Comprehensive Site Assessment Report Prepared on: October 9, 2023 Former Rushco Food Store #4 Project Manager: Samuel McKay III, P.G. GRI Project No. 5721 i EXECUTIVE SUMMARY Former Rushco Food Store #4 is located at 1901 West Innes Street in Salisbury, Rowan County, North Carolina The property operates as a petroleum retail facility and convenience store. The site is covered by concrete and asphalt. There are two 10,000-gallon gasoline USTs and one 7,500-gallon gasoline UST currently in use at the site with three associated gasoline dispensers. The surrounding properties are commercial, residential, and institutional. According to the information determined during receptor survey activities, no water supply wells were identified within 1,500 feet of the site. Public water is available to the site and surrounding properties within a 1,500-foot radius of the site. During due diligence activities conducted in October 2021, reportable soil violations were identified at the site, and an LSA was required by the NCDEQ A receptor survey was conducted on March 14, 2022. No water supply wells were identified within a 1,500-foot radius of the site. No surface water bodies were identified within a 500-foot radius of the site. On March 14, 2022, one Type II monitoring well was installed and sampled as part of the LSA activities. Based on the results of the LSA activities, an ARA was negotiated to be conducted prior to the CSA directed by the NCDEQ. ARA activities were conducted between February 20, 2023 and March 1, 2023. Three Type II monitoring wells and one Type III telescoping well were installed and sampled, soil samples were collected during the installation of the wells and submitted for laboratory analysis, and slug tests were conducted on two of the monitoring wells and the telescoping well as part of the ARA activities. Based on the results from the ARA activities, a CSA was requested by the NCDEQ. On August 11, 2023, three Type II monitoring wells were installed as part of the CSA activities. After the new wells were installed, a comprehensive sampling event was conducted. On August 24, 2023, seven Type II monitoring wells and one Type III telescoping well were gauged, purged, and sampled. The reported contaminant concentrations of benzene, toluene, ethylbenzene, xylenes, MTBE, naphthalene, tert-amyl alcohol (TAA), tert-butyl alcohol (TBA), 2-hexanone, isopropylbenzene, MIBK, n-propylbenzene, IPE, styrene, 1,2,4-triethylbenzene, 1,3,5-trimethylbenzene, lead, C5-C8 aliphatics, C9-C12 aliphatics and/or C9-C10 aromatics in the ground water samples collected from MW-1 through MW-7 exceeded the MACs. The reported benzene, TAA and TBA contaminant concentrations in the ground water sample collected from MW-1 exceeded the GCLs. The reported benzene contaminant concentration in the ground water sample from MW-4 exceeded the GCL. No free product was encountered at the site during the CSA activities. According to the 1985 Geologic Map of North Carolina, the site is located within the Charlotte Belt. The bedrock is generally described as interbedded felsic to mafic tuffs and flowrock. Based on observations made during the assessment activities, surficial soils observed at the site consist of various clays and silts ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Comprehensive Site Assessment Report Prepared on: October 9, 2023 Former Rushco Food Store #4 Project Manager: Samuel McKay III, P.G. GRI Project No. 5721 ii to varying depths, with lenses of weathered quartz. Ground water flow was generally toward the northeast. The horizontal hydraulic gradient calculated between MW-1 and MW-5 was 0.03 feet per foot. The vertical hydraulic gradient calculated between MW-1 and TW-1 was 0.02 feet per foot in the upward direction. The site risk classification has been deemed as intermediate risk based on the presence of GCL exceedances. Therefore, the ground water contamination must be remediated to concentrations less than the GCLs. A comprehensive ground water sampling event should be conducted at the site in March 2024 to confirm the results of the CSA ground water sampling events. MMPE events should be conducted on monitoring wells MW-1 , MW-4, and MW-6 to reduce contaminant concentrations in those wells. Based on the results of the March 2024 sampling event, a decision to pursue corrective action or allow for natural attenuation can be made. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

Seepage velocities, calculated using the equation V = k(dh/dl)/ne, ranged from 5.80 x 10-3 to 8.71 x 10-3 feet per day (2.12 to 3.18 feet per year). The average seepage velocity was 7.255 x 10-3 feet per day (2.65 feet per year). The hydraulic conductivity in the Type III monitoring well calculated using the Bouwer and Rice method was 3.126 x 10-4 feet per minute (0.4501 feet per day). The seepage velocity calculated for the Type III monitoring well was 4.50 x 10-2 feet per day (16.40 feet per year). A summary of the results of slug test analyses is presented in Table 8. 7.0 REGIONAL GEOLOGY AND HYDROGEOLOGY According to the 1985 Geologic Map of North Carolina, the site is located within the Charlotte Belt. The bedrock is generally described as interbedded felsic to mafic tuffs and flowrock. Based on observations made during the assessment activities, surficial soils observed at the site consist of various clays and silts to varying depths, with lenses of weathered rock. Ground water flow was generally toward the northeast. The vertical hydraulic gradient was upward. 8.0 SITE GEOLOGY AND HYDROGEOLOGY Based on observations made during assessment activities, surficial soils observed at the site consist of various clays, silts and sands to varying depths (approximately 7 to 28 feet) where weathered rock is encountered, grading into competent granitic rock. A summary of the current ground water gauging data is shown below: Well ID Screened Interval (x to y ft. BGS) Bottom of Well (ft. BGS) Top of Casing Elevation (ft.)

Depths to ground water in the Type II monitoring wells ranged from 21.96 to 25.38 feet below the tops of well casings. Ground water elevations at the site, based on an assumed datum of 100.00 feet, ranged from 74.74 to 77.41 feet. Ground water flow was generally toward the northeast. 9.0 DISCUSSION During due diligence activities conducted in October 2021, reportable soil violations were identified at the site, and an LSA was required by the NCDEQ. To date, seven Type II monitoring wells and one telescoping well have been installed to determine the horizontal and vertical extent of the release. Monitoring wells MW-1 and MW-4 contained the highest ground water contamination levels during the CSA activities with the GCLs below the reported concentrations of benzene, TBA and/or TAA. Please note that MW-1 and MW-4 are also in the vicinity of the UST basin and dispensers. Free product has not been present at the site during any phase of assessment. Based on the current risk ranking of the site, it was determined that the contaminant plume is sufficiently delineated. The risk ranking for the site has been established as intermediate due to GCL exceedances in the ground water. In order to lower the risk ranking of the site, ground water sampling should continue at the site until ground water concentrations are below GCLs. 10.0 CONCLUSIONS AND RECOMMENDATIONS  No further soil assessment should be required.  Ground water flow direction is to the northeast.  The ground water contaminant plume is defined to the level of GCL concentrations for the site specific cleanup goals.  Based on this site assessment, the site risk classification should remain intermediate.  MMPE events should be conducted on MW-1, MW-4, and MW-6 to reduce contaminants.  Ground water sampling should continue until ground water concentrations are below GCLs.  GRI recommends comprehensive ground water sampling should be conducted at the site in March 2024. Based on the results of the March 2024 sampling event, further recommendations can be made. 11.0 PUBLIC NOTICE Copies of the applicable portions of this CSA report have been forwarded to the appropriate local officials by certified mail.
