1.0 SITE IDSTORY AND SOURCE CHARACTERIZATION
Conoco Store No. 33047 is located at 1122 North Raleigh Street adjacent to East Grand Avenue in
Rocky Mount, Edgecombe County, North Carolina. A 7. 5-minute United States Geological Survey
(USGS) topographic quadrangle map denoting the site is provided as Figure I. The site is bounded
to the north and northeast by East Grand Avenue (Figure 2). Across East Grand Avenue northeast
of the site is a Hardees Restaurant. A gasoline station/convenience mart is located diagonally
across the intersection of East Grand Avenue and North Raleigh Street, southeast of the site.
Located southeast of the site across North Raleigh Street is an Edgecombe County Alcoholic
Beverage Control Store. To the south of the site across North Raleigh Street is a vacant lot which
may have been formerly occupied by a self service car wash facility. Adjacent to the site in a
westerly direction is a private residence. A list of area property owners is provided in Table I; the
properties described above are identified on Figure 3.
Currently, located on site are three 10,000-gallon fiberglass underground storage tanks (USTs)
containing unleaded, unleaded plus and super unleaded fuels. A 5,000-gallon UST which had
contained kerosene fuel, and four gasoline dispensers were removed and replaced at the site in
March 1994. The kerosene UST was replaced with a 4,000-gallon double-walled fiberglass UST.
Law Engineering, Inc. (LAW) was requested by Conoco in March 1994 to observe the excavation
and removal of the former UST and dispensers.
As detailed in LAW's Underground Storage Tank System Closure Report, dated August 3, 1994, a
LAW field representative on site during field activities observed the removal of the kerosene UST.
Results of the laboratory analysis of soil samples collected during removal activities indicated that
the soils in the vicinity of the kerosene UST had been impacted by hydrocarbons above North
Carolina allowable limits. Soils excavated from the basin and from beneath the dispensers were
transported to the Stalite Environmental facility in Salisbury, North Carolina for recycling;
approximately 55 tons of soil was transported and recycled. Results of laboratory analyses of a
ground-water sample collected from the UST basin during removal activities indicated that ground
water in the vicinity of the basin had not been impacted by hydrocarbons at levels above North
Carolina standards.

Final
At the request of Conoco, representatives of LAW visited the site on April 27, 1994. The store
manager reponed the occurrence of free product in the subsurface in the vicinity of the gasoline
dispenser area. Free product was observed at the edge of the concrete pad underneath the canopy
and flowing across the pavement. A leaking shear valve in gasoline pump No. I was thought to be
the source of product, and was subsequently replaced on April 27, 1994. The valve was later
tested for tightness and maintained pressure. On April 28, 1994, a pressure test was performed on
the gasoline product lines. This test indicated a leak was present in one line near gasoline pump
No. 4. This leak was subsequently repaired.
As an initial abatement activity, LAW excavated a temporary sump at the downgradient edge of the
concrete pad/dispenser area. Subsequently, a four foot deep collection well, consisting of two feet
of PVC slotted well screen and two feet of PVC riser pipe, was installed in the hole. A locking cap
and a flush-mounted well vault were installed over the well. Product recovery activities were
initially performed twice a week. A representative from our LAW office in Raleigh, North
Carolina visited the site to measure the depth -of product in the well, remove by bailing any
accumulated product, and emptying the product into a 55-gallon storage drum located on site. Due
to lesser amounts of product being recovered, site visits to bail product were reduced to a weekly
basis and subsequently to a monthly schedule. Approximately 15 gallons of product have been
recovered from the collection well to date. LAW has subsequently discontinued product recovery
activities at the request of Conoco.
In July 1994, Target Environmental Services (Columbia, Maryland) performed a soil/gas survey
and collected soil and ground-water samples utilizing a Geoprobe. Results of the soil gas survey
are detailed in the report of Soil Gas Survey and Soil and Groundwater Sampling, prepared by
Target, dated August 1994 (included as Appendix A). As detailed in the report, two areas on site
were indicated to have high concentrations of volatiles in soils: the vicinity of the current UST
basin, and the northeast corner of the property. The geoprobe activities performed included
collection of soil and ground-water samples for laboratory analysis. Results of the laboratory
analyses of soil samples collected during geoprobe activities indicated that the areas of
hydrocarbon-impact in soils were in the vicinity of the UST basin. Results of analysis of ground-
water samples collected during geoprobe activities indicated that the ground water has been
impacted by hydrocarbons at levels above North Carolina standards.

2.0 POTENTIAL RECEPTORS AND MIGRATION PATHWAYS
2.1 WATER WELL SURVEY
The immediate vicinity of the Conoco site located in the North Raleigh Street/East Grand Avenue
area of Rocky Mount, North Carolina is serviced by city water, according to Mr. Paul Blount, the
director of the City of Rocky Mount Water Resources Department. During a telephone
conversation between Mr. Blount and Ms. Kelly McBride of LAW on January 17, 1995, Mr.
Blount stated that this particular area was probably one of the first areas in Rocky Mount to be
serviced with public water, but he was unsure of the date of incorporation.
Mr. Blount also stated that to his knowledge there are no private water-supply wells located within
the city limits. In order to verify this information, a survey of water-supply wells potentially
located within a I ,500-foot radius of the Conoco site was performed on November 30, 1994 by a
LAW representative. No confirmed water-supply wells were noted at the residences or businesses
located within the 1 ,500-foot radius during the survey of the area. The area appears to be primarily
residential with some commercial businesses. The area of the water well survey is shown on
Figure 4.
2.2 MONITORING WELL SURVEY
A survey of off-site monitoring wells within a 1 ,000-foot radius of the Conoco site was performed
November 22, 1994 by a LAW representative. During this survey, nineteen monitoring wells were
identified on properties surrounding the site. The locations of these wells are denoted on Figure 4.
2.3 AREA WATER SUPPLY
According to Mr. Paul Blount with the City of Rocky Mount Water Resources Department, the city
receives water from the Tar River Reservoir or directly from the Tar River. The Tar River
Reservoir is approximately eight miles southwest of the site (Figure 1). The Tar River flows within
4,000 feet of the site at its closest point. The river is located downgradient of the site to the north.

Water mains, catch basins and gas lines observed in the vicinity of the Conoco site are noted on
Figure 5. These locations are approximate and the depth of burial of these lines is not known. The
location of the water main was taken from a portion of a map provided by the City of Rocky Mount
(date unknown). The location of the gas line was verified by Mr. Ike Fowler, Gas Superintendent
of Rocky Mount, in a telephone conversation with Ms. Kelly McBride of LAW on January 26.
1995.
No building basements are located on the properties located immediately adjacent to the site. No
basement is located at the Conoco site.

3.0 AREA GEOLOGY
February 6, /995
Final
The project site is located in the Atlantic Coastal Plain Physiographic Province. In general, the
sediments of the Coastal Plain consist of interbedded sands, clays, calcareous clays, shell beds,
sandstone, and limestone (LeGrand, 1959). These sediments are generally layered in interfingering
sand beds and clay lenses that gently dip and thicken to the east. In the Rocky Mount area, the
Coastal Plain sediments are about I 00 to 300 feet thick and apparently overlie igneous and
metamorphic basement rocks of the Piedmont Physiographic province. These sediments were
apparently deposited in marine or near-marine environments.
According to the Geologic Map of North Carolina (1985), the site is located in the Yorktown
Formation which consists of fossiliferous clay with varying amounts of fine-grained sand. It is
typically bluish gray with shelly material commonly found in lenses. The Yorktown Formation is
underlain by the Duplin Formation which consists of shelly medium to coarse sand, sandy marl and
limestone. The site is also located near the Tar River where the underlying Cape Fear Formation is
exposed due to erosion of the overlying sediments. This formation consists of yellow gray to bluish
gray, mottled red to yellowish orange graded sands that are locally indurated (NCGS, 1985).
In general, downward movement of ground water within Coastal Plain sediments is obstructed by
the presence of clay layers in Coastal Plain formations and consequently most of the ground-water
recharge migrates laterally toward discharge areas through the surficial aquifer (Heath, 1980).
In the Rocky Mount area, sediments deposited in marine or near-marine environments are about
I 00 to 300 feet thick and overlie igneous and metamorphic basement rocks according to the 1985
Geologic Map of North Carolina. The aquifers of the Rocky Mount area are the surficial and the
Cape Fear aquifers. They are separated by less permeable clay and silt beds (confining units) that
may impede the flow of ground water between the aquifers.
The surficial aquifer in the northern portion of the Coastal Plain consists of Pleistocene deposits that
are comprised of fine to coarse sand and silty sand grading to a clayey sand or sandy clay at depth
(Winner and Coble, 1989). The surficial aquifer is relatively shallow in this area and commonly
extends to depths of 10 to 40 feet. This unit is typically not used for water supply in the area.

Final
There are two principal water-supply aquifers for the area surrounding the site. The Yorktown
aquifer occurs beneath the surficial aquifer and consists of fine sand, silty sand and clay and is
characterized by pervasive shells and shell beds. This aquifer overlies the Upper Cape Fear aquifer
which consists of alternating beds of clay and sand. The upper Cape Fear confining unit separates
the Yorktown aquifer from the underlying Upper Cape Fear aquifer. The confining unit generally
consists of nearly continuous clay, silty clay and sandy clay beds.
Water levels in wells tapping the surficial aquifer vary seasonally. The surficial aquifer receives
more recharge in the winter than in the summer when much of the water evaporates or is transpired
by plants before it can reach the water table. Therefore, the water table generally is highest in the
winter months and lowest in the summer or early falL

4.0 FIELD EXPLORATION
February 6, 1995
Final
The field exploration conducted at the site included performing a soil gas survey, collecting soil and
ground-water samples using a geoprobe, and installing eight monitoring wells.
Collection points for soil/gas samples were chosen by Target; soil/gas samples were collected and
analyzed for hydrocarbons by Target personneL Procedures and results of activities are detailed in
Target's Report of Soil/Gas Survey and Soil and Ground Water Sampling (attached as Appendix
A).
Geoprobe sample collection points were selected by LAW personnel and Conoco based on
preliminary soil/gas survey data and site accessibility. The results of these activities were detailed
in LAW's Preliminary Assessment Repon, dated November 22, 1994.
The boring locations for the eight monitoring wells were selected in the field by LAW personneL
These locations were selected based on existing site conditions, estimated ground-water flow
direction and accessibility of the drill rig. The locations are shown on Figure 2.
Following installation, the wells were located in the field and elevations for the wells were
measured using a level and graduated rod. These elevations· were referenced to an assumed site
datum (top of casing of well MW-7 = 100 feet). The locations and elevations for the borings and
wells should be considered accurate only to the degree indicated by these methods.
4.1 SOIL TEST BORiNGS AND MONlTORlNG WELL INSTALLATION
Eight soil test borings have been performed at the site. Borings MW-1 through MW-8 were drilled
by LAW. The borings were drilled using a truck-mounted drill rig employing continuous flight
hollow-stem augers to advance the boreholes. During drilling, soil sampling and penetration testing
were performed in general accordance with ASTM 0-1586. At regular intervals, soil samples were
obtained with a standard 1.4-inch 1.0., 2-inch 0.0., split-spoon sampler.

Final
Representative portions of the soil samples recovered from the borings were scanned with an
organic vapor analyzer (OVA) and classified in the field by LAW personnel. Test boring records
showing the soil descriptions and penetration resistances for each boring are included in Appendix
B. To reduce the potential for cross-contamination between borings, downhole drilling equipment
was steam cleaned prior to drilling each boring.
Type II (shallow) ground-water monitoring wells were installed in boreholes MW-1 through MW-4
and MW-6 through MW-8 to depths ranging from 19 feet to 24 feet. A Type III (deep) monitoring
well was installed in borehole MW-5 to a depth of 53 feet in order to assess the vertical extent of
hydrocarbon impact.
The Type II ground-water monitoring wells (MW-1 through MW-4 and MW-6 through MW-8,
Figure 2) consist of two-inch diameter PVC pipe (Schedule 40 with flush-threaded joints) inserted
into ten-inch diameter augered boreholes. The bottom 15-foot section of each monitoring well is a
manufacntred well screen with 0.010-inch slots. The well screens were set to intercept the
saturated/unsaturated zone interface encountered at the time of drilling. Washed sand backfill was
placed around the outside of the pipe to approximately one-foot above the top of the well screen.
The sand backfill is used to stabilize the fortnation and to help yield a less turbid ground-water
sample. A bentonite seal (minimum one-foot thick) was installed on top of the sand backfill to seal
the monitoring well at the desired level. The borehole was then grouted with a Portland
cement/bentonite mixture to the ground surface. A lockable well cap was installed and a flush
mounted protective steel cover was cemented in-place over each monitoring well.
The Type III monitoring well (MW-5) consists of a ten-inch diameter augered borehole advanced
through the overburden soils to a depth of 45 feet below the ground surface using hollow stem
augers. Four-inch diameter PVC pipe was installed to the tertnination depth of the borehole. The
annular space between the borehole and the four-inch PVC pipe was grouted with a
cement/bentonite grout to near ground-surface and allowed to cure for 24 hours.
After the grout around the four-inch PVC casing had cured, a four-inch diameter borehole was then
advanced to approximately eight feet below the bottom of the four-inch casing using rotary wash
drilling procedures. Two-inch diameter PVC casing with a five-foot (0.010-inch slots)

manufactured screened section at the bottom was installed through the four-inch casing and into the
washed borehole. A sand-pack was constructed around the pipe to several feet above the screen,
followed by an approximately two-foot thick bentonite seal. Above the bentonite. the annular space
was filled with grout to the ground surface. The monitoring well installation records for Type ll
and Type lli wells are provided in Appendix C.
Measuring point and ground-water elevations were determined by measuring the top of each PVC
well casing relative to an on-site datum, measuring the water level in each monitoring well and
computing the reference elevation of the ground water at the time of measurement. A summary of
the ground-water elevation data is included as Table 3.

5.0 SUBSURFACE CONDITIONS
February 6, 1995
Final
Eight soil test borings (MW-1 through MW-8, Figure 2) and ten geoprobe borings (GP-1 through
GP-10; Figure 8) have been performed at the site. The eight soil test borings were subsequently
completed as monitoring wells; the geoprobe borings were performed in order to estimate the extent
of the hydrocarbon-impacted soil on the site. -The soil analytical results are summarized in Table 2.
The borings generally encountered residual soils from ground surface. The residual soils
encountered generally consisted of loose to firm sands, firm to very stiff clays and stiff to hard silts.
Partially weathered rock was encountered in boring MW -5 between 39 and 45 feet below ground
surface. Subsurface profiles detailing subsurface conditions are provided as Figures 6 and 7.
Ground-water levels were measured in the monitoring wells on December 16, 1994. The ground-
water measurements are summarized in Table 3. Ground-water levels may fluctuate several feet
with seasonal and rainfall variations and with changes in the water level of adjacent drainage
features. Normally, the highest ground-water levels occur in late winter and spring. The lowest
levels occur in late summer and fall. Ground-water measurements for monitoring wells screened in
the surficial, unconfined aquifer are presented on the ground-water contour map on Figure 12.
The above descriptions provide a general summary of the subsurface conditions encountered. The
test boring records (Appendix A) contain detailed information recorded at each boring and include
our interpretation of the subsurface conditions based on examination of the field samples. The lines
designating interfaces between strata represent approximate boundaries and the transition between
strata may be gradual.

6.0 SOIL AND GROUND-WATER SAMPLING AND TESTING
The following sections detail soil and ground-water sampling and testing activities performed at the
site.
6.1 SOIL SAMPLING AND ANALYSIS
Soil samples for laboratory analysis were not collected during well installation due to the collection
of numerous soil samples during geoprobe activities performed at the site in August 1994. Soil
samples were obtained from borings GP -1 through GP-10 (Figure 8). The samples were analyzed
for total petroleum hydrocarbons-volatile constituents (EPA 5030/8015M). Selected samples were
also analyzed for total petroleum hydrocarbons semi-volatile constituents (EPA 3550/8015M). The
results were originally submitted as part of LAW's November 22. 1994 report; they are reproduced
in Table 2; the laboratory analytical report and chain-of-custody laboratory records are provided in
Appendix D.
6.2 GROUND-WATER SAMPLING AND ANALYSIS
Following stabilization of the water levels in the monitoring wells. water levels were measured in
each well with an electric water-level indicator to determine depth to the water surface. The
measured water depth was used in conjunction with the total casing depth to determine the height of
the water column and the volume of water standing in each monitoring well.
The monitoring wells were developed by bailing until the water's turbidity was reduced and it was
determined that each monitoring well was functioning properly. Bailing was continued until a
volume of water equal to at least six times the volume of water in the well casing under static
conditions was removed or until all accessible well water was evacuated.
The monitoring wells were sampled on December 16, 1994. A trip blank prepared in the
laboratory was maintained for quality assurance purposes. The ground-water samples and trip
blank were placed on ice and sent via overnight carrier to Law Environmental National
Laboratories in Kennesaw, Georgia for laboratory analysis. The ground-water samples from the

December 16, 1994 sampling event were analyzed for benzene, toluene, ethylbenzene and xylenes
(BTEX), methyl-tertiary-butyl ether (MTBE) and isopropyl ether (IPE) by EPA Method 602;
purgeable halocarbons by EPA Method 601; ethylene dibromide (EDB) by EPA Method 504; and
lead by EPA Method 30306. Laboratory test results for the sampling event are summarized in
Tables 4 and 5. The laboratory analytical report and chain-of-custody records are provided in
Appendix E.
6.3 INFLOW PERMEABILITY TESTS
Inflow permeability tests were performed on monitoring wells MW-3 and MW-8 to estimate the
hydraulic conductivity of the formation materials exposed to the screened interval at the monitoring
well location. Hydraulic conductivity is a constant of proportionality relating to the ease with
which a fluid passes through a porous medium. The field procedure to calculate the hydraulic
conductivity is as follows:
• Measure the depth to the ground water;
• remove water from the borehole by bailing; and
• measure the ground-water recovery rate.
The field tests were conducted on December 16, 1994. Results of the field testing are discussed in
Section 7.3; calculations are included in Appendix F.

7.0 TEST RESULTS AND EVALUATION
The following sections discuss the results of soil and ground-water analyses.
7.1 SOlL ANALYTICAL RESULTS
February 6, /995
Final
Soil samples collected during geoprobe activities in August 1994, were analyzed for TPH-volatile
constituents: selected soil samples were analyzed additionally for TPH semi-volatile constituents, as
discussed in Section 6.!. Levels of hydrocarbons were above North Carolina allowable levels at
one collection point, GP-3. The results of the analyses are summarized in Table 2. These results
were also detailed in our Preliminary Assessment Report, dated November 22. 1994.
7.2 GROUND-WATER ANALYTICAL RESULTS
Ground-water samples collected during the sampling event on December 16, 1994, were analyzed
as detailed in Section 6.2. The results of the analyses are summarized in Tables 4 and 5. The
results of the analyses indicate that ground water at this site has been impacted by hydrocarbons and
other chlorinated compounds. A total BTEX isopleth map, a benzene isopleth map and an MTBE
isopleth map are provided as Figures 9, 10 and II, respectively.
Concentrations of benzene, toluene, ethylbenzene and xylenes above North Carolina ground-water
standards (as listed in NCAC Title 15A, Subchapter 2L, and provided in Table 4) were detected in
wells MW-1, MW-2, MW-3 and MW-7. Only the ground-water standard for benzene was
exceeded in wells MW-1 and MW-3. MTBE was detected at a concentration above the North
Carolina ground-water standard in wells MW-2, MW-7 and MW-8. Hydrocarbons were non-
detectable or below ground-water standards in wells MW-5, MW-6 and MW-8. Concentrations of
lead exceeded North Carolina ground-water standards in wells MW-3 and MW-8. Chloroform was
detected above the North Carolina standard in well MW-5. Tetrachlorethene was detected above
the North Carolina standard in well MW-2.

7.3 HYDRAULIC CONDUCTIVITY
February 6, 1995
Final
The hydraulic conductivity of the formation materials was estimated at 2 x 10·3 to 2 x 104 em/sec
based on data recorded during field testing on December 16, 1994. The test results are as follows:
MW-3 94.05 -79.05
MW-8 91.98-76.98

Data were reduced and the hydraulic conductivities computed using techniques described in
Bouwer (1989) and, Bouwer and Rice (1976).
Calculations for hydraulic conductivity are included in Appendix F.
7.4 GROUND-WATER MOVEMENT
Ground-water movement is often related to topography, lithology, elevation of recharge and
discharge areas and man-made influences. Referenced ground-water elevations were determined by
measuring the top of the monitoring well casing relative to a nearby, on-site datum elevation (top of
casing of well MW-7 = 100 feet), measuring the water level in the monitoring well, and computing
the reference elevation of the ground water at the time of measurement.
Directions of ground-water flow were interpolated between monitoring wells by comparing the
ground-water elevations at those locations considering the factors listed above. Ground-water levels
typically fluctuate with seasonal and rainfall variations.

Final
Ground-water elevation data for the December 16, 1994 sampling event were plotted and a ground-
water contour map of the surficial aquifer was prepared (see Figure 12). The generalized direction
of the ground-water flow at the site is to the northwest as shown on Figure 12. The data points
used to prepare the ground-water contour map (ground-water elevations in site monitoring wells)
are summarized in Table 3.
Hydraulic gradients were determined by dividing the difference in ground-water elevation at two
locations by the horizontal distance between the two locations. The average hydraulic gradient at
the site was computed to be approximately 0.0605 foot/foot.
In addition to hydraulic gradients (i), the rates of ground-water movement (v) are a function of
hydraulic conductivity (k) and effective porosity (ne), as indicated by the equation v=ki/ne. The
effective porosity can be expected to be approximately 20 to 30 percent for the silty clays and
clayey sands at this site. Based on those parameters, the average lateral ground-water movement in
the silts at the site can be expected to be between approximately 42 to 64 feet per year. The rate of
migration of the dissolved organic constituent(s), however, may be substantially slower than ground
water itself, due to retardation and intrinsic aerobic biodegradation. Hydraulic calculations are
provided in Appendix F.

8.0 SUMMARY OF COMPREHENSIVE SITE ASSESSMENT ACTIVITIES
8.1 SOIL
Results of the assessment activities performed to date indicate that soils at the site have been
impacted by hydrocarbons at levels above North Carolina Standards; however, the area of impact
appears to be limited to the vicinity of the former kerosene UST.
8.2 GROUND WATER
Based on the results of the assessment activities performed to date, it appears that ground water
at the site has been impacted by hydrocarbons at levels above North Carolina allowable levels.
The highest concentrations of compounds were detected in wells MW-2 and MW-7. The plume
of impacted ground water appears to be sufficiently defined in the horizontal direction to the
northeast, east, southwest and south. The plume of impacted ground water appears to be defined
in the vertical direction.

9.0 QUALIFICATION OF REPORT
February 6, 1995
Final
The activities and evaluative approaches used in this report are consistent with those normally
employed in hydrogeological assessment and remediation projects of this type. Our evaluation of
site conditions has been based on our understanding of the site, project information provided to us
and data obtained in our exploration. The general subsurface conditions utilized in our evaluation
have been based on interpolation of subsurface data between borings.

EXECUTIVE SUMMARY
From July 14 to August 6, 1994, TARGET Environmental Se1vices, Inc. (TARGE1)
conducted a soil gas survev and subsequent soil and groundwater sampling at the Conoco Slol'e
#33047 on Raleigh Street in Rocky Mount, North Carolina. A total of 23 soil gas samples were
manually collected from a depth of 4 feet. Direct-push, multiple-depth soil and groundwater
sample collection was then guided by the results of the soil gas data and performed using a van-
mounted hydraulic probe. The samples were analyzed on a gas chromatograph equipped with
a flame ionization detector (GC/FID) for petroleum hydrocarbons. The objective of the survey
was to determine the identity and concentrations of volatile petroleum hydrocarbons within the
subsurface.
Mapped analysis results indicate that there are high concentrations of petroleum
hydrocarbons east of the pump islands and moderately low concentrations extending northwest
from this location for 75 feet along East Grand Avenue. Moderate concentrations of petroleum
hydrocarbons were also observed on the east side of the gasoline UST area with moderately low
concentrations extending southeast toward North Raleigh Street. In the same areas, individual
analyte concentrations were observed at proportions of Total FlO Volatiles concentrations which
suggest gasoline contamination.

Introduction
Law En vi ron mental ( L~w) contracted TARGET Envinmmental Setvices, Inc. (TARGET) to
perform a soil gas survev and subsequent soil and groundwater sampling at the Conoco Stol'e
#3304 7 on Raleigh Street in Rocky Mount, North Carolina. The site is an operating gas station
and convenience store with associated gasoline and kerosene underground storage tank (UST)
systems. The objective of the survey was to determine the identity and concentrations of volatile
petroleum hydrocarbons within the subsurface.
The soil gas survey was designed by TARGET upon arrival to cover the site wtth regard to
potential sources of petroleum hydrocarbons within the subsurface. Samples were to be collected
at a depth of 4 feet. Subsequent soil and groundwater sampling locations and depths were
determined by LAW using soil gas analysis results. The field phase of the survey and follow-up
sampling was conducted from July 14 to August 6, 1994.
Sample Collection and Analvsis
Soil gas samples were collected at a total of 23 locations at the site, as shown in Figure I.
These soil gas samples were collected at the proposed depth of 4 feet. After soil gas sample
analysis, subsequent sampling included 30 soil samples and 12 groundwater samples. A detailed
explanation of the sampling procedures is provided in Appendix A.
All of the samples collected during the field phase of the survey were analyzed according
to EPA Method 8020 (modified) on a gas chromatograph equipped with a flame ionization
detector (GC/FID), and using direct injection. Analytes selected for standardization were:

TARGET Project HLC4
These compounds were chosen because of their utility in evaluating the presence of petroleum
I products such as fuels, lubricating oils, and non-halogenated solvents. An explanation of the
laboratory procedures is provided in Appendix B.
I The tabulated results of the laboratory analysis of the soil gas samples are reported in
I micrograms per liter (11g/l) in Table I. Although "micrograms per liter" is equivalent to "parts
I
per billion (v/v)" in water analyses, they are not equivalent in gas analyses, due to the difference
in the mass of equal volumes of water and gas matrices. The xylenes concentrations reported
I' in the data table are the sum of the m-and p-xylene and the o-xylene concentrations for each
I sample.
Soil and groundwater samples were submitted to Law on site for independent laboratory
I analysis.
I Qualitv Assurance/Qualitv Control (QA/Qq Evaluation
I Soil Gas Field QA/QC Samples
I Field control samples were collected at the beginning and end of each day's field activities
and after every twentieth soil gas sample. These QA/QC samples were obtained by filtering
I ambient air through a dust and organic vapor filter cartridge and encapsulating as described in
I the "Field Procedures" in Appendix A. The laboratory results are reported in Table I.
Concentrations of all analytes were below the reporting limit in all field control samples.

TARGET Project MLC4
Soil :md Groundwate•· Field QA/QC Samples
Field control samples were collected at the beginning and end of each day's field activities.
These QA/QC samples were obtained by rinsing distilled water through the decontaminated bailer
or sampling tube into sample vials. These samples were submitted along with the others as
described in the "Field Procedures" in Appendix A.
Laborato1v QA/QC Samples
To document analytical repeatability, a duplicate analysis was performed on every tenth field
sample. A laboratory blank of nitrogen gas was also analyzed after the tenth field sample. The
results of these analyses are reported in Table I. The duplicate analyses were within acceptable
limits. Concentrations of all analytes were below the reporting limit in all laboratory blanks.
Results
In order to provide graphic presentation of the results, Total FID Volatiles concentrations in
Table I have been mapped and contoured to produce Figure 2. Dashed contours are used where
patterns are extrapolated into areas of less complete data, or as auxiliary contours. Map sample
points with no data shown indicate that the analyte concentrations in the sample were below the
reporting limit. An explanation of the terminology used in this report is provided in Appendix
C.
Total FID Volatiles (Figure 2) were observed at a high concentration in Sample 4-11, which
was collected east of the pump islands. Moderately low concentrations were observed for 75 feet
northwest of Sample 4-11 along East Grand Avenue. Moderate Total FID Volatiles
concentrations were sampled on the east side of the gasoline UST area, and moderately low
concentrations extending southeast of this area towards North Raleigh Street were also observed.

APPENDIX A
FIELD PROCEDURES
Soil Gas
To·collect the samples a 112 inch hole was produced to a depth of approximately 4 feet by
using a drive rod. Where pavement was present, a rotary hammer was employed for penetration
:ior to using the drive rod. The entire sampling system was purged with ambient air drawn
through an organic vapor filter cartridge, and a stainless steel probe was inserted to the full depth
of the hole and sealed off from the atmosphere. A sample of in-situ soil gas was then withdrawn
through the probe and used to purge atmospheric air from the sampling system. A second sample
of soil gas was withdrawn through the probe and encapsulated in a pre-evacuated glass vial at
two atmospheres of pressure (IS psi g). The self-sealing vial was detached from the sampling
system, packaged, labeled, and stored for laboratory analysis.
Prior to the day's field activities all sampling equipment, slide hammer rods and probes were
decontaminated by washing with soapy water and rinsing thoroughly. Internal surfaces were
flushed dry using pre-purified nitrogen or filtered ambient air, and external surfaces were wiped
clean using clean paper towels.
Soil
To collect the samples, a van-mounted hydraulic probe was used to advance a 12" long 1-
5/8" OD steel sampling tube (equipped with an acetate liner and a piston stop tip) attached to
connected 3-foot sections of 1-3/8" OD threaded steel casing (EW rod) down to the sampling
depth. An electric hammer drill was used to penetrate pavement where necessary. The piston
stop was then released and the pipe driven an additional foot, allowing soil to enter the sample
tube. The sampling tube was retrieved and the liner removed from the casing·. The sample was
relinquished in the liner to the client for analysis by an independent laboratory. The sampling

To collect the samples a the hydraulic probe was used to advance E\V rod to the sampling
depth. An electric hammer drill was used to penetrate pavement where necessary. Where
borehole collapse was not a problem, the steel casing was removed and a 5-foot section of I"
diameter slotted PVC pipe connected to one or more 5-foot sections of PVC riser pipe was
inserted to the full depth of the hole. The pipe was allowed to sit for a period of time to allow
groundwater to fill the pipe. Where borehole collapse was a problem, once the steel casing was
in place, groundwater was allowed to fill the pipe. With either method, a water level sensor was
used to detect the surface of the groundwater table and to ensure that a sufficient amount of water
was present to complete a sample. The water level sensor was removed and a 21" long by 7/16"
0.0. stainless steel bailer was used to collect the sample. Samples were placed in 40 ml, teflon
septum-sealed glass vials and acidified to pH 2 using a 50% hydrochloric acid solution, sealed,
labeled and relinquished to the client for independent analysis.
Prior to the day's field activities and after collection of each sample, the steel casing and the
bailer apparatus were decontaminated by washing with Alconox (a biodegradable, laboratory
grade detergent), rinsing with distilled water and drying with filtered ambient air to ensure
discrete sampling. New PVC was used for each sample.
APPENDIX B
LABORATORY PROCEDURES
The analytical equipment was calibrated using a 3-point instrument-response curve and
injection of known concentrations of the target analytes. Retention times of the standards were
used to identify the peaks in the chromatograms of the field samples, and their response factors
were used to calculate the analyte concentrations.
Total FID Volatiles values were generated by summing the areas of all integrated
chromatogram peaks and calculated using the instrument response factor for toluene. Injection
peaks, which also contain the light hydrocarbon methane, were excluded to avoid the skewing
of Total FID Volatiles values due to injection disturbances and biogenic methane. For samples
with low hydrocarbon concentrations, the calculated Total FID Volatiles concentration is
occasionally lower than the sum of the individual analytes. This is because the response factor
used for the Total FID Volatiles calculation is a constant, whereas the individual analyte response
factors are compound specific. It is important to understand that the Total FID Volatiles levels
reported are relative, not absolute, values.

APPENDIX C
DETECfABILITY & TERMINOLOGY
Detectabilitv
The soil gas survey data presented in this report are the result of precise sampling and
measurement of contaminant concentrations in the vadose zone. Analyte detection at a particular
location is representative of vapor, dissolved, and/or liquid phase contamination at that location.
The presence of detectable levels of target analytes in the vadose zone is dependent upon several
factors, including the presence of vapor-phase hydrocarbons or dissolved or liquid concentrations
adequate to facilitate volatilization into the unsaturated zone.
Teominology
In order to prevent misunderstanding of certain terms used in TARGETs reports, the
following clarifications are offered:
Analyte refers to any of the hydrocarbons standardized for quantification in the chromatographic
analysis.
Anomaly refers to an area where hydrocarbons were measured in excess of what would normally
be considered "natural" or "background" levels.
Elevated and significant are used to describe concentrations of analytes which indicate the
existence of a potential problem in the soil or ground water.
Featul'e is used in reference to a discernible pattern in the contoured data. It denotes a contour
form rather than a definite or separate chemical occurrence.
Indicates is used when evidence dictates a unique conclusion. Suggests is used when several
explanations of certain evidence are possible, but one in particular seems more likely. As
a result, "indicates" carries a higher degree of confidence in a conclusion than does
"suggests."
APPENDIX C
Occun-ence is used to indicate an area where chemical compounds are present in sufficient
concentrations to be detected by the analysis of soil vapors. The term is not indicative of
any speciftc mode of occurrence (vapor, dissolved, etc.), and does not necessarily indicate
or suggest the presence of "free product" or "phase-separated hydrocarbons."
Repo1ting Limit refers to the minimum concentration reported for each analyte.
· 'adose zone represents the unsaturated zone between the ground water table and the ground
surface.
The terms "low", "moderate" and "high" levels, when applied to Total flO Volatile
petroleum hydrocarbons, are relative terms based on TARGETs analysis of thousands of soil gas
samples from hundreds of sites. Less than I 00 Jlg/1 can be considered very low. Levels between
0 and I 000 Jlg/1 can be considered typical "background" levels often observed at fuel handling
facilities. "Moderate" levels include concentrations in the range of 25,000 to 50,000 Jlg/1. Levels
greater than I 00,000 Jlg/1 are deemed "high", while those greater than 750,000 11gll are
considered to be very high.
