(ATC) has performed consulting services for Stephens Exxon, located at 20655 North Carolina Highway 88 West, Creston, Ashe County, North Carolina. The adjoining properties include residential with limited commercial use to the north and west, with agricultural use to the south and east to a tributary of the North Fork River. This work was performed based on the April 12, 2023 Task Authorization (TA-01) 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 was performed as part of the State Lead Contract # N70522-B between NCDEQ and ATC. As of May 2023, the site is used as a workshop by the current property owners (purchased May 18, 2021). According to previous reports, there appear to be two separate plumes at the site: a gasoline plume located on the northeastern section of the site in the vicinity of MW-5R and a kerosene plume located west of the on-site building near MW-11. Former petroleum USTs at the site released petroleum product to the subsurface which was reported during the removal of the USTs on October 7, 1996. Three 2,000-gallon gasoline USTs and one 560-gallon kerosene UST were identified in the NCDEQ Registered UST Database. During May 15 and 16, 2023, ATC sampled groundwater monitoring wells MW-2, MW-3, MW-5R, MW-7, MW-11, MW-12, MW-13, MW-14, MW-16, and MW-17, air sparge well AS-1, and water supply well WSW-8. All samples were analyzed for volatile organic compounds (VOCs) using Standard Method (SM) 6200B and samples from wells MW-11, MW-13, AS-1, and WSW-8 were also analyzed for semi-volatile organic compounds (SVOCs) using EPA Method 625. ATC also measured the depth to groundwater and measured the top of casing elevations for all monitoring wells accessible on May 15 and 16, 2023. Monitoring well MW-4 could not be sampled due to a bent casing, monitoring wells MW-1, MW-6, MW-8, MW-9, and MW-10 could not be located, and monitoring well MW-15 could not be accessed for sampling on May 16, 2023 due to vehicle parked over the well. The following site conditions are noted based on the recent and historical assessment activities and are listed in the Conceptual Site Model (Appendix A):  Six water supply wells or springs are located within 1,000 feet of the source areas including three wells within 500 feet of the source areas. The “most at risk wells” include the on-site water supply well WSW-8 located approximately 60 feet from the kerosene release source area and approximately 160 feet southwest of the gasoline release source area. The other water supply wells do not appear to be at risk due to the locations and distances from the source areas. Municipal water is not available to the area;  Tributaries to the North Fork New River and the North Fork New River are located within 500 feet of the source areas;  Recent monitoring well sampling results indicated exceedances of the 15A NCAC 02L Groundwater Quality Standards (2L Standards) in wells MW-5R, MW-11, and MW-17, and exceedances of the 15A NCAC 2B Surface Water Quality Standards (2B Standards) by more than 10 times in well MW-5R. None of the reported concentrations of constituents exceeded the Gross Contamination Levels (GCLs);  Based on the groundwater level data, groundwater flow is generally to the southeast;  Based on the recent and historical groundwater quality data, the extent of the two contaminant plumes appear to be defined and stable. VOC concentrations in MW-5R have generally decreased with time, and appear to be generally stable in wells MW-11 and MW- 17. Light non-aqueous phase liquid or LNAPL (kerosene) was previously observed in well Monitoring Report June 23, 2023 Stephens Exxon – NCDEQ Incident #16457 ATC Project #STL1645701 3 MW-11, but has not been detected since April 19, 2022, following the May 2022 Mobile Multi-Phase Extraction and Air Sparge (MMPE/AS) event. Based on the information provided in this report, ATC recommends the following:  Continue to sample selected monitoring wells (MW-4, MW-5R, MW-6, MW-11, MW-13, MW-14, MW-15) and water supply well WSW-8. Evaluate results for plume stability based on the previous Fate & Transport Model results;  Conduct additional MMPE/AS events in the area of the two plumes to reduce VOC concentrations in pursuit of closing the incident;  Consider installation of a replacement water supply well for WSW-8, either on the source property, the property to the east (owned by Joseph S. Stephens, Jr., a prior owner of the source property), or the property to the south (owned by Joyce Stephens (L/E), a prior owner of the source property); and  Attempt to locate wells that could not be located in May 2023 and remeasure the top of casings of the wells. 3.0 SITE DESCRIPTION 3.1 Site Characterization The NCDEQ retained ATC to provide environmental consulting services for Stephens Exxon, located at 20655 North Carolina Highway 88 West, Creston, Ashe County, North Carolina. Figure 1 depicts the site location on a topographic map. The site building serves as a personal workshop and storage for the property owner. Three water supply wells have been previously identified within 1,000 feet of the site, with the on-site well WSW-8 located approximately 60 feet from the former kerosene UST considered the only “at risk” well. Municipal water is not available to the site vicinity. Figure 2 indicates the location of water supply wells in the site vicinity, and Table 1 provides the water supply well information. 3.2 Site Background The site formerly operated as Joe Stephen’s Exxon which utilized a UST system consisting of three 2,000-gallon gasoline USTs and one 560-gallon kerosene UST. The gasoline USTs were located near the northeast corner of the existing building. The kerosene UST was located along the west side of the existing building. The gasoline USTs were installed on May 5, 1975 and removed on October 7, 1996. The kerosene UST was installed May 4, 1976 and removed on August 13, 1998. On may 18, 2021, Vincent Boccardy and Courtney D. Cutillo purchased the source property from Richard J. and Linda O. Gouger, who purchased the source property from Joyce Stephens (widow) on June 15, 2012. Tank closure activities included the removal of the USTs and post-removal sampling. Soil samples collected from the floor of the gasoline UST basin and near the former dispenser location indicated total petroleum hydrocarbon gasoline-range organics (TPH-GRO) impact above the North Carolina State Action Level. Monitoring well MW-1 was installed by Salem Environmental on October 23, 1996. Geonetics Corporation (Geonetics) completed a Comprehensive Site Assessment (CSA) on July 18, 1997. According to CSA, shallow monitoring wells MW-2 through MW-6 and two temporary wells (TW-2 and TW-3) were installed in March 1997 by Geonetics to further delineate the petroleum impact at the site. A deep aquifer monitoring well, MW-7 was installed on June 4, 1997. During subsequent groundwater monitoring events, petroleum impact was Monitoring Report June 23, 2023 Stephens Exxon – NCDEQ Incident #16457 ATC Project #STL1645701 4 identified in samples collected from monitoring wells MW-1, MW-5, and TW-2 above 2L Standards. The CSA also identified possible receptors within 1,500 feet of the site. In March 1998, Geonetics installed two additional shallow monitoring wells MW-8 and MW-9. On August 13, 1998, Geonetics completed the excavation and removal of the kerosene UST. Approximately 7.3 cubic yards of contaminated soil was removed from the excavation. Soil samples were collected from the bottom of the UST basin and below the dispenser location. A composite sample was also collected from the excavated contaminated soil. Soil analysis indicated contamination exceeding the Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs) in the samples collected from the UST basin and dispenser location. None of the detected concentrations exceed residential MSCCs. Volatile and Semi-Volatile TPH were detected in the excavated soil at concentrations of 265.8 parts per million (ppm) and 1,524 ppm, respectively. Geonetics concluded that groundwater contamination was due to releases from the gasoline and kerosene UST systems. In 1998, Geonetics also submitted a Corrective Action Plan (CAP) proposing remedial actions at the site. Geonetics proposed corrective action alternatives including soil excavation, a soil vapor extraction system (SVE), and natural attenuation. Between June 30, 2003 and July 3, 2004 approximately 832.83 tons of contaminated soil was removed from the areas of the gasoline USTs and the kerosene UST. Post-excavation sampling indicated that contaminated soil had been removed except for soils beneath the water table and underneath the site building. Remaining impact exceeded soil-to-groundwater MSCCs; however, concentrations did not exceed residential MSCCs. During the time period, monitoring wells MW-11 and MW-12 were installed to further delineate petroleum impact. In 2004, Geonetics conducted groundwater monitoring of the site monitoring wells which indicated petroleum impact above 2L Standards in monitoring wells MW-5 and MW-11. Post-excavation soil samples were analyzed for petroleum constituents by Standard Method 8021 and MADEP VPH Method. In February 2011, Terraine Environmental (Terraine) conducted groundwater monitoring at the site. Monitoring well MW-11 contained one foot of measurable LNAPL. Petroleum impact was identified in monitoring wells MW-2, MW-3, MW-4, MW-7, and MW-12. Results from the groundwater sampling event did not indicate impact above 2L Standards; however, monitoring well MW-5 which historically contained impact, was not sampled. In August 2011, Terraine completed an AFVR on monitoring well MW-11. A total of 175 gallons of petroleum impacted water was removed from the well. Upon completion of the AFVR event, 0.2 feet of LNAPL was remaining in well MW-11. A post-AFVR sampling event was conducted at the site which indicated a decrease in impact in monitoring wells MW-4 and MW-12. Following the groundwater monitoring event, a Universal Remediation, Inc., PRP® Well Boom was installed in monitoring well MW-11 to aid in biodegradation of petroleum constituents. Subsequent groundwater monitoring events were performed at the site in 2012 and 2013 by Crawford Environmental Services. According to the GMR, LNAPL continued to be observed in monitoring well MW-11. Monitoring wells MW-5 and MW-6 were reported as destroyed and were not sampled. Detectable levels of one or more petroleum constituents were observed in monitoring wells MW-3 and MW-12. ATC completed a groundwater monitoring event in October 2014, during which time monitoring well MW-5 was located. LNAPL was identified in monitoring well MW-11 at a thickness of 0.76 feet. Groundwater impact above 2L Standards was identified in monitoring well MW-5 for Monitoring Report June 23, 2023 Stephens Exxon – NCDEQ Incident #16457 ATC Project #STL1645701 5 multiple constituents. No additional impact above 2L Standards was identified in the monitoring well network. ATC sampled groundwater monitoring wells MW-2, MW-3, MW-4, and MW-12 on August 9, 2018. During this sampling event, free-phase petroleum was identified in MW-11 at a thickness of 1.18 feet. Monitoring wells MW-4 and MW-12 contained concentrations of isopropyl ether and sec-butylbenzene, respectively, at concentrations below the 2L Standards. Monitoring wells MW-2 and MW-3 did not contain detectable concentrations of petroleum constituents. On March 14, 2019, monitoring wells MW-5R and MW-13 were installed to delineate the petroleum plume at the site. Monitoring well MW-5R replaced former well MW-5. Wells MW-5R and MW-13 were installed using hollow-stem auger technology to 14 feet below ground surface (ft bgs) and 12 ft bgs, respectively. During the monitoring well installation, the driller raised the access port of monitoring well MW-11, which was previously beneath approximately eight inches of compacted gravel. Well MW-11 was also finished with a flush mounted square well pad. In August 2021, a Mobile Multi-Phase Extraction (MMPE) was conducted by Terracon Consultants, Inc (Terracon) at monitoring well MW-7 and removed approximately 8 gallons of liquid free product and 3.33 gallons of VOCs as vapor. In April 2022, recovery well RW-1 and air sparge well AS-1 were installed by Terracon and Environmental Drilling & Probing Services (EDPS) in the vicinity of the kerosene plume on the west side of the on-site building. Following installation, Terracon performed a 96-hour MMPE/AS event in May 2022, using well RW-1 as the extraction well while sparging in AS-1. Approximately 7.67 gallons of petroleum hydrocarbons were recovered as vapors, 6 gallons free product was recovered as liquid, and 2,670 gallons of petroleum impacted groundwater were removed during this event. A groundwater sampling event was performed post-MMPE/AS on May 10, 2022. Terracon sampled groundwater monitoring wells MW-11, MW-13, and MW-14. LNAPL was not detected, although a “petroleum odor” was noted from the MW-11 purge water. Terracon concluded concentrations of VOCs have generally decreased in monitoring wells MW-11, MW-12, and MW-14 since September 2021. On September 26, 2022 Terracon sampled monitoring wells MW-4, MW-5R, MW-11, MW-13, MW- 15, and MW-17. MW-5R and MW-11 contained constituents above 2L Standards. Terracon also conducted a fate and transport evaluation on both sources areas to determine the possibility for migration to receptors WSW-8, WSW-9, and the North Fork of the New River. The fate and transport model predicted that contaminant concentrations are not likely to exceed the 2L Standards when steady state conditions are achieved, but may be impacted at levels below the 2L standards. 3.3 Site and Regional Geology According to the Geologic Map of North Carolina, produced by the State of North Carolina in 1985, the site lies in an area of unconformity in the Blue Ridge Belt of North Carolina. The rock type at the site has been identified as biotite granitic gneiss. In most areas, the upper Blue Ridge subsurface consists of unconsolidated residual soil, variously known as residuum, saprolite, or partially weathered rock (PWR) that has developed from in-place weathering of the underlying metamorphic bedrock. The residual soils vary in consistency and depth based on local conditions. Bedrock can be found at depths ranging from the surface as outcrops down to greater than 100 feet in areas of easily weathered rock types. Areas near streams and rivers in the Blue Ridge may also contain alluvium deposited during flood events. Monitoring Report June 23, 2023 Stephens Exxon – NCDEQ Incident #16457 ATC Project #STL1645701 6 According to available soil boring logs and excavation records for the site, soils encountered consisted of 10 to 15 feet of silty sand to sandy silt (fill material) around the site building, 2 to 6 feet of sandy silt (alluvium), 0.5 feet to 2 feet of a reported cobble layer (reported as a 15-foot layer of cobbles and gravel from 15 to 30 ft-bgs at the deep well MW-7), and bedrock (amphibolite with quartz) at 30 ft-bgs. Monitoring well MW-7 was screened in the bedrock. Auger refusal was reported in MW-13 at 12 feet, which may have been the cobble layer rather than bedrock. Based on the soil conditions observed during the installation of groundwater monitoring wells MW-14, MW-15, MW-16 and MW-17, the “cobble” layer consists of a poorly sorted sandy silty gravel with cobbles. The soil immediately above the gravel layer consists of a silty sand, which appeared to contain more water than the “cobble” layer, and presumably more permeable that the underlying “cobble” layer. The soil beneath the “cobble” layer consists of silt, likely residual soil weathered from the underlying bedrock, and of lower permeability than the overlying “cobble” layer. 3.4 Site and Regional Hydrogeology The shallow aquifer occurrence varies in depth from ground surface at springs, creeks, and rivers to as deep as 50 feet or more beneath upland surfaces in some parts of the Blue Ridge. ATC encountered groundwater between 2.35 feet below the top of casings (ft-toc) in MW-17 to 12.00 ft-toc in MW-5R during the May 2023 monitoring event. Water in the alluvium or unconsolidated residual material, including saprolite and PWR, usually behaves as an unconfined aquifer, or water table, and will yield water with head elevation equivalent to the first elevation where water was encountered. Permeability varies with lithology and is typically relatively low in residual soils, with higher permeability in saprolite or PWR due to relict rock texture and variable susceptibility to weathering exhibited by different minerals in the rock. Groundwater flow in residual soils or alluvium is usually in rough concurrence with local topographic conditions and is toward local drainage features. The bedrock fractures or other planar features of the Blue Ridge Physiographic Province generally constitute the bedrock aquifer, with the surrounding rock material being effectively impermeable. Along with fractures, contacts between rock bodies probably constitute zones of significant groundwater occurrence in the bedrock. The surrounding material and overlying residuum tend to make the bedrock aquifer a semi-confined aquifer. That is, the overlying water and soil weight normally results in pressure that causes water in a borehole, which intersects a fracture or other feature, to rise above the elevation of the fracture or feature. Most modern water supply wells in the Blue Ridge consist of a casing set through the residual soils into the upper bedrock followed by an open borehole into the bedrock where water-bearing fractures were encountered during the drilling. Except for sampling of the site and nearby water supply wells, evaluation of bedrock water quality or hydrology was beyond the scope of the GMR. Based on recent and historical groundwater level measurements at the site, the groundwater flow is to the southeast toward the North Fork New River (classified as Class C, Trout Waters, Outstanding Resource Waters). The North Fork New River is located approximately 470 feet from the former UST basin. Locally, a spring located north of monitoring well MW-2 is piped approximately 500 feet underground to the east into surface water described as a “pool” by Geonetics in the Comprehensive Site Assessment Report dated July 18, 1997. On the west side of the site, two tributaries to the North Fork New River are located approximately 70 and 120 feet west and southwest of the kerosene release area. The tributaries converge approximately Monitoring Report June 23, 2023 Stephens Exxon – NCDEQ Incident #16457 ATC Project #STL1645701 7 150 feet southwest of the kerosene source area then piped below ground to the southeast toward the river. The location of this pipe at the river is not known. Older topographic maps indicated that this tributary flowed to the east from the approximate beginning of the piped section. There is also a septic drain field located southeast of the site building. The influence on groundwater flow from these features has not been established; however, recent groundwater level data do not suggest that the piped spring and tributaries are significantly impacting the local groundwater surface. Note that prior groundwater sampling data from monitoring wells MW-8 and MW-9 located downgradient of the site and screened within the gravel (and possibly cobble) layer, did not indicate groundwater impact exceeding 2L Standards. Excluding wells MW-8 and MW-9, it considered likely that the groundwater surface is at a depth shallower than the cobble layer, thus, it was thought that the cobble layer may be a preferential flow path of groundwater and dissolved contaminants. However, based on soil conditions observed during the installation of monitoring wells MW-14, MW-15, MW-16, and MW-17, it is not apparent that “cobble” layer is more permeable than the overlying silty sand. 4.0 GROUNDWATER CHARACTERIZATION 4.1 Water Supply Wells Three water supply wells or springs have been previously identified within 1,000 feet from the site. Figure 2 depicts the locations of the water supply wells relative to the site. Table 1 summarizes water supply well and spring information, with all identified as WSW-#. Spring WSW-6 and well WSW-7 are located approximately 600 and 890 feet south of the site, respectively, and crossgradient to groundwater flow from the site. Thus, WSW-6 and WSW-7 are not likely at risk from the UST releases at the site. Well WSW-8 is located approximately 60 feet south of monitoring well MW-11 (with historical LNAPL). Springs WSW-9 and WSW-10 are located within 500 feet upgradient of the source areas. The other water supply sources are located upgradient or sidegradient of the source areas or across North Fork New River and are not considered to be “at risk” wells or springs. 4.2 Groundwater Levels On May 15, 2023, ATC measured the depth to groundwater for monitoring wells that were found and accessible: MW-2, MW-3, MW-4, MW-5R, MW-7, MW-11, MW-12, MW-13, MW-14, MW- 15, MW-16, MW-17, RW-1, and AS-1. Monitoring wells MW-1, MW-6, MW-8, MW-9, and MW- 10 could not be located during the monitoring event, using a metal detector. Groundwater monitoring wells MW-8 and MW-9 are located in an agricultural field and have not been located and sampled since March 1998. Figure 3 depicts a site map with the locations of the monitoring wells and former UST systems. Monitoring well construction details and groundwater level data are included in Table 2. An oil/water interface probe was used to measure the depth to groundwater from the top of well casing (TOC). A groundwater contour map is presented in Figure 4 which depicts groundwater flow generally to the southeast towards the North Fork New River. On May 16, 2023, ATC measured the top of casing elevations of accessible and found wells, relative to one another. A site benchmark was not established. The top of casing of well MW-2 was established as the “benchmark” with a relative elevation of 100 feet. Field notes from the May 2023, groundwater monitoring event are presented in Appendix B. Monitoring Report June 23, 2023 Stephens Exxon – NCDEQ Incident #16457 ATC Project #STL1645701 8 4.3 Groundwater Quality On May 15 and 16, 2023, ATC collected groundwater samples from monitoring wells MW-2, MW- 3, MW-5R, MW-7, MW-11, MW-12, MW-13, MW-14, MW-16, MW-17, RW-1, and AS-1. A field blank was also collected during this groundwater monitoring event. During sampling activities, a three-volume well purge was conducted prior to groundwater sample collection to ensure a representative groundwater sample. Water quality parameters were collected from each well once the purging process was complete, and are summarized in Table 3. Monitoring well MW-4 was unable to be sampled due to a bent casing. Monitoring well MW-15 was accessible on May 15, 2023 but not sampled on that day, and on May 16, 2023, a vehicle was parked over the well that prevented the sampling of the well. On May 16, 2023, ATC collected a water sample from water supply well WSW-8 after purging the well for approximately 15 minutes. The water samples were collected in laboratory-supplied, preserved containers; entered into chain of custody control; placed on ice; and shipped to North Carolina accredited Pace Analytical Services, LLC in Huntersville, North Carolina. The groundwater samples were analyzed by SM 6200B for VOCs. Additionally, samples MW-13, MW-14, AS-1 and WSW-8 were analyzed by EPA Method 625 for SVOCs. The analytical report is included in Appendix C. Recent monitoring well analytical results are summarized in Table 4. Recent analytical results for water supply well WSW-8 are summarized in Table 5. Historical monitoring well analytical results are shown in Table 6. Historical water supply well analytical results are shown in Table 7. The groundwater analytical results were compared to the 2L Standards, 2B Standards, and GCLs. Groundwater analytical results indicated the following:  Water supply well WSW-8 contained several VOCs at concentrations less than the 2L Standards;  Monitoring wells MW-5R, MW-11, and MW-17 contained one or more VOCs at concentrations above the 2L Standards;  Monitoring wells MW-5R contained toluene and naphthalene at concentrations exceeding the 2B Standards by more than 10 times; and  None of the detected concentrations of constituents exceeded GCLs. Groundwater analytical results exceeding the 2L Standards and the 2B Standards by more than 10 times are depicted in Figure 5, along with estimated extent of the kerosene and gasoline contaminant plumes. As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of the laboratory reports was conducted. During the review, it was found that the samples were received from the laboratory in acceptable condition and properly preserved. The samples were analyzed within correct holding times and reported within the lab report, and the chain of custody was properly completed by all parties. The laboratory QC report shows that 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. A field blank was also collected during the groundwater monitoring event. No other compounds were detected in the field blank. Refer to the laboratory reports 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. Monitoring Report June 23, 2023 Stephens Exxon – NCDEQ Incident #16457 ATC Project #STL1645701 9 5.0 CONCLUSIONS AND RECOMMENDATIONS On behalf of the Trust Fund Branch of the UST Section, ATC has completed a Monitoring Report documenting the May 2023 groundwater monitoring event for Stephens Exxon, located at 20655 North Carolina Highway 88 West, Creston, Ashe County, North Carolina. During May 15 and 16, 2023, ATC sampled groundwater monitoring wells MW-2, MW-3, MW-5R, MW-7, MW-11, MW-12, MW-13, MW-14, MW-16, and MW-17, air sparge well AS-1, and water supply well WSW-8. All samples were analyzed for volatile organic compounds (VOCs) using Standard Method (SM) 6200B and samples from wells MW-11, MW-13, AS-1, and WSW-8 were also analyzed for semi-volatile organic compounds (SVOCs) using EPA Method 625. ATC also measured the depth to groundwater and measured the top of casing elevations for all monitoring wells accessible on May 15 and 16, 2023. Monitoring well MW-4 could not be sampled due to a bent casing, monitoring wells MW-1, MW-6, MW-8, MW-9, and MW-10 could not be located, and monitoring well MW-15 could not be accessed for sampling on May 16, 2023 due to vehicle parked over the well. The following site conditions are noted based on the recent and historical assessment activities and are listed in the Conceptual Site Model (Appendix A):  Six water supply wells or springs are located within 1,000 feet of the source areas including three wells within 500 feet of the source areas. The “most at risk wells” include the on-site water supply well WSW-8 located approximately 60 feet from the kerosene release source area and approximately 160 feet southwest of the gasoline release source area. The other water supply wells do not appear to be at risk due to the locations and distances from the source areas. Municipal water is not available to the area;  Tributaries to the North Fork New River and the North Fork New River are located within 500 feet of the source areas;  Recent monitoring well sampling results indicated exceedances of the 2L Standards in wells MW-5R, MW-11, and MW-17, and exceedances of the 2B Standards by more than 10 times in well MW-5R. None of the reported concentrations of constituents exceeded the GCLs;  Based on the groundwater level data, groundwater flow is generally to the southeast;  Based on the recent and historical groundwater quality data, the extent of the two contaminant plumes appear to be defined and stable. VOC concentrations in MW-5R have generally decreased with time, and appear to be generally stable in wells MW-11 and MW- 17. LNAPL (kerosene) was previously observed in well MW-11, but has not been detected since April 19, 2022, following the May 2022 MMPE/AS event. Based on the information provided in this report, ATC recommends the following:  Continue to sample selected monitoring wells (MW-4, MW-5R, MW-6, MW-11, MW-13, MW-14, MW-15) and water supply well WSW-8. Evaluate results for plume stability based on the previous Fate & Transport Model results;  Conduct additional MMPE/AS events in the area of the two plumes to reduce VOC concentrations in pursuit of closing the incident;  Consider installation of a replacement water supply well for WSW-8, either on the source property, the property to the east (owned by Joseph S. Stephens, Jr., a prior owner of the source property), or the property to the south (owned by Joyce Stephens (L/E), a prior owner of the source property); and  Attempt to locate wells that could not be located in May 2023 and remeasure the top of casings of the wells.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPAMethod 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.
