Nine underground storage tanks (USTs) were previously operated at the site. Two 2,000-gallon and one 500-gallon USTs were removed in May 2016 and a petroleum release was discovered during tank closure activities. Two 4,000-gallon and one 500-gallon USTs were removed in 2019, and at least one additional release was confirmed. The purpose of this report is to document the latest monitoring well installation and groundwater sampling event. On February 1, 2023, CATLIN Engineers and Scientists (CATLIN) personnel advanced three borings for construction of Type II monitoring wells (MW-5, MW-6, and MW-7) to 20 feet below land surface (BLS). The depth to water (DTW) at monitoring wells (MW-1, MW-3, and MW-4) was gauged prior to drilling activities at an average of approximately 15 feet deep. Monitoring well MW-2 was dry. When CATLIN returned to gauge the new wells on February 2, 2023, light non-aqueous phase liquid (LNAPL; aka free product) was measured in all three wells (ranging from 0.61 to 0.66 feet thick). From April 10 through 14, 2023, CATLIN coordinated a mobile multi-phase extraction (MMPE) event conducted by Eastern Environmental Management (EEM). A total of 14,382 gallons of impacted groundwater and LNAPL were recovered, as well as a calculated 6,163.82 pounds (equivalent to 986.21 gallons) of petroleum vapors. CATLIN returned to the site on May 11, 2023 for sampling activities. Groundwater was measured at approximately 15 feet deep across the site. LNAPL was not measured in any of the monitoring wells. Groundwater samples from six monitoring wells (MW-1, MW-3, MW-4, MW-5, MW-6, and MW-7) were collected. The samples were submitted for laboratory analysis of volatile organic compounds (VOCs) per Standard Method (SM) 6200B plus ethylene dibromide (EDB), methyl tert-butyl ether (MTBE), and diisopropyl ether (DIPE). Laboratory results did not indicate any dissolved petroleum constituents above their respective laboratory reporting limits in the samples from MW-3 and MW-4. Several VOCs were detected in the MW-1, MW-5, MW-6, and MW-7 samples at concentrations greater than those established in Title 15A of the North Carolina Administrative Code, Subchapter 2L, Section .0202 Groundwater Quality Standards (2L GWQS), but below the Gross Contaminant Levels (GCL). The contaminant concentrations reported from MW-1 during this period are generally higher than those in the previous sampling event in November 2022. CATLIN recommends attempting to obtain access for sampling WSW-1, WSW-4 and WSW-7 and conducting another mobile multi-phase extraction (MMPE) event followed by a monitoring/sampling event. NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 3 June 2023 3.0 SCOPE OF SERVICES The scope of services for this report was performed in general accordance with CATLIN proposal number 220284.3P, dated January 24, 2023. Services were authorized by the North Carolina Department of Environmental Quality’s (NCDEQ’s) Task Authorization (TA) #03, accepted on January 25, 2023, and Contract Number N122019D. The approved scope of services for this Task Authorization included to: •Update the site-specific Health and Safety Plan (HASP) for drilling activities; •Install three Type II monitoring wells (MW-5, MW-6, and MW-7) to 20 feet BLS; •Survey the top of casing (TOC) elevations of four monitoring wells (threenewly installed wells and one preexisting well); •Gauge three monitoring wells (MW-1, MW-3, and MW-4) once prior to drilling and once prior to sampling; •Gauge and collect groundwater samples from four monitoring wells (MW-2,MW-5, MW-6, and MW-7); •Analyze five water samples (four monitoring well samples and one trip blank)according to SM 6200B (including EDB, MTBE, and DIPE); and, •Prepare and submit a monitoring report summarizing the findings. Due to the presence of LNAPL in the newly installed monitoring wells, a Change Order was proposed and accepted on February 3, 2023. The approved scope of services for this Change Order included to: •Coordinate and oversee a MMPE event utilizing monitoring wells MW-5, MW-6, and MW-7 as extraction points; and •Conduct a groundwater sampling event approximately 30 days after theMMPE event. The scopes of services were conducted in accordance with the approved TA and associated Change Order. 4.0 SITE HISTORY AND CHARACTERIZATION The Hall’s Store site is located at 9830 High House Road, Salemburg, Sampson County, North Carolina (Figures 1 and 2). Summarized available historical sampling and gauging data from previous consultants are provided in Appendix A. Recent site photographs are presented in Appendix B. 4.1 UST OWNER AND OPERATOR INFORMATION Hall’s Store, LLC (Hall’s Store) owned the six registered USTs historically operated on-site. The former grocery store and petroleum service station NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 4 June 2023 operated the tanks for retail petroleum sales. Three additional unregistered USTs were discovered during a geophysical survey in 2018. There is no available owner or operator information for the three additional tanks. The site was accepted into the North Carolina UST Section Trust Fund Branch State Lead Program in 2018 (NCDEQ, 2018). Available information regarding UST owners/operators is presented on Table 1. 4.2 UST INFORMATION Four gasoline and two kerosene USTs were previously operated on-site by Hall’s Store. Two 3,000-gallon gasoline USTs and one 500-gallon kerosene UST were installed in May 1976 and closed by removal in December 1993. Two 2,000-gallon gasoline USTs were installed in September 1986 and were removed in May 2016. A 500-gallon kerosene UST (installation date unknown) was also removed in 2016. Soil staining and a strong petroleum odor was noted in the soil beneath the removed 500-gallon kerosene UST (S&ME, 2019A). During a 2018 geophysical survey performed by S&ME, Inc. (S&ME), two 4,000-gallon unregistered USTs were discovered approximately seven feet north of monitoring well MW-2 and were closed by removal in October 2019. The presence of a previously discovered unregistered 500-gallon UST was also confirmed and removed in September 2019 (S&ME, 2019B). Available UST system information is presented in Table 1 and the approximate known former UST basin locations are illustrated on Figure 3. 4.3 CONTAMINANT SOURCE INVENTORY An on-site release was discovered in May 2016 during UST removal activities. Soil sample analytical results reported total petroleum hydrocarbons (TPH) at concentrations up to 8.1 milligrams per kilogram (mg/kg). Petroleum-impacted groundwater was confirmed in June 2016 during sampling of monitoring well MW-1, installed near the UST basin. Several contaminants were identified above their 2L GWQS. It was concluded that groundwater impacts were likely the result of one or more releases from the gasoline UST system (ECE, 2016). During the installation of monitoring well MW-2 in 2018, a strong petroleum odor was noted. Soil sampling revealed multiple contaminants exceeding their Soil-to-Groundwater (STGW) maximum soil contaminant concentrations (MSCC). This led to the discovery of two additional unregistered USTs that had contributed to the release (S&ME, 2019A). NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 5 June 2023 4.4 SITE CHARACTERISTICS The property is owned by Kyle Hall and the former store structure is now vacant. The parcel is comprised of the store building and agricultural land. 4.5 OWNERS AND OCCUPANTS OF ADJOINING/NEARBY PROPERTIES AND LAND USE Properties in the site vicinity are mostly residences and agricultural land. A residence, with an active potable water supply well, adjoins the property to the east. Agricultural fields are located to the west (across Dunn Road) and south (across High House Road). A parcel with a residence and active potable water supply well is also located to the south. A former gasoline/country store, presently operating as a Church, is located across the Dunn-High House intersection to the southwest. Wooded land adjoins the site property to the north. 4.6 RECEPTOR INFORMATION Conducting a receptor survey was outside the scope of this monitoring event. A review of historical files available on the NCDEQ Waste Management Online Database (aka Laserfiche) indicates that the last receptor survey for the Hall’s Store site was conducted in 2018 by S&ME. According to previous reports, municipal water is available to the site vicinity, but multiple residences continue to use their private water supply wells for drinking water and irrigation. No water supply wells were identified within 250 feet of the site. Twelve water supply wells have been identified within 1,000 feet of the source area. Ten potable water supply wells are located within 1,000 feet of the site and of those, four (WSW-4, WSW-7, WSW-8, and WSW-9) are within 500 feet of the release and two (WSW-8 and WSW-11) are inactive. Two of the wells (WSW-8A and WSW-10) are used only for irrigation, and as of 2018 one (WSW-8A) was inactive. A drainage ditch is located approximately 200 feet north-northeast of the site. No other surface water bodies were noted. Potential receptors are illustrated on Figure 2 and receptor information from S&ME (2019) is shown in Table 2. 4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES As discussed above, the release was discovered in 2016 during UST closure activities. During UST removal, approximately 130 tons of petroleum impacted soil were removed from the site. Composite soil samples contained TPH gasoline range organics (GRO) and diesel range organics (DRO) concentrations up to 7.8 mg/kg and 8.1 mg/kg, respectively. Multiple NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 6 June 2023 petroleum constituents were also detected in a groundwater sample at concentrations above their respective 2L GWQS (ECE, 2016). A Limited Site Assessment (LSA) report was prepared in 2016, and in 2018 three additional monitoring wells (MW-2, MW-3, and MW-4) were installed at the site. Strong petroleum odors were noted during the installation of MW-2, and a soil sample was collected. Analytical results revealed multiple targeted analytes above their STGW MSCC. During subsequent sampling activities, LNAPL (1.44 feet) was measured in MW-2. Groundwater samples were collected from the remaining wells (MW-1, MW-2, and MW-4). Analytical results revealed naphthalene and 1,2,4-trimethylbenzene at concentrations above their 2L GWQS in the MW-1 sample. No VOCs were detected in the samples from MW-3 and MW-4 (S&ME, 2019A). Due to the elevated contamination in monitoring well MW-2, a geophysical survey was conducted in December 2018. Two additional unregistered USTs were discovered, and the location of a third previously identified tank was confirmed. These tanks were removed from the site in late 2019. A total of 486.70 tons of petroleum impacted soil was excavated and removed during tank closure activities. Risk-based soil samples were collected from the UST excavation but were reportedly lost by the courier and never analyzed. Analytical results for TPH revealed GRO and DRO concentrations up to 12,000 mg/kg and 870 mg/kg, respectively. Reports available on Laserfiche indicate that all known USTs have now been removed from the site (S&ME, 2019B). CATLIN conducted a groundwater monitoring event in July 2021. Three monitoring wells (MW-1, MW-3, and MW-4) were sampled. LNAPL was measured in MW-2 at 0.88 feet thick; therefore, this well was not sampled. No analyzed compound concentrations were detected above their laboratory reporting limits in the MW-3 and MW-4 samples. Laboratory analysis indicated several targeted analytes in the MW-1 sample; however, they were all below their 2L GWQS (CATLIN, 2021). In October 2022, CATLIN coordinated an aggressive fluid vapor recovery (AFVR) event utilizing monitoring wells MW-1 and MW-2 as extraction points. The eight-hour event removed a total of 980 gallons of impacted groundwater and 45.26 pounds of petroleum vapor (equivalent to 7.24 gallons of petroleum) were removed from the subsurface (CATLIN, 2022). CATLIN personnel returned to the site in November 2022 and sampled monitoring well MW-1. No LNAPL was observed in the well. Monitoring wells MW-2 and MW-3 were dry at the time of field activities. Laboratory analysis revealed that several targeted analytes were detected at low or estimated (“J”-value) concentrations, but all were below their respective 2L GWQS. CATLIN attempted to gain access to sample water supply wells WSW-4 and WSW-7 but received no response (CATLIN, 2022). NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 7 June 2023 Summarized historical data prepared by S&ME are presented in Appendix A. Site photographs are included in Appendix B. 5.0 REGIONAL AND SITE GEOLOGY AND HYDROGEOLOGY 5.1 SOIL AND BEDROCK As defined in the Geologic Map of North Carolina, published by the North Carolina Department of Natural Resources and Community Development (1985), the site lies within the Coastal Plain physiographic province. The North Carolina Coastal Plain is approximately 90 to 150 miles wide from the Atlantic Ocean westward to its boundary with the Piedmont province. Two natural subdivisions of the Coastal Plain were described by Stuckey (1965): the Tidewater region and the Inner Coastal Plain. The project area is located within the Inner Coastal Plain, which is an area of erosional topography (Horton and Zullo, 1991). The Coastal Plain comprises a wedge-shaped sequence of stratified marine and non-marine sedimentary rocks deposited on crystalline basement. The sedimentary sequences range in age from Recent to lower Cretaceous (Narkunas, 1980). The site is underlain by the Black Creek formation. According to the 1985 Geologic Map of North Carolina, lignitic clay, thin beds of fine-grained micaceous sand, and thick lenses of cross-bedded sand crop out around the site area. According to the well logs for monitoring wells MW-6 and MW-7, silty sand or fine sand underlies the site to approximately three feet BLS. Silty clay is present from three to 13 feet BLS. Fine to medium sand was observed at further depths up to 22 feet BLS. 5.2 HYDROGEOLOGY Groundwater - The 2020 Visual Hydrogeologic Framework (VHF) – North Carolina Hydrogeological Database identified sufficient boreholes near the site in order to draw a cross-section. According to the VHF, the surficial aquifer may extend to 20 feet below land surface (BLS). The Black Creek confining unit (10 feet thick) and aquifer are projected from 20 to 50 feet BLS. The Upper Cape Fear confining unit (approximately 40 feet thick) underlies the Black Creek aquifer. The Upper Cape Fear aquifer extends from approximately 190 to 300 feet BLS. Crystalline basement is expected to be encountered at 300 feet BLS in the site vicinity. Surface Water – A drainage ditch is located approximately 200 feet north- northeast of the site (S&ME, 2019A). It’s identified on the United States NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 8 June 2023 Geological Survey (USGS) Topographic Map as an unnamed intermittent tributary. 6.0 SITE ASSESSMENT INFORMATION CATLIN conducted field activities in general accordance with the approved TA and pre-prepared HASP. Upon arrival at the site, potential hazards were evaluated before beginning field work and are documented on electronic Job Hazard Analysis (JHA) forms. The JHA forms are included in Appendix C. Photographs from the site visits are included in Appendix B. Well locations and site features are shown on Figure 3 and well construction details are presented in Table 3. 6.1 MONITORING WELL INSTALLATION On February 1, 2023, two borings were advanced to 20 feet BLS (MW-5 and MW-7) and one to 22 feet BLS (MW-6) for monitoring well construction by a North Carolina Certified Well Contractor, utilizing hollow stem augers and a Diedrich D-50 drill rig. Cuttings generated during drilling activities were spread on-site. All wells were installed to 20 feet BLS. The wells (MW-5, MW-6, and MW-7) were constructed of new, threaded PVC casing and screen. No glues or cements were used in joining PVC components. New nitrile gloves were worn while handling all well materials. The monitoring wells were constructed with a pointed PVC sediment trap, 15 feet of 2-inch diameter, 0.010-inch slotted PVC well screen and approximately five feet of 2-inch diameter solid PVC riser to the surface. The annular space was filled with coarse sand pack to approximately two feet above the well screen in MW-5 and MW-6 and one foot above the well screen in MW-7. Bentonite chips were added to within one foot of the ground surface. The bentonite chips were poured from the surface while simultaneously pouring water to facilitate hydration. The wells were finished with a concrete pad and flush-mount steel wellhead and locking well cap. After installation, the monitoring wells were developed by over-pumping. The TOC elevations were surveyed using traditional methods (Rod and Level) in reference to a preexisting monitoring well with a known elevation (MW-2). Monitoring well construction information is summarized in Table 3 and a site map with monitoring well location is illustrated on Figure 3. Site photographs are presented in Appendix B. The well logs and Well Construction Records were submitted to NCDEQ on February 3, 2023; copies are provided in Appendix D. 6.2 MMPE EVENT CATLIN mobilized to the site on April 10 and 14, 2023 to supervise a MMPE event conducted by EEM. Prior to the event, CATLIN personnel gauged MW-5, MW-6, and MW-7 and the average DTW was approximately 16.4 feet NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 9 June 2023 below top of casing (BTOC). LNAPL was not measured in any of the monitoring wells. Gauging results are included in Table 3. The MMPE event was conducted for a duration of 96 hours, ending on April 14, 2023. Monitoring wells MW-5, MW-6, and MW-7 were utilized as extraction points. A total of 14,382 gallons of impacted groundwater was removed from the subsurface. A calculated 6,163.82 pounds of petroleum vapors were emitted during this event, equivalent to approximately 986.21 gallons of petroleum. The average rate of fluid recovery was 149.81 gallons per hour. There was no measurable thickness of LNAPL following the event. The MMPE report from EEM, including waste manifests and emissions calculations, is included in Appendix E. 6.3 GAUGING DATA Historical gauging results show DTW ranging from 8.00 feet BTOC (MW-1) to 17.18 feet BTOC (MW-1). Historical groundwater flow direction was towards the southwest (S&ME, 2019B; CATLIN, 2022). CATLIN conducted multiple gauging events during this monitoring period. During each event, DTW was measured using an electronic water interface probe. To prevent cross contamination, the probe and cabling were decontaminated according to the manufacturer’s recommendations between use in each well. Gauging data were recorded on an electronic groundwater sampling form using a tablet device. Gauging procedures were performed in general accordance with North Carolina Department of Environmental and Natural Resources (NCDENR) and NCDEQ Guidelines, and Environmental Protection Agency (EPA) Region 4 Operating Procedures. Prior to drilling for monitoring well installation on February 1, 2023, three monitoring wells (MW-1, MW-3, and MW-4) were gauged. The DTW was measured at 17.26 feet BTOC (MW-1), 12.80 feet BTOC (MW-3), and 15.53 feet BTOC (MW-4). LNAPL was not detected in any of the wells. After monitoring well installation, the three new monitoring wells (MW-5, MW-6, and MW-7) were gauged on February 2, 2023. The depths to water were measured at 18.21 feet BTOC (MW-5), 17.92 feet BTOC (MW-6), and 18.42 feet BTOC (MW-7). LNAPL was measured in all the monitoring wells; 0.61 feet thick in MW-5, 0.66 feet thick in MW-6, and 0.66 feet thick in MW-7. Approximately one month following the MMPE, on May 11, 2023, CATLIN personnel gauged all on-site monitoring wells (MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, and MW-7). The DTW ranged from 13.39 feet BTOC (MW-3) to 16.00 feet BTOC (MW-7). LNAPL was not encountered during this event. Based on groundwater elevations calculated for this gauging event, groundwater flow direction is towards the north-northeast. NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 10 June 2023 Monitoring well gauging results for events conducted by CATLIN are presented in Table 3. The groundwater elevation is illustrated on Figure 4 and groundwater sampling forms are provided in Appendix C. 6.4 SAMPLING DATA Following gauging, the monitoring wells were sampled in general accordance with NCDENR and NCDEQ Guidelines, and EPA Region 4 Operating Procedures. Prior to obtaining a representative groundwater sample, the monitoring wells were purged by removing a minimum of three well volumes using a new, disposable bailer. Monitoring well groundwater field parameter data were measured at one-minute intervals using an In-Situ Aqua TROLL 600 Multiparameter Sonde (Aqua TROLL). Conductivity, pH, oxidation reduction potential (ORP), dissolved oxygen, and temperature measurements were recorded utilizing the VuSitu mobile application (version 1.17.12). Groundwater parameter data were transferred from the VuSitu mobile application to the electronic groundwater sampling forms. Copies of the groundwater sampling forms are available in Appendix C. After a minimum of three well volumes were removed (or the well was bailed dry), a groundwater sample was collected from each well and poured into appropriate pre-preserved laboratory-provided glassware, labeled, and placed on ice in an insulated cooler. A laboratory-provided trip blank was maintained in the cooler for the duration of the event. The groundwater samples and laboratory-provided trip blank were submitted to Con-Test Analytical Laboratory (Certification NC 652 and NC-DW 25703) in East Longmeadow, Massachusetts, under proper chain of custody (COC) protocol and analyzed per SM 6200B (including EDB, MTBE, and DIPE). The laboratory analytical data and COC are included in Appendix F. 6.5 SUMMARY OF GROUNDWATER INFORMATION Historically, samples from monitoring well MW-1 have contained the highest petroleum constituent concentrations. LNAPL has previously been detected at this site in MW-2 ranging from 0.3 feet thick (December 7, 2018) to 1.44 feet thick (December 18, 2018). During the previous sampling event conducted by CATLIN (November 2022), the sample from MW-1 did not have any contaminants at concentrations above 2L GWQS. No petroleum constituents have been historically detected at concentrations above GCL (S&ME, 2019A; CATLIN, 2021). The latest groundwater sampling laboratory results for SM 6200B analysis are summarized in Table 4. Historical results for events conducted by CATLIN are in Table 5. Monitoring well sample analytical results are illustrated on Figure 5. Historical groundwater sampling results are provided in Appendix A. A copy of the complete laboratory report and COC documentation are in Appendix F. NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 11 June 2023 Monitoring Wells During the May 2023 monitoring event, six monitoring well groundwater samples (MW-1, MW-3, MW-4, MW-5, MW-6, and MW-7) were collected and submitted for analysis via SM 6200B (including EDB, MTBE, and DIPE). Laboratory analysis did not detect any constituents above their respective reporting limits in the samples from MW-3 and MW-4. No analyte concentrations were detected above GCL in any of the monitoring well samples. Analytical results reported the following constituents at concentrations above their 2L GWQS in samples MW-1, MW-5, MW-6, and MW-7: • MW-1: n-butylbenzene, sec-butylbenzene, isopropylbenzene, p- isopropyltoluene, 1,2,4-trimethylbenzene, and 1,3,5- trimethylbenzene; • MW-5: benzene, n-butylbenzene, ethylbenzene, isopropylbenzene, p-isopropyltoluene, MTBE, naphthalene, n-propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and total xylenes; • MW-6: n-butylbenzene, sec-butlybenzene, ethylbenzene, isopropylbenzene, p-isopropyltoluene, naphthalene, n-propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and total xylenes; and • MW-7: benzene, n-butylbenzene, ethylbenzene, isopropylbenzene, MTBE, naphthalene, n-propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and total xylenes. Trip Blank One laboratory-provided trip blank sample was submitted for analysis per SM 6200B (including EDB, MTBE, and DIPE). No targeted analytes were detected in the sample. 6.6 EVALUATION OF ASSESSMENT INFORMATION Extent of Contamination Several petroleum constituents were detected above their respective 2L GWQS in samples from MW-1, MW-5, MW-6, and MW-7. However, no constituents were reported above GCL. A summary of monitoring well groundwater sample analytical results are illustrated on Figure 5.

NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 12 June 2023 Cleanup Levels Achieved Soil – To date, approximately 614.18 tons of impacted soil have been removed from the site. Soil samples obtained in 2019 revealed TPH GRO and DRO concentrations up to 12,000 mg/kg and 870 mg/kg, respectively. Risk-based soil sample analytical results have not been obtained (S&ME, 2019B). Groundwater – Groundwater contaminant concentrations are above 2L GWQS but below GCL at the site. LNAPL – Prior to the MMPE, LNAPL was measured in monitoring wells MW-5, MW-6, and MW-7 (up to 0.66 feet thick). However, LNAPL was not encountered one month after the MMPE. LNAPL has been periodically measured at the site since 2018. 7.0 CONCLUSIONS AND RECOMMENDATIONS Conclusions Groundwater monitoring findings for this period are summarized below: •Gauging events were conducted prior to drilling, approximately 24 hours after well installation, before and after the MMPE event, and prior to sampling. •Three Type II monitoring wells (MW-5, MW-6, and MW-7) were installed to20 feet BLS. •Approximately 24 hours after well installation, LNAPL was measured in MW-5 (0.61 feet), MW-6 (0.66 feet), and MW-7 (0.66 feet). •A MMPE was conducted utilizing monitoring wells MW-5, MW-6, and MW-7as extraction points. A total of 14,382 gallons of impacted groundwater and LNAPL were recovered. A calculated 6,163.82 pounds of petroleum vapors were removed, equivalent to 986.21 gallons of petroleum. •Groundwater samples were collected from six monitoring wells (MW-1,MW-3, MW-4, MW-5, MW-6, and MW-7). •LNAPL was not observed in any of the monitoring wells during sampling. •No analyzed compound concentrations were detected above their respective2L GWQS in the MW-3 and MW-4 samples. •Several petroleum constituents were above their respective 2L GWQS in thesamples from MW-1, MW-5, MW-6, and MW-7. However, none were aboveGCL. •Contaminant concentrations in samples from MW-1 have increased since theprevious sampling event in November 2022. NCDEQ; 42022_Hall's Store CATLIN Engineers and Scientists CATLIN Project No. 220284 13 June 2023 Recommendations CATLIN recommends attempting to obtain access for sampling WSW-1, WSW-4 and WSW-7 and conducting another mobile multi-phase extraction (MMPE) event followed by a monitoring/sampling event. 8.0 STATEMENTS AND CERTIFICATION 1 Enter the date the monitoring report was due.
