1.0 EXECUTIVE SUMV&RY
Background
Cne of EEA's priorities is to determine the extent of pesticides
occurring in the nation's ground water. While many individual, localized
ground-water monitoring studies have been conducted across the country, there
has been no comprehensive compilation of these results. In response to this,
the U.S. Environmental Protection Agency, Office of Pesticide Programs, has
developed the Pesticides in Ground Water Data Base. The data base contains
information derived from monitoring studies conducted by pesticide
registrants, universities, and government agencies. The data base identifies
the pesticides that have been looked for in ground water, the areas that have
been monitored, and the pesticides that have been detected. The data base was
developed in the first quarter of 1988, and at the same time, a public docket
was established so interested parties could have access to the source
information.
Following the development of the data base, the Agency has been
conducting a program to assess the validity of the information it contains.
The program involves contacting the author or director of each monitoring
study and requesting that they review and confirm our interpretation of the
information. The authors are being requested to identify the source of
contamination for each reported detection and document the laboratory
analytical methodology used to quantify the results. At this time, we believe
we have gathered sufficient information to provide the public with an interim
report on the national status of pesticide residues in ground water.
Results
To incorporate the scientific rigor and quality assurance we have
instilled in this program, the results are presented in several categories
based on the confidence we have in the information. Many of the reported
detections have not been confirmed, and some of the contamination is from
unknown sources. However, we consider all of this information important, and
have segregated the data accordingly.
1-1
-------
We have tried to distinguish point-source contamination from pesticide
occurrence in ground water resulting from leaching through the soil profile
following normal agricultural applications. In general, point-source
pollution refers to water pollution caused by discharges into receiving waters
from the end of pipelines, localized spills, or other identifiable "points".
We have broadened this definition in presenting our results to include
documented misuse (i.e., use on a crop or in areas for which it is not
registered) as well as conventional point sources such as spills or well
contamination by direct channelling.
Each entry in the data base has been assigned a rating reflecting the
quality or confidence in the results. Studies that have been conducted under
sound documented protocols where the results have been confirmed by acceptable
analytical techniques are assigned the highest rating of confirmation. Lower
ratings are assigned to studies in which the protocols are less poorly
documented and analytical confirmations are less reliable.
A total of six categories have been, designed to present the results, but
three categories are given particular attention. Category 2 includes all
information collected to date - excluding data known to be of poor quality and
data that is from known point-source contamination. Category 5 includes
information that has been derived from scientifically confirmed studies where
the contamination is attributed solely to normal agricultural use. Category 6
includes confirmed information attributed solely to known point sources or
documented misuse. Tne results from these categories are given below:
Number of Number of
Category Pesticides States with
Detected Detections
2. All data excluding data of 74 38
known poor quality and known
point sources or misuse
5. Confirmed data attributed 46 26
to normal agricultural use
6. Confirmed data attributed to 32 12
point sources or misuse
1-2
-------
Hie results frcm categories 2 and 5 are depicted on a map of the united
States in Figure 1-1. Table l-l presents a summary of pesticides that have
confirmed detections in ground water attributed to normal agricultural use
(category 5) and point sources or documented misuse (category 6). This table
also illustrates whether the pesticide has been included as an analyte in the
National Pesticide Survey, the number of states in which each pesticide has
been detected, the range of concentrations detected, and the proposed EPA
Health Advisory for the pesticide.
Because many of the studies in category 2 have not yet been confirmed and
the unknown sources may be the result of normal agricultural practices, we
believe that the precise representation of the national status of pesticide
residues in ground water as a result of normal agricultural application is
greater than category 5. It is important to note, however, that one or two
detections of a pesticide at trace levels, does not indicate a problem in
itself. However, a particular pesticide detected at numerous locations at
concentrations equal to or greater than Health advisory levels is reason for
concern. For this reason, it is critical to look at both the frequency of
detections and their concentrations, and how those concentrations ccnpare to
established and proposed health numbers for a specific pesticide before
drawing conclusions on the severity of the problem.
Caveats on Using the Data ffiVffi
Ihere are dangers in trying to use Figure l-l to indicate the statistical
significance of the problem on a national level. Many of the studies were
only designed to sanple vulnerable ground water or to investigate suspected
problems, while other studies were designed to be statistically unbiased. It
is important to note that the studies have not been limited to drinking water
supplies and some studies have sampled many types of wells including wells
used only for observation or irrigation. Many of the studies have
concentrated on shallow ground water which may not be representative of the
drinking water sources of the area. As such, the results cannot be used to
estimate human exposure to pesticides in drinking water.
Pinpointing the source of pesticide contamination is perhaps the most

difficult parameter to confirm in the data base. Contamination can result
from causes other than leaching through the soil profile following normal
field applications. These causes include: iuproper pesticide disposal,
accidental spills, rinsate from equipment maintenance, human error in mixing,
intentional excess applications, back siphoning into a well during
chemigation, or direct channelling of pesticides through poorly constructed or
damaged wells. It is difficult to conclude with confidence that ground-water
contamination is the result of leaching from normal agricultural use, unless
the above factors can be excluded.
Use of the Data Base bv EF&
The data base will be used by the Agency to supplement the regulatory
process for pesticides. It is being used to target pesticides that are
contaminating ground water and establish priority candidates for regulation to
mitigate such problems. The data base is being used to help identify the
migration pathways and environmental factors associated with contamination
which are the first steps in developing mitigation strategies. It will also
be used to highlight vulnerable areas for which reduced applications or other
restrictions may be warranted, and to depict data gaps where additional
monitoring should be conducted. In addition, the data base can be used in
support of the reregistration of a pesticide for which ground-water
contamination has not been shown to be a problem. Tne importance given to the
data base in these functions will increase as the data base evolves.
With over 50 percent of the nation's population relying on ground water
for their drinking water source, we cannot underestimate the seriousness of
pesticides occurring in ground water. To address this problem, the Agency has
many additional ongoing programs. ETA has developed an Agricultural Chemicals
in Ground Water Strategy tx> delineate the appropriate federal and state roles
and minimize the risk for future ground-^water contamination. In addition, the
National Pesticide Survey is being conducted to sample drinking water wells
throughout the country to statistically assess the occurrence and levels of
pesticides in drinking water,wells. This type of statistically designed study
is more appropriate for assessing human exposure to pesticides in drinking
water than the Pesticides in Ground Water Data Base. As part of the National
1-7
-------
Pesticide Survey, Health Advisory levels have been developed for 62
pesticides. Tfie Agency has also developed a ground-water training module to
educate certified applicators about preventing ground-water contamination.
Ground-water monitoring studies are being required of registrants for the
initial registration of chemicals and the reregistration of existing
pesticides whose physicochemical properties indicate that they may persist in
the environment and are likely to leach to ground water. For some pesticides,
these programs have resulted in cancellations or voluntary withdrawals, the
denial of new registrations and reregistrations, label statements to restrict
application rates, restrictions on use in vulnerable areas, designation as a
restricted-use pesticide, or Special Reviews (e.g., aldicarti).

2.0 IMTCDUCTICN
2.1 Background
Prior to the late 1970's, ground-water contamination from field-applied
pesticides was almost entirely unexpected - primarily because soils were
thought to behave as natural filters, and pesticides were assumed to degrade
or volatilize rapidly. The discovery of aldicarb in 96 wells on Long Island
(in 1979) and EBCP in over 2000 wells in California (from 1979-1982) focused
attention on pesticides used in agriculture as potential ground-water
contaminants. By the early 1980's, several incidents of ground-water
contamination resulting from the field application of pesticides had been
confirmed. Since then, increasing numbers of pesticides have been detected in
ground water in an increasing number of states (Cohen, et. al, 1984; Cohen,
et. al, 1986; and Holden, 1986). In 1987, the U.S. Environmental Protection
Agency documented 19 pesticides occurring in ground water from 24 states
attributed to agricultural practices (EPA/OPTS, 1987).
2.2 Pesticides in Ground Water Pgfca Base
Many localized, individual ground-water monitoring studies for pesticides
have since been conducted across the country; however, there has been no
comprehensive compilation of these results to assess the nature and scope of
pesticide residues in ground water. In response to this, the Environmental
Protection Agency, Office of Pesticide Programs, Qn^raranental Fate & Effects
Division has developed the Pesticides in Ground Water Data Base. The data
base contains the results of monitoring studies conducted by federal and state
agencies, chemical manufacturers, and universities. These results have been
obtained frcm published literature and through direct correspondence to the
Agency. The data base identifies the pesticides that have been looked for in
ground water, the areas that have been monitored, and the pesticides that have
been detected. It has not been the intent of the data base to maintain a
record of every sample that has been collected and analyzed for pesticide
residues. The data base represents summary results (e.g., number of wells
sampled, number of positive wells found, and the ranges of concentrations) for
2-1
-------
monitoring studies that have been conducted. To the extent possible, these
results are itemized down to the county level and by origin of contamination
(e.g., point source vs. leaching due to agricultural application). Hie data
base was developed in the first quarter of 1988, and at the same time, a
public docket, containing the original source of information for every entry
in the data base, was established so interested parties could have access to
the information. The following contact is given for additional information on
the public docket:

Telephone: (703) 557-2805
The data has been obtained from many different studies that have not been
conducted under a single standardized protocol. In order to minimize the
misuse of poor quality data, the Agency has been conducting a program to
assess the validity of the information in the data base. This program
includes contacting the author or director of each monitoring study to request
that they confirm our interpretation of their data, fill in missing
information, and document the laboratory analytical methodology used to
quantify the results.
A. status report on pesticides in the nation's ground water is presented
in the following sections. Section 3 presents assessments made from the data
base. Included in Section 3 are summaries of the number of pesticides found
in ground water and the number of states in which they have been detected.
Additional results are presented for data that has been confirmed to date.
Conclusions arc given in Section 4 along with appropriate caveats for using
the data. This section discusses how the Agency will be using this data in
the future. References are contained in Section 5, and background information
on both the data base structure and the data confirmation program are given in
Appendix A. Data listings and other summary tables are included in Appendices
B through F.

3.0 ASSESSMENTS WITH THE EKEA. BASE
3.1 &??^^aU*^l ft Categories
Over 70 different pesticides have been reported in ground water in nearly
40 states; however, many of the reported detections have not been confirmed,
and some of the contamination has resulted from unknown sources. The results
are presented in six categories in order to differentiate normal agricultural
use from point-source contamination and to reflect the confidence we have in
the information. Hie results range from assessments based on all data in the
data base to assessments that only include data that has been confirmed and
attributed to a single source of contamination. The categories are presented
and defined in Table 3-1.
Three of the categories are given particular attention. Category 2
includes all information collected to date, except data known to be of poor
quality or data where the contamination has been documented as being due to
point sources or some mechanism other than field leaching due to agricultural
application. Category 5 includes information that has been derived from
scientifically confirmed studies where the origin of ccntamination is
attributed solely to normal agricultural use. Category 6 includes information
confirmed from studies where the contamination is attributed solely to known
point sources, direct well channelling, or uses in a manner for which they
have not been registered (i.e., misuse).
3.2
An inventory of pesticides that have been detected in ground water from
these six categories is presented in Table 3-2, The table indicates the
number of pesticides that have been found in ground water and the number of
states in which pesticides have been found. These summaries are expanded in
Tables 3-3 and 3-4. Table 3-3 illustrates the number of pesticides that have
been reported in ground water for each state. Table 3-4 presents the number
of states in which each pesticide has been detected. Table 3-4 also footnotes
which of the pesticides have been cancelled or have had their use severely

restricted.
Table 3-5 presents a sunroary for pesticides that have been detected in
ground water due to normal agricultural use (category 5), point sources or
misuse (category 6), and unidentified sources. This table only incorporates
data that has been confirmed by the Agency to date. The table identifies
which pesticides have been confirmed, the states in which they have been
found, and their maximum and "median" concentrations in ground water. In this
table, the median concentration is represented as the median of the average
concentrations from each study included in the category (where the average
concentration is calculated as the mean of all positive detections in a
study). If a single study comprises the category, the median concentration is
represented by the average concentration for the study. If the category is
comprised of a single well, than the average concentration for that well is
given. The table also indicates the proposed Health Advisory level for the
pesticide, whether it has been included as an analyte in the Agency's National
Pesticide Survey, and whether the pesticide has been cancelled or severely
restricted. The results from categories 2 and 5 are depicted on a map of the
United states in Figure 3-1.
3.3 Comparisons to Previous Assessments
Table 3-6 compares the results of these six categories to several other
recent assessments of pesticides in ground water in the United States. The
first study presented (EPA/OPTS, 1987) is an update to earlier assessments
presented by the Agency in 1984 and 1986 (Cohen et. al, 1984; Cohen et. al,
1986) before the data base was formalized. The second study (Parsons and
Witt, 1988) was conducted at Oregon state University, Department of
Agricultural Chemistry and presents the results of a mail-in survey with lead
state agencies. The third study was conducted by the U.S. Public Information
Research Group (U.S. PIRG) in the summer of 1988 using EPA's public docket
(Hind and Evans, 1988). The results from these three studies are presented on
maps of the United States in Figures 3-2 through 3-4, respectively.
Discrepancies between the assessments are based on the data available to
the researchers at the time of the study and the method used in their data

collection and interpretation. The assessment by the Agency shown in Figure
3-2 (EPA/OPTS, 1987) was based on a iruch smaller data base than the Agency
currently has and incorporated a less formal system for confirming the data
then is presently being used by the Agency. It is important to note that the
1987 assessment reveals data from states that are not currently in category 5.
This information will most likely be incorporated into category 5 once the
formal data confirmations are complete.
Differences between the current assessment (Figure 3-1) and that of
Parsons and Witt (Figure 3-3) are primarily based on how the data was
collected. Parsons and Witt based their study on a mail-in survey with lead
state agencies. EPA's current assessment has endeavored to obtain data from
additional agencies and sources, differentiate the data based on origin of
contamination, and collect additional background information on the studies
and the analytical technique used to quantify results. The report by Parsons
and Witt has not been formally released at the time of this writing.
U.S. PIRG produced their report in September of 1988 using data from the
public docket. During this time, EPA has acquired additional monitoring
results and confirmations on many of the studies. Some of the data used by
U.S. PIRG has been superceded by updated reports. Some of the detections
credited as being caused by normal agricultural use have been verified as
point-source contamination or the results of nonpesticidal use of chemicals.
The report was generated in a short time frame and as a result, sore chemicals
have been counted twice and are represented by trade names as well as by their
cannon names.
3.4 About the
The appendices include additional information on the data base. Appendix
A outlines the structure and data elements and discusses the confirmation
program. Appendix A also provides guidance on interpreting the tables in the
subsequent appendices.
Appendices B and C can be used to identify the pesticides or states for
each assessment category in Tables 3-1 through 3-6. Details on the detections
3-15
-------
can also be obtained here. Appendix B lists positive detections sorted by
chemical and then by state. Appendix C presents the same data sorted by state
and then by chemical. For each monitoring study reporting detections in
ground water, these appendices present: (a) the suspected or known source of
contamination, (b) the number of wells tested for each pesticide, (c) the
number of positive wells found, (d) the number of samples taten, (e) the
number of positive samples, (f) the range of concentrations of the positives,
(g) the average of all positive concentrations, and (h) the confirmation
rating assigned to the results. To the extent possible, the data in a study
has been itemized by origin of contamination and has been segregated down to
the county level.
Appendix D summarizes all data in the data base by chemical including
studies for which no detections were noted. For each assessment category, the
appendix includes: (a) total number of wells sampled, (b) the total number of
positive wells, (c) the total number of samples taken, (d) the total number of
positive samples, (e) the total number of states in which the chemical was
sampled, (f) the number of states having positive detections, (g) the range of
concentrations of all positive detections, and (h) the range of the average
concentrations of the positives from the individual studies.
It is important to note that this data reflects an automated sort by
computer, and as such certain anctnalies in the parameters may require
explanation. For example, if a particular author has presented his results by
wells and not by samples, the study would not contribute to the sample totals
presented in the appendix. As such, it is conceivable that the tables could
present a larger number of wells than samples. Also, the tables only reflect
totals for studies that are identified as belonging to each respective
assessment category and the statistical population may not be accurately
represented. For example, relating the number of positive wells for a
chemical to the total number of wells sampled can be misleading. Therefore,
each value in the appendix is not conclusive in itself and it is important
that the appendix is used cautiously with this taowledge in mind.
Appendix E contains the bibliography for the studies in the data base.
Comments relative to the studies and/or confirmation process are also included
3-16
-------
here. Appendix F presents the full listing for each study in the data base
and is under separate cover.
It should be noted that each study in the data base is referenced by a
five character identification code (e.g., "OTOOl" for Vermont study 001).
This code can be used to track each study given in Appendices B and c. This
code can be used to obtain the formal reference for the study from Appendix E
and the full data base listing of the study from Appendix F. This code is
also compatible with the filing system used in the public access docket.

4.0 CCNCLUSICNS
4. i Caveats QJQy§ing the Dafcg, Pasg
Agricultural pesticides have been found in domestic drinking water wells
at levels of toxicological concern. Ground-water contamination caused by
pesticides can be the result of many factors including: the physicochemical
characteristics of the pesticide, frequency and rates of application, the
hydrogeologic setting in which the chemical is used, the climatology of its
use environment, and other agronomic practices.
Pinpointing the source of pesticide contamination is perhaps the most
difficult parameter to confirm in the data base. Contamination can result
from causes other than leaching due to normal field applications. These
causes include: pesticide disposal, accidental spills, rinsate from equipment
maintenance, human error in dilution, intentional excess applications, back
siphoning into a well during chemigation, or direct channelling of pesticides
through poorly constructed or damaged wells. It is difficult to conclude with
confidence that an incident of ground-water contamination is attributed to
leaching from normal agricultural use, unless the use histories near the site
are known, and point sources are ruled out.
There are dangers in trying to use the data base to indicate the
statistical significance of the problem on a national level. Mast
significantly is the fact that many agricultural areas have not been sampled
and are not statistically represented in the data. In addition, data
confirmations are not complete and many origins of contamination are unknown.
It is important to note that the studies in the data base have not been
conducted and reported under a single standard protocol. The studies were
designed and conducted by many different agencies for different purposes.
Many of the studies were only designed to sample vulnerable ground water or to
investigate suspected problems, while other studies were designed to be
statistically unbiased. It is important to note that the studies have not
been limited to drinking water supplies and the studies have sampled many
types of wells including wells used only for observation or irrigation. Many
4-1
-------
of the studies have concentrated on shallow ground water which may not be
representative of the drinking water sources of the area. Many of the
detections represent one sampling point in time which cannot measure the
persistence of a problem. As such, the results cannot be used to estimate
human exposure to pesticides in drinking water from a national perspective.
Because the studies were not conducted and reported with the data base in
mind, many of the data base elements have not been reported in the source
documents. Many but not all of these data holes are being resolved through
the data confirmation program. However, assessments made from the data base
can be difficult or inconclusive. Statistics from the data base must be used
carefully and with caution. For example, statistically derived parameters
based on the positives attributed to normal field use are suspect if the
origin of the majority of positives are not known. Similarly, the ratio of
the number of well positives to the number of wells sampled cannot be
determined reasonably if certain references include information on positives,
but none on nondetections. Biases in the design of studies, and where they
have been conducted to date, also influence statistical assessments.
For these reasons, derived parameters cor^iperi ]n the report and in the
-ho i be treated s '''cors rather hai iolute values.
4. 2 Major Data Gaps
There are approximately 130 reports entered in the data base
(representing approximately 150 different monitoring studies). To date, 50
percent of these reports have been confirmed, and roughly 20 percent of all
entries have unknown origins. This accounts for the range in values in
categories 2 and 5. Tto date, nearly 70 percent of the reports incorporated
into the data base by April 1988 have been confirmed.
Difficulties exist in undertaking this kind of a confirmation program.
The Agency is at the mercy of the schedules, cooperation, and ability of each
study director to confirm their results. Some studies cannot be confirmed
because details on the study are not retained in records. Particular states
for which significant data confirmations are pending include: Florida,
4-2
-------
Hawaii, Minnesota, New York, Virginia, and Wisconsin. Ackiitional fiatg gaps
include the following:
• USGS observations wells. USGS routinely monitors for select pesticides
in their ground-water quality monitoring network. These results are
maintained in the Survey's WATSTCRE data base and periodically
transferred to EPA's STCfcET data base. The Survey adheres to a quality
control program on data entered into WATSTCRE. This data has not been
given the highest priority in EPA's Pesticides in Ground Water Data
Base primarily because the origin of contamination for detections are
difficult to assess.
• Aldicarb. The confirmation for many of the aldicarb monitoring
programs has not been completed. Many monitoring studies have been
conducted for aldicarb in ground water from the late 1970's until the
present and the volume of this data is overwhelming. This data
accounts for several of the locations where pesticides have been
detected in Figure 3-2 but not in category 5 of Figure 3-1.
Rhone-Poulenc Ag. company maintains a computerized, data base on ground-
water monitoring results from studies that they have conducted. Their
studies have been limited to drinking water sources and the origin of
positive detections have generally been attributed to nonpoint sources.
We are coordinating Rhone-Poulenc to verify that the Agency's data is
comprehensive and confirmed.
• Atragine. Ciba-Geigy corporation has developed a data base containing
monitoring for atrazine in ground water. Their data base is
attributing roughly 75 and 90 percent of detections of atrazine in
ground water in the United States and Canada,, respectively, to point-
source origins. ciba-Geigy is cooperating with the Agency to resolve
discrepancies between both data bases.
• California. The California Department of Food and Agriculture (CDFA)
has developed an excellent statewide well inventory and data base on
pesticides in ground water. EPA is using this data base as the
principal source for data in California. While their computer data
base has not been fully merged into EPA's data base, the results
presented herein have been obtained from published reports (Brown,
et.al, 1986; Ames, et.al, 1987). Chemical names and information on the
number of positive wells and samples have been obtained from the 1986
report, however, details on the concentrations were not documented in
the report. Confirmed data attributed to agricultural and point source
origins have been obtained from the 1987 report. Since many of the
same wells sampled and reported in the 1987 update had been reported
but not distinguished in the 1986 report, the 1987 data has not been
entered into EPA's data base in order to avoid duplicating wells.
Concentrations and total well counts will be obtained directly from
CDFA's computer data base and incorporated into EPA's data base in the
future.

4.3 Discussion an the Results
Fran the data received to date, the precise representation of pesticide
residues in ground water, as a result of normal agricultural application, is
probably greater than category 5. This is because many of the studies have
yet to be confirmed and many of the unknown sources may have been caused by
normal agricultural practices. In addition, many agricultural areas have not
been sampled. Given the right conditions, nearly every chemical has the
potential to leach to ground water. However, it is iinportant to note that one
or two detections of a pesticide at trace levels may not in and of themselves
indicate a problem. But, a pesticide detected at numerous locations at
concentrations equal to or greater than Health Advisory levels is reason for
concern and further investigation. Therefore, it is critical to look at both
the frequency of detections and their concentrations, and how those
concentrations compare to established and proposed health numbers for a
specific pesticide.
Table 3-5 illustrates that from normal use, 18 pesticides nave been
confirmed in ground water at levels equal to or above established or proposed
Health Advisory levels. It is important to note that all of these pesticides
are on the list of analytes being screened as part of the Agency's National
Pesticide survey.
From Table 3-6, it would appear that an increasing number of pesticides
are contaminating ground water. However, Table 3-6 is better explained by the
fact that more people are looking for pesticides in ground water and these
results reflect increased monitoring efforts. Awareness of the issue has led
to voluntary and mandatory restrictions of many of the more toxic , persistent ,
and mobile chemicals, such as EOT an EBCP. As illustrated in Table 3-5, seven
of the pesticides having detections in excess of Health Advisory levels have
either been cancelled or have had their use severely restricted.
4.4 future Uses of the pgta bv EKV
The data base will be used by the Agency as a tool to supplement the
pesticide registration process. It is currently being used to target
4-4
-------
pesticides that are contaminating ground water inorder to establish priority
candidates for regulation to mitigate such problems. The data base is being
used to help pinpoint the migration pathways and environmental factors
associated with contamination which are the first steps in developing
mitigation strategies. By overlaying pesticide monitoring results with
pesticide use data and hydrogeoglogic factors, it will be possible to
highlight vulnerable areas that are candidates for reduced or altered
application and to depict data gaps where additional monitoring should be
conducted. In addition, the data base can be used in support of the
reregistration of a pesticide for which ground-water contamination has not
been shown to be a problem.
The importance given to the data base to supplement the regulatory
process will increase as the data base evolves. The data base is in a dynamic
state of development; confirmations on the data presently entered in the data
base continue and additional monitoring studies are received periodically.
Many states and pesticide registrants have ongoing ground-^water monitoring
programs and other states and registrants are either implementing or expanding
monitoring efforts. Tnese studies will provide additional information on the
sources and impacts of pesticide residues in ground water. The results and
conclusions contained herein are interim and will be updated as further
information is collected and processed.

APPENDIX A
PESTICIDES IN GROUND WATER DATA BASE
Background
The Pesticides in Ground Water Data Base is a compilation of ground-water
monitoring efforts reported in the literature or obtained through direct
correspondence to the Agency. The data base has been developed by the Ground-
Water Section of the Office of Pesticide Programs, Environmental Fate &
Effects Division, Environmental Fate & Ground-Water Branch (EFED/EFGWB).
Structurally, the data base consists of three data bases: 1)
Bibliographical Data Base, 2) Study Area Data Base, and 3) Pesticide
Monitoring Data Base. The Bibliographical Data Base contains information on
the reference for bookkeeping purposes (e.g. reference identification number,
author, date of publication, date entered into data base, etc.). Often
publications win report the results fron several monitoring studies. To the
extent possible, separate studies or monitoring sites are distinguished in the
Study Area (or Sub-reference) Data Base which contains site and study specific
information on the sampling program (e.g., location, sampling period, etc.).
The Pesticide Monitoring Data Base contains a summary of monitoring results
for each pesticide in each study or sub-reference.
The data base is programmed under Ashton Tate's dBASE III Plus. A sample
listing from the data base is given in Attachment A-l. Elements (data fields)
of each data base are given below:
1. Bibliographical data base

Interpreting Data Base Listings
The following information can aid in interpreting the data in the data base.
• Data base codes are given in Attachment A-2.
• Pesticides are entered by common name pursuant to the Farm Chemicals
(1987) .
• Compounds presented as pesticides in the reference, but not identified
as such in the Farm Chemicals Handbook have been included in the data
base. These compounds are presently being verified.
• Some compounds (e.g. , trichloroethylene) have uses in addition to
agricultural uses, and when known, non-agricultural origins have not
been included.
• Pesticide metabolites have been entered separately if the metabolite
is common to more than one active ingredient and the source pesticide
is not known.
Additional footnotes on the data base are given in Attachment A- 3.
Caveats in Using the Data
All assessments made from the data base must be approached with the
cautions inherent in the nature of the source documents. The monitoring
studies have been conducted by numerous individuals and agencies and have not
been exposed to a regimental protocol or consistent levels of quality control.
Specific notes or limitations of the data base are listed below:
• The reference sources have been subjected to manual screening in
order to reduce data into the data base format.
• The data base does not represent a comprehensive assessment of ground
water contamination by pesticides, nor does it claim to contain a
comprehensive compilation of monitoring efforts. The data base
contains ground-water monitoring results collected to date from
federal and state agencies as well as universities and chemical
manufacturers. The data base is in a developmental state and new
studies are artfled to it daily.
• Many of the references in the data base are incomplete, or rather,
not all elements of EFED/EFGWB's data base are contained in each
reference. For example, a reference may report the number of
positive findings of pesticides in a sampling program without an
indication of the sampling arena (number of wells or number of
samples taken) . Quite often references will cite results by wells
and not by samples or vice versa. Some references do not indicate
the origin or suspected origin of the finding (e.g. , normal use vs.
point source) . Other references do not specify the county in which
the positive was found. Also, there can be overlap between
A-2
-------
references that cannot be distinguished, and therefore, seme data may
be entered twice - erroneously but unknowingly.
• It is important to note that detected positives may not have been
confirmed for all studies contained in the data base. Efforts are
being taken to verify these entries.

EKCA ERSE CODES
• State names are specified according to the two-letter state and
territorial abbreviations issued by the U.S. Postal Service.
• County names are entered by the Federal Information Processing System
(FIPS) codes.
A. code of "B" in the County FIPS code indicates positives are not
broken out by county and further explanation is given in the conment
field of the Monitori-ng study/Location data base. A code of "C"
indicates that the county is explained in the Garments of the
Pesticide Information data base. If the "B" or "C" is preceded by a
number, the number represents the number of counties surveyed.
• Origins of contamination are indicated by the following abbreviations:
- NFU = known normal field use,
- SFTJ = suspected field use,
- PS = known point source,
- SPS = suspected point source,
- DC = known direct channelling to well (e.g., back siphon),
- SDC = suspected direct channelling to well,
- BOTH = suspected normal field use and suspected point source, and
- N/A = origin not identified.
• The type of well is indicated by the following abbreviations:
- DCM = private domestic well,
- PWS = public water supply,
- IRR = irrigation well,
• - LVS = livestock,
- CBS = observation well,
- IND = industrial use well, and
- N/A = type of well not identified.
• Data confirmation is indicated by a code of 1 through 5 in which "1"
is very confident, subsequently "5" is poor quality data. A code of
"0" indicates that the confirmation has not yet been completed for
that entry.
Studies documenting superior quality control programs (e.g., sample
handling, replicate samples, multiple laboratory analyses, analytical
methods, second-column confirmation) are assigned a rating of "1". If
the documentation on one or two points are weak, but otherwise
adequate precautions are taken to ensure the validity of results, a
code of "2" is assigned. Generally, if second column confirmations
were unacceptable, studies were assigned ratings of "3", "4", or "5"
depending on conditions used in obtaining results.
• Entries of "N/A" or "-9" indicate that the information is not known
(for character and numeric fields, respectively).
