I. INTRODUCTION
The U.S. Environmental Protection Agency/Office of Pesticide Programs (EPA/OPP)
is responsible for protecting human and environmental health from unreasonable risk due
to pesticide exposure. Monitoring efforts carried out during the last decade have shown that
the nation's ground water can become contaminated with pesticides, particularly in areas
with high pesticide use and vulnerable aquifers. Therefore, OPP has taken a strong
preventive approach to the protection of this valuable resource. Regulatory activities have
evolved to include, as a condition of registration or re-registration, a more rigorous
evaluation of a pesticide's potential to reach ground water. OPP has also formed strong
partnerships with other federal and state agencies responsible for various aspects of ground-
water protection.
The Pesticides in Ground Water Database (PGWDB) was created to provide a more
complete picture of ground-water monitoring for pesticides in the United States. It is a
collection of ground-water monitoring studies conducted by federal, state and local
governments, the pesticide industry and private institutions. It consists of monitoring data
and auxiliary information in both computerized and hard-copy form. This report, Pesticides
in Ground Water Database -- A Compilation of Monitoring Studies: 1971 -1991, was prepared
to summarize and share the results of the studies in the PGWDB. It consists of 11 volumes;
a National Summary and ten EPA regional summaries. Each volume provides a detailed
description of the computerized PGWDB and a guide to reading and interpreting the data.
The data are presented as maps, graphs and tables.
These data are extremely valuable, but must be interpreted carefully. In general, the
PGWDB provides an overview of the ground-water monitoring efforts for pesticides in the
United States, the pesticides that are being found in the nation's ground water, and the
areas of the country that appear to be vulnerable to pesticide contamination.
When viewed as a whole, it might appear the data gathered for this report are
representative of the United States and/or of general drinking water quality. This is not
necessarily the case. For example, many studies included sampling of aquifers that supply
drinking water, however these samples were usually taken at the well, not at the consumer's
tap. Therefore, conclusions concerning finished water can only be drawn by careful
examination of the data on a study by study basis. In addition, ground-water monitoring
programs vary widely in sampling intensity and design from state to state. Not surprisingly,
the states that sampled the greatest number of wells were often those that found the
greatest number of contaminated wells. This should not be misconstrued to mean that the
ground water in these states is more contaminated than that of other states, or that all
ground water in these states is contaminated. On the contrary, an active, supported
sampling program generally indicates a high regard for ground-water quality.
OV-1

-------
The database and this report are the result of the efforts of a great many individuals,
significant among whom are the state officials and principal investigators who gave
generously of their time to provide OPP with information concerning their work. In
publishing this report, OPP intends not only to provide data, but also to identify points of
contact, in order to share expertise among those responsible for the protection of the
nation's ground-water resources.
To make this information available to as many decision makers in state and other
federal agencies as possible, the computerized portion of the PGWDB will become a part
of the Pesticide Information Network (PIN).1 The PIN is a computerized collection of files
that contain pesticide monitoring and regulatory information. The PIN functions much like
a PC-PC bulletin board and can be accessed by anyone with a computer and a modem. The
PIN is currently undergoing an expansion that will allow new types of information to be
included and increase the number of simultaneous users. The new PIN will be available in
1993 and will contain the PGWDB, environmental fate chemical/physical parameters for
pesticides, pesticide regulatory information (Restricted Use, Special Review, canceled and
suspended) and a certification and training bibliopaphy.
II. THE ROLE OF PESTICIDE MONITORING
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires EPA to
monitor the environment for pesticide residues [section 20, parts (b) and (c)]. The primary
goal of pesticide monitoring is to improve the soundness of FIFRA risk/benefit regulatory
decisions by providing information on the concentrations of pesticide residues and the
effects that exposure to these residues have on human health and the environment In
addition, long-term changes in environmental quality can be detected through the analysis
of monitoring data. OPP can use this information to measure the effectiveness of regulatory
decisions and to indicate potential environmental problems.
EPA has directly sponsored some large-scale pesticide monitoring projects, such as the
National Monitoring Programs of the 1970s2 and the recent National Survey of Pesticides
in Drinking Water Wells? This type of monitoring is intended to provide information on
a national level involving large numbers of pesticides. It does not provide information
concerning localized problems or long-term trends. This method of data gathering is also
extremely resource-intensive. An alternative approach for OPP is to support and gather
information from monitoring studies performed by others. Since the responsibility for
protecting the nation's ground water is shared by federal and state governments, OPP's data-
handling responsibilities not only include procuring the most current information for its own
needs, but also sharing this information with its partners in state and federal agencies. The
development of the Pesticides in Ground Water Database is a step in this direction.
OV-2

-------
III. BACKGROUND
OPP began collecting ground-water studies for the PGWDB in the early 1980s. In 1988,
an effort was made to review and catalog these data. Summary results of this effort were
computerized and then published in the Pesticides in Ground Water Database: 1988 Interim
Report.4
Since the 1988 Interim Report was issued, many things have changed. State-sponsored
projects, initiated in the late 1980s, have been completed and digitized, monitoring
methodologies and computer technology have improved, and the quality and quantity of data
have increased. Based on extensive use of the 1988 database by OPP's Ground Water
Technology Section and the comments received from other users, both within and outside
of OPP, the computerized database and the hard-copy report were restructured. The new
computerized structure is more appropriate for the quality and quantity of the information
currently available, as well as for that expected in the future. The new structure is both well
and sample specific; that is, it contains description and location information for each well
sampled and the results of each analysis. This structure allows ground-water monitoring
data to be sorted in a variety of ways, such as by well depth, well location, and sampling
date. The new report structure provides national, regional, state and county summaries so
that readers can select the resolution appropriate for their needs.
Most of the data in the PGWDB have been produced directly by state agencies or by
private institutions that are sponsored by federal or state agencies. Some pesticide industry-
sponsored studies have also been included in the PGWDB. These studies were conducted
to support the registration status of a particular pesticide and were generally conducted in
areas that are vulnerable to ground-water contamination by pesticides.
The database is a compilation of data submitted in several different formats, including
computerized and hard-copy sampling results as well as hard-copy reports containing study
descriptions and summary information. Many states are now routinely storing their data in
computerized form and have shared their data with OPP. Some of the hard-copy data are
from older studies that were never computerized. Some are from studies that have been
computerized, but OPP has not yet been able to obtain the data. OPP is also retaining
hard-copy final reports for as many studies as possible. These reports provide vital
information such as study design, well design, analytical methods, quality control and
environmental conditions.
The focus of the PGWDB is quite narrow. It contains only ground-water monitoring
data in which pesticides were included as analytes. Therefore, the PGWDB does not
replicate STORET5 or WATSTORE6. While these large databases contain some pesticide
monitoring data and some ground-water data, their primary focus is general water quality.
As a result, these databases contain a great deal more information about water quality, but
lack many of the pesticide focused studies that are included in the PGWDB. Many states
have used STORET to store water-quality data, including analyses for pesticides. STORET
data were downloaded and added to the PGWDB when the data could be directly
OV-3

-------
associated with specific study summaries or reports sent to OPP by state agencies. These
state agencies provided their agency code, station codes, parameter codes, sampling dates
and other pertinent information so that the correct data could be extracted from STORET.
Data from the National Survey of Pesticides in Drinking Water Wells (NPS)3 have not
been included in PGWDB, since these data have been recently and extensively presented
elsewhere. We are currently working on electronically transferring the results of the NPS
pesticide analyses so they will be available when the PGWDB becomes part of the PIN.
IV. THE COMPUTERIZED DATABASE
The computerized database consists of three files related to each other by study
identification and unique well number. The first file contains information describing the
study, the second contains information describing each well and the third contains sample
information. Data elements stored in these files are presented in Figure 1. These data,
elements are based on EPA's recommended minimum set of data elements for ground-water
monitoring published in Definitions for the Minimum Set of Data Elements for Ground-Water
Quality, July 22, 1990?

1.	This is a unique identifier assigned to each well in the well file. Many states have assigned a unique
identifier to wells sampled. In these cases, the number was retained, and used in the PGWDB as that well's
unique well number.
2.	The Federal Information Processing Standard (FTPS) alphabetic or numeric codes for states (example MI
is the alphabetic code for Michigan, 26 in the numeric code for Michigan). County codes are three digit
numeric codes.

3.	Coordinate representations that indicate a location on the surface of the earth using the equator (latitude)
and the Prime Meridian (longitude) as origin. Coordinates are measured in degrees, minutes, and seconds
with an indicator of north or south, and east or west.
4.	Wells have been classified as follow;
Drinking water public community - a system of piped drinking water that either has at least IS service
connections or serves at least 25 permanent residents.
Drinking water public non-community - wells serving public facilities such as fire stations, schools, or
libraries.
Drinking water private - privately owned wells serving a residence or farm.
Non-drinking water monitoring - wells installed specifically for monitoring ground water.
Non-drinking water other - wells used for irrigation, industrial application, etc.
5.	This field will allow storage of limited well log or other information about the well, such as construction
details.
6.	The vertical distance from the National Reference Datum to the land surface or other measuring point in
meters.
7.	Pesticides are tracked by their Chemical Abstracts System (CAS) number. There is also a cross-reference
file that contains all pesticide synonyms and other OFF reference numbers. Any chemical that is currently
or has ever been registered as a pesticide by the USEPA, Office of Pesticide Programs is eligible to be
included in the PGWDB. Some chemicals might be more commonly associated with industrial processes;
however, if these chemicals are now or were previously registered and used as pesticides, monitoring results
will be included in the database.
8.	A short name, reference or description of the analytical method which was used. This field is not intended
to hold the entire method
9.	An origin of contamination is listed for each analysis performed as follows:
NFU - Known or suspected normal field use
PS - Known or suspected point source
UNK - Unknown source of contamination

These files will be available through the PIN in 1993. The data management software
for this system is ORACLE running under UNIX, However, OPP will accept and translate
data created in nearly any format, operating system or medium. To access the PIN, contact

V. THE 1992 PESTICIDES IN GROUND WATER DATABASE REPORT
The 1992 PGWDB report is a summary and presentation of all the data OPP currently
has available, both in computerized and in hard-copy form, concerning pesticides in ground
water. The report is organized as a National Summary and ten EPA regional summaries.
Each volume provides background information on pesticide monitoring, a description of the
computerized portion of the database and a guide to reading and interpreting the data
presented in the report.
OV-5

-------
The National Summary contains summary results of the data collection effort for all
states and a discussion of the data. The regional volumes contain data from the individual
states in each EPA Region. Each regional volume contains state summaries, which consist
of; 1) a short overview of the state's philosophy and pertinent regulations concerning
ground-water quality and pesticides, 2) a summary of each study or monitoring effort sent
to OPP, and 3) summary data for each state presented in tables, graphs and maps. In
essence, the study summaries were written by the principal investigators of each study.
Whenever possible, the author's abstracts, summaries and conclusions were reproduced
verbatim, so that the tone and intent of their work would not be misinterpreted.
There are two appendices in each volume of the report. Appendix I contains a
Pesticide Cross Reference Table, which provides pesticide names, synonyms and the
regulatory status and lifetime Health Advisory (HA) Level or Maximum Contaminant Level
(MCL)7 for each pesticide. Appendix II provides a brief overview and reference information
for the NPS.
Summary and Presentation of Ground-Water Monitoring Data
The data in this report are presented in three different formats: maps, graphs and
tables. Their format and content are explained below. Each format is displayed at four
different resolution levels: national, regional, state and county. The charts and maps were
intended to provide an "at-a-glance" visual summary of the information collected for the area
in question. The tables provide detailed information concerning sampling dates, numbers
of wells sampled, samples analyzed, concentration ranges, and the relationship between
pesticide concentrations and current EPA drinking water standards.
1.	Maps
The maps presented in this report display the number of wells sampled and the number
of wells with pesticide detections. Map legends are consistent throughout the report to
assist in any visual comparison of the maps. A regional-scale map illustrating the
frequency of pesticide detections as a function of the total number of wells sampled is
presented at the beginning of each EPA regional volume. The regional maps display
information for each state in that EPA region. All of the regional maps are included
in the National Summary. In addition, a state- scale map, in which the data are
presented at the county level, is included with each state summary. State maps are also
annotated with a list of pesticides detected in that state.
2.	Graphs
Bar graphs, for each state within a region, illustrate the number of wells sampled, the
number of wells with pesticide detections, and the number of wells with pesticide
detections exceeding the MCL or lifetime HA. The graphs present this information
ranked in descending order by the number of wells with pesticide detections. The
version of this graph in the National Summary displays this information for each state.
 A similar graph in each EPA regional volume presents data only for the states in that
region. The National Summary contains an additional graph, illustrating the above
information by pesticide. Pesticides for which analyses were performed but were not
detected in any wells are listed alphabetically at the end.
OV-6

-------
3. Tables
Two basic data tables are used throughout this report to summarize ground-water
monitoring information: the "Pesticides" table and the "Wells" table. Figures 2 and 3
provide a detailed explanation of the information contained in each column for the two
standard tables. The numbers that occur in the field descriptors correspond to the
definitions listed below the example table.
The "Pesticides" table is illustrated in Figure 2. In this table, information is organized
by pesticide. The monitoring locations, sampling frequencies, number of wells
monitored, sampling results and concentration ranges are provided. In the National
Summary, this table details the monitoring location to the state level and also includes
the regulatory status for each pesticide. In the regional volumes, monitoring location
is provided to the county level for each state and the table is expanded to include
monitoring data for samples taken from each well.

2 The tables are arranged in alphabetical order by the parent pesticide common name, Degradates of parent
pesticides are listed directly following the parent. Any chemical that is currently or has ever been registered as
a pesticide by the USEPA Office of Pesticide Programs is eligible to be included in these tables. Some chemicals
included in these tables are more commonly associated with industrial processes; however, these chemicals were
at some time also registered as pesticides.
OV-7

-------
2 County names are listed in alphabetical order for each pesticide that was monitored.
2 Well sampling dates are given by year and month(s). Months separated by a comma (13) means that samples
were taken in these months only. Months separated by a dash (1-5) is the range of months in which sampling
occurred, samples were taken in all months within the range.
4 The total number of wells that were sampled at least once during the time period stated in the previous
column.
1	Wells with pesticide detections within the time period given in the date column (3). Wells with positive
analytical results were classified based upon whether the results were above or below the MCL, If a pesticide
did not have an established MCL, the lifetime HA level was used and noted at the end of the table. If neither
of these values were established, the well was classified as less than the MCL. Wells were classified based upon
their highest analytical result. Therefore, any well with at least one positive analysis equal to or greater than the
MCL or HA during the time period listed in the date column (3) was classified as > MCL. Any well with at least
one positive analysis but all analyses less than the MCL or HA was classified as < MCL.
6 The total number of samples analyzed for that pesticide within the time period recorded in the date column,
2	Samples with pesticide detections were counted based upon whether the results were above or below the MCL
or lifetime HA as stated in 5 above.
I	The range of positive results in ug/L (ppb) for the time period specified in the date column.
J The total number of discrete wells that were sampled at least once and analyzed for the pesticide listed in
column 1. 'See Note
10	The total number of discrete wells in which the pesticide was detected based upon whether the results were
above or below the MCL. Wells were classified as explained in 5 above, based upon the highest analytical result.
II	Total number of samples analyzed for a particular pesticide.
12	The total number of samples in which the pesticide was detected that are > MCL or < MCL as explained
in 5 above,
13	The grand total of discrete wells sampled in the state for any pesticide. * See Note
14	The grand total of discrete wells with at least one detection of any pesticide. Wells are classified above or
below MCL or HA as explained in 5 above. *See Note
11	Grand total of samples taken in the state. *See Note
M The grand total of samples with any pesticide detection for the state. Samples were classified as > or < the
MCL based upon their highest analytical result as explained in 5 above. *See Note
Note: Some wells were sampled more than once, (i.e., during several successive years) and some wells were
sampled for more than one pesticide. Therefore, the total number of discrete wells is not necessarily the
arithmetic sum of the wells listed. Similarly some samples were analyzed for more than one pesticide, therefore,
the total number of discrete samples for the state will not be, in all cases, the arithmetic sum for the column.

Figure 3 illustrates the "Wells" table. In this table, ground-water monitoring information
is organized by well type, or use, and source of contamination. In the National
Summary, the information is summarized by state. In the regional volumes, the
information is summarized by county for each state in the region.

3	Other wells include: irrigation wells, stock watering wells, springs, and tile drains.
4	Total number of each type of well sampled in each county.
1	The number of wells per county in which a pesticide was detected. Wells were classified based upon whether
the results were above or below an MCL for any of the pesticides detected. If a pesticide did not have an
established MCL, the lifetime HA level was used. If neither of these values were applicable, the well was
classified as less than the MCL and it was so noted at the end of the table. Wells were classified based upon
their highest analytical result. Therefore, any well with at least one positive analysis greater than or equal to the
MCL or HA was classified as > MCL. Any well with at least one positive analysis but all analyses less than the
MCL or HA was classified as < MCL,
Contaminated wells were placed in one of the following categories based on the opinion of the study director;
6 NFU = Known or Suspected Normal Field Use.
2	PS = Known or Suspected Point Source.
1 UNK=Unknown source of contamination. Wells were categorized as "unknown" if the study director did not
know the source of contamination, or if there was no information available concerning the source of
contamination.
9 Total number of wells in each category.

VI. DATA INTERPRETATION
Ground-water monitoring data in this report have been assembled from numerous
sources, including state and federal agencies, chemical companies, consulting firms, and
private institutions that are investigating the potential for ground-water contamination by
pesticides. These data are extremely valuable, but must be interpreted carefully. In general,
the PGWDB provides a relatively comprehensive overview of the ground-water monitoring
efforts for pesticides in the United States, the pesticides that are beiiigjfound in the nation's
ground water, and the areas of the country that appear to be the most vulnerable to
pesticide contamination.
Nationally, part of OPP's regulatory mission is to prevent contamination of ground-
water resources resulting from the normal use of registered pesticides. OPP routinely
reassesses the impact that registered pesticides have on the quality of ground-water
resources. The PGWDB will be used to support ongoing regulatory activities, such as
ground-water label advisories, monitoring studies required for pesticide re-registration and
special review activities. In addition, combining the information in the PGWDB with other
environmental fate data and usage data will assist OPP, at an early stage in the regulatory
process, in refining criteria used to identify pesticides that tend to leach to ground water.
On a state or local level, the PGWDB can be used as a reference so that a state may
access data from neighboring states. Evidence that pesticide residues occur in ground water
can be used to target a state's resources for future monitoring and to re-assess pesticide
management practices to prevent future degradation of ground-water quality. The
information presented in this report will also be useful to state and regional agencies when
implementing two pollution-prevention measures being developed by EPA; the Restricted
Use Rule and the State Management Plans outlined in the Pesticides and Ground Water
Strategy. Additional uses for the data in the PGWDB include identification of areas in need
of further study, identification of the intensity of monitoring for particular pesticides, and
graphic display of ground-water monitoring activities and localization of pesticide
contamination.
VII. DATA LIMITATIONS
Despite their apparent value, these data do have limitations and must be used and
interpreted carefully. Differences in study design, laboratory procedures/equipment,
sampling practices, or well use can affect results. Some of the limitations governing the
interpretation of the data in the PGWDB are discussed below:
1) The PGWDB is not a complete data set of all ground-water monitoring for
pesticides in the United States. While we have attempted to include as many
sources as possible, other data exist of which we are not aware or to which we do
not yet have access.
OV-IO

-------
2)	Monitoring for pesticides in ground water has not been performed in a uniform
manner throughout the United States. Some states have extensive monitoring
programs for pesticide residues, while others have more limited monitoring
programs. In general, more extensive pound-water monitoring programs tend to
be found in the states where pesticide use is heavy. This creates a picture that does
not necessarily represent the overall impact of pesticides on ground-water quality
nationwide.
3)	Differences in ground-water monitoring study design can radically affect the results.
Many monitoring efforts were initiated in response to suspected problems, and
therefore yielded a disproportionately high number of positive samples. These
results cannot be extrapolated to represent a larger region or state. Other efforts
sampled a small number of wells or sampled under conditions in which
contamination was unlikely. Still others were statistically designed studies, intended
to be extrapolated to a specific population of wells. Each of these scenarios
presents a vastly different view of the condition of the ground-water resource
sampled.
4)	Analytical methods and limits of detection have changed over time, and also vary
from laboratory to laboratory. Therefore, comparisons between the results of
different studies and across several years must be performed carefully to avoid
errors in interpretation.
5)	Differences in construction, depth, location and intended use can greatly affect the
likelihood that a particular well will become contaminated by pesticides. Some of
these issues were addressed in the individual study summaries when such details
were available. However, this information was not always provided and tends to
be obscured when large amounts of data are summarized. Tlie reader is cautioned
to read the study summaries carefully and interpret the resulting data summaries
conservatively.
VIIL the FUTURE
The vulnerability of ground water to contamination by pesticides depends upon a variety
of factors including depth, topography, soil, climate, pesticide use and pesticide application
practices. In some cases, ground water is shallow or closely connected with surface water
and the results of surface activities can be observed within months. More often,
contamination is not observed for many years, allowing cause-and-effect relationships to
become obscured. This report, for the most part, is a retrospective examination of the
agricultural practices of the 1960s and 1970s, the results of which were observed through
monitoring performed 20 years later. The condition of our ground-water resources for the
next 20 years will be greatly affected by how we are handling our chemicals now. Our
challenge today is clearly prospective.

-------
EPA's Office of Pesticide Programs (OPP) is planning to publish a summary report of
the data in the PGWDB on approximately a yearly basis. We are interested in presenting
the data in a manner that is the most helpful to as many users as possible. The following
are areas in which we would like to receive comments:
1.	Should future reports summarize only "new data" (those received since the last
report) or all of the data? Should we continue to report very old monitoring data
(10 to 20 years), given the fact that some of these studies had very high detection
limits and monitored for pesticides that are no longer of regulatory interest?
2.	What changes should be made to the maps, graphs and tables? Are they too
detailed or not detailed enough? Are important pieces of information missing? Is
there a clearer or more useful way to present these data?
3.	How are those outside of OPP using the PGWDB?
We appreciate all of those who took the time to comment on the draft version of this
report. Many of the suggestions offered were included in this final version. However, some
very good suggestions regarding changes to the tables could not be included in this report
due to time constraints. These suggestions were taken seriously and will be considered for
future reports.
For the PGWDB to retain its value, OPP must continue to gather and share as much
pesticide monitoring information as possible. Any government agency or private institution
that would like to have its work included in the PGWDB should provide a hard copy of a
final or interim report and the sample and well data in electronic format. PGWDB data
elements are listed on page OV-4 of this report. Electronic media should be accompanied
by a description that includes, hardware compatibility (IBM, Apple etc.), operating system
(DOS, UNIX, OS2), format identification (ASCII or software package name) and a data
dictionary. Anyone wishing to provide comments or data may do so by contacting:

OVERVIEW OF STATE LEGISLATIVE AND ENVIRONMENTAL POLICIES
REGARDING PESTICIDES IN GROUND WATER
Under Arizona's Revised Statutes for Water Quality Control, effective January 1, 1991, a
ground-water protection list of pesticides with the potential to pollute ground water was
established. Use of any pesticides included on the list must be reported to the Director of
the Arizona Department of Environmental Quality. The statutes also specify soil and
ground-water monitoring requirements in areas of the state where pesticides are primarily
used, or where other factors indicate a probability of pesticides migrating into ground water.
The aim of the monitoring program is to more accurately determine the mobility and
persistence of the pesticides, and to determine if pesticides have migrated into ground water.
The hydrology section of the Department of Environmental Quality tracks all pound-water
samples in the state and has established a state ground-water sampling database. Ground-
water quality is also monitored by the Arizona Department of Water Resources under a 10-
year management plan.
REPORTED STUDIES OF PESTICIDES IN GROUND WATER
Ellington, Stephen B. and Melanie B. Redding (March 1988), Random Survey of VOC's,
Pesticides, and Inorganics in Arizona's Drinking Water Wells, Arizona Department of
Environmental Quality, Phoenix, Arizona. Study conducted between July 1986 and January
1987. (Reported in the proceeding of FOCUS Conference on Southwestern Ground Water,
March 23-25, 1988, Albuquerque, New Mexico, pp. 223-247). For further information
contact: Pesticide Unit, Water Quality Assessment Section, Arizona Dept. of Environmental
Quality, Phoenix, AZ 85012. Tel.: (602) 207-4552.
Primary Objective
A random survey of public water supply wells was conducted to: (1) describe baseline water
quality for inorganic and organic compounds in wells and monitor 30 unregulated chemicals
with Action Levels; (2) statistically project the water quality of Arizona's drinking water
wells; and (3) provide a quality assurance audit for the anticipated Arizona regulatory self-
monitoring program. Data from the study were expected to be useful in regulating
previously unmonitored volatile organic chemicals (VOCs) and pesticides as required by the
amended Safe Drinking Water Act (SDWA).

Design	1
Between July and September, 1986, 40 public water supply (PWS) wells were tested.
Resampling was conducted in January 1987 to confirm any positive detections. One well
was selected from each of 36 randomly selected PWSs; two wells each were included from
the White Tanks System in Maricopa County and the Casa Grande System in Pinal County.
Thirty-six of the wells selected for the study were located in the Basin and Range Province,
one well was located in the Plateau Uplands and 3 wells were located in the transitional
Central Highlands. Wells were distributed in the following counties: Coconino (1 well);
Cochise (4 wells); Greenlee (1 well); La Paz (1 well); Maricopa (10 wells); Mohave (3
wells); Navajo (1 well); Pima (4 wells); Pinal (9 wells); Santa Cruz (2 wells); Yavapai (2
wells); and Yuma (2 wells).
Well samples were analyzed for the following pesticides: acrolein, aldicarb, l,2-dibromo-3-
chloropropane (DBCP), and ethylene dibromide (EDB). The pesticides DBCP and EDB
were determined using a GC method with liquid/liquid extraction, and aldicarb was
determined using an unspecified Union Carbide method. Additional regulated inorganic
and organic parameters were analyzed by unspecified methods. The implied detection limits
were 8,43 ppb for acrolein, 0.2 ppb for aldicarb, 0.02 ppb for EDB, and unreported for
DBCP. If a result for an organic parameter equalled or exceeded the method detection
limit, the well was resampled and a second analysis completed. Results were assured by
carrying VOC/pesticide travel blanks (one per cooler), and completing replicate (n=5), split
(n=2), and spiked analysis (n=2). Concentrations measured in the VOC/pesticide travel
blanks were subtracted from the sample results. Statistical manipulations were completed
with the Statistical Analysis System (SAS).
Results and Conclusions
Of the 40 PWS wells, only one well, located in the city of Peoria in Maricopa County,
contained positive pesticide results. DBCP residues of 0.0085 and 0.019 ppb were detected
in the original sample collected 7/30/86 and in resampling on 1/7/87, respectively. These
levels do not exceed the maximum contaminant level (MCL) of 0.2 ppb for DBCP. The
Peoria well was surrounded by citrus groves where DBCP was widely used as a nematocide.
Unresolved fluctuations in EDB concentrations occurred in one well located in the town of
Mesa (Maricopa County). Analysis of split samples collected January 1987 produced one
positive detection at 1.040 ppb at Mesa, and one nondetectable result at the State
Laboratory Service as a result of interfering peaks. A subsequent sample (April 1987)
yielded nondetectable EDB residues (< 0.02 ppb).
Volatile organic compounds were detected in four wells and pesticides in one. None of
these results exceeded the state Action Levels. When this magnitude of occurrence in
projected, 121 community systems are estimated to contain detectable levels of VOC's
and/or pesticides.

REGARDING PESTICIDES IN GROUND WATER
The California Department of Food and Agriculture (CDFA) has responsibility for
regulation the sales and use of pesticides in California. This responsibility includes providing
for the proper, safe and efficient use of pesticides for protection of the public health and
safety and protecting the environment from harmful pesticides. To achieve the specific goal
of ground water protection, the CDFA actions have focused on 1) identifying pesticides that
present a threat to ground water quality as a result of agricultural use and 2) talcing
appropriate regulatory action to prevent or mitigate ground water contamination.
The Pesticide Contamination Prevention Act (PCPA), Assembly Bill 2021 became effective
January 1 1986. Section 13152, subdivision (c) requires that the CDFA maintain a statewide
data base of wells sampled for pesticide active ingredients and that agencies that sample
wells for pesticides submit their sampling results to the CDFA, Subdivision (e) requires the
CDFA, in consultation with the California Department of Health Services (CDHS) and the
State Water Resources Control Board (SWRCB), to annually report the database
information.
In January 1989 regulations were adopted in Titles 3 and 36 of the California Code of
Regulations pertaining to ground water protection. These regulations do the following:
Establish values used to identify pesticide with the potential to pollute ground water,
-	Establish the Ground Water Protection List which identifies pesticide that have
polluted or have the potential to pollute ground water and implement the sales and
use reporting requirement for pesticides on this list,
Establish a new category of restricted material that contains pesticide that have been
found in ground water,
-	Define a Pesticide Management Zone (PMZ) as a geographical are of approximately
one square mile which is sensitive to ground water pollution,
Establish ground water protection restrictions which require a permit for use of a
leaching pesticide in a PMZ.
-	Establish use requirements that prohibit all agrichemical, outdoor institutional and
outdoor industrial uses of atrazine in its PMZs.

REPORTED STUDIES ON PESTICIDES IN GROUND WATER
Since the State of California collects, computerized and reports on all of its ground water
monitoring, this report will use only this source as a reference for California, CDFA has
been extremely cooperative in providing OPP/USEPA with computerized raw data and
finished reports.
Cardozo, C, C. Moore, M. Pepple, J. Toriano, D. Weaver; Sampling for Pesticide Residues
in California Well Water: Well Inventory Data Base 1986-1990, Environmental Hazards
- Assessment Program, California Department of Food and Agriculture, State Water Quality
Control Board
Primary Objective
The CDFA began developing the well inventory data base in late 1983. The purposed of
the data base were to help the CDFA in: 1) centralizing reliable information on the
occurrence of non-point source contamination of ground water by the agricultural use of
pesticides; and 2) numerically, graphically and spatially analyzing the data. Prior the PCPA,
only agricultural non-point source data were included. The scope of the data base has since
expanded and now includes whatever pesticide-related well sampling results are submitted
to the CDFA.
Design
The PCPA requires all agencies that sample wells for pesticides to submit their sampling
data and analytical results to the CDFA for inclusion in the well inventory data base. The
CDFA, SWRCB and CDHS jointly agree on a set of minimum well sampling requirements
for all results submitted to the CDFA. These include:
1.	State well number	7. sampling agency
2.	county	8, analyzing laboratory
3.	date of sample	9. street name and number of well location
4.	chemical analyzed	10. well type
5.	individual sample	11. sample type
concentration (ug/L)
6.	minimum detection limit (ug/L)
Optional information to be included when available:
1.	method of analysis	5. year drilled
2.	well depth (ft)	6. location of drillers log
3.	screen depth and length	7. source of contamination
4.	depth of standing water

HAWAII
OVERVIEW OF STATE LEGISLATIVE AND ENVIRONMENTAL POLICIES
REGARDING PESTICIDES IN GROUND WATER
Ground water sampling in the state of Hawaii began in 1979 in response to the
discovery of l,2-dibromo-3-chloropropane (DBCP) in California ground waters and a
request from the US Environmental Protection Agency to monitor for the presence of
this chemical in ground water of other use areas. Since that time Hawaii's program has
expanded to include other fumigants, herbicides and industrial chemicals.
REPORTED STUDIES ON PESTICIDES IN GROUND WATER
1) Hawaii Department of Health,
Ground Water Protection Program (808-548-4362)
Drinking Water Protection Program (808-548-2235)
Giambelluca, Thomas W, University of Hawaii at Manoa;
Hawaii Ground Water Contamination Database
Primary Objective
Over the past several decades soil fumigants have been extensively used in the
pineapple industry to control nematodes. Hundreds of meters of soil and rock between.
the ground surface and the basal waters of the State's aquifers were originally considered
sufficient to prevent leaching of detectable amounts of pesticide residues to ground
water. When other states that used fumigants began finding residues of these pesticides
in their ground water, Hawaii became concerned that the Pearl Harbor basaltic aquifer
might also be vulnerable to contamination and a monitoring program was begun. This
aquifer is the primary source of potable water for Honolulu and the State's most
important ground water resource. Results of ground water sampling in Hawaii have
been computerized in the Hawaii Ground Water Contamination Database.

Design
Samples were taken from public and private drinking water wells on the islands of
Kauai, Oahu, Molokai, Lanai, Maui, and Hawaii. Sampling areas targeted pineapple
plantations where fumigants were used heavily to control nematodes. Samples were
analyzed by various laboratories including the Hawaii Department of Health, US
Geological Survey, US Environmental Protection Agency, Hawaii Sugar Planters
Association, University of Hawaii, Del Monte Corporation and several contract
laboratories. Efforts were made to confirm positive samples.
Results
Analyses of early samples (1979) for DBCP and EDB were all negative. However, as
instrumentation improved, and sampling frequency and area increased these and other
chemicals were detected in Hawaii's ground water. Detectable levels of DBCP, EDB
and TCP have been found in wells located within the Pearl Harbor aquifer. From 1982
to 1983, 10 potable water wells located in central Oahu were closed due to DBCP or
EDB contamination.

0 Unsupported: The produeer(s) of the pesticide has not made or honored a
commitment to seek reregistration, conduct the necessary studies, or pay
the requisite fees for reregistration of the product.
C Canceled: The active ingredient is no longer contained in any registered
pesticide products.
R Restricted Use: The pesticide has been classified as a Restricted Use
Pesticide under 40 CFR Part 1, Subpart 1. it is therefore restricted to
use by a certified applicator, or by or under the direct supervision of a
certified applicator.

Pesticides in Ground Water Database - 1992 Report
APPENDIX II - NATIONAL SURVEY OF PESTICIDES IN DRINKING
WATER WELLS

-------
NATIONAL SURVEY OF PESTICIDES IN DRINKING WATER WELLS
At this time the Pesticides in Ground Water Database does not contain data from
the National Survey of Pesticides in Drinking Water Wells (NPS). These data have been
recently analyzed and published.3 OPP is currently working on importing the results of
the pesticide analyses, so that they will be available when the PGWDB becomes part of
the Pesticide Information Network, The following is a short description of the NPS and
a summary of findings from the NPS.
The NPS is a joint project of EPA's Office of Drinking Water and Office of
Pesticide Programs. This survey is the first national study of pesticides, pesticide
degradates and nitrate in drinking water wells. The Survey has two principal objectives:
1) to determine the frequency and concentration of pesticides and nitrate in drinking
water wells nationally; 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 ground water to contamination. The focus of the Survey was on
the quality of drinking water in wells, rather than on the quality of ground water, surface
water or drinking water at the tap. The Survey was designed to yield valuable
information on both the frequency and levels of pesticides, pesticide degradates and
nitrate in rural domestic (private) and community (public) drinking water wells on a
nationwide basis. The Survey was not designed to provide an assessment of pesticide
contamination in drinking water wells at the local, county or State level.
More than 1300 wells were sampled, some in each State, for 127 analytes. Nitrate
was the most commonly detected analyte in these wells. Based upon the NPS results
EPA estimates that nitrate is present at or above the analytical minimum reporting limit
of 0.15ug/L in about 52.1% or community wells, and 57% of rural wells nationwide.
The survey detected pesticides and pesticide degradates much less frequently than
nitrate. Twelve of the 126 pesticides and degradates were found in the sampled wells.
EPA estimates that 10.4% of community wells and 4.2% of rural domestic wells in the
United States contain pesticides or pesticide degradates at or above the analytical
minimum reporting limit. The two most commonly found pesticides were DCPA acid
metabolites (degradate of dimethyl tetrachloroterphthalate) and atrazine. The following
is a list of the pesticides found in each type of well in alphabetical order.
Community:	atrazine, DCPA acid metabolites, dibromochloropropane,
dinoseb, hexachlorobenzene, prometon, simazine.
Rural Domestic: alaehlor, atrazine, bentazon, DCPA acid metabolites,
dibromochloropropane, ethylene dibromide, ethylene thiourea,
gamma-BHC (lindane), prometon, simazine.
