Included in this report is a description of the field activities, the results obtained, and our conclusions and recommendations. On October 16, 2019, ECS collected a field blank and a groundwater sample from monitoring well MW-10 and water supply well WSW-25 (Figure 1) and submitted the samples for laboratory analysis of volatile organic compounds (VOCs) using EPA Method 6200B. Monitoring well MW-13 was located; however, could not be sampled due a large amount of standing surface water covering the monitoring well. Laboratory analysis detected several targeted analytes at concentrations above their respective North Carolina 2L Groundwater Quality Standards in the groundwater sample collected from monitoring well MW-10. Targeted analytes were not detected in the groundwater sample collected from water supply well WSW-25 or the field blank. Based on the results of this Letter Report, ECS concludes and recommends the following:  Based on historical reports for the site, a surficial release is associated with the active Handy House No. 10 gas station located across the street at 655 US 70, Davis, North Carolina. According to the historical reports provided to ECS by the NCDEQ there is no known source area on the subject site. Any reference to a release is associated with the Hand House No. 10 gas station. ECS recommends NCDEQ to provide ECS with any additional documentation regarding a known release at the Old Store site. If no known records are found, ECS recommends closing the site with a No Further Action (NFA).

limits. Wide recovery limits established for difficult compound. Wide RPD limits established for difficult compound. #Data exceeded client recommended or regulatory level Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the calculation which have not been rounded. No results have been blank subtracted unless specified in the case narrative section. FLAG/QUALIFIER SUMMARY Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated concentration (CLP J-Flag). J Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but the other is within limits. RPD between the two LFB/LCS results is within method specified criteria. L-07 Elevated reporting limit due to high concentration of target compounds.RL-11 [TOC_1]Flag/Qualifier Summary[TOC] Page 18 of 23 Table of Contents 39 Spruce Street * East Longmeadow, MA 01028 * FAX 413/525-6405 * TEL. 413/525-2332 CertificationsAnalyte CERTIFICATIONS Certified Analyses included in this Report SM21-22 6200B in Water NCAcetone NCBenzene NCBromobenzene NCBromochloromethane NCBromodichloromethane NCBromoform NCBromomethane NC2-Butanone (MEK) NCn-Butylbenzene NCsec-Butylbenzene NCtert-Butylbenzene NCCarbon Tetrachloride NCChlorobenzene NCChlorodibromomethane NCChloroethane NCChloroform NCChloromethane NC2-Chlorotoluene NC4-Chlorotoluene NC1,2-Dibromoethane (EDB) NC1,2-Dichlorobenzene NC1,3-Dichlorobenzene NC1,4-Dichlorobenzene NCDichlorodifluoromethane (Freon 12) NC1,1-Dichloroethane NC1,2-Dichloroethane NC1,1-Dichloroethylene NCcis-1,2-Dichloroethylene NCtrans-1,2-Dichloroethylene NC1,2-Dichloropropane NC1,3-Dichloropropane NC2,2-Dichloropropane NC1,1-Dichloropropene NCcis-1,3-Dichloropropene NCtrans-1,3-Dichloropropene NCDiisopropyl Ether (DIPE) NCEthylbenzene NC2-Hexanone (MBK) NCIsopropylbenzene (Cumene) NCp-Isopropyltoluene (p-Cymene) NCMethyl tert-Butyl Ether (MTBE) NCMethylene Chloride NC4-Methyl-2-pentanone (MIBK) NCNaphthalene NCn-Propylbenzene NCStyrene NC1,1,2,2-Tetrachloroethane [TOC_1]Certifications[TOC] Page 19 of 23 Table of Contents 39 Spruce Street * East Longmeadow, MA 01028 * FAX 413/525-6405 * TEL. 413/525-2332 CertificationsAnalyte CERTIFICATIONS Certified Analyses included in this Report SM21-22 6200B in Water NCTetrachloroethylene NCToluene NC1,2,3-Trichlorobenzene NC1,2,4-Trichlorobenzene NC1,1,1-Trichloroethane NC1,1,2-Trichloroethane NCTrichloroethylene NCTrichlorofluoromethane (Freon 11) NC1,2,3-Trichloropropane NC1,2,4-Trimethylbenzene NC1,3,5-Trimethylbenzene NCVinyl Acetate NCVinyl Chloride NCm+p Xylene NCo-Xylene The CON-TEST Environmental Laboratory operates under the following certifications and accreditations: Code Description Number Expires 100033AIHA-LAP, LLC - ISO17025:2017AIHA 03/1/2020 M-MA100Massachusetts DEPMA 06/30/2020 PH-0567Connecticut Department of Publilc HealthCT 09/30/2021 10899 NELAPNew York State Department of HealthNY 04/1/2020 2516 NELAPNew Hampshire Environmental LabNH-S 02/5/2020 LAO00112Rhode Island Department of HealthRI 12/30/2019 652North Carolina Div. of Water QualityNC 12/31/2019 MA007 NELAPNew Jersey DEPNJ 06/30/2020 E871027 NELAPFlorida Department of HealthFL 06/30/2020 LL015036Vermont Department of Health Lead LaboratoryVT 07/30/2020 2011028State of MaineME 06/9/2021 460217Commonwealth of VirginiaVA 12/14/2019 2557 NELAPNew Hampshire Environmental LabNH-P 09/6/2020 VT-255716Vermont Department of Health Drinking WaterVT-DW 06/12/2020 25703North Carolina Department of HealthNC-DW 07/31/2020 68-05812Commonwealth of Pennsylvania DEPPA 06/30/2020 Page 20 of 23 Table of Contents Page 21 of 23 Table of Contents Page 22 of 23 Table of Contents Page 23 of 23 Table of Contents
