                                      PREFACE
       This report, an Inventory of Exposure-Related Data Systems Sponsored by Federal
Agencies, is a compilation of information on federally managed data systems that contain
exposure  information.  These  systems access collections of analytical results that assess
environmental  media such as  air,  soil, or water, as well as analytical results from food,
human samples, or hulk chemicals.  The Inventory focuses on data systems that:

       •     Contain information on a large geographic area (i.e., national, regional, state,
             or region of a state—excluding individual research studies of limited scope);
       •     Have data or summary documents that are generally available for research or
             other purposes; and
       »     Are supported, at least in part, by public funds.

       The Inventory emerges from-the premise that the availability and quality of exposure
data is a  central  issue in environmental studies. Objective and quantifiable exposure data
are needed to perform risk assessments, to evaluate risk management programs, to evaluate
the status of and trends in exposure, and to perform epidemiologic studies and surveillance
activities. The first step in encouraging the development of high-quality exposure data is to
determine and  characterize the data systems that already exist.

       This report consists of  a brief overview of the purpose, scope, method, limitations,
organization, and findings of the inventory, followed by detailed summaries of each data
system.  The Inventory is organized into two parts:  Part I contains descriptions of data
collection systems that collect  source data; Part n  contains descriptions of data  handling
systems that provide easy and flexible access to data available in other data systems.  (This
distinction is not meant to imply that data collection systems do not provide easy and flexible
access to  data.) If a data system collects any source data, it is listed in the data collection
system section regardless of the data handling capabilities of the system. Summaries within
each section are in alphabetical order by name of the data system.  In Part I, the detailed
                                         Vlll

-------
description of each data collection system includes the objectives and coverage of the system,
summary of environmental data, sample design and analysis, database characteristics, and
contact persons for additional information.      (For some data systems detailed information
was not available; in these instances a brief description is provided.) In Part n, the detailed
write-up of each data handling system describes the coverage of the system, the data sources
included, data presentation, and data availability.

       In addition, there are four appendices.  Appendix A contains the names and acronyms
(if any) of the data systems.  Appendix B lists the data systems by agency.  Appendix C
contains the questionnaire  that was sent to each  of the  database managers. (Responses to
the questionnaire and  a great deal  of additional information provided by these individuals
formed the basis of the summaries in this  Inventory.)  Appendix D contains additional data
systems  that  support  and  quantify  environmental  exposure  assessment by  providing
information such as emission factors and  food consumption data.  In addition, a listing of
chemicals found in the data collection systems was compiled in which the chemicals are listed
by data collection system name and media.  Appendix E describes how this list was compiled;
the listing itself is on a diskette accompanying this document.

       This Inventory served as the background document for the workshop entitled "Making
Use of Environmental Exposure Databases."   This workshop, which was  held in January
1992, was jointly sponsored by the Environmental Protection Agency, the Agency for Toxic
Substances and  Disease Registry, and the National  Center for Health Statistics  of the
Centers for Disease Control.  The workshop focused on four  questions:   How are these
databases being used?  Are data available to document exposures for both the general
population and high risk groups?  What  critical  data are not available?  Should existing
databases be modified,  or should new databases be created to address data gaps?

       This project was initiated by the Task Force on Environmental Cancer and Heart and
Lung Disease and  completed under the joint direction of the Environmental Protection
Agency, the National Center for Health Statistics of the Centers for Disease Control, and the
Agency for Toxic Substances and Disease Registry.

       The Inventory represents the efforts of many individuals in the federal government
who completed the questionnaires, the staff of Eastern Research Group, Inc. (especially Leslie
Beyer, Linda Stein, David Mellard,  and Janice Pacenka), Haluk Ozkaynak, Ph.D., and the
following memhers of a steering committee whose tenacity resulted in the completion of this
Inventory:   Ken Sexton, Sc.D., Environmental Protection Agency; Sherry Selevan, Ph.D.,
Environmental Protection Agency; Jeffrey Lybarger, M.D., Agency for Toxic Substances and
Disease Registry; and Thomas Miller, Environmental Protection Agency. The efforts  of all
of these individuals are greatly appreciated.

                                       OVERVIEW
INTRODUCTION

       Federal, state, and local officials face increasing public demand for information on exposure
to toxicants in the environment and their  possible adverse health effects.   The potential for
exposure exists in the air we breathe, the water we drink, the food we consume, and the soil and
dust we contact.  With industrialization and new technological developments, both the quantity and
types of substances in the environment are increasing.

       To  conduct environmental  studies or to evaluate program effectiveness,  officials and
researchers need quality data on potential toxic exposures.  The premise of this project is that data
systems exist that could be used to meet these needs.  Federal and state agencies,  for example,
maintain environmental exposure data systems, which are typically generated for specific purposes
(e.g., regulatory).  In some instances, the quality of the data is not optimal.  However, of equal
concern to this project is the presumption that the use of existing quality data is not optimal.  This
Inventory was generated  as a means to learn more about existing data systems and the potential
for new and innovative uses of the data in them.
PURPOSE
       This Inventory is intended to aid policy makers, program managers, and researchers, as well
as concerned citizens,  in identifying  potential sources  of exposure information.   Exposure
information is needed by epidemiologists, risk assessors, risk managers, and policy makers to
evaluate the  status and trends in exposure assessment and disease surveillance.  The Inventory
should broaden the scope of available information  for these individuals  and help them identify
potential data sources. The Inventory, however, was not designed to answer all questions that might
be asked about a data system.  Instead, limited characteristics of these resources are described in
the Inventory. It is intended that users of the Inventory will seek additional information from the
contact persons listed in the description of each data system.

                                            -1-

SCOPE
       In August 1981, the Task Force on Environmental Cancer and Heart and Lung Disease
published the Directory of Exposure-Related Data Bases. This report included information on 13
information resources, which were largely federally managed.  Criteria for inclusion were that the
resource contain numerical  or qualitative data  that  assist  in  exposure assessment, contain
observational data, involve ongoing or periodic data collection, and be publicly accessible.  Since
the publication of the Directory in 1981, efforts to collect environmental data have  expanded
enormously.  The purpose of this current Inventory is to expand and update the Directory.

       This Inventory describes data systems that contain exposure-related information and are
managed and funded by the federal government.   (Although  many state- and locally-sponsored
databases contain valuable exposure-related information, the scope of this Inventory was limited
to federal systems due to lack of resources.)  Exposure-related information was defined broadly to
include analytical  results that assess food, human samples,  or bulk chemicals;  or  assess  an
environmental media such as air,  soil, or water.  Occupational exposure measurements were
excluded to limit the size and complexity of the project.

       The Inventory focuses on data systems  that:

       •     Contain data on a large geographic area (i.e.,  national, regional, state, or region of
              a state—excluding individual research studies of limited scope);
       •     Have data or summary  information documents that are generally  available  for
              research or other purposes; and
       •     Are supported, at least in part,  by public funds.

With some exceptions, the data systems included in this Inventory contain measured,  as contrasted
to estimated,  data.  The exceptions have been included because  they have been widely used to
characterize potential human exposures.
       In contrast to the previous Directory, this Inventory does not include resources that focus
on lists of citations to other forms of information such as articles, reports, or databases.  Further,

                                            -2-

-------
this Inventory does not focus on databases that contain only production volume data. The reasons
for these limitations were largely to make the scope of this project achievable.
METHOD

       A five-member steering committee  directed this project.  Its members  represented the
Environmental Protection Agency, the National Center for Health Statistics of the Centers for
Disease Control, and the Agency for Toxic Substances and Disease Registry. A wide range of data
sources can be  used in  exposure assessment.   These include production volumes, emissions
inventories, ambient concentration models and measurements, micrdenvironmental concentration
models and measurements, human activity patterns, personal exposure measurements, and biological
measurements.  To assist defining the scope and contents of this Inventory, a variety of previous
documents  were consulted, and meetings were held with officials from the Agency for Toxic
Substances  and Disease  Registry,  Environmental Protection Agency, National  Center for

       Many documents provided guidance on the content for this Inventory, including the previous
inventory, Directory of Exposure-Related Databases.   In addition, recent documents were reviewed
for applicability of content, identification of needs, and scope. These documents included:
       Environmental Health: A Plan for Collecting and Coordinating Statistical and Epidemiologic
       Data. 1980. National Center for Health Statistics. U.S. Department of Health and Human
       Services. DHHS Pub. No. (PHS) 80-1248. U.S. Government Printing Office:  Washington,
       DC.

       After reviewing and discussing these and other documents, the steering committee felt that
sampling strategies for occupational exposures were substantially different from those used for most
other environmental data. Consequently, the steering committee decided that the Inventory would
focus on nonoccupational exposures so as to limit the scope and complexity of the project.

       The steering committee 'also decided to focus efforts for this Inventory on systems that
contained information on a large geographic area. This decision necessarily eliminated pilot studies
and targeted research projects.

       Several relevant inventories were reviewed  for format and content as guidance for this
project.  These inventories included:

       Abramowitz, J.N., D.S. Baker, and D.B. Tunstall.  1990.   Guide of Key Environmental
       Statistics in the U.S. Government.  World Resources Institute.

       Services.  U.S. Government Printing Office:  Washington, DC.
       Information  Resources Directory.  1989.   Environmental Protection  Agency.   Office of
       Information and Resources Management.

       Pub. No. (PHS) 89-1255-1.  U.S. Government Printing Office: Washington, DC.

       Several meetings were held with representatives from the agencies noted above to identify
database characteristics of most interest and to develop a questionnaire.  The questionnaire was
then sent as a pilot project to sk data systems, chosen because they represented a wide variety of
data system characteristics. The questionnaire was subsequently revised and sent to the managers
of over 100 databases. The questionnaire and instructions are included as Appendix C.
       The questionnaire  sought information  on the purpose of the data system, geographic
coverage, site selection, source and dispersion information, sample collection and quality control,
data preparation and availability, and toxicant and media assessed. In addition, system managers
                                            -4-

were requested to provide background information and descriptive reports. Given the scope of the
systems included and the type of information requested, no satisfactory short questionnaire could
gather all the information needed to develop the summaries provided in this Inventory. Therefore,
the collection of this information and followup clarification required multiple contacts with the data
managers.  Once written, each  description was  reviewed by Ms. Beyer or Ms.  Stein (Eastern
Research Group, Inc.), Dr. Ozkaynak (Harvard University), and Dr. Wagener (National Center for
Health Statistics).
LIMITATIONS

       No assurance can be given that all inscope data systems have been included.  Time and
resource limitations prevented exhaustive canvassing to assure that all appropriate systems were
identified.  The inclusion list was sent to government officials, some of whom provided us with the
names of additional data systems. Many system managers, however, ignored the original request
for information (i.e., the questionnaire) and followup mailings.  In such cases, staff attempted to
obtain information via telephone conversations  or  from descriptions available  in reports or
brochures.

       As noted above, an important limitation of an Inventory including 95 data systems is that
detailed information cannot be provided.  Hence it is important for the user to seek additional
information from the contact person listed as part of each data system description.

       One problem that arose in this survey was that over time systems have changed names, some
multiple  times.  In those instances,  we have listed both former and current names.   Table 1
summarizes this information and provides cross-references for the user.

ORGANIZATION OF THE INVENTORY

       In the synopsis that follows, two types of data systems are discussed: data collection systems
and data handling systems.   Data collection systems are systems  that collect  data (mostly
environmental sample results, but some estimated data are included, too). Data handling systems
are those systems that coordinate and/or compile data from multiple data collection systems and
provide the user with easy, but sophisticated, statistical  and graphical representations of data.  In
some instances, this distinction is blurred because some data collection systems also provide flexible
analytical features.

       Descriptions for the data collection systems, which are located  in Part I of the Inventory,
contain information on the purpose of the data system, geographic coverage, site selection, sample
collection and quality control, data availability, and toxicant and media assessed. The data handling
system descriptions, located in Part II, are more cursory; they describe coverage of the system, data
sources included, data presentation, and data availability.  Although Part II descriptions do not
provide details on the component databases, they do refer potential users of these files to writeups
on specific component databases  found in Part I.  Any system that has primary data collection
responsibilities was included in Part I as a data collection system.

       Also provided in the Inventory are appendices A to D.  Appendix A contains two tables:
one lists the systems by name and acronym; the other lists them by acronym and name.  Appendix
B cross-references the systems by the federal agencies  that manage them. Appendix C contains the
questionnaire.  Appendix D presents  summaries of additional data systems that do not contain
analytical measurements, but contain information that support environmental exposure assessment.
Examples of this type of information include emission factors, fate and transport models, and
surveys of consumer usage of products or consumption of various foods.  Summaries of 17 such
systems are located in Appendix D.  Appendix E  contains an introduction to the listing of the
specific chemicals found in the data collection systems.  In this listing, the chemicals are listed by
data collection system name and media; the listing itself is on a diskette accompanying this
document.

SYNOPSIS OF DATA SYSTEMS INCLUDED IN THE INVENTORY

       The American public is most often interested in environmental pollution because of concern
for possible adverse health effects.   However,  evaluating the relationship between potential
exposures and the potential for adverse health effects is a complex process. Figure 1 graphically
outlines some aspects of this evaluation. The focus of this Inventory is on the exposure assessment
portion of this evaluation process.

       The  data systems included in this Inventory primarily collect and compile  analytical
measurements.  Systems that  were based on models or occupational measurements were  not
included.  Further, the Inventory was restricted to those systems that evaluate large geographic
areas.  The most frequent reason for excluding a system was the lack of geographic information.

       This Inventory includes detailed descriptions of 67 data collection systems managed by 17
lead government agencies, the United Nations Environment Programme, and the World Health
Organization (WHO). Twelve data handling systems are also included. The summary statistics that
follow are based on those data collection systems in Part  I for which detailed information was
available.

       Table 2 presents  the number of data collection systems that provide each type of data
included  in the  Inventory.   The majority (54) of the  data  systems  contain  environmental
concentration  measurements.  The geographic coverage of most of the included data collection
systems was national (44 out of 67).  Given that only databases encompassing a large geographic
area were included, this bias towards national systems is not surprising.  Although the coverage was
national, the sampling strategy differed from system to system.  Few systems measured the same
toxicants in the same media.

       The primary  objective of the data collection systems was most often monitoring (36 data
collection systems). Regulatory support was the primary focus of 19 systems, and research was the
primary objective of 29 systems.  Six were legally required,  but not for regulatory purposes.

       Of specific concern for this Inventory was the level of detail provided as location identifiers.
Table 3 lists various identifiers used by these systems and the number of systems that use those
identifiers. As can be seen, the most frequent identifiers used were state and latitude/longitude (52
and 44 data collection systems, respectively). This will be important when linkage with other data
systems is contemplated. The data collection frequencies are given in Table 4. Many of the systems
collected data yearly.

       The number  of databases surveying each media assessed is presented in Table 5. Thirty-
three of the databases surveyed water, while 31 surveyed air. The classes of toxicants measured are
shown in Table 6. Inorganic compounds (e.g., metals) were most frequently measured followed by
pesticides, volatile organic compounds, semi-volatile organic compounds, andPCBs. Of course, the
class of toxicant measured is affected, in  part, by  the media assessed.  In addition, the toxicants
assessed depend on the applicable  legislation and  available laboratory  techniques.   Table 7
summarizes selected characteristics of the data collection systems (i.e., period of data collection,
geographic coverage, media covered, and class of chemicals included).  Table 8 lists the specific
media assessed (e.g., ground water, bulk chemicals, dust), for each data collection system.
ADDITIONAL INFORMATION RESOURCES

       In the course of this project, several information resources came to our attention that
provide the user with a comprehensive listing of available  data  systems  and other forms of
information.  Some of these information resources that are sponsored by federal agencies are listed
below. This list is by no means exhaustive.
       EARTH SCIENCE DATA DIRECTORY (ESDD'i
       ESDD is a guide to databases in the fields of earth science and natural resources. Each
record describes a unique database including its geographic coverage, type of access, time span, and
contact  person.  ESDD includes information on over 2,000  databases created by government
agencies, academic institutions, and private sector efforts. ESDD is available on compact discs that

Objectives and Coverage:                       .

       Under the 1990  Clean Air Act Amendments, precipitation samples from geographically
representative sites in non-urban areas that are at least 50 km inland from large water bodies must
be tested for constituents that contribute to and comprise acid precipitation.  The measurement of
acid precipitation became  a major research objective under the National Acid  Precipitation
Assessment  Program (NAPAP) in the  early 1980s (see NAPAP database). The objective of ADS
is to report annually on the status and trends of acid precipitation and, if possible, to determine the
effects of controls placed on sulfur dioxide emissions.  The database focuses on rural areas and
certain sensitive  ecosystems (e.g., crops, forests). In addition to being legally required under the
Clean Air Act, ADS data are often used for research purposes.
Summary of Environmental Data:

Media:  Water (precipitation)

-------
Sample Design and Analysis:

       The sampling program was organized in 1978 by the National Acid Deposition Program-
National Trends Network (NADP-NTN).  NTN is comprised of five contributing networks made
up of government and utility representatives from the United States and Canada, including: the U.S.
Department of Energy;  the Canadian Acid Precipitation Monitoring  Service  (Atmospheric
Environment Service);  the  Ontario Ministry of the Environment;  the Electric Power Research
Institute's Operational Environment Network (United  States); and the NADP-NTN sample
collection/laboratory subnetwork, which contributes  data to the overall project.

       Rainwater is collected from 200 monitoring sites located in  rural areas and near  sensitive
ecosystems across the contiguous United States and the southern portion of Canada.  All of the
contributing networks analyze samples for the compounds of interest: NH3+, NO3", SO4=, K+, H+,
C&++, Mg+, Na+,  and Cl".   Some of the networks also analyze for certain metals, but this is not
required under the program.

       Individual networks  are responsible for their own sample collection and analysis based on
a common set of sampling protocols.  A task force within NADP-NTN, the Universal Deposition
Decision Committee, issued guidelines on how sampling locations should be determined (e.g.,
geographic representativeness; primarily rural areas;  and particularly sensitive ecosystems) and how
samples should be taken.

       20250, (202) 447-2324
Objectives and Coverage:

       The objective of the Agricultural Chemical Usage database is to quantify the amounts of
agricultural chemicals, including pesticides and fertilizers used annually in major crop-producing
states. These data collection survey was developed and funded as part of a multi-agency program,
the Pesticide Data Program, established to meet the 1989 President's Water Quality Initiative to
protect groundwater  and surface water from contamination by fertilizers and pesticides.  This
program is designed to upgrade the reliability of pesticide use data and the quality of information
on pesticide residues in food.  USDA's National  Agricultural Statistics Service (NASS) is
responsible for collecting data on on-farm pesticide use. These data will be used to support water
quality  programs and assist in identifying pesticides of interest to  EPA  for  inclusion in its
monitoring  program.  These data will also be used by USDA's Economic Research Service to
estimate the economic implications  of agricultural pesticide use.

       Two surveys have thus far been conducted by the NASS to provide comprehensive statistics
on agricultural  chemical use.  Both were conducted in 1990 and will be performed annually or
biannually depending on the type of crop.  The first survey was  conducted for field crops  - corn,
cotton,  potatoes, rice, soybeans, and wheat.   The second survey was conducted for vegetables,
melon,  and strawberries.  These surveys  include use information for all agricultural chemicals,
including fertilizers, pesticides (which include insecticides, fungicides, miticides, nematicides, soil
fumigants, herbicides, growth regulators, defoliants, and desiccants), and plant nutrients.
Summary of Environmental Data:

Media:  Bulk chemicals

Classes of compounds: Pesticides, fertilizers

Type of data available: Summary statistics on specific agents

Estimation versus observational data:  Estimated data of total amount of chemicals used annually
       by farmers in selected states
                                            1-5

-------
Sample Design and Analysis:

       Personal interviews were conducted with farmers regarding annual pesticide and fertilizer
use.  Responses were based on farmers' records if available (records are required for restricted use
pesticides; some states may require that records for other chemicals be kept; extension service
offices encourage farmers to document usage).  Sites are selected based on crop and state.  Farms
producing major crops (field crops and 40 vegetable crops) were selected in certain states from a
comprehensive sampling base developed  by USDA that  reflects a statistically  reliable random
sample of the population of farmers in each state selected. Thus, the estimates were statistically
representative of chemical use on targeted crops in the surveyed states. Data on the individual farm
level are confidential; therefore, state-based  averages  are  reported.  Sampling variability and
associated confidence limit estimates, and non-sampling errors are discussed in each survey report.
Surveys for fruit and nut crops are planned.

       For the 1990  field crop survey, 15,025 sample fields were included based on a random
sample of fields in which the probability of selecting a particular field was directly proportional to
the total acres planted to that crop in a given  state.  The number of states in which fields were
selected varied by crop. For corn, farm fields in 47  states were surveyed; for cotton, 6 states were
represented;  for potatoes, 11 states; for rice, 2 states; for soybeans, 29 states; for winter wheat, 12
states; for spring wheat, 4 states,  and for durum wheat, 1 state.

       For the 1990 vegetable, melon, and strawberry crop survey, 4 states were represented. The
sample population consisted of an NASS list of vegetable farms from each state in the survey. The
sample was a stratified systematic sample; vegetable  farms were partitioned into mutually exclusive
strata, and each state had a unique set of strata  priorities. Obtaining a state-level estimate was the
criterion used to project final sample sizes.  The  vegetable survey collected data  on  chemical
application, and the NASS converted the product information to an active ingredient level.

       Triangle Park, NC  27711, (919) 541-5448       	
Objectives and Coverage:

       The AFS contains aerometric emissions and regulatory compliance data on air pollution
point sources (individual facilities) monitored by EPA and state and local agencies. Information
is available on operating status, and descriptive and parametric data are provided for stacks and
other emissions points and processes within  a facility.   Continuous emissions monitoring data,
asbestos activities, and information on landfills for some sites may be found in AFS. Some of the
data are confidential. AFS replaced the National Emissions Data System (NEDS), which provided
information on point and area sources, and the Compliance Data System (CDS), which included
information such as compliance status and action status (see separate entries on NEDS and CDS).
AFS point source data are used by states to prepare State Implementation Plans (SIPs), by EPA's
National Air Data Branch to calculate estimates of national annual air  emissions, and by other
regulatory agencies and academic and environmental organizations. Also see the separate entry for
AIRS in Part II of this inventory for further information.
 Summary of Environmental Data:

 Media: Air (point sources)

 Classes of compounds:  Primarily criteria pollutants and particulates; also information on inorganic
        compounds, VOCs, and semi-VOCs

 Type of data available: Individual data entries and summary statistics are available on specific
        agents

 Estimation versus observational data: Both observational and estimated data
                                           1-8

-------
 Sample Design and Analysis:

       The AIRS Facility Subsystem includes data on more than 100,000 point source facilities
 nationwide.  Point sources emitting more than 100 tons per year of criteria pollutants other than
 lead and CO must  report actual or estimated annual emissions  data; reporting requirements  for
 lead begin at 5 tons per year, and for CO at 1,000 tons per year.  AFS contains more compliance
 than emissions data. Emissions estimates from 1985 to the present are available at process-specific
 levels and are accumulated for plant totals.

Contact Person: Jacob Summers, U.S. EPA, OAQPS, National Air Data Branch, MD-14, Research
       Triangle Park, NC 27711, (919) 541-5695
Objectives and Coverage:

       The Air Quality Subsystem of AIRS (see an overall description of the AIRS database in
Part II) contains  measurements  of ambient  concentrations  of air  pollutants  and associated
meteorological data, primarily from the State and Local Air Monitoring Stations (SLAMS) and
National Air Monitoring Stations (NAMS) networks (see separate entries for SLAMS andNAMS).
Other sources for AQS data include: Special Purposes monitoring sites  established by state and
local agencies (e.g., to determine concentrations of a pollutant in specific areas), the National Park
Service  monitoring  sites, the Tennessee  Valley Authority, and private industry (through state
reporting).  AQS replaces and upgrades the previous  Storage and Retrieval of Aerometric Data
(SAROAD) database; for example, through AQS, states now have direct access to the system for
both submittal and retrieval of data.  The Air Quality Subsystem contains four types of data:
monitoring site data (e.g., site location and operation); raw data (individual values of pollutant
concentrations or meteorological conditions); summary data; and precision and accuracy data (for
air quality monitors).

       Although AQS contains virtually all the data that was previously in SAROAD (either on-line
or on tape), site IDs were changed when SAROAD data was converted to AQS.


Summary of Environmental Data:

-------
Sample Design and Analysis:

       The Air Quality Subsystem includes approximately 20,000 sites in 50 states.  Monitoring
depends on  federal regulations regarding  population, pollutant sources, geographical area,  etc.
Pollutants monitored vary according to site and year.  40 CFR Part 58 specifies minimum
monitoring requirements for criteria pollutants.  For CO, NO2, SO2, and ozone,  sampling is
performed using continuous monitors, and data are reported as hourly averages.  For lead  and
particulates, 24-hour samples are collected and reported as a 24-hour average concentration.

       (301) 975-3112
Objectives and Coverage:

       The Alaskan Marine Mammal Tissue Archival Project was initiated in 1987 to establish a
representative collection of tissues from Alaskan marine mammals for future contaminant analyses
and documentation of long-term trends in environmental quality. This project is one of the many
activities of the National Biomonitoring Specimen Bank (see  separate entry in Part II  of this
Inventory). Since most marine mammals are at or near the top of the food chain, chemical analysis
of their tissues may be useful in determining whether bioaccumulation of contaminants associated
with human industrial activities is occurring in the marine food chains of the Arctic. In addition,
some of the native population of Alaska depend upon such animals for a substantial portion of their
diet. Therefore, the contaminant levels found in marine mammals may have health implications
for the human population occupying these regions. To date, 65 specimens of blubber, kidney, and
liver have been collected from northern fur seals, ringed seals, belukha whales, bearded seals, and
stellar sea lions from 6 sites in Alaska. (Muscle tissue was also collected from northern fur seals
in 1987 only. Additional species and/or new sites are planned for the project each year.

       Detailed information was not available at the time of publication.

Contact Person: Richard J. Olson, Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831,
       (615)574-7819
Objectives and Coverage:

       This database consists of estimates  of surface water characteristics by lake size class,
alkalinity class,  and wet  deposition levels  for H+,  SO4, and NO3  for  each of the 3.75-min
latitude/longitude cells in northeastern United States.  Alkalinity classes of surface waters in New
York and New England were estimated from a detailed northeast regional surface water alkalinity
map.  The map was digitized, and alkalinity classes were  assigned to  3.75-min latitude/longitude
cells. Estimates of the extent of surface waters were derived by estimating the percentage of lakes
in four size classes for  each  of the latitude/longitude cells.  Annual wet deposition values for
hydrogen,  sulfate, and nitrate ions were  estimated from monitoring data in  the Acid Deposition
System (ADS).   See separate  entries for ADS and for the  Acid  Deposition Data Network
(ADDNET).

       Detailed information was not available at the time of publication.

Objectives and Coverage:

       These data consist of ozone concentration levels by county and by a 0.5 by 0.5 degree
latitude/longitude grid across the continental United States. Both data sets contain estimates of 7-
hour average ozone concentrations for the time periods April to May, April to June, May to
September, June to September, and June to October for each year from 1978 to 1982 (except June
to October, 1982).  The gridded data values were estimated by extrapolating from  monitoring
stations selected to minimize urban influences. The extrapolation used a kriging  algorithm.  The
county values were estimated from  the  gridded data.   This same  data appears  in a more
comprehensive form in the Aerometric Information and Retrieval System (AIRS).  See separate
entries for AIRS and for the Acid Deposition Data Network (ADDNET).

Objectives and Coverage:

       The OPPE Food Residue database contains pesticide residue data on raw and processed
food. Data are provided on a voluntary basis by other government agencies and food processing
companies. Monitoring data for 286 pesticides on an estimated 49,857 samples taken predominantly
during 1985 to 1988 are included in the database (data through 1991 will be included by the end
of fiscal year 1991). These data are used to estimate pesticide residues in the general  food supply
for scientific and  regulatory  purposes by government agencies  (EPA, U.S. Food and Drug
Administration (FDA), and states). The food and pesticide industries, food industry trade groups,
and public interest groups also use this information for scientific and other purposes.

-------
Sample Design and Analysis:

       Monitoring information is obtained on  pesticide  residues present in  raw agricultural
commodities, animal products, and processed foodstuffs by the Pesticide Policy Branch from three
sources:  state monitoring data compiled by the FDA, the National Food Processors Association,
and Agriculture Canada. The format in which information is received is often inconsistent (e.g.,
commodities reported by different names, pesticides listed by different chemical names); therefore,
the data are edited to remove obvious errors and inconsistencies before they are entered into tables,
using the ORACLE Relational Database Management System.

       A draft report which includes methods to improve this program is presently being reviewed
by the U.S. Department of Agriculture (USDA) and the FDA.  The recommended methods to
improve  the  database include:  standard residue sampling protocols used by state and federal
agencies; a minimum set of information to be provided with each sample; and a standard data
coding system and database format for the transmission of data.

Contact Person: Anne Pilli, U.S. EPA, Environmental Research Lab, 6201 Congdon Boulevard,
       Duluth, MN 55804, (218) 720-5516
Objectives and Coverage:

       AQUIRE was  established to provide scientists and managers  with quick access  to  a
comprehensive, systematic, computerized compilation of aquatic toxicity data. The database consists
of aquatic toxicity data extracted from scientific papers from over 6,000 domestic and international
publications from 1970 to the present, and from independently compiled data files.  The scope of
the scientific papers included has been defined by the criteria of single chemical exposure and has
been limited to those organisms that are exclusively aquatic. Interactions on the aquatic interface
(amphibians,  bipeds,  mammals,  reptiles,  rooted  semi-aquatic plants),  and the microscopic
community (bacteria and viruses) are omitted. Exposures must either be aqueous, diet, or injection;
in vitro toxicity test results  are not included.  The database does not include exposures  from
petroleum-based mixtures, complex effluents, chemical mixtures, and water chemistry effects  (e.g.,
pH). Exposures are tested in fresh water, salt water, tap water, brackish water, or estuarine water.
Both field and lab tests are included.  Results are mostly relevant to surface  and  marine water
exposures. Acute, sublethal,  and bioconcentration effects are included for tests with freshwater and
marine organisms.  The 'data collected include over 100,000 individual test results and information
on 5,200 chemicals and 2,400 aquatic organisms.

       AQUIRE is designed to be used as a reference tool, with individual and summary aquatic
toxicity data catalogued by  toxicant, test organism,  test  conditions, and test  endpoint.  Tissue
residue and bioconcentration information for edible portions of aquatic species are stored in the
database. AQUIRE has potential for use in aquatic to human extrapolation of chemical exposures
and risks.  Because AQUIRE is a compilation of the available  data, it is recommended that
researchers requiring contextual information for the data consult original publications; reprints of
all references included in the database are on file. Additional information regarding purity, grade
formulation, active ingredients, and radiolabeled isotopes is stored in AQUIRE text files, which are
not available to the user at this time.

Summary of Environmental Data:

Media:  Aquatic food sources (e.g., fish, shellfish, algae)

Classes  of compounds:   Inorganic compounds, VOCs, semi-VOCs,  pesticides, PCBs,
       dioxms/fiirans, radionuclides

Type of data available:  Individual data entries and summary statistics are available on
       specific agents

Estimation versus observational data: All observational data

Sample Design and Analysis:

       Aquatic toxicity data published in United States and international scientific papers and data
from independently compiled data files are collected and reviewed  for appropriateness  for the
AQUIRE database. Toxicity papers are acquired by literature searches, review article bibliographic
listings, U.S. EPA Water Quality Criteria document bibliographies, and from existing toxicity reprint
collections.  The literature  covers  1970 to the present, with current publications acquired and
reviewed on a continuing basis. The bibliographic file and the main database files are checked for
duplicate  publications  to  assure that each data point is included only once in AQUIRE.   If a
publication contains data for a  single chemical,  in addition to one of the above categories of
toxicants,  the paper is retained and only the single chemical data are used in AQUIRE.

       If data are published in a dissertation,  symposium proceeding, internal report, or a book,
in addition to a peer-reviewed  journal, only  the journal publication  is included in AQUIRE.
Foreign publications are reviewed if either an English abstract or a translated table of data are
included.  Data reported in  review papers are  abstracted from the original publication.


                            DATABASE CHARACTERISTICS

Geographic Characteristics:

     Coverage: National and international

     Identifiers: No geographic identifiers (database consists primarily of laboratory test results);
              the data elements in AQUIRE are grouped by test chemical, test organism, test
              conditions, and test endpoint

Time Coverage: 1970-present

Sample Characteristics:

     Frequency of sample collection: Variable, depends on source of data (data obtained from the
              literature)
                                            1-22

-------
     Regularity of sample collection: Variable, depends on source of data (data obtained from the
              literature)

     Source information:  None available

     Dispersion information: Not applicable — no data collected at the source

Methods of Sample Analysis:  Data are collected from the literature

     Samples pooled: No

     Standard procedures used: The data encoded are evaluated according to existing standard test
              methods such as the American Society for Testing and Materials, U.S. EPA, and the
              American Public Health Association; each test reviewed for AQUIRE is assigned
              a review code that indicates the adequacy of method documentation available in the
              scientific paper

     Approximate time between sample collection and analysis:  Variable, depends on source of
              data  (data obtained from the literature)

     Approximate time  between sample analysis and data entry to database:  Data are obtained
              from the  literature, reviewed for quality, and entered into the database on  a
              quarterly basis

Quality Assurance/Quality Control Procedures:  Quality assurance procedures begin with
     literature acquisition and cataloging and continue through the chemical and species files,
     the literature review process, data entry, and data retrieval.  The AQUIRE literature is
     processed by reviewers who receive 4 months of training.  To be included in AQUIRE,
     a study must involve exclusively aquatic test organisms; involve toxicants having Chemical
     Abstracts Service Registry Numbers  (CASRNs);  involve aqueous, dietary, or  parental
     exposures;  test chemicals;  describe test conditions and  test endpoints;  and provide
     documentation of test methods that conform with  standard quality assurance guidelines.
     Based on these and other  criteria, studies are rated by AQUIRE reviewers  as:  (1)
     meeting all criteria, (2) generally satisfactory, (3) weak or unsatisfactory, (4) format
     limitation associated with an abstract or foreign paper, or (5) study in the  Gilford File.
     (The Gilford File, added in February 1989, contains laboratory data for Acute Toxicity
     of Organic  Chemicals (ATOC), determined using a single test species, 30-day fathead
     minnows.)   Data obtained from independently  compiled  data files must meet the
     AQUIRE data parameter and quality assurance guidelines.  If tests are missing key
     fields, or the experimental methodology was erratic, the data are rejected. Transfer of
     data is by computer with accompanying quality assurance procedures.

     Following the  extraction of acceptable data, a 10 percent quality assurance check of
     CASRN,  verification of species Latin name, and  confirmation of effect concentrations
     are made.  Differences (if any) are documented, discussed, and resolved by the data
     coordinator. Any subsequent corrections are also reviewed by two staff members. In
     addition to  manual checks, there are  various computerized checks within the database
     structure. A biannual EPA QA/QC audit is also conducted.

Objectives and Coverage:

       As required by the Resource Conservation and Recovery Act (RCRA), the Code of Federal
Regulations, Title 40 requires generators of hazardous wastes and facilities that treat, store, or
dispose of hazardous wastes to file biennial reports. EPA's OSWER maintains and publishes this
information every other year in National Biennial RCRA Hazardous Waste Reports.  These national
reports include national and state-level data and analyses on: the types and amounts of hazardous
wastes generated; waste treatment methods (e.g., injection well, landfill, incineration); and waste
management and waste minimization practices. The national biennial reports also include rankings
of types of hazardous wastes generated and amounts generated by states and facilities.  Imports and
exports of hazardous wastes for each state are also included, as is a comparison of the latest and
previous national data.  Summary profiles of the generation and management of hazardous wastes
for each state are provided.

       The comprehensiveness of the national biennial reports is limited by inconsistent  reporting
by states, although EPA has placed major emphasis on assuring the quality of submissions from the
largest hazardous waste generators and management facilities and is revising RCRA regulations to
require more consistent and comprehensive information.  The national biennial reports  do not
include data on wastes exempted from RCRA permitting requirements (e.g., wastewater treatment
tank units regulated under the Clean Water Act),  nor do they include data on RCRA-generated
wastes that are exported out of the United States.
Summary of Environmental Data:

Media: Water, soil, air, bulk chemicals

Classes  of compounds:   Hazardous waste codes as defined in 40 CFR,  Part  261, subpart D,
       including inorganic compounds; pesticides; VOCs; semi-VOCs; ignitable, corrosive, and
       reactive wastes

Type of data available:  National and state-level summary data are available

Estimation versus observational data: Both estimated and observational data
                                          1-25

-------
Sample Design and Analysis:

       Generators and managers of RCRA hazardous wastes submit site reports to EPA regional
offices or to state offices authorized by EPA to administer RCRA programs by March 1st of each
even-numbered year. The National Biennial RCRA Hazardous Waste Report is a compilation and
analysis of this information.  Due to inconsistent reporting by states, some data submitted to EPA
have provided detailed site-specific information, while other data have been reported only at the
aggregate level  (e.g., total  quantity of waste generated at a site,  but not the types of waste
generated).  Since these summary-level data were the only data that could be obtained for all sites,
only summary data were used to conduct national analyses in the 1987 National Biennial Report.
In addition, some states did not report all hazardous wastewaters subject to RCRA; these exclusions
may have resulted in artificially low state and national quantity totals.  Also, in some cases, EPA
could not unambiguously determine which generators were subject to  reporting under RCRA, thus
resulting in a possible underestimation of hazardous waste generators.  Finally, California did not
provide compatible waste characterization data for  most of its generators; again, this may have
resulted in an under-representation of generators in the EPA national  report.

       Quality assurance measures helped to resolve some of the data inconsistency problems
described above. Data were checked for completeness and internal  consistency.  In addition, an
evaluation of the largest  hazardous waste generators and management  facilities in each state was
conducted.  This involved sites  that generated or managed more than 100,000 tons of RCRA
hazardous wastes in 1985, 1986, or 1987, and also the 5 largest sites in each state  regardless of the
quantities they generated. Subsequent to these quality assurance measures, EPA prepared draft
profile reports for each state which were reviewed by the state's  environmental coordinator for
accuracy.  Data were then corrected for the National Biennial Report.

    CARBON MONOXIDE TOTAL EXPOSURE ASSESSMENT METHODOLOGY STUDY
Acronym:  CO TEAM
Sponsoring Agency:  U.S. Environmental Protection Agency (EPA), Office of Research and
       Development
Contact Person:  Gerald G. Akland, U.S. EPA, Office  of Research and Development, MD-75,
       Research Triangle Park, NC 27711, (919) 541-4885
Objectives and Coverage:

       CO TEAM was primarily designed to characterize population exposures to carbon monoxide
(CO) and to characterize the sources contributing to those exposures.  The data resulting from CO
TEAM were to serve as input to EPA's CO criteria document and subsequent Agency regulations.
The Total Exposure Assessment Methodology (TEAM) was used for measuring the frequency
distribution of carbon monoxide (CO) exposure in a representative sample of an urban population.
(See also the Volatile Organic Compound Total Exposure Assessment Methodology Study (VOC
TEAM), the Particle Total Exposure Methodology Study (PTEAM),  and the Nonoccupational
Pesticide Exposure Study (NOPES) in this Inventory.)  A CO personal exposure monitor (PEM)
was developed and the sampling methodology was tested.  The methodology was applied in two
urban areas, Washington, DC, and Denver, Colorado, during the winter of 1982-1983 (the time of
year when maximum fixed-site CO levels usually occur). Personal exposure monitoring data were
collected together with activity data from a stratified probability sample of residents living in each
of the two urban areas.  Well-established survey  sampling procedures were used for selecting
individuals.  The resulting exposure data permit estimates  of CO  exposure for the  eligible
populations of the two areas, as well as statistical comparisons between population subgroups (e.g.,
commuters vs. noncommuters and residents with and without gas stoves).
Summary of Environmental Data

-------
Sample Design and Analysis:

       The methodology was developed and tested to estimate the distribution of personal, hourly
exposures to CO and the distributions of personal exposures associated with various activities and
environments. A nine-person pilot study was conducted in Los Angeles in 1980.  The personal CO
monitoring methodology was then field-tested in two target areas, Denver, CO, and Washington,
DC, during  the winter of 1982-1983.   The target  population in each city consisted of
noninstitutionalized, nonsmoking adults who were 18 to 70 years of age.

       A stratified, three-stage, probability-based sampling procedure was employed  in each city.
During the first stage, the geographic area was divided according to Bureau of Census standardized
areas and a sample of these areas was selected.  A compiled list of address  and telephone numbers
were used as  the sampling  frame  for selecting households  during  the  second stage..  A
knowledgeable  household member was given a short screening interview to obtain  information
about  each household member.  The household  screening data were used to identity eligible
individuals (i.e., non-smokers, aged 18 to 70) so that they could be targeted for oversampling in the
third stage. The individuals in the third stage sample were asked to carry  a personal  CO monitor
and fill out an  activity diary for a  24-hour period.  Each individual was monitored  for 1 day in
Washington and 2 days in Denver. The PEM recorded the time  and  average CO concentration
each time the  "activity button" on top of the instrument was  pushed, and the average CO
concentration every hour.   In both cases,  the CO value  was the integrated  average CO
concentration since the last recorded value.  The participants also wrote down the time, location,
and activity code in the diary every time they pushed the activity button on the instrument. Each
participant carried a new PEM and diary for a second, consecutive, 24-hour period in Denver.

       The study included measurements of CO  in exhaled breath for every  participant.  The
purposes of the breath measurements were to estimate the distribution of carboxyhemoglobin
(COHb) values in the two  populations using accepted relationships  between  alveolar CO and
COHb; and to compare the observed breath measurements with personal exposures.  Breath CO
concentrations of 625 nonsmoking persons in Washington, DC and 454 nonsmokers in Denver, CO
were collected in the winter of 1982-83.

       Household  screening  questionnaire data were collected  from 4,408  households in
Washington,  DC and 2,133 households in the Denver metropolitan area.   In Washington and
Denver,  1,161  and 485 subjects, respectively,  agreed to participate.  The CO TEAM study,
performed between November 1982  and February 1983, produced 712 and 808 valid  complete
person-days of data in Washington and Denver, respectively.  The fraction  of selected nonsmoking
adult individuals who agreed to participate was 58 percent in Washington and 43 percent in Denver.
Although these response rates are not high, they are consistent with the response rates of similar
TEAM studies  in which personal monitoring was conducted.

       260-3507
Objectives and Coverage:

       Under the Toxic Substances Control Act (TSCA), Section 8(e), notices of substantial risk
are submitted to the Chemical Screening Branch (CSB) of the U.S. EPA Office of Toxic Substances
by manufacturers, processors, distributors, and importers of chemicals when they become aware of
new data that supports a conclusion that a chemical may present a substantial risk of injury to
human health or the environment.  In addition, For Your Information (FYI) submissions are also
submitted, which are similar in content to the TSCA Section 8(e) notices, but are voluntary and go
beyond statutory requirements under TSCA.

       CECATS tracks documents submitted to and developed by the CSB and contains both
administrative and chemical hazard/exposure tracking information. The purpose of CECATS is to
help determine which substances need further regulatory review.  Chemical Hazard Information
Profiles (CHIPs) or Substitute Hazard Profiles are written for substances of greatest concern based
on environmental and health effects. Administrative tracking information includes submission and
report dates, submitter names, status of review, and initial disposition or distribution to outside
groups.  Examples of chemical hazard/exposure information include Chemical Abstracts Service
Registry Number (CASRN), chemical name, and information type (type of toxicity or exposure data
contained in the document). CECATS is a document-tracking system, not a chemical-tracking
system, but it does track which chemicals are in which documents.  Similarly, CECATS does not
contain endpoint information (such as actual toxicity values or toxicity information), but does track
which kinds  of information can be found in which documents.

Summary of Environmental Data:

Media: Water, soil, air, human food sources, human samples, bulk chemicals

Classes of compounds: Most hazardous or toxic chemicals, including: VOCs, semi-VOCs, PCBs,
      inorganic compounds, pesticides

Type of data available:  Qualitative analyses of documents discussing particular chemicals; no
      individual samples referenced

Estimation versus observational data: Both estimated and observational data are contained in the
       documents referenced

Sample Design and Analysis:

       Each time a TSCA Section 8(e) notice or FYI submission is received by the Chemical
Screening Branch, a screening process  is initiated  to  determine whether a Chemical  Hazard
Information Profile (CHIP) will be developed for that substance.  CHIPs are brief narrative reports
(20-40 pages) that summarize the readily available information on health effects, environmental
effects and exposure relating to a specific chemical. Substitute Hazard Profiles are also developed,.
which are similar in content to CHIPs but generally are less comprehensive and shorter (10 pages),
address only  one type of toxic effect,  and-do not  address exposure.  During screening, CSB
considers factors  such as TSCA  jurisdiction, severity  of toxic effect, extent  of exposure and
assessment, and regulatory status. Nearly 98% of all chemicals screened are not selected for further
review and are not published as CHIPs or Substitute Hazard Profiles.

       541-2291
Objectives and Coverage:

       CHAMP consists of epidemiological studies conducted in large metropolitan areas of the
United States to determine human health effects and morbidity and mortality associated with air
quality in these areas.  Pollutant sampling data include long- and short-term air monitoring for
particulates, criteria pollutants,  benzopyrene, and selected inorganic compounds.   In  addition,
human tissue samples from autopsied cadavers; and pulmonary function testing of individuals from
these areas were collected.  Also included are results from a separate study which compared air
samples collected in a small town with those collected in a large city in California; and results of
pulmonary function tests of individuals who spent time in both of these areas.

       This program was implemented during 1972-1977 by the former Epidemiology and Biometry
branches of the EPA.
Summary of Environmental Data:

Media:  Air, human samples

Classes  of compounds:   Particulates,  criteria  pollutants, inorganic  compounds,  semi-VOCs
       (benzopyrene)

Type of data available:  Individual data entries are available on specific agents

Estimation versus observational data:  All observational data
                                          1-37

 Sample Design and Analysis:

       Los Angeles, CA; Birmingham, AL; Salt Lake City, UT; Charlotte, NC; and Riverhead, NY
 counties were selected by scientists at EPAs Epidemiology and Biometry Branches to be included
 in a long term study of health effects of pollution. These study areas were selected because they
 represent large metropolitan areas with an increase of respiratory disease caused or aggravated by
 air quality.  Local health officials in these  counties were consulted to help select air monitoring
 locations according to zip code.  Continuous analyzers, located in areas in the center of selected
 zip codes,  measured criteria pollutants, benzopyrene, and  selected inorganic  compounds 24-
 hours/day,  365 days/year.  At the same  time, size-selective particulate samples were collected on
 filters using high volume samplers. Visibility monitors were also located in counties known to have
 especially poor air quality. In addition, short term air quality sampling was conducted at facilities
 in these areas where episodes affecting human health were reported in the Morbidity and Mortality
 Weekly Report (Centers for Disease Control, Department of Health and Human. Services).   If
 pollutant concentrations were found to  be  elevated,  operation at the facility was halted by EPA
 until air  sample results were found to be within acceptable levels.

       As part of this study, EPA contracted with the University of California (at Riverside) for
 pulmonary function testing and medical examinations to  be conducted on individuals residing in
 these geographic  areas. Volunteers were obtained through a screening questionnaire; testing and
 examinations were conducted in portable vans located in  each of the areas.

       EPA  also contracted with the University of California for human tissue (hair and fat)
 sampling of autopsied cadavers from medical facilities in these  areas.  Pathologists  contacted
 researchers at the University whenever an autopsy was performed on individuals who had resided
 in these areas. Samples were frozen, collected, and analyzed  for various trace elements.

       Samples of maternal and  fetal blood and hair were also collected immediately  following
 delivery  by physicians  of hospitals  within  the  geographic  areas in cooperation  with EPAs
Epidemiology and Biometry branches. These samples were sent to an EPA contracted laboratory
for analysis of trace elements.

       A separate study compared air quality sample and pulmonary function.test results collected
in a small town with those collected in a large city in California. Ambient air samples for criteria
pollutants, particulates, benzopyrene, and selected inorganic compounds were collected  at Pacific
College,  Anjun, CA,  located in the  mountains of Napa  Valley.  At the same time, pulmonary
function  tests were  conducted on students  who volunteered for this study and were planning to
attend medical school at the affiliate Loma Linda University in LaSierra, CA. Once at Loma Linda
University,  the pulmonary  function  of these students  was re-tested  and similar  air quality
measurements were collected.

Objectives and Coverage:

       CDS provided source data for the AIRS Facility Subsystem (AFS) and has been replaced
by the AFS (see separate entry for AFS).  CDS was the standard mechanism for compliance and
enforcement tracking for all federal air emissions enforcement agencies and for over half of all state
and local enforcement agencies, especially for requirements such as  State Implementation Plans
(SIPs), New Source  Performance Standards  (NSPS), and National  Emissions Standards for
Hazardous Pollutants  (NESHAPs). CDS information included data on all major and many minor
stationary sources of air pollution and included: an inventory of facilities subject to local, state, and
federal emissions regulations; descriptive  facility information; type  of pollutant being emitted;
emission point-information1 (e.g., process  description); compliance tracking of violators  and of
facilities in compliance; and data on compliance and enforcement actions and progress, such as
inspections, enforcement schedules, notices of violation, civil actions, criminal actions, and orders.
CDS assisted local, state, and regionaljegulatory agencies in developing enforcement strategies and
providing reports that fulfilled performance  and reporting  requirements.   CDS users were
responsible for data submissions, quality control, and retrieval,  and  were encouraged to closely
follow CDS quality assurance procedures.

       CDS included data for over 70,000 stationary sources, with complete information for Class
A sources (as  defined by the 1980  Alabama Power Decision)  and less complete information for
Class B  sources.  Information was complete  for  violators and less complete  for facilities  in
compliance. Over 12,000 enforcement actions were included.  Different emission points within a
single facility could be assessed, as well as total potential uncontrolled emissions for each process.
Pollutant loading information was available for a limited number of facilities through CDS (more
complete data sources were NEDS and  AIRS).  In addition to known point sources, which are
required to be tracked,  CDS  included  information on  unverified  Class A VOC  sources
(approximately 4,000 sources). Local, state, and regional enforcement offices also entered other,
nonmandatory types of data and information about other facilities into  CDS.  Data on  special
enforcement problem  areas were also included in CDS, such as information on selected primary
copper, lead, and zinc smelters (e.g., emission and process point identification).

       Detailed information was not available at the time of publication.

Objectives and Coverage:

       The  Eastern Lake Survey was conducted in two phases as part of the National Surface
Water Survey (NSWS; other components included the Western Lake Survey and the National
Stream Survey, also described in this Inventory). Through a two-phase monitoring program, the
ELS assessed the effects of acidic deposition on surface waters in the Northeastern United States,
upper Midwest, the southern Blue Ridge,  and Florida.  The objectives of the Phase I survey
conducted in the fall of 1984 were to  determine  in potentially sensitive regions of the eastern
United States: 1) the percentage  and location of lakes that were acidic (based on  fall samples); 2)
the percentage and location of lakes that had low acid neutralizing  capacity (ANC); and 3) the
chemical characteristics of the lakes studied.  Another objective of Phase I was to provide a
database for selecting lakes for further study.

       The  objective of ELS-Phase II, conducted in 1986, was  to assess temporal variability in
regional lake water chemistry with respect to acidic deposition effects. To achieve this, the ELS-
Phase II: 1) assessed the sampling  error associated with ELS-Phase I sample; 2)  estimated the
number of lakes that were not acidic in the fall, but were acidic in other seasons; and 3) established
seasonal water chemistry characteristics among lakes and related the fall index sample to seasonal
and annual water chemistry patterns.
Summary of Environmental Data:

Media:  Surface water (lakes)

Classes  of compounds:  Inorganic compounds, ions (including fluoride), physical and chemical
       indicators of water quality

Type of data available:  Individual data entries and summary statistics are available on specific
       agents

Estimation versus observational data: All observational data
                                          1-43

-------
Sample Design and Analysis:

       For ELS-Phase I, water samples were collected in the fall of 1984 from 1,612 lakes selected
from within three regions of the eastern United States (Northeast, Upper Midwest, and Southeast)
expected to exhibit low buffering capacity (measured by ANC).  A number of chemical variables
and physical attributes thought to influence or be influenced by surface water acidification were
measured for each lake. Lakes were selected by a systematic random process. The sample design
allowed the ELS-Phase I database to be used to investigate the chemical status of lakes within a
specific region.  Additionally, the database can be used to investigate correlative relationships
among chemical variables on a regional basis.

       For ELS-Phase II, water samples were collected from 145 statistically representative lakes
only from the Northeast in three seasons  (spring, summer, and fall of 1986).  Lakes analyzed in
ELS-Phase II were chosen from those samples in ELS-Phase I, using a variable probability sample,
and results were compared to the ELS-Phase I results.  Like ELS-Phase I, data from ELS-Phase
II can be used to provide unbiased estimates of the status and extent of acidic and low ANC lakes
for a defined lake population.  However, the ELS-Phase II sample did not include lakes with the
following characteristics:  lakes with  high ANC (>400  ug/L); severely nutrient-enriched lakes;
shallow lakes  (<1.5  m deep);  large  lakes (>20  km2); and lakes  modified by anthropogenic
disturbances (e.g, major wastewater treatment plant discharge).

       In the Phase-II survey, data quality control measures identified several problems that would
limit the use of some sample results.  For  chloride, values measured at one of the labs should not
be used; these suspect values are flagged in the database or labeled as missing.  Population
estimates for chloride should not be made for the summer and spring (fall values were measured
elsewhere and are valid). For conductivity  samples,  all field measurements appear to be unreliable,
were not validated, and should be interpreted with caution; no problems appeared with laboratory
conductivity measurements. For total aluminum, data showed very poor agreement between labs,
and precision was highly variable.   (This problem was evident in all NSWS surveys.)  Also, a
number of total aluminum values were less than one subcategory of aluminum. No measurement
problems were found with subcategories of aluminum. Finally, air-equilibrated dissolved inorganic
carbon and air-equilibrated pH showed some laboratory bias and poor precision at higher pH.
Users  are  strongly  advised to use  the closed-system  dissolved  inorganic  carbon  and pH
measurements for data analysis.

Objectives and Coverage:

       The Six Cities Study was an extensive multi-year epidemiologic investigation of exposures
and community health in six U.S. cities: Watertown, MA; Kingston/Harriman, TN; St. Louis, MO;
Steubenville, OH; Portage, WI; andTopeka, KS. The investigation consisted of ambient and indoor
air monitoring of selected pollutants in these  cities and health questionnaires and pulmonary
function tests  administered  to selected participants from the cities.  Ambient air measurements
included sulfur dioxide  (SO2), nitrogen dioxide (NO2), oxygen (O2), total suspended particulate
(TSP), and particulate matter less than  10/im in aerodynamic diameter (PM10) collected from a
central  site in each community for the purpose of assessing chronic and acute exposures of
epidemiologic study participants.  Concentrations, of NO2 and particulate matter less than 2.5/mi
in aerodynamic diameter  (PM^) were  measured in homes  of approximately  1,800 children
participating in the epidemiology study. Health  questionnaires and pulmonary function tests were
administered to a large cohort of children and adults from the selected communities between 1974
and 1989.  The objectives of this epidemiologic study were to study the: 1) chronic effects of air
pollution in longitudinal health data from the original cohort of children; 2) acute effects of air
pollution on pulmonary function as measured in  annual exams of children; 3) chronic effects of air
pollution on lung function in adults; 4) effects of air pollution in a repeated cross-sectional study
of children; 5)  effects of indoor air pollution on respiratory symptoms and lung function of children;
and 6) acute effects of air pollution on daily symptom reporting.

Sample Design and Analysis:

       The six cities (Watertown, MA, Kingston/Harriman, TN; St. Louis, MO; Steubenville, OH;
Portage, WI; Topeka, KS) were chosen to represent the range of sulfur oxide and particulate air
pollution in the United States from 1974-1977 and to ensure a geographic distribution  of the
samples collected. Adults between 25 and 74 years of age were randomly selected from various
census lists such as household voting lists or commercial listings. Because  the sampling frames in
the 6 cities were constructed at different times and in different ways, the initial samples varied from
2,174 to 3,583 adults.  The children initially selected included all first-  and second-grade  school
children in each community. In the Portage, WI area, the numbers were small, so children from
grades 1 through 4 were selected. This resulted in a different age distribution for this one city, but
all comparisons between cities were age-adjusted.  In Topeka, KS, more than half of the schools
were selected at random because of their size. All school children were evaluated annually. During
the first and second evaluations, new first-grade school children were added to the study if the
number of children in that community was less than 1,500. In each community, the school children
were first seen at the same time as the adults. The rate of refusal (i.e., refusal of the parents  to
allow their children to participate) did not exceed 5 percent in any school.

       The assessment of health effects in adults was made by personal interviews using a standard
questionnaire and simple  tests of pulmonary  function by trained nonmedical interviewers. The
questionnaire included  questions  on  respiratory symptoms,  tobacco  smoking  habits,  and
occupational and residential history.  It was a modified version of the British Medical Research
Council Questionnaire, which has been used for 15 years in population studies in the United States
and Canada.

       Air quality  monitoring was performed in each  community  in, an attempt to quantify
individual exposures to SO2, mass respirable particles, sulfates, NO2, and ozone.  This included
continuous  fixed-location  sampling,  indoor/outdoor  monitoring,   and  personal  monitoring.
Continuous monitoring equipment in each community was located at a central site representative
of the total residential exposure. From these primary sites, the hourly average concentrations  of
SO;,, NOj, and O3 were recorded.  In  addition, meteorologjc parameters (e.g., wind speed and
direction, temperature, and dew point), were recorded; and 24-hour integrated samples for TSP,
RSP, NOa, and SO2 were collected every 3 days at the central station. In 1979, new ambient air
monitoring was initiated including dichotomous sampling (PM^s and PM15) and elemental particle
composition analysis.

       The original cohort of children (1974-1989) consisted of 14,357 children who provided health
questionnaires and pulmonary function test data on an annual basis for 12 years. A new cohort of
6,273 children, similar in characteristics to the main cohort, provided 3 annual questionnaires and
2  pulmonary  function examinations between 1983-1986.  A stratified  sample  of homes and
approximately 1,800 children were selected from the second cohort of 6,273 for indoor air sampling,
based on smoking and use of a gas stove  in the home.  Daily respiratory symptom diaries were
obtained from these children for approximately 1 year. Indoor air monitoring included measuring
NO2 and PM^ concentrations  in homes.  In 1984, aerosol acidity measurements were begun.

       Response (OSWER),  OERR, Emergency Response  Division (ERD), (OS-210), 401 M
       Street SW, Washington, DC 20460, (202) 260-2342
 Objectives and Coverage:

       ERNS is a national database used to store information on releases of oil and hazardous
 substances.   The Comprehensive Environmental Response,  Compensation,  and Liability  Act
 (CERCIA), the Superfund Amendments and Reauthorization Act (SARA), the Clean Water Act
 (CWA), and the Hazardous Material Transportation Act require reporting of releases of oil and
 hazardous substances.   The  primary  purpose of ERNS is  to standardize  and collect these
 notifications made to the federal government. Since its inception in 1986, ERNS has received over
 170,000 release notifications.

       The ERNS program is a cooperative data sharing effort among EPA Headquarters, DOT
 Research and Special Programs Administration's John A. Volpe National Transportation Systems
 Center (VNTSC), and the National Response  Center (NRC) (a nationwide response center for
 chemical emergencies, staffed by the U.S. Coast Guard and sponsored by 14 federal agencies). EPA
 manages and funds ERNS, and the VNTSC provides operation and maintenance support through
 an interagency agreement with EPA.

        Currently, ERNS data are used to assist decision-makers in emergency  response  and
 release prevention issues.  Specific examples of ERNS data applications include  guidance  and
 regulatory development, responses to congressional inquiries, response preparedness, compliance
 and enforcement support, statistical and trend  analysis,  environmental planning, spill prevention
 programs, legal analyses, property transfers/site audits, and academic research.

 Summary  of Environmental Data:

Media:  Water, soil or sediment, air

 Classes of compounds:  Inorganic compounds, VOCs, trihalomethanes, semi-VOCs, pesticides,
       PCBs,  dioxins/furans,  radionucUdes, acids/acid aerosols,  criteria pollutants,  and  any
       other chemicals reported to ERNS as a  release

Types of data available: Individual data entries and summary statistics
                                         1-52

-------
Estimation versus observational data:  All observational data

Sample Design and Analysis:

       NRC, EPA Regions, and the U.S. Coast Guard generally receive the initial notification of
an oil or hazardous substance release.  A series of questions about the release are asked.  The
information is immediately transmitted to the appropriate EPA Regional Office or Coast Guard
District Office,  depending on the release  location.  The EPA or Coast  Guard  On-Scene
Coordinator (OSC) then transmits the information to the appropriate state and local response
authorities and other parties,  as necessary.  Information on all releases reported to the NRC and
EPA Regional Offices is electronically transmitted to the VNTSC in Cambridge, Massachusetts,
where it becomes part of the ERNS database.  Each EPA Region maintains its own Region-specific
database, which is a subset of the national database. Until 1989, information on releases reported
to the Coast Guard was provided to ERNS via the Marine Safety Information System. Since 1989,
many releases which would have been reported to the Coast Guard in the past are now reported
to the NRC.

       Examples of notification information in ERNS include discharger identification, date of
release, material released, cause of release,  damage/injuries/deaths,  amount released, source of
release, incident location, response actions taken, authorities notified, and environmental medium
into which the release occurred. Most of this information is obtained from the initial notification;
it is cited as  unverified data, because it may be incomplete or inaccurate.  Depending  on the
severity of the release  and response actions taken, the EPA or Coast Guard OSC may obtain
further information from personnel at the release site or through discussing of the situation with
state and local officials.  In instances where notification information is verified, additional and more
detailed data on the release, including, information 'related to response actions, can be added to
ERNS.  Although field samples may be collected by emergency response personnel, sampling data
are not included in ERNS.

       Road, Ann Arbor, MI 48105, (313) 668-4200
Objectives and Coverage:

       The  Emissions  Certification Database contains emissions data on  regulated pollutants
(hydrocarbons, carbon  monoxide, and oxides of nitrogen) from certain types of motor vehicles
(automobiles and small trucks). Measurements are based on exhaust gases measured at the tailpipe.
The measurements  are taken by the U.S.  EPA's Office of Mobile Sources,  and the vehicles
represent all new domestic and imported consumer vehicles introduced into the United States
nationally.  Test vehicles are selected based on the likelihood of being worst-case emitters.  Each
type of engine is tested once per year. The Emission Certification  Database verifies emissions
information supplied by manufacturers and is required under the Clean Air Act. The information
is primarily used by the U.S. EPA and manufacturers for regulatory purposes to ensure emission
compliance. Some analytical results are confidential.
Summary of Environmental Data:

Media:  Air (automobile exhaust emissions)

Classes  of compounds: Particulates (hydrocarbons), criteria pollutants (CO, NOJ

Type of data available: Individual samples and summary statistics are available on specific agents

Estimation versus observational data: All observational data
                                          1-56

-------
Sample Design and Analysis:

       All vehicles introduced into the United States each year  are required to comply with
emission standards under the Clean Air Act. Each engine family produced by a given manufacturer
is tested for the regulated pollutants based on emissions measured  at the exhaust pipe. Vehicles
are tested over a fixed cycle (speed-time or hp-time  tract), and results  are  calculated on a
grams/mile or grams/BHp-Hr (BHp-Hr=break horse power per hour, a measure of the output of
an engine) basis. Testing procedures are developed by the Society of Automobile Engineers (SAE).

Objectives and Coverage:

       In 1988, the Science Advisory Board of the U.S. EPA recommended implementing a
program within EPA to monitor the  status and trends of ecological conditions and to develop
innovative methods for anticipating emerging problems before they become crises.  In response,
EPA initiated EMAP.    The  first five years of the  Program will involve the design  and
implementation of the system. EMAP objectives include: estimation of the current status, changes,
and trends in indicators of the condition of the nation's ecological resources on a regional basis;
monitoring of indicators of pollutant exposure and habitat condition; identification of associations
between human-induced stresses and  ecological condition; and generation of periodic statistical
summaries and interpretive reports on status and trends to resource managers and the public.  The
EMAP networks will provide statistically unbiased estimates with quantifiable confidence limits over
regional and national scales  for periods of years to decades.

       Six broad ecological  resource categories have been defined within EMAP:  near-coastal
waters, inland surface waters, wetlands,  forests, arid lands, and agroecosystems.  Within each of
these categories, EMAP is determining the ecological resource categories  and resource sampling
units that will be assessed in a series of annual surveys. Indicators of response, exposure, habitat,
and stressors will be defined. These will determine the types of environmental assessments that will
be  conducted, such as  biomarkers,  pathogens, bioassays,  tissue  concentrations,  ambient
concentrations, exotics, habitat structure and landscape pattern.

       In 1990, EMAP initiated its first demonstration project,  a study of estuaries in the mid-
Atlantic  region.   These  data  will be  used for analyses  to determine indices.   Additional
demonstration  projects will  be  conducted over the next several years.  Full implementation of
monitoring in  all resources is being targeted for 1995.

Summary of Environmental  Data:

Type of data available:  Individual samples and summary statistics are available on specific agents

Estimation versus observational data:  All observational data

Sample Design and Analysis:

       The probability-based EMAP sampling design will lead to unbiased estimates with known
confidence of the extent of resource classes and their current ecological condition. The proposed
sampling design uses a systematic triangular sampling grid of randomly placed points in the U.S.
Grid density will vary to meet specific needs, but the baseline density will be one point per 640 km2
(about 12,600 points in the contiguous United States, around 2,400 points in Alaska, and 56 points
in Hawaii).  A two-stage process is then used to  select points from the grid for landscape
description  and sampling site selection.   In  the first stage, landscape within a hexagonal area
centered on a  subset of grid points  sampled probabilistically  from the large  grid will be
characterized to estimate the extent of each resource class and to aid selection of resource sampling
units. In the second stage, a subset of resource sampling units is selected for each resource class,
from which  regional estimates are to be made.

       EMAP will operate  a series  of annual surveys, measuring  indicators during a particular
season or other time period that is likely to be specific to each resource category.  Distinct subsets
of sampling points (resource sampling units) will be selected, and environmental assessments will
be performed on a rotating four-year cycle. A particular site will therefore be sampled only every
fourth year, and condition estimates  will be based on four-year running averages.  Consequently,
EMAP will provide sufficient information about the conditions at any particular site for a period
of 40 to 60 years.  Standardized analysis procedures will be developed for each survey and study
component.

            ENVIRONMENTAL RADIATION AMBIENT MONITORING SYSTEM
 Acronym:  ERAMS
 Sponsoring Agency:  U.S. Environmental Protection Agency (EPA), Office of Radiation Programs
 Contact Person:  Geraldine A. Luster or Paula Goode, U.S EPA, Office of Radiation Programs,
       National Air and Radiation Environmental Laboratory, 1504 Avenue A, Montgomery, AL
       36115-2601, (205) 270-3433
 Objectives and Coverage:

       ERAMS is comprised of nationwide sampling stations that provide air, surface water,
 drinking water, and milk samples from which environmental radiation levels are derived.  The
 objective is to monitor and identify trends in the accumulation of long-lived radionuclides in these
 media.  The surface water and drinking water data are compared with standards  set forth in the
 U.S. EPA National Interim Primary Drinking Water Regulations (NDPDWR).  The milk program
 is a cooperative effort with the Food and Drug Administration.

       The field sampling stations are selected for wide population coverage as well as being
 located near possible sources of environmental radioactivity, including nuclear power plants and
 related industries.  However, data may be too sparse for use in human health studies.
Summary of Environmental Data:

Media: Water (including surface water, drinking water, and precipitation); air; food sources (milk)

Classes of compounds:  Radionuclides; particulates (gross beta radiation); radiation (alpha, beta,
       gamma)

Type of data available:  Individual data entries are available on specific agents

Estimation versus observational data:  All observational data
                                          1-63

-------
Sample Design and Analysis:

       Since 1973, environmental radiation monitoring has been conducted for airborne participates
and precipitation, drinking water, surface water, and pasteurized milk (at milk processing facilities).
Gross  beta radioactivity  measurements and certain  specific  analyses  are  performed  on air
particulates and precipitation samples as indicator measurements in assessing the general impact
of all contributing sources on environmental levels of radiation.

       Airborne particulates and precipitation  samples are collected continuously at 74 field
stations located throughout the United States near present and potential sources of environmental
radioactivity. Seventy-eight drinking water monitoring sites are located in areas near nuclear power
plants and related industries, preferably in major population centers, and 58 surface water stations
are located downstream from operating nuclear facilities. In a cooperative program with the U.S.
Food and Drug Administration's Dairy andLipid Product Branch, Milk Sanitation Section, monthly
milk samples are collected at 65 pasteurized milk processing facility sampling sites, with one or
more sites located in each state, Puerto Rico, and the Panama Canal Zone.

       Sample collection for all media is conducted by state health departments (on a goodwill
basis).   After  collection,  samples are sent to the National Air and Radiation Environmental
Laboratory (NAREL) for analysis. Samples are collected and analyzed using standard procedures
from the EPA "Radiochemical Procedures Manual."

                     major milk suppliers representing more than 80% of milk consumed in a
                     given population center. Monthly samples are analyzed for gamma emitting
                     nuclides; quarterly composites are analyzed for strontium.  For the first
                     month of the 3 quarters beginning January, April and October, 10 regional
                     composite samples of milk from states within each of EPA's 10 regions are
                     analyzed for strontium-89 and strontium-90; also,  all samples collected in
                     July are analyzed for strontium-89 and strontium-90

              If any samples in any of the media show increased concentrations above background

Objectives and Coverage:

       FRDS is a centralized database for information on public drinking water supplies, including
their compliance with monitoring requirements, maximum contaminant levels (MCL), and other
requirements of the Safe Drinking Water Act (SDWA) Amendments of 1986. Data are used for
the Public Water System Supervision (PWSS) Program maintained by EPA's Office of Drinking
Water.   ERDS  contains  approximately  12 million records.   Information tracked includes:
owner/operator name and address; operational status; location; on-site visits; sources; violations;
enforcement  and compliance actions;  treatment; variances and exemptions; area (county  and
population) the system serves; and historical information. Additional information is entered at each
state's  discretion.  ERDS does not track private wells or public water supplies  excluded by the
SDWA.
Summary of Environmental Data:

Media:  Surface water and ground water

Classes  of compounds:  Inorganic compounds, VOCs, semi-VOCS, trihalomethanes,  pesticides,

-------
Sample Design and Analysis:

       The Safe Drinking Water Act Amendments of 1986 stipulate that all public water supply
facilities must conduct monitoring, maintain records, and provide compliance and enforcement
information to EPA.  Monitoring must be performed in accordance with 40 CFR Part 141:  The
National Primary Drinking Water Regulations and analysis must be done in accordance with 40 CFR
Part 136: Guidelines Establishing Test Procedures for the Analysis of Pollutants. Public water supply
owners and operators are required to report monitoring results to the state (to the EPA Regional
office in non-primacy states or Indian lands) at frequencies (daily, monthly, quarterly, or yearly,
depending upon the contaminant) specified in state and federal regulations. Monitoring reports
are submitted to state  (or Regional)  enforcement officials, who determine if a  violation has
occurred and submit quarterly reports to EPA Headquarters containing any new information for
FRDS. Some states submit FRDS information  manually, while others have developed automated
data processing systems compatible with FRDS.

       The FIN database contains data and information relating to the distribution and status of
fish populations in surface waters in the Adirondack region of New York state that are sensitive
to or already  affected by acidic deposition.  All available  data on physical characteristics,  fish
populations, fisheries management  procedures,  and water  chemistry for 2,759 lakes  in  the
Adirondack Ecological Zone and approximately 600 other lakes in proximity to the Adirondacks
have been incorporated into FIN. Efforts to compile data for other  regions in the Northeast have
been initiated. Most data were obtained from 2 major sources:  the New York State Department
of Environmental Conservation (NYSDEC) and Carl L. Schofield of Cornell University. Additional
water chemistry data were obtained from Donald F. Charles of Indiana University. Data compiled
in FIN have been recorded at the most specific level of detail possible.  Also see separate entry for
the Acid Deposition Data Network (ADDNET),  which maintains  14 data sets that contain
information on lake morphometry, station location, fish status, and water chemistry.

       Detailed information was not available at the time of publication.

 Objectives and Coverage:

        The Fluoridation  Census was first collected from states in 1967. The census has been
 conducted on a periodic basis, with the most recent census being the 1989 census. The purpose of
 the census  is to determine the proportion of the population that is receiving the benefits of
 optimally adjusted fluoridated  water and  to  monitor this  proportion over time.   Further,
 information from this census helps target prevention programs administered  by NCPS.

        The NCPS maintains  a master file of water systems that have reported fluoridation in the
 previous census.  When the census is updated, these lists are sent to the states.  The states are
 requested to update both  the status of fluoridation of the water system and the population served
 by the water system.
 Summary of Environmental Data:

 Media: Water (drinking water)

 Classes of compounds:  Ions (fluoride)

 Type of data available:  Individual data entries

Sample Design and Analysis:

       The Fluoridation Census is intended to be. a complete enumeration of public water supplies
that contain fluoride, either through natural sources or through chemical additives.  The NCPS
maintains a master file of water systems that have reported optimum fluoridation in the previous
census.  Optimum levels  are determined by the state and are given in the database.  When the
census is updated, the master list is sent to the states. The states are requested to update both the
status of fluoridation of the water system and the population served by the water system.  Only
public water supplies are included in this census. Further, only the public water supplies that are
optimally fluoridated are listed in the census.  Water supplies are classified as community, military,
native American, or school water supplies.

       Geographic information is given for the site of the treatment facilities, but not for the extent
of the distribution of the water system. There are water systems that cross county boarders, but
the extent of the population served in each county are not given.
       Analyses of fluoridation are conducted in accordance to EPA regulations.

Objectives and Coverage:

       GEMS, established under the auspices of the WHO, UNEP, and the FAO, is a program
which involves monitoring of air, water, and food quality on a global scale.  Scientists from 60
countries throughout the world participate in GEMS.  GEMS/AIR contains results of air quality
sampling; GEMS/WATER includes freshwater quality sample results; and GEMS/FOOD contains
food contamination results. Although the three programs do not cover many of the areas in the
developing world, they do provide valuable information which indicates current regional, national,
and global trends in environmental health.

       The Collaborating Center on Air Pollution Control, established by the WHO and operated
by the U.S. EPA, maintains the GEMS/AIR database on EPA computers using application systems
designed specifically for the WHO. The WHO CCIW in Canada was established for the purpose
of data handling for the GEMS/WATER database. The GEMS/FOOD database is maintained by
the Information Systems Support Division at the  United Nations (UN) International Computing
Center, WHO headquarters in Geneva, Switzerland.

       Data for each of the GEMS monitoring programs are summarized and assessed by scientists
at the GEMS data centers, WHO, UNEP, and FAO (GEMS/FOOD data only). A series of air
quality, water, and food assessment reports are issued, such as, air quality assessment reports which
evaluate the relative exposures  of populations to  ambient air pollution in a wide range of urban
areas and estimate the trends which emerge. It is  hoped that dissemination of GEMS information
on levels, trends, and health significance of environmental contamination will permit UN member
countries to make national decisions for the improvement of environmental conditions of relevance
to public health.

 Summary of Environmental Data:

 Media: Air; surface and ground water; food sources

 Classes of compounds:

       GEMS/AIR:  Particulates; criteria pollutants (sulfur dioxide and some data on nitrogen
              dioxide, carbon monoxide, and lead)

       GEMS/WATER: Inorganic compounds; VOCs (benzene); semi-VOCs (phenol); pesticides;
              PCBs; microorganisms (total and fecal coliform); physical and chemical indicators
              of water quality; ions (including fluoride)

       GEMS/FOOD: Inorganic compounds; PCBs; pesticides; aflatoxins

 Type of data available: Summary statistics are available on specific agents for all GEMS databases;
       individual data  entries  are only available with permission from WHO and UNEP for
       GEMS/FOOD and GEMS/WATER; information on the availability  of individual data was
       unknown for GEMS/AIR at the time of publication

 Estimation versus observational data: All observational data

 Sample Design and Analysis:

       The gathering of data is done by national institutions of UN member countries with help
 from relevant UN agencies. To maintain uniformity, a standardized coding system is used for each
 database to transfer data between countries and the data center.  The data are checked and edited
 and any questions which arise are resolved through WHO headquarters. Countries receive reports
 from the data centers for scrutiny of their data. Any corrections or amendments are subsequently
 applied to the master database.

       Monitoring sites included in GEMS/AIR are large urban areas with three identifiable sites
within  the metropolitan area: city  center, industrial, and suburban.  Air sampling data for total
suspended particulate (TSP) and sulphur dioxide are collected by scientists from participating
countries. Data are generally collected on a 24-hour basis and reported to the Collaborating Center
on Air Pollution Control on a quarterly schedule.

       Monitoring stations in GEMS/WATER are selected from existing national or local networks
wherever possible; otherwise, new stations were established.  Priority is given to rivers, lakes, and
groundwaters used for water supply. Data are collected by national institutions on a schedule which
varies from  country to country and are forwarded to the WHO CCIW.

       Food contamination data in GEMS/FOOD includes chemical and biological agents arising
from environmental and industrial pollution, agricultural technology, food processing practices, and
natural sources.   Data  are collected by national food contamination monitoring programs in
countries producing the foodstuffs and importing countries at points of entry and are forwarded to
WHO headquarters.  Data items reflect  the food name and its country of origin, contaminant, year

 Objectives and Coverage:

        ATSDR, created by Congress in 1980, has the mission to prevent or mitigate adverse
 human health  effects and diminished quality of life resulting from exposure to hazardous
 substances in the environment.  To achieve this goal ATSDR conducts health assessments
 and consultations  at Superfund sites and other  sites; conducts or funds health studies of
 individuals exposed to hazardous materials at these sites; and develops toxicological profiles
 ?Tf™?md°US substances-  As Part of these activities,  ATSDR is  currently  developing
 HAZDAT,  a database  that records ATSDR activities.  At the time  of this writing, past
 ATSDR  data are being entered into  HAZDAT.   It is  anticipated that HAZDAT may be
 available to some other federal agencies beginning April 1992. It is not known when it will
 be available to  the general public.  Data in HAZDAT include: site characteristics; activities
 and site events; contaminants detected;  contaminant media;  maximum  concentration;
 population  impacted  by  the  site  or  event;  community  health  concerns;  ATSDR
 recommendations; environmental fate; exposure routes; and physical hazards at  the site or
 event.   HAZDAT also includes data from EPA's Comprehensive Environmental Response
 Compensation,  and Liability Information System (CERCLIS), including: CERCLIS number-
 site  name;  address; National Priority List (NPL)  status;  site  description; latitude  and
 longitude; and  operable units (specific locations at each site).  Substance-specific data from
 ATSDR toxicological profiles are included in HAZDAT:  presence on ATSDR's Priority List
 of Hazardous Substances; health effects by route and duration of exposure; metabolites;
 interactions; susceptible populations; and biomarkers of exposure and effects.  HAZDAT can
 be used by ATSDR personnel for research and information management purposes (e.g., to
 obtain a complete site history; for rapid access to toxicological data; to identify similarities
 of sites and events).

-------
Sample Design and Analysis:

       Activities of ATSDR  are  performed by three Divisions;  the  Division of Health
Assessment and Consultation, the Division of Health Studies, and the Division of Toxicology.
The Division of Health Assessment and Consultation conduct site assessments at Superfund
National Priorities List (NPL) sites and at sites where emergencies involving hazardous
materials have  occurred.     The  Environmental  Protection  Agency  (EPA) and state
environmental protection agencies usually alert ATSDR of an emergency event.  Emergency
response is jointly provided by ATSDR, EPA, and other government agencies involved in
emergency response. ATSDR provides recommendations for evacuation, spill clean up, etc.
The Division of Health Assessments and Consultation also conduct health  assessments at
other sites (indoor and outdoor environments), when requested. When substance information
is included in ATSDR's health assessments and consultations, the maximum concentration
of each substance  per media is included in HAZDAT.

       When known exposures to individuals at sites visited by ATSDR have occurred, long
term epidemiological and biological monitoring are conducted or funded by  the Division of
Health Studies.   Information on the activities  of the Division  of Health Studies  was
unavailable at the time of publication.

       Data from  each of these ATSDR investigations and current medical  literature have
been used by the  Division of Toxicology, in conjunction with EPA, to rank  275 substances
at toxic waste facilities in order of priority.  Toxicological profiles for 120 of these substances
have been developed and are continually updated based on new information. Future plans
include the development of profiles for the remaining substances.

               HISPANIC HEALTH AND NUTRITION EXAMINATION SURVEY
 Acronym: HHANES
 Sponsoring Agency: U.S. Department of Health and Human Services, Centers for Disease Control
        (CDC), National Center for Health Statistics
 Contact Person: Robert Murphy, National Center for Health Statistics, Room 900, 6525 Belcrest
        Road, Hyattsville, MD 20782, (301) 436-7068


 Objectives and Coverage:

        HHANES, a data collection effort conducted by the National Center for Health Statistics
 (NCHS)  from 1982 to 1984, was mandated to collect  health data on Hispanics and to derive
 estimates of health and nutritional status that are comparable to estimates available for the general
 population from the National Health and Nutrition Examination Survey (NHANES) programs (see
 the description of NHANES in Part I of this Inventory).  The goals of HHANES were:  (1) to
 estimate the national prevalence of selected diseases and risk factors in Hispanic populations  (2)
 to estimate distributions of selected health parameters, and (3) to document and investigate reasons
 for trends in selected diseases and risk factors. HHANES collected and disseminated data obtained
 from physical examinations, diagnostic tests, anthropometric measurements, laboratory analyses, and
 personal interviews.  A representative sample of Mexican Americans, Puerto Ricans, and Cuban
 Americans, who constituted approximately 76 percent  of the 1980 Hispanic population  in  the
 United States, were interviewed; 85 percent of those interviewed were also examined. The database
 was specifically designed to assess exposure in minority  populations (Hispanics) and Hispanics 6
 months to 19 years of age and 45 to 74 years of age. The data collected included information on
 exposure  to pesticides, lead, and other toxics as well as blood levels of a variety of toxicants and
 their metabolites.  HHANES was the first  special population survey undertaken by the NCHS.  It
 was designed to identify unmet health care needs of Hispanics and has been used to study blood
 lead levels in Hispanic children and cigarette consumption among Mexican American smokers.

 Summary of Environmental Data:

 Media: Human samples (blood, urine, hair)

 Classes of compounds: Inorganic compounds (trace metals, lead), semi-VOCs, pesticides, PCBs,
       cotinine, carboxyhemoglobin, thiocyanate, and erythrocyte protoporphyrin

Type of data available:   Individual data entries on  specific agents; summary statistics (e.g.,
       geometric and arithmetic  means,  percentage  of individuals  with elevated  levels, and
       percentage of individuals  with quantifiable  levels) on specific agents tested in sample
       populations

Estimation versus observational data:  All observational data
                                          1-87

-------
Sample Design and Analysis:

       HHANES used complex, multistage, stratified, clustered sample of defined populations to
obtain data representative of the health and nutritional status of Hispanics 6 months to 74 years
of age in the United States. The population studied was the civilian noninstitutionalized Hispanics
front three areas of the country:  Mexican Americans in the  Southwest (defined as California,
Arizona, New Mexico, Texas, and Colorado), Puerto Ricans in the New York City area (defined
as selected counties in New York, New Jersey, and Connecticut); and Cuban Americans m Bade
County (Miami), Florida.  Using 1980 census data, counties from these target survey areas were
identified and characterized by  Hispanic population density and  number.   Based  on  this
information, the sampling areas were identified.  The stratification variables used were number of
Hispanics, the percent of the population that was Hispanic, the ratio of the 1980 to 1970 Hispanic
population, median income, and the percent of the Hispanic population that was urban. Based on
these data,  households and individuals within households were chosen for inclusion.  Eligible
Hispanics 6 months to 19 years in age and 45 to 74 years of age were oversampled to improve the
reliability of estimates of their health characteristics and nutritional status.

       Information on a wide range of demographic variables was obtained including age, national
origin sex, income, education, and marital status. Physical examinations, diagnostic tests (including
blood pressure, electrocardiograms, and  dental examinations), anthropometnc measurements,
laboratory analyses (including urinalysis, biochemical analysis of whole blood and serum, and oral
glucose tolerance tests), personal interviews, and dietary interviews were conducted on individuals
Selected for participation.  Using standard analytic and QC/QA procedures, blood samples were
analyzed for pesticides, trace metals, lead, cotinine, carboxyhemoglobm, thiocyanate, PCBs, and
erythrocyte protoporphyrin, and urine samples were analyzed for pesticides and PCBs.  During a
pilot test, hair samples from a subsample of 12- to  19-year-olds were tested for selected trace
metals. Questions were asked regarding the type of heating fuel used, tobacco use (12- to 74-year-
olds), farmwork history, use of Kweli for head or body lice, and pesticide exposure (12- to 74-year-
olds).

Objectives and Coverage:

       IDB is a national database of spent fuel and radioactive waste inventories used for national
program planning, decision-making, and other program management  activities.  This database
compiles  the historical waste inventories through the most recent data year.  These include
inventories from  commercial as well  as  DOE facilities, except spent fuels produced from the
manufacture of nuclear weapons.  Information on spent fuels and wastes are included for nuclear
reactors, storage facilities, reprocessing facilities, uranium mill tailings, and miscellaneous sources
defined as part of the Resource Conservation and Recovery Act (RCRA).
Summary of Environmental Data:

Media: Bulk chemicals, soil

Classes of compounds: Radionuclides (waste forms include spent fuel, highly radioactive material,
       transuranic  wastes,  low-level waste,  uranium  mill  tailings, miscellaneous  radioactive
       materials, and mixed low-level wastes)

Type of data available:  Summary statistics on specific waste forms (available for specific sites by
       year)

Estimation versus observation data: All data are inventory amounts; direct measurements are not
       available
                                           1-92

-------
 Sample Design and Analysis:

       Data are included from all commercial and government reactors, special fuel associated with
 government-sponsored research and demonstration programs, universities, private industries, storage
 facilities, and fuel reprocessing plants.  Over the years, waste regulations have been revised, waste
 category definitions have changed, measurement instrumentation and calibration methods have been
 improved,  and record-keeping  has been upgraded at all waste generating and  receiving  sites.
 Therefore, the quality of the information over time has changed.  In addition to the spent fuel and
 wastes from processing, uranium mill tailing information is available from all licensed commercial
 sites and from restoration sites. Sites are selected for restoration under the Uranium Mill Tailings
 Remedial Action Program (UMTRAP), the Formerly Utilized Sites Remedial Action Program
 (FUSRAP), the Decontamination and Decommissioning Program (D&D), and the Surplus Facilities
 Management Program (SFMP). UMTRAP site criterion is that the processing site must have had
 all or substantially all of the uranium production for sale to federal agencies prior to January 1971.
 FUSRAP site criterion is that  the sites were formerly used to support the nuclear activities of
 DOE's  predecessor  agencies  (the Manhattan  Engineer  District and  the  Atomic  Energy
 Commission).  The D&D program objective is to decontaminate and decommission inactive, surplus
 DOE facilities formerly associated with the government's defense efforts.  The SFMP's objective
 is to decontaminate and decommission inactive, surplus DOE facilities formerly associated with
 civilian projects.

       Information is available by  site.  However, the dispersion from  the  site, apart  from
 transportation of packaged waste to waste disposal sites, is not available.

Objectives and Coverage:

       IMPROVE consists of air quality data from Class I ("Clean Air") areas that include national
parks and wilderness areas with special prevention of significant deterioration  (PSD) status.  This
monitoring program is aninteragency effort with the U.S. Environmental Protection Agency (EPA)
and the U.S. Department of the Interior, including the U.S. Forest Service, U.S. Fish and Wildlife
Service,  and the Bureau of Land Management, providing financial support.   NPS provides
monitoring and maintains data to determine spatial  and temporal  trends in visibility in the NPS
parks and wilderness areas for which visibility is an air quality related value.  Monitoring is also
conducted to  determine what species of participates  (e.g., sulfates, nitrates) causes visibility
problems. Data are presently used for visibility research. The data will also be used for regulatory
purposes when a baseline for visibility has been established.
Summary of Environmental Data:

Media: Air

Classes of compounds:  Particulates, criteria pollutants (sulfur dioxide), acid aerosols, inorganic
       compounds (including sulfates, nitrates)

Type of data available:  Individual data entries and summary statistics are available

Estimation versus observational data:  All observational data
                                           1-96

-------
 Sample Design and Analysis:

         Class I national parks with 6,000 acres of land or greater and class I wilderness areas with
 5,000 or greater acres of land (as of August 7,1977)) with PSD status are included in this sampling
 program.   Of these sites, those where air quality permit investigations have been made by state
 environmental protection agencies are selected for monitoring.

       Since fine particles cause most of the visibility degradation in protected areas, these are
 included in this air  monitoring program. Ambient sulfur dioxide measurements are also collected
 at approximately  twenty of these sites, selected to represent each geographic area of the United
 States Sample locations in the parks and wilderness areas include areas away from local sources
 (e.g., a parking lot) and easily accessible areas.  Two-24 hour samples per week are collected
 throughout the year using continuous analyzers. Particulate filters are changed on a regular basis
 by NPS personnel and are analyzed at the University of California, Davis,  CA.  Information on
 sampling and analysis of acid aerosols and inorganic compounds was not available at the time of
 publication.

       98518, Las Vegas, Nevada 89193-8518, (702) 295-0961
Objectives and Coverage:

       The information in OHSP is used for monitoring and documentation of human radionuclide
exposure of families residing in communities and ranches surrounding the Nevada test site (Nevada,
Utah, and California locations)!  Whole body and lung counts, as well as radiochemical bioassays
of urine  and fecal samples, are conducted.  The database primarily includes internal radiation
dosimetry measurements on a moderate size cohort over a twenty year period.  Supporting data on
noble gas or radionuclide measurements in air, water, animal tissue, and occasionally in plants are
also maintained by the laboratory in charge of the Internal Radiation Dosimetry System. The EPA
and DOE use results obtained from OHSP, along with  these other data, to evaluate the total
radiological dose to the region from the Nevada test site. Data in OHSP include names and social
security numbers and are therefore considered confidential.  Summary data may be obtained upon
request and approval.
Summary of Environmental Data:

Media:  Human samples (another related database maintained by EPA, the Sample Tracking and
       Data Management System (STDMS), covers water, air, and animal samples)

                                         1-100

-------
Sample Design and Analysis:

       The original  monitoring program started  in December  1970 with  34 families  (142
individuals) who resided in communities and ranches surrounding the Nevada test site. They were
selected on the basis of their willingness to participate in the program  and their location of
residence in relation to possible releases from the site. Families who resided in areas not affected
by such fallout were also selected to participate as controls. In 1981, families of the operators of
the community monitoring stations were added to the program.

       Urine samples are collected from the participants and analyzed for radionuclides. on a 6-
month basis (less often when traveling or scheduling problems arise).  The original 34 families are
sampled in the  spring and fall, and  the additional families in the summer  and winter.   If
radionuclides are detected that may be excreted mainly in feces, then fecal samples are collected.
Otherwise only  urine samples are  collected and analyzed.  Whole body and lung counts  are
conducted on the same schedule.

      If an individual or a family moves out of this geographic region, they are dropped from the
monitoring program and replaced with a new family within the region who is willing to participate.

Objectives and Coverage:

       The  Lake Analysis  Management  System (LAMS)  is a compilation of multiple EPA
Environmental Research Laboratory data containing physical and biological information on water,
sediment, fish, biota (e.g., ducks), and phytoplankton from the Great Lakes Basin, including the
Canadian portion.  The primary objective of this database is to provide research information for
various Great Lakes projects.
 Summary of Environmental Data:

 Media: Water (lakes), sediment

 Classes of compounds: Inorganic compounds, PCBs, pesticides

 Type of data available: Individual data entries on specific agents

 Estimation versus observational data:  Both observational and estimated data
                                          1-104

-------
  Sample Design and Analysis:

        LAMS currently includes data from approximately 12 projects; examples include the Green
  Bay Mass Balance Project and the Upper Great Lakes Connecting Channel Study. Sample design
  and analysis varies depending on the individual project. Generally, a hypothesis is developed based
  on a series of questions (e.g., what is the optimal expenditure of pollution control resources)   A
  sampling framework is established (e.g., based on source, transport, fate, exposure, dose).  Sites are
  chosen based primarily on recommendations by EPA's Regions 2 and 5 in collaboration with the
  Great Lakes National Program in Chicago. Examples of sampling methods (e.g., for the Green Bay
  project) include pumping and filtering of water samples from different depths, coring for sediment
  samples, and taking  biological samples with nets.  Sampling is done in conjunction with other
  organizations involved with the specific project, such as state  agencies, individual companies, and
  EPA regions.  When necessary, estimated data are derived from existing literature.

       89119, (702) 798-2664
Objectives and Coverage:

       The Lockheed-EPA database was established to evaluate the performance of the indicator
parameters specified for use in the Resource Conservation and Recovery Act (RCRA) ground-
water monitoring program.  After finding that the initially-specified indicators were unreliable,
Lockheed-EPA recommended alternatives. The database is now being used to evaluate the success
of other regulatory monitoring programs, to develop ground-water contamination profiles for
hazardous waste disposal sites, and to design industry-specific ground-water monitoring systems to
protect human health and the environment.

       The  database consists of  data obtained from the records of various  state and federal
agencies responsible for ongoing investigations of waste disposal sites; these agencies, not Lockheed,
collect and analyze samples. The  database contains primarily ground-water monitoring  data, but
also contains some soil data from approximately 550 hazardous waste disposal  site investigations
across the United States.   These sites  are regulated by various laws including RCRA and the
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).  The data
can be sorted by regulatory classification (e.g., RCRA site, CERCLA site, etc.); by industry type
(e.g., mixed-disposal site, aerospace, wood-treatment, etc.); by location/site, industry, region, state,
or nation; or by sampling date.

Summary of Environmental Data:

Media:  Ground water, soil (Superfund sites)

Classes of compounds: Ions (e.g., chloride and fluoride), physical and chemical indicators of water
        quality (e.g., acidity, alkalinity, color, odor, turbidity, dissolved oxygen, hardness, BOD,
        salinity), inorganic compounds, VOCs, trihalomethanes,  semi-VOCs,  pesticides, PCBs,
        dioxins/furans, radionuclides

Type of data available:  Individual data entries and summary statistics on specific agents; statistics
        (frequency of detection, average  concentration, mean concentration, and data variance)
        have been generated for specific wells, individual sites, specific industries, EPA regions,
        states, regulatory classification, and national summaries
                                          1-107

-------
Estimation versus observational data: All observational data

Sample Design and Analysis:

       Sample collection and analysis are performed by various state and federal agencies, who are
also responsible for  performing standard QA/QC procedures.  Lockheed-EPA reviews the  data
collected from agency records to ensure that the results are appropriate for entry into the database
(i.e., that they are  ground-water and not surface-water or leachate  monitoring results,  etc.).
Information from the records (e.g., chemical/contaminant name, chemical concentration, collection
frequency, etc.) is then entered into the database and tabulated. Basic statistics generated include
frequency of detection, average, concentration, and variance of measurements.  Statistics are used
to track trends in contaminant occurrence as a function of geographic location, industry type, and/or
regulatory classification.

       757.4441
Objectives and Coverage:

       LTM is a database designed to assess long-term trends in the acid-base status of individual
lakes or streams in six rural areas: Maine, Vermont, the Adirondack and Catskill Mountain regions
of New York, the Upper Midwest, and the Colorado Rockies. The results of monthly or quarterly
samples taken in these lakes and streams are compiled. This information identifies any changes in
pH status and other parameters which may have occurred over the sampled time period (1983 -
present) and is indicative of trends in the region. Lakes and streams in other rural and urban areas
will be included in this project in the future.
Summary of Environmental Data

Media:  Surface water

Classes of compounds:  Inorganic compounds; physical and chemical indicators of water quality;
      ions

Type of data available:  Individual data entries are available on specific agents

Estimation versus observational data:  All observational data
                                         1-111

-------
Sample Design and Analysis:

       Sites were selected based on pre-existing data from studies of acid deposition.  Water
samples are collected 1 meter below the surface from a boat in each lake and mid-stream. Samples
are collected monthly in the Catskill Mountain regions; quarterly in Maine, Vermont and the Upper
Midwest, and three times each summer in the Colorado Rockies.  Water samples are transported
to 1 of 6 laboratories nationwide, where they are analyzed for pH, acid neutralizing capacity, sulfate,
nitrate, chloride, calcium, sodium, potassium, magnesium, total aluminum, dissolved organic carbon,
electrical conductivity and color. In some locations, pH is measured in the field as well as in the
laboratory using a pH meter.

       Other monitoring networks, e.g., the National Acid Deposition Program-National Trends
Network (NADP-NTN) (see separate entry for Acid Deposition System for a description of NADP-
NTN), and the Multi-state Atmospheric Pollution and Power Production Study (MAPIIIS) (a
privately funded database that provides regional air data), are used to obtain information on acid

can be made in the lakes and streams of the LTM.

       Sites monitored have been the same throughout the project, although there are plans to
include other lakes and streams in the future.

 Objectives and Coverage:

        MPRS includes data on spills and potential spills (whenever there is a potential for a vessel
 to spill its contents,  e.g., a grounding) into the navigable waters of the United States and on any
 land or air releases to U.S. coastal zones that the Coast Guard responded to.  Data are classified
 into seven categories of information:  chemicals,  facilities, vessels,  resources, violations, materials,
 and personnel. Spill and release information includes data on the product and amount spilled or
 released; the location, date, and time of the spill or release; the removal party; the funds expended;
 and the source (facility or vessel) of the spill or  release.  These data are used for justification of
 criminal action, and for monitoring and research purposes.

Sample Design and Analysis:

       Field units of the U.S. Coast Guard respond to reported spills, potential spills, or releases
in navigable waters and in other media within their jurisdiction. Water, air, and/or soil samples are
collected when circumstances justify the need for sampling.  These circumstances include source
identification and justification of criminal action, and depend upon the characteristics of the spilled
or released material (e.g., volatility).  Samples are taken at the source, whenever necessary and
possible  and in areas surrounding the source.  If the source is unknown, samples are taken from
the spill and suspected sources. The U.S. Coast Guard Central Oil Identification Laboratory
(COIL) compares oil spill samples with suspected source oil samples using gas chromatography for
source identification.  Samples other than oil are analyzed by a local contractor.

 Objectives and Coverage:

        The Food Safety and Inspection Service (FSIS) of the USDA collects samples of meat and
 poultry at slaughtering establishments and from import shipments at ports of entry as part of its
 National  Residue  Program.   The samples are analyzed  for  the  presence  of unacceptable
 concentrations of chemical compounds that may contaminate meat  and poultry presented for
 inspection.  The  results of these analyses are contained in MARCIS.  The compounds primarily
 include: pesticide chemicals approved for direct application to livestock and poultry or for treating
 crops that become  components  of animal  feed or that  are  used  in some  way in the farm
 environment;  animal drugs used to  treat or prevent diseases or to enhance production; and
 environmental contaminants.  (The Environmental Protection Agency (EPA) and the Food and
 Drug Administration  (FDA)  establish acceptable  levels  of  residues  (tolerances)  for  these
 compounds in their respective areas of responsibility.) The MARCIS program is carried out as part
 of the Agency's responsibilities under  the Federal Meat Inspection Act and the Poultry Products
 Inspection Act to  ensure that USDA-inspected products in commerce are safe, wholesome, and free
 of adulterating residues.   Results are evaluated to indicate prevalence and concentrations  of
 residues, to identify producers marketing animals with violative concentrations of residues, evaluate
 residue trends, and identify problems within the industry for which  corrective efforts may be
 needed. The National Residue Program also maintains the Residue Violation Information System
 (RVIS) database, which includes followup data on violations and is used by FSIS and the FDA.

Sample Design and Analysis:

       Residue testing of animals slaughtered in the United States is divided into three major
activities:  monitoring, surveillance, and exploratory projects. Each year, compounds are selected
for monitoring based on the availability of laboratory methodology (because of the large number
of potential residues that may occur in the food chain, analytical methods are not available for all
compounds of interest) and the existence of an FSIS evaluation system for the compounds to be
tested This system classifies each pesticide, animal drug, and environmental contaminant according
to its potential for harmful residues to occur in animals at slaughter, and inherent toxicity.  It is
intended for FSIS use as a guideline and not for the development of formal quantitative estimates
of risk from meatborne residues.  An advisory board of scientists from EPA, FDA, and USDA
identify any  significant  new information  that may affect a compound classification.  Once
compounds are selected and suitable methods are  available, a monitoring program based on
unbiased sampling, is designed to provide information on the occurrence of residue violations m
specified animal populations.   The number of samples chosen in  an  annual plan  for a given
compound-species combination is designed to detect a national problem  that affects a specified
percentage of the animal population  of interest (the number of samples generally is chosen to
provide 95%  probability of detecting at least one  violation when one  percent  of  the  animal
population sampled is violative).

       When the results of monitoring indicate that producers are marketing animals for slaughter
with violative concentrations of residues, the animals are subjected to ongoing sampling and testing'
(termed surveillance sampling) until  compliance  is demonstrated.  This sampling is directed at
particular  carcasses or products based on monitoring results.  In-plant testing  procedures may be
performed by the inspector. Samples indicating the presence of a residue are submitted to an FSIS
laboratory for analysis.  Test results indicate the appropriate regulatory action.

       When test results indicate a violative concentration of residues in an imported product,
subsequent shipments of the same product group from the establishment are retained at the port
of entry until laboratory results are  known.  If results are positive, the suspect product is not
permitted to move into commerce. All shipments of the product from that country are placed on
an increased testing schedule until a record of compliance is re-established for the country.

       In addition, exploratory projects are often conducted to evaluate the occurrence of residues
in animals for which no safe limits have yet been established, to evaluate new monitoring methods
 and approaches, and for a variety of other reasons. These  studies may be nationwide or limited to
 specific geographic areas.  Sample collection may be random and statistically  based, or biased to
 obtain "worst case" information.  The results are given either to the FDA, which has responsibility
 for  establishing tolerances for animal drugs and environmental contaminants in food, or to the
 EPA, which sets pesticide tolerances  in food.  These results are included in MARCIS.

Contact Person: Edward Kohout, 9700 South Cass Avenue, Argonne, IL 60439, (708) 972-7644
Objectives and Coverage:

       MSCET provides monthly air emissions estimates and identifies trends for oxides of nitrogen
(NOJ, sulfur dioxide (SO2), arid nonmethane volatile organic compounds (VOCs) by state, region,
season, and sector (e.g., industrial, commercial, residential).  Estimates are based on a variety of
information, including energy consumption,  type  of technology  used,  and  emission  control
technology. MSCET predominantly uses estimated data and modeling to generate emissions factors
and other information. MSCET has developed methodologies and estimates for both stationary
and mobile emissions sources. Estimates are available for the 48 contiguous United States and are
used for monitoring, research, and regulatory purposes.  MSCET also provides "flash reports," which
are recent emission trends that provide a forecast for one additional year beyond the year cited in
the most recently published EPA Trends Report.

       As with most estimates, a level of uncertainty is  associated with MSCET emission estimates
due to lack of or insufficient data in some areas. The database is, however,  useful in making
comparisons across different regions and over time.

-------
Sample Design and Analysis:

       MSCET developed four separate methodologies for calculating emissions estimates based
on emission source category.  Methodologies were developed for: the electric utility industry, the
transportation sector, the copper smelting industry, and all remaining sources, termed ICRIM
(industrial fuel combustion,  commercial/residential fuel combustion, industrial processes, and
miscellaneous sources).   Whenever possible, MSCET estimated  emissions  at  the  individual
combustor (e.g., boiler) level; when this level of data were not available, emissions were estimated
based on the type of technology used.

       For electric utility estimates, MSCET used a consumption/emission factor (CEF) method,
in which the amount of fuel consumed each month was multiplied by an appropriate emission
factor, which included reductions in emissions if pollution control devices were used.  In special
cases, direct estimation methods (e.g., continuous emission monitors) were used instead of the CEF
method.

       For the transportation  sector, MSCET methodology was based  on an emission factor.
Separate algorithms were used to estimate on-highway and off-highway (e.g., locomotive, aviation,
and waterway) emissions. For on-highway sources, emissions were calculated using vehicle-miles-
traveled (VMT) data and emission factors from EPA's MOBILE4 model, which includes speed,
temperature, and  altitude as major parameters.  The U.S. Department  of Transportation's
publication Highway Statistics provided VMT by state and road type. For off-highway sources, EPA
AP-42 Form was used, as well as sector-specific documents which provided  statistics on operational
and fuel consumption activity data.  The Transportation and Energy  and Emissions  Modeling
System  (TEEMS) methodology was used to estimate various transportation emissions.

       For copper smelters, data were supplied primarily by state air pollution control agencies and
were computed using a plant-level sulfur mass balance technique based on actual measurements of
fugitive emissions.   NOx and VOC  emissions  from copper smelters  are considered  to be
insignificant; therefore, these were estimated differently, using the ICRIM methodology described
below. When mass balance data were unavailable, data from the EPA AP-42 Form and information
from continuous emission monitors were used to estimate sulfur dioxide  emissions. These data
supplemented the  1985  National Acid Precipitation Assessment Program (NAPAP) Emissions
Inventory data. In the absence of available sulfur-content value  and heat value data at the state
level,  national-level sulfur-content values and heat values for the specific fuel type were used.
Confidentiality of plant-level data prevented comprehensive quality assurance checks.

       Methodology  for the ICRIM sector utilized  data  from =the 1985  NAPAP Emissions
Inventory, which provided base-year estimates. When available, state-level activity data (usually
from the State Energy Data System, or SEDS, database) were also used. MSCET then developed
trends data using sector-specific growth rates, often derived from time-series data from the EPA's
National Air Pollutant Emission Estimates, 1940-1987 (also known as the EPA Trends Report), or
from Federal Reserve Board (FRB) indexes of industrial production. The ICRIM methodology
utilized a "shift-share" approach (e.g., states with a higher relative growth gain in share), based on
NAPAP data.  Monthly emissions were estimated by disaggregating annual emissions based on
monthly activity data. Monthly shares  before 1985 were held .constant because these data were
missing. If no appropriate trend indicator could be identified, emissions were held constant at the
levels reported in the 1985 NAPAP Inventory.

       Other data sources for the ICRTM emissions estimates included: the EIA's Monthly Energy
Review for fuel consumption data; the U.S. Department of Commerce Survey of Current Business
for industrial production data; DOE's Quarterly Coal Report; the Natural Gas Monthly; and data
collected by the National Climatic Data Center (state-specific, population-weighted, heating-degree-
day data).

       This inventory of monthly emissions of SO2 for 1975-1983 was designed to reflect actual
annual SO2 emissions variability. The database has been discontinued. Data include state-total and
source-category-specific monthly SO2 emissions  for the continental U.S. Computation of monthly
emission estimates involved a portioning of total annual SO2 emissions to monthly values through
the use of several databases.  Also see the  separate entries for the Month and State Current
Emissions  Trends (MSCET) and for the Acid Deposition Data Network (ADDNET).

       NATIONAL ACTO PRECIPITATION ASSESSMENT PROGRAM (VERSION 2)

Contact Person:  Janice Wagner, U.S. EPA, MD-62, Research Triangle  Park, NC 27711, (919)
       541-1818
Objectives and Coverage:

       The National Acid Precipitation Assessment Program (NAPAP) was authorized by Congress
under the Acid Precipitation Act of 1980. This major research program was initiated to study the
causes and potential adverse effects of acid deposition in and around the  United States.  A
fundamental  objective  of  the NAPAP research was to investigate emissions sources that may
contribute to acid deposition. To achieve this objective, a NAPAP Task Group on Emissions and
Controls developed historical and current (1985) inventories of acid deposition precursor emissions.
Since long range pollutant transport plays a critical role in acid deposition, emissions inventories
encompassed geographic areas larger than those where the acidification and deposition effects were
observed. The investigation of acid precipitation in the United States (particularly in the northeast)
and in Canada required development of emissions inventories for all states and provinces in both
countries.

       The NAPAP assembled data in two phases.  The first phase involved  data collection and
quality assurance of total emissions and source characteristics of acid deposition precursors. Data
in the  NAPAP Emissions  Inventory  include  point  source  emissions  and facility data (i.e.
documentation of physical parameters  such as stack height) for 9,175 plants and 66,308 points
(stacks) in the United States and Canada, as well as area source emissions estimates (e.g., for motor
vehicle emissions) for 3,073 United States counties and 10 Canadian provinces. Emissions estimates
of natural sources  of total suspended participates were also determined and included in the 1985
U.S. NAPAP Natural Particulate Emissions Inventory.  Since these  database characteristics are
similar, although the source is  different, the database  characteristics described in this summary
pertain to both.

       The second phase  included the development of a modelers' emissions  inventory in which
total emissions data were converted to a format suitable for use as input to regional atmospheric
transport models.  Hourly emissions by day of the week and season were calculated for speciated
aggregate emissions. These models are used to study source-receptor relationships and regional
impacts of pollutants involved in acid deposition.

       (See the separate entries in part I of this inventory for the Acid Deposition System (ADS)
and in Part II for the Acid Deposition Data Network (ADDNET).)

Summary of Environmental Data:

Media:  Air (point and area source emissions)

Classes of compounds: Criteria pollutants (except ozone), VOCs, total hydrocarbons, total and size
       fractionated particulates, acids/acid aerosols, inorganic compounds

Types of data available:  Individual data entries are available on specific agents

Estimation versus observational data:  Predominantly estimated data

Sample Design and Analysis:

       EPA worked closely with state air pollution programs to plan, fund, assemble and ensure
the quality of the inventory data.  EPA and states have the authority to collect required emissions
data under Title 40, CFR, Part 51, Section 51.321-51.323.  Environment Canada was the regulatory
agency responsible for developing Canadian national emissions inventories.  In a manner analogous
to the State-EPA partnership in the United States, Environment Canada worked with provincial
environment ministries to collect emissions data for Canadian industries.

       Both the emissions  and modelers'  emissions inventories are divided  into point and area
sources.  The database contains information on the precise location of point sources that emitted
at least 100 tons per year of sulfur dioxide, nitrogen oxides, VOCs, total suspended particulates, or
carbon monoxide during the 1985 base year.  Area sources include mobile and stationary sources
too numerous and too small to be listed individually, such as residential space heating. The United
States point and area source emissions, as well as facility data (information on the engineering
design and performance of industrial processes),  were generated by  state  agencies using the
National Emissions Data System (NEDS) methodology, in which emissions are estimated directly
for each source. Individual state  confidentiality restrictions prevented  the complete reporting of
some priority data elements.  Environment Canada calculated source  emissions for Canada
following a similar methodology.

       In addition to criteria pollutants, emissions estimates for primary sulfate particulate,  total
hydrocarbons, VOCs, hydrogen chloride, hydrogen fluoride, and ammonia,  which also play an
important role in the acid deposition process, were developed by EPA and Environment Canada
through the application of emission factors.

       Estimates of natural alkaline particulate emissions  from unpaved roads, wind erosion, and
dust storms (United States only) were also  developed and included in the 1985 U.S. NAPAP
Natural Particulate Emissions Inventory.

       The total emissions data were converted into a modelers' inventory of emissions (using the
Flexible Regional Emissions Data System - FREDS) in a format that can be used as input to
regional atmospheric transport models. This format includes a grid of specific geographic areas,
hourly emissions data, and is speciated (e.g., information on stable product chemical species rather
than emitted chemical species is included; VOCs and TSP emissions  are broken into various
chemical species classes, which include 32 classes of VOCs, nitrogen dioxide and nitric oxide,
sodium calcium, potassium  and magnesium).

Objectives and Coverage:

       NAMS, part of the State and Local Air Monitoring Stations (SLAMS) network (see separate
entry for SLAMS), was established to monitor ambient air concentrations of criteria pollutants and
particulates as well as some other pollutants in areas with high pollutant concentrations and high
population exposure. These stations meet stricter criteria than the rest of SLAMS for siting (fixed
sites in areas of high population),  and for instrument selection (all equipment at NAMS must meet
the standards of the "List of Designated Reference and Equivalent Methods"; other SLAMS sites
must only meet these criteria if they are used to designate attainment or non-attainment status for
compliance with the Clean Air Act).  Location of NAMS sites do not change over time, providing
continuity in monitoring. NAMS data are submitted at least quarterly (often monthly) by states to
OAQPS. Data obtained from NAMS (and other SLAMS sites) comprise most of the data found
in the Air Quality Subsystem (AQS) of the Aerometric Information Retrieval System (AIRS) (see
separate entries for AQS in Part I and AIRS in Part II for further information).

       Detailed information was not available at the time of publication.

Objectives and Coverage:

       NATICH was established to assist state and local air pollution agencies in developing and
implementing air toxics control programs. Its primary purpose is to collect, classify, and disseminate
air toxics information from  state and  local agencies, the U.S.  EPA,  and other federal  and
international agencies, thereby facilitating the exchange  of  information  about air toxics  and
regulatory/monitoring programs.  Information about the activities  of various agencies,  problems
encountered by these  agencies, and agency contacts  can  be  found in the database as well as
information about air pollutants (e.g., permit decisions,  ambient air  and source emissions test data,
EPA risk assessment information). Bibliographic citations for published studies are also available.

       Data from all  federal, state, and  local regulatory/control  agencies are included in the
database. As a result, the database covers all types of air toxics  studies conducted in different
locations and environments.  The data in NATICH are not available through  other databases.
NATICH is presently linked to EPA's Toxic Release Inventory (TRI). (TRI contains information
submitted by industry under the provisions of the Emergency Planning and Community Right to
Know Act.)  In the future, NATICH may also be linked to EPA's Aerometric  Information Retrieval
System (AERS).


Summary of Environmental Data:

Media: Air

Classes of compounds:  Criteria pollutants, inorganic compounds, VOCs,  semi-VOCs, PCBs,

Type of  data available: Individual data entries on specific agents; summary statistics (including
       pollutant information, e.g., information on health effects, exposure  assessment), ambient
       monitoring data, etc.) on specific agents.  Data can be sorted by activity (e.g.,  emissions
       testing for traditional sources, ambient monitoring), by pollutant (e.g., by name, code), or
       by source category. Bibliographic and agency information  are also available.

Sample Design and Analysis:

       NATICH compiles data received from state and local agencies; it does not itself collect or
analyze samples, nor does it review or analyze agency data.   NAITCH does not  evaluate the
suitability of agency  sampling  techniques or analytical methods for the  determination  of risk
assessment,  air standards, or criteria.  NATICH includes data  from all types of air toxics studies
conducted in various locations throughout the United States.

       The Clearinghouse collects information annually by sending data collection forms to all state
and local agencies.  Information may be submitted in three ways: (1) agency responses to annual
surveys, (2)  direct entry of data by agencies, and (3) electronic transfer of large  data files.  The
information thus acquired is classified by agency, pollutant, and emission source, and includes data
on general agency facts (including  address and agency contacts), regulatory program descriptions
and contacts, permits, acceptable ambient concentrations, ambient air monitoring studies, source
tests, emissions  inventories, research and methods  development,  and supporting publications.
Citations and abstracts are included for published EPA, National Institute for Occupational Safety
and Health (NIOSH), and other federal/international agency documents, such as emission factors
documents, health assessments,  source sampling/ambient monitoring methodologies, and technical
monitoring documents. Ongoing  EPA and NIOSH research projects, such as chemical  hazard
information  profiles and epidemiology studies, are also cited and abstracted.

       Sources Characterization Branch, 6001 Executive Boulevard, Room 220, Rockville, MD
       20852, (301) 443-0454
Objectives and Coverage:

       The  NCPDI,  developed by the National  Oceanic and  Atmospheric Administration's
Pollution Sources  Characterization  Branch,  contains pollutant loading estimates for all point,
nonpoint, and riverine sources located in coastal areas that discharge to the estuarine, coastal, and
oceanic waters of the contiguous United States (excluding the Great Lakes). Discharge estimates
for nine separate classes of pollutants in nine major source categories are included in this database.
The estimates were originally made for the base year 1982, but can be considered to approximate
pollutant discharge conditions during  the period 1980-1985.  A series of projects are currently
underway to improve and refine the estimates for selected pollutant source categories and coastal
areas.  Information in this database is provided to resource managers at the federal, state, and local
level to help develop effective management strategies to protect and restore these waters.

       The  development of these data is one of  several interrelated activities  of NOAA.  A
separate  database  is maintained for each of these activities (see the National Status and Trends
Program  and  the National  Shellfish Register  of Classified Estuarine Waters  for descriptions of
related NOAA databases).  Each of these databases use the same spatial framework and together
are used  by NOAA for the  strategic assessment of the Nation's coastal and oceanic resources.

Summary of Environmental Data:

Media: Surface water

Classes of compounds:  Inorganic compounds; pesticides (1982 and 1987 data available for 35
       pesticides; original 1982 data available only for organochlorine pesticides); microorganisms;
       PCBs (original 1982 data only); physical and chemical indicators of water quality; other
       (petroleum hydrocarbons, nutrients, wastewater treatment sludges, and flow)

Type of data available:  Individual data entries and summary statistics are available on specific
       agents

Estimation versus observational data:  Most values based on estimates; some observational data
                                          1-138

-------
Sample Design and Analysis:

       The NCPDI uses NOAA's National Estuarine Inventory (NEI) (see separate entry in Part
II) data atlas, which was created to provide a spatial framework that could be used in several
related NOAA projects. The spatial framework developed was the estuarine drainage area (EDA),
defined by NOAA as  that portion of a watershed  that most directly affects an estuary  and is
delineated by U.S. Geological Survey (USGS) cataloging units and the head of the tide. Two atlas
volumes were  subsequently  published  detailing the land use  and physical  and  hydrologic
characteristics of the estuarine systems within the NEI.

       The NCPDI was developed for three geographic regions in the United States: the Gulf of
Mexico, East Coast, and West Coast. Seasonal and annual estimates of pollutant discharges from
source categories were made for the base year,  1982, in each of these regions.  Estimates are
currently being updated to  1987 and will be completed in the next few years (updates have been
completed for the Gulf of Mexico).  Source categories for the 1982 estimates include:  point
sources, urban andnonurban non-point sources, sources upstream of coastal areas, irrigation return
flow,  oil and gas operations, marine transportation operations, accidental  spills,  and dredging
operations.  Only the point, nonpoint, and upstream source categories are included in the 1987
estimates.

        The Land Use Data Analysis (LUDA) program of the USGS, which compiles data for 40
different types of land use in the United States, was the  primary source of land use data for the
NCPDI. Other sources, such as the National Resources  Inventory of the U.S. Soil Conservation
Service; the Bureau of the Census; the Census of Agriculture; and state, regional, and city planning
agencies were also used. The result was a set of consistent land use estimates in acres that were
used for analysis in each of the geographical regions. These data indicate the amount of surface
area occupied by land use activities that affect pollutants contained in stormwater runoff.

       Pollution estimates for each source category include: the level of activity in the base year;
the quantity of wastewater  or runoff discharged per unit of output or over a specified period of
time;  and the concentrations of pollutants in wastewater or runoff. For point sources, discharges
are estimated primarily through EPA and state National  Pollution Discharge Elimination System
(NPDES) permit and compliance files. If such information is inaccurate or incomplete, engineering
estimates  of typical pollutant  concentrations are made based on the facility type. For nonurban
nonpoint sources in the East Coast, the Simulator for Water Resources on Rural Basins Model, a
watershed modeling program, is used to estimate runoff and sediment  discharge.  Nitrogen and
phosphorous discharges are based on the Cornell University Nutrient Simulation Model. Estimates
of pollutant discharges for  other constituents are made based on these parameters. For urban
nonpoint sources, the volume of runoff is estimated and the pollutant load is calculated using
information obtained from a former EPA database, the National Urban Runoff Program (NURP)
(NURP has been  discontinued, however,  urban runoff  data are not collected by  cities). For
upstream  sources,  monitoring  information from USGS National  Stream-Quality  Accounting
Network (NASQAN) stations is used to estimate  pollutant mass  loadings.  A detailed description
of these estimation methods is included in a set of Methods Documents.

       Contaminants, 4401 North Fairfax Drive, Room 330, Arlington, VA 22203, (703) 358-2148
Objectives and Coverage:

       Since 1967, the U.S. Fish and Wildlife Service (FWS) has periodically analyzed residues of
selected organochlorine contaminants and potentially toxic elements in samples of fish and birds
collected from a nationwide network of stations.  This program, which originated as the FWS
segment of the National Pesticide Monitoring Program (a multiagency monitoring effort), is now
maintained by the FWS as the National Contaminant Biomonitoring Program (NCBP).  NCBP
documents temporal and geographic trends in concentrations of environmental contaminants that
may threaten  fish and wildlife and provides information on  the success of regulatory actions
intended to reduce environmental concentrations of toxic materials. The database covers freshwater
streams and interior upland and wetland habitats.

       The NCBP is scheduled to change its name and sample design in October  1992; the name
will become the Biomonitoring of Environmental Status and Trends Program. In addition, the data
will be made accessible  to the general public.  At present, it is only available through journal
articles.
Summary of Environmental Data:

Media:  Fish and bird samples

Classes of compounds: Pesticides, PCBs, VOCs, semi-VOCs, and inorganic compounds in fish
       (earlier data do not include the toxic metals and PCBs), pesticides and PCBs in birds

Type of data available: Individual data entries and summary statistics are available on specific
       agents

Estimation versus observational data: All observational data
                                          1-143

-------
Sample Design and Analysis:

       Freshwater fish were collected from stations at key points in major rivers throughout the
United States and in the Great Lakes from 1967 to 1988 at approximately 2 to 3 year intervals. The
species of fish collected and statistical representativeness vary by region and year. The frequency
of measurements and locations where  samples were collected could bias site-specific evaluations.
Three samples were collected from each station; two of a representative bottom-feeding species and
one of a representative predatory species.  Each were analyzed for organochlorine  chemicals
(pesticides, PCBs, industrial  chemicals)  and inorganic metals (arsenic,  cadmium,  copper, lead,
mercury, selenium, and zinc). Laboratory analysts also looked for other p
otential  contaminants  in  the  1988  collection  by checking  for  unknown  peaks on  a  gas
chromatograph.  Extrapolation of results to other fish and game  animals may be uncertain.

       In an effort to  assess the body burden of organochlorine compounds in birds, the FWS
analyzed starlings and wings from wild ducks shot or trapped by hunters in the United States from
1965 to 1985.  (Sampling of ducks occurred during the 1965,  1966, 1969, 1972, 1976, 1979, 1981,
1982, 1984 and 1985 hunting seasons; sampling of starlings occurred from 1967 to 1985 at 2 to 3
year intervals.) For ducks, mallard wings were used since this  species  is found throughout the
continental United  States.  Black ducks  from the Atlantic Flyway were also included because
mallards are not abundant there. The starling was chosen because  it is numerous, widely distributed
throughout the continental United States, and an omnivorous feeder.

       Sampling of fish and birds is planned to occur approximately every five years as part of the
Biomonitoring of Environmental Status and Trends Program.   Other bioassessment methods will
also be included in this new program.

              chemical extraction methods are used, which are classified according to the chemical
              analyzed; procedures are included in published journal articles

       Approximate time between sample collection and analysis:  1 year, varies depending upon
              sample collection

       The National Emissions Data System (NEDS) provided source data for the AIRS Facility
Subsystem (see separate entry) and the AIRS Area/Mobile Source Subsystem (currently under
development) for point source and area air emissions, primarily for criteria pollutants. These two
AIRS systems have replaced NEDS. Information on individual point sources was available through
NEDS and is now available through AIRS, including: pollutant type and quantity; emissions control
equipment; estimated percent of emission control efficiency; emission estimation methods used and
emission estimates (for both point and area sources); identification of confidential information;
universal transmercator zone and latitude longitude data; stack data;  ash and sulfur content; and
fuel use data, including fuel type, boiler design, combustor/processing method, and throughput,
operating, and fuel process rates.  Raw data or summary statistics  (e.g., geographic and process-
related summaries of emissions and fuel consumption) were available for individual plants for each
criteria pollutant. Inventories of the total number of plants/points within a state or county were
also available, as well as a ranking of plant emissions within a state or nationally for each criteria
pollutant. Emissions could also be identified by Standard Industrial Classification (SIC)  code and
Source Classification Code (SCC). Responsibility for maintaining the NEDS database was shared
by states, EPA Regional Offices, and EPA's National Air Data Branch (NADB). States submitted
data annually to the Regional Office, which validated the data and sent them  to the NADB for
database updates.

Objectives and Coverage:

       The National Environmental Specimen Bank, one of many projects within the National
Biomonitoring Specimen Bank (NBSB) (see separate entry in Part II) at the National Institute of
Standards and Technology, was established in 1979 as a pilot program to investigate the feasibility
of long-term  storage of environmental  samples.  Well-preserved and documented  samples are
archived for retrospective analysis as analytical techniques improve or as concerns about previously
unidentified pollutants arise.  To date, this pilot project has focused primarily on the establishment
of a human liver bank, the analysis of approximately 20 percent of the archived liver specimens for
selected  organic  and  inorganic  constituents,  and research  related  to specimen  banking.
Approximately 600 liver specimens have been collected since 1980; analysis for trace elements,
organic pesticides, and PCBs have been done on approximately 100 of these samples.  In addition,
NIST has made a comparison of different storage conditions and has developed sampling and
storage protocols for archived specimens.  The existing database  on the stored human  liver
specimens and the unanalyzed liver specimens in the bank offer a number of opportunities,  such
as :  providing baseline environmental data for monitoring pollutant trends over time and among
different sites; providing the opportunity for retrospective analysis of samples from the past; and
evaluating the stability of biological samples during storage.

 Sample Design and Analysis:

       In 1980, liver samples were collected during autopsies performed at three locations: the
 Mayo Clinic in Minneapolis, Minnesota; the King County Medical Examiners Office in Seattle,
 Washington; and the State of Maryland Medical Examiners Office in Baltimore, Maryland. From
 1981-1990, liver samples were obtained from the Seattle, Washington facility; in 1991, samples were
 obtained from the Baltimore, Maryland facility. These facilities work with local universities which
 serve as contractors for EPA and NIST for this project. The three geographic areas were chosen
 to represent the east and west coasts and the central United States. Livers are selected from adults
 18 years of age or older, who did not have a long hospital stay, were not drug users, and were free
 from hepatitis  and the human  immuno-deficiency virus  (HIV).  Thus far, analysis for  trace
 elements, chlorinated pesticides,  and PCBs has included three groups of liver samples collected in
 1980, 1982, and 1984.

       Human liver samples are collected, processed, and stored under conditions that avoid or
 minimize contamination of the specimen or any other changes in specimen chemical composition.
 Non-contaminating materials are used for any contact with the sample (e.g., a titanium-bladed knife
 is used  to avoid contamination  from  environmentally  important  trace  elements  found  in
 conventional cutting instruments; clean, dust-free Teflon surfaces are used for sample preparation).
 Identical (e.g.,  homogeneous) sample aliquots are necessary to allow for  valid comparison of
 analytical techniques and evaluation of the stability of specimens during storage.  A cryogenic
 homogenization procedure using Teflon disk  mills was developed by NIST scientists for this
 purpose. These mills homogenize sample aliquots, with subsampling errors due to nonhomogeneity
 estimated at less than 2 percent.  This procedure minimizes contamination and eliminates the risk
 of potential  changes  in  the sample  associated  with  thawing  and  re-freezing.  After sample
 preparation, the liver specimens are stored in Teflon bags or jars  and frozen in liquid nitrogen at
 the NIST specimen bank facility.  Presently, specimens are banked at -150° C to avoid the physical
 changes noted  at other temperatures and because of the relative maintenance-free,  low  cost
 operation of liquid nitrogen vapor freezers. Information describing the sample and the sampling
 site are recorded and maintained in the National Environmental Specimen Bank database.

       To address the question of storage stability, aliquots of the homogenized liver samples were
 analyzed for various inorganic and organic contaminants, and were  stored under conditions such
 as freeze-dried, room temperature, and  fresh  frozen at -25°, -80°,  or -150° centigrade  (C)  and
 reanalyzed in several years for comparison of storage conditions. Results of chemical analyses and
 physical evidence  of changes  (e.g., color changes, clumping, formation of ice crystals) in the sample
 aliquots were used for comparison purposes.

Objectives and Coverage:

       NHANES, a major data collection system  of the National Center for Health Statistics
(NCHS), is a series of discrete data collection surveys in which randomly selected groups of U.S.
citizens are interviewed and examined to determine their health and nutritional status. The goals
of NHANES are: (1) to estimate the national prevalence of selected diseases and risk factors, (2)
to estimate national  population reference distributions of selected  health parameters,  (3) to
document and investigate reasons for trends in selected diseases and risk factors, (4) to contribute
to the understanding of disease etiology,  and (5)  to investigate the  natural history of selected
diseases.

       NHANES obtains  health data from civilian noninstitutionalized individuals  in locations
throughout the United States (including Alaska and Hawaii); the study specifically includes minority
populations and low-income populations.  Young, old, and minority populations are oversampled
to ensure that the data collected for these  groups are reliable.

       To date, two NHANES surveys have been completed and a third is underway.  (A HANES
survey specifically targeted for Hispanics  (HHANES)  is described separately in Part  I of this
Inventory.)  The data for NHANES I were collected from 1971 to 1975, the data for NHANES II
were collected from 1976 to 1980, and NHANES  IE was begun in 1984 and is expected to be
completed in 1994.

       NHANES has historically been a multi-agency effort.  In addition to NCHS, the following
agencies have participated in NHANES surveys:  the U.S. Environmental Protection  Agency, the
Food and Drug Administration, the Department  of Energy, the National Heart, Lurig, and Blood
Institute, the National Institute for Diabetes, Kidney, and Metabolic Disorders, the National Center
for Environmental Health and Injury Control (NCEHIC), the National Institute of Environmental
Health Sciences, the Centers for Disease Control, the National Institutes of Health, among others.

Summary of Environmental Data:

Media: Human samples (blood, urine)

Classes of compounds: Inorganic compounds (including trace metals), VOCs (NHANES III only),
       semi-VOCs, pesticides, cotinine, erythrocyte protoporphyrin, carboxyhemoglobin (NHANES
       II only), and thiocyanate (NHANES II only)

Type of data available:  Individual data entries  on specific agents; summary  statistics (e.g.,
       geometric and arithmetic means, percent elevated, and percent quantifiable) on specific
       agents

Estimation versus observational data:  All observational data

Sample Design and Analysis:

       NHANES studies are cross-sectional and use a complex, multistage, stratified, probability
cluster sample of households throughout the United States.  Primary  sampling units (PSUs) are
identified, and characterized using a wide range of stratification measures such as age, sex, race,
national origin, education, income, and marital  status.  The number of PSUs  identified and the
number of people examined/interviewed is different for each NHANES. For NHANES I and II,
over 20,000 people were interviewed/examined in 100 and 64 PSUs, respectively.  For NHANES
III, NCHS plans to  interview/examine over 40,000  people in 81 PSUs.

       Physical examinations, diagnostic tests (including blood pressures, electrocardiograms, bone
densities (NHANES III only), dental examinations and spirometry); anthropometric measurements;
laboratory analyses (including blood and urine tests, biochemical analysis of whole blood and serum,
and oral glucose tolerance tests (NHANES II and III only); x-rays (x-rays of the hand and wrist
were taken for NHANES I, x-rays of the cervical and lumbar spine and of the chest were taken in
NHANES II, and no x-rays are planned for NHANES  III); personal interviews; and dietary
interviews are conducted on individuals.  Blood and urine samples are analyzed using standard
analytic and QC/QA procedures. Blood sera from NHANES  II are being saved for later analysis
under NHANES III. In addition, any sera available after protocol analyses were performed under
NHANES II, were  frozen  and stored.  These  sera have been largely depleted by subsequent
biochemical analyses for antigens to infectious agents. NHANES III is storing sera and white blood
cells for future analysis.  Longitudinal followup  interviews  were obtained from the adults in
NHANES I (NHANES I Epidemiologic Followup Study).   A similar  followup is planned for
NHANES III.

       NHANES also provides information on consumption of foods.  These data, in conjunction
with contaminant information, might be used to  estimate intake of certain toxicants.

 Objectives and Coverage:

       The National  Herbicide  Use database,  compiled by Resources for the Future (RFF),
 contains data on herbicide use  in agricultural  crop production throughout the United States.
 Estimates of use for 96 active ingredients on 84 crops in the 48 contiguous states of the United
 States are included in the database.  Data available for each crop include 1987 estimates for the
 number of acres of harvested crop, the average rate of use per acre, the total number of acres
 treated, and the total pounds  of active ingredient used. This information can be aggregated on a
 county, regional (group of counties), state, or national level. Data are used by regulatory officials,
 researchers, environmental groups, and planning agencies to design policies for herbicide monitoring
 in the environment and to evaluate proposed regulatory actions.
Summary of Environmental Data:

Media:  Bulk chemicals

Classes of compounds:  Pesticides

Type of data available:  Individual data entries and summary statistics are available

Sample Design and Analysis:

       Crop acreage estimates were taken from the 1987 Census of Agriculture, and estimates of
herbicide use v/ere taken from publicly available federal and state government reports. Additional
insecticides and fungicides have been added to the database since 1987. This information was
aggregated into summary statistics by scientists at Resources for the Future, Inc., based on surveys
conducted by  the Cooperative Extension Service  of  the  U.S. Department of Agricultu-re and
information obtained from company manufacturers.

                     NATIONAL HUMAN ADIPOSE TISSUE SURVEY
Acronym: NHATS
Sponsoring Agency:  U.S. Environmental Protection Agency (EPA), Office of Toxic Substances
       (OTS)
Contact Person:  Janet Remmers, U.S. EPA, OTS, National Human Monitoring Program, 401 M
       Street SW, Washington, DC 20460, (202) 260-1583
Objectives and Coverage:

       NHATS is maintained by the National Human Monitoring Program for the purpose of
detecting and quantifying the prevalence of toxic organic compounds in the general population.
NHATS data are used to address part of OTS's mandate under the Toxic Substances Control Act
(TSCA).  Baseline levels of chemicals in human adipose tissue specimens collected from autopsied
cadavers  and surgical patients in the continental United States are measured.  This monitoring
program has been used primarily for establishing exposure trends for organochlorine pesticides and
PCBs.  In 1984, additional volatile and semi-volatile organic compounds were included to detect
other potentially toxic compounds that might be entering the environment. This expanded target
list was used in the analysis  of adipose specimens  collected during fiscal year 1982 (FY82).  A
follow-up  study of the  FY82  data  was  also  conducted in  order  to  identify  any  gas
chromatography/mass spectrometry peaks which had not been previously identified. NHATS has
also performed several other one-time special studies, such as for lead and cadmium, and a clinical
study of transformer workers. The program is currently finishing analyses on samples collected in
1987. It is unclear whether the program will continue; no new sampling is planned.

       The significance of this  database is twofold.  Human risk compound comparison with
NHATS data allows EPA to more accurately assess the danger of these compounds to the human
population from environmental sources. Secondly, if future sampling is done, compounds identified
in this study may be selected for inclusion in the  broad scan analysis (see Sample Design and
Analysis) of future NHATs samples.  This would provide EPA with long-term bioaccumulation
information which could be tracked for possible long-term trends.

Summary of Environmental Data:

Media: Human samples

Classes of compounds:  Semi-VOCs, pesticides, PCBs (1970-present); inorganic compounds and
       VOCs (1982); dioxins/furans (1982, 1987)

Type of data available: National and regional (census division) summary statistics are available on
       specific agents on a yearly basis

Estimation versus observational data:  All observational data
                                         1-160

-------
 Sample Design and Analysis:

        Human adipose tissue specimens are collected according to a statistical survey design and
 are representative  of  a cross-section of the  population.   The  sampling frame  consists of
 Metropolitan Statistical Areas (MSAs) of the continental United States, partitioned into 17 strata.
 Approximately 1,000 samples are obtained each fiscal year (for some years, the sample size may be
 much less).  Where MSAs or Standardized Metropolitan Statistical Areas (SMSA) cross stratum
 boundaries, they are divided to fit within the strata. A probability sample of MSAs is selected, with
 the probability proportional to the population size. Rural populations were  not considered in the
 sampling strategy.   A hospital,  medical examiner, or pathologist within each selected MSA is
 designated to participate in the survey. Participants are requested to collect  human adipose tissue
 specimens from autopsied cadavers and surgical patients.  Quotas for sample collection for each
 participant are specified for age group, race group, and sex of donor. The  extent to which these
 samples reflect the prevalence in the general population is unclear. If the tissue is collected from
 a cadaver, the donor should preferably have died suddenly (for example, from a car accident or a
 heart attack).  Cachexic (i.e., physically wasted and  malnourished) patients, victims of pesticide
 poisoning, and patients  institutionalized for long periods  of  time  are excluded.  Samples  are
 composited by region and age-group before analysis, and all samples are sent to the laboratory
 contractor (which changes from year to year).

       Data on organochlorine pesticides and PCBs reported for the NHATS specimens up to the
 FY82 collection are based on packed column gas chromatography/electron capture detector analysis.
 The NHATS specimens collected during FY82 were selected for a broad scan analysis of volatile
 and semi-volatile organic TSCA-related chemicals using high resolution gas chromatography/mass
 spectrometry. Although broad scan analysis provided OTS with an expanded list of potentially toxic
 compounds in  adipose  tissue, a large number  of unidentifiable peaks existed.   Therefore, a
 procedure was subsequently developed to automatically characterize these unidentified peaks based
 on  a forward library search approach. This procedure resulted in the tentative identification of
 many additional compounds, however, a significant  number of peaks were  still unresolved  or
 unidentified  in the gas  chromatography  scan.  As a final choice the traditional reverse  search
 approach was adopted on a larger set of target compounds  that offered  a greater degree  of
 selectivity and sensitivity.  On the set of FY 82 composite samples target compound analysis was
 done using three listings of chemicals selected as being among the most environmentally significant:
 the Superfund Amendments and Reauthorization  Act (SARA) Title III, Section 313 toxic chemical
 listing; the SARA Section 110 listing; and a listing of 16 priority compounds from the unidentified
 peaks study  and targeted by EPA  as chemicals of interest.   Three-hundred  and forty-nine
 compounds were identified from  these listings.

Objectives and Coverage:

       The National Human Milk Monitoring Program contains the results of two studies: the
National Study to Determine Levels, of Chlorinated Hydrocarbon Insecticides in Human  Milk
(conducted in 1975-1976), and a follow-up to this study, The Second National Study to Determine
Levels of Chlorinated Hydrocarbon Insecticides and Polychlorinated Biphenyls in Human  Milk
(conducted in 1976-1978).   The objective of these studies was to estimate the  distribution of
selected organochlorine pesticide and PCB levels in human milk among nursing mothers giving birth
in general care hospitals in the United States.  A total of 1,436 milk samples were collected in the
first study and 1,842 in the follow-up  study  from women residing in urban and  rural areas
throughout the contiguous Unites States  The studies were designed to provide information on the
levels of pesticides and PCBs retained in human milk, the geographic variation in retention, and
the characteristics of nursing mothers (including age, dietary information, race, and number of
children nursed). Data collected are useful in estimating long-term trends in pesticide and PCB
levels in human milk.  However, the degree to which these results can be generalized to the entire
population is limited because of potential selection bias (it was not known whether the subjects who
agreed to participate in the study differed from those who elected not to participated in it.)
 Summary of Environmental Data:

 Media: Human milk samples

 Classes of compounds: Pesticides, PCBs

 Type of data available: Summary statistics are available on specific agents

Sample Design and Analysis:

       General care hospitals (622) were chosen from those that participated in the EPA Second
National Hospitalized Acute Pesticide Poisoning Study and were classified  into  one of five
geographic regions (northeast, southeast, midwest, northwest, southwest). The regions were derived
by grouping ten EPA regions into five. Within each of the regions, general care hospitals with
nursery facilities were stratified and a certain percentage were selected according to number of
births during a calendar year.  Every effort was  made to obtain information  directly from  the
selected individuals (mothers).

       Residue analysis performed at participating laboratories included isolating the fat from the
milk and extracting the chlorinated hydrocarbons from  the fat.  Primary identification and
quantification of the pesticides were performed using a gas chromatograph with an electron capture
detector. During data analysis, standard chi-square tests for homogeneity of proportions were used
to statistically investigate differences in distribution of the residues of each contaminant in mother's
milk by geographic region, race,  age, and number of children nursed.  Differences in residue
concentrations between  urban and rural areas were also examined. Analyses were limited to  the
effects of factors individually rather than jointly;  thus, reported differences with respect to one
factor were not adjusted for the effects of all other factors. Also, because of the small sample sizes
it was not possible to investigate the potential effects of employment in a pesticide related industry
and exposure to pesticides at home or at work.

       Identifiers: Geographic region (northeast, southeast, midwest, northwest, southwest)

Time Coverage:  1974-1978

Sample Characteristics:

       Frequency of sample collection:  Irregular; two studies conducted; mothers participating in
              the studies provided one sample per study

       Regularity of sample collection:  Samples were collected at the same time in each sampling
              period                                                  ,

       Source information: No environmental samples were collected to examine the relationships
              between the mothers' milk samples and environmental concentrations of pesticides
              and PCBs.  However, the results from the second study showed decreases in the
              concentrations  of pesticides and PCBs in mothers milk since the time of the first
              study consistent with the banning or restriction of most of these materials in the
              United States after the first study.

Objectives and Coverage:

       The National Marine Mammal Tissue Bank was initiated in 1990 by NOAA, in conjunction
with NIST, to establish a representative collection of tissues from marine mammals for future
contaminant analyses and documentation of long-term trends in environmental quality.  This project
is one of the many activities of the National Biomonitoring Specimen Bank (see separate entry in
Part II of this Inventory).  The National Marine Mammal Tissue Bank is similar to the Alaskan
Marine Mammal Tissue Archival Project (see separate entry in Part I of this Inventory) except that
it focuses on the continental U.S., whereas the Alaskan project  focuses on Alaskan marine
mammals. Since most marine mammals are at or near the top of the food chain, chemical analysis
of their tissues may be useful in determining whether bioaccumulation of contaminants associated
with human industrial activities is occurring in the marine food chains. To date, only tissue samples
from marine mammals in the Northeast have been collected for inclusion in the National Marine
Mammal Tissue  Bank. These include blubber and liver tissue samples from harbor  porpoises
caught in nets by  commercial fisheries and  from pilot whales  stranded on Cape Cod in
Massachusetts.  Samples have been taken from a total of 14 of these animals to date.  Plans  for
future  sampling  include tissue collection of marine  mammals from  all coastal  regions  of the
continental U.S.

       Detailed information was not available at the time of publication.

       Boulevard,  Suite 311, Lakewood, CO 80228, (303) 989-2667
Objectives and Coverage:

       NPSEDMS is maintained by the National Park Service (NPS) for the purpose of assessing
the effects of air pollution on vegetation in U.S. National Parks, primarily those designated as Class
I ("Clean Air" areas).

       This database consists of air sampling results for criteria pollutants within these parks.
Utilizing these results, the NPS seeks to: assess the effects of air pollution on sensitive resources
in these parks; understand the nature and sources of air pollution; assess  the effects of emission
control strategies to mitigate or eliminate the impact of existing and proposed emission sources on
NPS resources; and provide NPS personnel with the information needed to comply with statutory
resource management and protection responsibilities and  to  support  other air quality  related
management needs.

 Sample Design and Analysis:

       National Parks with 6,000 acres of land or greater are selected for inclusion in this program
 based on their Clean Air Act class designation (class I parks are included), as well as ecoregion
 representation and expected range of pollutant concentration.

       A site visit is made at each park to determine appropriate sample locations, which include
 cleared areas with electric power and a telephone system nearby, if possible.  Other sites may be
 selected for  special sampling  projects designed to determine damage to a particular plant life.
 Time-integrated air samples for sulfur dioxide (two 24-hour samples  each week of the year) are
 collected on  filter packs. If elevated concentrations are detected on a frequent basis,  monitoring
 of sulfur dioxide is conducted 24 hours/day throughout the year, using continuous  monitoring
 methods (pulsed fluorescence  spectroscopy).

       Air sampling for ozone is conducted 24 hours/day throughout the year, using  continuous
 chemiluminescence (ultraviolet absorption photometry) monitors, at all sites except Steam Town
 National Historical Site, Scranton, PA.

       Meteorological measurements are also taken at most parks in  the program, with plans for
 these measurements to be taken at all of these parks in the future.

       All air quality and meteorological measurements are reduced to hourly, arithmetic averages,
 except for vector wind speed, which is calculated to a vector average. All averages are reported to
 the EPA Aerometric Information Retrieval System (AIRS) (see separate entry in Part II of this
 Inventory).

                             NATIONAL PESTICIDE SURVEY
Acronym:  NFS
Sponsoring Agency:  U.S. Environmental Protection Agency (EPA), Office of Pesticide Programs
Contact Person:  U.S. EPA, OPP Docket,  Office of Pesticide  Programs, 401 M  Street SW,
        Washington, DC 20460, (800) 426-4791
Objectives and Coverage:

       Primary objectives of the NFS include regulatory, monitoring, and research activities. The
two goals  of this one-time survey are:  (1)  to determine the frequency and concentration of
pesticides and nitrate in drinking water wells nationwide, and (2) to improve EPA's understanding
of how the presence of pesticides and nitrate in drinking water wells is associated with patterns of
pesticide use and the vulnerability of groundwater to contamination.  The program was designed
to obtain information on public community water supply wells and rural domestic drinking water
wells nationwide.  The survey does not assess the presence of pesticides or nitrate at the local,
county, or state levels, nor does it address the presence of pesticides or nitrate in ground water or
surface water generally.  Instead, the survey focused on the quality of water in drinking water wells
before treatment, rather than the quality of drinking water at the tap.
Summary of Environmental Data:

Media: Water (wells ~ municipal and private, before treatment or blending)

Classes of compounds: Pesticides, nitrate, inorganic compounds (127 analytes, total)

Type of data available: Summary statistics on specific agents

Estimation versus observational data: EPA sampled over 1,300 wells; estimated data were used to
       determine pesticide use because actual county-level data were not available
                                          1-173

-------
Sample Design and Analysis:

       The  National Pesticide  Survey  was designed  to yield results  that  are  statistically
representative of the nation's approximately 94,600 community water supply wells and 10,500,000
rural domestic water supply wells.  Stratified random probability sampling methods were used to
select wells for water quality analysis.  EPA sampled 540 community water supply wells in all 50
states  and 752 rural domestic wells in 38  states.   All  counties in the United States  were
characterized according to (a) pesticide use, and (b) the relative vulnerability of ground water to
contamination.  Questionnaires  were used to  collect additional data  describing the well and
surrounding area; well construction; pesticide use on the property where the well was located; and
information on crops, pesticide use, and land use within one-half mile of the well. Chemicals were
chosen that had potential to leach into ground water and which were used in at least one million
pound quantities nationwide in 1982. All pesticides regulated by the Safe Drinking Water Act were
included.

Objectives and Coverage:

       The Superfund Amendments and Reauthorization Act (SARA) (Public Law 99-499, 1986)
Section 118(k) requires the U.S. EPA Administrator to conduct a national assessment of radon
levels where  people normally live  and work, including educational institutions.  The National
Residential Radon Survey provides an estimate of the national frequency  distribution of annual
average radon concentrations in occupied residences (97.5% of the 1980 United States population)
for each of the 10  EPA  regions.  The survey was  designed  to achieve reasonable  precision in
estimating the number of homes with relatively high levels of radon concentration (above 10 pCi/L).
The survey is also intended to provide information from which correlations can be made between
radon concentrations, house construction, and heating, ventilation, and air  conditioning (HVAC)
characteristics.  In addition, the survey is designed to provide information on radon exposures to
sensitive populations, such as children and smokers.

-------
 Sample Design and Analysis:

       NRRS was divided into two phases.  Phase  I  of the  survey involved identifying  the
 households to be sampled, interviewing the residents of each household, and placing the detectors.
 Phase II included panel  maintenance,  collection  of  the  detectors,  analysis  of the  data, and
 production of a final report. Houses selected were those that were defined by the United States
 Census as containing household populations, which account for approximately 97.5% of the United
 States population, and those in which permanent residents lived.  The  study did not include
 nonhousehold populations, such as inmates of institutions, military personnel in base housing or on
 ships, or residents  of college dormitories, rooming houses, convents, or halfway houses.  Following
 administration of the survey questionnaire, year-long alpha-track detectors (ATDs) were placed in
 the participating residences.  Detectors were placed at each level of the home used as living areas,
 other than the basement.  Single-level homes received one  detector in the living area and one in
 the bedroom area. Multi-level homes received a maximum of 3 detectors.  A total of 7,134 homes
 were selected for the survey,  based on statistical and geographical coverage.  After  panel
 maintenance, 6,285 (88 percent of Phase I) homes remained for Phase II — well above the target
 value of 5,000 homes required to meet the survey precision.  The detectors were retrieved through
 the mail  during the summer of 1990. The ATDs were analyzed, and statistical analyses performed

Objectives and Coverage:

       The National  Shellfish Register is a  compilation of information about estuaries in the
United States that have been classified for shellfishing.  To protect public health, approximately 19
million acres in 24 states  are  currently classified as either approved, conditionally approved,
restricted, or prohibited for shellfishing (for oysters, clams, and mussels). First published in 1966,
the Register was developed to inventory-acreage and classification status of shellfishing waters; later
versions have also included information on water quality (based primarily on fecal coliform levels).
The latest (1990) Register includes  historical trends data; information on pollution sources
(including  point and  nonpoint sources),  productivity of waters, and state management efforts;
reasons for changes from the 1985 classifications; and discussions of relationships between shellfish
production, classifications, pollution, and public expenditures.  The Register is  updated every 5
years,  and data are being digitized using NOAA's Geocoast Geographic Information System
(GEOCOAST), which will store data, perform calculations, and print data onto nautical charts.

       The development of these data is one of several interrelated  activities of NOAA. A
separate  database is maintained for each of these activities (see the National Status and Trends
Program  and the National Coastal  Pollutant Discharge Inventory (NCPDI) for descriptions of
related NOAA databases).  Each of these databases use the same spatial framework and together
are used  by NOAA for the strategic assessment of the Nation's coastal and oceanic resources.

Summary of Environmental Data:

Media: Surface water (estuaries)

Classes of compounds: Microorganisms, inorganic compounds, pesticides, PCBs, radionuclides; also
       meteorological and hydrographic data

Type of data available: Individual data entries on specific agents

Estimation versus observational data:  All observational data
                                          1-181

-------
Sample Design and Analysis:

       The Register uses NOAA's National Estuarine Inventory (NEI), which was  created to
provide a spatial framework that could be used in several related NOAA projects.  The spatial
framework developed was the estuarine drainage area (EDA), defined by NOAA as that portion
of a watershed that most directly affects an estuary and is delineated by U.S. Geological Survey
(USGS) cataloging units and the head of the tide. Two atlas volumes were subsequently published
detailing the land use and physical and hydrologic characteristics  of the estuarine systems within
the NEI.

       Sampling requirements and procedures for the Register are based on the National Shellfish
Sanitation Program (NSSP) Manual.  The NSSP requires that a sanitary survey be performed before
an area is approved as a source of shellfish harvesting. The sanitary survey identifies and evaluates
all actual and potential sources of pollution; determines the distance of such sources from shellfish-
growing areas; assesses the effectiveness and reliability of sewage treatment systems; ascertains the
presence of poisonous or deleterious substances; and collects and analyzes water samples  from the
growing area, particularly for bacteriological quality. Sample collection should provide a profile of
adverse pollution conditions, reflecting point sources and meteorological,  hydrographic, and
seasonal factors. Sampling is  performed by state regulatory agencies, primarily for total or fecal
coliform.  Sanitary  surveys are reviewed at least annually by the  Food and Drug Administration
(FDA) and are reevaluated every 3 years.  "Hot  spots," such  as industrial discharge areas, are
sampled routinely.  For the 1990 Register, NOAA examined  state data and/or conducted field
investigations with state personnel for waters in over 100 estuaries.

     NATIONAL STATUS AND TRENDS FOR MARINE ENVIRONMENTAL QUALITY
Acronym:  NS&T

       (ORCA)
Contact Person:  Thomas O'Connor, NOAA (OMA32), ORCA, Coastal Monitoring Bioeffects
       Assessment Division, 6001  Executive Boulevard, Rockville, MD 20852, (301) 443-8644
Objectives and Coverage:

       The  purpose  of the  NS&T  Program is nationwide  monitoring  to  determine the
environmental quality of estuarine and coastal waters and to detect any spacial or temporal changes.
The principal  objectives of the NS&T database are  to: 1) maintain and manage all chemical
concentrations reported from NS&T monitoring programs for marine organisms  and sediments; 2)
provide data to other NOAA personnel for analysis; and 3) provide data to major data centers for
permanent storage.  NOAA coordinates its NS&T program with the Near Coastal component of
EPA's Environmental Monitoring  and Assessment Program (EMAP) (see separate  entry for
EMAP).

       NS&T contains seven  major components: the  Mussel Watch Project;  the Benthic
Surveillance Project; Biological Effects Surveys and Research; Historical Trends Assessment;
Specimen Banking; Regional Assessments; and a Quality Assurance Program. The Mussel Watch
Project monitors chemical levels in bivalve mollusks (mussels and oysters) and sediments.  The
Benthic Surveillance Project monitors chemicals in benthic (bottom-dwelling)  fish and associated
sediments; frequency of external and internal disease conditions in fish is documented. Biological
Effects Surveys are two- to three-year studies conducted in specific locations after previous studies
have indicated potential for substantial environmental degradation. These studies are designed to
provide detailed information of the magnitude and extent of ecosystem degradation.  Biological
effects research  has been conducted in Boston Harbor, southern California, Tampa Bay, Long
Island Sound, and the Hudson-Raritan Estuary; liver tumors, impaired reproduction, or genetic
toxicity in fish resulting from exposure to chemical contaminants have been studied in these areas.

       The Historical Trends Assessment  project combines new and  historical data to provide
information about the evolution of environmental contamination, generally focusing on areas of
highest contamination of specific chemicals; fish, shellfish,  and sediment data have been added to
provide information on long-term chemical contamination trends.  The Environmental Specimen
Banking Project  (see separate entry for the National Biomonitoring  Specimen Bank in Part II of
this Inventory) maintains a specimen bank at the National Institute of Standards and Technology
in Gaithersburg, MD, for future uses (e.g., testing of chemicals that have not yet been identified
as toxic; use of new analytical methods). The Regional Assessment project seeks to compare local
levels of contamination to national-scale results.  Finally,  the Quality Assurance project seeks to
produce nationally uniform analytical results and to ensure comparability among data sets. All

participating labbratories'must use standard procedures and standard reference materials, and must
perform routine tests to check reliability of techniques against both known and unknown chemical
samples.

       The development  of these data is one of several interrelated activities  of NOAA.   A
separate database is maintained for each of these activities (see the National Shellfish Register of
Classified Estuarine Waters and the National Coastal Pollutant Discharge Inventory (NCPDI) for
descriptions of related NOAA. databases). Each of these databases use the same spatial framework
and together are used by NOAA  for the strategic assessment of the Nation's coastal and oceanic
resources.

Summary of Environmental Data:

Media:  Fish/shellfish (mussels and oysters, bottom-dwelling fish); marine sediments

Classes  of compounds: Inorganic compounds;  semi-VOCs; pesticides; PCBs; radionuclides

Type of data available: Individual data entries on specific agents

Estimated versus observational data:  All observational data

Sample Design and Analysis:

       NS&T uses NOAA's National Estuarine Inventory (NEI) (see separate entry), which was
created to provide a spatial framework that could be used in several related NOAA projects.  The
spatial framework developed was  the estuarine drainage area (EDA), defined by NOAA as that
portion of a watershed that most  directly affects an estuary  and is delineated by U.S. Geological
Survey (USGS) cataloging units and  the head of the tide. Two  atlas volumes were subsequently
published detailing the land use and physical and hydrologic characteristics of the estuarine systems
within the NEI.

       NS&T sampling includes approximately 300 sites from near-coastal and estuarine waters.
Sites are located in all states, including Alaska and Hawaii. Monitoring sites are selected 10 to 100
km apart to collect data representative  of large  areas.  Sites are  regularly moved within areas,
although sampling strategy does not change.  Distances between  sites are less in estuaries and
embayments than along open stretches of coast.  The site selection method is designed to avoid
small-scale patches  of contamination. A uniform set of environmental measurements is applied
nationally.  Information on source of pollutants is not determinable through the  database.   The
NS&T Program  includes urban, suburban, and rural areas,  and avoids "hot spots" and/or known
discharge points. Biological effects  studies  are conducted in areas that have moderate  to high
contamination levels.

       In the Mussel Watch Project, six separate composites from each site (three for  organic
compounds and three  for metal  analyses) are collected.   Each mussel composite  contains 30
individuals, each oyster composite contains 20  individuals, and each sediment sample is made of
three composites.  For most  contaminants, bivalves accumulate chemicals  at different rates;
therefore comparisons of biological data from different sites should always account for species type.
Comparisons among sites can  also be made  for sediment samples.  In the Benthic Surveillance

                                          1-186

-------
Project, chemical analyses are generally done on three composite samples of 10-20 fish livers each.
Sixty individuals are analyzed for microscopic changes caused by disease.  Nationwide, 15 different
fish species  are analyzed,  with different species  sampled at different sites.  For the Specimen
Banking project, approximately 10 percent of samples collected at NS&T sites are stored in liquid
nitrogen at the National Institute of Science and Technology.  The Historical Trends Assessments
Project focuses on two types of trends: those involving a single contaminant or contaminant class,
and those involving a number of contaminants at a specific geographical region over different time
periods.  Chemical trends in the sediment cores can be examined through 5 to 10 year intervals.

Objectives and Coverage:

       The National Stream Survey (NSS) was a component of the National Surface Water Survey,
which also included the Eastern and Western Lake Surveys (see separate entries for these databases
elsewhere in this Inventory). The NSS covered surface waters in the mid-Atlantic and southeastern
United States. Its objectives were to 1) determine the percentage, extent, location, and chemical
characteristics of streams that were acidic or that had low acid neutralizing capacity (ANC) and thus
might become acidic in the future; and 2) identify streams representative of important classes that
might be selected for more intensive study or long-term monitoring.  The NSS contains chemistry
data, geographic attributes,  and watershed descriptive information.

Sample Design and Analysis:

       The NSS was designed to chemically  and physically characterize a target population of
streams in the mid-Atlantic and southeastern United States based on a probability sample. For the
purposes of the NSS, streams were defined as water bodies that have drainage areas of less than
155 square kilometers (60 square miles), but are large enough to-be represented as blue lines on
l:250,000-scale  U.S. Geological Survey (USGS) topographic maps.  This size was viewed as a
reasonable compromise that includes streams large enough to be important for fish habitat, yet still
small enough to be susceptible to the impacts of acidic deposition.  During the spring of 1986, the
NSS sampled stream  segments (corresponding to river reaches)  of a  stream network at both
upstream and downstream locations.

       A two-stage statistical sampling procedure was developed to select a representative subset
of 500 stream reaches as a probability  sample from which the characteristics  of the total reach
population could be extrapolated.  Reaches were excluded if they  were  too large, located within
metropolitan  areas or tidal zones, or affected by oil field brine, acid  mine  drainage, or point source
pollution.  The NSS used index values  to  describe the chemical status  of each stream sampled.
Users of the NSS can readily examine subpopulations of interest.  The NSS also includes results
of a pilot stream survey conducted in the southern Blue Ridge Province.

 Objectives and Coverage:

       Anticipation of new federal regulations for air toxics has placed added emphasis  on the
 measurement of volatile organic compounds (VOCs) in most states.  Consequently, knowledge
 concerning ambient atmospheric concentrations of VOCs has advanced considerably in the last
 decade.  A national ambient VOC database covering th'e period from 1970 to 1980 (Brodzinsky and
 Singh, 1983) was previously prepared for EPA.  This database has now been updated to include the
 ambient outdoor and indoor VOC measurements collected between 1980 and 1987. Some personal
 VOC monitoring data (e.g., from EPA's VOC Total Exposure Assessment Methodology (TEAM))
 (see separate entry) studies were also  included.  The database was  prepared by collecting,
 evaluating, and consolidating reports (from researchers and the literature) of ambient and  indoor
 VOC concentrations in urban, rural, remote, source-dominated, and indoor environments; it covers
 more than 300 potentially hazardous VOCs.  All available data were included and given a quality
 rating.   Nevertheless, the original  references  should  be consulted  to obtain  more detailed
 information before using the  database for specific applications.

       The database, which is  in dBase  III+, is organized into 7 files:   ambient daily average
 concentrations, indoor daily average concentrations, sampling and analysis methods, sampling site
 information, bibliographic data  reference, chemical-specific and unit  conversion information, and
 a file containing lists of synonyms of and chemicals  related to, the VOCs in the database.  The
 database is designed to be used with dBbase  III+, which permits efficient linking of files and key
 fields such as data reference,  site type,  and chemical name.

       The primary and secondary objectives  of  this exposure  database are  research  and
 monitoring, respectively.  The database can be used to:  preliminarily compare air quality in urban,
 non-urban, source-dominated, and indoor environments; highlight areas of adequate and inadequate
 information;  and provide a  foundation  for evaluating the implications of state and federal
 regulations.

       Even though within the database the data are reported to three significant digits in ppv, this
 does not mean that all data are accurate to the ppt levels. Conversion of concentrations from ^g/m3
to ppb and different analytical techniques resulted in concentration values reported to three decimal
places. Other limitations of the database include assumptions made in filling in less-than-detectable
concentrations; combining multiple observations taken during a given day; and pooling results from
                                          1-195

-------
widely different sites, and different sampling and analysis protocols.  These and other limitations
must be kept in mind when using the database, which is primarily intended as a screening tool.

Summary of Environmental  Data:

Media: Air

Classes of compounds: VOCs

Type of data available: Individual samples are entered into the database; individual data entries
       are available on specific agents

Estimation versus observational data:  All observational data

Sample Design and Analysis:

       The data assembled in this project came from many different studies with a wide variety of
objectives, sampling time and methods, and analytical techniques.  The 1980s VOCs Database,
published in 1983, contained data collected from 1970 to 1980 and was created under a previous
EPA contract. In updating this database, data published prior to 1980 were not specifically sought,
but were included in the  1987 database when discovered.

       Data were sought by sending surveys to numerous  individuals and by contacting researchers
by telephone. In addition, a computerized literature  search was conducted using the Chemical
Abstracts Service Registry Number (CASRN) database accessed through the DIALOG Information
Retrieval Service; this yielded 3,000 references.  The titles of these references were reviewed and
rejected if they indicated:  (1) a study of emissions or sources; (2) a solely health-related study; (3)
a laboratory or modeling study; or (4)  an industrial workplace study. Thus of the original  3,000
references, 710 were determined to be potentially eligible for inclusion in the update. As many of
these references as possible  were located and reviewed.  The database compilers actively sought
only the 151 VOCs targeted  in the 1980 database.  However, data about other eligible VOCs that
were sampled with the 151 targeted chemicals were also extracted. This increased the number of
chemicals to 320.  Chemicals that were eligible for  inclusion were non-pesticides with vapor
pressures greater than 10-6 Torr at  20 °C known to exist predominantly in the gas phase, not the
particle phase. '

       Data were collected primarily in the United States.  (A very limited amount of data from
Canadian sites were included in the 1980 database.)  Data were sought from both indoor and
outdoor environments; indoor concentrations were limited to either residential or office spaces,
while outdoor spaces were limited to the fenceline and beyond.  The vast majority of the data are
surface measurements of ambient VOCs.  The database includes some aircraft samples taken from
the troposphere, but not from the stratosphere (10 to 50 km).  When more than one sample was
taken per day, daily average concentrations were calculated through a weighting scheme in which
weights were assigned in proportion to the length of the  sampling periods.

       Within the database, the data are ranked and rated. In the 1980 VOCs database, a one-digit
quality code was  assigned  as  follows:  1 for  excellent,  2 for good,  3 for acceptable, 4  for
questionable, and Z when a quality code could not be assigned.  However, the assignment of these

                                          1-196

-------
 quality codes was subjective.  The authors integrated the available published and unpublished
 information with their personal knowledge and experience to arrive at quality codes for the data.
 In the updated database, these codes were left intact for the existing records. For new records,
 however, a new and more objective ranking/rating system using composite scores was developed in
 which scores of 2.0 to 2.3, 2.3 to 2.9,  3.0 to 3.6, and more than 3.6 to 5.0 indicate satisfactory,
 average, good, and very good data quality, respectively.  A score of less than 2 indicates that a
 quality code could not be assigned.

        Users  should  consult the  original references  to obtain more detailed information and to
 assess the applicability of the rating and ranking scheme to their requirements before using the
 ranking and rating  scores.

Quality Assurance/Quality Control Procedures: When the 1980 database was updated, data records
       from 28 randomly selected references (20 percent of the references from which data were
       extracted) were examined and'checked for data extraction and input errors; virtually none
       were found. To ensure accuracy in the entry of new data, the following quality assurance
       procedures were used:  only experienced data entry personnel were used; they worked short
       periods of time each day to avoid errors induced by fatigue and boredom; much of the data
       were transferred into  the database directly from diskettes or magnetic tape (data were
       checked to ensure accurate transfer); error-checking routines were included in the  dBase
       Ill-f software package; all data entries were checked independently to identify errors;
       scatterplots  and other graphic  display  techniques  were used to  identify "outliers"  or
       potentially erroneous data; data outliers were rechecked to ensure that the information was
       correct; and a  number of EPA staff members  and scientists reviewed the project for
       accuracy and consistency of data evaluation and reporting.

Objectives and Coverage:

       USGS's National Water Quality Networks include the National Stream Quality Accounting
Network (NASQUAN),  the National Hydrologic  Benchmark Network, the  Radiochemical
Surveillance Network, and the Tritium Network. The primary objective of NASQUAN, the largest
of these networks, is to detect water quality conditions and trends over time in surface waters, and
when possible to relate trends to upstream land and water use.  A secondary objective  is the
estimation of constituent loads from the continent to coastal areas and the Great Lakes.  In
addition, information on the transport of constituents by rivers to the ocean is available through
NASQUAN.   Users  can generate maps containing information of  interest.  Each NASQUAN
station represents an integration of upstream water quality conditions, and therefore may not
identify specific water quality conditions in other areas of the watershed.

       The Radiochemical  Surveillance Network operates  at selected sites within NASQUAN;
samples are taken for gross radiochemical data for several isotopes. NASQUAN data are used by
state  agencies  to  write  federally  mandated reports  and by  other government and private
organizations for research.

       The Benchmark Network monitors natural streamflow and water quality of small river basins
known to be relatively unaffected by human activity. The objectives of the Benchmark Network are
to document  natural changes in hydrologic characteristics and to provide a comparative base for
studying the effects of human activity on the hydrologic environment. Data from the Benchmark
Network are used to  detect water quality trends and to describe water quality conditions.

       The Tritium Network monitors tritium concentrations in precipitation and streamflow at
network stations. Detectable levels of tritium in the environment are used as a tracer to study the
movement and mixing of water in the hydrosphere.  Data from this network are used to study
deposition and outflow of tritium for the continental United States  and to approximate average
residence times of water within river basins.  Tritium data are best  used to study processes  that
occur on a timescale  of 10 to 100 years.

 Summary of Environmental Data:

 Media: Surface water

 Classes of compounds: Inorganic compounds; microorganisms; physical and chemical indicators of
       water  quality; ions  (including  fluoride)  (NASQUAN  and  Benchmark Networks);
       radiochemicals (Radiochemical and Tritium Networks)

 Type of data  available:  Individual data entries on specific agents at  specific locations; some
       summaries of data are available

 Estimation versus observational data:
       NASQUAN and Benchmark Networks: All observational data
       Tritium Network: Observational and estimated data

 Sample Design and Analysis:

       NASQUAN and Benchmark Network  monitoring stations cover the entire United States
 (NASQUAN covers the continental United States, Hawaii, Alaska, and Puerto Rico; Benchmark
 includes the same except for Puerto Rico).  NASQUAN currently includes 410 sites.  These are
 generally  selected near the  downstream end of hydrologic units known as accounting units
 (established by the Water Resource Council) or at representative sites along coastal areas and the
 Great Lakes.  (Accounting units are part of a standardized system to identify locations of water
 bodies based on hydrologic features, similar to the river reach system.) NASQUAN site selection
 allows for sampling of large rivers and major tributary streams  for  physical  and  chemical
 characteristics, and covers more than 90 percent of the surface water volume in the United States.
 Currently there are approximately 525 accounting units that range in size from 200 to 600 square
 miles. Sampling is conducted at a fixed location on a fixed schedule for each site. Hydrologic units
 include urban, suburban, and rural/agricultural areas.

       The Radiochemical Network consists of 46  sampling  sites within  NASQUAN.   The
 Benchmark Network consists of 58 sampling sites generally located in national or state forests, other
 reserve areas, or on private land. The Tritium Network includes 30 sampling sites (14 streamflow
 and 16 atmospheric precipitation sites) in approximately 11 states (previously, the Tritium Network
was nationwide; data are available for these inactive sites). For years when no data were available
 at a given station, tritium deposition was estimated based on available data from other  locations
 (e.g.,  Canadian and.other sites operated worldwide by the International Atomic Energy Agency
 (IAEA)).  Accuracy of most tritium samples are within 3 percent.

                  NONOCCUPATIONAL PESTICIDE EXPOSURE STUDY
Acronym:  NOPES
Sponsoring Agency:  U.S. Environmental Protection Agency (EPA), Atmospheric Research and
       Exposure Assessment Laboratory, Office of Research and Development
Contact Person: Andrew E. Bond, U.S. EPA, Atmospheric Research and Exposure Assessment
       Laboratory (AREAL), MD-76, Research Triangle Park, NC 27711, (919) 541-4329
Objectives and Coverage:

       EPA's Office of Research and Development (ORD)  and Office of Pesticide Programs
(OPP) conducted the Nonoccupational Pesticide Exposure Study (NOPES) to assess the level of
pesticide exposure experienced by the general U.S. population. NOPES utilized the Total Exposure
Assessment Methodology (TEAM) to estimate exposure.  (See also Volatile Organic Compound
TEAM (VOC TEAM), Particle TEAM (PTEAM), and Carbon Monoxide TEAM (CO TEAM)).
The TEAM approach applies probabilistic population sampling techniques; indoor, outdoor, and
personal exposure monitoring; and human activity pattern data for multiple routes of exposure to
support total human  exposure assessment.   NOPES carried this process one  step further  by
estimating potential human health effects associated with nonoccupational exposures to pesticides
by selected study areas and associated monitoring seasons.  The primary methodological objective
of NOPES was to develop and refine the monitoring instrumentation, laboratory  procedures, and
survey questionnaires needed for a TEAM study of pesticides. The overall analytical objective of
NOPES was to estimate the levels of nonoccupational exposure to selected household pesticides
through air, drinking water,  food, and dermal contact.  Specific objectives were  to: 1) estimate
exposure levels for the populations of two urban areas of the United States; 2) assess the relative
importance of  each exposure pathway  to the  overall level of exposure;  3)  characterize  the
components of variability in the observed exposure levels; and 4) investigate and, if possible, model
the relationships between exposure levels; rates of use, activity patterns, and other factors that could
contribute to variation in exposure levels.


Summary of Environmental  Data

Media: Air, water, food sources, dermal contact

Classes of compounds: Pesticides

Types of data available: Individual data entries and summary statistics on specific agents
                                                                     /
Estimation versus observational data:  Air, water, and dermal contact pesticide concentrations were
       measured directly; food exposures were estimated indirectly
                                          1-207

-------
Sample Design and Analysis:

       The NOPES project was designed to test whether the TEAM approach could be adapted
to estimate exposures to selected household pesticides and pesticide degradation products from air,
drinking water, food, and dermal contact in stratified random samples of the populations in two
urban areas, Jacksonville, FL and Springfield and Chicopee, MA.  Jacksonville was selected to
represent an area of the country with relatively high pesticide use, and the Springfield region was
selected to represent an area of low-to-moderate pesticide use. The Springfield area was broadened
to include the neighboring town of Chicopee to increase the variety of housing types and ensure
a sufficient population size for screening.  The design also permitted examination of several
components of the variation in pesticide air exposures, including regional differences, seasonal
changes, short-term temporal variations, and interpersonal differences in patterns of use.

       In each  study  area, the target population (i.e., the population from which statistical
inferences were to be made) consisted of individuals at least 16 years of age.  Participants were
selected  at  random  using  standard area household survey sampling techniques.   The NOPES
sampling design is a three-stage design. Probability sampling was used at all stages of selection to
ensure that the sample was statistically representative and to allow valid statistical inferences to be
made from the data. In the first stage of the sampling design, a stratified sample of relatively small
Census-defined geographic areas (blocks or groups of blocks) was randomly selected in each study
area. At the beginning of each season's data collection, a second-stage random sample of housing
units was selected, and the sample households were screened to ascertain characteristics of their
dwellings and residents. The screening  data were used to stratify the sample households into three
categories based on the potential for exposure to pesticides from indoor air  (high, medium, and
low).  The  goal for each season's third-stage sample was to have 50 percent  high-exposure
respondents, 30 percent medium-exposure respondents,  and 20 percent low-exposure respondents.
Attempts were made to contact all persons selected in the third-stage sample for participation in
the monitoring and interview portion of the study.  Third-stage sample  members were randomly
selected, and no more than one person was selected from any one household. The final number
of respondents selected for personal and indoor monitoring was 173 individuals in Jacksonville and
86 individuals in Springfield/Chicopee.  The overall response rates from the third and second stages
combined were 45 percent for Jacksonville and 40 percent for Springfield/Chicopee.

       Methodology was  developed for collecting and analyzing air  samples for 32 selected
pesticides and pesticide degradation products.  Emphasis was placed  on both identifying and
quantitating the target pesticide compounds.  The questionnaires  and monitoring and analysis
procedures were tested in a pilot study conducted in Jacksonville, FL in August and September
1985.

       To permit assessment  of regional  and seasonal variations in exposure levels, the main
NOPES data collection was conducted in three phases: Phase I—summer 1986 in Jacksonville, FL;
Phase  II—spring 1987 in Jacksonville, FL, and  Springfield  and  Chicopee, MA; and  Phase
in—winter 1988 in Jacksonville, FL and Springfield, and Chicopee, MA. In both study areas, some
sample members were asked to participate in all seasons of the study, whereas others were recruited
only for a single season. Monitoring some people in more than one season permitted assessment
of whether the overall differences observed between seasons were due to true seasonal variations
or random sampling variations. Short-term temporal variations were addressed by monitoring some
respondents twice in the same season.

                                          1-208

-------
        For each sample member who agreed to participate in the study, a study questionnaire was
 administered, personal and area air sampling were conducted (two or more fixed-site locations; at
 least one inside and outside of the respondent's home),  and an activity log questionnaire was
 administered at the end of the 24-hour monitoring period.

        In some households drinking water samples (29)  were collected for analyses.   Dermal
 exposure during pesticide application events was also estimated for a small number of respondents
 by analyzing cotton gloves worn during typical application events following the regular monitoring
 period.  Food exposure to pesticides was estimated indirectly  by using residue concentration
 information from the Total Diet Study (see description in  Part I of this Inventory) together with
 dietary intake data, which was collected  for each individual in the survey population.

Objectives and Coverage:

       The objective of the Northeast Regional Oxidant Study (NEROS) was to develop a database
for the evaluation of an EPA regional model of ozone formation, transport, and removal and to
obtain data for the study of oxidant formation and transport in urban plumes  and on a regional
scale.  NEROS was a  special-research field study conducted over one-month periods during the
summers of 1979 and  1980.  The 1979 study focused on the measurement of regional ozone and
precursor patterns and development of data used to evaluate the performance of the model.  The
1980 study focused  on measurements to understand physical and chemical processes of ozone
formation and transport, including:  urban plume  studies in Columbus,  Ohio, and Baltimore,
Maryland; regional plume dispersion and chemical studies; and ozone dry deposition and boundary
layer structure measurements over forests and crop lands.  NEROS included the northeastern
portion of the United States, encompassing the area east of about 84° longitude and north of 38°
latitude.  NEROS was coordinated with a separate but related project called Persistent Elevated
Pollution Episodes (PEPE).  An extensive database was generated, called the General Distribution
Database (GDDB) of PEPE-NEROS.
Summary of Environmental Data:

 Sample Design and Analysis:

        NEROS was a large field measurements program  sponsored by the EPA Atmospheric
 Sciences Research Laboratory,  other federal agencies (NASA, the Department of Energy,  the
 National Oceanic and Atmospheric Administration, the Federal Aviation Agency, the Tennessee
 Valley Authority, and the National Science Foundation), industry, and universities in 1979 and 1980.
 Chemical,  optical, and meteorological  measurements were made from stationary and mobile
 platforms and included airborne and ground-based sampling and both in-situ and remote-sensing
 sampling.  A Lagrangian sampling mode was used (i.e., an initial specified volume of air was
 sampled at several forecast positions as it was being transported over the study area). The sampling
 design provided three-dimensional validation data for a regional air model extending from eastern
 Ohio to the East Coast, and from northern Virginia to southern Maine.

        In August,  1979, a regional-scale aircraft sampling program  was conducted using three
 aircraft to obtain: continuous measurements of ozone, oxides of nitrogen, and sulfur dioxide; grab
 samples to be analyzed later for hydrocarbon species; scattering coefficient by nephelometer; and
 meteorological data. Aircraft flew alternately within the mixing layer and above it.  Meteorological
 data were used to establish the orientation and spacing of the flight tracks.  Surface deposition rates
 and cloud venting of boundary-layer ozone were also studied near Lancaster, PA.

        The 1980  field program  was  conducted jointly with the Persistent Elevated Pollution
 Episodes (PEPE) program, which studied regional haze episodes.   For the Columbus, Ohio,
 component of the 1980 NEROS study, three principal chemical  sampling aircraft were used which
 were equipped to make continuous measurements of trace gases (O3, NO/NO,, and SO2) and to
 sample  for aerosols (e.g., particulate  sulfur, sulfuric acid) and meteorological and navigational
 parameters. Each aircraft also collected integrated filter samples, which were analyzed for sulfate,
 nitrate,  and other species. In addition, whole air grab sample canisters  were taken for detailed
 hydrocarbon   speciation.    Other  aircraft  were  used  for  fast-response  and  regional-scale
 measurements (e.g., remote-sensing in long-range flights, both outside the mixing layer and looking
 down into the mixing layer; vertical ozone profiles; and aerosol and ozone spatial distribution. The
 regional-scale transport data were conducted primarily over forests and croplands because these
 areas composed most of the study area  and also to obtain uniformity of terrain offered by rural
 areas (urban areas have many confounding factors) and to study removal of pollutants by forests
 and croplands.  The Canadian Atmospheric Environment Service also took aircraft measurements,
 filter samples at three sites, and meteorological soundings along  the United States-Ontario border.

       In addition to aircraft measurements, ground measurements in the 1980 Columbus, Ohio,
 study were taken at fixed sites for air quality parameters, such as ozone, NO/NO,,, hydrocarbon
 species, aldehydes, and meteorological  data.  Vertical ozone  profiles above the ground were
 measured by a tethered balloon. Two mobile ground platforms also measured a variety of  air
 quality parameters (gaseous and aerosol, including detailed aerosol size distribution); other mobile
 units made meteorological measurements.

       The 1980  NEROS study also  included the Baltimore,  Maryland area for which in-situ
pollutant and meteorological measurements were made using three aircraft and a mobile van  on
22 days  from July to August.  Other pollutant measurements were made from ground stations and

Sample Design and Analysis:  .

       Certain municipalities, national estuary programs, ocean dumping programs, and other
National Pollutant Discharge Elimination System (NPDES) permit holders are required to submit
various types of marine monitoring data as part of their permits.  Sampling strategy is typically
based on the characterization of a point source of pollution (e.g., sewage treatment plant).  If
certain effluent limitations are not met by a wastewater treatment facility, additional monitoring
could be required. ODES can store and analyze data. Information in ODES is accessed through
a series of analytical tools that performs retrieval or analysis (e.g., scatterplots, bar charts, maps,
or reports).  ODES includes over 2 million entries with the majority of the data being from
southern California.

         PARTICLE TOTAL EXPOSURE ASSESSMENT METHODOLOGY STUDY
Acronym: PTEAM
Sponsoring Agency:  U.S. Environmental Protection Agency (EPA), Atmospheric Research and
       Exposure Assessment Laboratory,  Office of Research and Development; California Air
       Resources Board

       Resources Board, Sacramento, CA (916) 323-1504
Objectives and Coverage:

       The primary objective of the PTEAM was to estimate the frequency distribution of exposure
of an urban population to inhalable and respirable particles. The study attempted to determine the
sources of particle exposures through the combination of mass and chemical measurements made
on personal, indoor, and outdoor particle samples. (See also the Volatile Organic Compound Total
Exposure Assessment Methodology Study (VOC TEAM), the Carbon Monoxide Total Exposure
Assessment Methodology Study (CO TEAM), and the Nonoccupational Pesticide Exposure Study
(NOPES) in Part I of this Inventory.)

       As a  preliminary to the PTEAM population  study, a nine-home prepilot study  was
conducted in  March 1989 in the San Gabriel Valley of Southern California, which includes cities
such as Arcadia,  Temple City, El Monte, Monrovia, Azusa, Covina, and Glendora.  The primary
purpose of this nine-home study was to develop a methodology for personal exposure monitoring
of particulates that could be applied later in the large-scale main population study.  Personal
aerosol monitoring conducted during  this prepilot study included 12-hour measurements over a
period of several days of 2 participants in each of 9 volunteer households, using personal exposure
monitors (PEM). Microenvironmental monitoring (MEM), in which particles were measured in and
near the homes of participants, was also conducted.

       The full-scale field study took place in the fall of 1990. The main goal of the study was to
estimate the frequency  distribution of exposures to PM10 (particulate  matter less than 10 /-im in
aerodynamic  diameter) for  all nonsmoking Riverside residents aged  10 and above, based on a
probability sample of 175 residents.  Several other objectives included: 1) estimating the frequency
distribution of indoor concentrations in residences and immediate outdoor air  (e.g., back yards)
concentrations of fine  (aerodynamic  diameter. < 2.5 /im) and coarse (aerodynamic diameter
between 2.5ju,m and 10 ju.m) fractions of PM10; 2) determining the relationships between indoor,
outdoor, and  personal measurements;  3) using the concurrent indoor and outdoor measurements
to determine  the contribution of outdoor air to indoor and personal concentrations; 4) identifying
activities affecting personal exposures to PM10 using "12-hour recall" questionnaires answered by the
participants;  5) determining the sources of particles using measurements and diary  data; 6)
estimating the contribution of environmental tobacco smoke (ETS) and other particle sources to
                                         1-220

total  particle  exposure;  and 7) confirming the existence  of the "personal cloud" effect, and
identifying its  source, if possible.

Summary of Environmental Data

Media:  Air

Classes of compounds:    Particulates  (PM10  PM^, particle-bound  elements,  particle-bound
       polyaromatic hydrocarbons (PAHs), particle-bound phthalates, nicotine)

Types of data  available:  Individual data entries and summary statistics on specific agents

Estimation versus observational data:  All observational data

Sample Design and Analysis:

       Since the PTEAM Study was a cooperative venture through  an independently funded
research effort supported by the California Air Resources Board (CARB); the study site (Riverside)
was in California. In addition to particle mass and elements, the particle-bound organic compounds
and semi-volatile organic compounds were measured as indicators of potential mutagenicity and
carcinogenicity.  Thus an additional objective was to measure semi-volatile organics  in subgroups
of the southern California  test population.  CARB sponsored the measurement and analyses of
polyaromatic hydrocarbons (PAHs) and phthalates in both indoor and outdoor rnicroenvironmental
samples.

       Riverside, California was selected as the urban area most suitable for performing the
PTEAM study because of the temporal variability of inhalable particulate concentrations and the
absence of a single  dominant stationary  source of pollutants.  A probability sampling design was
used  to select participants in Riverside to provide the basis for interferences to  the  target
population's personal  exposures  to  inhalable particles  (PM10).   A stratified multistage area
household  sampling  design was used because the environmental samples had to be collected in-
person and because face-to-face interviewing were necessary to obtain the highest response rates.
Geographic areas were selected at the first stage of sampling.  At the second stage, brief interviews
were conducted for a sample of housing units within the selected areas to identify the household
members eligible for the PTEAM study.  These data were used by the interviewer to determine
which individual, if any, to select from the household for personal exposure monitoring.  For each
Riverside resident, the overall probability of being  selected was approximately equal, except for
people who worked outside the home at least 30 hours per week and for people who were exposed
to passive smoking in their homes.  The latter subpopulations were slightly oversampled to obtain
sufficient sample sizes to support separate statistical analyses. The survey design resulted in a
sample  of  people  from  which defensible inferences could be made  to  the  target Riverside
population of 139,000.

       In the Riverside PTEAM Study a total of 178 nonsmoking persons aged 10 or older were
selected for monitoring over 2 consecutive 12-hour periods.  During each monitoring period, one
personal, indoor, and outdoor PM10. and one indoor and outdoor PM25 samples were scheduled for
collection.   Approximately 4 persons were  monitored each day. from September 22 through
November  9, 1990.  To provide source characterization data, additional  samples were collected to

                                          1-221

-------
measure nicotine levels and air exchange rates in each study home.  Under direction from the
California Air Resources Board, particle-bound PAH/phthalate samples were collected in a subset
of 135 homes. A fixed monitoring site was set up at one location in Riverside to monitor ambient
levels of particulates during each 12-hour period throughout the study.  Samples for PM10 and
dichotomous samplers were operated at this site alongside personal and stationary monitors
identical to those used for participant monitoring. A mobile laboratory was set up in Riverside for
weighing all particulate filters.

       Over 95 percent of the personal and stationary particulate samples,  nicotine samples, and
air exchange  samples  were successfully  collected  as  scheduled.   Over 90  percent of the
PAH/phthalate samples were  successfully collected.   The only significant  portion of data not
collected as intended was the measurement of meteorological conditions at the monitoring site.
Meteorological data were obtained from three airports in the vicinity of Riverside to supplement
data from the monitoring site.

Objectives and Coverage:

       PIN enables pesticide monitoring data generated by a variety of sources to be routinely
identified, obtained, and utilized.  PIN also provides federal, state, and local agencies with a means
of sharing information  and expertise on pesticides.  In addition, information in PIN is used to
enhance the accuracy of pesticide risk assessments and risk/benefit regulatory decisions regarding
exposure and.effects of pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act
(FIFRA). PIN is composed of three files:

       1) The Pesticide Monitoring Inventory (PMI) is a nationwide compilation of synopses of
pesticide monitoring projects conducted by federal, state, and local governments as well as private
groups.  PMI includes the location of the monitoring project, the pesticide(s) involved, an abstract
of the project, and the name and address of a contact person. PMI does not contain hard data or
results; these can be obtained from individual contact persons for each project.

       2)   The Restricted Use Products  (RUP) File is a regulatory file that serves  as an
information resource  for states.  Information provided includes  pesticide active ingredients, dates
of restriction, reasons for restriction, and all products that contain the restricted active ingredients.

       3)  The Coordination File is a cross-referencing chemical index of all synonyms for the
active ingredients listed in the PMI and RUP files.

       In addition, by 1992, PIN will include a database containing monitoring data from the late
1970s to the  present for pesticides in ground water.   PIN will  also include a  file  on the
environmental  fate of pesticides, including chemical and physical parameters  (e.g., solubility, soil
conditions, pH, half-life, etc); computerized fact sheets on pesticides; and certification and training
data for pesticides.

       Building 051, Upton, NY 11973	


Objectives and Coverage:

       Atmospheric, effluent, and solid waste releases of radioactive materials from nuclear power
plants (planned, existing, or closed) are governed by  10 C.F.R. Parts 20 and 50 and by limits
established in site-specific technical specifications (NRC-approved) for each facility. Through the
Office of Nuclear Reactor Regulation,  the Nuclear Regulatory Commission  (NRC) maintains a
record of radioactive releases  from licensed nuclear reactors to ensure that they are within
regulatory requirements. This database  contains data from licensed nuclear power plants that were
declared by the utilities to be in commercial operation from 1978 onward, and includes facilities
which are permanently or indefinitely shut down or are not yet in commercial operation.
 Summary of Environmental Data:

 Media: Water (liquid effluent); air (emissions); soil (solid waste)

 Classes of compounds: Radionuclides

 Type of data available: Individual  samples are entered into the database; annual summary
        statistics are available in published reports

 Estimation versus observational data:  Observational data for operating facilities; estimated
        data for closed or pre-operational facilities
                                           1-232

-------
 Sample Design and Analysis:

       The sampling strategy is based on radioactive releases reported by licensed nuclear power
 facilities as of December 31st for each year.  Data consist of activity in Curies (both total and by
 nuclide, airborne, liquid, and solid) reported quarterly, semiannually, or annually and presented in
 written reports as  annual  releases.   Generally, quarterly, semiannual, and annual data are all
 contained in the database,  although licensed facilities are only required to report annual releases.
 The database only covers planned releases, which result from normal operation or from anticipated
 operational occurrences. Major unplanned releases — such as accidents — are not included; however,
 unplanned releases or radioactive materials from miscellaneous actions such as equipment failure,
 operator error, or procedure error that are not of such consequence as to be considered accidents
 are included in this database. The release information is used for modeling population dose by the
 Pacific Northwest Laboratory, which combines meteorological  and population information with
 release data for a specified area around each plant.

Objectives and Coverage:

       The  Recall Database  includes vehicle emissions  results  generated  specifically  for
enforcement  purposes.  Selected in-use motor vehicles are subjected to emissions  testing to
determine if they comply with federal emissions  standards.  These data are used in investigations
which may result in a recall of a class of vehicles to correct an emissions  nonconformity.  The
testing is conducted at selected sites to be representative of the national population.
Summary of Environmental Data:

Media:  Air (vehicle emissions)

Classes  of compounds: VOCs (evaporative hydrocarbons); criteria pollutants (carbon monoxide,
       nitrogen oxides)

Type of data available:  Individual data entries and summary statistics are available on specific
       agents

Estimation versus observational data:  All observational data

-------
Sample Design and Analysis:

       The Recall Branch of EPA selects a vehicle class (an engine family, with a subset of similar
vehicles sometimes included) for emissions testing based on previous performance and information
obtained from manufacturers and other sources.  Emissions testing is done at the Motor Vehicles
Laboratory in Ann Arbor, Michigan or the Virginia Testing Laboratory in Washington, DC.  A
certain percentage (dependant upon resources)  of the selected vehicles   are also tested at the
Department of Health, Denver, Colorado, to determine if vehicles comply at high altitudes. Testing
at these sites is considered by the Recall Branch to be representative of the national population,
since there is no significant bias in selection. A randomized list of vehicles in the selected vehicle
class and geographical area(s) is obtained from the state(s) motor vehicle registration office. Based
on a telephone questionnaire administered to owners, a sample of vehicles which have been
properly maintained and used are selected for testing from this list. Emissions testing following the
Federal  test procedure  described  in 40 CFR 86  includes measurements  of  total  exhaust
hydrocarbons, carbon monoxide, and oxides of nitrogen in grams per mile; evaporative hydrocarbon
emission measurements are expressed in grams per test. If an initial surveillance program indicates
possible  noncompliance,  a  confirmatory, testing  program  of the vehicle  class is generally
implemented, which consists of additional emissions testing of properly maintained vehicles.  This
testing procedure employs more stringent vehicle screening criteria. The vehicle class is investigated
whenever elevated emissions are  detected, which results  in a recall of the affected vehicles if a
problem is found.

Objectives and Coverage:

       The  Regional Air Pollution Study (RAPS), conducted from 1974 to 1977, served as a
comprehensive study of an urban area for which all interrelated processes affecting air pollution
emissions, dispersion, composition, and atmospheric effects could be studied concurrently. RAPS
was established with three main objectives: to develop, evaluate, and validate air quality simulation
models on a regional scale, covering urban and rural stationary and mobile sources; to develop,
evaluate, and validate models of local-scale phenomena that complement regional-scale models; and
to create a comprehensive, accurate, and readily retrievable database based on field investigations
for all criteria pollutants and selected non-criteria pollutants that describe atmospheric effects  on
pollutant dispersion  and composition.   This  database was then used to evaluate air  quality
simulation models. Because of the availability of extensive monitoring data associated with RAPS,
additional  independent  research  projects  were conducted  by various  groups  in  the same
geographical area during the same time period.
Summary of Environmental Data:

Media: Air

Classes of compounds: Criteria pollutants (sulfur dioxide, particulates, carbon monoxide, nitrogen
       •oxides, ozone), total hydrocarbons, methane, index of fine particles (scattering coefficient)

Type of data available:  Individual data entries and summary statistics are  available on specific
        agents

Estimation versus observational data:  All observational data
                                           1-241

-------
Sample Design and Analysis:

       RAPS was designed to quantify the effects of air emissions on air quality at the level of an
Air Quality Control Region  (AQCR).  Criteria for selection of a specific AQCR included: a
geographic area isolated enough so that inflows of emissions into the area were not a confounding
factor; an area with heterogeneous types of emissions; an area in which existing pollution control
programs were in place to meet air quality standards; and an area in which climatic conditions were
relatively stable (e.g.,  free of  the  effects  of sea  breeze, no severe  terrain).   The St.  Louis,
Missouri/Illinois area was selected for RAPS from a group of 33 Standard Metropolitan Statistical
Areas with populations greater than 400,000.

       The RAPS field measurement program consisted of: continuous measurements from 25
stations in a Regional Air Monitoring System (RAMS), which provided an extensive database for
model evaluation and development; an emissions data inventory (which included both point and
area source emissions); and meteorological measurements (radiosondes and pibals). RAMS was
designed to provide continuous, surface-based aerometric measurements; stations were located in
concentric circles with average radii from a central urban station of 5, 11, 20, and 44 kilometers.
Stations were concentrated at the  center of the network because a criterion  for site  locations
required minimum spacing where  concentrations and gradients were highest.  Four rural sites were
spaced approximately 90' azimuth and were located to provide background measurements regardless
of wind direction. Concentrations of gaseous pollutants are available as minute average values and
as hourly average values.  Hourly emissions data combined  several .categories of point and area
source  emissions:  river vessels,  fugitive  dust, highways, railroads, stationary residential and
commercial sources,  off-highway mobile sources, stationary industrial  sources,  and airports.
Instrumentation used included: real-time pollutant analyzers to measure ozone, nitrogen oxides,
sulfur gases, and carbon compounds; meteorological sensors; high volume samplers for particulates;
nephelometer and dichotonious samplers; and test/control systems.

       RAPS data were collected prior to issuance of EPA monitoring guidelines for State and
Local Air Monitoring Stations (SLAMS) (see separate entry), but many of the concepts in SLAMS
guidelines were tested in RAPS.

           RESOURCE CONSERVATION RECOVERY INFORMATION SYSTEM
Acronym: RCRIS
Sponsoring Agency:  U.S. Environmental Protection Agency (EPA), Office of Solid Waste and
       Emergency Response
Contact Person: Kevin Phelps, U.S. EPA, Office of Solid Waste and Emergency Response, 401 M
       Street SW, Washington, DC 20460, (202) 260-4697
Objectives and Coverage:

       Under the Resource Conservation  and Recovery Act (RCRA), generators, transporters,
treaters, storers, and disposers of hazardous waste, as defined by the federally recognized hazardous
waste codes, are required to provide information concerning their activities to state environmental
agencies, who in turn provide the information to regional and national U.S. EPA offices.  The
information is used to ensure compliance  with federal  regulations under RCRA.  The primary
objectives of RCRIS (formerly the Hazardous Waste Data Management System — HWDMS) are
to monitor and regulate notification, permit, compliance, and corrective action activities conducted
by hazardous waste facilities across the nation. HWDMS provided this information on a facility
level; by January 1,1992, all states will shift over to the RCRIS program, which provides unit level
data and integrated corrective action information. At that time, HWDMS, for which facility data
only was available, will be archived and will become obsolete; the data will be incorporated into
RCRIS in  a new  format.  The database  was not designed  to provide exposure information;
quantitative monitoring data  are not  included.  RCRIS provides  qualitative information on
hazardous waste facilities that have applied for permits.
Summary of Environmental Data:

Media:  Water, soil, bulk chemicals

Classes  of compounds:   Hazardous waste codes as defined in 40 CFR,  Part  261, subpart D,
       including inorganic compounds; pesticides; VOCs; semi-VOCs; ignitable,
       corrosive, and reactive wastes

Type  of data  available:  Both individual data entries and statistical summaries are  available;
       information is provided for specific sites and types of facilities

Estimation versus observational data: All observational data
                                          1-245

-------
Sample Design and Analysis:

       A hazardous waste facility applies for a permit to store, treat, generate, transport, or dispose
of hazardous waste by notifying the environmental agency in that state.  The state receives and
reviews the permit applications (including conducting on-site inspections), enters the data into the
RCRIS system, and transfers the information to the regional U.S. EPA office. The regional office
conducts its own on-site inspections, compares information with state-supplied data, and resolves
any discrepancies in information.  The data are then transferred  to U.S. EPA's Office of Solid
Waste and Emergency Response, which integrates the data into the RCRIS system. After a permit
for a hazardous waste handler has been approved, the U.S.  EPA Office of Solid Waste and
Emergency Response verifies and updates permit application information by reviewing biannual
reports submitted by facilities and possibly through on-site  inspections  of selected facilities,
particularly if information has changed for a permit.

	93478, Las Vegas, Nevada 89193-3478, (702) 798-2305


Objectives and Coverage:

       STDMS contains noble gas or radionuclide measurements in air, water, animal tissue, and
plants  in areas surrounding  the Nevada test  site  (Nevada, Utah, and California locations).
Measurements include gamma spectrometry, tritium,  strontium,  and plutonium in surface and
ground water; gross beta, tritium, noble gases (krypton, and xenon), and gamma emitters in outdoor
air; and cesium, strontium, and plutonium in blood, bone, and tissue of animals. Sampling of plants
for radionuclides is occasionally done. These data are used as supporting data for the Internal
Radiation Dosimetry  System  (see  separate entry in  this  Inventory) which documents human
radionuclide exposure of families residing in this area. Results from both databases are used to
evaluate the total radiological  dose to the region from the Nevada test site.

Objectives and Coverage:

       SLAMS were established to meet the Clean Air Act requirement that every state create a
network of air monitoring stations for criteria pollutants, using criteria set by OAQPS for their
location and operation.  States  are required to provide  OAQPS with annual summaries of
monitoring results at SLAMS sites, although most states supply this information more frequently
(monthly or quarterly). National Air Monitoring (NAMS) sites, part of the SLAMS network, are
located in areas of high population and high pollution concentration; other SLAMS sites may be
located in other areas.  Also, NAMS sites remain at the same location over time; this may not be
true for other SLAMS sites. All SLAMS monitoring sites meet uniform criteria and follow standard
procedures established by OAQPS for analytical methodology and quality assurance. SLAMS data
comprise  most of the data found in the Air Quality Subsystem (AQS) of  the  Aerometnc
Information Retrieval  System (AIRS) (see separate entries for AQS in Part I and AIRS in Part II
for further information).

                       STATE/EPA RESIDENTIAL RADON SURVEY
Acronym:  None
Sponsoring Agency: U.S. Environmental Protection Agency (EPA), Office of Radiation Programs
Contact Person: Jeffrey Phillips, U.S. EPA, Office of Radiation Programs, 401 M Street SW,
       Washington, DC 20460, (202) 260-4114
Objectives and Coverage:

       The State/EPA Residential Radon Survey is a cooperative effort between regional U.S. EPA
offices and state health departments in an attempt to characterize the extent and magnitude of the
indoor radon (222Rn) problem.  The U.S. EPA provides assistance to the 34 currently participating
states in the selection and testing of a probability-based sample of houses.  Short-term radon
measurements are taken in the lowest liveable area during the heating season for all participating
homes, and during  the other three  seasons in ten percent of the sample homes for long-term
monitoring.  Through the program, individual states are able to characterize the radon distribution
on a statewide basis and for regions within their state. Consequently, states are able to prioritize
the allocation of resources toward radon programs based on a sound assessment of the radon
problem in the state.  Individual homeowners are also provided a basis for determining whether
additional measurements are needed for making mitigation decisions. U.S. EPA recommends that
homeowners perform different types of follow-up measurements for screening readings between 4
pCi/l .(picocuries per liter)  and 20 pCi/1 and for  readings  above 20 pCi/1.

       The  state radon surveys provide direct  estimates of how many houses in the target
population are affected by these action levels. States not included as of 1991: Arkansas, Delaware,
Florida, Illinois, Maryland, Mississippi, Montana,  New Hampshire, New Jersey, New York, South
Dakota,  Oregon,  Texas, Utah, Virginia,  and Washington.  Currently, there is no  relationship
between this survey and EPA's National Residential Radon Survey (NRRS) (see separate entry).
The database results should not be used directly to assess annual averages or health risks because
they represent screening measurements and may overstate annual average concentrations in living
areas.
Summary of Environmental Data:

Media:  Indoor air

Classes  of compounds: Radon

.Type of data available: Radon concentration distributions for a given state

-------
Estimation versus observational data:  Observational data from actual samples

Sample Design and Analysis:

       The survey utilizes short-term, charcoal canister measurement devices that are analyzec
the U.S. EPA laboratory in Montgomery, Alabama.  In addition, long-term  screening devi
designed to measure annual average indoor radon concentrations are placed in a 10% subsamj.
of houses. Screening measurements have been made in over 46,000 randomly selected hous
representing a population of more than 25 million houses. Measurements are made in the lowest
livable area during the heating season in closed-house conditions. For the long-term screening
subsamples, measurements are also taken in the other three seasons.  The target population consists
of owner-occupied, private or main residences with: a) a listed telephone number, b) a permanent
foundation, and c) at least one floor at or below grade level. This target population excludes most
mobile homes, high rise apartments, renters, businesses, and seasonal homes.

       For each state, a probability sample of listed residential telephone numbers was selected
from  a sampling frame constructed from telephone directories for all communities in the state.
Counties suspected of having elevated indoor radon levels and/or having low population density
were  sampled more heavily to ensure good coverage  of all geographic areas in the state and to
enhance the chance of finding areas with elevated radon concentrations. Statistical analyses of the
measurements provide statistically valid results and projections for states and regions within states.

       20460, (202) 260-7030                                 	
Objectives and Coverage:

       STORET was developed as a uniform data collection and reporting system for chemical,
physical, and biological water quality data in the United States, U.S. Territories, and parts of
Canada. STORET can be used to store, retrieve, and analyze data (including trends) for both
surface water (including  effluent) and ground water, and is particularly useful for areas near
discharge sources.  Used in conjunction with the Reach Pollutant Assessment file (see separate
entry), STORET forms the basis for many other water information systems.  The majority of the
data in STORET is from non-EPA sources, including states and other federal agencies (e.g., U.S.
Geological  Survey (USGS),  U.S.  Army Corps  of Engineers, U.S. Forest Service, Bureau of
Reclamation, and the Tennessee Valley Authority).  EPA maintains the database for its users.
STORET is accessible to anyone who wishes to obtain information.  In addition to its monitoring
objectives, STORET is used for regulatory purposes; for example,  EPA uses STORET for its
national water quality analysis program. The primary  component systems within STORET include
the Water Quality System, the Biological System, the Daily Flow System,  and the Fish Kill File.

       The Water Quality System (WQS) is composed of physical and chemical data obtained during
monitoring of waterways.  WQS contains data on sampling collection sites (stations) and on the
samples collected,  including information  on where, when, and how samples were  collected; the
aquifer in which or above which the site is located; parameters tested for; and test results. Ambient
water quality and effluent chemistry information is included. Some data on fish tissue and sediment
are also included.  WQS  can be linked to other water databases, such as BIOS and the  Permit
Compliance System (see separate entry).

       The Biological System (BIOS) contains biological  data on aquatic organisms, including
distribution,  abundance,  physical  condition, and habitat descriptions.  BIOS can incorporate
statistical methodologies  for biological analysis. Information  in BIOS includes  site (station)
collection data  (including location identifiers, hydrology,  site description, and time  of sample
collection); a complete record  of observed biota (e.g.,  taxonomic identity, species counts); and
possibly sampling environment  data (e.g., meteorology, physical and chemical water conditions).
BIOS can be linked to STORET's Water Quality File and to EPA's Permit Compliance System
(PCS).

       STORET's Daify Flow System contains daily observations at U.S. Geological Survey gaging
stations, primarily of stream flow.  It also  includes some water  quality parameters, such as
                                          1-254

-------
 temperature, dissolved oxygen, pH, and chloride. This information can be used for analyzing waste
 load allocations and for other regulatory analyses.

       The Fish Kill File, for which data collection began in 1960  and was discontinued in 1990,
 tracks fish kills in the United States caused by pollution resulting from a variety of human activities
 (i.e.,  industrial, municipal,  agricultural,  transportation).  The purpose of this File is to  obtain
 information on the effects on fish of pollutants discharged to surface waters, and to allow EPA and
 states to  determine  causes  of fish kills.  Data in the File include location, circumstances,  total
 number of fish killed, and number of each species killed.  Other information in the File includes
 primary land use surrounding the  kill site,  causes of the kill, pollutants identified at the site, and
 sources of pollutants. Reporting is voluntary, and therefore it is probable that numerous fish kills
 go unreported.

 Summary of Environmental Data:

 Media:  Water (surface water, ground water); soil (sediment); food sources (fish)

 Classes of compounds:  Inorganic compounds, VOCs,  trihalomethanes, serni-VOCs, pesticides,
       PCBs,  dioxins/furans, radionuclides, ions  (including fluoride), physical  and chemical
       indicators of water quality

 Type of data available:  Individual data entries and summary statistics are available  on specific
       agents

 Estimation versus observational data: All observational data

 Sample Design and Analysis:

       STORET includes 150 million water sample observations from 800,000 sampling sites in all
 50 states from virtually all rivers and waters contiguous to the United States and in U.S. Territories
 (Guam and Puerto Rico) and portions of Canada.  Because the data are collected from different
 organizations, STORET does not have an overall sampling strategy.  The primary source of data
 is monitoring information provided by states; the largest single contributor of data is the  U.S.
 Geological Survey, which transfers data from its WATSTORE system to STORET (USGS water
 quality data are transferred monthly; daily values data are transferred every six months; see separate
 entry for WATSTORE).  Monitoring strategies (e.g., sampling frequency, constituents sampled) are
 established by the collecting  agency. General EPA guidelines for water quality monitoring exist and
 may be followed by some  of the states and other agencies submitting data to STORET, but
 information on individual agency monitoring practices  is not readily available. (Examples of some
 EPA monitoring  guidelines include: Technical Guidance Manual for Performing Waste Load
Allocations; Technical Support Document for Water Quality-Based Toxics Control; Guidelines for the
Preparation of State Water Quality Assessment (305 (b))  Reports; and Assessing Biological Integrity in
Running Waters: A Method and Its Rationale.) Participating groups are identified with unique codes,
 and some  information regarding individual sampling strategy for specified locations can be retrieved
 upon request. New information is submitted daily by users; updates of data files are conducted
weekly.  Information is checked for reasonableness (e.g., that results  for tests fall within the possible
 range) when added to the system, but users are largely free to define the information they submit.
                                           1-255

 Contact Person:  James A. Emanuel, U.S. International Trade  Commission, 500 E Street SW
        Washington, DC 20436, (202) 252-1367


 Objectives and Coverage:

        The Synthetic  Organic Chemicals, United States Production and Sales database consists of
 information collected  annually by the United States International Trade Commission (ITC) on the
 production and sales of each synthetic organic chemical produced in the United States.  Originally
 requested  by the  House Ways and Means  Committee  in 1916,  this information  is a legal
 requirement of  companies and is compiled into annual ITC reports that list summary statistics
 within 15 specified groups of organic chemicals. Statistical comparisons with previous years are
 included. These published reports are provided to various federal agencies and are available to the
 general public upon request.
Summary of Environmental Data:

Media:  Bulk chemicals

Classes  of compounds:  Synthetic organic chemicals  (including VOCs, semi-VOCs, pesticides,
       PCBs, dioxins/furans, acids, bases)

Type of data available:  Summary statistics are available on a large number of organic chemicals

Estimation versus observational data:  All observational data
                                         1-259

-------
Sample Design and Analysis:

       An annual questionnaire, of total output is sent to all known producers of approximately
6000 synthetic  organic chemicals in the United States by the International Trade Commission.
Producers are legally required (under the Tariff Act of 1930) to complete the questionnaire and
return it to the  Commission. The questionnaire separates  organic chemicals into 15 classifications:
coal tar tar crudes and pitches; primary products from petroleum and natural gas for chemical
conversion; cyclic intermediates; dyes; organic pigments; medicinal chemicals; flavor and perfume
materials^ plastics and resin materials; rubber-processing chemicals; elastomers; plasticizers; surface-
active  agents;  pesticides  and related products; miscellaneous  end-use chemicals  and chemical
products; and miscellaneous cyclic and acyclic chemicals.

        Within  each classification, the ITC specifies a minimum reportable quantity based on the
volume of production or sales or value of sales. Data are published so as not to reveal individual
company operations. A disclosure of confidentiality can also be requested by companies so that
company names will not be identified.

 Objectives and Coverage:

        Since 1961, the Total Diet Study (TDS), also known as the Market Basket Study, provides
 yearly estimates of dietary intakes of selected pesticides, industrial chemicals, radidnuclides,  and
 elements or nutrients for the U.S. population.  These intakes are then compared with established
 safe or recommended dietary intake levels. TDS also allows FDA to: identify dietary trends over
 time; observe potential public health problems; follow up on isolated contamination incidents; check
 the effectiveness of U.S. regulations regarding chemical levels in foods; and guide other FDA food
 monitoring programs.
Summary of Environmental Data:

Media:  Drinking water, human food sources

Classes of compounds:  Inorganic compounds, semi-VOCs, pesticides, PCBs, radionuclides

Type of data available:  Individual data entries and summary statistics are available on specific
       agents

Estimation versus observational data: Estimates based on observational data

-------
Sample Design and Analysis:

       In the Total Diet Study, typically consumed foods are purchased at the retail level, prepared
for consumption, and analyzed for residue and dietary intake levels. The TDS was established in
1961 to determine dietary intake of radionuclides resulting from atmospheric testing of nuclear
weapons; analyses for selected nutrients and pesticides were  also performed.  Over  the years,
additional analytes have been added (currently, testing is  done for over 200 analytes, of which
approximately 51 are usually detected annually).  From 1961  to 1982,  the number and types of
foods, population groups, collection sites, and analytical methods varied.  Food was collected at one
location before 1982 (Washington DC) four times a year, and a "composite sample approach" was
used -- individually prepared food  group items were composited by weight.  Prior to 1982,  food
items and  diets  were based on the 1955 and  1965  U.S.  Department of Agriculture (USDA)
Household Food Consumption Surveys.

       The TDS was redesigned in 1982, based on updated analysis of individual  foods and new
dietary information from two surveys (the USDA 1977-1978 Nationwide Food Consumption Survey
(NFCS see entry in Appendix D) and the National Center for Health Statistics Second National
Health and Nutrition Examination Survey (NHANES) of 1976-1980) (see separate entry for this
database),  allowing for assessment of dietary intakes for a greater number of population (age-sex)
groups.  Since 1982, food collections (known as "market baskets") have been performed by  FDA
district office inspectors four times each year, once from  each  of four geographical regions of the
United States (East, West, South, and Central), representing the total diet of the U.S. population.
Each market basket  has consisted of 234 identical foods purchased in grocery stores in three  cities
within each geographical area; after food preparation according to specific instructions, the  three
subsamples of each food are combined to form a sample for analysis.  Individual analyses of 234
food items depicting eight population groups (ranging from infants to elderly adults) have  been
performed for over 200 analytes annually. Most of the analyses use multiresidue analytical methods.
Separate analyses are performed for radionuclides (for which monitoring was discontinued  from
1967-1972, and resumed in 1973).

       Total Diet Study analyses are performed for prepared, rather than raw, foods; therefore,
because food preparation may reduce levels of chemical residues, analytical procedures in the TDS
are modified from those used in other FDA regulatory programs to permit measurement at  levels
5 to 10 times lower than measurements used in those programs; generally, residues present at or
above 1 ppb  can be measured in the TDS.

       Results prior to and after 1982 are not directly comparable because of the  substantial
redesign of the Total Diet Study in'l982 (e.g., design of diets, analysis of individual foods versus
composites, expanded coverage of population (age-sex) groups, and use of different or additional
analytical methods). Beginning in the fall of 1991, the Total Diet Study has expanded its food
 collection and analysis to 265 food items, and will be expanding the number of age-sex population
 groups.

 Contact Person:  Steve Newburg-Rinn, U.S. EPA, Office of Toxic Substances, 401 M Street  SW
 	Washington, DC 20460, (202) 382-3757
 Objectives and Coverage:

        TRI contains data on annual estimated releases of over 300 toxic chemicals to air, water, and
 land by the manufacturing industry. (Releases to land include: landfills; land treatment/application
 farming; and surface impoundments, such as topographic depressions, man-made excavations, or diked
 areas.) Industrial facilities provide the information, which includes: the location of the facility where
 chemicals  are manufactured,  processed, or otherwise used; amounts of chemicals stored  on-site;
 estimated  quantities  of chemicals released; on-site source reduction and recycling1 practices;  and
 estimated amounts of chemicals transferred to treatment, recycling, or waste facilities. The Emergency
 Planning  and Community  Right-to-Know Act of 1986 and the Pollution Prevention  Act of 1990
 mandated that EPA collect this information and make it available to the public in a computerized
 database.

        Communities use TRI to obtain information about chemical releases in their area and for
 emergency response planning for chemical accidents. TRI data are also used by government agencies
 for regulatory purposes, such as permitting, inspection, and compliance reviews of facilities.  TRI is
 often used in conjunction with  other EPA databases to provide support for major environmental laws
 such as the Clean Air Act, the  Clean Water  Act,  the  Comprehensive Environmental Response'
 Compensation, and Liability Act (CERCLA), the Resource Conservation Recovery Act (RCRA)  the
 Toxic Substances Control Act  (TSCA),  and the Safe Drinking Water Act. In  addition, TRI data are
 used for research purposes by federal, state, and local governments and private  groups to study human
 health problems, particularly as a tool for risk screening to assess potential environmental and health
 risks.  More recently,  TRI has been used to encourage  and assist in implementation of pollution
 prevention (including source reduction) programs at industrial facilities.

 Summary of Environmental Data:

 Media:  Air (point and non-point source emissions), water, soil or sediment, bulk chemicals, ions
        (including fluoride), underground injection, off-site transfers  (including transfers to publicly
        owned treatment works, or POTWs)

 Classes  of compounds: Inorganic compounds, VOCs, semi-VOCs, pesticides, PCBs, asbestos, acids/acid
        aerosols, bases

Types of data available: Individual entries and summary statistics are available on specific agents

Estimation versus observational data: Most data are estimated; observational data are used if available;
       methods of estimation may change from year to year, causing apparent changes in values

                                           1-267

-------
Sample Design and Analysis:

       Title III of the Superfund Amendments and Reauthorization Act of 1986 requires facilities in
the manufacturing sector (Standard Industrial Classification codes 20-39) to report releases of over 300
specified chemicals in over 20 chemical categories to local and federal agencies.  Only those facilities
that have 10 or more full-time employees and either manufacture or process more than 25,000 Ibs. or
use more than 10,000 Ibs. of chemicals per year must comply.  These facilities must report annual
releases to their state and to EPA on July 1 following each calendar year of coverage.

        The TRI data for chemical releases to land are limited to releases within the boundary of a
facility    Releases  to  land include:  landfills;  land  treatment/application  farming;  and  surface
impoundments, such as topographic depressions, man-made excavations, or diked areas. Air releases
areidentified as either point source releases or as non-point (i.e., fugitive) releases,  such as  those
occurring from vents, ducts,  pipes, or any confined  air stream.   Surface water releases  include
discharges to rivers, lakes, streams, and other bodies of water. In addition, the database covers releases
to underground injection wells (where chemicals are injected into the groundwater) and offsite transfers
of chemicals to either publicly owned treatment  works (POTWs)  or any other disposal, treatment,
storage, or recycling facility.

        Release quantities are expressed as total annual amount, and the database does not indicate
whether peak releases or accidents occurred during the year. In addition, accuracy of data can vary
 ereatly  Estimates based on amount of chemical used during a year or on weight of drums can be fairly
 accurate. Where monitoring of waste streams has not been done, release estimates may be within 20
 percent of the actual amount released, although  infrequent nonrepresentative sampling may lead to
 much less accuracy. Estimates of fugitive air emissions and complex wastewaters for which monitoring
 data are not available may be off by one or even two orders of magnitude.  Overall, 1987 total annual
 releases appear to have been underestimated by 2 percent. For  non-zero release estimates, more than
 three-quarters were within a factor of 2 of EPA's best estimate.  About  15 percent were in error by an
 order of magnitude or more.  Finally, estimating exposure based on  release quantities  requires an
 analysis of chemical and site-specific characteristics; there is no simple conversion of release  quantity
 to concentration in the environment or dose received by individuals.

 Objectives and Coverage:

        TSCATS is an index of unpublished, nonconfidential studies covering  chemical testing
 results and adverse effects of chemicals on health and ecological systems. The studies are submitted
 by United States industry to the EPA under the Toxic Substances Control Act (TSCA).   The
 majority of these  studies include laboratory  studies conducted on chemicals.   There are few
 epidemiological studies and chemical spill studies included in the database, however, the emphasis
 is on laboratory studies.  Documents in the database include: TSCA chemical test results; health
 and safety  studies; notices of substantial risk of injury  to health or  the  environment;  and
 informational submissions that contain data on exposure, epidemiology, environmental fate, and
 monitoring.

       A TSCATS record includes the  chemical name,  Chemical Abstracts Service  Registry
 Number (CASRN), TSCA  section,  title, public  file document number,  microfiche  number,
 submitting organization, performing organization, study purpose, chemical effect,  organism tested,
 route of administration, and keywords  and abstracts for a select number of studies.  Submitted
 documents are available on microfiche within the TSCATS system.

       TSCATS contains information that is pertinent to the risk assessment and hazard evaluation
 processes.  The information can be used in conjunction with published material and is a valuable
 source in the absence of published data.  The data are used by federal and state agencies,
 researchers, toxicologists, risk assessors, and trade and professional associations.
Summary of Environmental Data:

Media:  Bulk chemicals

Classes of compounds: Inorganic compounds, VOCs, semi-VOCs, pesticides, PCBs, dioxins/furans,
       radionuclides, asbestos, acids, bases, all other substances covered under TSCA

Objectives and Coverage:

       The Total Exposure Assessment Methodology (TEAM) was designed by the EPA to develop
and demonstrate methods to measure human exposure to toxic substances in air and drinking water.
(See also the Nonoccupational Pesticide Exposure Study (NOPES), the Carbon Monoxide TEAM
Study (CO TEAM), and the Particle TEAM Study (PTEAM) in this Inventory.) The goals of VOC
TEAM were to develop methods to measure individual total exposure (from air, food, and water)
and the resulting body burden of toxic and carcinogenic chemicals, and to apply these methods
within a probability-based sampling framework to estimate exposures and body burdens of urban
populations in several U.S. cities.  To achieve these goals, air sampling was conducted to measure
personal exposure to airborne toxic chemicals and a specially-designed spirometer was developed
and used to measure the same chemicals in exhaled breath. The survey design consisted of a three-
stage stratified probability selection approach to ensure inclusion of potentially highly exposed
groups.  Related objectives  of the VOC .TEAM studies were  to: determine the relationships
between personal, indoor, outdoor, and blood, urine, and exhaled breath concentrations; determine
the variability of VOC concentrations within  a home; and determine seasonal and multi-year
variability.  The Study was conducted in three phases.

       A field test of the methodology (Phase I) was carried out between July and December 1980
in Bayonne, and Elizabeth, New Jersey and Research Triangle Park, NC.  The objective of Phase
II, carried out between September 1981 and February 1983, was to estimate the distribution of
exposures to target substances for a target population in an industrial/chemical manufacturing area
(Bayonne, and Elizabeth, New Jersey) and to compare these estimated exposures to those estimated
for populations in nonchemical manufacturing areas (Greensboro, NC and Devils Lake, ND).  In
Phase IE, carried out between February and June 1984, the methodology refined during Phase II
was applied to target populations in California.  After completion of these three phases, a separate
VOC TEAM study was carried out in Baltimore, MD during 1987 because Baltimore lacks the
petroleum and chemical manufacturing plants present in most of the previous TEAM study sites
and may therefore be more representative of many U.S. cities.  Focused studies were also
conducted in New Jersey and Los Angeles during 1987 to further explore the sources and factors
contributing to personal VOC exposures identified in the earlier TEAM studies.

Summary of Environmental Data

Media:  Air, water, human samples (exhaled breath)

Classes of compounds: VOCs

"types of data available: Individual data entries and summary statistics on specific agents

Estimation versus observational data:  All observational data

Sample Design and Analysis:

      Major studies were conducted in two areas:  Elizabeth, and Bayonne, New Jersey; and Los
Angeles, Antioch, and Pittsburgh, CA.  In addition, two smaller comparison studies were conducted
in Greensboro, NC and Devils Lake, ND.  In New Jersey, an initial probability sample of 11,400
residents (5,550 households) located in 108 areas  in Elizabeth and Bayonne were polled to collect
data on  age, sex, occupation,  and smoking status.   A stratified  probability sample of these
individuals yielded 355 participants. The probability-based survey design provided a basis for robust
inferences to the approximately 128,000  members  of the target population, which included
individuals who were over 6 years of age and were residents of the target cities when the study was
conducted in the fall of 1981.  A return visit was made to 157  of the  original participants in the
summer of 1982, and a final visit was made to 49 of these 157 persons during January and February
of 1983. The individuals contacted on each return visit were a probability sample of the participants
from the  previous visit.   All participants also completed questionnaires about their age,  sex,
occupation, and activities during the sampling period.  An extensive quality assurance program was
implemented for all sampling and analysis activities.

      Two comparison studies were  conducted.  A  small comparison study was undertaken in
Greensboro, NC in May 1982.  Greensboro was selected because its population is similar in size to
the Bayonne-Elizabeth area and it has similar small industries, but no chemical manufacturing or
petroleum refining operations.  The target sample size was  set at 25 for  a 3-stage sample survey
designed to represent 131,000 Greensboro residents. The location of the second comparison study,
Devils Lake, ND, was selected to investigate whether  the population of a  small, rural, agricultural
town far from any industry would exhibit personal exposures different from those of the northern
New Jersey  population. The target sample size was set at 25 subjects  to represent approximately
7,000 residents.

       Between February  and March of 1984,  117 residents selected  from 1,063 households
representing 360,000 residents in the South Bay section of Los  Angeles participated in the study.
Between May and June of 1984, a second study  included 52 of these participants.  During June
1984, residents of Antioch, and Pittsburgh, CA were selected for participation from 502 households
representing a population of 91,000. The overall response rates in the TEAM studies ranged from
44 percent in New Jersey  to 76 percent in North Carolina.  Los Angeles and Antioch/Pittsburgh
overall response rates were about 57 percent while the overall response rate in North Dakota was
64 percent.

       Personal and outdoor air samples were collected in glass cartridges containing solid granular
sorbent Tenax-GC using DuPont sampling pumps  for 12 hours at  approximately 30 mL/minute

                                           1-276

 (target volume of 20L).  Breath  samples were collected using a specially-designed spirometer
 mounted in a van. The subjects provided breath samples at the end of the 24-hour sampling period.
 Water samples were collected from the tap at each participant's home after a 20-second flushing
 period.   Samples were collected in 2-ounce glass jars containing sodium thiosulfate to quench
 residual chlorine reactions.

        Air and breath samples were analyzed by capillary gas chromatography mass spectrometry
 (GC-MS) techniques followed by  a combination of manual and automated analyses of spectra.
 Water samples were analyzed by a purge and trap GC utilizing a Hall electroconductivity detector
 for halogenated compounds and a flame ionization detector for  aromatics.

       A total of nearly  5,000 air, breath, and drinking water samples were collected for 400
 respondents  (600 person-days)  in the New Jersey, North Carolina, and North Dakota sites. This
 represented  about 95 percent of all samples originally  scheduled.  During the California phase,
 about 1,800  air, breath, and drinking water samples were collected from  188 respondents (240
 person-days).  This represented about 98 percent of all  samples  originally scheduled.

       In 1985, Congress appropriated resources for further studies of exposure to VOCs.  In
 response, three studies were carried out in 1987 in Los Angeles, CA; Baltimore, MD; and New
 Jersey. The  major goal of the February 1987 Los Angeles VOC TEAM Study was to determine
 the personal, indoor, and outdoor air concentrations of 25  VOCs for  a subset of Los Angeles
 residents.  The major goals  of the later study in July  1987 (cosponsored by the EPA and the
 California Air  Resources Board) were to measure VOC concentrations in personal/indoor, and
 outdoor air in the exhaled breath of persons living in households that had previously been measured
 in 1984; to determine room-to-room variability within homes; to determine source emission rates
 by  measuring air exchange rates in each home; and to extend the coverage of chemicals sampled
 and analyzed by employing additional sampling and analysis methods.  The samples were collected
 primarily  using Tenax cartridges.

       The primary goal of the Baltimore study was to determine the frequency distribution of the
 VOC exposures of a subgroup of Baltimore residents. About 150 residents drawn from two areas
 representing different socioeconomic groups participated in the study; As in the Los Angeles study,
 personal,  indoor  and outdoor air  concentrations were  measured over two consecutive 12-hour
 periods, and breath samples were collected at the beginning and  end of each period. Most of the
 indoor and outdoor air samples were collected using  evacuated cylinders, rather than Tenax
 cartridges. Air exchange measurements were again taken for all homes.

       In 1987, the TEAM study in New Jersey focused on several sources of exposure in 11 homes
 for the purpose of testing hypotheses formed as a result of earlier TEAM studies.  Hypotheses
 regarding   major sources  of  exposure to  several chemicals  included:    1) exposures  to
 tetrachloroethylene are mainly due  to storing dry-cleaned clothes  in the home or wearing them; 2)
 exposures to  aromatic compounds  may be partially due to storing cars, lawn mowers, gasoline,
 kerosene,  etc. in attached garages  or other areas in the home;  and 3) hardware stores may be
important sources of exposure to many toxic organic chemicals. Personal, indoor, and outdoor air
samples, and  breath samples were collected for each participant over a 3-day or 5-day monitoring
period.  Air exchange rates were also measured to allow the calculation of source emission rates.

 other  sources of groundwater,  and includes  site location and  identification,  geohydrologic
 characteristics, well construction  history,  and  one-time  field measurements  (such as water
 temperature).  The Daily  Values File includes parameters measured or  observed on a daily or a
 continuous basis, such as streamflow, river stages, reservoir contents, water temperatures, specific
 conductance, sediment concentrations and discharges, and groundwater levels. The Unit Values File
 contains information on water parameters measured on a schedule more frequent than daily such
 as rainfall, stream discharge, and temperature data. The Peak Flow File contains peak observations
 for annual maximum streamflow and gage height values at surface water  sites. The Water Use File
 contains summary data on water use throughout the United States.  The Station Header File is an
 index of sites from three other WATSTORE files (the Daily Values, Peak Flow, and Water Quality
 files), and includes information such as identification, location, and physical  description of sites.


       The hydrologic data contained in WATSTORE are used by government agencies and private
 organizations to determine the adequacy of water supplies; design dams, bridges, and flood control
 projects; allocate irrigation waters; locate sources of pollution; plan for energy  development; and
 predict the potential effect of radioactive waste disposal on water supplies. In addition to its data
 processing, storage, and retrieval capabilities, WATSTORE can provide a  variety of products,
 ranging from simple data tables to complex statistical analyses.

       The  USGS  is presently in the  process  of designing  a new system which will replace
WATSTORE.  This new system will be  called the National Water Information System II and will
include a broader range of environmental data than the current WATSTORE database (e.g., when
and where samples were collected). Although the design of the program will  change, all of the
information from the current WATSTORE database will be transferred to the new system and will
be available  to users.  The new system will be phased in during 1993 and 1994.

 Summary of Environmental Data:

 Media:  Surface water; ground water; leachate; municipal and private water; precipitation; soil and
        sediment

 Classes  of compounds:  Inorganic compounds; VOCs; trihalomethanes; semi-VOCs; pesticides;
        PCBs;  dioxins/furans; radionuclides;  asbestos; microorganisms; physical and  chemical
        indicators of water quality; ions (including fluoride and chloride)

 Types of data available: Individual data entries on specific agents

 Sample Design and Analysis:

        The  USGS collects data at stream gaging stations, lakes, reservoirs, surface water quality
 stations, sediment  stations,  water  level observation wells,  and ground water quality wells.
 Monitoring sites are selected based on the specific purpose of the individual project (e.g., long term
 trend analysis;  determination of the general characteristics  of  an  area;  a specific, identified
 problem). Each year many water data collection sites are added and others are discontinued.

 As of 1981, the Station Header File included information on nearly 263,000 sites; the Groundwater
 Site Inventory File  contained data for nearly 700,000 sties; the Water Quality File had  results of
 more than 1.8 million analyses for 185 different constituents; and  the Daily Values file contained
' more than 200 million daily values.

        Digital recorders are used at many field locations to record values for parameters such as
 river stages, conductivity,  water temperature, turbidity, wind direction, fluorides, and chlorides.
 Data are recorded and transmitted to the central computer facilities of the USGS at its National
 Center. Samples requiring laboratory analysis are analyzed at one of two laboratories of the Water
 Resources Division and results are transmitted to the central computer facilities.

  Objectives and Coverage:

        The Western Lake Survey, Phase I, was conducted in 1985 as part of the National Surface
  Water Survey, which also included the Eastern Lake Survey and the National Stream Survey (see
  entries on these databases elsewhere in this Inventory). The purpose of the National Surface Water
  Survey was to assess through monitoring the effects of acidic deposition on surface waters. The
  primary  objectives of the  WLS were to determine in potentially sensitive areas  of the western
  United States 1)  the percentage and location of lakes  that were  acidic; 2) the percentage and
  location of lakes that had low acid neutralizing capacity (ANC); and 3) the chemical characteristics
  of lakes,  providing a database for selecting lakes for future studies.

Sample Design and Analysis:

       A statistical procedure was applied in selecting a subset of lakes in the.western United
States as a probability sample to estimate the physical and chemical characteristics  of a target
population of lakes from the results of the chosen sample with a known degree of confidence.  A
total of 719  lakes were sampled, representing  an estimated 10,393  lakes in the  target  lake
population. In addition, 32 special interest lakes were sampled. A majority of the lakes sampled
were expected to exhibit low alkalinity.  A single sample was collected from each lake in the fall;
thus, results are applicable to the fall season only; representation of other periods during the year
(e.g., levels in the spring of 1985) in western lakes is unknown.

Objectives and Coverage:

       The Wisconsin Fisheries Database (FISH.WIS), a merger of a biological and a chemical
database, covers over 400 lakes in northern Wisconsin.  FISH.WIS was originally created to assess
acid rain impacts on lake biota (e.g., fish health in relation to water quality) by adding fisheries
records to chemical data about the lakes studied.  Information on the presence of metals in lakes
was  also included.  Data in FISH.WIS include lake chemistry and composition, drainage (e.g.,
agricultural or natural areas), inlet and outlet information,  water source, flow information, a
pollution index (indicating absence or presence of pollution), and information on the presence of
fish  species with codes of relative abundance.  FISH.WIS is designed to assess rural areas having
minimal human disturbance. Completed in 1984, this database is currently not funded. It has not
been used to examine the effects of water quality on fish or to study ecological relationships.
 Summary of Environmental Data:

 Media: Surface water

 Classes of compounds:   Inorganic compounds, ions (including nitrate,  sulfate, phosphorous,
       ammonia, magnesium, calcium, iron), physical and chemical indicators of water quality

-------
 Sample Design and Analysis:

        For chemical analysis, lakes representative of the aquatic (recreational) resources in the
 region were sampled to assess factors that might make the lakes susceptible to acidification.  The
 study area encompassed lakes within the Upper Wisconsin River Basin, bounded by the coordinates
 46°07'N, 89°09'W to the north and 45°11'N, 89°41'W to the south. Approximately 90% of the land
 was forested, with a  relatively low population density (9.3 persons/km2).  Lake  selection was
 intentionally biased to include most lakes in the study area with surface area greater than 100
 hectares (ranging to as small as 3.9 hectares) for which no recent water quality data were available.
 Direct sampling was done for physical and chemical characteristics. Both in-lake and watershed
 measures were obtained.  In addition, a cluster analysis was performed using alkalinity, color, and
 chlorophyll a data, which resulted in three clusters of lake types: lakes dominated by surface runoff;
 lakes dominated by groundwater; and those dominated by precipitation. Further analysis of factors
 that may contribute to lake susceptibility to acid precipitation was conducted through discrimination
 analysis of 18 watershed characteristics  across the three lake clusters. Records obtained from the
 Wisconsin Fisheries Department indicating the presence of fish species were then added to the
 chemical database.  The measurements showed that the potentially sensitive low alkalinity lakes in
 northcentral Wisconsin lack surface inlets or outlets, and that their chemistry is associated with
 precipitation chemistry.

 Description
    I
        The Acid Deposition Data Network was  established in 1978 to provide reliable data to
 support assessments and policy analysis for the National Acid Precipitation Assessment Program
 (NAPAP) and to facilitate timely exchange of accurate, usable data among NAPAP and other data
 sources. This database provides national geographic coverage from 1970 through 1988. ADDNET
 lost funding in 1988, but the information is archived. The.component databases were divided into
 various subject areas:  agriculture,  geographic base data (e.g., U.S. Census county codes), climate,
 vegetation,  forestry,  air  quality,  land use/land  cover, population, water quality, and terrain.
 Pollutant source information is available, and dispersion information is available for air but not for
 water.  When the program  was fully funded, researchers from state and federal agencies  could
 request specific reports and data link-ups.


                                     DATA SOURCES

       ADDNET contains 55 data sets that have been certified to ensure consistency across all
. areas of assessment.  The objective was to link approximately 50 independent state and federal
 agency  databases (over 30 additional data sets were being edited for addition to ADDNET when
 the program lost  funding; these additional data sets were never included). Each component data
 set was responsible for designing and implementing its own sampling strategy and collection.  Ten
 of the 55 integrated databases are related to atmospheric and water chemistry. These databases
 contain measurements in each of the media for criteria pollutants, VOCs, particulates, and physical
                                           II-l

-------
ADDNET, QA/QC spot-checks were conducted to verify information, but, in general,  QA/QC
procedures were prepared by each of the individual  data sources.  ADDNET spot-checked
individual values and traced the values back to the data  entry of the component database.
                                 DATA PRESENTATION

       The ADDNET program put the individual databases into a common format, converted all
units to metric units,  and established consistent codes for missing fields and values.  Individual
entries, summary statistics, and cross-referenced data are available. Observational data provide the
basis for county-level estimates.   ADDNET data can be identified by latitude/longitude of the
county centroid, point source and monitor site, and physical description of the point source, monitor
site, county, and state. Samples were collected monthly or annually (when aggregated).

Description

       ACID was established to analyze the effect of acid deposition on surface waters of the
United  States by examining historical trends at regional  and national  scales.  ACID is  a
comprehensive database that combines data from existing computerized databases (e.g., Storage and
Retrieval of Water Quality Data (STORET)) with other data sets from a variety of sources (e.g.,
state agencies). Approximately 75 percent of the sampling stations come from STORET. ACID
currently contains data for  the 48 contiguous United States from 48,692 water quality sampling
stations and 819,002 sampling dates.  Data in ACID include hydrology, acidity, water chemistry,
limited lake and stream morphometry, and station information divided into 10 regions:  Northeast,

Description

       AIRS is a national repository for data on airborne pollution in the United States.  AIRS
includes compliance data for airborne criteria  pollutants—lead, CO, SO2, NO^  ozone, reactive
volatile organic compounds (VOCs), and particulate matter  (either total suspended particulates
(TSP) or particulate matter less than 10 microns in size (PM10))—for which National Ambient Air
Quality Standards (NAAQS) have been set. In addition, AIRS contains information on air quality,
point source emissions, and area/mobile source  data on a wide variety of other pollutants.  AIRS
can be used to generate reports on air quality and emissions for various pollutants for specific time
periods and geographic areas.  Maps showing the monitoring sites can also be generated.

       AIRS was established in 1987 and replaced the Storage and Retrieval of Aerometric Data
(SAROAD), National Emissions Data System (NEDS), Compliance Data System (CDS), National
Air Monitoring Stations (NAMS) Management Information Systems, Comprehensive Data Handling
System (CDHS), Air Quality Data Handling System (AQDHS-II), and the Emission Inventory
System/Point Source and Area Source (EIS/PS  and EIS/AS).  AIRS also contains summary data,
but not raw data, from the National Park Service Environmental Database Management System
(NPSEDMS) and from the Precision and Accuracy Reporting System (PARS), which includes data
on instrumentation, measurements, and calibration.  AIRS contains some,  but not extensive,
meteorological data from some air quality monitoring sites.
                                         II-4

-------
        AIRS does not include information on toxic waste sites (CERCLIS), or information from
 the Toxic Release Inventory (TRI) or the National  Air Toxics Information  Clearinghouse
 (NATICH),  among other data systems.

        EPA uses AIRS data for regulatory, monitoring, and research purposes, such as assessing
 the nation's air quality, setting national ambient air quality regulations, identifying localities where
 improvements in air quality are needed, estimating national air emissions and trends, and preparing
 reports  mandated by the Clean  Air Act.  States use  AIRS information to  develop  State
 Implementation Plans. In addition, many states store a wide variety of data on other pollutants and
 variables in AIRS (e.g., through the State and Local Air Monitoring Stations (SLAMS) system).
 AIRS data have been used for exposure, assessment and in  the development of EPA Criteria
 Pollutant Documents.
                                     DATA SOURCES

        As of 1989, AIRS contained approximately 500 million air pollution measurements, primarily
 in heavily populated, urban areas. AIRS consists of four subsystems: air quality subsystem, facility
 subsystem, area/mobile source subsystem, andgeo-common subsystem. The geo-common subsystem
 contains reference information on codes  and code  descriptions  to  identify places,  pollutants,
 processes,  geo-political entities, numerical values, etc.  The other three  systems  contain data
 contributed by states under several federal regulations, as well as additional data that states may
 choose to store in this system.

 Air Quality Subsystem

        The Air Quality Subsystem (see database description in Part I of this Inventory)  contains
 measurements of ambient concentrations of air pollutants and associated meteorological data. The
 data are reported by states under U.S. EPA regulations on a quarterly basis.

Air Facility Subsystem

       The Air Facility Subsystem (see the description of this database in Part I of this Inventory)
contains aerometric emissions and regulatory compliance data on air pollution point sources tracked
by the U.S. EPA, state, and local air regulatory agencies. Data from states are reported on a yearly
basis.-                                                                               J    J

Area/Mobile Source Subsystem

       The Area and Mobile Source  Subsystem is scheduled for production in mid-1992.  This
subsystem will contain emission inventories from small stationary  and mobile sources, forest fires,
fugitive transport,  and natural sources of air pollution.  Data  will be stored for all counties
nationwide beginning with data from 1990; for nonattainment areas, data will be available on the
county,  city, or zone level.

-------
                                 DATA PRESENTATION

       AIRS uses the Adaptable Database (ADABAS) database management system. NATURAL
and VS-COBOL are used to update and access data from AIRS.

       AIRS provides the user with a variety  of standardized  report formats.   These include
quarterly or yearly maximum values or averages for individual monitors by pollutant; the 10 highest
values  recorded at a monitor presented by quarter or year with time/date notation; all raw data
values  for a specific time period; box plots for individual monitors by pollutants; and monitor and
monitor site characteristics.  Data can be selected for analysis based on measurement frequency or
other air quality parameters, such as maximum  daily temperature.  Data can be averaged over
monitors (e.g., over geographic areas), and over time periods. The Pollutant Standards Index (PSI)
can be presented for urban area trends.

       In addition, the user can use NATURAL to write new formats for reports.  Alternatively,
work files can be created from AIRS that can then be accessed by other software packages (e.g.,
FORTRAN, COBOL, BMDP, IMSL, SAS, or DISPLAA), to generate new reports.
                                  DATA AVAILABILITY

Level of Data Aggregation: Individual data entries and summary statistics are available on specific
       agents; summary  statistics are computed for calendar quarter and year for  individual

                          COAL TECHNOLOGY DATA SYSTEM
Acronym: None
Sponsoring Agency:  U.S. Department of Energy (DOE), Pittsburgh Energy Technology Center
       (PETC)
Contact Person: Richard DeSantis, U.S. DOE, PETC, Box 10940, Pittsburgh, PA 15236, (412) 892-
       4761
Description

       PETC, which specializes in coal research, collects data from approximately 100 sources and
includes it in the Coal Technology Data System, a data handling system on energy information from
U.S. power plants. The Coal Technology Data System includes information on emissions sources;
utilization of coal, with limited information on oil, gas, and nuclear energy; trace element toxicity;
raw coal characteristics; coal shipment data; boiler characteristics  (size, manufacturer, firing type,
etc.); washability (potential for cleaning coals); and the relationship between certain emissions (e.g.,
oxides of nitrogen) and boiler characteristics. Data are organized into approximately 100 databases,
four of which are available in the personal computer (PC) version; these four include: Reserves,
Shipment, USGS, and Washability.  Other databases in this system include:  Advanced Combustion
Technology, Alternative Fuels, Clean Coal Technology, Coal Preparation, Flue Gas Clean-up,
Liquefaction, and a bibliographic database, which catalogues nearly 1000,000 DOE/PETC-sponsored
research reports and items of historical significance in the field of coal utilization technology. Users
of the system  can calculate air emissions  (oxides of nitrogen  and  sulfur,  carbon  monoxide,
particulates, and trace elements) from given data on feed and burn stock and clean-up equipment,
using models provided in the system.  The Coal Technology Data System is used for a variety of
purposes specific to individual needs, e.g., to determine engineering and administrative controls for
the purpose of reducing pollution and energy costs.


                                     DATA SOURCES

       The Pittsburgh Energy Technology Center obtains, processes, and updates existing data from
other sources  for the Coal Technology Data System.  Coal shipment data are obtained from the
Federal Energy Regulatory Commission (FERC) Form 423: Monthly  Report of Cost and Quality, of
Fuels for Electric Plants (data on monthly deliveries of fuels to plants and on fuel quality); other
information on coal is obtained from the U.S. Geological Survey (USGS). Boiler characteristics
are obtained from the Energy Information Agency (EIA) Form 767: Steam-Electric Plant Operation
and Design Report (fuel consumption  data for individual boilers) and from commercial sources.
Data used to calculate emissions are also obtained from EIA Form 767. The relationship between
oxides of nitrogen and boiler characteristics are obtained from research literature.

       The Reserves Database includes the results of fifteen parameters measured in 1,431 samples
of U.S. coal. The measured parameters include:  percentages of moisture, dry volatile matter, fixed
                                           II-8

-------
 dry carbon, dry ash, dry sulfur, dry hydrogen, dry carbon, dry nitrogen and dry oxygen; dry heating
 value; ash-softening temperature;  free-swelling index; hardgrove grindability index; underground
 tons; and strip tons.  These data were primarily obtained from state agencies which participated in
 a 1974 survey of U.S. coal mines.

       The Shipment Database includes  five parameters  in  yearly averages  describing coal
 shipments from approximately 2,000 mines to 405 power plants. Parameters include:  quantity
 shipped from mines or received by power plants; heating value (BTU/lb); percentages of sulfur and
 ash; and cost/million BTU. Megawatts are included for all types of power plants.

       The USGS Database includes the results of 4,043 coal  samples covering 92 parameters,
 including major, minor, and trace element analyses.  These samples were collected by USGS from
 approximately 100  points in the  United States, and results were  forwarded to PETC.   This
 information is occasionally updated.  Also included is geological information on U.S. coal seams,
 including items such as coal seam thickness and depth.

       The Washability Database, which describes the potential for cleaning coals, is determined
 by PETC.  This  database includes 312 parameters describing 975 samples  of U.S. coals.


                                 DATA PRESENTATION

       PETC staff can manipulate each of these databases to present pertinent information in a
 variety of formats, e.g., a U.S. map of fixed carbon in coal or a sulfur dioxide emissions profile of
 pre-1980 electric utility boilers.
                                  DATA AVAILABILITY

Level of Data Aggregation:  Individual data entries and summary statistics (yearly averages) are
       available  for  data in the  four  PC  version  databases  (Reserves, Shipment,  USGS,
       Washability); individual data entries are available for all other databases

       20585, (903) 353-5926
Description

       CEDR is being developed as one of the components of the Department of Energy's (DOE)
Epidemiology and Health Surveillance Program.  The objective of CEDR is to collect and organize
data arising from epidemiologic studies of DOE workers and other populations, such as those living
in the vicinity of DOE facilities. These  studies will include DOE-sponsored research  as well as
other data made  available to DOE for inclusion in the data system.  The purpose of this data
system is to encourage research  that evaluates health effects of exposure to low levels of radiation
in these populations.  The data will be organized so that a wide range of users will have access to
the data for further analyses or meta-analyses.  (During the development of,the system, however,
access to the data is limited.)  Broad scientific use of these data and the associated diversity of
analyses  and conclusions should provide support to improve methods of data collection and
analyses.
                                    DATA SOURCES

       CEDR is compiling data from existing studies, and is not designing these studies. The data
that will be included are largely DOE-supported studies to assess  the  health  and mortality
experience of DOE contractor employees and to evaluate the health effects of exposure to low
levels of radiation in these employees.  Other types of data being considered for inclusion are
ecologic and community studies.

       Data elements included in the system include unique ID numbers, demographic and socio-
economic information, employment and work history, exposure, and health data. Exposure data
are based on both observational measurements, (e.g., personal monitors), and estimated exposures.
The extent of information and method of exposure determination vary between studies.

       The initial studies  included over approximately 110,000 workers at various  DOE sites,
including Hanford, Oak Ridge, and Rocky Flats.  The extent of studies included in  CEDR may
change as the  system evolves.  Other types of data, such as employment in non-energy-related
occupations in which radiation exposure is possible, have also been discussed.

                                 DATA PRESENTATION

       The CEDR data management system is being developed at Lawrence Berkeley Laboratories.
The capabilities include storage, documentation, retrieval of descriptive information, and specially
developed browsing capabilities.  Using a specially developed X-windows-based browsing/query
system, the browsing capabilities allow the user to examine and explore the contents of all databases
in the system, mark desired data for selection,  and extract that data into a new data set.

        Storage and Retrieval of Water Quality File (STORET)
        Permit Compliance System (PCS)


 Description

        EDM ties together national on-line databases that contain spatial and attribute information
 on industrial and municipal dischargers, drinking water  supplies, stream flow,  water quality
 monitoring stations, discharge permit compliance reports, and hydrologic maps. EDM provides easy
 access to these data; automated environmental analyses, reports, and data; graphics; images; text;
 and documents that can be used by numerous output devices, software packages, and computers.
 EDM can be  used  to generate  reports on  multiple  individual  pollutant and  water quality
 measurements at specific locations. With maps, the user can look at the rivers in  any state, can
 zoom in on a small pond, and can overlay and identify particular features. Maps showing locations
 of discharge permitted facilities, surface water supplies (including utilities, intakes, and sources),
 and population centers can also be generated.  Maps  also display roads, rivers,  and lakes.  The
 detail of the map is flexible.

       EPA uses EDM for regulatory, monitoring, and research purposes such as assessment of the
 nation's water quality, environmental planning, developing and promoting environmental laws, and
 environmental enforcement.  Reports from EDM can be used for education and public awareness.


                                    DATA SOURCES

       The mapping component of EDM works with an electronic version of the 54,000  base maps
of the U.S. Geological Survey, also known as the 7.5-minute quadrangle maps. These maps portray
features at the 1:100,000 scale. The hydrologic data from these maps are stored separately as the
River Reach file. This file includes over 100 million records containing the latitude and longitude
coordinates of streams,  lakes, reservoirs, estuaries,  and shorelines in  the United  States.   Also
included in  the  mapping  component  of EDM are the latitude/longitude,  stream reach cross
references, and population of cities in the United States.
                                          11-13

-------
       Information on water comes from two sources: the Storage and Retrieval of Water Quality
File (STORET) and the Permit Compliance System (PCS). Detailed information about these data
systems can be found in Part I of this Inventory.

       STORET contains geographic and other descriptive data about the sites where water quality
data have been collected.  Data include physical characteristics and chemical constituents of the
water,  fish tissue, or sediment sampled.  This file contains over 200 million water sampling
observations.   (Information about the flow in the stream is stored in the Stream Gage File.)

       The  PCS  database   is  the  national  inventory   for   EPA  permit  issuance  and
compliance/enforcement data. The database consists of more than 5 million records on over 75,000
active water discharge permits. (Information about the facilities is stored in the Industrial Facilities
Discharge File.   This file does not contain measurements  but does contain  information as to
indirect dischargers to sewage treatment plants,  standard industrial classification codes, receiving
stream, and categorization of industrial process.)
                                 DATA PRESENTATION

       EDM provides the user with a variety of report, graph, and map formats. EDM can access
data for any geographic region in the continental United States.  Data can be accessed either
through EPA discharge permit numbers, latitude/longitude, water body, city, county or state name,
river reach or water quality station,  or pointing to states on a U.S.  map  and then  successively
narrowing down the regions.  Report formats include data inventories for selected sampling sites;
lists of facilities, cities, and water quality stations within  a designated area; data summaries for
specific parameters and time periods at selected sampling sites; and water supplies downstream of
designated facilities (size of population served is also included). Graph formats include line graphs
and histogram presentations of specific measurements or summary measurements of one or multiple
parameters.  Maps can be generated at a variety of levels  of detail and the overlay information is
user specified.  Further, routing of the streams can be displayed.

       EDM is available  through the EPA National Computer Center  and communications
network. EDM uses IBM's Graphics and Data Management System and UNIRAS graphics. The
user interface is interactive with the menu specifying the functions that can be selected at each step.
Lists are also available for many of the more detailed and numerous data. For instance, if the user
is unfamiliar with the 7.5-minute quadrangle maps in the area of interest,  a list of maps for the area
can be displayed.

pollutants, assess the fate of chemicals in theoretical and in geographically specific environments,
model the resulting chemical concentrations, determine the number of people potentially exposed,
and  estimate the resultant human exposure and risk.  GEMS has modeling capabilities for the
atmosphere, surface water, unsaturated land (soil), saturated zones (ground water), and multimedia.
GEMS contains a variety of models for each media.

       GEMS  contains a range of data sets that help the user  determine  the  environmental
characteristics of the specific area. These include data on the population (including demographic
characteristics as well as  location of cities),  atmospheric, water,  and soil characteristics (e.g.,
climatic, soil  property, and stream flow data), ecosyste'm  characteristics,  and  water supply
information. GEMS also includes data sets that identify and characterize potential chemical release
sites  as well as monitoring stations.   These  data sets include information on  publicly owned
wastewater treatment works  (POTWs), and industrial  facilities, identified through  the Permit
Compliance System  (PCS), the National Emissions Data  System (NEDS), and the National
Pollutant Discharge Elimination System (NPDES). In general, the user provides information on
the pollutant discharged such as amount, concentration, or source. However, data are also directly
accessible from the Toxic Release Inventory  (TRI). Data sets are also available that provide
information on chemicals and their properties.

-------
       GEMS was originally designed in 1981 for EPA scientists and modelers who needed a tool
to provide comprehensive policy planning support to EPA administrators.  The system facilitates
both exposure and risk assessments.  GEMS is now available to any requester through the EPA
VAX cluster or by purchase of the PC version.
                                     DATA SOURCES

       GEMS has a flexible geodata handling system. The user may specify the location using the
zip code, universal transverse mercator coordinates, latitude and longitude, or Federal Information
Processing Standard (FTPS) codes for a state  or county.  Locations of water systems can be
identified through hydrologic unit codes or river reach numbers.  Then, using a cross-referencing
program, the system can access any of the data sets through the geographic codes of the data set.

       Information on potential chemical release sites comes from several sources.  Sites include
POTWs, industrial sites, and underground storage tanks.

       POTWs are identified in the NEEDS86  file, the  1986 Needs Survey Report to Congress,
Assessment of Needed Publicly Owned Wastewater Treatment Facilities in the United States.  This
provides information on the location, unit treatment process, influent and effluent descriptors, flow
rates, and population served.  The file does not contain measurements of pollutants  in influent or
effluent.

       Industrial facilities are  listed in the  Industrial Facilities  Discharge File.  This file was
assembled from three  databases that contain  information on direct and indirect dischargers (from
the Permit Compliance System  (PCS)). The PCS database is the national inventory for EPA permit
issuance and compliance/enforcement  data.   GEMS  includes information on over 28,000 permits
for dischargers.  Detailed information on PCS can be found in the first section of this Inventory.
GEMS also includes information on over 12,000 industrial facilities  that discharge waste through
other facilities, usually POTWs. The Industrial Facilities Discharge File of GEMS does not include
measurements, but it does contain Standard Industrial Classification (SIC) codes, categorization of
the industrial process, receiving water  systems, and other pipe-related data.

       The Leaking Underground Storage Tank (LUST)  survey is used to provide information on
underground tanks. The file includes site location, climate, soil, ground water,  and geologic data.
No measurements are  available on the amount and type of pollutant that might be leaking from the
tanks.

       Information on estimated  industrial  facilities discharges comes from  the Toxic Release
Inventory (TRI).  TRI contains data on annual estimated releases of over 300 toxic chemicals to
air, water, and land by  manufacturing industries.  Information includes amounts of chemicals stored
on site, estimated quantities of chemicals released, onsite  source reduction and recycling practices,
and estimated amounts of chemicals transferred to treatment, recycling, or waste  facilities. Detailed
information about this data system can be found in the first section of this Inventory.
                                          11-17

-------
       The amount of information available on potential polluters and environmental characteristics
varies with geographic location. For instance, although TRI is available for -all 3,078 counties in
the United States, the soils data set is available for only 2,571 counties, the climatic data comes
from 3,225 stations throughout the United States, and ground-water data come from 14 cities in the
contiguous United States.
                                  DATA PRESENTATION

       GEMS provides the user with a variety of graphical displays. • Statistical analyses on the
numeric variables  are generated using library routines from the International Mathematical  and
Statistical Library (IMSL) and the Statistical Analysis System (SAS). The results can be presented
through line graphs, histograms, scattergrams, 3-dimensional isopleth graphs, and circular graphic
representation (Rose procedure).

       GEMS also has mapping capabilities that allow the user to specify the area to be mapped
either by listing the block group (or census enumeration district),  county or state, or hydrologic
units, or by specifying the radium of a circle centered on a location identified by the user.  Maps
can be produced that display the location of important sites such as industrial sites or monitoring
sites, that use dot-density to display geographic distribution of data,  or that use shading to indicate
various levels of estimated values.

       GEMS is available through the EPA National Computer Center and the communications
network. A PC version of GEMS (PCGEMS) is also available with air, surface water, and ground-
water models and associated environmental and 1980 population data for most of the United States.
The user interface is interactive with a question/response  format.  The User's Guide lists the
modules available.  Additional detailed information  on the models used in the system  is also
available.

       National Status  and Trends for Marine Environmental Quality'(NS&T)
       The Alaskan Marine Mammal Tissue Archival Project
       The National Marine Mammal Tissue Bank
Description

       The National Institute of Standards and Technology began its specimen banking activities
in 1979 as a pilot program to  investigate the feasibility of long-term storage of environmental
samples. Specimens are collected and archived to provide well preserved and documented samples
for retrospective  analysis  as analytical  techniques improve  or  as  concerns about previously
unidentified  pollutants arise.  Since storage space in a long-term archive is limited, tissues that tend
to concentrate the analytes of interest are selected. Therefore, human liver specimens were selected
as the first sample type to be included.  Environmental specimen bank activities at NIST have
expanded beyond  the pilot program to include samples from the marine environment (sediments,
oysters, mussels, and fish tissue) and marine mammal tissues. Each of these banking projects are
supported by various government agencies in  conjunction with NIST.  Over 10 years of practical
experience in specimen banking within the NBSB has demonstrated that the concept of long-term
storage of environmental specimens is feasible. Although the total scientific value of the banked
samples is not fully known at this time, the current uses  of  the  banked  samples and the
implementation of the concept has already contributed  to major monitoring programs in the U.S.
and abroad.  Even through the types of specimens and the number of samples collected are limited,
the NBSB can serve as a valuable resource for the assessment of long-term trends  of pollutants
affecting human and environmental health.

-------
                                    DATA SOURCES

       In conjunction with other government agencies, NIST maintains four specimen bank
projects:  the National Environmental Specimen Bank, the National Status and Trends Specimen
Bank, the Alaskan Marine Mammal Tissue Archival Project, and the National Marine Mammal
Tissue Bank.

       The National Environmental Specimen Bank is supported by the Environmental Protection
Agency (EPA) in conjunction with NIST. Human livers are archived in this bank at NIST of which
approximately twenty percent are  analyzed for selected  organic  and inorganic  constituents.
Approximately 600 liver specimens have been collected since 1980. Research related to specimen
banking is also done. See the database description in Part I of this Inventory for a full description
of the program.

       The National Status and Trends (NS&T) for Marine Environmental Quality is a monitoring
program sponsored by NOAA  designed to  determine the environmental quality of U.S. estuarine
and coastal waters.  In this program,  sediment, fish tissues (muscle and liver), and bivalve molluscs
(muscles and oysters) are collected from 50-150 U.S. coastal sites. In 1985, NOAA, in conjunction
with NIST, incorporated specimen banking into their NS&T program.  Approximately 10 percent
of these  marine samples are stored at NIST for  specimen  banking  purposes.   See  the database
description in Part I of this Inventory for a full description of the program.

       The Alaskan Marine Mammal Tissue Archival Project was initiated in 1987 by NOAA; the
U.S.  Department  of the Interior,  Minerals  Management Service; and NIST to establish  a
representative collection of tissues from Alaskan marine mammals for future contaminant analyses
and documentation of long-term trends in environmental quality. See the database description in
Part I of this Inventory for a full description of the program.

       The National Marine Mammal Tissue Bank was initiated in 1990 by NOAA, in conjunction
with NIST. This program is similar to the Alaskan Marine Mammal Tissue Archival Project except
that it focuses on the 48 contiguous states of the U.S.  See the database description in Part I of this
Inventory for a full description of the program.
                                 DATA PRESENTATION

       Activities of the National Environmental Specimen Bank component of NBSB to date are
 described in four journal publications (see separate entry for National Environmental Specimen
 Bank; Reports section). Data presented include sampling and storage protocols developed by NIST
 for archived specimens, effects of various storage conditions, analytical procedures used to detect
 selected contaminants, and analytical results. Bar and line graphs are  used to illustrate sampling,
 analytical, and storage parameters. Tables are used to present analytical results.

       NS&T data are contained in over .200 publications, reports, presentations, and technical
 memoranda; at least one of which describes the NS&T specimen banking activities.

       National Coastal Pollutant Discharge Inventory (NCPDI)
       National Status and Trends for Marine Environmental  Quality (NS&T)
       National Shellfish Register of Classified Estuarine Waters (Register)
Description

       The NEI was initiated in 1983 to develop a national estuarine database as part of NOAA's
program of strategic assessments of the Nation's coastal and oceanic resources.  A spatial
framework was created for NEI so the database could be used in several related NOAA projects.
The estuarine drainage area (EDA), defined by NOAA as that portion of a watershed that most
directly affects an estuary and is delineated by U.S. Geological Survey (USGS) cataloging units and
by the head of the tide, is the spatial unit used in all NEI projects. NOAA's NCPDI, NS&T, and
Register programs use the NEI framework, as do other NOAA projects on eutrophication, marine
organisms, and wetlands.  Together, these data provide NOAA with a national estuarine assessment
capability.

       NEI includes physical and hydrologic characteristics (estuarine and fluvial drainage areas,
water surface area, volume, tidal range, salinity regime, and freshwater inflow) and land use and
population growth data for each EDA.  The physical and hydrologic characteristics help define the
ecological processes and habitats within an estuary and determine  how human activities affect an
estuary's overall condition. The type and extent of certain land uses and the pattern of population
growth are partial indicators of the pollutants entering estuarine waters and the extent to which the
environment of the surrounding drainage basin is  altered.

       The physical and hydrologic characteristics  of each estuary were used by NOAA to develop
a classification index to approximate the ability of an estuary to retain pollutants.  The index has
been used with estimates of nitrogen and phosphorus loadings from the NCPDI to identify estuaries
that may be most sensitive to changes in nutrient  inputs.

-------
                                     DATA SOURCES

       In most cases, EDAs coincide with hydrologic cataloging units of the USGS.  An EDA
includes all or part of the cataloging unit containing the most upstream extent of tidal influence.
Depending on the complexity of coastal drainage patterns, certain cataloging units were modified
to eliminate the portion of the drainage area not draining directly to estuarine waters.  Fluvial
drainage areas (PDAs),  the land and freshwater portions of watersheds upstream of EDAs, always
coincide with hydrologic  cataloging  units  of  the  USGS.   Estuarine water surface  area  is
approximated at  mean  tide level; this information  is needed to estimate an estuary's volume,
flushing rate, and pollutant susceptibility.  The volume of an  estuary and freshwater inflow help
determine its ability to dilute pollutants. Freshwater inflow statistics were estimated for gaged and
ungaged areas  of an estuary's watershed.   For gaged  areas, data were compiled from USGS
streamflow gage records and from records of significant flow diversions not accounted for in USGS
data. For ungaged areas, NOAA precipitation data were used to estimate freshwater runoff and
direct precipitation to an estuary.  Population growth data was obtained from the USGS (USGS
obtains population data from the U.S. Census Bureau). .Land use data was primarily obtained from
the Land Use Data Analysis (LUDA) program of the USGS (see entry for NCPDI), which compiles
data for 40 different types of land use in the United States. Other sources, such as the National
Resources Inventory of the U.S. Soil Conservation Service; the Bureau of the Census; the Census
of Agriculture; and state, regional, and city planning agencies were also used. The result was a set
of consistent land use estimates in acres that are  used in NEI  and other NOAA databases.
                                 DATA PRESENTATION

       The cornerstone of the NEI is the National Estuarine Inventory Data Atlas,  Volume 1, which
identifies 92 of the most important estuaries and subestuaries of the contiguous United States and
presents the physical and hydrologic characteristics  of each estuary through maps and tables.
Volume 2 presents area estimates for seven categories and 24 subcategories of land use as well as
1970 and 1980 population estimates in tables.  Land use data are compiled for three spatial units:
the EDA, USGS hydrologic catalog units,  and counties that intersect EDAs. Population estimates
are compiled for EDAs only. Other volumes in the atlas series include information on wetlands
and outdoor public recreation facilities in EDAs.

       Numerous technical reports about the Nation's estuaries have been produced. These include
a Supplement Series, which identify estuaries in addition to those in Volume I of the Atlas Series
and indicate the methodology used to further refine salinity zones. Tables,  graphs, and maps are
used to present some of the data in these reports.
                                  DATA AVAILABILITY

Level of Data Aggregation:  Individual data entries and summary statistics are available on specific
       estuaries; NEI data aggregation is consistent with other NOAA databases which use the
       NEI framework

       Permit Compliance System (PCS)
       Storage and Retrieval of Water Quality Data (STORET)
       Toxic Release Inventory (TRI)
Description

       RPA software links the following national data files:  the file of Section 304(1) short list
information, the Toxic Release Inventory (TRI), the Storage and Retrieval of Water Quality Data
(STORET), the River Reach File, and the Industrial Facilities Discharge File. RPA allows the user
to readily access these multiple data systems and produce a variety of reports and listings comparing
facility discharges, water quality stations, and regulatory criteria. No effort is made to calculate in-
stream concentrations or to determine whether violations  of state/EPA criteria have occurred.
listings allow the user to determine the geographic relationship of discharge facilities and water
quality stations.

       RPA is designed to address the requirements under Criteria 7 of Section 304(1) of the Clean
Water Act:   identification  of the  state's waters with likely presence of  307(a)  priority  toxic
pollutants.  This data system  allows users to generate  reports needed for the triennial  review
requirements  associated  with  standards  setting.  RPA may help  to  establish a  permanent link
between the monitoring and standards programs and enable state toxics  control programs to build
upon new monitoring information  and new EPA criteria recommendations as  they become
available.
                                     DATA SOURCES

       Information on the geographic relationship of the various components of RPA are based
 on an electronic version of the 54,000 base maps of the U.S. Geological Survey, also known as the
 7.5-minute quadrangle maps. These maps portray features at the 1:100,000 scale. The hydrologic
 data from these maps are stored separately as the River Reach File.  This file includes over 100
 million records containing the latitude and longitude coordinates of streams, lakes, reservoirs,
 estuaries, and shorelines  in  the United  States.   The latitude/longitude,  stream reach cross
                                           11-27

-------
 references, and population of cities in the United  States,  are  also included in the mapping
 component of RPA.

        Information on water comes from two sources:  the Storage and Retrieval of Water Quality
 File (STORET) and the Permit Compliance System (PCS). Detailed information about these data
 systems can be found in the first section of this Inventory.

        STORET contains geographic and other descriptive data about the sites where water quality
 data have been collected.  Data include physical characteristics and chemical constituents of the
 water,  fish tissue,  or sediment sampled.  This file contains over 200 million water sampling
 observations.  (Information about the flow in the stream is stored in the Stream Gage  File.)

        The PCS database is  the national inventory for EPA permit issuance  and compliance/
 enforcement data. The database consists of more than 5 million records on over 75,000 active water
 discharge permits.  Information about the facilities is stored in the Industrial Facilities  Discharge
 File.   This file does not  contain measurements,  but it  does  contain information on indirect
 dischargers to sewage treatment plants, standard industrial classification codes, receiving stream,
 and categorization of industrial process.

        Information  on  estimated industrial facility discharges  to water  comes from  the Toxic
 Release Inventory  (TRI).  TRI contains data on annual estimated releases of over 300 toxic
 chemicals to air, water,  and land by the manufacturing industry.  Information includes amounts of
 chemicals stored on site, estimated  quantities of chemicals released, onsite source reduction and
 recycling practices, and estimated amounts of chemicals transferred to treatment, recycling, or waste
 facilities.  Detailed information about this data system can be found in Part I of this Inventory.


                                  DATA PRESENTATION

        RPA provides the user with a variety of listings and reports.  RPA can be used to identify
 the number of water quality stations, industrial facilities, and publicly owned treatment facilities in
 an area, as well as the probable chemicals of concern for this area based on the TRI  estimated
 discharge data.  Further, it can be noted whether the EPA and the state have existing  criteria to
 cover the  potential  pollutants.  Based on the TRI and on the National Pollutant Discharge
 Elimination System (NPDES) permits issued to facilities in the area, a list of predicted  pollutants
 by  river segment can  be generated.   No  effort is made, however, to  calculate  in-stream
 concentrations or to determine whether violations of state/EPA criteria have occurred.   Detailed
 reports  of measurements by pollutant by water quality site for given periods of time, sediment
 analyses, and fish tissue samples can be generated.

       RPA can also be used  to produce a map of the locations of water quality stations, direct
 industrial dischargers, and municipal sewage treatment plants  in a given area.

       RPA is available through the EPA National Computer Center and communications network.
The user interface is interactive with a question/response format. The User's  Guide lists example
programs used to generate  a variety of output formats.

Description

       SEEDIS is a research and development project at the Lawrence Berkeley Laboratory,
supported by DOE, DOL, and others.   Policy formulation, implementation, and management
depend on accurate, timely information.  The SEEDIS Project addresses these information needs
by providing a unified framework for data management, information retrieval, statistical analysis,
and graphic display of data from a collection of databases for various geographic levels and time
periods, drawn from the U.S. Census Bureau, the U.S. Environmental Protection Agency (EPA),
and the U.S. Department of Health and Human Services. SEEDIS contains information on census,
energy, environment,  geography, health, population characteristics, and socio-economic  status.
SEEDIS allows the user to produce graphical and map presentations of analyses of combinations
of these data for a variety of geographic levels  and scope.

       SEEDIS was initiated in 1972 by DOL as a demonstration project to link data from multiple
sources. Since that time, the project has been expanded. DOL, DOE, EPA, and the Army Corps
of Engineers  have used the system for a variety of needs. SEEDIS is currently available through
computer  systems of DOL, DOE, and EPA.


                                   DATA SOURCES

       SEEDIS contains information from a wide range of data systems - over 200 systems with
over 7 billion data values. The amount of information differs between geographic levels due to the
characteristics of the source data system.  In general, data are available at the county level as well
as state and national levels. Some data are available at the level of Census tracts and Standard
Metropolitan Statistical Areas (SMSAs). The list that follows contains only some of the values
available  through SEEDIS.   (The  environmental exposure  information is derived from  air
monitoring station data available through AIRS.)
                                         11-30

  CENSUS INFORMATION

  i non  JLEEDIS includes data on population size by major racial and ethnic groupings for 1970 and
  1980.  These data are variously available at the national, state, county, city, and census tract level.

  ENERGY INFORMATION

        SEEDIS contains information on  electrical generating capacity for 1960 through 1995
      CA^r T6^1? 1C at thC nati°na1' °°Unty'  and standardized metropolitan statistical  area
  (5>MbA) level.  The data system  also contains 1970 residential housing data, and heating  energy
  requirements in 1970, and biomass resources for 1976 and 2025 at the county geographic level

  ENVIRONMENTAL INFORMATION

        Data on air quality measurements for criteria pollutants are available for 1974 through 1976
  at the census tract level. The data are derived from the AIRS data system (formerly SAROAD}
  Assessments include total suspended particulates (TSP), sulfur and nitrogen dioxides, photochemical
  oxidants, ozone, carbon  monoxide, sulfates, and total and nonmethane hydrocarbons  For each
  pollutant, county estimates  of pollutant concentration (at  the position of the county population
  centroid) were calculated as the weighted geometric means of measurements from nearby stations
 including stations in nearby counties.  The location of the air quality monitoring stations  is  also
 available from the National Air Monitoring Stations (NAMS) data system.

 GEOGRAPHIC INFORMATION

        Data on the centroids of the 1970  household populations are available for a variety of
 geographic  levels.  The areas, centroids, and boundaries  of census tracts and counties  are also
 included.

 HEALTH INFORMATION

       Data on age-,  sex-, and race-specific total mortality are available for geographic levels as
 sma 1 as counties for the years 1969 through 1984. In addition, total annual leukemia mortality is
 available  Cancer incidence for 1973 through 1981 from the Surveillance, Epidemiologic, and End
 Results (SEER) registers is included for the states that participate in the program.

 POPULATION INFORMATION
*t,        nn    no   sex-sPecific population counts (from the 1980 Census) and estimates for
the years 1950 to 1987 are available for varying geographic levels.  Estimates are available from a
variety of sources.

SOCIO-ECONOMIC INFORMATION

       Labor force, employment  by  industry,  income,  education, fertility, and  the  Census  of
Agriculture are a few of the many  county- and state-specific data available through SEEDIS.

                                 DATA PRESENTATION

       SEEDIS is available through several computer systems at DOE, DOL, and EPA.  It uses
an interactive, user-friendly format to guide the user through selecting geographic level and scope,
extracting or transforming data, and displaying the results. Users can extract data and export these
data to other computers,  or load data from external sources.

       Numerous mapping and other display options are available. Maps can display one or two
variables and be generated  at all geographic levels.  In addition, special symbol  maps can be
generated where symbols  of varying size indicate the information specific to given locations.  Charts
include bar, pie, and line charts. Some special charts available include fuzzy bar charts (that use
fuzzy set theory to combine several imprecisely  specified parameters), overlaid line charts, two-
dimensional bar charts, and tables with variable sized symbols to impart relative value information.
The ability to print these displays depends on  the equipment available  at the user's computer
facility.

                     Related Data Systems that Support and Quantify
                           Environmental Exposure Assessment
       In the course of identifying databases  that contain measurements  of toxicants in the

environment, several data systems  were identified in which information not directly based on

analytical measurements of toxicant concentrations is provided to assist the user in further assessing

exposure.  Examples of such information include fate and transport models, emission factors, and

surveys of consumer use of products or consumption of food. For example, emission factors based

on source categories such as those provided in the Crosswalk/Air Toxics Emissions Factor Database

Management System can be used to  estimate ambient levels bf pollutants in the vicinity of a known
industrial point source.  Similarly, information from the Nationwide Food Consumption Survey can

be coupled with the analytical information in the Total Diet Survey (described  in Part I of this

Inventory) to estimate exposure to food contaminants.  In some instances, the data in these systems

are derived from measured observations;  in other instances, the data are derived from models. This

Appendix  lists these data systems and summarizes the information provided by the data system

managers.  (This Appendix, however, is  not a comprehensive or systematic survey of this type of
data system.)

and to study how diets vary over time for individuals and groups of individuals.  The  Survey is
conducted between the larger Nationwide Food Consumption Surveys (MFCS, also described in this
Appendix), which are  conducted every 10 years.

       The CSFII obtains information on food intake from six 24-hour recall periods collected by
an interviewer at approximately 2-month intervals during the year.  Persons are selected based on
a multistage stratified area probability sample to represent the sex and age distribution of persons
residing in private households in the 48 contiguous United States. An additional sample is selected
to provide data representative  of persons in private households with incomes at or below 130
percent of the poverty guidelines. Special surveys have been conducted that focus on women of
reproductive age, children, and adult men.

users to develop their own scenarios for estimating potential dose rates from deposition of a film
or liquid onto skin and from contact with solid surfaces.  The model  does not include estimation
based on absorption.  The user provides the weight-fraction of the chemical of interest in the
consumer product and the program calculates potential dose rate. The data system also provides
default values for chemicals in common consumer products.


Summary of Environmental-related Information:

Media:  Water, soil

Classes of compounds: User provides weight-fraction of the chemical in the product

Relevant variables:  Concentration of chemical in liquid or solid

Process evaluated:  Dermal contact with consumer products


Database Availability:

Availability: Any requestor can obtain diskettes and user guides

Form: The software was  designed to be user friendly  and to require a minimum number of user
      inputs so that screening-level estimates of potential dose rates from dermal contact can be
      generated rapidly. DERMAL is programmed in Turbo C++ and is designed  to run on a
      personal computer using a PC-DOS/MS-DOS version 3.0 or later equipped with 80 K of
      available  system memory.

Description:

       DRES is a tool for estimating dietary exposure to a pesticide and comparing that estimate
to a previously  determined Reference Dose.  The exposure estimates are derived  from food
consumption of "raw  agricultural  commodities."   These estimates  are made by  translating
information  from the Nationwide  Food Consumption Survey (MFCS) conducted by the U.S.
Department of Agriculture (see description in this Appendix). The translation is performed using
"recipes."   The  program can multiply the exposure  by an estimate of the upper bound of
carcinogenic potency to provide an  estimate of upper bound carcinogenic risk over a lifetime.

       DRES is composed of three major files containing information on food  consumption
estimates, toxicology summaries for each chemical, and residue concentrations  for each chemical
in specific foods.

       DRES is routinely used to  estimate  dietary exposure for the U.S. population and for 22
subgroups of the population.  Dietary exposure is expressed as  mg/kg body weight/day and as a
percentage of the Reference Dose,  where applicable.

Description:

       The EFDB contains files of physical/chemical properties and data on the environmental fate
of chemicals, including data on biodegradation. The EFDB allows rapid access to all available fate
data on a given chemical without having to search the primary literature.  The database provides
data for constructing structure-activity correlations for degradability and transport of chemicals in
the environment.  These correlations help identify persistent chemical classes as well as physical or
chemical properties that may correlate to particular behavior in the environment. ,

       Information is ordered by Chemical Abstract  Services Registry  Number  (CASRN).
Approximately 17,000 references were used as the source for the information in the database. (Full
citations are given in the XREF file, a bibliographical listing of references.) The database consists
of four major files:  DATALOG, CHEMFATE,  BIOLOG, and BIODEG.

       DATALOG contains approximately 160,000 records ;on approximately 12,000 chemicals.
The file indicates where environmental fate and exposure data can be found, using 18 different
indexing terms (e.g., water solubility, Henry's Law constant, and ambient  monitoring).

       CHEMFATE contains actual physical property values,  rate constants, and monitoring
concentrations for approximately 900 commercially significant chemicals. Recommended physical
property values were collected for the SARA Section 313 Toxic Release Inventory chemicals and
the chemicals included in the Superfund Health  Evaluation Manual.

       BIOLOG indicates sources of microbial toxicity and biodegradation data on approximately
6,000 chemicals. Indexing and searching are allowed on toxicity or biodegradation data; aerobic or
anaerobic conditions; pure enzyme, cell free extract, pure culture,  or mixed culture conditions;
source of microorganisms  (e.g., soil, sewage, etc.); and whether the metabolism pathway has been
studied.

       BIODEG contains experimental results  on biodegradation studies for approximately  600
chemicals.   Experimental details, such as chemical concentration and rate of  degradation,  are
included.

Description:

       FLUSH is a software program developed for estimating surface water concentrations of
chemicals that come from consumer products which were disposed of in household wastewater.
This household wastewater is assumed to undergo treatment at a local wastewater treatment facility
that subsequently discharges  its treated effluent into surface waters.   FLUSH also  provides
estimates of potential dose rates for humans from ingestion of drinking water and for fish that may
become contaminated by these household wastewater releases. The model does not use absorption
parameters for the estimation.  The results of the model can be compared with concentrations of
concern for aquatic organisms  so that the potential effects of household wastewater releases on
aquatic life can be predicted.

 Description:

       The SCIES model has been developed to assist the Exposure Evaluation Division of the
 Office of Pollution Prevention and Toxics in performing screening-level assessments of potential
 dose rates from  inhalation of new and existing chemicals  in  consumer products.  The model
 classifies consumer products in 10 categories and estimates potential average individual dose rates
 from inhaling each component of a consumer product based on the product category in which it
 has been placed.  The model estimates potential dose rates for both  the user of the product and
 passively exposed nonusers (i.e., individuals present in the residence who are not actively using the
 products).  Default values are provided for each parameter required to run the model for each of
 the product categories.   The assessor has the option of  changing selected default values.  An
 additional'option allows assessors to create their own scenarios.

       The SCIES model combines the results of a recently completed effort to measure ventilation
 flows within residences using a perfluorocarbon tracer (PFT)  with a two-zone mass balance model
 to allow estimation of potential dose rates to both users and nonusers.  Scenarios are provided that
 depict product uses expected to result in reasonable worst-case  estimates of potential dose rates.
 These worst-case  scenarios form the basis for the default values used.

                Listing of Chemicals by Data Collection System and Media

       This Appendix lists the chemicals for which information is available in the database
 collection systems described in Part I of this Inventory. For each chemical, the list indicates
 which database(s) contain information  and for what media.  It should be noted that the
 chemical names were entered as they were provided; they were not edited for consistency of
 nomenclature or format.

       Lists were obtained  for all but two of the data collection systems:  Lake Analysis
 Management System (LAMS), and the Pesticide Information Network (PIN). In addition, it
 should be noted that the lists for both the Air Facility Subsystem (AFS) of the Aerometric
 Information Retrieval System (AIRS) and the Air Quality Subsystem (AQS) of the Aerometric
 Information Retrieval  System (AIRS)  are both listed under  the  Aerometric Information
 Retrieval System (AIRS).

       The media categories are air, water, soil, food, bulk chemicals, human samples, and
 other. As indicated in the questionnaire, these categories include the following subcategories:


       »     Air: indoor homes, indoor  public, outdoor urban, outdoor rural, emissions,
             personal monitor, other;
       •     Water:  surface, ground water, leachate, municipal, private, other;
       •     Soil:  residential, industrial, sediment, Superfund Site, dust, other;
       •     Food sources:   nondomesticated gamebirds  and mammals,  domesticated
             gamebirds and mammals, plants, and other;
       •     Bulk chemicals:  bulk chemicals, other;
      •     Human samples: human samples (e.g., blood, urine).

Respondents used the  "other" category to include such media as mixed hazardous waste,
materials injected into underground wells, materials discharged to Publicly Owned Treatment
                                         E-l

-------
Works (POTWs), wastes at recycling and treatment facilities, and wildlife that  does not
constitute a food source for humans (e.g., starlings).

       For the most part, the names of the data collection systems are provided in full in the
chemical list. However, some of the database names were so long that including the entire
name enlarged the-size of the database unnecessarily.  Therefore, for a select number of
databases, the acronym was used instead of the full name. Table E-l on the next page lists
the data collection systems for which chemical names are listed and indicates which databases
are listed by their acronym. The list itself is on a diskette accompanying this document.

    Access to nheminfll  List;   The  enclosed diskette contains a  dBASE HI PLUS® file
containing the chemical listing from Appendix E.  The file contained on the diskette is
compressed so that it can fit onto one diskette.  To access the list requires a hard disk with
at least 1Q megabytes of free space. The data base can be installed on any drive and in any
directory; however, the file will be loaded into the current directory in use once your activate
the software enclosed.  We recommend that it be installed on the your dBASE directory for
ease of access from that software. The following  procedure can be used to install this file
within the dBASE directory and it assumes you are installing the  database on the C drive.

       1.    ' Place the database disk in your computer's A drive.
       2.     At the C:  prompt change your directory to that in which your dBASE  III
             PLUS software is contained.
       3.     At the dBASE prompt  type AiCHEMICAL and press the ENTER key.
       4.     A dBase ffl PLUS® file (CHEMICAL.DBF)-will be copied from the floppy disk
             to the hard disk.
       5.     Remove the floppy disk from the A  drive.
       6.     Once.the data file has  been copiedj  the data base may be accessed using the
             dBase HI PLUS software program.
