EIT – Engineer in Training Principal Engineer Monitoring Report August 15, 2023 (Former) 321 Mini Mart Incident No. 36228 Lincolnton, North Carolina Excel No. 27010 EXCEL CIVIL & ENVIRONMENTAL ASSOCIATES, PLLC www.excelengr.com PROJECT SUMMARY  Groundwater quality samples were collected from four monitoring wells (MW-2R, MW- 3R, MW-6 and VW-1) on June 14 and 15, 2023, and laboratory analyzed for volatile organic compounds (VOCs) by EPA Method 6200B, Ethylene Dibromide (EDB) and by EPA Method 504.1. During the site visit, free product was observed in MW-1R. Static water levels were collected with a decontaminated water level indicator. Additionally, the four monitoring wells were also analyzed for natural attenuation parameters (alkalinity, free carbon dioxide, nitrate/sulfate, total organic carbon, iron/manganese, and methane).  During the sampling event, free product was observed in MW-1R. Excel returned to the property the following day and gauged the thickness at 0.69 feet. Additionally, VW-1 had a strong petroleum odor. Monitoring well MW-1R has not historically shown free product.  The onsite remediation system was put into operation on November 11, 2009. The air sparging and soil vapor extraction system is comprised of nine injection wells and seven vapor extraction wells. The system was shut down on August 31, 2015 per DWM directive.  The results of the laboratory data for constituents which exceeded the NCAC 2L Standards are as follows:  Benzene: MW-2, MW-3R, MW-6 and VW-1  Xylenes: VW-1  Naphthalene: MW-2R, MW-6 and VW-1  1,2,4-Trimethylbenzene: VW-1 Copies of the laboratory analytical results are included in Appendix E. Natural attenuation data is provided in Table 5.  Results of past receptor surveys completed by Excel during assessment activities indicate that twenty-nine supply wells were identified within 1,500 feet of the property, four of which are located within 1,000 feet and confirmed as being utilized for drinking water purposes. According to the USGS Topographical Map the nearest surface water body is an unnamed tributary of Walker Branch, located approximately 800 feet southeast of the source area. DISCUSSION  Excel conducted a Mann-Kendall constituent trend analysis which relies on three statistical metrics, an “S” statistic which indicates whether concentration trend vs. time is generally decreasing or increasing; a confidence factor (CF) which modifies the S statistic to indicate the degree of confidence in the trend result; and a coefficient of variation (COV) to distinguish describe the variability in the data set. The analysis included an evaluation of both the overall reductions in the areal extent and plume length for constituents of concern as well as an evaluation of the stability of the plume constituent concentrations for monitor wells in the core and leading edge of the plume. Monitoring Report August 15, 2023 (Former) 321 Mini Mart Incident No. 36228 Lincolnton, North Carolina Excel No. 27010 EXCEL CIVIL & ENVIRONMENTAL ASSOCIATES, PLLC www.excelengr.com Mann-Kendall graphs are provided in Appendix C. The graphs depict concentration trends for monitoring wells MW-1, MW-2 MW-3, MW-6 and VW-1 and indicated the following: o Benzene:  Increasing: MW-1R;  No Trend: MW-3R, MW-6, VW-1;  Decreasing: MW-2R o Toluene:  No Trend: MW-1R;  Decreasing: MW-2R, MW-3R o Ethylbenzene:  Increasing: MW-1R;  No Trend: MW-3R;  Decreasing: MW-2R, MW-6 o Xylenes:  No Trend: MW-1R, MW-3R;  Decreasing: MW-2R, MW-6 o MTBE:  No Trend: MW-1R;  Decreasing: MW-2R, MW-3R, MW-6, VW-1 o Naphthalene:  No Trend: MW-1R;  Increasing: VW-1  Decreasing: MW-2R, MW-3R, MW-6 RECOMMENDATIONS Based on the results of the sampling event, a new release appears likely at the subject property. The current UST system should be evaluated, and repairs should be made as they are discovered. Excel recommends a full monitoring round be conducted. Adjacent water supply wells should also be sampled to verify no impact on potential receptors in the vicinity of the property. A groundwater quality sampling event is proposed for October of 2023 as approved by NCDEQ. Monitoring Report August 15, 2023 (Former) 321 Mini Mart Incident No. 36228 Lincolnton, North Carolina Excel No. 27010 EXCEL CIVIL & ENVIRONMENTAL ASSOCIATES, PLLC www.excelengr.com PROJECT INFORMATION PRIMARY CONSULTANT: Excel Civil & Environmental Associates, PLLC PROJECT MANAGER: Aaron Lon , PE SITE CONTACT: Mr. Satish Desai SITE HISTORY: Excel completed a Phase II ESA at the subject site as part of a pre-purchase assessment in February-March 2007. The laboratory results from the soil samples indicated contamination levels exceeding regulatory action levels. Excel completed a Site Check at the site in April 2007. At the request of the NCDEQ Excel completed a Phase II LSA. Groundwater samples collected as part of the LSA activities revealed contamination levels which exceeded NCAC 2L Standards. Additionally, Excel identified twenty-eight (28) water supply wells within 1,500 feet of the subject site. A CSA was completed by Excel in September 2008 defining the horizontal and vertical extent of both soil and groundwater contamination. In response to a letter received from NCDEQ, Excel prepared and submitted a Corrective Action Plan in January 2009. As per the approved CAP, Excel installed and started operation of the air sparge and vapor extraction remediation system in November 2009. The system was shut down on Au ust 31, 2015. SURFICIAL AND REGIONAL GEOLOGY: The subject site is located within the Chauga Belt of the Inner Piedmont Physiographic Province of North Carolina. The 1985 USGS Geologic Map of North Carolina indicates this area as being underlain by mica schists with other micaceous metamorphic rock and cherryville granite rock. During the completion of the monitoring wells at the property, a brown to orange, silt-clay mixture (CL) was observed from approximately 1-fbgl to 22-fbgl. Partially weathered rock (PWR) was encountered from approximately 22-fbgl to 50-fbgl. The type of soils observed locations appears consistent with the surficial sediments common for this area. SURFICIAL HYDROLOGY: Groundwater flow across the site appears to be following with the general topography and flowing to the south in a direction towards MW-14 and MW-15. The average hydraulic gradient across the site is approximately 2.46 feet per day (ft/day). The average groundwater velocity was calculated to be approximately 0.08 ft/day (29.2 ft/year). As such, the lateral migration of dissolved petroleum constituents appears to be impeded by the local geological/hydrogeological conditions.

Milestones are defined in the CAP. Label column headers with a representative title (‘Active Y1’, ‘MNA Yr 5’ etc.) Add sheets/columns as needed to more effectively track progress. Interim Reporting Tables 2. Calculate the measured mass for each unit by multiplying the analytical result by the representative volume (weight, pore space, etc.). (See https://www3.epa.gov/region02/rcra/ra2.pdf) 3. Calculate removed amounts based on excavation screening and/or system effluent monitoring, multiplied by total volume excavated or the system throughput during that period. 4. Where measured from sampling/screening in situ, use the total Measured Mass. Where not screened (or if not representative), use prior Total Mass less current Total Mass Removed. 5. This equals the % reduction from the prior mass (current Total Mass ÷ prior Total Mass). Very large negative values may indicate a new contribution and may require investigation. 6. This equals the current mass reduction % progress (1 - (Revised Total Mass ÷ Applicable Milestone)). Zero or positive values indicate that the associated milestone has been reached EXCEL CIVIL & ENVIRONMENTAL ASSOCIATES, PLLC www.excelengr.com APPENDIX E - LABORATORY ANALYSES & CHAIN OF CUSTODY FORM #=CL# July 05, 2023 LIMS USE: FR - DONNA FARRIS LIMS OBJECT ID: 92672791 92672791 Project: Pace Project No.: RE: Donna Farris Excel Civil & Environmental Assoc. 625 Huntsman Ct.

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. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute.
