AECOM Technical Services of North Carolina, Inc., (AECOM) has completed the Preliminary
Site Assessment conducted at the above -referenced property. The work was performed in
accordance with the Technical and Cost proposal dated February 3, 2010, and the North Carolina
Department of Transportation's (NCDOT's) Notice to Proceed dated February 8, 2010.
Activities associated with the assessment consisted of conducting a geophysical investigation,
collecting soil samples for laboratory analysis, and reviewing applicable North Carolina
Department of Environment and Natural Resources (NCDENR) records. The purpose of this
report is to document the field activities, present the laboratory analyses, and provide
recommendations regarding the property.
Location and Description
The Dimtrios Skotidas Property (Parcel #69) is located at 4930 Davidson Highway (NC'73) in
Concord, Cabarrus County, North Carolina. The property is situated on the north side of
Davidson Highway at the intersection of NC 73 and Trinity Church Road (Figure 1). Based on
information supplied by the NCDOT and the site visit, AECOM understands that the site is an
active gas station/convenience store (Circle K) where four known underground storage tanks
(USTs) are present. These USTs include three 10,000-gallon gasoline tanks and one 10,000-
gallon diesel fuel tank. The structure on the property consists of one block building with an
asphalt parking lot in front and canopied pump islands. The USTs are located on the west side of
the building (Figure 2). The NCDOT has advised that the right-of-way/easement will not affect
the buildings or tanks (Figure 2). Because of the proximity of the pump islands, the NCDOT
requested a Preliminary Site Assessment. The scope of work as defined in the Request for
Technical and Cost Proposal was to evaluate the site with respect to the presence of known and

unknown USTs and assess where contamination exists on the property. An estimate of the
quantity of impacted soil was to be provided.
AECOM reviewed the on-line NCDENR Incident Management database and no Incident
Number has been assigned to the property. AECOM also examined the UST registration
database to obtain UST ownership information. According to the database, the USTs on the
property are operated under Facility Number 0-035360. The operator and owner of the tanks are
listed as follows:

Geophysical Survey
Prior to AECOM's mobilization to the site, Pyramid Environmental conducted a geophysical
survey as part of this project to evaluate if USTs were present on the proposed right-of-
way/easement. The geophysical survey consisted of an electromagnetic survey using a Geonics
EM61 time -domain electromagnetic induction meter to locate buried metallic objects,
specifically USTs. A survey grid was laid out at the property with the X-axis oriented
approximately parallel to NC 73 and the Y-axis oriented approximately perpendicular to NC 73.
The grid was located to cover the accessible portions of the proposed right-of-way. The survey
lines were spaced 5 feet apart. Magnetic data was collected continuously along each survey line
with a data logger. After collection, the data was reviewed in the field with graphical computer
software. Following the electromagnetic survey, a ground penetrating radar (GPR) survey was
conducted to further evaluate any significant metallic anomalies if such a survey was considered
necessary.
Access was available to all areas of the proposed rigbt-of-way/easement on the property and
several anomalies were detected with the geophysical survey. All of these anomalies were
attributed to buried utility lines or conduits, or vehicles. The survey concluded that no metallic
USTs were present on the right-of-way/easement. A detailed report of findings and
interpretations is presented in Attachment A.

Site Assessment Activities
On March 8, 2010, AECOM mobilized to the site to conduct a Geoprobe® direct push
investigation to evaluate soil conditions within the proposed right-of-way/easement. Continuous
sampling using direct push technology (Probe Technology of Concord, North Carolina) resulted
in generally good recovery of soil samples from the direct -push holes. Soil samples were
collected and contained in 4-foot long acetate sleeves inside the direct push sampler. Each of
these sleeves was divided into 2-foot long sections for soil sample screening. Each 2-foot interval
was placed in a resealable plastic bag and the bag was set aside for a sufficient amount of time to
allow volatilization of organic compounds from the soil to the bag headspace. The probe of a
flame ionization detector/photo ionization detector (FID/PID) was inserted into the bag and the
reading was recorded. After terminating the sample hole, the soil sample from the depth interval
with the highest FID/PID reading was submitted for analysis to Prism Laboratories in Charlotte,
North Carolina, using standard chain -of -custody procedures. The laboratory analyzed the soil
samples for total petroleum hydrocarbons (TPH) in the diesel range organics (DRO) and gasoline
range organics (GRO).
Six direct -push holes (DS-1 through DS-6) were advanced within the proposed right-of-
way/easement to a depth of 15 feet as shown in Figure 2 and Attachment B. The borings were
located to evaluate the entire right-of-way/easement on the property (Attachment Q. The
lithology encountered by the direct -push samples generally was consistent throughout the site.
The ground surface was covered with about 2 to 3 inches of asphalt/gravel or topsoil. Below the
surface to a depth of about 8 feet was a medium to reddish brown silt/clay. Underlying this
stratum was a saprolite consisting of mottled medium brown, reddish brown, and black silt/sand.
No bedrock was encountered in any of the borings. The "Geologic Map of North Carolina"
dated 1985 indicates that the site is underlain by a metamorphosed quartz diorite. The saprolite
observed at the site is consistent with this parent rock. All the borings were terminated at a depth
of 15 feet. No groundwater was observed in any of the borings. Based on field screening, soil
samples were submitted for laboratory analyses, which are summarized in Table 1. Following
the completion of each boring, it was backfilled in accordance with 15A NCAC 2C.
Analytical Results
Based on the laboratory reports, summarized in Table 1 and presented in Attachment D,
petroleum hydrocarbon compounds identified as DRO were detected in three of the six soil
samples collected from the site (Figure 3). The soil samples from borings DS-1, DS-2, and DS-3
contained GRO concentrations above the method quantitation limit. According to the North
Carolina Underground Storage Tank Section's Underground Storage Tank Closure Policy dated
August 24, 1998, the action level for TPH analyses is 10 milligrams per kilogram (mg/kg) for
both gasoline and diesel fuel. However, that agency's "Guidelines for Assessment and
Corrective Action," dated December 2008, does not allow for use of TPH analyses for
confirmation of the extent of petroleum contamination or its cleanup. As a result, while TPH
concentrations are no longer applicable in determining if soil contamination is present, this
A=COM

Mr. Ethan Caldwell

analysis is a legitimate screening tool. Based on the TPH action level for UST closures, the
assumed action level for this report is 10 mg/kg. The DRO concentrations in the soil samples
from borings DS-1 (16 mg/kg) and DS-2 (18 mg/kg) were present at concentrations above the 10
mg/kg assumed action level.
Conclusions and Recommendations
A Preliminary Site Assessment was conducted to evaluate the Dimitrios Skotidas Property
(Parcel #69) located at 4930 Davidson Highway in Concord, Cabarrus County, North Carolina.
Six soil borings were advanced to evaluate the soil conditions throughout the site right-of-way.
The laboratory reports of the soil samples from these borings suggest that DRO concentrations
were present above the assumed action level in two of the six soil samples analyzed.
To evaluate the volume of soil requiring possible remediation, the soil samples with TPH
concentrations above 10 mg/kg were considered. The analytical results of the soil samples
suggest that the soil from borings DS-1 (16 mg/kg) and DS-2 (18 mg/kg) contained TPH
concentrations identified as DRO above the assumed action level. A review of the field
screening readings (Table 1) suggests that the thickness of the potentially contaminated soil is
about 2 feet. After estimating the potential contamination geometry using field observations and
experience with similar sites and geology, AECOM measured the affected area by using CADD
software, which indicated a total area of about 3,775 ftZ. Based on a 2-foot contamination
thickness, this calculates to a volume of 279 cubic yards. This volume is estimated from TPH
analytical data, which are no longer valid for remediation of sites reported after January 2, 1998.
After this date, MADEP EPH/VPH and EPA Method 8260/8270 analyses will likely be required
to confirm cleanup. However, these analyses do not correlate exactly with TPH data and, as a
result, the actual volume of contaminated soil may be higher or lower.
AECOM appreciates the opportunity to work with the NCDOT on this project. Because
compounds were detected above the assumed action levels in the soil samples, AECOM
recommends that a copy of this report be submitted to the Division of Waste Management, UST
Section, in the Mooresville Regional Office. If you have any questions, please contact me at

1.0 INTRODUCTION
Pyramid Environmental conducted geophysical investigations for AECOM Environment across the
proposed Right -of -Way (ROW) portion of the Dimitrios Skotidas property (Parcel 69) located at the
intersection of Davidson Highway (NC-73) and Trinity Church Road (NC-1622) in Concord, North
Carolina. The geophysical surveyed portion of the property consists of grass and asphalt areas along
the southern third of the property. The site consists of an active Union 761Circle-K gas station/store
and the geophysical survey area has a maximum length and width of 345 feet and 80 feet,
respectively.
The geophysical investigation was conducted on February 20 and 23, 2010 to determine if unknown,
metallic underground storage tanks (USTs) were present beneath the proposed ROW area. AECOM
Environment representative Mr. Michael Branson, PG identified the geophysical survey area to
Pyramid Environmental personnel and provided site maps showing the boundaries of the proposed
survey area prior to conducting the investigation. Photographs of the geophysical equipment used in
this investigation and the geophysical survey area at the Dimitrios Skotidas property (Parcel 69) are
shown in Figure 1.
WIl"J � �13 WV 0 111)1l] 0111%_
Prior to conducting the geophysical investigation, a 10-foot by 20-foot survey grid was established
across the geophysical survey area using measuring tapes, pin flags and water -based marking paint.
These grid marks were used as X-Y coordinates for location control when collecting the geophysical
data and establishing base maps for the geophysical results.
The geophysical investigation consisted of electromagnetic (EM) induction -metal detection surveys
using a Geonics EM61-MKl metal detection instrument. According to the instrument specifications,
the EM61 can detect a metal drum down to a maximum depth of approximately 8 feet. All of the
EM61 data were digitally collected on February 20, 2010 at 0.8 foot intervals along easterly -
westerly, parallel survey lines spaced five feet apart. All of the data were downloaded to a computer
Dimitrios Skotidas Property (Parcel 69) - Geophysical Report 03118110
Pyramid Environmental & Engineering, P.C. 1

and reviewed in the office using the Geonics DAT61 W and Surfer for Windows Version 7.0
software programs
GPR surveys were conducted on February 20, 2010 across selected EM61 differential anomalies and
a small portion of the pump island area. GPR data were collected using a Geophysical Survey
Systems SIR-2000 unit equipped with a 400 MHz antenna. Data were digitally collected in a
continuous mode along X-axis and/or Y-axis survey lines, spaced 2.5 to 5.0 feet apart using a
vertical scan of 512 samples, at a rate of 48 scans per second. A 70 MHz high pass filter and an 800
MHz low pass filter were used during data acquisition with the 400 MHz antenna. GPR data were
collected down to a maximum depth of approximately 5 feet, based on an estimated two-way travel
time of 8 nanoseconds per foot. All of the GPR data were downloaded to a field computer and
reviewed in the field and office using Radprint software.
Contour plots of the EM61 bottom coil and differential results are presented in Figures 2 and 3,
respectively. The bottom coil results represent the most sensitive component of the EM61 instrument
and detect metal objects regardless of size. The bottom coil response can be used to delineate metal
conduits or utility lines, small, isolated metal objects, and areas containing insignificant metal
debris. The differential results are obtained from the difference between the top and bottom coils of
the EM61 instrument. The differential results focus on the larger metal objects such as drums and
USTs and ignore the smaller insignificant metal objects.
Preliminary geophysical results obtained from Parcel 69 were reported to Mr. Branson during the
week of March 1, 2010.
3.0 DISCUSSION OF RESULTS
The linear, EM61 bottom coil anomalies intersecting grid coordinates X=160 Y=95 and X=260
Y=115 are probably in response to a buried water line and conduit/line, respectively. GPR data
suggest the linear EM61 anomaly intersecting grid coordinates X=100 Y=95 is in response to a wide
diameter (1 to 2 feet wide) metallic utility line buried approximately 3.5 feet below surface. The

high amplitude, linear, bottom coil anomaly intersecting grid coordinates X=370 Y=95 is probably
in response to the metallic culvert that runs across the entrance road.
I
GPR data suggest the high amplitude EM61 differential anomaly centered near grid X=246 Y=145 is
i
in response to the pump island and steel reinforced concrete. The remaining EM61 anomalies are
probably in response to known surface objects or buried utility -related objects.
The geophysical investigation suggests that the surveyed portion of Parcel 69 (proposed ROW area)
does not contain unknown, metallic USTs.
4.0 SUMMARY & CONCLUSIONS
Our evaluation of the EM61 & GPR data acquired across the southern portion (proposed ROW area)
of the Dimitrios Skotidas property (Parcel 69) located at the intersection of Davidson Highway (NC-
73) and Trinity Church Road (NC-1622) in Concord, North Carolina, provides the following
summary and conclusions:
The EM61 and GPR surveys provided reliable results for the detection of metallic USTs
within the surveyed portion of the site.
The linear, EM61 bottom coil anomalies intersecting grid coordinates X=160 Y=95 and
X=260 Y=115 are probably in response to a buried water line and conduit/line, respectively
GPR data suggest the linear EM61 anomaly intersecting grid coordinates X=100 Y=95 is in
response to a wide diameter (1 to 2 feet wide) metallic utility line buried approximately 3.5
feet below surface.
• The remaining EM61 anomalies are probably in response to known surface objects or buried
utility -related objects. The geophysical investigation suggests that the surveyed -portion of
Parcel 69 (proposed ROW area) does not contain unknown, metallic USTs

5.0 LIMITATIONS
EM61 and GPR surveys have been performed and this report prepared for AECOM Environment in
accordance with generally accepted guidelines for EM61 and GPR surveys. It is generally
recognized that the results of the EM61 and GPR are non -unique and may not represent actual
subsurface conditions. The EM61 and GPR results obtained for this project have not conclusively
determine that the surveyed portion of the site does not contain buried metallic USTs, but that none
were detected.
