The scope of services included the collection of a groundwater sample from monitoring wells MW-6 and MW-12. The scope of services was completed as proposed. Eight target compounds were detected in the sample collected from monitoring well MW-6 at concentrations greater than their respective 15A NCAC 2L .0202 Groundwater Quality Standards (2L Standards). Chloroform was detected in monitoring well MW-12 at a concentration greater than laboratory method detection limits but less than its respective 2L Standard. Field data sheets and the laboratory report are attached. The vault associated with monitoring well MW-12 is in poor condition and cannot be bolted down. It should be replaced by a North Carolina Licensed Well Driller to be in compliance with 15A NCAC 2C Section .0100 Well Construction Standards. If you have any questions or comments regarding this report, please contact us at your convenience. Sincerely, S&ME, Inc. Kelsey Vassallo David R. Loftis, P.E.

For method 6200B elevated reporting limit for samples 20B0864-01 due to high concentrations of target compounds. [TOC_1]Case Narrative[TOC] SM21-22 6200B Qualifications: Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits. Data validation is not affected since all results are "not detected" for associated samples in this batch and bias is on the high side. Analyte & Samples(s) Qualified: L-02 Vinyl Chloride B252791-BS1, B252791-BSD1 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. Analyte & Samples(s) Qualified: L-07 Ethanol B252791-BS1 Elevated reporting limit due to high concentration of target compounds. Analyte & Samples(s) Qualified: RL-11 20B0864-01[MW-6] The results of analyses reported only relate to samples submitted to the Con-Test Analytical Laboratory for testing. I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the best of my knowledge and belief, accurate and complete.

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 Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits. Data validation is not affected since all results are "not detected" for associated samples in this batch and bias is on the high side. L-02 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 15 of 20 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 NCEthanol 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 [TOC_1]Certifications[TOC] Page 16 of 20 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 NC1,1,2,2-Tetrachloroethane 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 03/1/2022 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 02/5/2021 LAO00112Rhode Island Department of HealthRI 12/30/2020 652North Carolina Div. of Water QualityNC 12/31/2020 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 12/14/2020 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 17 of 20 Table of Contents Page 18 of 20 Table of Contents Page 19 of 20 Table of Contents Page 20 of 20 Table of Contents
