 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
                                       1-3

 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).

 2.1  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

sampled, number of  positive wells found, and the ranges of concentrations)  for

 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:

             united States Environmental Protection agency
             Office of Pesticides Program
             Field Operations Division (TS-787C)
             Public Docket & Freedom of Information Section
             401 M Street, S.W.
             Washington, DC  20460
             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
                                   3-7

 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

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. i  Caveats QJQying 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.

     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.

                     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:

 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.

   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).
