Former Billy’s Mini Mart – NCDEQ Incident #3327 WR Project # 23‐0307‐AF Groundwater Monitoring Report September 2023 3 SECTION B. EXECUTIVE SUMMARY 1. Summary of Activities Associated with Current TA WithersRavenel, Inc. (WR) conducted a groundwater and water supply well sampling event at the Billy’s Mini Mart site located at 3121 NC Highway 86 in Hillsborough, Orange County, North Carolina in association with task authorization (TA) TA‐01 approved on June 29, 2023 under North Carolina Department of Environmental Quality (NCDEQ) Contract #N70522‐C. The scope of work for this project included sampling existing monitoring wells MW‐1, MW‐2R, MW‐3, MW‐4, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9R, MW‐13, MW‐15, MW‐18, and MW‐19 and active water supply wells WSW‐1, WSW‐2, WSW‐3, WSW‐4, WSW‐5, and WSW‐6. 2. Soil, Groundwater and LNAPL Assessment Information Soils No soil samples were obtained in connection with this task authorization. To date, assessment of soil impact at the site has not been performed to determine the extent of soil contamination exceeding Maximum Soil Contaminant Concentrations (MSCCs), however, the 1999 Comprehensive Site Assessment (CSA) completed by Stratus Environmental Services, LLP (Stratus) mapped the “approximate lateral extent of petroleum hydrocarbons in soil”. Groundwater Analytical data for groundwater samples collected from site monitoring wells during August 2023 indicated the presence of one or more targeted compounds exceeding the North Carolina Groundwater Quality Standards (2L Standards) in samples from monitoring wells MW‐4, MW‐8, MW‐9R, and MW‐13. No compounds were reported at concentrations exceeding the Gross Contamination Levels (GCLs). Based on measurements obtained in August 2023, groundwater flow was determined to generally be to the south and southeast. Previous interpretations of groundwater flow have generally trended to the south through the site, with some movement to the north on the northern part of the site. This disparity could be due in part to the potential influence of the septic system and associated leach field on the site, located in the vicinity of MW‐2R and MW‐16, or to fluctuations in general groundwater elevations at the location. Light Non‐Aqueous Phase Liquid (LNAPL) LNAPL has historically been detected in monitoring wells MW‐8, MW‐11, and SRW‐1 during previous monitoring events. LNAPL was not measured during the August 2023 sampling event. 3. Receptor Information WR performed a receptor survey at the site in September 2002. Thirty water supply wells were identified within a 1,000‐foot (ft) radius of the release area, one of which (WSW‐1) is located in the northeast corner of the site. Municipal water is not available to the site or surrounding WithersRavenel Our People. Your Success. Former Billy’s Mini Mart – NCDEQ Incident #3327 WR Project # 23‐0307‐AF Groundwater Monitoring Report September 2023 4 properties. Private water supply well information is included in Table B‐5A, and supply well locations are depicted on Figure 8. Based on information obtained from the NCDEQ Source Water Assessment Program (SWAP) website, the on‐site water supply well is identified as a transient non‐community water system (PWS ID NC0368479). The nearest surface water feature identified in proximity to the site is an un‐named pond located approximately 600 feet to the south/southwest of the site. 4. Remediation Activities Based on WR’s review of historical files available for the site, the following remedial activities have been completed at the location: Underground storage tank (UST removal) and soil excavation activities were conducted at the site during December 1986. Following assessment activities, a groundwater pump and treatment system was brought online in 1988 and operated until at least 1999 at the location. However, sometime after 1999, the system was taken offline. In February 2013, a 96‐hour Mobile Multi‐ Phase Extraction (MMPE) event was conducted at the site, during which 3,115 gallons (gal) of impacted groundwater were recovered and approximately 307.31 gal of volatile product were extracted. No additional remedial activities have been performed at the site, with the exception of the placement of Provectus® ORS™ well sleeves in MW‐11, MW‐14 and RW‐3 in December 2018 and the replacement of these well booms in December 2019. 5. Recommendations Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:  Continue performance of groundwater and supply well sampling to determine contaminant trends and ensure supply wells do not show impact.  Complete an updated receptor survey within 1,000ft. radius of the source area. The most receptor survey was completed 21 years ago.  If funding allows, complete soil and groundwater assessment through use of Membrane Interface Hydraulic Profiling Tool (MiHPt) in conjunction with groundwater assessment focused on collection of data for determination of a suitable chemical amendment for remediation at the facility.

SITE HISTORY AND CHARACTERIZATION The following information summarizes the site history and characterization. 1. UST Information Previous reports indicated a UST system was present at the site in the 1980s and 1990s which consisted of one 8,000‐gal and two 4,000‐gal gasoline USTs. The 8,000‐gal and one of the 4,000‐ gal USTs and the associated dispenser island were located west of the building while the second 4,000‐gal UST was located on the north side of the existing building. A release was discovered during November 1986 when Home Oil Company (UST owner) reported to NCDEQ that 1,000 to 2,000‐gallons of gasoline were unaccounted for from the 4,000‐gal UST located west of the building. As a result, this UST was replaced in December 1986. A split in one of the welded seams of the tank was discovered during its removal. Current and historical UST information is included in Table B‐1. In October 2000, the two USTs located west of the building (the 8,000‐gal and the 4,000‐gal tanks) were closed by way of removal and replaced with a 10,000‐gal and a 6,000‐gal UST. The replacement tanks were installed north of the building. During the installation of these new USTs, the contractor noted the presence of an additional 4,000‐gal tank, which was left in place adjacent to the new UST pit. NCDEQ records indicate that this 4,000‐gal UST was closed in 2008. 2. Description of Release/General Assessment History The following summary of the assessment history is based on WR’s review of historical files for the subject incident including:  A release of petroleum was discovered in 1986, when at least two of the USTs located on the property were removed and soil was excavated to 22 ft below land surface (bls). A groundwater pump and treat system was later installed and began operation in 1988. It is unclear when treatment system operations terminated at the location, but it was estimated to have been sometime after 1999. Two water supply wells sampled in 1988 were found to be impacted by methyl tert‐butyl ether (MTBE) (Penland – 213 parts‐per‐billion or “ppb” and Bledsoe – 28 ppb). Supply wells sampled in 2002 indicated an MTBE concentration of 3 ppb in one well sampled (Gates). A Comprehensive Site Assessment (CSA) was completed for the release in June 1999, which recommended dual‐phase vacuum extraction at the site. Pilot testing, that included SVE, step‐drawdown testing and pump testing for the completion of a Corrective Action Plan (CAP) was performed in August 1999. Based on the 1999 CSA, municipal water is not available in the vicinity of the site and soil contamination had not been properly assessed. Only one soil sample was collected from the vadose zone at the location, obtained during the installation of DW‐1.  WR performed a receptor survey in September of 2002 and determined the following: thirty supply wells were identified within 1,000 ft of the site; municipal water is not available to the site or surrounding properties; the nearest surface water feature is an un‐named pond located approximately 600 feet to the south/southwest of the site; the site and surrounding areas are WithersRavenel Our People. Your Success. Former Billy’s Mini Mart – NCDEQ Incident #3327 WR Project # 23‐0307‐AF Groundwater Monitoring Report September 2023 6 rural consisting of large lots used primarily for single‐family residential use, or remain undeveloped; and the land use at the site is small business retail.  WR collected groundwater samples from the existing monitoring/recovery wells at the site on June 1, 2004. Based on the laboratory analytical report, petroleum compounds were detected at concentrations above 2L Standards in samples collected from monitoring wells MW‐1, MW‐ 4, MW‐6, MW‐8, MW‐9, MW‐10, RW‐3, DW‐2 and SRW‐1. No supply wells were sampled during this groundwater sampling event. Groundwater elevation data indicated that groundwater flow direction at the site was to the south/southeast with an approximately gradient of 0.04 ft/ft.  WR personnel were onsite on September 29, 2005 to collect groundwater samples from the existing monitoring/recovery wells at the location (MW‐1 through MW‐10, DMW‐1, DMW‐ 2, RW‐3, SRW‐1 and SRW‐2). LNAPL was detected in monitoring well MW‐8. Based on the laboratory analytical report, petroleum compounds were detected at concentrations above 2L Standards in samples collected from monitoring wells MW‐4, DMW‐1, DMW‐2, SRW‐1, and SRW‐2.  WR personnel were onsite on November 2 and 3, 2006 to collect groundwater samples from the existing monitoring/recovery wells at the site (MW‐1 through MW‐10, DMW‐1, DMW‐2, RW‐3, and SRW‐1) and from six water supply wells located in the immediate vicinity of the site (Ken’s [WSW‐1], Bledsoe [WSW‐2], Gates [WSW‐3], Murray [WSW‐4], Page [WSW‐6], and Huskins [WSW‐7]). LNAPL was not detected in the monitoring wells during this sampling event. Monitoring wells MW‐1, MW‐9, and MW‐10 were dry and not able to be sampled. Based on the laboratory analytical report, petroleum compounds were detected at concentrations above 2L Standards in samples collected from monitoring wells MW‐4, MW‐8, RW‐3, DMW‐1, and SRW‐1. No targeted compounds were detected above laboratory detection limits in the supply well samples.  WR personnel were onsite on November 4, 2008 to collect groundwater samples from the existing monitoring/recovery wells at the site (MW‐1 through MW‐10, DMW‐1, DMW‐2, RW‐ 3, and SRW‐1). LNAPL was not detected in the monitoring wells during this sampling event. WR personnel also collected groundwater samples from six water supply wells located in the immediate vicinity of the site (WSW‐1, WSW‐2, WSW‐3, WSW‐4, WSW‐6, and WSW‐7). Groundwater analytical results showed petroleum compounds at concentrations above 2L Standards in samples collected from monitoring wells MW‐8, DMW‐1, and SRW‐1. The groundwater dissolved contaminant plume was determined to be delineated. No targeted compounds were detected in the supply wells that were sampled. Groundwater flow direction at the site was determined to be to the southeast.  Additional groundwater monitoring events were conducted on August 14, 2009, March 25, 2010, November 8, 2011, and November 29, 2012. During one event, LNAPL was present in monitoring well MW‐8 at a thickness of 0.31 feet. Petroleum compounds were detected above the 2L Standards in monitoring wells MW‐4, MW‐10R, DMW‐1, SRW‐1, and SRW‐2. Analytical results of the water supply well samples indicated the presence of MTBE in samples collected from wells WSW‐1, WSW‐2, and WSW‐6 at concentrations below the 2L Standard. WithersRavenel Our People. Your Success. Former Billy’s Mini Mart – NCDEQ Incident #3327 WR Project # 23‐0307‐AF Groundwater Monitoring Report September 2023 7  An MMPE event was conducted for 96 hours in February 2013. At the conclusion of the event, 3,115 ‐gal of contaminated water and 307.31 ‐gal of volatilized product had been removed from monitoring well MW‐8.  WR completed a groundwater sampling event in November 2014. Groundwater samples were collected from wells MW‐3, MW‐4, MW‐5, MW‐7, MW‐8, MW‐9R, MW‐10R, RW‐3, DW‐1, DW‐2, and SRW‐1. Supply wells WSW‐1, WSW‐6 and WSW‐7 were also sampled. LNAPL was measured in monitoring well MW‐11 at a thickness of 0.01 ft. Benzene exceeded the GCL in monitoring well MW‐9R. Monitoring wells DW‐1, MW‐4, MW‐8, MW‐9R, MW‐10R, and SRW‐1 exhibited concentrations that exceeded their respective 2L standards. Monitoring wells MW‐3, MW‐5 and MW‐7 and water supply wells WSW‐1, WSW‐6, and WSW‐7 did not contain VOCs at concentrations that exceeded the laboratory detection limits.  In May 2015, WR installed monitoring wells MW‐12, MW‐13, MW‐14, MW‐15, MW‐16 and MW‐17 and performed a groundwater sampling event at the site. Monitoring wells MW‐4, MW‐8, MW‐9R, MW‐10R, MW‐11, MW‐12, MW‐13, MW‐14, MW‐17, DW‐1, DW‐2, SRW‐ 1 and RW‐3 contained concentrations exceeding their respective 2L Standards. Benzene was reported at concentrations exceeding the GCL for the compound in samples from MW‐9R and MW‐13. Numerous compounds exceeded their respective GCLs in MW‐11. Based on measurements obtained during the May 2015 groundwater sampling event at the site, groundwater flow appeared to trend to the southeast through the site.  In October 2015, WR personnel gauged LNAPL levels within MW‐11 and MW‐14, and gauged, purged and sampled monitoring wells MW‐2R, MW‐3, MW‐4, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9R, MW‐10R, MW‐12, MW‐13, MW‐15, MW‐16, MW‐17, DW‐1, DW‐2 and SRW‐1 and supply wells WSW‐1, WSW‐2, WSW‐3, WSW‐4, WSW‐5 and WSW‐6 for VOC analysis. Analytical data for groundwater samples obtained from monitoring wells at the site indicated the presence of one or more targeted compounds in samples obtained from wells MW‐4, MW‐ 5, MW‐8, MW‐9R, MW‐10R, MW‐12, MW‐13, MW‐17, DW‐1, DW‐2 and SRW‐1 at concentrations exceeding their respective 2L Standards. Benzene was reported at a concentration exceeding the GCL in the sample from MW‐9R. The presence of LNAPL in wells MW‐11 and MW‐14 also represents a GCL violation. WR also obtained LNAPL samples from monitoring well MW‐11 and the two active USTs (UST‐1 and UST‐2) located on the property for product identification “fingerprint” analyses. Not accounting for possible degradation of select chemical compounds, initial results of fuels and LNAPL testing showed no direct correlation between the UST samples and the LNAPL sample obtained from MW‐11. Further laboratory interpretation of these data revealed that the fuels contained in USTs 1 and 2 do not match the product within monitoring well MW‐11.  In April 2017, WR personnel gauged LNAPL levels within MW‐11 and MW‐14, and gauged, purged and sampled monitoring wells MW‐1, MW‐2R, MW‐3, MW‐4, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9R, MW‐10R, MW‐12, MW‐13, MW‐15, MW‐16, MW‐17, DW‐1, DW‐2 and SRW‐1 and supply wells WSW‐1, WSW‐2, WSW‐3, WSW‐4, WSW‐5 and WSW‐6 for VOC analysis. One or more compounds in samples obtained from wells MW‐4, MW‐5, MW‐8, MW‐ 9R, MW‐10R, MW‐12, MW‐13, MW‐17, DW‐1, DW‐2 and SRW‐1 at concentrations WithersRavenel Our People. Your Success. Former Billy’s Mini Mart – NCDEQ Incident #3327 WR Project # 23‐0307‐AF Groundwater Monitoring Report September 2023 8 exceeding their respective 2L Standards. Benzene was reported at a concentration exceeding the GCL in the sample from MW‐9R. The presence of LNAPL in wells MW‐11 and MW‐14 also represents a GCL violation. Analytical data for supply well samples obtained from WSW‐ 1, WSW‐2, WSW‐3 and WSW‐4 indicated the presence of chloroform in the samples at levels above the laboratory method detection limit (MDL) for SM6200B but beneath the NC 2L Standard for the compound. There is no standard for chloroform listed by the US EPA Region IV Maximum Contaminant Levels (MCL), December 2009. Based on measurements obtained during the April 2017 groundwater sampling event at the site, groundwater flow appears to trend to the south and southeast through the location.  WR personnel completed a groundwater and supply well sampling event between November 29 and December 18, 2018. One or more compounds in samples obtained from wells MW‐8, MW‐9R, MW‐12, MW‐13, MW‐17, DW‐2 and SRW‐1 were detected at concentrations exceeding their respective 2L Standards. Benzene was reported at a concentration exceeding the GCL for the compound in the sample from MW‐13. LNAPL was measured in wells MW‐ 11 (0.02 ft) and MW‐14 (0.01 ft). Analytical data for supply well samples showed bromodichloromethane present in the sample obtained from WSW‐1 at a concentration exceeding the 2L Standard. Data for samples obtained from WSW‐1, WSW‐2 and WSW‐4 showed the presence of chloroform in the samples at levels above the laboratory MDL for SM6200B but beneath the NC 2L Standard for the compound. Analytical data for supply well samples obtained from WSW‐3, WSW‐5 and WSW‐6 did not indicate the presence of target compounds at levels above their MDLs for SM6200B.  WR personnel completed a groundwater and supply well sampling event between December 30, 2019 and January 20, 2020. One or more compounds detected in samples from MW‐4, MW‐8, MW‐9R, MW‐10R, MW‐11, MW‐12, MW‐13, MW‐14, MW‐17 and SRW‐1 were reported at concentrations exceeding their respective 2L Standards. Benzene was reported at a concentration exceeding the GCLs in the samples obtained from MW‐9R and MW‐13. Analytical data for supply well samples showed acetone present in the sample obtained from WSW‐1 at a concentration beneath the 2L Standard, and chloroform in samples from WSW‐ 1, WSW‐3 and WSW‐4, also at concentrations beneath the 2L Standard. Based on data for wells WSW‐1, WSW‐3 and WSW‐4, the NCDEQ Incident Manager for the site (Mr. Mark Petermann) requested that WR re‐sample these wells. Results of SM6200B analysis of these samples showed chloroform present in samples from WSW‐3 and WSW‐4 at levels beneath the 2L Standard. Chloromethane was reported in each of the supply wells (WSW‐1, WSW‐3 and WSW‐4) at concentrations above the 2L Standard for the compound.  WR personnel completed a groundwater and supply well sampling event in May 2021. One or more compounds detected in samples from MW‐4, MW‐8, MW‐9R, MW‐11, MW‐12, MW‐ 13, MW‐14, MW‐17, DW‐2, and SRW‐1 were reported at concentrations exceeding their respective 2L Standards. None of the contaminants were reported at concentrations exceeding the GCLs. Chloroform was shown present in samples from WSW‐1, WSW‐2, WSW‐3, WSW‐4, and WSW‐6 at concentrations beneath the 2L Standard. Bromodichloromethane and chlorodibromethane were also present in water supply well WSW‐1. WR attributes the presence of these chemicals in the samples to shock chlorination of the supply wells. Data for samples from supply well WSW‐5 did not show contaminants at WithersRavenel Our People. Your Success. Former Billy’s Mini Mart – NCDEQ Incident #3327 WR Project # 23‐0307‐AF Groundwater Monitoring Report September 2023 9 concentrations exceeding the laboratory MDL for SM6200B.  In November and December 2021, WR conducted limited assessment activities to attempt to determine if the plumes surrounding MW‐4 and MW‐13 were related. WR installed one temporary well and sampled additional wells within each plume. WR collected groundwater samples and submitted the samples to Waypoint for Environmental Protection Agency (EPA) Method 8260 for volatile organic compounds (VOCs) and to Microbial Insights for Compound‐ Specific Isotope Analysis (CSIA). Based on results of the CSIA, it appears the areas of impact around MW‐13 extending to MW‐12 and MW‐17 and the impacted area around MW‐4 are related. Based on the dual isotope plot obtained from the CSIA, the δ13C values do not appear to become more positive in the downgradient direction (MW‐12 to MW‐4, MW‐12 to TW‐1); therefore, evidence of degradation is not present. The dual isotope plot points for MW‐4 and MW‐13 are almost identical which does not support the hypothesis of two different source areas for the impacts observed in these two wells. WR also supervised the installation of two permanent Type II monitoring wells (MW‐18 and MW‐19) to further define the extent of impact. These wells did not indicate impacts in excess of the 2L Standards.  August 2022, WR personnel gauged, purged and sampled monitoring wells MW‐1, MW‐2R, MW‐3, MW‐4, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9R, MW‐10R, MW‐13, MW‐15, MW‐18, and MW‐19 and supply wells WSW‐1, WSW‐2, WSW‐3, WSW‐4, WSW‐5 and WSW‐6 for VOC analysis. No compounds were found at concentrations exceeding their respective GCL’s. Source area monitoring wells MW‐4, MW‐8, and MW‐R9 indicated concentrations above their 2L Standards. Analytical data for supply well samples obtained from WSW‐2, WSW‐3 and WSW‐4 indicated the presence of chloroform in the samples at levels above the laboratory method detection limit (MDL) for SM6200B but beneath the NC 2L Standard for the compound. 3. Brief Description of Site Characteristics The site is located in Hillsborough, Orange County, North Carolina (Figure 1) and includes an area of approximately 1.6 acres. The facility is located at 3121 NC Highway 86 and includes the following improvements: A one‐story brick/block building (the former Billy's Mini Mart) currently operating as Ken's Quickie Mart. A wood‐framed addition is located at the rear of the building along the eastern wall. Approximately 30% of the site surface is covered with asphalt or concrete. Active UST systems are contained within a UST area located near the northeastern corner of the building on site. These USTs supply dispensers are located beneath a canopy located near the northwestern corner of the building. Potable water utilized on the site is obtained from a supply well located near the northeastern corner of the property (WSW‐1). An additional (out of service) supply well is located southwest of the site building, between monitoring wells MW‐6 and MW‐ 8. A septic system is located to the east of the site building. Site features, improvements and monitoring well locations are shown on Figure 2. Site photographs are included in Appendix A. The surrounding area consists mainly of private residences and undeveloped properties. Carolane Propane Gas Company maintains a facility located to the north of the site, on the northern side of Phelps Road. Municipal water is not currently available to the site or surrounding properties. WithersRavenel Our People. Your Success.

Information on Receptors/Potential Receptors A receptor survey was performed in association with the release at the site by WR in September 2002 and included the following findings:  Thirty water supply wells were identified within 1,000 ft of the site,  An un‐named surface water body (pond) is located approximately 600 feet south‐southwest of the site,  No public water supply was found to be available to the site or surrounding properties. Private water supply well information is included in Table B‐5A, and well locations are depicted on Figure 8. 5. Regional and Site Geology and Hydrology The Geologic Map of North Carolina depicts the site in the as being underlain by felsic metavolcanic rock of the Cambrian to Late Proterozoic that is described as light gray to greenish gray metamorphosed dacitic to rhyolitic flows and tuffs interbedded with mafic and intermediate metavolcanic rock, meta‐argillite, and metamudstone. According to the United States Department of Agricultural (USDA) Natural Resources Conservation Service (NRCS) Web Soil Survey, the source area is underlain by Herndon silt loam (2 to 6 percent slopes). Herndon silt loam is well drained, found on summit interfluves, and the parent material is residuum weathered from phyllite. Well construction records for monitoring wells MW‐12 through MW‐17 indicated that soils beneath the site are predominantly clay to clayey silt with auger refusal encountered at approximately 39 bgs. SECTION D. GROUNDWATER SAMPLING – AUGUST 2023 In August 2023, WR personnel mobilized to the subject property to perform limited groundwater sampling activities at the facility in association with TA‐01 under NCDEQ Contract # N70522‐C. The scope of work for this project included the gauging, purging, and sampling of monitoring wells MW‐1, MW‐2R, MW‐3, MW‐4, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9R, MW‐13, MW‐15, MW‐ 18, and MW‐19 and active water supply wells WSW‐1, WSW‐2, WSW‐3, WSW‐4, WSW‐5, and WSW‐6. The following paragraphs describe the sampling activities and associated laboratory analytical results. Groundwater Sampling Activities Prior to the purging and sampling of site monitoring wells as described below, WR personnel gauged the wells with an electronic oil‐water interface meter to determine the depth to LNAPL and groundwater at each well location. During the performance of these activities, LNAPL was not identified in the monitoring wells. WithersRavenel Our People. Your Success. Former Billy’s Mini Mart – NCDEQ Incident #3327 WR Project # 23‐0307‐AF Groundwater Monitoring Report September 2023 11 The depth to groundwater measurements in the monitoring wells across the site ranged from 27.40 feet below the top of casing (ft‐BTOC) in monitoring well MW‐18 to 33.00 ft‐BTOC in monitoring well MW‐6. Based on groundwater elevation measurements on August 1 and 2, 2022, the direction of groundwater flow is generally towards the south and southeast. Groundwater flow as determined based on these measurements is shown on Figure 3. Groundwater elevation measurements for this event are presented in Table B‐7. Historical groundwater elevations are summarized in Table B‐9. Following gauging, the monitoring wells were purged and sampled with separate, disposable polyethylene (PE) bailers for each well. Samples from the wells were decanted into pre‐preserved laboratory provided sample containers. Samples collected from site monitoring wells were submitted to Waypoint Analytical, Inc. (Waypoint) for testing by Standard Method (SM) 6200B plus oxygenates. Additionally, WSW‐1 through WSW‐6 were purged prior to sampling by allowing the closest exterior spigot connected to the well to run for a minimum of 10‐minutes each to allow the well pump to purge out any stagnant water in the line. After allowing the wells adequate time to purge, samples were collected from these water supply wells. The water supply well samples were submitted for laboratory analysis of VOCs by SM6200B. Laboratory Results Analytical data for groundwater samples collected from site monitoring wells during August 2023 indicated the following:  No LNAPL was measured in any of the gauged monitoring wells.  None of the sampled monitoring wells contained concentrations exceeding the GCL.  Source area monitoring wells MW‐4, MW‐8, MW‐9R, and MW‐13 indicated concentrations above the 2L Standards.  Perimeter monitoring wells MW‐1, MW‐2R, MW‐3, MW‐5, MW‐6, MW‐7, MW‐15, MW‐ 18, and MW‐19 did not indicate concentrations above the 2L Standards.  Chloroform was shown present in samples from WSW‐2, WSW‐3, and WSW‐4 at concentrations beneath the 2L Standard. WR attributes the presence of these chemicals in the samples to shock chlorination of the supply wells.  Data for samples from supply wells WSW‐1, WSW‐5, and WSW‐6 did not show contaminants at concentrations exceeding the laboratory MDL for SM6200B. Groundwater analytical results are summarized in Table B‐4 and shown on Figure 4. Isoconcentration maps showing benzene, naphthalene, and MTBE are included as Figures 5, 6, and 7, respectively. Historical groundwater analytical results are summarized in Table B‐4A. Copies of the laboratory analytical report and chain‐of‐custody are included in Appendix B. WR’s generalized standard operating procedures are provided in Appendix C. WithersRavenel Our People. Your Success.

CONCLUSIONS AND RECOMMENDATIONS This report documents the results of field activities conducted at the site August 1 through 2, 2023. Conclusions based on assessment and sampling activities, combined with analytical data historical information at the site include the following:  No public or private water supply system services the site or surrounding area,  As many as 30 water supply wells are located within 1,000 ft of the source area.  Chloroform was shown present in samples from WSW‐2, WSW‐3, and WSW‐4 at concentrations beneath the 2L Standard. WR attributes the presence of these chemicals in the samples to shock chlorination of the supply wells.  Data for samples from supply wells WSW‐1, WSW‐5, and WSW‐6 did not show contaminants at concentrations exceeding the laboratory MDL for SM6200B.  No LNAPL was measured in any of the monitoring wells gauged in association with sampling in August 2023.  None of the monitoring wells contained concentrations exceeding the GCL.  Source area monitoring wells MW‐4, MW‐8, MW‐9R, and MW‐13 indicated concentrations above the 2L Standards.  Perimeter monitoring wells MW‐1, MW‐2R, MW‐3, MW‐5, MW‐6, MW‐7, MW‐15, MW‐ 18, and MW‐19 did not indicate concentrations above the 2L Standards. The plume is defined and appears stable.  Based on data for soil samples collected in association with assessment activities performed at the site to date, the extent of soil contamination at the site has not been defined to levels equivalent to the Soil‐to‐Water, Residential, or Industrial/Commercial MSCCs.  Based on groundwater level measurements conducted at the site during August 2023, groundwater flow direction is to the south and southeast. Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:  Continue performance of groundwater and supply well sampling to determine contaminant trends and ensure supply wells do not show impact.  Complete an updated receptor survey within 1,000ft. radius of the source area. The most receptor survey was completed 21 years ago.  If funding allows, complete soil and groundwater assessment through use of MiHPt in conjunction with groundwater assessment focused on collection of data for determination of a suitable chemical amendment for remediation at the facility.

Former Billy’s Mini Mart – NCDEQ Incident #3327 WR Project # 23-0307-AF Groundwater Monitoring Report August 2023 APPENDIX C GENERAL STANDARD OPERATING PROCEDURES Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Soil Sampling, Soil Boring and Monitor Well Installation, Well Development Soil borings are installed utilizing a stainless-steel hand auger, direct-push hydraulic drill or auger rotary drill using either a macro core™ sampler, hollow stem augers, or air rotary roller cone bit. Soil borings are typically sampled at discrete intervals from the bucket of a clean stainless steel hand auger, direct push stainless steel sampler with acetate sleeve, or a split barrel sampler. When appropriate, soil samples may be collected from drill cuttings associated with the boring or well installation. Monitor wells are constructed within select soil borings of one, two, or four-inch inside diameter PVC casing and machine slotted screen in accordance with NCAC Title 15A, Subchapter 02C (Well Construction Standards, Criteria and Standards Applicable to Water Supply and Certain Other Wells). Clean-washed “#2 Torpedo Sand” is typically utilized to fill the boring annulus surrounding the well screen, extending to a minimum of 1-foot above the well screen. A minimum 1-foot thick bentonite clay seal is emplaced above the sand pack and hydrated. Neat cement grout is placed in the remaining annulus space from the upper portion of the bentonite seal to within 1-foot of surface grade. In coastal plain areas where shallow groundwater is encountered, a variance to construction standards may be employed to ensure the upper portion of the well screen intersects the upper aquifer surface. Wellheads may be completed with either concrete-set flush mounted traffic-bearing steel skirted manholes with bolt down covers or steel above-ground “stick-up” well protectors set in a concrete pad. The monitoring wells are secured with locking caps. Temporary wells or piezometers may be completed with the PVC riser cut at or above grade, and are abandoned within 24-hours of their installation. Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or peristaltic pump, dependent upon site conditions. When wells are developed by the driller, they may be developed with any of the methods outlined above, in addition to air or water injection. Soil boring logs and well construction details are typically prepared for presentation in a report appendix. Borings completed in bedrock may be drilled using air rotary, coring, or sonic drilling methods. Groundwater Depth to Water Measurements Groundwater level measurements are typically obtained using an electronic water level indicator which registers a tone and/or illuminated light when the probe contacts groundwater. Depth to groundwater measurements are obtained by lowering the probe attached to a cable usually marked in 0.01 foot intervals into the well until the probe of the meter intersects the water surface. The measurement from the top of the riser pipe or top of casing (TOC) to the water level is recorded to the nearest 0.01 foot. The electronic water level indicator probe and exposed probe cable is decontaminated between measurement locations. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Free Product Level Measurements Light Non-Aqueous Phase Liquid (LNAPL) or “free product” present on the water table is measured using an electronic oil/water interface probe. The interface probe has both an audible and illuminating light that indicate when a liquid level is encountered. The oil/water interface probe registers a solid tone and solidly lit light when LNAPL petroleum product is encountered and a beeping tone flashing light when groundwater is encountered. Depth to LNAPL measurements are obtained by lowering the probe attached to a cable marked in 0.01 foot intervals into the well until the probe of the meter intersects the product or groundwater. The measurements from the top of the riser pipe or TOC to the liquid level are recorded to the nearest 0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to LNAPL measurement from the depth to groundwater measurement. The electronic interface probe is decontaminated between measurement locations. Soil Sampling and Field Screening Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable. Sampling procedures are followed to protect the chemical integrity of the soil samples and minimize the potential for cross contamination between sample locations, including discarding of the exterior of the sample which contacts the auger bucket, acetate sleeve, or split barrel sampler, the use of stainless steel sampling equipment, and the thorough decontamination of sampling apparatus prior to use and between sample locations. Soil samples retained as a part of excavation or other intrusive “digging” activities may be collected from the bucket of excavation equipment or using a hand shovel, if appropriate. Care to collect soil samples from excavation equipment includes retrieving native soil from material that has not made contact with the excavating equipment. Samples are collected in sealable bags or by directly filling sample containers as described above. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination or field personnel exposure to contaminants. Sampling equipment such as hand auger extensions and buckets, direct push samplers, split spoons or shovels, are decontaminated prior to their use in the collection of samples. Samples are placed within laboratory grade sample containers provided by the laboratory to which the samples are submitted, labeled, sealed, and placed in an ice filled cooler. An aliquot of the sample is typically placed in a clean sealable bag and allowed to reach ambient air temperature for future screening of volatile vapor content with a photoionization detector (PID), flame-ionization detector (FID) or other portable screening device. Screening of samples with a PID, FID or other field screening device is performed in accordance with device manufacturer specifications for screening, following calibration of the instrument based on manufacturer recommended procedures. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Groundwater Sampling Groundwater samples are generally collected using one of three standard methods – through the use of a dedicated, disposable bailer, a peristaltic pump or submersible electric pump. When sampling with a bailer, a minimum of three well volumes of groundwater are extracted from the well as a means of purging, unless the well is purged to a “dry” state prior to the removal of three volumes of water. Prior to collection of the groundwater sample with the bailer, the water level is allowed to recover to within 80% of the original level measured prior to purging. When sampling with a peristaltic or submersible electric pump, polyethylene (PE) tubing (or equivalent) is emplaced into the screened section of the monitoring well, and the pump is used to extract water through the tubing. When using the either of these methods, general water quality measurements including but not limited to pH, temperature, dissolved oxygen (DO), oxygen reductive potential (ORP), specific conductivity and turbidity may be used as methods for determining when an adequate purge of the well has been conducted. When water quality parameters are measured, the resulting data are included in well purge forms or field notes specific to each site and sampling point. Following the purging of three well volumes of groundwater (in the case of the bailed well) or stability of monitored measurements (in the case of the peristaltic or submersible electric pump), the groundwater sample(s) are introduced directly into sample containers provided by the laboratory to which samples are ultimately submitted for analysis. Any samples requiring chemical preservation are contained in pre-preserved container(s) provided by the laboratory. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination of samples or field personnel exposure to contaminants. Water Supply Well Sampling Sampling of water supply wells is accomplished through the collection of a representative sample from an in-line water tap or other point accessible for sampling. Where possible, the sample is collected from a point prior to any filtration or point of entry (POE) system which might be installed on a well. In some cases, samples will be collected from both pre and post-POE locations. Prior to the collection of samples through an in-place sampling point, the tap or sampling port is cleaned with an Alconox® and deionized water solution, rinsed with deionized water, and again with an isopropyl alcohol (IPA) rinse. In the case of active supply wells (e.g., a well with a useable well pump with an active power supply), the well pump is energized and allowed to run for a minimum of ten (10) minutes time, after which a sample is contained in laboratory grade sample containers as described in the previous section. Water quality parameters may be (but are not necessarily) measured in association with the well purging. Supply wells without active power supplies are not generally sampled, as the well seal cannot be compromised by individuals not certified as a well contractor. However, in the case of a well with no power supply or pump installed, samples could be obtained through the use of a bailer, peristaltic pump or electric submersible pump. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Decontamination Procedures Decontamination procedures employed in the performance of field activities will vary dependent upon the method(s) of sampling performed at any site, but will generally include the following: • Remove excess soil/sludge from any sampling equipment as needed, • Wash and scrub the equipment with a phosphate-free detergent such as Alconox® or Liquinox® in a contaminant-free tap water solution. Use a brush to remove particulate matter and surface films as necessary, • Rinse thoroughly with tap water, • Rinse thoroughly with analyte-free water (deionized water),  Rinse thoroughly with isopropyl alcohol, • Allow the equipment to air dry, • Prevent inadvertent contamination during storage and transport (accomplished through storage of equipment in foil or plastic bags/sheeting). In the case of disposable bailers and tubing utilized for the purging and sampling of wells, these items may be decontaminated prior to their disposal. In general, no decontamination of these items is necessary prior to their use in sampling.
