(ATC) has completed a Groundwater Monitoring Report for the Jeff’s Grocery site. This report documents groundwater sampling activities conducted at the site in November 2019. The activities were performed based on an October 17, 2019 Task Authorization (TA-04) by the Trust Fund Branch of the Underground Storage Tank (UST) Section, Division of Waste Management, North Carolina Department of Environmental Quality (NCDEQ). The work is being performed as part of State Lead Contract #N17004 between NCDEQ and ATC. The former Jeff’s Grocery site is located at 2996 NC Highway 268 in Pinnacle, Stokes County, North Carolina. The site is developed with one single-story brick building and is currently used as a convenience store. Three monitoring wells are located at the site. Nine potable water supply wells are located within 1,000 feet of the site. Municipal water is not available to the site or vicinity. On November 19, 2019, ATC personnel mobilized to the site to supervise the installation of two (2) monitoring wells (MW-2 and MW-3). On November 20, 2019, ATC personnel mobilized to the site to collect a groundwater sample from MW-1, MW-2, MW-3, and water supply wells WSW-1, WSW-3, WSW-4, and WSW-5. Laboratory results indicate methyl tert-butyl ether (MTBE) above the North Carolina Groundwater Quality Standards (2L Standards) but below the Gross Contaminant Levels (GCLs) in MW-1. None of the samples collected from the water supply wells contained concentrations exceeding the laboratory detection limits. Based on the sampling results collected to date, the plume is limited to the area around MW-1. The site is not a candidate for closure due to the presence of potable water supply wells within 1,000 feet of the site, most notably WSW-1 located on the source property. ATC recommends groundwater and water supply well sampling on an annual basis. Groundwater Monitoring Report February 7, 2020 Jeff’s Grocery (Incident #37041) ATC Project No. SLP3704104 3 3.0 SITE DESCRIPTION 3.1 Site Characterization The Jeff’s Grocery site formerly operated as a convenience store and petroleum retail facility. Currently, the site is used as Cornerstone Market, a convenience store. The former UST system consisted of two 3,000-gallon gasoline USTs located at the southwestern corner of the onsite building. The USTs were in operation from 1984 until March 2008 when they were removed from the site. Three (3) monitoring wells (MW-1 through MW-3) are associated with the site. Properties surrounding the site are used for residential and agricultural purposes or are undeveloped. A site topographic map is included as Figure 1. Nine water supply wells are located within 1,000 feet of the site. Water supply well ownership information is included in Table 1 and a site map depicting monitoring well locations and other pertinent site features is included as Figure 2. A potential receptor map is included as Figure 3. 3.2 Site Background In August 2007, ECS Carolina, LLP, submitted a Report of Environmental Services documenting soil and groundwater assessment activities performed at the site at the request of property owner, Mr. Chad Lynch. During the assessment, soil borings GP-1 through GP-10 were advanced around the UST system and a groundwater sample was collected directly downgradient of the USTs. Soil samples collected from boring GP-7 through GP-10 contained levels of total petroleum hydrocarbons (TPH) gasoline range organics (GRO) and/or diesel range organics (DRO) above the NCDEQ Action Level. The groundwater sample did not contain petroleum compounds above laboratory detection limit. On March 26, 2008, Geological & Environmental Services submitted a UST Closure Report for the site. During the closure, two 3,000-gallon gasoline USTs were removed from the site. Soil samples collected from beneath the USTs and dispenser did not contain petroleum hydrocarbons above the respective standards; however, the soil directly beneath the product lines indicated impact. Over Groundwater Monitoring Report February 7, 2020 Jeff’s Grocery (Incident #37041) ATC Project No. SLP3704104 4 excavation was performed in the vicinity of the product lines. Following over excavation activities, samples were collected from beneath the product lines at approximately 8 feet below ground surface (bgs) and contained soil impacts above Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs). Approximately 50 tons of soil was removed from the site during the UST Closure. On April 29, 2011, Terraquest Environmental Consultants, P.C. submitted a Receptor Survey and Water Supply Well Sampling Report. Based on the results of the receptor survey, nine active water supply wells are located within 1,000 feet of the site. Water supply wells WSW-1 through WSW-6 were sampled in March and April 2011. Lead was detected in water supply wells WSW-5 and WSW-6 above the 2L Standard. Based on a 2-step, first draw method of sampling, it was determined the source of lead for WSW-5 was from the home supply line while the source of lead for WSW-6 was the groundwater. No other compounds were detected in the samples. On June 18, 2015, ATC submitted a Letter Report documenting a water supply well sampling event. During the event, samples were collected from water supply wells WSW-1, WSW-3, WSW-5, and WSW-6. Chloromethane was detected in water supply well WSW-6 at a concentration of 0.36 micrograms per liter (g/L) which is below the laboratory reporting limit as well as the 2L Standard. No other compounds were detected is the water supply well samples. Water supply well information is included in Table 1. ATC recommended completion of a soil assessment around historical soil borings GP-7, GP-8, GP-9, and GP-10 to determine current soil impacts at the site. On October 8, 2015, ATC submitted a Soil Assessment Report documenting the collection of four soil samples (SB-1 through SB-4). The soil borings were placed in the vicinity of former soil borings GP-7 through GP-10 to determine current soil concentrations at the site. Based on the laboratory results, it appears compounds are attenuating in the soil. ATC recommended installing one monitoring well in the vicinity of the former product lines to determine impacts to groundwater. Groundwater Monitoring Report February 7, 2020 Jeff’s Grocery (Incident #37041) ATC Project No. SLP3704104 5 On June 3, 2016, ATC submitted a Groundwater Monitoring Report documenting the installation and sampling of monitoring well MW-1. The sample collected from MW-1 indicated MTBE above the 2L Standard. ATC recommended installing two additional monitoring wells to determine groundwater flow direction, placement of O-SOX in monitoring well MW-1, and performing a water supply well sampling event. On August 27, 2016, ATC submitted a Water Supply Well Sampling Letter Report documenting the sampling of water supply wells WSW-1, WSW-3, WSW-4, and WSW-5. No compounds were detected. The report also documented the placement of O-SOX in monitoring well MW-1. ATC recommended sampling monitoring well MW-1 in January 2017. On May 11, 2017, ATC submitted a Groundwater Sampling Letter Report documenting the sampling of monitoring well MW-1 and water supply well WSW-1. Monitoring well MW-1 indicated MTBE and naphthalene above the 2L Standards. No compounds were detected in water supply well WSW-1. ATC recommended placement of O-SOX in monitoring well MW-1 with sampling of MW-1 three months later. On May 14, 2018, ATC submitted a Groundwater Sampling Letter Report documenting the sampling of water supply wells WSW-1, WSW-3, WSW-4, and WSW-5. Monitoring well MW- 1 indicated MTBE above the 2L Standard. No compounds were detected in water supply wells WSW-1, WSW-3, WSW-4, or WSW-5. ATC recommended placement of O-SOX in monitoring well MW-1 with sampling of MW-1 three months later. On June 25, 2019, ATC submitted a Groundwater Sampling Letter Report documenting the sampling of water supply wells WSW-1, WSW-3, WSW-4, and WSW-5. Monitoring well MW- 1 indicated MTBE above the 2L Standard. No compounds were detected in the water supply wells. ATC recommended installing and sampling two (2) additional monitoring wells at the site to delineate groundwater impact and to determine groundwater flow direction. Groundwater Monitoring Report February 7, 2020 Jeff’s Grocery (Incident #37041) ATC Project No. SLP3704104 6 This report documents the installation of monitoring wells MW-2 and MW-3 on November 19, 2019 and the subsequent, groundwater and water supply well sampling event on November 20, 2019. 4.0 MONITORING WELL INSTALLATION As authorized in TA-04, ATC supervised the installation of monitoring wells MW-2 and MW-3 on November 19, 2019. Monitoring well MW-2 is located in the paved area off the southwestern corner of the site building. Monitoring well MW-3 is located in the paved/gravel area in the east/southeastern portion of the site. The purpose of these wells was to determine the extent of groundwater impact and to determine the direction of groundwater flow. Geologic Exploration, Inc. installed the monitoring wells to 35 feet below ground surface (bgs) with 15 feet of 0.010- inch slotted screen via hand auger and air drilling techniques. Lithology encountered during the monitoring well installation consisted mainly of silt. Field notes documenting well installation activities are included as Appendix A. Soil boring logs and well construction records are included as Appendix B. A site map identifying the newly installed monitoring well is presented as Figure 2. 5.0 GROUNDWATER ASSESSMENT ACTIVITIES 5.1 Groundwater Levels On November 19, 2019, ATC surveyed monitoring wells MW-1, MW-2, and MW-3 using MW-1 as a benchmark. On November 20, 2019, groundwater level measurements and samples were collected from monitoring wells MW-1, MW-2, and MW-3. Monitoring well construction details and groundwater elevation data are summarized in Table 2. Light non-aqueous phase liquid (LNAPL) was not observed in any of the monitoring wells that were gauged. Depth to groundwater measurements ranged from 26.73 feet bgs in MW-2 to 32.02 feet bgs in MW-3. A groundwater elevation contour map generated using the November 2019 groundwater elevation data is included as Figure 4. This figure indicates that the direction of groundwater flow at the site is to the east. Field notes from the sampling event are included in Appendix A. Groundwater Monitoring Report February 7, 2020 Jeff’s Grocery (Incident #37041) ATC Project No. SLP3704104 7 5.2 Groundwater Quality On November 20, 2019, groundwater samples were collected from monitoring wells MW-1, MW-2, and MW-3. Samples were collected in laboratory-approved containers, packed in ice and delivered under chain-of-custody protocol to SGS North America Inc., in Scott, Louisiana for analyses. Groundwater samples were analyzed for volatile organic compounds (VOCs) by Environmental Protection Agency (EPA) Method 6200B. The analytical results were compared to the 2L Standards and GCLs. MTBE was detected in MW-1 at 67.4 µg/l, exceeding the 2L Standard, but below the GCL. A comparison of the current analytical results (November 20, 2019) to the results of the previous sampling event (May 24, 2019) indicates a slight decrease in MTBE concentrations in MW-1. Monitoring well analytical results are included in Table 3. Natural attenuation parameters are summarized in Table 4. A MTBE isoconcentration contour map is included as Figure 5. The laboratory analytical report and chain-of-custody forms are included in Appendix C. As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of the laboratory report was conducted. During the review, it was concluded that samples were received by the laboratory in acceptable condition and properly preserved. Samples were analyzed within the correct holding times, and the chain of custody was properly completed by all parties. The laboratory QC report shows an internal blank was analyzed for each method that was used for the original samples. The laboratory fortified blank (LFB) and laboratory control sample (LCS) data results were also provided for each analytical method. Refer to the laboratory report in Appendix C for details regarding QA results for the laboratory samples and any noted exceptions. Overall, ATC concludes that the laboratory results are usable and any exceptions do not significantly impact the conclusions presented in this report. Groundwater Monitoring Report February 7, 2020 Jeff’s Grocery (Incident #37041) ATC Project No. SLP3704104 8 5.3 Water Supply Wells Nine active water supply wells are located within 1,000 feet of the site. Municipal water is not available in the vicinity of the site. Table 1 presents the water supply well ownership information and Figure 3 depicts the water supply well locations. ATC collected groundwater samples from WSW-1, WSW-3, WSW-4, and WSW-5 during the November 20, 2019 sampling event. The owner of WSW-2 indicated there is no water supply well at this location; however, he does plan on installing a water supply well in the future. The owner of WSW-6 refused to grant permission to collect a sample. The samples were collected in laboratory-approved containers, packed in ice and delivered under chain-of-custody protocol to SGS for analyses. The samples were analyzed for VOCs by EPA Method 6200B. None of the samples contained concentrations exceeding the laboratory detection limits. The water supply well analytical results are summarized in Table 5. The QA and QC measures and conditions applicable to the monitoring well sampling also apply to the water supply well sampling. The laboratory analytical report and chain-of-custody forms are included in Appendix C. 6.0 CONCLUSIONS AND RECOMMENDATIONS On behalf of the Trust Fund Branch of the UST Section, ATC completed a Groundwater Monitoring Report documenting the November 2019 assessment and groundwater sampling activities at the Jeff’s Grocery property located at 2996 NC Highway 268 in Pinnacle, Stokes County, North Carolina. Groundwater samples were collected from monitoring wells MW-1, MW-2, and MW-3 and water supply wells WSW-1, WSW-3, WSW-4, and WSW-5. Results from the monitoring event indicated MTBE above 2L Standard but, below GCL in monitoring well MW-1. None of the samples collected from the water supply wells contained concentrations exceeding the laboratory detection limits. Groundwater Monitoring Report February 7, 2020 Jeff’s Grocery (Incident #37041) ATC Project No. SLP3704104 9 The site is not a candidate for closure due to the presence of potable water supply wells within 1,000 feet of the site, most notably WSW-1 located on the source property. ATC recommends groundwater and water supply well sampling on an annual basis.
