Introduction
Ram Leather Care is an inactive dry cleaning facility which operated from 1977 to
1993. The ten-acre parcel is surrounded by residential property. Several
environmental sampling investigations have documented that soil and groundwater
on the property are contaminated with chlorinated solvents commonly used in dry
cleaning operations. Additionally, low concentrations of these chemicals have been
detected in several private wells on nearby properties. At the request of the U.S.
Environmental Protection Agency (EPA), CDM Federal Programs Corporation
(CDM) investigated fractures in the bedrock between these private wells and the Ram
Leather facility. Four wells were selected to perform borehole geophysics for this
purpose. They are the Beaver well (PW-0022), on-site well (DW-0011), Segrest well
(PW-0011), and the State well (State well). This report documents the findings of the
investigation conducted in August 2002.

Section 2
Site Background
2.1 Geology
The soils at the site are classified as part of the Georgeville unit, characterized by a
silty clay loam. The surface layer is a yellowish red silty clay loam, approximately
5 inches thick. Below this is about 4 feet of acidic subsoil, the upper part of which is a
red silty clay. The lower part is a red silty clay loam. Under the subsoil is silt loam to
approximately 9 feet below land surface (bis). Depth to bedrock is about 42 feet bis
(Tingle 1991).
The site is located in the western edge of the Carolina Slate Belt of North Carolina.
Classified as phyllites, these rocks are very fine in texture. This metavolcanic rock is
characterized as interbedded felsic to mafic tuffs and flowrock. The residuum from
the fine grained slate forms the Georgeville series subsoil mentioned above (USGS
1980).
Rock units in the area have undergone periods of deformation that have produced
folding and fracture planes in rock, as well as brittle zones where the rock is crushed,
sheared, or faulted in some manner. As these rock types become weathered, soil
profiles develop that are characteristic of the original rock (saprolite). The rocks have
been fractured during metamorphic phases and, in some cases, the fractures have
been resealed by quartz. As rock weathers, these quartz fillings are retained in the
soil indicating that fractures existed in the rock. In addition, remnant fractures can be
seen in the soil profile without quartz infilling as indicated by the presence of iron
staining along the fracture plane. The iron staining is a result of groundwater
leaching iron from the surrounding material. As groundwater travels along a
fracture plane, the iron is redeposited along the plane.
2.2 Hydrogeology
Regionally, the water bearing units that underlie the site represent an aquifer system
consisting of metamorphosed and fractured phyllite rocks of varying proportions and
thicknesses. The aquifer system underlying the site generally consists of the
saprolite/ partially weathered rock aquifer and the underlying fractured bedrock
aquifer. In the site area, the groundwater is typically found in the saprolite aquifer
and the groundwater movement will generally mimic the overlying ground surface.
I
The depth to water is approximately 12 feet.
Groundwater movement is likely controlled by the presence of relict fractures present
in the saprolite, fractures in the partially weathered as well as competent bedrock,
and the steep dip of the bedrock units to the northwest. Given the complexity of the

bedrock at the site, the direction of groundwater movement depends primarily on
fractures, faults, bedding planes, etc. According to LeGrand and Mundorf£, most of
the natural flow in the bedrock system is probably confined to the upper 30 feet of
bedrock where fractures are concentrated, and the overlying transition zone which
apparently has the highest hydraulic conductivity of any part of the hydrogeologic
system (LeGrand and Mundorf£ 1952).

Section 3
Scope of Work
The investigation included downhole explorations using geophysical techniques,
groundwater sampling from discrete zones identified by the geophysical survey, and
a land survey to determine the horizontal and vertical coordinates of existing monitor
wells and potable wells.
3.1 Geophysical Survey
Advanced Geological Services of Malvern, Pennsylvania was contracted to provide a
geophysical characterization of fractures in bedrock at the Ram Leather site. The
fractures in the boreholes of four former drinking water wells were investigated. The
four potable water supply wells are identified as the on-site 510-foot well (DW-0011),
the Beaver well (PW-0022), the Segrest well (PW-0011), and the State well (state well)
shown in Figure 3-1.
The geophysical investigation consisted of the production of caliper logs, heat-pulse
flowmeter logs, fluid temperature logs, fluid conductivity ·logs, acoustic televiewer
logs, and optical televiewer logs. The caliper log showed the vertical variation in
borehole diameter. The flowmeter showed when a fracture was dry or saturated. The
fluid temperature and conductivity logs were used to distinguish between fracture
zones having unique temperature and conductivity. The acoustic televiewer log was
used to estimate fracture orientation. The optical televiewer showed the actual image
of the borehole wall.
Geophysical tools were decontaminated on-site after each exploration. The steps
included: (1) wash with Liquinox and water (soapy water was pumped through
pumps and tubing), (2) rinse twice with tap water, (3) rinse with de-ionized water
and (4) air-dry and transport to next well wrapped in plastic.
3.2 Pump Removal and Temporary Water Supply
Pump removal and replacement were needed at each well from which geophysical
data and groundwater samples were collected. Lee and Sims Drilling Services of
Belton, South Carolina was contracted to remove the submersible pump and
associated piping at each well. As the pump and piping were removed from the well,
they were laid down on plastic until they were stored and secured by the crew.
Pumps, piping, and plastic were placed in a secure location and identified clearly to
prevent installation of a pump in' the wrong well. The depth and type of pump
pulled from each well are shown in Table 3-1.

COM provided each resident whose well was taken out of service with a temporary
supply of potable water. Two residences were supplied with an alternate supply of
water: Beaver and Segrest. The Beaver residence was supplied with approximately
2,000 gallons of water. The Segrest residence was given approximately 500 gallons.
The water was dispensed to each household from two new 350-gallon polyethylene
tanks. The tanks were filled at the office facility of the drilling crew and a fire
hydrant located near the Ram Leather facility. The Subcontractor connei:ted the
water supply vessel to the house plumbing and reconnected and inserted the pump
when the geophysical data gathering and groundwater sampling was complete. After
the pumps were replaced, each well was disinfected according to North Carolina
Department of Natural Resources (NCDNR) Division of Groundwater Quality
protocols.
3.3 Discrete Zone Groundwater Sampling
Following the.acquisition of the geophysical data, an evaluation was made as to the
location of fracture zones within each well. After the fractures were identified, packer
testing was conducted to determine the production potential of each fracture zone.
To ensure discrete sampling, dual bladder inflatable packers were used to seal off the
6-inch diameter borehole and isolate the interval from groundwater above and below.
The interval between the packer seals was at least two feet. Pressure transducers
located above, below, and within the packer were not required. The materials of
construction were stainless steel for the metal portion and Viton for the inflatable
packer se_als. A low-flow variable speed submersible pump was placed between the
packers for purging and sampling of the fracture zones. Teflon tubing was used as
the discharge tubing from the pump.
The procedure at each well where discrete sampling was conducted included
(1) sealing off a 10-foot interval with the packer system, (2) pumping the sealed
interval dry, (3) allowing the interval to recharge and (4) using the water level tape to

determine if recharge occurred. If recharge occurred, a groundwater sample was
collected. If not, the packing apparatus was raised and the next interval was sealed
and investigated. Groundwater samples were collected from sealed intervals shown
in Table 3-2.
Packer testing and therefore discrete
zone groundwater sampling were not
performed at the State or Segrest wells
due to the presence of overhead power
lines. Groundwater samples were
collected from these wells, however. In
addition, one sample was obtained from
the Beaver well without aid of the
packer system. These samples were
collected by pumping with the original
submersible pump at each well. The
producing interval associated with these
samples was the entire open hole
section beneath the casing.

A total of 11 groundwater samples were collected to confirm or deny the presence of
chlorinated solvents in association with specific fracture zones. One sample was
collected from each of the State and Segrest wells. Seven samples were collected from
the on-site well and two were obtained from the Beaver well.
Each groundwater sample was collected into three 40-milliliter (mL) clear glass vials
and immediately stored with ice in a cooler. The samples were shipped by Federal
Express to a Contract Laboratory Program (CLP) laboratory the same day they were
collected. The samples were analyzed for the suite of volatile organic compounds
(VOCs) included in SW-846 Method 8260. A summary of the samples collected for
this investigation is shown below:

Horizontal and vertical coordinates were collected from the seven existing
groundwater monitoring wells and the four wells where geophysical measurements
were taken. Vertical measurements were taken from the highest side of the well
casing edge with the well cap off. In addition, the elevation of the ground surface
was measured next to each well. Vertical elevations of the monitoring wells are
accurate to within the nearest 0.01 feet. The horizontal data was provided in the state
plane coordinates and vertical data in the National Geodetic Vertical Datum (NGVD)
1929 datum.

Findings
4.1 Geophysical Survey
The objective of the geophysical evaluation was to delineate significant fracture zones
in the bedrock beneath the Ram Leather Care facility. This was done with
geophysical tools which indicated the vertical variation in borehole diameter,
groundwater temperature/ conductivity, groundwater movement, and fracture
orientation. A report prepared by a professional geophysicist detailing the results of
geophysical logging and associated field techniques is included as Appendix A.
Synthe~is of the data yielded significant water-bearing fracture zones as shown in
Table 4-1. These fracture zones, represented by numbers like N279,63, are shown in
Figure 4-1. This figure also shows well construction information, depth to water, and
total VOCs by zone.

The measured orientation of the fractures delineated by the investigation does not
portray a scenario explaining the migration of impacted groundwater from the
facility. A three dimensional plot of fracture planes associated with each well would
show significant discontinuity between the wells. Apparently, the fractures are not
correlative from well to well. In addition, the dip angle of the fractures is generally
high (>45 degrees) for the fracture sets. Laterally continuous fractures capable of
transmitting groundwater long distances would logically be oriented closer to the
hori2;ontal.

4.2 Groundwater Data
Section 4
Findings
The results of the groundwater sampling portion of the investigation were consistent
with previous findings. Tetrachloroethene (PCE), trichloroethene (TCE), and cis-1,2-
dichloroethene (cis-DCE) were the most significant contaminants, and the 510-foot
on-site well (DW-0011) is the most heavily contaminated. Contamination was noted
in each of the seven zones sampled in DW-001, with the zones at 262, 275, and 286 ft
bis the most heavily contaminated. The shallowest zone (128 ft bis) was the least
contaminated of the seven zones. Lower, but significant, concentrations of TCE, PCE,
and cis-DCE were observed in the off-site Segrest (PW-0011) and Beaver (PW-0022)
wells. Contamination found in the Segrest and Beaver wells could have occurred
through some or all the fracture zones located between 128 and 500 feet bis. No VOCs
were detected in the State well. Table 4-2 shows the detected analyte results of the
discrete zone groundwater sampling. The data as reported by the laboratory may be
found in Appendix B.
A map of groundwater contours is shown in Figure 4-2. According to the
groundwater contours, the direction of groundwater movement is generally toward
the east. However, topography south of the site slopes toward the southeast in the
direction of a surface water impoundment. Elevated concentrations of site related
VOCs observed in two wells (MW-2 and PW-0022) located southeast of the site
support at least some groundwater movement toward the southeast. Fractures may
be concentrated beneath stream beds and serve as preferential flowpaths for
groundwater.
Figure 4-3 shows the distribution of total VOCs in the vicinity of the Ram Leather
facility over the past ten years. As expected, the VOC concentrations are highest in
the area adjacent to the Ram Leather facility. The highest level was recorded in the
510 foot on-site well: 5,410 µg/L during the SESD investigation in 1999. The extent of
contamination to the west of the site appears to be defined as the total VOCs in MW-
1 D are comprised of chloroform and carbon disulfide. These compounds are
unrelated to the chlorinated solvents, or degradation products, of chemicals used at
the facility.
The extent of contamination to the northeast is largely defined. No VOCs were
detected in the State well which is northeast of the site, and the total VOCs shown at
MW-3O actually reflect the presence of acetone (7 µg/L), chloroform (1 µg/L), and
1,2-dichloroethane (1,2-DCA, 1 µg/L). Of these, only 1,2-DCA may be a site-related
compound.
The extent of contamination to the east reaches at least as far as MW-40 where a trace
concentration of PCE (0.8 µg/L) was detected by the on-site mobile laboratory. (See
COM' s Final Groundwater Investigation Report, August 31, 2001.) An evaluation of .

Findings
the groundwater contours suggests that this PCE was transported along the hydraulic
gradient in an easterly path toward MW-4O.
Site-related compounds were detected in groundwater samples collected from
MW-2O and PW-0022. It appears that bedrock slopes toward the southeast in the
direction of drainage features; therefore, the extent of contamination has not been
defined on this side of the facility.

Quality Assurance/Quality Control
5.1 Controlling Documents
■ Environmental Investigations Standard Operating Procedures and QualihJ Assurance
Manual (E/SOPQAM), U.S. EPA Region IV, Science and Ecosystems Support
Division (SESD), May 1996.
■ Draft Sampling and Analysis Plan and QualihJ Assurance Project Plan, COM Federal,
January 27, 2000.
The Sampling and Analysis Plan (SAP) specified and described all Quality
Assurance/ Quality Control (QA /QC), analytical data management, auditing and
reporting procedures for this investigation. By providing a framework for sample
collection, decontamination, field quality control, sample identification, chain of
custody and sample handling procedures, the controlling documents help ensure that
high quality data is collected and data comparability is enhanced.
5.2 Field Investigation
5.2.1 Groundwater Sampling
Execution of the groundwater sampling investigation followed procedures specified
in the SAP and EISOPQAM. Laboratory analyses were conducted in accordance with
EPA' s screening requirements, including QC requirements.
5.2.2 Field Quality Control Procedures
All data were collected as specified in the SAP. Field measurements were performed
in accordance with procedures specified in the SAP. All monitoring instruments were
calibrated either before each use, at the beginning of each field day, or at the
frequency specified for each procedure. All sampling equipment that came in contact
with sample media was decontaminated as specified in the SAP before each sample
was collected. All procedures regarding sample collection, chain-of-custody, and
submittal of samples were carried out as specified in the SAP. No field quality control
samples were prepared during this investigation.

5.3 Data Evaluation
5.3.1 Precision, Accuracy, Representativeness, Comparability,
Completeness
5.3.1.1 Precision
Precision is the evaluation of the reproducibility of a measurement. Precision is
estimated by the analysis of duplicate samples and the calculation of RPO or RSD.
This project involved the collection of laboratory duplicates. Where laboratory
duplicate criteria were not met, results were flagged "}"-estimated as appropriate.
5.3.1.2 Accuracy
Accuracy is a measure of the bias in a system. It is the degree of agreement of a
measurement with an accepted reference or true value. Accuracy for this project was
estimated from the analysis of QC samples whose true values are known (surrogate
or matrix spikes) and was expressed as percent recovery. For most analytes, surrogate
and matrix spike recovery criteria were met, indicating that the majority of the data
can be considered accurate. When recovery criteria were not met, results were flagged
"]"-estimated value.
5.3.1.3 Representativeness
Representativeness expresses the degree to which data can accura'tely and precisely
represent a characteristic of a population at a sampling point, process'condition, or
environmental condition.
5.3.1.4 Comparability
Comparability expresses the confidence with which one data set can be compared to
another. Representativeness and comparability are qualitative objectives which were
met by following standard operating procedures for sample collection and analysis.
5.3.1.5 Completeness
Completeness is the measure of the amount of valid data obtained from a
measurement system compared to the amount that was expected to be under current
normal conditions. The completeness of the data set for this investigation is based on
the number of valid data points. Table 5-1 shows the data set completeness.
A data completeness goal of 90% is routinely established by EPA RI/FS guidance
(October 1988) for laboratory data. Definitive data should generally be above 95% for
QC acceptance criteria due to the stringent requirements on the CLP program. All the

Subject: Results of Geophysical Logging
Ram Leather Site
Charlotte, North Carolina
Dear Mr. Profit:
--...;, .... ~ ADYN-r'I'-:, ~~ G&:OLOGICAL =------=-SERVIC&S -3 Mystic Lane
Malvern, PA 19355
[phone] (ph.)

Advanced Geological Services (AGC) is pleased to present this letter report that summarizes the
results of a borehole geophysical survey performed at the above referenced site on August 5th
through lQth, 2002. The survey was performed to help locate and characterize bedrock fractures,
which in turn would help characterize the local hydrogeologic conditions. To achieve this
objective, data were acquired using several sondes to produce optical and acoustic televiewer
images as well as natural gamma, caliper, fluid temperature, fluid conductivity, and heat pulse
flowmeter logs. The logging was performed in four wells: 1) PW-0022 (Beaver Well), 2) State
Well, 3) DW-0011, and 4) PW-0011 (Segrest We(l).
1.0 METHODOLOGY
1.1. DATA ACQUISITION SYSTEM
All geophysical logs were acquired using an RG-Micrologger2 digital logging system
manufactured by Robertson Geologging Ltd. (Robertson).
The borehole data were acquired using an RG-Mircologger2 digital logging system manufactured
by Robertson Geologging Ltd. This system boasts the latest technology and is considered the
most universal and powerful portable logging system in the world. Data from all sondes were
digitally recorded and were interpreted in the field using the integrated log and image processing
software as a quality control measure.
Each of the individual sondes will be briefly described below. All depths are reference from the
ground surface.
1.2. TEMPERATURE LOGS
Temperature logging provides a continuous record of the fluid temperature within a well. It can
indicate the movement of water through a borehole and the location of water producing or
accepting zones. If there is no flow in a borehole, the temperature will gradually increase as a
function of the geothermal gradient. The temperature log will show little change if rapid vertical
flow occurs. Slow vertical flow is common in wells that are completed through water-bearing
zones that have different hydraulic head. In this case, minor deflections are observed in an
otherwise linear log.

1.3. FLUID CONDUCTIVITY LOG
The fluid conductivity log provides fluid conductivity measurements in milliSeimen per
centimeter (mS/ cm). The sonde was calibrated by the manufacture prior to its arrival on site.
Data were acquired by logging in a downward direction after the well was allowed to equilibrate
overnight. Logging downward assured that the measurements were completed before the fluid
column was disturbed by the introduction of the sonde.
1.4. 3-ARM CALIPER LOG
The caliper log measures variations in borehole size as a function of depth in the well. The log
data enables (a) the detection of competent or fractured geologic units, (b) the location of
washouts or tight zones, (c) the optimal placement of well screen, sand, and bentonite, and (d) the
establishment of appropriate borehole correction factors to be applied to other well log curves.
Further, when run in combination with other logs, the caliper log may be an indicator of
lithologic makeup and degree of consolidation. The typical caliper response in a fractured,
weathered, or karstic unit is a relatively abrupt increase in borehole size.
1.5. NATURALGAMMARAYLOG
The natural gamma ray log is a passive instrument that measures the amount of naturally
occurring radioactivity from geologic units within the borehole. Commonly occurring radio-
elements include potassium, thorium, and uranium; the two former elements are predominant
within a common fine-grained rock sequence. The gamma ray instrument is also an excellent
lithologic indicator because fine-grained clays and shales contain a higher radioelement
concentration than limestones or sands. Gamma ray values are often used to assess the
percentage of clay materials (indurated or non-indurated) that are present within a formation by
utilizing empirically derived equations and sand-shale base line information. Finally, the
measurement of gamma ray emissions from a formation is a random process, thereby subjecting
the readings to natural statistical variations. The overall appearance of the gamma ray log is
similar, however small scale variations in the number of counts are noticeable.
1.6. HEAT PULSE FLOWMETER
The heat pulse flowmeter is used to measure vertical fluid movement within a borehole. The
data can be acquired under ambient or stressed conditions to infer the vertical distribution of
hydraulic conductivity in an aquifer. The data are usually collected under ambient conditions
after the well has had time to thermally equilibrate, or under designed stressed conditions such
as during the pumping or recovery phases of an aquifer test. Not all permeable intervals, such as
bedrock fractures, may produce vertical flow under ambient or un-stressed conditions if no
hydraulic head difference is present between permeable intervals.
1.7. ACOUSTIC BOREHOLE TELE VIEWER (BHTV) SONDE
The BHTV log provides a record of amplitude of high-frequency acoustic pulses reflected by the
borehole wall. Results from this sonde provide location and orientation information of features

such as fractures, lithologic contacts and cavities. A Robertson BHTV sonde was used to collect
the data. This particular sonde includes an orientation package to compensate for borehole
deviations and the rotation of the tool within the borehole while logging.
1.8. OPTICAL TELEVIEWER (OPTV) SONDE
The OPTV data were collected using a Robertson digital OPTV sonde. Like the BHTV data, the
OPTV data provides both location and orientation information about features such as fractures
and lithologic foliations. To collect OPTV data, the fluid within the borehole must be clear. The
resulting log provides an image of the borehole wall similar to what could be acquired by a
standard video log. Unlike a standard video log, the acquired image is digitized and properly
oriented with respect to borehole deviation and tool rotation, thereby allowing post processing of
the data to provide the feature strike and dip information. Unlike the BHTV images, the OJYfV
provides the optical view of the borehole wall making it possible visualize lithologic changes,
mineral veins and fracture characteristics.
2.0 RESULTS AND DISCUSSION
2.1. GENERAL
Pertinent sections geophysical logs are included as figures within this report. The complete logs
and images for each sonde type are provided in Attachment A. In addition, digital copies of the
logs and analysis reports are included on the CD provided with this report.
All depths are reference with respect to the ground surface.
2.2. PW-0022 (BEA VER WELL)
As shown in Figure 1, significant caliper variations were observed between 126 ft to 136 ft bgs
and 144 ft to 152 ft bgs. These anomalies were coincident with a gradual change in fluid
conductivity, which suggests ground water flow in these intervals. Similarly, caliper
irregularities were also observed from the bottom of casing (40 ft) and approximately 110 ft. An
increase in fluid conductivity values -which also suggests fluid flow -occurs at 53 ft to 75 ft, as
shown in Figure 2
These interpretations are corroborated by vertical flow within the borehole as indicated in the
heat pulse flow meter data shown in Figure 3. In addition, both OPTV and BHTV indicate the
presence of fracture zones coincident these locations. The BHTV and OPTV data are presented in
Attachment A. However, the high resolution of these data are not fully represented by hardcopy
output. ln order to view the detail required to see many of the fractures, the reader is urged to
view the digital provided on the enclosed CD.

The fracture dip nomenclature used in analysis is shown in Figure 4. Figure 5 is the fracture
analysis stereogram that presents the interpreted fractures in stereographic projection. During
analysis, small circles are interactively drawn around concentrations of similar fracture set
orientations. Mean-dips and fracture frequencies are calculated for each small-circle and
displayed as small bombsight symbols. Note that numeric results for the mean-dip are given as
strike and dip, the mean-dip azimuth is at +90• to the strike direction. The associated dispersion
is the maximum angle between the individual poles and the calculated mean-dip pole, in. , it is
not a statistical measure.

2.3. STATE WELL
Several zones indicating variations in borehole diameter were observed on the caliper logs
presented in Figure 7 through Figure 9. Large variations in conductivity were observed from the
water table to the base of casing (approximately 60 ft). This variation is attributed to the contrast
in fluid conditions between the relatively stagnant water in the casing to the more dynamic
conditions in the open hole. The conductivity values gradually equilibrate from below casing
downwards because of fluid mixing. This vertical flow within the borehole is also represented by
the heat pulse flow data shown in Figure 10. The flow values peak near 55 ft and appear to drop
off near the bottom of the· well.

Figure 12: Tadpole plot and frequency of fracture sets for State Well.
Several large variations in borehole diameter are observed in DW-0011 and suggest the presence
of fracture zones. These variations are observed on the caliper logs shown in Figure 13 and
Figure 14. Major variations in conductivity are observed from 470 ft to the end of the
conductivity run (approximately 490 ft), as shown in Figure 13. This increase in conductivity is
attributed to the inflow of more conductive water. Similarly, more subtle conductivity variations
are observed at the base of casing(~ 46 ft) and near the large caliper variation near 110 ft (Figure
14).
The heat pulse flow data (Figure 15) indicate the vertical flow in borehole fluids occurs from
approximately 200 ft to the end of log (approximately 500 ft). The vertical flow does not
necessarily indicate inflow of ground water throughout this zone, only that there appears to be
consistent vertical flow between zones near the bottom of the well and approximately 200 ft.

2.5. PW-0011 (SEGREST WELL)
Several large variations in borehole diameter are observed in PW-0011 and suggest the presence
of fracture zones (Figure 18 & Figure 19). Associated with the caliper variations near 70 ft is a
marked increase in fluid conductivity. The change in fluid conductivity suggests the occurrence
of ground water near this depth. Similarly, the fluid conductivity increase near 230 ft suggests
the same. The occurrence of ground water flow between 70 ft and 230 ft is corroborated by the
heat pulse flowmeter data shown in Figure 20.
Stereographic fracture analysis (Figure 21) indicates the presence of four major fracture
orientations: N132 67, N064 59, N220 39, and N310 60. The locations of these interpreted
fractures are shown in Figure 22. The N132 67 fracture set is observed at many depths within the
borehole, while N064 59 and N220 39 set appear near the bottom of the boring. The N310 60
facture set occurs near the top of the boring.

4.0 CLOSING
The data collection and interpretation methodologies used in this investigation are consistent
with standard practices applied to similar geophysical investigations. The correlation of
geophysical responses with probable subsurface features is based on the past results of similar
surveys although it is possible that some variation could exist at this site. Due to the indirect
nature of geophysical data, no guarantees can be made or are implied regarding the presence or
absence of additional features beyond those identified.
