and preserves
                                     the waterbody's religious, ceremo-
                                     nial, or subsistence significance.

                                        The States, Tribes, and  other
                                     jurisdictions assign one of five levels
                                     of use support categories to each
                                     of their waterbodies (Table  1 -1).
 If possible, the States, Tribes, and
 other jurisdictions determine the
 level of use support by comparing
 monitoring data with numeric crite-
 ria for each use designated for a
 particular waterbody. If monitoring
 data are not available, the State,
 Tribe, or other jurisdiction may
 determine the  level of use support
 with qualitative information. Valid
 qualitative information includes land
 use data, fish and game surveys,
 and predictive  model results. Moni-
 tored assessments are based on
 recent monitoring data collected
 during the past 5 years. Evaluated
 assessments are based on qualita-
 tive information or monitored infor-
 mation more than 5 years old.

 Overall Use Support

     For waterbodies with more than
 one designated use, the States,
 Tribes, and other jurisdictions
 consolidate the individual use sup-
 port information into a single overall
 use support determination:

         Good/Fully Supporting
         Overall Use - All desig-
         nated beneficial uses are
         fully supported.

         Good/Threatened Over-
         all  Use - One or more
         designated beneficial uses
         are threatened and the
 remaining uses are fully supported.

         Fair/Partially Supporting
         Overall  Use - One or
         more designated bene-
         ficial uses are partially
supported and the remaining uses
are fully supported or threatened.
These waters are considered
impaired.

         Poor/Not Supporting
         Overall Use - One or
         more designated bene-
         ficial uses are not
supported. These waters are consid-
ered impaired.
         Poor/Not Attainable -
         The State, Tribe, or other
         jurisdiction has performed
         a use-attainability analysis
and demonstrated that use support
of one or more designated bene-
ficial uses is not attainable due to
one of six biological, chemical,
physical, or economic/social condi-
tions specified  in the Code of Federal
Regulations (40 CFR Section
131.10). These conditions include
naturally high concentrations of
pollutants (such as metals); other
natural physical features that create
unsuitable aquatic life habitat (such
as inadequate  substrate, riffles, or
pools); low flows or water levels;
dams and other hydrologic modifi-
cations that permanently alter
waterbody characteristics; poor
water quality resulting from human
activities that cannot be reversed
without causing further environ-
mental degradation; and poor water
quality that cannot be improved
without imposing more stringent
controls than those required in the
CWA that would result in wide-
spread economic and social
impacts.

• Impaired Waters - The sum of
waterbodies partially supporting
uses and not supporting uses.
Total Surveyed Waters

    Most States do not assess all of
their waterbodies during the 2-year
reporting cycle required under CWA
Section 305(b). Thus, the surveyed
waters reported in Figure 1 -2 are a
subset of the Nation's total waters.
In addition, the summary informa-
tion based on surveyed waters may
not represent general conditions in
the Nation's total waters because
States, Tribes, and other jurisdictions
often focus on surveying major
perennial rivers, estuaries, and pub-
lic lakes with suspected pollution

                                     resources to areas that could pose
                                     the greatest risk. Many States,
                                     Tribes, and other jurisdictions lack
                                     the resources to collect use support
                                     information for nonperennial
                                     streams, small tributaries, and pri-
                                     vate ponds. This report does not
                                     predict the health of these
                                     unassessed waters, which include an
                                     unknown ratio of pristine waters to
                                     polluted waters.
SAMPLE
               Little River
               Little River is designated for aquatic life use
               and primary contact recreation. The State
               examines dissolved oxygen data and notes
               that 15% of the samples contain dissolved
               oxygen concentrations below the aquatic life
               use criterion of 5 parts per million (ppm).
  Bacterial indicators do not exceed the contact recreation
  criterion. Therefore, the waterbody partially supports aquatic
  life use and fully supports contact recreation use. The water-
  body partially supports overall uses based on monitored data.
SAMPLE
               Turkey Lake

               Turkey Lake is also designated for aquatic life use and
               primary contact recreation. However, the State has
               never sampled chemical and physical parameters, such
               as dissolved oxygen, in the lake. The State
               did perform a biological survey of the lake
               and noted the presence of desirable fish spe-
  cies and insect larvae. The survey also revealed a probable
  source of sewage contamination upstream. The lake
  appears to fully support aquatic life use but may only
  partially support contact recreation use due to sewage
  contamination. The waterbody partially supports overall
  uses based on evaluated information (the suspected source
  of sewage contamination).
 Pollutants That
 Degrade Water
 Quality and Sources
 of Impairment

    Where possible, States, Tribes,
 and other jurisdictions identify the
 pollutants causing water quality
 impairments and the sources of
 pollutants degrading their water-
 bodies. Causes of impairment are
 pollutants or processes that violate
 numeric or narrative use support
 criteria. Causes of impairment
 include chemical contaminants
 (such as PCBs, dioxins, and metals),
 physical parameters (such as tem-
 perature), and biological parameters
 (such as aquatic weeds) (see High-
 light on page 16).
    Sources of impairment gener-
 ate the pollutants that violate use
 support criteria (Table 1 -2). Point
 sources discharge pollutants directly
 into surface waters from a convey-
 ance. Point sources include indus-
 trial facilities, municipal sewage
 treatment plants, and combined
 sewer overflows.  Nonpoint sources
 deliver pollutants to surface waters
from diffuse origins. Nonpoint
sources include urban runoff,
agricultural runoff, and atmospheric
deposition of contaminants in air
 pollution. Habitat alterations, such
as hydromodification, dredging, and
streambank destabilization, can also
degrade water quality.

                                     States because the States identify
the causes and sources degrading
some of their impaired waters,
which are a small subset of surveyed
waters, which, in turn, are a subset
of the Nation's total waters. For
example, the States identified
sources degrading some of the
224,236 impaired river miles, which
represent 36% of the surveyed river
miles and only 6% of the Nation's
total stream miles.

The Water Cycle
    The water cycle describes how
water moves through the environ-
ment and identifies the links
between ground water, surface
water, and the atmosphere (see
figure). For convenience, discussions
of the water cycle usually begin and
end in the atmosphere. Water in
the atmosphere condenses and falls
onto the earth in the form of rain or
snow. The rain or snow can contain
contaminants from air pollution.
The rain and snow may fall directly
onto surface waters, be intercepted
by plants or structures, or fall onto
the ground. Intercepted water
evaporates directly back into the
atmosphere or drips onto the
ground.
     On the ground, rainfall and
 melting snow percolate deeper into
the ground, saturating the soil  and
 recharging ground water aquifers.
Trees and other plants take up
 water in the upper soil zone
 through their roots and return  the
 water to the atmosphere in a
 process called transpiration. Ground
 water below the root zone may
 migrate many miles and emerge
 (or discharge) into a distant surface
 water.
     When rainfall or melting snow
 saturates soils, water runs off the
 ground into surface waterbodies
 (such as lakes, streams, wetlands,
 and coastal waters). Runoff may
 dislodge soil particles and pollutants
 and carry them into surface water-
 bodies. Surface waters may evapo-
 rate back into the atmosphere,
percolate into the underlying
ground water, or flow into other
surface waters until reaching the
ocean. From the ocean, water
evaporates back into the atmos-
phere, completing the cycle.
                                                                                           HT HIGHLIGHT

                                        This highlight describes indi-
                                     vidual pollutants and processes
                                     separately. In reality, water quality
                                     usually suffers from the combined
                                     effects of several pollutants and
                                     processes. EPA encourages water
                                     quality managers and the public to
                                     use a holistic approach to managing

                                     Low Dissolved Oxygen

                                        Dissolved oxygen is a basic
                                     requirement for a healthy aquatic
                                     ecosystem. Most fish and beneficial
                                     aquatic insects "breathe" oxygen
                                     dissolved in the water column.
                                     Some fish  and aquatic organisms
                                     (such as carp and sludge worms)
                                     are adapted to low oxygen condi-

                                     (such as trout and salmon) suffer if
                                     dissolved oxygen concentrations fall
                                     below 3 to 4 mg/L (3 to 4 milli-

                                     of water, or 3 to 4 parts of oxygen
                                     per million parts of water). Larvae
                                     and juvenile fish are more sensitive
                                     and require even higher concentra-

                                    from 5 to 8 mg/L.
                                       Many fish and  other aquatic
                                     organisms  can recover from short

                                                   or less can result in "dead" water-

                                                  waters, beneficial bacteria use oxy-

replenishment from the atmosphere
and photosynthesis performed by
algae and aquatic plants. The result
is a net decline in oxygen concen-
trations in the water.
    Often, water quality managers
measure the biological oxygen
demand (or BOD) of pollution or
natural organic materials in water.
BOD is a measure of how much
oxygen is consumed by bacteria
while they decompose different
mixtures of organic  materials. Toxic
pollutants can indirectly elevate
BOD by killing algae, aquatic weeds,
or fish, which provides  an abun-
dance  of food for oxygen-consum-
ing bacteria. Oxygen depletion can
also result from chemical reactions
that do not involve  bacteria. Some
pollutants trigger chemical reactions
that place a chemical oxygen
demand (or COD) on receiving
waters.
    Other factors, such as  temper-
ature and salinity, influence the
amount of oxygen dissolved in
water. Prolonged hot weather will
depress oxygen concentrations and
may cause fish kills even in clean
waters because warm water cannot
hold as much oxygen as cold water.
Warm conditions further aggravate
oxygen depletion by stimulating
bacterial activity and respiration in
fish, which consumes oxygen.
 Removal of streamside vegetation
eliminates shade, thereby  raising
water temperatures, and accelerates
runoff of organic debris. Under such
conditions, minor additions of pollu-
tion-containing organic materials
can severely deplete oxygen.

Nutrients

    Nutrients are essential building
blocks for healthy aquatic communi-
ties, but excess nutrients (especially
nitrogen and phosphorus com-
pounds) overstimulate the growth
of aquatic weeds and algae. Exces-
sive growth of these organisms, in
turn, can clog navigable waters,
interfere with swimming and boat-
ing, outcompete native submerged
aquatic vegetation (SAV), and lead
to oxygen depletion. Oxygen
concentrations can fluctuate daily
during algae blooms, rising during
the day as algae perform photosyn-
thesis, and falling at night as algae
continue to respire, which consumes
oxygen. Beneficial bacteria also con-
sume oxygen as they decompose
the abundant organic food supply
in dying algae cells.
     Lawn and crop fertilizers, sew-
age, manure, and detergents con-
tain nitrogen and phosphorus, the
 nutrients most often responsible for
water quality degradation. Rural
 areas are vulnerable to ground
water contamination from nitrates
 (a  compound containing nitrogen)
found in fertilizer and manure.

                Very high concentrations of nitrate
                (>10 mg/L) in drinking water cause
                methemoglobinemia, or blue baby
                syndrome, an inability to fix oxygen
                in the blood.
                    Nutrients are difficult to control
                because lake and estuarine ecosys-
                tems recycle nutrients. Rather than
                leaving the ecosystem, the nutrients
                cycle among the water column,
                algae and plant tissues, and the
                bottom sediments. For example,
                algae may temporarily remove all
                the nitrogen from the water col-
                umn, but the nutrients will return to
                the water column when the algae
                die and are decomposed by bacte-
                ria. Therefore, gradual inputs of
                nutrients tend to accumulate over
                time rather than leave the system.

                Sediment and Siltation

                   In a water quality context,  sedi-
                ment usually refers to soil particles
                that enter the water column from
                eroding land. Sediment consists of
                particles of all sizes, including fine
                clay particles, silt, sand, and gravel.
                Water quality managers use the
                term "siltation" to describe the sus-
                pension and deposition of  small
                sediment particles in waterbodies.
                   Sediment and siltation  can
                severely alter aquatic communities.
                Sediment may clog and abrade fish
               gills, suffocate eggs and aquatic
               insect larvae on the bottom, and fill
               in the pore space between bottom
               cobbles where fish lay eggs. Silt and
               sediment interfere with recreational
               activities and aesthetic enjoyment at
               waterbodies by reducing water
               clarity and filling in waterbodies.
 Sediment may also carry other pol-
 lutants into waterbodies. Nutrients
 and toxic chemicals may attach to
 sediment particles on land and ride
 the particles into surface waters
 where the pollutants may settle with
 the sediment or detach and become
 soluble in the water column.
     Rain washes silt and other soil
 particles off of plowed fields, con-
 struction  sites, logging sites, urbah
 areas, and strip-mined lands into
 waterbodies. Eroding streambanks
 also deposit silt and sediment in
 waterbodies. Removal of vegetation
 on shore  can accelerate streambank
 erosion.

 Bacteria and Pathogens

    Some waterborne bacteria,
 viruses, and protozoa cause human
 illnesses that range from typhoid
 and dysentery to  minor respiratory
 and skin diseases. These organisms
 may enter waters through a  number
 of routes,  including inadequately
 treated  sewage, storm water drains,
 septic systems, runoff from livestock
 pens, and sewage dumped over-
 board from recreational boats.
 Because it is impossible to  test
 waters for every possible disease-
 causing organism, States and other
 jurisdictions usually measure indica-
 tor bacteria that are found in great
 numbers in the stomachs and intes-
 tines of  warm-blooded animals  and
 people.  The presence of indicator
 bacteria suggests that the water-
 body may be contaminated with
untreated  sewage and that other,
more dangerous, organisms may be
present. The States, Tribes, and

other jurisdictions use bacterial crite-
ria to determine if waters are safe
for recreation and shellfish harvest-
ing.

Toxic Organic Chemicals
and Metals
Toxic organic chemicals are
synthetic compounds that contain
carbon, such as PCBs, dioxins, and
DDT. These synthesized compounds
often persist and accumulate in the
environment because they do not
readily break down in natural eco-
systems. Many of these compounds
cause cancer in people and birth
defects in other predators near the
top of the food chain, such as birds
and fish.
Metals occur naturally in the
environment, but human activities
(such as industrial processes and
mining) have altered the distribution
of metals in the environment. In
most reported cases of metals
contamination, high concentrations
of metals appear in fish tissues
rather than the water column
because the metals accumulate in
greater concentrations in predators
near the top of the food chain.
r»H
pri
Acidity, the concentration of
hydrogen ions, drives many chemi-
cal reactions in living organisms.
The standard measure of acidity is
pH, and a pH value of 7 represents
a neutral condition. A low pH value
(less than 5) indicates acidic
conditions; a high pH (greater than

9) indicates alkaline conditions.
Many biological processes, such as
reproduction, cannot function in
acidic or alkaline waters. Acidic con-
ditions also aggravate toxic con-
tamination problems because sedi-
ments release toxicants in acidic
waters. Common sources of acidity
include mine drainage, runoff from
mine tailings, and atmospheric
deposition.
Habitat Modification/
Hydrologic Modification

Habitat modifications include
activities in the landscape, on shore,
and in waterbodies that alter the
physical structure of aquatic ecosys-
tems and have adverse impacts on
aquatic life. Examples of habitat
modifications include:
• Removal of streamside vegetation
that stabilizes the shoreline and
provides shade, which moderates
instream temperatures
• Excavation of cobbles from a
stream bed that provide nesting
habitat for fish

• Burying streams
• Excessive development sprawl
that alters the natural drainage pat-
terns by increasing the intensity,
magnitude, and energy of runoff
waters.
Hydrologic modifications alter
the flow of water. Examples of
hydrologic modifications include
channelization, dewatering,
damming, and dredging.

                                       Tribes throughout the United States.
                                       Over the past 7 years, approxi-
                                       mately 100 Tribes have developed
                                       or have begun developing water
                                       quality programs, including water
                                       quality criteria and standards,

                                       the Clean Water Act. This number
                                       represents close to 40% of all Tribes
                                                     in the contiguous United States that
                                                     are eligible for Section 106 grants, a
                                                     number that reflects the importance
                                                     of this effort by Tribes. Tribes are

                                                     Tribes  have special concerns about

training staff to perform monitoring.
Joint Tribal consortia, intertribal
councils, and other collaborative
efforts have been established to
examine entire watersheds. All of
these efforts reiterate the common
goal shared by communities
throughout the country to acquire
the data needed to preserve and
restore water quality for generations
to come. Tribes will continue to
make water quality a priority as they
develop  and expand their capacity
to contribute information to the
National Water Quality Inventory
Report to Congress.
    EPA's Office of Wetlands,
Oceans,  and Watersheds (OWOW),
in conjunction with the Section
305(b) Consistency Workgroup
(which includes  3 Tribal members
and 25 State members), developed
flexible guidance to assist Tribes in
reporting water quality information
for inclusion in the 1996 National
Water Quality Inventory Report to
Congress. This guidance describes a
level of reporting that may be
appropriate for most Tribes' first
305(b) reports.
     In 1995, OWOW also produced
a booklet, Knowing Our Waters:
 Tribal Reporting Under Section
305(b), to encourage all Tribes to
monitor, assess, and report on their
water quality. The goal  of Tribal
reporting is to document the status
of water quality and identify water
quality improvements needed on
Tribal lands. The 305(b) report is a
good vehicle for recommending
actions to EPA to protect Tribal
waterbodies and achieve the objec-
tives of the Clean Water Act. EPA
encourages Tribes to use the 305(b)
process as a mechanism for sharing
their ideas, concerns, and informa-
tion with State and Federal water
quality managers.

Rivers  and  Streams
    Forty-eight States, three Inter-
state River Commissions, one Terri-
tory, and the District of Columbia
(hereafter collectively referred to as
States), and six American Indian
Tribes rated river water quality in
their 1994 Section 305(b) reports
(see Appendix A, Table A-1, for
individual State and  Tribal informa-
tion). These States and Tribes sur-
veyed conditions in 615,806 miles
of rivers and streams; most of the
surveyed rivers and streams  are
perennial waterbodies that flow all
year. The surveyed rivers and
streams represent 48% of the
1.3 million miles of perennial
rivers and streams in the lower
48 States, or 17% of the esti-
mated 3.5 million miles of all
  rivers and streams in the country,
  including nonperennial streams that
  flow only during wet periods
  (Figure 2-1).
     Altogether, the  States and
  Tribes surveyed 27,075 fewer river
  miles in 1994 than  in 1992. Indi-
  vidually, most States reported that
  they surveyed more river miles in
  1994, but their increases were offset
  by a decline of 85,000 surveyed
  river miles reported by Montana,
  Mississippi, and Maryland. For 1994,
  these States reported use support

  they surveyed in direct monitoring

                                      Note:  In comparison to 1990, it appears that
                                            the States and Tribes assessed a
                                            smaller percentage of the Nation's
                                            rivers in 1994. However, in  1994,
                                            most States and Tribes included
                                            intermittent streams, canals, and
                                            ditches that were excluded  from the
                                            1990 estimates of total stream miles.
                                            As a result, the national estimate of
                                            total stream miles almost doubled
                                            from  1.8 million miles in 1990 to
                                            more than 3.5 million miles in 1994.

                                     waters. Previously, Montana and
                                     Maryland assumed that rivers of
                                     unknown quality were surveyed and
                                     in good condition. Mississippi
                                     assumed that conditions in evalu-
                                     ated rivers represented conditions in
                                     upstream tributaries.

                                     examples of the numerous modifica-
                                     tions the States made to their water

                                     summary data presented herein
                                     should not be compared with sum-
                                     mary data presented in the 1992
                                     Report to Congress.
                                        The summary information pre-
                                     sented in this chapter applies strictly
                                     to the portion of the Nation's rivers
                                     surveyed by the States and Tribes.
                                     EPA cannot make generalizations
                                     about the health of all of our
                                     Nation's rivers based on data
                                     extracted from the 305(b) reports
                                     because most States and Tribes rate
                                    their waters with information
                                    obtained from water monitoring
                                     programs designed to detect
                                    degraded waterbodies. Very few
                                    States or Tribes select water sam-
                                    pling sites with a statistical design to
                                    represent a cross section of water
                                    quality conditions in their jurisdic-
                                    tion. Instead, many States and
                                    Tribes direct their limited monitor-
                                    ing resources toward waters with
                                    suspected problems. As a result, the
                                    surveyed rivers reflect conditions of
                                    targeted waters rather than a repre-
                                    sentative sampling of all waters.
                                        In the future, increased use  of
                                    statistically based programs will
 enable EPA and the States and
 Tribes to report more comprehen-
 sively on the general health of the
 Nation's waters. Examples of statisti-
 cally based programs include prob-
 ability designs implemented by
 Delaware and Maryland, EPA's Envi-
 ronmental  Monitoring and Assess-
 ment Program (EMAP), and EPA's
 Regional Environmental Monitoring
 and Assessment Program (R-EMAP).
 EMAP is a long-term monitoring
 program with a unique approach
 that combines a probability-based
 sampling strategy with ecological
 indicators (quantifiable expressions
 of an environmental value) to assess
 the overall  condition of ecological
 resources. R-EMAP applies the con-
 cepts, methods, and approach
 developed  by EMAP to resolve spe-
 cific environmental issues of impor-
 tance to the EPA Regions and the
 States.
     National data from other Fed-
 eral agencies, such as the U.S. Geo-
 logical Survey (USGS) and the
 National Oceanic and Atmospheric
 Administration (NOAA), and private
 organizations, such as the Nature
 Conservancy, will also clarify
 national water quality trends. (See
 Chapter 13 for additional informa-
 tion  about  monitoring and
 assessment programs.)


 Overall Water Quality

    The States and Tribes rate
whether their water quality is good
enough to fully support a healthy
community of aquatic organisms
and human activities, such as swim-
ming, fishing, and drinking. The
States designate individual rivers for
specific activities, termed "individual
designated  uses." EPA and the

-------
                                                                            Chapter Two Rivers and Streams   27
States use the following terminology
to rate their water quality:

• Good/Fully Supporting: Good
water quality supports a diverse
community of fish, plants, and
aquatic insects,  as well  as the array
of human activities assigned to a
river by the State.

• Good/Threatened:  Good water
quality currently supports aquatic
life and human activities in and on
the river, but changes in factors
such as land use threaten water
quality, or data indicate a trend of
increasing pollution in the river.

• Fair/Partially Supporting:  Fair
water quality supports  aquatic
communities with fewer species of
fish, plants, and aquatic insects,
and/or occasional pollution inter-
feres with human activities. For
example,  runoff during severe thun-
derstorms may temporarily elevate
fecal coliform bacteria densities and
indicate that swimming is not safe
immediately following  storms.

• Poor/Not Supporting:  Poor
water quality does not support a
healthy aquatic community and/or
prevents some  human  activities on
the river.  For example, persistent
PCB contamination in river sedi-
ments (originating from discontin-
ued industrial discharges)  may con-
taminate fish and make the fish
inedible for years.

•  Poor/Not Attainable: The State
has performed  a use-attainability
analysis and demonstrated that use
support of one or more designated
beneficial uses  is not attainable due
to one of six specific biological,
chemical, physical, or economic/
social conditions (see Chapter 1 for
additional information).

    Most States and Tribes rate how
well a river supports individual uses
(such as swimming arid aquatic life
habitat) and then consolidate indi-
vidual use ratings into a general
water quality rating termed "overall
use support." A river receives a poor
overall rating if water quality
consistently fails to support any one
human activity or a healthy aquatic
community (see Chapter 1 for a
complete discussion of use support).
    Forty-three States, six Tribes,
three Interstate Commissions, Puerto
Rico, and the District of Columbia
reported overall use support status
for rivers and streams in their 1994
Section 305(b) reports (see Appen-
dix A, Table A-2, for  individual State
and Tribal information). Another five
States reported individual use sup-
port status but did not report over-
all use support status. In  such cases,
EPA used aquatic life use support
status to represent overall water
quality conditions in  the  State's
rivers and streams.
    Altogether, 64% of the 615,806
surveyed river miles have good
water quality. Of these waters, 57%
fully support designated  uses and
7% have good water quality that
fully supports uses but is threatened
and might deteriorate if we fail to
manage potential sources of pollu-
tion (Figure 2-2).
     Some form of pollution or
habitat degradation prevents the
remaining 36% of the surveyed river
miles from fully supporting a
healthy aquatic community or
human activities all year  round.
Twenty-two percent of the surveyed
river miles have fair water quality
that partially supports designated

uses. Most of the time, these waters
provide adequate habitat for aquatic
organisms and support human
activities,  but periodic pollution
interferes  with these activities and/or
stresses aquatic life. Fourteen per-
cent of the surveyed river miles
suffer from poor water quality that
consistently stresses aquatic life and/
or prevents people from using the
river for activities such as swimming
and fishing.


Individual  Use
Support

    Individual use support informa-
tion provides additional detail about
water quality problems in our
Nation's surface waters. The States
are responsible for designating their
rivers and  streams for State-specific
uses, but EPA requests that the
States rate how well their rivers

 support six standard uses so that
 EPA can summarize the State data.

 •  Aquatic life support - Is water
 quality good enough to support a
 balanced community of aquatic
 organisms, including fish, plants,
 insects, and algae?

 •  Fish consumption - Can people
 eat fish caught in the river or
 stream?

 •  Primary contact recreation
 (swimming) - Can  people make
 full body contact with  the water
 without risking their health?

 •  Secondary contact recreation -
 Is there a risk to public health from
 recreational activities on the water,
 such as boating, that expose the
 public to minor contact with the
 water?

 •  Drinking water supply - Can the
 river or stream  provide a safe water
 supply with standard treatment?

 • Agricultural  uses - Can the water
 be used for irrigating fields and
 watering livestock?

    Only eight States did not report
 individual use support status of  their
 rivers and streams (see Appendix A,
 Table A-3, for individual State and
 Tribal information).  The reporting
 States  and Tribes  surveyed the sta-
 tus  of aquatic life and swimming
 uses most frequently and identified
 more impacts on  aquatic life and
 swimming uses than on the other
 individual uses (Figure 2-3). These
 States and Tribes  reported that fair
 or poor water quality impacts
 aquatic life in 161,367 stream miles
 (31 % of the 527,269 miles surveyed
for aquatic life support). Fair or poor
water quality conditions also impair

swimming activities in 92,058 miles
(23% of the 394,528 miles surveyed
for swimming use support).
    Many States and Tribes did not
rate fish consumption use support
because they have not codified fish
consumption as a use in their stan-
dards. Some of these States consider
fishing use as a component of
aquatic life use-rivers and streams
that provide a  healthy habitat for
fish support fishing activities even
though anglers may not be able to
eat their catch in these  States. EPA
encourages the States to designate
fish consumption as a use in their
waterbpdies to promote consistency
in future reporting.


Water Quality
Problems Identified
in Rivers  and Streams

    Figures 2-4 and 2-5 identify the
pollutants and sources of  pollutants
that impair (i.e., prevent from fully
supporting designated uses) the
most river miles, as reported by  the
States and Tribes. The two figures
are based on the same  data (con-
tained in Appendix A, Tables A-4
and A-5), but each figure provides a
different perspective on the extent
of impairment attributed to indi-
vidual pollutants and sources.  Figure
2-4 compares  the impacts of the
leading pollutants and sources in all
surveyed rivers. Figure  2-5 presents
the relative impact of the leading
pollutants and sources in  impaired
rivers, a subset of surveyed rivers
with identified water quality
problems.
    The following sections describe
the leading pollutants and sources
of impairment identified in rivers. It
is important to note that  the
information about pollutants and
sources is incomplete because the
States cannot identify the pollutant
or source of pollutants responsible
for every impaired river segment.
In some cases, a State may recog-
nize that water quality does not
fully support a designated use, but
the State may not have adequate
data to document that a specific

Siltation is one of the leading pollution problems in the Nation's rivers
and streams. Over the long term, unchecked siltation can alter habitat
with profound adverse effects on aquatic life. In the short term, silt
can kill fish directly, destroy spawning beds, and increase water turbid-
ity resulting in depressed photosynthetic rates.
on aquatic life and human activities
(i.e., the number of river miles im-
paired by  each pollutant or process)
rather than actual pollutant loads in
rivers and  streams. This approach
targets the pollutants and processes
causing the most harm to aquatic
life and public use  of our waters,
rather than the most abundant pol-
lutants in our rivers and streams.
    The States and Tribes report
that bacteria pollute 76,397 river
miles (which equals 12% of the
surveyed river  miles). Bacteria pro-
vide evidence of possible fecal  con-
tamination that may cause illness if
the public ingests the water. States
use bacterial indicators to determine
if rivers are safe for swimming arid
drinking. Bacteria commonly enter
surface waters  in inadequately
treated sewage, fecal material from
wildlife, and runoff from pastures,
feedlots, and urban areas.
    Siltation, composed of tiny soil
particles, remains one of the most
widespread pollutants impacting
rivers and  streams (Figure 2-6). The
States and Tribes reported that silt-
ation impairs 75,792 river miles
(which equals  12% of the surveyed
river miles). Siltation alters aquatic
habitat and suffocates fish eggs and
bottom-dwelling organisms. Aquatic
insects live in the spaces between
cobbles, but their habitat is
destroyed  when  silt fills in these
spaces. The loss of aquatic insects
adversely.impacts fish and other
wildlife that eat these insects. Exces-
sive siltation can  also interfere with
drinking water treatment processes
and  recreational  use of a river.
Sources of siltation  include agricul-
ture, urban runoff,  construction, and
forestry.
    In addition to siltation and bac-
teria, the States and Tribes also

                                                                            Chapter Two  Rivers and Streams   33
reported that nutrients, oxygen-
depleting substances, metals, and
habitat alterations impact more
miles of rivers and streams than
other pollutants and processes.
Often, several pollutants and
processes impact a single river seg-
ment. For example, a process, such
as removal of shoreline vegetation,
may accelerate erosion  of sediment
and nutrients into a stream. In such
cases, the States and Tribes count a
single mile of river under each pol-
lutant and process category that
impacts the river mile. Therefore,
the river miles impaired by each
pollutant or process do not add up
to 100%.
    Most States and Tribes also rate
pollutants and processes as major or
moderate/minor contributors to
impairment. A major pollutant or
process  is solely responsible for an
impact or predominates over other
pollutants and processes. A moder-
ate/minor pollutant or process is
one of multiple  pollutants and pro-
cesses that degrade aquatic life or
interfere with human use of a river.
    Currently, EPA ranks pollutants
and processes by the geographic
extent of their impacts  (i.e., the
number of miles impaired by each
pollutant or process). However, less
abundant pollutants or processes
may have more severe  impacts^on
short stream reaches. For example,
a toxic chemical spill can eliminate
aquatic life in a  short stream while
widely distributed bacteria do not
affect aquatic life but occasionally
indicate a potential human health
hazard from swimming. The indi-
vidual State and Tribal 305(b)
reports provide  more detailed infor-
mation about the severity of pollu-
tion in specific locations.
Sources of Pollutants
Impacting  Rivers
and Streams

    Fifty-two States and Tribes
reported sources of pollution related
to human activities that impact
some of their rivers and streams (see
Appendix A, Table A-5, for indi-
vidual State and Tribal information).
These States and Tribes reported
that agriculture is the most wide-
spread source of pollution in the
Nation's surveyed rivers. Agriculture
generates pollutants that degrade
aquatic life or interfere with public
use of 134,557 river miles (which
equals 22% of the surveyed river
miles) in 49 States and Tribes
(Figures 2-4 and 2-5).
    Twenty-one States reported the
size of rivers impacted by specific
types of agricultural activities:

•  Nonirrigated Crop Production -
crop production that relies on rain
as the sole  source of water.

•  Irrigated Crop Production - crop
production that uses irrigation
systems to supplement rainwater.

•  Rangeland - land grazed by ani-
mals that is seldom enhanced by
the application  of fertilizers or pesti-
cides, although land managers
sometimes  modify plant species to  a
limited extent.

•  Pastureland - land upon which a
crop (sjuch  as alfalfa)  is raised to
feed animals, either by grazing the
animals among the crops or har-
vesting the crops. Pastureland is
actively managed to encourage
selected plant species to grow, and
fertilizers or pesticides may be
applied  more often on pastureland
than rangeland.

•  Feedlots are generally facilities
where animals are fattened. By
EPA's definition, feedlots are large
sites where many animals are
confined at high densities.

•  Animal Holding Areas - facilities
for confining animals briefly before
slaughter. By EPA's definition,
animal holding areas confine fewer
animals than feedlots.

     Nonirrigated crop production
leads the list of agricultural activities
impacting rivers and streams,
followed by irrigated crop produc-
tion, rangeland, feedlots, pasture-
land, and animal holding areas (Fig-
ure 2-7). Runoff from irrigated and
nonirrigated cropland may intro-
duce commercial fertilizers (that
contain nitrogen and phosphorus),
pesticides, and soil particles into
rivers and streams. Manure applied
to cropland  as a fertilizer may also
wash off of irrigated and nonirri-
gated fields and prevent rivers and
streams from fully supporting desig-
nated uses.
    Animal waste runoff from feed-
lots and animal holding areas can
introduce pathogens, nutrients  (in-
cluding phosphorus  and nitrogen),
and organic material to nearby
rivers and streams. Rangeland may
generate both soil  erosion and
animal waste runoff. Pastureland
usually has good ground cover that
protects the soil from eroding, but
pastureland can become a source of
animal waste runoff  if animals .graze
on impermeable frozen pastureland
during winter.
    The States and Tribes  also
report that municipal sewage treat-
ment plants pollute 37,443 river
miles (6% of the surveyed river
miles), hydrologic modifications and
habitat alterations degrade 37,080
river miles (6% of the surveyed river
miles), urban runoff and storm sew-
ers pollute 26,862 river miles (4% of
the surveyed river miles), resource
extraction pollutes 24,059 river
miles (4% of the surveyed river
miles), and industrial discharges
pollute 16,348 river miles (3% of
the surveyed river miles).
    The  States and Tribes also
report that "natural" sources impair
many miles of rivers and streams in
the absence of human activities.
"Natural" sources include soils with
natural deposits of arsenic or salts
that leach into waterbodies, water-
fowl (a source of nutrients), and
low-flow conditions and elevated
water temperatures caused by
drought. The total size of rivers
impaired by "natural" sources is
probably exaggerated because some
States may automatically attribute.
water quality impairments to "natu-
ral" sources if the State cannot iden-
tify a human activity responsible for
a water quality problem.
    Other sources, such  as mining
and forestry activities, can play a
more significant role in degrading
water quality at a regional or local
level than at the national level. For
example, resource extraction (in-
cluding acid mine drainage) contrib-
utes to the degradation of 39% of
the impaired river miles in the coal
belt States of Kentucky, Maryland,
Ohio, Pennsylvania, and  West Vir-
ginia. These States report that
resource extraction impairs about
7,590 miles of rivers and streams.
Yet, at the national level, resource
extraction contributes to the degra-
dation of only 11 % of all the
impaired river miles in the Nation.
At the local level, streams impacted
by acid mine drainage are devoid of
fish and other aquatic life due to
low pH levels and the smothering
effects of iron and other metals

deposited on stream beds. The pri-
mary sources of acid mine drainage
are abandoned coal refuse disposal
sites  and surface and underground
mines.
    In the Pacific Northwest States
of Oregon and Washington, States
identify forestry activities as respon-
sible for almost half (46%) of the
impaired river miles, but, at the
national level, States report that
forestry activities contribute to the
degradation of only 9% of the
Nation's total impaired river miles.
Forestry activities include harvesting
timber, constructing logging roads,
and  stand maintenance. California,
Florida, Montana, and Wisconsin
also  report that forestry activities
degrade over 1,000 miles of streams
in each State.
    Many States reported declines
in pollution from sewage treatment
plants and industrial discharges
since enactment of the Clean Water
Act in 1972.  The States attributed
improvements in water quality con-
ditions to sewage treatment plant
construction  and upgrades and
permit controls on industrial
discharges. Despite the improve-
ments, municipal sewage treatment
plants remain the second most
common source of pollution in riv-
ers because population growth in-
creases the burden on  our  munici-
pal facilities.
     Several States reported that they
detected more subtle impacts from
nonpoint sources,  hydrologic modi-
fications, and habitat alterations as
they reduced conspicuous pollution
from point sources. Hydrologic
modifications and  habitat alterations
are a growing concern to the States.
Hydrologic modifications include
activities that alter the  flow of water
in a stream, such as channelization,
dewatering, and damming of
streams. Habitat alterations include
removal of streamside vegetation
that protects the stream from high
temperatures and scouring of
stream bottoms. Additional gains in
water quality conditions will be
more subtle and require innovative
management strategies that go
beyond point source controls.

                                    municipal or industrial point sources
                                    that discharge to nontidal waters.
                                    Nonpoint sources, including agricul-
                                    ture and urbanization activities, have

                                    streams. Delaware has the capacity
                                    to produce over 250 million chick-

                                                  streams throughout Delaware. The
                                                  data were intended for use in the
                                                  305(b) report and to support the

using aquatic macroinvertebrates,
and habitat quality. This information
will be used to evaluate habitat
degradation as a biological stressor
in nontidal streams and to assess
the effect of nonpoint source pollu-
tion on stream ecological health.

Sampling Design
The probability-based statistical
sampling design developed by
EMAP-Estuaries was modified for
nontidal streams and used for these
assessments. This design allowed for
the assessment of conditions over
larger geographic areas by sampling
a set of randomly selected sites.
The number of sites selected
was based on the areal extent of
the length of river and stream miles
in each of 35 subbasins. The State
took samples from a list of 3,31 1
randomly selected road crossings
identified with a geographic infor-
mation system (CIS).
The distance between road
crossings in Delaware averages 1 .1
miles. Assessments were made 1 00
to 150 meters (approximately 330-
500 feet) upstream of the road
crossing to ensure that the results
were minimally affected by the
cultural activities near the road.


Using road crossings as sample
sites in Delaware is believed to be
an acceptable approach because the
road crossings occur frequently and
are fairly evenly distributed, so they
are representative of the nontidal
streams; the conditions just up-
stream from Delaware's small coun-
try roads (as opposed to major in-
terstate roads) are not significantly
different from those between roads;
and the stratification using 35
subbasins overcomes any patchiness
in distribution. The statistical cer-
tainty of this approach is being fur-
ther investigated by funding from
EMAP-Surface Waters (SW) to com-
pare the statistical validity of the
road-crossing design with the stan-
dard EMAP-SW statistical sampling
design.
The study design enabled the
data collected from these sites to be
extrapolated with confidence to the
entire State. The results from the
1 89 sampling sites represent a data-
base of sufficient size and statistical
certainty to provide a comprehen-
sive assessment of the biological
and habitat conditions of nontidal
streams throughout the State and in
individual counties.

                 Biological Monitoring

                    Chemical monitoring is particu-
                 larly complex and expensive when
                 applied to diffuse and intermittent
                 pollution sources, and criteria do
                 not exist for such major non point
                 source pollutants as sediment and
                 nutrients. Biological monitoring may
                 provide, therefore, a cost-effective
                 monitoring tool for identifying
                 nonpoint source problems and
                 tracking the progress of control
                 programs.
                    Measurements associated with
                 the aquatic macroinvertebrate com-
                 munity were  used as the basis for
                 determining the biological quality of
                 the nontidal streams. There is con-
                 siderable variability in the commu-
                 nity of organisms found in the
                 aquatic environment. This variability
                 must be accounted for in order to
                 detect differences among sites and
                 among time periods. In this study,
                 to minimize temporal variability,
                 data were collected only during the
                 fall of 2 years. Site variability was
                 further reduced by defining groups
                 of waterbodies with such similar
                 characteristics as salinity, depth,
                 width, and ecoregion. In Delaware
                 nontidal streams, this categorization
                 resulted in two  distinct ecoregions:
                 the Piedmont Ecoregion, character-
                 ized by gently rolling terrain, and
                 the Coastal Plain Ecoregion, charac-
                 terized by flat terrain. Biological
monitoring was conducted solely in
the Coastal Plain Ecoregion.
    Standardization of collection
and sample processing  methods is
also important to minimize biologi-
cal and habitat data variability. The
Mid Atlantic-Coastal Stream
Workgroup, consisting of biologists
from four States and two EPA Re-
gions, developed and tested stan-
dard methods for collecting data.
Delaware used the methods devel-
oped by this workgroup.

Habitat Measurements

    Measurements to define the
quality of the physical habitat were
used to evaluate the relationship
between habitat and biology in
both ecoregions. The habitat
parameters used to score the
habitat quality of each site are as
follows:

Northern Piedmont Ecoregion
 • Channel modification
 • Instream habitat
 • Bank stability
 • Bank vegetative type
 • Shading
 • Riparian zone width
 • Velocity or depth ratio
 • Sediment deposition
 • Embeddedness (the  percent of
   a rock "stuck"  in the substrate)
 • Riffle quality
 • Riffle quantity

assessment of the condition of the
aquatic resources in the Mid-Atlan-
tic Highlands, their associated
watersheds, and the factors that
affect them. The protection and
sustainability of these valuable natu-
ral resources can be enhanced
through cooperation among the
Federal, State, and local agencies
and citizens groups involved in
managing the area's ecosystems.
    Field studies began during
1993. This was the first step toward
building a joint monitoring and
assessment effort that will ultimately
be used to characterize the ecologi-
cal condition of the Highlands. The
field efforts in MAHA are an integra-
tion of the base EMAP-Surface
Waters stream pilot, the Region 3
R-EMAP project (biological criteria in
streams of the Ridge and Valley
region), and the TIME project
(assessment of streams sensitive to
acidic deposition in response to the
Clean Air Act Amendments).

First Survey

    During the Spring of 1993, field
crews from  Pennsylvania, Maryland,
Virginia, West Virginia, EPA Region
3, EPA's ORD, and the U.S. Fish and
Wildlife Service visited 256 stream
locations across the four-state area.
Using common protocols, they
sampled these sites for fish, benthic
invertebrates, attached algae,
physical habitat, riparian habitat,
and water chemistry. Additionally,
information from satellite images
and aerial photography were col-
lected for the watersheds sampled.
Of these sites, 41 had been specifi-
cally selected as being representa-
tive of either minimally disturbed
sites or sites known to be highly
impacted. The remainder of the
sites had been selected using a
statistical process,' similar to election

of stream. Acidic deposition appears
to account for approximately 8,000
km  (about 4,971 miles) of impacted
streams in the Appalachian Plateau.
Within this ecoregion, approxi-
mately 21,000 km  (13,049 miles)  of
the small streams snowed  little or
no chemical impact. The stream
benthic community shows a
response to these impacts, with the
response being most severe in
streams showing impacts from acid
mine drainage (Figure 3).
Riparian Condition

    Historically, alteration to the
riparian system has not been of
concern in water quality studies. But
as our concern spread to encom-
pass the protection of aquatic life, it
became apparent that alterations to
other facets of the riverine system,
besides the water itself, could sig-
nificantly impact the system. Alter-
ations to the strip of land bordering
the stream, the riparian corridor,
have been shown to have poten-
tially important implications to
aquatic life. This riparian vegetation

 Biotic Integrity

     The presence of healthy,
 diverse, and sustainable biological
 communities in streams reflects a
 strong  biotic integrity. The State
 and Regional biologists continue to
 evaluate the best indicators of biotic
 integrity and establish biological
 criteria  based on these indicators.
 Much was learned, however, during
 this first survey about the region's
 biological stream resources. In the
 smallest streams (first-order), 21% of
 the stream length (18,900 km or
 11,744 miles) contained  no fish
 (Figure  5). It is not known at
 present whether the absence of fish
 is due to natural causes or to
 anthropogenic alterations. However,
 the first-order streams contain as
 much stream length (26,000 km or
 16,156  miles) with game fish as the
 second- and third-order streams
 combined (-25,000 km or 15,535
 miles). Clearly this very small stream
 resource should be an important
 part of  any management efforts to
 sustain  sport fish. When this same
 information about fish presence is
 analyzed by ecoregion, the Ridge,
Valley, and Western Allegheny
ecoregions show significant portions
of the stream resource with no fish
present-39%, 18%, and 26%,
respectively. It is uncertain whether
the lack of fish is a natural condition
or results from disturbances to the
ecosystem.

    The Mid-Atlantic Highlands
provide habitat for one of the most
diverse fish communities in the
country. Thus the introduction of
exotic species, intentional or acci-
dental, presents a significant threat
to native fishes. Results from the first
year of the* MAHA survey provide an
initial estimate of the extent of non-
native fish in the streams of the
region.  Overall, approximately 12%
of the stream length in the  mid-
Atlantic contains nonnative  (exotic)
fish species. This is a result of  both
intentional introductions by fish
stocking programs and accidental
releases or invasions by nonnative
fishes. The presence of exotic
species  is greatest in the third-order
streams where approximately  49%
of the stream length contains exotic
fish species. In contrast, only 2% of
the first-order stream length appears
to contain nonnative fish species*
    Future analyses of the MAHA
data will refine the  estimates pro-
vided here as well as present addi-
tional information on the condition
and related causes of impacts to the
stream  resource of the Mid-Atlantic
Highlands.

   Forty-four States, Puerto Rico,
and the District of Columbia (here-
after collectively referred to as
States), and two Tribes rated lake
water quality in their 1994 Section
3Q5(b) reports (see Appendix B,
Table B-1, for individual State and
Tribal data). These States and Tribes
surveyed over 17.1 million acres of
lakes, reservoirs, and ponds, which
equals 42% of the 40.8 million
acres of lakes in the Nation (Figure
3-1). The States and Tribes based
66% of their survey on monitored
data and evaluated 18% of the
surveyed lake acres with qualitative
information (including best profes-
sional judgment by water quality
managers). The States and
governments did not specify
whether 16% of the surveyed lake
acres were monitored or evaluated.
   The number of surveyed lake
acres declined between 1992 and
1994 because several States chose
not to use their fish tissue data to
help determine overall use support.
Some of these States, such as Min-
nesota, have established massive

                                    to  the portion of the  Nation's lakes
                                    surveyed by the States and Tribes.
 EPA cannot make generalizations
 about the health of all of our
 Nation's lakes based on data
 extracted from the 305(b) reports
 because most States and Tribes rate
 their waters with information
 obtained from water monitoring
 programs designed to detect
 degraded waterbodies. Very few
 States or Tribes randomly select
 water sampling sites to represent a
 cross section of water quality condi-
 tions in  their jurisdiction. Instead,
 many States and Tribes direct their
 limited monitoring resources toward
 waters with suspected  problems. As
 a result, the surveyed lakes probably
 contain  a higher percentage of pol-
 luted waters than all of the Nation's
 lakes.


 General Water Quality

     The States and Tribes  rate
 whether their  water quality is good
 enough  to fully support a  healthy
 community of aquatic organisms
 and human activities, such as swim-
 ming,  fishing,  and drinking water
 use. The States and Tribes designate
 individual lakes for specific activities,
 termed "individual designated
 uses."  EPA and the States use the
 following terminology to rate their
 water quality:

 • Good/Fully Supporting: Good
 water quality supports a diverse
 community of fish, plants,  and
 aquatic insects, as well as the array
 of human activities assigned to a
 lake  by the State.

•  Good/Threatened:  Good water
quality currently supports aquatic
life and human activities in and on
the lake,  but changes in such factors

as land use threaten water quality,
or data indicate a trend of increas-
ing  pollution in the lake.

• Fair/Partially Supporting:  Fair
water quality supports aquatic com-
munities with fewer species of fish,
plants, and aquatic insects, and/or
occasional pollution interferes with
human activities. For example,  run-
off during severe thunderstorms
may temporarily elevate fecal
coliform bacteria densities and indi-
cate that swimming is not safe
immediately following summer
storms.

•  Poor/Not  Supporting: Poor
water quality does not support a
healthy aquatic community and/or
prevents some human activities on
the lake. For example, lake waters
may be devoid of fish for more than
a month each summer because
excessive nutrients from runoff
initiate algal blooms that deplete
oxygen concentrations.

 •  Poor/Not Attainable:  The State
 has performed a use-attainability
 analysis and demonstrated that use
 support of one or more designated
 beneficial uses is not attainable due
 to one of six  specific biological,
 chemical,  physical, or economic/
 social conditions (see Chapter 1  for
 additional information).

     Most States and Tribes rate how
 well a lake supports individual uses
 (such as swimming and aquatic life
 habitat) and then consolidate indi-
 vidual use ratings into an overall
 water quality rating. A lake receives
  a poor overall rating if water quality
  consistently fails to support any one
  human activity or a healthy aquatic
  community (see Chapter 1 for a
complete discussion of use sup-
port).
    Forty-one States, two Tribes,
Puerto Rico, and the District of
Columbia reported overall use sup-
port status for lakes in their 1994
Section 305(b) reports (see Appen-
dix B, Table B-2, for individual
State and Tribal information).
Another three States reported indi-
vidual  use support status but did
not report overall use support sta-
tus. In such cases, EPA used aquatic
life use support status to represent
general water quality conditions in
the State's lakes.
    The States and Tribes reported
that 63% of their surveyed 17.1
million lake acres have good water
quality (Figure 3-2). Waters with
good quality include 50% of the
surveyed lake acres fully supporting
uses and  13% of the surveyed lake
acres that are threatened and
 might deteriorate if we  fail to man-
 age potential sources of pollution.

                                    nated uses. Most of the time, these
                                    waters provide adequate habitat for
                                    aquatic organisms and support
                                    human activities, but periodic pollu-
                                    tion interferes with  these activities

                                    but EPA requests that the States  and
                                    Tribes rate how well their lakes sup-
                                    port six standard uses so that EPA
                                    can summarize the State and Tribal
                                    data. The  standard uses consist of
                                    aquatic life support,  fish consump-
                                    tion, primary contact recreation
                                    (such as swimming and diving),
                                    secondary contact recreation (such
                                    as boating), drinking water supply,
                                   and agricultural use (see Chapter 1
                                   for a description  of each individual
                                   use).
                                      Forty-one States, one Tribe,
                                   Puerto Rico, and  the District of
                                   Columbia reported individual use
                                   support status of their lakes, reser-
                                   voirs, and ponds  (see Appendix B,
                                   Table B-3,  for individual State and
  Tribal information). The reporting
  States and Tribes rated aquatic life
  use and swimming use in more
  lakes and.identified more impacts
  on aquatic life use and swimming
  use than the other individual uses
  (Figure 3-3). These States and gov-
  ernments reported that fair or poor
  water quality impacts aquatic life in
  over 4.4 million lake acres (31% of
  the 14.5 million acres surveyed for
  aquatic life support), and swimming
  criteria violations impact 2.9 million
  lake acres (19% of the 14.8 million
  acres surveyed for swimming use
  support).
      Many States and Tribes did not
  rate fish consumption use support
  because they have not codified fish
  consumption as a use in their stan-
  dards. Some of these States consider
  fishing use as a component of
  aquatic life use-lakes that provide a
  healthy habitat for fish support fish-
  ing activities even though anglers
  may not be able to eat their catch
  in these States. EPA encourages the
  States to designate fish consump-
  tion as a use in their waterbodies to
%  promote consistency in future
  reporting.


 Water Quality
  Problems Identified
 in Lakes,  Reservoirs,
 and  Ponds

     Figures 3-4 and 3-5 identify the
 pollutants and sources of pollutants
 that impair (i.e., prevent from fully
 supporting designated uses) the
 most acres of  lakes, as reported by
 the States. The two figures are
 based on the same data (contained
 in Appendix B, Tables B-4  and B-5),
 but each figure provides a different

-------
                                                                   Chapter Three  Lakes, Reservoirs, and Ponds   51
perspective on the extent of im-
pairment attributed to individual
pollutants and sources. Figure 3-4
shows the relative impact of the
leading pollutants and sources in
surveyed lakes. Figure 3-5 presents
the relative impact of the leading
pollutants and sources in lakes with
identified problems (i.e., impaired
lakes), a subset of surveyed lakes.
    The following sections describe
the leading pollutants and sources
of impairment identified in lakes. It
is important to note that the infor-
mation about pollutants and
sources is incomplete because the
States cannot identify the pollutant
or source of pollutants impairing
every impaired lake. In some cases,
a State may recognize that water
quality does not fully support a
designated use, but the State may
not have adequate data to docu-
ment that a specific pollutant or
process is responsible for the im-
pairment. Sources are even more
difficult to identify than  pollutants
and processes.

Pollutants  Impacting
Lakes, Reservoirs,
and Ponds

    Forty-one States, the District of
Columbia, and Puerto Rico
reported the number of lake acres
impacted by individual pollutants
and processes, such as invasions by
noxious aquatic plants (see Appen-
dix B, Table B-4, for individual
State and Tribal information). EPA
measures the impact of each  pol-
lutant or process by summing the
total lake acres impaired (i.e., not
fully supporting designated uses)
by each pollutant or process. EPA
ranks the pollutants and processes
by the extent of their impacts on
aquatic life and human activities
rather than actual pollutant loads in
lakes. This approach targets the
pollutants and processes causing
the most harm to aquatic life and
public use of our waters, rather
than the most abundant pollutants
in our lakes, reservoirs, and ponds.

                                      and 3-5). The States and Puerto
                                      Rico reported that extra nutrients
                                      pollute 2.8 million lake acres (which
                                      equals 17% of the surveyed lake

metals pollute 1.4 million acres
(which equals 8% of the surveyed
lake acres).
    Metals declined from the most
widespread pollutant impairing lakes
in the 1992 305(b) reporting cycle
to the fourth  leading pollutant
impairing,lakes in 1994. The decline
is due to changes in State reporting
and assessment methods  rather
than a measured decrease in metals
contamination.  In 1994, several
States chose to  no longer assess
overall use support with fish con-
tamination data alone. Much of that
data consisted of measurements of
metals in fish tissue. As a  result of
excluding these fish tissue data, the
national estimate of lake acres
impaired by metals fell  by over
2 million acres in 1994.
    Often, several pollutants and
processes impact a single lake. For
example, a process, such as removal
of shoreline vegetation, may
accelerate erosion of sediment and
nutrients into a lake. In such cases,
the States and Tribes count a  single
lake acre under each pollutant and
process category that impacts the
lake acre. Therefore, the lake acres
impaired by each pollutant  and
process do not  add up to 100%.
    Most States and Tribes  also rate
pollutants and processes as  major or
moderate/minor contributors to
impairment. A major pollutant or
process is solely responsible for an
impact or predominates over other
pollutants and processes. A moder-
ate/minor pollutant or process is
one of multiple pollutants and
processes that degrade aquatic life
or interfere with human use of a
lake. The States report that nutrients
are the most widespread major
cause of impairment in lakes.
    Currently, EPA ranks pollutants
and processes by the geographic
extent of their impacts (i.e., the
number of lake acres impaired by
each pollutant or process). How-
ever, less abundant pollutants or
processes may have more severe
impacts than the leading pollutants
listed  above. For example, extreme
acidity (also  known as low pH) can
eliminate fish in isolated lakes, but
acid impacts on lakes are concen-
trated in northeastern lakes and
mining States and are not wide-
spread across the country as a
whole. The individual State 305(b)
reports provide more detailed
information about the severity of
pollution in specific locations.

Sources of Pollutants
Impacting Lakes,
Reservoirs, and Ponds

    Forty-two States and Puerto
Rico reported sources of pollution
related to human  activities that
impact some of their lakes,  reser-
voirs,  and ponds (see Appendix B,
Table B-5, for individual State infor-
mation). These States and  Puerto,
Rico reported that agriculture is the
most  widespread source of pollution
in the Nation's surveyed lakes (Fig-
ures 3-4 and 3-5). Agriculture gen-
erates pollutants that degrade
aquatic  life or interfere with public
use of 3.3 million lake acres (which
equals 20%  of the surveyed lake
acres).
    The States and Puerto Rico also
reported that municipal sewage
treatment plants pollute 1.3 million
lake acres (7% of the surveyed lake
acres), urban runoff and storm sew-
ers pollute 1.2 million lake acres
(7% of the surveyed lake acres),

                                      plants may include nutrients and
ammonia, as well as oxygen-
depleting wastes and chemicals
from industrial facilities that
discharge into the municipal plarit.
    The States and Puerto Rico
listed numerous sources that impact
several hundred thousand lake
acres, including land disposal of
wastes, construction, flow regula-
tion, highway maintenance and
runoff, contaminated sediments,
atmospheric deposition of pollut-
ants, and onsite wastewater systems
(including septic tanks).

Tidal  Estuaries and
Ocean  Shoreline  Waters
    Rivers meet the oceans, Gulf of
Mexico, and the Great Lakes in
coastal waters called estuaries. This
chapter describes conditions in tidal
estuaries, where tides mix fresh
water from rivers  with saline water
from the oceans and the Gulf of
Mexico. Fresh water estuaries
around the Great Lakes are dis-
cussed in Chapter 12.
    Estuarine waters include bays
and tidal rivers that serve as nursery
areas for many commercial fish and
most shellfish populations, including
shrimp, oysters, crabs, and scallops.
Most of our Nation's fish and shell-
fish industry relies on productive
estuarine waters and their adjacent
wetlands to provide healthy habitat
for some stage of fish and shellfish
development. Recreational anglers
also enjoy harvesting fish that repro-
duce or feed in estuaries, such as
striped bass and flounder.

                                      the 34,388 square miles  of estuarine
                                      waters in the Nation (Figure 4-1).
                                      The States based 42% of their sur-
                                      vey on monitored data and evalu-

                                      (including best professional judg-
                                      ment by water quality managers).
                                      The States did not specify whether
                                      27% of the surveyed estuarine
                                      waters were  monitored or evalu-
                                      ated.
                                         The States constantly revise
                                      their survey methods in an effort to
                                      improve their accuracy and preci-
                                      sion. These changes limit the com-

                                      State survey methods undermine
                                      comparisons of estuarine informa-

                                      and toxic pollutants in fish tissues:
                                      The discrepancies in State monitor-
                                      ing and survey methods, rather than
actual differences in water quality,
often account for the wide range in
water quality ratings reported by
individual States.


General Water Quality

    EPA directs the States to rate
whether their water quality is good
enough to fully support a healthy
community of aquatic organisms
and human activities, such as swim-
ming, fishing, and drinking. The
States designate individual estuaries
for specific activities,  termed "indi-
vidual designated uses." EPA and
the States use the following termi-
nology to rate their water quality:

•  Good/Fully Supporting:  Good
water quality supports a diverse
community of fish, plants, and
aquatic insects, as well as the array
of human activities assigned to an
estuary by the State.

•  Good/Threatened:  Good water
quality currently supports aquatic
life and human activities on the
estuary, but changes in such things
as land use threaten water quality,
or data indicate a trend  of increas-
ing pollution  in the estuary.

•  Fair/Partially Supporting:  Fair
water quality supports aquatic cohi-
munities with fewer species of fish,
plants, and aquatic insects,  and/or
occasional pollution interferes with
human activities. For example, run-
off during severe thunderstorms
may temporarily elevate fecal  coli-
form bacteria densities and  indicate
that shellfish are not  safe to harvest
and eat immediately after summer
storms.

• Poor/Not Supporting:  Poor
water quality does not support a
healthy aquatic community and/or
prevents some human activities on
the estuary. For example, estuarine
waters may be devoid of fish for
more than a month each summer
because excessive nutrients from
runoff initiate algal blooms that
deplete oxygen concentrations.

• Poor/Not Attainable:  The State
has performed a use-attainability
analysis and demonstrated that use
support of one or more designated
beneficial  uses is not attainable due
to one of  six specific biological,
chemical,  physical, or economic/
social conditions (see Chapter 1 for
additional information).

    Most  States rate how well  an
estuary supports individual uses
(such as swimming and aquatic life
habitat) and then consolidate
individual use  ratings into an overall
water quality rating. An estuary
receives a poor overall rating if
water quality consistently fails to
support any one human activity or
a healthy aquatic community (see
Chapter 1 for a complete discussion
of use support).
    The States reported that 63% of
the surveyed estuarine waters have
good water quality that fully sup-
ports designated uses (Figure 4-2).
Of these waters, 6% are threatened
and might deteriorate if we fail to
manage potential sources of pollu-
tion.
    Some form of pollution or habi-
tat degradation impairs the
remaining 37% of the surveyed
estuarine waters. Twenty-seven
percent of the surveyed estuarine
waters have fair water quality that
partially supports designated uses.
Most of the time these waters pro-
vide adequate habitat for aquatic
organisms and support human
activities, but periodic pollution   •

    Individual use support informa-
tion provides additional detail about
water quality problems in our
Nation's surface waters. The States
are responsible for designating their
estuaries for State-specific uses, but
EPA requests that the States rate
how well their estuaries support five
standard uses so that EPA can
summarize the State data. The stan-
dard  uses are aquatic life support,
fish consumption,  shellfish  harvest-
ing, primary contact recreation
(such as swimming and diving), and
secondary contact recreation (such
as boating) (see Chapter 1  for a
description of each individual use).
Few States designate saline estuarine
waters for drinking water supply use
and agricultural  use because of high
treatment costs.
    Twenty-one States reported the
individual use support status of their
estuarine waters (see Appendix C,
Table C-3, for individual State infor-
mation). Most often, these States
examined aquatic  life conditions
and swimming use in their estuarine
waters (Figure 4-3). The States
reported that pollutants impact
aquatic life in 6,945 square miles  of
estuarine waters (30% of the
23,117 square miles surveyed for
aquatic life support) and violate
shellfish harvesting criteria in 3,302
square miles of estuarine waters
(26% of the 12,813 square miles
surveyed for shellfishing use sup-
port). Pollutants also violate swim-
ming  criteria in 3,263 square miles
of estuarine waters (15% of the
22,118 square miles surveyed for
swimming use support).

Water Quality
Problems Identified
in Estuaries

    Figures 4-4 and 4-5 identify the
pollutants and sources of pollutants
that impair (i.e., prevent from fully
supporting designated uses) the
most square miles of estuarine
waters, as reported by the States.
The two figures are based on the
same data (contained in Appendix
C, Tables C-4 and C-5), but each
figure provides a different perspec-
tive on the extent of impairment
attributed to individual pollutants
and sources. Figure 4-4 shows the
relative impact of the leading pollut-
ants and  sources in surveyed estua-
rine waters. Figure 4-5 presents the
relative impact of the leading pollut-
ants and  sources in estuaries with
identified problems (i.e., impaired
estuaries), a subset of surveyed
estuarine waters.
    The following sections describe
the leading pollutants and sources
of impairment identified in estuaries.
It is important to note that the
information about pollutants and
sources is incomplete because the
States cannot identify the pollutant
or source of pollutants impairing
every estuarine waterbody. In  some
cases, a State may recognize that
water quality does not fully support
a designated use, but the State may
not have adequate data to docu-
ment that a specific pollutant or
process is responsible for the impair-
ment. Sources are even more diffi-
cult to identify than pollutants and
processes.
Pollutants and  Processes
Impacting Estuaries

    Twenty-five States reported the
number of estuarine waters
impacted by individual pollutants
and processes, such as habitat
alterations (see Appendix C, Table
C-4, for individual State informa-
tion).  EPA ranks the pollutants and
processes by the geographic extent
of their impacts on aquatic life and
human activities (measured as es-
tuarine square miles impaired by
each pollutant or process) rather
than actual pollutant loads entering
estuaries. This approach targets the
pollutants and processes causing the
most harm to aquatic life and public
use of our waters, rather than the
most abundant pollutants in our
estuaries.
    Often, more than one pollutant
or process impacts a single estuarine
waterbody. In such cases, the States
and other jurisdictions count a
single square mile of estuary under
each pollutant or process category
that impacts the estuary. Therefore,
the percentages of estuarine waters
impaired by all the pollutant and
process categories do not add up to
100%.
    The States identified more
square miles of estuarine waters
polluted by nutrients and bacteria
than any other pollutant or process
(Figures 4-4 and 4-5). Fifteen States
reported that extra nutrients pollute
4,548 square miles of estuarine
waters (which equals 17%  of the
surveyed estuarine waters). As in
lakes,  extra inputs of nutrients from
human activities destabilize estua-
rine ecosystems. When temperature

URBAN  RUNOFF AND

the States, urban runoff and
storm sewers
   • affect 17% of all estuaries

     and
   • constitute 46% of all
     water quality problems

and light conditions are favorable,
excessive nutrients stimulate popula-
tion explosions of undesirable algae.
Decomposition of dead algae de-
pletes oxygen, which may trigger
fish kills and foul  odors. Explosive
growth of algae populations can
reduce light penetration and  inhibit
growth of beneficial aquatic plants.
Submerged aquatic plants provide
critical habitat for desirable shellfish,
such as scallops.
   Twenty-five States reported that
bacteria pollute 4,479 square miles
of estuarine waters (which equals
17% of the surveyed estuarine wa-
ters). Most States monitor harmless
bacteria, such as  Escherichia coli, that
inhabit the digestive tracts of hu-
mans and other warm-blooded
animals and populate sewage in
high densities. Bacteria provide
evidence that an estuary is contami-
nated with sewage that may con-
tain numerous viruses and bacteria
that cause illness in people. Most
States monitor the indicator bacteria
rather than run multiple tests to
detect the numerous harmful viruses
and bacteria  in sewage.
    Pathogenic viruses and bacteria
seldom  impact aquatic organisms
such as  fish and shellfish.  However,
shellfish can accumulate bacteria
and viruses from contaminated
water and cause'illness when
ingested. Therefore, the Food and
Drug Administration and the States
restrict the harvest and sale of shell-
fish grown in waters polluted with
indicator bacteria. Bacteria also
interfere with recreational activities
because some pathogens  can be
transmitted by contact with
            Figure 4-6

                Urban runoff and storm sewers are
                the leading source of impairment
                in estuarine waters
                                         Overloaded or improperly functioning
                                         sewage treatment plants may release
                                         waste that contains bacteria
           Failing septic systems
           may release bacteria
           Some bacteria, such as fecal colifonns, provide evidence that an estuary is contaminated with fecal material that
           may contain pathogenic bacteria and viruses harmful to people. Often, the pathogenic viruses and bacteria do not
           adversely impact aquatic life such as fish and shellfish. However, shellfish may accumulate bacteria and viruses
           that cause human diseases when ingested. Therefore, officials restrict shellfish harvesting in contaminated waters
           to protect public health. Bacteria also impair swiroming uses because some pathogenic bacteria and viruses can be
           transmitted by contact with contaminated water.

contaminated water or ingestion
during swimming (Figure 4-6).
    The States also report that oxy-
gen depletion from organic wastes
impacts 3,127 square miles (which
equals 12% of the surveyed
estuarine waters), habitat alterations
impact 1,564 square miles (which
equals 6% of the surveyed estuarine
waters), and oil and grease pollute
1,344 square miles (which equals
5% of the surveyed estuarine
waters). Dissolved oxygen depletion
is a widespread problem reported
by 21  States. In contrast, only one
State (Maryland)  reported extensive
impacts from habitat alterations,
and only one State (Louisiana)
reported extensive impacts from oil
and grease.
    Most States rate pollutants and
processes as major or moderate/
minor contributors to impairment.
A major pollutant or process is
solely responsible for an impact or
predominates  over other pollutants
and processes. A moderate/minor
pollutant or process  is one of mul-
tiple pollutants and processes that
degrade aquatic life  or interfere with
human use of estuarine waters.
    The States report that nutrients
have a major impact on more estua-
rine waters than any other pollutant
or process. The individual State
305(b) reports provide more
detailed information about the
severity of pollution  in specific
locations.
Sources of Pollutants
Impacting Estuaries

    Twenty-three States reported
sources of pollution related to
human activities that impact some
of their estuarine waters (see
Appendix C, Table C-5, for indi-  .
vidual  State information). These
States  reported that urban runoff
and storm sewers are the most
widespread source of pollution in
the Nation's surveyed estuarine
waters. Pollutants in urban  runoff
and storm sewer effluent degrade
aquatic life or interfere with public
use of 4,508  square miles of estua-
rine waters (which equals 17% of
the surveyed  estuarine waters)
(Figure 4-4).
    The States also reported that
municipal sewage treatment plants
pollute 3,827 square miles  of estua-
rine waters (14% of the surveyed
estuarine waters), agriculture pol-
lutes 3,321 square miles of estuarine
waters (12% of the surveyed estua-
rine waters),  and industrial dis-
charges pollute 2,609 square miles
(10%  of the  surveyed estuarine
waters). Urban sources contribute
more to the  degradation of estua-
rine waters than does agriculture
because  urban centers are  located
adjacent to most major estuaries.

 Ocean Shoreline

 Waters

    Thirteen of the 27 coastal States
 and Territories rated general water
 quality conditions in 5,208 miles of
 ocean shoreline. The surveyed
 waters represent 9% of the Nation's
 coastline (including Alaska's 36,000
 miles of coastline), or 23% of the
 22,421 miles of national coastline
 excluding Alaska (see Appendix C,
 Table C-6, for individual State infor-
 mation). Most of the surveyed
 waters (4,834 miles, or 93%) have
 good quality that supports a  healthy
 aquatic community and public
 activities (Figure 4-7). Of these
 waters, 225  miles (4% of the
 surveyed shoreline)  are threatened
 and may deteriorate in the future.
    Some form of pollution or habi-
tat degradation impairs the
 remaining 7% of the surveyed
shoreline (374 miles). Five percent

of the surveyed estuarine waters
have fair water quality that partially
supports designated uses. Most of
the time, these waters provide ad-
equate habitat for aquatic organisms
and support human activities, but
periodic pollution interferes with
these activities and/or stresses
aquatic life. Only 2% of the sur-
veyed shoreline suffers from poor
water quality that consistently
stresses aquatic life and/or prevents
people from using the shoreline for
activities such as swimming and
shellfishing.

Individual Use
Support
    EPA requests that the States rate
how well their ocean shoreline
waters support five standard uses so
that EPA can summarize the State
data. The standard uses consist of
aquatic life support, fish consump-
tion, shellfish harvesting, primary
contact  recreation (such as swim-
ming and diving), and secondary
contact  recreation (such as boating)
(see Chapter 1 for a description of
each individual use). Few States
designate saline ocean waters for
drinking water supply use and agri-
cultural  use because of high treat-
ment costs.
    The States provided limited
information on individual use
support in ocean shoreline waters
(Appendix C, Table C-7, contains
individual State information). Ten
States rated aquatic life support
and swimming use in their ocean
shoreline waters, but fewer States
rated their ocean waters for support
of shellfishing, fish consumption,
and secondary contact recreation.
General conclusions cannot be
drawn from information represent-
ing such a small fraction of the
Nation's ocean shoreline waters
(Figure 4-8).


Water Quality

Problems  Identified

in  Ocean Shoreline

Waters

     Only six of the 27 coastal States
identified pollutants and sources of
pollutants degrading ocean shore-
line waters (Appendix C, Tables C-8
and C-9, contain individual State
information). General conclusions
cannot be drawn from the
information supplied by these States
because these States border less
than 1 % of the shoreline along the
contiguous States. The six States
identified impacts in their ocean
shoreline waters from bacteria, met-
als, nutrients, turbidity, siltation, and
pesticides (Figures 4-9 and 4-10).
The six States reported that urban
runoff and storm sewers, industrial
discharges, land disposal of wastes,
septic systems, agriculture, unspec-
ified nonpoint  sources, and com-
bined sewer overflows (CSOs) pol-
lute their coastal shoreline waters
(Figures 4-9 and 4-10).

                                      EMAP  Estuaries Summary
                                         The Environmental Monitoring
                                      and Assessment Program (EMAP)
                                      has been developed jointly by EPA,
                                      the National Oceanic and Atmos-
                                      pheric Administration (NOAA), and
                                      the National Biological Survey (NBS)
                                      to  provide the public, scientists, and
                                      Congress with information to eval-
                                      uate the general health of the
                                      Nation's ecological resources. EMAP
                                      works with local, State, regional,
                                      and national resource managers to
                                      facilitate information transfer and to
                                      ensure that key questions are being
                                      addressed. Consequently, there is a
                                      growing interest in EMAP methods,
                                      indicators, data, and results among
                                      decision makers at all levels. The
                                      concepts used for specific  EMAP
                                      studies are being investigated at
                                      various  levels as a potential basis for
                                      monitoring and assessment guid-
                                      ance for States.
                                         EMAP conducts annual surveys
                                      to assess the presence of pollution
                                      and its effect on "ecological health"
                                      indicators such as aquatic plants,
                                      animals, and the habitats that sus-
                                      tain them. At present, the  program
                                      is developing the necessary tools to
                                      characterize the condition of the
                                      Nation's water resources with the
                                      goal of implementing long-term
                                      monitoring that will provide infor-
                                      mation on the overall health of the
                                     environment and the effectiveness
                                     of strategies implemented for pollu-
                                     tion prevention and control.  EMAP
                                     sampling was designed to yield
                                     statistically representative estimates
                                     of environmental condition.

                                                    currently being completed will help
                                                    to provide a framework for that
                                                    design. In addition, the current
                                                    studies can be used  to estimate the
                                                    regional health of estuarine waters

                                                    or support these plants and animals.
                                                    In addition, EMAP studies will evalu-
                                                    ate why certain areas are not able

                                                    organisms.
                                                       Between 1990 and 1993,

Results will include estimates of
the resources in these two provinces
as well as national estimates based
on this 55%.
Each summer since 1 990,
EMAP-E monitoring teams have
collected bottom sediments to
determine the number and types of
organisms present and to see if
these sediments contain harmful
pollutants. Fish have been collected,
identified, and examined for disease.
In addition, scientists have taken
water quality measurements includ-
ing dissolved oxygen, salinity, and
temperature.

In General . . .

The EMAP-Estuary study design
is based on a random site selection
process so that monitored sites, as a
whole, are statistically representative
of the Nation's estuarine waters.
Thus, information gained from the
EMAP study, which assessed roughly
55% of our estuaries, can be used
to estimate conditions of our estua-
rine resources on a national scale.
Based on the 1 990-1 993 pilot
projects, about 74% of the Nation's
estuaries are in good condition for
supporting a diversity of plants,
animals, and human uses. The
remaining 23% to 29% have poor
benthic (bottom-dwelling) and fish
community conditions and unac-
ceptable levels of pollution for
i I * 1
human uses such as commercial
shellfishing. Sediment contamina-
tion, affecting the diversity and
' ' r ' ;»'*•?
* ' •» '>•*'»






abundance of pollution-sensitive
benthic organisms, is a leading
cause of poor conditions in both the
Virginian and Louisianan Provinces.
Approximately 22% to 30% of
the Nation's estuarine waters are
categorized as degraded for some
human use including swimming,
boating, fishing, and walking along
the shore. The factors contributing
to this degradation are (1) water
clarity, which affects recreational
uses; (2) marine debris, which
affects aesthetics and wildlife health;
and (3) contaminants in the edible
portions of fish and shellfish.
In the Virginian Province,
marine debris is the most prevalent
source of human-use degradation;
water clarity and fish contamination
are local rather than regional issues.
In the Louisianan Province, marine
debris and water clarity are the
major contributors to human-use
t
degradation.
Overall, contaminant concentra-
tions in fish and shellfish are low,
with the exception of some heavy
metals. No fish or shellfish studied
contain PCB residues greater than
the health criteria set by the Food
and Drug Administration (FDA). The
overall incidence of fish contamina-
tion is low in both regions; how-
ever, elevated concentrations of
contaminants might be expected in
specific localities adjacent to con-
taminant sources. Periodic surveys
will allow scientists to track potential
changes in fish tissue residue levels

                                       Fish Diseases

                                          Between 1990 and 1993, over
                                       30,000 fish were examined for dis-
                                       ease. Only 154 (<0.6%) had exter-
                                       nal abnormalities. The EMAP-E data
                                       provide the first evidence that the
                                       frequency of pathologies in estua-
                                       rine fish is low. Bottom-dwelling fish
                                       (e.g., catfish) have the highest fre-
                                       quency of disease, 4 to 10 times
                                       more than other groups. The num-
                                       ber of fish with external pathologies
                                       increases in areas with multiple con-
                                       taminants in the sediments, regard-
                                       less of the area of the country. Data
                                       indicate that pathologies are local in
                                       nature and appear to be associated
                                       with increased contaminant
                                       loadings.

                                       and heavy metals) end up in fish
                                       and bottom sediments; however,
                                       these substances are not always
                                       present at levels that are toxic to
                                       marine life. EMAP-E took more than
                                       600 sediment samples during the
                                       pilot projects and examined them
                                      for 125 different contaminants. In
                                       general, the data show that about
                                       34% of the Virginian Province and
                                      6% of the Louisianan Province have
                                      a concentration of a contaminant
                                      above the ERM  criterion. The ERM
                                      criterion is the level of a contami-
                                      nant that will result in ecological
                                      effects approximately 50% of the
                                                    time (based on scientific literature
                                                    studies) and serves as a "red flag."
                                                    For example, if a contaminant is
                                                    found to be above the ERM crite-
                                                    rion, then marine organisms will  be
                                                    affected about half the time.
                                                       There are distinct differences in
                                                    the types of contaminants found in
                                                    the two provinces. The Virginian
                                                    Province is characterized by indus-
                                                    trial contaminants and some urban
                                                    pesticides; the Louisianan Province is
                                                    characterized by agricultural con-
                                                    taminants. The presence of toxic
                                                    sediments can have a direct effect
                                                    on aquatic life. Sediments are actu-
                                                    ally considered toxic when there is
                                                    greater than a 15% mortality rate in
                                                    organisms exposed to the sedi-
                                                    ments. Through  toxicity testing,
                                                    approximately 19% of the Virginian
                                                    Province sediments and 9% of the
                                                    Louisianan Province sediments have
                                                    been found to be toxic to estuarine
                                                    organisms.

                                                    Water Quality

                                                       Dissolved oxygen (DO) is a
                                                    fundamental requirement for all
                                                    marine life. A threshold concentra-
                                                    tion of 4 to 5 ppm (parts per mil-
                                                    lion) is defined by many States as a
                                                    water quality standard. A concentra-
                                                    tion of 2 ppm is  considered
                                                    extremely stressful to most organ-
                                                    isms.  DO levels have natural daily
                                                    and seasonal fluctuations and are
                                                    usually higher during daylight hours
                                                    due to photosynthesis, the produc-

                                                   waters and have  the greatest impact
                                                   on organisms that live in the sedi-

clams. Up to a quarter (9% to 25%)
of the bottom water area in the
Virginian Province has DO levels of
below 5 ppm, whereas 4% to 8%
has concentrations of less than 2
ppm. These depletions of oxygen
occur primarily in the Chesapeake
Bay. Less than 1 0% (2% to 8%) of
the Louisianan Province's bottom
waters have concentrations of less
than 2 ppm. However, of these,
about 50% are locations where
daytime concentrations exceed
5 ppm. Approximately 15% to 21%
of bottom waters in the Gulf of
Mexico have DO levels below
5 ppm.
Marine debris has multiple
negative effects, including entangle-
ment and/or ingestion by animals
and the economic cost of lost tour-
ism and beach cleanups. EMAP-E
estimates that 1 7% to 23% of the
Virginian Province and 1 2% to 22%
of the Louisianan Province have
marine debris either floating on the
water or lodged in the bottom sedi-
ments. This observed amount of
debris would correspond to 3.8
million acres out of more than 23.6
million total acres nationally. About
80% of the debris observed is cans,
glass, or paper; 1 5% appears to be
plastics.
Clear water, another factor
measured by EMAP-E, helps sustain
healthy and productive ecosystems
and is a trait that the public values.
Water clarity was defined as the
percentage of light reaching
1 meter depth. Less than 1 % of
the waters in the Virginian Province
have clarity of less than 1 0%
(primarily occurring in the upper
- • • . • ':.'-- :."';.
portions of large tidal rivers), and
15% to 19% have clarity of less
than 25%. In the Louisianan Prov-
ince, 20% of waters have less than
1 0% clarity, while about half of the
estuarine waters have clarity of less
than 25%. The vast majority of
waters with this low clarity are west
of the Mississippi Delta.
A Program in Transition
In 1 994, testing of ecological
indicators and sampling design
began in the Carolinian and Califor-
nian Provinces and was continued
for a final year in the Louisianan
Province. Also in 1 994, EMAP-E
began to expand its coverage to
include additional coastal ecosys-
tems, specifically coastal wetlands
and offshore waters. A study to
determine the best set of ecological
indicators for coastal wetlands was
completed, and monitoring pro-
grams were initiated for coastal
waters in the Southern California
Bight and the Gulf of Mexico
through cooperative efforts with the
State of California and NOAA.
The final year of province-wide
monitoring and assessment was
1 995 in the Carolinian Province
(second year) and the West Indian
Province (first year). For 1996, field
sampling is continuing in the mid-
Atlantic region (Delaware and
Chesapeake Bays and coastal areas),
and in regional EMAP programs
begun in 1 994. EMAP is continuing
research on biological indicators of
environmental condition and on the
statistical elements of a national
monitoring design.

                                     Background

                                        The National Oceanic and
                                     Atmospheric Administration (NOAA)
                                     created the National Status and
                                     Trends (NS&T) Program in 1984 to
                                     address national concerns over the
                                     quality of the coastal marine envi-
                                     ronment. One of its goals is to
                                     assess spatial distributions and
                                     temporal trends in chemical con- ,
                                     tamination. To meet that goal, the
                                     NS&T Mussel Watch Project was
                                     formed in 1986 to measure concen-
                                     trations of a broad suite of trace
                                     metals and organic chemicals in
                                     surface sediments and whole soft-
                                     parts of mussels and oysters
                                     collected from about 300 coastal
                                     and estuarine sites. The mussels and
                                     oysters are collected every year, and
                                     the resulting time series indicates
                                     trends in chemical concentrations.
                                     The most important result to date is
                                     that contamination  is decreasing for
                                     chemicals whose use has  been
                                     banned, such  as chlorinated hydro-
                                     carbons, or severely curtailed, such
                                     as cadmium. For other chemicals
                                     there is no evidence, on a national
                                     scale, for either an increasing or
                                     decreasing trend.

Temporal Trends
    A trend is a correlation between
concentration and time. There are
154 sites that have been sampled in
at least 6 years. The data for those
sites have been examined by a

    Given a 5% probability of
random data showing trends, there
could be 54 increases and 54
decreases that are not real trends.
Conceivably, none of the 41
increases are real. The important
point, however, is that decreases
greatly outnumber increases.

Wetlands
Introduction
    Wetlands are areas that are
inundated or saturated by surface or
ground water at a frequency and
duration sufficient to support (and
that under normal circumstances do
support) a prevalence of vegetation
typically adapted for life in saturated
soil conditions (Figure 5-1). Wet-
lands generally include swamps,
marshes, bogs, and similar areas.
This is the definition of wetlands as
it appears in the regulations jointly
issued by  the Army Corps of Engi-
neers (COE) and the U.S. EPA  (33
CFR Part 328.3(b), 40 CFR Part
232.2 (r), and 40 CFR Part
230.3(t)).
    A wide variety of wetlands exist
across the country as a result of
regional and local differences in
hydrology, vegetation, water chem-
istry, soils, topography, climate,
and other factors. Wetlands type
is determined primarily by local
 hydrology, the unique pattern of
water flow through an area. In
 general, there are two broad
 categories of wetlands:  coastal and
 inland wetlands.
     With  the exception of the Great
 Lakes coastal wetlands, coastal wet-
 lands are closely linked to estuaries,
 where sea water mixes with fresh
 water to form an environment of
 varying salinity and fluctuating
 water levels due to tidal action.
 Coastal marshes dominated by
 grasses, sedges, and rushes and
 halophytic (salt-loving) plants are
generally located along the Atlantic
and Gulf coasts due to the gradual
slope of the land. Mangrove
swamps, which are dominated by
halophytic shrubs and trees, are
common in Hawaii, Puerto Rico,
Louisiana, and southern  Florida.
    Inland wetlands are  most com-
mon on floodplains along rivers and
streams, in isolated depressions sur-
rounded by dry land, and along the
margins of lakes and ponds. Inland
wetlands include marshes and wet
meadows dominated by grasses,
sedges, rushes, and herbs; shrub
swamps; and wooded swamps
dominated by trees, such as

                                    wetlands provide many benefits,

 products for human use and oppor-
 tunities for recreation, education,
 and research.
    Wetlands are critical to the
 survival of a wide variety of animals
 and plants, including numerous rare
 and endangered species. Wetlands
 are also primary habitats for many
 species, such as the wood duck,
 muskrat, and swamp rose. For
 others, wetlands provide important
 seasonal habitats where food, water,
 and cover are plentiful.
    Wetlands are among the most
 productive natural  ecosystems in the
 world. They produce great volumes
 of food, such as leaves and stems,
 that breaks down in the water to
 form detritus (Figure 5-2). This
 enriched material is the principal
 food for many aquatic invertebrates,
 various shellfish, and forage fish that
 are food for larger  commercial and
 recreational fish species such as
 bluefish and striped bass.
    Wetlands help  maintain and
 improve water quality by intercept-
 ing surface water nunoff before it
 reaches open water, removing or
 retaining nutrients, processing
 chemical and organic wastes, and
 reducing sediment  loads to receiv-
 ing waters (Figure 5-3). As water
 moves through  a wetland, plants
 slow the water,  allowing sediment
 and pollutants to settle out. Plant
 roots trap sediment and are then
 able to metabolize  and detoxify
 pollutants and remove nutrients
 such as nitrogen and phosphorus.
    Wetlands function like natural
 basins, storing either floodwater that
 overflows riverbanks or surface '
water that collects in isolated
depressions. By doing so, wetlands
help protect adjacent and

downstream property from flood
damage. Trees and other wetlands
vegetation help slow the speed of
flood waters. This action, combined
with water storage, can lower flood
heights and reduce the water's ero-
sive potential (Figure 5-4). In agri-
cultural areas, wetlands can help
reduce the likelihood of flood dam-
age to crops. Wetlands within and
upstream of urban areas are espe-
cially valuable for flood protection,
since urban development increases
the rate and volume of surface
water runoff, thereby increasing the
risk of flood damage.
    Wetlands are often located
between rivers and high ground
(called uplands) and are therefore
  Figure 5-3
able to store flood waters and
reduce channel erosion. Wetlands
bind soil, dampen wave action, and
reduce current velocity through
friction. These properties are very
valuable for stabilizing shorelines
(Figure 5-5).
    Wetlands water storage capacity
also allows recharge of ground
water, which may be used as
sources of water for drinking or
agricultural  uses (Figure 5-6). El-
evated ground water tables and
water stored in wetlands are also
important for maintaining stream
base-flows. Water entering wetlands
during wet periods is released slowly
through ground water or as runoff,
moderating stream flow volumes

 necessary for the survival of fish,
 wildlife, and plants that rely on the
 stream (Figure 5-7).
     Wetlands produce a wealth of
 natural products, including fish and
 shellfish, timber, wildlife, and wild
 rice. Much of the Nation's fishing
 and shellfishing industry harvests
 wetlands-dependent species. A
 national survey conducted by the
 Fish and Wildlife Service in  1991
 illustrates the economic value of
 some of the wetlands-dependent
 products. Over 9 billion  pounds of
 fish and shellfish landed in the
 United  States in 1991 had a direct,
 dockside value of $3.3 billion. This
 served as the basis of a seafood
 processing and sales  industry that
 generated total expenditures of
 $26.8 billion. In addition, 35.6 mil-
 lion anglers spent $24 billion on
 freshwater and saltwater fishing. It is
 estimated that 71% of commercially
 valuable fish and shellfish depend
 directly or indirectly on coastal
 wetlands.

 Consequences
 of Wetlands  Loss
 and  Degradation

    The loss or degradation of wet-
 lands can lead to serious conse-
 quences, including increased flood-
 ing; species decline, deformity,  or
 extinction; and declines in water
 quality. The following discussion
 describes several examples of the
 consequences of wetlands loss and
 degradation.
    Floods continue to seriously
damage the property and liveli-
 hoods of thousands of Americans
despite expenditures of billions  of
local, State, and Federal dollars
 spent over the years to reduce
 flooding. Loss or degradation of
 wetlands intensifies flooding by
 eliminating the wetlands' capacity
 to absorb peak flows and gradually
 release flood waters.

 •  In Massachusetts, the U.S. Army
 Corps of Engineers estimated that
 over $17 million of annual flood
 damage would result from the
 destruction of 8,422 acres of wet-
 lands in  the Charles River Basin. For
 this reason, the COE decided to
 preserve wetlands rather than con-
 struct extensive flood control facili-
 ties along a stretch of the Charles
 River near Boston. Annual benefits
 of the preservation project average
 $2.1 million while annual costs
 average  $617,000.

 • The Minnesota  Department of
 Natural Resources  estimates that it
 costs the public $300 to replace the
 water storage capacity lost by
 development of 1  acre of wetlands
 that holds 12 inches of water. The
 cost of replacing 5,000 acres of
 wetlands would be $1.5 million,
 which exceeds the State's annual
 appropriation for flood control.

    Another consequence of wet-
 lands loss or degradation is decline,
 deformity from  toxic contamination,
 or extinction of wildlife and plant
 species. Forty-five percent of the
 threatened and  endangered species
 listed by  the U.S. Fish and Wildlife
 Service (FWS) rely directly or indi-
 rectly on wetlands for their survival.

•  The destruction  of wetlands
around Merritt Island and  St. John's
Island in  Florida has been identified
as a major contributor to the
extinction of the Dusky Seaside

Sparrow. The sparrow's habitat was
diked and flooded in an attempt to
control mosquitos, then drained and
burned to promote ranching. The
last Dusky Seaside Sparrow died in
captivity on June 16, 1987.

•  Over-logging of mature bottom-
land hardwood forests is believed to
have caused the extinction of the
Ivory Billed Woodpecker in the
United States. The clearing of bot-
tomland hardwood forests has  also
affected the  Louisiana  Black Bear, or
swamp  bear, by destroying  the
bear's habitat. With  its population
plummeting from the  thousands to
several hundred, the FWS recently
listed the Louisiana Black Bear as
"threatened" under the Endangered
Species Act.

•  Populations of Mallard Ducks and
Northern Pintail Ducks in North
America declined continually
between 1955 and the early 1990s.
In 1990, the number of Mallard
Ducks in the prairies of the  United
States declined 60% from the num-
ber counted in 1989 to the lowest
population figures on  record,
although recent data indicate that
waterfowl populations are rebound-
ing. The well-being  of waterfowl
populations is directly tied to the
status and abundance of wetlands.
As waterfowl populations are
squeezed into the remaining wet-
lands, confined conditions favor
outbreaks of avian cholera and other
contagious diseases in waterfowl.

     Wetlands loss and degradation
also reduce  water quality purification
functions performed by wetlands.
• The Congaree Bottomland Hard-
wood Swamp in South Carolina
provides valuable water quality
services, such as removing and sta-
bilizing sediment, nutrients, and
toxic contaminants. The total cost
of constructing, operating, and
maintaining a tertiary treatment
plant to perform the same functions
would  be $5 million.

•  Forested riparian wetlands play
an important role in reducing nutri-
ent loads entering  the Chesapeake
Bay. In one study,  a riparian forest
in a predominantly agricultural
watershed removed about 80% of
the phosphorus and 89% of the
nitrogen from the  runoff water
before it entered a tributary to the
Bay. Destruction of such areas
adversely affects the water quality of
the Bay by increasing  undesirable
weed growth and  algae blooms.

•  A study of two similar sites on
the Hackensack River in New Jersey
demonstrated the  increase in
erosion that results from the
destruction of marshlands. In the
study, marsh vegetation was cut at
one site and left undisturbed at the
other site. The  bank at the  cut site
eroded nearly 2 meters (more than
6 feet) in 1 year while the uncut site
exhibited negligible bank erosion.

    These examples illustrate the
integral role of wetlands in  our
ecosystems and how wetlands
destruction and degradation can
have expensive and permanent
consequences.  By  preserving
wetlands and their functions, wet-
lands will continue to provide many
benefits to people and the  environ-
ment

                                         It is estimated that over 200
                                      million acres of wetlands existed in
                                      the lower 48 States at the time of
                                      European settlement. Since then,
                                      extensive wetlands acreage has
                                      been lost, with many of the original
                                      wetlands drained and converted to
                                      farmland and urban development.

Twenty-tivo States have lost at least 50% of their original wetlands.
Seven of these 22 (California, Indiana, Illinois, Iowa, Missouri, Ken-
tucky, and Ohio) have lost more than 80% of their original wetlands.

Source:  Dahl, I.E., 1990, Wetlands Losses in the United States 1780's to 1980's,
       U.S. Department of the Interior, Fish and Wildlife Service.
 Today, less than half of our original
 wetlands remain. The losses amount
 to an area equal to the size of Cali-
 fornia (see Figure 5-8). According to
 the U.S. Fish and Wildlife Service's
 Wetlands Losses in the United States
 1780's to 1980's, the three States
 that have sustained the greatest
 percentage of wetlands loss are
 California (91%), Ohio (90%), and
 Iowa (89%).
    According to FWS status and
 trends reports, the average annual
 loss of wetlands has decreased over
 the past 40 years. The average
 annual loss from the mid-1950s to
 the mid-1970s was 458,000 acres,
 and from the mid-1970s to mid-
 1980s it was 290,000 acres. Agricul-
 ture was  responsible for 87% of the
 loss from the mid-1950s to the rnid-
 1970s and 54% of the loss from the
 mid-1970s to the mid-1980s.
    A more recent estimate of
 wetlands losses from the National
 Resources Inventory (NRI), con-
 ducted by the Natural Resources
 Conservation Service (NRCS), indi-
 cates that 792,000 acres of wet-
 lands were lost on non-Federal lands
 between  1982 and  1992 for a
yearly loss estimate of 70,000 to
 90,000 acres. This net loss is the
 result of gross losses of 1,561,300
acres of wetlands and gross gains; of
 768,700 acres of wetlands over the
 10-year period. The NRI estimates
are consistent with the trend of
declining wetlands losses reported
by FWS. Although losses  have
decreased, we still have to make
progress toward our interim goal of
no overall net loss of the Nation's
remaining wetlands and the long-
term goal of increasing the quantity
and quality of the Nation's wetlands
resource base.

    The decline in wetlands losses
are a result of the combined effect
of several trends: (1) the decline in
profitability in converting wetlands
for agricultural production;
(2) passage of Swampbuster in the
1985 and 1990 Farm Bills; (3) pres-
ence of the CWA Section 404 per-
mit programs as well as  develop-
ment of State management pro-
grams  (see Chapter 17); (4) greater
public  interest and support for wet-
lands protection; and (5) implemen-
tation of wetlands restoration  pro-
grams  at the Federal, State, and
local level.
    Nineteen States listed sources of
recent wetlands loss in their 1994
305(b) reports (Figure 5-9). Resi-
dential  development and urban
growth were cited as the leading
sources of current losses (see
Appendix D, Table D-1,  for indi-
vidual  State information). Other
losses were due to commercial de-
velopment; construction of roads,
highways, and bridges; agriculture;
and industrial  development.
    Several States and the District
of Columbia reported on efforts to
inventory wetlands. Some of the
programs are designed to augment
the FWS's National Wetlands  Inven-
tory (NWI), while others are
designed to produce independent
status  and trend information. Some
of the programs have already been
completed and others have been
authorized but not funded.

•  In 1994, the District  of Columbia
 adopted a new estimate of total
wetlands acreage generated by
 applying the Planogrid method to
 aerial  NWI maps. The finer detail
 and resolution of the new method-
 ology almost doubled previous esti-
 mates of wetlands acreage.
•  New Hampshire recently com-
pleted a wetlands mapping project
that translated LANDSAT digital
imagery into a geographic informa-
tion system (CIS) format. The
project included extensive field
verification. The CIS mapping sys-
tem revealed  many small wetlands
that were overlooked by previous
surveys. As a result, New Hamp-
shire's estimate of total wetlands
acreage climbed from 200,000 acres
to almost 400,000 acres.

•  In  1993, the North Carolina Divi-
sion of Environmental Management
(DEM) used hydric soils as a base-
line to inventory wetlands  in the
Coastal Plain, rather than NWI maps
used  in previous inventories. DEM
randomly selected 27 sample sites
of 9,900 acres each,  mapped pub-
lished soils data for each site, and
calculated the total area of hydric
soils in each site with a video soft-
ware  analysis package.

                                    Resources (DNR) is conducting a
                                    statewide inventory of wetlands as
                                    part of its Remote Sensing Program
                                    with cooperation from numerous
                                    agencies. The program utilizes digi-

                                        Wetlands monitoring  data are
                                    critical to the achievement of
                                    important national  goals,  such as no
                                    overall net loss of wetlands func-
                                    tions and values. With States and
                                    Tribes developing water quality
                                    standards for their wetlands, State
                                    and Tribal monitoring programs are
                                    critical for determining if wetlands
                                    are meeting their designated and
                                    existing  uses. Monitoring  data are
                                    also needed to prioritize wetlands
                                    for restoration and  protection and
                                    to define successful mitigation.
                                        Monitoring programs can pro-
                                    vide the data needed to identify

                                    monitoring programs are still in
                                    their infancy. Currently, no State is
                                    operating a statewide wetlands
                                    monitoring program.
                                       However, several States include
                                    a  few wetlands in their ambient
                                    monitoring programs, and a grow-
                                    ing number of States are imple-
 menting monitoring projects at
 selected reference wetlands that are
 relatively free from impacts. The
 States will use the data collected at
 these reference wetlands to define
 baseline conditions in healthy
 wetlands and standards to protect
 wetlands.

 • Every 3 years, Kansas collects
 water quality samples from seven
 wetlands (covering 25,069 acres)
 owned by the State or the Federal
 government. The State monitors
 one station per wetland for nutri-
 ents, minerals, heavy metals, clarity,
 suspended solids, pesticides, bacte-
 ria, algae, temperature, and
 dissolved oxygen.

 • Kentucky added several wetlands
 to its reference reach monitoring
 program to characterize chemical
 water quality, sediment quality, fish
 tissue concentrations of contami-
 nants, habitat conditions, and gen-
 eral  biotic conditions in each physi-
 ographic region of the State. The
 information will be used to develop
 designated uses and biological crite-
 ria for wetlands.

 • Minnesota initiated the Reference
 Wetlands Project to develop a basis
 for assessing the biological and
 chemical health of wetlands. The
 project is characterizing invertebrate
 communities, vegetation, amphib-
 ians, land cover, and water and
 sediment chemistry at 32 relatively
 undisturbed wetlands and three
 impacted wetlands. The  information
will provide the basis for determin-
 ing use support status and evaluat-
 ing wetlands health and  will help
the State determine if  restored
wetlands can achieve a condition
comparable to natural wetlands.

•  New Hampshire plans to monitor
a variety of parameters at five
wetlands throughout the State dur-
ing 1994-1995 to provide baseline

wetlands water quality standards.

Designated  Use
Support  in Wetlands

    The States,Tribes, and other
jurisdictions are making progress in
developing specific designated uses
and water quality standards for wet-
lands, but many States and Tribes
still lack specific water quality crite-
ria and monitoring programs for
wetlands. Without criteria and
monitoring data, most States and
Tribes cannot evaluate use support.
To date, only nine States and Tribes
reported the designated use support
status for some of their wetlands
(see Appendix D, Table D-1). Only
Kansas used quantitative data as a
basis for the use support decisions.

• California reported that 12% of
the 121,900 acres of surveyed wet-
lands fully supports aquatic life use
and 88% partially supports aquatic
life use due to metals, nutrients,
oxygen depletion, and salinity.
Sources impacting wetlands include
municipal wastewater treatment
plants, urban runoff and storm
sewers, and hydrologic and habitat
modifications.

•  The Coyote Valley Band of Pomo
 Indians in northern California classi-
fied all  1.6 acres of their wetlands as
 partially supporting uses for wildlife
 and use as a riparian buffer. The use
 support analysis was  based on
 reconnaissance surveys rather than
monitoring in the wetland. The
wetland is impaired by exotic spe-
cies, filling and  draining, and other
habitat alterations.

•  The Hoopa Valley Tribe in north-
ern California reported that all of its
3,200 acres of wetlands partially
support aquatic life use, religious
use, wildlife habitat use, and use as
a riparian buffer. Filling and drain-
ing, flow alterations, other habitat
alterations, and exotic species  impair
the wetlands. Agriculture, forestry,
construction, hydrologic modifica-
tions, and unknown sources have
degraded wetlands on the Hoopa
Valley Reservation.

• Iowa used best professional judg-
ment to determine the designated
use  support status of 83 publicly
owned wetlands covering 26,082
acres (about 69% of the State's
total wetlands). Iowa reported that
3% of the  surveyed wetlands  acre-
age fully supports aquatic life  use,
31 % fully supports aquatic life use
now but is threatened, 52% par-
tially supports aquatic life use, and
14% does  not  support aquatic life
use. Siltation, nutrients, habitat
alteration,  and  pesticides have sig-
nificant impacts on Iowa's wetlands.
The leading  sources of degradation
are  agricultural runoff and dewater-
ing activities.

•  Kansas used monitoring data to
determine use  support in nine pub-
licly owned wetlands (covering
25,069 acres) and qualitative  infor-
 mation to  assess one wetland (cov-
ering 70 acres). The State did not
survey the remaining 25 publicly
 owned wetlands covering 10,388
 acres. Kansas reported that 20% of

• Nevada surveyed use support in
36,169 acres (25%) of its 136,650
total acres of wetlands. Nevada
reported that 28%  of the surveyed
wetlands partially supports uses,
67% does not support uses, and
6% cannot attain designated uses.
The State reported that 100 acres
are impaired by ammonia, pH, and
organic enrichment and low dis-
solved oxygen concentrations.

• North Carolina used aerial photo-
graphs and soil information to rate
use support by current land use.
North Carolina rated wetlands on
hydric soils with natural tree cover
as fully supporting uses. Partially
supporting wetlands have modified
cover and hydrology but still retain
wetlands status and support most
uses. For example, pine plantations
still retain value for wildlife habitat,
flood control, ground water
recharge, nutrient removal, and
aquatic  habitat, although the modi-
fied wetlands support these uses less
effectively than undisturbed wet-
lands. Wetlands converted to agri-
culture or urban land use are classi-
fied as not supporting original wet-
lands uses.

    North Carolina used this meth-
odology to survey use support in
over 7 million acres of wetlands.
The State reported that 66% of the
surveyed wetlands fully supports
uses, 13% partially supports uses,
and 22% does not support uses.

•  Oklahoma assessed one wetland
covering 120 acres. The State classi-
fied all 120 acres of the wetland as
threatened.

    EPA cannot draw national con-
clusions about water quality condi-
tions in  all wetlands because the
States used different methodologies
to survey only 3% of the total
wetlands in the Nation.
    Summarizing State wetlands
data would also produce misleading
results because two States (North
Carolina and Louisiana) contain
91% of the surveyed wetlands acre-
age.
    More States and Tribes will
assess use support in wetlands as
they develop standards for wet-
lands. Many States are still in the
process of developing wetlands
water quality standards, which pro-
vide the baseline for determining
beneficial use support (see Chapter
13). Improved standards will also
provide a firmer foundation  for
assessing impairments  in wetlands
in those States already reporting use
support in wetlands.

    The States have even fewer data
to quantify the extent of pollutants
degrading wetlands and the sources
of these pollutants. Although most
States cannot quantify wetlands area
impacted by individual causes and
sources of degradation,  12 States
identified causes and 13 States iden-
tified sources known to  degrade
wetlands integrity to some extent
(Figures 5-10 and 5-11). These
States listed sediment as the most
widespread cause of degradation
impacting wetlands, followed by
flow alterations, habitat modifica-
tions, and draining. Agriculture
topped the list of sources degrading
wetlands, followed by urban runoff,
hydrologic modification, and natural
                                                                                  sources (see Appendix D, Tables D-3

    Currently, most States are not
equipped to report on the integrity
of their wetlands. Only nine States
and Tribes reported attainment of
designated uses for wetlands in
1994. National trends cannot be
drawn from this limited information.
This is expected to change, how-
ever, as States adopt wetlands water
quality standards and enhance their
existing monitoring programs to
more  accurately assess designated
use support in their wetlands.

Ground  Water Quality
    Ground water is a vital national
resource that is used for a myriad of
purposes. It is used for public and
domestic water supply systems, for
irrigation and  livestock watering,
and for industrial, commercial, min-
ing, and thermoelectric power pro-
duction purposes.  In many parts of
the Nation, ground water serves as
the only reliable source of drinking
and irrigation  water. Unfortunately,
this vital resource is vulnerable to
contamination, and ground water
contaminant problems are being
reported throughout the country. In
their 1994 305(b)  reports, States,
Tribes, and Territories  identified
contaminant sources and the associ-
ated contaminants that threaten the
integrity of their ground water
resources.  Controlling  these sources
of contamination and  preventing
further contamination of the
resource have become the focus
of numerous local, State, and Fed-
eral programs.
    This chapter contains informa-
tion provided  by 48 States, 2 Terri-
tories, and 5 Tribes in their 1994
305(b) reports. The 1994 305(b)
reports are based on guidelines,
developed by EPA, requesting that
each reporting agency characterize
the quality of  its ground water
resources.  Because few States and
Tribes possess the  capability to char-
acterize ground water quality using
ambient monitoring data, EPA asked
them to provide available informa-
tion on specific contaminant sources
and associated contaminants
degrading ground water quality.
And, for the first time, EPA asked
States and Tribes to provide infor-
mation on selected parameters that
will be used in the future to provide
an indication of spatial and tempo-
ral trends in ground water quality.
    This chapter presents an over-
view of ground water use in the
United States as well as a discussion
detailing State-identified sources of
contamination and contaminants
that are adversely impacting our
Nation's ground water quality. State
progress in the development of
ambient ground water monitoring
networks is highlighted.  The
progress made in developing
ground water indicators is also
described.

Ground Water  Use
in the  United States

    In 1990, ground water supplied
51 % of the Nation's population
with drinking water—the highest-
priority use of water. Overall,
ground water supplied approxi-
mately 20% (80.6 billion gallons per
day [bgd] out of  a total  408.4 bgd)
of all water uses in the United
States. These water uses include
public and domestic water supply,
irrigation,  livestock watering, min-
ing, and commercial, industrial, and
thermoelectric cooling applications.
Figure 6-1 illustrates the distribution
of ground water use among these
categories. As shown, irrigation

(63%) and public water supply
(19%) are the largest uses of
ground water withdrawals.
    One of the largest and most
important contributions of ground
water is not presented in Figure 6-1.
The volume of ground water that is
naturally discharged to streams and
other surface waterbodies, thereby
maintaining streamflow during per-
iods of low flow or drought condi-
tions, was previously unrecognized
and unquantified. This volume, 492
bgd, is measured using special
instruments or estimated using
stream gaging and hydraulic gradi-
ent data. The importance of ground
water flow into streams and other
surface waters cannot be underesti-
mated. Ground water can transport
contaminants to streams and affect
surface water quality and quantity,
which  may impact drinking water
supplies drawn from surface waters,
fish and wildlife habitats, swimming,
boating, fishing, and commercial
navigation. Modifications to the
quantity or quality of ground water
discharged into surface water eco-
systems can also have major eco-
nomic repercussions as a result of
adverse impacts on recreation, pub-
lic health, fisheries, tourism, and
general ecosystem integrity.
    The importance of ground
water to stream baseflow mainte-
nance  is illustrated in Figure 6-2,
which shows all of the major uses of
ground water in relation to stream
baseflow maintenance. Stream
baseflow maintenance accounts for
54% of ground water discharges.
The next highest use of ground
water is irrigation, which accounts
for 29% of national ground water
use.  Figure 6-3 shows that ground
water use for drinking water supply,
agricultural supply, industrial/

    commercial supply, and mining
and thermoelectric supplies varies in
different regions of the country. For
example, ground water is more
heavily used for drinking water and
industrial/commercial supplies in
eastern States and for drinking
water and agricultural supplies in
western States.
    Despite the variation in usage
across the Nation, ground water
used for drinking water supply is
one of the most critical uses. Data
reported by the U.S. Geological
Survey were used to estimate
ground water statistics related to
public water supply (PWS) and pri-
vate wells on a State-by-State basis.
Specifically, the data were used to
determine whether there was an
increase or a decrease in the volume
of ground water used for PWS from
1970  to 1990; the percent change
in volume during the same period;
the ratio of the change in ground
water use from 1980 to 1990 to the
change in surface water use during
the same period for PWS; the per-
cent of population dependent upon
ground water for drinking water the

                                        tion. To determine the susceptibility
                                        of aquifers to contamination from
                                        shallow (Class V) injection wells, EPA

                                           Ground water vulnerability is
                                        dependent  upon the geology of the
                                        physical system. However, popula-

                                        important as the greatest number of
                                        shallow injection wells occur in areas
                                        of high population density. Aquifer
                                        sensitivity is related to the potential
                                        for contamination to occur. Aquifers

    Although high-priority concerns
differ among States, the results of
the nationwide assessment show
that a significant part of the Nation
is highly susceptible to at least some
type of contamination. That such a
significant portion of the Nation's

to the need for contaminant
prevention.

                                   pollutant in the Bay, comes from
                                   ground water discharge. Agriculture
                                   is the primary source of these
                                   nitrates because farming is common
                                   in the huge watershed draining into
                                   the Bay. Along with  nitrates, pesti-
                                   cides also enter the Bay. Pesticides
                                   are used to control pests on land
                                   and may be destroying beneficial
                                   organisms in  ground water as well.
                                   Thus, the benefit that these organ-
                                   isms provide  in cleaning ground
                                   water before  it enters the Bay is lost.
                                   To further exacerbate the problem,
                                   the forests that surround the shore-
                                   line continue to be cleared as devel-
                                   opment spreads. Research shows
                                   that trees are effective in removing
                                   nitrates and other pollutants from
                                   ground water before it discharges to
                                   surface water, and thus another
                                   water cleaning mechanism is lost. In
                                   addition, the  development that
                                   removes the trees adds yet more
                                   pollutant load to the watershed.
                                   This general model, with minor
                                   variations, is common throughout
                                   the country.
                                       EPA recently published A Review

Discharge to Surface Water,* which
identified seven methods commonly
used to estimate the quantity of
ground water discharging to surface
water. Although these methods are
well established, published research
that describes loadings from ground
water for specific locations is not
abundant. Nevertheless, a review of
the scientific literature identified
more than 100 studies nationwide
in which contaminated ground
water was discharged  into and
contaminated surface water. For
example,

• In the Missouri Valley watershed,
ground water accounts for 84% to
95% of the nitrate loading to
surface water.

• On the St. John's River, Florida,
about 20% of chloride loading
comes from  ground water seeping
into canals that drain into the river.

• At the Mahantango Creek water-
shed in Pennsylvania, a link was
observed between the intensity of
corn production and concentrations
of atrazine in ground water. As corn
production and the use of atrazine
increased, higher concentrations of
atrazine were observed in  more
wells. Specifically, atrazine was

Florida, ground water discharge

and heavy metal concentrations
100 to 10,000 times above sea

•  In Cedar River, Iowa, the pesti-
cides atrazine and deethylatrazine
were found in the river and 75%
was contributed from ground water.

•  In the Indian River estuary in
Florida, dissolved reactive phosphate
was found and 99% came from
ground water discharge.
                 Microbial Paths of Contamination
      Various pathogenic microorganisms are also introduced into ground
  water and surface water as a result:of various,human activities; These;actiyi>-
  ties include malfunctioning septic systems, back-slphonage of water systems,
  and maintenance deficiencies. The most relevant diseases spread by these
  pathogens are those related to consumption of contaminated drinking
  water, including gastroenteritis, campylobacteriosis, and hepatitis A. The
  protozoan Cryptosporidium has recently been recognized as a significant
  human pathogen. Floods and other natural disasters can also cause patho-
  gens to enter ground water and surface water used for drinking water
  supplies.
      In the summer of 1994, State agencies in Illinois, Iowa, Kansas, Minne-
  sota, Missouri, Nebraska, North Dakota, South Dakota, and Wisconsin and
  the Centers for Disease Control and Prevention coordinated a survey of the
  contamination of well water. Samples were taken from 5,530 private wells
  evenly spaced across these States. Preliminary results of the survey indicated
  that coliform  bacteria were present in 41% of these wells. The presence of
  cpliform bacteria may indicate contamination by harmful bacteria and
  viruses. In the sampled  wells, Federal drinking water standards established
  for nitrates and atrazine in public water systems were exceeded in 14% and
  0.4% of these wells, respectively. The results are being analyzed for associa-
  tions  between well contamination and well construction practices and health
  effects.

Ground Water Quality
    Ground water moves slowly, on
the order of less than an inch to
tens of feet per day. Consequently,
contaminants introduced into the
subsurface  are less likely to be
diluted than those introduced into
more rapidly moving surface water.
The slow movement of ground
water often results in a delay in the
detection of ground water contami-
nation. In some cases, contaminants
introduced into the subsurface more
than 10  years ago are only now
being detected and affecting
ground water uses.
    While the larger ground water
resource is of good quality, localized
areas of  high demand and chemical
use can  be affected by contamina-
tion. This situation exists because
locations of more productive
ground water yields are often places
that allow  more infiltration and
recharge of aquifers, carrying con-
taminants  more easily to ground
water. This vast resource remains
exceedingly vulnerable to contami-
nation by toxic compounds, bacte-
ria, viruses, and inorganic contami-
nants. In one study of five midwes-
tern States, the  Ground Water
Protection Council* estimated that
between 15% and 48% of the land
area is underlain by highly vulner-
able aquifers.
     Contamination of ground water
typically occurs in localized areas.
These incidents are frequently seri-
ous and often pose threats to
human health or result in increased
costs to consumers. Many locations
within every State have shown
water quality degradation that
constrains the use of ground water
resources. As ground water quality
is degraded, Americans are becom-
ing increasingly aware that contami-
nated ground water is both difficult
and expensive to clean up.
    The following statistics help to
illustrate the prevalence of localized
ground water contamination
incidents:

•  More than 85% of abandoned
hazardous waste disposal sites
(Superfund sites) have some degree
of ground water contamination.
Most of these sites impact aquifers
that are currently used or could
potentially be used for drinking
water.

•  Of the contaminated aquifers at
Superfund sites, 62% discharge into
surface waters.  Of these aquifers,
38% are used to supply drinking
water. Nineteen percent of these
contaminated aquifers discharge to
sensitive ecological  environments.

•  At 49% of the Superfund sites
where cleanup costs are expected to
exceed $20 million, dealing with
large volumes of contaminated
ground water is a key factor
contributing to that cost.

•  Currently, 418 land disposal
facilities are subject to ground water
monitoring  requirements under the
Resource Conservation and Recovery
Act (RCRA). Of these, an estimated
37% are  undertaking measures to
clean up  existing ground water
contamination. The EPA estimates

 Do You Drink Ground Water?
   Ground water is water that is
   stored in the spaces between
 rocks underground. It is pumped
   to the surface for residential,
 commercial, and agricultural use.
 Over 80% of public water supply
 systems in this country depend at
 least partially on ground water for
- source water, 95% of the rural
- population use ground water  for

                                       • EPA estimates that 1.2 million
                                       federally regulated underground
                                       storage tanks (USTs) are buried at
                                       over 500,000 sites nationwide. An
                                       estimated 139,000 USTs have
                                       leaked and impacted ground water
                                       quality.

                                       • EPA estimates that the total num-
                                       ber of leaking USTs could reach
                                       400,000 in the next several years.

                                          The EPA requested that States
                                       provide information on the degra-
                                       dation of ground water resources
                                       used for public drinking water sup-
                                       ply. As a result, 21 States reported
                                       on the quality of ground water sup-
                                       plied  by a total of 20,294 public
                                       water systems that serve approxi-
                                       mately 52 million people. Among
                                       these States:

                                       • Nineteen reported incidents of
                                       public water systems that use
                                       ground  water exceeding the Maxi-
                                       mum Contaminant Level (MCL) for
                                       at least  one contaminant. These
                                       exceedances occurred in 3% of the
                                       ground-water-supplied public water
                                      systems and affected drinking  water
                                      quality for 1.4 million Americans.

                                      • Eleven reported incidents in
                                      which ground water supplied by
                                      public water systems exceeded the
                                      MCL for nitrate. Barium, arsenic,
                                      and fluoride were cited most
                                      frequently among the other 12
 inorganic contaminants reported to
 have exceeded MCLs.

 • Fifteen volatile organic com-
 pounds (VOCs) and eight pesticides
 were noted to have exceeded MCLs
 in ground-water-supplied public
 water systems. Among the most
 frequently cited of these com-
 pounds were trichloroethylene,
 tetrachloroethylene, and benzene.*
 Atrazine, alachlor, and lindane were
 the most frequently cited pesticides.

    Sixteen States also reported  on
 the occurrence of ground water
 contaminants  at levels that are
 approaching the MCL. The
 concentrations of these contami-
 nants in ground water do not yet
 present human health hazards.
 Nonetheless, they provide a clear
 indication that future uses of
 ground water may be impaired.  Of
 the 16 States reporting:

 •  Fourteen States detected nitrate
 at a  level between 50% and 100%
 of the MCL in ground water sup-
 plied by public water systems.
Among the 12 other inorganic con-
taminants reported to be approach-
 ing the MCL, the most frequently
cited were cadmium, nickel, sele-
nium, and thallium.

•  Fourteen VOCs and 13 pesticides
were reported at levels that
approached MCLs. The most
frequently cited of these com-
pounds were benzene, carbon
tetrachloride, and vinyl chloride."1"
Lindane, simazine, and aldicarb
were the most frequently cited
pesticides.
•Trichloroethylene is a carcinogen (i.e., cancer-causing substance) used in textiles, adhesives, and metal degreasers. Tetrachloroethylene is
 a carcinogen used in dry cleaning and other solvents. Benzene is a widely used carcinogenic component of gasoline, pesticides, paints, and
 plastics.
+ Carbon tetrachloride is a carcinogenic component of solvents and their degradation products. Vinyl chloride is a carcinogen that may leach
 from polyvinyl chloride pipe or be formed by the breakdown of other solvents.

Ground Water
Contaminant Sources

    Ground water quality may be
adversely impacted by a variety of
potential contaminant sources. EPA
presented a list of potential
contaminant sources in the 1994
305(b) guidelines and requested
each State to identify and rank the
specific sources that threaten their
ground water resources. Ranking
was based on the best professional
judgment of the State ground water
officials and took into account the
number of each  type of source in
the State, the location of the various
sources relative to ground water
used for drinking water purposes,
the size of the population at risk
from contaminated drinking water,
the risk posed to human health
and/or the environment from
releases, hydrogeologic sensitivity
(the ease with which contaminants
enter and travel  through soil and
reach aquifers), and the findings of
the State's ground water protection
strategy and/or  related studies.
    Figure 6-5 lists potential ground
water contaminant sources ranked
according to the number of States
that identified each source as a
 high, medium, low, or unspecified
 priority.  As shown, the greatest
 number of States reported that leak-
 ing underground storage tanks
 (USTs) are a  source of ground water
 contamination with 41 States rating
 USTs as a high-priority source of
 ground water contamination in their
 1994  305(b) reports. Montana  indi-
 cated that there have been 963
 confirmed releases from USTs and
 that half of these releases impacted
 ground  water resources. Leaking
USTs have also caused serious
ground water pollution problems in
Rhode Island with more than 511
leaking USTs identified in the State
since 1985. Many of these sites have
required active remediation of con-
taminated ground water. In several
cases, restoration of contaminated
ground water was deemed infea-
sible, and alternative measures had
to be taken to supply affected areas
with drinking water.
    The primary causes of leakage in
USTs are faulty installation and cor-
rosion of tanks and pipelines. It is
estimated that, on a national basis,
139,000 tanks have leaked and
impacted ground water quality, and
reports of leaking USTs continue to
increase. Rhode Island indicated that
new reports of leaking  UST sites
requiring investigation for potential
ground water contamination num-
bered 50 to 70 per year during
1992-1993. Montana indicates that
new reports of leaking  USTs come in
at a rate of 20 to 30 per month.
This rise in the number of reports of
leaking USTs most likely reflects
increased awareness, stricter require-
ments on site assessments upon
closure of tanks, and monetary aid
to assist responsible parties to clean
 up the contaminated sites. In addi-
tion, increased reporting of UST
 leaks may reflect an increase in leaks
 as older tanks corrode.
     In general, most USTs are found
 in the more heavily developed
 urban and suburban areas of a
 State. They are primarily used to
 hold petroleum products such as
 gasoline. Ninety-five percent of the
 USTs in Texas contain  petroleum
 products. Rhode Island reports that,
 of 255 active sites,  approximately
 75% involve motor fuels (gasoline

  106  Chapter Six Ground Water Quality
                                        and diesel fuel). The majority of
                                        these leaks at the active sites in
                                        Rhode Island occurred at gasoline
                                        service stations. North Carolina
                                        reported that leaking USTs
                                        accounted for 87% of the ground
                                        water contamination incidents
                                        occurring from October 1991
                                        through September 1993. Of these
                                        incidents, 86% were related to the
                                        release of gasoline. Maine reports
     that petroleum leakage has con-
     taminated over 200 private wells
     between 1990 and 1992.
        Septic tanks and shallow injec-
     tion wells were listed as the third
     and eleventh most common sources
     of ground water contamination,
     respectively. Shallow injection wells
     (classified as Class V wells in the
     Underground Injection Control
     Program) inject fluids into or above

underground sources of drinking
water. They include dry wells, septic
systems, geothermal reinjection
wells, industrial and utility disposal
wells, and aquifer recharge wells.
New jersey reports that in a four-
county study, including Passaic,
Somerset, Camden, and Ocean
Counties, subsurface discharges of
wastewater from industrial septic
systems, dry wells, and service
station drains are a major source of
drinking water contamination. One-
hundred and twenty-four private
wells and five municipal wells were
contaminated—half by subsurface
discharges.
    Contamination of drinking
water from  shallow injection wells
may take years to be detected in
nearby wells. A chemical company
in the Bethpage/Hicksville area of
New York disposed of industrial
wastewater containing a  carcino-
genic compound—vinyl chloride—
into sumps. Two million  gallons of
wastes were discharged each year
for 19 years. This led to extreme
contamination  of the Magothy aqui- •
fer. Fourteen wells, including five
municipal supply wells, were con-
taminated with industrial organic
wastes. An estimated 100,000
people were affected by the con-
taminated wells.
     One obstacle in remediating
ground water contaminated by
shallow injection wells is determin-
ing the responsible parties. Three
wells were closed in Burlington,
 Maine,  due to trichloroethylene
 (TCE) and tetrachloroethylene (PCE)
 contamination. The closure of the
wells affected 50% of the town's
 primary well field and  approximately
 20,000 people. Two nearby manu-
facturing plants are unconfirmed
but suspected sources of contamina-
tion. Both facilities have dry wells
and septic systems that contain TCE
and PCE. The town continues to
supply water to residents using a
wellfield that previously served as a
backup water supply.
    In severe cases, even when
responsible parties are required to
remediate the contaminated area,
costs  are high—often too high for
the responsible party or parties to
afford. From the 1950s through
1981, a thermostat manufacturer in
South Cairo, New York, poured
wastes containing TCE and PCE
sludges down drains connected to
an abandoned septic system. As a
result, high  levels of TCE and PCE
were  detected in five privately
owned wells in the vicinity. A 1983
Consent Order required the manu-
facturer to clean up the site, supply
bottled water, and install, monitor,
and maintain carbon filter systems
for the five affected homes.  In 1985,
the manufacturer filed for
bankruptcy, and  EPA has assumed
responsibility for  maintaining the
carbon filter systems and monitor-
ing. EPA has also installed two new
carbon filtration units and an air
stripping system  and drilled a new
well in an effort to provide clean
water. Future remedial action will
include the  provision  of an alternate
water supply through a pipeline at
estimated capital costs of
 $2,270,000 and  annual operation
and management costs of
 $100,000.
    A March 22, 1991, report
 prepared for EPA entitled  Drinking
 Water Contamination by Shallow
 Injection Wells estimated that shal-
 low injection wells contaminated
 the drinking water of approximately

                                     1.3 million people at a cost ranging
                                     from $30,000 to $3.8 million.

                                         EPA also requested that States
                                     identify and rank the contaminants
                                     impacting their ground water
                                     resources. This information was also
                                     based upon the best professional
                                     judgment of the State ground water
                                     experts. Factors that were consid-
                                     ered include the areal extent of
                                     contamination, the location of
  contamination relative to ground
  water supplies used for drinking
  water purposes, the size of the
  population at risk from drinking
  water threatened by the contami-
  nant, the risk posed to human
  health and/or the environment from
  this contaminant, hydrogeologic
  sensitivity, and findings of the
  State's ground water protection
  strategy or other reports.

generally associated with under-
ground and aboveground storage
tanks, and their frequent detection
in ground water is consistent with
the high  priority assigned by the
States to storage tanks as a
contaminant source.
    Petroleum is a complex mixture
of more than 200 different com-
pounds. Studies have found that
four compounds (benzene, toluene,
ethyl benzene, and xylenes) make
up  95% of the compounds
detected in ground water impacted
by  petroleum releases. It is generally
these compounds that are most
frequently detected in contaminated
ground water. Using this informa-
tion, Montana was able to relate
five incidents of benzene contami-
nation in public water supplies to
leaking USTs.
     Nitrate was the second most
common ground water contaminant
cited in State 305(b) reports.
Twenty-four States indicated that
nitrate was a major concern. Ten of
these States indicated that nitrate
was the prime contaminant of
concern. High concentrations of
nitrate in drinking water can cause
serious human health problems,
especially in babies. Exposure to
high concentrations of nitrate (>10
mg/L) in drinking water causes
methemoglobinemia, or blue baby
syndrome, an inability to fix oxygen
in the blood.
     Nitrate is soluble  in water, and,
as  a consequence, it is easily trans-
ported from the soil surface to
ground water. Nitrate is applied
extensively on agricultural fields,
residential lawns, and golf courses
to  promote crop and lawn growth.
Sources  of nitrate include fertilizer,
domestic wastewater and sludge,
and septic tanks. Natural
concentrations of nitrate in ground
water vary, but a concentration of
3 mg/L is often considered to be
typical outside of areas of naturally
high nitrate levels. Concentrations
measured above this level  are typi-
cally considered to be the  result of
human activity. Elevated concentra-
tions of nitrate in ground water are
frequently considered to be an
important indication of the
degradation of ground water
resources. The EPA drinking water
standard for nitrate is 10 mg/L.
    Following are highlights of
several State programs focusing on
nitrates.

Maine
    The Maine Soil and Water Con-
servation  Districts collected soil  from
the plow  layer of 249 corn fields as
part of a Manure Management
Project. Soil nitrate was found to be
twice the level  needed to  produce a
normal corn crop,  suggesting a
threat that the excess nitrate could
leach to ground water. In response,
the Maine Cooperative Extension
Service developed  guidelines for
manure utilization  that include
(1) the analysis of nitrate levels in
soils and  plants prior to fertilization,
and (2) fertilization according to
realistic crop uptake rates.

South Dakota
    The Oakwood Lakes-Poinsett
Rural Clean Water Program exam-
ined the impacts of agricultural
chemical  practices on  ground water
quality. A total of 114 monitoring
wells were installed at seven study
sites that represented both farmed

                                             Frequently Detected Pesticide
                                             Residues  in Ground Water
                   Ground water monitoring for
                agricultural chemicals during the
                past decade has shown that this
                vital resource is susceptible to con-
                tamination. The tabulated informa-
                tion on the following pages shows
                the results of recent monitoring for
                pesticides in the ground water of
                some States. These studies indicate
                that among the most frequently
                detected pesticides are those with
                active ingredients from the triazine
                (atrazine, cyanazine, simazine, and
                prometon) and amide (alachlor,
                metolachlor, and propachlor) herbi-
                cide families. While a number of
                pesticides have been detected in
                ground water, however,  very few
                are found at levels that exceed
                health-based standards for drinking
                water.
                   Atrazine is the common name
                of an herbicide that is frequently
                used to control weeds in corn,
                sorghum, and other agricultural
                crops. Atrazine has a high potential
                to be transported to ground water,
                and is the seventh  most frequently
                detected active ingredient tracked in
                the U.S. Environmental Protection
               Agency's  Pesticides in Ground Water
                Database.* Atrazine residues were
               found in 1,512 (5.6%) of the
               26,909 well samples that were
               collected for studies conducted
               across the United States from 1971
               to 1991. Only 172 'of the wells
 (0.6%) yielded samples in which
 atrazine levels exceeded the MCL.
    Alachlor is the common name
 of an herbicide that is commonly
 applied to weeds in corn, cotton,
 soybeans, and peanuts. Alachlor has
 a moderate potential to be trans-
 ported to ground water and is the
 ninth most frequently detected pes-
 ticide residue listed in the Pesticides
 in Ground Water Database. Of the
 26,856 wells tested for alachlor
 residues in the past two decades,
 543 (2%) contained detectable
 levels of this herbicide. Alachlor
 residues that exceeded the MCL for
 this compound were found in 101
 wells (0.4%).
    Simazine is the common name
 of an  herbicide used primarily to
 control weeds in corn, vineyards,
 citrus  orchards, and other agricul-
 tural crops. Simazine has a moder-
 ate potential to be transported to
 ground water. The Pesticides in
 Ground Water Database lists
 simazine as the tenth most fre-
 quently detected pesticide residual
found in ground water over the
 past two decades. Simazine residues
were found in 486 (2.2%) of the
22,374 well samples that were
reported from 1971 to 1991. Only
89 of the wells (0.4%) yielded
samples in which simazine levels
exceeded the MCL.

                                      A National  Look at  Nitrates*
                                           In addition to work being con-
                                       ducted by States, the U.S. Geologi-
                                       cal Survey evaluated nitrate concen-
                                       trations on a national basis. The U.S.
                                       Geological Survey conducted an
                                       analysis of approximately 12,000
                                       water samples collected from wells
                                       and springs in 18  of the 20 Study
                                       Units of the National Water Quality
                                       Assessment and five supplemental
                                       study areas.
                                           The analysis indicated that
                                       about 50% of the wells were
                                       characterized by elevated levels
                                       of nitrate (levels that exceeded
                                       3 mg/L, which is typically held  as
                                       the threshold indicating human
                                       impacts). Nitrate concentrations
                                       exceeded the EPA maximum con-
                                       taminant level (MCL) of 10 mg/L in
                                       approximately 21 % of the samples.
                                       Samples collected from agricultural
                                       areas had significantly higher nitrate
                                       concentrations than other land  use
                                       settings (for example, forest), with
                                       16% of the samples exceeding  the
                                       MCL. The nitrate concentrations
                                       were generally highest in the North-
                                       eastern, Northern Plains, and Pacific
                                       States. This reflects the fact that
                                       much of the agricultural land in
                                       these regions of the country is
                                       underlain by permeable, more well-
                                       drained materials, such as unconsoli-
                                       dated sand and gravel, or fractured
                                                     carbonate bedrock. It was shown
                                                     that nitrate concentrations were
                                                     highest in areas of sandy soil.
                                                         The analysis indicated that
                                                     nitrate concentrations exceeding the
                                                     MCL were most frequently detected
                                                     in irrigation and stock wells (16%)
                                                     as opposed to private wells (9%)
                                                     and public water supply wells (1 %).
                                                     However, EPA still urges well owners
                                                     who know or suspect that their
                                                     wells are affected  by nitrates to have

                                                     wells, EPA recommends an
                                                     approach that focuses on pollution

                 Occurrence of Nitrate Concentrations Associated
                     with Hydrogeologic and  Land Use Factors
Forest land had significantly
lower concentrations of nitrate
in ground water than other
land use settings.
22% of wells in agricultural areas
exceeded the MCL for nitrate.

9% of private wells and 1 % of
public supply wells exceeded the
MCL for nitrate.

16% of irrigation and stock wells
exceeded the MCL for nitrate.
Median nitrate concentrations
were highest in areas with
sandy soils.
Concentrations were greatest in
unconsolidated sand and gravel
and in fractured carbonate
bedrock aquifers.

  At shallow depths, nitrate
  concentrations were higher in
  well-drained areas where the
  water table was >5 feet deep.

                                     nitrate concentrations were found in
                                     the top 20 feet of the aquifer, and
                                     nitrate concentrations were signifi-
                                     cantly higher at the farmed sites.

                                     water unfit for consumption. In
                                     addition, high nitrate levels occur in
                                     Marana, St. David, Quartzsite,  Bull-

                                     Protection Division (EPD) sampled
                                     over 5,000 shallow domestic drink-
                                     ing water wells for nitrate/nitrite.
                                     Results indicate that only 1 % of the
                                     5,000 wells is characterized by
                                     nitrate  concentrations that exceed
                                     the MCL of 10 mg/L for nitrate in
                                     drinking water. Water from 97% of
the wells is characterized by nitrate
concentrations of less than 5 rng/L.
Although it does not appear that
nitrate is a widespread problem in
Georgia, the EPD observed a very
slight increase in average nitrate
concentrations in the  recharge areas
of some Coastal Plain aquifers.
These increases may indicate a
future increase in nitrate in the
down-dip confined  portions  of the
aquifers. EPD will continue to moni-
tor changes in the aquifers.

Iowa

    Agriculture, Iowa's largest indus-
try, is currently the  primary source
of ground water contamination in
the State. One of the  most signifi-
cant impacts  is related to the appli-
cation of commercial fertilizers. An
estimated 30% to 50% of the nitro-
gen applied as fertilizer to Iowa
farm acres is volatilized and lost to
the atmosphere or is lost through
infiltration through the soil. Cur-
rently, approximately  18% of the
State's rural population is served by
water with nitrate concentrations in
excess of the MCL (10 mg/L as
nitrogen). However, only 10 out of
1,130 ground-water-based commu-
nity public water supplies (PWSs)
have levels of nitrate exceeding the
MCL. High  levels of nitrate affect a
relatively low percentage of the
population of lowans served  (0.3%).

Ground Water
Monitoring

    Section 106(e) of  the Clean
Water Act requests that each State
monitor the quality  of its ground
water resources and report the
status to Congress biennially. The
most comprehensive approach to

determining overall ground water
quality is to use an ambient ground
water monitoring network. How-
ever, the expense associated with
installation and maintenance of such
a network is often high and,
depending upon State priorities, it
may be prohibitive. Despite this,
many States are taking the initiative
to develop programs designed to
evaluate the quality and vulnerabil-
ity of their ground water resources,
to identify potential threats to
ground water quality, and to
determine ways to  protect their
ground water resources from degra-
dation. Thirty-three States indicated
that they have implemented state-
wide ground water monitoring  pro-
grams that focus on one or more
contaminants. This is an increase of
four States from what was reported
in 1992. Additionally, six States
indicated that they are in the pro-
cess of developing similar programs.
Following is a brief description of
several State monitoring programs.


Pennsylvania - Fixed
Station and Ambient
Monitoring Programs

    To improve the effectiveness of
its ground water resource protection
efforts, the Pennsylvania Bureau of
Water Quality Management devel-
oped two ground water quality
monitoring programs—the Fixed
Station  Monitoring Network and the
Ambient Ground Water Quality
Survey Programs. These joint pro-
grams enable Pennsylvania to
(1) detect emerging ground water
problems, (2) evaluate the impacts
of unmonitored sources of pollution,
and (3) assess the overall
effectiveness of their regulatory
program.
    Pennsylvania's Fixed Station
Monitoring Program was developed
following division of the State
into 478 ground water basins
(Figure 6-7). These basins were then
prioritized based on ground water
use, land use (potential unmoni-
tored sources of pollution), and
environmental sensitivity. The 50
highest ranking  basins were selected
for inclusion in the Fixed Station
Monitoring Network Program.
    To date, 537 ground water
monitoring stations have been
established in 20 basins covering
2,318 square miles. The average
ground water basin  is 125 square
miles in size and includes 25 moni-
toring locations, which are selected
to represent the ambient ground
water quality of a 4-square-mile
area. Each ground water sample is
analyzed for 27  parameters.

                                    initiated in 1988 to obtain ground
                                    water quality data in those basins
                                    not covered by the Fixed Station
                                    Program. Because these basins are
                                    considered to be  less vulnerable,
                                    ground water samples are sched-
                                    uled to be collected only two times.

work designed to (1) establish the
baseline water quality of the major
aquifer systems in the State,
(2) detect and predict changes in
ground water quality resulting from
the effects of various land use activi-
ties and potential sources of con-
tamination, and (3) disseminate to
local governments and the  public
water quality data generated by the
network. The  Florida Network has
three components: the Background
Network, the  Private Well Survey,
and the Very Intense Study Area
Network.
    The Background Network was
designed to help define background
water quality using  a statewide grid
of wells that collectively tap all
major aquifers, including the
surficial, intermediate, Floridan, and
Claiborne aquifers (Figure 6-8).
One-third of the wells are sampled
annually with  a complete rotation of
wells every 3 years.  Approved data
are available to the  public on the
Florida Ground Water Quality Moni-
toring Network Electronic Bulletin
Board and in three State publica-
tions.
    The Private Well Survey provides
an evaluation  of water quality in
private drinking water wells serving
families in 67  Florida counties;. The
survey calls for 50 private water
wells to be sampled in each indi-
vidual county. To date, sampling in
23 counties has been completed.
    Twenty-three areas believed to
be highly susceptible to ground
water contamination based  on
predominant land use and
hydrogeology are being studied as
part of the Very Intense Study Area
Network. A total of 461  wells make
up this network, which is designed
to monitor the effects of multiple

quality within a segment of an aqui-
fer. The land uses represented are
urban, suburban, industrial, agricul-
tural, and  mixed. Cumulative moni-
toring data will be compared to
similar parameters in the Back-
ground Network representing the
same aquifer segment to determine
the effects of land use and site
hydrogeology upon ground water
quality.

Kansas - Assessing
Temporal and Spatial
Trends

    Kansas established a Ground
Water Quality Monitoring Network
in 1976 to procure long-term, state-
wide ground water quality data for
use in the identification  of temporal
and spatial trends related to
(1) alterations in land use,
(2) application of land treatment
methods and other nonpoint source
best management practices, (3)
changes in ground water availability
or withdrawal rates, and (4) varia-
tions in climatological conditions
within the State. In addition, the
network is intended to assist in the
identification of ground water
contamination problems.
    The network currently consists
of 242 wells (Figure 6-9), including
public water supply wells (71%),
irrigation wells (14%), private
domestic wells (10%), multiple use
wells (3%), livestock watering wells
(1 %), and industrial supply wells
(1%). During the period 1990-
1993, 599 samples were analyzed
for common inorganic chemicals
and heavy metals; 285 samples
were analyzed for pesticides; 110
samples were analyzed for volatile
organic chemicals; and  105  samples
were analyzed for radionuclides. In
evaluating the data, 103 instances
were found in which the chemical
quality of the raw ground water
samples exceeded State drinking
water standards. Of these, 71 were
related to the presence of nitrate.


Wisconsin  - Pesticide
Monitoring  Program

    Wisconsin developed a pesticide
monitoring program in response to
the detection of aldicarb in 1980 in
ground water near Stevens Point.
Initially the monitoring program
focused on aldicarb; however, it was
expanded in 1983 to include addi-
tional pesticides (e.g., atrazine), and
several studies were initiated to
determine the potential impact of
pesticide use on ground water
quality. Following are the results of
four studies:

                                     detected at 25 of the 35 study sites
                                     and alachlor was detected at 7 of
                                     the 23 study sites.

 pesticides were detected in 57 of
 the 69 resampled wells and 63 of
 the other 212 wells.

 • To better understand pesticides
 and nitrates in ground water, the
 Wisconsin Department of Agricul-
 ture, Trade, and Consumer
 Protection sampled nearly 2,200
 rural wells for atrazine and triazine
 herbicides. Sixteen percent, or 351
 of 2,187 wells, contained detectable
 concentrations of triazine-class
 compounds.

    In response to concerns about
 pesticides in ground water, Wiscon-
 sin adopted an administrative rule
 to regulate atrazine use starting with
 the 1991 growing season. This rule
 has been revised in each subsequent
 year to account for additional
 atrazine data. Application rates are
 limited statewide based on  soil
 texture and former use. The use of
 atrazine is prohibited in certain
 areas of the State. Throughout the
 rest of the State, a rate of applica-
 tion is required that is more strin-
 gent than Federal recommended
 limits.

 Arkansas  - Ambient
 Ground Water
 Monitoring

    The Arkansas Department of
 Pollution Control and Ecology has
 established an ambient monitoring
 program at various locations state-
wide that enables the State to
gather background ground water
quality data from various aquifers in
the State. Arkansas monitors water
quality in 100 wells and 10  springs
once every 3 years. The wells and
springs are monitored for specific
constituents likely to be found in

the respective areas. Monitoring
wells located at industrial or landfill
sites regulated by the Resource Con-
servation and Recovery Act (RCRA)
or the Comprehensive Environmen-
tal Response, Compensation, and
Liability Act (CERCLA) are monitored
at least annually, but only for indica-
tor parameters required by the
regulations.


Ohio - Tracking Ground
Water Quality Using CIS

    The Ohio Environmental Protec-
tion Agency Division of Drinking
and Ground Waters is responsible
for characterizing Ohio's ground
water quality. The Division has col-
lected an extensive amount of
ground water quality data through
three monitoring programs:  the
Ambient Network, the  Pollution
Source Network, and the Nonpoint
Source Network. The Ambient
Network currently includes approxi-
mately 200 well stations at nearly
150 sites. Of the total sites, roughly
110 (70%)  are public water systems
and roughly 40 (30%)  are indus-
trial/commercial water suppliers.
Raw water samples are collected
semiannually and are analyzed for a
series of inorganic constituents.
Organic constituents are analyzed at
least annually.
    Until recently, the ambient
ground water data were kept solely
in hard-copy files. However, during
the past 2 years, the data were
entered  into a comprehensive data-
base system, and locationa'l informa-
tion pertaining to each well station
was entered into a CIS. In using the
CIS program, the Ohio EPA has
gained the  ability to provide both
graphical and numerical summaries
of their monitoring data. Several
preliminary plots are presented in
Figures 6-10 and 6-11.

Indicators of Ground
Water Quality

    Developing the ability to char-
acterize trends in ground water
quality over space and time was
one of the key recommendations of
EPA's 1986 Ground-Water Strategy.

Ground Water Quality Indicators
EPA's 1 986 Ground-Water Strat-
egy recommended that States
develop the ability to characterize
trends in ground water quality over
time. To support this goal, EPA's
Ground Water Protection Division
has been involved in the Intergov-
ernmental Task Force for Monitoring
Water Quality (ITFM), which has
developed a set of environmental
indicators that EPA and the States
may use to target monitoring efforts
and set priorities in ground water
protection activities.
Selection of ground water indi-
cators by the ITFM was based on
their relevance to important water
quality issues, such as human health
protection, monitoring objectives,
and the existence of appropriate
analytical methodologies. The fol-
lowing criteria were considered in
the selection of indicator parameters
for ground water monitoring:

• Is the indicator parameter poten-
tially toxic to human health and the
environment, livestock, and/or
beneficial plants?

• Does the presence of the
parameter (e.g., hardness, iron,
taste, odor, color) impair the suit-
ability of the water for general use?

• Is the parameter of concern in
surface water and is it easily
transported from ground water to
surface water?

1 , • ': ': ••;
m Is the parameter an important
"support variable" for interpreting
the results of physical and chemical
measurements (e.g., temperature,
specific conductance, major ion
balance, depth to the water table)?

• Is analysis of the parameter
affordable using well-established
analytical methods at appropriate
minimum detection and reporting
levels necessary to achieve the
objectives of the study?

Due to regional differences in
the relative importance of water
quality issues and the potential for
significant differences in the objec-
tives of monitoring programs,, no
one set of indicators is suitable or
appropriate for all monitoring pro-
grams. However, the following table
provides examples of ground water
monitoring parameters that could
be considered for monitoring in
areas of differing land use and con-
taminant sources. The table focuses
on classes of contaminants, includ-
ing volatile organic compounds
(VOCs), semivolatile organic com-
pounds (SVOCs), petroleum hydro-
carbon compounds, pesticides, and
pathogens. The table does not
include physical indicators such as
color, odor, pH, specific conduc-
tance, temperature, or total
dissolved solids because these six
indicator compounds are suggested
for each of the categories in the
table.

                                     characterizing ground water quality
                                     does not exist for purposes of this
                                     report. To amend this problem, the
                                     Office of Ground Water and Drink-
                                     ing Water developed a set of indica-
                                     tors to track progress and set priori-
                                     ties in ground water protection
                                     efforts. The initial (1992) set of
                                     ground water indicators included

                                     • MCL violations in public drinking
                                     water systems supplied by ground
                                     water, and the population at risk
                                     from these violations

                                     •  Extent of ground water contami-
                                     nation resulting from hazardous

                                     risk from exposure to this contami-
                                     nation

                                     •  Detections and levels of VOCs  in
                                     ground water

                                     •  Detections and levels of nitrates
                                     in ground water

                                     •  Extent of leachable agricultural
                                     pesticide use.

                                         In its guidelines for preparation
                                     of the 1992 State 305(b) reports,
                                     EPA encouraged States to use one
                                     or  more of the above indicators to
                                     characterize ground water quality.
                                     As  development of ground water
                                     indicators progressed, more explicit
                                     guidance was provided to the States
                                     for preparation of their 1994 State
                                     305(b) reports.
                                         The 1994 guidelines focused on
                                     four indicators specifically selected
                                     to provide a relative indication of
                                     the condition of ground water
                                     resources. The selected indicators
                                     were based on existing data and/or
                                     data that could readily be collected
 by the States over time. Where data
 were available, the States were
 encouraged to report the following:

 • Number of MCL exceedances for
 ground-water-based or partially
 ground-water-supplied community
 water systems

 • Number of ground-water-based
 or partially ground-water-supplied
 community water systems with
 reported MCL exceedances

 • Number of ground-water-based
 or partially ground-water-supplied
 community water systems with
 detections between 50% and 100%
 of the MCLs

 • Number of ground-water-based
 or partially ground-water-supplied
 community water systems that have
 local Wellhead Protection Programs
 in place.

    Although this was the first time
 EPA had requested information
 specific  to ground-water-based or
 partially ground-water-supplied
 public water systems, 21 States
 were able to provide quantitative
 data characterizing at least one of
 the above indicator parameters.
 States most frequently reported the
 total number of samples analyzed
for metals, VOCs, pesticides, and
 nitrates, along with the number of
 exceedances in each category.
    The above set of indicator
 parameters is being refined so that,
over time, it can be used to detect
and predict changes in ground
water quality resulting from human
effects and to assess the overall
effectiveness of State ground water
monitoring programs.

Ground Water: What
We Still Need to
Know

    We are continuing to learn a
great deal about the nature and
quality of our Nation's ground
water.  Still, there is much we do
not yet know about how to most
effectively protect and preserve this
vast and  often vulnerable resource.
    While the importance of ground
water as  a source of water in private
wells is recognized, the quality of
the water drawn from those wells is
largely unknown. There are indica-
tions that private wells are vulner-
able to contamination from micro-
organisms, nitrates, and  pesticides.
The occurrence of viruses in ground
water and their impacts  on private
drinking  water wells are  poorly
understood. Furthermore, the risks
associated with redirecting surface
water runoff into surface
impoundments and infiltration
ponds are frequently  overlooked.
    Whereas ground  water protec-
tion measures are accepted as a
"good idea," the performance of
these measures in improving the
quality of vulnerable ground water
has not been tested. What are the
differential impacts of nonpoint
source best management practices
on ground water and surface water?
How effective are wellhead protec-
tion approaches in areas with frac-
tured bedrock, sinkholes, or areas
near surface water features?  What
are the indicators that should be
used to track ground water quality
and assess change over time?
   We are only beginning to
understand the capacity of the land
to assimilate contaminants without
adversely affecting the use of the
ground water.  Scientists have only
begun to explore the effectiveness
of natural ecosystems in processing
and degrading contaminants. Many
people are able to drink untreated
ground water because natural pro-
cesses improve water quality. Natu-
ral ground water systems  may
remove contaminants that conven-
tional treatment does not address,
such as pesticides, heavy metals,
and a variety of toxic chemicals
present at low concentrations.
Ground water organisms are
continually found and identified, yet
their function in contaminant degra-
dation and their impacts on ground
water quality are only beginning to
be understood. The interactions
between ground water and surface
water are known to be  significant at
the local level, but we do not often
recognize the larger-scale implica-
tions on the quality of both
resources.
    Our continued quest for high
quality and representative informa-
tion about the status of our ground
water resources will help to answer
these questions. Through a greater
understanding of how human activi-
ties have influenced the quality of
our waters, we can better ensure
the long-term availability of high-
quality water for future generations.

Public  Health  and
Aquatic  Life  Concerns
    Water pollution threatens public
health by contaminating seafood,
drinking water supplies, and recre-
ational waters with toxic substances
as well as pathogenic viruses and
bacteria, which cause disease.
Aquatic organisms tolerate most
bacteria  and viruses pathogenic to
humans, but many aquatic organ-
isms are more sensitive to toxic
substances than humans are.
Aquatic organisms also suffer if
chemical and physical  conditions
exceed an acceptable range. Impor-
tant chemical and physical condi-
tions include acidity (pH), dissolved
oxygen concentration, and
temperature.


Public  Health

Concerns


Toxic Pollutants

    Health officials link waterborne
toxic pollutants, such as mercury,
PCBs, and some pesticides with
human birth defects, cancer,
neurological disorders, and kidney
ailments. Once discharged to sur-
face waters, these toxicants persist
in the sediments and contaminate
the food chain and the overlying
water. Waterborne toxicants can
enter human systems via ingestion
of contaminated fish, shellfish,  or
drinking  water supplies. Swimmers
may also swallow toxic substances
or absorb toxic pollutants through
skin exposure in contaminated rec-
reational waters. Fish and shellfish
contamination usually poses a
greater human  health risk than does
contaminated drinking water or
recreational waters because fish and
shellfish concentrate many toxic
substances in their tissues (see
sidebar, page 128). As a result, the
concentration of toxicants within
fish and shellfish tissues may be
from ten to one million times the
concentration of toxicants in the
surrounding waters.

Fish Consumption
Advisories

    States issue fish consumption
advisories to protect the public from
ingesting harmful quantities of toxic
pollutants in contaminated fish and
shellfish. In general, advisories rec-
ommend that the public limit the
quantity and frequency of consump-
tion of fish caught in specific water-
bodies. The States tailor individual
advisories to minimize health  risks
based on contaminant data col-
lected in their fish tissue sampling
programs. Advisories may com-
pletely ban fish  consumption  in
severely polluted waters or limit fish
consumption to several meals per
month or year in cases of less severe
contamination. Advisories may tar-
get a subpopulation at risk (such  as

 Bioaccumulation  of Pollutants In  the Food Chain

    Certain organic pollutants (such as PCBs and DDT) have two prop-
erties that lead to high bioaccumulation rates. These pollutants are
hydrophobic (i.e., do not have an affinity to water) and thus attach to
the surface of particulates such as clay particles and small aquatic plants
called phytoplankton. These organic pollutants are also lipophilic (i.e.,
have an affinity to lipids or fatty tissues) and readily dissolve in fatty
tissues of plants and animals. As a result, these pollutants biologically
accumulate (bioaccumulate) in phytoplankton at concentrations that
greatly exceed the pollutant concentrations in surrounding waters,
which may be so low that they cannot be measured even by very
sensitive methods.
    Small fish and zooplankton (microscopic grazers) consume vast quanti-
ties of phytoplankton. In doing so, any toxic chemicals accumulated by the
phytoplankton are further concentrated in the fish, especially in their fatty
tissues. These concentrations are increased at each  level in the food chain.
This process of increasing pollutant concentration through the food chain is
                       called biomagnification.
                           the top predators in  a food chain, such as'
                       lake trout, coho and chinook salmon, and fish-
                       eating gulls, herons, and  bald eagles, may accu-
                       mulate concentrations of a toxic chemical high
                       enough to cause serious deformities or death or to
                       impair their ability to reproduce. The concentra-
                       tion of some  chemicals in the fatty tissues of top
                       predators can be millions of times higher than the
                       concentration in the surrounding water.
                           Eggs of fish-eating birds often contain some
                       of the highest concentrations of toxic chemicals.
                       Thus, the first apparent effects of a toxic chemical
                       in a waterbody may be unhatched eggs or dead
                       or malformed chicks. Scientists monitor colonies of
                       gulls and other aquatic birds because these effects
                       can serve as early warning signs of a growing
                       toxic chemical problem.
                           Biomagnification of pollutants in the food
                       chain is also a significant  concern for human
                       health. To protect their residents from these risks,
                       States issue fish consumption advisories or
                       warnings about eating certain types of fish.

children, pregnant women, or nurs-
ing mothers), specific fish species
that concentrate toxic pollutants in
their flesh, or larger fish within a
species that may have accumulated
higher concentrations of a pollutant
over a longer lifetime than a smaller
(i.e., younger) fish.
    EPA evaluates the national
extent of toxic contamination in fish
and shellfish by counting the total
number of waterbodies with con-
sumption advisories in effect. EPA
used its database, the National List-
ing of Fish Consumption Advisories,
to tabulate the number of State
advisories. EPA built the database to
centralize fish consumption advisory
information separately maintained in
various State agencies and the U.S.
Fish and Wildlife Service. EPA con-
tacted each State in the fall of 1994
to update the database.
    The 1994 EPA National Listing
of Fish Consumption Advisories
listed 1,531  advisories in effect in 47
States, the District of Columbia, and
American Samoa (Figure 7-1). The
database counts one advisory per
waterbody,  regardless of the num-
ber of species affected and the
number of toxic pollutants detected
at dangerous concentrations in fish
sampled within a waterbody (see
Appendix E, Table E-1, for individual
State data).
    EPA cannot identify States with
a high proportion of toxic contami-
nation based solely on the number
of fish consumption advisories
issued by each State. National statis-
tics on advisories are difficult to
interpret because the intensity and
coverage of State  monitoring pro-
grams vary widely from State to
State and each State can set its own
criteria for issuing advisories. Simply
comparing the total number of fish
advisories in each State unfairly
penalizes States with superior
toxicants monitoring programs and
strict criteria for issuing consump-
tion warnings.
    The EPA has advocated consis-
tent criteria and methods for issuing

Note: States that perform routine fish tissue analysis (such as the Great Lakes States) will
     detect more cases of fish contamination and issue more advisories than States with less
     rigorous fish sampling programs. In many cases, the States with the most fish advisories
     support the best monitoring programs for measuring toxic contamination in fish, and
     their water quality is no worse than the water quality in other States.

ever, it will be several years before
the States implement consistent
methods and criteria and establish a

expects the States to issue more
advisories as they sample more sites
and detect contamination that pre-

    Mercury, PCBs, chlordane,
dioxins, and DDT  (with its byprod-
ucts) caused almost all of the fish
consumption advisories in effect in
1994 (Figure 7-2). EPA and the
States have banned or restricted the
use of PCBs, chlordane, and DDT
for over a decade, yet these chlori-
nated hydrocarbon compounds   -
persist in sediments and fish tissues
and still threaten public health.

monitoring programs, they found
elevated concentrations of mercury
in fish inhabiting remote lakes that
were previously considered unpol-
luted. States from Wisconsin to
Florida reported widespread mer-
cury contamination in fish collected
primarily from  lakes. The source of
the mercury contamination is diffi-
cult to identify because mercury
naturally occurs in soils and rock
formations. Natural processes, such
as weathering of mercury deposits,
release some mercury into surface
waters. However, resource managers
believe that human activities have
accelerated the rate at which
mercury accumulates in our waters
and enters the food web.
    Air pollution may be the most
significant source of mercury con-
tamination in surface waters and
fish. According to EPA's Toxics
Release Inventory, almost all of the
mercury released by permitted pol-
luters enters the air;  industries and
waste treatment plants discharge
very little mercury directly into sur-
face waters. Emissions from waste
incinerators, coal-fired plants, smelt-
ers, and mining operations may
carry mercury many miles to remote
watersheds (see sidebar, page 132).
Other potential sources of mercury
contamination include slag heaps
from metal mines and land-di:sturb-
ing activities that may mobilize
natural mercury deposits, such as
channelization, reservoir construc-
tion, and drainage projects.
    Air emissions may further aggra-
vate mercury contamination by
generating acid precipitation that
increases acidity in lakes. The accu-
mulation of mercury in fish appears
to correlate with acidity in a
waterbody. Slightly acidic conditions
promote the chemical conversion of
mercury to a methylated form that

                                                         Chapter Seven Public Health and Aquatic Life Concerns  131
is more readily available for uptake
and accumulation in fish. States,
such as Louisiana, are using this
correlation to target waterbodies
with acidic pH and  low buffering
capacity for mercury sampling in
fish.
    EPA sponsored a symposium to
gather and exchange the available
information on mercury contamina-
tion in fish. The National  Forum on
Mercury in Fish met in September
of 1994 to examine fate and trans-
port of mercury in the environment
and methods to assess the health
effects of mercury.
    The EPA Fish Consumption
Advisory Database does not identify
sources of contamination in fish.
Sources of contamination are diffi-
cult to isolate because migratory fish
may be exposed to toxic pollutants
in the sediments and water column
or may ingest toxic contaminants
concentrated in prey miles from the
sampling areas where they  are col-
lected. Furthermore, migratory or
resident fish may  be exposed to
toxic pollutants that have been
transported great distances  from
where they originated.

Bacterial and Viral
Contamination

    Waterborne viral and bacterial
pollutants may also cause serious
human illness and death. People
can contract infectious hepatitis,
gastroenteritis, dysentery, and
cholera from waters receiving inad-
equately treated sewage. Bacteria
and viruses may enter human
systems through contact with
contaminated swimming  and bath-
ing waters or through ingestion of
contaminated drinking water or
shellfish.
Shellfish Contamination

    Contaminated shellfish pose a
public health risk particularly to
those who consume raw shellfish.
Shellfish, such as oysters, clams, and
mussels, extract their food (plank-
ton) by filtering water over their
gills. In contaminated waters, shell-
fish accumulate bacteria and viruses
on their gills and mantle and within
their digestive systems. If shellfish
grown in contaminated waters are
not cooked properly, consumers
may ingest live bacteria and  viruses.
    To protect public health, the
U.S. Food and Drug Administration
administers the National Shellfish
Sanitation Program (NSSP). The
NSSP establishes minimum monitor-
ing requirements and criteria for
State shellfish programs that want
to participate in  interstate com-
merce of shellfish. States cannot sell
shellfish outside of their State
boundaries unless their shellfish
sanitation program follows NSSP
protocols. Coastal States routinely
monitor shellfish harvesting areas for
bacteria! contamination and  restrict
shellfish harvests in contaminated
waters. Most often, States measure
concentrations of fecal  coliform
bacteria such as  Escherichia colt,
which are nonpathogenic bacteria
that populate human digestive sys-
tems and occur in fecal wastes.
Their presence in water samples is
an indicator of sewage contamina-
tion that may pose a human health
risk from pathogenic viruses  and
bacteria. Fecal bacteria, however,
may exceed criteria even when no
human sewage is present because
birds and nonhuman mammals also
excrete them.
    The NSSP recognizes three
types of shellfish harvesting
restrictions:
    In 1990, EPA began develop-
ing technical guidance to help
the States adopt consistent criteria
and methods for issuing fish con-
sumption'advisories. The guid-
ance consists of four volumes:

    •  Volume I:  Fish Sampling
and Analysis recommends
standard  methods for sampling
and analyzing contaminants in
fish tissue.

    •  Volume II:  Risk Assessment
and Fish Consumption Limits
suggests  protocols for selecting
criteria for unsafe concentrations
of contaminants in fish.

    •  Volume III: Risk Manage-
ment suggests protocols for deter-
mining if the health risk justifies
issuing an advisory.

    •  Volume IV: Risk Communi-
cation recommends methods for
informing the public about fish
consumption advisories.

    EPA published the first edition
of Volume I in 1993 and released
a second edition in  the Fall of
1995. Volume II was issued in
1994. Volume III is due to be
released in 1996, and Volume IV
was released in the  Spring of
1995. EPA presented the first two
volumes to State, Tribal, and
Regional  managers at two work-
shops in  1994.

    Air  Pollution  impacts on Water Quality

Pollutants are released into the air from man-made or natural
sources. Man-made sources include industrial stacks, municipal incin-
erators, pesticide applications, and vehicle exhaust. Natural sources
can be volcanic eruptions, windblown gases and particles from forest
fires, windblown dust and soil particles, and sea spray.

Pollutants released to the air are carried by continental wind patterns
away from their areas of origin. Depending on weather conditions
and the chemical and physical properties of the pollutants, they can
be carried varying distances from their sources and can undergo
physical and chemical changes as they travel.

Air pollutants are deposited  to the earth or directly to waterbodies by
either wet or dry deposition. Wet deposition occurs when pollutants
are removed from the air by falling rain or snow. Dry deposition
occurs when particles settle out of the air by gravity  or when gases
are transferred  directly from the air into water. Air pollutants that
deposit on land can  be  carried into a waterbody by stormwater
runoff.                                                         ,

•  Prohibited Waters violate criteria
consistently; therefore, shellfish
cannot be harvested at any time.

•  Restricted Waters may be har-
vested if the shellfish are transferred
to clean  waters to reduce concen-
trations of bacteria.

•  Conditionally Approved Waters
temporarily exceed bacteriological
criteria following predictable events
(such as a storm). Shellfish from
these waters  may be harvested
when  criteria are met.

    The  size of waters with shellfish
harvesting restrictions does not
equate with the size of polluted
estuarine waters because States
sometimes restrict harvesting  in
clean waters. The NSSP requires
that a State prohibit shellfishing in
clean waters  if the State cannot
monitor a waterbody on a routine
schedule that ensures rapid detec-
tion of unsafe conditions. As a
result, funding for monitoring activi-
ties can  raise or lower the size of
waters classified as "prohibited"
even if water quality does not
change.  Georgia,  for example,
reported that funding for a new
laboratory position during 1992 and
1993 restored shellfishing to clean
waters previously  classified as "pro-
hibited" due to a lack of monitor-
ing.
    As a preventive measure, the
States also automatically prohibit
the harvest of shellfish near marinas
and pipes that discharge waste-
water. These closures protect the
public from accidental releases of
contaminated wastewater due to
treatment plant malfunctions or
overflows during severe weather.
The preventive closures apply to
marinas  because fecal bacteria con-
centrations may increase during
high use periods, such as weekends.
The States prohibit shellfishing in
these waters even though these
waters may not contain harmful
concentrations of fecal bacteria
most of the time.
    Despite these  drawbacks, the
size of waters with shellfishing
restrictions is our most direct mea-
sure of impacts on the shellfishing
resource.  However, only 16 of the
27 coastal States and Territories
reported the size of their estuarine
waters affected by shellfish harvest-
ing restrictions (Table 7-1). With so

few States reporting numerical data,
EPA cannot summarize the national
scope of shellfish harvesting
conditions at this time. The National
Oceanic and Atmospheric Adminis-
tration is developing a database to
track State restrictions that should
provide a more complete profile of
shellfishing conditions in the future.
    The reporting States prohibit,
restrict, or conditionally approve
shellfish harvesting in 6,052 square
miles of estuarine waters. About
one-third  of these waters are  condi-
tionally approved, so the public can
harvest shellfish from these waters
when the State lifts temporary
closures. For comparison, 12  States
reported that almost 8,000 square
miles of estuarine waters are fully
approved for harvesting shellfish at
all times (Appendix E, Table E-3,
contains individual State data).
    Only five States reported  the
size of shellfish restrictions caused
by specific sources of pathogen
indicators .(Figure 7-3). Other States
provided narrative information
about sources degrading shellfish
waters.

• Georgia reported that the State
prohibits shellfish harvesting in 362
square miles of its waters. Harvest-
ing is prohibited in 280 square miles
of potential shellfish waters due to a
lack of data. Most of Georgia's
other restricted areas are closed
because of their proximity to indus-
trial discharge pipes and marinas.

• Louisiana reported that sewage
treatment plant upgrades expanded
areas open for shellfish harvesting,
but the size of healthy oyster
growth zones still decreased
because of nonpoint source pollu-
tion, sewage from camps, saltwater
intrusion,  and  marsh erosion.

•  Maryland reported that nonpoint
source runoff is the most pervasive  .
source of bacterial contamination in
the State's shellfish waters. Other
sources include boating activity,
agricultural runoff, seafood process-
ing, and combined sewer overflows.

•  New Hampshire reported that

ing into coastal waters. The State
plans to upgrade the four remaining
sewage plants  discharging into
coastal waters  and begin addressing

Drinking Water
Concerns

    After decades of concerted
effort, Americans can generally turn
on their taps without worry about
the quality of the drinking water
that flows out. Yet many important
questions about  drinking water
safety remain unsettled. The EPA
reviewed available information con-
cerning the safety of public water
supplies and discovered that there
are pockets of serious trouble, gaps
in information, and emerging
threats to drinking water safety.
    Rising consumer awareness of
pollution and other environmental
problems has raised concerns about
drinking water safety:

•  A 1993 survey commissioned by
the National Geographic Society
found that nearly one-third of
Americans  believe that their drinking
water is either contaminated or  may
become contaminated  in  the future.
• The rising sales of bottled water,
now exceeding 2.2 billion gallons
annually with a wholesale value
estimated at over $2.4 billion, bear
testimony to consumer concerns
over tap water quality.

• Consumer and environmental
groups have lobbied for improved
public information and education
on drinking water safety issues,
including monitoring, source water
protection, and drinking water treat-
ment.

    There are approximately 57,600
Community Water Systems that
provide year-round drinking water
to the homes of  approximately 244
million Americans (roughly 90% of
all U.S. households) (Figure 7-4).
The  EPA also  regulates over 140,000
additional systems that provide
year-round drinking water to people
at schools, roadside rest stops, and
other facilities. These community
and  noncommunity systems draw
water from surface water or ground
water and are subject to the drink-
ing water regulations set forth
under the Safe Drinking Water Act.
Under this Act, water suppliers are
required to conduct tests  to deter-
mine whether drinking water quality
meets safety standards (Figure 7-5).
The  suppliers must then report the
results to the State agency respon-
sible for drinking water protection.

Community Water Systems

    The EPA estimates that almost
10% of Community Water Systems
have experienced one or more vio-
lations of Federal safety standards in
the past few years. Most of the
violations relate to actual

 National Primary Drinking
 Water Regulations

    The EPA has promulgated
 National Primary Drinking Water
 Regulations (NPDWRs) covering 84 '
 contaminants. These contaminants
 include 21 volatile organic corn-
 pounds, 35 synthetic organic com-
 pounds, 18 inorganic compounds,
 three radionuclides, five microorgan-
 isms, a water quality indicator, and
 a disinfection byproduct. Most of
 these regulations relate to contami-
 nants that may be introduced into
 source water due to land use prac-
 tices near the water supply. The
 NPDWRs provide enforceable stan-
 dards that protect the quality of the
 Nation's drinking water.

 Drinking Water Quality
 and Microbiological
 Contaminants

    Thanks to basic drinking water
 disinfection, drinking water in the
 United States is virtually free of cer-
 tain diseases.  Cholera and typhoid
 fever, which afflict many people in
 other nations, have been effectively
 removed from our drinking water
 supplies. However, Americans are
 not free of drinking water problems
 posed by microbiological contami-
 nants. Many of the following prob-
 lems were due to microbiological
 contamination of source waters.

•  In 1993, an estimated 403,000
 residents of Milwaukee became ill
from an outbreak of the common
waterborne protozoan, Crypto-
sporidium.

•  Drinking water contamination
was not uncommon in 1993 follow-
ing the summer floods in the
midwestern and southern States.

    A total of 16,294 Community
Water Systems  (nearly 29%) experi-
enced violations of NPDWRs in
1992. Approximately 32% of Com-
munity Water Systems experienced
violations of NPDWRs in 1993. Vio-
lations occurred in virtually every
State  and  influenced the water qual-
ity of approximately 63 million
people.  Most of the violations
affected very small systems serving
between 25 and 500 people. The
following violations of health-based
standards  occurred in 1993.

• The drinking water supplied to
nearly 11% of the population served
by Community Water Systems
(26.5 million people) violated
health-based standards.

• 1,516 Community Water Systems
experienced violations for inorganic
contaminants. These violations
affected 7.2 million  people.

• 852 Community  Water Systems
experienced violations for organic
contaminants. These violations
affected 8.7 million  people.

• 576 Community  Water Systems
experienced violations for radiologi-
cal contaminants. These violations
affected 1.3 million  people.

• 574 Community  Water Systems
experienced serious, frequent, or
persistent noncompliance with
chemical or radiological  require-
ments (11 % violated health-based
standards for nitrate, 3% for fluo-
ride, and 3% for radium).

• 12 Community Water Systems
and 22 Noncommunity  Water
Systems experienced health-based
violations related to trichloroethyl-
ene, a carcinogen used in textiles,
adhesives, and metal degreasers.

• Other organic chemicals that
caused health-based violations in
drinking water supplies include
atrazine,  ethylene dibromide, and
benzene.

    Except for naturally  occurring
contaminants such as fluoride and
radium, all of the violations
mentioned above resulted from
land-use  practices near the affected
water supplies.
The Benefits and Costs
of Keeping Our Drinkinq
Water Safe

    As with many other environ-
mental concerns, it is difficult to
quantify the benefits of maintaining
safe drinking water. As more water
supply systems meet the standards
set forth in the Act, EPA estimates
that the following national health
benefits may be realized.

• Reduced lead exposure for
approximately 50 million Americans,
and protection of approximately
200,000 children from dangerous
levels of lead in their blood

• Prevention of more than 100,000
cases of gastrointestinal illnesses

• Reduced exposure to dozens of
toxic contaminants that may affect
the drinking water of millions of
Americans

• Avoidance of more than  100
excess cancer cases each year from
reduced exposure to carcinogenic
contaminants in drinking water.

    The costs of compliance with
the Safe Drinking Water Act have
also been estimated. These  esti-
mates are based on appraisals of the
number of water supply systems
that will need to invest in treatment
to meet drinking water standards
and anticipated treatment costs.

• The national  costs attributable to
compliance with existing drinking
water safety regulations are
estimated to be $1.4 billion
annually.

•  The projected effect on house--
hold water bills ranges from an
increase of 25 cents per month for
systems serving 1 million or more
households to $12 per month for
systems serving 100 or fewer
households.

•  Greater than two-thirds of the
estimated costs relate to control of
microbiological contaminants and
lead in drinking water.

•  The projected effect of monitor-
ing requirements on household
water bills ranges from an average
of 1  cent to 35 cents per month for
90% of American households.

•  For small Community Water Sys-
tems, however, the projected effect
of monitoring requirements could
exceed $10 per month.

Protecting Drinking Water
Sources

    Land use in both urban and
rural settings may pose chemical
and  microbiological threats to cur-
rent and future drinking water sup-
plies. Urban uses of land  have more
than tripled since the 1950s, rising
from 18.3 million acres to 56.6
million acres. Population growth
and  the expansion of urban land
use are likely to pose new risks of
contamination in areas that may not
have been at risk before.  In  rural
areas, the use of agricultural chemi-
cals has doubled since the 1960s.
Many States list agriculture as the
leading source of water quality im-
pairment in our Nation's  rivers.
    In a 1988 survey of surface
water utilities and State drinking
water agencies, the American Water
Works Association investigated the
relationship between land use and
water treatment. Their results sug-
gest that more advanced water
treatment practices are necessary
for source waters derived from wa-
tersheds where urban or agricultural
land use practices predominate.
    Virtually all groups interested in
drinking water safety promote
stronger efforts to prevent pollution
from entering drinking water
sources rather than relying solely on
water treatment to reduce health
threats. The EPA encourages source
water protection activities geared at
protecting surface water and
ground water that is used for drink-
ing water supply.


Recreational Restrictions

    State reporting on recreational
restrictions, such as beach closures,
is often incomplete because most
State agencies rely on local health
departments to voluntarily monitor
and report beach closures. Most
State agencies that prepare the
305(b) reports do not have access
to an  inventory of beach closures.
The information obtained varies in
quality because health departments
that monitor infrequently will detect
fewer bacteria violations than health
departments with rigorous beach
monitoring schedules.
    Twelve States reported that
there were no contact recreation
restrictions reported to them during
the 1994 reporting cycle, but one
State mentioned that unreported
closures could exist. Twenty-two
States identified 374  sites where
recreation was restricted at least
once during the reporting cycle
(Appendix E, Table E-6, contains
individual State data). Local health
departments closed many of these

                                     Concerns       	

                                         Many native aquatic organisms
                                     are more sensitive than  humans to
                                     toxic pollutants. In severe cases of
                                     contamination, toxic pollutants kill
                                     all aquatic life;  in less severe cases,
                                     toxic pollutants eliminate some spe-
                                     cies from the aquatic community.
                                     The aquatic system deteriorates as
                                     toxic contaminants poison aquatic
                                     organisms (including fish, shellfish,
                                     benthic organisms, and plants),
                                     increase their susceptibility to dis-
                                     ease, interfere with their reproduc-
                                     tion, or reduce the viability of their
                                     young. Toxic pollutants also disrupt
                                     the chemical and physical balance
                                     in an aquatic ecosystem and indi-
                                     rectly cause mortality. Chapter 1
                                     provides additional information
                                     about toxic pollutants.
                                         Low oxygen concentrations,
                                     excessive temperatures,  or high or
                                     low acidity can have more devastat-
                                     ing impacts on aquatic  communities
than toxic pollutants. Organic
pollutants (such as sewage, manure,
food processing wastes, and lawn
clippings) impose a biochemical
oxygen demand (BOD) on receiving
waters because bacteria consume
oxygen as they decompose organic
wastes. Nutrients also may indirectly
deplete oxygen concentrations by
feeding algal blooms (see Chapter 1
for a full  discussion of dissolved
oxygen depletion).
    Acidity (the concentration of
hydrogen ions measured as pH)
drives many chemical reactions in
living organisms. Many biological
processes (such as reproduction)
cannot function in either acidic (low
pH) or alkaline (high pH) waters.
Acidic conditions also aggravate
toxic contamination problems
because sediments release toxicants
in acidic  waters. Common sources
of sulfuric acid, and, to a lesser
extent, nitric acid, include mine
drainage, runoff from mine tailings,
and atmospheric deposition.
    Alkaline conditions (high  pH)
may result indirectly from inputs of
nutrients that induce excessive algal
activity. In order to fuel photosyn-
thesis,  rapidly expanding algae
populations may break down car-
bonate compounds after they con-
sume all  of the carbon dioxide avail-
able in the water column. As the
algae convert carbonates to carbon
dioxide, hydroxyl groups (OH~ ions)
are released into the water column,
raising the pH. Alkaline conditions
(high pH) harm gill membranes on
fish and other aquatic organisms.
The pH may swing back down dur-
ing the night as the algae halt pho-
tosynthesis and stop scavenging
carbon dioxide from carbonates. At
night, the algae also continue 1:o
respire, which returns carbon

dioxide into the water column that
can bind up the hydroxyl groups
and lower pH. Such fluctuations in
pH severely stress aquatic organ-
isms.
    Human activities on shore can
aggravate physical and chemical
conditions in waterbodies. The
States report growing concern over
instream impacts from  removal of
shoreline vegetation. Shoreline veg-
etation shades streams from exces-
sive heat and binds shoreline soils
together, which prevents sediment
from entering the water column.


Fish Kills Caused
by Pollution

    The number of fish kills provides
a limited indication of pollutant
impacts on aquatic life because fish
kills do not always result from pollu-
tion. Both natural conditions (such
as drought, low flow, and warm
water temperatures) and pollution
can deplete dissolved oxygen in a
waterbody and suffocate fish. Pollut-
ants may also weaken fish and make
them more susceptible to natural
stressors, such as disease. In many
cases, investigators cannot deter-
mine if pollution, natural causes, or
both caused  a fish kill because there
is  little evidence at the site of the
fish kill. The exact location of the
fish kill may be a mystery because
currents can  carry fish downstream
from the source, further complicat-
ing the investigation.
    Forty States, Tribes, Commis-
sions, and Territories submitted
numerical data about fish kills in
their 1994 Section 305(b) reports
(Appendix E, Table E-7a, contains
individual State data). Two Tribes,
the District of Columbia, the
Delaware River Basin Commission,
and New Hampshire stated that
there were no fish kill incidents re-
ported in their waters during 1992
and 1993. Thirty-five States and one
Territory reported that pollution
caused 737 fish kills in their waters
(Figure 7-6). This figure underesti-
mates the real number of fish kills
in the Nation because 15 States
did not provide fish kill data and
fish kills in remote areas may not be
detected or reported to State fish
and wildlife officials.
    EPA summarized the number
of kills due to pollution, natural
conditions, hydrologic modification,

ambiguous causes, and unknown
causes. EPA used the following
criteria to classify the cause of fish
kills:

• Pollution - the State clearly iden-
tified a specific pollutant responsible
for the kill or clearly stated that
oxygen was depleted by pollutants.

• Natural Conditions - the State
used the term "natural" to describe
the kill.

• Ambiguous Causes - the State
attributed the kill to low oxygen
concentrations, disease, red tides,
algal blooms, or thermal shock and
did not specify whether pollution
contributed to these problems or
not.

• Hydrologic Modifications - the
State identified dam construction,
dewatering, channelization, or
drawdown as the cause of the kill.

• Dumping - throwing unwanted
fish into waterbodies.

• Unknown - the State did riot
identify a cause of the kill.

    EPA classified 1,454 total fish
kills in 29 States that reported both
the total number of fish kills and the
number due to pollution (Figure
7-7).  Pollution clearly caused about
one-third of the fish kills. Natural
conditions caused  about one-fifth of
the fish kills. Almost half of the fish
kills were due to unknown or
ambiguous causes.
    The States reported that toxic
pollutants caused more than half
(55%) of the fish kills attributed to
human activities (Figure 7-8).

 herbicides (weed killers and defoli-
 ants), oil and gasoline products,
'chlorine, ammonia, metals, and
 unspecified hazardous substances.
 Pesticides were the most frequently
 identified toxic pollutant causing
 fish kills (Figure 7-9). Many pesticide
 kills occurred on small private lakes
 and ponds and impacted few fish,
 but several pesticide releases  killed
 over 10,000 fish per incident. The
 States reported that agricultural
 application and runoff caused most
 fish kills from pesticides, but the
 States also reported that golf course
 maintenance and mosquito abate-
 ment projects released pesticides
 and  killed fish. Historically, the  most
 devastating pesticide kills have
 resulted from train derailments
 releasing highly concentrated pesti-
 cides and herbicides into water-
 bodies.
     Following pesticides, oil and
 gasoline products  (including  jet fuel)
 and chlorine caused many fish  kills.
 The States reported that oil and
 gasoline products  entered water-
 bodies from traffic accidents, airport
 runoff, and leaking storage facilities.
 The States reported that chlorine
 from drinking water treatment
 plants, sewage plants, and swim-
 ming pools entered waterbodies in
 lethal concentrations. The States
 also reported that less common
 toxic pollutants caused fish kills,
 including road tar, deicing chemi-
 cals used at airports, and fire sup-
 pression foam used at the scene of
 traffic accidents.
      The States reported that oxy-
 gen-depleting substances caused
 20% of the fish kills attributed to
 human activities.  In waterbodies,
 bacteria consume oxygen when
 they decompose substances con-
 taining organic plant, fish, or animal
matter. Oxygen-depleting sub-
stances include food products and
byproducts (such as molasses, bad
milk, and seafood processing
waste), agricultural feed, sewage,
manure,  rendering wastes, and
other industrial wastes that contain
plant or wood fibers. Sewage and
manure can also contain high con-
centrations of ammonia, which is
toxic to fish and other aquatic
organisms. The  States reported that
sewage contributed to 5% of the
fish kills due to pollution, and
manure from  animal and poultry
operations contributed to 4% of the
kills due to pollution.
    Thirty-five States listed sources
of pollution causing fish kills (Figure
7-10). These States identified agri-
culture as the leading source of fish
kills. Agricultural runoff may contain
manure  and fertilizer, in addition to
pesticides and herbicides. Sewage
treatment plants followed agricul-
ture as the leading source of fish
kills. Sewage treatment plants also
release ammonia, nutrients, and
oxygen-depleting substances into
receiving waters. Sewage treatment
plants also cause fish kills by dis-
charging overchlorinated effluent.
The other leading sources of fish
kills included  industry; spills and
 leaks from storage tanks, trucks,
 barges, trains, and pipelines;
 nonagricultural applications of pesti-
 cides; general runoff; and drinking
water systems.  Less common
 sources  of fish kills included swim-
 ming pools, petroleum activities,
 land disposal of wastes, bridge
 demolition, fountain maintenance,
 and dam releases.
     The summary data on fish kills
 obscure important variations in the
 number of fish killed and the value
 of the species affected during

                                     summary data cannot distinguish a
                                     fish kill that affected 10 fish from a
                                     fish kill that affected several hundred
                                     thousand fish. Numbers of fish killed
                                     cannot measure the value of a fish
                                     kill because consumers and anglers
                                     value some fish species more highly
                                     than others, and we do not under-
                                     stand the value of different species
                                     in the ecosystem. The States re-
                                     ported that many desirable fish
                                     species were killed by pollution,
                                     including trout, salmon, perch, mul-

                                     Sediment  Contamination

                                        Many waterborne toxic pollut-
                                    ants settle to the bottom and parti-
                                    tion between the sediment material
                                    and the solution in the interstitial
                                    water between the sediment par-
                                    ticles. Bacteria  degrade some
                                    toxicants in sedirhents, but many
                                    toxic contaminants (such as metals
    and PCBs) persist in sediments for
    many years after the original toxic
    source has been eliminated. Disrup-
    tion of contaminated sediments or
    natural interactions may reintroduce
    toxicants into the water column for
    decades.
        Dredging contaminated sedi-
    ments may also reintroduce toxi-
    cants into the water column and
    food web. Due to these impacts,
    sediment contamination can
    obstruct maintenance dredging of
    harbors and navigation channels.
    Dredge spoil disposal methods
    (such as open water dumping,
    spreading  on "reclaimed" lands,
    and diked  containment areas) may
    also create new aquatic life threats.
        Currently, no national criteria
    are in effect that define harmful
    concentrations of pollutants in sedi-
    ment. However, EPA released draft
    sediment criteria for five pollutants
    (endrin, dieldrin, phenanthrene,
    fluoranthene, and acenaphthene) in
    January of  1994 for public comment
    and plans to publish final criteria for
                                               Sources Associated with Fish Kills

the five toxicants in 1996 after
responding to final comments. An
approach for assessing metals con-
tamination in sediments was pre-
sented to the EPA Science Advisory
Board in January of 1995. The
approach for determining metals
toxicity in sediments received a very
favorable review.
    In  1994, 23 States reported
incidents of sediment contamination
in their 305(b) reports (see Appen-
dix E, Table E-10, for individual
State data). Several States preferred
not to list contaminated sites until
EPA publishes national criteria for
screening  sediment data. Other
States  lack the analytical tools and
resources to conduct extensive
sediment sampling and analysis.
Therefore, the following discussion
probably understates the extent of
sediment contamination in the
Nation's surface waters.
    Twenty-two States  listed 641
separate sites with contaminated
sediments and identified pollutants
detected in sediments.  These States
most frequently listed metals (e.g.,
mercury, cadmium, and zinc), PCBs,
DDT (and its byproducts), chlor-
dane,  polyaromatic hydrocarbons
(PAHs), and other priority organic
toxic chemicals. These States also
identified  industrial and municipal
discharges (past and present), land-
fills, resource extraction, abandoned
hazardous waste disposal sites, and
combined sewer overflows as the
primary sources of sediment
contamination.
     EPA develops guidance and
information sources to  provide
States with better tools for assessing
and managing sediment contamina-
tion, including
•  A compendium of sediment
assessment methods (Fall 1992)

•  Draft Sediment Quality Criteria
for Non-ionic Organics (October
1993)

•  National Sediment  Inventory
(Report to Congress, Spring 1996)
     -  Evaluation of Contaminated
       Sediment Sites  (Fall 1995)
     -  Point Sources Inventory
       (Fall 1995)
     -  Nonpoint Sources Inventory
       (Fall 1996)

•  Sediment Remediation Methods
(Spring 1993)

•  EPA's Sediment Management
Strategy will focus the Agency's
resources on preventing, remediat-
ing,  and managing disposal of
dredged contaminated sediments
(Summer 1994)

•  A testing manual for  evaluating
sediment disposal in inland waters
under  Section 404 of  the Clean
Water  Act (Spring 1994)

•  Guidance documents describing
methods for conducting acute toxic-
ity tests, chronic toxicity tests,  and
bioaccumulation tests for sediments
(Fall 1993)

•  Methods for deriving sediment
quality criteria for heavy metals
(late 1997).

Total Waters Affected
by Toxic Pollutants

    Responding to public concern
about toxic pollutants, EPA
requested that States track the over-
all extent of toxic contamination in
their surface waters.  Forty-two
States and Tribes reported the size
of waters surveyed for toxicants
(either in the water column, sedi-
ments, or aquatic organisms) and
the total waters found to contain
elevated concentrations of toxic
pollutants (see Figure 7-11 and
Appendix E, Table E-11, for indi-
vidual State data).
    Thirty-six States and Tribes
reported that they surveyed
toxicants (primarily in the water
column) in 160,335 miles of rivers
and streams. These States and
Tribes surveyed only 5% of the
Nation's 3.5 million river miles for
toxic contamination. The States and
Tribes detected elevated concentra-
tions of toxicants in 25% of the
surveyed rivers and streams (Figure
7-12).

acres of lakes, reservoirs, and ponds.
The surveyed acres represent 18%
of the Nation's 40.8 million lake
acres. The States and Tribes found
elevated concentrations of toxicants
in 29% of the sampled lake acres.
    Seventeen coastal States
sampled toxicants in 23% of the
Nation's estuarine waters. These
States detected elevated toxic con-
centrations in 26% of the 7,865
square miles of estuarine waters that
they sampled.
    Only three States and the Virgin
Islands reportedly surveyed toxicants

        not be applied nationally because
        the States surveyed less than 1 % of
        the Nation's coastal waters (exclud-

           Five States reported that they
        surveyed most of their Great Lakes'
        shoreline for toxicants (primarily in

                                          EPA's  Source Water  Protection
                                          Initiative
                                    Americans have long enjoyed
                                the luxury of safe, affordable drink-
                                ing water. A rising awareness of
                                water pollution incidents, however,
                                has caused people to be concerned
                                about drinking water quality. Many
                                communities have recognized that
                                preventing the pollution of lakes,
                                rivers, streams, and ground water is
                                the key to ensuring the long-term
                                safety of drinking water. This
                                common sense approach is known
                                as source water protection.
                                    The Safe Drinking Water Act
                                emphasizes monitoring and treat-
                                ment to protect drinking water
                                safety. However, protection based
                                on monitoring and treatment alone
                                is not sufficient. Nearly all groups
                                interested in drinking water safety
                                see a need for stronger efforts to
                                prevent pollution from entering
                                drinking water sources rather than
                                relying solely on water treatment to
                                reduce health threats.
                                    The EPA encourages this preven-
                                tion-oriented approach and is
                                actively promoting the development
                                of grass roots source water protec-
                                tion activities. As part of the  Source
                                Water Protection Initiative, EPA
                                hopes to:
•  Restore the public's rights and
responsibilities to protect their drink-
ing water

•  Raise public confidence in the
safety and quality of their drinking
water supply

•  Reduce the costs of providing
safe drinking water.

Wellhead  Protection
Programs

    Many States and communities
are currently promoting source
water protection in Wellhead
Protection (WHP) programs. The
1986 Amendments to the Safe
Drinking Water Act established the
Wellhead Protection Program to aid
communities in protecting their
drinking water quality. Through
wellhead protection, communities
identify the land areas that contrib-
ute ground water to public water
supply wells. They then develop
plans to manage the potential
sources of contamination in those
vulnerable areas, thereby reducing
the likelihood of polluting the drink-
ing water source.

By the end of December 1 994,
a total of 37 States and Territories
had EPA-approved WHP Programs
in place. In addition, thousands of
local WHP initiatives have been
undertaken in communities across
the Nation. As of 1 993, approxi-
mately 3,800 communities that are
dependent on ground water for
drinking water had complete WHP
programs.
Expanded Source
Water Protection
Goals
The idea of wellhead protection
can apply to surface water supplies
as well. The EPA is encouraging
stronger watershed protection
programs, through approaches
available under the Federal Clean
Water Act, to protect surface waters
used for drinking water supplies.
Source water protection, for both
ground water and surface water,
may offer significant advantages to
both drinking water purveyors and
consumers.
The EPA is planning a National
Source Water Protection Workshop
in 1 996. This workshop will provide

/ ',*'"'*
SH*;






communities with the tools and
information needed to establish
source water protection programs.
The workshop will be televised and
will target communities that have
delineated their source water pro-
tection areas and carried out source
identification. The workshop will
also assist communities in moving
toward source management.
The EPA has also set the follow-
ing interim and long-term source
water protection goals:
• By 1997, establish a core network
of 1 0,000 communities with active
and comprehensive local WHP
programs in place.

• By 1 997, incorporate source
water protection and source
management as priority objectives
in projects requiring financial assis-
tance from other Federal programs
• By 1 997, begin to expand source
water protection approaches to
communities reliant on surface
water for drinking water.
• By 2005, have 50% of all com-
munity water supplies covered by
active and comprehensive local
source water protection programs.

                                      In the late 1980s the Public
                                   Health Service (PHS), working with
                                   over 300 government and non-
                                   government organizations, began
                                   developing Healthy People 2000, a
                                   set of public health goals and objec-
                                   tives for the year 2000. This initia-
                                   tive was a logical extension of their
                                   previous efforts, the 7990 Health

Water Objectives
and Progress

    The first of the three water-
related objectives calls for a reduc-
tion in the number of outbreaks of
waterborne diseases from infectious
agents and chemical poisonings in
drinking water to no more than 11
per year by the year 2000. The
numbers of these rare events have
fluctuated considerably since 1988
when 16 outbreaks were reported
(see Figure 1). While public health
officials work to maintain and
improve the quality of drinking
water, variations in physicians'
reports to State Health Departments
and the availability of resources to
confirm the outbreak as waterborne
hamper the monitoring of these
outbreaks.
    The second objective calls for
an increase in the percentage of the
population whose drinking water
supply meets the Safe Drinking
Water Act regulations. The data
source for this objective is EPA's
Federal Reporting Data System
(FRDS). The proportions reported
since the 1988 baseline appear to
have changed little, but as Figure 2
indicates, the quantity and
stringency of testing standards have
continued to  increase.
    Third, Healthy People 2000
monitors the  quality of surface
water using EPA's National Water
Quality Inventory. As originally

 Disease Registry, and the National
 Center for Health Statistics, all of the
 Centers for Disease Control and
 Prevention. The National Institute of
 Health's National Institute of Envi-
 ronmental Health Sciences also
 shares the responsibility of monitor-
 ing these  objectives. There has been
 extensive  cooperation and data
 sharing with EPA on the beneficial
 use objective, which relies on data
 from the States, Tribes, and other
 jurisdictions. EPA and PHS are cur-
 rently coordinating the develop-
 ment of EPA's National Environmen-
 tal Goals and revising the Healthy
 People 2000 Environmental Health
 objectives. The status of the Healthy
 People 2000 objectives is reported
 annually in the Healthy People 2000
 Review, environmental objectives are
 monitored using data from the;
 Centers for Disease Control and
 Prevention, EPA, and other sources.

State  and Tribal
Recommendations
   In their 1994 Section 305(b)
reports, 40 States, Territories, and
Tribes made recommendations for
improving water quality manage-
ment programs in order to achieve
the goals of the CWA. The recom-
mendations encompass a range of
actions at the Congressional, Fed-
eral, State, Tribal, Territorial, and
local levels and are often expressed
in terms of State, Tribal, and Territo-
rial objectives or continuing needs.
It should be emphasized that the
States, Tribes, and Territories
reported the following recommen-
dations and that this discussion does
not attempt to assess the merits of
their recommendations. Nor should
this discussion be construed as an
EPA or Administration endorsement
of any State, Tribal, or Territorial
recommendation. Many of the
recommendations do, however,
coincide with current EPA program
concerns and priorities.
   The most frequently reported
recommendations address five major
concerns:

•  Nonpoint source abatement

•  Financial and technical support
from  Federal agencies

•  Interagency data sharing and
management

• Watershed initiatives

•  Ground water management.
   Other concerns less frequently
reported include toxic pollutants,
lake management, public education,
pollution prevention,  waste man-
agement for animal and poultry
operations, water quantity impacts
on water quality, and multimedia
cycling of pollutants among air,
water, and soil. The following dis-
cussion summarizes the
recommendations most frequently
reported by the States, Tribes, and
Territories. These recommendations
are often linked and interdepen-
dent. For example, many States,
Tribes, and Territories recommend
that Federal agencies provide finan-
cial and technical support to imple-
ment watershed initiatives that pro-
vide a framework for monitoring
and managing nonpoint source
pollution. The following discussion
touches on the connections be-
tween State, Tribal, and Territorial
concerns and recommendations.

   Recommendations most often

                                     NPSs responsible for impacts, and
                                     measure the effectiveness of NPS
                                     controls. Many States reported that
                                     new monitoring methods are
                                     needed  to distinguish point source
                                     impacts from NPS impacts and to
                                     identify  specific nonpoint sources
                                     responsible for water quality degra-
                                     dation. For example, Rhode Island's
                                     305(b) report states:

                                         Decision makers at this time do
                                         not have adequate instream and
                                         site-specific water quality data.
                                         NPS management plans are
                                         currently based on generic
                                         nonpoint pollution source
                                         "types" (e.g., agriculture, urban
                                         stormwater, etc.) and cannot
                                         provide adequate prioritization
                                         of BMP controls on a specific
                                         watershed or subwatershed
                                         level.

                                         Rhode  Island suggests that a
                                     small percentage of CWA Section
                                     319 NPS Federal funds be made
                                     available for wet weather NPS moni-
                                     toring. Rhode Island reports that
                                     additional funding for NPS monitor-
                                     ing is  needed to update their assess-
                                     ment of NPS impacts and determine
                                     the effectiveness of implemented
                                     BMPs.
                                         Many States link nonpoint
                                     source monitoring and abatement
                                     to adoption of a watershed man-
                                     agement approach. The States
                                     report that a watershed protection
                                     approach can be used to target
                                     waterbodies for intensive NPS moni-
                                     toring and  to integrate local, State,
                                     and Federal efforts  to control NPS
                                     impacts. The watershed approach
encourages local involvement and
enables States to maximize efficient
use of funds by coordinating point
source  controls and NPS manage-
ment. For example, New Jersey's
305(b) report states:

    A watershed approach can
    require intensive site-specific
    monitoring designed to assess
    pollution sources and loading
    and fill  data gaps . . . Detailed
    assessments of pollution
    sources, both point and non-
    point, on a local basis, would
    allow management efforts to
    institute pollution controls on a
    finely detailed level. Working
    with local governmental agen-
    cies and environmental/citizen
    groups  can provide the Depart-
    ment [of Environmental Protec-
    tion] with enormous amounts of
    information regarding local
    activities, land uses, and point
    sources that either can poten-
    tially or are known to impair
    local water quality. These same
    agencies and groups can act to
    change land uses, zoning regu-
    lations,  agricultural practices,
    etc.

    Nebraska's  305(b) report sug-
gests that States and other govern-
ing entities  can use the watershed
approach to prioritize watersheds
for more efficient allocation of funds
to implement NPS projects:

    The Nebraska Department of
    Environmental Quality should
    continue with its systematic
    assessment of watersheds
    identified as either suspected or
    unknown with regards to
    nonpoint source pollution
    impacts. These assessments

-------
                                                             Chapter Eight  State and Tribal Recommendations  159
    should document the presence
    and quantify the magnitude of
    water quality impacts and bene-
    ficial use impairment due to
    nonpoint sources. Through the
    Nebraska Nonpoint Source
    Management Program, a listing
    of priority watersheds should be
    defined and action plans devel-
    oped in order to expedite the
    funding and implementation
    process for nonpoint source
    projects.

    The States, Tribes, and Territo-
ries also recommend implementing
a watershed approach to address
other water quality issues (in addi-
tion to NPS pollution) within a
holistic strategy. Illinois' Section
305(b) report recommends that
Federal agencies grant flexibility to
the States so that they can incorpo-
rate numerous program elements
into a watershed approach:

   As States' watershed planning
   and management efforts con-
   tinue to evolve,  Federal over-
   sight of various program activi-
   ties will  need to provide States
   with flexibility needed to imple-
   ment a watershed approach.
   Resources and incentives will
   need to be provided to assist
   States in making further
   progress, particularly in regard

     Illinois' report also refers to the
 links between the availability of
 financial resources, implementation
 of a watershed approach, and
 management of NPS pollution:

     In approaching water quality
    from a watershed approach,
    there is an immediate need for
    assessment and planning related
    to correction and prevention of
    NPS pollution. This effort will
    require both  resources and time
    to be accomplished correctly.

    Although many States, Tribes,
 and Territories report that imple-
 menting a watershed approach may
 require additional financial support,
 several  States recommend adopting
 the watershed approach to maxi-
 mize efficient use of their declining
 budgets. Massachusetts' 305(b)
 report states:

                                         Better coordination and
                                         exchange of information with
                                         other agencies is needed
                                         because of the Department [of
                                         Environmental Protection]^

                                         resources. To help alleviate this
                                         problem, the Commonwealth
                                         has adopted a watershed
                                         approach. This approach
                                         ensures interagency and inter-
                                         governmental coordination,
                                         allowing limited resources to be
                                         used to their fullest.

                                         Many States and other govern-
                                     ing entities report that shrinking
                                     budgets are a widespread problem
                                     that threatens existing water quality
                                     monitoring and assessment pro-
                                     grams in addition to new initiatives.

                                     Technical  Support

                                         Most States, Tribes, and Territo-
                                     ries expressed a common concern
                                     that they will not be able to main-
                                     tain current water quality monitor-
                                     ing and assessment activities if Fed-
                                     eral funding shrinks. Rhode Island's
                                     1994 305(b) report states:

                                         Federal funding for monitoring
                                         work is rapidly decreasing on an
                                         annual basis. At the same time,
                                         States are under severe fiscal
                                         constraints in their annual bud-
                                         get projections. Present funding
                                         does not provide for a long-
                                         term commitment to continue
                                         sampling such new water qual-
                                         ity stations. There is no easy
                                         solution currently available to
                                         solve this fiscal dilemma. Citi-
                                         zens' monitoring groups will
                                         most likely become an
    important resource in the
    State's efforts to follow present
    water quality conditions over
    future years, but such efforts
    cannot replace State mandates
    to monitor trends and present
    water quality conditions.

    Wisconsin's 305(b) report
expresses the views reported by
numerous States, Tribes, and Terri-
tories:

    With the shift in attention to
    problems more diverse and
    complex, it is  essential that
    more and better uniform data
    collection and analysis
    procedures be established to
    accurately determine the condi-
    tion of the Nation's waters
    and identify trends in water
    quality degradation and track
    progress . . . One problem with
    many water quality programs is
    there is no mechanism for fund-
    ing the monitoring  needed for
    good science.

    New Mexico  recommends full
funding for all research  programs
related to water quality:

    The U.S. Congress should pro-
    vide adequate funding to EPA,
    the USGS, and other appropri-
    ate Federal agencies to support
    basic ecological, hydrolpgic,
    medical, public health, and
    other research relevant to water
    quality protection and to sup-
    port technical assistance and
    technology transfer to the:
    States.

    The States and other entities are
also concerned about funding for
water quality management

-------
                                                            Chapter Eight  State and Tribal Recommendations  161
programs in general. Many States
specifically request that Congress
maintain funding for the CWA Sec-
tion 314 Clean Lakes Program. In
most States, lake monitoring  lags
behind monitoring of rivers and
streams. Without Section 314
grants, many States could not sup-
port lake monitoring and assess-
ment activities or restoration
projects. Resources and incentives
are also needed to address: data
availability and coordination,
ground water resource issues, wet-
lands issues, fish contamination,
interagency coordination, public
education, regulatory enforcement
and compliance, biological criteria
development, pollution prevention
and source reduction, land manage-
ment practices, and developing
technologies.

    Both Tribes and States  recom-
mend that Congress change fund-
ing allocation rules in the CWA that
limit funds for Tribal water quality
management programs. The
Campo Indian Reservation's 305(b)
report recommends that Congress
revise CWA Section 518 to remove
the cap on Federal funding for
Tribal  water programs:

   Although the CWA was
    amended in 1987 to treat
    Indian Tribes as States  under
    certain  CWA sections, funding
    available to Tribes has not fol-
    lowed the designation. A con-
    cern of paramount importance
   to the success of water quality
    management programs for the
    Campo Indian Reservation, and
    all other Indian Reservations
    pursuing authority under
   sections of the CWA, is the
   adequate amount of CWA (e.g.,
    Sections 106 and 319) funding
    available for Indian Tribes.
    Under Section 518 of the CWA,
    a maximum budget for Indian
    Tribes has been set at less than
    1% of the U.S. EPA's CWA Sec-
    tion budget. Considering that
    there are 345 Reservations in
    the U.S., the allocated funding
    falls far short of treating Indian
    Tribes as States for funding
    under CWA Sections. A more
    reasonable allocation for fund-
    ing Indian Tribes under the
    CWA would be to replace the
    less than 1 % maximum with
    minimum funding amounts.

    New Mexico's 305(b) report
also recommends expanding fund-
ing for Tribal water quality
programs while maintaining State
funding:

    The funding set aside for Indian
    Tribes in the CWA puts Tribes in
    direct competition with States

                                        for the limited available Federal
                                        funding. The funding provided
                                        to Tribes is inadequate to
                                        develop or implement effective
                                        water quality programs. The
                                        U.S. Congress should provide
                                        sufficient dedicated funds to
                                        Indian Tribes so that they can
                                        develop and implement effec-
                                        tive water quality programs.
                                        These funds should be in addi-
                                        tion to, not in place of, monies
                                        allocated to the States.

                                        Many States, Territories, and the
                                     District of Columbia stressed the
                                     need for continued appropriations
                                     to maintain or expand their Revolv-
                                     ing Fund programs for wastewater
                                     treatment plant construction. The
                                     States and other governing entities
                                     are also concerned about the high
                                     cost of abating combined sewer
                                     overflows  (CSOs). Michigan states
                                     that municipalities need funds to
                                     implement State CSO control strate-
                                     gies.  Rhode Island suggests that EPA
                                     and Congress allocate special fund-
                                     ing for implementing CSO mitiga-
                                     tion measures that would be admin-
                                     istered through the  Revolving Loan
                                     programs.

                                        The States, Tribes, and Territo-
                                     ries also request that EPA continue
                                     to provide technical support and
                                     guidance  on issues of national con-
                                     cern. Specifically, their recommen-
                                     dations include the following:

                                     • Develop technical guidance for
                                     evaluating sources of runoff pollu-
                                     tion

                                     • Provide additional guidance for
                                     assessing waterbodies with biologi-
                                     cal and chemical data and establish-
                                     ing biological standards
•  Provide guidance on stormwater
and CSO permitting

•  Finalize sediment contamination
criteria

•  Improve consistency in the imple-
mentation of whole effluent toxicity
limits in the National Pollutant Dis-
charge Elimination System (NF'DES)
program

•  Continue to sponsor professional
training courses for the States and
other governing entities on this
subjects of permit writing, compli-
ance inspections and sampling, and
enforcement

•  Provide resources and technical
support for geographic information
systems.

    In addition, the States and other
governing entities look to EPA to
improve coordination among water
quality programs.

Interagency Data
Sharing and
Management

    The need for better coordina-
tion among State, Tribal, Territorial,
and Federal water quality programs
is an underlying theme of many of
the Section 305(b)  reports. Coordi-
nation is needed among agencies as
well as across programs in all areas
of water quality concerns. Better
coordination can eliminate duplica-
tive monitoring activities (thereby
stretching limited funds) and ensure
that generated data are of adequate
quality to be shared among
programs. Improved coordination
and data sharing are also essential
elements of a watershed approach.

                                                             Chapter Eight State and Tribal Recommendations  163
    Twenty-one States, Tribes, and
Territories expressed concern that
data sharing is restricted by the lack
of common protocols for data col-
lection, analysis, and storage.
Arizona's 305(b) report states:

    Water quality information is
    collected  and disseminated by
    numerous Federal,  State, and
    local governments throughout
    Arizona. The ability of different
    agencies to use this vast data-
    base is hampered by many
    issues, including data collection
    approaches, comparable meth-
    ods, translation of databases,
    and policies on data and infor-
    mation sharing.

    Several States reference the
work of the Intergovernmental Task
Force on Monitoring (ITFM) as a
positive approach for addressing
data comparability and sharing
issues. In addition to ITFM participa-
tion, the States and other entities
suggest that EPA work with them to
develop national monitoring and
assessment strategies. Wisconsin
suggests that

•  U.S. EPA should develop a
national monitoring strategy for the
assessment of the Nation's waters,
including provisions for making
funding of monitoring part of each
program and accommodating State
priorities for data collection and
waterbody evaluation.

•  U.S. EPA's  monitoring programs
should support ecosystem manage-
ment by using certain flora and
fauna from the ecosystem being
evaluated as "ecosystem indicators"
to set a standard for when a water-
body is in good health.
    Data sharing is of special inter-
est to Tribes because Tribal water
quality is usually dependent upon
water quality and watershed activi-
ties outside the jurisdiction of the
Tribe. The Tribes need data from
outside of their jurisdictions to iden-
tify sources of water quality degra-
dation and to negotiate solutions
with non-Tribal parties. The Soboba
Band of Mission  Indians' 305(b)
report states:

    Negotiations are presently
    beginning with major off-Reser-
    vation water users,  with the aim
    of fairly and finally  apportioning
    the waters of the basin. Non-
    degradation of water quality will
    be the basic element of the
    Band's position in these nego-
    tiations. As part of these nego-
    tiations, sharing and cooperative
    analysis of data on  the hydrol-
    ogy and water quality of the
    San Jacinto watershed will be
    necessary. It is the  Band's hope
    and intent that this affirmative
    approach to water  management
    should lead to a  systematic,
    integrated water quality moni-
    toring program for the basin
    that will be of lasting benefit to
    all water users.

Ground Water
Concerns

    Many of the States and other
governing entities recommend that
EPA develop a comprehensive
framework for coordinating pro-
grams and eliminating  inconsisten-
cies among Federal programs that
address ground water.  However, the
States also suggest that they should
continue to play the primary role in

-------
164  Chapter Eight  State and Tribal Recommendations
                                     managing and implementing
                                     ground water protection programs.
                                     For example, New Mexico's 305(b)
                                     report states:

                                         Existing Federal statutes includ-
                                         ing the CWA, the Safe Drinking
                                        Water Act, the Resource Conser-
                                        vation and Recovery Act, the
                                         Insecticide, Fungicide and
                                         Rodenticide Act, and the
                                         Comprehensive Environmental
                                         Response, Compensation, and
                                         Liability Act of 1980 (Super-

                                        and procedures to control
                                        ground water quality . . . These
                                         programs have not addressed
                                        ground water in a coordinated
                                         manner and have created
                                        administrative and statutory
                                         inconsistencies which may be
                                        obstacles to effective ground
                                        water quality management.
                                         Inconsistencies between Federal
                                         laws relating to ground water
                                        quality should be removed . . .
                                        The U.S. Congress should adopt

                                        water in the State.

                                        Other States concur that EPA
                                     should coordinate ground water
                                     management and provide technical
                                     support to States and other jurisdic-
                                     tions implementing specific ground
water protection and restoration
measures at the local level. Wiscon-
sin's 305(b) report states:

    U.S. EPA should develop a coor-
    dinated ground water manage-
    ment strategy in conjunction
    with other appropriate Federal
    agencies that includes a
    drought strategy and allocation
    scheme. U.S. EPA should serve
    as a resource agency that pro-
    vides technical assistance for
    ground water quality issues as
    opposed to mandating a pro-
    cess and administrative over-
    sight. U.S. EPA needs to provide
    guidance and regional consis-
    tency on the use of nitrogen
    fertilizers due to increasing con-
    centrations of harmful nitrate-
    nitrogen in ground water
    nationwide.
     Michigan's 305(b) report
states:
    The State is restricted in some
    areas of ground water program
    development by a lack of action
    at the Federal level. To avoid
    preemption problems, the State
    relies on the Federal govern-
    ment to set certain standards
    that are later incorporated into
    State programs. The State is
    also relying on the Federal gov-
    ernment for basic scientific data
    relating to the  health impacts of
    the synergistic  effects of the
    chemical combinations most
    often found in  contaminated
    water supplies.

    A number of States, Tribes, and
Territories expressed concerns about
the continued ability to fund State
and Federal ground water research
and protection programs. Tribes
express numerous concerns about
ground water quality because many
Tribal lands lack reliable surface
water supplies due to upstream
withdrawals, arid climates, or a lack
of surface waters within Tribal
boundaries. Even Tribes in non-arid
climates rely on ground water to
supply large portions of their
domestic water supply. The Tribes
recommend that ground water
monitoring be enhanced on Tribal
lands and development of wellhead
protection programs move forward.

Conclusions

    In general, the States, Tribes,
and Territories recommend  that EPA
continue to provide general guid-
ance for establishing minimum pro-
gram elements while allowing the
States flexibility for developing and
implementing specific programs
tailored to their individual condi-
tions and needs. The States and
other governing entities also recom-
mend that Congress continue to
fund the development and distribu-
tion of technical support by EPA
and other Federal agencies, includ-
ing the USGS. Many States, Tribes,
and Territories reported that fund-
ing for water quality monitoring
should be maintained, if not
increased, because monitoring plays
a critical role  in defining water
quality issues and  measuring the
effectiveness of water quality
management programs.
    The States and other entities
also recommend that EPA continue
to advocate the watershed
approach for integrating monitoring
activities, data  sharing, ground and
surface water management, wet-
lands management, interagency
activities, and point and nonpoint
source management. However, the
States and other entities suggest
that they should maintain control
over the development and imple-
mentation of the watershed
approach within their jurisdictions.

Individual State and Territorial
Summaries
   This section provides individual
summaries of the water quality
survey data reported by the States
and Territories in their 1994 Section
305(b) reports. The summaries
provide a general overview of water
quality conditions and the most
frequently identified water quality
problems in each State and Terri-
tory. However, the use support data
contained in these summaries are
not comparable because the States
and Territories do not use compa-
rable criteria and monitoring strate-
gies to measure their water quality.
States and Territories with strict
criteria for defining healthy waters
are more likely to report that a high
percentage of their waters are in
poor condition. Similarly, States
with progressive monitoring pro-
grams are more likely to identify
water quality problems and to re-
port that a high percentage of their
waters do not fully support desig-
nated uses. As a result, one cannot
assume that water quality is worse
in those States and Territories that
report a high percentage of im-
pacted waters in the following
summaries.

Surface Water Quality

    Since enactment of the Clean
Water Act of 1972, water quality
has substantially improved near
industrial and municipal facilities.
However, pollution still prevents
about 29% of the surveyed stream
miles, 15% of the surveyed lake
acres, and 20% of the surveyed
estuaries from fully supporting
aquatic life use. Oxygen-depleting
wastes and nutrients are the most
common pollutants impacting rivers
and coastal waters. The leading
sources of river pollution include
agriculture, municipal wastewater
treatment plants, and resource;
extraction. In coastal waters, the
leading sources of pollution are
urban runoff and storm sewers,
municipal sewage treatment plants,
and combined sewer overflows.
   Toxic priority organic chemicals
impact the most lake acres, usually
in the form of a fish consumption
advisory.  These pollutants ma)'
accumulate in fish tissue at a
concentration that greatly exceeds
the concentration in the surround-
ing water. Unknown sources and
industrial dischargers are responsible
for the greatest acreage of impaired
lake waters.
   Special State concerns include
impacts from the poultry broiler
industry,  forestry activities, animal
waste runoff, and hydroelectric
generating facilities.

Ground Water Quality

   The Geological Survey of
Alabama  monitoring well network
indicates  relatively good ground
water quality. However, the number
of ground water contamination
incidents  has increased significantly
in the past few years due to  better
reporting under the Underground
Storage Tank Program and
increased public awareness of
ground water issues. Alabama has
established pesticide monitoring
and a Wellhead  Protection Program
to identify nonpoint sources of
ground water contamination and
further protect public water
supplies.

Programs to Restore
Water Quality

    In 1992, the Alabama Depart-
ment of Environmental Manage-
ment (ADEM) initiated the Flint
Creek watershed project to
simultaneously manage the many
sources degrading Flint Creek,
including intensive livestock and
poultry operations, crop production,
municipal dischargers, household
septic systems, widespread littering,
and urban runoff. Numerous Fed-
eral, State, and local agencies play a
role in the watershed project, which
includes data collection activities,
public education and outreach, and
development of a total maximum
daily load (TMDL) model for the
watershed. The model output will
show the mix of point and
nonpoint loadings that can be
permitted without violating instream
water quality standards. ADEM
expects to increase use of the
watershed protection approach.

Programs to Assess
Water Quality

    Alabama's surface water moni-
toring program includes a fixed
station ambient network, reservoir
sampling, fish tissue sampling,
intensive wasteload allocation
surveys, water quality demonstration
surveys, and compliance monitoring
of point source discharges. As a first
step in establishing biological crite-
ria, ADEM is assessing the habitats
and corresponding resident biota at
several candidate reference streams.

Surface Water Quality

    Good water quality fully
supports swimming uses in 59% of
Arizona's surveyed river miles and
94% of their surveyed lake acres.
However, Arizona reported that 51 %
of their surveyed stream miles and
28% of their surveyed lake acres do
not fully support aquatic life uses.
Arizona reported that metals, turbid-
ity, salinity, and suspended solids
were the stressors most frequently
identified in streams. The leading
stressors in lakes were salinity,
metals, inorganics, and low dissolved
oxygen. Natural sources, agriculture,
and hydrologic modification (stream
 bank destabilization, channelization,
 dam construction, flow regulation,
 and removal of shoreline vegeta-
 tion) were the most common
 sources of stressors in both streams
 and lakes, followed by resource
 extraction (mining) in streams and
 urban runoff in lakes. Nonpoirit
 sources played a role in degrading
 96% of the impaired river miles and
 93% of the impaired lake acres.

 Ground Water Quality

    Arizona is gradually establishing
 a network of water quality index
 wells in principal aquifers to
 measure ground water quality
 conditions and document future
 trends. Existing data indicate that
 ground water generally supports
 drinking water uses, but nitrates,
 petroleum products, volatile organic
 chemicals, heavy metals, pesticides,
 radioactive elements, and bacteria
 cause localized contamination in
 Arizona.  Both natural sources and
 human sources (including agricul-
 ture, leaking underground storage
 tanks, and septic tanks) generate
 these contaminants.
    The State has established 50
 ground water basin boundaries, four
 of which are designated Active
 Management Areas because they
 encompass the largest population
 centers with the greatest ground
 water demands. A Comprehensive
 State Groundwater Protection
 Program  has been initiated as a
 demonstration project in Tucson.
 Under this program, the State will
work with all interested parties to
set priorities for ground water
 management and mitigate existing
water quality problems.

    Arizona's nonpoint source con-
trol program integrates regulatory
controls with nonregulatory educa-
tion and demonstration projects.
Regulatory programs include the
Aquifer Protection Permit Program,
the Pesticide Contamination
Program, and best management
requirements for controlling nitro-
gen at concentrated animal feeding
operations. The State is also devel-
oping best management practices
for timber activities, grazing activi-
ties, urban runoff, and sand and
gravel operations. Arizona's point
source control program encom-
passes planning, facility construction
loans, permits, pretreatment,
inspections, permit compliance,
and enforcement.

Water Quality

    Recently, Federal and State
agencies increased efforts to coordi-
nate monitoring, provide more
consistent monitoring protocols,
and provide mechanisms to share
data, spurred by tightened budgets.
Monitoring  programs in Arizona
include a fixed station network,
complaint investigations and special
studies, priority pollutant monitor-
ing, and monitoring to support
biocriteria development. ADEQ will
develop narrative biological criteria
with biological, physical, and chemi-
cal data collected at over 100

Surface Water Quality

    The Arkansas Department of
Pollution Control and Ecology
(DPCE) reported that 56% of their
surveyed rivers and streams and
100% of their surveyed lake acres
have good water quality that fully
supports aquatic life uses. Good
water quality also fully supports
swimming use  in 81 % of the
surveyed river miles and 100% of
the surveyed lake acres. Siltation and
turbidity are the most frequently
 identified pollutants impairing
 Arkansas' rivers and streams, fol-
 lowed by bacteria and nutrients.
 Agriculture is the leading source of
 pollution in the State's rivers and
 streams and has been identified as a
 source of pollution in four lakeis.
 Municipal wastewater treatment
 plants, mining, and forestry also
 impact rivers and streams. Arkansas
 has limited data on the extent of
 pollution in lakes.
    Special State concerns include
 the protection of natural wetlands
 by mechanisms other than  dis-
 charge permits and the develop-
 ment of more effective methods to
 identify nonpoint source impacts.
 Arkansas is also concerned about
 impacts from the expansion of con-
 fined  animal production operations
 and major sources of turbidity and
 silt including road  construction,
 road maintenance, riparian  land
 clearing, streambed gravel removal,
 and urban construction.

 Ground Water Quality

    Nitrate contamination was
 detected in some domestic wells
 sampled in portions of the State
 undergoing rapid expansion of
 poultry and livestock operations,
 including northwest Arkansas, the
Arkansas River Valley, and southwest
Arkansas. In northwest Arkansas,
 nitrate contamination was docu-
 mented in 5% to 7% of the domes-
tic wells sampled. Wells sampled in
 pristine areas of northwest Arkansas
were not contaminated.

Programs to Restore
Water Quality

    Arkansas  has focused nonpoint
source management efforts on con-
trolling waste from confined animal
production operations. Arkansas
utilizes education, technical
assistance, financial assistance, and
voluntary and regulatory activities to
control nonpoint source pollution
from poultry, swine, and dairy
operations. Liquid waste systems are
regulated by permit and dry waste
systems are controlled by voluntary
implementation of BMPs in targeted
watersheds. Water quality is moni-
tored during watershed  projects to
evaluate the  effectiveness of the
BMPs.

Programs to Assess
Water Quality

    Arkansas classifies its water
resources by ecoregion with similar
physical, chemical, and  biological
characteristics.  There are seven
ecoregions including the Delta, Gulf
Coastal, Ouchita Mountain, Arkan-
sas River Valley, Boston  Mountain,
and Ozark Mountain  Regions. By
classifying water resources in this
manner, Arkansas can identify the
most common land uses within
each region  and address the issues
that threaten the water quality.
    The State has  increased surface
water and ground water monitoring
 to determine the fate of animal
 waste applied to pastures. Arkansas
 also conducted 10 water quality
 surveys in watersheds throughout
 the State to  determine point and
 nonpoint sources of pollution
 impacting water quality.

miles in California. The leading
sources of degradation in
California's rivers and streams are
agriculture, unspecified nonpoint
sources, forestry activities, urban
 runoff and storm sewers, and re-
 source extraction. In lakes, siltation,
 metals, and nutrients are the most
 common pollutants. Construction
 and land development pose the
 greatest threat to lake water quality,
 followed by urban runoff and storm
 sewers, forestry,  and land disposal
 of wastes.
    Metals, pesticides, trace ele-
 ments, and unknown toxic contami-
 nants are the most frequently identi-
 fied pollutants in estuaries, harbors,
 and bays. Urban runoff and storm
 sewers are  the leading source of
 pollution in California's coastal
 waters, followed by municipal sew-
 age treatment plants, agriculture,
 hydrologic  and habitat modifica-
 tions, resource extraction, and
 industrial dischargers. Oceans and
 open bays  are degraded by urban
 runoff and  storm sewers, agricul-
 ture, and atmospheric deposition.

 Ground Water Qualify

    California assigns beneficial uses
to its ground water. Salinity, total
dissolved solids, and chlorides are
the most frequently identified pol-

Surface Water Quality

    Colorado reports that 89% of its
surveyed river miles and 91 % of its
surveyed lake acres have good water
quality that fully supports designated
uses. Metals are the most frequently
identified pollutant in rivers and
lakes. High nutrient concentrations
also degrade many lake acres. Agri-
culture and mining are the leading
sources of pollution in rivers.
Agriculture, construction, urban
runoff, and municipal sewage treat-
ment plants are the leading sources
of pollution in lakes.

Ground Water Quality

    Ground water quality in Colo-
rado ranges from excellent in
mountain areas where snow fall is
heavy, to poor in alluvial aquifers of
major rivers. Naturally occurring
soluble minerals along with human
activities  are responsible for signifi-
cant degradation of some aquifers.
Nitrates and salts from agricultural
activities  have contaminated many
of Colorado's shallow aquifers, In
mining areas, acidic water and
metals contaminate aquifers. Colo-
rado protects  ground water quality
with statewide numeric criteria for
organic chemicals, a narrative stan-
dard to maintain ambient condi-
tions or Maximum Contaminant

another project, Colorado devel-
oped  agreements with the U.S.

Programs to Assess
Water Quality

    During the 1994 305(b) report-
ing cycle, Colorado switched over
from  a statewide monitoring pro-
gram to a basinwide monitoring
strategy. The basinwide  monitoring
strategy allows that State to inten-
sify monitoring in one basin per
year,  rather than perform infrequent
sampling statewide. Colorado
retained some of the old fixed-
station sampling sites to monitor
statewide trends in water quality
conditions.

Surface Water Quality

    Connecticut has restored over
300 miles of large rivers since enact-
ment of Connecticut's State Clean
Water Act in 1967. Back in 1967,
about 663 river miles (or 74% of
the State's 893 miles of large rivers
and streams) were unfit for fishing
and swimming. In 1994, Connecti-
cut reported that 222 river miles
(25%) do not fully support aquatic
life uses and 248 miles (28%) do
not support swimming due to
bacteria, PCBs, metals, oxygen-
demanding wastes, ammonia,
 nutrients, and habitat alteration.
 Sources of these pollutants include
 urban runoff and storm sewers,
 industrial dischargers, municipal
 sewage treatment plants, and in-
 place contaminants. Threats to
 Connecticut's reservoir and lake
 quality include failing septic systems,
 erosion  and  sedimentation from
 construction and agriculture, agri-
 cultural  wastes, fertilizers, and
 stormwater runoff.
    Hypoxia (low dissolved oxygen)
 is the most widespread probk'm in
 Connecticut's estuarine waten; in
 Long Island Sound. Bacteria also
 prevent shellfish harvesting and an
 advisory restricts consumption of
 bluefish and  striped bass contami-
 nated with PCBs. Connecticut's
 estuarine waters are impacted by
 municipal sewage treatment plants,
 combined sewer overflows, indus-
 trial discharges and runoff, failing
 septic systems, urban runoff, cind
 atmospheric  deposition. Historic
 waste disposal practices also con-
 taminated sediments in Connecti-
 cut's harbors and bays.

 Ground Water Quality

    The State and USGS have iden-
 tified about 1,600 contaminated
 public and private wells since the
 Connecticut  Department of Environ-
 mental Protection (DEP) began
 keeping  records in 1980. Connecti-
 cut's Wellhead Protection Program
 incorporates  water supply planning,
 discharge permitting, water diver-
sion, site remediation, prohibited
activities, and numerous nonpoint
source controls.

Programs to Restore
Water Quality

    Ensuring that all citizens can
share in the benefits of clean water
will require continued  permit
enforcement, additional advanced
wastewater treatment, combined
sewer separation, continued aquatic
toxicity control, and resolution of
nonpoint source issues. To date,
14 sewage treatment facilities have
installed advanced treatment to
remove nutrients. Nonpoint source
management includes education
projects and a permitting program
for land application of sewage, agri-
cultural sources,  and solid waste
management facilities.
    Wetlands are protected by the
State's Clean Water Act and Stan-
dards of Water Quality. Each
municipality has an Inland Wetlands
Agency that regulates filling and
establishes regulated buffer areas
with DEP training and oversight.
Connecticut's courts have strongly
upheld enforcement of the wetlands
acts and supported regulation of
buffer  areas to protect wetlands.

Programs to Assess
Water Quality

    Connecticut samples physical
and chemical parameters at 27 fixed
stream sites and biological param-
eters at 47 stream sites. Other
activities include intensive biological
surveys, toxicity testing, and fish
and shellfish tissue sampling for
accumulation of toxic chemicals.

Surface Water Quality

    Delaware's rivers and streams
generally meet standards for aquatic
life uses, but 93% of the surveyed
stream miles and 76% of the sur-
veyed lake acres do not  meet bacte-
ria criteria for swimming. Bacteria
are the most widespread contami-
nant in Delaware's surface waters,
but nutrients and toxics  pose the
most serious threats to aquatic life
and human health. Excessive nutri-
ents stimulate algal blooms and
growth of aquatic weeds. Toxics
result in six fish consumption restric-
tions in three basins, including  Red
Clay Creek, Red Lion Creek, the St.
Jones  River, and the Delaware Estu-
ary. Agricultural runoff, septic sys-
tems,  urban runoff, municipal sew-
age treatment plants, and  industrial
dischargers are the primary sources
of nutrients and toxics in Delaware's
surface waters.

Ground Water Quality

    High-quality ground wate:r
provides two-thirds of Delaware's
domestic water supply. However,
nitrates, synthetic organic chemicals,
saltwater, and iron contamincite
isolated wells in some areas. In  the
agricultural areas of Kent and Sussex
counties, nitrates in ground water
are a potential health concern and
a potential source of nutrient
contamination in surface waters.
Synthetic organic chemicals have
entered some ground waters from
leaking industrial underground
storage tanks, landfills, abandoned
hazardous waste sites, chemical
spills and leaks, septic system;;,  and
agricultural activities.

approach to determine the most
effective and efficient methods for
protecting water quality or abating
existing problems. Under the water-
shed approach, DNREC will evaluate
all sources of pollution  that may
impact a waterway and target the
most significant sources for manage-
ment. The Appoquinimink River
subbasin, the Nanticoke River
subbasin, the Delaware's Inland Bays
subbasin, and the Christina River
subbasin are priority watersheds
targeted for development of inte-
grated pollution control strategies.
    Delaware's Wellhead Protection
Program establishes cooperative
arrangements with local govern-
ments to manage sources of ground
water contamination. The State may
assist local governments in  enacting
zoning ordinances, site plan reviews,
operating standards, source prohibi-
tions, public education, and ground
water monitoring.

Surface Water Quality

    Poor water quality still character-
izes the District's surface waters, but
water quality has stabilized and is
improving in some areas. The recov-
ery of submerged aquatic vegetation
and fish  communities in the Anacos-
tia and Potomac Rivers  provides
qualitative evidence that water qual-
ity is improving. However, a fish
consumption advisory and a
swimming ban remain in effect for
all District surface waters, and sedi-
ment contamination degrades
aquatic life on the Anacostia River.
Combined sewer overflows are the
main source of bacterial  pollution
that causes unsafe swimming condi-
tions. Urban runoff may  be the
source of high concentrations of
cadmium, mercury, lead, PCB:>,
PAHs, and DDT found in sediment
samples.

Ground Water Quality

    During the 1994 305(b) assess-
ment period, the District initiated
ground water monitoring. The first
round of sampling revealed that the
ground water is potable. Some
pollutants were detected at low
concentrations in isolated cases.
Ground water is not a public drink-
ing water source in the District, but
the District has a comprehensive
State ground water protection
program to assess and manage the
resource. The program includes an
ambient ground water sampling
network, ground water quality regu-
lations (including numerical arid
narrative criteria), and guidelines for
preventing and remediating ground
water quality degradation.

trols for urban areas and promoting
the watershed protection approach
to clean up waterbodies that cross
political boundaries, such as the
Anacostia River. The District needs
Maryland's cooperation to control
pollution entering upstream tributar-

funds will be needed to implement
urban stormwater retrofits, CSO
controls, and revegetation projects
in both the District and Maryland
to improve water quality in the

plankton at 3 stations. The District
samples metals in the water column
four times a year and analyzes toxic
pollutants in fish tissue once a year.

Surface Water Quality

    Overall, the majority of Florida's
surface waters are of good quality,
but problems exist around densely
populated urban areas, primarily in
central and southern Florida. In
rivers, nutrient enrichment, low
dissolved oxygen, high bacteria
counts, turbidity, and suspended
solids degrade water quality. In
lakes, the leading problems include
algal blooms, turbidity, and nutrient
enrichment.  In estuaries,  algal
blooms, nutrient enrichment, low
dissolved oxygen, and turbidity
degrade quality.  Urban stormwater,
agricultural runoff, domestic waste-
water, industrial wastewater, and
hydrologic modifications are the
major sources of water pollution in
Florida.
    Special State concerns include
massive fish kills (as much as 20
tons of fish) in the Pensacola Bay
system, widespread toxic contami-
nation in sediments, widespread
mercury contamination  in fish,
bacterial contamination  in the
Miami River, and algal blooms and
extensive die-off of mangroves and
seagrasses in Florida  Bay.

Ground Water Quality

    Data from 1,919 wells in
Florida's ambient monitoring
network indicate generally good
water quality, but local ground
water contamination problems exist.
Agricultural chemicals, including
aldicarb, alachlor, bromacil,
simazine, and ethylene dibromide
(EDB) have caused local and
regional (in the case of EDB) prob-
lems. Other threats include petro-
leum products from  leaking under-
ground storage tanks, nitrates from
dairy and other livestock operations,
fertilizers  and pesticides  in storm-
water runoff, and toxic chemicals in
leachate from hazardous waste sites.
The State requires periodic testing
of all community water  systems for
118 toxic organic chemicals.

about 4,600 ground water and
surface water discharge facilities.
The State also encourages reuse of
treated wastewater (primarily for
irrigation) and discharge into
constructed wetlands as an alterna-
tive to direct discharge into natural
surface waters and ground water.
    Florida's Stormwater Rule and
implementing regulations are the
core of the State's nonpoint source
program. These regulations require
all new developments to retain the
first inch of runoff water in ponds
to settle  out sediment and other
pollutants. Ongoing contracts focus
on best management practices for
other nonpoint sources, including
agriculture, septic tanks, landfills,
mining, and hydrologic modifica-
tion.

Programs to Assess
Water Quality

    Florida's Surface Water Assess-
ment Program (SWAMP) will iden-

develop  community bioassessment
protocols; develop and implement a

quality trends and determine
current conditions; and perform
special water quality assessments if
funds are available. The State

Surface Water Quality

    Improvements in wastewater
treatment by industries and munici-
palities have made it possible for
Georgians to fish and swim in areas
where water quality conditions were
unacceptable for decades. Water
quality in Georgia streams, lakes,
and estuaries during 1992 and 1993
was good, but the number of
stream miles and lake acres not fully
supporting designated uses
increased. The number of fish advi-
sories also grew from four to nine
during 1992-1994. However, this is
a result of more stringent stream
standards, increased sampling, and
access to additional data. Persistent
problems include mud, litter, bacte-
ria, pesticides, fertilizers, metals,  oils,
suds, and other pollutants washed
into rivers and lakes by stormwater.

Ground  Water Quality

    Georgia's ambient Ground
Water Monitoring Network consists
of 150 wells sampled periodically.
To date, increasing nitrate concen-
trations in the Coastal Plain are the
only adverse trend detected by the
monitoring  network, but nitrate
concentrations are still well  below
harmful levels in most wells. Addi-
tional nitrate sampling in 500 wells
revealed that nitrate concentrations
exceeded EPA's Maximum Contami-
nant Level (MCL) in less than 1 % of
the tested wells. Pesticide monitor-
ing indicates that pesticides do not
threaten Georgia's drinking  water
aquifers at this time.

river basin in the State. The State
began developing comprehensive
plans for the Chattahoochee and
Flint River Basins in 1992 and the
Oconee and Coosa River Basins in
1993. Georgia is also participating
in a Tri-State Comprehensive Study

ing flow and allocating assimilative
capacity. Other interstate basin
projects include the Savannah

Surface Water Quality

    Most of Hawaii's waterbodies
have variable water quality due to
stormwater runoff. During dry
weather, most streams and estuaries
have good water quality that fully
supports beneficial uses, but the
quality declines when stormwater
runoff carries pollutants into surface
waters. The most significant pollu-
tion problems in Hawaii are siltation
and turbidity,  nutrients, fertilizers,
toxics, pathogens, and pH from
nonpoint-sources, including agricul-
ture and urban runoff. Very few
point sources discharge into
Hawaii's streams; most industrial
facilities and wastewater treatment
plants discharge into coastal waters.
Other concerns include explosive
algae growth in West Maui and
Kahului Bay, a fish consumption
advisory for lead in talipia caught in
Manoa Stream, and sediment
contamination from discontinued
wastewater discharges at Wailoa
Pond and Hilo Bay.

Ground Water Quality

    Compared to mainland States,
Hawaii has very few ground water
problems due to a long history of
land use controls for ground water
protection. Prior to 1961, the  State
designated watershed reserves to
protect the purity of rainfall recharg-
ing ground water. The Under-
ground Injection Control Program
also prohibits wastewater injection
in areas surrounded by "no-pass"
lines. However, aquifers outside of
reserves and no-pass lines may be
impacted by injection wells, house-
hold wastewater disposal systems,
such as seepage pits and cesspools,
landfills, leaking underground
storage tanks, and agricultural
return flows.

land uses. These standards include
criteria, techniques, and methods
for controlling sediment erosion
from land-disturbing activities. The
State would like to enact ordinances
that require the rating of pesticides
on their potential to migrate
through soil into ground water. The
State would regulate the use of
pesticides that pose a threat to
ground water. Until more stringent
ordinances can be enacted, the
State recommends using alternatives
to pesticides, such as natural preda-

Programs to  Assess

    Hawaii has scaled back its water
quality monitoring program because
of budgetary constraints. The State
has halted toxics monitoring, fish
tissue contamination monitoring,
and biological monitoring and elimi-
nated sampling at numerous fixed
monitoring stations. The State also
reduced the frequency of bacterial
monitoring at coastal beaches. The
State does not expect conditions to
change in the near future.

Surface Water Quality

    Idaho omitted its water quality
assessment for surface waters in
their 1994 305(b) report because
the State is in the middle of a major
overhaul of its water quality man-
agement program. Idaho is restruc-
turing its program around the
watershed protection approach.
As a first step, Idaho is redesignating
its waterbodies and expanding its
assessment database to include
smaller streams that previously were
not assessed. The State postponed
its water quality assessment until all
surface waters are designated and
classified under a consistent system.
    Idaho's Department of Environ-
mental Quality (DEQ) identified
several waterbodies with significant
problems.  Heavy metals and nutri-
ents impact the Coeur d'Alene River
drainage, while nutrients and sedi-
ment impact Henry's Fork. The
middle Snake River exhibits severe
eutrophication from nutrient enrich-
ment. Mercury contaminates fish
tissue in Brownlee Reservoir, and the
Cascade Reservoir does not support
agricultural uses due to overenrich-
ment with nutrients.

Ground Water Quality

    The Idaho Statewide Monitoring
Program for Ground Water samples
over 800 wells. This program and
other specific projects have indi-
cated that nitrates,  petroleum
products, solvents,  and pesticides
are the most prevalent pollutants in
ground water. The Idaho  Legislature
adopted the Ground Water Quality
Plan in 1992. This plan sets four
priority issues:  (1)  evaluation of
existing ground water programs,
(2) development of State  ground
water standards, (3) development
of a State wellhead protection
program, and (4) classification of
Idaho's aquifers.  Ground water qual-
ity protection programs in Idaho
include underground injection
control, ground water vulnerability
mapping,  and management for
animal waste, landfills, pesticides
application, underground  storage
tanks, and sewage  disposal.

Programs to Restore
Water Quality

    EPA has primary responsibility
for issuing NPDES permits in Idaho.
Idaho's DEQ is concerned that EPA
is not issuing permits for minor
point source dischargers, and
inspections of permitted and
unpermitted dischargers are rare.
Neither DEQ or EPA have sufficient
staff to conduct compliance inspec-
tions. Without oversight, there are
no assurances that these facilities are
being properly operated and meet
water quality standards.

Programs to Assess
Water Quality

    DEQ operates a water quality
monitoring program that measures
biological, physical, and chemical
parameters. Data collection varies in
intensity, from desktop reviews of
existing data (Basic or Level I),
through qualitative surveys and
inventories that cannot be repeated
with confidence  (Reconnaissance or
Level II), to quantitative measure-
ments that can be repeated and
yield data suitable for statistical
analysis (Intensive or Level III).

Surface Water Quality

    Overall water quality has
steadily improved over the past 24
years since enactment of the Illinois
Environmental Protection Act.
Trend analysis generally indicates
stable or improving trends in stream
concentrations of dissolved oxygen,
oxygen-depleting wastes,  and am-
monia  consistent with the contin-
ued decline in point source impacts.
However, dissolved oxygen deple-
tion and  ammonia still impair
streams, as do nutrients, siltation,
habitat/flow alterations, metals, and
suspended solids. The State is also
concerned about upward  trends in
nutrient concentrations  detected in
several basins that probably result
from nonpoint sources. Other ma-
jor sources of river pollution include
persistent point sources, hydrologic/
habitat modification, urban runoff,
and resource extraction.
    Trend analysis also indicates
improving water quality in lakes.
The most prevalent causes of re-
maining pollution in lakes include
nutrients, suspended solids, and
siltation. The most prevalent sources
of pollution in lakes include  con-
taminated sediments, agriculture,
and hydrologic/habitat alterations.
    Water quality also continues to
improve in the Illinois portion of
Lake Michigan. Trophic status im-
proved from mesotrophic/eutrophic
conditions in the 1970s to oligo-
trophic conditions today.

Ground Water Quality

    Ground water quality is gener-
ally good, but past and present
activities contaminate ground water
in isolated areas. Ground water is
contaminated around leaking under-
ground gasoline storage tanks, large
aboveground petroleum storage
facilities, agricultural chemical opera-
tions, salt piles,  landfills, and waste
treatment, storage, and disposal
facilities.

Programs to Restore
Water Quality

    The Illinois Environmental Pro-
tection Agency (IEPA),  Bureau of
Water, is committed to implement-
ing  a Targeted Watershed Approach
in which  high-risk watersheds are
identified, prioritized, and selected
for integrated and cooperative
assessment and protection. This
approach represents an expansion

and evolution of their previous
efforts in geographic targeting.
Current nonpoint source program
activities focus on improving public
awareness and adding land use data
to the nonpoint source database
available statewide.
    Illinois established a Great Lakes
Program Office in FY93 to oversee
all Lake Michigan programs on  a
multimedia basis. Activities include
promotion of pollution prevention
for all sources of toxics in all media
(such as air and water).

Programs to Assess
Water Quality

    The Division of Water Pollution
Control spent $5.5  million on a
diverse  set of monitoring programs
during 1992  and 1993.  These pro-
grams include ambient and toxicity
monitoring, pesticide monitoring,
intensive river basin surveys, fish
contaminant monitoring, and volun-
teer lake monitoring. These pro-
grams generate a rich inventory of
monitoring data for assessing water
quality conditions across the State.
IEPA based their 1994 assessments
on data from nearly 3,500 stations.

Surface Water Quality

    Over 99% of the surveyed lake
acres and 79% of the surveyed river
miles have good water quality that
fully supports aquatic life. However,
only 18% of the surveyed river miles
support swimming due to high
bacteria concentrations. A fish con-
sumption advisory impairs all of
Indiana's  Lake Michigan shoreline.
The pollutants most frequently iden-
tified in Indiana waters include
bacteria, priority organic
compounds, oxygen-depleting
wastes, pesticides, metals, cyanide,
and ammonia. The sources of these
pollutants include industrial facilities,
municipal/semipublic wastewater
systems, combined sewer overflows,
and agricultural nonpoint sources.
    Indiana identified elevated
concentrations of toxic substances
in about 8% of the river miles
monitored for toxics. High concen-
trations of PCBs,  pesticides, and
metals were most common in sedi-
ment samples and in fish tissue
samples. Less than 1% of the sur-
veyed lake acres contained elevated
concentrations of toxic substances
in their sediment.

Ground Water Qualify

    Indiana has a plentiful ground
water resource serving 60% of its
population for drinking water and
filling many of the water needs of
business,  industry, and agriculture.
Although most of Indiana's ground
water has not been shown to be
adversely impacted by human activi-
ties, the State has documented over
863 sites of ground water contami-
nation. Nitrates are the most com-
mon pollutant detected in wells,
followed by volatile organic chemi-
cals and heavy metals. In agricul-
tural regions, data indicate that
7% to 10% of the rural drinking
water wells contain unacceptable
nitrate concentrations and some
detectable quantity of pesticides.
Heavy metal contamination is asso-
ciated with waste disposal sites.

Programs to Restore
Water Quality

    Since 1972, Indiana has spent
over $1.4 billion in Federal construc-
tion grants, $207 million in State
funds,  and $190 million in match-
ing local funds to construct or
upgrade sewage treatment facilities.
As a result of these expenditures,
53% of Indiana's population is now
served  by advanced sewage treat-
ment. The State issues NPDES per-
mits to ensure that these new and
improved facilities control pollution.
Indiana is increasing enforcement
activities to ensure compliance with
permit requirements.

Programs to Assess
Water Quality

    Indiana initiated a 5-year
baseline biological sampling pro-
gram in 1989. As of 1994, the State
had collected 2,000 aquatic insect
samples at 439  sites representing
81 % of the State's geographical
area. In the future, the State will be
able to detect deviations from the
baseline dataset. Indiana and EPA
Region 5 are also developing fish
community measurements for evalu-
ating biological  integrity in Indiana's
rivers and streams.

Surface Water Quality

    Sediment and plant nutrients
from agricultural sources, modifica-
tions to stream habitat and hydrol-
ogy, and natural conditions (such as
shallowness in lakes) impair aquatic
life uses in 48% of the surveyed
rivers, 35% of the surveyed lakes,
and 33% of the surveyed flood
control reservoirs.  Swimming use is
impaired in 92% of the 556 sur-
veyed river miles and 27% of the
surveyed lakes, ponds, and  reser-
voirs. Saylorville, Coralville, and
Rathburn Reservoirs have good
water quality that  fully supports all
designated uses, but siltation
severely impacts Red Rock Reservoir.
Point sources still pollute about 5%
of the surveyed stream miles and
one lake.

Ground Water Quality

    Ground water supplies about
80% of all Iowa's drinking water.
Agricultural chemicals, underground
storage tanks, agricultural drainage
wells,  livestock wastes, and
improper management of hazardous
substances all contribute to some
degree to ground water contamina-
tion in Iowa. Nitrate concentrations
exceed the EPA's Maximum Con-
taminant Level in 10 of the State's
1,140 public ground water supplies.
Several studies have detected low
levels  of common agricultural pesti-
cides and synthetic organic com-
pounds, such as solvents and
degreasers, in both untreated and
treated ground water. In most
cases, the contaminants appear in
small concentrations thought to
pose no immediate threat to public
health, but little is known about the
health effects of long-term exposure
to low concentrations of these
chemicals.

Programs to Restore
Water Quality

    In 1979, Iowa began imple-
menting its agricultural nonpoint
control strategy with education
projects and cost-share programs to
control sediment, the greatest
pollutant, by volume, in the State.
Later, Iowa adopted rules that
require that land disposal of animal
wastes not contaminate surface and
ground waters. Landfill rules estab-
lish specific siting, design, operation,
and monitoring criteria, and require
annual inspections and permit

renewals every 3 years. Iowa also
regulates construction in floodplains
to limit soil erosion and impacts on
aquatic life.

Programs to  Assess

    Iowa's DNR maintains a fixed
sampling network  and conducts
special intensive studies at selected
sites. The State routinely monitors
metals, ammonia,  and residual chlo-
rine at the fixed sampling sites, but
not pesticides. However, pesticides
were monitored for special studies
examining the fate of pesticides in
Iowa rivers and levels of pesticides
in water supply reservoirs. Limited
monitoring for toxics in sediment
was conducted as  part of a special
study in 1992 and 1993. Routine
sampling has not included biological
sampling in  the past, but the role of
biological sampling continues to
grow.  In 1994, Iowa initiated a pilot
study to  establish biologically based
water quality criteria for wadeable
streams in each ecoregion.

Surface Water Quality

    Suspended solids and dissolved
solids impair aquatic life uses in
93% of Kansas' surveyed streams.
Bacteria also prevent 95% of the
surveyed  streams from fully support-
ing swimming uses. Runoff from
feedlots, animal holding areas, and
pastureland introduce pathogen
bacteria into rivers and streams.
Discharges of undertreated or
untreated wastewater from sewage
treatment plants also elevate patho-
gen bacteria levels in Kansas waters.
Erosion of farmland soils and urban
runoff are the principal sources of
suspended solids. Irrigation return
flows, oil and natural gas extraction
activities, and natural sources intro-
duce dissolved solids.
    Cultural eutrophication is
responsible for 34% of poor water
quality conditions in Kansas' sur-
veyed lakes, and pesticides impair
an additional 23% of the surveyed
lakes. Overall, agricultural activities
are responsible for almost half of the
pollution in the State's lakes. Agri-
cultural activities and hydromodifi-
cation are the major sources of
impacts in wetlands.

Ground Water Quality

   The Kansas Department of
Health and Environment (DHE) has
documented ground water contami-
nation from human activities at
nearly 350 sites in the State. Under-
ground storage tanks, oil and natu-
ral gas operations, and agriculture
are the most significant sources of
ground water contamination in
Kansas. Kansas maintains a ground
water monitoring network of 242
wells. During 1990-1993, nitrate
concentrations exceeded EPA's
Maximum Contaminant Level  in
11% of 618 ground water samples.
A State Wellhead Protection Pro-
gram  is still under development,
and several Kansas communities are
developing local plans.

Programs to Restore
Water Quality

    Kansas requires permits for live-
stock operations that utilize waste-
water control facilities (such as
manure pits, ponds, or lagoons);
confine 300 or more head of cattle,
hogs, sheep, or a combination of all
three; or house a commercial
poultry flock of 1,000 or more birds.
DHE may also require permits for
other livestock operations that have
the potential to create pollution
problems, such as open lots located
adjacent to creeks or operations
with a history of improper waste-
water disposal practices. The major
elements of the Kansas Nonpoint
Source Pollution Control Program
include interagency coordination,
information and education, techni-
cal assistance, enforcement, and
water quality certification.

Programs to Assess
Water Quality

    Every year, DHE collects and
analyzes about 1,500 surface water
samples, 50 aquatic insect samples,
and 40 composite fish tissue
samples from stations located
throughout the State. Wastewater
samples are collected at about 50
municipal sewage treatment plants,
20 industrial facilities, and  3 Federal
facilities to evaluate compliance with
discharge permit requirements. DHE
also conducts special studies and
prepares about 100 site-specific
water quality summaries at the
request of private citizens or other

Surface Water Quality

    About 83% of Kentucky's
surveyed rivers (including the Ohio
River) and 95% of surveyed lake
acres have good water quality that
fully supports aquatic life. Swim-
ming use is fully supported in 100%
of the surveyed lake acres, but 52%
of the surveyed river miles do not
fully support swimming due to ele-
vated bacteria levels. Fecal coliform
bacteria, siltation, and oxygen-
depleting substances are the most
common pollutants in Kentucky
rivers. Sewage treatment facilities
are still a leading source of fecal
coliform bacteria and oxygen-
depleting substances, followed by
agricultural runoff, septic tanks, and
straight pipe discharges. Surface
mining and agriculture are the ma-
jor sources of siltation. Nutrients
from agricultural runoff and septic
tanks have the most widespread
impacts on lakes.
    Declining trends in chloride
concentrations and nutrients pro-
vide evidence of improving water
quality in Kentucky's rivers and
streams. The State also lifted a
swimming advisory on 76 miles of
the North Fork Kentucky River,
although the advisory remains in
effect on 86 miles. Fish consump-
tion advisories remain posted on
three creeks for PCBs and on  the
Ohio River for PCBs and chlordane.
The State issued new advisories for
the Green River Lake because of
PCB spills from a gas  pipeline com-
pressor station and for five ponds
on the West Kentucky Wildlife Man-
agement Area because of mercury
contamination from unknown
sources.

Ground Water  Quality

    Underground storage tanks,
septic tanks, abandoned hazardous
waste sites, agricultural activities,
and landfills are estimated to  be the
top five sources of ground water
contamination in Kentucky. Bacteria
is the major pollutant in ground
water. The State is concerned about
the lack of ground water data,
absence of ground water regula-
tions, and the potential for ground
water pollution in karst regions of
the State.

Programs to Restore
Water Quality

    Kentucky's revolving fund  pro-
gram supported 26 wastewater
treatment projects completed  in
1992-93 and another 25 ongoing
projects. These projects either
replaced outdated or inadequate
treatment facilities or provided cen-
tralized treatment for the first  time.
Kentucky requires toxicity testing of
point source discharges and permits
for stormwater outfalls and
combined sewer overflows. The
nonpoint source program oversees
projects addressing watershed
remediation, education, training,
technical assistance, and evaluation
of best management practices.

Programs to Assess
Water Quality

    Kentucky sampled 44 ambient
monitoring stations characterizing
about 1,432 stream miles during
the reporting period. The State
performed biological sampling at
24 of these stations. Seven lakes
were sampled to detect eutrophica-
tion trends and 2 lakes were
sampled to analyze the impact of
suspended solids on recreational
activities. The State also performed
five intensive studies to evaluate
point source and nonpoint source
impacts, establish baseline water
quality measurements, and reevalu-
ate water quality in several streams.

include sewage discharges from
municipal treatment plants, subdivi-
sions, trailer parks, and apartment
complexes. Septic tanks, sewage/
stormwater overflows, pastures, and
rangeland also generate  bacterial
pollution. Agricultural runoff gener-
ates oxygen-depleting substances
and nutrients.
    In  lakes, noxious aquatic plants
(which result from high nutrient

lem, followed by bacteria, low

sources, industrial point sources,
and petroleum extraction activities.
In estuaries, oil and grease, nutri-
ents, and bacteria are the most

charges, sewer/stormwater overflow,
and septic tanks are the leading
sources of pollution in estuaries.
Hydrologic modification impacts

Ground Water Quality

    The quality of water  in the
State's  major aquifer systems
remains excellent. Of special con-
cern, however, are the shallow/ aqui-
fers and the water-bearing zones
that are not used as major sources
of water. These strata contribute
significantly to the water balance of
the deeper aquifers, but the shallow
aquifers are increasingly threatened.

Programs to Restore
Water Quality

    Currently, most reductions in
nonpoint source pollution result
from cooperative demonstration
projects due to  a lack of regulatory
authority in Louisiana to control
nonpoint source pollution. These
projects have demonstrated alterna-
tive rice farming management prac-
tices to reduce sediment and nutri-
ents in the Mermentau River Basin,
advocated lawn care management
to reduce erosion and runoff in the
Bayou Vermilion watershed, and
reduced fecal coliform concentra-
tions in the Tangipahoa River by
implementing septic tank and dairy
waste lagoon education programs
and upgrading  municipal waste-
water treatment systems.

    The surface water monitoring
program consists of a fixed-station

Surface Water Quality

    Maine's water quality has sig-
nificantly improved since enactment
of the Clean Water Act in 1972.
Atlantic salmon and other fish now
return to Maine's rivers, and waters
that were once open sewers are
now clean enough to swim in.
Ninety-nine percent of the State's
river miles, 81 % of the lake acres,
and 90% of the estuarine waters
have good water quality that fully
supports aquatic life uses. Dioxin in
 fish tissue is the most significant
 problem in major rivers. Oxygen-
 depleting substances from nonpoint
 sources and bacteria from inade-
 quate sewage treatment are the
 most significant problem in smaller
 rivers and streams. Lakes are
 impacted by oxygen-depleting
 substances from nonpoint sources,
 including urban runoff, agriculture,
 and forestry activities. Bacteria from
 municipal treatment plants and
 small dischargers contaminate shell-
 fish beds in estuarine waters.

 Ground Water Quality

    The most significant ground
 water impacts include petroleum
 compounds from leaking under-
 ground and aboveground storage
 tanks, other organic chemicals from
 leaking storage facilities or disposal
 practices, and bacteria from surface
 disposal systems or other sources.
 Maine requires that all underground
 tanks be registered and that inad-
 equate tanks be removed. About
 23,000 tanks have been removed
 since 1986. Maine also regulates
 installation of underground storage
 tanks and closure of landfills to
 protect ground water resources
 from future leaks.

 Programs to  Restore
Water Quality

   Maine restored designated uses
 in 20 miles of rivers by working
with  Kraft pulp and paper mill!; to
 reduce  the levels of dioxin in their
discharges. Construction of small

wastewater treatment systems also
eliminated some bacteria problems
and dissolved oxygen problems on
small streams. However, as the State
makes progress in restoring waters
impacted by point sources, new
water quality problems emerge
from nonpoint sources. Therefore,
the most important water quality
initiatives for the future include
implementing pollution prevention,
nonpoint source management,
watershed-based planning, coordi-
nated  land use management, and
water  quality monitoring. The State
is linking pollution prevention with
the watershed protection approach
in a pilot project within the Andro-
scoggin  River basin. The  State is
providing local officials and citizen
groups with technical assistance to
identify problem areas and develop
local solutions for reducing pollution
generation throughout the water-
shed.

 Programs to Assess
Water Quality

    Maine's surface water monitor-
 ing program includes ambient water
 quality monitoring, assimilative
 capacity and wasteload allocation
 studies,  diagnostic studies, treat-
 ment plant compliance monitoring,
 and special investigations. Due to
 budgetary constraints, some of
 these activities are much more
 limited in scope than is desirable for
 accurately characterizing water
 quality conditions in Maine.

Surface Water Quality

    Overall, Maryland's surface
waters have good quality, but excess
nutrients, suspended sediments,
bacteria, toxic materials, or stream
acidity impact some waters. The
most serious water quality problem
in Maryland is the continuing accu-
mulation of nutrients in estuaries
and lakes from agricultural runoff,
urban runoff,  natural nonpoint
source runoff, and point source dis-
charges. Excess nutrients stimulate
algal blooms and low dissolved oxy-
gen levels that adversely impact
water supplies and aquatic life.
     Sources of sediment include
 agricultural runoff, urban runoff,
 construction activities, natural ero-
 sion, dredging, forestry, and mining
 operations. In western Maryland,
 abandoned coal mines release acidic
 waters that severely impact some
 streams. Agricultural runoff, urban
 runoff, natural runoff, and failing
 septic systems elevate bacteria con-
 centrations and cause continuous
 shellfish harvesting restrictions in
 about 104 square miles of estuarine
 waters and cause temporary restric-
 tions in another 72.3 square miles
 after major rainstorms.

 Ground Water Quality

     Maryland's ground water
 resource is of generally good
 quality.  Localized problems include
 excess nutrients (nitrates) from fertil-
 izers and septic systems; bacteria
 from septic systems and surface
 contamination; saline water  intru-
 sion aggravated by ground water
 withdrawals in the coastal plain;
 toxic compounds from septic tainks,
 landfills, and spills; petroleum prod-
 ucts from leaking storage facilities;
 and acidic conditions and metals
 from abandoned coal mine drainage
 in western  Maryland. Control efforts
 are limited to implementing agricul-
 tural best management practices
 and enforcing regulations for septic
 tanks, underground storage tanks,
 land disposal practices, and well
 construction.

    each individual nonpoint source
category. Urban runoff is addressed
through stormwater and sediment
control laws that require develop-
ment projects to maintain predevel-
opment runoff patterns through
implementation of best manage-
ment practices (BMPs), such as
detention ponds or vegetated
swales. The Agricultural Water Qual-
ity Management Program supports
many approaches, including Soil
Conservation and Water Quality
Plans, implementation of BMPs, and
education. The Agricultural Cost
Share Program has provided State,
and some Federal, funds to help
offset the costs of implementing
almost 8,000 agricultural BMPs
since 1983. An Animal Waste Permit
Program requires discharge permits
for facilities that will have a defin-
able discharge to waters of the
State.

Programs to Assess
Water Quality

    Maryland's monitoring program
includes a fixed-station network,
compliance sampling at  point
source discharges, bioassay tests of
effluent toxicity, special intensive
sampling programs on the Potomac

monitoring,  fish tissue and shellstock
sampling, bacterial sampling in
shellfish waters, phytoplankton
sampling, biological monitoring,
and habitat assessments.

Surface Water Quality

    The 1994 report does not reflect
the progress made in cleaning  up
Massachusetts' rivers and lakes
because reporting total miles free of
all contaminants obscures progress
in removing some contaminants
from many waters. The method of
reporting survey results obscures the
statewide reduction in oxygen-
depleting wastes  because bacteria,
nutrients, toxic pollutants, ammonia,
and acidity still impact about half of
the surveyed river miles, lake acres,
and estuarine waters in the State.
The leading sources of contamina-
tion in Massachusetts' surface waters
are stormwater runoff, combined
sewer overflows, and municipal
sewage treatment plants.
    Quabbin Reservoir's 25,000
acres support swimming and
aquatic life, but high levels of
mercury in sport fish restrict fish
consumption. Unlike other wciter-
body types, coastal water bacterial
quality has deteriorated  over the
past 10 years, especially in areas
such as Cape Cod where nonpoint
source pollution has resulted in a
tenfold increase in shellfish bed
closures.

Ground Water Quality

    Contaminants have  been
detected in at least 206 ground
water suppy wells in 87 municipali-
ties. Organic chemicals (especially
TCE) contaminate 60% of these
wells.  Other contaminants include
metals, chlorides, bacteria, inorganic
chemicals, radiation, nutrients, tur-
bidity, and pesticides. Since 1983,
Massachusetts has required permits
for all industrial discharges into
ground waters and sanitary waste-
water discharges of 15,000 gallons
or more per day.  The permits
require varying degrees  of waste-
water treatment based on the qual-
ity and use of the receiving ground
water. Additional  controls are
needed to eliminate contamination
from septic systems and sludge
disposal.

Programs to Restore
Water Quality

    Wastewater treatment plant
construction has resulted in signifi-
cant improvements in water quality,
but $7 billion of unfunded waste-
water needs remain. The Nonpoint
Source Control Program has imple-
mented 35 projects to provide tech-
nical assistance, implement best
management practices, and educate
the public. The State has also
adopted a combined sewer overflow
policy that provides engineering
targets for cleanup and is presently
addressing several CSO abatement
projects.

Programs to Assess
Water Quality

    The Department of Environ-
mental  Protection (DEP) adopted a
watershed planning approach to
coordinate stream monitoring with
wastewater discharge permitting,
water withdrawal permitting, and
nonpoint source control on  a 5-year
rotating schedule. The DEP is also
adapting its monitoring strategies to
provide information on nonpoint
source pollution. For example, DEP
will focus more on wet-weather
sampling and biological monitoring
and less on chemical monitoring
during dry periods in order to gain
a more complete understanding of
the integrity of water resources.

    Very few lakes in Michigan
completely fail to support fishing
and swimming, but there is no
doubt that both point and nonpoint
sources have increased the rate of
eutrophication (overenrichment),
altered biological communities, and
degraded the overall aesthetic and
recreational quality of a great
number of Michigan's fragile lake
resources. Many more lakes are
threatened by long-term, cumula-
tive pollutant loads, especially in the
rapidly growing communities on
northern lower Michigan.
    Four of the five Great Lakes
border Michigan. The open waters
of Lakes Superior, Michigan, and
Huron have good quality. Poor
water quality is restricted to a few
degraded locations near shore. Lake
Erie's water quality has improved
dramatically in the last two decades.
Once declared dead, Lake Erie now
supports the largest walleye sport
fishery on the Great Lakes. The dra-
matic improvements are due prima-
rily to nutrient controls applied to
sewage treatment plants, particu-
larly in the  Detroit area.

Ground Water Quality

    Most of the ground water
resource is of excellent quality, but
certain aquifers have been contami-
nated with  toxic  materials leaking
from waste disposal sites, busi-
nesses, or government facilities. The
Michigan Ground Water Protection
Strategy and Implementation Plan
identifies specific program initiatives,

schedules, and agency responsibili-
ties for protecting the State's
ground water resources.

Programs to Restore
Water Quality

    Major point source reductions
in phosphorus and organic material
loads have reduced or eliminated
water quality problems in many
Michigan waters. However,
expanded efforts are needed to
control nonpoint source  pollution,
eliminate combined sewer over-
flows, and reduce toxic contamina-
tion. Michigan has implemented an
industrial pretreatment program,
promulgated rules on the discharge
of toxic substances, and  regulated
hazardous waste disposal facilities,
but many toxicity problems are due
to past activities that contaminated
sediments.

Programs to Assess
Water Quality

    Between 1989 and 1993, the
Department of Natural Resources
devoted a significant amount  of
staff time to documenting water
quality impacts from nonpoint
sources of pollution and verifying
information in the Michigan
Nonpoint Source Assessment.
Chemical, biological, and physical
surveys were conducted to  identify
water  quality standards violations
and degraded biological communi-
ties in numerous watersheds.

Surface Water Quality

    About 73% of the surveyed river
miles have good quality that fully
supports aquatic life uses and 39%
of the surveyed rivers fully support
swimming. Seventy-nine percent of
the surveyed lake acres fully support
swimming. The most common pol-
lutants identified in rivers were bac-
teria, oxygen-depleting substances,
pH (acidity), salinity/total dissolved
solids/chlorides, and metals. Non-
point sources generate most of the
pollution in rivers. Minnesota's 272
miles of Lake Superior shoreline have
fish consumption advisories. These
advisories recommend some limits
 on fish meals consumed for certain
 species and size classes. Most of the
 pollution originated from point
 sources has been controlled, but
 runoff (especially in agricultural
 regions) still degrades water quality.

 Ground Water Quality

    The State maintains a Ground
 Water Monitoring and Assessment
 Program to evaluate the quality of
 ground waters that supply domestic
 water to 70% of Minnesota's  popu-
 lation. The Program sampled  368
 wells in the southeastern and  south-
 western regions of the State during
 1992 and  1993. The samples  were
 analyzed for 43 inorganic param-
 eters and 68 volatile organic
 compounds. Monitoring detected
 nitrates in  62% of the wells and low
 levels of VOCs in 41 wells. Seven
 percent of the sampled wells
 contained  nitrate concentrations
 exceeding EPA's Maximum Con-
 taminant Level. Natural sources of
 manganese, iron, and arsenic  also
 interfere with uses of ground water.

 Programs to  Restore
 Water Quality

    During the 1994 reporting
 cycle, Minnesota revised its
 Nonpoint Source (NPS) Manage-
 ment Program with new strategies
for addressing agricultural sources,
forestry, urban runoff, contaminated
sediments, feedlots, mining, and
septic systems. The State also
revised strategies for monitoring and
assessing NPS impacts, educating
the public, implementing BMP';, and
applying the watershed protection
approach to NPS management.

    Minnesota adopted rules to
implement the State's Wetlands
Conservation Act and developed
wetlands water quality standards
during 1992 and 1993. The Wet-
land Conservation Act rules require
that local governments regulate
drain and fill activities in wetlands
that are not designated public
waters wetlands, which are listed on
the Protected Waters Inventory. The
rules allow the local governments to
grant one or more of 25  exemp-
tions for proposed activities on
smaller wetlands with less inunda-
tion.

Programs to Assess
Water Quality

    Minnesota maintains an Ambi-
ent Stream Monitoring Program
with 78 sampling stations. The State
also performs fish tissue sampling,
sediment monitoring, intensive sur-
veys, biological surveys, and lake
assessments and supports a citizen
lake monitoring  program.. In 1994,
the State completed  the Minnesota
River Assessment Project, a compre-
hensive study involving over 30
Federal, State, and local agencies.
The project incorporated intensive
biological monitoring and habitat
assessments with traditional chemi-
cal monitoring to identify multiple
sources and their impacts. A pilot
use support methodology was used
for rivers in the Minnesota River
basin that reflected this comprehen-
sive monitoring.

Surface Water Quality

    Mississippi reported that 81 % of
its surveyed rivers have fair water
quality that periodically does not
support aquatic life uses and
another 5% have poor water quality
that does not support aquatic life
uses. About 35% of the surveyed
rivers do not fully support swim-
ming. The most  common pollutants
identified in Mississippi's rivers
include nutrients, pesticides, silta-
tion, oxygen-depleting substances,
and bacteria. Agriculture is the most
common source  of pollution in
rivers, followed by municipal
sewage treatment plants.
    About 65% of the surveyed lake
acres have good  water quality that
fully supports aquatic life uses and
97% of the surveyed lake acres fully
support swimming. Nutrients, silt-
ation, pesticides, and oxygen-
depleting substances are the most
common pollutants in Mississippi
lakes. Agriculture is also the domi-
nant source of pollution  in
Mississippi's lakes.
    In estuaries, 74% of the sur-
veyed waters have good quality that
fully supports aquatic life uses, but
shellfishing activities are impaired in
all of the surveyed estuarine waters.
Bacteria and metals cause most of
the impacts observed in  estuaries.
High bacteria levels are associated
with shellfish  harvesting restrictions.
The  State attributes impacts in
estuarine waters to urban runoff/
storm sewers, septic systems, and
land disposal  activities.
    The State has posted six fish
consumption  advisories,  including
three commercial  fishing bans due
to elevated concentrations of PCBs,
PCP, and dioxins detected in fish
tissues.

Ground Water Quality

    Extensive contamination of
drinking water aquifers and public
water supplies remains uncommon
in Mississippi although localized
ground water contamination has
been detected at various facilities
across the State. The most fre-
quently identified  sources of con-
tamination  are leaky underground
storage tanks  and faulty septic: sys-
tems. Brine contamination is also a
problem near oil fields. Little ciata
exist for domestic wells that are
seldom sampled. Ground water
protection programs include the
Pesticide Container Recycling Pro-
gram, the Underground Storage
Tank Program, the Underground
Injection Control Program, the
Agrichemical Ground Water

head Protection Program (approved
by EPA in 1993).

Programs to Restore
Water Quality

    During 1993 and 1994, Missis-
sippi developed regulations for con-
ducting Section 401 Water Quality
Certifications. The regulations
enable the State to review Federal
licenses and permits for compliance
with State water quality standards.
The comprehensive regulations
went through public review and
were adopted in February 1994.
Mississippi also expanded its defini-
tion of waters of the State to
include wetlands and ground
waters.

Programs to Assess
Water Quality

    Each year, the State samples
about 25 of their 57 historical fixed
monitoring stations on a rotating
schedule. The State monitors physi-
cal and chemical parameters
bimonthly, metals in the water col-
umn twice a year, and biological
parameters once a year. The devel-
opment and implementation of a
rapid bioassessment methodology
has significantly increased coverage
of State waters beyond the historic
fixed stations. Several stations are
also sampled annually for metals
and pesticides in fish tissues. The
State monitoring program is supple-
mented by a network of 27 stations
operated by the USGS.

Surface Water Quality

    Almost half of Missouri's rivers
and streams  have impaired aquatic
habitat due to a combination of
factors, including natural geology,
climate, and agricultural land use.
As a result of these factors, many
streams suffer from low water
volume, low dissolved oxygen
concentrations, high water
temperatures, and excessive silt-
ation. In lakes, low dissolved oxygen
from upstream dam releases, taste
and odor problems,  and pesticides
are the most common ailments.
Agriculture, urban runoff, and reser-
voir releases are the  leading sources
of lake degradation.
   The Missouri Department of
Health advises that the public
restrict consumption of bottom-
feeding fish (such as catfish, carp,
and suckers) from non-Ozark
streams or lakes to 1 pound per
week due to high concentrations of
chlordane, PCBs, and other con-
taminants in these fish.

Ground Water Quality

   In general, ground water quan-
tity and quality increases from north
to south and west to east. Deep
ground water aquifers in northern
and western Missouri are not
suitable for drinking  water due to
high  concentrations  of natural min-
erals. Nitrates and, to a much lesser
extent, pesticides also contaminate
wells in this region. About one-third
of the private wells exceed drinking
water standards for nitrates, and
about 2% of private wells exceed
drinking water standards for either
atrazine or alachlor. Statewide, the
highest priority concerns include
ground water contamination from
septic tanks, feedlots and pasture-
land, and underground storage
tanks.

Programs to Restore
Water Quality

    Sewage treatment plant con-
struction has restored many surface
waters in Missouri, but overloaded
older facilities still impact about
62 stream miles. Nonpoint source
efforts  have been less successful at
restoring water quality. To date,  the
most successful activity has been the
reclamation of abandoned coal
mine lands, which is funded by a
tax on coal that generates $1 mil-
lion to $2 million annually. Stream
miles impacted by abandoned coal
mines fell from 100 miles to 42
miles as a result of reclamation
projects.

Programs to Assess
Water Quality

    Missouri's water quality moni-
toring  strategy features fixed-station
chemical sampling, short-term
intensive chemical surveys, rapid
visual/bioassessments, and detailed
biological monitoring to  advance
the development of biological crite-
ria. The State also conducts toxicity
testing and samples fish tissues for
toxic chemicals. During 1992-94,
four watershed projects featured
concentrated monitoring activities
designed to answer specific ques-
tions about animal waste manage-
ment and farm chemical  reduction
options.

ity that periodically fails to support
aquatic life uses. Another 5% have
poor water quality that consistently
fails to support aquatic life uses.
About 14% of the surveyed  lake
acres have good water quality that
fully supports fish and aquatic life,
57% fully support swimming, and
62% fully support drinking water
use. Agriculture (especially irrigated
crop production and rangeland)
impairs 60% of the surveyed stream
miles and 45% of the surveyed lake
acres. In general, nonpoint sources
are a factor in 90% of the impaired
rivers and 80% of the impaired
lakes. Resource extraction, forestry,
and municipal sewage treatment
plants have less widespread  impacts
on water quality.

Ground Water Quality

    More than 50% of Montanans
get their domestic water supply
from ground water sources.  Ground
water is plentiful and the quality is
generally excellent, but Monteina's
aquifers are very vulnerable to  pollu-
tion from human activities that will
expand as the population expands
throughout the river valleys. The
Department of Health and Environ-

watershed management programs.
To date, only 10% of the State's
stream miles and 2% of the lakes
have been assessed. Fixed-station
monitoring is limited to three of the
State's 16 river basins:  the Flathead
and upper and lower Clark Fork

that the U.S.  Geological Survey may
discontinue trend monitoring in

Surface Water Quality

    Agriculture is the most wide-
spread source of water quality prob-
lems in Nebraska, but urban runoff
also impacts the State's rivers and
streams. Agricultural runoff intro-
duces excess silt, bacteria, sus-
pended solids, pesticides, and nutri-
ents into surface waters. Municipal
and industrial facilities may contrib-
ute ammonia, bacteria, and metals.
Channelization and hydrologic
modifications have impacted aquatic
life in Nebraska streams by reducing
the diversity and availability of habi-
tat.
    Elevated concentrations of
metals, primarily arsenic, were the
most common water quality prob-
lem identified in lakes, followed by
siltation, low dissolved oxygen, and
nutrients. Pesticides, primarily
atrazine, also degraded 18 lakes.
Nebraska applies more atrazine to
crops than any other State in the
United States. Sources of pollution
in lakes include  municipal sewage
treatment plants, agriculture,  con-
struction, urban runoff, and hydro-
logic habitat modifications.

Ground Water Quality

    Although natural ground water
quality in Nebraska is good, hun-
dreds of individual cases of ground
water contamination have been
documented in  Nebraska and the
number of contaminated well:;
increases every year. Major sources
of ground water contamination
include agricultural activities, indus-
trial facilities, leaking underground
storage tanks, oil or hazardous sub-
stance spills, solid waste landfills,
wastewater lagoons, brine disposal
pits, and septic systems.

 consisted primarily of two federally
 funded demonstration projects on
 Long Pine Creek and Maple Creek.
 Now, Nebraska is evaluating the
 role of NPS pollution statewide. In
 1994, Nebraska supported 35 NPS
 projects throughout the State.
    Nebraska recently revised
 wetlands water quality standards to
 protect beneficial uses of aquatic
 life, aesthetics,  wildlife, and agricul-
 tural water supply. The State also
 protects wetlands with the water
 quality certification program, permit
 requirements for underground injec-
 tion activities and mineral explora-
 tion, and water quality monitoring.

 Programs to Assess
 Water Quality

    The State's Nonpoint Source
 Management Program cannot be
 effective without monitoring infor-
 mation  to identify and prioritize
 waters impacted by NPS, develop
 NPS control plans, and evaluate the
 effectiveness of implemented best
 management practices. In response
 to this need, Nebraska developed
 an NPS surface water quality moni-
toring strategy  to guide NPS moni-
toring projects. During 1992 and
 1993, the State conducted 100 NPS
screening assessments; 2 followup
 intensive NPS watershed assess-
 ments; BMP effectiveness studies in
 10 watersheds;  and a pesticide
 reconnaissance  survey in the Big
and Little Blue River Basin.

Surface Water Quality

    Only 10% (about 15,000 miles)
of Nevada's rivers and streams flow
year round, and most of these
waters are inaccessible. For this
reporting period, Nevada surveyed
1,440 miles of the 3,000 miles of
accessible perennial streams with
designated beneficial uses. Thirty
percent of the surveyed stream
miles have good water quality that
fully supports aquatic life uses; 18%
have fair water quality that some-
times does not support aquatic life
uses; and 52% have poor water
quality that does not support
aquatic life uses. Thirty-eight per-
cent of the surveyed streams fully
support swimming and 62% do  not
fully support swimming. In lakes,
29% of the surveyed acres fully
support aquatic life and swimming,
and 71 % partially support these
uses.
    Agricultural practices (irrigation,
grazing, and flow regulation) have
the greatest impact'on Nevada's
water resources. Agricultural sources
generate large sediment and nutri-
ent loads. Urban drainage systems
contribute nutrients, heavy metals,
and organic substances that deplete
oxygen. Flow reductions also have a
great impact on streams, limiting
dilution of salts, minerals, and
pollutants.

Ground Water Quality

    Nevada lacks comprehensive
ground water protection legislation,
but the State does have statutes
that control individual  sources of
contamination, including mining,
underground storage tanks, septic
systems, handling of hazardous
materials and waste, solid waste
disposal,  underground injection
wells, agricultural  practices, and
wastewater disposal. Land use
statutes also enable local authorities
to implement Wellhead Protection
Plans by adopting zoning ordi-
nances, subdivision regulations, and
site plan  review procedures. Local
authorities can implement certain
source control programs at the local
level.

Programs to Restore
Water Quality

    Nevada's Nonpoint Source
Management Plan aims to reduce
NFS pollution with interagency
coordination, education programs,
and incentives that encourage vol-
untary installation of best manage-
ment practices. During 1992-1994,
the State continued updating the
Handbook of Best Management Prac-
tices and supported  NPS assessment
activities in each of the State's six
major river basins. The State also
completed a Wellhead Protection
Plan for the State and began devel-
oping a State Ground Water Protec-
tion Policy.

Programs to Assess
Water Quality

    Several State, Federal, and local
agencies regularly sample chemical
and physical parameters  at over
100 sites in the 14 hydrologic
regions of the State. Nevada hopes
to add biological monitoring at
several routine sampling  sites after
the State adapts rapid bioassess-
ment protocols to the arid condi-
tions in Nevada. The State also
coordinates intensive field studies on
Nevada's major river systems, the
Truckee River Basin,  Carson River
Basin, Walker River Basin, and the
Humboldt River Basin. The State
also monitors a number of lakes and
reservoirs in conjunction  with the
Section 314 Clean Lakes  Program.

                                     Overall, the quality of New
                                  Hampshire's surface waters is excel-
                                  lent. Over 99% of the State's river
                                  miles and 95% of the lake acres
                                  have excellent or good water quality
                                  that fully supports aquatic life uses
                                  and swimming. Poor water quality
                                  conditions are more widespread in
                                  estuaries; high bacterial levels inter-
                                  fere with shellfish harvesting in 66%
                                  of the estuarine waters. Bacteria is
                                  also the leading cause of impair-
                                  ment in rivers where  high bacteria
levels indicate unsafe swimming
conditions. Nutrients are the major
cause of impairment in lakes and
ponds. The State suspects that
nonpoint sources are responsible for
most of the pollution entering the
State's waters.
    New Hampshire advises the
public to restrict consumption of
fish caught in the Androscoggin
River below Berlin, the Connecticut
River, Horseshoe Pond, and the:
Great Bay Estuary.  One fish con-
sumption advisory is posted on the
Androscoggin River below Berlin
due to elevated concentrations of
dioxins in fish tissue. The James
River Corporation paper mill in Ber-
lin is the  suspected source of the
dioxins.

Ground Water Quality

    New Hampshire's overall
ground water quality is very good.
In some localized areas, naturally
occurring arsenic, fluoride, and
radionuclides (principally radon)
exceed drinking water standards.
Releases from petroleum facilities,
industrial operations, and landfills
have contaminated isolated areas
with petroleum or volatile organic
compounds. Sodium is the only
contaminant that has exhibited an
increasing presence in ground water
due to the widespread application
of road salts in winter. New  Hamp-
shire is developing a Comprehensive
State Ground Water Protection Pro-
gram to coordinate their various
ground water assessment,  preven-
tion, and restoration programs.

Programs to Restore
Water Quality

    Over the past 20 years, New
Hampshire has eliminated or abated
all significant untreated municipal
and industrial wastewater discharges
in State waters. Recently, the
Department of Environmental Ser-
vices (DES) initiated a watershed
protection approach to identify and
resolve remaining pollution prob-
lems.  DES will compile watershed
maps and land use data, identify
major sources of pollution, model
total maximum daily  loads for pol-
lutants,  and  revise discharge permits
as needed in the State's five basins.
DES estimates that each basin
assessment will require 2 years to
complete at current funding levels.

Programs to Assess
Water Quality

    DES implemented a rotating
watershed monitoring program in
1989. In 1993, the rotation was
temporarily halted so that the State
could intensify monitoring at sites
violating standards. During 1994
and 1995, DES will investigate
sources  of violations confirmed  by
the 1993 data.

                                  waters. Bacteria (which indicates
                                  unsafe swimming conditions) and
                                  nutrients are the most common
                                  pollutants in rivers and streams. All
                                  of the State's lakes are believed to
                                  be threatened or actively deteriorat-
                                  ing. Bacterial contamination is the
                                  most widespread problem  in estuar-
                                  ies, impairing both shellfish harvest-
                                  ing and swimming. Other  problems
include nutrients, low dissolved
oxygen concentrations, pesticides,
and priority organic chemicals. Ma-
jor sources impacting New Jersey's
waters include municipal treatment
plants, industrial facilities, combined
sewers, urban runoff, construction,
agriculture, and land disposal of
wastes (including septic tanks).

Ground Water Quality

   There are currently over 6,000
ground water pollution investiga-
tions under way in New Jersey. The
most common pollutants found in
ground water are volatile organic
compounds,  metals, base neutral
chemicals, acid-extractable chemi-
cals, PCBs, and pesticides. Under-
ground storage tanks are the most
common source of ground water
contamination, followed by landfills,
surface spills, and industrial/com-
mercial septic systems. New Jersey
adopted new ground water quality
standards in  1993 that revise the
ground water classification system
and establish numerical criteria for
many pollutants. The standards also
protect good ground water quality
from degradation by future
activities.

Programs to Restore
Water Quality

   New Jersey's Department of
Environmental Protection (DEP) is
adopting a watershed approach to
water quality and quantity manage-
ment. The watershed approach
coordinates monitoring, modeling,
planning, permitting, and
enforcement activities within a
geographic area that drains into a

    major river, lake, or estuary. The
watershed approach allows all inter-
ested parties to participate in the
development of consensus-based
management options. DEP is
currently conducting a watershed
protection pilot project in the
Whippany River watershed with
local governments,  permittees,
regional interest groups, and private
citizens.

Programs to Assess
Water Quality

    DEP's current monitoring pro-
gram is centered  around physical
and chemical sampling at fixed
stations designed to monitor long-
term trends. Unfortunately, the
fixed-station network cannot pro-
vide data to address other manage-
ment needs, such as identifying
specific sources of pollution  and
measuring the effectiveness  of spe-
cific pollution control actions. There-
fore, DEP recommends supplement-
ing the fixed-station monitoring
program with intensive watershed
surveys to support watershed pro-
tection management projects. Inten-
sive surveys would collect data to
profile water quality over 24-hour
periods, identify pollution sources,
quantify pollution impacts, compare
water quality data to flow condi-
tions, model wasteload allocations,
and determine assimilative capacity
of waterbodies.

Surface Water Qualify

    About 93% of New Mexico's
surveyed stream miles have good
water quality that fully supports
aquatic life uses. Ninety-nine percent
of the surveyed river miles fully sup-
port swimming. The leading prob-
lems in streams include habitat alter-
ations (such as removal of stream-
side vegetation), siltation, metals,
and nutrients. Nonpoint sources are
responsible for over 93% of the
degradation in New Mexico's 3,255
impaired stream miles. Municipal
wastewater treatment plants impair
about 4% of the degraded waters
(124 stream miles).
    Agriculture and recreational
activities are the primary sources of
nutrients, siltation, reduced shore-
line vegetation, and bank destabili-
zation that impairs aquatic life use
in 91% of New Mexico's surveyed
lake acres. Mercury contamination
from unknown sources appears in
fish caught at 22 reservoirs. How-
ever, water and sediment samples
from surveyed lakes and reservoirs
have not detected high concentra-
tions of mercury. Fish may contain
high concentrations of mercury in
waters with minute quantities of
mercury because the process of
biomagnification concentrates
mercury in fish tissue.

Ground Water Quality

    About 88% of the population of
New Mexico depends on ground;
water for drinking water. The Envi-
ronment  Department has identified
at least 1,745 cases of ground water
contamination since 1927. The
most common source of ground
water contamination is small house-
hold septic tanks and cesspools.
Leaking underground storage tanks,
injection wells, landfills, surface
impoundments, oil and gas produc-
tion, mining and milling, dairies, .
and miscellaneous industrial sources
also contaminate ground water in
New Mexico. New Mexico operates
a ground water discharger permit
program that includes ground water
standards for intentional discharges
and a spill cleanup provision for
other discharges.

Programs to Restore
Water Quality

    New Mexico's Nonpoint Source
Management Program contains a
series of implementation milestones
that were designed to establish
goals while providing a method to
measure progress and success of the
program. Implementation  consists
of the coordination of efforts among
NPS management agencies, promo-
tion and implementation of best
management practices, coordination
of watershed projects, inspection
and enforcement activities, consis-
tency reviews, and education and
outreach  activities.

Programs to Assess
Water Quality

    New Mexico relies heavily on
chemical  and physical data to assess
water quality. Fish tissue data
became available in 1991, and data
from biological surveys and bioassay
tests were incorporated into the
1994 assessments where possible.
The State also conducts extensive
monitoring to determine the
effectiveness of best management
practices  implemented under the
Nonpoint Source Management
Program. During the current 305(b)
reporting cycle,  New Mexico com-
pleted two special water quality
surveys along the Rio Hondo and
the Red River in Taos County.

Surface Water Quality

    Ninety-one percent of New
York's rivers and streams, 74% of
the State's lake acres, 97% of the
State's Great Lakes shoreline, and
99% of the bays and tidal waters
have good water quality that fully
supports aquatic life uses. Swimming
is fully supported in 99% of the
surveyed rivers, 78% of the surveyed
lakes, 80% of the Great Lakes shore-
line, and 93% of the surveyed estua-
rine waters. Eighty-five  percent of
New York's Great Lake's shoreline
does not fully support fish con-
sumption use because of a fish
consumption advisory.
    Agriculture is a major source of
nutrients and silt that impair New
York's rivers, lakes, and reservoirs.
Hydrologic modification and habitat
modification are also a major source
of water quality impairment in rivers
and lakes. Urban runoff is a major
source of pollution in the State's
estuaries. Bacteria from urban runoff
and other sources close about
200,000 acres (16%) of potential
shellfishing beds.
    Contaminated sediments are
the primary source of 7% of the
impaired rivers and lakes, 76% of
the impaired Great Lake's shoreline,
and 27% of the impaired estuarine
waters in New York State. Sedi-
ments are contaminated with PCBs,
chlorinated  organic pesticides, mer-
cury, cadmium, mirex, and dioxins
that bioconcentrate in the food
chain and result in fish consumption
advisories.
    Sewage treatment plant con-
struction and upgrades have had a
significant impact on water quality.
Since 1972, the size of rivers
impacted by municipal sewage
treatment facilities has declined
from about 2,000 miles to 300
miles.

Ground  Water Quality

    About 3% of the State's public
water supply system  wells (160
wells) are closed or abandoned due
to contamination from organic
chemicals. The most common
contaminants are synthetic solvents

and degreasers, gasoline and other
petroleum products, and agricultural
pesticides and herbicides (primarily
aldicarb and carbofuran). The most
common sources of organic solvents
in ground water are spills, leaks, and
improper handling  at industrial and
commercial facilities.

Programs to Restore
Water Quality

    Virtually every county of the
State has a county  water quality
coordinating committee composed
of local agencies  (such as Cornell
Cooperative Extension and soil and
water conservation  districts), local
representatives from State and
Federal agencies, and public interest
groups. The county committees
meet regularly to discuss local priori-
ties and fashion  local strategies to
address nonpoint source pollution.

Programs to Assess
Water Quality

    In 1987, New York State imple-
mented the Rotating Intensive Basin
Studies (RIBS), an ambient monitor-
ing program that concentrates
monitoring activities on one-third
of the State's hydrologic basins for
2-year periods. The DEC monitors
the entire State every 6 years.
Intensive monitoring clarifies cause-
and-effect relationships between
pollutants and water quality,
measures the effectiveness of imple-
mented pollution controls, and
supports regulatory decisions.

Surface Water Quality

    About 70% of the State's sur-
veyed freshwater rivers and streams
have good water quality that fully
supports aquatic life uses, 25% have
fair water quality that partially sup-
ports aquatic life uses, and 5% have
poor water quality that does not
support aquatic life uses. Eighteen
percent of the surveyed rivers do
not fully support swimming. The
major sources of impairment are
agriculture (responsible for 56% of
the impaired river miles), urban
runoff (responsible for 13%), point
sources (responsible for 12%), and
construction (responsible for 11 %).
 These sources generate siltation,
 bacteria, and organic wastes that
 deplete dissolved oxygen.
    Only 3% of the surveyed lakes
 in North Carolina are impaired for
 swimming and aquatic life uses. A
 few lakes are impacted by dioxin,
 metals, and excessive nutrient
 enrichment. The Champion Paper
 mill on the Pigeon River is the
 source of dioxin contamination in
 Waterville Lake. The State and the
 mill implemented a dioxin minimi-
 zation program in the mid-1980s
 and completed a modernization
 program in 1993 that will reduce
 water usage and discharges.
    About 93% of the estuaries and
 sounds in North Carolina fully sup-
 port designated uses.  Agriculture,
 urban runoff, septic tanks, and point
 source discharges are  the leading
 sources of nutrients, bacteria,  and
 low dissolved oxygen  that degrade
 estuaries.

 Ground  Water Quality

    About half of the  people in
 North Carolina use ground water as
 their primary supply of drinking
 water. Ground water quality is
 generally good, but new cases of
 ground water contamination
 affected 276 public water supplies
 during 1992-1993. The leading
 source of ground water contamina-
 tion is leaking underground storage
 tanks,  which contaminate ground
 water  with gasoline, diesel fuel, and
 heating oil. During 1992 and  1993,
 North Carolina  adopted new regula-
tions for administering Leaking
 Underground Storage  Tank funds
and amended ground water
standards.

Programs to Restore
Water Quality

    In 1992-1993,  North Carolina
continued its aggressive  program to
control nonpoint source  pollution.
North Carolina adopted  a
nondischarge rule for animal waste
management, implemented an
innovative nutrient trading program
between point and nonpoint
sources in the Tar-Pamlico  river
basin, signed 2,500 new contracts
under the Agricultural Cost Share
Program to implement best man-
agement practices, and reclassified
about 200 water supply  watersheds
for special protection.

Programs to Assess
Water Quality

    Surface water quality in North
Carolina was primarily evaluated
using physical and chemical data
collected by the Division of Environ-
mental Management (DEM) from a
statewide fixed-station network and
biological assessments. These
include macroinvertebrate  (aquatic
insect) community surveys, fish
community structure analyses,
phytoplankton analyses,  bioassays,
and limnological review  of lakes and
watersheds.  Other sources of infor-
mation were point source  monitor-
ing data, shellfish closure reports,
lake trophic state studies, and
reports prepared by other  local,
State, and Federal  agencies.

Surface Water Quality

    North Dakota reports that 78%
of its surveyed rivers and streams
have good water quality that fully
supports aquatic life uses now, but
good conditions are threatened in
most of these streams. Eighty-nine
percent of the surveyed streams
fully support swimming. Elevated
siltation, nutrients, ammonia, patho-
gens, oxygen-depleting wastes, and
habitat alterations impair aquatic life
use support in 22% of the surveyed
rivers and impair swimming in 11 %
of the surveyed rivers. The leading
 sources of contamination are agri-
 culture, removal of streamside veg-
 etation, municipal sewage treatment
 plants, and other habitat alterations.
 Natural conditions, such as low
 flows, also contribute to violations
 of standards.
    In  lakes, 95% of the surveyed
 acres have good water quality that
 fully supports aquatic life uses, and
 98% of the surveyed  acres fully
 support swimming. Siltation,  nutri-
 ents, oxygen-depleting substances,
 and suspended solids are the most
 widespread pollutants in North
 Dakota's lakes. The leading sources
 of pollution in lakes are agricultural
 activities (including nonirrigated
 crop production, pasture land, irri-
 gated crop production,  and feed-
 lots), municipal sewage treatment
 plants, and urban runoff/storm sew-
 ers. Natural conditions also prevent
 some waters from fully supporting
 designated uses.

 Ground Water Quality

    North Dakota has not identified
 widespread ground water contami-
 nation, although some naturally
 occurring compounds may make
 the quality of ground water undesir-
 able in a few aquifers. Where
 human-induced ground water con-
 tamination has occurred, the
 impacts have been attributed  prima-
 rily to petroleum storage facilities,
 agricultural storage facilities,
feedlots, poorly designed wells,
 abandoned wells, wastewater
treatment lagoons, landfills, septic
systems, and the underground
 injection of waste. Assessment and
 protection of ground water

water quality monitoring activities,
the implementation of wellhead
protection projects, the Compre-
hensive Ground Water Protection
Program, and the development of a
State Management Plan for Pesti-
cides.

Programs to Restore
Water Quality

    North Dakota's Nonpoint
Source Pollution Management Pro-
gram has provided financial support
to 26 projects over the past 4 years.
Although the size, type, and target
audience of these projects vary, the
projects share the same basic goals:
(1) increase public  awareness
of nonpoint source pollution,
(2) reduce  or prevent the delivery
of NPS pollutants to waters of the
State, and (3) disseminate informa-
tion on effective solutions to NPS
pollution.

Programs to Assess
Water Quality

    The North Dakota Department
of Health monitors physical and
chemical parameters (such as dis-
solved oxygen,  pH, total dissolved
solids, and nutrients), toxic contami-
nants in fish, whole effluent toxicity,
and fish community structure.

Surface Water Quality

    Ohio based their 1994 assess-
ments on data collected between
1988 and  1994. Ohio's assessment
methods compare observed eco-
logical characteristics (including
data on aquatic insects, fish species,
habitat,  and  streamside vegetation)
with background conditions found
at least-impacted reference sites for
a given  ecoregion and stream type.
    Ohio identified ecological
impacts from organic enrichment
and low dissolved oxygen concen-
trations, siltation, habitat modifica-
tion, metals, ammonia, and flow
alterations. Fecal coliform bacteria
indicate impaired swimming condi-
tions in 9% of the surveyed river
miles. These impacts stem from
municipal discharges, runoff from
agriculture, hydromodification,
industrial discharges, mining, urban
runoff, and combined  sewer over-
flows.
    Ohio estimates that wastewater
treatment plant construction and
upgrades have restored aquatic life
to about 1,000 river miles since the
1970s. Since 1988, the percentage
of surveyed river miles fully fit for
swimming also grew from 49% to
60%. However, increasing threats
from nonpoint sources could erode
gains made with point source
controls and slow the rate of
restoration.
    The most common impacts on
Ohio lakes include nutrients, volume
loss due to sedimentation, organic
enrichment, and habitat alterations.
Nonpoint sources, including agricul-
ture, urban runoff, and septic
systems, generate most of these
impacts. However, municipal point
sources still affect 63% of the sur-
veyed lake acres.
    Most of the Lake Erie shoreline
is fit for recreational use, but a fish
consumption advisory for channel
catfish and carp remains in effect
along the entire shoreline. Ohio also
issued fish consumption advisories
for all species of fish caught on 137
river miles and documented
elevated levels of PCBs in fish
caught at two small lakes.

Ground Water Quality

    About 4.5 million Ohio residents
depend upon wells for domestic
water. Waste disposal activities,
underground storage tank leaks,
and spills are the dominant sources
of ground water contamination in
Ohio.

Programs to Restore
Water Quality

    To fully restore water quality,
Ohio  EPA advocates an ecosystem
approach that confronts degrada-
tion on shore as well as in the
water. Ohio's programs aim to cor-
rect nonchemical impacts, such as
channel modification and the
destruction of shoreline vegetation.

Programs to Assess
Water Quality

    Ohio pioneered the integration
of biosurvey data, physical  habitat
data,  and bioassays with water
chemistry data to measure the over-
all integrity of water resources. Bio-
logical monitoring  provides the
foundation of Ohio's water pro-
'grams because traditional chemical
monitoring alone may not detect
episodic pollution events or non-
chemical impacts. Ohio EPA found
that biosurvey data can  increase the
detection of aquatic life use impair-
ment by about 35% to 50%.

                                  State's rivers and streams, followed
  by petroleum extraction and hydro-
  logic/habitat modifications.
     Fifty-seven percent of the
  surveyed lake acres fully support
  aquatic life uses and 60% fully sup-
  port swimming. The most wide-
  spread pollutants in Oklahoma's
  lakes are siltation, nutrients, sus-
  pended solids, and  oxygen-deplet-
  ing substances. Agriculture is also
 the most common source of pollu-
 tion in lakes, followed by contami-
 nated sediments and flow regula-
 tion.  Several lakes are impacted by
 acid mine drainage, including the
 Gaines Creek arm of Lake Eufaula
 and the Lake O' the Cherokees.

 Ground  Water Quality

    Ambient ground water monitor-
 ing has detected elevated nitrate
 concentrations in monitoring wells
 scattered across the State. Monitor-
 ing has also detected isolated -cases
 of hydrocarbon contamination,
 elevated selenium and fluoride con-
 centrations (probably due to natural
 sources), chloride contamination
 from discontinued oil field activities,
 metals from past mining operations,
 and gross alpha activity above maxi-
 mum  allowable limits.  Industrial
 solvents contaminate a few sites
 near landfills, storage pits, and
Tinker Air Force Base. The State
 rates agriculture, injection wells,
septic tanks, surface  impoundments,
and industrial spills as the highest
priority sources of ground water
contamination.

Surface Water Quality

    Forty-three percent of Oregon's
surveyed rivers have good water
quality that fully supports desig-
nated uses,  30% have fair water
quality that partially supports uses,
and 27% have poor water quality
that does not support uses. The
most widespread problems in
Oregon's streams are habitat alter-
ations, high temperatures, and silt-
ation from grazing, other agricul-
tural activities, forestry, and recre-
ation.
   In lakes, 74% of the surveyed
acres fully support uses, 12%
 partially support uses, and 14% do
 not support uses. The most com-
 mon  problems in Oregon's lakes are
 excess nutrients, pH (acidity), and
 low dissolved oxygen. DEQ suspects
 that agriculture and natural condi-
 tions  (including shallow depth and
 high evaporation rates) are the most
 significant sources of lake problems.
    Six percent of Oregon's estua-
 rine waters have good quality and
 94%  have fair water quality due to
 periodic violations of bacteria stan-
 dards. High concentrations of fecal
 bacteria usually result from bypasses
 at municipal wastewater treatment
 plants during rainfall events or
 improper management of animal
 wastes.

 Ground Water Quality

    Monitoring  has detected
 nitrates, benzene, other volatile
 organic compounds, bacteria, herbi-
 cides, and pesticides in ground
 water. Suspected sources include
 septic systems, agriculture, highway
 maintenance, industry, and com-
 merce. During 1992 and 1993,
 DEQ conducted statewide ground
 water monitoring, developed a
 ground water data management
 system, and issued 16 grants for
 research and education projects
 designed to protect ground water
 from nonpoint sources of pollution.

the Watershed Health Program,
field-based technical teams work
closely with watershed councils
composed of local residents and
stakeholders to set priorities and
fund projects. DEQ and other State
agencies targeted the Grand Ronde
Basin and the combined South
Coast and Rogue Basins to begin
implementing the Watershed Health
Program with $10 million in State
funds for  1994 and 1995. These
basins  were selected because of
existing Total Maximum Daily Load
programs.

Programs to Assess
Water  Quality

    DEQ  routinely monitors about
3,500  miles  of streams in its ambi-
ent river monitoring program. These
streams receive about 90% of the
wastewater discharged by point
sources throughout the State. Dur-
ing 1992 and 1993, DEQ increased
the number of ambient river moni-
toring stations and expanded other
monitoring programs, including
ground water studies, continuous
monitoring, mixing zone studies,
and bioassessments. Recently,
Oregon also initiated the Coos Bay
toxics study, the Tillamook Bay
National  Estuary Program, and the
Lower Columbia River Bi-State Pro-
gram to provide more information
on estuarine water quality.

 Surface Water Quality

    Over 81 % of the surveyed river
 miles have good water quality that
 fully supports aquatic life uses and
 swimming. About 8% have fair
 water quality that partially supports
 these uses, and 11 % have poor
 water quality that does not support
 aquatic life uses and swimming. The
 most widespread pollutants are
 metals, which impact over 2,092
 miles. Pollutants identified less
frequently include suspended solids
 (impacting 603 miles), nutrients
 (impacting 586 miles), and pH
 (impacting 273 miles).
    Abandoned mine drainage is
the most significant source of
 surface water quality degradation in
 Pennsylvania. Drainage from mining
 sites pollutes at least 2,404 miles of
 streams representing 52% of all
 degraded streams in the Common-
 wealth. Other sources of degrada-
 tion include agriculture (impacting
 694 miles), municipal sewage treat-
 ment plants (impacting 241 miles),
 and industrial point sources (impact-
 ing 206 miles).
   . Pennsylvania has issued fish
 consumption advisories on 23
 waterbodies.  Most of the advisories
 are due to elevated  concentrations
 of PCBs and chlordane in fish tissue,
 but a few advisories have been
 issued for mirex and mercury. In
 1994, the State deactivated two
 advisories for dioxins on Codurus
 Creek and the South Branch of
 Codurus Creek as well as one advis-
 ory for chlordane on the Delaware
 River.

 Ground Water Quality

    Major sources of ground water
 contamination in Pennsylvania
 include  leaking underground stor-
 age tanks, containers from hazard-
 ous materials  facilities, and improper
 handling or overuse of fertilizer.
 Petroleum and petroleum byprod-
 ucts are the most common pollut-
 ants in ground water. Coal mining
 and oil and gas production have
 also elevated concentrations of sev-
 eral elements  (including chlorides,
 iron, barium, and strontium) in
 some regions  of the  Common-
 wealth. A Ground Water Quality

    Eliminating acid mine drainage
from abandoned mines will require
up to $5 billion. The cost, difficulty,
magnitude, and extent of the prob-
lem have hampered progress. To
date, the Commonwealth has
funded studies to determine the
effectiveness of alternative tech-
niques for treating mine drainage
and preventing contamination. The
U.S. Department of Agriculture
(USDA) Natural Resources Conserva-
tion Service's Rural Abandoned
Mines Program also reconstructs
abandoned mine sites in Pennsyl-
vania.

Programs to Assess

    The Water Quality Network
monitors chemical and physical
parameters almost monthly and
biological  parameters annually at
168 fixed  stations on rivers, streams,
and Lake Erie. In 1991, Pennsylvania
began annual sampling at 15 to 20
lakes for 5 years. After 5 years,
another set of lakes will be sampled
annually for 5 years until 90 lakes
have been monitored. The Com-
monwealth also conducts ambient
ground water monitoring at 537
monitoring sites.

Surface Water Quality

    In rivers and streams, 17% of
the surveyed miles have good water
quality that fully supports aquatic life
uses, 32% partially support aquatic
life uses, and 51% do not support
aquatic life uses. Swimming is
impaired in 79% of the surveyed
rivers and streams. Low dissolved
oxygen, pesticides, flow alteration,
bacteria, and nutrients are the most
widespread problems in rivers and
streams. In lakes, 30% of the sur-
veyed acres fully support aquatic life
uses, 19% partially support these
 uses, and 51% do not support
 aquatic life uses. Swimming is
 impaired in 55% of the surveyed
 lake acres. Uses are impaired by
 inorganic chemicals, low dissolved
 oxygen concentrations, bacteria,
 priority organic chemicals, metals,
 and pesticides.
    Only 16% of the assessed estua-
 rine waters fully support aquatic life
 uses and only 17% fully support
 swimming due to oxygen-depleting
 organic substances, bacteria, and
 habitat alterations. Land disposal of
 wastes, urban runoff, agriculture,
 municipal sewage treatment plants,
 and natural conditions are the most
 common sources of water quality
 degradation in rivers, lakes, and
 estuaries. Industrial and municipal
 discharges also pollute beaches.

 Ground Water Quality

    Organic compounds,  including
 dichloromethane,  1,1,2-trichloro-
 ethane, and toluene were detected
 below maximum contaminant levels
 in several wells. Four wells were
 closed due to bacterial contamina-
 tion and high turbidity and two
 wells were shut down due to con-
 tamination from volatile organic
 compounds. The major sources of
 ground water contamination eire
 septic tanks, livestock operations,
 agriculture, storage tanks,  and land-
fills. Puerto Rico adopted ground
water use classifications and  water
 quality standards in 1990. In 1993,
the Environmental Quality Board
completed the ground water prior-
ity list that ranks critical areas for
remediation and protection
activities.

    Puerto Rico requires permits or
certificates for ground water and
surface water discharges, under-
ground storage tanks, and livestock
operations. Certificates require live-
stock operations to implement ani-
mal waste management systems
and other best management prac-
tices. During the 1992-1993 report-
ing period, Puerto Rico issued 194
certificates for livestock operations;
inspected 427 livestock operations;
implemented 77 BMPs in priority
watersheds; offered 15 conferences
to educate the public about
nonpoint source pollution and con-
trols; and monitored  the effective-
ness of BMPs implemented at poul-
try, dairy, and hog farms.

Programs to Assess
Water Quality

    Under a cooperative agreement
with the  government of Puerto Rico,
the USGS collects bimonthly
samples at 57 fixed surface water
monitoring stations. The samples
are analyzed for dissolved oxygen,
nutrients, bacteria, and conventional
parameters. Twice a year, the
samples are analyzed for metals  and
several toxic substances. Puerto Rico
also maintains a Permanent Coastal
Water Quality Network of 88 sta-
tions and the San Juan Beachfront
Special Monitoring Network of 22
stations sampled monthly for bacte-
rial contamination.

Surface Water Quality

    Eighty-four percent of Rhode
Island's rivers, 81 % of lakes, and
96% of estuarine waters support
aquatic life uses. However, many of
these waters are considered threat-
ened. About 80% of rivers, 94% of
lakes, and 93% 6f estuaries fully
support swimming. The most signifi-
cant pollutants in Rhode Island's
waters are heavy metals (especially
copper and lead), priority organic
chemicals (PCBs), bacteria, low dis-
solved oxygen, excess nutrients, and
low pH/low buffering capacity.
Recurring algae blooms, high nutri-
ents, and high turbidity threaten the
use of several surface waters for
drinking water supplies.
    Rivers and estuaries are
impacted by industrial and munici-
pal discharges, combined sewer
overflows, urban runoff, highway
runoff, failed septic systems, and
contaminated sediments. Lakes are
primarily impacted by nonpoint
sources, including septic systems,
atmospheric deposition, and land
and road runoff.

Ground  Water Quality

    About 24% of the State's popu-
lation is supplied with drinking
water from  public and private wells.
Overall,  Rhode Island's ground
water has good to excellent quality,
but over 100 contaminants have
been detected in localized areas.
Twenty-one community and eight
noncommunity wells have been
closed and 400 private wells have
required treatment due to contami-
nation. The most common pollut-
ants are petroleum products, certain
organic solvents, and nitrates. Sig-
nificant pollution sources include
leaking underground storage tanks,
hazardous and industrial waste  dis-
posal sites, illegal or improper waste
disposal, chemical and oil spills,
landfills, septic systems, road salt
storage and application, and fertil-
izer application.

Surface Water Quality

    Ninety-one percent of surveyed
rivers, 99% of surveyed lakes, and
75% of estuaries have good water
quality that fully supports aquatic
life uses. Sixty-three percent of
rivers, 99% of lakes, and 86% of
estuaries fully support swimming.
Unsuitable water quality is respon-
sible for shellfish harvesting prohibi-
tions in only 2% of the State's
coastal shellfish waters. Another
11 % of shellfish waters are closed as
a precaution due to potential pollu-
tion from nearby marinas or point
source discharges.
    Bacteria are the most frequent
cause of impairment (i.e., partial or
nonsupport of designated uses) in
rivers and streams; metals are the
most frequent cause of impairment
in lakes, but only 1% of lakes do
not fully support uses; and low dis-
solved oxygen is the most frequent
cause of impairment in estuaries.
Toxic contaminants do not appear
to be a widespread problem in
South Carolina surface waters. Of all
waters assessed, only 5% had ele-
vated levels of metals and only 3%
had concentrations of PCBs, pesti-
cides, and organics above the
assessment criteria.

Ground Water Quality

    Overall ground water quality
remains excellent, although  the
number of reported ground water
contamination cases rose from 60
cases in 1980 to 2,207 cases in
1993. The.increase in the number
of contaminated sites is primarily
due to expanded monitoring at
underground storage tank sites.
Leaking underground storage tanks
are the most common source of
contamination, impacting 1,741
sites, followed by leaking pits,
ponds, and lagoons.

    Seventeen percent of South
Dakota's surveyed rivers and streams
fully support aquatic life uses and
83% do not fully support aquatic
life uses. Thirty-five percent of the
surveyed rivers also support swim-
ming, and 65% of the surveyed
rivers do not fully support swim-
ming. The most common pollutants
impacting South Dakota streams are
suspended solids due to water ero-
sion from croplands, gully erosion
from rangelands, streambank
erosion, and other natural forms of
erosion. Ninety-eight percent of
South Dakota's surveyed lake acres
fully support aquatic life uses now,
but the quality of these lakes is
threatened. Similarly, 100% of the
surveyed lake acres fully support
swimming, but these waters are
threatened. The most common
pollutants in lakes are nutrients and
sediments from agricultural runoff.
    The high water conditions that
prevailed in South Dakota for most
of this reporting period greatly
increased watershed  erosion and
sedimentation in  lakes and streams.
Suspended solids criteria were
severely violated in many rivers and
streams, and there was an increase
in the incidence of fecal coliform
bacteria in swimming areas at lakes.
However, water quality improved in
some lakes that experienced low
water levels during the late 1980s,
and high flows diluted bacteria in
rivers and streams.

miles. Toxic materials, bacteria, and
flow alterations impact rivers to a
lesser extent. Major sources of
pollutants include agriculture,
hydromodification, and municipal

mining occur in the Cumberland
Plateau region, and poor quality
water discharged from dams
impacts streams in east and middle
Tennessee.
    In lakes, 421,407 acres (78%)

due to severe pollution. The nnost
widespread problems in lakes in-
clude nutrients, low dissolved oxy-

Major sources of these pollutants
are agriculture, municipal waste-

    Fish consumption advisories are
posted  on 142 miles of rivers  and

not support aquatic life uses.
Ninety-nine percent of the surveyed
lake acres fully support swimming.
The most common problems in
reservoirs are low dissolved oxygen
and elevated bacteria concentra-
tions. Major sources that contrib-
uted to nonsupport of uses include
unknown sources, natural sources
(such as high temperature and shal-
low conditions), municipal sewage
treatment plants, and industrial
point sources.
    The leading problem in estuar-
ies is bacteria from unknown
sources that contaminate shellfish
beds. Fifty-nine percent of the sur-
veyed estuarine waters fully support
shellfishing use, 8% partially support
this use, and 33% do not support
shellfishing.

Ground Water Quality

    About 44% of the municipal
water is obtained from ground
water in Texas. Natural contamina-
tion affects the quality of more
ground water in the State than all
other sources of contamination
combined. Natural leaching from
the aquifer matrix can elevate min-
erals,  metals, and radioactive sub-
stances in ground water. The most
common ground water contami-
nants from human activities are
gasoline, diesel, and other petro-
leum products. Less common con-
taminants include volatile organic
compounds and pesticides.

Programs to Restore
Water Quality

    The Texas Natural Resource
Conservation Commission (TNRCC)
launched a basin approach to water
resource management with the
Clean Rivers Program (CRP). The
CRP is a first step in the develop-
ment of a long-term, comprehen-
sive and integrated geographic
management approach aimed at
improving coordination of natural
resource functions in the agency.
The basin approach will provide  a
framework for identifying problems,
involving stakeholders, and integrat-
ing actions. The basin approach  also
allows for the use of risk-based tar-
geting to prioritize  issues and better
allocate finite public resources.

Programs to Assess
Water Quality

    The TNRCC samples about 700
fixed stations as part of its Surface
Water Quality Monitoring Program
(SWQMP). The TNRCC samples
different parameters and varies the
frequency of sampling at each site
to satisfy different needs. The
TNRCC also conducts  intensive
surveys  to evaluate potential
impacts from point source discharg-
ers during low flow conditions andi
special studies to investigate specific
sources  and pollutants. About 3,00y
citizens  also perform volunteer envi-
ronmental monitoring in the Texas
Watch Program.

Surface Water Quality

    Of the 5,726 river miles sur-
veyed, 75% fully support aquatic life
uses, 20% partially support these
uses, and 5% are not supporting
aquatic life uses. The most common
pollutants impacting rivers and
streams are siltation and sediments,
total dissolved solids, nutrients, and
metals. Agricultural practices, such
as grazing and irrigation, elevate
nutrient and sediment loading into
streams. Point sources  also contrib-
ute to nutrient loads, while natural
conditions introduce metals and
sediments to streams in some areas.
Resource extraction and associated
activities, such as road construction,
also impact Utah's rivers and
streams.
    About 61% of the surveyed lake
acres fully support aquatic life uses,
32% partially support these uses,
and 7% do not support aquatic life
uses. The leading problems in lakes
include nutrients, siltation, low dis-
solved oxygen, suspended solids,
organic enrichment, noxious aquatic
plants, and violations of pH criteria.
The major sources of pollutants are
grazing and irrigation, industrial and
municipal point sources, drawdown
of reservoirs, and natural conditions.
    Fish and wildlife consumption
advisories are posted on the lower
portion of Ashley Creek drainage
and Stewart Lake in Uintah County
due to elevated levels of selenium
found in fish,  ducks, and American
coots.

Ground Water Quality

    In general, the quality of
ground water in Utah has remained
relatively good throughout the
State, although some ground water
degradation occurs in south central
Utah in the metropolitan area of
Salt Lake City and along the
Wasatch Front area from Payson
north to Brigham City. Sources of
ground water degradation include
irrigation, urbanization, landfills,
mining and mine tailings, and draw-
down. In 1994, new ground water
regulations went into effect.

    The State's Nonpoint Source
Task Force is responsible for coordi-
nating nonpoint source programs in
Utah. The Task Force is a broad-
based group with representatives
from Federal, State, and local agen-
cies; local governments; agricultural
groups; conservation organizations;
and wildlife advocates. The Task
Force helped State water quality
and agricultural agencies prioritize
watersheds in  need of NPS pollution
controls. As best management prac-
tices are implemented, the Task
Force will update and revise the
priority list.

Programs to Assess

    In 1993, Utah  adopted a
basinwide water quality monitoring
approach. Utah initiated basinwide
intensive studies in the Weber River
Basin in 1993  and  the Utah Lake-
Jordan River Basin in 1994. A fixed-
station network was also developed
to evaluate general, water quality
across the State. Utah's surface
water quality monitoring program
consists of about 200 ambient sta-
tions, 7 salinity monitoring stations,
and 30 biological monitoring sites.
In addition, 135 industrial and
municipal sites were monitored.

    Of the 5,264 miles of surveyed
rivers and streams, 81 % fully sup-
port aquatic life uses, 15% partially
support these uses, and 4%  do not
support aquatic life uses. Ten per-
cent of the surveyed rivers and
streams do not fully support swim-
ming. The most widespread  impacts
include siltation, thermal modifica-
tions, organic enrichment and  low
dissolved oxygen, nutrients,  patho-
gens, and other habitat alterations.
The principal sources of impacts are
agricultural runoff, streambank
destabilization and erosion, removal
of streamside vegetation, upstream
impoundments, flow regulation, and
land development.
    Sixty-four percent of the sur-
veyed lake acres (excluding Lake
Champlain) fully support aquatic life
uses, 27% partially support these
uses, and 9% do not support
aquatic life uses. The most common
problems in lakes include fluctuating
water levels, nutrient enrichment,
algal blooms, organic enrichment
and low dissolved oxygen, siltation,
and aquatic weeds. Eurasian
watermilfoil, an aquatic weed,,
infests  13% of the State's lakes that
are 20 acres or larger. Runoff from
agricultural  lands, roads,  and
streambank erosion are the most
frequently identified  sources of lake
problems.
    In  Lake Champlain, nutrients are
the major cause of impairment,
followed by fish consumption advi-

Ground  Water Quality

   The quality of Vermont's
ground waters is not well under-
stood due to a lack of resources
required to gather and assess
ground water data. Ground water
contamination has been detected at
hazardous waste sites. Other sources
of concern include failing septic
systems, old solid waste disposal
sites, agriculture, road salt, leaking
underground storage tanks, and
landfills. The State needs to imple-
ment a Comprehensive Ground
Water Protection Program, but lacks
the financial and technical resources
to do so.

    During the reporting period,
Vermont implemented dechlorina-
tion at 18 publicly owned sewage
treatment plants, which improved
water quality in about 47 miles of
rivers and streams. The State also
completed construction of the last
two planned sewage treatment
plants and upgraded four other
plants. To prevent habitat modifica-
tions, the State used the Section
401 water quality certification  pro-
cess to require minimum stream
flows at four hydroelectric facilities.
The stream flow requirements
should improve water quality on
11  miles of streams.

    Of the 34,575 river miles sur-
veyed, 90% fully support aquatic life
use, another 5% fully support this
use now but are threatened, and
5% do not fully support this use. As
in past years, fecal coliform bacteria
are the most widespread problem in
rivers and  streams. Agriculture and
pasture land contribute much of the
fecal coliform bacteria in Virginia's
waters. Urban runoff also is a signifi-
cant source of impacts in both rivers
and estuaries.
    Ninety-nine percent of Virginia's
publicly owned lakes fully support
their designated uses, and about
1 % do not fully support uses. The
most common problems in lakes
include dissolved oxygen depletion,
coliform bacteria, pH, and tempera-
ture, primarily from nonpoint
sources.
    In estuaries, 31 % of the sur-
veyed waters fully support aquatic
life use,  64% support this use but
are threatened,  and 5% partially
support this use. Nutrients are the
most common problem in Virginia's
estuarine waters, followed by or-
ganic enrichment and low dissolved
oxygen concentrations. All of
Virginia's Atlantic Ocean shoreline
fully  supports designated uses.
   Six advisories limit fish con-
sumption on 369 miles of Virginia's

Surface Water Quality

    The U.S. Virgin Islands consist
of three main islands (St. Croix, St.
Thomas, and St. John) and over 50
smaller islands and cays located in
the Caribbean Sea. The islands lack
perennial streams or large fresh-
water lakes or ponds. Water quality
in the U.S. Virgin Islands is generally
good but declining due to an
increase in point source discharges
and nonpoint source pollution
entering the marine  environment.
    The Virgin Islands municipal
sewage treatment plants, operated
by the Virgin Islands Department of
Public Works, are the .major source
of water quality violations in the
Territory. Neglect, combined with a
lack of qualified operators and
maintenance staff, results in fre-
quent breakdowns of lift stations,
pump stations, and pipelines.
Clogged and collapsed lines fre-
quently cause unpermitted dis-
charges into surface waters. Storm-
water also overwhelms sewage
treatment facilities and results  in
bypasses of raw or undertreated
sewage into bays and lagoons.
    Other water quality problems
result from  unpermitted discharges,
permit violations by private indus-
trial dischargers,  oil spills, and
unpermitted filling activities in man-
grove swamps. Nonpoint sources of
concern include failing septic sys-
tems, erosion from development,
urban runoff, waste disposal from
vessels, and spills.

Ground Water Quality

    The Virgin Islands' ground water
is contaminated with bacteria,  salt-
water, and volatile organic corn-
pounds. Septic tanks,  leaking
municipal sewer  lines, and sewage
bypasses contaminate ground water
with bacteria. Overpumping of aqui-
fers causes saltwater intrusion.  VOC
contamination is due to under-
ground storage tanks  and indis-
criminate discharges of waste oil.

    The Territorial Pollution Dis-
charge Elimination System (TPDES)
requires permits for all point source
discharges, but not all permitted
facilities are in compliance with their
permit requirements. During the

Division of Environmental Protection
brought four major violators into
compliance. The Virgin Islands is
also developing new regulations for

gram performs quarterly sampling
at 64 fixed stations around St.
Croix, 57 stations around St. Tho-

coliforms, turbidity, dissolved oxy-
gen, and temperature. Twenty sta-
tions  on St. Croix were also sampled
for phosphorus, nitrogen, and sus-
pended solids. Intensive studies,
which include biological sampling,
are conducted at selected sites that
may be affected by coastal develop-
ment. The Virgin Islands does not
monitor bacteria in shellfish waters
or toxics in fish, water, or sediment.

Surface Water Quality

    Washington reports that 18% of
their surveyed river miles fully sup-
port aquatic life uses, 22% partially
support these uses, and 60% do not
support aquatic life uses. In lakes,
35% of the surveyed acres fully
support aquatic life uses, and 65%
do not support aquatic life uses.
Thirty-two percent of the surveyed
estuarine waters fully support
aquatic life uses, 24% partially sup-
port these uses, and 44% do not
support aquatic life uses.
    Low levels of dissolved oxygen,
often naturally occurring, are the
major cause of impairment of desig-
nated uses in  estuaries. Bacterial
contamination, primarily from agri-
cultural runoff, onsite wastewater
disposal, and  municipal wastewater
treatment plants also causes  impair-
ment in estuaries.  Major causes of
impairment in lakes include nutri-
ents, pesticides, siltation, flow alter-
ation, and low dissolved oxygen.
Agricultural production is the pre-
dominant source of impairment in
lakes. Other sources include urban
runoff, land disposal, septic tanks,
and natural sources.  In rivers and
streams, agriculture is the major
source of water quality degradation,
followed by industrial point sources
and hydro-habitat modification.
Causes of water quality impairment
from these sources include thermal
modification, pathogen indicators,
and ammonia.

Ground Water Quality

   The highest priority ground
water issues in Washington are
nitrates, pesticides, and other agri-
cultural chemicals from fertilizer
applications, pesticide applications,
and septic tanks.

Surface Water Quality

    West Virginia reported that 42%
of their surveyed river and stream
miles have good water quality that
fully supports aquatic life uses, and
75% fully support swimming. In
lakes, 32% of the surveyed acres
have good water quality that fully
supports aquatic life uses and 100%
fully support swimming.
    Metals and siltation are the
most common water quality
problems in West Virginia's rivers
and lakes. Fecal coliforms and acid-
ity also impair a large number of
river miles. In lakes, oxygen-
depleting substances, acidity, nutri-
ents, and algal blooms also impair a
significant number of acres. Coal
mining impaired the most stream
miles, followed by municipal  point
sources and agriculture. Coal min-
ing was also the leading source of
degraded water quality in lakes,
followed by forestry and agriculture.
   West Virginia reported that fish
consumption  advisories are posted
for the Kanawha River, Pocatalico
River, Armour Creek, Ohio River,
Shenandoah River, North Branch of
the Potomac  River, the Potomac
River, and Flat Fork Creek. Five of
the advisories were issued because
of elevated dioxin concentrations in
bottom feeders. The other advisories
address PCBs  and chlordane in suck-
ers, carp, and channel catfish.

Ground Water Quality

   West Virginia ranked mining
and mine drainage as the highest
priority source of ground water
contamination in the State, followed
by municipal  landfills, surface water
impoundments (including oil  and
gas brine pits), abandoned hazard-
ous waste sites, and industrial land-
fills. West Virginia has documented
or suspects that ground water has
been contaminated by pesticides,
petroleum compounds,  other or-
ganic chemicals, bacteria, nitrates,
brine/salinity,  arsenic, and other
metals.

Surface Water Quality

    The Wisconsin Department of
Natural Resources (WDNR) found
that 78% of the surveyed river miles
fully support aquatic life uses, 2%
support these uses now but are
threatened, 14% partially support
aquatic life uses, and 6% do not
support aquatic life uses. WDNR
believes that the survey process
underestimated the number of
threatened river miles. The most
prevalent problems in rivers are
 habitat and flow alterations,
 siltation, excessive nutrients, and
 oxygen-depleting substances. The
 sources of these problems are often
 polluted runoff, especially in agricul-
 tural areas, and river modifications,
 such as ditching, straightening, and
 the  loss of wetlands alongside
 streams. Wastewater discharges also
 moderately impair more than 1,000
 miles of streams.
     About 57% of the surveyed  lake
 acres fully support aquatic life uses,
 3%  support these uses but are
 threatened, 15% partially support
 these uses, and 25% do not support
 aquatic life uses. The primary source
 of lake degradation is deposition of
 airborne pollutants, especially mer-
 cury, and polluted runoff. All of
 Wisconsin's Great Lakes' shoreline
 partially supports fish consumption
 use due to fish consumption adviso-
 ries posted throughout the Great
 Lakes. Bacteria from urban runoff
 also  impair swimming along 60
 miles of shoreline.

 Ground Water Quality

    The primary sources of ground
 water contamination  in Wisconsin
 are agricultural activities, municipal
 landfills, leaking underground stor-
 age tanks, abandoned hazardous
 waste sites, and spills. Other sources
 include septic tanks and land Eippli-
 cation of wastewater. Nitrate-
 nitrogen is the most common
 ground water contaminant. Nitrates
 come from fertilizers,  animal waste
 storage sites and feedlots, municipal
 and industrial wastewater and
sludge disposal, refuse disposal
areas, and leaking septic systems.

Programs to Restore
Water Quality

    WDNR is integrating multiple
agencies, programs, interests, and
jurisdictions in an "ecosystem
approach"  that looks at all parts of
the ecosystem when addressing
water quality—the land that drains
to the waterbody, the air above it,
the plants,  animals, and people
using it. Since the 1970s, WDNR
has prepared water quality manage-
ment plans for each of the State's
river basins that summarize the
condition of waters in each basin,
identify improvements and needs,
and make recommendations for
cleanup or protection. WDNR up-
dates the plans every 5 years and
uses the plans to rank watersheds
for priority projects under the Wis-
consin Nonpoint Source Water Pol-
lution Abatement Program and to
address wastewater discharge con-
cerns.

Programs to Assess
Water Quality

    In 1992, Wisconsin imple-
mented a surface water monitoring
strategy to support river basin  plan-
ning. The strategy integrates moni-
toring and management activities in
each of the State's river basins on
the 5-year basin planning schedule.
In recent years, Wisconsin has
placed more emphasis on monitor-
ing polluted  runoff and toxic sub-
stances in  bottom sediments and
tissues of fish and wildlife.

    Of the 6,091 river miles sur-
veyed, 13% fully support aquatic life
uses, 22% fully support these uses
now but are threatened, 63% par-
tially support aquatic life uses, and
2% do not support aquatic life uses.
The most widespread problems in
rivers and  streams are siltation and
sediment,  nutrients, total dissolved
solids and  salinity, flow alterations,
and habitat alterations. The most
prevalent sources of water quality
problems in rivers and streams are
rangeland, natural sources, irrigated
cropland, pasture land, and con-
struction of highways, roads, and
bridges.
    In lakes, 31% of the surveyed
acres fully support aquatic life uses,
47%  partially support these uses,
and 22% do not support aquatic life
uses.  The leading problems in lakes
are low dissolved oxygen concentra-
tions  and organic enrichment, nutri-
ents,  sediment and siltation, other
inorganic substances, and metals.
The most prevalent sources of water
quality problems in lakes are natural
sources, rangeland, irrigated crop-
land,  flow regulation, and municipal
sewage treatment plants.
    The State's water quality survey
is designed to identify water quality
problems, so it is reasonable to
assume that most of the  unassessed
waters are not impacted. However,
the State lacks definitive information
to that effect.

Ground Water Quality

    Some aquifers in Wyoming have
naturally high levels of fluoride,
selenium, and radionuclides. Petro-
leum  products and nitrates are the
most  common pollutants in Wyo-
ming's ground water, and leaking
underground storage tanks are; the
most  numerous source of contami-
nation. Other sources include
uranium and trona mineral mining,
agricultural activities, mill tailings,
spills,  landfills, commercial and
industrial sumps, septic tank
leachfields, wastewater disposal
ponds at coal-fired power plants
and other industrial sites, and com-
mercial oilfield disposal pits.

Programs to Restore
Water Quality

    Wyoming requires discharger
permits and construction permits for
all wastewater treatment facilities.
The Department of Environmental
Quality (DEQ) reviews proposed
plans and specifications to ensure
that plants  meet minimum design
criteria. Wyoming's nonpoint source
program is  a nonregulatory pro-
gram that promotes better manage-
ment practices for all land use activi-
ties, including grazing, timber har-
vesting, and hydrologic modifica-
tions.

Programs to Assess
Water Quality

    Wyoming is currently monitor-
ing reference stream sites around
the State in order to define charac-
teristics of relatively undisturbed
streams in each ecoregion. The
State is sampling chemical and bio-
logical parameters, such as dissolved
oxygen, nutrients, aquatic insect
species composition, species abun-
dance, and habitat conditions at the
candidate reference stream sites.
Once established, the reference  site
conditions will serve as the basis for
assessing other streams in the same
ecoregion or subecoregion.
Wyoming will use the reference
conditions to establish a volunteer-
biological monitoring program.

Tribal  Summaries
    This chapter provides individual
summaries of the water quality sur-
vey data reported by six American
Indian Tribes in their 1994 Section
305(b) reports. Tribal participation
in the Section 305(b) process grew
from two Tribes in 1992 to six
Tribes during the 1994 reporting
cycle, but Tribal water quality re-
mains unrepresented in this report
for the hundreds of other Tribes
established throughout the country.
Many of the other Tribes are in the
process of developing water quality
programs and standards but have
not yet submitted a Section 305(b)
report. As Tribal water quality
programs become established, EPA
expects Tribal participation in the
Section 305(b) process to increase
rapidly. To encourage Tribal partici-
pation, EPA has sponsored water
quality monitoring and assessment
training sessions at Tribal locations,
prepared streamlined 305(b) report-
ing guidelines for Tribes that wish
to participate in the process, and
published a brochure, Knowing Our
Waters: Tribal Reporting Under Sec-
tion 305(b). EPA hopes that subse-
quent reports to Congress will con-
tain more information about water
quality on Tribal lands.

Surface Water Quality

    The Campo Indian Reservation
covers 24.2 square miles in south-
eastern San Diego County, Califor-
nia. The Campo Indian Reservation
has 31  miles of intermittent streams,
80 acres of freshwater wetlands, and
10 lakes with a combined  surface
area of 3.5 acres.
    The natural water quality of
Tribal streams, lakes, and wetlands
ranges from good to excellent.
There are  no point source  discharges
 within or upstream of the Reserva-
 tion, but grazing livestock have
 degraded streams, lakes, and
 wetlands with manure containing
 fecal coliform bacteria, nutrients,
 and organic wastes. Livestock also
 trample streambeds and riparian
 habitats. Septic tanks and construc-
 tion also threaten water quality.

 Ground Water Quality

    Ground water supplies 100%
 of the domestic water consumed on
 the Campo Indian Reservation.
 Nitrate and bacteria from nonpoint
 sources occasionally exceed drinking
 water standards in some domestic
 wells. The proximity of individual
 septic systems to drinking water
 wells poses a human health risk
 because Reservation  soils do  not
 have good purification properties.
 Elevated iron and manganese levels
 may be due to natural weathering
 of geologic materials.

 Programs to Restore
 Water Quality

    The Campo Environmental Pro-
 tection Agency (CEPA) has authority

banks, construct sediment retention
structures, and fence streams and
riparian zones to exclude livestock.
CEPA will promulgate water quality
standards in 1995 that will establish
beneficial uses, water quality criteria,
and antidegradation  provisions for
all Tribal waters.
    In 1994,  the General Council
passed a resolution to suspend
cattle grazing on the Reservation for
at least 2 years and to concurrently
restore degraded recreational water
resources by  creating fishing and
swimming ponds for Tribal use.

Programs to Assess
Water Quality

    Streams,  wetlands, and lakes on
Tribal lands were not monitored
until CEPA initiated its Water
Pollution Control Program in 1992.
Following EPA approval of CEPA's
Quality Assurance Project Plan in
May 1993, CEPA conducted short-
term  intensive surveys to meet the
information needs  of the 305(b)
assessment process. Based on the
results of the 1994 305(b) assess-
ment, CEPA will develop a long-
term  surface  water monitoring pro-
gram for implementation in 1995.
CEPA will consider including biologi-
cal monitoring, physical and chemi-
cal monitoring, monthly bacterial
monitoring in lakes, toxicity testing,
and fish tissue monitoring in its
monitoring program.

           Surface Water Quality

              The Coyote Valley Band of the
           Pomo Indians is a federally recog-
           nized Indian Tribe, living on a
           57-acre parcel of land in Mendocino
           County, California. Segments of the
           Russian River and  Forsythe Creek
           flow past the Reservation, although
           flow diminishes in the summer and
           fall. Fishing, recreation, and religion
           are important uses for surface waters
           within the Reservation.
    Currently, the Tribe is con-
cerned about bacteria contamina-
tion in the Russian River,  potential
contamination of Forsythe Creek
from a malfunctioning septic system
leachfield, and habitat modifications
in both streams that impact aquatic
life. Past gravel mining operations
removed gravel spawning beds,
altered flow, and  created  very steep
banks. In the past, upstream  mining
also elevated turbidity in  Forsythe
Creek. The Tribe is also concerned
about a potential trend of increasing
pH values and high water tempera-
tures in Forsythe Creek during the
summer.

Ground  Water Quality

    The Coyote Valley Reservation
contains three known wells, but
only two wells are operable, and
only one well is in use. The old
shallow irrigation  well (Well A) was
abandoned  because it went dry
after the gravel mining operation on
Forsythe Creek lowered the water
table.  Well B, located adjacent to
Forsythe Creek, is used to irrigate a
walnut orchard. Well C, located on
a ridge next to the Reservation's
housing units, is not in use due to
severe iron and taste problems.
Sampling also detected high  levels
of barium, total dissolved  solids,
manganese, and conductivity in
Wells B and C. However,  samples
from Well B did not contain organic
chemicals, pesticides, or nitrate in
detectable amounts. Human waste

contamination from septic systems
may pose the greatest threat to
ground water quality.

Programs to Restore
Water Quality

    Codes and ordinances for the
Reservation will be established to
create a Water Quality and Manage-
ment Program for the Reservation.
With codes in place, the Coyote
Valley Tribal Council will gain the
authority to restrain the discharge of
pollutants that could endanger the
Reservation water supply and affect
the health and welfare of its  people,
as well as people in the adjacent
communities.

Programs to Assess
Water Quality

    The Tribal Water Quality
Manager will design a monitoring
system with assistance from environ-
mental consultants. The Water Qual-
ity Manager will sample a tempo-
rary monitoring station on Forsythe
Creek and a proposed sampling
station on the Russian River every
month. A fisheries biologist will
survey habitat on the rivers every
other year, as funding permits.

Surface Water Quality

    The Gila River Indian Commu-
nity occupies 580 square miles in
Central Arizona adjacent to the
metropolitan Phoenix area. About
8,500 members of the Pima and
Maricopa Tribes live in 22 small
villages inside the Community. The
Gila River is the major surface water
feature in the Community, but its
flow is interrupted by upstream
diversions outside of the Commu-
nity. Arid conditions and little
vegetative cover cause sudden runoff
with high suspended sediment
loads.
    Surface water was evaluated
with qualitative information due to
the lack of monitoring data. Most of
the Community's surface waters
have fair water quality that partially
supports designated uses because of
turbidity, siltation, salinity, and
metals loading from rangeland,
agriculture,  irrigation return flows,
and upstream mining. Information
was not available for assessing
effects of toxic contaminants  and
acid rain. There is no information
about water quality conditions in
wetlands.

Ground  Water Quality

    Community ground water qual-
ity generally complies with EPA's
Maximum Contaminant Levels, but
concentrations of total dissolved
solids often  exceed recommended
concentrations. However, members
of the Community have either
adjusted to  the aesthetic problem of
high dissolved solids or begun pur-
chasing bottled water, as have other
ground water users in the metro-
politan Phoenix area. Occasionally,
concentrations of coliform bacteria,
nitrates, and fluoride exceed recom-
mended criteria in  isolated wells.
Pathogens from onsite sewage dis-

Programs to Restore
Water Quality

    The Gila River Indian Commu-
nity needs a comprehensive water-
quality protection program, espe-
cially as nearby urban growth and
agricultural expansion create addi-
tional pollution and place new
demands on aquatic resources.  As a
first step, the Community's Water
Quality Planning  Office  intends to
address point sources of pollution
through a Ground Water Protection
Strategy. The Strategy will seek to
eliminate all discharges  that could
reach ground water or require rapid
mitigation if a discharge cannot be
avoided. Principles of Arizona's
Aquifer Protection Permit Program
may serve as a basis for the
Community's Strategy,  but the
Strategy will be streamlined and
simple to implement. The Strategy
may include technology-based or
standards-based protocols for facili-
ties and conditions for land  use
permits.

Programs to Assess
Water Quality

    The Community needs monitor-
ing programs for ground water,
surface water, and wetlands in order
to assess use support and to
support a water pollution control
program.

Surface Water Quality

    The Hoopa Valley Indian Reser-
vation covers almost 139 square
miles in Humboldt County in north-
ern California. The Reservation con-
tains 133 miles of rivers and streams,
including a section of the Trinity
River, and 3,200 acres of wetlands.
The Reservation does not contain
any lakes.
    Surface waters on the Reserva-
tion appear to be free of toxic:
organic chemicals, but poor forest
management practices and mining
operations, both on and off the
Reservation, have caused significant
siltation that has destroyed gravel
spawning beds. Water diversions,
including the damming of the
Trinity River above the Reservation,
have also stressed the fishery by
lowering stream volume and flow
velocity. Low flows raise water
temperatures and reduce flushing of
accumulated silt in the gravel beds.
Upstream dams also stop gravel
from moving downstream to
replace excavated gravel. Elevated
fecal coliform concentrations also
impair drinking water use on the
Reservation.

Ground Water Quality

    Ground water sampling
revealed elevated  concentrations of
lead, cadmium, manganese, iron,
and fecal coliforms in some wells.
The Tribe is concerned about poten-
tial contamination of ground water
from leaking underground storage
tanks, septic system  leachfields, and
abandoned hazardous waste sites
with documented soil contamina-
tion. These sites contain dioxins,
herbicides, nitrates, PCBs, metals,
and other toxic organic chemicals.
The Tribe's environmental consult-
ants are designing a ground v/ater
sampling program to monitor
potential threats to ground water.

Programs to Restore
Water Quality

    In 1990, EPA approved the
Hoopa Valley Tribe's application for
treatment as a State under the
Section 106 Water Pollution Control
Program  of the Clean Water Act.
Following approval, the Tribe
received Section 106 funding to
conduct a Water Quality Planning
and Management Program on the
Reservation. The Tribal Water Qual-
ity Manager is developing water
quality criteria for the Reservation,
with the  help of environmental con-
sultants. The proposed criteria will
be reviewed by the Hoopa Valley
Planning  Department and the Tribal
Council.

Programs to Assess
Water Quality

    In June of 1992, the Tribal  Plan-
ning Office and its hired consultants
sampled  eight surface water sites
and six ground water sites. The
Tribe measured different pollutants
at each site, depending on the sur-
rounding land use activities, includ-
ing conventional pollutants,  toxic
organic pollutants, metals, and fecal
coliforms. The Tribe plans to estab-
lish fixed monitoring sites in the
near future, which will complement
ongoing  biological monitoring con-
ducted by the Hoopa Valley Fisher-
ies Department on the Trinity River.

Surface Water Quality

    The 2,439-square-mile Hopi
Reservation, located in northeastern
Arizona, is bounded on all sides by
the Navajo Reservation. Surface
water on the Hopi Reservation con-
sists primarily of intermittent or
ephemeral streams. Only limited
data regarding stream quality are
available. The limited  data indicate
that some stream reaches may be
deficient in oxygen, although this
conclusion has not been verified by
repeat monitoring.
    In addition to the intermittent
and ephemeral washes and streams,
surface water on the Hopi Reserva-
tion occurs as springs where ground
water discharges as seeps along
washes or through fractures and
joints within sandstone formations.
The Hopi Tribe assessed 18 springs
in 1992 and 1993. The assessment
revealed that several springs had
one or more exceedances of nitrate,
selenium, total coliform, or fecal
coliform. The primary potential
sources of surface water contamina-
tion on the Hopi Reservation include
mining activities outside of the Res-
ervation, livestock grazing, domestic
refuse, and wastewater lagoons.

Ground Water Quality

    In general, ground water quality
on the Hopi Reservation is good.
Ground water from the N-aquifer
provides drinking water of excellent
quality to most of the Hopi villages.
The D-aquifer, sandstones of the
Mesaverde Group, and alluvium also
provide ground water to shallow
stock and domestic wells, but the
quality of the water from these
sources is generally of poorer quality
than the water supplied by the
N-aquifer.
    Mining activities outside of the
Reservation are the most significant
threat to the N-aquifer. Extensive
pumping at the Peabody Coal Com-
pany Black Mesa mine may induce
leakage of poorer quality D-aquifer
water.into the N-aquifer. This
potential problem is being investi-
gated under an ongoing  monitoring
program conducted by the U.S.
Geological Survey. In addition, the
U.S. Department of Energy  is

from abandoned uranium tailings at
Tuba City. Other potential sources
of contamination in shallow wells
include domestic refuse, under-
ground storage tanks,  livestock graz-
ing, wastewater lagoons, and septic
tanks.

Programs to Restore
Water Quality

    Draft water quality standards
(including an antidegradation
policy) were prepared  for the Tribe
in 1993. The Tribe is also reviewing
a proposed general maintenance
program to control sewage  lagoons.
The Tribe has repeatedly applied for
EPA grants to investigate nonpoint
source pollution on the Reservation,
but the applications were denied.

Programs to Assess
Water Quality

    The Tribe focused on monitor-
ing springs and ground water dur-
ing the 1994 reporting cycle. Future
surface water monitoring will assess
aquatic life in springs,  lakes, and
streams; baseflow and storm flow in
streams; and biological, sediment,
and chemical content  of streams
and springs.

Surface Water Quality

   The Soboba Reservation encom-
passes about 9.2 square miles in
southern California about 80 miles
east of Los Angeles. The San Jacinto
River is the major surface water fea-
ture on the Reservation. At one time,
the San Jacinto River flowed year
round, but upstream diversions and
ground water withdrawals outside
of the Reservation have reduced the
flow to intermittent status for many
years.
    The chemical quality of surface
water on the Soboba Reservation is
excellent and remains unimpaired to
date, based on very limited data.
The quality of surface water, to the
extent it is available, fully supports
the existing uses of ground water
recharge, wildlife habitat, and recre-
ation. Overall, the greatest threat to
water quality on the Soboba Reser-
vation is the reduction of surface
flows and ground water storage by
off-Reservation diversions and
pumping.

Ground Water Quality

    Three major water supply wells
extract water from two aquifers on
the Soboba Reservation. Ground
water overdraft outside the Reserva-
tion has seriously reduced the with-
drawal capacity of the Reservation's
wells and aquifers. The chemical
quality of ground water on the
Soboba Reservation is excellent and
remains unimpaired to date. The
single most critical threat to water
quality is a proposal by the Eastern
Municipal Water District to routinely
recharge treated effluent at a site
within 600 feet of an existing
Soboba well.

    There are no formal water pol-
 lution control programs in place on
 the Reservation. However, the Band
 has achieved compliance with EPA
 monitoring and treatment require-
 ments for its domestic ground water
 supply system and the  Band is con-
 sidering development of a wellhead
 protection program. In addition, the
 Band is seeking assistance from EPA
 under the Indian Environmental
 General Assistance Program to edu-
 cate the Band about water quality
 issues, establish water resource pro-
 tection ordinances, and undertake
 other water protection  initiatives.
    The Soboba Band is continuing
 its struggle to assert and defend its
 water rights. The Soboba Band has
 started negotiating with the major
 water users outside of the Reserva-
 tion to fairly apportion the waters of
 the basin. Nondegradation of water
 quality will be a basic element of
 the Band's position in these negotia-
 tions.

    The Band advocates sharing  and
cooperative analysis of data on the
hydrology and water quality of the
San Jacinto watershed to facilitate
water rights  negotiations. This affir-
mative approach to water resource
management should lead to a sys-
tematic, integrated water quality
monitoring program for the basin
that will benefit all users.

Surface Water Quality

   The Delaware River Basin covers
portions of Delaware, New Jersey,
New York, and Pennsylvania. The
Delaware  River system consists of a
207-mile freshwater segment, an
85-mile tidal reach, and the  Dela-
ware Bay. Nearly 8 million people
reside in the Basin, which is  also the
home of numerous industrial
facilities and the port facilities of
Philadelphia, Camden, and
Wilmington.
   All of the riverine waters and
94% of the estuarine waters in the
Basin have good water quality that
fully supports aquatic life uses.
Three percent of the riverine waters
do not support fish consumption
and 2% have fair quality that par-
tially supports swimming. In estua-
rine waters, poor water quality im-
pairs shellfishing in 29% of the sur-
veyed waters. Low dissolved oxygen
concentrations and toxic contami-
nants in sediment degrade portions
of the lower tidal river and estuary.
Fecal coliform bacteria and high pH
values impair a few miles of the
Delaware River. As of April  1994,
fish consumption advisories were
posted on about 6 miles of the
Delaware River and 22 square miles
of the tidal river, cautioning the
public to restrict consumption of
channel catfish, white perch,  and
american eels contaminated with
PCBs and chlordane.
    In general,  water quality has
improved since the 1992 305(b)
assessment period. Tidal river oxy-
gen levels were higher during the
critical summer period, residues of
toxic chemicals in fish and shellfish
declined, and populations of impor-
tant fish species (such as striped
bass and American shad) increased
during the 1994 assessment period.

reduce point source discharges of
oxygen-depleting wastes and other
pollutants. These programs will
continue, in addition to new efforts
to determine the role of stormwater
runoff. The Commission also
adopted new Special Protection
Waters regulations to protect exist-
ing high water quality in the upper
reaches of the nontidal river from
the effects of future population
growth and development. The-
Commission also promotes a
comprehensive watershed manage-
ment approach to coordinate
several layers of governmental
regulatory programs impacting the
Delaware River Basin.

Programs to Assess
Water Quality

    The Commission conducts an
intensive monitoring program along
the entire length of the Delaware
River and Estuary. At least a dozen
parameters are sampled at most
stations, located about 7 miles
apart. The new Special Protection
Waters regulations  require even
more sophisticated monitoring and
modeling, such as biological moni-
toring and continuous water quality
monitoring. The Combined Sewer
Overflow Study and the Toxics
Study will both require additional
specialized water quality analyses in
order to understand how and why
water quality  is affected. New
management programs will very
likely require customized monitoring
programs.

Surface Water Quality

    Established in 1936 by Federal
mandate, the Interstate Sanitation
Commission (ISC) is a tristate envi-
ronmental agency of the States of
New Jersey, New York, and Con-
necticut. The Interstate Sanitation
District encompasses approximately
797 square miles of estuarine waters
in the Metropolitan Area shared  by
the States, including the Arthur Kill/
Kill Van Kull, Lower Hudson River,
Newark Bay, Raritan Bay, Sandy
Hook Bay, and Upper New York
Bay.
    In general, water quality in the
District waters improved during the
1992-1993 reporting cycle. Dis-
solved oxygen concentrations
increased and bacteria densities
decreased. The reduction in bacteria
is due to the Commission's year-
round disinfection regulations
(which took effect in 1986), and the
elimination of discharges receiving
only primary treatment at Middlesex
and Hudson Counties.
    Topics of concern to the ISC
include compliance with ISC regula-
tions, toxic contamination in District
waters, pollution from combined
sewer overflows,  closed shellfish
waters, and wastewater treatment
capacity to handle growing flows
from major building projects.

Ground Water Quality

    The ISC's primary focus is on
surface waters shared by the States
of New Jersey, New York, and Con-
necticut.

    The ISC actively participates in
the  Long Island Sound Study, the
New York-New Jersey Harbor Estu-

for the Port of New York and New
Jersey. The ISC has representatives

November 1993. Representatives of
State, county, and  municipal health
departments and environmental
agencies were invited to discuss
bathing beach monitoring and clo-
sure policies. The public and envi-
ronmental advocacy groups were
also invited. The ISC reported the
results to the HEP Pathogens Work
Group.
    During 1993, the ISC inspected
71 CSO outfalls in  an effort to iden-
tify and eliminate all dry weather
discharges. The ISC notified the
States of dry weather discharges
detected during field investigations
and worked with the States to elimi-
nate dry weather discharges.

Programs to Assess
Water Quality

    The ISC performs intensive
ambient water quality surveys and
samples effluent discharged by pub-
licly owned  and private wastewater
treatment facilities  and industrial
facilities into District waterways. By
agreement,  the ISC's effluent
requirements are incorporated into
the individual discharge permits
issued by the participating  States.

was established in 1948 by the
signing of the Ohio River Valley
Water Sanitation Compact by
Illinois, Indiana, Kentucky, New
York, Ohio, Pennsylvania, Virginia,
 and West Virginia. ORSANCO is an
 interstate agency with multiple
 responsibilities that include detect-
 ing interstate spills, developing
 waste treatment standards, and
 monitoring and assessing the Ohio
 River mainstem. The mainstern runs
 981 miles from Pittsburgh, Pennsyl-
 vania, to Cairo, Illinois.
    The most common problems in
 the Ohio River are PCB and chlor-
 dane contamination in fish and
 bacteria, pesticides, and metals in
 the water column. The States have
 issued fish consumption advisories
 along the entire length of the Ohio
 River based on ORSANCO data.
 ORSANCO also suspects that com-
 munity combined sewer overflows
 along the entire length of the river
 elevate bacteria levels and impair
 swimming. ORSANCO detected
 bacteria contamination at all seven
 monitoring stations downstream of
 major urban areas with a large
 number of CSOs.
    Copper, lead, and zinc
 exceeded criteria for protecting
 warm water aquatic life in waters
 near the Gallipolis-Huntington area,
 Cincinnati, Louisville, and the Padu-
 cah area. Acid mine drainage is a
 suspected source of some metals in
 the Ohio River.
    Public water supply use of the
 Ohio River is impaired by 1,2-
 dichloroethane near Paducah and
 by atrazine near Louisville and the
 mouth of the River at Grand Chain,
 Illinois. The extent of atrazine
 contamination is unknown because
few sites are monitored for atrazine.
NOTE- A more detailed account of water quality throughout the entire Ohio River Basin is presented in Chapter 12.

Ground Water Quality

    ORSANCO does not have juris-
diction over ground water in the
Ohio River Basin.

Programs to Restore
Water Quality

    In 1992, an interagency
workgroup developed a CSO
program for the Ohio River Basin
with general recommendations to
improve coordination of State CSO
strategies.  In 1993,  ORSANCO
added requirements for CSOs to the
Pollution Control Standards for the
Ohio River and the  Commissioners
adopted a strategy  for monitoring
CSO impacts on Ohio River quality.
The Commission also established a
Nonpoint Source Pollution Abate-
ment Task Force composed of
ORSANCO Commissioners, repre-
sentatives from State NPS control
agencies, and representatives from
industries that generate NPS pollu-
tion.

Programs to Assess
Water Quality

    ORSANCO operates several
monitoring programs on the Ohio
River mainstem and several major
tributaries, including fixed-station
chemical sampling, daily sampling
of volatile  organic chemicals at
water supply intakes, bacterial moni-
toring, fish tissue sampling, and fish
community monitoring. ORSANCO
uses the Modified Index of Well
Being (Mlwb) to assess fish commu-
nity characteristics,  such as total
biomass and species diversity.

Surface Water Qualify

    The Susquehanna River drains
27,510 square miles from parts of
New York, Pennsylvania, and Mary-
land, and delivers over half of the
fresh water entering the Chesapeake
Bay. The Susquehanna River Basin
Commission (SRBC) surveyed
17,464 miles of the 31,193 miles of
rivers and streams in the Susque-
hanna River Basin. Over 90% of the
surveyed river miles fully support
designated uses, 4% partially
support uses, and 6% do not sup-
port one or more designated uses.
Metals, low pH, and nutrients are
the primary causes of stream
impacts in the Basin. Coal mine
drainage is the source of most of
the metals and pH problems
degrading streams. Sources of nutri-
ents include municipal and domes-
tic wastewater discharges, agricul-
tural runoff, and ground water
inflow from  agricultural areas.
    During past reporting cycles,
SRBC did not conduct any lake or
reservoir assessments. However, a
2-year project funded by EPA and
Pennsylvania should provide a foun-
dation of lake data upon which
SRBC can launch its lake assessment
program.

Ground Water Quality

    Ground water in the Basin is
generally of adequate quality for
most uses. Many of the ground
water quality problems in the Basin
are related to naturally dissolved
constituents (such as iron, sulfate,
and dissolved solids) from  the geo-
logic unit from which the water
originates. The SRBC is concerned
about ground water contamination
from septic systems and agricultural
activities.

Programs to Restore
Water Quality

    The Susquehanna River Basin
Compact assigns primary responsi-
bility for water quality management
and control to the signatory States.

The SRBC's role is to provide a
regional perspective for coordinating
local,  State, and Federal water
quality management efforts. For
example, the SRBC reviews pro-
posed discharge permits (issued by
the States) and evaluates potential
interstate and regional impacts. The
SRBC also recommends modifica-
tions to State water quality stan-
dards to improve consistency
among the States.

Programs to Assess
Water Quality

    The SRBC's role in interstate
and regional issues shaped the
Commission's monitoring program.
The SRBC's fixed-station monitoring
network collects base flow data and
seasonal-storm nutrient data on the
Susquehanna mainstem and major
tributaries to assist the Chesapeake
Bay Program in evaluating nutrient
reduction projects. The SRBC also
established an interstate stream
water quality network to evaluate
streams crossing State boundaries
for compliance with State water
quality standards. Biological moni-
toring is conducted annually  at 29
sites. The SRBC also conducts inten-
sive subregional surveys to analyze
regional water quality and biological
conditions.

The Watershed  Protection
Approach  and  Place-based
Management  Programs
Watershed
Protection
Approach
Introduction
   The Nation's aquatic resources
are among its most valuable assets.
Although significant strides have
been made in reducing the impacts
of discrete pollutant sources, our
aquatic resources remain at risk
from a combination of point sources
and complex nonpoint sources,
including air pollution. Since 1991,
the EPA has promoted the water-
shed protection approach as a holis-
tic framework for addressing com-
plex pollution problems.
   The watershed protection
approach is a  place-based strategy
that integrates water quality man-
agement activities within hydrologi-
cally defined drainage basins-
watersheds-rather than areas
defined by political boundaries.
Thus, for a given watershed, the
approach encompasses not only the
water resource (such as a stream,
lake, estuary, or ground water aqui-
fer), but all the land from which
water drains to the resource
(Figure 12-1). To protect water
resources, it is increasingly impor-
tant to address the condition of,
land areas within the watershed
because water carries  the effects of
human activities throughout the
watershed as it drains off the land
into surface waters or leaches into
the ground water.

                            River
The watershed protection approach may be applied to watersheds of all sizes. Watershed size
varies, depending on the objectives and scope of a watershed initiative. For example, part-
nerships are developing comprehensive management strategies for the entire Great Lakes
Basin, the watershed draining into each Great Lake, and the watersheds draining into indi-
vidual areas of concern on the Great Lakes, such as the Kalamazoo River watershed. Each
level of detail provides additional insight about the factors contributing to complex water
quality problems.

302  Chapter Twelve The Watershed Protection Approach and Place-based Management Programs
                                         Several key principles guide the
                                     watershed protection approach:

                                     •  Place-based focus - Resource
                                     management activities are directed
                                     within specific geographical areas,
                                     usually defined by watershed boun-
                                     daries, areas overlying or recharging
                                     ground water, or a combination of
                                     both.

                                     •  Stakeholder involvement and
                                     partnerships - Watershed initiatives
                                     involve the people most likely to be
                                     affected by management decisions
                                     in  the decision making process.
                                     Stakeholder participation ensures
                                     that the objectives of the watershed
                                     initiative will include economic
                                     stability and that the people who
                                     depend on the water resources in
                                     the watershed will participate in
                                     planning  and implementation activi-
                                     ties. Watershed initiatives also estab-
                                     lish partnerships between Federal,
                                     State, and local agencies and non-
                                     governmental organizations with
                                     interests in the watershed.

                                     •  Environmental objectives - The
                                     stakeholders and partners identify
                                     environmental objectives (such as
                                     "populations of striped bass will
                                     stabilize or increase") rather than
                                     programmatic objectives (such  as
                                     "the State will eliminate the backlog
                                     of  discharge permit renewals")  to
                                     measure success of the watershed
                                     initiative. The  environmental objec-
                                     tives are based on the condition of
                                     the ecological resource and the
                                     needs of people in the watershed.

                                     •  Problem identification  and
                                     prioritization - The stakeholders
                                     and partners use sound scientific
                                     data and methods to identify and
                                     prioritize the primary threats to
 human and ecosystem health within
 the watershed. Consistent with the
 Agency's mission, EPA views ecosys-
 tems as the interactions of complex
 communities that include people;
 thus, healthy ecosystems provide for
 the health  and welfare of humans as
 well as other living things.

 • Integrated actions - The stake-
 holders and partners take corrective
 actions in a comprehensive arid
 integrated  manner, evaluate success,
 and refine  actions if necessary. The
 watershed  protection approach
 coordinates activities conducted by
 numerous  government agencies and
 nongovernmental organizations to
 maximize efficient use of limited
 resources.

    EPA's Office of Water envisions
 the watershed protection approach
 as the primary mechanism for
 achieving clean water and healthy,
 sustainable ecosystems throughout
 the Nation. The watershed protec-
 tion approach enables stakeholders
 to take a comprehensive  look at
 ecosystem  issues and tailor correc-
 tive actions to local concerns within
 the coordinated framework of a
 national water program. The
 emphasis on public participation
 also provides an opportunity to
 incorporate environmental justice
 issues into  watershed restoration
 and protection solutions.
    In May of 1994, the EPA Assis-
 tant Administrator for Water, Robert
 Perciasepe, created the Watershed
 Management Policy Committee to
 coordinate  the EPA water program's
 support of  the watershed protection
 approach. During 1995, EPA's water
 program managers, under the direc-
tion of the  Watershed Policy Com-
 mittee, evaluated their programs

-------
                        Chapter Twelve The Watershed Protection Approach and Place-based Management Programs   303
and identified additional activities
needed to support the watershed
protection approach in  an action
plan. The action plans address
several broad directions:

•  Enhance interagency coordina-
tion at the Federal, State, and local
levels.

•  Build State, Tribal, and Territorial
watershed protection capabilities by
encouraging States and Tribes to
integrate existing  programs (such as
NPDES Permitting Programs, Section
319 Nonpoint Source Programs,
Comprehensive State Ground Water
Protection Programs, and State Wet-
lands Conservation Plans) using
comprehensive State, Tribal, and
Territorial watershed approaches.

•  Develop tools (such as methods,
models, criteria, indicators, data
management, and monitoring tech-
niques) for implementing the water-
shed protection approach.

•  Provide training on watershed
approach concepts and tools.

•  Improve coordination within  EPA,
and streamline program require-
ments (such as allowing multipur-
pose planning, funding, and report-
ing for watershed efforts).

•  Reach out to watershed stake-
holders by publicizing accomplish-
ments at meetings and conferences
and in newsletters and publications.

    EPA's Office of Water will con-
tinue to promote and support the
watershed protection approach. This
approach relies on active participa-
tion by local governments and
citizens who have the most direct
knowledge of local problems and
opportunities in their watersheds.
However, the Office of Water will
look to the States, Tribes, and Terri-
tories to create the framework for
supporting local efforts because
most EPA programs are imple-
mented by the States, Tribes, and
Territories.
    EPA's Office of Water has
already taken steps to reorient and
coordinate its programs to support
the comprehensive watershed pro-
tection approach (see the highlight
on the NPDES Watershed Strategy).
In addition, EPA is supporting water-
shed management projects across
the Nation that coordinate numer-
ous agencies to simultaneously
achieve multiple objectives. These
projects are implemented by the
States with EPA support channeled
through various Office of Water
programs, including the Section 319
Nonpoint Source Program, the
Section 320 National Estuary Pro-
gram, the Wetlands Grant Program,
and the Comprehensive State
Ground Water Protection Program
(see highlight on the Bear River
Project).
    The Office of Water will  con-
tinue to build upon its experience
with established place-based pro-
grams, such as the Chesapeake Bay
Program and the Great Lakes
National Program, to eliminate bar-
riers to the watershed protection
approach. These integrated pro-
grams (described  later in this chap-
ter) laid the foundation for the
Agency's shift toward comprehen-
sive watershed management and
continue to provide models  for
implementing the  "place-based
approach" to environmental
problem solving.

                                   Watershed Strategy
                  On March 21, 1994, EPA issued
               the NPDES Watershed Strategy to
               fully integrate the NPDES permit
               program into the watershed protec-
               tion approach. Over the past 20
               years, the NPDES program has
               employed permitting requirements
               to achieve significant reductions in
               pollutant discharges to surface
               waters from industrial and municipal
               facilities (see  Chapter 10 for a full
               description of the Point Source Con-
               trol Program). In most cases, the
               States have assumed responsibility
               for implementing the NPDES permit
               program. In recent years, the NPDES
               program expanded to address
               remaining sources of pollutant dis-
               charges, including combined sewer
               overflows and storm water dis-
               charges. The  NPDES Watershed
               Strategy provides a  cost-effective
               mechanism for addressing the
               remaining point sources  of environ-
               mental impacts while maintaining
               successful control of traditional
               discharges.
                  The NPDES Strategy outlines
               national objectives and implementa-
               tion activities  to (1) integrate NPDES
               program functions into the broader
               watershed protection approach,
               and (2) support development of
               statewide watershed or basin
               approaches. The  Strategy identifies
 six essential items that EPA
 Headquarters and the Regions must
 support:

 •  Statewide coordination -
 promote development of watershed
 or basin management frameworks
 that identify the roles and responsi-
 bilities of participating programs,
 long-term programmatic and envi-
 ronmental goals, geographically
 delineated basins, and a schedule
 for periodically evaluating the envi-
 ronmental conditions in each basin.

 •  NPDES permits - encourage
 States to develop basin  manage-
 ment plans that synchronize permit
 issuance within basins.

 •  Monitoring and assessment -
 encourage the States to develop
 statewide monitoring strategies that
 coordinate collection and analysis of
 data with NPDES permit issuance
 and other management activities
 within basins.

 •  Programmatic measures and
 environmental indicators - revise
 national accountability measures to
facilitate implementation of water-
shed protection activities and
establish new measures of success
that reflect progress toward
                                                                             	   "-"•• ' • •'-'

achieving watershed protection
goals.

• Public participation - promote
long-term public support for basin
management activities by providing
opportunities for the public to
participate in goal development,
priority setting, strategy develop-
ment, and implementation.

• Enforcement - coordinate com-
pliance and enforcement programs
and activities at the Federal, State,
Territorial, and Tribal levels to focus
resources on priority point sources
within identified basins.

The NPDES Watershed Strategy
is intended to support ongoing
State and Tribal initiatives and
supplement the efforts of other
environmental programs by identify-
ing areas where the NPDES pro-
gram can contribute. The Strategy
recognizes that the NPDES program
may play a central role in a number
of watersheds, but point sources will
not represent the primary stressors
in many watersheds. In such cases,
the NPDES program can support
and facilitate activities for meeting
environmental objectives, such as
monitoring and public participation.

.




Several State and EPA Regions
have taken significant steps toward
integrating NPDES program activi-
ties into the broader watershed
protection approach, but the
NPDES Watershed Strategy remains
largely untapped. To promote
implementation at the national
level, each EPA Regional Office
completed the following action
items during FY95:

• Regional State-by-State Assess-
ments and Action Plans - assess
current -watershed protection activi-
ties in each State and develop
Regional action plans that identify
how the Region will support and
facilitate each State's movement
toward the watershed protection
approach.

• State/EPA Workplan Agreements
- include specific activities within
workplans that will promote the
central components of the NPDES
Watershed Strategy.

• Internal Coordination - develop
Regional strategies that describe the
Regional decision making processes,
oversight role, and internal coordi-
nation efforts necessary to ensure
support for the watershed protec-
tion approach.

                                    Implementing the Watershed
                                    Protection Approach  on the
                                    Bear River,  Utah
                                      The Bear River has a 7,600-
                                   square mile watershed located in
                                   Wyoming, Utah, and Idaho. The
                                   Utah Division of Water Resources
                                   initiated the project in an effort to
                                   resolve major environmental prob-
                                   lems:

                                   • Soil erosion, increased sediment
                                     loadings, coliforms, and high
                                     nutrient loadings due to animal
                                     feeding operations, dairies, urban
                                     development, roads, oil and gas
                                     exploration,  and silviculture

                                   • Riparian vegetation removal

                                   • Stream channelization

                                   • Degraded stream channels and
                                     streambanks.

                                      Interest in increasing the use of
                                   the river as a drinking water source
                                   for the growing urban population in
                                   the lower basin and along the
                                   Wasatch Front prompted the Utah
                                   Legislature to enact the Bear River
                                   Development Act and fund a Bear
                                   River water development and  man-
                                   agement plan. The effort is to
                                   address both water development
                                   and water quality issues, with  a
                                   water quality plan that includes a
 broad-reaching analysis of pollutant
 loading to the river as well as
 chemical, biological, and physical
 habitat assessments. Because the
 Bear River encompasses Utah,
 Wyoming, and Idaho, a regional
 planning effort has been initiated.
 The purpose of the regional effort is
 to share information, coordinate
 planning efforts, and involve
 "grassroots" direction and participa-
 tion. An array of water projects  in
 the Bear River  Basin initiated by
 different organizations and groups
 are being coordinated through the
 Bear River Watershed Water Quality
 Coordination Committee.
    For example, the State of Utah,
 EPA, and the U.S. Department of
Agriculture (USDA) initiated  a
watershed restoration project on the
 Little Bear River (one of the major
tributaries in the basin) using funds
from USDA and EPA. The project
includes stream channel and ripar-
ian habitat restoration, land  man-
agement,  and animal waste treat-
ment actions. Several additional
nonpoint source projects are now
under way in Wyoming that are
aimed at restoring tributary streams
that have  been impacted by
channelization, streambank modifi-
cation, and riparian habitat loss.
                                                                                  iMiiijiiiiijSJi

                                    Management

                                    Programs

                                    Introduction

                                       The programs described in this
                                   section (the Great Waterbodies
                                    Program, the Great Waters Program,
                                   and the National Estuary Program)
                                   embody a watershed protection
                                   approach at different scales. The
                                   Great Waterbodies Program and the
                                   Great Waters Program target entire
                                   drainage basins, such as the Gulf of
                                   Mexico, which drains two-thirds of
                                   the continental United States and a
                                   large portion of Mexico. The
                                   National Estuary Program (NEP)
                                   targets clusters of watersheds that
                                   drain into a specific estuary, such as
                                   Galveston Bay. NEP sites may be
                                   nested within a larger basin
                                   targeted by the Great Waterbodies
                                   or Great Waters Programs, such as
                                   the Gulf of Mexico.
                                       Although scales differ, these
                                   programs share a common place-
                                   based ecosystem approach to solv-
                                   ing water quality problems. The
                                   ecosystem approach recognizes that
                                   all components of  the environment
                                   are interconnected and that pollu-
                                   tion released in one area can cause
                                   problems in another. This concept
                                   requires all responsible parties to
                                   recognize and reduce impacts.
                                   Therefore, managing pollution on
                                   the ecosystem level requires build-
                                   ing institutional frameworks that
                                   involve all affected parties, such as
                                   agricultural interests, environmental
                                   advocacy organizations, industry,
                                   government agencies, and private
                                   citizens. Consensus is a  key to
managing pollution on the ecosys-
tem level.
    The ecosystem approach also
encourages pollution prevention
and efforts to avoid actions that can
even indirectly lead to contamina-
tion of the waterbody. Although
such ecosystem perspectives are
hardly new, they are more often
applied to much  smaller unit; such
as watersheds.

The Great
Waterbodies Program


Background

    The Great Waterbodies Program
manages water quality protection
in the three largest watersheds tar-
geted by EPA: the Gulf of Mexico,
the Great Lakes, and the Chesa-
peake Bay.

The Gulf of Mexico

Background

    The Gulf of Mexico is fed by
rivers draining a vast area in five
countries. The Gulf's watershed,
which covers almost 2 million
square miles, is far larger than any
other in the Nation. It includes two-
thirds of the continental United
States,  one-half of Mexico, and
parts of Canada, Guatemala, and
Cuba. Over 1.1 million square miles
of the Gulf's watershed are in the
Mississippi River drainage system,
making the Mississippi the single
largest freshwater riverine influence
on the Gulf.
    The Gulf of Mexico is enor-
mously productive and diverse.
Covering 600,000 square miles, the
Gulf provides habitat for a mcijority

                         Chapter Twelve  The Watershed Protection Approach and Place-based Management Programs   309
of U.S. migratory waterfowl. Its
commercial fisheries produced 1.7
billion pounds of fish, oysters,
shrimp, and crabs in 1993, and
almost 90% of U.S. offshore oil and
gas comes from  Gulf waters. Seven
of our Nation's busiest ports border
its shores, and many nations of the
world fish its waters. As a recre-
ational resource, the Gulf and adja-
cent estuaries provide a playground
for sport fishing, diving, water ski-
ing, sailing, swimming, sunbathing,
beachcombing, or just plain relax-
ing.
    However, the health and vitality
of the Gulf have been declining in
recent years, caused in part by
increasing populations along its
coast and upstream tributaries in
the watershed and the growing
demand upon its resources and in
part by the accumulation of years of
careless depletion, abuse, and ne-
glect of its environment. These
problems in the Gulf have reduced
its ability to regenerate naturally.
The result has been alarming dam-
age and destruction of the Gulfs
ecosystem and habitats, particularly
wetlands and seagrasses. An esti-
mated 50 square miles of Gulf wet-
lands were lost each year between
the mid-1950s and the 1970s.
These losses stem from: marine
debris, toxic substances and pesti-
cides, coastal and shoreline erosion,
nutrient enrichment, alterations in
freshwater inflow,  nonpoint source
runoff, and contaminants from inef-
ficient or nonexistent septic systems.
The effects are seen in decreasing
populations of waterfowl and
marine wildlife, increasing degrada-
tion and loss of  wetlands and  other
habitat, and growing threats to
human health from environmental
pollution.
    In response to signs of serious
long-term environmental damage
throughout the Gulfs coastal and
marine ecosystem, the Gulf of
Mexico  Program (CMP) was estab-
lished in August 1988 with EPA as
the lead Federal agency. The Pro-
gram Office is located at Stennis
Space Center in Mississippi. Its main
purpose is to develop and help
implement a strategy to protect,
restore,  and maintain the health
and productivity of the Gulf. The
CMP is  a grass roots program that
serves as a catalyst to promote shar-
ing of information, pooling of
resources, and coordination of
efforts to restore and reclaim wet-
lands and wildlife habitat, clean up
existing pollution,  and prevent
future contamination and destruc-
tion of Gulf resources.
    Because of the immense geo-
graphical expanse of the Gulf, as
well as the numerous, and diverse
nature of, environmental threats to
it, no one agency has the expertise
and authority needed to deal effec-
tively with the vast array of prob-
lems that threaten the Gulf. In
response to this, the CMP office at
Stennis  Space Center has evolved
into a multiagency organization
with staff from the Natural
Resources Conservation  Service,
National Oceanic and Atmospheric
Administration/National Marine
Fisheries Service, Fish and Wildlife
Service, Food  and Drug Administra-
tion, National Aeronautics and
Space Administration, Mississippi
Cooperative Extension Service, and
Mississippi Soil and Water Conserva-
tion Districts. This multi-agency staff
assists in directing the organizational
and operational strategy of the pro-
gram on a day-to-day basis to more
effectively deal with  Gulf issues. In

-------
310  Chapter Twelve The Watershed Protection Approach and Place-based Management Programs
  77/e goals of the Gulf of
  Mexico Program are to

  • Protect, restore^ and
    enhance the coastal and
    marine waters of the Gulf
    and its natural coastal
    habitats

  • Sustain living resources

  • Protect human health and
    tfie food supply
  • Ensure recreational use of
    Gulf shores, beaches, and
    waters in ways consistent
    with the economic well-
    being of the region.
 addition, advantages of this staff
 include a broad-based in-house
 expertise and a far-reaching net-
 working capability.
    The CMP mobilizes Federal,
 State, and local government; busi-
 ness and industry; academia; and
 the community at large through
 programs of public awareness, infor-
 mation dissemination, forum discus-
 sions, citizen committees, and tech-
 nology application. A Policy Review
 Board and the Management Com-
 mittee determine the scope and
 focus of GMP activities. The pro-
 gram also receives input from a
 Technical Advisory Committee and
 a Citizen's Advisory Committee. The
 GMP Office, eight technical issue
 committees, and the operations and
 support committees coordinate the
 collection, integration, and report-
 ing of pertinent data and informa-
 tion.
    The issue committees are
 responsible for documenting envi-
 ronmental problems and manage-
 ment goals,  available government
 and private resources, and potential
 solutions relating to specific issue
 areas. The issue committees are
 composed of individuals from Fed-
 eral, State, and local agencies and
 from industry, science, education,
 business, citizen groups, and private
 organizations. These committees
 cover a broad range of issues,
 including habitat degradation, pub-
 lic health, freshwater  inflow, marine
 debris, coastal and shoreline ero-
 sion, nutrient enrichment, toxics
 and pesticides, and living aquatic
 resources. They develop and present
their findings in GMP documents
called Action Agendas, which
describe strategies to  build upon
 programs already under way and to
 develop new cooperative mecha-
 nisms with other public and private
 organizations. The Action Agendas
 also provide strategies to monitor
 and assess the effectiveness of
 ongoing efforts and to communicate
 information to individuals and agen-
 cies that can  best use it. Two addi-
 tional committees provide opera-
 tional support for public education
 and outreach and data and informa-
 tion transfer activities for the entire
 GMP.

 Partnership for Action

    On December 10, 1992, EPA;
 the Governors of Alabama, Florida,
 Louisiana, Mississippi, and Texas; the
 Chair of the Citizens Advisory Com-
 mittee;  and representatives of 10
 other Federal agencies signed a Gulf
 of Mexico Program  Partnership for
 Action agreement for protecting,
 restoring, and enhancing the Gulf of
 Mexico and adjacent lands. The part-
 nership document includes vision
 and goal statements and nine 5-year
 challenges for the GMP. The goals
 established for the Gulf of Mexico
 Program are to protect, restore, and
 enhance the coastal and marine wa-
 ters of the Gulf of Mexico and its
 natural coastal habitats, to sustain
 living resources, to protect human
 health and the food supply, and to
 ensure the recreational use of Gulf
shores, beaches,  and waters in ways
consistent with the economic well-
 being of the region.
    The 10 environmental challenges
commit the signatory agencies to
pledge their efforts, over the next
5 years, to obtain the knowledge
and resources to

-------
                        Chapter Twelve The Watershed Protection Approach and Place-based Management Programs   311
•  Significantly reduce the rate of
loss of coastal wetlands
•  Achieve an increase in Gulf Coast
seagrass beds
•  Enhance the sustainability of Gulf
commercial and recreational fisher-
ies
•  Protect human health and the
food supply by reducing inputs of
nutrients, toxic substances, and
pathogens to the Gulf
•  Increase Gulf shellfish beds avail-
able for safe harvesting by 10%
•  Ensure that all Gulf beaches are
safe for swimming and recreational
uses
•  Reduce by at least 10% the
amount of trash on beaches
•  Improve and expand coastal
habitats that support migratory
birds, fish, and other living resources
•  Expand public education/out-
reach tailored for each Gulf Coast
county or parish
•  Reduce critical coastal and shore-
line erosion.

    The GMP structure has been
streamlined to better meet the
needs of the new 5-year environ-
mental challenges. In addition, EPA
has restructured its management
scheme for the GMP to increase
Regional involvement in the pro-
gram as it moves to implement
environmental protection and resto-
ration activities.
    The Gulf waters are impacted
not only by the United States, but
by Mexico and, to a lesser extent,
by islands in the Caribbean Sea. The
GMP has expanded  its activities to
provide support to this international
community. By promoting Special
Area Designation under MARPOL
Annex V, the Program has advanced
the emplacement of regulations to
reduce the discharge of ship-gener-
ated waste in the Gulf and Carib-
bean; the discharge of any plastics is
prohibited under Annex V. Addi-
tional assistance to Caribbean coun-
tries is provided through participa-
tion in the United Nations Environ-
mental Programme via  their Carib-
bean Environment  Program
(CEPPOL) and the Intergovernmen-
tal Oceanographic  Commission,
which focus on addressing land-
based sources of pollution for the
Caribbean.
    The GMP is also advancing
technology transfer with Mexico.
The Program  of Ecology, Fisheries
and Oceanography of the Gulf of
Mexico (EPOMEX)  participates in
the GMP's Living Aquatic Resources
committee and in other Program
activities. EPOMEX  is an agency that
coordinates the scientific research of
institutions of higher education in
the areas of the coastal zone and its
biological resources and the conser-
vation of the  marine environment,
coupling science with resource man-
agers and policy makers in the Gulf
of Mexico.

Take-Action Projects

    During 1992, the GMP
launched important environmental
projects in each of  the five Gulf
States to demonstrate that GMP
strategies and methods could
achieve positive results quickly.
Called  "Take-Action Projects," they
primarily address habitat protection
and restoration and public health.
They are designed for Gulf-wide
application to help restore the envi-
ronment.

                                     deal with pollution and contami-

Pollution Prevention

    The State of Mississippi has
developed a common sense publica-
tion entitled The Gulf of Mexico
Citizens Pollution Prevention Hand-
book. Written in nontechnical
language, the handbook describes
the Gulf of Mexico and explains
why it is a valuable resource to our
Nation's economy and quality of
life. This take-action guide provides
a detailed listing of contacts for
more information, and it explains
specific ways that everyone in the
Gulf region can be actively involved
in restoring and preserving the
environmental quality of the Gulf.

Habitat Protection

    Based on a Texas program
called Coastal Preserves, a GMP
Take-Action Project called Gulf Eco-
logical Management Sites (GEMS),
seeks innovative approaches to pro-
tect coastal tracts that have been
identified as important to the Gulf
ecosystem.  In some cases, areas
may be preserved as wilderness. In
others, they would be conserved-
that is, carefully monitored and
managed to maintain their vitality
as wildlife and marine life habitat
while being used for hunting,, fish-
ing, resource extraction, recreation,
or other development. Ideally, these
tracts would be under the manage-
ment and protection of a  govern-
ment agency or established environ-
mental organization.
    To promote the concept Gulf-
wide, the GMP sponsored a GEMS
Workshop in New Orleans to share

-------
                         Chapter Twelve  The Watershed Protection Approach and Place-based Management Programs   313
information about the need to
protect such areas; to discuss the
resources available to help manage,
preserve, or conserve them; and to
develop a strategy for generating
Gulf-wide support and funding for
protecting the most valuable of
these tracts.

•  Adopting this concept, Mississippi
established a Coastal Preserves Pro-
gram and set aside a donated por-
tion of the Graveline Bayou Estuary.
This area has been  placed under the
protection and management of the
State's Department of Marine Re-
sources.

•  Protection of oyster habitat is the
goal of a Take-Action Project in
Alabama. Oyster beds and reef sys-
tems in the shallow waters of
Mobile Bay, often harmed uninten-
tionally by boaters and fishermen,
have been marked with buoys and
signs to help boaters and fishermen
avoid damaging  them in the future.

Habitat Restoration

    The degradation (and in many
cases, complete disappearance) of
wildlife and marine life habitats is
one of the most  serious environ-
mental problems of the Gulf ecosys-
tem. Restoration  of these habitats is
the focus of numerous CMP Take-
Action Projects throughout the Gulf
Region. Wetlands, reefs, seagrasses,
and the quality of the water in these
habitats are among the most signifi-
cant concerns receiving immediate
attention.

Seagrass Beds

    One of several Take-Action
Projects in Alabama's Mobile Bay is
an innovative program to restore
damaged or destroyed seagrass
beds—a major habitat for fish,
shrimp, and crabs. A new approach
being developed is less costly and
labor intensive than current meth-
ods of transplanting from existing
seagrass beds. Seagrasses are germi-
nated from the seeds of wild plants,
grown in the natural environment
within protected mesh-covered
trays, then planted in designated
areas where seagrass beds are in
decline or are known to have once
existed. Low in cost and requiring
very little equipment or technical
knowledge, this program lends itself
extremely well to hands-on  partici-
pation by concerned citizens and
can be easily implemented
Gulf-wide.

Salt Marsh Wetlands

    Another Take-Action Project in
Alabama's Mobile Bay is the restora-
tion of a  salt marsh wetland on an
abandoned site near the Dauphin
Island Sea Lab.  A wildlife habitat
before the Civil War, this marsh
wetland was filled in and used for a
number of land uses including grave
sites and  large septic tank reservoirs.
The objective of this project is to
accelerate the natural reclamation
process of tidal action and provide a
model for future manmade  marsh
and wetlands areas. A team of sci-
entists is carefully monitoring the
marsh reconstruction (from  initial
sloping of the land and planting of
marsh and wetlands flora, to
rebuilding of the adjacent dune
system) and will conduct a long-
term evaluation of the habitat's
health and development. This
"living marsh" will also serve as an
outdoor exhibit for the nearby
Estuarium—a marine sciences
museum  intended to educate the

Oyster Beds

    In Louisiana, Florida, and Ala-
bama, the number of oyster reefs
that have been closed to harvesting
operations has steadily increased in
recent years due to bacterial
contamination from inadequately
treated human waste. The solution
is a series of Take-Action Projects to
install upgraded septic systems or
innovative sewage treatment sys-
tems in areas affecting the oyster
beds. In a few short years, these
low-cost, easy-to-install systems are
expected to revitalize oyster habitats
and help rebuild associated com-
mercial operations.

•  In Louisiana, the Nation's num-
ber one producer of oysters, a take-
action project in cooperation with
the National Estuary Program tar-
gets 240,000 acres of the Barataria-
Terrebonne Estuary that contain
68% of the State's private oyster
leases-an area increasingly closed to
harvesting. Likewise, the oyster-
producing areas near Suwannee
Sound and Appalachicola Bay
(Florida) and Weeks Bay (Alabama)
will benefit from similar projects to
improve sewage treatment systems.

•  Another Take-Action Project in
Alabama's Mobile Bay aims to
restore and create oyster habitat
with a certain type of Mexican coral
taken from dead reef deposits found
inland and used to form new living
reefs for young oysters to grow on.
This first-of-its-kind application of
such coral will shorten  the time it
takes for oyster reefs to form. If
successful, it could have far-reaching
impacts in reef restoration Gulf-
wide.

The Great Lakes Basin

Background:  Water Quality
in the Great Lakes

     Great Lakes water quality is
classically divided into two issues:
nutrients and toxicants. Together
with the  Great Lakes States and the
Province  of Ontario, the United
States and Canada have worked to
implement a broad strategy to
reduce loadings in both categories.
In addition, the two countries have
acted in acknowledgment of the
interrelationship among water qual-
ity and many other elements of the
ecosystem, including habitat and
community structure, and the
dynamics of exchange with the
atmosphere and sediments.
    During the past two decades,
the United States and Canada  have
corrected many of the nutrient
enrichment problems in the Great
Lakes region that attracted national
attention in the 1960s. Since 1970,
phosphorus detergent restrictions,
municipal sewage treatment plant
construction and upgrades, and
agricultural practices  that reduce
runoff have cut the annual phos-
phorus load into the  Great Lakes in
half.
    The decline in phosphorus load-
ings is most evident in Lake Erie,
which receives more  effluent from
sewage treatment plants and sedi-
ment from agricultural lands than
the other Great Lakes. Lake Erie also
experienced a concurrent decline in
phytoplankton biomass, an indicator
of trophic condition and nutrient
enrichment. This decline in

-------
                         Chapter Twelve The Watershed Protection Approach and Place-based Management Programs  315
phytoplankton biomass, accompa-
nied by dramatic improvements in
water clarity and greatly reduced
occurrences of anoxia in the Lake's
eastern basin, provides evidence that
the phosphorus controls imple-
mented in the 1970s and 1980s
have reversed Lake Erie's severe nu-
trient enrichment problems of the
1960s.
    This picture is complicated by
the recent invasion by, and profu-
sion of, the zebra mussel, an exotic,
or nonnative, species. Its impact is
not yet well quantified but is
believed to be substantial. The zebra
mussel is a very effective filter feeder
and is generally thought to have
had a profound effect on plankton
community structures in Lake Erie
and elsewhere in the Great Lakes
with concomitant changes in the
food chain as energy is rerouted into
the benthic (or bottom-dweller)
community. Recent invasions of
other exotic species, such as the
spring water flea (bythotrephes) and
two species of gobey, combined
with introductions of Pacific salmon
and the rusty crayfish, have dramati-
cally altered the structure of the
Great Lakes' communities.
    Despite dramatic declines in the
occurrence of algal blooms, fish kills,
and localized "dead" zones depleted
of oxygen, less visible problems
continue to degrade water quality in
the Great Lakes. The  States report
that toxic contamination is the most
prevalent and persistent water pollu-
tion problem in the Great Lakes. The
eight States bordering the Lakes
have issued advisories to restrict
consumption of fish caught along
their entire shorelines. Depending
upon location, mercury, RGBs, pesti-
cides, or dioxins are variously found
in fish tissues at levels that exceed
standards set to protect human
health. As a result, virtually all of the
waters along the Great Lakes shore-
line fail to fully support fish con-
sumption and therefore fail to fully
support overall designated uses
(Figure 12-2). The levels of most
organochlorine contaminants have
declined dramatically since control
measures began in the mid-1970s.
As a result, although the trend
seems to be leveling off, concentra-
tions of these contaminants in fish
tissue have declined. Toxaphene (or
toxaphene-like compounds), how-
ever, appears to be  running counter
to this trend in Lakes Superior and
Michigan, where fewer declines and
even some increases have appeared.
It is not clear, however, whether or
not this increase can be attributed
to historical use of the pesticide,
toxaphene, or if the increase is due
to the introduction of a similar com-
pound from an unidentified source.

Efforts are under way by the U.S.
EPA and Canada to determine the
source of the toxaphene and
toxaphene-like compounds.  Fish
consumption advisories  have been
issued for the Great Lakes due to
apparent "toxaphene."
    Although fish consumption use
is impaired throughout the Lakes,
more than  96% of the Great Lakes
shoreline fully supports recreational
uses and drinking water supply use
(Figure 12-3). However, in the well-
publicized outbreak of Cryptospor-
idiosis in 1993, storm flows carried
pathogens  from the Milwaukee
River uplands well into Lake
Michigan, where the pathogens
entered the Milwaukee municipal
drinking water intake, resulting in
over 100 deaths and thousands of
illnesses.
    The individual use support data
submitted by the States indicate
that the remaining problems on the
Lakes have the greatest impact on
fishing activities and aquatic life.
Aquatic life impacts include  de-
pleted fish  populations and repro-
duction problems in pisciverous
(fish-eating) birds (Table 12-1  and
box). Aquatic life impacts result
from persistent toxic pollutant bur-
dens in birds, habitat degradation
and destruction, and competition
and predation by nonnative species,
such as the zebra mussel and the
sea lamprey.
    The States reported that priority
organic chemicals (primarily PCBs)
are the most prevalent cause of
impairment in their Great Lakes
waters (Figure 12-4). These  toxic
chemicals persist in fish tissues, wild-
life tissues, and sediment. The States
reported much lower incidences of
metal contamination, depressed

                 Trends in PCB C^titaminatipn in the Great Lakes

     Research conducted by the United States and Canada in the Great lakes indicates that PCB concen-
 trations in wildlife have declined dramatically since :the EPA banned most uses of PCBs in 1976; However,
 the PCB concentrations in fish persist well above concentrations set to protect public health> and the   /
 persistent PCB burdens in some fish,, mammals, and birds still may impair reproductive success. For   /
 example, concentrations of PCBs in Lake Michigan lake trout declined by-about 90% since 1970, but
 remain at about 180 times the target goal of 0;014  parts per million. Similarly, body burdens ;of PCBs in
 a colony of Forster's terns near Green Bay, Wisconsin, declined by 66% while hatching success tripled
 between 1983 and 1988. However/the terns': offspring continued to suffer "wasting" and other fatal
 health problems, which may have: resulted from the contaminant burdens in the adult birds. For addi-
 tional information, see D. De Vault, D.tyl. Whittle,  and S. Rang, Tox/c Contaminants in the Great Lakes,     ;

                                          Only four of the eight Great
                                      Lakes States measured the size of

                                      the Great Lakes shoreline, so their
                                      findings do not necessarily reflect
                                      conditions throughout the Great
                                      Lakes Basin (Figure 12-5).

                                      • Wisconsin identified air pollution
                                      and discontinued discharges as
                                      sources of pollutants contaminating
                                      all 1,017 of their surveyed shoreline
                                      miles. Wisconsin also identified
                                      smaller areas impacted by contami-
                                      nated sediments, nonpoint sources,
                                      industrial and municipal discharges,

                                      and land disposal of waste.

                                      •  Indiana attributed all of the
                                      pollution along its entire 43-mile
                                      shoreline to air pollution, agricul-
                                      ture, and industrial and municipal
                                      discharges.

                                      •  Ohio reported that nonpoint

                                      waters, but the State attributes the
                                      most miles of degradation to
                                      contaminated sediments (439 miles)
                                      and land disposal of waste (374

Building Institutional
Frameworks for the
Great Lakes

    Rehabilitating the Great Lakes
requires cooperation from numerous
organizations because pollutants
originate in both Canada and the
United States as well  as other coun-
tries, and pollutants enter the Lakes
via multiple media (i.e., air, ground
water, and surface water). The Inter-
national Joint Commission  (IjC),
established by the 1909 Boundary
Waters Treaty, lays the foundation
of the institutional framework for
managing the Great Lakes. Under
the auspices of that Treaty, the
United States and Canada signed
the Great Lakes Water Quality
Agreement in 1978 (see further
discussion on page 322). Represen-
tatives from the Government; of the
United States and Canada, the Prov-
ince of Ontario, and the eight States
bordering the Lakes sit on  the IJC's
Water Quality Board.
     The IJC Water Quality Board
makes recommendations to the
United States and Canada  regarding
actions needed to maintain the
integrity of the Great Lakes ecosys-
tem. It provides various platforms
for addressing Great  Lakes issues.
The  Board also monitors and  reports
upon the progress of the two
nations in meeting their commit-
ments under the Agreement and
evaluates and comments upon their
environmental policies and actions.
    The EPA Great Lakes National
Program Office (GLNPO) coordi-
nates activities within the United
States at all government levels,
working with nongovernment
organizations to protect and restore
the Lakes. One vehicle for this coor-
dination is the joint Federal/State

-------
                         Chapter Twelve The Watershed Protection Approach and Place-based Management Programs   321
5-Year Strategy (1992-97) for Protect-
ing the Great Lakes. GLNPO provides
additional leadership through its
annual Great Lakes Program Priorities
and Funding Guidance. It also serves
as a liaison and provides information
to the Canadian members of the IjC
and the Canadian counterparts to
the EPA. GLNPO is responsible for
direct negotiations and cooperation
with Canadian Federal agencies
through the Binational Executive
Committee.
    The Great Lakes States and the
Federal agencies work together to
provide a broad  range of routine
monitoring of the Lakes and their
basin. The States and U.S. Geologi-
cal Survey perform most tributary
monitoring, and State agencies and
the U.S. Fish and Wildlife Service,
together with the National Biologi-
cal Service, collect tributary and
open  Lakes fish for contaminant
monitoring. GLNPO conducts
essentially all the United States'
open  Lakes water quality and sedi-
ment monitoring and carries out
contaminant analyses on fish
sampled by other agencies. It also
carries out, and is the primary fund-
ing source for, major special studies,
such as those for mass balance of
Lake Michigan and Green Bay.
    The Great Lakes governors have
worked together on a number of
common issues over the years. For
example, the Great Lakes Protection
Fund was formed by the Great
Lakes  Governors  in 1989. The mis-
sion of the  Fund is to identify, dem-
onstrate, and promote regional
action to enhance the health of the
Great Lakes ecosystem.  It is the
Nation's first multistate environmen-
tal endowment. The Great Lakes
States have pledged $100 million to
its permanent endowment.
    Public-private partnerships sup-
 port the institutional framework for
 managing the Great Lakes water
 quality. Special boards, commis-
 sions, and committees composed of
 representatives from universities,
 environmental organizations, agri-
 cultural interests, industry, shipping
 interests, and government play vital
 roles in coordinating policy and
 management decisions.  Some  of
 these groups focus on local areas
 and issues, while others  represent
 national organizations. To better
 coordinate their activities on the
 Great Lakes Basin, groups have
 begun to support umbrella organi-
 zations, such as Great Lakes United.
 Great Lakes United, started in 1982,
 represents more than 180 affiliated
 groups in the United States and
 Canada. One of its goals is to facili-
 tate citizen involvement in decision
 making processes. Other Great
 Lakes environmental organizations
 have a specific geographic focus,
 such as the  Lake Michigan Federa-
 tion, or concentrate on a narrower
 topical area, such as the Tip of the
 Mitt Watershed Council, which
 primarily addresses land  use issues
 (especially wetlands issues).
    The Great Lakes Commission is
 a binationally chartered indepen-
 dent organization that integrates
 environmental concerns  with
 economic development concerns.
The Commission's members are
 appointed by the States, Canadian
 Provinces, and both Federal govern-
 ments. The members issue reports
 on subjects such as the environmen-
tal impacts of transportation options
 in the Great Lakes Region. The
 reports provide data for  decision-
 making by the government bodies
with authority to manage the Lakes.
The Commission is working under a

cooperative agreement with GLNPO
to operate the Great Lakes Informa-
tion Network (GLIN), an Internet
Server. The GLIN provides a major
outlet and source for Great Lakes
environmental information.
    Private conservation groups are
also working with government
agencies to protect natural areas in
the Great Lakes Basin. GLNPO is
funding 69 restoration and protec-
tion projects based, in part, on find-
ings of the Great Legacy Project.
The Great Legacy Project, sponsored
to a considerable extent by GLNPO,
includes efforts by the Nature Con-
servancy of Canada and the United
States and other conservation
groups to pool natural heritage data
from several public agencies and
land trusts and to apply geographic
targeting approaches to identify
particularly high-quality resource
areas. Since 1992, GLNPO has insti-
tuted  and formalized a competitive
process to select high-priority on-
the-ground habitat protection, res-
toration, and remediation projects.
    In 1994, GLNPO completed a
statutory 6-year mandate, the
Assessment and Remediation of
Contaminated Sediments (ARCS)
Program, working with academic,
commercial, State, and local experts
to develop and test new sediment
remediation technologies. In  both
the habitat and sediment remedia-
tion arenas, it has organized signifi-
cant training events and confer-
ences to benefit both the public
and private sectors.
    In the fall  of 1994, GLNPO and
its Canadian counterpart in
Environment Canada, together with
the eight Great Lakes States,  the
Council of Great Lakes Industries,
environmental groups, and the
Province of Ontario, convened a
partnered endeavor to provide all
sectors of the Great Lakes commu-
nity with a synopsis of the state of
knowledge on the Great Lakes eco-
system. This  effort took two forms:
the State of the Lakes Ecosystem
Conference,  a major conference for
senior environmental managers, and
a set of six peer-reviewed draft topi-
cal papers and an integration paper.
The papers were presented at the
conference and designed to provide
a comprehensive snapshot of the
condition of  the Lakes' ecosystems.
   They provided a starting point
for a series of topical and Lake-by-
Lake discussions that became a
framework for interaction and com-
munication among disparate and
sometimes traditionally opposed
sectors.
   The draft papers are posted on
the Internet  GLIN server for public
access  and comment. Comments
from attendees  and the Great Lakes
community provided a final level of
review prior  to publication in mid-
1995. The conveners of the State of
the Lakes Ecosystem Conference
worked with the authors to  incorpo-
rate discussion and commentary
into the final papers.

The Great Lakes Water
Quality Agreement

   The 1978 Great Lakes Water
Quality Agreement (GLWQA), as
amended in  1987, established a
commitment by the United  States
and Canada  to  restore and protect
the Great Lakes. The Amendments
to the  Agreement stress two central
concepts: (1) the ecosystem
approach, and (2) the virtual elimi-
nation of persistent toxic
substances. The Agreement set a
limited number of ecosystem-based

-------
                         Chapter Twelve  The Watershed Protection Approach and Place-based Management Programs   323
 objectives for water quality, biota,
 habitat, and beneficial uses of the
 Lakes. The Agreement also institu-
 tionalized the Areas of Concern
 concept as well as commitments to
 develop Remedial Action Plans and
 Lakewide  Management Plans to
 address Great Lakes problems.
    Although there has been con-
 siderable progress in addressing
 impacts from point and  nonpoint
 loadings of conventional pollutants
 under the GLWQA, the Great Lakes
 are still  highly vulnerable to toxic
 pollutants. The IJC released a set of
 recommendations identifying 11
 "critical pollutants" for which man-
 agement scrutiny is warranted
 throughout the Basin. These chemi-
 cals and possible sources are
 presented in Table 12-2.

 The Great Lakes Water
 Quality Initiative

    The Great Lakes Water Quality
 Initiative (GLWQI) is a key element
 of the environmental protection
 efforts undertaken by the United
 States in the Great Lakes Basin. The
 purpose of the Initiative is to pro-
 vide a consistent level of protection
 in the Basin from the effects of toxic
 pollutants. This will further the
 national goal to restore, maintain,
 and protect the waters of this
 particularly valuable and sensitive
 ecosystem.
    On  March 23,  1995,  EPA pub-
 lished Water Quality Guidance for the
 Great Lakes System in the Federal
 Register (60 CFR 15366). EPA issued
the Guidance under the terms of
the Great  Lakes Critical Programs
Act of 1990. Now that the Guid-
ance is available, the next step  is for
the States and Tribes to incorporate
 provisions consistent with the
Guidance into their laws and regula-
tions within 2 years.

Foundations

    The GLWQI was organized by
EPA at the request of the Great
Lakes States in  1989. State gover-
nors had signed an agreement in
1986 to promote consistency in
their environmental programs for
the Great Lakes Basin. At the same
time, the governors had requested
that EPA facilitate these efforts to
promote consistency, and, in 1989,
the Council of Great Lakes Gover-
nors unanimously reaffirmed their
participation in the GLWQI, with
U.S. EPA Region 5 (Chicago, IL)
taking the lead role.
    The Initiative provided a forum
for a regional dialogue to establish
minimum requirements that would
reduce disparities  between State
water quality controls in the Great
Lakes Basin. The scope of the Initia-
tive included development of pro-
posed Great Lakes water quality
guidance for Great Lakes-specific
water quality criteria and method-
ologies to protect aquatic life, wild-
life, and human health; procedures
to implement water quality criteria;
and an antidegradation policy.

Organization and Process

    The open dialogue used in the
Initiative was exemplary and is a
model for the future. Three commit-
tees were formed  to carry out the
Initiative:

•  A Steering Committee (com-
posed of directors of water pro-
grams in the Great Lakes States'
environmental agencies and EPA's
National and Regional Offices)

discussed policy and scientific and
technical issues, directed the work
of the Technical Work Group, and
ratified final proposals.

• The Technical Work Group (con-
sisting  of technical staff from the
Great Lakes States' environmental
agencies, EPA, the U.S. Fish and
Wildlife Service, and the National
Park Service) prepared proposals on
elements of the Guidance for con-
sideration by the Steering Commit-
tee.

• The Public Participation Group
(consisting of representatives from
environmental groups, municipali-
ties,  industry, and academia)
observed the  deliberations of the
other two committees, advised
them of the public's concerns, and
kept its various constituencies
apprised of ongoing activities and
issues.

    From the start, one of the Com-
mittees' goals was to develop the
Guidance elements in an open pub-
lic forum, drawing upon the exten-
sive expertise and interest of indi-
viduals and groups within the Great
Lakes community.

Great Lakes Critical
Programs Act

    The Initiative efforts were well
under  way when Congress enacted
the Great Lakes Critical Programs
Act of  1990 to amend the Clean  '
Water  Act. The general purpose of
these amendments was to improve
the effectiveness of EPA's existing
programs in the Great Lakes. The
Act required EPA to publish pro-
posed  and final water quality
guidance that specifies minimum
requirements for waters in the
Great Lakes System in three areas:
(1) water quality standards (includ-
ing numerical limits on pollutants in
ambient Great Lakes waters to pro-
tect human health, aquatic life, and
wildlife; (2) antidegradation policies;
and (3) implementation procedures.
    The Act also requires  the Great
Lakes States to adopt provisions in
their programs that are consistent
with the final Guidance within
2 years of EPA's publication. In the
absence of such action, EPA is
required to promulgate any neces-
sary requirements within that 2-year
period. In addition, Indian Tribes
authorized to administer an NPDES
program or water quality standards
program in the Great Lakes Basin
will also need to adopt provisions
consistent with the final Guidance
into their water programs.
    To carry out the Act,  EPA pro-
posed regulations for implementing
the Guidance on April 16, 1993,
and invited comment from the pub-
lic. States and EPA conducted public
meetings in all the Great  Lakes
States during the comment period,
including two EPA public meetings.
As a result, EPA received over
26,500 pages of comments from
over 6,000 commenters.  EPA
reviewed all of this information in
developing the final Guidance that
was published in March of 1995.

Conclusion

    The final Guidance represents a
milestone in efforts by Great Lakes
stakeholders to define and apply
innovative and comprehensive envi-
ronmental programs for protecting
and restoring the Great Lakes. In
particular, the publication of the
final Guidance culminates 6 years of

-------

                                     intensive cooperative effort that
                                     included participation by the eight
                                     Great Lakes States, the environmen-
                                     tal community, academia, industry,
                                     municipalities, and EPA regional and
                                     national Offices.
                                         The final  Guidance will help
                                     establish consistent, enforceable,
                                     long-term protection with respect to
                                     all types of pollutants, but will place
                                     short-term emphasis on the types of
                                     long-lasting pollutants that accumu-
                                     late in the food web and pose a
                                     threat to the  Great Lakes System.
                                     The Initiative  Committees devoted
                                     considerable effort to identifying
                                     such chemicals—persistent bioaccu-
                                     mulative pollutants termed "bio-
                                     accumulative  chemicals of concern"
                                     (BCCs)—and  developing the most
                                     appropriate criteria, methodologies,
                                     policies, and procedures to address
                                     them. The special provisions for
                                     BCCs, initially developed by the
                                     Initiative Committees and incorpo-
                                     rated  into the final Guidance,
                                     include  antidegradation procedures
                                     to minimize future problems; gen-
                                     eral phaseout and elimination of
                                     mixing zones for BCCs (except in
                                     limited circumstances) to reduce
                                     their overall loadings to the Lakes;
                                     more  extensive data generation
                                     requirements  to ensure that BCCs
                                     are not  underregulated for lack of
                                     data; and development of water
                                     quality criteria that will protect wild-
                                     life that feed on aquatic  prey.
                                         The GLWQI also supports more
                                     comprehensive management plans
                                     for the Great  Lakes envisaged by
                                     the Great Lakes Water Quality
                                     Agreement of 1987 between the
                                     United States  and Canada. Lakewide
                                     Management Plans (LaMPs) for each
                                     Great Lake and Remedial Action
                                     Plans (RAPs) for each of 42 Great
                                     Lakes  "Areas of Concern" are under
development by EPA, the States,
local governments, and Canada.
The GLWQI contributes to the
implementation of all of these
efforts because it defines levels of
protection needed for any pollutant
that might threaten the Great Lakes.
    The GLWQI represents a part-
nership between the States and
Federal government to protect this
unique national resource. EPA is
currently providing technical assis-
tance to the States. Over the past
20 years great progress has been
made to improve the quality of
water in the Great Lakes, and the
GLWQI represents a further step in
ensuring the health and  quality of
the Great Lakes in the future.

Remedial Action Plans
for Areas of Concern

  -  Implementing control measures
for  pollutants usually begins in
smaller drainages and waterbodies.
At the smallest geographic scale, the
IJC  initially identified 42 Areas of
Concern (AOCs) located primarily
along river mouths or  harbors
where beneficial  uses were
impaired. Altogether, the IJC identi-
fied 14 types of use impairment
ranging from limitations  on use of
water for commerce to fish con-
sumption restrictions, reproductive
problems among wildlife, and
restrictions  on disposal of dredged
sediments.
    The United States  later desig-
nated Presque Isle Bay (in Pennsyl-
vania) as the 43rd AOC,  but Canada
delisted Collingwood Harbor (in
Ontario), returning the total number
of AOCs to 42. The United States
and Canada designated all 42 as
AOCs, all of which face major toxics
concerns. Thirty-five of the 42 AOCs

report toxics concerns in ambient.
water, 41 of 42 report toxics in
sediments, and 38 of 42 AOCs
restrict consumption of fish har-
vested from local waters because of
elevated toxic concentrations in fish
tissues.
    In 1985, the Great Lakes States
and the Canadian Provinces agreed
to develop and implement a Reme-
dial Action Plan for each AOC. In
1987, the United States and
Canadian Federal Governments
incorporated the commitment to
develop RAPs into the Great Lakes
Water Quality Agreement. A com-
plete RAP encompasses the follow-
ing stages and has a planning docu-
ment associated with each mile-
stone:

STAGE 1 - Identifies the  nature of
the problem(s) and summarizes
available information.

STAGE 2 - Specifies remedial and
regulatory measures needed to
restore beneficial uses.

STAGE 3 - Measures and summa-
rizes results as progress is achieved
in implementing management
plans.

    Of the 32 U.S. RAPs, 5 had
been completed through Stage 2
and 19 others had been  completed
or nearly completed through Stage
1 by the end of 1994.
    One of the RAPs, Fox River/
Green Bay, faced particular difficul-
ties in identifying the comparative
significance of various sources of
certain contaminants, especially
PCBs. In an unprecedented partner-
ship, GLNPO joined with the Office
of Research and Development,
several State agencies in  Wisconsin
and Michigan, other Federal agen-
cies, and several academic institu-
tions, to sponsor the Fox River/
Green Bay Mass Balance Study from
1987 through 1994. This study
demonstrated the feasibility of the
mass balance approach for identify-
ing the relative contributions to
toxicant-induced environmental
problems, and it provided the RAP
committee and the State of Wiscon-
sin with a unique tool to forecast
the effects of proposed environmen-
tal management decisions.

Lakewide Management Plans

   Lakewide Management Plans
are the next level of geographic
integration envisioned in  the Great
Lakes Water Quality Agreement.
These plans are whole lake planning
efforts. Under the Agreement,
LaMPs are to employ an ecosystem
approach founded on the same use
impairments forming the basis of
the RAP process. While focusing
primarily on the effects of toxics,
the LaMPs will also address habitat
and nutrient concerns. Public
involvement is a critical element in
LaMP development.
   The first effort at lakewide man-
agement was the Lake Ontario
Toxics Management Plan (LOTMP),
undertaken via a 1987 Declaration
of Intent (known as the "Four-Party
Agreement") among the  U.S. EPA,
Environment Canada, New York
State Department of Environmental
Conservation, and the Province of
Ontario. This Agreement  antici-
pated, in many respects, the LaMP
concept expressed in the 1987 revi-
sions to the GLWQA. The LOTMP
effort is chaired by EPA Region 2.
The Plan first developed a list of
critical pollutants for Lake Ontario in

-------
328  Chapter Twelve The Watershed Protection Approach and Place-based Management Programs
                                     1989. The "Four Parties" agreed at
                                     that time to undertake revisions that
                                     would permit the LOTMP to
                                     become the LaMP for Lake Ontario.
                                     Since then, there  have been two
                                     major revisions of the LOTMP and,
                                     in August 1994, GLNPO and Region
                                     2 cooperatively undertook an  inten-
                                     sive month-long special study moni-
                                     toring organic contaminants in the
                                     water and sediments of Lake
                                     Ontario. Public hearings on the first
                                     draft of the Plan as a Stage 1  LaMP
                                     are under way.
                                         The United States has prepared
                                     the LaMP for the  Lake Michigan
                                     Basin, which is contained entirely in
                                     this country. The effort is headed
                                     up  by EPA Region 5 and involves all
                                     of the Lake Michigan States: Wis-
                                     consin, Illinois, Indiana, and Michi-
                                     gan. Although impacts from nutri-
                                     ents and un-ionized ammonia toxic-
                                     ity persist, most of the problems in
                                     Lake Michigan stem from toxic
                                     contaminants already in the Lake
                                     system and ongoing toxic loadings
                                     from point and nonpoint sources.
                                     Future iterations of the LaMP will
                                     address all 14 beneficial use impair-
                                     ments.
                                         Building on work in progress at
                                     the various AOCs, the Lake
                                     Michigan LaMP will look at the lake
                                     ecosystem as a whole and identify a
                                     set  of critical pollutants. In some
                                     cases, this is a subset of the range
                                     of pollutants being addressed  at
                                     smaller geographic units such as the
                                     AOCs. In other cases, pollutants
                                     that are not of the highest concern
                                     in localized areas but are deemed
                                     critical to the entire Lake Michigan
                                     ecosystem may warrant scrutiny.
                                     The LaMP will propose a tiered
                                     concept for developing manage-
                                     ment actions.
    Currently, there is a major effort
 under way on the part of GLNPO
 with the assistance of the Office of
 Research and Development Environ-
 mental Research Laboratory-Duluth,
 Region 5, and the Lake Michigan
 States (Wisconsin, Illinois, Indiana,
 and Michigan) to carry out a full-
 scale mass balance study of Lake
 Michigan. This Study, begun in the
 spring of 1994, is an effort to pro-
 vide the LaMP  with a more defini-
 tive understanding of loadings and
 fates of four toxic substances (PCB
 congeners, trans-nonachlor, atra-
 zine, and mercury). It will project
 the effects of various management
 scenarios selected by the LaMP
 Management Committee. The Stage
 1  Lake Michigan LaMP first draft
 was published  in January 1992 and
 revised in September 1993. A final
 version is anticipated by the end of
 1995.
    The LaMPs for each Great  Lake
 will also encourage pollution pre-
'vention approaches. Lake Superior
 provides perhaps the best opportu-
 nity to implement pollution preven-
 tion because it is the least impacted
 of the Great Lakes.  Lake Superior
 has been spared much of the
 extreme ecological disruptions  asso-
 ciated with industrial and municipal
 discharges,  introduction of exotic
 species, and overharvesting of the
 fisheries that have had  devastating
 impacts on the lower Great Lakes,
 especially Lakes Ontario and Erie.
    In the  Fall of 1991, the United
 States, Canada, and the States of
 Minnesota, Wisconsin,  and Michi-
 gan and the Province of Ontario
 formally agreed on a new regional
 agreement to protect Lake Superior
 from toxic pollution. The Binational
 Program seeks to encourage

-------
                        Chapter Twelve The Watershed Protection Approach and Place-based Management Programs  329
pollution prevention and expand
authorities (where appropriate) to
implement a goal of zero pollutant
discharge and emission of nine per-
sistent bioaccumulative toxic sub-
stances. As a first step, both the U.S.
and the Canadian governments will
work to freeze loadings of toxic
discharges. The United States and
Canada issued a draft Stage 1 LaMP
for Lake Superior in February 1994
and expect to transmit a Stage 1
version incorporating public com-
ments to the IJC in the near future.
A draft Stage 2 LaMP is expected to

    The LaMP for Lake Erie is now
in the early stages of development
with a binational Management
Committee and Workgroup in
place. The Workgroup, under the
direction of the Management Com-
mittee, has begun developing eco-
system objectives and assessing the
status of beneficial uses for Lake
Erie. The Workgroup has also initi-
ated a variety of public involvement
activities, including developing a
Lake Erie Forum and  requesting
comments on a concept paper
outlining the LaMP framework.

Pollution Prevention
Initiatives

    The EPA GLNPO is working with
EPA Regions 2,  3, and 5, the States,
and their Canadian counterparts to
promote pollution prevention as the
most effective approach to achieve
the GLWQA goal of virtually elimi-
nating discharges of  persistent toxic
substances in the Great Lakes. In
1991, EPA and  the States developed
the Great Lakes Pollution Prevention
Action Plan to highlight how EPA
and the States will minimize the
use, production, and release of toxic
substances at the source. The Ac-
tion Plan targets persistent
bioaccumulative toxic substances for
reduction or elimination.
    The GLNPO has allocated sig-
nificant funding and developed a
formal process for funding numer-
ous pollution prevention grants
throughout the Great Lakes Basin
for the past 3 years. The three
Great Lakes Regions of EPA are us-
ing the pollution prevention ap-
proach to prioritize solutions. The
Regions view pollution prevention
as a voluntary program that falls
back on regulation as needed. The
1992 program goal was surpassed
by over 100 million pounds in re-
duced contaminant releases into the
environment.
    The EPA Regions and Great
Lakes States are implementing the
National 38/50 Program in the
Great Lakes Basin. Under this pro-
gram, EPA has received voluntary
commitments frpm industry to
reduce the emission of 17 priority
pollutants by 50% by the end of
1995. This goal is expected to be
achieved ahead of schedule. As part
of the Binational Program to Protect
Lake Superior, EPA and the States
are also cooperating with Canada
to undertake a virtual elimination
initiative for Lake Superior that seeks
first to eliminate new  contributions
of Great Lakes critical  pollutants,
with special  emphasis on  mercury.
The EPA is also working with utilities
located within the Great Lakes Basin
to accelerate the phaseout of trans-
formers containing PCBs.

                                   State, and local participants that has

    Considered a national and inter-
 national model for estuarine restora-
 tion and protection, the Chesapeake
 Bay Program is still a "work in
 progress." Since 1983, milestones in
 the evolution of the program
 include the 1987 Chesapeake Bay
 Agreement, which set a goal of a
 40% reduction of nutrients entering
 the Bay by the year 2000. In the
 1992 amendments to the Agree-
 ment, the partners reaffirmed the
 40% nutrient reduction goal,
 agreed to cap  nutrient loadings
 beyond the year 2000, and agreed
 to attack nutrients at their source by
 applying the 40% goal to the 10
 major tributaries of the Bay. The
 agreements have also stressed
 management of the Bay as a whole
 ecosystem, using the restoration of
 both habitat and living resources as
 measures of  progress.
    Federal agencies also play a
 significant role  in the Chesapeake
 Bay Program. The Federal Govern-
 ment owns 1.6 million acres of land
 in the Bay watershed. In 1994,
 officials from 25 Federal agencies
 and departments signed the Agree-
 ment of Federal Agencies on Ecosys-
 tem Management in the Chesa-
 peake Bay. This Agreement set out a
 number of specific goals and com-
 mitments for Federal agencies on
 their lands throughout the water-
 shed, as well as new cooperative
 efforts by Federal agencies else-
 where.
    The Chesapeake Bay is an enor-
 mously complex and dynamic sys-
 tem of fishes, waterfowl, and veg-
 etation  in an estuary where salt
water from the Atlantic Ocean and
fresh water from the many tributar-
 ies of the Bay come together (Figure
 12-6). A host of complicated inter-
actions  having  physical, chemical,

and biological dimensions present
formidable challenges to the under-
standing and management of this
great estuary (Figure 12-7).
    If we liken the Chesapeake Bay
to a patient in the hospital under-
going treatment for a life-threaten-
ing illness,  we can now report that
the patient's vital signs, such as
living resources, habitat, and water
quality are stabilized and the patient
is out of intensive care. Some vital
signs, such as striped bass and Bay
grasses have  improved dramatically,
others, such as oysters, are still in
danger, with still other vital signs
mixed but stable. Nutrient levels
continue on their downward slope,
with phosphorus reduction outstrip-
ping that of nitrogen. Dissolved
oxygen  remains unchanged but has
stopped declining. In the following
sections, these findings are exam-
ined in more detail.

                                     Land Use

                                         The Chesapeake Bay's water-
                                     shed, radically changed by Euro-
                                     pean settlement three centuries ago,
                                     continues to undergo changes that
                                     reflect how we use the land in this
                                     64,000-square-mile expanse. Urban,
                                     suburban, and agricultural lands all
                                     leach more pollutants into the Bay
                                     than do natural forests and wet-
                                     lands. About 40% of the land is no
                                     longer in its natural state and we
                                     are losing wetlands at a rate of
                                     8 acres per day.
                                         Data from 1990 show that for-
                                     est is the dominant land use within
                                     the Bay watershed, constituting
                                     about 59% of the land, mostly in
                                     areas far removed from the  Bay's
                                     shoreline. Agricultural land, includ-
                                     ing pasture and cropland, consti-
                                     tutes about 33% of the watershed.
                                     Urban and suburban lands are gen-
                                     erally close to the Bay and its tidal
                                     tributaries and cover about 7% of
                                     the watershed. Wetlands, critical
                                     habitat environments, represent
                                     about 1 %. Nutrient and sediment

                                     uses.
                                         Based on  projections of  a
                                     steadily increasing population, the
                                     largest change in land use will be
                                     from forest and agriculture to urban
                                     and suburban. In 1985, about 4.0
                                     million acres of the watershed were
                                     urban or suburban. This number is
                                     projected to increase to about 5.4
                                     million acres by the year 2000, an
                                     increase of 35% over the 1985 acre-
                                     age. Between  1982 and 1989,
                                     20,000 acres,  about 2.5% of wet-
                                     lands, were lost primarily through
filling, draining, or conversion to
open water. This represents a loss of
about 8 acres per day.

Population

    Population growth is the single
most important factor underlying
the various stresses on the Bay eco-
system. In 1950, the Bay's water-
shed contained 8.4 million resi-
dents. By 1990, this figure had
grown to 14.2 million and, by
2020, there will be an estimated
17.4 million people living in the
watershed. An expanding
population relies on highways and
automobiles, increasing both the
number of cars on the road and the
miles driven. The growing popula-
tion also requires land for homes,
transportation, shops, jobs, and
recreation.  Forests and other lands
of environmental significance are
often converted to meet these
needs.
    An ever-increasing population
has resulted in higher wastewater
flows to the Chesapeake Bay (Figure
12-8). As a result of improved
wastewater treatment and bans  on
detergents containing phosphorus,
point source loads of phosphorus
have been reduced by 70% since a
peak in the 1970s, despite a 40%
increase in total flow. Nitrogen con-
trols, just recently implemented, are
already starting to reduce the levels
of this pollutant entering the Bay
from point sources such as industry
and municipal sewage treatment
plants.
    Along with changes in land  use,
population  growth also results in
higher flows from wastewater treat-
ment plants.  This wastewater con-
tains the nutrients phosphorus and

-------
                        Chapter Twelve  The Watershed Protection Approach and Place-based Management Programs  333
nitrogen, excessive quantities of
which are the primary pollution
threats facing Bay waters. The Fed-
eral Construction Grants Program
provided improved treatment at
municipal plants to remove phos-
phorus, resulting in a sharp decline
in phosphorus discharges between
1970 and 1980. These reductions
have continued  since 1980 with
additional treatment plant upgrades
and the implementation of phos-
phorus bans that prohibit the use of
this nutrient in household deter-
gents. Overall, phosphorus  loads
have declined by about 70% since
the 1970s. Nitrogen discharges
increased steadily between  1950
and 1985. Improved treatment at
both industrial and municipal waste-
water facilities is responsible for
reductions in nitrogen discharges
since 1985. Innovative technologies,
such as biological nutrient removal
(BNR) provide better management
of the sewage treatment process,
resulting in lower nitrogen and
phosphorus levels.
    The signatories of the Chesa-
peake Bay Agreement have commit-
ted to develop and implement nu-
trient reduction  strategies—the
Tributary Strategies—that will
reduce the 1985 combined point
and nonpoint source loads  by 40%
by the year 2000. Great strides have
been made in reducing point source
phosphorus loads. Continued reduc-
tions are needed,  especially in nitro-
gen, however, to offset flow
increases in areas of  rapid popula-
tion growth.
Impacts on the Ecosystem

Rivers - Nutrient and sediment
pollution from the Susquehanna
and Potomac Rivers, the two largest
freshwater tributaries feeding the
Bay, show encouraging signs. After
many years of increasing nitrogen
concentrations, most of the Bay's
tributaries are showing a leveling off
of this trend and some are actually
showing a decline (Figure 12-9).
Such results demonstrate that point
and nonpoint source abatement
programs instituted over the past
10 years are producing the desired
results.
   The quality of fresh water enter-
ing the Chesapeake  Bay from the
surrounding nontidal tributaries is
an important factor in the water

the mid-1980s have clearly contrib-
uted to the lowering of phosphorus
inputs from the rivers. Even nitro-
gen, which has only recently been
targeted for load reductions is
showing declines in parts of the
Susquehanna and Patuxent Rivers.

Estuaries - Nutrient levels in the
tidal saline waters of the Chesa-
peake Bay  and its tributaries are
responding to the trends seen in
the inputs  of nutrients from the
nontidal rivers (Figure 12-10). Many
regions are showing declines in
phosphorus levels.  Nitrogen flowing
into the Bay has stopped increasing
in most areas. Despite these
promising trends, dissolved oxygen
levels are still low enough to cause
severe impacts and  stressful condi-
tions  in the mainstem of the Bay
and several of the larger tributaries
(Figure  12-11).
    The main  causes of the Bay's
poor water quality and aquatic habi-
tat loss  are elevated levels of the
nutrients nitrogen and phosphorus.
Both are natural fertilizers found in
animal waste,  soil, and even the
atmosphere. In excessive amounts,
these nutrients cause an excessive
growth  of algae, which clouds the
water and  blocks the sunlight that is
essential for submerged aquatic
grasses. When the algae die, they
sink and decompose, using up the
dissolved oxygen in the water. Low
oxygen conditions  may cause the
eggs and larvae of fish to die. The
growth  and reproduction of oysters,
clams, and other bottom-dwelling
animals are impaired. Adult fish find
their habitat reduced and their feed-
ing inhibited. Animals that cannot
move may die.
    Nitrogen concentrations in the
water appear to be  declining in
some areas, especially Maryland's

upper western shore, the Patuxent
River, and the James River in
Virginia. In all areas of the Bay and
its tributaries, phosphorus concen-
trations are either declining or have
remained stable since 1984.
Changes in dissolved oxygen condi-
tions are few and do not show any
consistent pattern. The observed
changes are primarily due to
improved treatment at industrial
and municipal point sources located
in the major metropolitan areas that
surround the upper tidal tributaries.

Living Resource Response

Submerged Aquatic Vegetation -
Submerged aquatic vegetation
(SAV), a critical habitat for fish,
crabs, and waterfowl, has increased
75% since 1978 in response to
improving water quality (Figure 12-
12). These increases  achieve about
64% of the initial restoration  goal.
Survey results for 1994 show a 10%
decrease in the acreage of SAV due
largely to record freshwater flows in
spring that transported increased
nutrient and sediment loads into the
Bay. Additional improvements in
water quality will be needed to
sustain the resurgence in SAV.
    The strong link between water
quality and SAV distribution and
abundance makes SAV plant com-
munities good barometers of the
Chesapeake Bay's health. SAV his-
torically covered vast areas of the
Bay's shallow waters  and nurtured a
rich variety of Bay life. During the
late 1960s and early 1970s, how-
ever, Bay SAV populations experi-
enced a dramatic decline due to
increased nutrient and sediment
pollution from development within
the watershed.
    Significant progress has been
made in defining water quality
requirements for SAV in the Bay.
Those requirements emphasize
good water clarity and low levels of
suspended sediment, nutrients, and
algae. The Chesapeake Executive
Council used this new information
about SAV in 1993 to  establish an
SAV restoration goal of 114,000
acres Bay-wide.

                                         Recent changes in Chesapeake
                                     Bay SAV populations suggest that
                                     most of these populations can
                                     rebound rapidly if water quality
                                     conditions are improved and main-
                                     tained. Some areas may not
                                     become revegetated even after the
                                     return of suitable water quality con-

                                     Bay,  such as plankton and  benthos,
                                     reveal underlying concerns in the
                                     food web that sustain some of the
                                     more visible Bay species. Zooplank-
                                     ton describes the community of
                                     floating, often microscopic animals
                                     that  inhabit aquatic environments.
                                     Zooplankton are the most plentiful
                                     animals in the Chesapeake Bay and
                                     its tributaries. The most common
                                     zooplankton are the Crustacea,
                                     which include animals such as crab
                                     and barnacle larvae.
                                        Zooplankton are proving to be
                                     good indicators of water quality
                                     conditions, habitat quality for living
                                     resources, and the effects of toxic
                                     contamination in the Bay. Several
                                     studies have indicated that sufficient
                                     numbers of zooplankton during the
                                     critical life stages of larval striped
                                     bass  are vitally important to their
                                     growth and survival. Zooplankton
                                     act as a critical link between water
                                     quality and living resources, and

                                     ment for use in assessing the health
                                     of the Chesapeake Bay.
                                        Phytoplankton refers to the
                                     community of floating, mostly
                                     microscopic plants or algae that
                                     inhabit aquatic environments. They
are a critical component of the
Chesapeake Bay ecosystem and
represent the first biological
response to the Bay's nutrient
enrichment problem.  Phytoplank-
ton are particularly important to the
Bay ecosystem because they are
primary producers, converting
energy from sunlight into food for
animals such as zooplankton, oys-
ters, and fish. Although phytoplank-
ton form the foundation of the food
chain in the Bay, problems can
occur if this community grows  out
of control due to excess nutrients.
    "Benthos" describes an inverte-
brate community of organisms  that
live on or in the bottom sediments.
This community includes a wide
variety of organisms such as clams,
oysters, and small crustaceans,  in
addition to the blood and  clam
worms commonly used as bait.
    Because most benthic inverte-
brates  have limited mobility and
cannot avoid changes in habitat
quality, they are often used as
reliable and sensitive environmental
indicators. Some benthic organisms
are commercially important and all
have important functions in the Bay
ecosystem. They act as nutrient
recyclers  and important links in the
Bay's food chain, feeding on  micro-
scopic  plankton and serving as  food
for the bottom-feeding blue crab
and fish such as spot and croaker.
    Most of the areas with severely
or moderately  degraded benthic
communities are located in deeper
tributary channels and the deep
trench  of the Bay and experience
stress from low concentrations of
dissolved oxygen.  Sediment concen-
trations of toxic substances appear
to have a secondary, but significant,
influence on benthic community
condition, primarily in industrialized

    Results indicate that implemen-
tation of the 1972 Clean Water Act
resulted in large reductions in the
quantity of contaminants discharged
through industrial wastewater
outfalls or sent to municipal waste-
water plants and ultimately to
Chesapeake Bay. Generally, con-
taminant concentrations in the sedi-
ment have been substantially
reduced in the past two decades.
Subsequent revisions of the Clean
Water Act and the Clean Air Act
required additional measures to
reduce the discharge of trace metal
and organic contaminants and pre-
vent toxic impacts.
    The Chesapeake Bay Program
recently completed evaluating its
toxic substances reduction strategy
to better define the nature, extent,
and magnitude of toxics problems
in the Chesapeake Bay.

Striped Bass - Due to improved
reproduction and better control of
the harvest, striped bass, also
known as rockfish, have made a
remarkable recovery over the past
decade. The increasing numbers of
striped bass (Morone saxatilis) seen
darting through Bay waters are a
tribute to interagency cooperation
in the management of an important
Bay resource. Monitoring data show
that significant progress has been
made in rebuilding the population
from the all-time lows  of the 1980s
(Figure 12-13). Striped  bass spend
most of their adult life in the ocean,
returning each spring to spawn in
tidal fresh or brackish waters found
along the Atlantic coast, with the
principal spawning and nursery
areas found in the Chesapeake Bay.
The increased abundance of striped
bass is due largely to the implemen-
tation of coastwide fishing
restrictions, including a fishing ban
in Chesapeake Bay, allowing more
fish to reach sexual maturity.

Shad - American shad, which
spawn in the Bay's tributaries, have
suffered population declines over
the past century from overharvest-
ing, dam construction that blocks
migration  routes, and habitat degra-
dation. Once one of the most com-
mercially valuable species in the
Chesapeake Bay, American shad
(Alosa sapidissimd) populations have
declined to a shadow of their
former abundance. Historical over-
harvesting and habitat degradation,
combined with stream impediments
blocking miles of spawning and
nursery  grounds, have been cited as
the main causes for this reduction.
    Due to declining stocks, Mary-
land placed a moratorium on shad

                                     Columbia also placed a moratorium
                                     on American and hickory shad  in
                                     1989 and Virginia imposed a mora-
                                     torium in 1994. None of these man-
                                     agement decisions affect the coastal
                                     "intercept" fishery, which continues
                                     to harvest the species all along the
                                     Atlantic coast, although Maryland
                                     has proposed to end the coastal
                                     fishery in 1995.

                                     survey improvement. Through these
                                     efforts, managers and researcheis
                                     hope to restore a once valuable
                                     species to its former abundance in
                                     the Bay.
                                         An integral component of the
                                     shad's long-term success is its ability
                                     to return to its upstream spawning
                                     habitat. The removal of blockages

                                     projects are under way. The Bay
                                     Program has committed to reopen-
                                     ing  582 miles of stream habitat by

                                     Blue Crab - The blue crab is cur-
                                     rently the most important commer-
                                     cial  and recreational fishery in the
                                     Bay. With increasing fishing pres-
                                     sures and relatively low harvests in
recent years, there is growing
concern for the health of the stocks.
Both Maryland and Virginia have
recently implemented new regula-
tions on commercial and recre-
ational crabbers to protect this
important resource.
    With the decline of other spe-
cies in the Bay and  the resultant
increase in  crab harvesting pressure,
concern about the future of this
great resource is mounting.
    A priority for improving man-
agement of the blue crab fishery is
to enhance our understanding  of
crab population dynamics. Knowl-
edge of both environmental  and
anthropogenic factors contributing
to annual fluctuations in reproduc-
tive success and population levels is
essential for effective fishery man-
agement.
    As with other Chesapeake Bay
fisheries,  a comprehensive approach
to managing the blue crab is
needed because biological, physical,
economic, and social aspects of the
fishery are shared among the Bay's
jurisdictions. To provide such an
approach, a Bay-wide blue crab
fishery management plan was devel-
oped  in 1989  to sustain the ecologi-
cal and economic value of the blue
crab stock.  The plan has already
resulted in the implementation of
better fishery practices and more
effective monitoring of the blue
crab stock,  as mentioned previously.
A revised plan  based on  more
accurate data and requiring further
conservation measures will be
completed  in 1995.

Oysters - Prospects for the Bay's
oyster population remain poor.
Overharvesting, habitat loss, and
disease have all conspired over the
years to deplete the stocks severely.

-------
                        Chapter Twelve  The Watershed Protection Approach and Place-based Management Programs   341
New management efforts have been
developed to improve this situation.
    Oyster harvesting has been an
integral part of the Bay region's
economic development and cultural
heritage. The filtering capabilities of
the oyster enable it to remove large
quantities of algae  and sediment
from the water column, while its
shells provide habitat for a variety of
benthic organisms  and fish species.
Some scientists feel that the restora-
tion of this creature is an  important
key to  improving water quality and
the overall health of the Bay.
    In  1989 the  Chesapeake Bay
Program established an oyster man-
agement plan with the goal of con-
serving oyster stocks while maintain-
ing a viable fishery. In the latest
effort to restore oyster stocks in
Maryland, 40 representatives includ-
ing watermen, academics, State
officials, environmentalists, and
aquaculturists joined in an Oyster
Roundtable to address the oyster's
dilemma. These discussions led to
the signing of an "action  plan" with
several recommendations for aqua-
culture, research, and the designa-
tion of special "recovery areas."
This management plan is  the first of
its kind to recognize the ecological
importance of the oyster in addition
to its commercial value.

Waterfowl - The Bay's waterfowl
consist of several species,  not all of
which are indigenous. A long-term
decline in the abundance of the
native waterfowl is of great concern.
The necessary corrective action to
reverse this trend is habitat improve-
ment and resurgence of SAV.
    Historically, waterfowl were so
abundant they seemed to blanket
areas of the Bay. Today, their
numbers are greatly reduced.
Widespread deterioration of shallow
water habitats and wetlands,
coupled with increasing human
disturbance, have reduced the abil-
ity of many Bay areas to support
waterfowl. Overall, waterfowl  are
declining in the Bay, with the larg-
est declines occurring in the Canada
goose population. The  black duck
continues its gradual decline,  as do
scooters, oldsquaw, and goldeneye.
Merganser, bufflehead, mallard, and
the nonindigenous mute swan
populations are increasing.

Conclusions

    The connection between
human activities on land and
Chesapeake Bay degradation is
clear. Overharvesting also contrib-
utes to declines in the Bay's living
resources. While the findings in this
report allow for much optimism,
they also warn that we are far from
declaring victory in  our fight to save
the Chesapeake Bay. The results
show that the Chesapeake Bay is an
interconnected system  and that
activities on the land and misman-
agement of the resources can set off
a chain of events that ultimately
yields degraded conditions in  the
water and loss of living resources.
The  results also show that these
conditions, which have resulted
from almost 300 years  of abuse, are
reversible.
    Overall, the Chesapeake Bay still
shows symptoms related to stress
from an expanding population and
the changes such growth brings
about in land  use. However, the
concentrated restoration and  man-
agement effort begun 12 years ago
has produced  tangible  results—a
state of the Chesapeake Bay that is
better today than it was when we

started—and promises the future
will be even brighter.
    We cannot return the Chesa-
peake Bay to its pristine, or original,
state, nor will we ever have the
uninhabited expanses that our par-
ents and grandparents knew. We
will probably never go back to the
days when we could harvest oysters
by the tens of millions of bushels
nor to the  days when we could
catch as many 40-pound rockfish as
our boat could hold. Those days are
gone forever. But, we can have
relatively clean water and large,
protected areas of marsh and shore-
line. We can have viable fish and
bird populations, although never
the "limitless" stocks of fish for all to
harvest. The lessons we learn from
these experiences, and our willing-
ness to act on them, will determine
the state of the Chesapeake Bay
that we leave to future generations.

The National Estuary
Program

    The National Estuary Program
embodies the ecosystem approach
by building coalitions, addressing
multiple sources of contamination,
pursuing habitat protection as a
pollution control mechanism, and
investigating cross-media transfer of
pollutants from air and soil into
estuarine waters.
    Congress recognizes that estuar-
ies are unique and endangered eco-
systems and that traditional water
pollution control programs alone
cannot address the more complex
issues associated with estuaries.
These issues include protecting
living resources and their habitats,
controlling  diffuse sources of pollut-
ants, and managing estuaries as
watershed ecosystems. Responding
to the unmet needs of estuarine
ecosystems, Congress established
the National Estuary Program in
1987 under Section 320 of the
Clean Water Act.
    The NEP adopts a geographic,
basinwide approach to environmen-
tal management. A State governor
nominates an estuary in his o>r her
State for participation in the  pro-
gram. The State must demonstrate
a likelihood for success in protecting
candidate estuaries and provide
evidence of institutional, financial,
and  political commitment to solving
estuarine problems.
    If an estuary meets the NEP
guidelines, the EPA Administrator
convenes a management confer-
ence of representatives from  inter-
ested Federal, Regional, State, and
local governments; affected indus-
tries; scientific and academic  institu-
tions; and citizen organizations! The
management conference defines
program goals and objectives, iden-
tifies problems, and designs strate-
gies  to prevent and control pollu-
tion  and manage natural resources
in the estuarine basin. Each man-
agement conference develops and
initiates implementation of a
Comprehensive Conservation and
Management Plan (CCMP) to
restore and protect its estuary.
    With the addition of seven estu-
ary programs in July 1995, the NEP
currently supports 28 estuary
projects (Figure 12-14):

• Puget Sound in Washington State
• Columbia River in Oregon and
  Washington
• Tillamook Bay in Oregon
•, San Francisco Bay Estuary  in
  California
• Morro Bay in California

  cut and New York
• Peconic Bay in New York
• Narragansett Bay in Rhode Island
• Buzzards Bay in Massachusetts
• Massachusetts Bay in Massachu-
  setts
• New  Hampshire Estuaries in New
  Hampshire
• Casco Bay  in Maine.

    These 28  estuaries are nationally
significant in their economic value
as well as in their ability to support
living resources. The project sites
also represent a broad range of
environmental conditions in
estuaries throughout the United
States and its  Territories.
    The NEP integrates science and
decisionmaking for the protection,
restoration, and maintenance of
estuaries. Through a characterization
process, scientists from Federal,
State, and local government agen-
cies, academic institutions, and the
private sector analyze an estuary's
problems and their causes and work
with estuary managers to suggest
remedies. Because the NEP is not a
research program, it relies heavily
on past and current research of
other agencies and institutions to
support its work.
    Appendix C, Table C-10, lists
physical and economic characteris-
tics of the NEP estuarine basins. The
table also describes each estuary's
susceptibility to pollution  in terms  of
its ability to flush out and dilute
pollutants. This information  is being
evaluated as part of a national
survey of nutrient enrichment in
estuaries, sponsored jointly by EPA
and  NOAA.

Estuarine Problems

    Each of the 28 estuaries in the
NEP is unique, yet the estuaries
share common  threats and stressors.
Each estuary faces expanding
human activity near its shores that

                                     lawns and agricultural lands, faulty
                                     septic tanks,  and even ground water
                                     discharges. (For example, nitrates
                                     are believed to leach  into ground
                                     water and discharge into the Dela-

                                     ria respond to elevated inputs of

                                     the Sound. During recent summers,
                                     poor water circulation exacerbated
                                     hypoxia problems in parts of the
                                     Sound. The Long Island Sound

                                     the Sound and concluded that dis-

                                     loadings to the estuary.
•  The Delaware Inland Bays Man-
agement Conference is focusing on
the Inland Bays' capacity to assimi-
late nutrients. First, the study identi-
fied critical information gaps and
planned research projects to fill the
gaps. Ongoing research projects
target four goals: (1) determine
ground water contributions of nutri-
ents, (2) develop a mass balance
model of nutrient cycling between
ground water and the Inland Bays,
(3) define nutrient transport pro-
cesses in the Inland  Bays' basin, and
(4) develop a strategy for using
living resources as indicators of
water quality. The project coordi-
nates public input and research
conducted by Federal, State, aca-
demic, and private scientists in an
attempt to characterize the estuary
and develop a Comprehensive  Con-
servation and Management Plan.

Toxic Substances

•  Metals in Massachusetts Bay illus-
trate the  impact from sewage treat-
ment plants, atmospheric
deposition, and polluted tributaries.
The Bay receives high metal loading
from the Merrimack River. The
Comprehensive Conservation and
Management Plan for the Bay will
have to address sources of metals
contaminating the Merrimack River
as well as sources discharging
metals directly into the Bay.

•  Sediment core samples collected
at Narragansett Bay revealed that "
most metal concentrations peaked
during the 1950s and have declined
by an average of 60% since the
1950s. The study attributes declines
in metal concentrations to improve-
ments in sewage treatment.

•  The Casco Bay Estuary Project
focuses on the extent of toxic con-
tamination in Bay sediments. Heavy
metal concentrations in Casco Bay
sediments exceed concentrations in
most NEP estuaries. The Casco Bay
study detected heavy metals, PCBs,
PAHs, pesticides, dioxins, and other
organic compounds in the Casco
Bay sediments. NOAA's flounder
liver survey revealed heavy
concentrations of lead, copper, zinc,
silver, and PCBs in fish captured in
Casco  Bay.

Pathogens

    Pathogens are bacteria and
viruses that cause diseases. To pro-
tect  public health, State agencies
prohibit the harvest of shellfish in
waters contaminated with patho-
gens or pathogen indicators, such
as fecal coliforms. Waters contami-
nated with pathogens also pose a
health risk to swimmers, surfers, and
divers.

•  A growing network of shellfish
farms on the Indian River Lagoon
serves  as a monitoring system to
alert scientists and managers to
water quality problems in the
Lagoon, including the presence of
pathogens.

•  Elevated counts of bacterial and
viral indicators in two Santa  Monica
storm drains raised concern  about
the safety of swimming near storm
drain outfalls. Additional sampling
confirmed elevated bacterial indica-
tor counts in the surf zone and in
storm drain  runoff. However, the
data were inadequate to calculate
health risks.  The study recom-
mended additional research  to
determine the source of fecal organ-
isms and viruses in the storm drains
and the dispersion of runoff along
the shoreline.

Living Resources
and Their Habitat

    Overharvesting and loss of
habitats have led to a decline of
valuable species, an increase in
populations of less desirable species,
and a decrease in the diversity of
living resources in estuaries. Land
development in  upland areas in-
creases sedimentation in waterways;
construction in wetlands destroys
this valuable filter system and habi-
tat for juvenile fish; bulkheading
interferes with natural plant and
animal shoreline interactions; and
dredge  and fill activities create tur-
bid waters, destroy habitat, and
interfere with circulation patterns. In
Florida,  ongoing estuary projects
study the effects of habitat changes,
rapid growth and development, and
sewage treatment plant expansion
on living resources.

•  The Florida Marine Research Insti-
tute is conducting  cooperative stud-
ies of fish-habitat relationships in
Tampa  Bay with NOAA funding
channeled  through the Florida
Department of Environmental Regu-
lation. These studies  examine fish
community structure along the
salinity gradient, fish density in
seagrass beds and  unvegetated
habitats, and the use of micro-
habitats by economically valuable
fish species. The State will enter the
results of this research  into a data-
base for predicting the effects of
future habitat modifications.

                                     expanded our understanding of
                                     estuarine problems, cooperative
scientific studies must continue to
evaluate management options for
correcting estuarine impairments.
Knowledge of estuarine systems lays
the foundation for successful
management plans.

Looking to the Future:
Trends and Needs

Closer Integration with
EPA Programs

    There is growing concern about
impacts on estuaries from air depo-
sition, solid and hazardous waste
sites, and contaminated ground
water. Several NEP projects are
investigating cross-media pollutant
sources. The Long Island Sound
Study is investigating the role that
vehicle emissions play in polluting
the Sound. Work at Superfund  sites
in Puget Sound and Buzzards Bay
has been coordinated with NEP
projects, but even closer ties
between remediation activities at
waste sites and estuary projects are
needed. Although the New York-
New Jersey Harbor estuarine pro-
gram addresses the problems
caused by solid waste, few projects
deal directly with trash by encour-
aging household recycling  and
waste reduction. With cooperation
from the Rhode Island business
community, the Narragansett Bay
Project is performing hazardous
waste audits and encouraging
source reduction, recycling, and
safer chemical substitution.
    Though much interaction
among EPA's  base programs  is
under way, more integration is
needed  at EPA Regional Offices and
Headquarters.

A Scientific/Management/
Public Partnership

    Using the scientific knowledge
gathered and interpreted during the
characterization phase ensures that
the public, elected officials, and
special interest groups-all part of
the Management Conference-
understand the problems of the
estuary and are prepared to support
the measures needed to correct the
problems.
    This process is simple in theory
but complex in practice. Scientists
do not always agree on the causes
of a problem or the solutions. Fur-
thermore, scientists and managers
do not always communicate well
with each other. In the NEP, man-
agers operate on a 5-year plan; yet
scientists rarely operate on a fixed
5-year plan. Under the auspices of
the Management Conferences,
however, scientists are focusing their
research and applying their results
to project managers' needs and
time constraints. Managers are chal-
lenging scientists to direct their
studies .to meet Management Con-
ference needs for short-term
answers. The Management Confer-
ence enhances communication
between scientists and managers
and results in better solutions to
management issues.
    Members of the public often
express concerns about highly vis-
ible problems, yet these issues may
not be the most important prob-
lems for the Management Confer-
ence to consider. In fact, spending
resources on a highly visible but
relatively insignificant problem could
divert attention from a crucial mat-
ter. It is imperative, therefore, that
scientific findings be widely
communicated and form the basis
for public education efforts.

•  'Faced with diverse constituencies,
each with a different idea of what
constitutes  a monitoring program
appropriate for Santa Monica Bay,
the Santa Monica Bay Restoration
Program held a 2-day consensus-
building conference for scientists,
managers, dischargers, regulators,
and public  interest group
representatives. The conference goal
was to outline monitoring objectives
that would guide the development
of detailed  hypotheses and sam-
pling and analysis plans. Conference
participants were led through a set
of structured exercises that focused
on the overall concerns driving the
regulatory/monitoring system,
agreement on a  monitoring philoso-
phy for the Bay,  and determination
of which Bay resources were the
most highly valued.  These exercises
were followed by a decisionmaking
process through  which specific
monitoring objectives were devel-
oped. The selected objectives
reflected management goals,
scientific knowledge, and public
concerns.
    Every estuary program in the
NEP has a public participation and
education component. Solutions to
pollution problems are grounded in
scientific information, but protection
of habitats  and commitment to
action are dependent upon public
education. Through  education and
participation, the public gains an
understanding of the estuary and its
problems, the will to act to solve
immediate  problems, and the desire
to be stewards of the ecosystem for
the future.

                                     Priority Concerns

                                        The public, in partnership with
                                     scientists and government manag-
                                     ers, faces enormous challenges com-
                                     pounded by the population growth
                                     projected to continue in the coastal
                                     zone well into the 21 st century. We
                                     will need to manage this growth
                                     more effectively to protect our
                                     coastal resources. Critical manage-
                                     ment areas that must be addressed
                                     include general growth and
                                     development,  nonpoint sources,
                                     and natural habitat destruction.

                                     Growth and Development

                                        Coastal population growth and
                                     development patterns disrupt natu-
                                     ral processes in coastal ecosystems
                                     and threaten both the ecologic and
                                     economic values of estuaries. As we
                                     approach the year 2000, we must
                                     improve conventional pollution con-
                                     trols and accelerate enforcement
                                     actions. However, new strategies are
                                     required to solve the more complex
                                     problems brought about by increas-
                                     ing pressure to develop rural areas
                                     and sensitive pristine areas.
                                        Shoreline development often
                                     strips vegetation and eliminates
                                     wetlands, which exposes the land to
                                     erosion. Increased sedimentation in
                                     shallow waters chokes underwater
                                     grasses and threatens fish and shell-
                                     fish habitats. Development near
                                     shorelines also damages life-sustain-
                                     ing habitats for shore birds and
                                     animals.
                                        As development replaces veg-
                                     etation with less pervious surfaces
                                     (such as buildings, parking lots, and
                                     roads), rainwater cannot seep slowly
                                     into the soil and replenish ground
                                     water. Instead, storm water runs off
the impervious surfaces, collecting
pollutants deposited from the air,
and delivers the pollutants directly
into surface waters. Without wet-
lands and other vegetated areas, the
land cannot filter pollutants from
storm water runoff before it enters
estuarine waters. Looking  ahead,
our major challenge is controlling
nonpoint sources resulting from
population growth and their
impacts on estuarine habitats.

Nonpoint Source Control

    Section 319 of the Clean Water
Act provides funding for some
nonpoint source control projects in
estuarine waters (see Chapter 11 for
a full discussion of the Section  319
Nonpoint Source Program).  States
employ both voluntary and regula-
tory controls to encourage imple-
mentation of best management
practices to minimize nonpoint
source pollution generated by agri-
culture, construction, silviculture,
marinas, and urbanization.
    The 1990 amendments to the
Coastal Zone Management Act
(CZMA) require States with federally
approved coastal zone management
programs to develop nonpoint
source pollution control programs in
coastal areas. Each State's program
will consist of selected management
measures for source  categories, such
as construction, marinas, and agri-
culture. The States will develop and
implement the coastal nonpoint
source programs through  existing
State coastal zone management
programs administered by NOAA
under Section 306 of the CZMA
and State nonpoint source pro-
grams administered  by EPA under
Section 319 of the Clean Water Act.

Pollution in Coastal Waters and

Habitat Protection

    NEP projects are looking
beyond traditional pollution control
approaches toward strategies that
address total estuarine ecosystem
health. These strategies base habitat
protection plans on  a scientific
understanding of  how ecosystems
function. These long-term strategies
require further coordination of
research and monitoring activities
performed by EPA, NOAA,  individual
NEP projects, marine academic insti-
tutions, and  other Federal and State
agencies.
    While long-term strategies are
being developed,  management
conferences act locally to address
immediate threats to estuarine habi-
tats. For example, management
conferences limit fish harvesting,
replant seagrass beds,  seek building
restrictions such as setback require-
ments, create land conservation
areas, and curb harmful uses of
waterways. Such efforts are not
implemented in all NEP sites but will
likely be more widespread in the
future.
    Management conferences will
need to work even more closely
with agencies such as the U.S. Fish
and Wildlife Service  and the U.S.
Army Corps of Engineers to improve
our understanding of habitat prob-
lems and develop new technologies
to mitigate adverse impacts. Ex-
amples of new technologies include
stabilizing shorelines with vegetation
instead of bulkheads and techniques
for creating wetlands. EPA is work-
ing with Management Conferences
to increase habitat mitigation activi-
ties, such as removing dams
blocking fish migrations  and elimi-
nating freshwater diversions.

Steps in the Right Direction

    The NEP recognizes  that it may
take decades to fulfill Congress'
directive to restore and protect estu-
aries of national significance.  In the
short term, however, progress con-
tinues. Each estuary project in the
NEP is focusing on the key environ-
mental problems in its estuary and
integrating protection efforts con-
ducted by Federal, State, and local
agencies. NEP projects are consider-
ing air and land pollution sources in
addition to controls for traditional
point source polluters. Finally, NEP
projects are developing restoration
and protection strategies based
upon  an understanding of estuarine
ecosystem functions and encourag-
ing the public to care for estuarine
ecosystems.

                                     (Figure 12-15). The main objective
                                     of this assessment is to provide a
                                     biennial report to Congress on the

                                     the Great Waters. The essential goal
                                     of the Great Waters Program is to
                                     evaluate whether the problem of
                                     atmospheric deposition to these
                                     aquatic ecosystems is a significant

human health and the environment.
    Specifically, Section 112(m)
requires that EPA establish deposi-
tion monitoring networks in the
Great Waters, as well as conduct
additional study, such as assessing
sources and deposition rates, evalu-
ating  adverse effects, research on
monitoring methods, and biotic
sampling. The reports to Congress
address three main issues: (1) the
contribution of atmospheric deposi-
tion to total pollutant loading to the
Great Waters; (2) the adverse effects
on human health and the environ-
ment; and (3) sources of the pollut-
ants. In addition, EPA must deter-
mine  whether the other  regulatory
programs under Section  112 are
"adequate to prevent serious
adverse effects to public  health and
serious or widespread environmental
effects, including those effects
resulting  from indirect exposure
pathways." EPA must then promul-
gate such changes under Section
112 that may be necessary to pre-
vent adverse effects  and  make rec-
ommendations regarding any regu-
latory changes under any other
applicable Federal legislation neces-
sary to ensure protection of human
health and the environment.

Progress Under
Section 112(m)

    EPA has made progress  imple-
menting  the specific monitoring
requirements of Section 112(m). In'
1992, EPA established five master
(regional background) stations to
collect wet and dry toxics deposi-
tion samples at each of the Great
Lakes  as part of the  Integrated
Atmospheric Deposition  Network, a
joint effort between  the United
States and Canada. EPA and the

-------
                         Chapter Twelve The Watershed Protection Approach and Place-based Management Programs   351
 Chesapeake Bay States began col-
 lecting toxics samples at three
 stations on the Bay in 1990. EPA is
 also involved in mercury deposition
 monitoring on  Lake Champlain and
 interacts with a State-run toxics
 deposition program for the Lake.
    EPA has implemented many
 other activities  to expand our
 understanding  of atmospheric
 deposition of HAPs and related risks
 to human health  and the environ-
 ment:

 • Conducted an  extensive literature
 review and supported the develop-
 ment of three background docu-
 ments leading up to preparation
 and release of the first Great Waters
 Program Report to Congress in May
 1994

 • Assessed the 1990 Amendments'
 list of 189 HAPs to determine which
 HAPs are most  likely to be problem-
 atic when deposited in aquatic sys-
 tems

 • Preparing a national screening
 level emission inventory for specific
 pollutants in Section 112(c)(6), as
 well as assisting the Great Lakes
 States in developing a comprehen-

The Great Waters Report
to Congress

    In May of 1994, EPA's Office of
Air Quality Planning and Standards
submitted the first Great Waters

                                     Great Waters. This first Report to
                                     Congress summarizes the current
                                     understanding of atmospheric depo-
                                     sition of toxic chemicals to the
                                     Great Waters and identifies key
                                     regulatory and research needs.
                                         EPA and  NOAA relied heavily on
                                     participation  by independent scien-
                                     tists to help prepare Deposition of Air
                                     Pollutants to the Great Waters. As a
                                     first step, EPA sponsored a literature
                                     search on the topic of atmospheric
                                     deposition of chemicals to surface
                                     waters, identifying more than 1,100
                                     scientific publications. EPA then
                                     convened three committees of lead-
                                     ing independent scientists and
                                     charged them with evaluating and
                                     summarizing the literature in the
                                     three areas identified in Section

                                         Each committee prepared a
                                     draft paper that was the topic of
                                     discussion at a workshop sponsored
                                     by EPA in the fall of 1 992. Attend-
                                     ees of the workshop included com-
                                     mittee members, other independent
                                     scientists, EPA scientists, EPA pro-
                                     gram representatives, and represen-
                                     tatives from groups such as NOAA,
                                      State agencies, industry, and  envi-
                                      ronmental groups. Following  the
                                     workshop, the committees prepared
                                     final  background documents  that
                                      became the foundation for the
Report to Congress. The contents of
the Report to Congress are summa-
rized below.

Exposure and Effects of
Atmospheric Deposition

    Over the past three decades,
scientists have collected a large and
convincing body of evidence show-
ing that toxic chemicals released to
air can travel long distances and be
deposited on land or water at loca-
tions far from their original sources.
Perhaps most notably, it appears
that PCBs and some other pollut-
ants that are persistent in the envi-
ronment (including several pesti-
cides that have not been used in
significant amounts in the United
States since the 1970s) have
become widely distributed in the
environment. These toxic chemicals
remain in our environment and
continue to cycle between air,
water, soil, and biota (living  organ-
isms) even after their manufacture,
use, or release has stopped. Their
persistence increases the potential
for exposure to these toxic chemi-
cals.
    Pollutants of concern (see
sidebar) also accumulate in body
tissues and magnify up the food
web, with each level accumulating
the toxics from its diet and passing
the burden along to the animal in
the next level of the food web. Top
consumers in the food web, usually
consumers of large fish, may accu-
 mulate chemical concentrations
 many millions of times greater than
the concentrations present in the
water. Fish consumption advisories
 have been issued in hundreds of
waterbodies nationwide, including
 the Great Lakes, as a result of unsafe
 concentrations of chemicals in fish

-------
                          Chapter Twelve The Watershed Protection Approach and Place-based Management Programs   353
 due to biomagnification (see Chap-
 ter 7 for more information about
 fish consumption advisories).
     Significant adverse effects on
 human health and wildlife have
 been observed due to exposure
 (especially through fish consump-
 tion) to persistent pollutants that
 bioaccumulate. Adverse effects
 range from immune system disease
 and reproductive problems in wild-
 life to subtle developmental and
 neurological impacts on children
 and fetuses. Although most of the
chemicals of concern are probable
human carcinogens, many are also
developmental toxicants capable of
altering the formation and function
of critical body systems and organs.
Therefore, developing embryos,
fetuses, and breast-fed infants are
particularly sensitive to these chemi-
cals through exposure of the
mother.
    Ecological effects attributable to
pollutants of concern are significant
and can be  subtle or delayed  in
onset,  such  as immune function

                                     or neurological changes—all of
                                     which can affect population sur-
                                     vival. Other adverse ecological ef-
                                     fects are caused by nitrogen com-
                                     pounds. Atmospheric sources of
                                     nitrogen exacerbate nutrient enrich-
                                     ment (or eutrophication) of coastal
                                     waterbodies, which results in
                                     impacts that range from nuisance
                                     algal blooms to the depletion of
                                     oxygen and resultant fish kills.

                                          Studies show that significant
                                     portions of loadings to the Great
                                     Waters  of the  pollutants of concern
                                     are coming from  the atmosphere.
                                     For example, 76% to 89% of the
                                     loadings of PCBs to Lake Superior
                                     and up to 40% of the  loadings of
                                     nitrogen into the Chesapeake Bay
                                     are estimated  to come from air
                                     pollution. However, insufficient data
                                     are available to quantify the overall
                                     relative atmospheric loadings for all
                                     of the HAPs entering all of the
                                     Great Waters. Therefore, relative
                                     loadings estimates are, and will
                                     continue to be, chemical-specific
                                     and waterbody-specific. The abso-
                                     lute quantity of atmospheric load-
                                     ings also warrants attention because
                                     even small loadings of pollutants
                                     that bioaccumulate can result in
                                     significant pollutant burdens in fish
                                     and, ultimately, in humans.

                                     Sources of Atmospheric
                                      Pollutant Loadings

                                          Pollutants of  concern in the
                                     Great Waters originate from both
                                      local and distant  sources. Many
                                     sources of atmospheric pollutants
that enter the Great Waters have
been identified, including waste
incinerators at industrial and munici-
pal facilities, power plants, petro-
leum refineries,  motor vehicles, vari-
ous manufacturing processes, and
residential combustion of fossil  fuels.
However,  determining the particular
sources responsible for deposited
pollutants is quite difficult because a
combination of sources generate the
atmospheric loadings entering  any
particular  waterbody, and transport
distances vary depending on the
characteristics of the chemicals,
emissions, and weather conditions.
Additional data are needed to iden-
tify and characterize the specific
sources responsible for pollutants
that are deposited to the Great
Waters.

Recommendations and
Actions

    EPA considered the implications
of action and inaction, while also
recognizing that Section  112(m)
mandates that EPA should act to
"prevent" adverse effects and to
"assure protection of human health
and the environment."  EPA recom-
mends that reasonable actions are
justified by the available scientific
information and should be imple-
mented now while research contin-
ues. Although there are significant
uncertainties in the available infor-
mation, there is enough convincing
evidence to prompt action. Adverse
effects of  the chemicals of concern
are evident and studies of selected
waters show that significant propor-
tions of toxic pollution come from
the atmosphere. EPA believes that
the characteristics of toxicity, persis-
tence, and tendency to bioaccumu-
late warrant special treatment  of the

-------
                         Chapter Twelve The Watershed Protection Approach and Place-based Management Programs   355
Great Waters pollutants of concern.
However, the actions recommended
by EPA focus on chemicals of con-
cern rather than specific sources
because the linkage between spe-
cific sources and subsequent deposi-
tion and effects has yet to be dem-
onstrated. NOAA concurs with  the
principles of this policy.
    EPA's recommendations for
action fall into three strategic
themes. First, EPA will continue
ongoing efforts to implement Sec-
tion 112 and other sections of  the
Clean Air Act and use the results of
the Report to Congress in the devel-
opment of policy that will reduce
emissions of Great Waters pollutants
of concern. Under this theme, EPA
will take actions that include:  pub-
lishing emission standards affecting
important chemicals of concern
ahead of schedule, where possible;
evaluating the adequacy of control
technologies for important pollut-
ants; publishing an advance notice
of proposed rulemaking (ANPR) for
establishment of lesser-quantity
emission rates (LQERs) to define
smaller sources to be regulated as
major sources and evaluating which
Great Waters pollutants warrant
establishment of an  LQER; evaluat-
ing which area sources should be
regulated with maximum achievable
control technology (MACT); and
considering appropriate emission
levels  requiring  regulation when
sources are modified.
    Second, EPA recognizes the
need for an integrated multimedia
approach to the problems of the
Great Waters and, therefore, will
utilize authorities beyond the Clean
Air Act to reduce human and envi-
ronmental exposure to pollutants of
concern.  Under this  theme, EPA will
take actions that include using the
Great Waters Core Project Manage-
ment Group as a coordinating body
to communicate with other offices
and agencies. The objectives will be
to coordinate work and especially to
identify lead offices to implement
recommendations; support changes
to the Clean Water Act that address
nonwaterborne sources of water
pollution; address the exportation of
banned pesticides; emphasize pollu-
tion prevention efforts to  reduce
environmental loadings of pollutants
of concern; and facilitate informa-
tion sharing between EPA and other
agencies.
    Third, EPA will continue to
support research activities and will
develop and implement a program
strategy to define further necessary
research. Under this theme, EPA will
take actions that include focusing
research planning  on a mass-
balance approach  to determine
relative loadings; using an appropri-
ate mix of monitoring, modeling,
and emission inventory tasks in con-
ducting mass-balance work; assess-
ing the need for tools to be devel-  -
oped for risk assessment for total
exposure to pollutants of concern
and for regulatory benefits assess-
ment; and continuing to support
ongoing research efforts.

                                                   You may notice that this highlight is a little different from the rest of this
                                               report. It covers an entire river basin rather than a single State, it summarizes
                                               information on use support by hydrologic unit, and the style and format are
                                               (hopefully) easier for general audiences to understand.

                                               water quality monitoring nationwide. The chapter also incorporates similar sug-
                                               gestions from an EPA  working group. If these changes are well received, we will
                                               incorporate them more extensively in the next National Water Quality Inventory
                                               and in other related publications.
    From trout streams in the moun-
tains of western Pennsylvania to
industrial ports along the Ohio and
Tennessee Rivers, waters of the Ohio
River and Tennessee River basin play a
vital role in the economy and quality of
life in a part of the United States
roughly the size of France. Covering
parts of 14 States, the Ohio and Ten-
nessee River basin provides a place to
live and work for over 26 million
people.

Water Uses

    Pittsburgh, Cincinnati, Louisville,
Columbus, Indianapolis,  Chattanooga,
Nashville,  and hundreds of other towns
depend on the basin's rivers to provide
water for their residents and industries.
Shippers rely on the nearly 2,600 miles
of navigable waterways for reliable,
cost-effective transportation of raw
materials and other commodities.
    Power plants in the Ohio and Ten-
nessee River basin produce about 10%
of the Nation's electricity and are
strategically located along waterways so
they will have adequate supplies of
cooling water for operation. Farmers
irrigate their crops with water from
these streams and lakes to help feed
their families and the Nation.
   Boaters, skiers, swimmers, anglers,
kayakers, and other water sports
enthusiasts use the basin's many lakes
and streams to satisfy their recreational
interests, pumping millions of dollars
into local economies. And the thou-
sands of species of fish, mussels, insects,
birds, and other wildlife that spend at
least part of their lives in the basin's
lakes and streams are the food web that
supports recreational and commercial
fishing, waterfowl  hunting, and many
other commercial enterprises.

Water Use Designation
and  Criteria

   To help ensure that the Ohio and
Tennessee River basin's waters are clean
enough to support these varied uses,
each State specifies the uses each  of the

waters in its borders should support. For
each designated use, the States and EPA
have developed a set of water quality
criteria that the waterbodies must meet.
    These criteria include limits on
chemical contaminants, and many
States now include standards for the
integrity of aquatic biological communi-
ties, particularly for those waters classi-
fied for supporting aquatic life uses.

How Clean Are the Waters
of the Ohio River and
Tennessee River Basin?

Good News for Aquatic Life

    About 75% of the streams and river
miles surveyed in the Ohio and Tennes-
see River basin fully support aquatic life
uses, and another 15% partially support
those  uses. For 5% of the fully support-
ing category, there is some threat to
that status. Only 10% of surveyed
stream miles are judged as not support-
ing aquatic life uses, based on evalua-
tion guidelines recommended by EPA.

... And for Recreation
    For water contact recreation such
as swimming,  wading, and skiing, 78%
of surveyed miles fully support those
uses, with about 5% of that category
also threatened. For 14% of the sur-
veyed miles, water quality is not  good
enough to support contact recreation.

How About Drinking Water?
    Only about 2% of the basin's
waters were evaluated for their suitabil-
ity as sources of drinking water supplies.
Most of the surveyed reaches (78%)
fully support this use, with  that support
threatened for about 5%. For only 7%
is water quality so poor that,  based on
EPA guidelines, they do not support this
use.
What's the Big Picture
for the Ohio  River and
Tennessee River Basin?

    Although it's reassuring that most
of the streams surveyed in the Ohio and
Tennessee River basin fully support a
variety of uses, most of us want to
know  how our area compares with
others, and whether any of the problem
streams are nearby.
    Figure 1  summarizes information
on aquatic life use support for the
whole Ohio and Tennessee River basin.
Each area in the map represents land
that drains into one moderate-sized
stream or stream segment. Each area is
shaded with one of five patterns based
on the relative amount of stream miles
that fully support aquatic  life uses versus
the amount that does not support
aquatic life uses, according to EPA
guidance.

                   The map points out some
               important facts about comparing
               information across broad areas. How
               well you can evaluate use support
               throughout a large basin depends on
               the availability of enough of the right
               information and on States using compa-
               rable assessment techniques and inter-
               pretations. For example, there is a dis-
               tinct boundary along the  Ohio-Indiana
               border between relatively good condi-
               tions for aquatic life use support in
               Indiana and relatively poor conditions in
               Ohio. In reality, there probably isn't
               much difference in stream quality, but
               Ohio has much more information >avail-
               able, and  depends heavily on biological
               data to evaluate aquatic life use sup-
               port. Similar use support boundaries are

What Are the Main
Pollutants? And Where Do
They Come From?

Pollutants
    As Figure 2 illustrates, Ohio and
Tennessee River basin States report that
siltation impairs aquatic life in more
stream miles than any other pollutant.
Organic enrichment, such as inade-
quately treated wastes, runoff from
confined animal production  operations,
and some types of industrial wastes, is
the second largest category  of pollutant
impairing aquatic life uses.
    The States report that bacterial
contamination is the main reason some
streams are not suitable for swimming
and other contact recreation uses. Only
two States reported on causes of non-
support for drinking water supply uses,
citing pesticides and other toxic organic
chemicals as the  main problem.
    The most common contaminants
that cause Sates to issue advisories
about limiting or avoiding consumption
of certain fish are PCBs, chlordane, and
mercury.

Sources
    Mining and other types of resource
extraction, including petroleum extrac-
tion and processing, are the most com-
mon source of pollutants in  the Ohio
and Tennessee River basin (see Figure
3). Without proper controls, these types
of activities are sources of siltation,
acidity, and metals contamination of
streams.
    Agricultural sources are the second
largest source category, contributing
silt, nutrients, bacteria, and organic
enrichment to streams. Within this
category, cropland and  pastureland are

Where Did the Data Come From?
How Complete Are They?
The information in this chapter is based on assessments
reported by j
the 14 Ohio River and Tennessee River basin States. Of the basin's 255,000 i
miles of streams, they
collectively reported on 83,000 miles (33%) for
aquatic life use support, 44,000 miles (17%) for contact recreation, and <
6,200 miles (2%) for drinking water. No information on lakes, wetlands, or ".,
ground water is included in this highlight, simply because it wasn't practi- ~- i
cal to try to evaluate that information for the whole Ohio and Tennessee
River basin with the time and resources available. i

that our Nation's water pollution con-
trol programs are working. Most of the
region's streams are suitable for people
to use for fishing, swimming, and
obtaining water to be treated and
distributed to their homes.
In addition, the basin's streams and
rivers support a productive economy,
providing habitat for fish, cooling and
process waters for industries, navigation
for raw materials, and a place for the
public to recreate.
Perhaps the second most important
message is that the work of protecting
and improving water quality is never
done, and it is everyone's business. As
control of wastewater discharges
improves, runoff from city streets, home
lawns, pastures and croplands, and
other land disturbances become a
bigger part of the equation.
But these "nonpoint" sources are
much more difficult to control. Effective
reduction of pollution from these
sources requires individuals to accept

Water Monitoring
and  Assessment Programs
Introduction
   Water quality monitoring is
essential for an understanding of
the condition of water resources
and to provide a basis for effective
policies that promote wise use and
management of those resources.
A large number of Federal, Tribal,
State, and local agencies and pri-
vate sector organizations currently
collect water quality information for
a wide range of purposes that can
generally be  divided into five
categories: (1) status and trends,
(2) detection of existing and emerg-
ing problems and setting priorities
among them, (3) designing and
implementing programs, (4) evalu-
ating program or project success,
and (5) emergency response moni- .
toring.
    Numerous public and private
groups conduct many and varied
monitoring programs to fulfill one
or more of these purposes. This
chapter discusses current conditions
of water resource quality monitor-
ing in the United States and efforts
to establish an integrated nation-
wide monitoring strategy.

Overview of National
Monitoring Activity

   Water resource quality monitor-
ing is conducted by Federal,
interstate, State, local, and Tribal
agencies, as well as public, private,
and volunteer organizations. A
recent study undertaken by the
Intergovernmental Task Force on
Monitoring Water Quality indicates
that 18 Federal agencies conduct
approximately 141 separate moni-
toring programs across the country,
as do all States and Territories, local
governments,  and an increasing
number of American Indian Tribes.
   At the Federal level, ambient
water quality data are collected by
the U.S. Geological Survey, the U.S.
Fish and Wildlife Service, the U.S.
Forest Service, the Bureau of Recla-
mation, the National Park Service,
EPA, National  Oceanic and Atmos-
pheric Administration, the Tennes-
see Valley Authority, the Bonneville
Power Administration, the U.S.
Army Corps of Engineers, the
Bureau of Land Management (BLM),
and various other organizations
within the Departments of Agricul-
ture (USDA), Energy, Defense
(DOE), and Interior. Of this group,
the USGS, FWS, EPA, NOAA, and
TVA have either long-term regional
or both regional and national pro-
grams for water quality monitoring.
The other agencies and organiza-
tions monitor ambient water qual-
ity primarily at site-specific or
project scales, usually for limited
periods of time.
    Results from Federal monitoring
programs have provided important
information at the national and
 In addition to monitor-
   ing performed by
   States, Tribes, and
       Territories,

18 FEDERAL
  AGENCIES
conduct 141 monitoring
  programs across the

                                   regional scales. For example, USGS
                                   data indicate that fecal bacteria
                                   counts and total phosphorus
                                   concentrations have decreased at a
                                   considerable number of stations
                                   across the United States from the
                                   late 1970s to the late  1980s. The
                                   FWS and NOAA data show that
                                   bioaccumulation of trace elements,
                                   pesticides, and trace industrial com-
                                   pounds has occurred at many loca-
                                   tions in our rivers,  estuaries, and
                                   near-coastal areas. And data from
                                   EPA monitoring indicate substantial
                                   improvement in the phosphorous
                                   concentrations of the Chesapeake
                                   Bay during the past 6 years.
                                       Similarly, within each State,
                                   both State and local monitoring
                                   programs have provided the data to
                                   characterize State water resource
                                   quality and assess the  effectiveness
                                   of water management and regula-
                                   tory programs. A growing number
                                   of Tribes are also monitoring their
                                   water resources. Contributing to the
                                   picture are the monitoring pro-
                                   grams run by industrial and munici-
                                   pal dischargers, by private groups,
                                   and by volunteer monitoring organi-
                                   zations.
                                      This wealth of information from
                                   individual agencies, however, can-
                                   not be easily aggregated to provide
                                   an overview of national water qual-
                                   ity conditions because of inconsis-
                                   tencies among the various agencies
                                   in monitoring purpose and design
                                   as well as data collection methods
                                   and assessment procedures. In addi-
                                   tion, data are often stored without
                                   accompanying descriptors, thus
                                   other data users cannot determine if
                                   they can use the data for their own
                                   purposes.
Effects  of  Changes
in Water Programs

    In addition to this multiplicity of
effort, water programs themselves
are changing, necessitating similar
changes in water monitoring activi-
ties. The country is moving beyond
single-media command-and-control
programs into more holistic man-
agement programs based on risk
assessment and reduction. New
emphases include watershed,
ecoregion, and geographically
based programs; a focus on biologi-
cal, ecological, and habitat integrity
and diversity;  wet weather runoff
control programs such as those for
nonpoint sources, stormwater, and
combined sewer overflows; and
wetlands and  sediment contamina-
tion programs. Traditional monitor-
ing programs  must be expanded to
include assessment of biological and
ecological resources and new meth-
ods must be developed to identify
and control pollution from hard-to-
trace, diffuse  sources of pollution
such as wet weather runoff and
sediment contamination.

Intergovernmental
Task Force on
Monitoring Water
Quality

    In January of 1992, representa-
tives from EPA, USGS, NOAA, FWS,
COE, USDA, DOE, Office of Man-
agement and  Budget (OMB), and
seven State agencies and  one
interstate agency formed a 3-year

                                                  Chapter Thirteen  Water Monitoring and Assessment Programs   363
Intergovernmental Task Force on
Monitoring Water Quality (ITFM) to
prepare a strategy for improving
water quality monitoring nation-
wide. The Tennessee Valley Author-
ity, National Park Service, one State,
and one American Indian Tribe,
have since been added. The  ITFM is
part of the implementation of OMB
memorandum 92-01 to strengthen
coordination of water information
across the country. The USGS has
lead responsibility for this under its
Water Information Coordination
Program.
    The ITFM is chaired by the U.S.
EPA with the USGS as vice chair and
Executive Secretariat. To date, over
100 additional Federal, State, and
interstate agency representatives
have been involved  in the delibera-
tions of the ITFM and its six task
groups:

    •  Institutional Framework

    •  Environmental Indicators

    •  Methods

    •  Data  Management Sharing

    • Assessment and Reporting

    •  Ground Water.

    The ITFM is considering the
full range of nationwide water
resources, including surface and
ground waters, near-coastal waters,
associated aquatic communities and
habitat, wetlands, and sediment.
Water resource protection factors
include human and  ecological
health and the uses designated for
the Nation's waters  through  State
and Tribal water quality standards.
Monitoring activities include
gathering data on physical, chemi-
cal/toxicological, and biological/
ecological/habitat parameters.
    The mission of the ITFM  is to
develop and implement a national
strategic plan to achieve effective
collection, interpretation, and pre-.
sentation of water quality data and
to improve the availability of exist-
ing information for dedsionmaking
at all levels of government. To
accomplish this, the ITFM has
recommended and will facilitate
implementation of an integrated
nationwide voluntary strategy that
will meet the nationwide objectives
of various monitoring programs,
make more efficient use of available
resources, distribute information
more effectively, and provide com-
parable data and consistent report-
ing of water quality status and

    A permanent National Monitor-
ing Council will provide guidelines
and support for comparable field
and laboratory methods, quality
assurance/quality control, environ-
mental indicators, data manage-
ment and sharing,  ancillary data,
interpretation techniques, and train-
ing. Regional data collection  under
the national guidelines would pro-
vide the needed information  for
nationwide assessment of water
resource quality.
    The ITFM and its successor, the
National Monitoring Council, are
also producing products that can be
used by monitoring programs
nationwide, such as an outline for a
recommended monitoring program,
environmental indicator selection
criteria, and a matrix of indicators to
support assessment of State and
Tribal designated uses.

                                     Assessment Program (EMAP)

                                     EPA's Office of Research and Devel-
                                     opment initiated EMAP in 1990 to
                                     provide information on the current
                                     status and long-term trends in the
                                     condition of the ecological resources
                                     of the United  States. EMAP develops
                                     indicators to measure ecological
                                     condition, monitors for those indica-
                                     tors, and presents analyses of data
                                     in periodic reports. Site selection is
                                     based on a random design within
                                     natural  resource areas so individual
                                     results can be interpolated with
                                     confidence to the condition of the
                                     Nation as a whole. EMAP, in coop-
                                     eration with NOAA and the FWS,
                                     monitors seven resource groups:
                                     Near Coastal Waters, Surface
                                     Waters, Wetlands, Forests, Arid
                                     Lands, Agroecosystems,  and Great

                                     Assessment Program  (NAPAP)

                                     During the 1970s, the effects of
                                     acid rain on the environment and
                                     human  health became a major
                                     concern for many scientists, public
                                     policy officials, public  interest
                                     groups, the media, and  the general
                                     population. Reports were published
                                     linking emissions from industry,
                                     electric  power plants,  and automo-
                                     biles with acid rain. Many believed
                                     that acid rain  damages crops,
                                     forests, buildings, animals, fish, and
                                     human  health. Congress established
                                     NAPAP under the Acid Precipitation
                                     Act of 1980 to provide the informa-
                                     tion needed for policy and
regulatory decisions on acidic
deposition. The areas of investiga-
tion addressed by NAPAP Task
Groups are Emissions and Controls,
Atmospheric Processes, Atmospheric
Transport and Modeling, Atmos-
pheric Deposition and Air Quality
Monitoring, Terrestrial Effects,
Aquatic Effects,  and Effects on Mate-
rials and  Cultural Resources. NAPAP
has also developed Assessment
Work Groups in the areas of Atmo-
spheric Visibility, Human Health
Effects, and Economic Valuation.

•  U.S. Geological Survey, National
Water Quality Assessment Program
(NAWQA)

The USGS developed NAWQA to
provide a nationally consistent
description of current water quality
conditions for a large part of the
Nation's water resources; to define
long-term trends (or lack thereof)
in water quality; and to identify,
describe,  and explain,  to the extent
possible,  the major factors that
affect observed water quality condi-
tions and trends. This program is
concerned with both ground and
surface water quality; ultimately, 60
drainage  basins will  be monitored
under this program.

•  U.S. Geological Survey, National
Stream Quality Accounting Network
(NASQAN)

This network is composed of 420
stations on large rivers, located at
the outlets of major drainage basins
to collectively measure a large frac-
tion of total runoff in the United
States. The stations reflect general
water quality conditions in the
country. Measurements at NASQAN
sites include inorganic constituents,

                                                  Chapter Thirteen Water Monitoring and Assessment Programs  365
radionuclides, and bacteria, but
exclude routine analyses for organic
chemicals.
•  U.S. Geological Survey, the Hy-
drologic Benchmark Network (HBN)

Composed of 55 stations located in
relatively pristine headwater basins,
this network is designed to define
baseline water quality conditions
and the effects of atmospheric
deposition on water quality. The
Network measures inorganic con-
stituents, radionuclides, and bacte-
rial contamination, among other
parameters.

Both NASQAN and HBN achieve
their objectives but neither is
designed to provide a statistically
representative sample of basins
throughout the Nation, nor are
stations in NASQAN purposefully
located downstream from industry,
municipal, and urban runoff outfalls
to isolate and measure maximum
impacts. These network design
considerations are a component of
the NAWQA program.


•  U.S. Geological Survey, the
National Atmospheric Deposition
Program/National Trends Network
Composed of 200 sampling sites
within the interagency NAPAP, this
network is designed to determine
spatial patterns and temporal trends
in chemical wet-only deposition. It
supports research into impacts on
aquatic and terrestrial ecosystems.
Measurements are limited to inor-
ganic constituents only.
•  U.S. Army Corps of Engineers
Water Resource Monitoring

The COE routinely monitors physical
and chemical water quality param-
eters at most of its 541 reservoir
projects. The Corps monitors to aid
in  day-to-day operational decision-
making, determine status and
trends, identify and solve problems,
evaluate project performance, and
respond to emergencies. In addi-
tion, the Corps collects and evalu-
ates water quality data for its haz-
ardous and toxic waste site cleanup
program, for special studies such  as
the Chesapeake Bay Program, and
for many other Corps mission
responsibilities. Many of these
project data sets are temporary and
spatially quite extensive, often cov-
ering much of a  project's watershed
and tailwater. There has been a
gradual trend toward increasing
biological monitoring to evaluate
project performance. All data are
maintained at local Corps offices.


•  U.S. Fish and Wildlife Service,
National Contaminant Biomoni-
toring Program (NCBP)

This program, now being revised,
determines tissue residue levels in
fish and birds nationwide. The fish
tissue part of the program consists
of 110 stations at nonrandomly
selected points along the Nation's
major rivers and  in the Great Lakes.
Fish tissues are analyzed for organic
contaminants (pesticides and indus-
trial chemicals) and seven elements.
Sampling has been conducted on a
2- to 4-year basis since the mid-
1960s.

on November 11, 1993.
•  U.S. Fish and Wildlife Service,
Biomonitoring of Environmental
Status and Trends (BEST) Program
This program, now under develop-
ment, has three major goals: (1) to
determine the status and trends of
contaminants and their effect on
natural resources; (2) to identify and
assess the major factors affecting
resources and provide current and
predictive information to alleviate
impacts; and (3) to provide sum-
mary information in a timely man-
ner to decisionmakers and the
public. The BEST Program has two
major components: FWS lands and
FWS trust species and their habitats.
Activities include  collection and
evaluation of existing data for site
characterization and bioassessment
data from four general categories-
ecological surveys, tissue residue,
organism health or biomarkers, and
toxicity tests/bioassays.

B  U.S. Fish and Wildlife Service,
National Wetlands Inventory (NWI)
Program
This program determines status and
trends of U.S. wetlands to produce
comprehensive, statistically valid
acreage estimates of the Nation's
wetlands. This information is widely
distributed and mandated by the
Emergency Wetland Resource Act of
1986. To date, more than 32,000
detailed wetlands maps have been
completed covering 72%  of the
coterminous United  States, 22% of
Alaska, and all of Hawaii and Puerto
Rico.
•  National Oceanic and Atmos-
pheric Administration, National
Status and Trends Program (NS&T)

NOAA conducts the NS&T, which
includes the Benthic Surveillance
Program and the Mussel Watch
Program. Indicators for determining
the effects on marine  biotas of con-
taminated sediments are currently
under development. Parameters that
are sampled for NS&T include accu-
mulated compounds in  the tissues
and conditions of physical features
of selected biota as well as sediment
chemistry.


•  National Oceanic and Atmos-
pheric Administration, National
Estuarine Research Reserves

The National Estuarine Research
Reserve System was created to
protect representative areas of the
estuarine environment and to
provide a system of protected sites
for long-term monitoring and
research. It is a State-Federal part-
nership managed by NOAA under
the Coastal Zone Management Act.
The Act requires nomination of a
reserve site by the Governor of a
State and designation by the Secre-
tary of Commerce. Since 1972,
NOAA has kept this partnership,
and the evolving statutory mission
of the program, by providing
resources and guidance to the
States, by developing national  pro-
grams, and by shaping the legisla-
tion into an operating program.
Twenty-one reserves have been
designated including sites in Hawaii,
Puerto Rico, the Great Lakes, the
Gulf of Mexico, the Atlantic Coast,
and the West Coast.

•  Tennessee Valley Authority,
Water Resource Monitoring

TVA conducts a regional water
resource monitoring program to
evaluate ecological health and suit-
ability for body-contact recreation of
reservoirs and major streams in the
Tennessee Valley and to evaluate
the suitability for human consump-
tion of fish in those waters. The
program includes systematic mea-
surement of physical, chemical,  and
biological variables at strategic loca-
tions. Results are used to draw
attention to pollution problems, to
set cleanup goals, and to measure
the effectiveness of water quality
improvement efforts over time. TVA
also monitors aquatic plant and
mosquito populations around TVA
lakes to help target management
efforts. Monitoring of conditions in
tailwaters below several dams
focuses on  prioritizing facilities for
reaeration of reservoir releases and
providing data to evaluate the
effectiveness of those efforts.
•  U.S. Department of Agriculture,
Resource Conservation Act of 1977

Mandated by the Resource Conser-
vation Act (RCA) of 1977, the USDA
is "to provide for furthering the
conservation, protection, and
enhancement of the Nation's soil,
water, and related resources for
sustained use." In recognition of the
importance of, and need for,
obtaining and maintaining informa-
tion on the current status of soil,
water, and related resources, USDA
makes a continuing appraisal of the
soil, water, and related resources of
the Nation. The objective of the
appraisal currently under way is to
present information to assist policy
decisionmakers and program man-
agers to form better policies and
programs to address soil, water, and
other environmental concerns for
the next 2 decades.

RCA appraisals include data on: the
quality and quantity of soil, water,
and  related resources, including fish
and  wildlife habitats; the capability
and  limitations of those resources
for meeting current and projected
demands on the resource base; the
changes that have occurred  in the
status and condition of those
resources resulting from various past
uses, including the impact of farm-
ing technologies, techniques, and
practices; and the current Federal
and  State laws, policies, programs,
rights, regulations, ownerships, and
their trends and  other consider-
ations relating to the use, develop-
ment, and conservation of soil,
water, and related resources.

    Developed by the Interagency
Work Group on Water Quality, the -
Guide to Federal Water Quality Pro-
grams and Information is an  attempt
to inventory all significant Federal
water quality programs and  infor-
mation of national scope or  interest.
The  guide contains information on
(1) factors affecting water quality
including underlying demographic
pressures; use of the land, water,
and  resources; and pollutant load-
ing;  (2) ambient water quality infor-
mation, including biological, chemi-

305(b)  Consistency
Workgroup

   The 305(b) Consistency Work-
group, convened  in 1990, was
expanded  in 1992 and 1994  to
address issues of consistency in
water quality reporting and to
improve accuracy and coverage of
State assessments. The 1994 305(b)
Consistency Workgroup consists of
representatives of 23 States, 3
Tribes, 1 Territory, 1 Interstate Com-
mission, 6 Federal agencies, the 10
EPA Regions, and EPA Headquarters.
This standing workgroup, which  will
develop future 305(b)  guidance,
makes recommendations to improve
each iteration of guidance to  the
States. Recent recommendations
have included refining total State
waters estimates and providing
more  detailed guidance for aquatic
life use support assessments, includ-
ing appropriate methods for using
biological data along with physical
and chemical data.

Biological Monitoring

The Biological Criteria
Program

    Priorities established since  1987
(initiated jointly by the States and
EPA) encourage the States to first
develop, and then adopt as  appro-
priate, narrative and quantitative
biological criteria (biocriteria) into
their water quality standards and
assessment programs. This success-
ful approach has resulted in  about
30 States developing quantitative
biocriteria, including three States
that formally adopted quantitative
biocriteria into their water quality
standards. For the status of specific
State programs,  please refer to
Appendix G.
    To support this priority,  the
Agency has provided  guidance for
development and implementation
of biocriteria (see sidebar). Several
future guidance documents will
provide additional technical infor-
mation to facilitate activities directed
toward that implementation. When
fully implemented, biocriteria will
expand and improve water quality
standards programs, help to quan-
tify impairment of beneficial uses,
and aid States and Tribes in setting
program priorities. These criteria will
be useful because they provide for
             EPA Publications About Developing and
                      Implementing Biocriteria

                                     mentation of water resource quality
                                     programs. Biocriteria are intended
                                     to supplement, rather than replace,
                                     chemical and toxicological methods.

                                     Bioassessment Protocols

                                         in  1989, EPA's Office of Water
                                     issued rapid bioassessment protocols
                                     (RBPs) for streams as a tool
                                     intended to provide States with
                                     biological monitoring methods to
                                     supplement traditional  instream
                                     chemical analyses. The key concept
                                     underlying these protocols is the
                                     comparison of the structure and
                                     function of the aquatic community
                                     in the context of habitat quality at a
                                     given stream study site to that of an
                                     ecological reference site or condi-
                                     tion. On the basis  of this compari-
                                     son, a water resource quality assess-
                                     ment can be made. EPA has pro-
                                     vided technical support and training
                                     to States to encourage the imple-
                                     mentation of the RBPs and biologi-
                                     cal criteria. Currently, over 30 States
                                     have active RBP-based water
                                     resource monitoring programs for
                                     streams, another three  are under
                                     development, and three States go
                                     beyond the guidelines. Updated RBP
                                     guidance is being developed to aid
                                     States in adapting  the original pro-
                                     tocol framework to go  beyond a
                                     single reference site approach to
                                     including ecbregional reference
                                     conditions that fit a variety of eco-
                                     logical regions. Over 30 States
                                     either have, Or are developing,
                                     ecoregional reference conditions.
Modified RBPs are also being pre-
pared for other water resource types
including lakes/reservoirs and estuar-
ies. Work is also under way to evalu-
ate the effectiveness of RBPs for
assessing combined sewer over-
flows. In  addition, a generic quality
assurance/quality control (QA/QC)
guidance will be available in the Fall
of 1995.  For a copy,  please contact
the EPA Monitoring Branch at 202-

Quality Assurance/Quality
Control for Biological
Monitoring and Biological
Assessment

    The U.S. EPA Office of Water
and Office of Research and Develop-
ment are assembling  generic guid-
ance documents for production of
quality assurance project plans for
biological monitoring and assess-
ment. This work is currently under
way and  involves review and input
from State and EPA regional moni-
toring personnel.

Fish Advisory Guidance
and Databases

    In response to interest on the
part of States to have nationally
consistent methods for issuing fish
consumption advisories, EPA's Office
of Science and Technology (OST),
Standards and Applied Science Divi-
sion, is developing national guid-
ance documents. This guidance,
developed in cooperation  with
States, Tribes, and others, is pre-
sented in a four-volume set of docu-
ments titled Guidance for Assessing
Chemical Contaminant Data for Use
in Fish Advisories, Volume I: Fish Sam-
pling and Analysis (September

1993); Volume II: Risk Assessment
and Fish Consumption Limits (June
1994); Volume III: Risk Management
(FY95); and Volume IV: Risk Commu-
nication (FY95).
    In addition to this guidance,
OST has developed two databases,
one for States to report fish advisory
information and another that con-
tains fish tissue contaminant data.
The Fish Advisory Database contains
fish advisory information reported
nationwide by States including the
waterbody affected,  the type of fish
species, the type of advisory, and  a
contact person.  It is  updated annu-
ally and can be  obtained by con-
tacting the EPA  Fish  Contaminants
Section at the following address or
by calling  (202) 260-1305:

       Technology

    OST established  the National
Fish Tissue Data Repository (NFTDR)
to (1) simplify data exchange by
improving the comparability and
integrity of fish tissue data;
(2) encourage greater regional and
interstate cooperation; and (3) assist
States and Tribes in their data col-
lection efforts by providing ongoing
technical assistance.  Currently, the
NFTDR is part of EPA's Ocean Dis-
charge Evaluation System (ODES)
Database and there is relatively little
fish tissue  data in the NFTDR. To
make the NFTDR more accessible,
EPA intends to modify the NFTDR
and incorporate it as a major proto-
type during the  modernization
(Phase III)  of EPA's STORET
(STOrage and RETrieval) Database
(see page 374 for more information
about STORET and ODES). The use
of real fish tissue data during proto-
type development should  help EPA
identify needed  data fields and test
the data structure.
    During 1996, EPA intends to
completely convert the NFTDR to a
STORET-based fish tissue database.
The primary benefit of including the
NFTDR as a subset of STORET is
that one "platform" will be able to
store both water quality data and
biological data,  such as fish tissue
information. Existing data  sets
would be able to easily migrate to
the new STORET system when it is
completed  in 1997. Additional infor-
mation may be  obtained by writing

National Study of
Chemical Residues in Fish

    In late 1992, EPA issued a
report on results of the EPA National
Study of Chemical Residues in Fish
(NSCRF), formerly called the
National Bioaccumulation  Study.
This study is a followup to the EPA
National Dioxin  Study and substan-
tially broadens that work with
regard to both the number of
chemicals analyzed and the number
of sites examined. The NSCRF was a
screening study  designed to deter-
mine the extent to which  water
pollutants are bioaccumulating in
fish and to  identify correlations with
sources of the contamination within
a watershed/drainage basin.

databases and information
systems, see the Office of

Specific Water
Program Monitoring

National Estuary
Program Monitoring
Guidance

    EPA is developing guidance on
the design, implementation, and
evaluation of estuary monitoring
programs required under Section
320 of the Clean Water Act. The
guidance document identifies the
major steps involved in developing
and implementing estuary monitor-
ing programs,  documents existing
monitoring methods, and describes
their use in monitoring the effective-
ness of estuarine management
actions. Case studies of existing
programs are included.

Nonpoint  Source
National Monitoring
Program

    EPA developed the Section 319
National Monitoring Program to
improve our understanding of
nonpoint source (NPS) pollution
and to scientifically evaluate the
effectiveness of NPS pollution con-
trol activities. Under this program,
EPA's Regional Offices nominate
projects by forwarding State propos-
als to EPA Headquarters for review
and concurrence. Projects are
selected on a competitive basis from
within each of the EPA Regions. EPA
works with project sponsors to de-
velop approvable 6- to 10-year
projects. The project sponsors then
work through the State/EPA Section
319 process to obtain approval
and funding. As of June 1995,
11 projects have been approved.
More information about the Section
319 National Monitoring Program is
provided in Chapter 15.

Wetlands Monitoring

    EPA's Wetlands Division is now
working closely with FWS and EPA's
EMAP-Wetlands Program to charac-
terize the ecological status and
trends of existing wetlands. Stan-
dardized protocols are being devel-
oped for measuring wetlands
conditions. See Chapter 15 for
further information about EPA and
State wetlands monitoring and
protection programs.

Ground Water
Monitoring

    EPA's support for State Ground
Water Protection Programs has
expanded in line with the Ground
Water Task Force's recommenda-
tions in the report Protecting-the
Nation's Ground Water: EPA's Strat-
egy for the 1990's. This document
addresses the development of con-
sistent data collection protocols to
improve accessibility, quality, and
the usefulness of ground water qual-
ity data. To that end, the Ground
Water Minimum Set of Data Ele-
ments for Ground Water Quality
was finalized requiring their use for
EPA ground water monitoring.

Volunteer Monitoring
Programs

    EPA's Office of Water encour-
ages all citizens to learn about their
water resources and supports volun-
teer monitoring because of its many
benefits. Volunteer monitors

•  build awareness of pollution
problems

•  become trained in pollution
prevention

•  help clean up problem sites

•  provide data for waters that may
otherwise be unassessed, with
accompanying  data on the methods
used to collect  the data

•  increase the amount of water
quality information available to
decisionmakers at  all levels of
government.

    Among  the uses of volunteer
data are delineating and characteriz-
ing watersheds, screening for water
quality problems, and  measuring
baseline conditions and trends.
    EPA supports volunteer monitor-
ing by providing technical guidance
and forums  for exchanging volun-
teer information. For example, EPA
sponsors biennial national confer-
ences that bring together volunteer
organizers, State and local agencies,
environmental groups, school
groups, and the business sector. EPA
also maintains an electronic bulletin
board forum for volunteer monitors,
distributes a national newsletter for
volunteers, and  maintains a direc-
tory of volunteer monitoring pro-
grams across the Nation. EPA has
released guidance  for planning and
implementing volunteer monitoring
programs as well as guidance cover-
ing volunteer monitoring methods.
    Many of EPA's 10  Regional
Offices are actively involved in vol-
unteer monitoring. Their support
activities  include providing technical
assistance related to quality assur-
ance and  quality control, serving as
contacts for volunteer programs in
the Region, managing grants to
State agencies that include provi-
sions for volunteer water monitoring
and  public participation, and
providing  information exchange

enhance sharing of data (across
EPA, other Federal, State, and local

ODES are undergoing a major
modernization scheduled to be
complete in 1997 with interim
products throughout, including a
full prototype in late 1995. This
effort will result in a more flexible,
efficient, and usable state-of-the-art
information system, which, in turn,
will provide improved tools for
ground and surface water quality
decisionmaking.

ments. During the 1994 reporting
cycle, 27 States, Territories, and
Interstate Water Commissions
submitted WBS data files.
    The Waterbody System contains
information that program managers
can access quickly on the water
quality status of a particular water-
body. Data elements include water-
body identification, water quality
status, assessment information,
designated use evaluations, causes
of impairment (nutrients, pesticides,
siltation, etc.),  and sources of
impairment (municipal treatment
plants, agricultural runoff, etc.).
    Enhanced twice since it was
originally developed in 1988, system
users communicate regularly with
each other and can receive user
information and support from  the
Monitoring Branch at EPA Head-
quarters.

The Permit Compliance
System

    The Permit Compliance System
(PCS) is an information  manage-
ment system maintained by the
Office of Wastewater Enforcement
and Compliance (OWEC) to track
the permit, compliance, and
enforcement status of facilities regu-
lated by the National  Pollutant
Discharge Elimination System
program under the Clean Water
Act. PCS tracks information about
wastewater treatment and industrial
and Federal facilities discharging
into navigable  rivers. Tracked items
include facility  and discharge
characteristics,  permit conditions,
inspections, enforcement actions,
and compliance schedules. PCS
distinguishes between major and
minor facilities based on the poten-
tial threat to human health or the
environment. Only major facilities
must provide complete records to
PCS, currently numbered at around
7,100;  however, States and Regions
do submit information for approxi-
mately 56,300 minor facilities. PCS
users are able to use graphical and
statistical tools to analyze PCS data
and can use a PCS/STORET interface
to link the systems and  support
additional analyses.

The Toxics Release
Inventory

    The Emergency Planning  and
Community Right-to-Know Act
(EPCRA) of 1986 established the
Toxics Release Inventory (TRI), a
public database that contains infor-
mation about toxic chemical
releases to water, air, and  land from
manufacturing facilities. The TRI
contains data submitted annually by
individual manufacturing facilities
subject to the EPCRA reporting
requirements. The EPCRA reporting
requirements apply to manufactur-
ing facilities that

•  Employ 10 or more full-time
employees

•  Manufacture or process over
25,000 pounds of any chemical or
chemical category listed in the
EPCRA, or use more than 10,000
pounds of any chemical or chemical
category listed in the EPCRA

specified in the U.S. Government
Standard Industrial Classification
(SIC) Codes 20 through 39, includ-
ing chemicals, petroleum refining,
primary metals, fabricated metals,
paper, plastics, and transportation
equipment (see sidebar).

    The EPCRA regulations  require
that eligible manufacturing facilities
identify the toxic chemicals they
released (from a list of more than
300 individual chemicals and 20
chemical categories); the quantity of
each chemical released to the air,
water, and land; and the quantity of
each chemical transferred off site for
treatment, disposal, or recycling. In
response to the Pollution Prevention
Act of 1991, facilities are also
required to report additional infor-
mation about waste management
and source reduction activities. The
reported data are stored in the TRI
and in State files available to the
public.
    The TRI database  provides the
public with direct access to toxic
chemical release and transfer data at
the local,  State, regional, or national
level.  The public can use the TRI
data to identify potential concerns
in local waterbodies or throughout
the Nation. With TRI data, the pub-
lic can work with industry and gov-
ernment to reduce toxic chemical
releases and the risks associated
with them.
    Industry can use the TRI data to
obtain an overview of use and
release of toxic chemicals, to iden-
tify and reduce costs associated with
toxic waste, to identify promising
areas  of pollution prevention, to
establish reduction targets, and to
measure and document progress
toward chemical release reduction
goals. The public access of the TRI
data has prompted many facilities
to work with their  communities to
develop effective strategies for
reducing environmental and human
health risks posed by toxic chemical
releases.
    Federal, State,  and local govern-
ments can use the TRI data to iden-
tify hot spots, compare facilities or
geographic areas, evaluate pollution
control and  prevention programs,
and track progress in reducing
waste. The Office of Water has used
TRI data with other pertinent
exposure and toxicity data to iden-
tify and prioritize contaminants in
drinking water, to  identify and
quantify inputs of toxic chemicals
into the Gulf of Mexico, and to
compile data on toxic releases into
municipal treatment plants.
    The TRI database has some
limitations. TRI  captures only a por-
tion of all toxic chemical releases
nationwide because nonindustrial
sources, such as dry cleaners and
auto service stations, are not
required to submit TRI data. In ad-
dition, the TRI data alone  are not
sufficient to calculate potential
adverse effects  on  human  health
from toxic chemicals because TRI
does not track exposure of the
public to released chemicals.
    The TRI data are available to
the public online through  the Na-
tional Library of Medicine's TOXNET
system and through the Right-to-
Know Network (RTK NET), which is
sponsored by the Unison Institute, a
nonprofit organization. TRI data are
also available on CD-ROM and on
individual State diskettes. For infor-
mation about obtaining TRI  data,

the public can call the TRI User
Support Service (202-260-1531) or
the EPCRA Information Hotline
(1-800-535-0202).
    TRI users can obtain additional
information about health effects and
ecotoxicity of chemicals in the TRI
database from PC-TRI FACTS, an
auxiliary software package devel-
oped by EPA.

Contaminated Sediment
Strategy

    In early 1993, EPA issued its
Contaminated Sediment Manage-
ment Strategy: A Proposal for Dis-
cussion. Then, in August 1994, the
Strategy Document, EPA's  Contami-
nated Sediment Management Strat-
egy, was announced in the Federal
Register. One of its main objectives
is to describe EPA's current under-
standing of the extent and severity
of sediment contamination. EPA's
Contaminated Sediment Manage-
ment Strategy describes actions that
the Agency will take to accomplish
the following four strategic goals:
(1) prevent further sediment
contamination that may cause unac-
ceptable ecological  or human health
risks; (2) when practical, clean up
existing sediment contamination
that adversely affects the Nation's
waterbodies or their uses, or that
causes other significant effects on
human health or the environment;
(3) ensure that sediment dredging
and dredged material  disposal con-
tinue to be managed in an environ-
mentally sound manner; and (4)
develop and consistently apply
methodologies for analyzing  con-
taminated sediments. To accomplish
these goals, EPA will continue to
develop and improve methods for
 identifying contaminated sediments,
 to provide a basis for assessment of
 sediment contamination, to outline
 steps to reduce risk supported by
 sound science, and to outline a
 strategy for assessing the extent and
 severity of sediment contamination.
    One of the initial steps to imple-
 ment not  only this strategy but to
 meet mandated statutory require-
 ments to address and resolve con-
 taminated sediment problems is to
 develop national inventories of con-
 taminated sediment sites and pollut-
 ant sources (point and nonpoint).
 During the past 3 years, EPA's Office
 of Science and Technology has
 compiled the National Sediment
 Inventory  (NSI), an extensive
 geographically referenced database
 of sediment quality monitoring and
 pollutant source information for the
 Nation's freshwater and estuarine
 ecosystems. The Site Inventory com-
 ponent of the NSI contains detailed
 monitoring data on sediment chem-
 istry and biological effects collected
 by Federal and State agencies
 beginning in 1980. The Point
 Source Inventory component of the
 NSI contains over 22,000 individual
 records of point source discharges
 of 118 different chemicals from
 municipal, Federal, and industrial
 facilities in 1992. The NSI database
 will be continually updated and
 improved.  Based on an evaluation
 of current  data, OST will produce
 an assessment of the national  extent
 and severity of sediment contamina-
 tion across the country and present
 the results  in a Report to Congress
 in early 1996.

 NSI,  contact the OST Standards and

                                     the NPS News-Notes, published
                                     approximately eight times per year,
                                     and the NPS Electronic Bulletin
                                     Board System (NPS  BBS). The target
                                     audience for the News-Notes is State
                                     and local water quality managers
                                     although, with a circulation of over
                                     10,000, other interested parties
                                     including public officials,

Great Lakes Envirofacts

    The Great Lakes National Pro-
gram Office (GLNPO) is initiating a
computer system development pilot
effort called Great Lakes Envirofacts
(CLEF) to assist managers and tech-
nical staff in developing strategies to
reduce toxic chemical loadings. The
keystone goal of GLNPO's data inte-
gration program is  the development
of a system to enable technical staff
to access, display, analyze, and
present Great Lakes multimedia and
geographic information from their
desk top, providing environmental

                                                  Chapter Thirteen  Water Monitoring and Assessment Programs  379
decisionmaking support for Great
Lakes Program managers. The CLEF
pilot project will explore both the
system requirements of Great Lakes
Program staff and the technical
means (hardware, software, and
telecommunications) to begin realiz-
ing its keystone goal.
    The CLEF will build upon the
Envirofacts/Gateway system devel-
oped by EPA's Office of Information
Resources  Management (OIRM)
Program Systems Division (PSD).
The Envirofacts database stores envi-
ronmental monitoring and program
(e.g., PCS, TRIS, FINDS) information
in a relational structure. Gateway is
a graphical user interface that pro-
vides spatially referenced access to
the Envirofacts database. The Great
Lakes Envirofacts project will  be the
first implementation of the Gate-
way/Envirofacts concept, testing its
capability and utility for the Great
Lakes Program.

Other Information
Clearinghouses &
Electronic Bulletin Boards

    Several other clearinghouses,
electronic  bulletin boards, newslet-
ters, and information updates on
water quality  activities have been
developed by EPA for use by State
and local governments, Federal
agencies, and the public. These
include COASTNET bulletin board
for coastal waters and estuary pro-
tection activities, the Clean Lakes
Clearinghouse, the Contaminated
Sediment News bulletin, and the
Office of Science and Technology's
Resource Center.

                                         The Office of Water's Office of
                                      Wetlands, Oceans, and Watersheds
                                      has established the Water Channel
                                      on EPA's Internet site. The Water
                                      Channel  broadcasts water informa-
                                      tion and  tools for communities and
                                      American citizens to understand

of about 12,000 ground water and
more than 22,000 surface water
samples. These data were inter-
preted on regional and national
scales by relating the distributions of
nutrient concentrations to ancillary
data, such  as land use, soil
characteristics, and hydrogeology.
   Nitrate was the  nutrient of
greatest concern  in ground water. It
is the only nutrient that is regulated
by a national drinking water stan-
dard. Nitrate concentrations in
ground water were elevated prima-
rily in agricultural areas (see Figure
1). Concentrations in about 16% of
the samples collected in agricultural
areas exceeded the drinking water
standard. Concentrations were high-
est in shallow ground water, less
than 100 feet below land surface.
The standard was exceeded in only
about 1 % of samples collected from
public supply wells.
   A variety of factors influenced
nitrate concentrations in ground
water beneath agricultural areas.
Concentrations were higher in areas
where soil  and geologic characteris-
tics promoted rapid movement of
water to the aquifer. Elevated

 concentrations commonly occurred
 in areas underlain by permeable
 materials, such as carbonate bed-
 rock or unconsolidated sand and
 gravel,  and where soils are generally
 well drained.
    In areas where water movement
 was impeded, denitrification might
 lead to low concentrations of nitrate
 in the ground water. Low concen-
 trations were also related to  inter-
 spersion of pasture and woodland
 with cropland in agricultural areas.
 Elevated nitrate concentrations in
 areas of more homogeneous crop-
 land probably were a result of inten-
 sive nitrogen fertilizer application on
 large tracts of land. Because  of the
 time involved for ground water to
 move vertically in some areas, the
 full effect of current nitrogen
 fertilizer applications might not be
 noted in some aquifers for many
 years. Likewise, the effects of imple-
 menting management practices to
 improve water quality might not be
 evident for many years.
    Certain regions of the United
 States seemed more vulnerable to
 nitrate contamination of ground
 water in agricultural areas. Regions
 of greater vulnerability included
 parts of the Northeast, Midwest,
 and West Coast. The well-drained
 soils typical in these regions  have
 little capacity to hold water and
 nutrients;  therefore, these soils
 receive some of the largest applica-
 tions of fertilizer and irrigation in
the Nation. The agricultural land is
 intensively cultivated for row crops,
with little  interspersion of pasture
 and woodland. Regional patterns
and the distribution of local charac-
teristics could be useful in identify-
ing areas of potential nitrate
problems.
    Nutrient concentrations in
surface water also were generally
related to land use. Nitrate concen-
trations were highest in samples
from sites downstream from agricul-
tural or urban areas (see Figure 2).
However, concentrations were not
as high as in ground water and
rarely exceeded the drinking water
standard.  Elevated concentrations of
nitrate in surface water of the north-
eastern United States might be
related to large amounts of atmos-
pheric deposition (acid rain). High
concentrations in parts of the  Mid-
west might be related to tile drain-
age of agricultural fields.

WA  "Vital  Signs" Monitoring
    About 10 years ago, the Tennes-
see Valley Authority (TVA) began a
thorough review of its traditional
water quality monitoring efforts.
Familiar issues—budget pressures
and the "data-rich, information-
poor" syndrome—were the motivat-
ing factors. From that initial review
and subsequent critical scrutiny, TVA
has developed a "vital signs"  moni-
toring program that reports to the
public each spring on the fishability,
swimmability, and ecological  health
of 30 TVA reservoirs  and major
tributaries.
    The annual report is a user-
friendly magazine, RiverPulse,  that is
mailed to about 13,000 individuals
who have called to request it and is
distributed through marinas, parks,
TVA visitor centers, and other public
outlets. Feedback from readers indi-
cates that this annual report is well
received and very effectively com-
municates technical information to
nontechnical audiences. Many of its
features are being adopted by other
organizations that report to the
public on environmental conditions.
    RiverPulse summarizes monitor-
ing information collected during the
previous spring, summer, and fall.
Informal technical reports document
monitoring methods, analyses, and
results. The monitoring program
integrates physical and chemical
monitoring of streams and  reservoir
waters with quantitative evaluations
of benthic invertebrate and fish
communities to develop an ecologi-
cal health rating for each lake. A
sediment chemistry and toxicity
component of the rating was elimi-
nated in 1995 as a result of budget
constraints. Fish tissue contamina-
tion monitoring and associated
State-promulgated fish consumption
advisories provide information on
fishability, and results of bacterio-
logical sampling at beaches and
informal recreation areas are the
basis for the swimmability ratings.

Treating Municipal
Wastewater

     Municipal treatment facilities
receive wastewater from residential
sources as well as from industry and
storm water runoff. The array of
pollutants that may be associated
with these sources includes sus-
pended solids, organics, pesticides,
heavy metals, nutrients, acids,
viruses, and bacteria.
    Adequate treatment of munici-
pal wastewater is important for the
protection of the Nation's water
resources and public health. With-
out adequate treatment, this pollu-
tion poses a serious threat to
aquatic life, commercial and recre-
ational opportunities, surface water
drinking supplies, ground water
drinking supplies, and the general
health and stability of the Nation's
stream, river, lake, estuarine, and
coastal ecosystems.
    The Clean Water Act  requires
municipalities to achieve treatment
levels based on technology perfor-
mance. The 1981 CWA amend-
ments extended the deadline for
eligible treatment plants to achieve
"secondary treatment" to July 1,
1988. Secondary treatment removes
at least 85% of several key conven-
tional pollutants. If secondary treat-
ment is not enough to meet water
quality standards, the Clean Water
Act mandates additional treatment
as necessary.
    Historically, under the Clean
Water Act, EPA has been authorized
to help municipalities solve their
wastewater treatment problems by
providing grants for construction.
Since 1972, EPA, through the
Construction Grants Program, has
provided approximately $54 billion
to municipalities to construct or
improve their wastewater treatment
systems.
    In the 1987 Amendments to
the Clean Water Act, Congress and
the President agreed to phase out
the Construction Grants Program. In
its place, the State Revolving Fund
(SRF) was created and has resulted
in the creation of revolving loan
funds in each  State and  Puerto Rico.
The goal of the SRF program is to
establish independent and perma-
nent sources of funding  in each
State. Capitalization of these funds
is provided by the Federal (80%)
and State (20%) governments.
Congress appropriated more than
$10.3 billion through fiscal year
1995 for State Revolving Funds. In
addition to providing loans for con-
struction of wastewater treatment
facilities, SRFs allow funding  for
many activities not previously
eligible under the Construction
Grants Program, including control
of nonpoint source runoff and
estuary protection projects.

                                       The Amendments of 1987 also
                                   included new water quality require-
                                   ments. The primary programs with
                                   new enforceable requirements are
                                   those dealing with storm water,
                                   toxic discharges, and sludge use
                                   and disposal. The SRF loan program
                                   provides States with more discretion
                                   than ever before in selecting
                                   projects for funding. States are now
                                   able to finance projects they may
                                   consider to be of higher priority,
                                   such as nonpoint source, estuarine,
                                   combined sewer overflow, or storm
                                   water control projects. All States and
                                   Puerto Rico had approved SRF
                                   programs in place as of September
                                   1990.
                                        EPA has awarded  over $11.1
                                   billion to States to capitalize SRF
                                   programs since  1988. States have
                                   contributed about $2.2 billion to
                                   meet the 20% match requirement.
                                   In addition, 21 States have issued
                                   about $5.4 billion in leverage bonds
                                   to further capitalize their SRF
                                   programs. From these and other
                                   sources, capitalization of SRF
                                   programs totals about $19 billion
                                   through fiscal year 1995.
                                        The Administration remains
                                   committed to the State Revolving

                                        The Needs  Survey, a biennial
                                    report to Congress, is the primary
                                    mechanism for  assessing municipal
wastewater treatment needs
nationwide. The 1992 Needs Survey
focuses on the expanded CWA
funding eligibilities under the SRF in
the 1987 Amendments'to the Clean
Water Act. Models were used to
supplement documented needs
estimates for combined sewer over-
flows. Models were also used to
develop preliminary urban storm
water and agricultural and silvicul-
tural nonpoint source pollution
control implementation costs since
very little documentation of specific
projects or costs was available from
the States.
    EPA's needs estimates include
those facilities and activities for
which a water quality or public
health problem could be docu-
mented using specific criteria
established by EPA. The capital
investment necessary to satisfy all
categories of need is presented in
Table 14-1. Costs for operation and
maintenance are not eligible for SRF
funding and therefore are not
included. Additional  nonconstruc-
tion estimates are included for pro-
gram development costs associated
with storm water and NPS control.
The 1992 total documented and
modeled needs are $137.1 billion to
satisfy all categories of needs eligible
for SRF funding for the design year
(2012) population.
    This amount included $50.1
billion in  modeled needs for CSO,
storm water, and NPS pollution
control. For storm water and NPS,
the estimates exclude operation and
maintenance costs (O&M) since
O&M costs are ineligible for SRF
funding.  However, O&M costs are
the major costs associated with
storm water and NPS program
implementation. Only agriculture

and silviculture NPS pollution
control costs were estimated. Many
types of NPS pollution were  not
addressed: abandoned mines, urban
areas, septic systems, contaminated
sediments, hydromodification, and
atmospheric deposition.
    The needs estimate for the
Nation rose in constant dollars by
$53.4 billion (39%) from 1990 to
1992. The increase was due  to a
variety of factors,  primarily
improved documentation of  SRF
eligibilities and the use of models to
capture full CSO,  as well as partial
urban storm water and NPS  costs.
Treating  Industrial

    The Clean Water Act required
EPA to establish uniform, nationally
consistent effluent limitation guide-
lines for industrial discharges. At this
time, EPA has established Best Avail-
able Technology Economically
Achievable (BATEA) and Best Con-
ventional Pollutant Control Technol-
ogy (BCT) guidelines for about 28
industrial categories. EPA has also
promulgated technology-based

trol Technology Currently Available
(BPT) levels. EPA is studying an
additional dozen industries for
future guidelines development.
    In addition to these technology-
based requirements, EPA, in 1984,
issued a policy on the water-quality-
based control  of toxic pollutants
discharged by point sources. In
1985, EPA issued the Technical Sup-
port Document for Water Quality-
Based Toxics Control to support the
national policy. EPA updated and
enhanced this document in 1991.
Both the policy and guidance rec-
ommend  using overall toxicity as a
measure of adverse water quality
impact and as a regulatory
parameter. In  1989, EPA amended
its NPDES regulations to clarify the
use of effluent discharge limitations
for whole-effluent toxicity in addi-
tion to specific toxic chemicals. The
use of whole-effluent toxicity as a
regulatory tool coupled with con-
trols for specific chemicals provides
a powerful means of detecting and
controlling toxic problems.

Permitting,
Compliance,
and Enforcement

    EPA and the States use  rigorous
permit conditions to  control point
source discharges from industrial
and municipal wastewater treatment
facilities. During the early 1980s, the
rate of permit issuance fell behind
the rate of permit expiration, and
large backlogs of unissued permits
developed. Efforts to remedy these
backlogs have been largely  success-
ful, especially for major permits.
Table 14-2 illustrates the status of
permit issuance as of February
1993.
    Once the permit is established,
compliance with these conditions is
essential for achieving water quality
improvements. Despite examples of
water quality improvements associ-
ated with upgrading municipal
facilities,  10% of major municipal
treatment plants are in significant
noncompliance with applicable per-
mit conditions. Industrial permittees
have historically achieved a higher
rate of compliance;  7% of industrial
facilities are in significant noncom-
pliance with their permit conditions.
    EPA and States with approved
NPDES programs are responsible for
ensuring that municipal and
industrial facilities comply with the
terms of their discharge permits.
Currently, 40 States have approval
from EPA to administer their own
NPDES programs. This responsibility
includes issuing permits, conducting
compliance inspections and other
compliance monitoring activities,
and enforcing compliance. EPA has
the lead  implementation responsibil-
ity in the remaining States. EPA and
the States evaluate compliance by
screening self-monitoring reports
submitted by the permitted facility.
Facilities that are determined to  be
in noncompliance are subject to
Federal as well as State enforcement
action.
    Figure 14-1 illustrates rates of
significant noncompliance based on
statistics  maintained by EPA from
March 1988 through  December
1994.  Significant noncompliance is
based  upon violations of a permit,
administrative order, and judicial,
order requirements. Examples of
violations for permits include
exceedances of monthly average
effluent limits at least twice during a

6-month period or any exceedance
of limits set by an administrative
order. Discharge monitoring reports
or pretreatment schedules more
than 30 days late are also consid-
ered in significant noncompliance.
Significant noncompliance rates for
municipal and industrial facilities
jumped in FY90 primarily because,
for the first time, EPA calculated
noncompliance directly from its
automated database. Therefore, if
data are not entered into the Permit
Compliance System in a timely
manner, the system will automati-
cally determine that the facility is

                       not in compliance. EPA is continu-
                       ing to refine its tracking of compli-
                       ance with permit conditions to bet-
                       ter reflect instances of noncompli-
                       ance by the regulated community.

                       National Municipal
                       Policy

                           Due to the generally poor
                       municipal compliance record, and
                       because of congressional concern
                       over the performance of treatment
                       works built primarily with Federal
                       funds, EPA developed the National

                                     Municipal Policy (NMP) to address
                                     the failure of publicly owned treat-
                                     ment works (POTWs) to meet treat-
                                     ment levels required for compliance
                                     with the CWA. On January 23,
                                     1984, the EPA Administrator signed
                                     the NMP into effect. The NMP clari-
                                     fied and emphasized EPA's resolve
                                     to ensure that municipalities comply
                                     with the Clean Water Act as quickly
                                     as possible, regardless of whether
                                     Federal grant assistance was
                                     available for treatment plant
                                     construction.
                                        The deadline established for full
                                     compliance with the Clean Water
                                     Act was July 1, 1988. By this date,
                                     all municipal treatment facilities
                                     were to be in compliance with the
                                     secondary treatment requirement of
                                     Section 301(b)(1)(B) of the CWA or
                                     with more stringent limitations
                                     established to meet State water
                                     quality standards. Of the total
                                     universe of 3,731 major municipal
                                     facilities, 1,478 facilities were identi-
                                     fied as requiring construction to
                                     meet the 1988 deadline. By July 1,
                                     1988, all but 423 municipal facilities
                                     had achieved compliance with the
                                     requirements. Since the 1988 dead-
                                     line, 188 facilities have come into
                                     compliance, and, of the remaining
                                     235 facilities, all  but 50 have been
                                     placed on enforceable compliance
                                     schedules. EPA is continuing to track
                                     the progress of these facilities in
                                     meeting the requirements of the
                                     CWA.
                                        In the 1987 Water Quality Act
                                     amendments to  the CWA, EPA was
                                     given authority to seek administra-
                                     tive penalties from permittees in
                                     noncompliance with the Act's
                                     requirements. EPA issued guidance
                                     and delegated the authority for
                                     issuing these orders to the regional
level in August 1987. The first
Administrative Penalty Order (APO)
was issued in September 1987.
Through October 1990, 396 APOs
have been issued assessing a total of
$7.5 million  in penalties. These
orders have been an effective tool in
expeditiously addressing violations
of the CWA and represent an inte-
gral component of EPA's overall
enforcement strategy.

Controlling Toxicants

    The 1987 amendments to the
Clean Water Act reinforced both the
water-quality-based and technology-
based approaches to  point source
control, requiring EPA to develop
and update technology-based stan-
dards and adding specific direction
as to how water-quality-based  limits
should be used  to achieve addi-
tional improvements. One of the
Act's primary emphases lay in
strengthening the Nation's toxics
control program.

Identifying Waters
Impaired by Toxicants

    Section 304(1) of the CWA
required States to develop lists of
impaired waters, identify point
sources and the amounts  of pollut-
ants they discharge that cause toxic
impacts, and develop an individual
control strategy (ICS) for each  such
point source. These ICSs are NPDES
permits with new or more stringent
limits on the toxic pollutants of
concern. The individual control
strategies must be accompanied  by
supporting documentation to show
that the permit  limits are sufficient
to meet water quality standards as

-------
                                                               Chapter Fourteen Point Source Control Program   393
soon as possible but no later than
3 years after establishment of the
ICS. The general effect of Section
304(1) was to immediately focus
national surface water quality pro-
tection programs on addressing
known water quality problems due
entirely or substantially to  point
source discharges of Section 307(a)
toxic pollutants.  Under Section
304(1), EPA and States identified 678
facilities in the United States that
were required to have individual
control strategies. ICSs have been
established for 593 of these facilities.
    In  developing lists of impaired
waters under Section 304(1), States
used a variety of available  data
sources (including State Section
305(b) reports). At a minimum,
dilution analyses were conducted
based on  existing or readily avail-
able data. EPA asked States to
assemble  data quickly to report
preliminary lists of waters,  point
sources, and amounts of discharged
pollutants by April 1, 1988, in their
Section 305(b) reports. These lists
were then to be refined and
expanded by the statutory deadline
of February 4, 1989
    Through the 304(1) effort, 529
waterbodies were identified as being
impaired entirely or substantially by
point source discharges of Section
307(a) toxic pollutants.  In  addition,
678 point sources were listed as
being responsible for impairing the
quality of those waters.  There are
also 18,770 waters on the "long"
list that includes all waters impaired
by any pollutant from either point
sources or nonpoint sources. Cur-
rently,  approximately 87% of the
ICSs required are in place as EPA-
approved or drafted NPDES permits.
The long list will be used for
long-term planning and setting of
priorities for activities such as moni-
toring, total maximum daily load
development, nonpoint source
controls, and permit revisions.
    EPA implements control mea-
sures for all toxic pollutants as part
of its ongoing surface water pro-
gram. Section 304(1) emphasized
implementing point source controls
to protect particularly impaired sur-
face waters for priority toxic pollut-
ants. EPA will continue identifying
impaired waters  and controlling the
discharge of toxic and other
pollutants through existing report-
ing, standards setting,  and permit-
ting programs.

Toxicity Testing

    On March 9, 1984, EPA issued
a policy designed to reduce or
eliminate toxics discharge and help
achieve the objectives of the Clean
Water Act. The "Policy for the
Development of Water Quality-
Based Permit Limitations for Toxic
Pollutants" (49 FR 9016) described
EPA's integrated  toxics control pro-
gram. The integrated  program con-
sisted of the application of both
chemical-specific and biological
methods to address the discharge of
toxic pollutants.  To support this
policy, EPA issued the Technical
Support Document for  Water Quality-
Based Toxics Control (TSD) guidance.
EPA continued the development of
the toxics control program  by revis-
ing the TSD in 1991 and by includ-
ing some aspects of the policy in
NPDES regulations at 40 CFR
122.44(d)(1)in June 1989.

                                     that will reduce effluent toxicity.
                                     EPA is currently documenting suc-
                                     cessful TREs conducted by permit-
                                     tees, States, and EPA researchers.
                                     Methods and procedures for con-
                                     ducting TREs are described in sev-

                                     referenced in the TSD.
                                         In December 1994, EPA con-
                                     ducted a survey of 50 States, 7 Ter-
                                     ritories, and 3  Tribes to determine
                                     the extent of implementation of
                                     whole effluent toxicity (WET) con-

                                     point sources.  Fifty-one jurisdictions
                                     incorporate WET limits in discharge
                                     permits based  on numeric criteria or
                                     narrative  criteria for toxics. Fifteen
                                     jurisdictions have numeric WET cri-
                                     teria (acute and/or chronic criteria)
                                     in their standards.

                                     The National
                                     Pretreatment
                                     Program

                                         The primary goal of the
                                     National  Pretreatment Program is
                                     to protect POTWs and the environ-
                                     ment from the adverse impact that
                                     may occur when toxic, hazardous,
                                     and concentrated conventional
                                     wastes are discharged into sewer
                                     systems from industrial sources. To
                                     achieve this goal, the EPA has pro-
                                     mulgated national pretreatment
                                     standards for pollutants that: (1)
                                     interfere with the operation of a
                                     POTW, including interference with
its use or disposal of municipal
sludge; or (2) pass through the
POTW and contaminate the receiv-
ing stream or are otherwise incom-
patible with the operation of the
treatment works. In addition, the
program is intended to improve
opportunities to recycle and reclaim
municipal and industrial waste-
waters and sludges. The prevention
of interference, the prevention of
pass-through, and the improvement
of opportunities to recycle waste-
water and sludge are the  three
regulatory objectives of the National
Pretreatment Program. These objec-
tives are accomplished through a
pollution control strategy  with two
elements:

• National Categorical  Stan-
dards: National technology-based
standards  developed by EPA Head-
quarters reflecting best available
technology (BAT) in establishing
effluent limits for the 126 "priority
pollutants" as well as for conven-
tional and nonconventional pollut-
ants for specific industrial  categories.

• Prohibited Discharge
Standards:

General Prohibitions:  National regu-
latory prohibitions established by
EPA against pollutant discharges
from any nondomestic user that
cause pass-through or interference
at the POTW.

Specific Prohibitions:  National regu-
latory prohibitions established by
EPA against pollutant discharges
from any nondomestic user that
cause: (1) fire or explosive hazard,
(2) corrosive structural damage,
(3) interference due to obstruction,

Local Limits:  Enforceable local efflu-
ent limitations developed by POTWs
on a case-by-case basis to reflect
site-specific concerns and imple-
ment the Federal general and spe-
cific prohibited discharge standards
as well as State and local regula-
tions.

    To ensure the success of the
pretreatment  program, EPA also
issues guidance documents and has
conducted scores of training semi-
nars to assist POTWs in developing,
implementing, and enforcing effec-
tive pretreatment programs.
    The primary focus for pretreat-
ment implementation is at the local
level since the POTW is in the best
position to regulate its industrial
users. States may become involved
in pretreatment implementation
through a formal approval process
in which the Federal Government
transfers its oversight  responsibilities
to the State. The Federal Govern-
ment, through the EPA, is involved
in pretreatment through standard
setting, policy development, and
oversight of program  implementa-
tion by approved States and POTWs
in States without approved pretreat-
ment programs. At present, 28 '
States have received approval from
EPA to administer the pretreatment
program, including five States that
have chosen to directly regulate the
industrial community in their States
in lieu of local program approval
and implementation.  In addition,
1,481 local programs have been
approved by either EPA or approved
States, and another 50 programs
are under development. The pre-
treatment program currently regu-
lates approximately 30,500 signifi-
cant industrial users (SlUs).
    On July 24,  1990, the EPA pro-
mulgated the Domestic Sewage
Study (DSS) final rule, which imple-
ments the recommendations made
in the DSS. Specifically, the rule is
designed to improve the control of
hazardous wastes discharged to
POTWs as well as strengthen the
enforcement of  pretreatment
program requirements. In addition,
the rule requires that POTWs con-
duct toxicity testing of their efflu-
ents. A continuing task will be to
integrate the implementation of
these requirements into the normal
operations of the POTWs' pretreat-
ment programs.
    The environmental accomplish-
ments of the National Pretreatment
Program have been significant.
Nationwide,  EPA estimates that
toxic pollutant loadings to POTWs
have decreased  by up to 75%
through pretreatment. In many
cases, the effects on surface water
and sludge have been dramatic.
Between 1975 and 1985, for
example, 15 POTWs discharging to
San Francisco Bay decreased their
overall metals loadings by 80%,
despite a 15% increase in POTW
flows. In Wisconsin, 14 of 24
POTWs reported marked decreases
in average total  metals concentra-
tions in their sludge after approval
of their local pretreatment pro-
grams.
    The compliance status of indus-
trial users and POTWs is an indicator
of the programmatic success of
pretreatment implementation.  Based

                                    States,  approximately 54% of signifi-

                                    with a  rate of 6% significant non-
                                    compliance for the major industries

                                    charge directly to waterbodies.
                                    According to data in EPA's national
                                    database, 39% of POTWs  are failing
                                    to implement at least one significant
                                    component of their approved
                                    pretreatment programs.
                                        EPA has focused its oversight
                                    and enforcement resources on
                                    ensuring that local municipalities
                                    properly implement their approved
                                    programs. Toward that end, on
                                    October 4, 1989, EPA announced
                                    the National  Pretreatment Enforce-
                                    ment Initiative against cities for fail-
                                    ure to adequately implement their
                                    approved pretreatment programs.  In
                                    this action, EPA joined with several
                                    States in bringing civil judicial suits
                                    or administrative penalties against
                                    61 cities. This effort was designed to
                                    alert cities as to their requirements
                                    under the pretreatment program
                                    and to ensure adequate implemen-
                                    tation of the program. A followup
                                    announcement was made on May
                                    1, 1991, containing 755 additional
                                    actions against both POTWs and
                                    significant industrial users.
                                        In July 1991, EPA issued a
                                    report to Congress on the effective-
                                    ness of the pretreatment program
                                    as required under Section  519 of
                                    the CWA. This report analyzed the
                                    major strengths and weaknesses of
                                    the program and has provided
                                    direction for improving the
                                    program.
Managing
Sewage Sludge

    The need for effective sewage
sludge management is continuous
and growing. In the United States,
the quantity of municipal sewage
sludge produced annually has
almost doubled since 1972. Munici-
palities currently generate approxi-
mately 5.3 million dry metric tons
of wastewater sludge per year, or
approximately 47 pounds per
person per year (dry weight basis).
Improper sewage sludge manage-
ment could lead to significant envi-
ronmental degradation of water,
land, and air as well as adverse
human health conditions.
    Prior to the 1987 amendments
to the Clean Water Act, the authori-
ties and regulations related to the
use and disposal of sewage sludge
were fragmented and did not pro-
vide States and municipalities with
adequate guidelines on which to
base sludge management decisions.
There was no single legislative
approach or framework for integrat-
ing the various Federal laws to
ensure that sludge would be used
or disposed of in a consistent or
environmentally acceptable manner.
    Section 406 of the Water Qual-
ity Act of 1987, which amends Sec-
tion 405 of the Clean Water Act, for
the first time sets forth a compre-
hensive program for reducing the
environmental risks and maximizing
the beneficial  uses of sludge. The
program is based on the develop-
ment of technical requirements for
sludge use and disposal and the
implementation of such require-
ments directly through the rule and
through permits.

    In May 1989, EPA promulgated
regulations for including sewage
sludge conditions in NPDES permits
and for issuing sludge-only permits.
These rules also outline the require-
ments for States to seek EPA
approval  to implement the new
statutory requirements.
    EPA is the permitting authority
for sewage sludge since there are
currently no approved State pro-
grams. Initially,  EPA is relying
strongly on the self-implementing
nature of the technical regulations.
In February 1993, EPA amended the
permitting regulations to establish a
tiered permit application schedule.
EPA is focusing its initial permitting
efforts on

•  Sewage sludge incinerators
(which require site-specific pollutant
limits)

•  Facilities posing a threat to
human health and the environment

•  Facilities needing a permit to
promote  beneficial use

•  Facilities with NPDES permits up
for renewal.

    In implementing the new
sewage sludge requirements, EPA is
also focusing on approving State
programs and educating the general
public and the regulated commu-
nity.
    On February 19, 1993, EPA
published the Standards for the Use
or Disposal of Sewage Sludge. This
regulation pertains to land applica-
tion, incineration,  landfilling, and
surface disposal of sewage sludge.
The standards for each use or dis-
posal practice consist of general
requirements, pollutant limits,
management practices, and opera-
tional standards. The final rule also
includes monitoring, recordkeeping,
and reporting requirements.
    Standards apply to publicly and
privately owned treatment works
that generate or treat domestic
sewage sludge, as well as to any
person who uses or disposes of
sewage sludge from such treatment
works. The rule requires compliance
with these standards as expedi-
tiously as possible but  not later than
12 months after the date the rule is
published, or within 24 months of
publication if construction of new
pollution control facilities  is required
to comply with the regulations.
New Initiatives in
Point Source Control


Combined Sewer
Overflow Control

    Currently about 1,100 commu-
nities nationwide use combined
sewer systems, which are designed
to carry sanitary and industrial
wastewater and storm water. These
facilities are mainly located in older
cities in the Northeast, the midwest,
and along the west coast. Com-
bined sewer overflows occur when
the capacity of the combined sewer
system is exceeded during a storm
event. During these storm events,
part of the combined flow in the
collection system is discharged
untreated into receiving waters. The
overflows may contain high levels of
suspended solids, floatables,  heavy
metals, nutrients, bacteria, and
other pollutants. Pollution from
CSOs can pose health risks, degrade

                                              impair the designated use of water
                                              resources.
                                                  EPA published the first National

                                              September  8, 1989, at 54 FR
                                              37370. Although implementation of
                                              the 1989 strategy resulted in some
                                              progress toward controlling CSOs,
                                              EPA determined, in August 1991,
                                              that implementation of the 1989
                                              strategy was not proceeding rapidly
                                              enough.
                                                  During  the summer of 1992,
                                              EPA conducted a negotiated policy
                                              dialogue with key stakeholders.
                                              Based on the negotiated policy dia-

Framework Document was submit-
ted to EPA's Office of Water for
consideration as part of the devel-
opment of a draft CSO policy.
Although the framework was not
the result of consensus among the
negotiating parties, significant
agreement was reached, allowing
OW to use the framework as the
basis to develop a draft CSO policy.
    On  December 22, 1992, the
Assistant Administrator for Water
and the Assistant Administrator for
Enforcement issued a draft CSO
Control Policy (dated December 18,
1992) for comment. The final CSO
Control Policy was published in the
Federal Register on April 19, 1994
(59 FR 18688).
    The main purposes of the Policy
are to elaborate on the 1989
National CSO Control Strategy and
to expedite compliance with the
requirements of the Clean Water
Act.
    The Policy is being developed
to provide guidance to permittees
with CSOs, NPDES authorities, and
State water quality standards
authorities on coordinating the
planning, selection, sizing, and con-
struction of CSO controls that meet
the requirements of the CWA and
to allow for public involvement
during the decisionmaking process.
    The CSO Policy represents a
comprehensive national strategy to
ensure that municipalities, NPDES
permitting authorities, water quality
standards authorities, and the public
engage in a comprehensive and
coordinated planning effort to
achieve cost-effective CSO controls
that ultimately meet appropriate
health and environmental objec-
tives, including compliance with
water quality standards. The  Policy
recognizes the site-specific nature of

                                                             Chapter Fourteen Point Source Control Program   399
CSOs and their impacts and pro-
vides the flexibility necessary to
tailor controls to local situations.
    Contained in the Policy are
provisions for developing appropri-
ate site-specific NPDES permit
requirements for all combined sewer
systems that overflow as a  result of
wet weather events and enforce-
ment initiatives to require the
immediate elimination of overflows
that occur during dry weather and
to ensure that the remaining CWA
requirements are complied with as
soon as practicable. The 1992
Needs Survey modeled the cost of
compliance with the draft  1992
CSO Policy. The Needs Survey esti-
mated that the national capital cost
of CSO corrections will be  $41.2
billion. The modeled estimate
compares to the State-documented
costs  of $22.4 billion for 375 of the
approximately 1,300 CSOs needing
correction.
    EPA is preparing a number of
guidance documents to assist in the
implementation of the final policy.
Specific programmatic areas that
this guidance will address are imple-
menting minimum CSO control
measures by all communities with
CSOs; monitoring and modeling of
combined sewer systems, CSO
discharges, and receiving water
impacts; preparing long-term CSO
control plans by CSO communities;
and drafting NPDES permit require-
ments for CSO discharges  by EPA
and State NPDES permit writers.

NPDES Stormwater
Controls

    Since 1972, State  and  EPA
efforts under the NPDES program
have  traditionally focused on
controlling pollutant discharges
from POTWs and industrial process
wastewaters. As these sources of
pollution came increasingly under
control, the need for controlling
pollutants in stormwater point
source discharges became more
critical to efforts to achieve the
goals of the CWA. As reflected in
this report, stormwater discharges
from a variety of sources, including
storm sewers discharging urban
runoff, construction site runoff, run-
off from resource extraction activi-
ties, and runoff from land disposal
sites, are major sources of use
impairment.
    Section 402(p) of the CWA
amendments of 1987 established a
timetable and framework for EPA to
address stormwater discharges
under the NPDES  program. Section
402(p) required EPA to develop a
two-phase program to control point
source discharges  of storm water.
On November 16, 1990, EPA
promulgated permit application
requirements for the first phase for
discharges from municipal separate
storm sewer systems serving popula-
tions of 100,000 or more and for
stormwater discharges associated
with industrial activity including:

• Manufacturing facilities

• Construction operations or
activities disturbing 5 or more acres

• Hazardous waste treatment,
storage, and  disposal facilities

M Landfills

• POTWs with approved pretreat-
ment programs and/or discharging
over 1 million gallons  per day

                                    most part, by October 1, 1993.
                                        For the second phase, EPA
                                    prepared a study that identified
                                    potential stormwater discharges,
                                    not regulated under Phase I, to be
                                    controlled to protect water quality.

                                    Congress in March 1995. The study
                                    identifies the nature and extent of
                                    pollutants in these discharges and
                                    proposes one possible option for
                                    controlling these  discharges.
                                       To explore additional options
                                    for a Phase II stormwater program,
                                    EPA convened a Federal Advisory

                                    by December 1996. EPA is required
                                    under a consent decree to propose
regulations by September 1, 1997,
and finalize regulations by March 1,
1999.

Pollution Prevention

    EPA has established an Office of
Pollution Prevention that works with
other program offices to improve
pollution prevention activities within
the Agency. For example, an
Agency pollution prevention policy
has been developed, and a strategy
to address pollution prevention in
manufacturing and chemical use has
been drafted. Future strategies will
focus on  the municipal water and
wastewater, agricultural,  energy,
and transportation sectors. A sub-
committee comprising representa-
tives from EPA Headquarters and
Regions has been formed to
develop an Agency-wide training
strategy to ensure that pollution
prevention concepts are integrated
into all Agency activities.
    In terms of the point source
control program, the Agency's draft
pollution prevention strategy recog-
nizes the importance of permitting
and enforcement activities and will
continue  support for a strong
program  in these areas. Training is
being provided to familiarize NPDES
permit writers with  pollution
prevention opportunities, how their
permit decisions can affect other
media, and how to effectively
communicate the concept of
pollution  prevention to industrial
managers.

Nonpoint  Source
Control  Program
Background
    Nonpoint source pollution
generally results from land runoff,
atmospheric deposition, drainage,
or seepage of contaminants. Major
sources of nonpoint pollution
include agricultural runoff, runoff
from urban areas, and runoff from
silvicultural operations, Siltation and
nutrients are the pollutants respon-
sible for most of the nonpoint
source impacts to the Nation's sur-
face waters. These diffuse sources
are  often harder to identify, isolate,
and control than traditional point
sources. As a result, from 1972 to
1987, EPA and the States placed
primary focus on addressing the
obvious problems due to municipal
and industrial discharges: issuing
permits for point source discharges,
then inspecting, monitoring, and
enforcing those permits to ensure
that point sources met the Clean
Water Act requirements.
    Sections 208 and 303(e) of the
Clean Water Act of 1972 established
the initial framework for addressing
nonpoint sources of pollution. States
and local planning agencies ana-
lyzed the extent of NPS pollution
and developed water quality
management programs to control it
with funds provided by EPA under
Section 208. Best management
practices were evaluated, assess-
ment models and methods were
developed, and other types of
technical assistance were made
available to State and local water
quality managers.

The National Section
319 Program

   In 1987, Congress enacted
Section 319 of the Clean Water Act,
which established a national pro-
gram to control nonpoint sources of
water pollution. Section 319 created
a three-stage national program to
be implemented by the States with
Federal approval and assistance.
States were to address nonpoint
source pollution by (1) developing
nonpoint source assessment reports,
(2) adopting nonpoint source man-
agement programs, and (3) imple-
menting the management programs
over a multiyear timeframe.
   All States and Territories now
have EPA-approved nonpoint source
assessments. EPA has also fully
approved 55 State nonpoint source
management programs and has
approved the high-priority portions
of all remaining State management
programs.
    Section 319 also authorizes EPA
to issue annual grants to States to
assist them in implementing their
EPA-approved programs. From FY90
through FY95, Congress appropri-
ated approximately $372 million for
Section 319 assistance. EPA first

-------
404   Chapter Fifteen  Nonpoint Source Control Program
                           t
issued guidance on the award and
management of Section 319 funds
in February 1991 following exten-
sive public comment. In June 1993
the guidance was updated to incor-
porate suggestions from EPA
Regions and a workgroup of State
program managers and lessons
learned during  3 years of awarding
and managing  Section 319 grants.
The guidance encourages States to
focus Section 319 funds on high-
priority activities including:

• Controlling particularly difficult
or serious nonpoint source prob-
lems, including, but not limited to,
problems resulting from mining
activities

• Implementing innovative
methods or practices for controlling
nonpoint sources of pollution,
including regulatory (e.g., enforce-
ment) programs

• Controlling interstate nonpoint
source pollution problems

• Carrying out ground water qual-
ity protection activities that are part
of a comprehensive nonpoint source
pollution control program

• Addressing nationally significant,
high-risk nonpoint source problems
and focusing implementation
activities in priority watershed
or ground water areas

• Comprehensively integrating
existing programs to  control
nonpoint source pollution

• Providing for monitoring and
evaluation of program effectiveness,
including using water quality moni-
toring protocols
• Demonstrating a long-term
commitment to building the
institutions necessary for effective
nonpoint source management

• Emphasizing pollution prevention
mechanisms

• Protecting particularly sensitive
and ecologically significant waters
(e.g., wetlands, estuaries, wild and
scenic rivers, exceptional fisheries)

• Promoting comprehensive
watershed management

• Providing for the use of
antidegradation provisions and
other measures necessary to ensure
that population growth, new devel-
opment, and new or expanded
economic activity do not result in
impairment of high-quality waters
and waters currently meeting water
quality standards

• Addressing urban storm water
that is not subject to NPDES permit
requirements

• Promoting implementation of
coastal nonpoint source manage-
ment measures developed pursuant
to Section 6217(g) of the Coastal
Zone  Act Reauthorization Amend-
ments of 1990.

    Roughly half of each State's
annual award supports  statewide
program activity (staffing, public
education and outreach, technical
assistance) and  half supports specific
projects to prevent or reduce
nonpoint source pollution at the
watershed level.
    EPA and the States  have
recently begun  a process to exam-
ine and  improve national and State

                                                           Chapter Fifteen  Nonpoint Source Control Program  405
nonpoint source programs to
enhance program processes as well
as substantially improve water qual-
ity. As a first step, EPA, in close
cooperation with the States, devel-
oped additional guidance in April
1995 that provides greater flexibility
to the States for strengthening ancl
implementing their nonpoint source
management programs.
    Funding under Section 319 is
also available to American Indian
Tribes with approved nonpoint
source assessment and management
programs. In September 1994, EPA
issued A Tribal Guide to the Section
319(h) Nonpoint Source Grant Pro-
gram to provide Tribes with an
overview of the Section 319(h)
grant process and to assist Tribes in
working with EPA Regions to meet
the basic requirements for grant
eligibility.

Section 319 National
Monitoring Program

    EPA developed the Section 319
National Monitoring Program to
improve technical understanding  of
nonpoint pollution and the effec-
tiveness of various nonpoint source
control technologies. This program
selects watershed  projects that con-
sistently monitor water quality and
land management with standard-
ized protocols for 6 to 10 years. As
of June 1995, EPA had approved
and funded 11  projects in the States
of Vermont, Wisconsin, Pennsyl-
vania, North Carolina, Michigan,
Iowa, Nebraska, Arizona, Illinois,
Washington, and  California. EPA has
also funded a pilot ground water
demonstration project in Idaho.
Several of these projects are summa-
rized here.
    The Lake Champlain, Vermont,
project is a paired watershed study
that will be carried out coopera-
tively by the University of Vermont
and the Vermont Department of
Environmental Conservation. The
study is designed to examine the
effectiveness of best management
practices installed  in two treatment
watersheds to control sediment,
nutrients, and bacteria contributions
from livestock. The study calls for
2 years of pretreatment data collec-
tion, 1  year of monitoring during
implementation of nonpoint con-
trols, and 3 years of postimplemen-
tation monitoring.  Data will be col-
lected on a number of parameters,
including total suspended solids,
total phosphorus,  total Kjeldahl
nitrogen, fecal coliform, water tem-
perature, dissolved oxygen,  conduc-
tivity, fish, and macroirivertebrates.
Land use and agricultural activity
will also be monitored intensively in
each watershed.
    Otter Creek, Wisconsin, is a
low-gradient warm water stream  in
the Sheboygan River watershed,
which drains to Lake Michigan.
Land use in the watershed is pri-
marily agricultural. Data collected in
1992 indicated that the stream is
highly degraded, impacted  by
nonpoint sources from barnyards,
upland erosion, manure spreading,
streambank erosion, and pastures
along the creek. Habitat degrada-
tion—e.g., lack of cover, disturbed
banks,  and an absence of pools—
also contributes to the stream's
problems. The project, which
includes a paired watershed and
upstream-downstream studies, will
encompass the monitoring  of
chemical, physical, and biological
parameters and the implementation
of nonpoint source controls. A

                                     industrial or urban areas. Land use
                                     consists predominantly of cropland
                                     (corn, oats, and alfalfa),  pasture,
                                     and forest. Sediment is the major
                                     pollutant but nutrients, pesticides,
                                     and animal waste are also of con-
                                     cern. The USDA will provide techni-
                                     cal assistance, cost sharing, and
                                     educational programs to assist agri-
                                     cultural producers in  implementing
                                     nonpoint source control  measures
                                     such  as sediment control, stream
                                     corridor management improve-
                                     ments, and animal waste manage-
                                     ment systems. Land treatment appli-
                                     cation will be coordinated with
                                     water quality monitoring.
                                        The Bloody Run watershed  (a
                                     neighboring watershed of approxi-
                                     mately the same size) serves as the
paired comparison watershed, or
control site. Primary monitoring sites
were established on both water-
sheds to measure discharge and
suspended sediment. Other sites on
both creeks will be sampled for
chemical and physical water quality
variables on a weekly to monthly
basis. A habitat assessment will be
conducted along stretches of both
stream corridors annually, fishing
surveys will  be conducted annually,
and biomonitoring of macro-
invertebrates will be performed
bimonthly.
    The Long Creek project is
located in south-central North Caro-
lina. The watershed contains mixed
agricultural and urban/industrial
land use. Long Creek serves as the
primary water supply for Bessemer
City (population 5,000). Sediment
from eroding cropland is the major
problem in the  upper third of the
watershed (above the water supply
intake). Long Creek is impaired
mainly by bacteria and nutrients
from urban  areas and animal hold-
ing facilities below the intake. Pro-
posed nonpoint controls include
implementing the land use restric-
tions of the  State watershed protec-
tion law for areas above the water
supply intake, erosion  and sediment
controls,  animal waste manage-
ment, and livestock exclusion. Water
quality monitoring will include a
single station before and after
improved erosion control  near the
water intake, an upstream/down-
stream design on the Creek above
and below the dairy farm, and a
paired watershed design at a crop-
land runoff site  on  the dairy. Con-
tinuous and grab samples will be
collected at  various sites to provide
the data needed to assess the effec-
tiveness of the nonpoint controls.

    The Morro Bay watershed,
located on the central coast of
California, is an important biological
and economic resource. Morro  Bay
estuary is considered to be one of
the least altered estuaries on the
California coast However, heavy
development activities have resulted
in an increase of nonpoint source
pollutants entering the watershed.
The nonpoint source pollutants of
primary concern include sediment,
bacteria, metals, nutrients, and  or-
ganic chemicals. At present rates of
sedimentation, Morro Bay could be
lost as an open water estuary within
300 years.  Not only has the acceler-
ated sedimentation rate negatively
impacted fish  and macroinverte-
brate species,  it has also resulted in
significant economic losses to the
oyster industry. This project was
developed  to  characterize the sedi-
mentation  rate and other water
quality conditions in one of the
Bay's tributaries, evaluate the effec-
tiveness of several best management
practices in improving water and
habitat quality, and evaluate the
overall water quality at selected sites
within the watershed.

Reports on Section
319 Activities	

    As required by Congress, EPA
published a report about Section
319, Managing Nonpoint Source
Pollution, in 1992. This report
described the Section 319 Program,
summarized the State nonpoint
source assessment reports submitted
to EPA, and described Regional and
State activities implemented to  con-
trol nonpoint  source pollution.  In
1994, EPA published Section 3T9(h)
Success Stories, which provided
examples of successful solutions to
nonpoint source pollution problems
from States, Territories, and Tribes.
The described projects include infor-
mation and education programs,
streambank stabilization projects,
animal waste management projects,
and urban runoff projects.

Nonpoint Source
Management
Programs and
Implementation

    The States, local governments,
community groups, and EPA
Regions have initiated many innova-
tive projects across the Nation to
manage nonpoint source pollution
problems. The projects described  in
this section exemplify the diversity
of approaches that have been
applied to NPS pollution prevention
and control. In some cases,  preven-
tion or control is only beginning.  In
other situations, prevention  and/or
control measures have been in place
long enough to show significant
results. For additional information

                                    volunteers to sample water quality
                                    before, during, and after rainstorms
                                    to determine the extent and sources
                                    of bacterial contamination. The
                                    volunteer monitors found that bac-
                                    terial pollution, which was particu-
                                    larly widespread after rainfalls, was
                                    caused primarily by failing septic
                                    systems,  stormwater discharges,
                                    illegal septic tie-ins, and roosting
                                    birds.
                                        Funding for the monitoring was
                                    provided by a Section 319 grant of
                                    approximately $35,000 and other
                                    private funding sources. As part of
                                    their project, the group worked
                                    with individual polluters to correct
                                    situations and with the local boards
                                    of health to enforce local  ordi-
                                    nances. As a result, the volunteers
                                    made great progress in cleaning up
                                    both the North and South Rivers. In

                                    chose to focus on preventing new
                                    development from  causing further
                                    problems. With approximately
                                    $285,000 in Section 319 funds over
                                    several years, the State has estab-

                                        The 319 grants have provided
                                    funding for a number of projects.
These projects include reprinting an
urban erosion and sediment control
manual, which contains standards
and specifications for erosion and
sediment control measures common

Mammoth Cave
National Park, Kentucky

    The Mammoth Cave National
Park is a major tourist site, attracting
over 2 million visitors annually.
However, the unusual geology that
attracts visitors to the park also
makes it particularly vulnerable to
poor water quality. Instead of flow-
ing into surface streams, rain falling
within the karst (limestone forma-
tion) sinkhole plain in and around
the park flows  into  some 15,000
active sinkholes. The water travels
through underground streams and
caves, including Mammoth Cave,
before emerging as spring water in
the Green River. In  the past several
years, the State has become   :
concerned that water quality
degradation from intensive agricul-
ture (due to excessive nutrients and
bacterial contamination) could seri-
ously affect the area.

    The Mammoth Cave/Karst Area
Water Quality Project was designed
to reduce pollution in the park area
and the surrounding karst sinkhole
plain. The Kentucky Division of
Water used part of its Section 319
grant to support the project's water
quality monitoring, technical assis-
tance, and installation of nonpoint
source  controls on demonstration
farms in fiscal years 1991 through
1993. Activities were coordinated by
a technical advisory committee
formed with representatives from a
number of State government agen-
cies, citizens, and land users. Other
agencies involved with the project
include ASCS, SCS, National Park
Service, and Tennessee Valley
Authority.

Nolichucky River
Watershed, Tennessee

    Concern over nonpoint source
water pollution from livestock pro-
duction prompted Tennessee to
target five subwatersheds in the
Nolichucky River watershed. Animal
waste systems were installed to
store animal wastes and manure,
which farmers later use to fertilize
crops. A Section 319 grant of
$58,000 provided assistance for
installing best management prac-
tices in the watershed and also
allowed project staff to monitor the
water quality to measure the effec-
tiveness of management practices.
A year after installation, the Tennes-
see Department of Health found
statistically valid improvements in
benthic habitat in two watersheds,
Nanticoke Watershed,
Delaware

    Trap Pond in the Nanticoke
watershed is the recreational focus
for Trap Pond State Park. Increasing
bacterial contamination and symp-
toms of accelerated eutrophication
and  algal blooms were evident as
water quality in the lake became
degraded. Two probable causes
were identified: a direct discharge
from an underground septic system
and  livestock with direct access to
the stream. The problem with the
leaking septic system  was corrected
and  a Section 319 grant of $84,000
was  awarded to implement animal
waste management systems and
nutrient management plans on
farms throughout the watershed. All
of the producers fenced livestock
out of streams and some 98% of
the producers installed manure stor-
age facilities, buffer strips, and other
best management practices.

West Lake Reservoir,
Iowa

    West Lake is the surface reser-
voir for Osceola and Woodburn,
cities located in south-central Iowa.
The  lake was impaired by sediment,
pesticides, and nutrients primarily
from row crop agriculture. A Section
319  grant of nearly $170,000 was
awarded for program staffing and
implementing best management
practices. Best management prac-
tices such as no-till and integrated
crop management reduced sedi-
ment delivery and herbicide levels
to the lake. In addition, a voluntary
atrazine ban assisted in the  lake's
recovery.

                                        The Big Sioux Aquifer and other
                                    smaller surface aquifers lie under
                                    approximately 1,000 square miles of
                                    eastern South Dakota. The aquifers
                                    supply drinking water to about one-
                                    third of the State's population.
                                    Although no widespread pollution
                                    problem existed, studies had uncov-
                                    ered isolated cases of nitrate con-

                                    (EDWDD) began the Big Sioux
                                    Aquifer Protection Project. The goal
                                    of the project was to protect the Big
                                    Sioux Aquifer and other sensitive
                                    aquifers from contamination

                                    zoning ordinances.
                                        As part of the project, the
                                    EDWDD also identified shallow aqui-

                                    rural areas about threats to their
                                    domestic wells. The group also
                                    developed a model ground water

                                    1993, two cities  and nine counties
                                    had adopted similar ordinances.
Pearl  Harbor Bay
Watershed, Hawaii

    Soil  erosion and heavy siltation
in the East Loch of Pearl Harbor
prompted the U.S. Navy to request
that the South Oahu Soil and Water
Conservation District hold an  inter-
agency meeting to explore  ways to
prevent  soil erosion from all land
uses in Hawaii. As a result of the
meeting, the Pearl Harbor Estuary
Program Interagency Committee
(PHEPIC) was formed; its member-
ship consisted of 17 agencies and
groups.
    Through the use of Section 319
funds in concert with  other monies,
PHEPIC  began a public education
and information campaign. As part
of these efforts, a storm drain sten-
ciling project was  undertaken to
raise public awareness about how
storm drains are connected directly
to streams and the ocean. Section
319 funds were also used in coop-
eration with Hawaii's  Department  of
Transportation and Department of
Highways in a demonstration
project to restore a severely eroded
site adjacent to the Pearl Country
Club. This project involved  revegeta-
tion of eroding roadside cuts with
drought-tolerant, low-maintenance
vegetation.

Funding for Nonpoint
Source Control

    In addition to Section 319
funds, several States have taken
advantage of State Revolving Funds
to provide loans to finance
nonpoint source and  other water
pollution control programs. SRFs

                                                           Chapter Fifteen Nonpoint Source Control Program  411
were originally established to assist
States in upgrading their sewage
treatment systems, but the 1987
amendments to the Clean Water
Act provide States with the opportu-
nity to use these funds for nonpoint
source control. SRF loans are  par-
ticularly suitable for funding struc-
tural BMP construction, such  as
stormwater detention ponds and
manure storage structures.
    Numerous States, including
Washington, California, Delaware,
and Ohio, are using SRF loans to
fund a wide variety of nonpoint
programs. Approved projects will
retrofit failed septic tanks, construct
stormwater management structures,
remediate leaking  underground
storage tanks, and build poultry
composting facilities. As States meet
sewage treatment system upgrade
requirements, SRF funds will
become increasingly available to
address nonpoint source problems.

Coastal Nonpoint Pollution
Control Program

    As this report shows, serious
water quality problems associated
with nonpoint pollution still remain.
The shift in population toward the
coasts and associated development
pressures moved Congress to pro-
vide States with new information
and tools to achieve more effective
protection of coastal waters from
nonpoint pollutants. Congress
enacted the Coastal Zone Act Reau-
thorization Amendments (CZARA) of
1990, which established under Sec-
tion 6217 a new coastal nonpoint
source pollution control program to
be incorporated into both State
Section 319 (CWA) programs and
State Coastal Zone Management
Act (CZMA) programs. NOAA
administers the CZMA and EPA
administers Section 319, and the
two agencies have worked coopera-
tively toward implementing Section
6217.
    Section 6217 requires that
States with federally approved
coastal zone management programs
develop and implement Coastal
Nonpoint Pollution Control
Programs to ensure protection and
restoration of coastal waters.
Twenty-nine States and Territories,
including several Great Lakes States,
currently have approved coastal
zone management programs.
    Under CZARA, State Coastal
Nonpoint Pollution Control
Programs must provide for imple-
mentation of (1) management
measures specified by  EPA in the
national technical guidance, and (2)
additional, more stringent measures
developed by each State as neces-
sary to attain and maintain water
quality standards where the baseline
measures do not accomplish this

                                     objective. The CZARA further
                                     provides that States' Coastal Zone
                                     Management Programs must
                                     contain enforceable policies and
                                     mechanisms to ensure implementa-
                                     tion of the baseline and additional
                                     management measures.
                                         EPA issued final technical guid-
                                     ance in January 1993  titled Guidance
                                     Specifying Management Measures for
                                     Sources of Nonpoint Pollution in
                                     Coastal Waters. This guidance speci-
                                     fies management measures for five
                                     major categories of nonpoint pollu-
                                     tion: agricultural runoff, urban  run-
                                     off, silvicultural runoff, hydromodi-
                                     fication, and marinas and recrea-
                                     tional boating. The guidance also
                                     describes specific practices that may
                                     be used to achieve the level of
                                     prevention or control  specified in
                                     the management measures.
                                         EPA and NOAA have also issued
                                     joint program guidance to  assist the
                                     States in developing coastal non-
                                     point pollution control programs.
                                     Final program guidance was issued
                                     in January 1993. The program  guid-
                                     ance addresses issues  related to
                                     development by the States of
coastal nonpoint programs for joint
approval by NOAA and EPA. In
addition, NOAA and EPA have
recently taken steps to provide
States and Territories significant
additional time and flexibility in
developing and implementing their
coastal nonpoint programs. The
States must submit coastal nonpoint
control programs to NOAA and EPA
within 30 months of issuance of the
management measures guidelines
Ouly 1995). NOAA and EPA then
have 6 months to complete their
review of the coastal nonpoint
programs.
    Between November 1993 and
June 1995, NOAA and EPA met
with over 20 coastal States and
Territories to review their progress in
developing coastal  nonpoint pro-
grams. These "threshold reviews"
have assisted States in  identifying
where additional work may be
necessary for meeting the require-
ments of Section 6217 and have
enhanced  NOAA's and EPA's  under-
standing of the variety of State pro-
grams and approaches for control-
ling nonpoint pollution.

 Protecting Lakes
 Background
    Since the early 1980s, and espe-
 cially with the 1987 CWA reauthori-
 zation, nonpoint source impacts and
 multimedia issues such as acid rain
 have received increased attention in
 Federal regulations. Addressing
 these more holistic concerns has led
 to lake programs and projects that
 are closely coordinated with other
 Federal, State, Tribal, or local initia-
 tives.
    EPA encouraged States to
 develop and implement lake
 projects on a watershed basis. This
 ensures that restoration activities are
 long term and comprehensive.
 Under this approach, nonpoint
 source control, ground water pro-
 tection, water quality permitting,
 estuarine protection and cleanup,
 and wetlands protection issues can
 be addressed in a holistic manner.


 Biennial Lake
Assessment

    Under the 1987 CWA reauthori-
zation, several new provisions were
added to the original provisions
encouraging States to identify their
publicly owned lakes and classify
them according to their eutrophic
condition. Lake assessment informa-
tion was to be updated in a fashipn
analogous to other State water qual-
ity assessments and reported bien-
nially following the same timelines
as the Section 305(b) reports. Most
 States now include their Section
 314 lake assessments in their 305(b)
 reports. Recent procedural changes
 to the regulations governing the
 Water Quality Planning and Man-
 agement Program (FRL-3979-8,
 Federal Register, Vol. 57, No. 143,
 Friday, July 24, 1992) now clearly
 specify that lake assessment mate-
 rials should be part of the 305(b)
 report submittals.


 Publicly Owned Lakes

    Section 314 requires that
 States report on their "significant
 publicly owned lakes"-leaving the
 definition of "significant" up to the
 individual State. States have defined
 significant publicly owned lakes with
 varied physical and legal criteria, but
 most States have included minimum
 size criteria and recreational use
 caveats in their definitions.  For
 example, New Hampshire's defini-
 tion  of significant publicly owned
 lakes is "any freshwater lake or
 pond that has a surface area of 10
 or more acres, is not private, and
 does not prohibit recreational activ-
 ity."  As a general rule of thumb,
 most States settle on a set of
 significant lakes ranging in number
from less than a hundred (for
smaller States) to a few hundred
 lakes in larger western or midwest-
ern States. However, some States
classify all of their lakes as significant
publicly owned lakes.
   The States typically focus on
highly utilized lakes because local

-------
416  Chapter Sixteen Protecting Lakes

citizens and governments are more
likely to assist in control and restora-
tion projects and assume ongoing
stewardship for these lakes and their
watersheds. High-value lakes attract
a diverse group of local stakeholders
to anchor the activities associated
with lake projects.


Lake Beneficial
Use Impairments
and Trends  	

    The 1987 CWA Amendments
contain many provisions encourag-
ing a water-quality-based approach
to pollution assessment,  planning,
and management activities. Biennial
lake assessments are now expected
to make use of available information
to document publicly owned lakes
where uses are known to be
impaired as well as lakes where
there is evidence of water quality
deterioration. Many States  use EPA's
Waterbody System to produce sum-
mary tables that categorize lake
acreages by use  attainment (e.g.,
fully supporting, threatened, par-
tially supporting, or not supporting).
Summary tables are also generally
provided that categorize the major
causes and sources of pollution.
However, many  States still lack
water quality standards specific to
lakes, thereby complicating the
process of lake water quality assess-
ment.
    Under the 305(b) reporting
 process of the Clean Water Act,
 States are encouraged to provide
waterbody-specific summaries of
various public health and aquatic
 life concerns. This can include infor-
 mation on fishing advisories, fish
 kills,  sites with sediment contamina-
 tion, restrictions on surface water
drinking supplies, bathing area
restrictions, and incidents of
waterborne diseases. This informa-
tion is reported for all waterbody
types, including lakes. Perhaps the
most common concern reported is
the contamination of fish tissue by
toxicants, leading to fish consump-
tion warnings or advisories.
Although this information is cer-
tainly valuable, many States have
difficulty relating fish consumption
advisory data clearly to  provisions in
their own water quality standards.
For instance, a public health agency
may declare a fish consumption
advisory for a lake based on trigger
values for some toxicant (for
instance, mercury) that are not tied
to numeric standards criteria for any
particular beneficial use. States are
making progress in achieving consis-
tency in their reporting of concerns
such as fish consumption advisories
in relation to their reporting State
beneficial use attainment status.
However, results for these two types
of assessment information may
require careful scrutiny to avoid
misinterpretation.

Continued
 Importance of
Trophic Status
 Classifications

    Reporting on trophic conditions
 is still a central feature  under the
 1987 CWA reauthorization, and
 most States still use ranking systems
 based primarily on trophic status
 information as the foundation for
 protecting lakes.
    Trophic condition is a character-
 ization of a lake's biological produc-
 tivity based on the availability of

-------
                                                                             Chapter Sixteen Protecting Lakes  417
 plant nutrients. Commonly accepted
 systems for describing trophic status
 recognize a range of conditions,
 with oligotrophic indicating the
 least biologically productive lakes
 and eutrophic indicating signifi-
 cantly higher levels of productivity.
 For national reporting purposes, the
 following categories are recom-
 mended: oligotrophic, mesotrophic,
 eutrophic, and hypereutrophic. For
 those lakes showing exceptionally
 high levels of organic materials and
 associated reduced pH levels, humic
 substances, and natural color, the
 term dystrophic is used.
    Both natural lakes and
 manmade reservoirs usually show
 shifts in their trophic condition  over
 time  (Figure 16-1).  It is important,
 however, to distinguish between
 natural eutrophication, the process
 by which lakes gradually evolve and
 age, and cultural eutrophication,
 which can be defined as the cultur-
 ally induced rapid acceleration of
 the natural eutrophication process.
 The natural eutrophication process
 ordinarily may take centuries, as
 lakes  naturally shift from an olig-
 otrophic to a more eutrophic status.
 Sedimentation processes will eventu-
 ally lead to trophic shifts in
 manmade  impoundments, generally
 in a much  shorter time period than
for natural lakes. Reservoirs,  there-
fore, have effective lives ranging
from a few decades to perhaps a
few hundred years. Newly
impounded reservoirs may initially
be characterized as eutrophic
because of the decay of woody
debris but may shift to a less
eutrophic status for most of the
impoundment's useful life. The cul-
tural eutrophication  process, for
either natural lakes or reservoirs,
involves the rapid (over a matter of

of the waterbody because of
human-induced external nutrient
and sediment inputs.
     Because there is an inherent
 dynamic aspect to the trophic bal-
  ances in lakes, caution must be
  exercised  in characterizing any-
   thing other than an oligotrophic
   condition as undesirable. On the
    other  hand, many types of an-
     thropogenic stresses may result
     in rapid trophic status shifts. If
     a lake  shows rapid progression
     toward a state exhibiting
     excessive algae growth, rapid
organic and inorganic sedimenta-
tion, and seasonal or diurnal dis-
solved oxygen deficiencies leading
to obnoxious odors, fish kills, or a
shift in the  composition of aquatic
life forms to less desirable forms,
then an advanced stage of cultural
eutrophication is very likely. Most
commonly, large external inputs of
nutrients from point and/or
nonpoint sources leads to  an unde-
sirable stage of cultural eutrophica-
tion. Restoring a lake to a  more
desirable trophic condition will then
 require reductions in the external
 nutrient loading  and possibly in-lake
 restoration  activities to mitigate the
 impacts of  previous pollution inputs.
     When evidence suggests that
 pollution factors are driving the lake
 to a more eutrophic state, a State
 will likely rate that waterbody as a
 relatively high priority candidate for
 management attention. Other types
 of information are helpful  in priori-
 tizing a public lake's management
 needs (e.g., documentation of
 trends and consideration of factors
 such as acidity or toxics),  but
 trophic status assessments are still
 the backbone of the classification
 systems used in  most States.

discretion when the only measure-
ment for a TSI comes from Secchi
disk readings. Without other infor-
mation about a  lake, and especially
reservoirs where reductions in trans-
parency may be due more to sus-
pended inorganic particles than to
blooms of algae or due to location
of the sampling  site or other factors,
a Secchi measurement may give
false signals as to the degree of
biological productivity.
    States are increasingly using
TSIs based on phosphorus or, where
possible, chlorophyll a measure-
ments. However, light transparency
data may still be useful, especially
when correlated with visual observa-
tions of color. Even if loss of trans-
parency is due more to turbidity
and suspended solids than to algae,
it may indicate unwanted  sedimen-.
tation  problems  affecting trophic
balances and a lake's recreation
value. When available, long time
series of Secchi depth readings are
often a good tool for trend analysis.
Secchi readings, often collected by
volunteer monitoring groups, can
therefore still play an important role
in  a State's lake  monitoring pro-
grams; but, for the highest quality
characterization  of lake trophic
status, measurements more closely
related to biological process and
food chain dynamics are preferred.
    Many States are evaluating dif-
ferent ways to supplement methods
such as Carlson TSIs to make cost-
effective characterizations of trophic
status. For instance, using  a broader
range of parameters, there are other
standard indexes that may prove
helpful; many of these indexes were
originally developed in the 1970s as
part of EPA's pioneering National
Eutrophication Survey. Whatever the
general form in a TSI formula, it is
 highly desirable to regionalize the
 system to conditions found in a
 specific State or ecoregion. States
 such as North Carolina have devel-
 oped regional indices, and Oregon,
 Minnesota, and Arkansas have
 applied ecoregion concepts in inter-
 preting their lake monitoring data.
 Oklahoma and Texas are also evalu-
 ating different methods to assess
 trophic status in reservoirs.
    Many States are now exploring
 ways to develop biologically based
 (bioassessment) techniques. For
 instance, the presence or absence of
 certain types of zooplankton is often
 strongly correlated with a well-
 balanced biological community.
 Diverse and healthy populations of
 algae-consuming  zooplanktons such
 as Daphnia pulex can  help prevent
 the buildup of objectionable algal
 biomass even in lakes showing
 app'reciable  nutrient inputs. Shifts in
 the populations of game fish or
 plankton-eating forage fish can
 sometimes lead to a decimation of
 the zooplankton,  allowing algae to
 flourish. Biomanipulation techniques
 aimed at increasing the  populations
 of top predator fishes or reducing
 the populations of forage fishes can
 often correct the trophic imbal-
 ances. Bioassessments of the
 plankton communities or the fish
 populations  can therefore indicate
 overall trophic status. Other tech-
 niques being explored look at
 benthos or macrophytes in lake
 littoral areas. These  techniques can
 be valuable supplements to the
 more traditional Carlson TSIs that
focus on algal standing crop, nutri-
 ents, or transparency parameters.
    In  1994, 41 States reported
that 18% of the 9,735 lakes
they assessed for trophic status
were oligotrophic, 37% were

mesotrophic, 36% were eutrophic,
6% were hypereutrophic, and 3%
were dystrophic (Figure 16-2). This
information may be somewhat
biased, as States often assess lakes in
response to a problem  or public
complaint or because of their easy
accessibility. It is likely that more
remote lakes-which are probably
less impaired-are  underrepresented
in these assessments.


Lake Acidity Impacts

    During the 1980s,  considerable
national attention focused on how
pollution can lower the pH of
receiving waters, especially lakes.
Acidity can pose a direct threat to
aquatic life and lake recreational
amenities. Major potential sources
include atmospheric deposition and
acid mine drainage. EPA coordi-
nated a major multi-agency study
called the National Acid Precipita-
tion Assessment Program (NAPAP)
to study acid deposition. A wealth
of data were collected  on many
lakes and stream systems under
NAPAP. NAPAP also provided
insights into promising monitoring
designs to document receiving
waters with actual acidity problems
or sensitivities to potential acid
impacts.
    NAPAP concluded  that the inci-
dence of serious acidification prob-
lems was far more limited than
originally feared, and this Federal
hypothesis seems to be reflected in
evidence reported by the States in
their lake water quality assessments.
At least for significant publicly
owned lakes, the  Adirondack^ area
of New York emerges as the only
region showing appreciable num-
bers of public lakes  with significant
acidification damage.
    In addition to impacts from
acidity per se, low pH conditions
can accentuate impacts from a vari-
ety of toxicants. For instance, many
metals show increased availability as
the pH drops and, where acid mine
drainage is involved, the pollutant
source for the acidity may also be a
source of toxicants. Acidity may also
accentuate the impacts on aquatic
organisms of a variety of toxics and
may often increase bioaccumulation
or biomagnification  processes that
move toxicants into the tissues of
fish and thus into the food chain.   ,
Toxic accumulations in sediment
also complicate the  use of lake
restoration techniques such as
dredging.
    Acidic lakes are  generally found
in areas where watershed soils have
limited buffering capabilities. Acid
rain or acid mine drainage can then
depress a lake's pH levels to a point
at which many forms of aquatic
life are stressed or eliminated.
Table 16-1 summarizes some of
the common biological effects at
progressively lower pH ranges.
    In the eastern United States,
such areas as southern New Jersey
have been shown to have limited
natural buffering capacity, making
many lakes potentially vulnerable to
acid deposition impacts. In addition
to lakes, some States are concerned
about acidity impacts on high-gradi-
ent trout streams. Where the acidity
concerns affect whole watersheds,
this encourages a search for
mitigation techniques that could
benefit both lakes and streams.  New
York has undertaken some innova-
tive demonstration projects aimed
at liming whole watershed areas
instead  of the more traditional
strategy of liming just the lakes.

    States have documented areas
where local geological and soil fac-
tors may render lakes deficient in
natural buffering capacity and there-
fore vulnerable to acidity stress.
Such sensitive areas seem quite
prevalent in high-altitude glacial
lakes in mountainous areas in the
Rockies and several western States.
A major concern here is low pH
water introduced from snowpack
meltwater. Many of these  high-
altitude lakes may show a  seasonal
pulse of low pH inflows, usually
during the Spring. The ecological
consequences are not entirely clear,
and States such as Colorado and
Washington will continue to study
this episodic phenomenon.
    Serious impacts from acid mine
drainage also seem relatively rare.
No State has found clear documen-
tation of acidity impacts related to
active mining activities. However,
there is some concern about aban-
doned mine workings. At least one
State, Oklahoma, is undertaking a
study on a portion of the Eufaula
Reservoir that lies in a region with a
long history of surface and hard
rock coal mining activities.
    In  light of these concerns, Con-
gress added provisions for  State lake
assessment reporting to document
known instances of acidity or toxics
impact to public lakes in the 1987
CWA reauthorization. If such issues
are related to actual impairments or
pose real degradation threats, States
are encouraged to  document meth-
ods and procedures that could
mitigate the harmful effects of high
acidity or toxic metals and other
toxic substances.
    In 1994, 26 States reported
that, of the 5,933 lakes assessed for
acidity, 9% exhibited acidity and
16% were threatened by acidity.
 Over half of
 these lakes
 exhibiting acid-
 ity and roughly
 one-quarter of
 the lakes threat-
 ened by acidity
 were in New
 York. Very little
 information was
 provided by
 States regarding
 the sources of acidity to impacted
 or threatened lakes.

 Toxic Effects  on Lakes

    In the 1987 CWA reauthoriza-
 tion, there was an expectation that
 if toxics concerns were encountered
 in lakes, they might be tied to an
 anticipated widespread incidence of
 acidity problems. As  discussed
 above, evidence submitted by the
 States and from  the Federal NAPAP
 investigations suggests that lake
 acidity problems are  much rarer
 than anticipated. Toxics concerns
 States have submitted,, therefore,
 are generally not related to
 depressed pH levels.
    Many States do report serious
 toxics concerns,  with the most com-
 mon centering on fish consumption
 advisories. Most  States maintain
 programs  to sample fish tissues from
 their major public lakes. These
 collections also generally involve
 sampling of ambient water and
sediments. Rarely do  ambient water
 levels exceed detection limits for
 heavy metals or common pesticides.
 For sediments and fish flesh, how-
ever, virtually all  States have at least
one public lake at which elevated
 levels of some toxicant have been
documented. Any exceedances of

                                      such standards are not well-defined,
                                      the information may show up only
                                      in the 305(b) sections dealing with
                                      public health/aquatic life concerns.

                                      documents, States may choose to
                                      characterize the concern as a 305(b)
                                      "assessment" issue. This is a rapidly
                                      evolving field, with  many States
                                      attempting to add public health
                                      features to their water quality stan-
                                      dards or expanded standards' provi-
                                      sions for wildlife protection.
                                          Because many of the toxicants
                                      in question are persistent substances
                                      (e.g., chlordane or PCBs), it is often
                                      likely that there are no active pollut-
                                      ant sources; rather the problems are
                                      related to in-place contaminants.
                                      This situation is compounded by the
                                      fact that many of the organic or
                                      heavy metal toxicants are multi-
                                      media problems, with any ongoing
                                      pollutant loading coming from
                                      atmospheric deposition. The sources
                                      for such "air pollution" inputs are
                                      generally not well known; in some
                                      cases the ultimate sources may even
                                      lie outside the United States,  reflect-
                                      ing pollution processes on a hemi-
                                      spheric or global scale. Faced with
                                      these uncertainties, most States are
                                      continuing to gather monitoring
data and are adopting risk manage-
ment strategies.
    In 1994, 39 States and Territo-
ries reported that they found ele-
vated concentrations of toxic con-
taminants in fish,  sediment, or water
column samples representing over
2 million lake acres. These States
surveyed more than 7.5 million lake
acres for toxic contaminants, many
of which had known or suspected
toxicity problems. This information is
difficult to interpret because States
do concentrate their monitoring
efforts on lakes with problems, and
each State uses its own criteria for
defining  "elevated" concentrations
of contaminants.


Trends  in  Significant
Public Lakes	

    A final provision in the 1987
CWA reauthorization encourages
States to make use of available
information  to identify trends in
water quality for  public lakes. With
the possible exception of bog-like
dystrophic lakes,  lakes do naturally
display shifts in trophic status over
time, as well as pollution-induced
trends. Trend analysis can therefore
be extremely valuable in document-
ing the eutrophication rate. Where
possible, trend assessments should
look not only at shifts in trophic
status but at all water quality issues,
including trends involving toxic con-
taminants.
     The  majority  of States do
attempt  some sort of trend determi-
nation. Frequently, determinations
are made based on best professional
judgment (BPJ) rather than more
quantitative tests. Virtually every
State that presents such BPJ  trends

                                                                          Chapter Sixteen Protecting Lakes   423
assessments notes that confidence
limits or other measures of reliability
or precision are not available.
    While the desirability of trend
assessments is widely recognized,
States still face challenges in  gather-
ing adequate information to  statisti-
cally document trend signals.
Although States continue to explore
ways to detect empirically significant
trends, virtually every State
expressed the need to acquire addi-
tional data, a common estimate
being that at least  10 years of
observations would be needed to
apply more rigorous statistical meth-
ods. Another common theme is that
the patterns displayed in many lakes
do not seem to be linear. Most
available statistical tests are geared
to spotting simple, linear trends.
Where the underlying  physical
patterns are nonlinear or cyclical,
more complex analyses are needed.
    Some States do apply quantita-
tive analysis techniques for lake
assessments. Illinois used linear
regressions combined with examina-
tion  of scatter plots of the raw data
and  residuals. From 213 lakes, over
half (56%) of the lakes had compli-
cated fluctuating patterns suggest-
ing cyclical or nonlinear patterns,
perhaps related to weather variabil-
ity. Illinois, therefore, felt that
additional data and further analysis
would be worthwhile.  Wisconsin
and  Minnesota used the Seasonal
Kendall tau test to  look at trends in
water clarity. This is a nonparamet-
ric test considered by many to be
generally preferable to parametric
tests for use with water quality data.
Wisconsin looked at 40 lakes, with
the test suggesting increasing trends
(clearer water) for 16 lakes and
decreasing trends for 6 lakes.
Minnesota reported trends in Secchi
transparency for the 16 lakes with
8 or more years of data. At a 10%
detection level, 13 lakes were con-
sidered to have a significant decline
in transparency and 44 lakes were
considered to have a significant
increase in transparency.
    In 1994, 24 States reported that
of the 1,828 lakes assessed for
trends, 14% were improving, 68%
were stable,  and 18% were degrad-
ing. This information may be some-
what biased, as States often  assess
trends in lakes that are part of a
management study or because of
their easy accessibility. It is likely
that more remote lakes are  under-
represented  in these assessments.

Pollution  Control
and Restoration
Techniques

    Managing lake quality often
requires a combination of in-lake
restoration measures and  pollution
controls,  including watershed
management measures:
    Restoration measures are
implemented to reduce existing
pollution problems. Examples of
in-lake restoration measures include
harvesting aquatic weeds, dredging
sediment, and adding chemicals to
precipitate nutrients out of the
water column. Restoration measures
may not  address the source of the
pollution.
    Pollution controls deal with the
sources of pollutants degrading lake
water quality or threatening to
impair lake water quality.  Control
measures include planning activities,
regulatory actions, and implementa-
tion of best management practices

                                            are examples of planning measures.
                                            Watershed management plans
                                            simultaneously address multiple
                                            sources of pollutants, such as runoff
                                            from urbanized areas, agricultural
                                            activities, and failing septic systems
                                            along the lake shore. Regulatory
                                            measures include point source dis-
                                            charge prohibitions and phosphate
                                            detergent bans.
                                                States are asked to provide
                                            materials on their lake restoration
                                            techniques. For example, States may
                                            provide specific restoration tech-
                                            niques from which-they will draw to

                                            encouraged to document specific
                                                  techniques recommended for indi-
                                                  vidual publicly owned lakes.
                                                      During the 1980s, most States
                                                  implemented chemical and

                                                  that they still implement in-lake

Clean Lakes
Demonstrations

    The 1987 amendments to
Clean Water Act Section 314 estab-
lished the Demonstration Program
for lakes. The Act requires that the
EPA Administrator give priority
consideration to the following 10
lakes for inclusion in the Demonstra-
tion Program: Lake Worth, Texas;
Lake Houston, Texas; Beaver Lake,
Arkansas; Greenwood Lake, New
Jersey; Deal Lake,  New Jersey;
Alcyon Lake, New Jersey; Gorton's
Pond, Rhode Island; Lake Washing-
ton, Rhode Island; Lake Bomoseen,
Vermont; and Sauk Lake, Minne-
sota.
    These 10 lakes have water qual-
ity problems common to many
lakes throughout the United States.
Most of the water quality problems
fall  into two categories: (1) exces-
sive siltation and sediment influx
and (2) high levels of nutrient
loading.
    These water quality problems
have many sources, but most can
be linked to the development of the
lakes' watersheds. Urbanization can
increase runoff from lawns, high-
ways, stormwater outfalls, and other
surfaces. Shoreline development can
result in increased nutrient loading
from inadequate septic systems and
the use of fertilizers on lawns. Rural
development can lead to water
quality problems as well. Farms and
animal production facilities on or
near lakes use and generate large
quantities of nitrogen and phospho-
rus from animal feed, fertilizers,
pesticides, and animal waste. Runoff
from these facilities or fields can
significantly increase the nutrient
load to a lake. Soil erosion that
occurs during construction or from
poorly maintained commercial,
residential, or agricultural lands can
cause a  significant influx of silt and
sediment to a lake.


Demonstration Lakes

    Lake Worth. Lake Worth is the
primary source of drinking water for
the City of Fort Worth, Texas. It is
also a major recreational resource
and is surrounded by almost 4,000
acres of public parks. In recent
years, however, uses of the lake
have been impaired by siltation and
the unchecked growth of aquatic
plants in the shallow areas of the
lake.- Studies conducted over the
past 30 years have given project
principals a clear understanding of
the history and present condition of
the lake and its watershed as well as
a coherent restoration  plan. This
project enjoys very active public
participation, cooperation with the
U.S. Arrny Corps  of Engineers, and
coordination through an inter-
agency planning  committee com-
posed of Federal, State, and local
entities. With the workplan
approved and engineering designs
prepared, the restoration project is
well under way and active. The
project involves installation of an

                                      for the City of Houston, Texas.
                                      Originally, the lake  had a storage
                                      capacity of more than 160,000
                                      acre-feet, but over the years the
                                      capacity of the lake has decreased
                                      by more than 18%. Studies indicate
                                      that the diminished capacity results
                                      from constant sedimentation and
                                      that uses of the lake are impaired
                                      by the excessive growth of aquatic
                                      plants. The current water quality
                                      problems are caused by runoff,
                                      primarily from urbanized areas
                                      around the lake, and  point source

                                          Beaver Lake. Located near
                                      Fayetteville, Arkansas, Beaver Lake is
                                      a 28,190-acre reservoir that serves
                                      as a drinking water supply and rec-
                                      reational facility for the surrounding
                                      population of more than 200,000
                                      people.  Although the lake has
                                      escaped any significant impairment
                                      to date, the State of Arkansas is
                                      concerned that rapid commercial,
                                      agricultural, and residential develop-
                                      ment threatens the water quality of
                                      the lake. Over the years, the Beaver
                                      Lake watershed has been studied
extensively through the cooperative
efforts of several Federal agencies.
All recognize that runoff from the
growing number of chicken and
swine farms  in the watershed could
eventually affect the quality of the
drinking water supply. Studies indi-
cate that water clarity in the upper
reservoir has been  decreasing as a
result of siltation and algal blooms.
The source of the silt and nutrients
is believed to be the increased num-
ber of confined animal production
facilities and the spreading of the
waste from the facilities on nearby
pastures. EPA and the State of
Arkansas are encouraging farmers to
use best management practices
voluntarily to reduce the potential
for nutrient loading to the lake. The
Army Corps of  Engineers undertook
an extensive effort to characterize
the water quality of the lake and to
determine the impacts of the sur-
rounding watershed.  Monitoring
data indicate that the trophic status
of the lake has  not changed signifi-
cantly since  1970. Although point
sources of pollution to the lake have
decreased, nonpoint sources have
increased, resulting in no net
change in nutrient input. No spe-
cific restoration measures have been
recommended.

    Greenwood Lake. Historic
Greenwood Lake is unique among
the Demonstration Program lakes
because it is located in two States,
New Jersey and New York. The lake,
divided almost in half by the New
York/New Jersey State line, is part of
the headwaters for the Wanaque
Reservoir, which is a major water
source for northern New jersey and
a popular recreational area.
Although Greenwood Lake is still a

thriving water resource, it shows
signs of water quality degradation:
adverse changes in fishery popula-
tions, excessive growth of aquatic:
plants, and unpleasant odors and
taste. This degradation is caused by
increased nutrient and sediment
loadings, which are the result of
development in the watershed,
stormwater runoff, septic discharges,
and point source discharges into
tributaries of the lake. Sources of
lake pollution have been identified
and a 10-part restoration plan was
developed in  the 1980s. Some por-
tions of the plan—specifically lake
drawdown and aquatic plant har-
vesting—were implemented as early
as 1985. In addition,  sewage treat-
ment facilities have been  upgraded,
stormwater control measures have
been implemented for new develop-
ments, and runoff conveyances  have
been maintained. Ongoing efforts
include lake level drawdown, weed
harvesting, development of a
stormwater management plan
prioritizing sites, construction of
stormwater detention basins, and a
public education program. Prelimi-
nary results indicate that the recur-
rence of excessive aquatic plants has
decreased. In  addition to the efforts
of the States and EPA, the COE  has
developed a dredging plan for the
lake.

    Deal Lake. Deal Lake is the
largest freshwater body in
Monmouth County, New Jersey. By
1950, sedimentation, algal blooms,
and bacteria concentrations had
become so excessive  that recre-
ational uses were impeded or
prohibited. State and local interest
in  restoring the lake culminated in
1983 in a State-sponsored
comprehensive diagnostic/feasibility
study. This study determined the
primary source of sediment to be an
old landfill located upstream of the
lake. The source of nutrients and
bacteria appears to be excrement
from the abundant waterfowl that
inhabit the lake. This study also
defined a remediation plan that
included in-lake work such as
dredging and drawdown, as well as
watershed management elements
such as stabilization of the upstream
landfill, stormwater management,
erosion control, and the protection
of sensitive habitats. The  remedia-
tion plan was initiated in  1988 with
$1  million of State funds. After the
landfill was stabilized, a heavily
sedimented portion of the lake was
restored by dredging, construction
of a sediment trap, wetland
enhancement, and reclamation of

                                         Alcyon Lake. Alcyon Lake is a
                                     small manmade lake located in
                                     Pitman, New Jersey. The lake has
                                     been a center of community activity
                                     since the  1890s when Alcyon Park
                                     was built  on the lakeshore. In 1951,
                                     Alcyon Park was sold  and essentially
                                     abandoned. By 1980, three sources
                                     of pollution had been identified:
                                     (1) the LiPari Landfill, an abandoned
                                     chemical waste dump; (2) urban
                                     stormwater runoff; and (3) agricul-
                                     tural runoff. This pollution had been
                                     ongoing for over 20 years. In 1980,
                                     it was determined that the major
                                     problem at the lake was the dis-
                                     charge of approximately 150,000
                                     gallons of chemical waste from the
                                     LiPari Landfill. The LiPari Landfill was
                                     designated as a Superfund project
                                     and the landfill is now contained.
                                     The Superfund Program is now
                                     dredging  contaminated sediments
                                     from the  lake and area streams and
                                     wetlands. Under the Clean Water
                                     Act, the Lake Demonstration Pro-
                                     grams focused  on the urban and
                                     agricultural sources of pollution to
                                     the  lake. This effort is in progress
                                     and includes (1) examination of the
                                     stormwater drainage system to
                                     identify problem areas, (2) a volun-

                                     with the Soil Conservation Service
(recently renamed the Natural
Resources Conservation Service) to
implement watershed erosion
control measures.

    Gorton's Pond. Located near
Warwick, Gorton's Pond is in a
heavily urbanized area of Rhode
Island. Consequently, it has many of
the pollution problems associated
with residential and commercial
development. These include surface
runoff that contains oil, grease,
bacteria, fertilizers (nutrients), and
sediment. Resulting problems are
algal blooms, overgrowth of aquatic
vegetation, and a decline in the
fishery. Recommendations from an
initial study stressed that the resto-
ration plan must deal with the
causes of the water pollution—land
use practices in the watershed—
as well as in-lake work. Land use
management recommendations
included erosion and sediment
control, particularly during construc-
tion and at stormwater outfalls;
stormwater treatment and/or diver-
sion; and elimination of  point and
nonpoint source discharges such  as
onsite sewage disposal systems.
In-lake methods  proposed included
limited dredging, nutrient inactiva-
tion, and aquatic plant harvesting.
The design phase of a stormwater
infiltration basin  has been com-
pleted but the basin  has not been
constructed.

    Lake Washington. Located in
upper northwestern Rhode Island,
Lake Washington is a shallow basin
constructed more than 80 years
ago. In  recent years,  excessive
growth  of aquatic vegetation,
algal blooms, and increased sedi-
mentation have occurred. The

                                                                           Chapter Sixteen Protecting Lakes  429
decomposition of the aquatic plants
and algae has decreased the dis-
solved oxygen content in the water,
threatening the survival of the fish
population. Part of the water quality
problems stem from the fact that
the lake has a naturally low inflow
of water, primarily ground water,
and consequently has poor flushing.
In addition, many lakeshore resi-
dents are on septic systems that
have exceeded their useful life. A
further source of pollution is runoff
from a highway that abuts the
lakeshore. Failing septic systems
have been identified as the primaiy
source of nutrients to the lake, and
a centralized wastewater treatment
system has been recommended.
In-lake work such as drawdown,
harvesting, and algicides may also
be needed, as well as watershed
management activities such as revi-
sion of local land ordinances, rip rap
and vegetative swells, land acquisi-
tion, and better maintenance of
stormwater drainage systems.

    Lake Bomoseen. Lake
Bomoseen is the largest lake located
entirely within Vermont. It covers
2,364 acres and has an average
depth of 27 feet. As a result, the
lake is a major recreational resource
and contributes to the economy of
the region. Since 1982, the aquatic
plant Eurasian water milfoil has
spread rapidly in some areas of the
lake. It is estimated that the plant.
occupies more than 600 acres of
the lake out to a depth of 20 feet.
The Eurasian milfoil coverage is  very
dense and has severely restricted
use of the lake.  In the 1980s
mechanical harvesters were used to
remove the plants from the lake's
surface, but this method proved to
be ineffective and uneconomical in
controlling the plant growth. In
1989, staff of the Vermont Depart-
ment of Environmental Conservation
(DEC) discovered a dramatic decline
in milfoil growth in Brownington
Pond in northeastern Vermont. The
decline appeared to be associated
with the presence of a particular
native herbivorous (plant-eating)
aquatic weevil that feeds on Eur-
asian milfoil. In 1990, DEC began a
5-year research project on the use
of the native insect as a  biological
control for milfoil in Lake Bomoseen
as well as the other 2.5 lakes in Ver-
mont that have a milfoil problem.
The  goal of the project is to deter-
mine the extent to which the
aquatic weevil might contribute to
milfoil reduction and the suitability
of Lake Bomoseen and other lakes
for weevil introduction. The project
has involved determining the distri-
bution and abundance of the native
weevil in Vermont lakes, field collec-
tion  of adult weevils for  rearing
stock, weevil rearing  in a laboratory
greenhouse, introduction of weevils
into  specific lake sites, and monitor-
ing to determine survival of the
weevils and feeding damage to
milfoil plants. Results from the
quantitative sampling effort done at
the three weevil introduction sites
on Lake Bomoseen are not yet avail-
able. However, visual observations
indicate that the weevils have
damaged the milfoil at all three sites
and  that some milfoil populations in
shallow water are starting to col-
lapse. Norton Brook Reservoir also
received weevil introductions; how-
ever, introductions at this site were
discontinued due to a lack of posi-
tive results. Unlike the observations
at Bomoseen, little evidence of

                                      surviving weevils and weevil feeding
                                      damage was seen at this site. There-
                                      fore, at this point it is difficult to
                                      predict how successful the weevils
                                      will be at reducing Eurasian milfoil.

                                          Sauk Lake. Sauk Lake covers
                                      2,111 acres in central Minnesota
                                      and has a predominantly agricul-
                                      tural watershed encompassing
                                      5 counties, 49 townships, and
                                      28 cities. The overgrowth of aquatic
                                      plants and algae has severely
                                      curtailed or entirely discontinued
                                      the recreational uses of the lake.
                                      The sources of nutrient and sedi-
                                      ment pollution are agricultural and
urban runoff within the watershed
and upstream of Sauk Lake. The
State has -begun to control these
sources and prevent pollution in the
upstream Lake Osakis watershed
area. Measures include agricultural
best management practices such as
no-till farming and feedlot runoff
diversion, streambank and shoreline
erosion control, urban stormwater
diversion, and a community educa-
tion program. Meanwhile, the Army
Corps of Engineers has been imple-
menting a harvesting effort to re-
duce the aquatic plants in Sauk
Lake.

Wetlands  Protection  Programs
   A variety of public and private
programs protect wetlands. The
Conservation Foundation organized
the bipartisan National Wetlands
Policy Forum in 1987 to coordinate
these disparate efforts and develop
a national, coordinated vision for
wetlands protection. The Forum
issued a report in November 1988
containing over 100 recommended
actions  for all levels of government
and the private sector. It established
an interim goal to achieve no over-
all net loss of the Nation's wetlands
base and a long-term goal to
increase the quantity and quality of
the Nation's wetlands resource base.
Shortly after coming into office, the
Clinton Administration convened an
interagency working group to
address concerns with Federal wet-
lands policy. After hearing from
States,  developers, farmers, environ-
mental  interests, members of Con-
gress, and scientists, the working
group developed a comprehensive
40-point plan for wetlands protec-
tion to  make wetlands programs
more fair, flexible, and effective.
This plan was issued on August 24,
1993.

Section 404

   Section 404 of the Clean Water
Act continues to provide the pri-
mary Federal vehicle for regulating
certain  activities in wetlands. Section
404 establishes a permit program
for discharges of dredged or fill
material into waters of the United
States,  including wetlands.
   The U.S. Army Corps of Engi-
neers and EPA jointly implement the
Section 404 program. The COE is
responsible for reviewing permit
applications and making permit
decisions. EPA establishes the envi-
ronmental criteria for making permit
decisions and has the authority to
review and veto Section 404 per-
mits proposed for issuance by the
COE. EPA is also responsible for
determining geographic jurisdiction
of the Section 404 permit program,
interpreting statutory exemptions,
and overseeing Section 404 permit
programs assumed by individual
States. To date, only two States
(Michigan and New Jersey) have
assumed the Section 404 permit
program from the COE. The COE
and EPA share responsibility for
enforcing Section  404 requirements.
   The COE issues individual Sec-
tion 404 permits for specific projects
or general permits (Table 17-1).
Applications for individual permits
go through a review process that
includes opportunities for EPA, other
Federal agencies (such as the U.S.
Fish and Wildlife Service and the
National Marine Fisheries Service),
State agencies, and the public to
comment. However, the vast major-
ity of activities proposed in wetlands
are covered by Section 404 general
permits. For example, in FY94, over
48,000 people applied to the COE
for a Section 404  permit. Eighty-two
percent of these applications were
covered by general permits and
were processed in an average of 16
days. It is estimated that another
50,000 activities are  covered by
The Administration's
Wetlands Plan emphasizes
improving Federal wetlands
policy by

  • Streamlining wetlands
    permitting programs
  • Increasing cooperation
    with private landowners
    to protect and restore
    wetlands
  • Basing wetlands protec-
    tion on good science and
    sound judgment
  • Increasing participation
    by States, Tribes, local
    governments,  and the
    public in wetlands

434   Chapter Seventeen Wetland Protection Programs
                                      general permits that do not require
                                      notification of the COE at all.
                                          General permits allow the COE
                                      to permit certain activities without
                                      performing a separate individual
                                      permit review. Some general
                                      permits require notification of the
                                      COE before an activity begins. There
                                      are three types of general permits:

                                      •  Nationwide permits (NWPs)
                                      authorize specific activities across
                                      the entire Nation. NWPs cover
                                      categories of activities that the COE
                                      determines will have only minimal

                                      on the environment. Currently, 36
                                      NWPs authorize activities including
                                      construction of minor road crossings
                                      and farm buildings, bank stabiliza-

                                      authorize activities in a specific
waterbody, a county, a State, a COE
district, or multiple States within a
COE district.

•  Programmatic general permits
are issued to an entity that the COE
determines may regulate activities
within its jurisdictional wetlands.
Under a programmatic general per-
mit, the COE defers its permit deci-
sion to the regulating entity but
reserves its authority to require an
individual permit. Under State pro-
grammatic general permits (SPGPs),
the COE defers permit decisions to
a State program for specific activi-
ties throughout the State or in a
significant portion of the State.

    Currently, the COE and  EPA are
promoting the development of
SPGPs to increase State involvement
in wetlands protection and minimize
duplicative State and Federal review
of activities proposed in wetlands.
Each SPGP is a unique arrangement
developed by a State and  the COE
to take advantage of the strengths
of the individual State wetlands
program. SPGPs may cover all

regulated activities in a State or a
select set of activities in a portion of
the State. Several  States have
adopted comprehensive SPGPs that
replace  many or all COE-issued na-
tionwide general permits (see high-
light on page 442).
    SPGPs simplify the regulatory
process  and increase State control
over their wetlands resources. Care-
fully developed SPGPs can improve
wetlands protection  while reducing
regulatory demands on landowners.

Wetlands Water
Quality Standards

    Water quality standards for
wetlands ensure that the provisions
of CWA Section 303 that apply to
other surface waters are also applied
to wetlands. In July 1990, EPA
issued guidance to States for the
development of wetlands water
quality standards.  Figure 17-1 indi-
cates the State's progress in devel-
oping these standards (see Appen-
dix D, Table D-5, for individual
State data).
    Water quality  standards have
three major components:  desig-
nated uses, criteria to protect those
uses, and an antidegradation policy.
States designate uses that must, at a
minimum, meet the goals of the
CWA by providing for the
protection and propagation  of fish,
shellfish, and wildlife and for recre-
ation in  and on the water. States
may choose to designate additional
uses for  their wetlands,  such as
flood water attenuation or ground
water recharge where appropriate.
Once uses are designated, States are
required to adopt criteria sufficient
to protect their designated uses.
Criteria are general narrative state-
ments or specific numerical values
such as concentrations of contami-
nants and water quality characteris-
tics. Narrative criteria can be par-
ticularly appropriate for wetlands
when quantitative data do not exist.
An example of a narrative criterion
is "natural hydrological conditions
necessary to support the biological
and physical characteristics naturally
present in wetlands shall be
protected."
    Standards provide the founda-
tion for a broad range of water
quality management activities  under
the CWA including, but not limited
to, monitoring for the Section
305(b) report, permitting under
Sections 402 and 404, water quality
certification under Section 401, and
the control of nonpoint source
pollution under Section 319.

                                        In 1989,  EPA issued guidance to
                                     States and American Indian Tribes
                                     on how to use 401  certification
                                     authority to protect wetlands.
                                     Section 401 certification can be a
                                     powerful  tool for protecting wet-
                                     lands from unacceptable degrada-
                                     tion or destruction, especially when
                                     implemented in conjunction with

                                     dards. Section 401 grants States and
                                     Tribes the authority to deny certifi-
                                     cation or require conditions for
                                     certification if the State or Tribe
                                     determines that an applicant has
                                     failed to demonstrate that a project
                                     will comply with State or Tribal
                                     water quality standards. If a State or
                                     eligible Tribe denies Section 401
                                     certification, the Federal permitting
                                     or licensing agency cannot  issue the
                                     permit or license.
                                        Most States now use their
                                     Section 401 certification programs
to review activities requiring both
Section 404 individual permits and
selected general permits. Until
recently, many States waived their
right to review and certify individual
and general Section 404 permits
because these States had not
defined water quality standards for
wetlands or codified regulations for
implementing their 401 certification
program into State law. Now, most
States report that they use the
Section 401 certification process to
review Section  404 projects and to
require mitigation if there is no
alternative to degradation of
wetlands.
    Ideally, 401 certification should
be used to augment State programs
because it applies only to projects
requiring Federal permits or licenses.
Activities that do not require
permits, such as some ground water
withdrawals, are  not covered.

State Wetlands
Conservation Plans

    State Wetlands Conservation
Plans (SWCPs)  are strategies that
integrate regulatory and cooperative
approaches to  achieve State wet-
lands management goals, such as
no overall net loss of wetlands.
SWCPs are not meant to create a
new level of bureaucracy. Instead,
SWCPs improve government and
private-sector effectiveness and
efficiency by identifying gaps in
wetlands protection programs and
identifying opportunities to improve
wetlands programs.
    A large number of land- and
water-based activities impact
wetlands. These activities are not
addressed by a single Federal, State,

or local agency program. Although
many public and private programs
and activities protect wetlands,
these programs are often limited in
scope and are not well coordinated.
Also, these programs often do not
address all of the problems affecting
wetlands.
    States, Territories, and Tribes are
well positioned between Federal
and local government to take the
lead in integrating and expanding
wetlands protection and manage-
ment programs. They are experi-
enced in  managing federally man-
dated environmental programs
under the Clean Water Act and the
Coastal Zone Management Act.
They are  uniquely equipped to help
resolve local and regional conflicts
and identify the local economic and
geographic factors that may influ-
ence wetlands protection.

•  Texas'  SWCP will focus on
nonregulatory and voluntary
approaches to wetlands protection
to complement its regulatory
program. The plan will encourage
development of economic incentives
for private landowners to protect
wetlands  and educational outreach
for State and local officials.

•  Tennessee's plan focuses on a
strategy to collect wetlands  informa-
tion for outreach and education to
private owners of wetlands as well
as to regional and local decision-
makers. Current implementation
efforts include identification  of criti-
cal functions of major wetlands
types, priority sites for acquisition
and/or restoration, as well as main-
tenance and  restoration of natural
floodplain hydrology through digiti-
zation and use of remote sensing.
•  Maine's SWCP will focus on ways
to establish better coordination
between State and Federal regula-
tory programs as well as new
nonregulatory mechanisms to foster
voluntary stewardship. In addition,
the State expects to use an ecosys-
tem framework to guide the  priori-
tization of wetlands for comprehen-
sive protection and to review and
improve compensator)' mitigation
policies.

Wetlands Monitoring/
Biocriteria  Programs

    Historically, wetlands protection
efforts have concentrated on  regu-
lating the widespread destruction of
wetlands due to the discharge of
dredged and fill  material and on
conservation of wetlands to maxi-
mize tangible benefits such as hunt-
ing and fishing. States have only
recently begun to take steps toward
control of other disturbances that
can result in the degradation of
wetlands. Such disturbances include
hydrologic alteration, vegetation
clearing, introduction of alien spe-
cies, habitat fragmentation, chemi-
cal  pollutants, sedimentation, and
changes in pH, dissolved oxygen,
and temperature. The use of  water
quality standards is an important
tool for States to  use to address
these causes of wetlands degrada-
tion.
    Assessment of the biological
integrity of a wetland is crucial to
characterizing water quality because
aquatic life tends to reflect the
ecological health  of a waterbody
(including physical ancl chemical
conditions) and will reflect a range
of diverse degrading impacts  on a

                                     is limited and  varied, several  States
have begun systematic long-term
regional monitoring and monitoring
of reference sites necessary to sup-
port a wetlands biocriteria program.
Currently, Kentucky, Minnesota,
Montana, and New Mexico are
developing such programs. Other
States have initated projects, often
limited to a specific region, wet-
lands type, or monitoring  method,
that will help them gain experience
and acquire data needed for launch-
ing  a statewide wetlands biomoni-
toring program.

Swampbuster

    The Swampbuster provisions of
the  1985 Food Security Act and the
1990 Food, Agriculture, Conserva-
tion and Trade Act ("Farm Bills")
deny crop subsidy payments and all
other agricultural benefits  to farm
operators who convert wetlands to
cropland after December 23, 1985,
or who  modify wetlands to make
cropping possible after November
28,  1990. The U.S. Department of
Agriculture's Natural Resources Con-
servation Service (formerly the Soil
Conservation Service) is responsible
for determining compliance with
Swampbuster provisions and for
determining whether agricultural
lands fall under the jurisdiction of
Federal wetlands laws, including
both the Swampbuster provisions
and Clean Water Act Section 404.

State Programs  to
Protect Wetlands

    States protect their wetlands
with a variety of approaches, includ-
ing  use  of CWA authorities (such as
Sections 401 arid 303), permitting

programs, coastal management
programs, wetlands acquisition
programs, natural heritage
programs, and integration with
other programs. For this report,
States described particularly innova-
tive or effective approaches they use
to protect wetlands.

State-Reported
Information

    The following trends emerged
from individual State reporting:

•  Most States have defined wet-
lands as waters of the State, which
offers general  protection through
antidegradation clauses and desig-
nated uses that apply to all waters
of a State. However, most States
have not developed specific wet-
lands water  quality standards and
designated uses that protect wet-
lands' unique functions, such as
flood attenuation and filtration.

•  Without specific wetlands uses
and standards, the Section 401
certification  process relies heavily on
antidegradation clauses to prevent
significant degradation of wetlands.

•  In many cases, the States use  the
Section 401  certification process  to
add conditions to Section  404
permits that minimize the size of
wetlands destroyed  or degraded  by
proposed activities to  the extent
practicable.

    States often add conditions that
require compensatory mitigation for
destroyed wetlands, but the States
do not have the resources to
perform enforcement  inspections or
followup monitoring to ensure that
the constructed wetlands are func-
tioning properly.

•  More States are monitoring
selected, largely unimpacted
wetlands to establish baseline condi-
tions in healthy wetlands. The States
will use this information to monitor
the relative performance of con-
structed wetlands and to help estab-
lish biocriteria and water quality
standards for wetlands.

    Some highlights from individual
State reports are as follows:

•  The District of Columbia adopted
narrative criteria for wetlands in
their 1994 water quality standards.
Wetlands are now classified for des-
ignated use categories of Class C
(the protection and propagation of
fish, shellfish, and wildlife) and Class
D  (the protection of human health
related to consumption  of fish and
shellfish). Wetlands are now pro-
tected  from significant adverse
hydrologic modifications, excessive
sedimentation, deposition  of toxic
substances in toxic amounts,  nutri-
ent imbalances, and other adverse
impacts from human activities.

•  Massachusetts made significant
progress in establishing wetlands-
specific criteria. The State defined
wetlands as  waters of the State,
designated uses for wetlands,
adopted aesthetic narrative criteria
and very general numeric criteria for
wetlands, and drafted an antidegra-
dation  policy. The State intends to
complete and implement the
antidegradation policy;  draft narra-
tive biological criteria; develop
specific numeric criteria for appro-
priate parameters; develop criteria

                                      drafted regulations for implement-
                                      ing the 401  program during the
                                      1994 reporting cycle.

                                      •  During 1992 and 1993, Minne-

                                      the 1991  Minnesota Wetlands
                                      Conservation Act. These rules
                                      require local governments to regu-
                                      late the draining and filling of
                                      wetlands not classified as "public
                                      waters wetlands." Twenty-five
                                      exemptions  are included in the Wet-
                                      lands Conservation Act and Rules.
                                      Minnesota also began comprehen-
                                      sive wetlands conservation planning
                                      in 1993. An interagency task force
                                      staffed through the Minnesota
                                      Department of Natural Resources
                                      will develop statewide wetlands
                                      goals and guidance for coordinating
                                      local, State,  and Federal wetlands
                                      programs.

                                      Minnesota added specific  definitions
                                      of wetlands  to  their water quality
                                      standards, assigned water use classi-
                                      fications to wetlands, adopted nar-
                                      rative nondegradation standards to
                                      protect wetlands, and implemented
                                      a wetlands mitigation process. The
                                      Minnesota Pollution Control Agency
                                      began surveying reference wetlands
                                      sites to develop biological and
                                      chemical criteria for the wetlands
                                      use classifications and to assess the
                                      biological and chemical health of
                                      wetlands throughout the State.
•  Nebraska adopted specific wet-
lands water quality standards in
November 1993. The standards
classify wetlands into two catego-
ries: isolated wetlands and surface
water overflow wetlands that are
adjacent to lakes or streams. The
beneficial uses of aquatic life, wild-
life habitat, agricultural use, and
aesthetics are assigned to all wet-
lands. In addition, surface water
overflow wetlands are protected for
the assigned beneficial uses of the
adjacent lake or stream. The State
assigned narrative water quality
criteria to protect the beneficial uses
and numeric criteria to protect uses
from toxic pollutants.

•  Ohio is in the process of drafting
standards to protect the functional
values of wetlands, including desig-
nated uses, narrative criteria, and an
antidegradation  policy specifically
for wetlands. The State is also  devel-
oping performance goals for wet-
lands mitigation projects and
designing a monitoring program to
support both wetlands water quality
standards and the mitigation perfor-
mance goals.

•  Wisconsin Administrative Code
NR 103 established wetlands water
quality standards in 1991 that
include narrative criteria to protect
specific wetlands values and
functions, such as storm and flood
water storage, water cycle functions,
filtration of pollutants,  shoreline
protection, wildlife habitat, and
recreational and scientific values.

The standards have greatly
enhanced the effectiveness of
Wisconsin's Section 401 Water
Quality Certification Program by
providing legal criteria for denying
or adding conditions to proposed
activities that will have a significant
adverse impact on wetlands  values
and functions. The standards have
controlled impacts to wetlands with-
out halting all activities in  wet-
lands—the State granted 401 Certi-
fication to more than half  of the
wetlands permit applications re-
viewed between 1991 and 1994.
Summary
    There are a variety of public
and private programs to protect
wetlands. A forum was held in 1987
to coordinate these and provide
national direction in the area of
wetlands. Section 404 of the Clean
Water Act is the major Federal pro-
gram for regulating activities in
wetlands. Other important tools to
protect wetlands include voluntary
stewardship, wetlands water quality
standards, State  water quality certifi-
cation, State wetlands conservation
plans, emergency wetlands reserve
and conservation reserve programs,
and Swampbuster provisions of the
Farm bills, as well as incorporating
wetlands considerations into other
programs such as the Section 319
Nonpoint Source Program.
    States reported that they are
making progress in developing their
programs to protect wetlands,
especially in the areas of application
of 401 certification, development of
water quality standards for wet-
lands, State programmatic general
permits, and formation of more
efficient joint application procedures
for permits. Despite these efforts,
States reported that they continue
to lose wetlands and the pressure to
develop in  wetlands remains high.
In addition, there is little known
about the quality  of the remaining
wetlands. States put forward a vari-
ety of recommendations on how to
improve protection of wetlands,
including consideration of wetlands
on a landscape or ecosystem basis,
development of scientific tools for
States to assess and monitor eco-
logical and  water  quality functions
of wetlands, greater sensitivity for
arid climates, and regulation of
additional activities that impact
wetlands.

                                     The  New  Hampshire  State
                                     Programmatic General  Permit
   On June 1, 1992, the U.S. Army
Corps of Engineers (COE) issued a
New Hampshire State Programmatic
General Permit (NHSPGP) and simul-
taneously revoked most nationwide
permits for use in the State of New
Hampshire. These actions stream-
lined the wetlands permitting pro-
cess by consolidating the Federal
Section 404 permit review process
with  New Hampshire's  own compre-
hensive permitting process for activi-
ties proposed in wetlands. The
actions also eliminated  much of the
confusion surrounding  nationwide
general permits.
   Under the NHSPGP, the New
Hampshire Department of Environ-
mental Services (DES) Wetlands
Bureau and the New Hampshire
Wetlands Board perform the initial
review of all projects proposed in
the State's  wetlands. The Wetlands
Board makes the initial permit deci-
sions, based on information and
recommendations provided by DES.
The New Hampshire Wetlands Laws
of 1967 and 1969 require permits
from the Wetlands  Board for all
projects proposed in the State's
wetlands, regardless of project size.
There are no exemptions for agricul-
tural or silvicultural  activities or
activities proposed by Federal, State,
or local agencies. The Wetlands
Board consists of representatives
from eight State agencies and four
members of the public.
    The Wetlands Board issues three
types of permits for activities pro-
posed in wetlands:

• Minimum impact permits for
projects that impact less than  3,000
square feet

• Minorjmpact  permits for projects
that impact less than 20,000 square
feet (about half an  acre)

• Major impact permits for projects
that impact more than 20,000
square feet.

    The NHSPGP establishes the
following procedures for processing
each of the New Hampshire
permits.
                                                                                    ,, i^teia^i$4i^^wMii^^^

•  All projects that receive a mini-
mum impact permit from the Wet-
lands Board automatically fall under
the NHSPGP, with no COE action
required. The Wetlands Board noti-
fies permit applicants that the per-
mitted project may commence
without COE action.

•  The COE and other Federal
agencies screen projects that receive
a minor impact permit from the
Wetlands Board to determine if the
project meets conditions of the
NHSPGP or requires an individual
Section 404 permit. The COE  noti-
fies the applicant within 30 days  if
an individual Section  404 permit  is
required. Projects with minor impact
permits are approved automatically
if the COE does not intervene in  30
days and the project  meets the
conditions of the NHSPGP.

•  The COE and other Federal agen-
cies screen projects that receive a
major impact permit from the Wet-
lands Board to determine if the
project meets conditions of the
NHSPGP or requires an individual
Section 404 permit. The COE
should notify the applicant within
30 days if an individual Section 404
permit is required,  but lack of notifi-
cation  does not provide automatic
approval for major projects. The
applicant must receive affirmative
notification before they initiate
projects with major impact permits.

    The following categories of
projects and activities  are excluded
from the NHSPGP and automatically
require an individual Federal Section
404 permit:

•  Projects that will fill more than
3 acres of wetlands or other U.S.
waters

•  New boating facilities,  including
marinas,  yacht clubs, boat clubs,
and public docks

•  Projects within the  limits  of a
COE navigation project

•  Discharge of spoils  in the  ocean

                                        •  Projects of national concern
                                        (such as significant fill of wetlands
                                        or projects that could affect archeo-
                                        logical sites).

                                            During the first year of NHSPGP
                                        implementation, New Hampshire
                                        reported a 76% reduction in the
                                        number of Section 404 individual
permits issued and a sevenfold in-
crease in the number of projects
receiving documented Federal com-
pliance with Section 404. The
NHSPGP process appears  to benefit
everyone. The NHSPGP relieves
permit applicants of time-consum-
ing parallel State and Federal per-
mitting procedures, reduces the
COE's average review period for
general permits,  and frees up lim-
ited Federal and  State staff to review
major projects.
    The NHSPGP also eliminates
confusion over nationwide general
permits. Prior to  implementation of
the NHSPGP, permit applicants who
received nationwide permits often
did not realize that they also
needed a State permit.  Conversely,
applicants who received State per-
mits often assumed that they quali-
fied for a nationwide general permit
and failed  to apply for a required
Section 404 individual permit.

                                     Wetlands Plan
                                         Shortly after coming into office,
                                     the Clinton Administration convened
                                     an interagency working group to
                                     address legitimate concerns with
                                     Federal wetlands policy. After hear-
                                     ing from States, developers, farmers,
                                     environmental interests, members of
                                     Congress, and scientists, the work-
                                     ing group  developed a comprehen-
                                     sive 40-point plan to enhance wet-
                                     lands protection while making wet-
                                     lands regulations more fair, flexible,
                                     and effective. The plan was issued
                                     on August 24, 1993.
                                         The Administration Wetlands
                                     Plan emphasizes improving Federal
                                     wetlands policy by streamlining
                                     wetlands permitting programs;
                                     increasing  cooperation with private
                                     landowners to protect and restore
                                     wetlands; basing wetlands protec-

                                     protection. The Administration has
                                     already taken a number of actions
                                     to implement the Wetlands Plan,
                                     including the following steps:
• Proposed a nationwide general
permit and created an administra-
tive process to minimize the regula-
tory burden on small landowners for
small projects on their land

• Clarified, by regulation, that prior
converted croplands are not wet-
lands under both the Swampbuster
and CWA programs

• Gave the U.S. Department of
Agriculture the responsibility for
identifying wetlands on agricultural
lands for both Swampbuster and
CWA programs

• Issued policies that have
increased flexibility in wetlands
permitting and  reduced burdens on
permit applicants

• Allowed for greater flexibility in
permitting requirements in Alaska,
due to the unique circumstances in
that State

• Made it easier for permit appli-
cants to use mitigation "banks"

• Requested increased funding for
the Wetlands Reserve Program to
assist farmers who want to restore

• Increased funding to States,
Tribes, and local governments for
wetlands programs.

    These efforts are only the first
steps that the Administration is tak-
ing to reduce the burden of Federal
wetlands regulations. Activities cur-
rently under development include

• Clarifying exemptions  of man-
made wetlands from Federal juris-
diction

• Establishing clear and firm dead-
lines for COE permit decisions

• Allowing administrative appeals
of permit denials and wetlands juris-
dictional determinations as an alter-
native to expensive and time-
consuming litigation

•  Establishing a wetlands delineator
certification program to expedite
regulatory decisions and improve
the quality and consistency of
wetlands delineations performed by
private consultants
 • Improving wetlands assessment
 techniques so that permit decisions
 better reflect the fact that all
 wetlands do not function in the
 same manner

 • Developing guidance to promote
 the use of Section 404 program-
 matic general permits that reduce
 overlap between State and Federal
 wetlands permitting  procedures and
 provide additional flexibility to State
 and local governments

 • Expanding the Wetlands Reserve
 Program to all 50 States and allow-
 ing more types of land to qualify for
 the program.

    Most of these actions ease the
 Federal wetlands permitting burden
 on small landowners and farmers.
The Administration is committed to
 meeting our Nation's wetlands pro-
tection objectives without imposing
 unnecessary burdens on America's
farmers and individuals who own
property that happens to include
wetlands.

                           How the ADID Process
                           Works

                              The ADID process involves col-
                           lecting and distributing information
                           on the values and functions of wet-
                           lands areas. EPA conducts the pro-
                           cess in cooperation with the U.S.
                           Army Corps of Engineers and in
                           consultation with States or Tribes
                           and local interests. Local communi-
                           ties can use this information to help
                           them better understand the values
                           and functions of wetlands in their
                           areas. It also serves as a preliminary
                           indication of factors likely to be
                           considered during review of a
                           Section 404 permit application.
                              The ADID process is intended to
                           add predictability to the wetlands
                           permitting process as well as better
                           account for the impacts of  losses
                           from multiple projects within a
                           geographic area.
                               Although an ADID study gener-
                           ally classifies wetland areas  as suit-
                           able or unsuitable for the discharge
                           of dredged or fill material, the classi-
                           fication does not constitute either a
                           permit approval or denial and
                           should be used only as a guide by

 Status of ADID Projects

    As of February 1993, 38 ADID
 projects had been completed and
 33 were ongoing. The projects
 range in size from less than 100
 acres to more than  4,000 square
 miles and are located from Alaska to
 Florida, as shown in the map. ADID
 projects can be resource-intensive
 activities, although some have been
 completed in as little as 6 months.
    Regional EPA experience indi-
 cates that the smaller or more local
 the ADID project boundaries, the
 more complete and effective the
 analysis and results.  For example,
ADID projects have  been initiated
 by local entities to facilitate plan-
 ning efforts such as  the one under-
taken in West Eugene,  Oregon. In
this particular study, local ADID
efforts led to an abbreviated Section
404 permit process. Because the
ADID was incorporated into the City
of Eugene's general  comprehensive
plan and because Oregon land-use
policies have the effect of local
 land-use law, the ADID effort
 streamlined the regulatory process.
 These local efforts have proven to
 be one  of the more successful ways
 of generating support for wetlands
 protection. Local cooperation and
 support, are vital to the success of
 ADID projects.
    The number of ADID projects
 has increased over time/and EPA
 expects more States, Tribes, locali-
 ties, and private organizations to
 become involved  in providing funds
 and otherwise supporting ADID or
 other comprehensive planning
 efforts. Because ADID efforts are
 usually based on watershed plan-
 ning,  they are extremely compatible
with geographic and ecosystem
 initiatives such as  EPA's Watershed
 Protection Approach.

                                       Wetlands Mitigation Banking
                                          Mitigation banking has the
                                       potential to play a significant role in
                                       the Section 404 regulatory program
                                       by reducing uncertainty and delays as
                                       well as improving the success of wet-
                                       lands mitigation efforts. Landowners

                                       ated with development activities may
                                       have the option of purchasing credits
                                       from  an approved mitigation bank
                                       rather than restoring or creating wet-
                                       lands on or near the development site.
                                          A wetlands mitigation bank is a
                                       wetlands area that has been
                                       restored, created, enhanced, or (in
                                       exceptional circumstances) pre-
                                       served, which is then set aside to
                                       compensate for future conversions
                                       of wetlands for development activi-
                                       ties. A wetlands bank may be cre-
                                       ated when a government agency, a
                                       corporation, or a nonprofit organiza-
                                       tion undertakes such activities under
                                       a formal agreement with a  regula-
                                       tory agency. The value of a bank is
                                       determined by quantifying the wet-
                                       lands values restored or created in
                                       terms of "credits."
Benefits of Mitigation
Banking

• Banking can provide more cost-
effective mitigation and reduce
uncertainty and delays for qualified
projects, especially when the project
is associated with a comprehensive
planning effort.

• Opportunities for successful miti-
gation are increased since the wet-
lands can be functional in advance
of project impacts.

• Banking can eliminate or reduce
the temporal losses of wetlands
values that typically occur when
mitigation is initiated during or after
the development impacts occur.

• Consolidation of numerous small,
isolated, or fragmented mitigation
projects into a single large parcel
may result in increased ecological
benefits.

• A mitigation bank can bring sci-
entific and planning expertise and
financial resources together, thereby
increasing the likelihood of success
in a way not practical for individual
mitigation efforts.

 Ground  Water
 Protection  Programs
    Fifty-one percent of the Nation's
 population depended upon ground
 water as a source of drinking water
 in 1990 (U.S. Geological Survey
 Circular 1081, 1993).  In addition to
 providing much of our Nation with
 drinking water, ground water is
 used for agricultural, industrial,
 commercial, and mining purposes.
    The importance of our Nation's
 ground water resources is evident.
 Unfortunately, ground water is vul-
 nerable to human contamination,
 and, in the 1994 305(b) reports,
 States identified 66 contaminant
 sources that threaten the integrity of
 ground water resources. Because it
 is expensive and technologically
 complex to remediate ground water
 resources that have been adversely
 impacted by human activities,
 ground water protection has
 become the focus of numerous
 State and Federal programs.
   This chapter presents an over-
 view of ground water protection
 programs and activities that have
 been described  by the States in
 their 1994 305(b) reports and the
 laws and programs instituted by the
 Federal Government to provide a
framework for ground water protec-
tion for the States.
 State Programs


    In their 1994 State 305(b)
 reports, States provided narratives
 detailing legislation, statutes, rules,
 and/or regulations dedicated to
 ground water protection that are in
 place, pending, or under develop-
 ment. The narratives also high-
 lighted major studies undertaken by
 the States in the interest of ground
 water protection, issues  related to
 ground water quality that are cur-
 rently of concern or may be in the
'future, and progress in developing
 and implementing ground water
 protection programs. The purpose
 of these narratives was to provide
 an indication of the comprehensive
 nature of ground water protection
 activities among the States.
    Clearly, States are committed to
 a number of activities to address
 existing ground water contamina-
 tion problems and to prevent future
 impairments of the resource.  These
 activities include enacting legislation
 aimed at the development of com-
 prehensive ground water protection
 programs and promulgating protec-
 tion regulations; adopting and
 implementing ground water protec-
 tion strategies; adopting ground
 water classification and mapping
 programs; and establishing

                                         Forty-six of the 58 responding
                                     States, Territories, and Tribes report
                                     some form of current or pending
                                     legislation geared specifically to
                                     ground water protection. Generally,
                                     legislation focuses on the need for
                                     program development,  increased
                                     data collection, and public
                                     education activities. In many States
                                     and Tribes, legislation also mandates
                                     strict technical controls  such as

discharge permits, underground
storage tank registrations, and
protection standards. Additionally,
some States and Tribes have
enacted legislation establishing  a
policy to restore and maintain
ground water quality and remediate
pollution that has occurred.
    Minnesota passed the Ground
Water Protection Act (GWPA) of
1989 and continues to fund projects
such as ground water monitoring
and data management, increased
control of pesticides and fertilizers,
agricultural chemical cleanups, and
local water plans. The law also
states that ground water quality
should be  maintained so that it is
continually free of human-induced
pollutants.
    The Michigan Legislature
enacted the Environmental
Response Act to identify, prioritize,
and fund the cleanup of environ-
mentally contaminated sites in cases
where responsible parties do not
provide relief. The Michigan Depart-
ment of Natural Resources coordi-
nates the State program with the
Federal Superfund program. The
two  programs are complementary
in their goals and objectives.
    The primary legislation for
Illinois ground water protection, the
Illinois Groundwater Protection Act
(IGPA), was enacted in 1987. The
Act establishes the policy of the
State to "restore, protect and
enhance the ground waters of the
State, as a  natural and public
resource."
    Discovery of extensive contami-
nation in the State's ground water
prompted Arizona to develop strong
and  comprehensive ground water
legislation.  The 1980 Ground Water
Management Act promotes a

strategy of preserving, enhancing,
and protecting current water qual-
ity; remediating, minimizing, and
preventing past, present, and future
discharges to aquifers; and prohibit-
ing discharges of toxic pollutants to
aquifers. This Act defines several
geographic areas in which ground
water supplies are threatened. The
State has designated these areas as
Active Management Areas (AMAs).
Figure 18-2 illustrates one AMA.
Areas in which there is a possible or
known threat to ground water
resources are marked with the
appropriate symbol. Management
plans in these areas address the
threats of both overdrafts and
contaminants.
    In Hawaii, problems with the
quality and reliability of surface
water supplies have led to concern
over the protection of the State's
ground water. The 1987 State
Water Code protects ground water
by authorizing the prohibition,
control, and regulation of activities
in areas vulnerable to ground water
contamination. The  State has
adopted a policy of antidegradation
and uses the authority established
by this legislation  to require proof
that proposed activities will not
degrade ground water before
issuing a permit.
    The Rhode Island legislature

comprehensive ground water pro-
tection policy. Reenacted in 1991, it
emphasized restoring, enhancing,
and maintaining the chemical,
physical, and biological integrity of
Rhode Island's ground water. The
legislature passed this law based on
the belief that ground water is  a
critical renewable resource that
must  be protected  to ensure the
availability of drinking water.

Ground Water
Regulations

    Of the 58 responding States,
Territories, and Tribes, 41 report
that they have established regula-
tions specifically geared toward
protection of ground water quality.
In general, State and Tribal ground
water protection regulations stipu-
late controls for the management of
specific sources of contamination
and standards for ground water
quality protection. These standards
may be used to apply limits on the
allowable discharges from contami-
nant sources and/or to set contami-
nant concentration targets or
threshold levels for ground water
cleanup.
    Nevada has adopted statutory
authority and promulgated associ-
ated regulations to implement  a
mining strategy that is widely con-
sidered to be a model for western
States in terms of both controls
placed upon the mining industry
and the explicit considerations  of
impacts on ground water quality.
Regulations include several
requirements for the purpose of
protecting ground water by
minimizing or preventing discharges
from mining facilities.
    The Florida Department of Envi-
ronmental Regulation (DER) has
established both general and spe-
cific permitting provisions for per-
mitting discharges to ground water.
The regulations require that all dis-
charges to ground water meet cer-
tain water quality conditions, such
as Florida's water quality standards.
    South Carolina's ground water
regulations establish a ground water
classification system to protect pub-
lic health and maintain and enhance
ground water quality. They include
general rules and specific water
quality criteria  to protect classified
and existing water uses. The regula-
tions also set forth narrative stan-
dards for classification and specific
numeric water quality standards for
ground water that is  classified as a
source of drinking water.

Ground Water Protection
Plans

    Fifty-five of the 58 responding
States, Territories, and Tribes have
adopted, or are in the process  of
developing,  ground water  protec-
tion plans. The general content of
these plans includes:  selection of
goals and objectives for ground
water problems identified in the
jurisdiction; development of a
ground water classification system;
program  coordination mechanisms
for local,  State, and Federal ground
water protection activities;  public
education and/or involvement;
development of an interagency
ground water data collection sys-
tem; legislative recommendations
pertaining to the regulation of
contaminating sources; develop-
ment of a ground water monitoring
system; establishment of a WHP
Program; improvement of  existing
ground water protection programs;
and development of statewide

standards for ground water quality.
These plans provide the basis for
their Comprehensive State Ground
Water Protection Programs
(CSGWPPs).
    Texas outlines goals, needs, and
recommendations in six important
areas in its Ground Water Protection
Plan: interagency coordination, haz-
ardous and nonhazardous materials
management, public water supply,
rural water supply, research, and
legislation. Within these areas, each
of the following plan elements  are
discussed: status of existing  pro-
grams, gaps or inadequacies in
these programs, areas of currently
unaddressed ground water issues,
recommendations for changes or
improvements in existing programs,
and institution of new programs
where needed.
    The Indiana Plan is an agenda
for State action to prevent, detect,
and correct contamination and
depletion of ground water
resources. The implementation  plan
identifies key steps, schedules,
responsibilities, resources, outputs,
and contingencies to accomplish
the objectives of the plan. This  plan
is to be  adaptable to new Federal
requirements, responsive to  emerg-
ing issues and proprieties, and sub-
ject to revision based on experience.
    As of January 1994, 8 of the 23
Nebraska Natural Resource Districts
had developed local Ground Water
Protection plans, including

•  Stated goal to maintain ground
water levels and quality at
predevelopment levels forever

•  Development of Ground Water
Control areas with mandated
permitting, spacing, and reporting
requirements
 • Development of Special Protec-
 tion areas with required education,
 monitoring, and regulatory pro-
 grams to reduce nonpoint source
 contamination

 • Development of Ground Water
 Management Plans

 • Development of Ground Water
 Quality Management Areas to man-
 age nitrogen fertilizer application
 and irrigation practices.

 Ground Water Protection
 Standards

    Although many States and
 Tribes use Federal drinking water
 standards to direct their ground
 water protection activities, a
 number have tailored the standards
 to meet their specific conditions.
 State and Tribal ground water
 protection standards may be either
 narrative or numeric. Numeric
 standards set health-based maxi-
 mum contaminant levels (MCLs) for
 specific compounds  in ground
 water. Narrative standards-are
 adopted for contaminants for which
 numeric standards have  not been
 adopted. Forty-one States, Territo-
 ries, and Tribes reported the devel-
 opment or implementation of
 ground water protection standards.
    All ground water in South Caro-
 lina is classified  as Class GB, which is
 ground water that meets the defini-
 tion of an underground source of
 drinking water (USDW). All USDW
 supplies must have contaminant
 levels that are below MCLs set forth
 in the South Carolina Primary Drink-
 ing Water Regulations. Compounds
for which standards  or proposed
 MCLs do not exist are evaluated
 individually.

                                         Arizona's Aquifer Water Quality
                                     Standards are the cornerstone of the
                                     State's ground water protection
                                     program. All aquifers were initially
                                     classified and protected for drinking
                                     water use, and none has been re-
                                     classified. Numeric Aquifer Water
                                     Quality Standards were developed
                                     and adopted by Arizona as enforce-
                                     able standards for the maximum
                                     permissible level of a parameter in a
                                     public water system. The Arizona
                                     Department of Environmental Qual-
                                     ity has also adopted  narrative
                                     aquifer water quality standards that
                                     allow regulation of pollutant dis-
                                     charges for which  no numeric stan-
                                     dards have been adopted.
                                         Standards for ground water
                                     quality in Nebraska are intended to
                                     be the foundation for ground water
                                     point source programs in the State.
                                     Narrative standards deal primarily
                                     with beneficial uses of ground
                                     water. Beneficial uses of ground
                                     water, hydrologically connected
                                     ground waters, and surface waters
                                     are all protected. Numeric standards
                                     in the form of MCLs for various
                                     parameters are  also provided. Some
                                     parameters listed are assigned
                                     "reserved status."  This means that
                                     ground water standards have not
                                     been adopted for these parameters
                                     but will be in the future.
Ground Water
Classification/Mapping
Programs

    Forty-two States, Territories, and
Tribes have developed or are devel-
oping ground water classification
systems to aid in the protection and
management of their aquifers.
Classification  systems can be used as
a basis for the maintenance and
restoration of ground water quality,
the development of ground water
quality standards,  and land use and
pollution source management and
regulation. Most ground water clas-
sification systems are based on the
understanding that some human
activities have the potential to
degrade ground water. The systems
are designed  to restrict such  activi-
ties to  areas overlying aquifers con-
taining lower quality waters while
protecting the most vulnerable and
ecologically important ground water
systems. Most States and Tribes that
have classification systems apply
them to the permitting of dis-
charges or potential discharges to
ground water and the remediation
of contaminated ground water.
Some States may  also use their
systems to guide the development
of new water supplies or to site
certain types  of industries.
    The first tiers of a State's classifi-
cation  system are  typically designed
to identify and protect water that is
currently used or has the potential
to be used as a source of drinking
water.  The potential for drinking
water use is generally based  on
water quality indicators, such as
salinity and total dissolved solids,
and potential yield.  Some States
and Tribes also place ecologically
sensitive aquifers in the highest tiers
of their classification systems.

                                                          Chapter Eighteen Ground Water Protection Programs   459
    Aquifers that do not meet these
requirements or that are unsuitable
for use because of poor ambient
water quality or because of past
contamination are generally classi-
fied for other types of uses, such as
industrial processes or,  in some
cases, waste disposal.
    The New Jersey Department of
Environmental Protection and
Energy has classified the State's
ground water on a regional basis
according to its hydrogeologic char-
acteristics and designated uses. The
State has applied a nondegradation
policy to the most sensitive ecologi-
cal area but allows minimal degra-
dation in some  other areas, recog-
nizing that some human activities
will adversely affect ground water.
    In 1992, Michigan  State Univer-
sity Center for Remote  Sensing
mapped aquifer vulnerability to
surface contamination for use in
siting facilities or activities with a
potential for ground water contami-
nation. The most vulnerable areas
constitute 31 %  of the State's land
area and are composed of highly
permeable  soils over highly sensitive
glacial drift, principally  composed of
sand and gravel (Figure 18-3). The
moderately and least vulnerable
areas make up 44% and 25% of the
State, respectively.
     As part of the development of
a ground water classification system,
the recharge areas for major aqui-
fers in Rhode Island as well as
approximately 450 sources of
known and potential sources of
ground water contamination have
been mapped. The Rhode Island
Department of Environmental Man-
agement (DEM)  has made extensive
use of the Rhode Island Geographic
Information System (CIS) in this
mapping. Maps can be produced
with the CIS at different scales, in
various formats, and with different
layers of information. DEM encour-
ages the use of these maps in local
ground water protection efforts.
    The lack of a classification
system does not indicate a lower
priority for ground water protection.

I	!	'
The majority of States, Territories,
and Tribes that do not have explicit
classification systems apply the same
level of protection to all aquifers,
with either a statewide antidegra-
dation policy or the preservation of
all ground water for drinking water
use. For example,  Minnesota does
not employ a classification system.
However, the State supports a
nondegradation policy, promoting
preventive measures to protect all
ground water from degradation by
human activities.

Wellhead Protection
Programs

    The 1986 Amendments to the
Safe Drinking Water Act (SDWA)
established the WHP Program.
Under SDWA Section  1428, each
State must prepare a WHP Plan and
submit it to EPA for approval. By the
end of April 1995, a total of 39
States had EPA-approved WHP
Programs in place.
    Six cases of benzene contamina-
tion were detected in public water
supplies in Louisiana in 1992.
Louisiana's WHP Program aided the
communities in locating the sources
of contamination and in  the siting
of new wells. Case studies of these
communities prompted a coordi-
nated effort between the WHP Pro-
gram and the  Louisiana Department
of Environmental Quality
Underground Storage Tank (UST)
Division to see that all unregistered
USTs are registered and all aban-
doned USTs within a 1,000-foot
radius of public water supply wells
are closed. This restrictive radius will
increase with time.
Coordination of
Protection Programs
Among State Agencies

    Historically, ground water pro-
tection programs have been over-
seen by many different agencies
within the States, Territories, and
Tribes,  making coordination difficult
for those programs. Coordinating
the activities of these agencies to
ensure  an efficient ground water
protection program has become a
top priority in many jurisdictions.
Fifty-one States, Territories, and
Tribes report having developed a
plan to coordinate  ground water
protection programs among their
agencies.
    The Illinois Ground Water Pro-
tection Act (IGPA) created the
Interagency  Coordinating Commit-
tee on  Groundwater (ICCG) to
direct efforts of State agencies and
expedite implementation of ground
water protection efforts. Ten State
agencies actively participate in the
ICCG. In order to direct overall
comprehensive ground water pro-
tection efforts, the  ICCG established
the Governor-Appointed Ground-
water Advisory Council (GAC),
which is comprised of various inter-
est groups, including business,
industry, agriculture, regional plan-
ning, environmental, municipalities,
water well drillers, and public water
supplies.
    Ground  water  protection in
Colorado is a shared responsibility
of many agencies at all  levels of
government. Colorado authorized
four "implementing" agencies as
partners in ground water protection:
Mined  Land Reclamation Board, The
Oil and Gas  Commission, the State
Engineer (Division of Water
Resources), and the Hazardous

 Materials and Waste Management
 Division of the Health Department.
 Each of the implementing agencies
 has developed regulations to protect
 ground water within the area of
 authority with which each agency is
 charged, and they annually report
 their progress to the Water Quality
 Control Division, the agency with
 final authority for protecting the
 resource.

 Ground Water
 Monitoring Programs

    Two types of ground water
 monitoring programs are used by
 States to collect data on ground
 water quality: ambient monitoring
 and  compliance monitoring. Ambi-
 ent monitoring programs measure
 background or existing water qual-
 ity and are used to track long-term
 trends in contaminant concentra-
 tions. Compliance monitoring pro-
 grams are required by Federal or
 State regulations (e.g., ground
 water monitoring at site cleanups
 under CERCLA, detection monitor-
 ing under RCRA, or community
 water supply monitoring under
 SDWA). Compliance monitoring
 activities measure for specific con-
 stituents to ensure that their con-
 centrations in ground water are
 below regulated levels. In addition
 to ambient and compliance moni-
 toring, States may also rely on
 monitoring data collected by
 Federal agencies, such as the USGS
 National Water Quality Assessment
 program, to assess basin ground
water quality.
    Chemical or constituent-based
 indicators are generally used as part
of a monitoring program to define
trends in ground water quality. The
 constituent-based indicators used in
 each State are typically selected
 based on local or regional water
 quality, contaminant use characteris-
 tics, or previously observed contami-
 nation patterns. By identifying
 changes in the concentrations of
 these constituents in ground water,
 land uses affecting vulnerable aqui-
 fers can be identified and corrected.
    Administrative indicators are
 another form of indicator parameter
 that may be used by States. Admin-
 istrative indicators assess the status
 of potential sources of contamina-
 tion, such as the number of hazard-
 ous waste sites, the amount of
 leachable pesticides applied to land,
 the amount of toxic chemicals
 released annually, the number of
 abandoned water wells,  or other
 changes in regional land use prac-
 tices. These administrative indicators
 allow States to target their ground
 water protection and monitoring
 activities.
    Table 18-1 summarizes the
 types of indicators and monitoring
 programs that States and Territories
 currently use to measure ground
 water quality. Appendix  I, Table 1-2,
 presents this information in greater
 detail. Data were obtained from
 review of 305(b) reports, monitor-
 ing program documentation, and
 contact with State officials. For con-
flicting sources, the most recent
 information is presented and the
source is cited.
    Virtually all of these States
engage in some type of ground
water quality monitoring program.
Specifically, 23 States report active
ambient monitoring programs.  In
addition, Colorado and Nevada
have proposed ambient monitoring
programs. Sixteen of these States

                                      Florida has focused the set of
                                      parameters monitored under their

                                      patterns and contaminant sources.
                                      In regions of high agricultural land
                                      use, Florida focuses on nitrate and

                                      Similarly, Florida analyzes for certain
                                      trace metals (e.g., arsenic, barium,
                                      cadmium, chromium, copper,
                                      mercury, nickel, silver, and zinc) in

                                      rotating basis.  Several States are also
                                      pursuing the use of indicators to
                                      screen for certain sets of water qual-
                                      ity parameters in their monitoring
                                      programs. For example, Idaho is
                                      developing the use of immunoas-
                                      says to assess the presence of pesti-
                                      cides in  ground water.  Idaho uses
                                      the immunoassay methods to ana-
                                      lyze specifically for 2,4-D, alachlor,
                                      carbamate, carbofuran, cyanazine,
                                      metalachlor, and triazines.
                                          In addition to ambient monitor-
                                      ing, 31 States  report that they also

                                      ing activities to assess trends in
                                      ground water quality, and 18 use
                                      Federal monitoring data.
                                          A total of 18 States use adminis-
                                      trative indicators to track potential
                                      sources of contamination. Of these
                                      18 States, 13 use indicators that
                                      were suggested by EPA in its
guidance document for the 305(b)
Water Quality Report to Congress.
These indicators include MCL viola-
tions, point sources of pollution
(e.g., underground storage tanks,
military bases, RCRA, CERCLA, and
other hazardous waste  sites), nitrate
contamination,  and pesticide  use.

Federal Programs
    The Federal Government has
instituted laws and programs to
provide a framework to States, Terri-
tories, and Tribes for protection of
our Nation's ground water
resources. These include Federal
statutes that mandate certain
ground water protection activities
and EPA programs that deal
specifically with the control of con-
taminant source activities conducted
under the authority of Federal stat-
utes. Federal statutes include the
Safe Drinking Water Act, the Clean
Water Act, the Resource Conserva-
tion and Recovery Act, the Compre-
hensive Environmental Response,
Compensation, and Liability Act, the
Toxic Substances Control Act, the
Federal  Insecticide, Fungicide, and
Rotenticide Act, and the Pollution
Prevention Act.
    Under these Acts, the  EPA is
responsible for 20 programs related
to ground water protection. Most of
these are regulatory programs that
restrict or prevent specific  activities
from introducing contaminants onto
the land, into the subsurface, or
into ground water resources. The
rest are nonregulatory and provide
national guidance and technical
assistance to jurisdictions to identify
and protect their vulnerable ground
water resources and integrate exist-
ing ground water protection

programs. Both types of programs
are key components of EPA's suc-
cessful ground water protection
strategy when building partnerships
with other EPA programs, Federal
agencies, State and local govern-
ments, industry, environmental
groups,  and the regulated commu-
nity. Several concepts fundamental
to this approach to ground water
protection are based on EPA's guid-
ing principles: ecosystem protection,
environmental justice,  pollution
prevention, strong science and data,
partnerships, and compliance. They
are:

•  Review regulations for opportuni-
ties to get better environmental
results at less cost; improve new
rules through increased coordina-
tion.

•  Actively promote pollution pre-
vention  as a standard business prac-
tice and a central ethic of environ-
mental protection.

•  Make it easier to provide, use,
and publicly disseminate relevant
pollution and environmental infor-
mation.

•  Assist companies that seek to
obey but exceed legal requirements
and consistently enforce the law
against those that do not.

•  Change permitting  so that it
works more efficiently, encourages
innovation, and creates more op-
portunities for public participation.

•  Give  industry the incentives and
flexibility to develop innovative
technologies that meet and exceed
environmental standards while cut-
ting costs.
    Highlights of a number of Fed-
eral ground water protection pro-
grams are presented according to
the following protection categories:
resource protection, pollutant source
control, and pollution prevention.

Resource Protection

    The protection of the Nation's
ground water resources is addressed
under the Clean Water Act and the
Safe Drinking Water Act. The CWA
encourages ground water protec-
tion, recognizing that ground water
provides a significant proportion of
the base flow to streams and lakes.
Ground water protection afforded
by the SDWA is focused on waters
that supply public water systems
(PWSs), and through implementa-
tion of the Wellhead Protection and
Underground Injection Control
Programs.

Clean Water Act

    In the CWA (Public Law 92-500)
of 1972 and in the CWA Amend-
ments of 1977 (Public Law 95-217),
Congress provided for the regula-
tion of discharges into all navigable
waters of the United States. Ground
water protection  is addressed in
Section 102, providing for the de-
velopment of Federal, State, and
local comprehensive programs for
reduction, elimination, and
prevention of ground water
contamination.
    As part of the CWA, a process is
established that allows for the gen-
eration of information concerning
the quality of our Nation's ground
water resources and the reporting  of
this information to EPA and the U.S.
Congress. The requirements for this
process are found in Sections 106(e)

466   Chapter Eighteen Ground Water Protection Programs
                                     and 305(b) of the CWA. Section
                                     305(b) mandates that States
                                     develop a program to monitor the
                                     quality of their waters and report
                                     the status in this biennial National
                                     Water Quality Inventory Report to
                                     Congress. This process, referred to
                                     as the 305(b) process, is the princi-
                                     pal means by which the EPA, Con-
                                     gress, and the public evaluate water
                                     quality, the progress made in main-
                                     taining and restoring water quality,
                                     and the extent to which problems
                                     remain.
                                         Unfortunately, information
                                     reported on the quality of our
                                     Nation's  ground water resources has
                                     not always provided a complete and
                                     accurate  picture of overall ground
                                     water quality. This is due, in part, to
                                     the expense involved in collecting
                                     ground water monitoring data, the
                                     complex spatial variations of aquifer
                                     systems across the Nation, and the
                                     differing  levels of sophistication
                                     among State programs. Recognizing
                                     this problem, EPA worked with
                                     States to develop guidelines for the
                                     comprehensive evaluation and
                                     reporting of ground water quality.
                                         Appreciating that data collec-
                                     tion and  organization vary among
                                     the States and that a single data
                                     source for evaluating ground water
                                     quality does not exist, EPA
                                     suggested several different sources
                                     of data that may be used by States
                                     to evaluate their ground water qual-
                                     ity. EPA then encouraged States to
                                     use available  data that they believe
                                     reflects the quality of the resource.
                                     EPA also  focused on allowing States
                                     to report information for aquifers or
                                     hydrogeologic settings that are a
                                     State priority due to high ground
                                     water demand or vulnerability.
                                     Using these guidelines, States will be
able to provide a more meaningful
interpretation of ground water qual-
ity-

Comprehensive State Ground
Water Protection Program

    Under the authority of the CWA
Section 102, many States are devel-
oping Comprehensive State Ground
Water Protection Programs tailored
to their goals and priorities for the
ground water resource. CSGWPPs
will guide the future implementa-
tion of all State and Federal ground
water programs and provide a
framework for States to coordinate
and set priorities for all ground-
water-related activities.  Each
CSGWPP consists of six strategic
components: a goal, a priority-
setting mechanism, roles and
responsibilities, management
measures, information collection
and management, and public
participation.
    The EPA is committed to work-
ing with States in developing and
carrying out the CSGWPP approach.
A State with an EPA-endorsed
CSGWPP works in partnership with
the EPA to further improve State
ground water protection activities,
develop a vision of integrated,
resource-focused ground water
protection, and identify ways that
the Federal Government can
support State ground water protec-
tion efforts.
    Figure 18-4 shows the progress
in  implementing the CSGWPP
approach. As of 1994, the EPA had
approved four State CSGWPPs, and
EPA endorsement is anticipated for
an additional six States in 1995.
Another 29 States are expected to
submit CSGWPPs for EPA approval
by the end of fiscal year 1996.

Safe Drinking Water Act

    The SDWA was passed by
Congress in 1974 and amended in
1986. Under this Act, EPA sets
national limits on contaminant levels
in drinking water to ensure that the
water is safe for human consump-
tion. The principal ground water
protection afforded by the SDWA
comes through the enforcement of
these limits  through State and
Federal supervision of public water
systems. The SDWA also contains
programs to implement the Well-
head Protection Program, the Sole
Source Aquifer (SSA) Program, and
the Underground Injection Control
(UIC) Program, described below.
    Approximately 93% of all PWSs
(177,589 systems serving nearly 114
million  people) obtain their water
from a ground water source. These
include systems that supply year-
round water to households (46,880
Community Water Systems); sys-
tems that provide water to places
such as schools, factories, and hos-
pitals (23,221  Nontransient
Noncommunity Water Systems);
and systems that supply water to
transitory customers such as camp-
grounds, motels, and gas stations
(107,488 Transient Noncommunity
Water Systems). Private, domestic
wells are not regulated under the
SDWA.

Drinking Water Standards

    EPA, under the SDWA, seeks to
ensure that  public water supplies
are free of contaminants that may
cause health risks and to protect
ground water resources by prevent-
ing the endangerment of under-
ground sources of drinking water.
EPA has  pursued a twofold
approach: (1) protecting drinking
water at the tap, and (2) preventing
contamination of ground water
sources of drinking water supplies.
    The 1986 Amendments to the
SDWA provided for an expanded
Federal role in protecting drinking
water, mandating changes in
nationwide safeguards, and new
responsibilities to enforce them in
the event of State inaction.
    EPA has also focused on the
prevention of contamination of

                                    addition, EPA has targeted specific
                                    activities  to protect drinking water

requirements for Class I  hazardous
waste wells and the imposition of
more restrictive standards for all
Class II oil and gas injection wells.

Wellhead Protection Program

   The 1986 Amendments to the
SDWA established the WHP Pro-
gram. Under SDWA Section 1428,
each State must prepare a WHP
Plan  and submit it to EPA for ap-
proval. The objective  of this pro-
gram is to protect public health
through local action to prevent
ground water contamination from
reaching public wells by (1) identify-
ing the areas around  public water
supply wells that contribute ground
water to the well, and (2) managing
potential sources of contamination
in these areas to reduce threats to
the resource.
    By the end of April  1995, a
total of 39 States and Territories had
EPA-approved WHP Programs in
place. Figure 18-5 illustrates the
States and Territories having regula-
tory  authority to implement WHP
programs. EPA is working with the
remaining States, Tribes, and Terri-
tories to help them develop WHP
Programs. EPA's Office of Ground
Water and Drinking Water is sup-
porting the development and imple-
mentation of WHP at the local level
through many efforts. For example,
EPA-funded support is provided
through the National Rural Water
Association (NRWA) Ground Water/
Wellhead Protection programs.
These programs are currently being
implemented voluntarily in 31
States. These States work to inte-
grate their local programs with the
WHP Program to meet State
requirements. Figure  18-6 presents

the States with active and pending
NRWA Wellhead Protection
programs.
    EPA is also funding Wellhead
Protection workshops for local deci-
sionmakers. Eighty-eight of these
workshops were held in 26 States.
These workshops were attended by
approximately 4,400 people.
    In 1991, EPA funded a 2-year
cooperative agreement with NRWA
to promote ground water protec-
tion. This agreement was extended
for an additional 2 years. At the
conclusion of the first 4 years, over
2,000 communities in 26 States
were actively involved in protecting
their water supplies by implement-
ing wellhead protection programs.
These 2,000 communities represent
3,985,000 people in the rural areas
of the United States who will have
better-protected water supplies.
    EPA also funded a 3-year
cooperative agreement with the
League of Woman Voters (LWV) to
develop and test models of commu-
nity outreach in 18 communities.
Based on the experience in those
communities, a guidebook entitled
Protect Your Groundwater: Educating
for Action was developed. The
popularity of this guidebook led to
a national videoconference of the
same name.  Broadcast in April 1994
to over 150 sites, the video-
conference directly  reached approxi-
mately 3,000 persons. Videotapes
were made of the conference and
distributed to LWV chapters across
the country. The success of this
videoconference has led to further
cooperation with LWV to bring
WHP to  even more communities.
    According to State 305(b)
reports, WHP Programs have taken
varying forms in the different States.
Among the stages of WHP Program
development reported by States are
•  Grants to communities to explore
and tailor WHP approaches to their
needs

•  Mapping of sensitive ground
water protection areas

•  Establishment of mandatory WHP
programs to protect public water
supply wells

•  Establishment of public  education
and outreach programs

•  Establishment of specific protec-
tion criteria for wells tapping con-
fined aquifers and  more stringent
protection criteria for wells tapping
unconfined aquifers.

                                      Sole Source Aquifer Program

                                          The Sole Source Aquifer protec-
                                      tion program was established under
                                      Section 1424(e) of the SDWA of
                                      1974. The program allows commu-
                                      nities, individuals, and organizations
                                      to petition EPA to designate aquifers
                                      as the "sole or principal" source of
                                      drinking water for an area. Since
                                      the  first SSA designation in 1975—
                                      the  Edwards Aquifer in the area
                                      around San Antonio, Texas—64
                                      designations have been made
                                      nationwide. Seven petitions were
                                      evaluated for possible designation at
                                      the  end of 1994.
                                          If the sole-source designation is
                                      approved for an aquifer, EPA is then
                                      authorized to review all Federal
                                      financially assisted projects to deter-
                                      mine if, as a result of the project,
                                      the  potential exists for adverse
                                      impacts to public health due to
                                      aquifer contamination. If the Federal
                                      financially assisted project is
                                      approved by EPA, the project may
                                      be implemented as planned with
                                      commitment of Federal financial
                                      assistance; however, if the potential
                                      exists for aquifer contamination,
                                      modifications to the project may be
                                      necessary prior to commitment of
                                      Federal financial assistance. Federal
                                      funds may be used to make these
                                      modifications to ensure that
                                      projects will not contaminate the
                                      aquifer.
                                          Federal financially assisted
                                      projects undertaken in SSA areas
                                      may include a variety of activities
                                      involving several agencies. For
                                      instance, approximately 50% of the
                                      reported activities were initiated by
                                      Housing and  Urban Development
                                      (HUD) through Community Devel-
                                      opment Block Grants. These include
                                      the construction of nursing homes,
repair and construction of firehouses
to avoid hydrocarbon runoff from
equipment from entering the
ground water, and installation of
septic systems using proper non-
polluting drainage construction. The
Department of Agriculture Farmers
Home Administration  has invested
in construction and  preplanned
siting programs for residential areas
and ancillary facilities on a large
scale.
    The Department of Transporta-
tion assists in funding construction
of roads, highways,  mass transit,
and certain railroad  and airport
facilities. This type of construction
requires that the proper disposal of
surface water runoff be dispersed
rather than concentrated on the
ground surface and avoid the flood-
ing of local aquifers by runoff from
salting stations, hydrocarbons from
highway spills and general traffic
use, including airports and hangar
areas.
    Designation  helps project spon-
sors by providing a set of guidelines
for aquifer quality review and
ground water protection techniques.
It also allows individuals, agencies,
and States and Tribes the opportu-
nity to develop strategies beyond
the SSA program to protect drinking
water aquifers, such as adopting
Wellhead  Protection Programs.
    Figure 18-7 illustrates the num-
ber of projects reviewed, approved,
and modifed for fiscal years  1990
through 1994. Only five projects
were not approved during this same
period: four projects in 1991  and
one in 1992. There were no other
unapproved projects after 1992.
This curtailment is an indication that
SSA project sponsors have adjusted
to the ongoing SSA ground  water
protection program objectives.

    Review of Figure 18-7 indicates
 the following:

 • A total of 1,039 projects were
 reviewed over the 5-year period.
 Of these, 838 were approved and
 74 were modified.

 • Review of project modifications
 indicates that ground water protec-
 tion was achieved through changes
 in drainage and spill containment,
 clear identification of SSA bound-
 aries,  more focused pre- and
 postconstruction activity monitoring,
 and review of initial project designs.

 • For fiscal years 1992,  1993, and
 1994, project modifications
 decreased by approximately 64%
 over previous years. This decrease
 reflects the maturing  of the SSA
 program as a community ground
 water protection tool. Project spon-
 sors and designers acknowledge
 that proper aquifer protection is
 required up front in the design
 phase and that incorporation of
 proper aquifer protection will expe-
 dite designations.

 Pollutant  Source Control

    Four principal programs control
pollutant sources under four differ-
ent laws: underground storage
tanks and solid and hazardous waste
treatment, storage, and disposal are
regulated under RGRA; underground
injection of waste fluids is regulated
under SDWA;  abandoned waste is
regulated under CERCLA; and
nonpoint sources are controlled
under CWA.
 Resource Conservation and
 Recovery Act

    The Resource Conservation and
 Recovery Act (Public Law 94-580)
 was passed by Congress in October
 1976, amending the 1965 Solid
 Waste Disposal Act to  address the
 problem of safe disposal of the huge
 volumes of solid and hazardous
 waste generated nationwide each
 year. This Act authorizes a regula-
 tory program to identify and man-
 age wastes that pose a substantial
 hazard to human health or the envi-
 ronment. RCRA is a part of EPA's
 comprehensive program to protect
 ground water resources. Protection
 is achieved through the develop-
 ment of regulations and methods
for handling, storing, and disposing
of hazardous material and through
the regulation of underground stor-
age tanks.

among State ground water con-
tamination concerns. Of the quarter
million solid waste disposal facilities
in the United States, about 6,000
are municipal solid waste facilities.
Approximately 25% of these
municipal facilities have ground
water monitoring capabilities.
    As of September 1994, there
were 418 land disposal facilities
subject to ground water monitoring
requirements under RCRA. Approxi-
mately 221 of these facilities are
conducting detection monitoring,
42  are conducting compliance
monitoring, and 155 are undertak-
ing corrective action.

Solid and Hazardous Waste

    RCRA has evolved from a rela-
tively limited  program dealing with
nonhazardous solid waste to a far-
reaching program that also encom-
passes the handling, storage, and
disposal of hazardous waste. Haz-
ardous waste generators, transport-
ers, and owner/operators of treat-
ment, storage and disposal facilities
(TSDFs) constitute the RCRA-
regulated community. On Novem-
ber 8, 1984,  Congress  passed the
Hazardous and Solid Waste Amend-
ments (HSWA) to RCRA, thereby
greatly expanding the nature and
complexity of activities covered
under RCRA.
    The goals of RCRA, as set forth
by Congress, are

• To protect human health and the
environment

• To reduce waste and conserve
energy and natural resources

• To reduce or eliminate  the
generation of hazardous waste as
expeditiously as possible.
    RCRA also requires the promul-
gation of standards related to
underground storage tank systems
for both chemicals and petroleum
products.
    In 1990 and 1991, RCRA pro-
grams continued to emphasize the
preparation of risk assessment docu-
ments and development and
evaluation of tests and procedures
for conducting risk assessments.
Health and Environmental Effects
Documents, Reference Doses, and
technical evaluations are provided
to support the RCRA waste listing,
permitting, and land disposal restric-
tion programs'. The  1990 program
emphasized the development of
health and environmental effects
documents for the listing/delisting
programs and reference doses for
the land disposal  restriction pro-
gram. In addition, techniques for
determining soil gas concentrations
and constituents and for determin-
ing ground water contamination
potential were evaluated under field
and laboratory conditions. Guide-
lines for monitoring ground water
around RCRA Subtitle D landfill
facilities are being developed.

Underground Storage Tank
Program

     One of the primary goals of this
program is to protect the Nation's
ground water resources from
releases by underground storage
tanks containing  petroleum or cer-
tain hazardous substances. The EPA
works with State  and local govern-
ments to implement Federal require-
ments for proper management of
USTs. The EPA estimates that about
 1.2 million federally regulated USTs
are buried at over 500,000 sites
• nationwide. Nearly all USTs contain
 petroleum; about 30,000 USTs hold

                                                          Chapter Eighteen Ground Water Protection Programs  473
 hazardous substances covered by
 the Federal regulations.
    In 1988, EPA issued regulations
 setting minimum standards for new
 tanks (those installed after Decem-
 ber 22, 1988) and existing tanks
 (those installed before December
 22, 1988). By December 1998,
 existing USTs must be upgraded to
 meet minimum standards or be
 replaced with new tanks or be
 closed properly. Since 1988, more
 than 900,000 old USTs have been
 closed, thus eliminating a significant
 number of potential sources of
 ground water contamination. Of the
 remaining 1.2 million USTs, about
 400,000 have already been
 upgraded or replaced.
    New and existing USTs comply-
 ing with EPA's standards can pre-
 vent leaks caused by spills, overfills,
 corrosion, and faulty installation.
 USTs complying with the leak
 detection requirements can identify
 releases quickly, before contamina-
 tion spreads. Corrective action
 requirements secure responsible and
 timely cleanup of contaminated
 sites.
    As of January  1995, more than
 278,000 UST releases had been
 confirmed. The EPA estimates that
 about half of these releases have
 reached ground water.  Over
 110,000 contaminated sites have
 been cleaned up,  and cleanups are
 under way at 100,000 more sites.
 EPA estimates that the total number
 of confirmed releases could reach
400,000 in the next several years,
 primarily due to releases discovered
during the closure or replacement
of old USTs. After this peak, EPA
expects fewer releases as USTs
comply with leak prevention re-
quirements.
   Congress created the Leaking
Underground Storage Tank (LUST)
 Trust Fund in 1986 to provide
 money for overseeing corrective
 action taken by a responsible party
 and to provide money for cleanups
 at UST sites where the owner or
 operator is unknown, unwilling, or
 unable to respond or that require
 emergency action. Since 1986,
 $469 million has been dispersed to
 State UST programs for  State
 officials to use for administration,
 oversight, and cleanup work.
     UST owners and operators must
 also meet financial responsibility
 requirements that ensure they will
 have the resources to pay for costs
 associated with cleaning up releases
 and compensating third parties. The
 amount of coverage required ranges
 from $500,000 to $1  million,
 according to the type and size of
 the UST business. Many States have
 provided financial assurance funds
 to help their UST owners meet the
 financial responsibility requirements.
 These State funds raise over $1 bil-
 lion  annually for use on  UST
 cleanups.
    The Agency recognizes that,
 because of the large size and great
 diversity of the regulated commu-
 nity, State and local governments
 are in the best position to oversee
 USTs. EPA encourages States to seek
 State program approval so they may
 operate in lieu of the Federal
 program. To date, 20  States have
 received State Program Approval. All
 States have UST regulations and
 programs in place. The Agency also
 has developed a data management
system that many States use to
track the status of UST facilities,
including their impact on ground
water resources. EPA also has nego-
tiated UST grants with all States and
provided technical assistance  and
guidance for implementation and
enforcement of UST regulations.

                                         EPA's UIC program was devel-
                                      oped to regulate underground injec-
                                      tion wells and thereby ensure that
                                      underground  sources of drinking
                                      water are protected. Injection wells
                                      are classified as follows:

                                      • Class I: Wells used to inject haz-
                                      ardous substances or industrial and
                                      municipal waste beneath the lower-

                                      of drinking water. There are 159
                                      hazardous waste wells at 61 facilities
                                      and 350 nonhazardous waste wells
                                      at 197 facilities controlled by strin-
                                      gent design, construction,  and oper-
                                      ating requirements. The hazardous

                                      billion gallons of fluids each year.

            Wells as  Conduits of Contamination

       Although anecdotal cases abound of wells serving as conduits that
   allow contaminants to enter an aquifer, few occurrences are docu-
   mented. However, the publication Drinking Water: Safeguards Are Not
   Preventing Contamination From Injected Oil and Cos Wastes (GAO, 1989)
   provides a table of 23 documented cases of contamination of an
   underground source of drinking water via Class II oil and gas injection
   wells. Fourteen of these cases resulted from wells that were improperly
   plugged or constructed and/or had leaky casings. Nine other cases
   were the result of deliberate injection into an aquifer before its designa-
   tion as an underground source of drinking water. What is particularly
   noteworthy in these cases is the enormous cost of cleanup. In one of
   the'cases, the State (Kansas) authorized $300 million to begin cleanup
   because the contamination  threatened a major municipal well field.  In
   18 of the other cases, no cleanup is intended because it is either
   impractical or too costly.
hazardous waste that is land

•  Class II:  Wells used to inject
fluids in the process of oil or natural
gas production. More than  160,000
disposal and enhanced recovery
wells inject brines into geologic
formations. These wells inject
approximately 3 billion gallons of
produced brine and enhanced
recovery fluids every day.

    Together Class I and II  injection
wells dispose of a larger volume of
hazardous waste into deep  bedrock
formation than all the other RCRA
hazardous waste disposal facilities by
a factor of eight.

•  Class III:  Wells used to inject
fluids for the purpose of in  situ
mineral extraction.

•  Class IV:  Wells used to dispose of
hazardous or radioactive waste into
or above an underground drinking
water source. These wells are
banned.

•  Class V:  Class V injection wells
are generally shallow wastewater
disposal wells, stormwater,  and agri-
culture drainage systems or other
devices that can release nutrient and
toxic fluids into the ground and
eventually into water table  aquifers.
EPA estimates that more than 1
million Class V wells currently exist
in the United States. A majority of
Class V wells may pose little or no
risk to human health. Others, how-
ever, may inject fluids containing
bacteria, viruses, nitrate-nitrogen,
and toxic chemicals that can con-
taminate the habitat and food sup-
ply of fish and wildlife species, the
base flow for surface waterbodies,
and the public drinking water sup-
ply. These wells include more than

 100,000 shallow injection wells such
 as those used to dispose of waste
 from automotive service bays.

     Currently, all shallow injection
 wells that do not endanger under-
 ground sources  of drinking water
 are allowed; however, because of
 the diversity in the risks posed by
 Class V wells and the size and
 nature of the regulated  community,
 EPA encourages a nontraditional
 regulatory approach to  addressing
 these wells. A large proportion of
 the Class V wells are owned by
 small businesses. To  effectively

 posed by the Class V universe, EPA
 is implementing a comprehensive
 strategy for the  management of
 Class V injection wells. The strategy
 involves a carefully tailored combi-
 nation of guidance, education, and
 outreach and enhancing the use of
 existing regulatory authorities
 through some minor changes to the
 UIC  regulations.  The goal of the
 strategy will be to speed up the
 closure of potentially endangering
 Class V wells using current authori-
 ties and to promote  the use of best
 management practices to ensure
 that other Class  V wells  do  not
 endanger USDWs.
    Grants allotted under Sections
 1443(b) and 1451 of the SDWA
 may be used to  support UIC activi-
 ties to protect ground water
 resources. State and  Federal UIC
 programs include permitting and
 review of permits to  ensure that
wells meet requirements for well
construction, operation,  monitoring,
 plugging, and abandonment, and
financial responsibility to ensure that
underground sources of drinking
water are not endangered. Section
 1422 provides EPA with  authority to
 grant primary enforcement authority
 (primacy) to States to administer a
 UIC program in their States. Section
 1425 allows an alternative test for
 EPA to use to approve a State's UIC
 program for Class II brine disposal
 wells.
     EPA and States currently admin-
 ister 57 UIC programs to maintain
 regulatory coverage of the almost
 one-half million  underground  injec-
 tion wells. The majority of these
 programs are State-administered, as
 depicted in  Figure 18-8. State agen-
 cies with primary enforcement
 authority respond to UIC violations.
 If a response cannot be made in a
 timely manner, EPA takes enforce-
 ment action.
     In 1992 and 1993,  EPA contin-
 ued to review "no migration"  peti-
 tions for hazardous waste injection
 wells to ensure conformance with
 RCRA and UIC provisions. EPA has
 targeted specific enforcement, out-
 reach, and regulatory activities to
 protect drinking water sources from
 the harmful effects of injections of
 wastes and other fluids through the
 vast number of diverse Class V
 injection wells. The Class V rule has
 significant implications for the  dis-
 posal of industrial wastes. EPA  also
 plans to propose "area of review"
 requirements for all Class II wells.
    EPA Regional office:; administer-
 ing UIC programs in nonprimacy
 States continue to review permit
 applications for injection wells  and
 continue oversight of State primacy
 programs to ensure that UIC per-
 mits issued meet program require-
 ments. Regional  offices also
 continue to  review petitions from
 operators of hazardous waste
 injection wells seeking exemptions
from the injection well ban.

beneficial uses, wherever possible,
within a time frame that is reason-
able given the  particular circum-
stances of the site. Following are
statistics related to Superfund resto-
rations:

•  In the absence of Superfund,
11.9 million people could be
exposed to carcinogenic risk greater
than 1  in a million, and 9.9 million
people could be exposed to noncar-
cinogenic effects above health-based
standards at National Priority List
(NPL) sites.

•  At 94% of NPL sites where
ground waters were classified (426
of 453), the ground water is cur-
rently used or  potentially usable as
a source  of drinking water. This
suggests that only 6% of NPL sites
involving ground water contamina-
tion are classified as nonusable aqui-
fers (e.g., saline or nonpotable).

•  Of the 622  NPL sites reporting
ground water contamination near
the site, the ground water is cur-
rently used for private water sup-
plies at 42% of the sites and for
public supplies at  27% of the sites.

•  At the 67% of NPL sites where
ground water  is currently used for
drinking water purposes, the
ground water  is potentially threat-
ened by a migrating contaminant
plume.

•  Organic compounds are the pre-
dominant ground water contami-
nants for 89% of the sites for which
remedies for ground water contami-
nation have been  selected. Table
18-2 lists the most frequently de-
tected organic and inorganic con-
stituents reported at NPL sites.

•  Ground water contamination is
associated with 63% of the sites for

which remedies have been selected
(702 of 1,121).

• Generally, ground waters that are
currently used or are potentially
usable for drinking water supply are
being cleaned to  MCLs authorized
under the SWDA. However, in some
cases, more stringent State stan-
dards are used. At least 12 States
have promulgated cleanup stan-
dards for ground  water, including
Massachusetts, West Virginia,  Illinois,
Minnesota, Wisconsin, New Mexico,
Texas, Iowa, Nevada, South Dakota,
Wyoming, and Washington.

Pollution Prevention

    The Pollution Prevention Act of
1990 was enacted by Congress to
promote pollution prevention and
environmental protection goals.
Under this Act, the EPA Office of
Pollution Prevention and Toxics and
the U.S. Department of Agriculture
Cooperative State Research Service
have worked cooperatively to lead
the Nation in the development of
environmentally sound agricultural
policies. The Agriculture in Concert
with the Environment Program
promotes the use of sustainable
agriculture and the integrated man-
agement of nutrients, pesticides,
resources, and wastes to reduce the
risks of environmental pollution.
Grants allotted under this Act may
be used to fund outreach projects
involving education, demonstration,
and training in sustainable agricul-
tural practices that emphasize
ground water protection and reduc-
ing the excessive use of nutrients
and pesticides.
    Grants are also available under
this Act to support State and local
pollution prevention programs that
address the reduction of pollutants
across all environmental media: air,
land, surface water, ground water,
and wetlands. These grants may be
used to promote and coordinate
existing State pollution prevention
activities that focus on specific
media, to develop new multimedia
pollution prevention programs, to
develop mechanisms to measure
progress in multimedia pollution
prevention, and to conduct educa-
tion and outreach programs.

                                     Experience

                                         In late 1989, the Texas Water
                                     Commission targeted the city of El
                                     Paso, Texas, for a pilot project to
                                     protect the city's ground water. This
                                     pilot project marked the beginning
                                     of an innovative, volunteer-driven
                                     Wellhead Protection Program. A
                                     team of dedicated volunteers was
                                     coordinated through the El Paso
                                     Retired Senior Volunteer Program.
                                         Over a 3V2-day period, the
                                     23 senior citizen volunteers surveyed
                                     possible sources of ground water
                                     contamination around  all 138 public
                                     water wells that provide drinking
                                     water to the city of El Paso. They
                                     reviewed historical records, inter-
                                     viewed area residents, and
                                     conducted door-to-door surveys to
catalog potential threats to their
drinking water. The State estimated
that the volunteer effort saved
approximately $35,000, and
resulted in the identification of
approximately 20,000 potential
sources of pollutants near the water
wells.
   The El Paso pollution source
inventory formed the backbone of
the El  Paso Wellhead Protection
Program and resulted in a city ordi-
nance concerning the storage of
hazardous materials within the vicin-
ity of the public water wells. The
effort has recently been expanded
into Mexico, since the residents of
the adjacent Mexican city of Ciudad
Juarez also rely on drinking water
from the same aquifers.

Oregon's Volunteer
Well Water Nitrate
Testing Project

   The Oregon Department of
Environmental Quality sponsored  a
project to encourage residents to
test their well water for nitrate
levels. The project was conducted
from 1991 to 1993 and resulted in
volunteers testing a total of 1,600
wells.  The Oregon Ground Water

League of Women
Voters Ground Water

The League of Women Voters
(LVW) has sponsored a number of
volunteer-led ground water educa-
tion programs. The LVW in Rock-
ford, Illinois, surveyed residents con-
cerning their knowledge of water
supply and ground water contami-
nation concerns. Similar surveys
were conducted by the LVW in Red
Wing, Minnesota, and Salt Lake
City, Utah. The LWV of Enid, Okla-
homa, organized volunteers to con-
duct pollution source inventories
around the city's five water well
fields. Other LVW chapters have
developed videos, brochures, and
other educational materials concern-
ing ground water protection and
potential threats to ground water
quality.

                                    Protecting Our Drinking Water:
                                    The EPA's Source Water
                                    Protection Initiative
                                       Americans have long enjoyed
                                    the luxury of safe, affordable drink-
                                    ing water. A rising awareness of
                                    water pollution incidents, however,
                                    has caused people to be concerned
                                    about drinking water quality. Many
                                    communities have recognized that
                                    preventing the pollution of lakes,
                                    rivers, streams, and ground water is
                                    the key to ensuring the long-term
                                    safety of drinking water. This com-
                                    mon sense approach is known as
                                    source water protection.
                                       The Safe Drinking Water Act
                                    emphasizes monitoring and treat-
                                    ment to protect drinking water
                                    safety. However, protection  based
                                    on monitoring and treatment alone
                                    is not sufficient. Nearly all groups
                                    interested in drinking water safety
                                    see a need for stronger efforts to
                                    prevent pollution from entering
                                    drinking water sources rather than
                                    relying solely on water treatment to
                                    reduce health threats.
                                       The EPA encourages this preven-
                                    tion-oriented approach and is
                                    actively promoting the development
                                    of grass roots source water protec-
                                    tion activities. As part of the Source
                                    Water Protection Initiative, the EPA
                                    hopes to
• Restore the public's rights and
responsibilities to protect their
drinking water

• Raise public confidence in the
safety and quality of their drinking
water supply

• Reduce the cos1x_of_ providing
safe drinking water.

Wellhead  Protection
Programs

    Many States and communities
are currently promoting source
water protection, in Wellhead Pro-
tection (WHP) programs. The 1986
Amendments to the Safe Drinking
Water Act established the Wellhead
Protection Program to aid commu-
nities in protecting their drinking
water quality. Through wellhead
protection, communities  identify the
land areas that contribute ground
water to public water supply wells.
They then develop plans to manage
the potential sources of contamina-
tion  in those vulnerable areas,
thereby reducing the likelihood of
polluting the drinking water source.

Chapter Eighteen Ground Water Protection Programs   481


By the end of December 1 994,
a total of 37 States and Territories
had EPA-approved WHP Programs
in place. In addition, thousands of
local WHP initiatives have been
undertaken in communities across
the Nation. As of 1 993, approxi-
mately 3,800 communities that are
dependent on ground water for
drinking water had complete WHP
programs.
Expanded Source
Water Protection
Goals
The idea of wellhead protection
can apply to surface water supplies
as well. The EPA is encouraging
stronger watershed protection pro-
grams, through approaches avail-
able under the Federal Clean Water
Act, to protect surface waters used
for drinking water supplies. Source
water protection, for both ground
water and surface water, may offer
significant advantages to both drink-
ing water purveyors and consumers.
The EPA is planning a National
Source Water Protection Workshop
~

in 1 996. This workshop will provide
communities with the tools and

*

information needed to establish
source water protection programs.
The workshop will be televised and
will target communities that have
delineated their source water pro-
tection arpas and rarripH nut cnnrro
identification. The workshop will
also assist communities in moving
toward source management.
The EPA has also set the follow-
ing source water protection goals:
• By 1 997, establish a core network
of 10,000 communities with active
and comprehensive local WHP
programs in place.
• By 1 997, incorporate source
water protection and source
management as priority objectives
in projects requiring financial assis-
tance from other Federal programs.

• By 1 997, begin to expand source
water protection approaches to
communities reliant on surface
water for drinking water.

• By 2005, have 50% of all
community water supplies covered
by active and comprehensive local

source water protection programs.

   The sage adage that "An ounce
of prevention is worth a pound of
cure" is being borne out in the field
of ground water protection. Three
separate efforts to look at the cost
of prevention versus remediation
have found that there can be real
cost advantages to promoting
prevention of ground water con-
tamination in the public and private
sectors.
   The analysis of prevention in
Maine found that, for six large
municipal water systems with con-
tamination from salt storage, gaso-
line, landfill leachate, and industrial
solvents, costs for well replacement,
emergency supplies, water treat-
ment, and/or remediation ranged
from $500,000 to $1,500,000. Of
the 2,000 small water systems in the
State, perhaps as many as 70 are
contaminated. For six small systems,
remedial costs ranged from $6,000
to $155,000. Costs  for preventing
contamination in these cases were
estimated to be 1/1 Oth to 1/100th
of the costs of remediation for the
large systems and 1/5th to 1/1 Oth
for the small systems. Although
remediation is thus  more costly than
prevention, whether prevention is
more cost-effective in any particular
instance depends on the risk that a
water system without a particular
type of preventive measure would
need remediation and when any
costs of remediation would be
incurred.
   The State of Washington's Well-
head Protection Program found
that,  in a sample of small communi-
ties ranging in size from 300 to
5,000 people affected by such
contaminants as ethylene dibromide
(an agricultural fumigant), gasoline,
and trichloroethylene (TCE, a sol-
vent), costs for cleanup and/or a
new water supply ranged from
$40,000 to $1,800,000, with costs
continuing to be incurred. For a
larger city—Tacoma—where TCE
and other contaminants were found
in a wellfield in concentrations more
than 10 times the health  standard,
costs over the expected 18-year
cleanup period are estimated to be
$25 million.
   Washington's Wellhead Protec-
tion Program catalogued  the types
of costs associated with contami-
nated public water supplies and
found that they included

cities for remediating ground water
contamination was over $30 million,
with seven cities reporting costs
over $1 million and two reporting
impacts in the $1 0 to $20 million
range. Fourteen cases of ground
water contamination involving cor-
porations found that most busi-
nesses spent over $1 million, with
five spending from $5 million to
nearly $1 0 million. In addition to
the technical and engineering reme-
dial costs, a major corporate cost
was legal fees.

Costs and  Benefits  of
Water  Pollution  Control
Introduction
    Section 305(b) of the Clean
Water Act calls for States to prepare
estimates of the economic and
social costs necessary to achieve the
objectives of the Act. States are also
requested to report on the eco-
nomic and social benefits of these
achievements. None of the States,
Territories, and Tribes reporting on
their water quality programs
attempted to describe the full
extent of the economic costs and
benefits associated with water qual-
ity improvement. Thus, the costs
shown in this chapter are from the
U.S. Department of Commerce,
Bureau of Census, Pollution Abate-
ment Costs and Expenditures, 1992.
Pennsylvania and the District of
Columbia submitted expenditure
information on municipal waste-
water treatment, which is included
in this report as well.
  .  The benefits described in this
chapter are from many sources.
Information from the Sport Fishing
Institute, State reports, and EPA and
other Federal sources was used to
help measure environmental bene-
fits achieved.  It is important to
understand the impossibility of
measuring the total environmental
benefits of water quality improve-
ment. First, benefits are local and to
measure the benefits of cleaner
water in  each locality would be
impossible. Second, the methodol-
ogy does not exist to measure the
value of biodiversity or the value of
the oxygen produced by a healthy
ecosystem. Although these intrinsic
values are very important, they are
not measurable quantitatively or
monetarily. This chapter provides
some insight into the benefits of
water quality improvement found
throughout our Nation. When
economic benefits data are not
available, biological indicators are
used to show stream improvement.
The assumption is that, if the insect
life in the stream is improving,
eventually the fish will return and so
will recreation, which has an eco-
nomic value.

Costs of Water
Quality Improvement


   Estimates of the costs and bene-
fits of water pollution control are
shown in Table 19-1 derived from
President Clinton's Clean Water Act
Initiative: Analysis of Costs and Bene-
fits published in 1994. This table
shows the current and planned
expenditures associated with the
current implementation of the Clean
Water Act requirements. Private
sources are estimated to spend
roughly  $30 billion per year on
water pollution control, municipali-
ties spend about $23 billion per

                                       mately $500 million per year, State
                                       water programs spend $500 million
                                       per year, and Federal  agencies
                                       spend approximately  $10 billion per
                                       year. These total to a  range of $63
                                       billion to $65 billion per year spent
                                       on water pollution control.
                                          Since 1972, EPA has invested
                                       over  $64 billion in municipal waste-
                                       water treatment. State and local
                                       governments have contributed
                                       many more  dollars. In 1972, only
                                       42% of the  population was served
                                       by secondary or better municipal
                                       wastewater treatment facilities. By
                                       1992, this number had increased to
                                       more than 62% of the population.
                                       This achievement is impressive con-
                                       sidering that, during this time, both
                                       the Nation's population and the
                                       volume of pollution flowing through
                                       our sewer systems increased by
                                       nearly 30%.
                                          EPA has invested  appproxi-
                                       mately $1.4 billion since 1972 in
                                       maintaining State water quality
programs through grants funded
under Section 106 of the Clean
Water Act. The goals of the Section
106 program are to assist States,
Territories, and Tribes in establishing
and maintaining adequate measures
for preventing and controlling
surface and ground water pollution.
Other Federal agencies such as the
Corps of Engineers, the U.S.
Geological Survey, the Natural
Resources Conservation Service, and
the Fish and Wildlife Service have
contributed substantially to the
water pollution control efforts in this
country.
    Pennsylvania provided the most
complete set of data. Pennsylvania
reported that, during the past 5
years, new grants totaling more
than  $118.5 million  in Federal
funds were offered to Pennsylvania
municipalities for construction of
sewage treatment facilities. Actual
dollar expenditures under this Fed-
eral grant program during this  pe-
riod amounted to $261.3 million,

which includes expenditures from
grants made during prior years.
Funding from other Federal agen-
cies, including the Farmer's Home
Administration and the Department
of Commerce, has provided munici-
palities an additional $63.1 million
for facilities planning and adminis-
tration. State funds and grants
issued by the Department of Envi-
ronmental Resources (DER) and the
Pennsylvania Department of Com-
merce have provided municipalities
another $140.1 million for waste-
water treatment facilities in the
same 5-year period (Table 19-2).
These facilities, as they begin opera-
tion, represent a significant effort in
the cleanup of Pennsylvania's
waters.
    The District of Columbia esti-
mates the capital  cost for the Blue
Plains wastewater treatment plant at
about $600 million and operation
and maintenance costs at about
$110 million per year.
Benefits of Water
Quality Improvement

    Improvements in water quality
are valuable to all Americans. Mil-
lions of people enjoy recreational
activities like fishing, swimming, and
boating on waters where these pur-
suits might not be possible without
the control measures undertaken
under the Clean Water Act. Cleaner
water has reduced health risks to
people who swim and fish. Cleaner
water has contributed to more pro-
ductive commercial and recreational
fisheries in many parts, of the coun-
try. It has  lowered costs to agricul-
ture and to industries that would
otherwise  have to treat contami-
nated water before using it.  It has
also lowered costs to drinking water
systems that might otherwise have
to install additional treatment tech-
nologies.  Finally, cleaner water has

                                      to visit them.
                                          Notwithstanding these impor-
                                      tant and substantial benefits of
                                      clean water, EPA has not  quantified
                                      systematically all of the extra-
                                      ordinarily diverse improvements in
                                      water quality that have occurred
                                      since the Clean Water Act was
                                      passed, or that  may be attributable
                                      to the Act.  Moreover, such quantifi-
                                      cation must typically precede  the

                                      from improvements to water quality
                                      are  not measurable given existing
                                      data and analytic methods. The
                                      following discussion describes,
                                      nonetheless, some  of the benefits
                                      associated with water quality im-
                                      provements.

                                      Recreation

                                          Outdoor recreation is a lucrative
                                      business in the  United States.  Much
                                      of our outdoor  recreation activities
                                      depend on clean water. Sport
                                      fishing alone accounts for 1.3 mil-
                                      lion jobs and $19 billion in wages.*
                                      The Sport Fishing Institute (1994)
                                      estimates more than 50 million
                                      anglers spent more than  $24  billion
                                      on fishing trips  and equipment in
                                      1991. The Institute claims that
                                      freshwater fishing "generates nearly
                                      60% of the economic impacts
                                      within the sport fishing industry."
Expenditures of this magnitude
generated approximately $1 billion
in State sales taxes and more than
$2 billion in Federal income taxes.
    The sport fishing industry is
increasingly vocal about the need
for clean water programs. Fifty mil-
lion anglers, representing a signifi-
cant portion of the U.S. population,
receive direct benefits of improved
water quality.
    Eighty million Americans partici-
pate in outdoor (non-pool) swim-
ming. Local and State economies
are dependent on beach-related
recreating, whether at ocean or lake
beaches. In 1988, $1.3 to $5.4
billion was lost in the New York-
New Jersey area due to beach  clos-
ings resulting from water quality
health standard violations.

Commercial Fishing

    The value of U.S. commercial
fish landings is about $3.5  billion
annually and the industry's total
contribution to the GNP is about
$16.5 billion. Shellfish landings
represent 45% of this total. Nearly
87% of the value of U.S. finfish
landings are species-dependent on
near-coastal waters for breeding  and
spawning.'

Good Water Quality
Benefits the Economy

    Good water quality is important
for economic development. Compa-
nies that want to attract the best
workers often locate in areas that
are replete with parks and open
spaces, where air and water quality

are good, and where recreational
opportunities are abundant. These
amenities are essential for the qual-
ity of life required by today's
workforce.
   The Institute for Southern Stud-
ies published a study in October
1994 illustrating the relationship
between State economic growth
and environmental quality. What
this study shows is summed in a
quote from Dr. Stephen Meyer of
the Massachusetts Institute of Tech-
nology. Dr. Meyer concluded:
"States with stronger environmental
standards tended to have the higher
growth in their gross state products,
total employment, construction
employment, and labor productivity
than states  that ranked lower envi-
ronmentally." The study ranked
Louisiana last for jobs and environ-
mental quality. Eight other southern
States (along with Indiana, Ohio,
and Oklahoma) ranked among the
14 worst States in both categories.
Hawaii, Vermont, and New Hamp-
shire ranked among the top six
States for both jobs and environ-
mental quality. Six States ranked
among the top  12 in both catego-
ries: Wisconsin, Minnesota, Colo-
rado, Oregon, Massachusetts, and
Maryland.*
    There are industries that are
dependent on a  healthy, clean
water supply. These industries range
from the soft drink to the computer
chip industry. For these industries,
clean water is a valued economic
input. The cleaner the source water,
the less treatment the intake water
requires. These savings are then
passed on to their consumers.
    The following discussion illus-
trates how  various States and the
District of Columbia benefit from
improved water quality and
describes some of the actions they
are taking to rebuild the benefits
lost two and three decades ago.

Water Quality Benefits
Identified by States

Pennsylvania

    Improved water quality condi-
tions have enabled programs to be
undertaken to  reintroduce breeding
populations of bald eagle, osprey,
and river otter in Pennsylvania. The
Pennsylvania Came Commission's
Bald Eagle Recovery Project was
carried out from 1983 to 1989.
A total of 88 young eagles were
released from hatching sites in  the
upper Delaware and lower Susque-
hanna River basins. In addition,
eaglets were introduced to active
nests in northwestern Pennsylvania
to supplement populations in that
area. As a result of this  program,
13 bald eagle nests were found in
1992. All together, the nests pro-
duced 21 hatchlings. In 1993, a
record 16 pairs of bald eagles
attempted to nest in the Common-
wealth.  Even though some nests
were abandoned due to the March
blizzard,  15 eaglets were produced.
    Through cooperative projects,
over 100 osprey (fish hawks) were
hatched in  northeastern Pennsyl-
vania in the early 1980s to form the
nucleus of what has become a
viable breeding population in the
Poconos. In 1989, a hatching tower
was constructed, on the Hammond
Dam in Tioga County, which can
accommodate  up to 16 ospreys.
This project was  initiated in 1990

                                     the National Audubon Society, the
                                     U.S. Army Corps of Engineers, and
                                     researchers from East Stroudsburg
                                     University and the Dubois Campus
                                     of Penn State University. In 1992, as
                                     many as 14 active osprey nests were
                                     located in the State. Nine were  in
                                     the Poconos, three were in
                                     Lancaster County,  and one each
                                     was in York and Somerset Counties.
                                         River otter reintroductions
                                     began in 1982. From 1982 through
                                     1989, 39 otters were released in the
                                     Kettle, Pine, and Loyalsock Creek
                                     basins in north central Pennsylvania.
                                     These otters have expanded their
                                     range and reproduced. Otter rein-
                                     troductions  in northwestern Pennsyl-
                                     vania began with the release of four
                                     otters in the Tionesta Creek basin in
                                     1990. More otters were scheduled
                                     to be released in this basin during
                                     1991. An April 1992 otter release in
                                     the Youghiogheny River brought
                                     them back to the drainage for the
                                     first time in  more than 100 years.
                                     Five otters were released near
                                     Confluence  as part of a  cooperative
                                     program. Additional releases are
                                     planned. In  addition, Maryland
                                     stocked 18 otters on the Youghio-
                                     gheny near  Oakland in 1989 and
                                     1990. The success of these
                                     programs is due, in part, to
                                     improved water quality and result-
                                     ing improved fisheries.
                                         The following  are estimates
                                     of the economic value of fishing
                                     and boating to the Pennsylvania
                                     economy. In 1992, a total of
                                     1,081,163 fishing licenses were  sold
                                     in the State. In addition, 735,237
                                     Trout Stamps were sold. These sales
provided $17 million in revenue to
the Pennsylvania Fish and Boat
Commission. Over 2 million people
participated in fishing (anglers
under age 16 do not need a
license) and spent  between $750
and $800 million in direct trip and
equipment expenditures. This trans-
lates to an average of $750 to $800
per angler per year. This is a signifi-
cant contribution to the economy.
    In addition, there are 311,893
registered boats in Pennsylvania that
generated $4.2 million in fees for
the Fish and Boat Commission in
1992. An estimated 3 million Penn-
sylvanians participated in boating
activities and contributed $3.056
billion to the economy for equip-
ment, supplies, food, lodging, fuel,
etc.

Connecticut

    Entire industries are based
wholly, or in part,  on having clean
water resources. These include fish-
ing, boating, swimming, and a vari-
ety of recreation or tourism-related
industries. An extensive survey was
conducted by the University of Con-
necticut College of Agriculture and
Natural Resources for EPA Region 1.
The final report titled, The Economic
Importance of Long Island Sound's
Water Quality Dependent Activities,
released in January 1992, was based
on survey data collected between
June 29 and November 29, 1990.
    The study estimates that the
value of Long Island Sound to the
economies of New York and Con-
necticut for water-quality-dependent
activities was $5.5  billion in 1990.
Three billion dollars of this was
attributed to Connecticut's
economy. The following discussion
briefly summarizes use valuations for

Connecticut's portion of Long Island
Sound.
    Commercial finfish and shellfish
landings were estimated to be $53
million.  Specific associated industries
directly  related to harvesting
increases this value to $148.4 mil-
lion. Additional industries relating to
the processing, wholesaling, and
retailing of fish and shellfish were
not considered. Thus, the value this
industry adds to the Connecticut
economy is understated.
    An  estimated 7.5 million per-
sons visited Connecticut's beaches
in 1990. Studies conducted in
Rhode Island and Florida indicate
that this translates directly into
$159.1  million for Connecticut's
economy (on average, $21  per per-
son per year). Related contributions
to the State's tourism industry
increase this estimate to $361.45
million.
    Sportfishing constitutes another
important industry in Long Island
Sound.  Roughly 330,000 people
participated in the sport in  1991.
Direct expenditures associated with
sport fishing is estimated at $258.5
million (on average,  $780 per
angler per year). Related activities
increase this estimate to $624.6
million contributed to Connecticut's
economy (on average, $1,890 per
angler per year).
    Recreational boating represents
the largest industry that depends on
maintaining water quality. Direct
expenditures for equipment and
services were estimated at $836
million.  This increased to $1.84
billion with the inclusion of related
activities.
    Finally, an attempt was made to
estimate the value of salt marshes as
a resource  unto themselves and not
as developable land. Many  values,
such as flood control and erosion
buffers, were not assigned dollar
values. A conservative estimate of
the value of the marshes as spawn-
ing grounds and feeding areas for
commercial and recreational fishes
was calculated at $93.75 million.
This value was equally divided
between New York and Connecti-
cut.
    Connecticut's shellfish industry
has grown from a han/est of 30,000
bushels in 1972 to 900,000 bushels
in 1992 with a value exceeding $46
million. The shellfish industry
contributes approximately $500,000
in goods and in-kind services to the
Connecticut Department of Agricul-
ture, which oversees the State's
shellfish industry.
    An estimated 392,419 acres are
available for growing shellfish; of
these, over 46,500 are currently
cultivated. Eighty percent of all acre-
age available for shellfishing is cur-
rently approved or conditionally
approved. The remaining 20%
(78,009 acres) is closed. Four million
bushels of oyster shells have been
planted in an attempt to restore
State public oyster beds. Manage-
ment efforts of local shellfish com-
missions are increasing, and several
towns, including Stamford, Norwalk,
Guilford, and Madison, have begun
"relay" programs to enhance recre-
ational shellfishing.
    Other fisheries, including lob-
sters, finfish, squid, hard clams,
scallops, and conch, contribute sig-
nificantly to Connecticut's fishery
harvest. This harvest amounted to
19,200,000 pounds in 1992,  com-
bining  live weight of fish, lobsters,
and squid plus the meat of oysters,
clams,  scallops, and conch. At an
off-vessel value of nearly $60  mil-
lion, this makes  Connecticut the

                                         The stench of the Potomac
                                     River in the 1960s made recreation
                                     on or near the river undesirable.
                                     The change in the water quality
                                     today is readily discernible. Today
                                     residents and visitors recreate along
                                     its banks as well as partake in vari-
                                     ous boating activities on the river.
                                     Water sports such as rowing, wind
                                     surfing, and annual water vehicle
                                     competitions have become part of
                                     the Potomac River culture in the
                                     District. Increased development
                                     along the Georgetown and
                                     Alexandria water fronts are another
                                     symbol of the river's resurgence.
                                         There has been a return of rec-
                                     reational fishing to District waters.
                                     Surveys conducted by fisheries man-
                                     agement programs have clearly
                                     shown that fishing and the number
                                     of anglers have increased greatly.
                                     The sale of fishing licenses in the
                                     District provided the support for
                                     these surveys. The number of fish-
                                     ing licenses sold in 1993 (12,916) is
                                     more than two and one-half times
                                     the number sold in 1988 (4,900
                                     licenses)—the first year fishing
                                     licenses were sold.
                                         These benefits are real and it  is
                                     important to note that they would
                                     not have been feasible without the
                                     leadership of the Federal Govern-
                                     ment, State government, local gov-
                                     ernment, citizen groups, and indus-
                                     try all working together.

                                     lished 20 Year Trends in Water
Quality of Rivers and Streams in New
York State in 1993. The study  re-
ports trends in macroinvertebrates
from 1972  to 1992.  The increase in
macroinvertebrates such as mayflies,
caddisflies and stoneflies is a signifi-
cant indicator of the  improving
health of a  waterbody. The follow-
ing describes 10 of New York's
greatest success stories:

Canandaigua Outlet below
Canandaigua - The stream in 1972
had 3 to 4  inches of  black organic
sludge downstream of the sewage
discharge. Following  the 1980
upgrading of the Canandaigua
Sewage Treatment Plant, mayflies
and caddisflies are now found at the
downstream site.

Cattaraugus Creek, Gowanda -
Water quality is now  considered
excellent in Cattaraugus Creek; the
benthic  fauna is dominated by intol-
erant species. Moderate to severe
pollution from tannery and glue
processing discharges was well
documented in 1976. These dis-
charges have since been eliminated.

Cayadutta  Creek below
Johnstown - Severe pollution  was
well documented at all  sites down-
stream of the Gloversville-Johnstown
wastewater treatment facility.  Fol-
lowing the  1991 upgrade of the
plant, species richness indicators
increased from 8 to 23, and may-
flies, stoneflies, and caddisflies  were
found, similar to the upstream site.

Lower Hudson River below
Albany - All biological indices have
improved below Albany since  1972
and may be attributed to many
improvements in municipal and

industrial sewage treatment. Several
blue crabs were collected in this
reach in 1992.

Mohawk River below Rome -
From 1972 to 1989, species rich-
ness rose from 8 to 24 species, and
mayflies, stoneflies, and caddisflies
appeared. The change is attributed
to improved treatment of both
industrial and municipal wastes.

Mohawk River below Utica -
Following the construction and
upgrade of sewage treatment facili-
ties, the macroinvertebrate fauna
changed from a tolerant worm and
midge fauna to a diverse fauna
containing mayflies and caddisflies.

Oneida Creek below Oneida - The
1982 upgrade of the Oneida Sew-
age Treatment Plant changed the
fauna from a severely impacted
community of worms and midges
to a diverse community of mayflies,
stoneflies, and caddisflies.

Skaneateles Creek, entire length -
Most sites were found to be severely
impacted in 1972. In 1992, follow-
ing improved treatment of most
discharges, diverse communities
were found, with numerous mayflies
and caddisflies.

Tonawanda Creek below Batavia -
The former fauna below the sewage
discharge was a classic worm and
midge sewage fauna. Following the
1990 completion of the new Batavia
wastewater treatment facility, this
formerly severely impacted site now
harbors many mayflies and
caddisflies.
Upper Hudson River below Glens
Falls - Mayfly/caddisfly species
increased from 1  to 7 from 1972 to
1986, following numerous improve-
ments in treatment of municipal
and industrial wastes. Biological
changes were accompanied by
improvements in  water clarity.

Water Quality Benefits in the
Nation's Waterbodies

Iowa's Swan Lake

    In the early 1980s, Iowa's Swan
Lake suffered from turbidity,
sedimentation, nuisance algal
blooms, and frequent fishkills. By
1990 conditions had changed:*

•  In 1990, visits  to Swan Lake State
Park were up 170% from 1986
levels, and camping in the park
more than doubled during the same
period.

•  Between 1982 and 1989, the
number of anglers at the lake
increased more than sevenfold.

•  From 1987 through 1990, the
value of fishing at Swan Lake
exceeded $1.75 million.

•  Between 1986 and 1990, conces-
sion income at the park quadrupled.

•  Camping receipts in 1990 were
2.5 times higher than those of
1986.

                                       accounted for $8.4 billion per year.*

                                       Gulf of Mexico^"

                                           There are almost 2 million  regis-
                                       tered motor boats in the five Gulf
                                       States and an estimated 4 million
                                       recreational anglers. In  1991  the
                                       National Marine Fisheries Service
                                       estimated there were 15.5 million
                                       marine recreational fishing trips in
                                       the Gulf of Mexico region. Private
                                       and rental boat anglers accounted
                                       for the highest percentage of the
                                       fishing effort.
                                           The  Gulf of Mexico is especially
                                       rich in fish and shellfish species.

                                       States in terms of value in 1990:
                                       Louisiana, Texas, and Florida. Sev-
                                       enty percent of the 346 million
                                       pounds of shrimp landed in the U.S.
                                       in 1990  came from the Gulf States
                                       (250  million pounds) valued  at
                                       $420 million. Other important
                                       shellfish  include blue crabs and oys-
                                       ters. In 1989, Texas and Louisiana
                                       landed 11.7 million pounds of tuna
                                       valued at $22.5 million. The  Gulf
                                       also accounted for 11.5 million
                                       pounds of shark valued at $7.9
                                       million.
Great Lakes*

    The Great Lakes provide
tremendous economic and ecologi-
cal benefits to the area. One quarter
of all  U.S. industry and more than
70%  of U.S. and 60% of Canadian
steel mills are in the Great Lakes
Basin. Over 23  million people
depend on the Great Lakes for
drinking water. The area affords
habitat for a vast array of plant and
animal species, many of which are
native to the Great Lakes Basin.
    Recreational benefits are also
significant. Data from the mid-
1980s indicate  that recreational
boating marinas employed almost
20,000 people. Boat sales and other
boater spending (marina fees,
licenses, repairs, etc.) amounted to
almost $4 billion per year. Recre-
ational fishing adds another $3 bil-
lion to $7 billion per year.
    Water quality in the Great Lakes
has improved significantly since the
passage of the  Clean Water Act in
1972. Although discharges from
wastewater treatment plants have
increased due to population  growth
and development pressures,  levels of
dissolved oxygen have steadily
improved. Reductions in organic
material, solids, and phosphorus are
noteworthy as well. Phosphorus
loadings to Green Bay from the Fox
River  decreased by 3.6 million
pounds by 1982. Fish have returned
to some harbors from which they
had disappeared.

                                                 Chapter Nineteen  Costs and Benefits of Water Pollution Control  497
    The number of double-crested
cormorants, a water bird that all but
vanished in the Great Lakes in the
1970s, has climbed to 12,000 nest-
ing pairs. The number of bald
eagles is nearing the  highest level
ever measured in Michigan.
    Improvements in Great Lakes
water quality have had a positive
economic impact on  the recre-
ational fishing industry. Fishing
licenses purchased in the county of
Green Bay, Wisconsin, increased
from 19,000 in 1970 to 51,000 in
1989. Boat registration more than
doubled during the same period,
leading  to an increased demand for
launch ramps and other boating
facilities in the Green Bay area. The
revitalization of the fishery  resources
in  Lake Ontario has spurred the
development of the charter boat
fishing industry, boater and angler
access sites, fishing derbies, and
additional employment oppor-
tunities.
    Water quality improvements
 and increased lakeside development
 have caused people to return to the
 shore of Lake Erie to enjoy boating,
 fishing, swimming,  and other water-
 based activities. Algal blooms and
 bacteria counts in Ohio beach areas
 along Lake Erie have dropped  more
 than 90% from 1968 to 1991. As a
 result, Ohio's waterfront has seen an
 increased number of boating,  camp-
 ing, and vacation resort facilities
 being constructed.  From 1986 to
 1993, there was a 30% increase in
 the number of marinas in the  Lake
 Erie Basin. Ohio's Lake Erie tourism
 industry is now an $8.5 billion per
'year industry.
    Lakeshore cities, such  as Cleve-
 land, Ohio, have begun to restore
 their shorelines, which were consid-
 ered  "dead" 25 years ago. A new
 harbor and festival park have
 already been completed. Several
 museums are completed or are
 under construction  and an
 aquarium is planned.
