The facility is located at the intersection of North Ellis Avenue (HWY 301) and West Barrington Street in Dunn, North Carolina. The site is an active gasoline retail and convenience store facility that is currently owned by Al-Haj Ibrahim Mohamed Hafdalla (Liberty Mart #1). The site location is shown on Figure 1, a portion of the USGS Dunn, North Carolina 7.5 minute Quadrangle Map. Figure 2 is a site plan map depicting the locations of site monitoring wells and pertinent site features including known utilities. 1.2 RELEASE DESCRIPTION On March 29, 1995, phase separated hydrocarbons (PSH) were discovered in a utility trench that was dug for the repair of a sewer line located adjacent to the site. Upon the discovery of the PSH, UST system upgrades began on April 10, 1995 that included the replacement of product lines, dispensers and UST pumps. During the product line installation, approximately 90 gallons of PSH was removed from the trench. A precision tightness test was then performed on the USTs. A kerosene UST failed the test and all associated dispensers, piping, pumps, and the UST was removed on April 27, 1995 Following the release detection, multiple site investigative phases were performed including a Comprehensive Site Assessment (CSA) in October 1995 and a Corrective Action Plan (CAP) in April 1996. The CAP recommended the installation of a pump and treat system with soil vapor extraction (SVE). System recovery wells and associated piping were installed as proposed in the CAP; however, the remediation equipment was not installed, as directed groundwater remediation operations were suspended by the North Carolina Department of Environmental Quality – Division of Waste Management (NCDEQ-DWM). In 2002, T-Mart was notified by the DWM to proceed with groundwater remediation activities. In response to the notification, EMS prepared a revised CAP that proposed an alternative remediation strategy that would consist of an air sparge (AS) and soil vapor extraction (SVE) system enclosed in a trailer. Existing monitoring wells and recovery wells were proposed to be used for the AS/SVE system. The system was subsequently installed in 2003; however, it only operated for approximately three months before the DWM suspended directed remediation activities due to North Carolina Session Law 2003-352 that took effect on October 27, 2003. 2 In 2010, T-Mart was directed by the NCDEQ-DWM to initiate PSH removal. As part of the continued assessment and remedial activities; groundwater monitoring and sampling, additional groundwater delineation well installations, Aggressive Fluid Vapor Recovery (AFVR), and Mobile Multi-Phase Extraction (MMPE) events have been performed at the site since December 2011. No active remediation of impacted groundwater was performed this period. Secondary source soil excavation activities were performed in the second semiannual period of 2021 between November 1 through 3, 2021. A total of 542.32 tons of impacted soils (22 loads) was excavated and direct loaded into dump trucks for off-site disposal at Carlisle Farms, Inc., a NC certified land farm dedicated land farm located in Autryville, North Carolina. 1.3 POTENTIAL RECEPTORS No potable water supply wells were identified within a quarter mile of the site in a receptor survey that was conducted for the CSA in 1996. Potable water is supplied to the site and the site vicinity by the City of Dunn. No surface water bodies have been found to be present within 500 feet of the site. Buried utility lines are present on and adjacent to the site. Eight inch water lines which supply the site vicinity run beneath North Ellis Avenue and West Barrington Street. Sanitary sewer lines also run along Ellis and Barrington Streets. Storm sewer lines which run parallel to the southeastern T-Mart property boundary appear to intersect the dissolved hydrocarbon plume. The storm sewer discharges into Stoney Creek, south of an unnamed pond approximately 3,000 feet southeast of the site. The approximate locations of site utilities are shown on Figure 2. 1.4 SUMMARY OF SITE ACTIVITIES PERFORMED THIS PERIOD Work was performed at the site under a pre-approval/claim task authorization received from the NCDEQ and attached in Appendix A. The following work was performed under TA # 16885-37 and is reported on herein. • Groundwater Monitoring and Sampling – 6/02/2023. 3 2.0 SITE ASSESSMENT INFORMATION 2.1 GROUNDWATER MONITORING AND SAMPLING ACTIVITIES Groundwater monitoring and sampling activities were performed from select site monitoring wells on June 2, 2023. Monitoring wells MW-1, MW-15, MW-23, MW-26, MW-27R, MW-28R, RW-2 (MW-3), RW-5, and RW-6 were sampled this period. Phase Separated Hydrocarbons (PSH) were not observed to be present in any well this period. At the direction of the NCDEQ, monitoring wells that have historically shown low to non-detectable concentrations of dissolved phase petroleum hydrocarbons, including RW-1 (MW-2), MW-5, MW-6, MW-7, MW-9, RW-4 (MW-10), MW-11, MW-12, MW-16, MW-21D, MW-22, MW-24, PW-1 and PW-2, were not sampled this semi-annual period. MW-14 has been observed as destroyed; MW-8, MW-17, and MW-25 have been lost. MW- 4, MW-18, and MW-19 have been formally abandoned. 2.2 FLUID LEVEL MEASUREMENT The depth to water (DTW) from the top of casing (TOC) was measured in each sampled monitoring well on June 2, 2023. The measurements were conducted using a clean oil-water interface probe (IFP). The measurements were subtracted from the relative elevations of TOC to estimate the groundwater surface elevation. Well construction information is provided in Table 1. A summary of the depth to water (DTW) measurements is included in Table 2. PSH was not measured this period. Shallow groundwater was present below the top of casing at depths that ranged from 2.22 feet in MW-15 to 4.38 feet in MW-28R. The attached Figure 3 was prepared from the monitoring data and indicates that groundwater flow is oriented toward the southeast at a hydraulic gradient of 0.01 feet/feet between MW-3 (RW-2) and MW-15. 2.3 MONITORING WELL SAMPLING Groundwater samples were collected from each monitoring well using dedicated polyethylene bailers and new nylon line. Samples were collected from the wells and poured into laboratory supplied sample containers that contained preservatives, if required for the analysis. The samples were placed into ice chilled coolers and transported to Environmental Conservation Laboratories, Inc. (ENCO), a NC certified laboratory (Lab Certification #591) located in Cary, North Carolina. The samples were submitted to the laboratory for analysis using the following test methods: • Volatile organic compounds by EPA Method 6200B – 6/02/2023 event 4 2.4 GROUNDWATER SAMPLING RESULTS An analyses by EPA Method 6200B revealed detectable concentrations of multiple targeted compounds with concentrations above the North Carolina Administrative Code (NCAC) 2L Groundwater Standards (GWS). Of the detected compounds, none were reported above the respective Gross Contaminant Level (GCL) this period. No further exceedances of the GCLs were reported by the analytical laboratory. EPA Method 6200B and historical lead groundwater sampling result summaries are attached in Table 3. Complete laboratory analytical reports with chain-of- custody documentation are included in Appendix B. Analysis by EPA Method 6200B this period inadvertently did not include an evaluation for the presence of Ethanol and Oxygenates for the samples collected on June 2, 2023. Historical analytical results are summarized on Table 4. Historical analytical results for Massachusetts Department of Environmental Protection (MADEP) Extractable Petroleum Hydrocarbons (EPH) and Volatile Petroleum Hydrocarbons (VPH) have been summarized in Table 5. 2.5 CURRENT PLUME SIZE - LOCATION AND PROXIMITY TO NEAREST POTENTIAL RECEPTOR Isoconcentration maps were prepared for selected compounds detected in the groundwater samples collected on June 2, 2023. Figures 4 through 8 depict the approximate horizontal distribution of benzene, toluene, ethylbenzene, xylenes (total), and MTBE respectively. The compounds are contoured to the NCAC 2L Groundwater Standards. As shown on the maps, the plume of dissolved phase hydrocarbons is situated on the site and may have migrated offsite towards the southeast (MW-23 – Figure 4 and Figure 8). Historically, PSH has been detected onsite in MW-1, MW-2 (RW-1), MW-3, (RW-2), RW-3, and RW-5. This period PSH was not detected in any well. Historically, monitoring wells with the highest dissolved phase concentrations include MW-1, MW-3 (RW-2), MW-15, RW-5 and RW-6. Concentration versus time plots of Total BTEX and Benzene concentrations with superimposed depth to water have been prepared to graphically illustrate dissolved phase Total BTEX and Benzene plume concentration variance in the wells which historically exhibited the highest dissolved phase concentrations. The graphical illustrations are included as Appendix C. Review of the graphs indicate decreases of Total BTEX concentration with periods of intermittent rebound. However Total BTEX concentrations show an overall declining trend since groundwater cleanup was initiated. MW-26, MW-27R, and MW-28R also have exhibited high dissolved phase concentrations since their installation. However, there is insufficient data to prepare meaningful concentration versus time plots for these wells at this time. 5 3.0 FREE PRODUCT RECOVERY 3.1 HISTORICAL FREE PRODUCT RECOVERY PSH recovery began at the site during initial abatement activities in 1995. Approximately 850 gallons of PSH was removed through vacuum extraction, hand bailing and other methods. In 2010, T-Mart was directed by the NCDEQ-DWM to initiate additional PSH removal. As part of the continued PSH remedial activities, installation of down well oil only wicks, AFVR, and MMPE has been performed at the site. Down well wicks have been calculated to have recovered approximately 4.683 gallons of PSH. A total of 36 AFVR events have been conducted to date resulting in the cumulative removal of an additional 208.47 gallons of liquid and vapor emission PSH. A total of 2 MMPE events have been conducted to date resulting in the cumulative removal of an additional 238.45 gallons of liquid and vapor emission PSH. The cumulative total, including this period, is 1,302.39 gallons of liquid and vapor emission PSH. A current and historical free product recovery summary has been included as Table 6. 4.0 SOIL QUALITY 4.1 HISTORICAL SOIL QUALITY PSH was discovered in a utility trench on March 29, 1995 that was dug for the repair of a sewer line located adjacent to the site. The release was reported to the NCDENR (predecessor of the NCDEQ) on the same date. On March 31, 1995 Spatco installed three monitoring wells (MW-1 through MW- 3) to evaluate fluid levels and to provide access for PSH recovery adjacent to the UST field. Soil samples collected during the well installations were analyzed for Total Petroleum Hydrocarbons (TPH) by EPA Methods 3550 and 5030. Analytical results for EPA Method 5030 detected concentrations of gasoline range organic (GRO) petroleum hydrocarbons with concentrations ranging from 248 to 12,946 parts per million. Diesel Range organics (DRO) were not detected in any sample. A summary of the historical soil TPH analytical results is located in Appendix D. Monitoring well soil sample locations are located on Figure 2. In an attempt to delineate the hydrocarbon plume, Spatco installed five additional monitoring wells (MW-4D through MW-8) on May 23-24, 1995 that included the collection of soil samples. The monitoring, abatement activities, and associated soil sampling for DRO and GRO performed by Spatco were documented in a report entitled "Free Product Recovery and Comprehensive Site Assessment Progress Report" dated July 14, 1995. A summary of soil analytical results is located in Appendix E and the well locations are shown on Figure 2. 6 Following the work performed by Spatco, a Comprehensive Site Assessment (CSA) was initiated by EMS that included the installation of thirteen additional monitoring wells MW-9 through MW-21D. At ten of these well locations, MW-9, MW-10, and MW-14 to MW-21D, soil samples were collected for TPH DRO and GRO. In support of the CSA, additional soil assessment activities were performed between November 10 to 13, 1995 that included a series of 17 geoprobes advanced at the T-Mart site and along the W. Barrington and N. McKay Street right-of-ways. A map showing the geoprobe locations is shown in Appendix E. A summary of soil analytical results for the monitoring well and geoprobe sample locations is located in Appendix E. Review of the historical soil analytical results for the geoprobe sample locations and monitoring wells reveals that none of the samples exhibited concentrations of GRO or DRO to be present above the NCDEQ Soil Action Limits in the upper two feet of soil. Of the 17-geoprobe soil samples and ten monitoring well soil samples collected, only three locations revealed a detectable concentration of any petroleum hydrocarbons. Sample GP-7 had a detectable concentration of 5.5 mg/Kg of GRO, MW-15 had 26.0 mg/Kg GRO, and MW-16 had 10.0 mg/Kg GRO reported. No DRO was reported to be present in any sample location. Soil quality sampling was last performed during the First Semiannual Period of 2019 around the dispenser islands. The purpose of the investigation was to determine if the dispensers were the source area of historical PSH on site and if soil quality in that area was acting as a secondary source for dissolved phase petroleum hydrocarbons. Eight soil borings, identified as SB-1 through SB-8, were advanced at the locations shown in Appendix D on April 23, 2019. One soil sample was collected at or near the boring termination depth for TPH analyses of DRO and GRO. In addition, one soil sample with the highest VOCs screening level, SB-8, was additionally submitted for Risk Based Corrective Action (RBCA) analyses to include EPA Method 8260, EPA Method 8270, and Massachusetts Department of Environmental Protection (MADEP) Extractable Petroleum Hydrocarbons (EPH) and Volatile Petroleum Hydrocarbons (VPH). Laboratory analytical results are summarized in Appendix D. The analytical results from the dispenser island sample event resulted in a detectable concentrations of GRO above the NCDEQ Soil Action Level of 50 mg/Kg in samples SB-4 (130 mg/Kg), SB-5 (7,800 mg/Kg), SB-6 (2,400 mg/Kg), SB-7 (95 mg/Kg), and SB-8 (2,500 mg/Kg). Laboratory analytical results for DRO in samples SB-3 (110 mg/Kg), SB-5 (690 mg/Kg), SB-6 (170 mg/Kg), and SB-8 (510 mg/Kg) were reported above the NCDEQ Soil Action Level of 100 mg/Kg. All other soil samples were reported at concentrations less than the GRO and DRO action level. Results of the RBCA laboratory soil analysis for soil sample revealed the presence of multiple EPA Method 8260 and EPA Method 8270 target compounds. Of the detected compounds, none were reported above its corresponding Soil to Groundwater Maximum Soil Contaminant Concentration (MSCC). No reported concentration of any compound was above the applicable Residential MSCC. Analysis by MADEP EPH and VPH of soil sample SB-1 revealed the C9-C22 aromatic range as the only petroleum fraction detected above the Residential MSCC. 7 Excavation of the secondary source soils in the vicinity of MW-27, MW-28, RW-5 and RW-6 occurred between November 1 through 3, 2021 with site reconstruction occurring from November 3 through 8, 2021. Impacted soil was observed to be present by visual, olfactory, PID field screening methods and was confirmed by a contracted mobile onsite laboratory during the excavation process. A total of 542.32 tons of impacted soils (22 loads) was excavated by Zebra and direct loaded into dump trucks for off-site disposal at Carlisle Farms, Inc., a NC certified land farm dedicated land farm located in Autryville, North Carolina. Figures of excavation areas and summary tables of disposal soil sampling results are included in Appendix D. 5.0 CONCLUSIONS AND RECOMMENDATIONS Based on the results of the activities performed during the reporting period, the following conclusions and recommendations are made for future site activity: • Secondary source soil excavation within the GCL groundwater plume during the second annual period of 2021 appears to have partially successful since groundwater concentrations in that area are continuing to decline. • PSH was not measured this period in any sampled monitoring well. • An analyses by EPA Method 6200B did not reveal the detectable concentration of any compound above the respective GCL this period. This marks the first period where no detectable compound was reported above the GCL. • Dissolved phase total BTEX concentrations decreased in wells MW-15, MW-23, MW-26, MW-27R, and MW-28R this period. Dissolved phase MTBE concentrations decreased in wells MW-3 (RW-2), MW-15, MW-26, MW-27R, MW-28R, and RW-5 this period. • Continued reduced schedule semi-annual groundwater monitoring well sampling is recommended to be performed in the Second Semi-annual period of 2023 to further evaluate the effectiveness of the secondary source soil removal efforts. Monitoring well sampling would be performed in November of 2023 with reporting in December of 2023. • Additional MMPE events or alternate groundwater cleanup techniques, such as the injection of oxygen releasing compounds, may be recommended if groundwater concentrations rebound above the GCLs in any well.
