SITE HISTORY AND CHARACTERIZATION
The site address is 719 East Main Street, Pilot Mountain, Surry County, North Carolina,
based on the Surry County GIS system. The site address was listed in previous reports as
708 E. Main Street. The former Needham Service Station (UST Database: Formerly
Needham’s Grocery) site previously operated as a gas station and is currently used as an
office building.Figure 1 indicates the site location and topography. A site plan is shown
as Figure 2. Site photographs are included in Appendix I.
On August 18, 1987, a release due to a leaking elbow joint in the product pipeline was
reported to the Surry County Fire Marshall. On October 22, 1991, three 4,000-gallon
gasoline USTs were removed from the site. Based on a Groundwater Investigation and
Remedial Action Plan by Engineering Tectonics (ET), dated July 22, 1988, nine
groundwater monitoring wells (MW-1, 2, 3, 4, 5, 6, 7, 8, 9) were installed at the site and
northeast of the site at 723 (Hurst Garage) and 733 52 Bypass located across Highway 52
Bypass from the subject site.
Between April 2004 and January 2005, Geological Resources, Inc. (GR) sampled the site
monitoring wells not containing free product and one water supply well (WSW-1). Free
product was noted in monitoring well MW-2 during the sampling events. Petroleum
constituent concentrations greater than the NCAC 2L groundwater quality Standards (2L
Standards) were detected in sampled collected from multiple monitoring wells.
Concentrations greater than the Gross Contaminant Levels (GCLs) were reported in
monitoring wells MW-6R, MW-7 and MW-8. Monitoring wells MW-1, MW-4 and
MW-6 were destroyed by a snowplow. MW-6R was installed in 2004 as a replacement
to MW-6. In August 2004, a mobile multiphase extraction (MMPE) event was conducted
on monitor wells MW-2 and MW-6R with 3,514 gallons of liquid removed. A total of 18
gallons of free product was recovered.
Between March 2006 and May 21, 2007, Terraine sampled the site monitoring wells not
containing free product and two water supply wells (WSW-1 and WSW-3). MW-11 was
installed on May 21, 2007. Free product was noted in MW-2, MW-3 and MW-6R during
the sampling event on May 24, 2007. MW-3 had measurable product only once since its
installation. Constituent concentrations greater than the 2L Standards were reported in
multiple monitoring wells and greater than the GCLs were reported for Benzene,
Ethylene dibromide (EDB) and 1, 2-Dichloroethane (1,2-DCA) in monitoring well MW-
7.
On November 20, 2008, Terraine conducted a monitoring event including 10 monitoring
wells (MW-1R, MW-2, MW-3, MW-5, MW-6R, MW-7, MW-8, MW-9, MW-10 and
MW-11) and one water supply well (WSW-1). Free product was observed in MW-6R at
a thickness of 0.14 feet. The lab results from the collected samples indicated petroleum
constituent concentrations greater than the 2L Standards in five monitoring wells (MW-
1R, MW-5, MW-8, MW-9, MW-11) with concentrations of Benzene, EDB and 1, 2-DCA
in MW-2, and Benzene in MW-7, greater than the corresponding GCLs.
On January 5 and 15, 2010, S&ME conducted a monitoring event including eight
monitoring wells (MW-1R, MW-3, MW-5, MW-7, MW-8, MW-9, MW-10, MW-11) and
Groundwater Monitoring Report – NCDENR Incident No.3510 S&ME Project No. 4305-15-047

one water supply well (WSW-1). Free product was observed in MW-2 (0.02 feet) and in
MW-6R (0.11 feet). The lab results from the collected samples indicated petroleum
constituent concentrations greater than the 2L Standard in four monitoring wells (MW-5,
MW-7, MW-9, and MW-11). A water sample was collected from water supply well
WSW-1 on January 15, 2010. No petroleum constituents were reported above the
laboratory reporting limits.
S&ME conducted one 8-hour aggressive fluid/vapor recovery (AFVR) event on October
15, 2010, using wells MW-2 and MW-6R. During the AFVR event, approximately 472
pounds of vapor phase hydrocarbons were removed, which corresponds to approximately
75 gallons of gasoline recovered.
On October 15 and 25, 2010, S&ME conducted a monitor well sampling event on
monitoring wells MW-2, MW-5, MW-6R, MW-7, MW-8, MW-9 and MW-11. Each
sample contained several constituent concentrations greater than the 2L Standards, with
the highest concentrations detected in monitor well MW-2. Concentrations in monitoring
wells MW-2, MW-5, MW-6R, MW-7, MW-8, MW-9 and MW-11 appeared to be
decreasing relative to the November 2008 sampling event.
S&ME conducted one 8-hour AFVR event on May 11, 2011, using monitoring wells
MW-2 and MW-6R. Prior to the AFVR event, no free product was measured in MW-2
or MW-6R. A total of 1,197 gallons of total fluids was removed, and an estimated total
of 1,177 pounds of vapor phase hydrocarbons (which corresponds to approximately 188
gallons of gasoline) was recovered from MW-2 and MW-6R.
On May 11 and 24, 2011, S&ME was on-site to measure the depth to water and free
product, and to collect groundwater samples from monitoring wells without free product.
Based on the top of casing elevations and depth to liquid, groundwater flow is generally
towards the north. Monitor wells MW-1R, MW-2, MW-5, MW-6R, MW-7, MW-8,
MW-9 and MW-11 contained several constituent concentrations greater than the
corresponding 2L Standards, with the highest concentrations detected in monitor well
MW-6R. Benzene was detected above the GCL in monitoring wells MW-2, MW-6R,
and MW-7. EDB was detected above the GCL in monitoring well MW-6R.
S&ME conducted one 8-hour AFVR event on January 4, 2012 using monitoring wells
MW-2 and MW-6R. Prior to the AFVR event, no free product was measured in MW-2
or MW-6R. A total of 855 gallons of total fluids was removed, and an estimated total of
16 pounds of vapor phase hydrocarbons (which corresponds to approximately 3 gallons
of gasoline) was recovered from MW-2 and MW-6R.
On February 22 and 23, 2012, S&ME was on-site to measure the depth to water and free
product, and to collect groundwater samples from monitoring wells without free product.
Monitoring wells MW-2, MW-5, MW-6R, MW-7, MW-8, MW-9 and MW-11 contained
several constituent concentrations greater than the corresponding 2L Standards, with the
highest concentrations detected in monitor well MW-6R. Benzene was detected above
the GCL in monitoring wells MW-2, MW-6R, and MW-7. EDB exceeded the GCL in
monitoring well MW-6R.

On September 19, 2012, S&ME collected groundwater samples from monitoring wells
without free product. Monitoring wells MW-2, MW-5, MW-6R, MW-7, MW-8, MW-9
and MW-11 contained several constituent concentrations greater than the corresponding
2L Standards, with the highest concentrations detected in monitor well MW-6R.
Benzene was detected above the GCL in monitoring wells MW-2, MW-6R, and MW-7.
EDB exceeded the GCL in monitoring well MW-6R.
S&ME completed a groundwater sampling event in April 2014 (Groundwater Monitoring
Report dated May 16, 2014). Dissolved petroleum concentrations were reported in the
site groundwater at concentrations greater than GCLs.
4.1 UST Owner and Operator Information
According to the NCDENR UST database, three USTs were formerly located at the site

CURRENT SITE ASSESSMENT INFORMATION
5.1 Soil Boring and Monitor Well Installation
On March 12, 2015, S&ME performed soil borings MW-12, MW-13 and MW-14. MW-
12 was performed at reported, former line leak location, MW-13 was performed in the
apparent downgradient position to the former UST basin, and MW-14 was performed at
the former dispenser. Figure 2 shows the locations of the soil borings. Each soil boring
was extended to approximately 44 feet to 46 feet below the ground surface. Soil samples
were collected at periodic intervals during the performance of each soil boring and
screened in the field with a photoionization meter (PID). PID readings at each soil boring
location measured greater than 15,000 parts per million (ppm) from near the ground
surface to the termination depth.
Soil samples at soil boring MW-12 were selected from the 10 feet, 20 feet and 30 feet
depth intervals for laboratory analysis. Soil samples at soil boring MW-14 were selected
from the 5 feet, 15 feet and 25 feet depth intervals for laboratory analysis. No soil
samples were selected from soil boring MW-13 for laboratory analysis. Each soil sample
was submitted to the laboratory for analysis of gasoline range total petroleum
hydrocarbons (TPH-GRO). Soil samples MW-12-10 and MW-14-5 were also analyzed
for volatile organic compounds by EPA Method 8260 and volatile petroleum
hydrocarbons (VPH) by the MADEP Method.
Each soil boring was extended to groundwater, and a 2-inch diameter monitor well was
installed in each soil boring. Each well was constructed of Schedule 40 PVC with a 15-
foot length of well screen set at the bottom of the borehole. The Well Completion
Reports and Non-residential Well Records for the newly-installed monitor wells are
included in Appendix I. Well construction details are summarized in Table 1.
5.2 Current Liquid Levels
On March 13, 2015, S&ME was on-site to gauge depth-to-water and collect groundwater
samples from monitoring wells MW-1R, MW-2, MW-3, MW-6R, MW-7, MW-11, MW-
12, MW-13 and MW-14.
S&ME personnel used an electronic water level indicator to measure the depth-to-
groundwater from the top of well casing. The depth-to-water measurements ranged from
25.63 feet below top of casing (BTOC) in monitoring well MW-3 to 42.14 feet BTOC in
monitoring well MW-7. The groundwater level measurements from the March 13, 2015,
sampling event are summarized in Table 1. The water level measurements were used to
prepare a groundwater elevation map (Figure 4).
Free product was encountered in monitor well MW-13. S&ME used an oil/water
interface probe to measure the free product thickness, which was measured at 0.64 feet.
5.3 Groundwater Monitoring Events
After measuring the depth-to-water, S&ME personnel purged monitoring wells MW-2,
MW-7, MW-9, MW-12 and MW-14, with dedicated disposable polyethylene bailer by
Groundwater Monitoring Report – NCDENR Incident No.3510 S&ME Project No. 4305-15-047
Needham Service Station, Pilot Mountain, Surry County NC July 10, 2015

evacuating at least three well volumes from each of the wells. The well sampling forms
are included in Appendix I.
S&ME misidentified monitor well MW-9 for MW-11. Monitor well MW-11 was recorded
on the sampling forms, chain-of-custody forms and laboratory report; however, the
reported data represents monitor well MW-9.
After completing the well purging and allowing groundwater to recover in the monitoring
wells, S&ME personnel collected a groundwater sample from each of the wells. The
groundwater samples were placed in laboratory-supplied containers, stored in a cooler with
ice, and shipped under chain-of-custodyprocedures to Pace Analytical Services, Inc. (Pace),
a North Carolina certified laboratoryfor laboratory analysis. The groundwater samples
were analyzed VOCs by EPA Method 6200B including methyl-tert-butyl ether (MTBE),
diisopropyl ether (IPE), and ethylene dibromide (EDB).
The collected water sample was placed in laboratory-supplied containers, stored in a cooler
with ice, and shipped under chain-of-custodyprocedures to Pace for laboratory analysis.
The groundwater samples were analyzed for VOCs byEPA Method 6200B including
MTBE, IPE, and EDB.
5.4 Summary of Soil and Groundwater Analytical Results
Soil analytical data is summarized in Table 3. As shown, TPH-GRO was reported in
samples collected from the 10 and 20 feet depth intervals at MW-12, and from the 5 and
15 feet depth interval at MW-14. TPH-GRO was not reported in the sample collected
from 30 feet at MW-12, or from 25 feet at MW-14.
Multiple petroleum constituents were reported in samples MW-12-10 and MW-14-5 at
concentrations greater than the soil-to-groundwater Maximum Soil Contaminant
Concentrations (MSCCs). Only C9-C18 Aliphatics was reported at a concentration
greater than the residential MSCC. No target analytes were reported at concentrations
greater than the industrial/commercial MSCCs.
Groundwater analytical data is tabulated in Table 4. Multiple compounds were reported
in the groundwater samples at concentrations exceeding the 2L Standards. Benzene was
reported in monitor wells MW-7 and MW-14 at concentrations exceeding the Gross
Contaminant Levels (GCLs). Ethylene dibromide (EDB) was reported in sample MW-14
at a concentration greater than the GCL. A constituent map illustrating the data from
Table 4 is included as Figure 3.Figures 5 and 6 illustrate the estimated extent of
benzene and methyl tert-butyl ether (MTBE) in the groundwater.
A copy of the laboratory analytical results and chain-of-custody form is included in
Appendix II.
5.5 Regional and Site Geology and Hydrology
5.5.1 Soil and Bedrock
According to the 1985 USGS Geologic Map of North Carolina, the site is located in
Sauratown Mountains Anticlinorium. Bedrock in this area is characterized as
Groundwater Monitoring Report – NCDENR Incident No.3510 S&ME Project No. 4305-15-047
Needham Service Station, Pilot Mountain, Surry County NC July 10, 2015
10
Metamorphosed Granitic Rock. Bedrock was encountered near the former UST basin
during previous assessment activity at depths ranging from approximately 45 feet to 55
feet; however, bedrock was not encountered at depths ranging from approximately 44
feet to 46 feet below ground surface by current soil borings performed to install monitor
wells MW-12, MW-13 and MW-14.
5.5.2 Hydrogeology
Based upon measurements collected on March 13, 2015, groundwater at the site generally
flows from the former UST basin location to the northeast with an approximate gradient
of 0.033 feet per foot, and from the former UST basin to the southeast with an
approximate gradient of 0.025 feet per foot.Figure 4 graphically depicts the
approximate groundwater flow at the site based upon the March 13, 2015, measurements.
5.6 Evaluation of Groundwater Assessment Information
5.6.1 Current Extent and Severity of Contamination
Based on the results of soil samples collected from monitor wells MW-12 and MW-14 on
March 12, 2015, petroleum constituents were reported in the soil at concentrations
exceeding soil-to-groundwater MSCCs and residential MSCCs but less than
industrial/commercial MSCCs. The extent of petroleum impacts in the soil has not been
defined. Soil vapor readings collected during the installation of monitor wells MW-12,
MW-13, and MW-14 suggest residual soil impacts are influencing groundwater quality.
The extent of impacted groundwater is unknown. Free product was measured in newly
installed monitor well MW-13 at a thickness of 0.64 feet. Benzene and EDB are present
in the groundwater at concentrations exceeding GCLs.
Historically, free product has been detected in monitor wells MW-6R and MW-2. The
intermittent detections reported in monitor well MW-2 are likely due to the installation of
the screened well interval below the water table.
5.6.2 Cleanup Levels Achieved
•Soil (Industrial/Commercial MSCCs)Yes
•Groundwater (GCLs)No
•Free Product No

CONCLUSIONS AND RECOMMENDATIONS
Three monitor wells were installed and soil samples were collected at the former
Needham Service Station UST site located at 719 E. Main Street in Pilot Mountain, Surry
County, North Carolina. After monitor well installation was completed, a groundwater
sampling event was performed to assess current petroleum impact to groundwater.
The findings at the site are as follows:
•The site qualifies as an Intermediate Risk site.
•No active water supply wells are reported within 1,000 feet of the source area.
Municipal water is available to the site and surrounding area.
•Field screening data collected during the installation of three new monitor wells at
the site documented volatile organic vapor concentrations in the soil column from
near the ground surface to the water table at concentrations greater than 10,000
parts per million.
•Laboratory analyses performed on soil samples collected during the installation of
monitor wells MW-12 and MW-14 documented the presence of petroleum
constituents in the soil at concentrations greater than the soil-to-groundwater
MSCCs and the residential MSCCs.
•Free product was measured at a thickness of 0.64 feet in newly installed monitor
well MW-13.
•Groundwater samples collected from monitor wells MW-2, MW-7, MW-9, MW-
12 and MW-14 contained multiple petroleum constituents at concentrations
greater than the corresponding 2L Standards.
•Benzene was reported in monitor wells MW-7 and MW-14 at concentrations
greater than GCLs.
•Ethylene dibromide was reported in monitor well MW-14 at a concentration
greater than the GCL.
•Groundwater flow appears to be divergent from the former UST basin, with flow
northeast of the source area to the northeast and southeast of the source area to the
southeast.
Based on the above, S&ME recommends the following:
1.Perform an MMPE event using on-site wells MW-13 and MW-14 to remove the
residual petroleum in the vadose zone and to reduce dissolved petroleum
concentrations in the groundwater. During the MMPE event, readings should be
collected from nearby monitor wells to measure for pressure differentials to assess
the potential for vapor extraction to be performed at the site.
2.Sample selected monitor wells in conjunction with MMPE events or on a semi-
annual schedule.
