Needham Service Station WR Project # 02172214.50 Annual Monitoring Report June 2021 3
SECTION B. EXECUTIVE SUMMARY
1. Summary of Activities Associated with Current TA
WithersRavenel, Inc. (WR) conducted a groundwater monitoring event at the Needham Service Station incident located at 719 East Main Street in Pilot Mountain, Surry County, North Carolina.
These activities were completed in association with TA-01, under NCDEQ Contract #N122019B. The scope of work for this project included the gauging and sampling of MW-2, MW-5, MW-6R, MW-7, MW-9, MW-11, MW-12, MW-13, and MW-14. WR was unable to locate MW-9 but did locate MW-8 and collected a groundwater sample from that well, I lieu of MW-9. LNAPL was
identified in MW-13 which was, therefore, not sampled. 2. Soil, Groundwater and LNAPL Assessment Information
Soils
The UST system was removed in October 1991. Soil borings advanced in the vicinity of the USTs during 1987 identified elevated TPH concentrations in soil. Soil assessment activities conducted during the installation of MW-12 and MW-14 identified several petroleum compounds between 5 and 10 feet below ground surface at concentrations that exceeded the Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs). C9-C18 Aliphatic hydrocarbons were
reported in MW-12 (10’) at a concentration that exceeded the Residential MSCC. TPH-GRO concentrations above the NCDEQ standard of 50 mg/kg extended to 20 feet bgs in the MW-12 boring.
Groundwater
Laboratory results for the groundwater samples obtained from MW-6R and MW-14 on April 23, 2021 revealed benzene at concentrations that exceeded the Gross Contamination Level (GCL). EDB was reported in MW-14 at a concentration that exceeded the GCL for the compound. Several additional compounds were reported at concentrations that exceeded their respective NCAC 2L Standards in monitoring wells MW-2, MW-5, MW-6R, MW-7, MW-8, MW-12, and MW-14.
LNAPL/Free Product LNAPL/Free Product was measured in MW-13 at a thickness of 1.18 feet in April 2021. LNAPL has been consistently measured in MW-13 since the well was installed in March 2015. LNAPL has historically been identified in MW-2 and MW-6R but not since January 2010.
3. Receptor Information According to historical reporting, municipal water is available to the local area. WR did not complete a receptor survey during the April 2021 monitoring event. Based on historical receptor
information (December 2008), WSW-4, an inactive supply well, is located within 500 feet of the subject property; WSW-2, an inactive supply well, is located between 500 feet and 1,000 feet of the subject property; while WSW-1 and WSW-2 are active water supply wells located between 1,000 feet and 1,500 feet of the subject property. The locations of both WSW-2 and WSW-4 are reportedly connected to the municipal water system.

Needham Service Station WR Project # 02172214.50 Annual Monitoring Report June 2021 4
One intermittent blue line tributary of Toms Creek was identified approximately 720-feet east northeast of the subject property. According to the SWAP Mapping Application, no wellhead protection areas are located within
1,500-feet of the subject property. According to the SWAP Mapping Application the subject property is located within the Stream Zone Inside Protection Area for the Town of Pilot Mountain (PWS ID: NC0286025).
4. Remediation Activities Along with the closure of the UST system, the following remedial activities have occurred:
• AFVR Events: October 2011, May 2011, and January 2012 recovered vapor as gasoline equivalent to 75 gallons, 188 gallons, and 3 gallons, respectively. An MMPE event performed during August 2012 using monitoring wells MW-2 and MW-6R recovered 87 gallons of gasoline as vapor.
• A hybrid air sparge/MMPE event performed during April 2019 using monitoring wells MW-2 (air sparge), and MW-6R, MW-13 and MW-14 (MMPE), recovered approximately 70 gallons of gasoline as vapor and 4,560 gallons of product/water mix, including approximately 92 gallons of gasoline as liquid.

5. Recommendations Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following if funding levels are sufficient:

• Targeted excavation to remove petroleum impacted soils.
• Surfactant Enhanced MMPE on MW-13 to abate LNAPL.
• Following abatement of LNAPL, emplacement of ISCO agent to reduce dissolved phase petroleum impacts to concentrations less than GCLs.
• Continue semi-annual monitoring of site monitoring wells.

Needham Service Station WR Project # 02172214.50 Annual Monitoring Report June 2021 8
The subject property is located at 709 East Main Street in Pilot Mountain, Surry County, NC. The property includes one story brick office building operated as J-N-R Auto, LLC (used car dealership).
Surface drainage through the area generally follows topography or is channeled through sub-surface stormwater structures or wet-weather ditches running parallel to primary and secondary roadways. 4. Information on Receptors/Potential Receptors
According to historical reporting, municipal water is available to the local area. WR did not complete a receptor survey during the April 2021 monitoring event. Based on historical receptor information (December 2008), WSW-4, an inactive supply well, is located within 500 feet of the subject property; WSW-2, an inactive supply well, is located between 500 feet and 1,000 feet of
the subject property; and WSW-1 and WSW-2 are active water supply wells located between 1,000 feet and 1,500 feet of the subject property. The locations of WSW-2 and WSW-4 are reportedly connected to the municipal water system. One intermittent blue line tributary of Toms Creek was identified approximately 720-feet east
northeast of the subject property. According to the SWAP Mapping Application, no wellhead protection areas are located within 1,500-feet of the subject property.
According to the SWAP Mapping Application the subject property is located within the Stream Zone Inside Protection Area for the Town of Pilot Mountain (PWS ID: NC0286025).

SECTION D. SITE GEOLOGY AND HYDROGEOLOGY According to the Geologic Map of North Carolina, dated 1985, the site is underlain by Proterozoic
to Cambrian metamorphosed granitic rocks. Bedrock was not encountered within 30.4 feet of the ground surface during installation of monitoring well MW-13. During prior assessment activities performed by others, bedrock was encountered by soil borings performed to install monitoring wells MW-2 and MW-3 at depths of 55 feet and 65 feet below ground surface, respectively. Monitoring well MW-2 was installed in unconsolidated material to the top of bedrock, but MW-3
was installed approximately 10 feet into bedrock [Cross-section A-A’, Groundwater Investigation, Engineering Tectonics, P.A. (July 1988)]. Based on the Soil Survey of Surry County, North Carolina, soils on the property are classified as Urban land (Ur). Urban land is described as altered by cutting, filling, grading and shaping so that
the original topography and drainage have been changed. Subsurface soil characterized during installation of monitoring wells MW-2 through MW-9 by others consisted of silt, sandy silt and silty fine sand overlying weathered rock. Subsurface soil characterized during installation of monitoring well MW-13 consisted of silty clay and clayey silt, underlain by silt.
Groundwater has historically been measured to be approximately 32 to 38 feet below ground surface on the subject property.

SECTION E. GROUNDWATER INVESTIGATION – APRIL 2021 On April 21, 2021, WR personnel mobilized to the subject property to perform groundwater
sampling activities at the facility in association with TA-01 under NCDEQ Contract # N122019B. The following paragraphs describe the sampling activities and associated laboratory analytical results. E.1. MONITORING WELL GAUGING AND SAMPLING
WR collected a groundwater samples from MW-2, MW-5, MW-6R, MW-7, MW-8, MW-11, MW-12, and MW-14 following purging. WR was unable to locate MW-9 but did locate MW-8 and collected a groundwater sample from the well, in lieu of MW-9. LNAPL was identified in MW-13 at a thickness of 1.18 feet and the well was, therefore, not sampled.
Groundwater elevations ranged from 33.05 feet below top of casing (BTOC) in MW-12 to 38.36 feet BTOC in monitoring well MW-7. Based on these elevations, groundwater flow direction appears to be towards the east-northeast. This groundwater flow direction corresponds with historical reporting.
Monitoring well information is included in Table B-9 and a groundwater contour map is included as Figure 3. E.2. LABORATORY RESULTS
Analytical results for the groundwater samples revealed the following:
• One or more VOC compounds were reported in each of the sampled monitoring wells at
concentrations that exceeded their respective NCAC 2L Standards.
o Tetrachloroethene (PCE), a non-petroleum related compound, was reported in MW-8 and MW-12 at a concentration that exceeded the NCAC 2L Standard.
• Benzene was reported in MW-6R and MW-14 at concentrations that exceeded the GCL.
• EDB was identified in MW-14 at a concentration that exceeded the GCL. The following changes in total VOCs concentrations were shown between the August 2020 and April 2021 sampling period:

Well ID Total VOCs (µg/L) Change August 2020 April 2021
MW-2* 227.13 2,892 +1173%
MW-6R 56,818 77,046 +35.6%
MW-7 3,665 3,275 -10.6%
MW-14 61,690 90,244 +46.3%
* - MW-2’s screen is submerged.

SECTION F. CONCLUSIONS & RECOMMENDATIONS This report documents the results of field activities conducted at the site for TA-01, which included
the sampling of site monitoring wells. Conclusions based on observations, analytical data and research relating to the release at the site combined with historical information include the following:
• Municipal water is available to the local area.
• Two active water supply wells have historically been identified between 1,000-feet and 1,500-feet from the subject property.
• No active water supply wells are reported to be located within 1,000-feet of the subject property.
• One intermittent tributary is located within 1,000-feet of the subject property.
• No wellhead protection areas are located within 1,500 ft of the site.
• LNAPL was measured at a thickness of 1.18 feet in MW-13.
• GCL exceedances were reported in MW-6R and MW-14.
• NCAC 2L exceedances were reported in all eight sampled monitoring wells.
• Based current and historical total VOC concentrations, dissolved phase impacts appear to be
increasing or remaining steady in the vicinity of MW-6R and MW-14 and decreasing in
downgradient offsite monitoring wells MW-7 and MW-8. Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following if funding levels are sufficient:

• Targeted excavation to remove petroleum impacted soils.
• Surfactant Enhanced MMPE on MW-13 to abate LNAPL.
• Following abatement of LNAPL, emplacement of ISCO agent to reduce dissolved phase petroleum impacts to concentrations less than GCLs.
• Continue semi-annual monitoring of site monitoring wells.

WR appreciates the opportunity to be of service in the completion of these assessment activities. Should you have questions, comments, or require additional information, please contact WR at your earliest convenience.

Dear Matt James:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 4/28/2021 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2012) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Angela D Overcash Senior Project Manager
