This October2078 Groundwater Monitoring Report has been prepared for the North Carolina Department of Transportation (NCDOT) Geotechnical Engineering Unit to document the groundwater conditions in accordance with Underground Injection Control (UIC) Program Permit No. W10300282. It describes the activities and results of the groundwater sampling event that took place in October 2018. 1.1 SITE BACKGROUND Prior to NCDOT acquisition, the Site was operated as a convenience store and gasoline station from 1968 to 1994 (S&ME, 2001). The underground storage tank (UST) system at the former station consisted of four USTs and one pump island with associated product dispensers. The NCDOT purchased the property from Mr. Walter Preslar in 1994, and removed the USTs from the Site during tank closure activities in January 1995. The NCDOT demolished the remaining building on site shortly after the tank closure activities to accommodate widening INC Highway 24/27. After road construction was finished, the grass median between the eastbound and westbound lanes of NC Highway 24/27 contained the former UST basin. In August 1995, S&ME, Inc. (S&ME) completed a receptor survey that identified 13 water supply wells located within 1,500 feet of the site. These wells resulted in the site receiving a high -risk groundwater classification. Subsequent to the classification, the NCDOT successfully negotiated closure of all but two of the wells. Thirteen monitoring wells (Table 1 and Figure 2) have been installed at the Site since the USTs were removed in 1995. A Comprehensive Site Assessment (CSA) completed in August 2001 (S&ME, 2001) identified petroleum contamination in groundwater originating from a probable source area near the former gasoline USTs. A CSA addendum in January 2002 completed the groundwater plume delineation (S&ME, 2002a). S&ME completed the soil contamination delineation and prepared a second addendum in November 2002 (S&ME, 2002b). 11 October 2018 Groundwater Monitoring Report Former Preslar's Exxon Midland, Cabarrus County, NC DAA Project No. 17117301-010701 NCDOT WBS # 34348.3.5 November 9, 2018 The CSA reported detections of petroleum constituents above 15A NCAC 2L 0.0202 Groundwater Standards (NC 2L Standards) in four of the 13 monitoring wells (MW-1, MW-3, MW-4, and MW-5). Benzene, ethylbenzene, toluene, total xylenes, methyl-tert-butylether (MTBE), isopropylether (IPE), naphthalene, C5-C8 aliphatics, C9-C18 aliphatics, and C9-C22 aromatics exceeded the INC 2L Standards in one or more of the monitoring wells. The analyses also detected the halogenated compounds chloroform, bromodichloromethane, and dibromochloromethane above NC 2L Standards in groundwater samples collected from monitoring wells MW-3, MW-6, MW-7 and MW-8 located south of INC Highway 24/27. These trihalomethanes in the groundwater were presumed to be the result of well construction activities that used treated municipal water in the well construction process. The CSA concluded that the presence of these halogenated compounds in the groundwater was not likely related to the petroleum -release incident at the Site. In March 2005, DAA prepared a Corrective Action Plan (CAP) for the North Carolina Department of Environment and Natural Resources, now the North Carolina Department of Environmental Quality (NCDEQ) UST Section, Mooresville Regional Office (MRO), that recommended in situ chemical oxidation (ISCO) using an iron- and steam -activated sodium persulfate injection as the remediation alternative (SIES, 2005). From 2005 to 2012, the NCDOT made attempts to reduce the risk classification of the site by abandoning nearby water supply wells and irrigation wells within 1000 feet of the source area. However, a replacement well for one of the closer irrigation wells did not yield sufficient water for the owner's use, so the original irrigation well could not be abandoned and reclassification was not an option. As a result of groundwater sampling subsequent to the CAP, DAA determined that the groundwater was in an anaerobic state, not aerobic and ISCO would not be a suitable remedy. Instead, a CAP Addendum (SIES, 2012) compared a sulfate -enhanced bioremediation using EAS° (for anaerobic conditions) with vacuum extraction/air sparging. The CAP Addendum recommended the sulfate -enhanced bioremediation as the preferred groundwater remedy. The UST Section MRO issued a Notice of Regulatory Requirements (NORR) to NCDOT dated August 14, 2012, requesting results of pilot testing of the EAS® technology before completing their review of the addendum. DAA implemented the pilot test 2 October 2018 Groundwater Monitoring Report Former Preslar's Exxon Midland, Cabarrus County, NC DAA Project No. 17117301-010701 NCDOT WBS # 34348.3.5 November 9, 2018 in June 2012, and submitted the EAS Technology Evaluation Report (SIES, 2013) on January 23, 2013. The UST Section MRO provided approval of the CAP Addendum in a NORR dated August 14, 2013. On March 31, 2015, the NCDOT received Injection Permit W10300282 from the NCDEQ Division of Water Resources (DWR) UIC Program for the installation of 21 injection wells and approval to inject EAS® substrate into the groundwater at the Site. In April 2015, 19 permanent injection wells were installed at the site. Two previously installed pilot study wells were used as injection wells, which brought the total number of injection wells to 21. The initial full-scale injection event was performed on May 18 to 20, 2015, in which 1,113 gallons of EAS® were injected (SIES, 2015). Following the injection, DAA conducted post -injection groundwater monitoring events at 1-, 3-, and 6-month intervals. The analytical results indicated that petroleum compounds were decreasing in the 1- and 3-month intervals, but had increased to pre -injection concentrations at the 6-month interval. Based on these results, DAA and NCDOT requested approval to conduct a second injection event. A second injection event was approved and was conducted in April 2016 (SIES, 2016). From April 11 to 14, 2016, DAA gravity -fed EAS® into each injection point directly from the 55-gallon drum in which it was shipped. As with the first injection event, 1,113 gallons of EAS° were injected into the 21 injection wells. A 6-month post -injection groundwater monitoring event indicated a reduction in contamination. On June 1, 2016, the NCDEQ issued "North Carolina Petroleum UST Release Corrective Action Phase Project Management: A Calibrated Risk -based Corrective Action Decision & Implementation Guide." This document states that when groundwater contamination is below the Gross Contaminant Levels (GCLs) and is shown to be stable, active remediation may be halted and either MINA continues or the site is closed. Based on the April 2016 data, the NCDEQ directive, and personal conversations with the NCDEQ incident manager for this site, the NCDOT was directed that monitoring -only was required for the Site. Following the receipt of the October 2017 Groundwater Monitoring Report, the NCDEQ, by a Notice of Regulatory Requirements dated January 9, 2018, approved a request to change the frequency of sampling from semi-annual to annual. This October 2018 report is the first report since that change. 9 October 2018 Groundwater Monitoring Report Former Preslar's Exxon Midland, Cabarrus County, NC 2.0 GROUNDWATER MONITORING DAA Project No. 17117301-010701 NCDOT WBS # 34348.3.5 November 9, 2018 The approved injection permit monitoring plan requires groundwater level measurement and sampling at the 13 monitoring wells. The permit also requires that groundwater samples be collected from two water supply wells (WSW-10 and WSW-11). This scope of work was done on October 8-9, 2018. 2.1 GROUNDWATER ELEVATIONS Prior to collecting groundwater level measurements, DAA personnel opened each monitoring well to allow the water level to equilibrate. Field personnel used an electronic water level indicator with a decontaminated down -hole probe to measure water levels in each monitoring well. The depth -to -water measurements were converted to elevations by subtracting the depth -to -water measurement from the top -of -casing elevation that was surveyed by the NCDOT. Table 1 presents the October 2018 water level data and previous water level measurements. The data show that seasonal fluctuations of several feet can occur. The groundwater elevation data for wells screened in the shallow aquifer were used to develop a shallow potentiometric surface map for October 2018 (Figure 3). The groundwater contour map shows that shallow groundwater generally flows to the southeast, which is similar to previous findings. However, because bedrock is present at a depth of about 4 to 6 ft bgs, groundwater flow may be fracture -controlled and local variations to the apparent flow direction may be present. 2.2 GROUNDWATER SAMPLING DAA collected groundwater samples using low -flow purging methods after measuring the water level in each monitoring well. While purging, personnel recorded pH, temperature, specific conductance, dissolved oxygen (DO), and oxidation-reduction potential (ORP) (Table 2) until each parameter stabilized or until the wells were nearly purged dry. The water sample from well WSW-10 was collected by lowering a submersible pump into the well and from well WSW-11 by using the existing well pump and pressure tank. The pumps were run for approximately 15 minutes to purge the system and obtain a representative sample. 4 October 2018 Groundwater Monitoring Report Former Preslar's Exxon Midland, Cabarrus County, NC DAA Project No. 17117301-010701 NCDOT WBS # 34348.3.5 November 9, 2018 Groundwater samples from the monitoring wells were collected directly into laboratory -supplied containers via peristaltic pump. Groundwater samples from the water supply wells were collected from the nearest available spigot to the pressure tank or from the pump tubing directly into the bottles. The samples were stored on ice and transported under chain -of -custody control to Pace Analytical Services (Pace Lab) in Huntersville, North Carolina for analysis of sulfate by EPA Method 300.0 and volatile organic compounds (VOCs) by SM 6200B. 2.3 GROUNDWATER MONITORING RESULTS Table 3 summarizes the results of the target compounds detected since the initial injection was conducted and Table 4 summarizes the historical results of all detections. The applicable NC 2L Standards are included for comparison. The laboratory analytical report for the October 2018 monitoring event is provided in Appendix A. Constituent detected above their respective NC 2L Standards were: • Benzene (MW-4, MW-13), • Ethylbenzene (MW-4), • n-propylbenzene (MW-4, MW-13), and • naphthalene MW-4, (MW-13) Constituents detected at less than their respective NC 2L Standard were: • ethylbenzene (MW-13), • IPE (MW-4, MW-12, MW-13), • toluene (MW-4, MW-13), • total xylenes (MW-4, MW-13), • sec -butyl benzene (MW-4, MW-13), • isopropyl benzene (MW-1, MW-4, MW-13), • 1,2,4-trimethyl benzene (MW-4, MW-13), • 1,3,5-trimethyl benzene (MW-4, MW-13), and • 1,3,5-trimethyl benzene (MW-1, MW-4, MW-13) The remaining wells contained no detectable concentrations of VOCs for constituents analyzed. Figure 4 presents an interpretation of the lateral extent of benzene impacts identified in the shallow groundwater. As shown on Table 3, the constituents detected above their respective 2L Standard are within the post 2015 full-scale injection historical range. 5 October 2018 Groundwater Monitoring Report Former Preslar's Exxon Midland, Cabarrus County, NC DAA Project No. 17117301-010701 NCDOT WBS # 34348.3.5 November 9, 2018 Benzene in MW-1 has shown no Mann -Kendall trend in concentrations since implementation of the full- scale injection program (Appendix B). However, the concentrations of benzene in samples from that well have been below the method detection level for the last four sampling events. The benzene Mann - Kendall analysis also shows a stable trend in the concentrations in well MW-13, and an overall decreasing trend in concentrations from well MW-4. The naphthalene Mann -Kendall analyses for MW-4 and MW- 13 shows a probable increasing trend and decreasing trend, respectively. The relationships are illustrated on the charts in Appendix B. The laboratory conducted sulfate analysis on all the monitoring well samples collected. The results indicate detections of sulfate in all the monitoring well samples ranging from not detected to 96 milligrams per liter (mg/Q. None of these results is above the NC 2L Standard of 250 mg/L for sulfate. For samples from wells MW-1, MW-4, and MW-13 (within the contamination zone), the sulfate concentrations are decreasing. The concentrations in the remainder of the well samples appear stable at or near the naturally -occurring concentrations. The depletion of sulfate in the contamination area indicates microbial action and ongoing natural attenuation. In addition to the monitoring wells, two non -potable water supply wells (WSW-10 and WSW-11) were sampled and analyzed for VOCs and sulfate. No VOCs were detected in either sample. Sulfate was detected at concentrations below the 2L Standard in WSW-10 (36 mg/L) and WSW-11 (39 mg/Q. The concentration in well WSW-11 was of concern to the NCDEQ because the initial post -injection samples indicated an increase in sulfate in that well sample. However, the sulfate concentration has decreased since August 2015 and is approaching the baseline concentration. Z October 2018 Groundwater Monitoring Report Former Preslar's Exxon Midland, Cabarrus County, NC 3.0 CONCLUSIONS DAA Project No. 17117301-010701 NCDOT WBS # 34348.3.5 November 9, 2018 The petroleum source area for the Site is located in the median of INC Highway 24/27. The contaminant plume encompasses the source area as well as a small area along the eastbound right-of-way. Based on the available data, shallow groundwater appears to flow to the southeast. The primary constituents above the NC 2L Standards are limited to benzene, ethylbenzene, n-propylbenzene, and naphthalene. However, these constituents continue to show a general downward trend in the injection performance monitoring wells. Although other VOCs were detected, their concentrations were below the NC 2L Standards. In accordance with the 2016 NCDEQ Decision & Implementation Guide, the site concentrations were compared to the Gross Contaminant Levels (GCLs). The concentrations of concern, benzene, ethylbenzene, naphthalene, and n-propylbenzene, are below the GCLs and appear stable or decreasing in the areas of highest concentrations (Appendix B). However, the site remains a high risk. In July 2017, the NCDOT submitted a Risk Reclassification Request for the Site to the NCDEQ. The report supported the request using the site history and analytical results to determine trends in plume size (decreasing), contaminant mass (decreasing), center of plume stability (stable), location of the plume within the NCDOT right-of-way, and no contaminant concentrations detected in the non -potable wells. The NCDEQ reviewed the request, but wanted confirmation that the sulfate concentrations in well WSW- 11 were not increasing. Based on the results of the October sampling event, sulfate is well below the INC 2L Standard and no other parameter noted above has changed. As a result, the NCDOT requests the NCDEQ consider reclassifying the site to intermediate or low risk. Should reclassification not be granted, the NCDOT requests that the number of wells sampled annually be reduced to those exhibiting on -going detectable concentrations and immediate downgradient wells. These wells include MW-1, MW-4, and MW-13 within the historically contaminated area and wells MW-3 and MW-12 as sentinel wells.
