Ground-Water Quality in Kings, Queens, and Western 

Nassau Counties, Long Island, New York, 1992-96, with 

Geophysical Logs from Selected Wells

By Richard A. Cartwright, Anthony Chu, Jennifer L. Candela, Valerie-ann K. Eagen, 

Jack Monti, Jr., and Christopher E. Schubert

Abstract

This report presents 1992-96 water-quality 

data from 116 wells, and geophysical well logs of 

11 wells, in Kings, Queens, and western Nassau 

Counties, N.Y. It also (1) summarizes the hydrogeologic framework of Kings and Queens Counties, (2) describes the monitoring-well network, 

including 37 wells that were added to the U.S. 

Geological Survey data base during 1992-95, and 

(3) summarizes the methods of data collection, 

analysis, and quality control.

A total of 29 new wells were installed in 

Kings and Queens Counties from November 

1992 through October 1995. Of the 29 wells, 4 

are screened in the Lloyd aquifer, 3 are screened 

in the Magothy aquifer, 4 are screened in the 

Jameco aquifer, and 18 are screened in the upper 

glacial aquifer.

Ground-water sampling and analyses were 

done during three periods August 1992 through 

January 1993, July through September 1995, and 

March through July 1996. The U.S. Geological 

Survey National Water Quality Laboratory performed the analyses for organic and inorganic 

compounds and nutrients for the first two periods 

and the analysis for inorganic compounds and 

nutrients in the third period. Veritech Laboratories, 

of Butler, N.J., performed the analyses for organic 

compounds during the third period. (Results of the 

organic compound analyses are available from the 

New York City Department of Environmental Protection.) Results of U.S. Geological Survey analyses from all three sampling periods are presented 

here in two tables inorganic compounds, including nutrients, and organic compounds.

Borehole-geophysical logs were obtained 

from 11 of the 29 new wells. Borehole-logging 

techniques used in this study included natural 

gamma (G), spontaneous potential (SP), singlepoint resistance (SPR), normal resistivity (R), and 

electromagnetic induction (EM). Wells were 

logged with at least one, and as many as five, of 

these techniques.

INTRODUCTION

Kings and Queens Counties, on western Long 

Island, N.Y. (fig. 1), obtain nearly all drinking water 

(about 700 Mgal/d; Buxton and others, in press) from 

an extensive upstate reservoir-and-water-tunnel system 

owned and operated by the New York City Department 

of Environmental Protection (NYCDEP), which provides water to the City's five boroughs and to several 

upstate counties. A small amount (about 20 Mgal/d) of 

ground water is pumped for public supply in Queens 

County. Emergency supplies are obtained from the 

Hudson River when the city's system is unable to meet 

water demands during some periods of drought. Concern that the present system will be inadequate during 

future droughts or other emergencies has prompted 

consideration of using ground water from Kings and 

Queens Counties as a supplemental source.

The aquifer system underlying Kings and Queens 

Counties served as the sole source of water supply for 

the two counties until 1917, when the first water tunnel 

from the upstate reservoir system to Kings and Queens 

Counties was built. Ground-water pumping continued 

to increase as the island's population increased, and, by 

the 1940's, overpumping had caused extreme watertable declines and saltwater encroachment, which 

necessitated the shutdown of many supply wells. Overpumping also caused the downward migration of surIntroduction

face contaminants, such as nitrate from cesspools, and 

chloride from road salt, from the shallow aquifer to 

deeper aquifers in several areas. All pumping for public supply was stopped in Kings County by 1947 and in 

western Queens by 1974 as a result of deteriorating 

water quality (mostly from saltwater encroachment). 

As a result, increasing amounts of water from the 

upstate reservoirs were needed. In March 1997, the 

reservoir system supplied about 328 Mgal/d to Kings 

County and about 132 Mgal/d to Queens County (Odd 

Larson, New York City Department of Environmental 

Protection, oral commun., 1997). The cessation of 

most public-supply pumping has allowed water levels 

to recover, but this has resulted in the flooding of 

underground structures in some areas. The most severe 

cases (basement and subway-tunnel flooding) are in

parts of Greenpoint, Williamsburg, South Brooklyn, 

and East New York in Kings County (fig. 1), and in 

Maspeth, Ozone Park, Howard Beach, South Jamaica, 

Springfield Gardens, Laurelton, and Rosedale in 

Queens County (O'Brien and Gere, 1986). Continuous 

dewatering is needed to protect these underground 

structures; the estimated pumping rate in 1986 was 

about 18 Mgal/d (O'Brien and Gere, 1986).

In April 1992, the U.S Geological Survey 

(USGS), in cooperation with the NYCDEP and their 

consultant, Malcolm Pirnie, Inc., began a 4-year 

project as a followup to previous USGS studies 

(Buxton and Shernoff, 1995 and Buxton and others, in 

press) to evaluate the feasibility of using ground water 

in Kings and Queens Counties as a supplement to the 

upstate reservoir supply during droughts. The consult2 Ground-Water Quality in Kings, Queens, and Western Nassau Counties, Long Island, New York, 1992-96, with Geophysical Logs
ant's responsibilities included engineering investigations, facility plans, and environmental assessments 

for the study. The USGS responsibilities included 

hydrologic investigations specifically, a data-collection and monitoring component, and development of a 

ground-water-flow model.

The data-collection and monitoring component 

entailed (1) compilation of past and present water levels, water-quality data, and streamflow data; and (2) 

installation, sampling, and geophysical logging of new 

monitoring wells. All water samples were analyzed for 

186 chemical constituents and physical characteristics-, 

including selected suites of inorganic and organic 

compounds. Results of the inorganic-compound and 

nutrient analyses are presented in table 3; results of the 

organic-compound analyses are presented in table 4 

(both at the eid of report).

The modeling component of the USGS study 

entailed construction of a three-dimensional groundwater-flow model of western Long Island to simulate 

the effects of several pumping scenarios on groundwater levels and flow patterns (Misut and Monti, in 

press). A two-dimensional, cross-sectional model was 

used to validate the assumption of stationary lateral 

zero-flow boundaries of freshwater-saltwater interfaces (Kontis, in press). The results will be useful in 

the selection of optimal locations and withdrawal rates 

for new water-supply wells that will cause minimal 

saltwater encroachment and contaminant migration. 

Other considerations during the site-selection process 

are (1) proximity to active and inactive well fields, (2) 

proximity to present distribution mains, (3) availability of City-owned property, and (4) the proposed wellfield area's susceptibility to flooding.

Approach

The network of 106 observation and industrialsupply wells fror1 which ground water was sampled 

during the 1980's (Buxton and Shernoff, 1995) was 

inspected to identify wells from which samples could 

still be obtained. Wells from the USGS monitoring network were substituted for those that could no longer be 

sampled. Locations from which additional hydrologic 

information was needed were then selected, and new 

wells were installed at these locations. A total of 37 

wells were added to the USGS data base 29 were 

installed for this project, and 8 had been installed earlier by Brooklyn Union Gas Co. (BUG), New York

City Department of Sanitation (NYCDS), or 

NYCDEP. Ground-water sampling and chemical analyses were done during three periods: th" initial period 

(1992-93) entailed sampling 87 of the original 106 

wells, the second period (1995) entailed sampling 

21 of the 29 new wells, and the third period (1996) 

entailed sampling 101 wells f'om the first two sampling periods. Geophysical logs were obtained from 

11 of the new wells, as described in the "Geophysical 

Logging" section, further on. Some western Nassau 

County wells were included in the sampling because 

ground water flows from parts of western Nassau 

County into eastern Queens County and, thus, affects 

the water quality and flow patterns in the study area.

Purpose and Scope

This report is one in a series resulting from the 

cooperative project with the NYCDEP. This report 

presents water-quality data from 116 wells in Kings, 

Queens, and western Nassau Counties and the geophysical logs of 11 wells in Kings and Queens Counties; it also (1) summarizes the hydrogeologic 

framework of Kings and Queens Counties, (2) 

describes the monitoring-well network, and (3) summarizes the methods of data collection, chemical analysis, and quality control. All water-quality data were 

collected during the three sampling periods from 

August 1992 through July 1996.

Location and Setting

The study area (Kings, Queens, and western Nassau Counties, fig. 1) encompasses an area of about 

264 mi2 ; Kings County occupies about 76 mi2, 

Queens County about 113 mi , and the western Nassau 

County area 75 mi2. The study area is bounded on 

three sides by saltwater to the west by The Narrows, 

New York Bay, and the East River, to the north by the 

East River and Long Island Sound, and to the south by 

Jamaica Bay and the Atlantic Ocean. The eastern 

boundary is within western Nassau County.

Previous Studies

Many hydrogeologic investigations have been 

done on Long Island during the last century. Previous 

studies most used for background information during

Introduction 3
this investigation are mentioned here. Some of the earliest studies (Veatch and others, 1906; Fuller, 1914; 

and Suter and others 1949) addressed the geology and 

ground-water resources of the entire Island. Subsequent studies investigated problems resulting from 

human activities. Lusczynski (1952), Perlmutter and 

Soren (1962), Soren (1976), Buxton and others 

(1981), O'Brien and Gere (1986), and Buxton and 

Shernoff (1995) addressed water-table fluctuations 

resulting from pumping in Kings and Queens Counties. Lusczynski (1966), Soren (1971), Kimmel 

(1972), Buxton and others (1981), Buxton and Shernoff (1995), and Chu and Stumm (1995) addressed 

ground-water contamination in Kings and Queens 

Counties by nitrate and (or) chloride. Most recently, 

Buxton and others (in press) constructed a groundwater-flow model for Kings, Queens, and Nassau 

Counties to investigate the feasibility of using ground 

water for public supply.

HYDROGEOLOG1C FRAMEWORK

The water-bearing units of western Long Island 

consist of a wedge-shaped accumulation of unconsolidated sediments that range in age from Pleistocene to 

Upper Cretaceous and lie unconformably on crystalline bedrock (table 1). Bedrock crops out in northwestern Queens County and dips southeastward at 

about 80 ft/mi; the several overlying units also dip and 

thicken southeastward. These units consist of clay, silt, 

sand, gravel, and boulders. Together they attain a maximum thickness of more than 1,110 ft in southeastern 

Queens, and of about 800 ft in southeastern Kings 

County. The northwestern limits of these units differ, 

depending on the altitude of sea level at the time of 

deposition, the depositional environment, and on the 

degree of post-depositional erosion. The Cretaceous 

deposits are severely eroded in at least one northsouth-trending channel in Queens County; this channel is speculated to be an ancestral channel of the Hudson River (Soren, 1978, pi. 2) and is filled with 

Pleistocene deposits. Detailed discussions of the 

stratigraphy of Kings and Queens County can be 

found in Veach and others (1906), Fuller (1914), 

de Laguna (1948), and Suter and others (1949). Much 

of the information presented below is derived from 

Soren (1978), and Buxton and Shernoff (1995).

Pleistocene Deposits

The Pleistocene deposits comprise three hydrogeologic units upper glacial aquifer, Gardiners Clay, 

and Jameco aquifer. Each of these units are present in 

Kings and Queens Counties.

Upper Glacial Aquifer

The upper glacial aquifer lies at the surface 

throughout most of Kings and Queens Counties and 

ranges from 0 to 300 ft in thickness. It consists mainly 

of Wisconsin-aged sediments that include (1) glacial 

moraine deposits of clay, silt, sand, gravel, and boulders, and (2) outwash deposits of sand and gravel. The 

upper glacial aquifer unconformably overlies the Cretaceous units. Horizontal hydraulic conductivity is high 

but variable 270 ft/d in outwash deposits (Franke and 

Cohen, 1972), and probably half that in poorly sorted 

moraine deposits (Buxton and Shernoff, 1995).

Gardiners Clay

The Gardiners Clay is present throughout most of 

Kings and southern Queens County and ranges from 0 

to more than 100 ft in thickness. It consists of greenish-gray clay and silt, and some interbedded sand, and 

was probably deposited in lagoonal and marine environments during an interglacial period (Soren, 1978).

The Gardiners Clay has a vertical hydraulic conductivity of about 0.001 ft/d (Franke and Cohen, 1972) and 

restricts vertical flow between the upper glacial aquifer 

and the underlying Jameco and Magothy aquifers.

Jameco Aquifer

The Jameco aquifer is present in most of Kings 

and southern Queens County and ranges from 0 to

more than 200 ft in thickness. This unit is of fluvial origin and is thickest in ancient buried valleys. It is considered to be a channel-fill deposit associated with the 

ancestral Hudson River. The Jameco gravel consists 

primarily of coarse sand and gravel with small 

amounts of silt and clay; boulders are also present. It 

has a horizontal hydraulic conductivity greater than 

270 ft/d (Soren, 1971) and is a productive aquifer. It is 

confined by the Gardiners Clay (where present) and

Hydrogeologic Framework
unconformably overlies the Magothy aquifer. 

Although the Jameco aquifer and the underlying Magothy aquifer are separate hydrogeologic units, they can 

be considered as a single aquifer (Jameco and Magothy 

aquifer) because they are hydraulically connected.

Upper Cretaceous Deposits

Upper Cretaceous sediments make up the bulk of 

the deposits on Long Island. They are divided into the 

Magothy aquifer, the Raritan confining unit (hereinafter called the Raritan clay), and the Lloyd aquifer, as 

described below.

Magothy Aquifer

The Magothy aquifer is present in the southern 

part of Kings and Queens Counties and ranges from 

0 to 500 ft in thickness. A prominent feature of this 

unit in Queens County is the deep, north-south channel 

(ancestral Hudson River system) that was eroded 

through the aquifer and penetrates the underlying 

units. The channel is filled with Pleistocene deposits. 

Similar smaller features formed by distributary river 

systems are in Kings County. Sediments in this formation are of continental origin and consist mainly of 

very fine to coarse deltaic sand and silty sand with 

lesser amounts of interbedded clay. This aquifer commonly is characterized by a basal part consisting of 

coarse sand and gravel ranging from 25 to 50 ft thick. 

The Magothy aquifer is a productive aquifer with horizontal hydraulic conductivity of 60 to 90 ft/d (McClymonds and Franke, 1972). It is semiconfined at its 

northern limit in Queens County and is confined by the 

Gardiners Clay in Kings County and southern Queens 

County. As previously mentioned, the Magothy and 

Jameco aquifers are considered as one aquifer in this 

report and are termed the Jameco and Magothy aquifer.

Raritan Confining Unit

The Raritan confining unit (Raritan clay) is the 

younger of two members that form the Raritan Formation. The older member is the Lloyd Sand (Lloyd aquifer), described further on. The Raritan clay is present 

throughout Kings and Queens Counties except along 

the northern shores and in the ancestral Hudson channel, where it was removed by erosion. It is a deltaic 

deposit ranging from 0 to about 250 ft thick and consists mostly of clay, silty clay, and clayey and silty fine 

sand. It lies conformably on the Lloyd Sand Member, 

except in the northwest, where the Lloyd Sand is missing. There, the Raritan clay member lies unconformably on bedrock. This unit is referred to as the Raritan 

confining unit because it confines the underlying 

Lloyd aquifer. Vertical hydraulic conductivity is estimated to be 0.001 ft/d (Franke and Cohen, 1972).

Lloyd Aquifer

The Lloyd aquifer is the Sand Member of the Raritan Formation and, like all overlying deposits, dips 

and generally thins to the southeast. Its extent is similar to that of the overlying clay member, and it has the 

same erosional channel as the other Cretaceous units 

in the area, although it underwent the least amount of 

channel erosion. Thickness of the Lloyd aquifer ranges 

from 0 to about 300 ft. The deposits are of fluvialdeltaic origin and consist of very fine to very coarse 

sand, gravel, and interbedded clay and clayey and silty 

sand. Horizontal hydraulic conductivity ranges from 

50 to 70 ft/d (McClymonds and Franke, 1972). The 

Lloyd aquifer lies unconformably on crystalline bedrock and is confined by the overlying clay member.

METHODS

An extensive network of wells in Kings, Queens, 

and western Nassau Counties provided the data for 

this study. Water samples from wells were analyzed, 

and geophysical logs were obtained by down-hole logging equipment. The following sections describe the 

well network, water-quality data collection, and geophysical logging.

Well Network

In this report, all network wells are classified 

either as "previously sampled" or as "new"; new wells 

are those that were installed or added to the USGS 

data base after 1992. The well network consists of (1) 

public-supply wells, (2) industrial-supply wells, and 

(3) monitoring wells.

Previously Sampled Wells

The first comprehensive study of ground-water 

quality on western Long Island (Buxton and others,

6 Ground-Water Quality in Kings, Queens, and Western Nassau Counties, Long Island, New York, 1992-96, with Geophysical Logs
1981) obtained chemical analyses of water samples 

from a set of 144 wells in Kings, Queens, and western 

Nassau Counties, of which, 77 were either monitoring 

wells or industrial-supply wells (interchangeably 

called observation wells) sampled by the USGS; 

the remaining 67 wells were pubic-supply wells sampled by the Jamaica Water Supply Company (now 

owned and operated by NYCDEP). Of these 144 

wells, 93 are screened in the upper glacial aquifer, 

38 are screened in the Magothy-Jameco aquifer, and 

13 are screened in the Lloyd aquifer. Henceforth, these 

wells are termed upper glacial, Magothy-Jameco, and 

Lloyd wells, respectively.

A followup study in 1983 (Buxton and Shernoff, 

1995) obtained water-quality data from 190 wells; 106 

of these were observation wells, and 84 were publicsupply wells. Of the 106 observation wells, 53 had 

been sampled in the 1981 study, and 53 had not. Of the 

106 observation wells, 64 were screened in the upper 

glacial aquifer, 17 in the Jameco, 14 in the Magothy, 

1 in the Raritan clay, and 10 in the Lloyd aquifer. Of 

the 84 public-supply wells, 30 were screened in the 

upper glacial aquifer, 4 in the Jameco, 45 in the Magothy, and 5 in the Lloyd. Results of the inorganiccompound analyses for the 106 observation wells, and 

the inorganic-compound analyses for the 84 publicsupply wells, are given in tables 10 and 11 of Buxton 

and Shernoff (1995), respectively.

New Wells

The number of wells available for ground-water 

sampling has decreased over the years because well 

screens become clogged with silt, or the wells become 

filled with sediment, rendering them useless for sampling. Road construction and repairs also have caused 

the destruction of many wells. The 29 new USGS 

wells were installed from November 1992 through 

October 1995 to replace some of the old wells and to 

provide additional hydrogeologic information in areas 

where data were lacking. Four of these wells are 

screened in the Lloyd aquifer, 3 in the Magothy 

aquifer, 4 in the Jameco aquifer, and 18 in the upper 

glacial aquifer.

Three drilling techniques were used to install the 

new wells augering, reverse mud rotary, and air 

rotary. In addition to the 29 new USGS wells, 8 other 

wells were added to the well network; these wells 

were installed by BUG, NYCDS, or NYCDEP and 

were assigned New York State Department of Environmental Conservation well-identification numbers 

and added to the USGS data base. The drilling techniques used for their installation are unknown.

Of the 29 newly installed wells, 22 are constructed of either 2-in or 4-in poly vinyl chloride 

(PVC) pipe and 5-ft slotted screen with a 5-ft or 10-ft 

sump at the bottom. These wells have a bentonite seal 

above the screen. Five wells required air-rotary drilling; they have an outside casing of 8-in steel from land 

surface to a 75- to 100-ft depth and are constructed 

with cement seals above the screen. Two of the new 

wells consist of 1.25-in PVC pipe and 5-ft slotted 

screen, which was placed in the annular space between 

the borehole and a 2- or 4-in PVC casing. The wells 

that were installed by mud- or air-rotary techniques 

were developed by air-lifting for as long as 6 hours to 

remove fines from the sump, screen, and gravel pack.

Water-Data Collection

Two types of hydrogeologic data are presented in 

this report: (1) water-quality data (tables 3, 4), and (2) 

geophysical logs (fig. 3). The methods of ground-water 

sampling and geophysical logging are described below.

Ground-Water Sampling

Sampling devices and techniques used for collection of water samples from public-supply, industrialsupply, and monitoring wells differed because of 

differences in well construction and wellhead design.

Sampling devices and techniques. The sampling procedures used at monitoring wells were 

designed to obtain water that was representative of the 

aquifer being tapped. First, the water level was measured with a chalked steel tape. From this measurement, the depth of the water column in the casing was 

determined, and the casing volume calculated. A suction pump, submersible pump, or bailer (depending on 

the depth to water, casing diameter, and casing volume) was used to purge the well. During the purging 

process, water temperature, pH, and specific conductance were measured periodically. After the values for 

these properties had stabilized, and at least three casing volumes evacuated, the sample was collected with 

a stainless steel and Teflon submersible pump assembly or a Teflon bailer. Water samples were filtered and 

treated as required by the analyzing laboratory and

Methods 7
placed on ice for shipment. Samples from a publicsupply or industrial-supply well were generally 

obtained from a spigot or faucet (near the wellhead) 

that tapped water from the well prior to any watertreatment procedures.

Quality-assurance techniques. A tap-water 

sample and a deionized-water sample from the USGS 

laboratory in Coram, N.Y., were sent to the USGS 

National Water Quality Laboratory (NWQL) for analysis before any ground-water samples were collected 

to ensure that the water used for flushing the sampling 

devices (between samplings) was free of detectable 

amounts of all constituents to be analyzed. Next, 

deionized water was flushed through both types of 

sampling devices mentioned earlier, and a sample was 

collected and sent to the NWQL for analysis to ensure 

that the sampling devices and shipping techniques 

were not introducing detectable amounts of the constituents in question.

About 15 percent of the samples collected during 

each of the sampling periods were quality-assurance 

and quality-control (QA/QC) samples. About half of 

the QA/QC samples for the 1992-93 and 1995 sampling periods were flush blanks and (or) duplicate 

samples; the other half were spiked with a suite of 

organic constituents provided by the NWQL. About 

half of the QA/QC samples for the 1996 sampling 

period were flush blanks; the other half were duplicates. Results of QA/QC analyses are available from 

the USGS office in Coram, N.Y. Samples were not 

spiked during the 1996 sampling period because the 

organic-compound analyses were performed by a contract laboratory, which did not require spiking.

After a sample was collected, the sampling 

device was filled with a dilute acid solution and left 

to stand for about 5 min. Then it was flushed inside 

and out with deionized water. If the sampler became 

visibly dirty upon removal from a well, it was first 

washed with a Liquinox and deionized-water cleaning 

solution, followed by the standard flushing procedure. 

Typically, a flush blank was collected after this 

cleaning procedure.

Geophysical logging

Five borehole logging techniques were used in 

this study natural gamma (G), spontaneous potential 

(SP), single-point resistance (SPR), normal resistivity 

(R), and electromagnetic induction (EM). Eleven

wells were logged with at least one, and as many as 

five, of these geophysical techniques. Three wells 

were logged with all five techniques, five were logged 

only with G and EM probes, and three were logged 

only with G probes. The logs are given in figure 3. The 

SP, SPR, and R logs were always obtained in an open 

borehole; the G logs were obtained through open boreholes or through a PVC casing. The EM logs were 

always obtained through a PVC casing.

GROUND-WATER QUALITY

The water-quality data presented in table 3 (inorganic constituents, including nutrients) and table 4 

(organic compounds) constitute the most comprehensive set available for the study area. Samples from the 

first two sampling periods (August 1992 through 

January 1993, and July through September 1995) were 

analyzed for organic and inorganic compounds and for 

nutrients by the USGS NWQL; samples from the third 

period (March through July 1996) were analyzed for 

inorganic compounds and nutrients by the NWQL and 

for organic compounds by a contract laboratory. 

(Organic-compound data from the contract laboratory 

are not included here but are available from 

NYCDEP.) The first sampling period entailed resampling 87 of the 106 wells that were sampled in 1981 

and 1983 (Buxton and Shernoff, 1995); the remaining 

19 wells could not be resampled for various reasons. 

The second sampling period was designed to sample 

the newly installed wells (21 of which were installed 

and available for sampling by the end of this sampling 

period). The third sampling period entailed sampling 

101 wells (both new and old) to indicate water quality 

throughout the study area. Results of the inorganiccompound and nutrient analyses are given in table 3, 

and results of the organic-compound analyses in 

table 4. The large number of chemical constituents 

necessitated dividing each table into several groups of 

analyses 3 groups of inorganic compounds 

(tables 3A-3C), and 12 groups of organic compounds 

(tables 4A-4L). Locations of wells sampled are shown 

in figure 2. Identification numbers of sampled wells, 

and the hydrogeologic unit in which they are screened, 

are listed in table 2.

GEOPHYSICAL LOGS

Geophysical logs can be used in conjunction with 

driller's logs, cores, and water-quality analyses to help 

delineate stratigraphic boundaries and locate freshwater/saltwater interfaces. As described earlier, borehole 

geophysical logs were obtained from 11 of the new 

wells. (Locations of the logged wells are shown in

fig. 2.) Geophysical logs of the 11 wells are given in 

figure 3 with lithologic logs from drillers' notes. Chloride concentrations in water samples from selected
