(Progress) was contracted by Eden Oil Company, Inc. to conduct groundwater monitoring activities at the Pagetown Exxon located at 8035 Cherry Grove Road in Reidsville, Cawell County, North Carolina. The site consists of a convenience store which stores petroleum products in underground storage tanks (USTs) and aboveground storage tanks (ASTs) for retail sale. Formerly kerosene and diesel fuel were stored in USTs. The kerosene and diesel fuel USTs were removed following the discovery of a release in 2014. Three active USTs are present at the site and used to store gasoline. The site is located in a commercial and residential area of rural Caswell County. The surrounding properties are served by water-supply wells within 1,500 feet of the source area. Progress previously completed an Initial Abatement Action Report, dated July 24, 2014; a Phase II Limited Site Assessment (LSA), dated November 26, 2014; a Free Product Recovery and Water-Supply Sampling Report dated May 8, 2015; and, a Water-Supply Well Sampling Report, dated July 31, 2015. The NCDEQ issued a Notice of Regulatory Requirements (NORR), dated December 4, 2014, requiring that a Comprehensive Site Assessment (CSA) be completed for the site. Following discussions with the NCDEQ, it was determined that prior to completing a CSA, free product recovery activities were to be performed and the nearby water-supply wells sampled. A CSA was submitted to the NCDEQ on August 20, 2015. • On June 2, 2017 Progress supervised the installation of monitoring well MW-9 in a downgradient location from the documented release. • Progress was on site on June 20, 2017 to collect groundwater samples from monitoring wells MW-2 through MW-9, DW-1, and DW-2 and from water-supply wells WSW-1, WSW-5, WSW-6, WSW-14, and WSW-20. • A groundwater sample was not collected from monitoring well MW-1, as approximately 2.00 feet of free product were measured in the well at the time of gauging. • Laboratory analysis of the groundwater samples collected from monitoring wells MW-3, MW-6, MW-8, MW-9, DW-1, and DW-2 did not detect targeted compounds above their respective NC2LGWQS. Laboratory analysis of the groundwater samples collected from monitoring wells MW-2, MW-4, MW-5, and MW-7 detected targeted compounds above their respective NC2LGWQS. • Laboratory analysis of water samples collected from water-supply wells WSW-1, WSW-5, WSW-6, and WSW-20 did not detect targeted compounds above their respective NC2LGWQS or US EPA Drinking Water Standards. • Laboratory analysis of the groundwater sample collected from water-supply well WSW-14 detected benzene and 1,2-dichloroethane at concentrations that exceed their respective NC2LGWQS. Please note, the concentrations detected in the water sample collected from water-supply well WSW-14 do not exceed the applicable US EPA Drinking Water Standards. Based on the remaining concentrations in select groundwater samples exceeding their respective NC2LGWQS, Progress recommends the following: Groundwater Monitoring Report Pagetown Exxon Reidsville, Caswell County, North Carolina Progress Project 1017126.001 December 1, 2017 3 • Progress recommends having discussions with the NCDEQ to determine corrective action goals and acceptable remediation strategies.

The site consists of a convenience store which stores petroleum products in underground storage tanks (USTs) and aboveground storage tanks (ASTs) for retail sale. Formerly kerosene and diesel fuel were stored in USTs. The kerosene and diesel fuel USTs were removed following the discovery of a release in 2014. Three active USTs are present at the site and used to store gasoline. The site is located in a commercial and residential area of rural Caswell County. The surrounding properties are served by water-supply wells within 1,500 feet of the source area. Progress previously completed an Initial Abatement Action Report, dated July 24, 2014; a Phase II Limited Site Assessment (LSA), dated November 26, 2014; a Free Product Recovery and Water- Supply Sampling Report dated May 8, 2015; and, a Water-Supply Well Sampling Report, dated July 31, 2015. The NCDEQ issued a Notice of Regulatory Requirements (NORR), dated December 4, 2014, requiring that a Comprehensive Site Assessment (CSA) be completed for the site. Following discussions with the NCDEQ, it was determined that prior to completing a CSA, free product recovery activities were to be performed and the nearby water-supply wells sampled. A CSA was submitted to the NCDEQ on August 20, 2015. A description of the former UST systems is listed in Table B-1 below. Figure 2 depicts the site and the location of the monitoring wells.

The rocks beneath the site have been characterized as metamorphosed granitic rocks. Groundwater generally is stored in the pore space between individual grains of residual soil and in the fractures within the underlying parent rock. Due to the intense shearing associated with the thrust faulting in the area and the relatively shallow depths to bedrock, it can be expected that the fractures play a major role in the flow of groundwater in the subsurface. Recharge to the water table is primarily by precipitation infiltrating the upper soils and percolating downward, under the influence of gravity, to the groundwater table. Typically, the water table is not a level surface, but a subdued reflection of the land surface. However, the depth to the water table is not constant, and depends on many factors, which include the amount of rainfall, the permeability of the soil, and the amount of groundwater being pumped in the area. Site Geology and Hydrogeology Based on our review of the topographic map and on-site observation, the site is located near the top of a northeast-southwest trending ridge. Groundwater generally flows in directions sub- parallel to the ground surface slopes and under the influence of gravity toward points of discharge such as creeks, swamps, drainage swales, or pumped groundwater wells. Based on topographic inference, groundwater beneath the site most likely flows to the southwest. An unnamed pond is located approximately 1,300 feet toward the southwest as shown on the topographic map (Figure 1). Determination of Groundwater Flow Direction Based on our review of the topographic map and on-site observation, the site is located on an east- west trending ridge. Groundwater generally flows in directions sub-parallel to the ground surface slopes and under the influence of gravity toward points of discharge such as creeks, swamps, drainage swales, or pumped groundwater wells. Based on topographic inference, groundwater beneath the site most likely flows to the southwest toward an intermittent tributary of Stony Creek (Figure 1). Based on the excavation and drilling activities at the site, the soil beneath the site consists predominately of a silty to sandy clay material. As presented in the Comprehensive Site Assessment, the hydraulic conductivity was calculated as 0.70 ft/day and the groundwater flow velocity was calculated as 0.056 ft/day. Free Product Measurements Approximately 0.69 feet of free product were measured in monitoring well MW-1 during the LSA sampling event on November 11, 2014. Groundwater Monitoring Report Pagetown Exxon Reidsville, Caswell County, North Carolina Progress Project 1017126.001 December 1, 2017 7 On March 9, 2015, Progress gauged free product in monitoring well MW-1 prior to the MMPE event. Approximately 2.92 feet of free product were measured in monitoring well MW-1. On April 13, 2015 Progress returned to the site to sample the surrounding water-supply wells and gauge groundwater/free product levels in monitoring well MW-1, as appropriate. Approximately 1.71 feet of free product were measured in monitoring well MW-1. Approximately 5.10 feet of free product were measured in monitoring well MW-1 during a water- supply well sampling event on July 6, 2015. Approximately 5.55 feet of free product were measured in monitoring well MW-1 during the CSA sampling event on August 3, 2015, and 0.80 feet on March 15, 2016. On September 8, 2016 Progress returned to the site to sample the existing monitoring wells and gauge water/free product levels in the monitoring wells, as appropriate. Approximately 0.44 feet of free product were identified in monitoring well MW-1. On June 20, 2017 Progress returned to the site to sample the existing monitoring wells and gauge water/free product levels in the monitoring wells, as appropriate. Approximately 2.00 feet of free product were identified in monitoring well MW-1. Monitoring Well Installation One Type II permanent monitoring well (MW-9, Figure 2) was installed in the approximate location requested by the NCDEQ using a truck-mounted drill rig and hollow-stem augers on June 2, 2017 by 3D Environmental Investigations, LLC. The monitoring well was installed at the request of the NCDEQ to determine the horizontal extent of the impacted groundwater beneath the site. Monitoring well MW-9 was installed to an approximate depth of 30 feet below land surface with a fifteen-foot screened interval. Well construction information is provided in Table B-7. The Non-Residential Well Construction Record and boring log are included in the Appendix. Groundwater Sampling Activities Progress was on site on June 20, 2017 to collect groundwater samples from monitoring wells MW- 2 through MW-9 and DW-1 and DW-2. Water samples were also collected from water-supply wells WSW-1, WSW-5, WSW-6, WSW-14, and WSW-20. A groundwater sample was not collected from monitoring well MW-1, as approximately 2.00 feet of free product were measured in the well at the time of gauging. Prior to sampling, the wells were developed until the development water ran relatively clear, and the well was purged of an additional three casing volumes of water prior to sampling. The depth to the groundwater surface in each of the wells was measured prior to well purging using a decontaminated electric sounder. The wells were surveyed by Progress using a relative benchmark that was arbitrarily given an elevation of 100 feet (top of casing of monitoring well MW-3). The elevations of the monitoring wells and the groundwater surface are both relative to that benchmark. The relative groundwater elevations are shown in Table B-7. The relative groundwater elevations are depicted on Figure 3. Well construction information is provided in Table B-7. Groundwater Monitoring Report Pagetown Exxon Reidsville, Caswell County, North Carolina Progress Project 1017126.001 December 1, 2017 8 The groundwater samples were decanted into laboratory-supplied bottles and placed into a cooler packed with ice. The cooler was delivered under chain-of-custody to Research and Analytical Laboratories, Inc. (R&A) in Kernersville, North Carolina for testing. R&A analyzed the groundwater samples for VOCs by Standard Method 6200B. A summary of the groundwater sample analytical results is included in Table B-4. • Laboratory analysis of the groundwater samples collected from monitoring wells MW-3, MW-6, MW-8, MW-9, DW-1, and DW-2 did not detect targeted compounds at concentrations exceeding their respective NC2LGWQS. Laboratory analysis of the water samples collected from water-supply wells WSW-1, WSW5, WSW-6, and WSW-20 did not detect targeted compounds at concentrations exceeding their respective NC2LGWQS or the applicable US EPA Drinking Water Standards. • Laboratory analysis of the groundwater sample collected from monitoring well MW-2 detected benzene (38.3 ug/L), 1,2-dichloroethane (1.12 ug/L), naphthalene (105 ug/L), 1,2,4-trimethylbenzene (421 ug/L), and total xylenes (807 ug/L) at concentrations exceeding their respective North Carolina 2L Groundwater Quality Standards (NC2LGWQS). • Laboratory analysis of the groundwater sample collected from monitoring well MW-4 detected naphthalene (22.8 ug/L) at a concentration exceeding its NC2LGWQS. • Laboratory analysis of the groundwater sample collected from monitoring well MW-5 detected benzene (3,550 ug/L), ethylbenzene (3,260 ug/L) isopropylbenzene (118 ug/L), IPE (686 ug/L), MTBE (4,690 ug/L), naphthalene (530 ug/L), n-propylbenzene (418 ug/L), toluene (34,700 ug/L), 1,2,4-trimethylbenzene (2,260 ug/L), 1,3,5-trimethylbenzene (960 ug/L), and total xylenes (18,000 ug/L) at concentrations exceeding their respective NC2LGWQS. • Laboratory analysis of the groundwater sample collected from monitoring well MW-7 detected MTBE (63.6 ug/L) at a concentration that exceeds its NC2LGWQS. • Laboratory analysis of the groundwater sample collected from water-supply well WSW-14 detected benzene (3.05 ug/L) and 1,2-dichloroethane (1.46 ug/L) at concentrations that exceed their respective NC2LGWQS. Please note, the concentrations detected in the water sample collected from water-supply well WSW-14 do not exceed the applicable US EPA Drinking Water Standards. The laboratory analytical reports for the groundwater samples are provided in the Appendix. The laboratory test results are summarized on Figure 5. Maps depicting the plumes of benzene, BTEX, and MTBE concentrations are included on Figures 6 through 8, respectively. F FREE PRODUCT REMOVAL Progress completed a free product recovery event using mobile, multi-phase extraction (MMPE) on March 9 to March 13, 2015. Free product and groundwater were extracted from monitoring Groundwater Monitoring Report Pagetown Exxon Reidsville, Caswell County, North Carolina Progress Project 1017126.001 December 1, 2017 9 well MW-1. The event extracted approximately 1,883 gallons of impacted groundwater and 96.060 pounds or 15.36 gallons of product as vapor. G MONITORED NATURAL ATTENUATION/NATURAL SOURCE ZONE DEPLETION STATUS Progress was on site on June 20, 2017 to collect groundwater samples from monitoring wells MW- 2 through MW-9, DW-1, and DW-2 and from water-supply wells WSW-1, WSW-5, WSW-6, WSW-14, and WSW-20. A groundwater sample was not collected from monitoring well MW-1, as approximately 2.00 feet of free product were measured in the well at the time of gauging. Based on the results of the laboratory testing, Progress makes the following observations: • Laboratory analysis of the groundwater samples collected from monitoring wells MW-3, MW-6, MW-8, MW-9, DW-1, and DW-2 did not detect targeted compounds above their respective NC2LGWQS. Laboratory analysis of the groundwater samples collected from monitoring wells MW-2, MW-4, MW-5, and MW-7 detected targeted compounds above their respective NC2LGWQS. • Laboratory analysis of water samples collected from water-supply wells WSW-1, WSW-5, WSW-6, and WSW-20 did not detect targeted compounds above their respective NC2LGWQS or US EPA Drinking Water Standards. • Laboratory analysis of the groundwater sample collected from water-supply well WSW-14 detected benzene and 1,2-dichloroethane at concentrations that exceed their respective NC2LGWQS. Please note, the concentrations detected in the water sample collected from water-supply well WSW-14 do not exceed the applicable US EPA Drinking Water Standards. The groundwater contaminant plume appears to be migrating to the southwest in the direction of the calculated groundwater flow direction. Based on the groundwater data, there appears to be a possible off-site source to the northeast. According to information provided to Progress a gasoline station was formerly located on the property to the east. Groundwater concentrations detected in the groundwater samples collected from monitoring wells do not appear to have an increasing or decreasing trend. A source area of both soil and groundwater contamination appears to be located in close proximity to the current dispenser location (and likely former dispenser location). Without the implementation of a remedial strategy, Progress does not expect to observe a dramatic decrease in the groundwater contaminant concentrations. The groundwater contaminant plume appears to be reasonably defined; however, without active groundwater remediation the contaminant plume would be expected to continue migrating to the southwest. Please note, the current UST system does not appear to be the source of the contamination. H CONCLUSIONS Based on the results of the groundwater sampling event, Progress makes the following conclusions: • On June 2, 2017 Progress supervised the installation of monitoring well MW-9 in a downgradient location from the documented release.
