                         WATER QUALITY STANDARDS DIGEST

               Water Quality Sampling and Analytical Methods and

                       Applicable Stream Flow Provisions


     This digest was compiled in order to provide general information to
the public as well as to Federal, State, and local officials.  It quotes
those provisions of State/Federal water quality standards which relate to
water quality sampling and analytical methods techniques and which stipulate
the applicable stream flows.

     The water quality standards program is directed by the Environmental
Protection Agency, an independent regulatory agency which has responsibility
for approving State-adopted standards for interstate waters, evaluating ad-
herence to the standards, and overseeing enforcement of standards compliance.

     Standards, the first nationwide strategy for water quality management,
contain four major elements:  the use (recreation, drinking water, fish and
wildlife propagation, industrial, or agricultural) to be made of the inter-
state water; criteria to protect those uses; implementation plans (for needed
industrial-municipal waste treatment improvements, among others) and enforce-
ment plans; and an antidegradation statement to protect existing high quality
waters.

     A majority of the standards establish specific requirements regarding
analytical methods.  Some standards also expressly include sampling methods.
In a minority of standards, provisions are not regulatory but instead merely
describe the methods used by the state agency.  No provisions for sampling
and analytical methods were found in the nine states.

     The methodology provisions in many standards include authority for the
state agency to approve methods other than those set forth in the standards.
Where this authority exists, the state agency should be consulted prior to
actual sampling and analysis to determine whether distinct practices have
been established.  In particular, many state standards which were adopted
prior to publication of the thirteenth edition of Standards Methods for the
Examination of Water and Wastewater (APHA, AWWA, WPCF, 13th Ed., 1971) ex-
pressly require that sampling and analysis be conducted pursuant to methods
prescribed in the twelfth edition.  In these states, the state agency should
be consulted to ascertain'whether adherence to the methodology of the thirteenth
edition is now required.

     Finally, the Legal Support Division of the Office of Enforcement and
General Counsel, EPA, has published " A Primer on the Law, Evidence, and
Management of Federal Water Pollution Control Cases"(EPA, Washington, D.C.
20460, May 1972).Chapter VIII, "Gathering and Preserving Evidence in Water
Pollution Enforcement Actions," is enclosed as Appendix A to this summary.
It should be recalled that in testing for violations of standards, specific
methodology provisions of the applicable standards supersede any other method.

     Individual State-adopted provisions follow.

Flow (Implementation Plan  )

     In order to be able to certify the accomplishment of this enforcement
program the Commission will occupy and sample water quality at all the sampling
stations shown on the watershed maps.  The program contemplates the sampling
at each of these points at least five times per year during the types of flow
which are more critical for the assessment of the individual water quality
parameters in that particular stream.  These samples will be adjusted by com-
putations to a common denominator of flow frequency so that they will be com-
parable one to another and from year to year.  Traditionally, the Commission
has used the flow which occurs at least 85% of the time because of certain
hydrologic considerations  in Connecticut.  Once the parameters have been
established on a common flow condition, a uniform method will be developed to
interpret quality data in  terms of the percent occurrence flow to which stan-
dards should apply.

LATEST EDITION. - A publication prepared jointly by the American Public
Health Association, American Water Works Association, and the Water Pollution
Control Federaltion, accepted by Federal, State, and local authorities in
the field of water pollution control as the authority for analytical procedures
to be utilized in the examination or analysis of waters and waste waters.

     Water Quality Standards for Colorado,  Adopted May 15, 1968.

     For purposes of enforcement of these standards, sampling will be done
at a point where these standards can be evaluated.

     For purposes of enforcement of water classification standards, sampling
of the waters will be done at any point, except for areas immediately adjacent
to outfalls and except as may be noted in the text of the standards.  In such
areas, cognizance will be given to the opportunity for admixture of waste
effluents with receiving water.

     Tests or analytical procedures to determine compliance with standards
will insofar as practicable and applicable, be made in accordance with the
methods given in the latest edition of "Standard Methods For The Examination
of Water And Waste Water" published by the American Public Health Association,
or in accordance with tests or analytical procedures that have been found to
be equal or more applicable and satisfactory and accepted and approved by the
Commission.

Flow

     No specification.  The 1966 Colorado Water Pollution Control Act, as
amended (1967) requires the Water Pollution Control Commission, in adopting
standards, to consider among other things (section 8(2)(e)),"Whether a standard
that is to be applicable to discharges into flowing water should be written in
such a way that the degree of pollution tolerated or treatment required will be
dependent upon the volume of flow of the receiving water or the extent to which
the discharge is diluted therein."

     General.  3.   Reservations.

     Maintenance of stream quality criteria is dependent upon the following
conditions.

     b.  The standards proposed are based upon the ability of the Commission
         to measure and to determine compliance.  All  measurements will  be
         made at selected sampling stations.  Such stations will  be selected
         after determining "representativeness" of the sample obtained and
         the nature of the mixing at the station.

     (No further provisions regarding sampling and analytical methods require-
ments .)

 Flow

     Design of waste treatment facilities should be based on maintaining
an effluent of such character that the Water Quality Indicators meet the
specifications as state for individual receiving streams, during a low flow
period equivalent to the minimum seven (7) consecutive day low flow recur-
ring once every 10 years.

     The sampling procedure and testing methods used will  be those currently
in common usage, such as "Standard Methods" or those published by the American
Society for Testing Materials, the U.S. Bureau of Standards, or other published
methods which are considered valid and acceptable to the Director of Health.

-------
 Flow (Enforcement)

     Water quality standards will be in effect at all times.  It is recognized,
 however, that in the cases of discharges which occur beyond the reasonable
 control of man, such as flood-flows of storm water where practicable man-made
 facilities or control measures are inadequate to the situation, that situations
 will result which are not in compliance with standards.  These will not be
 excused, but neither will immediate punitive action be taken for such extreme
 cases until the Director feels that all reasonable measures have been exhausted
 to obtain voluntary action on the part of the persons or agency responsible for
 the discharge or the land or enterprise from which it arose to correct the
 situation or treat the discharge which led to the discharge of offending material

April 8, 1969.  (a)  Introduction; (3) Determination of Compliance.

     In making tests or analyses of the interstate waters of the state, sewage,
industrial wastes or other wastes to determine compliance with the standards,
samples shall be collected in such manner and place, and of such type, number
and frequency as may be considered satisfactory by the Agency from the view-
point of adequately reflecting the condition of the interstate waters, the
composition of the effluents, and the effects of the pollutants upon the specified
uses.  Reasonable allowance will be made for dilution of the effluents in
relation to the uses of the interstate waters into which they are discharged or
other interstate waters which may be affected.  The samples shall be preserved and
analysed in accordance with the procedures given in the 1965 edition of Standard
Methods for the Examination of Water and Waste Water, by the American Public Health
Association, American Water Works Association, and the Water Pollution Control
Federation, and any revisions or amendments thereto, or other methods acceptable
to the Agency.

 Flow (General Standards Applicable to all Interstate Waters.)

     (8) ... (I)f at the applicable stream flows mentioned in the sections on
specific standards of interstate water quality and purity it is evident that the
specified stream flow may be less than the effluent flow, the specific standards
may be interpreted as effluent standards for control purposes, where applicable.
The period of record for determining the specific flow for the stated recurrence
interval, where records are available, will include at least the most recent
10 years of record, including flow records obtained after establishment of flow
regulation devices, if any.  Such calculations will not be applied to lakes and
their embayments which have no comparable flow recurrence interval"!  Where <:>trearn
flow records are not available, the flows may be estimated on the basis of
available information on the watershed characteristics, precipitation, run-off
and other pertinent data. (Emphasis of the text.)

     Specific Standards of Interstate Quality and Purity:

     (2):  Fisheries and Recreation (all classes; includes warm and cold water
F & WL*and bathing):  Discharges of sewage, industrial waste or other waste
effluents shall be controlled so that the standards will be maintained at all
stream flows which are equal to or exceeded by 90 percent of the seven consecutive
daily average flows of record (the lowest weekly flow with a once in tenyear
recurrence interval)  for the critical month(sj. (Emphasis of the text.)

    The method of water sample collection, sample preservation, analysis, and
measurement to determine water quality and the accuracy of the results shall be
in accordance with the latest Edition of Standard Methods for  the Examination
of Water and Waste Water,  or  by appropriate regulations or procedures approved
by the Nebraska Water Pollution Control Council or the Federal Water Pollution
Control Administration.

Flow  (Implementation and  Enforcement)

     H.  Stream Flow Design Criteria.  The Water Quality Criteria contained in
these standards are applicable at flows equal  to or greater than the lowest
flow for seven consecutive days which can be expected to occur at a frequency
of once every ten years.   For design purposes, this flow may be determined
by any accepted statistical procedure using published stream flow data such as
Gumbel's method of logarithmic extremal probability using low mean discharge
data from the Missouri Basin  Inter-Agency Committee studies.   The drought flow
at any point along a stream may be determined by relating the drought flows at
gaging stations and their drainage to the drainage above the point of interest
on the stream.

    "Water Quality Criteria for Intermittent Waters shall  apply:"

(1)  Whenever the waste source is discharging into waters with a record of periodic
zero flows 7 consecutive days of a once in 10-vear low flow,  (2) Whenever the de-
sign flow of the waste source is greater than the design drought flow 7 con-
secutive days of a once in 10-year low flow,  (3) Whenever the  actual flow of the
receiving waters is less than the waste source discharge.

 of  coliform bacteria  in a unit volume  of water; for techniques,  see  the most
 current edition  of  Standard  Methods for the Examination of Mater  and Waste-Mater.

      Policy Guidelines  Followed  in  Establishing Standards  and to  be  Followed
 in  Evaluating Compliance.(As amended,  3/4/68.)

      It should be noted that the  standards  are  stream  standards  and  not
 effluent  standards, as  samples taken  for the regulation and enforcement of
 these  standards  are to  be collected at the  mid-point of the stream flow at
 locations  ef  sufficient distance  downstream from the point of introduction of
 a waste-water inflow  to provide for reasonable  mixing  of the stream  and the in-
 flowing water.   Where stratification  exists, other  sampling techniques  may be
 employed.   Sampling in  reservoirs and  lakes for the purposes of  the  standards
 may be at  any point in  the body of  the water, but not  closer than 250 feet from
 the point  of  introduction of a water  contaminant.   A reservoir  or lake  is
 considered to include all of the  area  flooded when  the water in  the  basin  is at
 the spillway  level.

 apply to  the  waters of  the  main  stem  of the Pecos  River  in  New Mexico regardless
 of  the magnitude of flow.  .  .  .  Special  Standards.  The  flow  in  the  Pecos River
 and the uses  of the waters  of  the  river vary considerably from one section  to
 the next.   Because  of these variations,  two sets of special standards are proposed
 to  protect  the waters of  the river for  both existing and potential future uses.  .  .

solved Solids. (Main stem, Pecos River) ... At very low flows, the concentration
of some of the chemical constituents is quite high and quite variable, but these
flows represent a relatively small part of the total water supply of the river.
Because of its hydrologic nature and because of the regulations of the flows of
the Pecos River by dams and reservoirs, the experience at many points on the
river is that either relatively high flows exist or that there is virtually no
flow in the stream.  To allow for these low flow periods, and to protect the quality
of the stream at high flows, the standards for chlorides, sulfates and total
dissolved solids have been formulated in terms of mathematical relationships
between flow and the concentration of the particular constituent.  Special
standards for this purpose apply only to samples collected at the station
indicated and for periods during which the flow in the stream is within the
range used to establish the relationship.

OREGON

     Implementation and Enforcement Plan for the Public Waters of the State
of Oregon, May, 1967.  Water Quality Standards Surveillance Plan for
Drainage Basinsin Oregon; General Surveillance.

     The present state 6'f Oregon's water quality surveillance program
involves periodic checking of fixed stations that are selected as
monitoring or control points above and below pollution  sources or near
the mouths of streams.  As these points it is usual to  run a sanitary
survey  consisting of date, time, flow, pH, temperature, dissolved oxygen
(DO), biochemical oxygen demand  (BOD), Perle Benson Index  (PBI), specific
conductance, most probable number of coliforms (MPN), and any other
parameter that appears to be pertinent to the particular area or condition.
In many cases waste treatment samples, domestic, municipal, agricultural
or industrial, are analyzed jointly with the sanitary survey to coordinate
cause and effect relationships.  In addition to the sanitary survey,
basic data are run at strategic  locations.  For these points laboratory
analysesare performed including  pH, color, turbidity, total solids,
suspended solids, alkalinity, hardness, sulfates, ammonia nitrogen, nitrate-
nitrogen, phosphates, and chlorides.  Wherever other chemicals or
problems are suspected, special  analyses are made to characterize these
conditions.  All testing is in accordance with Standard Method'**.
Frequency of sampling varies from daily to yearly depending on needs for
the data.  Each of the stations  is identified by code numbers, river mile
*Mi Hi grams per Liter.
                                  19

Ultimate Needs Study with the Water Resources Board to determine minimum flow
needs. . . .  Much more work is needed before acceptable minimal stream
flows can be set.  The main needs are for travel times and physical
characteristics of the streams to determine reoxygenation coefficients and
for tests to determine deoxygenation rates.

standards enforcement should be carried out by an intensive low flow
sampling program.  Such low flow sampling would be conducted in the criti-

meet the criteria at the critical flow conditions are to be operated at
that design efficiency at all times.  This will result in water quality ex-
ceeding the criteria most of the time.

      Specific Standards Assigned to Interstate Waters.  Stream flow and
sampling considerations.  Although not covered explicitly by the standards,
it is clearly implied that the quality requirements relate to all uses
and must apply, therefore, to all flows.  At the same time, anyone know-
ledgeable in matters of water quality control will realize that a given
set of standards can be made unachievable if the normal wide fluctuation
in stream stages is not recognized.  For this reason standards have
been related to minimum monthly-average flows in specific situations where
permits are being considered.  The complexities of stream patterns argue for
the development of more information before flows are tied precisely to
quality parameters.

      Nevertheless, as presently constituted and applied, standards require
minimum practicable treatment for any situation, including a dry stream
channel, by reason of the requirement that any effluent release from a
controlled area must meet certain bacterial and B.O.D. standards (See
following discussion under "Effluent Standards").

become effluent standards as required by lack of dilution water. . . .

VERMONT

      Implementation Plan, Vermont Water Resources Board, June, 1967.

      Surveillance

      In general, sampling and analyses are done in accordance with
Standard Methods. . .  Stream sampling is done on a "grab" sample basis except
where time and space of the pollution distribution is questionable and should
be considered.

Flow

     Implementation Plan, June 1967.  Surveillance.

     . . . Stahdards shall apply to stream conditions existing during criterical
minimum low flow periods.  On many streams the critical flow does not have the
usual frequency of occurrence that can be assigned on a hydroloqic basis, but
rather the flow is regulated by the operation of hydroelectric stations.  The
usual summer or low flow operation is released during the peak electric use
time and stored during the remainder; this becomes critical on summer week-
ends.

     On streams where regulation is not a problem,the low seven-day average
flow with a return period once in ten years will be used.

     Implementation Plan, 1968.  Water Quality Surveillance Program.

     The Division of Water Resources has bad a water quality network since
1960.  It is the plan to expand the existing network and where possible to
monitor the State waters on a continuous basis.

     The Division maintains and staffs a large well-equipped laboratory
with the latest instruments.  The laboratory applies methods of analysis
that are in the current edition of Standard Methods for the Examination
of Water and Wastewater.

     The State Water Quality Network.

     The Division of Water Resources will collect river samples at the
locations listed as stream monitoring stations.

     Sample collectors will be employed and trained to properly collect,
and bring to the central laboratory, water samples from the monitoring
stations.

     Bacterial samples (coliform) will be collected at station site in
4 oz. pre-sterilized sample bottles.  The sterilizing will be done at
the central laboratory.  Bacteria bottles will be subjected to twenty
pounds pressure, 248° F for fifteen minutes.  Coliform samples will either
be brought or bussed to the central laboratory so that not more than 24
hours time will have elapsed from collection to the beginning of the
analysis.  In addition to coliform, the Division of Water Resources will
monitor fecal streptococcus and fecal coliform at all station sites.

     Water samples for mineral and other chemical determinations will be
collected at sample location in properly clean polyethylene containers.
Samples that require the addition of preservation will be collected in
separate containers.

     Temperature will be made  in the field at station location; thermo-
meter will be Fahrenheit scale and will be checked and corrected against
a Bureau of Standards thermometer kept in the central laboratory.

     Dissolved oxygen tests will be collected and fixed in the field at
station sites.

     River Samples will be made at a point judged by samples to be repre-
sentative of stream flow.  The only exception to this criteria will be
on the Kanawha River where presently mass discharge points are located
at each bridge sample station.

 Flow (Criteria; set for individual basins.)

     The following stream quality standards are to apply at all times
when flows are equal to or greater than the minimum mean 7-consecutive
day drought with a 10-year return frequency.

govern the selection of sampling sites.

     a.  Bacteriological standards which protect water supply and full
body contact will be determined at water supply intakes and designated full
body contact recreation areas.  Bacteriological standards covering limited
body contact may be determined at any point on the stream.

     b.  Basic chemical analysis will be determined from samples taken at
established U.S.G.S. sampling points.

     c.  Parameters which are toxic or generally affect aquatic life, wild-
life, etc. will be determined at any point in the stream as indicated by
conditions.

involved in the standards, analysis will be in accord with "Standard
Methods for the Examination of Water and Wastewater, 12th Edition, 1965",
where applicable.

     Where standard methods of testing have not been established, the
suitability of testing procedures shall be determined by the public
agencies involved.
