        FOREWORD
        I  am pleased to make publicly available the Guide to Selected National
        Environmental  Statistics  in the U.S. Government.  This Guide contains
        information on  selected  sources  of environmental  statistics  from  U.S.
        government agencies. It is one of the first major outputs developed by EPA's
        new Center for Environmental Statistics in the Office of Policy, Planning and
        Evaluation.  This information improves our ability to focus resources on
        priority problems and promising solutions.

        Increasingly, statistically  valid information is  an essential  component  of
        risk-based, scientifically-sound environmental policy. Data on environmental
        problems  cannot contribute to good policy if it  is scattered across many
        agencies, if its quality is uncertain,  or if it is difficult to access.  This
        Guide is intended to help overcome these problems.  It lists and describes
        environmental  data sources  from  twenty-three  offices in  six  Federal
        departments and the  Environmental Protection Agency.   The range is
        impressive, from data on the health of forests to  surveys of hazardous and
        non-hazardous waste.  Particularly innovative is the computerized version of
        the Guide, which allows users to view excerpts of the actual data in the various
        collections.

        This Guide is an important step forward in cooperative efforts to address highly
        varied environmental responsibilities and legal mandates.

        My thanks to the managers and staff of the many agencies who worked closely
        with EPA to complete this important contribution to our base of environmental
        knowledge.

                                  INTRODUCTION

                At a  time when  management  of natural  resources  and  protection  of
            environmental quality is high on the national agenda, access to relevant environmental
            statistics is essential. Many of today's environmental policy initiatives and priorities
            are data driven; they reflect underlying facts and information on the environment.
            This  document —  the Guide to Selected Environmental  Statistics  in the U.S.
            Government (Guide)  -- responds to the need to help analysts, decision makers,
            researchers, students, and others obtain policy-relevant environmental statistics and
            publications and locate experts who are knowledgeable about the data.

                The Guide is a reference to national-level, time-series environmental statistics
            that are compiled and distributed by the U.S. government on a regular basis. It is a
            guide to statistical programs and the primary and secondary summary statistics they
            generate, not a guide to raw data or databases. As a starting point to learn more about
            various environmental statistical programs of the U.S. government, the Guide is not
            intended to supplant information that can be obtained directly from the government
            agencies. Furthermore, it is not an inclusive guide to U.S. environmental statistical
            programs, but one to selected programs  that produce frequently sought-after,
            national-level statistics.

                 This is the second edition of the Guide  and the prototype  of  an  evolving
            sourcebook that will be updated and expanded over time. The first edition, which was
            produced cooperatively by the World  Resources Institute and the  Environmental
            Protection  Agency in  1990, was based principally  on the subjects,  topics, and
            environmental statistics contained in Environmental Trends  published by the
            President's Council on Environmental Quality in 1989. While this version essentially
            updates the original guide, several records in the original guide were eliminated
            because they did  not meet  the  criteria adopted  for  this  update. For example,
            one-time-only studies and regional studies that do not represent the "national" picture
            were dropped from this issue.

                 Contents of this second edition of  the  Guide reflect the Agency's  draft
            conceptual framework for environmental statistics and indicators. Therefore the
            Guide includes references to statistical programs that characterize and/or monitor
            "the state of the natural environment," those that study underlying and proximate
            pressures on the  environment,  and  those that  assess societal impacts on the
            environment  and  environmentally-mediated impacts on society. These include:
            statistical programs on environmental quality such as ambient air and water quality
            and on natural resources such as water resources and land use; statistical programs
            on environmental  pressures such as energy, mining, agriculture,  manufacturing,
            transportation,  and other human  activities  that have direct impacts  on the
            environment; and  statistical programs on human and institutional responses to
            environmental problems such as activities  and expenditures to prevent or control
            pollution, establish parks and protected areas, protect critical ecosystems, fight forest
            fires, and manage fisheries.

-------
                  The statistical programs in the Guide are arranged by government department
              and agency. Each entry contains information about a separate statistical program (e.g.,
              program purpose, data coverage and collection methods, geographic coverage, agency
              contacts, pertinent publications, and database access options). Information in the
              records was prepared  and provided by  government agencies in response to a
              questionnaire. The Guide also contains an index of over 150 key words and phrases
              that can be used to locate desired programs.

                  In future editions, coverage of the Guide may be expanded to include regional
              and national spatial  environmental databases;  provide  more  information  on
              international, transnational, and  global environmental data;  and include additional
              references to important health, ecological, and economic impacts, including costs and
              damages. Environmental statistics gathered by private sources — non-governmental
              organizations, corporations, research institutions, and national associations — may also
              be included. If possible, future  editions will more clearly  document  the quality,
              completeness, and limitations of the data.

                  In addition to the hardcopy version, the Guide is available in an electronic version
              that can be viewed on an IBM-compatible personal computer with 640K of memory,
              DOS 3.0 or higher, and an EGA or VGA monitor. Either version of the Guide can be
              used by starting with the Table of Contents or with the Index of Key Words. Statistical
              programs are listed by agency and title in the Table  of Contents. For example, to find
              out about air quality statistics collected by EPA, use the Table  of Contents to find
              "EPA, Office of Air Quality Planning and Standards," and then "National Air Pollution
              Control Program." However, to find statistics  on carbon monoxide, search the Index
              of Key Words for carbon monoxide. Either action will lead to the appropriate program
              or programs. The User's Guide for the electronic version explains how to conduct a
              customized search on any word or group of words in the Guide.

                  Comments on the Guide and suggestions for expanding the coverage of the Guide
              in future editions are welcomed. If you would like to place an order for the electronic

SUMMARY PROGRAM DESCRIPTION:

For more than fifty years, the Economic Research
Service  (ERS) and  its predecessor agencies have
estimated acreages and maintained an inventory of the
major uses of land in the United States at intervals
coinciding with the Census of Agriculture.

DATA COVERAGE:

Estimates are made for major land  use  classes:
cropland; grassland  pasture and range; forest land;
special use; and unclassified use. Each major class is
further  classified by specified uses and some by
ownership. Land  uses  are  also   designated as
agricultural and nonagricultural.

Agricultural land uses include: cropland (cropland
harvested, cropland failure, cultivated summer fallow,
and idle cropland); grazing  lands (cropland pasture
and permanent pasture and range); grazed forest land;
and miscellaneous agricultural uses (farmsteads, farm
roads, and farm lanes).

Special land uses include:  forest land not grazed;
intensive uses  (highways  and  roads, railroads, and
airports);  and extensive uses (national parks, State
parks, wilderness areas, Federal wildlife areas, State
wildlife areas, national defense areas,  and  Federal
industrial facilities). Unclassified  other land  uses
include: urban and other special uses not inventoried
and other miscellaneous areas such as marshes, open
swamps, bare rock areas, deserts, and tundra. Data are
analyzed for trends.

COLLECTION METHODS:

Data from the Bureau of the Census, agencies of the
Department of Agriculture,  public land management
and conservation organizations, and other sources are
assembled, analyzed, and synthesized to estimate state,
regional, and national land use acreages. Barnard and
Hexem (1988) describe how the statistical series on
acreages of cropland and other land in the United
States are constructed  and used; they also identify
sources of current and historical data and information
used in constructing the series.
COLLECTION FREQUENCY:

The major uses of land are inventoried every five years
coinciding  with  years  in which the  Census  of
Agriculture is completed. The inventories generally
have been comparable in format and coverage since
1945. The series on "cropland used for crops" dates
back to 1909.

GEOGRAPHIC COVERAGE:

All 50 states.

SUMMARY PROGRAM DESCRIPTION:

For 50 years, the Soil Conservation Service (SCS) has
been conducting periodic inventories of the Nation's
soil,  water,  and  related  resources.  The  National
Resources Inventory (NRI), which is an extension and
modification of earlier inventories, provides data on
the status, condition, and trends of these resources of
nonfederal land in the United States.

DATA COVERAGE:

The many types of data collected by the NRI process
are organized  into eight  general  categories:  soil
characteristics   and   interpretations   (including
agricultural land capability);  land  cover; land use
(including  irrigated and  non-irrigated  cropland,
grazed and ungrazed  forest land,  prime  farmland,
etc.);  erosion (such as  sheet and rill,  wind,  and
ephemeral gullies); land treatment (such as irrigation,
tillage,  and  windbreaks);  conservation treatment
needs; vegetative  condi^ns  (such  as  wetlands,
rangeland  condition  and   species,  and  pasture
management);  and potential for  conversion  to
cropland.

COLLECTION METHODS:

The NRI is a multi-resource inventory based on soils
and related resource data collected at scientifically
selected random sample sites. The NRI sample design
was  developed  by the Iowa State  University
(ISU) Statistical Laboratory at Ames. It uses census
area and  point  methods  for data  collection. Data
collection involves both field investigation and remote
sensing (photo-interpretation).

COLLECTION FREQUENCY:

Data are collected on a five-year cycle. Recent surveys
were conducted in 1977,1982, and 1987.
GEOGRAPHIC COVERAGE:

The 1987 NRI data were collected from nearly 300,000
sample sites from all counties of the United States
except those in Alaska, and in Puerto Rico and the
Virgin Islands. Most of these samples were part of the
1982 NRI which had nearly 1 million sample sites. The
1987 NRI data has a high degree of reliability at the
state level and the 1982 NRI provides a high degree of
reliability at the multi-county level. Data estimates can
be made by Major  Land  Resources Areas; SCS
Administrative  Areas; Water  Resources  Council
Aggregated   Subareas;   and  other  multi-county
geographic subdivisions.

SUMMARY PROGRAM DESCRIPTION:

The Forest Pest Management  offices  have  been
collecting data on insect and disease conditions on
forest lands of all ownerships since 1952.

DATA COVERAGE:

Data are collected on federal, state, and private forest
lands in the United States. Data are analyzed for type
of insect/disease damage (e.g., pine beetle, gypsy moth,
spruce budworm, dwarf mistletoe, root diseases, etc.),
size of area affected, and dollars lost by region and
ownership. Trend data are available.

COLLECTION METHODS:

Much of the data is collected in special aerial and
ground surveys which record short-term changes in
pest activity.  The  information  supplements   tree
mortality information gathered  in  periodic forest
resource inventories done by the Forest Service.

COLLECTION FREQUENCY:

Data are collected yearly.

GEOGRAPHIC COVERAGE:

Entire United States.

Forest Inventory and Analysis
OFFICE:

U.S. Forest Service
Forest Inventory, Economics, and Recreation Research

SUMMARY PROGRAM DESCRIPTION:

The Forest Inventory and Analysis (FIA) program is
responsible  for  making  and  keeping current a
comprehensive inventory and analysis of the renewable
forest and rangeland resources of the United States.
Initial inventory efforts began in the West hi 1930 and,
by the 1960's, inventories were completed for ah1 of the
48 conterminous states and many of the important
forested states had been re-inventoried. The inventory
data and analysis provide trend information on the
extent, condition, ownership, and composition of the
nation's forests as well as information about wildlife
habitat, forage  production, and other  resource
characteristics needed for resource planning.

DATA COVERAGE:

At least 43 kinds of resource data are  collected for
sample plots during the inventory, including land use,
land ownership, forest type, stand age, stand size and
volume classes, harvest history, soils data, tree data
(species, diameter at breast height, height, cull, etc.),
other vegetation data, and non-timber data. These data
are used to make estimates of forest land area, species
composition, Umber volume,  and net annual timber
growth, removals, and mortality by forest type, state,
region, ownership, softwood and hardwood sawtimber
species, productivity class, diameter class, and other
classifications. The volume of roundwood products
harvested  by material, species  group, region,  and
product are estimated. Estimates also  are made of
areas harvested or otherwise disturbed, regenerated to
forest, or cleared for other use. Additional estimates
of recreation use, wildlife values, site  productivity,
physiographic characteristics, and other items are
made.

COLLECTION METHODS:

Data are gathered using a two-phase sampling design,
with the first phase involving the interpretation of
aerial photography and the second phase involving
ground measurements at sample  plots, each covering
one acre. Depending upon the extent to which remote
         sensing is used, ground sample intensity ranges from
         one plot per 3,000 acres to one plot per 10,000 acres.
         Methodologies are generally described in the various
         publications listed below.

         COLLECTION FREQUENCY:

         Statewide timber inventory  information has  been
         collected  continuously  for about 50 years.  In most
         regions of the United States, the third inventory cycle
         has been completed and some  areas have  been
         inventoried as many as five times. Each year, some 50
         million acres are inventoried in the conterminous
         United States.  Currently,  this  rate  of  coverage
         translates into an inventory cycle  of 12 years for the
         nation.

         GEOGRAPHIC COVERAGE:

         Entire United States and Puerto Rico.

SUMMARY PROGRAM DESCRIPTION:

The Farm and Ranch Irrigation Survey is conducted
on a  sample of the farms and ranches reporting
irrigation hi the Census of Agriculture to provide
detailed data relating to on-farm irrigation practices.

DATA COVERAGE:

The survey generates statistics on: total acres of farm
and ranch land irrigated; acres irrigated by category of
land use; acres and yield of irrigated and nonirrigated
crops; quantity of water applied; method of application
to selected crops; acres irrigated and quantity of water
used by source; acres irrigated by type  of water
distribution systems; and number of irrigation wells
and pumps.

Also  reported  are irrigation expenditures for
maintenance and repair of irrigation equipment and
facilities; purchase of energy for on-farm pumping of
irrigation water; investment hi irrigation equipment,
facilities, and land improvement; and cost of water
received from off-farm water suppliers.

Additional information is provided on the number of
irrigated farms; depth and pumping capacity of wells
used; the number of pumps and quantity of energy used
hi irrigation; application of chemicals in irrigation;
timing of irrigation; and crop yields from irrigated
farms.

COLLECTION METHODS:

The survey is a probability sample of all irrigated farms
and ranches identified hi the Census of Agriculture,
except farms hi Alaska and Hawaii, plus horticultural
speciality  and  abnormal   farms. The survey  was
conducted by questionnaire. Two types of statistical
estimation  procedures are used  to  account  for
selection of survey sample and for nonresponse to the
questionnaire.  Methodologies are  more  generally
described hi the publications listed below.
COLLECTION FREQUENCY:

Farm and Ranch Irrigation Surveys were conducted hi
1979,1984, and 1988. The next survey is scheduled for
1993. Selected irrigation data for on-farm irrigation
have been collected hi the Census of Agriculture since
1890.

 DEPARTMENT OF COMMERCE
 Annual Surveys of Government Finances and Government Employment
DEPARTMENT OF COMMERCE
Annual Surveys of Government Finances and Government Employment
OFFICE:

Bureau of the Census
Governments Division

SUMMARY PROGRAM DESCRIPTION:

These parallel surveys of state and local government
finances and employment cover all aspects of state and
local government activities and contain detailed data
for some  specific  activities  that  relate  to  the
environment.

DATA COVERAGE:

The finance survey variables include: functions and
services such as health, sanitation, environmental
services (natural resources, parks and recreation,
sewerage, and solid waste management), housing and
community development, and water utilities; character
and object items  such  as  current  operations,
construction and land and  equipment; and  revenue
items.

The employment survey variables are: employees —
full-time, part-time, and full-time equivalent; payroll;
and functions that are the  same as those described
under the finance survey.

The finance survey produces detailed data for
expenditures for both current operations and capital
outlay. The employment survey contains data for these
same functions, showing number of employees and
monthly payroll.

Both the finance and employment surveys are designed
primarily to generate data on the total activity of state
and local governments. This provides analysts with the
ability to determine the relationships among the
various functions of government — comparing, for
example,  education or  police expenditures with
sewerage outlays — or the percentage that any specific
function is of the total.

Trend data for both series are  available in national
summations that go back to the early 1950s for
employment  and  early 1900s  for  finance  data.
Individual government data for the largest units of
government (cities greater than 50,000 population,
counties greater than 100,000 population, and all the
state governments)  follow  relatively  consistent
patterns for about the past 30 years.
COLLECTION METHODS:

The sample is the same for both surveys. It is a
stratified random sample of local governments in the
United States. Units include: all state governments;
all county governments with a population of 50,000
or more; all municipalities with a  population of
25,000 or more; and other units of local government
that meet specified financial or functional criteria.
Estimates of major U.S. totals, such as total revenue
or total expenditures, are subject to a computed
sampling variability of less than  one-half of one
percent. Other  local government totals, such as
functional expenditures, are generally subject to
sampling variability of less than one percent.

COLLECTION FREQUENCY:

Surveys are conducted annually.

GEOGRAPHIC COVERAGE:

The data are aggregated to national totals and to totals
for each of the fifty states and the District of Columbia.
The surveys  also publish  data for large individual
governments such as county governments (population
greater than 100,000), municipal governments
(populations greater than 75,000), and each of the state
governments.

DATABASE(S):

Annual Survey of Government Finance

    File A is a data file for a sample of approximately
    35,000 individual units of government containing
    revenue, expenditures, debt, and assets for each
    unit. File B is a data file for U.S. and state area
    aggregations. The totals of each state area are
    divided into eight different records (state and
    local summation, state government only, local
    government  summation, county  government
    summation, municipal government summation,
    township government summation, special district
    government summation, and school  district
    summation). This file contains 416 records.

Annual Survey of Government Employment

    This is  a single data file for a. sample of
    approximately 23,000  individual units of
    government containing employment and payroll
    data  for the month of October. (Note:  The
    samples for the Annual  Finance  and Annual
    Employment  Surveys are the  same. The
    difference in the counts between Finance File A
    and the Employment File is that the former
    includes additional units in states where it was
    possible to obtain universe data annually instead
    of relying on the sample.)

SUMMARY PROGRAM DESCRIPTION:

The decennial census provides a comprehensive set of
population  statistics for the United States. Basic
demographic  characteristics are  collected  on • a
100-percent basis. Social and economic characteristics
arc collected from a large sample of all households and
persons in group quarters.

DATA COVERAGE:

The decennial census provides demographic (e.g., age,
race, sex, relationship, Hispanic origin), social (e.g.,
education,  migration,  ancestry,  language),  and
economic (e.g., occupation, industry, income, place of
work) characteristics of the population of the United
States, Puerto Rico,  the  Virgin  Islands, Guam,
American Samoa, the Northern Marianas, and Palau.
Trend data are available from previous decennial
censuses.

COLLECTION METHODS:

Basic demographic data  are collected from
100-percent of the population. Social and economic
characteristics are collected from a large sample —
approximately one-in-six in 1980 and 1990.

COLLECTION FREQUENCY:

Decennial.

GEOGRAPHIC COVERAGE:

The fifty states, the District of Columbia, and substate
areas such  as counties, county subdivisions, cities,
towns, villages, and census tracts. Also covers Puerto
Rico, the Virgin Islands, Guam, American Samoa, the
Northern Marianas, and Palau.

        PUBLICATIONS:

        The results of the Census of Population are issued in
        various forms; printed reports, computer tape files,
        CD-ROM, and microfiche. Computer tape files are
        designed to provide statistics with greater detail than
        is feasible or desirable  to provide  in printed and
        microfiche reports. Many computer tape files also are
        released on CD-ROM. Census reports are issued on a
        flow basis for several years after the decennial census
        is completed. Several publications of the 1990 census
        have been released:

        P.L. 94-171, Population Counts — In accordance with
            Public Law (P.L.) 94-171, the Census Bureau has
            provided population tabulations to all States for
            legislative reapportionment/redistricting.

        Summary Tape File (STF) 1-A - Complete count
            population and housing  data summarized  for
            states,  counties,  county  subdivisions,  places,
            census tracts, block numbering areas, and block
            groups.

        Summary Population and Housing  Characteristics

        The Census Bureau is in the process of releasing STF
        1-B U.S. Summary File, and STF 2 Census Tracts and
        soon  will begin  releasing  General  Population
        Characteristics STF 1-C. STF 3, which presents social,
        economic, and detailed housing characteristics  for
        geographic areas comparable to STF 1-A, and STF 4,
        which is the geographic counterpart to STF 2, will be
        released in 1992.

National and Subnational Population Estimates and  National and State
Population Projections
OFFICE:

Bureau of the Census
Population Division
Population Estimates and Projections Branches

SUMMARY PROGRAM DESCRIPTION:

The Population Estimates and Projections Branches
produce current estimates of the U.S. population (the
fifty states,  the District of  Columbia, the counties,
incorporated areas, Puerto Rico, and the territories)
and project the future population.

DATA COVERAGE:

Statistics include: estimates of the total, resident, and
civilian population of the United States and by state,
with components of change;  estimates of national and
state population by age, sex, race,  and/or Hispanic
origin; projections of future population by age and sex
for states and by age, sex, race, and/or Hispanic origin
for the United States; yearly estimates  of county
population; biennial  estimates  of the population of
incorporated  places  and  functional minor  civil
divisions; and estimates of populations of metropolitan
and nonmetropolitan areas; population migration by
region; population density; and population growth rate.

COLLECTION METHODS:

Estimates  of the U.S.  population are  derived  by
updating the total population including Armed Forces
overseas at the time of the last census, year by year,
through the components of  population change. State
population  totals are estimated using vital statistics,
school enrollment, internal migration  (based   on
Federal income tax data), net international migration,
and Medicare enrollment. State estimates for age and
sex are developed by a procedure that carries forward
the decennial census data for each single year of age by
state, and allows for births, deaths, and net migration.
Net migration is estimated using school enrollment to
obtain a school-age migration rate, which is then
converted to rates  for single  years of age. The
methodology to develop household estimates is based
on national trends and estimated state trends in adult
population per household, and on estimates of adult
population  for states.  For  detailed descriptions of
specific methodologies, see reports  referenced hi
Publications.
        COLLECTION FREQUENCY:

        Data are updated annually.

        GEOGRAPHIC COVERAGE:

        Entire United States.

 Survey of Pollution Abatement Costs and Expenditures
DEPARTMENT OF COMMERCE
Survey of Pollution Abatement Costs and  Expenditures
OFFICE:

Bureau of the Census
Industry Division
Special Surveys Branch

SUMMARY PROGRAM DESCRIPTION:

The survey collects information on annual operating
costs and capital expenditures for pollution abatement
activities in manufacturing industries. The survey was
started in 1973  and has been conducted annually
except for 1987. The survey provides estimates of
pollution abatement spending for detailed levels of
industrial classification.

DATA COVERAGE:

Estimates of pollution abatement operating costs and
capital expenditures  are made for manufacturing
plants with 20 employees or more (except the apparel
group). Detailed estimates are provided by pollution
type and  for  the  following three-digit  standard
industrial  classification (SIC) industries: food and
kindred products; tobacco manufacturers; textile mill
products; lumber and wood products; furniture and
fixtures; paper  and  allied  products; printing and
publishing; chemicals and allied products; petroleum
and coal products; rubber and miscellaneous plastics
products; leather and leather products;  stone, clay,
and  glass products; primary  metal  industries;
fabricated metal products; machinery, except
electrical; electric  and electronic equipment;
transportation equipment; instruments and related
products; and miscellaneous manufacturing
industries. Detail is also provided for expenditures by
sector, for industries by four-digit SIC codes, and for
States by two-digit SIC codes. Capital expenditures
are provided for air and water pollution abatement by
abatement  technique (changes-in-production
processes and end-of-line techniques), for air
pollution abatement by type of pollution abated, and
for hazardous and  nonhazardous solid  waste
management. Operating costs  include  labor,
depreciation, materials and supplies, services,
equipment leasing, and other costs. Costs recovered
by  manufacturing  plants  from  their pollution
abatement activities are also given.
        COLLECTION METHODS:

        The probability sample  includes  about 20,000
        manufacturing plants. The sample is selected as a
        subsample of the Annual Survey of  Manufacturers
        which represents about 360,000 plants in the country.
        The probability of selection is based on the plant size
        in terms of total value of shipments. Response to the
        survey is about ninety percent.

        COLLECTION FREQUENCY:

        Except for 1987, when no survey was conducted, data
        have been collected annually since 1973.

        GEOGRAPHIC COVERAGE:

        The sample is selected to represent the entire United
        States. Estimates are given also for states and regions,
        but with less detail.

Classified Shellfishing Waters
OFFICE:

National Oceanic and Atmospheric Administration

Office of OceanResource Conservation and Assessment
Strategic Environmental Assessment Division

SUMMARY PROGRAM DESCRIPTION:

Classified  shellfishing  waters are  monitored- as  an
indicator of bacterial water quality nationwide. Waters
are classified for the commercial harvest of oysters, clams,
and mussels based on the presence of actual or potential
pollution sources and coliform bacteria levels in surface
waters. Each  shellfish-producing state classifies its
waters in accordance with guidelines established by
the National Shellfish Sanitation Program.

DATA COVERAGE:

Approximately 2,000  classified shellfishing  areas are
defined by name, location (nautical chart number, estuary,
state,  region),  classification  (approved,  prohibited,
conditionally approved, or restricted), size, and pollution
sources (identified for all non-approved areas).

Trends in classification by region from 1966  to 1990
and by selected estuaries in the northeast, southeast,
Gulf of Mexico, and Pacific from 1971 to 1990 are
available.  Areas that were reclassified because of
improved  or   diminished   water   quality  are
distinguished  from those that were reclassified as a
result of improved monitoring.

Data  also are collected on  administration of state
programs, including: identification of state agencies
responsible   for   monitoring  waters,  assigning
classification, analyzing water samples, etc.; number of
personnel; budgets;  number of  sampling  stations;
frequency of sampling; and  other factors that may
influence classification.

COLLECTION METHODS:

Data are collected by questionnaire and followed by
interviews. Classifications are noted on 265 Nautical
Charts (NOS 1:80,000).

COLLECTION FREQUENCY:

Data were compiled in 1966, 1971, 1974, 1980, 1985,
and 1990. The next survey is scheduled for 1995.

OFFICE:

National Oceanic and Atmospheric Administration
National Marine Fisheries Service
Office of Research and Environmental Information
Fishery Statistics Division, F/RE1

SUMMARY PROGRAM DESCRIPTION:

The Fishery Statistics Division develops and maintains
a national collection of statistics (biological, economic,
and sociological)  on  domestic commercial and
recreational fisheries, as well as joint ventures and
foreign catch in the U.S. Exclusive Economic Zone
(EEZ).  It maintains data files  on the processing,
freezing, and holding of fishery products, and monthly
information  on  imports  and  exports of  fishery
products. The Division also aids in developing policies
and operational  guidelines for  the  coordinated
collection and publication of basic fishery statistics. It
develops, implements,  and manages computerized
data systems  for handling, archiving, and retrieving
statistical databases.

DATA COVERAGE:

The following data are collected: monthly and annual
commercial landings (catch) in pounds and value by
species, state, county, year, waterbody, and distance
from shore; annual operating units  and number of
vessels and •fishermen  by  state, year,  and  country;
annual processed products data by state, county, plant,
species, and type of processing; annual world catch by
species, country, and area; weekly shrimp imports by
country and count  size;  and  recreational  finfish
saltwater catch by species and geographic area.

COLLECTION METHODS:

Commercial data are obtained through census of first
buyers  of  seafood, review of  logbooks, intercept
surveys, and reporting by observers. Recreational data
are collected  through  extensive   telephone  and
intercept surveys designed as a stratified random
sample. Approximately 44,000 households in coastal
counties are contacted for the telephone survey.
On-site interviews are  conducted with as  many as
56,000 marine recreational anglers for an intercept
survey.
COLLECTION FREQUENCY:

Data are collected daily, monthly, and/or yearly
depending on subject and area covered.

GEOGRAPHIC COVERAGE:

All commercial catch by U.S. flag-vessels landed hi the
continental United States, Puerto Rico,  and other
ports outside the fifty states. Recreational information
covers only marine waters.

SUMMARY PROGRAM DESCRIPTION:

The National Climatic Data Center (NCDC) collects,
processes, and archives meteorological and
climatological data from a global network of stations.
Records begin in the mid-19th century and continue to
the present.

DATA COVERAGE:

Climatic variables (e.g., temperature, precipitation,
solar  radiation,  storms,  wind,  and floods)  are
summarized for both  short-term  and  long-term
periods of record.  Data are available in published
form, on microfiche, or on magnetic tape. Derived
values relating to growing season and heating and
cooling degree days are  also  produced.  Special
statistical summaries of  actual and derived values of
meteorological elements over the world's oceans as
well as summaries used hi the study of air pollution are
available.

COLLECTION METHODS:

For about four decades, NCDC  has been receiving
climatic data from across the United States and around
the globe. Principal sources in the United States are
the National Weather Service (NWS),  the  Federal
Aviation Administration, the U.S. Air Force, the U.S.
Navy,  and the  U.S.  Coast Guard. The  NWS's
Cooperative Station Network is comprised mainly of
10,000 volunteer observers and has been recording
daily records since the 1800's. As aircraft began to fill
the skies, information on the upper atmosphere was
needed. Balloon-borne  instruments  radioed  data;
radars began to probe the clouds; rockets reached the
fringes of the atmosphere; weather satellites, both
geo-stationary and polar orbiting, now continuously
watch  and  record  the  weather.  Technical
advancements led NCDC to archive some of their data
on CD-ROM's so that  users could look at a large
amount of climatic data at one tune. The NCDC plans
to archive new datasets using the latest technical
advances  available,  such as  AS OS, Profiler,
NEXRAD, and STORM.
COLLECTION FREQUENCY:

Observations are taken at varying intervals, from every
fifteen minutes to once per month. Collections are
daily or monthly depending on type and source of
information.

GEOGRAPHIC COVERAGE:

Global land and sea, but coverage is primarily U.S. and
dependencies, especially for summarized data.

SUMMARY PROGRAM DESCRIPTION:

The National Coastal Pollutant Discharge Inventory
(NCPDI) Program is a series of database development
and analytical activities within the National Oceanic
•and Atmospheric Administration's  Strategic
Assessment Program of coastal and estuarine areas.
The cornerstone of the program is a comprehensive
database and computational framework that has been
developed  over the last nine years. The  database
contains pollutant  loading estimates  for all major
categories  of point, nonpoint, and  riverine sources
located in coastal counties or the 200-mile Exclusive
Economic  Zone that discharge to the  estuarine,
coastal, and oceanic waters of the  contiguous U.S.
(excluding the Great Lakes).

DATA COVERAGE:

The pollutant discharge estimates in the NCPDI are
made for the following base years for each coastal
component: East Coast -1982; West Coast -1984; and
Gulf Coast -1987. The estimates can be considered to
approximate pollutant discharge conditions for a five-
year period around the base year. Estimates are made
for nine major source categories and  17 pollutants.
Source categories include:  point  sources; urban
nonpoint   sources;  nonurban   nonpoint  sources;
irrigation return flow; oil and gas operations; marine
transportation operations;  accidental spills;  and
dredging operations. Pollutant  parameters include:
flow (wastewater flow or  surface runoff);
oxygen-demanding  materials   (BOD);  particulate
matter; nutrients  (total  nitrogen and phosphorus);
metals (arsenic, cadmium,  chromium, copper, iron,
lead, mercury, and zinc); petroleum hydrocarbons (oil
and grease);  pesticides (35 compounds); pathogens
(fecal coliform bacteria); and wastewater treatment
sludges. The pollutant estimates can be aggregated by
county, USGS hydrologic cataloging unit, or estuarine
watershed.
COLLECTION METHODS:

Estimates are based on a combination of computed
methodologies and actual monitored observations. For
detailed descriptions of the methodologies, the reader
is  directed  to  the various  reports  listed  under
Publications.

COLLECTION FREQUENCY:

Estimates are seasonal (winter, spring, summer, and
fall) for a base year. Updated discharge estimates for
1987 for the coastal areas of the Gulf of Mexico and for
1989 for the East Coast are being prepared.

GEOGRAPHIC COVERAGE:

Coastal areas of  the continental  United States,
excluding the Great Lakes.

SUMMARY PROGRAM DESCRIPTION:

Beginning in  1984, NOAA  undertook  the task of
providing information on the status and  trends of
environmental quality in estuarine and coastal areas.
The program  defines the geographic distribution of
contaminant  concentrations in  tissues of  marine
organisms and in sediments.

DATA COVERAGE:

Status and trends data are available from the Mussel
Watch  and Benthic Surveillance  for  four  major
elements,  twelve  trace  elements,  DDT  and  its
metabolites, selected chlorinated pesticides, selected
PCB  congeners,  approximately twenty-two
polyaromatic  hydrocarbons,  and  ancillary sediment
and tissue parameters.

COLLECTION METHODS:

Samples have  been collected since 1984 at about fifty
Benthic Surveillance sites and since 1986 at about
150 Mussel Watch sites. Sediment samples are
collected at all sites. At Benthic Surveillance sites,
benthic fishes are collected and their livers excised
and stored for subsequent chemical analysis. At
Mussel Watch sites, bivalve mollusks are collected
for analysis.

COLLECTION FREQUENCY:

Data are collected annually.

GEOGRAPHIC COVERAGE:

National coverage of all coasts including Alaska and
Hawaii.

SUMMARY PROGRAM DESCRIPTION:

The  Month  and State  Current  Emissions Trends
(MSCET) program provides emissions estimates for
nitrogen  oxides,  sulfur  dioxide, and  nonmethane
volatile organic compounds. The data set can be
used to monitor regional and/or seasonal emissions
trends or trends for specific emission source groups.

DATA COVERAGE:

National and sectoral emissions estimates for nitrogen
oxides,  sulfur  dioxide,   and nonmethane volatile
organic compounds are generated for all states in the
contiguous United States.  The  database contains
emissions data estimated by month and state for 68
emission source  groups.   Six  general  emission
categories are:  electric  utilities, industrial  fuel
combustion, commercial/residential fuel combustion,
industrial processes, transportation, and miscellaneous.
The database has been updated to include the National
Acid Precipitation Assessment Program's  emissions
inventory.

COLLECTION METHODS:

Emissions are estimated from fuel consumption and
economic activity data. The fuel consumption data are
taken  from  Department of Energy  and Energy
Information Administration data tapes and reports.
Economic activity  data are taken  from various
economic statistics reports, most  frequently the
Bureau of Economic Analysis publication  Survey of
Current  Business.  A detailed  description  of the
methodology is presented in Kohout et.al., 1990.

COLLECTION FREQUENCY:

Monthly fuel consumption and economic activity data
are collected  annually,  and preliminary  data are
updated  as  they become available. Emissions are
estimated twice: a preliminary "flash" estimate early in
the following calendar year, and a final estimate about
six months later.
GEOGRAPHIC COVERAGE:

Forty-eight contiguous states and Washington, D.C.

Department of Energy's independent statistical and
analytical agency, with a mandate to collect and publish
data and prepare analyses on energy production,
consumption, prices, and resources, and projections of
energy supply and demand.

DATA COVERAGE:

EIA collects and disseminates data on energy sources;
reserves; total production; consumption by source, by
end use sector, per capita, and per GNP dollar; energy
imports  and exports;  and related  economic and
statistical information,  both historical and forecasted
(e.g.,  energy efficiency indicators).  Trends  in  the
production of specific fuel types (e.g., coal,oil, natural
gas, nuclear, hydroelectric  power, and certain
renewable energy  sources)  and production  of
electricity by source are available.

COLLECTION METHODS:

The methods for generating energy statistics, which are
varied, are described in Appendix E. of the Annual
Energy Review. They include survey reporting by
energy production,  transmission, and distribution
companies and end  users, and calculations and
estimations made by EIA.

SUMMARY PROGRAM DESCRIPTION:

The objective of the Carbon Dioxide Information
Analysis Center (CDIAC) is to compile, evaluate, and
distribute information related to carbon dioxide (CO2)
in support  of the Department of Energy's  Carbon
Dioxide Research Program (CDRP). To accomplish
this objective, CDIAC identifies researchers' needs for
data, models, and information; obtains, evaluates, and
ensures the quality of the information; and works with
other national and international data centers as well as
with individual researchers to promote and facilitate
the exchange of data. CDIAC supports the data and
information needs of researchers studying the effects
of increasing atmospheric CO2 on climate, carbon
cycle processes, and resources.

DATA COVERAGE:

Variables   measured  and   analyzed  include  any
COa-related or  greenhouse gas-related parameter.
Trend data include:  atmospheric CO2 and methane
concentrations from surface monitoring sites and
from ice cores; CO2 emissions resulting from fossil
fuel consumption and cement production; historical
land  use  data   in Southeast  Asia;  long-term
temperature and precipitation,  cloudiness,  and
sunshine records for the United States; global and
hemispheric temperature anomalies; dust veil indices;
umbral/penumbral ratios; and radiocarbon data from
oceanographic cruises.

COLLECTION METHODS:

Data sets that are archived and distributed by CDIAC
have either been sent to CDIAC voluntarily by the
collecting agency or researcher or have been sent to
CDIAC as  a result  of contracts made by CDIAC.
CDIAC identifies data sets critical to greenhouse and
global  warming  issues by  conducting  surveys of
researchers and users of CDIAC's data products;
contacting researchers and agencies addressing global
warming issues; attending scientific conferences and
symposia;  and soliciting  suggestions  from DOE
managers. CDIAC does not impose format restrictions
on  individuals  and  agencies that  archive data at
CDIAC. CDIAC  accepts the data in whatever form
(i.e., hardcopy, dBASE files, LOTUS files, flat ASCII
files)  is  most  convenient  for  the  contributor.
Irrespective of the source, CDIAC reviews all data
sent to CDIAC before documenting and distributing
the data set. These reviews, which  are often
extensive, involve consultation with the contributing
agency or researcher. CDIAC does not correct or
distribute any data sets or computer models without
the written consent of the contributing individual or
agency.

COLLECTION FREQUENCY:

The frequency of data collection with the CDRP
program ranges from hourly (e.g., atmospheric CO2
concentrations) to decennial (e.g., land use changes in
Southeast Asia).

GEOGRAPHIC COVERAGE:

Global.

Division of Health Examination Statistics

SUMMARY PROGRAM DESCRIPTION:

The National Health Survey Act of 1956 provided for
the establishment and  continuation  of  a National
Health Survey to obtain information about the health
status of the population in the United States. The
National Center for Health Statistics is responsible for
this  program. During  the  1960s  three  Health
Examination Surveys (HES Cycle I, II, and III) were
conducted  on  probability samples of the  civilian,
non-institutionalized population of the United States.
A nutritional component was included in subsequent
health examination surveys: the first National Health
and  Nutrition  Examination Survey  (NHANES  I)
conducted during 1971-75, NHANES II conducted
during 1976-80, the Hispanic Health and Nutrition
Examination Survey (HHANES)  conducted during
1982-84,  and  the  ongoing  NHANES  III.
Environmental data collection effort  mainly started
with NHANES I.

DATA COVERAGE:

NHANES I:

     Data  collected  include: general physical
     examination, nutrition examination, carbon
     monoxide tests, and tobacco use.

NHANES II:

     In addition  to the variables listed above, the
     following  data  were  collected:  lead  and
     carboxyhemoglobin hi  whole blood;  organo-
     chlorine pesticides, residues, and metabolites
     in urine  specimens  (2,4,6-trichlorophenol;
     2,5>6-trichloro-2-pyridinol;  2,4,5-trichIorophenol;
     pcntachlorophenol; para-nitrophenol;  2,4,5-T;
     2,4,-D; silvex; dicamba; alpha-monocarboxylic
     acid; dicarboxylic acid);  and  organochlorine
     pesticides, residues, and metabolites in serum
     (trans-nonachlor; heptachlor  epoxide;  oxy-
     chlordane; heptachlor; alpha-BHC;  beta-BHC;
     gamma-BHC;  delta-BHC; aldrin;  endrin;
     dieldrin; DDT; DDE; DDD; hexachlorobenzene;
     and mirex). Also analyzed were: heating fuel
             used; tobacco use; and pesticide and disinfectant
             exposure and poisoning.

        HHANES:

             Data comparable to the NHANES II study were
             collected from the Hispanic population.

        NHANES III:

             In addition to variables listed above, the following
             data are collected: occupation and  protective
             equipment and exposure to volatile substances;
             source of drinking water; cadmium and cotinine
             in urine. Also the following pesticides in urine are
             measured: pentachlorophenol; 2,4-dichlorophenol;
             2,5-dichlorophenol; 1,4,5-trichlorophenol;
             2,4,6-trichlorophenol;  4-nitrophenol;
             3,4,5-trichloro-2-pyridinol; 1-naphthol; 2-naphthol;
             isopropoxyphenol;  carbofuranphenol; and
             2,4-dichlorophenoxacetic acid. Blood from the
             Priority Toxicant  Reference  Range Study is
             analyzed for:  benzene; toluene; ethylbenzene;
             xylenes;  styrene;  trimethylebenzenes; carbon
             tetrachloride;   chloroform;   dichloromethane;
             trichloro methane;  trichloroethylene;
             tetrachloroethylene; and dichlorobenzenes.

        COLLECTION METHODS:

        The Health and Nutrition Examination Surveys are
        complex, multi-stage, stratified,  probability sample
        surveys. The process of selecting a sample  of persons
        to be  examined involves the  selection of primary
        sampling units,  census enumeration.districts,
        segments, households, eligible persons, and finally
        sample persons. The pesticides and volatiles are being
        measured on a volunteer subgroup only. Data are
        collected  by direct  physical  examinations,  tests,
        measurements, and interviews.

        COLLECTION FREQUENCY:

        Periodic (as determined appropriate).

        GEOGRAPHIC COVERAGE:

        Entire United States.

DATA COVERAGE:

The Range Site Inventory produces data and maps on
habitat types which can be interpreted, along with
other data,  as to their production  capabilities and
suitability for grazing, wildlife, recreation, natural
beauty, watershed management, and open space.  A
Range  or  ecological  site  map provides the basic
ecological data for planning the use,  development,
rehabilitation, and management of rangeland. To date,
data on approximately 89,648,000 acres have been
compiled. Additional inventories are being conducted
annually. Data are also used to evaluate the potential
of range ecosystems to produce and sustain distinctive
lands and amounts of vegetation.

COLLECTION METHODS:

Data are collected by double sampling range sites
(harvesting and estimating) and soil survey.

COLLECTION FREQUENCY:

Every ten years.

GEOGRAPHIC COVERAGE:

All inventories completed  to date are within the

 SUMMARY PROGRAM DESCRIPTION:

 This program maintains a database on all Bureau of
 Land Management (BLM) timber sales. It produces
 detailed information on  every timber  sale' offered
 and/or sold and is capable of generating reports to
 give current  status  of individual timber sales or
 summaries  of particular information  for  any
 administrative unit from the resource area level up
 to the bureau level.

 DATA COVERAGE:

 Data include information on each cutting unit (e.g.,
 acreage, volume, value, and species of timber, uncut
 volume and acreage,  and unhauled volume and
 acreage). For each timber sale, the database has the
 following information: appraised value;  total
 purchase price; sale date; approval date; expiration
 date; purchaser; total volume and value by species;
 unpaid balance; contract modifications;  and
 termination date.

 COLLECTION METHODS:

 The information on cutting unit acreage and volume
 and appraised sale value is generated when the sale is
 advertised. The information on total purchase price,
 value of cutting units, sale date, purchaser,  and total
 purchase price is generated when the sale is made.
 Information on cutting and payment is generated
 monthly, and contract modifications and termination
 data arc generated as they occur.

 COLLECTION FREQUENCY:

covers fifty-six  National Park  Service units. The
program provides basic information on  visibility
conditions in National  Park  Service  Class I areas
throughout the  country, primarily in the western
United States. Information is used to assess trends,
develop source-receptor relationships, and identify
cause-effect relationships.

DATA COVERAGE:

Principal components measured by optical monitoring
are: view (scenic vistas),  atmospheric extinction
coefficient, and Beta scattering. Principal components
measured by fine particle sampling are: PM-10, fine
mass,  nitrates, sulfates, organic carbon, elemental
carbon, elements (Na-Pb),  optical absorption,  and
atmospheric levels of hydrogen, carbon, nitrogen, and
oxygen.

DEPARTMENT OF THE INTERIOR

National Recreational Trails,  Long-Distance Trail Management, and
National Trail Inventory and Plan
OFFICE:

National Park Service
National Trails System Branch

SUMMARY PROGRAM DESCRIPTION:

National Recreational Trails are defined within the
National Trails System Act. Since 1968, over 780 trails
have been recognized  by either the Secretary of
Interior or the Secretary of Agriculture. Although the
majority are on Federal lands, the trails are found in all
states and reflect a broad diversity of trails cherished
by Americans. The National Park Service (NPS)
expedites   certification   and  re-certification,  and
maintains files on all registered trails.

Long-Distance Trail Management seeks to implement
the National Trails System Act by promoting and
enhancing the nation's 17 national scenic and national
historic trails. Management responsibilities include
funding and staffing, monitoring trail conditions,
protecting trail corridors, providing public and press
information, and fostering certification, interpretation,
public involvement, and interagency coordination.

The National Trail Inventory and Plan program seeks
to implement the requirement hi the National Trails
System Act for a National Trail Plan. To provide a
foundation for the Plan, a national inventory is being
conducted and regional directories of trail resources
are being published. The program works with regional
trails interest groups to identify new trail opportunities
and strategies to protect the region's system  of trails,
and assists individual states and metropolitan areas hi
developing  trails,  recreational  greenways,  and
corridors.

DATA COVERAGE:

For National Recreational Trails,  data for each trail
include: state(s) where trail is located; trail name and
registration number; seasons and types of use; types of
surface; trail length; date designated; and address of
administering agency.

For Long-Distance Trails, statistics  vary widely, but
generally include: numbers of trails by type; length of
route, completed route, adjacent motor route, or high
potential route  segments;  contacts  for  agency  and
citizen volunteer groups associated with each trail;
dates of Congressional establishment and planning
steps; and general budgets and expenses for each
NFS-administered trail for Fiscal Years 1989-1991.
More detailed information, such as trail condition or
ownership by State, may not be known or may only be
available from field offices.

Under the National Trail Inventory and Plan, primary
data elements include: trail or area name; managing
agency and type; area acreage; total number and
mileage of trails in the management area; designated
trail use mileage;  and information  on associated
activities and services, access, and contacts.

COLLECTION METHODS:

Data are collected through inventory, research in field
offices, surveys using standardized forms, inspection of
planning documents, and analysis of  application
submissions.

COLLECTION FREQUENCY:

Data for National Recreational Trails are collected once,
upon application. Collection frequency for Long-Distance
Trails varies as needed. For the National Trail Inventory
and Plan, nine NPS Regions will be inventoried between
1987 and 1995 and re-inventoried every 5 years as funding
and staffing allow.

GEOGRAPHIC COVERAGE:

Entire United States.

SUMMARY PROGRAM DESCRIPTION:

The National Containment Biomonitoring Program
(NCBP) is maintained by the Fish and Wildlife Sendee
(FWS) to document temporal and geographic trends
in concentrations of persistent environmental
contaminants that may threaten fish and wildlife. The
NCBP is the FWS segment of the National Pesticide
Monitoring Program, a multi-agency monitoring effort
by the member agencies of the Federal Committee on
Pest  Control.  Since  1965,  FWS has  periodically
determined  concentrations of   potentially  toxic
elements and selected organochlorine chemicals in fish
and wildlife collected from a nationwide network of
stations.

DATA COVERAGE:

Organochlorine  chemical  residues  measured  in
freshwater fish, starlings, and waterfowl samples and
analyzed for trends  include: p,p'-DDT  and
DDT-metabolites p,p-DDE  and p,p'-DDD (TDE);
PCBs (aroclor 1242,1248,1254,1260); aldrin, dieldrin,
cndrin; heptachlor; heptachlor epoxide; chlordane
(five  isomers);  toxaphene;  benzene hexachloride;
lindane; hexachlorobenzene; methoxychlor; mirex;
pentachloranisole;  and dacthal. In addition,
freshwater fish are  analyzed for  elemental
contaminants, including: arsenic; cadmium; copper;
lead; mercury; selenium; and zinc.

collected in replicate from 112 stations in major rivers
throughout the United States and hi the Great Lakes.
Preferred fish species, methods of collecting, shipping,
archiving, and preparing samples, and data analysis
procedures are described in Ribick et al., 1983; Lowe
ct  al., 1985; Schmidtt et al., 1990; Schmidtt and
Brumbaugh, 1990 (See Publications). Quality control
samples are analyzed to estimate accuracy and
precision of results.
Starlings are collected in replicate from 139 terrestrial
sites in the  contiguous  48 states.  Chemical and
statistical methodologies are described in Bunck et al.,
1987.

Wings of mallards and black ducks shot by hunters hi
the continental United States are  collected to assess
body  burden  of  organochlorine  compounds  in
migratory birds. Procedures for collecting, pooling,
sample preparation, chemical analysis, and statistical
analysis are described in Cam, 1981 and Prouty and
Bunck, 1986.

COLLECTION FREQUENCY:

This monitoring program has continued at two- to
four-year intervals since  1965.  The  FWS  is in  the
process of reviewing the NCBP and an agency initiative
has been approved for FY1992.

GEOGRAPHIC COVERAGE:

The fish monitoring network covers the major rivers of
the United States and the Great Lakes. Starling
collection sites are located within each five-degree
block of latitude and longitude in the contiguous 48
states.  Mallards  are   collected throughout  the
continental United States and black duck are collected
from the Atlantic Flyway.

National Survey of Fishing,  Hunting, and Wildlife-Associated Recreation
OFFICE:

U.S. Fish and Wildlife Service
Federal Aid Division

SUMMARY PROGRAM DESCRIPTION:

The National Survey  of Fishing, Hunting,  and
Wildlife-Associated Recreation has been conducted
every five years since 1955. It represents one of the
oldest and most comprehensive ntinuing recreation
surveys.

The purpose of the survey is to gather information on
the number of anglers,  hunters, and nonconsumptive
•wildlife recreation participants in the United States, as
well as how often they participate  and how much
money they spend on these activities. Nonconsumptive
rccreationists are those  who enjoy photographing,
observing, and feeding wildlife.

DATA COVERAGE:

Numerical data include:  number of participants in
different  types of hunting, fishing,  and
wildlife-associated  recreation   activities;  days of
participation and trips; species hunted and fished;
types of expenditures; and selected socioeconomic
characteristics of participants.

COLLECTION METHODS:

The 1985 survey was conducted hi two phases. In the
first phase, a sample of almost 110,000 households
nationwide was screened, mostly by telephone, to
determine who in the household had participated in
wildlife activities. The second phase of the  survey
consisted of detailed in-person interviews conducted
with  subsamples  of  anglers, hunters,  and
non-consumptive participants who were identified in
the screening phase. Sample sizes were designed to
provide statistically reliable results at the state level for
the surveyed activities. In 1985, a total of 33,973 anglers
and hunters and 30,177 non-consumptive users were in
the detailed sample.

Some changes have been made in the 1991  survey
design. For  example,  telephone  interviews  were
conducted three times during the year (as opposed to
once) and interviewees were asked to recall hunting,
fishing, and  non-consumptive  activities  for  the
previous four months (as opposed to one-year recall).
Despite these changes,  data from the 1991 survey will
be comparable with previous survey results.
        COLLECTION FREQUENCY:

        Five year intervals (except between the 1985 and 1991
        surveys because additional tune was required to revise
        survey design).

        GEOGRAPHIC COVERAGE:

        The entire United States.

Fish and Wildlife Enhancement
Branch of Special Projects

SUMMARY PROGRAM DESCRIPTION:

In 1975, the U.S. Fish and Wildlife Service established
the National Wetlands Inventory (NWI) to develop
technically sound and comprehensive information on
the characteristics and extent of wetland resources in
the United States.

DATA COVERAGE:

Status and trends information is available for selected
wetland types including: estuarine wetlands; palustrine
wetlands; lacustrine wetlands; and deepwater habitats
in the lower forty-eight states. In addition, statistical
data are available for coastal waters and bay bottoms,
coastal marshlands and mangroves, recent changes in
inland vegetated wetlands, recent changes hi lacustrine
deepwater  habitats,  estimates  of  current  annual
wetland losses, estimates of wetland losses by flyways,
states with significant changes in wetland resources,
indicators of  development pressures on  wetland
resources,  and  causes  of wetland  losses.  The
Emergency Wetlands Resources Act of 1986 requires
that updates  of  the wetland  status  and trends  be
produced on a 10 year cycle with reports due hi 1990,
2000,2010, etc.

COLLECTION METHODS:

A stratified random sample is used with the basic data
strata being formed by state boundaries and the 35
physical subdivisions described by E.H.  Hammond
0.970).  Additional strata specific to the study are
special  coastal  strata   encompassing the Marine
Intertidal category, the Estuarine System, and  other
strata encompassing the Great lakes. This results in
over 200 strata for the study. Sample units are allocated
to strata in proportion  to the expected  amount of
wetland and deepwater habitat acreage as estimated
by earlier work. Each sample unit is a four-square-mile
area,  two miles  on each side. After the units are
selected at random within strata and  plotted on U.S.
Geological   Survey   topographic   maps,   aerial
photography is obtained  for the new time period. All
wetland and deepwater habitat changes are marked as
to  cause,  either natural or human induced. The
photointerpreted data for each unit is then prepared
        for computer analysis. Several quality control checks
        are routinely made to eliminate errors.

        COLLECTION FREQUENCY:

        Data are  collected continuously with updates on a
        ten-year cycle. The 1990 update provides trend data on
        wetlands losses and gains between the 1970's and the
        1980's.

        GEOGRAPHIC COVERAGE:

        The wetland  mapping  phase of the  project has
        produced map coverage for  approximately seventy
        percent of the lower forty-eight states, twenty-two
        percent of Alaska, and all of Hawaii, Puerto Rico, and
        Guam.  Wetland  status  and  trends information  is
        designed to provide statistical estimates on a national
        basis (lower forty-eight states). In addition, regional
        intensification studies are available for the Chesapeake
        Bay Region (Delaware, Maryland, Pennsylvania, West
        Virginia, and  Virginia), and  the Central  Valley of
        California. Other statewide  status  information  is
        available for  the  states  of Florida, Delaware, New
        Jersey,   Illinois,   Washington,   Maryland,   and
        Connecticut.  Status  reports  covering  the coastal
        wetlands of Alaska and the Prairie Pothole Region
        (North  Dakota, South Dakota, Minnesota) are also
        available.

Waterfowl Breeding Population and Habitat Survey
OFFICE:

U.S. Fish and Wildlife Service
Office of Migratory Bird Management

SUMMARY PROGRAM DESCRIPTION:

This survey is designed to provide annual breeding
population estimates and measure breeding habitat
changes over a major portion of the duck breeding
range in North America.

DATA COVERAGE:

Variables measured include  number of breeding
waterfowl by species (for example, northern pintail and
mallard, Canada goose, canvasback and redhead, and
Tundra swan) and number of waterbodies (ponds)
available during  the breeding  season.  Annual
comparisons and long-term trend information are
available.

COLLECTION METHODS:

This survey is an aerial plot survey. Individual duck,
goose, and swan populations by species and ponds are
counted on strip transects that total 71,110 kilometers
for an approximately one percent sample of the total
surveyed area. Detectability bias is corrected through
the use of a double-sampling scheme. Waterfowl along
a small portion of the transect lengths are counted from
the ground. These counts represent a census, allowing
the correction of the  aerial counts by  using ratio
estimators. The number of breeding waterfowl for each
species and the number of waterbodies is the target
population.

COLLECTION FREQUENCY:

Data collected on an annual basis.

GEOGRAPHIC COVERAGE:

Includes the fifty states, Yukon Territory, Northwest
Territories,  Alberta,  Manitoba, Saskatchewan,
western Ontario, North and South  Dakota,  and
Montana.

 DEPARTMENT OF THE INTERIOR
 National  Hydrologic Benchmark Network Program
OFFICE:

U.S. Geological Survey
Water Resources Division
Office of Water Quality

SUMMARY PROGRAM DESCRIPTION:

The National Hydrologic Benchmark Network
Program was initiated in 1964 to provide a nationally
uniform basis for assessing long-term trends in the
physical and chemical characteristics of surface waters
largely unaffected by land use activities. Water quality
monitoring is carried out in basins where there are
generally no man-made storage,  regulation,  or
diversion. Groundwater in hydrologic benchmark
basins is not affected by pumping, and the probability
is small that human activity would increase within the
basin.

DATA COVERAGE:

Principal constituents monitored in freshwater and
analyzed for trends are pH, alkalinity, sulfate, nitrate,
phosphorus, calcium, magnesium, sodium, potassium,
chloride, suspended sediment, fecal coliform bacteria,
fecal  streptococcal bacteria,  dissolved oxygen, and
dissolved oxygen deficit.

Trace elements monitored in freshwater and analyzed
for trends are arsenic, cadmium, chromium, iron, lead,
manganese, mercury, selenium, and zinc.

The following radionucleides are also monitored but
have not been analyzed for trends: gross alpha, gross
beta, radium-226, and uranium.

COLLECTION METHODS:

Data-collection stations are maintained at selected
locations to provide standardized records on surface-
and ground-water conditions. A variety of automated
instruments are used to measure and record water
conditions.

COLLECTION FREQUENCY:

Data are collected monthly at four percent of the sites,
bimonthly at  eighteen  percent  of  the  sites, and
quarterly at seventy-eight percent of the sites. Trace
element  collection  is quarterly only,  and
radionucleides are only collected semiannually.
GEOGRAPHIC COVERAGE:

Coverage includes fifty-eight locations in thirty-seven
states.

DEPARTMENT OF THE INTERIOR
National  Land Use and Land Cover Mapping Program
OFFICE:

U.S. Geological Survey
Office of Geographic and Cartographic Research

SUMMARY PROGRAM DESCRIPTION:

As part of its National Mapping Program, the USGS
produces and distributes land use and land cover maps
and digitized data. Land use refers to human activities
that  are directly related  to the land.  Land cover
describes the vegetation, water, natural  surface, and
artificial constructions at the land surface. Associated
maps display information on political units, hydrologic
units, census county subdivisions, and in some cases,
federal land ownership.

DATA COVERAGE:

Land use and land cover areas are classified into nine
major classes: urban or built-up land, agricultural land,
rangeland, forest land, water areas, wetland, barren
land, tundra, and perennial snow or ice. Each major
class is subdivided  into several minor classes, for
thirty-seven minor classes total. For example, forest
lands are further classified as deciduous, evergreen, or
mixed forest land, and water is further  classified as
streams and canals, lakes, reservoirs, or bays  and
estuaries.

COLLECTION METHODS:

Remote sensing methods are used, including satellite
imagery, high-altitude imagery, medium-altitude
remote sensing (1:20,000), and low-altitude imagery.

COLLECTION FREQUENCY:

Data were collected hi the late 1970s and early 1980s.

GEOGRAPHIC COVERAGE:

1:250,000 maps are available for the continental United
States. Digitized data at 1:250,000 scale are available
for most of the East, Midwest, West Coast, and parts
of the Rocky Mountain states and Texas. A few areas,
including Hawaii, are available at 1:100,000 scale.

SUMMARY PROGRAM DESCRIPTION:

The National Stream Quality Accounting Network
(NASQAN) program, started  in  1972, provides  a
nationally uniform basis for assessing large-scale and
long-term  trends  in  the  physical,  chemical,  and
biological  characteristics  of the nation's  surface
waters. Water quality monitoring is carried out at the
stations which are generally located on major rivers at
the downstream end of the accounting unit.

DATA COVERAGE:

Principal constituents monitored in  freshwater and
analyzed for trends are pH, alkalinity, sulfate, nitrate,
phosphorus, calcium, magnesium, sodium, potassium,
chloride, suspended sediment, fecal coliform bacteria,
fecal streptococcal bacteria, dissolved oxygen, and
dissolved oxygen deficit.

Trace elements monitored in freshwater and analyzed
for trends are arsenic, cadmium, chromium, iron, lead,
manganese, mercury, selenium, and zinc.

The following radionucleides are also, monitored at
forty-six sites but have not been analyzed for trends:
gross alpha, gross beta, radium-226, and uranium.

COLLECTION METHODS:

Data-collection stations are maintained at selected
locations to provide standardized records on surface-
and ground-water conditions. A variety of automated
instruments are used  to measure and record water
conditions.

COLLECTION FREQUENCY:

Data are collected bimonthly at fifty-eight percent of
sites and quarterly at forty-two percent of sites. Trace
element collection is quarterly and radionucleides are
collected semiannually. Yearly data summaries are
available for each state.
        GEOGRAPHIC COVERAGE:

        Coverage includes: twenty-one water resource regions,
        213 water resource subregions, 411 monitoring
        stations, and the fifty states plus Puerto Rico.

National Trends Network
OFFICE:

U.S. Geological Survey
Water Resources Division
Office of Atmospheric Deposition Analysis

SUMMARY PROGRAM DESCRIPTION:

The National Trends Network (NTN) for monitoring
precipitation chemistry in the U.S. was formally
established in 1983 (although some monitoring sites
were established in 1978). The NTN is  under the
sponsorship of the U.S. Geological Survey, as lead
agency for deposition monitoring under the National
Acid Precipitation Assessment Program  (NAPAP).
The NTN consists  of 150  stations located
predominantly in rural areas, but in combination with
the  National  Atmospheric  Deposition Program
(NADP), includes more than 200 sites nationwide.

DATA COVERAGE:

Principal constituents monitored  in  precipitation  and
analyzed for trends are pH, specific conductance, hydrogen
ions, sulfate and nitrate ions, ammonium and calcium ions,
and chloride, magnesium, sodium, and potassium ions.

COLLECTION METHODS:

The NADP/NTN monitoring program has developed
criteria and protocols which ensure uniformity in
siting, sampling methods, analytical techniques, data
handling,   and   overall   network   operations.
Precipitation  is collected by wet/dry precipitation
collectors and rani gages. Analytical methods for the
chemical variables measured are: laboratory pH; field
pH; laboratory conductivity; electrometric detection
of  hydrogen (also reported as  pH);  automated
colorimetric  detection   of  ammonium;  atomic
absorption spectrophotometric detection  of calcium,
magnesium,  sodium,  and  potassium;   and  ion
chromatographic  detection of sulfate, nitrate,  and
chloride. Methodologies are described in National
Atmospheric Deposition Program  (1988)  -  See
Publications.

COLLECTION FREQUENCY:

Samples are collected weekly. Data from some sites are
available from 1979.
GEOGRAPHIC COVERAGE:

The entire United States; however, not all states have
stations located within their boundaries. The trend
analysis report covers nineteen stations located mainly
in the eastern United States.

SUMMARY PROGRAM DESCRIPTION:

This program collects and analyzes streamfiow data
from 190 sites in the U.S., Canada, and Puerto Rico;
groundwater levels from  about 200 sites in the
conterminous U.S.; reservoir  contents  from 100
reservoirs  in the U.S. and Canada;  and limited
water-quality data from five sites on major rivers.
These data, or summaries thereof, are published in the
free monthly newsletter, "National Water Conditions."

DATA COVERAGE:

Streamfiow data include maximum,  minimum, and
mean monthly discharge,  and also  maximum and
minimum daily discharges  for the period of record.
Classed data (quartiles) for  the current thirty-year
reference  period (1951-80  at  this  time)  include
monthly, quarterly, and  annual (water-year and
calendar year)  means. Period-of-record monthly
averages, maximums and minimums are available for
groundwater levels, reservoirs, and water quality data.

Data reveal  trends in stream flow and volume (for
example, effects of droughts, floods, and reservoirs on
discharges).

COLLECTION METHODS:

Data are extracted from WATSTORE and the other
sources listed under Databases (below) and are
statistically analyzed to produce trends in national
water conditions.

COLLECTION FREQUENCY:

Frequency includes: monthly means for all streamfiow
with highest, lowest, and last available day of month for
some sites; month end reservoir contents; and month
end groundwater levels.

 National Water Use Information  Program
 OFFICE:

 U.S. Geological Survey
 Water Resources Division
 Program Coordination and Technical Support
 Branch of Water Use Information

 SUMMARY PROGRAM DESCRIPTION:

 The National Water Use Information Program is a
 federal-state cooperative program designed to collect,
 store, analyze, and disseminate water-use information
 both nationally and locally. The program began in 1978
 to  meet the  need for a single source of uniform
 information on water use. The water-use information
 from the program complements long-term USGS data
 on the availability and  quality of the nation's water
 resources.

 The objectives of the program are to determine, on a
 national level, how much fresh and saline surface water
 and groundwater are withdrawn and for what purposes;
 how much of this water is consumed during use; and
 how much water is returned to the source after use.

 DATA COVERAGE:

 Water withdrawals from  surface and groundwater
 sources and consumptive use estimates are compiled
 by state and water resources regions for the following
 water-use  categories:  public  supply,  domestic,
 commercial, industry, mining,  irrigation, livestock,
 thermoelectric power generation, and hydroelectric
 power generation. Trend data are available at five-year
 intervals from 1950 to 1985. Data for 1990 are being
 compiled and will be available in 1992.

 COLLECTION METHODS:

 Cooperating  states  collect  water-use  data  and
 aggregate these data by county and hydrologic unit.
 Most  of the data are derived from mail surveys or
 permit reports required to meet state regulations. The
 point  data are stored-on state-level  databases; the
 aggregated  data are compiled  by  the  USGS  for
 incorporation into the national Aggregated Water Use
Data System (AWUDS).

 COLLECTION FREQUENCY:

National compilations of "Estimated Use of Water in
the United States" have been published by the USGS
since 1950 at five-year intervals. Many states compile
 and publish monthly or annual water use data as part
 of the cooperative program.

 GEOGRAPHIC COVERAGE:

 Water use estimates are compiled for all fifty states,
 Puerto  Rico,  Virgin  Islands,  and the District  of
 Columbia. Data are available for 1985 by county and
 four-digit hydrologic subregion.

 SUMMARY PROGRAM DESCRIPTION:

 The principal  goal of the program is to  develop
 summary level statistics on water resources at the state
 and national levels appropriate for the preparation of
 USGA's biennial report, National Water Summary.
 Each report is oriented  toward  a specific water
 resource theme (e.g., groundwater quality).

 DATA COVERAGE:

 Statistics for major subjects covered at the national and
 state levels include: water availability (e.g., surface and
 groundwater potential, use, and development); water
 quality (e.g., point and nonpoint sources of pollution,
 eutrophication, bottom sediment contamination,
 saline-water intrusion, hazardous wastes, radioactive
 wastes, and acidic precipitation); hydrologic hazards
 and land use  (e.g.,  flooding, land  subsidence,
 sinkholes, erosion,  sedimentation, wetlands, and
 resource development);  .and institutional and
 management activities. Also covered are  seasonal
 hydrologic conditions and hydrologic events such as
 precipitation, streamflow, floods, and storms.

 COLLECTION METHODS:

 Data summarized in the National Water Summary are
 compiled from  existing U.S. Geological Survey and
 other-agency data files.

 COLLECTION FREQUENCY:

 Data are compiled periodically.

 GEOGRAPHIC COVERAGE:

 Entire  United  States, Puerto  Rico,  and Trust
 Territories.

SUMMARY PROGRAM DESCRIPTION:

The  program includes  the  collection,  analysis,
summary, and dissemination of a broad range of data
related to the physical characteristics of the nation's
highway system,  as well as the traffic/travel and
related performance activity which occurs on those
systems.

DATA COVERAGE:

Data  are  compiled  by  the  state  highway and
transportation agencies, using guidelines prepared by
Federal Highway  Administration  (FHWA) and
approved by the Office of Management and Budget.
Data reported to FHWA include characteristics such
as: trafficvolumes; travel estimates (for example, miles
traveled and fuel consumption per vehicle and per
capita); vehicle speeds; distribution of vehicle types
and  weights  by  highway category;  vehicle fuel
efficiency ratings and motor fuel consumption; vehicle
registrations and driver licensing (including revenues
related to latter variables); state and local highway
finance; Federal Highway Trust Fund status; highway
mileage; pavement condition; and accidents. Data also
include personal travel characteristics collected as part
of the Nationwide Personal Transportation Study
(NPTS). Trend data for many of the characteristics
date back to the early 1900s.

COLLECTION METHODS:

Data collection methods vary by program. Some data
are collected by a full census whereas other data are
collected using a statistical sample basis, such as
collection of travel data. Methodologies are generally
described in reference publications listed below.

COLLECTION FREQUENCY:

Highway statistics have been published annually since
1945. Most data are reported on an annual basis with
the exception of  speed data which are  reported
quarterly and traffic volumes/fuel consumption data
which are reported monthly. NPTS data are available
for 1969,1977,1983, and 1990

SUMMARY PROGRAM DESCRIPTION:

The Marine  Pollution  Retrieval  System contains
details of pollution incidents in the coastal zone where
the Coast Guard is the on-scene coordinator and in the
inland zone where Coast Guard personnel assist an
on-scene coordinator  for the  Environmental
Protection Agency (EPA).

DATA COVERAGE:

Records are kept on: oil spills (number, volume, date,
substance, costs for federally-funded responses, and
case  histories);  spills  of  hazardous  substances
(substance name, CHRIS ID code, physical/chemical
properties); geographic information (latitude  and
longitude and/or river mile number, waterbody name,
city, state, and, where applicable, vessel name and ID);
facility information  (name, address, ID codes); and
transportation information (air, land, inland, and
coastal waterways).

COLLECTION METHODS:

The Federal Water Pollution Control Act, as amended
(Section 311), and Executive, Order 11735 require that
any discharge  of an oil or a hazardous substance in a
harmful quantity be reported to the U.S. Coast Guard.
Data are reported for actual spills only, i.e., discharges
which entered the water. Incidents which are reported
to EPA  and occurred in waters under Coast Guard
jurisdiction are also compiled.  A  sample data
reporting form  is  provided in the Coast  Guard
publication listed below.

COLLECTION FREQUENCY:

Data are collected when spills occur.

SUMMARY PROGRAM DESCRIPTION:

The  Air Pollution Control Program collects  and
analyzes data on ambient air quality and air pollution
levels and compares them to National Ambient Air
Quality Standards (NAAQS).

DATA COVERAGE:

Ambient concentrations of the following criteria air
pollutants are monitored and analyzed for ten-year
trends and recent changes: sulfur dioxide; nitrogen
dioxide; carbon monoxide; total suspended
particulates; ozone; and lead.

Emission estimates are available  for  particulates,
sulfur oxides, nitrogen oxides, reactive volatile organic
compounds, carbon monoxide, and lead. Data are
broken  down  by  the  following emission sources:
transportation   (e.g.,  motor  vehicles,  aircraft);
stationary fuel combustion (e.g., coal, natural gas);
industrial processes (e.g.,  copper, pulp mills); solid
Waste disposal; and miscellaneous sources (e.g., forest
fires, agricultural  burning). Air  quality trends  for
major urban areas are provided.

COLLECTION METHODS:

 Ambient air quality conditions are based upon actual
direct measurements. The data are analyzed for trends
and  these trends are supplemented with trends for
nationwide emissions,  which are  based upon  best
available engineering calculations. Data are collected
and reported to EPA by state and local agencies.

COLLECTION FREQUENCY:

Data are collected hourly and daily. Estimates are
provided for 1940, 1950, 1960, and 1970 to give an
historical perspective  on national  air quality and
pollutant emissions and for 1975 to present as an
indication of recent trends.

GEOGRAPHIC COVERAGE:

All fifty states, with metropolitan  statistical areas
(population greater  than 500,000) more  heavily
analyzed.

 SUMMARY PROGRAM DESCRIPTION:

 The Long-Term Monitoring Project (LTMP) was
 initiated hi  1983  to  monitor trends in low-acid
 neutralizing capacity (ANC) surface waters across a
 gradient of acidic atmospheric  deposition. LTMP
 operates with  cooperators affiliated with federal
 agencies and universities hi six geographic regions. The
 LTMP was proceeded by the National Surface Water
 Survey (NSWS) and continued after it.

 DATA COVERAGE:

 Variables monitored include pH, ANC, calcium,
 magnesium, p'otassium, sodium, sulfate,  chloride,
 nitrate, dissolved organic carbon, and aluminum.
 Trend data are not available because of the short
 period of record (since 1983).

 COLLECTION METHODS:

 See Publications.

 COLLECTION FREQUENCY:

 Data are collected seasonally.

SUMMARY PROGRAM DESCRIPTION:

The National Surface Water Survey consists of two
parts: the National Lake Survey and the National
Stream Survey.

The purpose of the National Lake Survey is to quantify,
with known statistical confidence, the current status,
extent, and chemical and biological characteristics of
lakes in regions of the United States that are potentially
sensitive to acidic deposition.

The purpose of the National Stream Survey (NSS) is to
determine the percentage, extent,  and location of
streams in the United States that are presently acidic
or have  low acid-neutralizing capacity  and  may,
therefore, be susceptible to future acidification, as well
as to identify streams that represent important classes
in each region for possible use in more intensive studies
or long-term monitoring. The NSS provides an
overview of stream water chemistry in regions of the
United States that are expected,  on the basis of
previous alkalinity data, to contain predominantly low
acid-neutralizing capacity waters.

DATA COVERAGE:

Variables   monitored include:  acid  neutralizing
capacity (ANC), aluminum, ammonium, base cations,
conductance, major ions, metals, nitrate, organics, pH,
and sulfate.

COLLECTION METHODS:

A randomly selected subset of lakes was sampled using
appropriate methods. The sample results  were  then
weighted to estimate the chemical compositions of lake
populations with known  confidence. Uncertainties
with  time of  sampling,  spatial  'variability,  and
population definition are included in specific research
projects to improve confidence in estimates.

The NSS employed a randomized, systematic sample
of regional stream populations and used rigorous
quality assurance protocols for field sampling and
laboratory chemical analysis.
        COLLECTION FREQUENCY:

        "Index" sample taken at the time of the fall overturn
        for lakes and high and low flow for streams.

        GEOGRAPHIC COVERAGE:

        Northeastern, Southeastern, Upper Midwest, and
        Western United States for lakes, and Middle Atlantic,
        Southeast, and Southern Blue Ridge Province for
        streams.

 Environmental Radiation Ambient Monitoring System
 OFFICE:

 Office of Radiation Programs
 National Air and Radiation Environmental Laboratory

 SUMMARY PROGRAM DESCRIPTION:

 The Environmental Radiation Ambient Monitoring
 System (ERAMS) was implemented in 1973 and has
 operated  continuously  ever  since. The  ERAMS
 monitors, nationally, radioactivity associated with air,
 drinking water, surface water, and milk. Prior to 1973
 and dating back to 1960, several national networks of
 environmental radiation  sampling stations  were
 operated by the  U.S. Public Health Service. When
 EPA was established, these  networks  were
 consolidated and modified into the single national
 network now known as ERAMS.

 DATA COVERAGE:

 Data for pasteurized milk include concentrations of:
 Iodine(I)-131, Barium(Ba)-140, Cesium(Cs)-137,
 Potasium(K)-40, Strontium(Sr)-89, Sr-90, and
 Carbon(C)-14. For  airborne particulates:
 Geiger-Mueller field estimates, gross beta, gamma
 scans,  Plutonium(Pu)-238, Pu-239,  Pu-240,
 Uranium(U)-234, U-235, U-238, and Krypton(Kr)-85.
 For precipitation: Hydrogen(H)-3, gross beta, gamma
 scans, Pu-238, Pu-239, Pu-240, U-234, U-235, and
 U-238. For drinking water: H-3, gamma scans, gross
 alpha, gross beta^ Radium(Ra)-226, Ra-228, Sr-89,
 Sr-90, Pu-238, Pu-239, Pu-240, U-234, U-235, U-238,
 and 1-131. For surface water: H-3 and gamma scans.

 COLLECTION METHODS:

 The ERAMS program includes 332 sampling stations
 distributed throughout the fifty states, the Virgin
 Islands, Panama Canal, and Puerto Rico. Stations were
 selected to provide optimum radiation source and
 population coverage. Many  stations  are located
 downstream from nuclear power plants.  See
 Publications for description of methods.

 COLLECTION FREQUENCY:

Analytical frequency is different for different analyses,
ranging from twice weekly for gross beta in air to every
two years for Krypton-85. Analytical frequencies for
specific radionuclldes can be found in the  quarterly
publication "Environmental Radiation Data" and the
 "Environmental  Radiation  Ambient  Monitoring
 System (ERAMS) Manual".

 GEOGRAPHIC COVERAGE:

 Sampling stations are sited throughout the fifty states,
 the Virgin Islands, Panama Canal, and Puerto Rico.

SUMMARY PROGRAM DESCRIPTION:

Data are collected through survey and  (regulated
entities) reporting mechanisms on hazardous and
non-hazardous ("solid")  wastes generation and
management. Various capabilities are available for
retrieving and  analyzing these  data. Generally, the
information available consists of regulated entities and
waste volumes generated and managed.

DATA COVERAGE:

Hazardous Wastes: Statistics are available by site,
state, and nationally for wastes generated and
managed (treatment, storage, disposal or recycling).
Data are available from three sources:

    (1) Biennial Report — number of generators,
    amount of wastes generated; number of waste
    management facilities;  amount  of  wastes
    managed (by EPA region, by state); inter-state
    waste flow; amounts of waste generated by waste
    type; and amounts of waste managed by waste
    management method.

    (2)  National  Survey  of  Hazardous  Waste
    Generators  — Though similar to the Biennial
    Report, additional detail is provided, basically on
    waste  characteristics  and waste  producing
    processes.

    (3) 1986 National Survey of Treatment, Storage,
    Disposal and Recycling (TSDR)  Facilities  —
    Also  similar to the Biennial Report, but it
    provides  additional  detail  on  the   waste
    management processes.

Non-Hazardous Wastes:  National statistics  are
available for wastes generated and managed. The data
cover the industrial sector and the municipal landfill
sector.

Industrial: Statistics  are  available for  1985  on the
amounts of non-hazardous waste by type of industry
(e.g., textile, pulp and paper, water treatment),
management  practices (e.g., landfills, surface
        impoundments, incineration, recycling), and by size of
        establishment.

        Municipal Landfills: Trend data are available  on:
        quantity of materials generated in the municipal waste
        stream (including paper, glass, metal, and plastics,
        rubber, leather, textiles, wood, and other nonfood
        waste, and food, yard, and miscellaneous inorganic
        waste); quantity and type of waste accepted and
        refused (e.g., household, commercial, construction);
        size and capacity of facility; monitoring systems; types
        of liners and covers; hydrological characteristics and
        proximity to drinking water supplies; and number of
        persons using these sources.

        COLLECTION METHODS:

         Surveys and Reporting.

        COLLECTION FREQUENCY:

        Data collection and reporting frequency range from
        once to every two years.

        GEOGRAPHIC COVERAGE:

        Entire United States.

 SUMMARY PROGRAM DESCRIPTION:

 The Toxics Release Inventory (TRI) is a mandatory
 annual inventory of the release of 328 toxic chemicals
 to air, water, land, and off-site disposal from more than
 17,000 manufacturing facilities across the country.

 DATA COVERAGE:

 Data collected include: facility information, including
 Resource Conservation and  Recovery Act and
 National Pollution Discharge Elimination System
 permit numbers; pounds/year emissions information
 for air, water, and land disposal, and off-site transfers
 of wastes; treatment processes and efficiencies; and
 waste reduction data.

 COLLECTION METHODS:

 The emergency Planning and  Community  Right-
 to-Know Act requires manufacturers to report to EPA
 and to states the amounts of over 300 toxic chemicals
 that they release directly to air, water, or land, or that
 they transfer to offsite facilities that treat or dispose of
 wastes. Facilities are required only to report data that
 are already known or reasonably ascertainable to them,
 e.g., engineering estimates. They are not required to
 measure or otherwise verify the data  they submit.
 Survey submissions on forms are tabulated and stored
 by EPA  on computer tape or disc, and the data are
 compiled into an annual inventory of releases and
 transfers.

 COLLECTION FREQUENCY:

 Data are collected yearly through mandatory industry
 reporting.

 GEOGRAPHIC COVERAGE:

 Entire United States.
