(ATC) to prepare a Monitoring Report for the project site located at 1710 Union Grove Road in Lenoir, Caldwell County, North Carolina. Figure 1 shows the site and vicinity on part of a United States Geological Survey (USGS) site topographic map. Figure 2 is a site map which shows site features and monitoring well locations. This report documents the results of a groundwater monitoring event conducted in August 2017. Groundwater impact at the site has historically been identified at concentrations exceeding Gross Contamination Levels (GCLs). Generally decreasing trends have been observed over time. However, according to recent groundwater analytical results, contaminant concentration rebounding appears to be occurring. Petroleum hydrocarbons were detected above the associated 15A NCAC 2L.0202 standards (2L standards) in five of the eight sampled site monitoring wells, and benzene and ethylene dibromide (EDB) were reported in wells MW-1 and MW-2 at concentrations above their respective GCLs in August 2017. Free product has historically been identified at the site with a maximum thickness of 0.78 feet in well MW-2. Free product was not identified in site monitoring wells in August 2017 but a sheen was observed in water from wells MW-1 through MW-3. Based on vicinity water supply wells, historical free product, and groundwater impact in on-site wells, the risk classification for the site has been designated as “High” and ranked H155D by the North Carolina Department of Environmental Quality (NCDEQ). Therefore, groundwater contamination must be remediated to concentrations which are equal to or less than the associated 2L standards. As outlined in the August 2009 Corrective Action Plan (CAP), air sparge and soil vapor extraction (AS/SVE) technologies were the chosen corrective actions for this site based on site conditions and technical considerations. The AS/SVE wells were installed from November 14 to November 22, 2011. The system components were delivered and installed from December 2011 to March 2012. The system was started on April 24, 2012. Based on laboratory analytical results from quarterly effluent air sampling, approximately 3,437 pounds of total BTEX have been recovered by the SVE system since startup. Based on the results of the August 15, 2017, monitoring event, the following site conditions existed: Former Tilley’s Superette January 30, 2018 Monitoring Report Page 2  One or more volatile organic compounds (VOCs) using EPA Method 602 were reported above 2L standards in wells MW-1, MW-2, MW-3, MW-9, and MW-12, and the benzene concentrations in wells MW-1 and MW-2 exceeded the GCL.  Concentrations of EDB reported using EPA Method 504.1 exceeded the 2L standard in samples collected from wells MW-1, MW-2, MW-3, MW-9, and MW-12, and the EDB concentrations in wells MW-1 and MW-2 exceeded the GCL.  The direction of groundwater flow is to the southwest. Former Tilley’s Superette January 30, 2018 Monitoring Report Page 3 2.0 SUPPORTING INFORMATION AND CAP IMPLEMENTATION An underground storage tank (UST) system consisting of six tanks was formerly located on-site and was operated by Cary Oil from April 1, 2005, until October 2006 when the UST system was removed. During UST removals, soil impact was identified and led to assessment requests from the North Carolina Department of Environment and Natural Resources (NCDENR; currently the NCDEQ). Residential properties and rural land surround the property. The subject property is owned by Warren Tilley and includes one building that operates as Narrow Way Baptist Church. Between the late 1950s and August 2006, a grocery store and gas station with a barber shop operated at the site. Site history including on-site UST system information is summarized in Table 1. A site plan that indicates monitoring well locations and other site features is provided as Figure 2. The surface water bodies closest to the site are an unnamed pond and a tributary of Stafford Creek, which are located approximately 2,000 feet south of the site. Surface cover at the site consists mostly of grass, except in front of the building and to the eastern side of the building which is covered with asphalt and gravel. The site lies in the Inner Piedmont in an area characterized by inter-fingered biotite gneiss, biotite schist, and mica schist with some other minor rock types that are heavily metamorphosed and structurally complex. The shallow subsurface contains overburden of soil, saprolite, and partially weathered rock (PWR) that derive from in-place weathering. Depth to rock ranges from ground surface at occasional outcrops to depths of up to 100 feet in areas of easily weathered rock. The soil type encountered during installation of the remediation wells was described as red/brown/tan silt and clay with mica and PWR. Granitic/dioritic gneiss was encountered beginning at depths of approximately 55 to 80 feet below land surface (bls) across the site. Depth to groundwater in the site monitoring wells ranged from approximately 35 to 39 feet below top of casing (TOC) during the August 2017 groundwater sampling event. Based on the recent groundwater level measurements and calculation of groundwater elevations, groundwater flows towards the southwest across the site. Public water, supplied by Baton Water Corporation, is provided to the site and surrounding area. Eighteen (18) supply wells have been identified within approximately 1,500 feet of the site. One private well (PW-7) has historically been reported as being used for potable water and is located approximately 415 Former Tilley’s Superette January 30, 2018 Monitoring Report Page 4 feet sidegradient of the site. ATC recently contacted Baton Water Corporation and water service is now provided to this property located at 1679 Union Grove Road. Two other wells are being used for irrigation and are located approximately 750 feet and 875 feet sidegradient of the site, respectively. Potable water is provided to these properties by Baton Water Corporation. Water supply well information for the area is summarized in Table 3, and supply well locations relative to the source area are depicted on Figure 3. Between 2006 and 2012, site assessment, Aggressive Fluid/Vapor Recovery (AFVR) events for free product recovery, and a CAP with pilot testing were conducted related to the Tilley’s release. Free product recovery efforts in the form of AFVR and Mobile Multi-Phase Extraction (MMPE) events, conducted between 2008 and 2012, recovered approximately 399.98 gallons of petroleum as vapor, 36 gallons of liquid product, and 15,622 gallons of petroleum-contact water. Historical free product recovery information is summarized in Table 7. The site monitoring wells did not indicate free product during post-AFVR gauging conducted on June 6, 2012, and during subsequent groundwater sampling events conducted since August 2012. However, a sheen was observed in groundwater from wells MW-1 through MW-3 during an August 2017 monitoring event. Based on results of the CAP and pilot testing, ATC found that AS and SVE technologies appeared to be the most feasible and cost effective remedial options for reducing groundwater contaminant concentrations associated with the site (Incident No. 28466). With the exception of four SVE wells installed as part of the pilot test in 2009, the system was installed during the period of November 2011 through March 2012. The air sparge system consists of 16 air sparge wells, a rotary claw air compressor, and schedule 80 PVC piping for transferring compressed air from the remediation system to the air sparge wells. The vapor extraction system consists of 14 vapor extraction wells, a regenerative vacuum blower, and schedule 40 PVC piping for transferring extracted vapors from the vapor extraction wells to the remediation system. The system was started on April 24, 2012. Air sparge well AS-2 was started on June 20, 2012, after free product was sufficiently removed from the area. Former Tilley’s Superette January 30, 2018 Monitoring Report Page 5 3.0 GROUNDWATER INVESTIGATION 3.1 Fluid Measurements and Free Product Conditions On August 15, 2017, an oil/water interface probe was used to check for the presence of free product and measure static water levels at monitoring wells MW-1, MW-2, MW-3, MW-5D, MW-9, MW-12, MW-16D, and MW-18. The groundwater elevations were determined in reference to the surveyed top-of-casing elevations. Relevant field methods are summarized in Appendix A. Groundwater elevations were calculated based on the August 15, 2017, gauging data, and a summary of historical groundwater elevation data is included in Table 4. A groundwater elevation contour map, based on the August 2017 static water level data, is included as Figure 4. The groundwater potentiometric surface indicates that groundwater at the site generally flows towards the southwest. Historically, free product has been detected in monitoring wells MW-2, MW-3, and vapor extraction wells VE-1, VE-2, and VE-3. During the August 2017 monitoring well gauging activities, free product was not identified in the site monitoring wells but a sheen was observed in groundwater from wells MW-1 through MW-3. 3.2 Groundwater Sampling Groundwater samples were obtained from monitoring wells MW-1, MW-2, MW-3, MW-5D, MW-9, MW- 12, MW-16D, and MW-18 on August 15, 2017. Prior to sampling, each well was purged of three standing water columns, or until the well was purged dry. Samples were then collected with new disposable bailers and poured directly into laboratory-provided containers with appropriate preservatives. The samples were placed in a chilled cooler and submitted to North Carolina-accredited Shealy Environmental Services, Inc. of Columbia, South Carolina, using proper chain-of-custody procedures for laboratory analyses. Groundwater samples from the monitoring wells were analyzed for volatile organic compounds by EPA Method 602 including BTEX (benzene, toluene, ethylbenzene, and total xylenes), methyl-tert butyl ether (MTBE), and isopropyl ether (IPE) and by EPA Method 504.1 for EDB. According to the analytical results, concentrations of petroleum hydrocarbons were detected above the associated 2L standards in monitoring wells MW-1, MW-2, MW-3, MW-9, and MW-12. Specifically, laboratory results indicated the following: Former Tilley’s Superette January 30, 2018 Monitoring Report Page 6  One or more volatile organic compounds (VOCs) using EPA Method 602 were reported above 2L standards in wells MW-1, MW-2, MW-3, MW-9, and MW-12, and the benzene concentrations in wells MW-1 and MW-2 exceeded the GCL.  Concentrations of EDB reported using EPA Method 504.1 exceeded the 2L standard in samples collected from wells MW-1, MW-2, MW-3, MW-9, and MW-12, and the EDB concentrations in wells MW-1 and MW-2 exceeded the GCL. Based on these results, groundwater contamination is generally located along the south side of the subject site in the vicinity of, and downgradient from, the former UST system. Groundwater contaminant concentrations generally decreased in monitoring well MW-1 but generally increased in wells MW-3, MW-9, and MW-12 between February and August 2017. Contaminant concentrations in well MW-2 increased significantly between February and August 2017. Groundwater analytical results obtained in August 2017 are summarized in Table 5. Isoconcentration maps for dissolved benzene, toluene, ethylbenzene, total xylenes, MTBE, and EDB are depicted as Figure 5 through Figure 10, respectively. A historical summary of groundwater analytical results is provided in Table 6. Copies of the August 2017 laboratory analytical report and chain-of-custody forms are included in Appendix B. Former Tilley’s Superette January 30, 2018 Monitoring Report Page 7 4.0 CONCLUSIONS AND RECOMMENDATIONS A groundwater sampling event was conducted at the Former Tilley’s Superette on August 15, 2017. Impact to groundwater in the source area continues to exceed the 2L Standards, and benzene and EDB concentrations in wells MW-1 and MW-2 exceed their respective GCLs. Groundwater contaminant concentrations generally decreased in monitoring well MW-1 but generally increased in wells MW-3, MW-9, and MW-12 between February and August 2017. Contaminant concentrations in well MW-2 increased significantly between February and August 2017. A review of historical soil contaminant concentrations does not indicate sufficiently elevated sorbed contamination to indicate a continued source of impact to groundwater. However, it is possible there is unidentified remaining soil impact or product in the subsurface that is resulting in the elevated dissolved contaminant levels. ATC has previously recommended system enhancements to potentially increase efficiency, such as replacement of the source area 2” SVE wells with 4” SVE wells and a sparge test to identify if using shallower sparge wells is an option for remediating shallow aquifer groundwater. The trust fund will not cover the costs for these proposed system enhancements. Alternative options include:  installation of 4” diameter recovery wells for AFVR events. The AFVR events could be conducted with sparge enhancement using impacted monitoring wells (MW-1 through MW-3, depending on recovery well locations);  if recovery events are conducted, a laser-induced fluorescence (LIF) study is first recommended to identify potential areas of remaining subsurface free product which would help identify appropriate recovery well locations. Additionally, the AS/SVE system should be shut down for approximately one week to allow water levels to reach equilibrium. The SVE wells should then be gauged for potential free product that may exist but has not been identified during regular groundwater monitoring events;  pulsing the AS/SVE system on and off over time or between zones to enhance recovery in specific areas;  installation of oxygen releasing socks or an in-situ oxygen curtain in areas of continued impact to aid in bioremediation. Additionally, continued general maintenance of the system is recommended to be conducted once per month. Potential adjustments to the existing system will be evaluated (e.g. vacuum or flow adjustments) to enhance recovery. Influent air samples are recommended to be collected from the SVE system on a Former Tilley’s Superette January 30, 2018 Monitoring Report Page 8 quarterly basis during site visits. Groundwater samples are recommended to be collected from site monitoring wells on a semi-annual basis. Former Tilley’s Superette January 30, 2018 Monitoring Report Page 9 5.0 REPORT LIMITATIONS This investigation is intended to be a non-biased assessment of on-site environmental conditions proximate to the location of the former and/or current UST system. Subsurface investigative and remedial methodologies were performed in general accordance with applicable state and federal regulatory requirements. The information presented in this report is based upon site-specific observations, generally accepted geological and environmental consulting practices, and analytical results for environmental samples collected at the time of the field investigation was performed. The data presented in this report are believed to represent subsurface conditions at the facility; however, data may not be completely representative of subsurface conditions at every location. ATC assumes no liability arising from environmental impact to, or from, the site, regardless of the date of impact occurrence or findings.

Depth to groundwater measurements were obtained by lowering the device into the well until it indicated that the water surface had been encountered, at which point a measurement was taken at the top of the riser pipe or top of casing. Measurements were recorded to the nearest 0.01 foot. 24BGroundwater Sampling Groundwater samples were collected using a new, dedicated plastic bailer or pre-decontaminated submersible pump with associated new tubing. Before obtaining a sample, a minimum of three well volumes of groundwater were evacuated to ensure collection of a sample representative of the in-situ groundwater conditions. A sample was collected using a dedicated bailer, or via outflow for the tubing connected to the submersible pump and transferred to containers supplied by the laboratory, and placed in an ice-filled cooler. Chain-of-custody forms were completed and accompanied the samples to the laboratory. The submersible pump system was decontaminated between wells using alconox, deionized water, and alcohol. 25BChemical Analysis Chemical analyses were performed by Shealy Environmental Services, Inc. in Columbia, South Carolina. Extractions and analyses were performed in accordance with standard Environmental Protection Agency (EPA) methodology. The groundwater samples were analyzed for volatile organic compounds by EPA Method 602 including BTEX (benzene, toluene, ethylbenzene, and total xylenes), methyl-tert butyl ether (MTBE), and isopropyl ether (IPE) and for ethylene dibromide (EDB) by EPA Method 504.1.

The sample receiving date is documented in the header information associated with each sample. All results listed in this report relate only to the samples that are contained within this report. Sample receipt,sample analysis,and data review have been performed in accordance with the most current approved NELAC standards,the Shealy Environmental Services,Inc.("Shealy")Quality Assurance Management Plan (QAMP),standard operating procedures (SOPs),and Shealy policies.Any exceptions to the NELAC standards,the QAMP,SOPs or policies are qualified on the results page or discussed below. If you have any questions regarding this report please contact the Shealy Project Manager listed on the cover page. Volatiles The continuing calibration verification (CCV)for samples -002,-003,-004,-005 -006,-007 and -008 had IPE and MTBE recovered above the acceptance limits due to confirmed matrix interference. Sample -004 had surrogates recovered above the acceptance limits.This reflects a high bias for compounds associated with these surrogates.There were no detections for these compounds in the sample;therefore,there is no impact on data quality and no corrective action is required. EDB/DBCP Due to high detections for target compounds,samples -001,-002,-003 and -005 were diluted 5000x,2000x,10x and 5x,respectively.As a result,the associated surrogates were recovered outside of the acceptance limits.No corrective action was required,as dilutions of 5x and greater impact recovery accuracy.

(ATC) to prepare a Monitoring Report for the project site located at 1710 Union Grove Road in Lenoir, Caldwell County, North Carolina. Figure 1 shows the site and vicinity on part of a United States Geological Survey (USGS) site topographic map. Figure 2 is a site map which shows site features and monitoring well locations. This report documents the results of a groundwater monitoring event conducted in February 2018. Groundwater impact at the site has historically been identified at concentrations exceeding Gross Contamination Levels (GCLs). Generally decreasing trends have been observed over time. According to recent groundwater analytical results, contaminant concentrations appear to be stabilizing or decreasing overall. Petroleum hydrocarbons were detected above the associated 15A NCAC 2L.0202 standards (2L standards) in five of the eight sampled site monitoring wells. Benzene was reported in well MW-2 above its respective 2L standard, and ethylene dibromide (EDB) was reported in wells MW-1 and MW-2 at concentrations above their respective GCLs in February 2018. Free product has historically been identified at the site with a maximum thickness of 0.78 feet in well MW-2. Free product was not identified in site monitoring wells in February 2018, but a sheen was observed in well MW-2. Based on vicinity water supply wells, historical free product, and groundwater impact in on-site wells, the risk classification for the site has been designated as “High” and ranked H155D by the North Carolina Department of Environmental Quality (NCDEQ). Therefore, groundwater contamination must be remediated to concentrations which are equal to or less than the associated 2L standards. As outlined in the August 2009 Corrective Action Plan (CAP), air sparge and soil vapor extraction (AS/SVE) technologies were the chosen corrective actions for this site based on site conditions and technical considerations. The AS/SVE wells were installed from November 14 to November 22, 2011. The system components were delivered and installed from December 2011 to March 2012. The system was started on April 24, 2012. Based on laboratory analytical results from quarterly effluent air sampling, approximately 3,437 pounds of total BTEX have been recovered by the SVE system since startup. Based on the results of the February 19, 2018, monitoring event, the following site conditions existed: Former Tilley’s Superette May 17, 2018 Monitoring Report Page 2  One or more volatile organic compounds (VOCs) using EPA Method 602 were reported above 2L standards in wells MW-1, MW-2, MW-3, MW-9, and MW-12, and the benzene concentrations in well MW-2 exceeded the GCL.  Concentrations of EDB reported using EPA Method 504.1 exceeded the 2L standard in samples collected from wells MW-1, MW-2, MW-3, and MW-9. The EDB concentrations in wells MW-1 and MW-2 exceeded the GCL.  The direction of groundwater flow is to the south. Former Tilley’s Superette May 17, 2018 Monitoring Report Page 3 2.0 SUPPORTING INFORMATION AND CAP IMPLEMENTATION An underground storage tank (UST) system consisting of six tanks was formerly located on-site and was operated by Cary Oil from April 1, 2005, until October 2006 when the UST system was removed. During UST removals, soil impact was identified and led to assessment requests from the North Carolina Department of Environment and Natural Resources (NCDENR; currently the NCDEQ). Residential properties and rural land surround the property. The subject property is owned by Warren Tilley and includes one building that operates as Narrow Way Baptist Church. Between the late 1950s and August 2006, a grocery store and gas station with a barber shop operated at the site. Site history including on-site UST system information is summarized in Table 1. A site plan that indicates monitoring well locations and other site features is provided as Figure 2. The surface water bodies closest to the site are an unnamed pond and a tributary of Stafford Creek, which are located approximately 2,000 feet south of the site. Surface cover at the site consists mostly of grass, except in front of the building and to the eastern side of the building which is covered with asphalt and gravel. The site lies in the Inner Piedmont in an area characterized by inter-fingered biotite gneiss, biotite schist, and mica schist with some other minor rock types that are heavily metamorphosed and structurally complex. The shallow subsurface contains overburden of soil, saprolite, and partially weathered rock (PWR) that derive from in-place weathering. Depth to rock ranges from ground surface at occasional outcrops to depths of up to 100 feet in areas of easily weathered rock. The soil type encountered during installation of the remediation wells was described as red/brown/tan silt and clay with mica and PWR. Granitic/dioritic gneiss was encountered beginning at depths of approximately 55 to 80 feet below land surface (bls) across the site. Depth to groundwater in the site monitoring wells ranged from approximately 34 to 38 feet below top of casing (TOC) during the February 2018 groundwater sampling event. Based on the recent groundwater level measurements and calculation of groundwater elevations, groundwater flows south across the site. Public water, supplied by Baton Water Corporation, is provided to the site and surrounding area. Eighteen (18) supply wells have been identified within approximately 1,500 feet of the site. One private well (PW-7) has historically been reported as being used for potable water and is located approximately 415 feet sidegradient of the site. ATC recently contacted Baton Water Corporation and water service is now Former Tilley’s Superette May 17, 2018 Monitoring Report Page 4 provided to this property located at 1679 Union Grove Road. Two other wells are being used for irrigation and are located approximately 750 feet and 875 feet sidegradient of the site, respectively. Potable water is provided to these properties by Baton Water Corporation. Water supply well information for the area is summarized in Table 3, and supply well locations relative to the source area are depicted on Figure 3. Between 2006 and 2012, site assessment, Aggressive Fluid/Vapor Recovery (AFVR) events for free product recovery, and a CAP with pilot testing were conducted related to the Tilley’s release. Free product recovery efforts in the form of AFVR and Mobile Multi-Phase Extraction (MMPE) events, conducted between 2008 and 2012, recovered approximately 399.98 gallons of petroleum as vapor, 36 gallons of liquid product, and 15,622 gallons of petroleum-contact water. Historical free product recovery information is summarized in Table 7. The site monitoring wells did not indicate free product during post-AFVR gauging conducted on June 6, 2012, and during subsequent groundwater sampling events conducted since August 2012. However, a sheen was observed in groundwater from wells MW-1 through MW-3 during an August 2017 monitoring event. Based on results of the CAP and pilot testing, ATC found that AS and SVE technologies appeared to be the most feasible and cost effective remedial options for reducing groundwater contaminant concentrations associated with the site (Incident No. 28466). With the exception of four SVE wells installed as part of the pilot test in 2009, the system was installed during the period of November 2011 through March 2012. The air sparge system consists of 16 air sparge wells, a rotary claw air compressor, and schedule 80 PVC piping for transferring compressed air from the remediation system to the air sparge wells. The vapor extraction system consists of 14 vapor extraction wells, a regenerative vacuum blower, and schedule 40 PVC piping for transferring extracted vapors from the vapor extraction wells to the remediation system. The system was started on April 24, 2012. Air sparge well AS-2 was started on June 20, 2012, after free product was sufficiently removed from the area. Former Tilley’s Superette May 17, 2018 Monitoring Report Page 5 3.0 GROUNDWATER INVESTIGATION 3.1 Fluid Measurements and Free Product Conditions On February 19, 2018 an oil/water interface probe was used to check for the presence of free product and measure static water levels at monitoring wells MW-1, MW-2, MW-3, MW-5D, MW-9, MW-12, MW-16D, and MW-18. The groundwater elevations were determined in reference to the surveyed top-of-casing elevations. Relevant field methods are summarized in Appendix A. Groundwater elevations were calculated based on the February 2018 gauging data, and a summary of historical groundwater elevation data is included in Table 4. A groundwater elevation contour map, based on the February 2018 static water level data, is included as Figure 4. The groundwater potentiometric surface indicates that groundwater at the site generally flows towards the south. Historically, free product has been detected in monitoring wells MW-2, MW-3, and vapor extraction wells VE-1, VE-2, and VE-3. During the February 2018 monitoring activities, free product was not identified in the site monitoring wells but a sheen was observed in groundwater in well MW-2. 3.2 Groundwater Sampling Groundwater samples were obtained from monitoring wells MW-1, MW-2, MW-3, MW-5D, MW-9, MW- 12, MW-16D, and MW-18 on February 19, 2018. Prior to sampling, each well was purged of three standing water columns, or until the well was purged dry. Samples were then collected with new disposable bailers and poured directly into laboratory-provided containers with appropriate preservatives. The samples were placed in a chilled cooler and submitted to North Carolina-accredited Shealy Environmental Services, Inc. of Columbia, South Carolina, using proper chain-of-custody procedures for laboratory analyses. Groundwater samples from the monitoring wells were analyzed for volatile organic compounds by EPA Method 602 including BTEX (benzene, toluene, ethylbenzene, and total xylenes), methyl-tert butyl ether (MTBE), and isopropyl ether (IPE) and by EPA Method 504.1 for EDB. According to the analytical results, concentrations of petroleum hydrocarbons were detected above the associated 2L standards in monitoring wells MW-1, MW-2, MW-3, MW-9, and MW-12. Specifically, laboratory results indicated the following: Former Tilley’s Superette May 17, 2018 Monitoring Report Page 6  One or more volatile organic compounds (VOCs) using EPA Method 602 were reported above 2L standards in wells MW-1, MW-2, MW-3, MW-9, and MW-12, and the benzene concentrations detected in well MW-2 exceeded its respective GCL.  Concentrations of EDB reported using EPA Method 504.1 exceeded the 2L standard in samples collected from wells MW-1, MW-2, MW-3, and MW-9. The EDB concentrations in wells MW-1 and MW-2 exceeded the GCL. Based on these results, groundwater contamination is generally located along the south side of the subject site in the vicinity of, and downgradient from, the former UST system. Groundwater contaminant concentrations generally decreased in monitoring well MW-1, and remained stable in wells MW-3, MW-9, and MW-12 between the August 2017 and February 2018 sampling events. Contaminant concentrations in well MW-2 increased significantly between August 2017 and February 2018. Groundwater analytical results obtained in February 2018 are summarized in Table 5. Isoconcentration maps for dissolved benzene, toluene, ethylbenzene, total xylenes, MTBE, and EDB are depicted as Figure 5 through Figure 10, respectively. A historical summary of groundwater analytical results is provided in Table 6. Copies of the February 2018 laboratory analytical report and chain-of-custody forms are included in Appendix B. Former Tilley’s Superette May 17, 2018 Monitoring Report Page 7 4.0 CONCLUSIONS AND RECOMMENDATIONS A groundwater sampling event was conducted at the Former Tilley’s Superette on February 19, 2018. Impact to groundwater in the source area continues to exceed the 2L Standards, and benzene in well MW- 2 exceeds the GCL standard. EDB concentrations in wells MW-1 and MW-2 exceed their respective GCLs. Groundwater contaminant concentrations generally decreased in monitoring well MW-1 but were generally stable in wells MW-3, MW-9, and MW-12 between August 2017 and February 2018. Contaminant concentrations in well MW-2 increased significantly between August 2017 and February 2018. A review of historical soil contaminant concentrations does not indicate sufficiently elevated sorbed contamination to indicate a continued source of impact to groundwater. However, it is possible there is unidentified remaining soil impact or product in the subsurface that is resulting in the elevated dissolved contaminant levels. ATC has previously recommended system enhancements to potentially increase efficiency, such as replacement of the source area 2” SVE wells with 4” SVE wells and a sparge test to identify if using shallower sparge wells is an option for remediating shallow aquifer groundwater. The trust fund will not cover the costs for these proposed system enhancements. Alternative options include:  installation of 4” diameter recovery wells for AFVR events. The AFVR events could be conducted with sparge enhancement using impacted monitoring wells (MW-1 through MW-3, depending on recovery well locations);  if recovery events are conducted, a laser-induced fluorescence (LIF) study is first recommended to identify potential areas of remaining subsurface free product which would help identify appropriate recovery well locations. Additionally, the AS/SVE system should be shut down for approximately one week to allow water levels to reach equilibrium. The SVE wells should then be gauged for potential free product that may exist but has not been identified during regular groundwater monitoring events;  pulsing the AS/SVE system on and off over time or between zones to enhance recovery in specific areas;  installation of oxygen releasing socks or an in-situ oxygen curtain in areas of continued impact to aid in bioremediation. Additionally, continued general maintenance of the system is recommended to be conducted once per month. Potential adjustments to the existing system will be evaluated (e.g. vacuum or flow adjustments) Former Tilley’s Superette May 17, 2018 Monitoring Report Page 8 to enhance recovery. Influent air samples are recommended to be collected from the SVE system on a quarterly basis during site visits. Groundwater samples are recommended to be collected from site monitoring wells on a semi-annual basis.

Depth to groundwater measurements were obtained by lowering the device into the well until it indicated that the water surface had been encountered, at which point a measurement was taken at the top of the riser pipe or top of casing. Measurements were recorded to the nearest 0.01 foot. 24BGroundwater Sampling Groundwater samples were collected using a new, dedicated plastic bailer or pre-decontaminated submersible pump with associated new tubing. Before obtaining a sample, a minimum of three well volumes of groundwater were evacuated to ensure collection of a sample representative of the in-situ groundwater conditions. A sample was collected using a dedicated bailer, or via outflow for the tubing connected to the submersible pump and transferred to containers supplied by the laboratory, and placed in an ice-filled cooler. Chain-of-custody forms were completed and accompanied the samples to the laboratory. The submersible pump system was decontaminated between wells using alconox, deionized water, and alcohol. 25BChemical Analysis Chemical analyses were performed by Shealy Environmental Services, Inc. in Columbia, South Carolina. Extractions and analyses were performed in accordance with standard Environmental Protection Agency (EPA) methodology. The groundwater samples were analyzed for volatile organic compounds by EPA Method 602 including BTEX (benzene, toluene, ethylbenzene, and total xylenes), methyl-tert butyl ether (MTBE), and isopropyl ether (IPE) and for ethylene dibromide (EDB) by EPA Method 504.1.
