1.0 INTRODUCTION
This report describes the hydrogeology of the Building 102/103/104 area, which
is located within the central portion of the Ciba-Geigy Toms River plant. At
present, the Building 102/103/104 area is a graded, grassy field. In the
past, the site contained three multi-storied chemical manufacturing buildings.
Buildings 102, 103, and 104 were built in the early 1950's. They housed
active operations until they were
demolished and removed in 1987.
phased out in the mid-1980's. They were
The only physical structures that remain·
today are subsurface foundations and concrete slabs.
The purposes of this hydrogeologic investigation are to describe the site
geology, hydrogeology, soil quality, and groundwater quality from the ground
surface to a depth of 80 feet. These goals have been achieved through three
phases of work performed during the period from November 1987 to March 1988.
The first phase comprised 33 test pits and ten soil organic analyses. The
second phase included 16 "deep" soil organic analyses acquired from samples
taken over a depth range of 10 to 68 feet. The third phase included the
construction and sampling of·eight monitoring wells screened in two aquifers.
This report follows with Section 2.0, wherein the methods and procedures of
the three phases of work are discussed within their own subsections.
Section 3.0 provides a hydrogeologic description of the Building 102/103/104
area based on all available data. Section 4. 0 provides three subsections
containing the analytical 'results derived during each of the three phases of
soil and groundwater sampling. The report summary is provided in Section 5.0.
Appendices are contained in Volume II and include the we 11 and boring logs,
test pit logs, test pit analytical reports, deep soil analytical reports, and
groundwater analytical reports .

2.0 METHODS AND PROCEDURES
The study of the Building 102/103/104 area proceeded in three phases: 1) an
initial investigation of surficial soil quality performed through test pits;
2) a deep soil quality investigation performed through split-spoon sampling;
and 3) a groundwater quality investigation completed through monitoring well
construction. The methods and procedures used in each of these phases are
discussed below in the following three sections.
2. 1 TEST PITS
Thirty-three test pits were successfully excavated and sampled during November
1987 (Figure 2-1). Volume II, Appendix B presents the test pit field logs for
all 33 test pits. The original work plan called for 45 test pits to be
excavated, but 12 of these were located on sites containing concrete within
two feet of the ground surface.
achieved at these 12 locations.
Thus, no significant penetration could be
Of the 33 successful test pits, samples from
ten test pits were selected and were analyzed for Priority Pollutant Plus
Forty organics.
A backhoe was used to dig the pits. The procedure consisted of excavating
down to three feet, extracting soil with the backhoe bucket, and then placing
soil into a sample jar. The backhoe then proceeded to five-feet depth, where
a second sample was taken. In addition, analytical samples were taken at the
five-foot depth and placed into pre-cleaned jars.
A photoionization test was performed on a soil sample fx:om each test pit at
both depths by extracting an air sample from a sealed jar approximately
one-half full of soil. The air sample was drawn into an HNU Inc.
photoionization meter. This meter responds to the presence and concentration
of many organic compounds. The reading is recorded in ppm units and provides
a qualitative determination of the presence of volatile organics.
Ten samples were selected on the basis of both field photoionization and soil
discolor~tion, and were shipped to the laboratory for Priority Pollutant Plus

2.2 DEEP SOILS
Sixteen deep soil samples were acquired from the Building 102/103/104 area and
sent to the laboratory for Priority Pollutant Plus Forty organic analyses.
The samples were taken with split-spoon samplers in January 1988 during
construction of eight monitoring wells. The samplers were decontaminated with
a soap and water wash and a deionized water rinse prior to use. The well
locations are shown on Figure 2-1 and cluster into five locations as follows:
0 Wells 1140 and 1141
0 Wells 1142 and 1143
0 Wells 1144 and 1145
0 Well 1146
0 Well 1147
The sixteen deep soil samples were collected from three hydrostratigraphic
zones:
o Unsaturated Upper Cohansey Sand
o Saturated Upper Cohansey Sand
o Saturated (or at least sampled a portion of the saturated) Primary
Cohansey Sand.
The discussion of these hydrostratigraphic zones are found within the
hydrogeology section of this report (Section 4.0). For a more detailed
hydrogeologic discussion of the entire plant site, see AWARE, 1986. The
sixteen soil samples were sent to the laboratory for Priority Pollutant Plus
Forty organic analyses.
The analytical results are discussed in Section 4.2. The original laboratory
reports are presented in Volume II, Appendix D .

2.3 GROUNDWATER
Eight monitoring wells were installed in the Building 102/103/104 area during
January 1988 (Figure 2-1). These eight wells were constructed in five
locations. Each location contains one shallow, Upper Cohansey Sand well.
Three of these five locations contain an addi tiona! deeper, Primary Cohansey
Sand well. For further discussion of these two hydrostratigraphic zones, see
Section 3.0.
1986.
For further definition of plant-wide hydrogeology, see AWARE,
The five Upper Cohansey Sand wells were constructed by hollow-stem auger
techniques. Continuous soil sampling was performed with the use of two..;.foot
long, two-inch diameter, split-spoons driven with a conventional 140 pound
hammer. Sampling proceeded until the Cohansey Yellow Clay was encountered at
an approximate depth range of 27 to 29 feet. The Cohansey yellow clay
determines the base of the Upper Cohansey Sand, as defined by AWARE, 1986.
Four-inch diameter, 10-foot long, stainless steel screens were placed at the
top of clay. An appropriate length of four-inch diameter, carbon steel riser
was added to the top of each screen and cut at approximately two feet above
the ground. The screen was packed with clean gravel, a two-foot thick
bentonite pellet seal was placed above the gravel, and a cement-bentonite
grout was tremied to the surface. Protective casing was added, and the wells
were developed by air surging until the water appeared clear.
The deeper wells were constructed with mud-rotary techniques. Eight-inch
surface casing was set at the top of the Cohansey Yellow Clay and cemented in
place. The drill bit then proceeded beyond the clay and into the Primary
Cohansey Sand. Split-spoon samples were taken at selected locations to ensure
that the wells would be set at the base of the Primary Cohansey Sand. Once
the desired depth was reached, the wells were constructed in a similar manner
to the shallow wells. All logs from each of the eight wells are presented in
Volume II, Appendix A.

hydroxides, nitrate-N, and TOC. The analytical results are presented in
Section 4.3. The original laboratory reports are shown in Volume II,
Appendix E .

3.0 SITE HYDROGEOLOGY
The hydrogeology of the Building 102/103/104 area was primarily investigated
through split-spoon sampling and water level measurements -made at the five
well construction locations. Three of the deepest wells offered soil sampling
to a depth of 80 feet. Four hydrostratigraphic units and two aquifers were
addressed in this 80-foot section. Starting from the ground surface, these
four units are identified as follows (AWARE, 1986):
o Upper Cohansey Sand
o Cohansey Yellow Clay
o Primary Cohansey Sand
o Cohansey/Kirkwood Transitional Unit
All of these hydrostratigraphic units fall within the single layer termed by
the USEPA as the Upper Sand Unit, which is reported to lie between the ground
surface and a depth of approximately 160 feet (USEPA, 1988) .
This hydrogeologic report of the Building 102/103/104 area describes a
relatively small area when contrasted to the entire Ciba-Geigy Toms River
plant site. When the findings of this smaller report are objectively compared
within the framework of an important larger study (AWARE 1986), no significant
interpretations emerge. This smaller study of the Building 102/103/104 area
only refines the more encompassing descriptions and interpretations.
The five borings performed during construction of the shallow wells for the
Building 102/103/104 study found 1 ight ly colored, coarse-to-fine sand, with
traces of gravel and silt extending from the ground surface to a depth of 27
to 29 feet. Yellow and gray clay was encountered below with a thickness
ranging from four to six feet. Perched water lay above this clay and ranged
from zero to nine feet in thickness. The clay is recognized as the Cohansey
Yellow Clay, the overlying sand is the Upper Cohansey Sand, and the perched
water constitutes the Upper Cohansey Sand Aquifer (Figures 3-1 through 3-4).
Water level measurements taken within the five subsequently installed Upper
Cohansey Sand monitoring wells demonstrate groundwater flow towards the

northeast with a gradient as high as 0.05 (Figure 3-2). The aquifer is
thickest beneath the Building 102 area and thins in the direction of flow
(Figure 3-4). Well 1147, the easternmost Upper Cohansey Sand monitoring well
installed for this investigation, was set on top of the Cohansey Yellow Clay
'&nd remains dry. Its well screen is set below the horizon that contains
groundwater in wells 1143 and 1146. These observations indicate that flow in
the Upper Cohansey Sand aquifer is moving towar.d an apparent break in the
clay, a break which appears to be located just west of well 1147. In other
words, the groundwater within the Upper Cohansey Sand aquifer appears to flow
towards the break in the clay and migrate vertically down to the next aquifer
below.
The existence of the break in the Cohansey Yellow Clay at this location has
been previously suggested AWARE ( 1986), where a 250-foot wide, 1 inear break
in the clay trending northwest across the site is shown on their Figure 4-22.
This clay break has been found and reported in a variety of borings at other
locations within the plant, but never has the break been found at the Building
102/103/104 area. Although the break still remains unconfirmed at the
Building 102/103/104 area, the evidence for its existence, based on water
levels and clay surface configuration uncovered in this study, remains strong.
Three borings penetrated the Cohansey Yellow Clay for this study and
encountered the Primary Cohansey Sand. This unit is texturally much like the
Upper Cohansey Sand and generally would be described as lightly colored,
coarse-to-fine sand, with traces of gravel and silt. The unit is
approximately 40 feet thick. Approximately 38 feet of the unit was found to
constitute the Primary Cohansey Sand aquifer. Two to three feet remain
unsaturated below the base of the Cohansey Yellow Clay. Thus, the Upper
Cohansey Sand aquifer, which lies above the clay, is identified as perched.
The Primary Cohansey Sand aquifer flows to the northeast at a gradient of
0.001 (Figure 3-5). This flow is consistent with regional water table maps.
The deepest hydrostratigraphic unit encountered in this study is the
Cohansey/Kirkwood Transitional Unit found at a depth of 72 to 75 feet. This
unit is a gray, very fine sand and silt.

4.0 ANALYTICAL RESULTS
The following three subsections present the analytical results for the three
phases of analytical sampling performed for the Building 102/103/104 study.
The analytical results achieved through test pit sampling are addressed first.
4.1 TEST PITS
Ten test pit soil samples were selected from 33 test pits and sent to the
laboratory for Priority Pollutant Plus Forty organic analyses. Figure 4-1
shows the location of the ten test pit samples sent to the laboratory. Five
out of ten of these samples were selected from within the former Building 102
area.
Table 4-1 summarizes the analytical results. The organics found primarily
consist of semivolatile organics, and thus Table 4-1 is labeled as such.
Twenty targeted semivolatile organic compounds were found above the detection
limit. Only one sample, TP-9, contained any volatile organics. TP-9 had two
vola tile organic compounds, both of which were non targeted. The or igina 1
analytical reports containing the test pit results are shown in Volume II,
Appendix C.
4.2 DEEP SOILS
Sixteen soil samples acquired from split-spoons were analyzed for Priority
Pollutant Plus Forty organics. Ten of these samples were from the Upper
Cohansey Sand and six were from the Primary Cohansey Sand. All analytical
results are presented in Tables 4-2 and 4-3. These two tables are formatted
to show results in hydrostratigraphic order. The samples taken from the
unsaturated zone within the Upper Cohansey Sand which range from 12 to 28 feet
in depth, are presented at the top of the tables. The deepest samples taken
from the saturated portion of the Primary Cohansey Sand, which range from 64
to 68 feet in depth, are presented near the bottom of the tables.

targeted volatile organics, only two compounds were found above detection
limits. These were methylene chloride at 450 and 480 ppb in the sat.urated
zone of the Upper Cohansey Sand and nitrobenzene found once at 470 ppb in the
Primary Cohansey Sand. Nitrobenzene is sometimes considered a semivolatile
compound. The non targeted 1 ibrary search revealed vola tile organics within
the Upper Cohansey Sand aquifer at concentrations collectively as high as
130,000 ppb.
Table 4-3 presents a summary of results for Priority Pollutant semivolatile
organics, including the nontargeted 1 ibrary search. The Upper Cohansey Sand
aquifer contains 12 targeted volatile organics and nontargeted compounds that
reach total concentrations as high as 141,200 ppb. These diverse semivolatile
compounds at relatively high concentrations provide a stark contrast to the
water quality within the Primary Cohansey Sand aquifer, which lies below.
This lower aquifer contains no targeted semivolatile organics above the
detection limit.
4.3 GROUNDWATER
Seven out of eight monitoring wells installed for this study were sampled and
analyzed for Priority Pollutants and a broad suite of general parameters. One
well, monitoring well 1147, could not be sampled because it was dry. Of the
seven successful samples, four are from the Upper Cohansey Sand aquifer and
three are from the Primary Cohansey Sand aquifer. All groundwater results are
presented in Tables 4-4 through 4-7. Complete laboratory analytical reports
are provided in Volume II, Appendix E.
The results of the Priority Pollutant volatile organic analyses are presented
on Table 4-4. Seven targeted volatile compounds were found above the
detection limit in the Upper Cohansey Sand aquifer. In contrast, only one
volatile compound was found in the Primary Cohansey Sand aquifer.

Semivolatile compounds found in the groundwater are shown in Table 4-5. The
Upper Cohansey Sand aquifer contains ten semivolatile compounds found above
their detection limit. The Primary Cohansey Sand, again in contrast to the

Priority Pollutant metals for the two aquifers are shown in Table 4-6.
General chemistry parameters are shown in Table 4-7. The results shown in
these two tables parallel the findings of organic compounds. Most metals and
general chemistry compounds have higher concentrations in the Upper Cohansey
Sand aquifer relative to the Primary Cohansey Sand aquifer.
Although tested for, no Priority Pollutant pesticides or PCBs were found in
any sample. No tabular results, therefore, are presented for these compounds .

5.0 SUMMARY
The hydrogeologic investigation of the Building 102/103/104 area proceeded in
three phases: 1) An initial investigation of surficial soil quality performed
through 33 test pits; 2) a deep soil quality investigation through split-spoon
sampling at 5 locations; and 3) a groundwater investigation completed through
the construction of eight monitoring wells. These three phases of work have
resulted in a comprehensive understanding of the site hydrogeology, soil
quality, and groundwater quality from the ground surface to a depth of
approximately 80 feet. The two water-bearing units addressed are the Upper
Cohansey -Sand and the Primary Cohansey Sand. The hydrogeologic findings of
this study strongly reinforce the observations and interpretations reported by
the more encompassing hydrogeologic investigation produced by AWARE (1986).
The soil and water quality of the uppermost water-bearing zone, the Upper
Cohansey Sand, was addressed by all three work phases. Analytical results
from this zone provide a relatively consistent pattern of contamination
dominated by semivolatile organic compounds. The test pits contained 20
targeted semivolatile compounds above detection limits, deep soil samples
contained 12, and groundwater had 10. In addition, a variety of nontargeted,
unknown semivolatile compounds were detected.
Volatile organics within the Upper Cohansey Sand proved to be more rare and of
lesser concentration than the semi volatile organics. No targeted volatile
organics were found above the detection limit in either the test pits or the
deep soil samples. Groundwater samples, however, did reveal seven volatile
organic compounds above the detection limit, but these were relatively low in
concentration when contrasted to the semivolatile group.
The quality of the Primary Cohansey Sand was addressed through both the deep
soil and groundwater phases of the study. In general, the unit is found to be
relatively free of organic compounds when contrasted to the overlying Upper
Cohansey Sand. Targeted volatile organics above the detection 1 imi t within
the Primary Cohansey Sand were limited to 470 ppb nitrobenzene in one deep
soil sample and 12 and 18 ppb chlorobenzene found in two wells. Semivolatile
organics within the Primary Cohansey Sand groundwater were limited to four
compounds individually not exceeding 100 ppb concentration.
