The property is currently developed with an automotive repair facility. In October of 1997, three 1,000-gallon gasoline USTs were removed from the site and a release was detected. Mark Creel & Associates, Inc. completed the UST closure activities and associated report. The release was confirmed through laboratory analysis of soil samples collected during the closure activities. Apex Environmental, Inc. completed an LSA for the site dated March 12, 2004. The site has been classified as an intermediate risk site based on the presence of benzene above its Gross Contaminant Level (GCL). Based on the intermediate risk classification of the site, the NCDEQ issued a Notice of Regulatory Requirements (NORR) dated February 13, 2023 requiring that an additional groundwater monitoring event be completed. Project information is based on correspondence between NCDEQ personnel, McLeod Oil Company, Inc. and Pilot and the previously completed activities. 1.1 UST Information A release was identified during the previous removal of three 1,000-gallon gasoline USTs by others in October 1997. UST information is summarized in Table 1. 2.0 SITE GEOLOGY AND HYDROGEOLOGY The United States Geological Survey (USGS) Topographic Map, Mebane and Efland, North Carolina Quadrangle depicts the site as an urban area (Drawing 1). The site elevation is approximately 670 feet above mean sea level. Unamend tributaries to Haw River are located approximately 1,670 feet southwest of the site. Based on the review of the USGS topographic map and observations of the general area and site topography, surface run-off would be expected to flow generally to the southwest across the site. The subject site is located within the Piedmont Physiographic Province. The Piedmont Physiographic Province generally consists of hills and ridges which are dissected by a system of swales and streams. The Piedmont Physiographic Province is predominantly underlain by metamorphic rock (formed by heat, pressure and/or chemical action) and igneous rock (formed directly from molten material). The topography and relief of the Piedmont Province has developed from differential weathering of the igneous and metamorphic rock. Ridges and hills have been developed in areas of less weathered rock. Because of the continued chemical and physical weathering rock in the Piedmont Physiographic Province is generally covered with a Groundwater Monitoring Report Dodson’s Amoco Pilot Project G-8098.1 March 7, 2023 2 mantle of soil that has weathered in place from the parent bedrock. These soils vary in thickness and are referred to as residuum or residual soils. The residuum is typically finer grained and has higher clay content near the surface because of the advanced weathering. Similarly, the soils typically become coarser grained with increasing depth because of decreased weathering. As the weathering decreases, the residual soils generally retain the overall appearance, texture and foliations of the parent rock. In general, groundwater movement in the Piedmont Physiographic Province is from higher to lower elevations. As such, the presumed direction of groundwater flow is generally to the south across the site. Based on the presumed groundwater flow direction, areas to the north are potentially up-gradient of the site. 3.0 FIELD ACTIVITIES The field activities were completed by Pilot on February 23, 2023. The field activities consisted of collecting groundwater samples from existing monitoring wells MW-1 through MW-4 and DW- 1 (Drawing 3). 3.1 Monitoring Well and Water Supply Well Sampling A groundwater sample was collected from existing monitoring wells MW-1 through MW-4 and DW-1 using a disposable bailer and new length of nylon string. Prior to sampling, approximately three well volumes were purged from the monitoring wells. The monitoring wells were purged to remove silt and sediment from the groundwater and collect a representative sample of groundwater. After the purging was completed, samples were collected in the sample containers provided by the laboratory. Pilot personnel wore a new pair of disposable nitrile gloves during purging and sampling. Each container was labeled and placed in a cooler containing ice to maintain the samples at approximately 4 Celsius. The samples were then transported to Pace Analytical (Pace) for chemical analysis. The groundwater samples collected were analyzed for volatile organic compounds (VOCs) using Standard Method 6200B. A chain of custody was maintained and is included in Appendix B. Isoconcentration maps for select compounds that exceed their respective 2L Standard are included as Drawings 5 through 15, respectively. Copies of the Monitoring Well Sampling Sheets are included in Appendix A. The depth to the groundwater surface in monitoring wells MW-1 through MW-4 and DW-1 was measured using a decontaminated water level indicator. The top of casing elevation for each well was surveyed relative to an arbitrary benchmark (MW-1) with an assumed elevation of 100.00 feet above mean sea level. The previously documented monitoring well elevations were utilized to prepare a potentiometric surface map (Drawing 4). The relative groundwater elevations collected from each monitoring well on February 23, 2023 are provided in Table 2. Based on data collected during the assessment activities, the groundwater flow direction appears to be generally toward the west-southwest beneath the site. Groundwater Monitoring Report Dodson’s Amoco Pilot Project G-8098.1 March 7, 2023 3 3.2 Water Supply Wells Visual evidence of water supply wells was not previously documented within 1,500 feet of the source area. 3.2 Groundwater Modeling Groundwater modeling has not been completed. 3.3 Free Product Investigation and Recovery Free product was not detected during this monitoring event. 4.0 LABORATORY ANALYTICAL RESULTS 4.1 Groundwater Sample Analysis Laboratory analysis of the groundwater samples collected from monitoring wells MW-1, MW-2, MW-3, MW-4 and DW-1 detected targeted compounds above their respective 2L Standards, with benzene exceeding its GCL in MW-2. A summary of the groundwater analytical results is presented in Table 4. Historical groundwater contaminant concentrations for select monitoring wells are presented in the graphs in Appendix A. The laboratory data sheets are included in Appendix B. 5.0 CONCLUSIONS Based on the results of the groundwater sampling, Pilot concludes the following:  Laboratory analysis of the groundwater samples collected from monitoring wells MW-1, MW- 2, MW-3, MW-4 and DW-1 detected targeted compounds above their respective 2L Standards, with benzene exceeding its GCL in MW-2.  The groundwater flow was calculated to be generally to the west-southwest.  It appears that natural attenuation is occurring, and it is Pilot’s opinion that monitoring activities should continue until the concentration of benzene decreases to below its GCL.  The inactive UST system on the site is planned for removal in the near future. Groundwater Monitoring Report Dodson’s Amoco Pilot Project G-8098.1 March 7, 2023 4 6.0 RECOMMENDATIONS Pilot recommends that the current property owner/responsible party submit a copy of this Groundwater Monitoring Report to the NCDEQ, UST Section for their review. A NORP will need to be recorded prior to a property transaction occurring. 7.0 QUALIFICATIONS OF REPORT The activities and evaluative approaches used in this assessment are consistent with those normally employed in assessment projects of this type.

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 EPA Method 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.
