Two underground storage tanks (USTs) were historically operated at the site. Two 500-gallon gasoline USTs were removed from the site on April 26, 1991. A third orphan UST is referenced as having been encountered during excavation activities and subsequently removed, but no further information about this UST is available. A petroleum release was discovered during tank closure activities. The purpose of this report is to document the latest groundwater sampling event. On April 6, 2023, CATLIN Engineers and Scientists (CATLIN) personnel measured groundwater in the shallow Type II wells (MW-1, MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-13, MW-16, and MW-17) at an average depth of 3.34 feet below top of casing (BTOC). Depth to water was measured in the deep Type III wells (DW-2, DW-3, DW-4, and DW-6) was an average of 10.6 feet BTOC. Groundwater samples were collected from a total of 14 groundwater monitoring wells (MW-1, MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-13, MW-16, MW- 17, DW-2, DW-3, DW-4, and DW-6) and three water supply wells (WSW-6151, WSW-6152, and WSW-6160). The samples were submitted for laboratory analysis of volatile organic compounds (VOCs) per Standard Method (SM) 6200B plus ethylene dibromide (EDB), methyl tert-butyl ether (MTBE), and diisopropyl ether (DIPE). Laboratory results did not indicate any dissolved petroleum constituents above their respective laboratory reporting limits in the samples from MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-16, MW-17, and DW-6. One or more VOCs were detected in the MW-1, MW-13, DW-2, and DW-3 samples at concentrations greater than those established in Title 15A of the North Carolina Administrative Code, Subchapter 2L, Section .0202 Groundwater Quality Standards (2L GWQS), but below the Gross Contaminant Levels (GCL). Analysis of the sample from water supply well WSW-6152 revealed 1,2- dichloroethane at a concentration above 2L GWQS. The following VOCs were also detected above their reporting limits, but below 2L GWQS, in the WSW-6152 sample: benzene, DIPE, and MTBE. No targeted analytes were reported in the WSW-6151 and WSW-6160 samples. The groundwater samples collected during this event from shallow monitoring wells MW-1, MW-4, and MW-13 revealed contaminant concentrations generally lower than those detected during the August 2021 sampling event, while those in deep monitoring well DW-3 have fluctuated. Water supply well WSW-6152 continues to be impacted with 1,2-dichloroethane. CATLIN recommends to: • Determine the feasibility of relocating WSW-6152; • Evaluate in-situ remedial options to reduce groundwater contamination; and • Conduct a semi-annual sampling event in October 2023. NCDEQ; 6532_Country Corner Grocery CATLIN Engineers and Scientists CATLIN Project No. 221047 3 May 2023 3.0 SCOPE OF SERVICES The scope of services for this report was performed in general accordance with CATLIN proposal number 221047.02P, dated March 14, 2023. Services were authorized by the North Carolina Department of Environmental Quality’s (NCDEQ’s) Task Authorization (TA) #02, accepted on March 15, 2023, and Contract Number N122019D. The approved scope of services for this Task Authorization included: • Collect groundwater samples from 14 monitoring wells (MW-1, MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-15, MW-16, MW-17, DW-2, DW-3, DW-4, and DW-6); • Collect groundwater samples from three water supply wells (WSW-6160, WSW-6152, and WSW-6151); • Analyze 19 water samples (14 monitoring well samples, three water supply well samples, one equipment rinsate blank, and one trip blank) via SM 6200B (including EDB, MTBE, and DIPE); • Attempt to locate monitoring well DW-2; and, • Prepare and submit a monitoring report summarizing the findings. The scope of services was conducted in general accordance with the approved TA. 4.0 SITE HISTORY AND CHARACTERIZATION The Country Corner Grocery site is located at 6122 Sharpe Store Road, Elm City, Wilson County, North Carolina (Figures 1 and 2). Summarized available historical gauging and sampling data from previous consultants are provided in Appendix A. Site photographs are presented in Appendix B. 4.1 UST OWNER AND OPERATOR INFORMATION Sharpe Oil Company owned the two USTs historically operated on-site. A former country store, Country Corner Grocery, operated the tanks for retail petroleum sales. A third orphan UST is referenced in the Corrective Action Plan (CAP) submitted by UTTS Environmental (UTTS) March 1993, but no further information is available. Country Corner Grocery was closed/ abandoned on December 27, 1984, and the site was subsequently accepted into the North Carolina UST Section Trust Fund Branch State Lead Program (UTTS, 1993). Available information regarding UST owners/operators and is presented on Table 1. 4.2 UST INFORMATION Two 500-gallon gasoline USTs operated at the site and were reportedly installed in the 1950s and removed from the site in April 1991. A third orphan UST was reportedly encountered and removed during the UST closures, but NCDEQ; 6532_Country Corner Grocery CATLIN Engineers and Scientists CATLIN Project No. 221047 4 May 2023 no additional information on this tank is available. The exact installation and operation dates of the 500-gallon tanks and the orphan UST are uncertain (UTTS, 1991). Available UST system information is presented in Table 1 and the approximate former UST locations are illustrated on Figure 3. 4.3 CONTAMINANT SOURCE INVENTORY An on-site release was discovered in 1991 during UST removal activities. Several holes were reportedly noted in one of the USTs at the time of removal, and the laboratory analytical results of confirmatory soil samples indicated that total petroleum hydrocarbons (TPH) were reported at concentrations above the State Action Level (S&ME, 2020). Upon installation and sampling of groundwater monitoring wells and sampling of the adjacent water supply wells, the analytical laboratory results indicated that petroleum constituents were detected in concentrations that exceeded the 2L GWQS (UTTS, 1991). 4.4 SITE CHARACTERISTICS The property is owned by Christopher Lawrence Ballard and Emily Lynn Ballard Pate. The former store structure has been razed. The parcel is comprised of agricultural and wooded land. 4.5 OWNERS AND OCCUPANTS OF ADJOINING/NEARBY PROPERTIES AND LAND USE Properties in the site vicinity are mostly residences and agricultural land. Residents are located across Stagecoach Road to the north and west. To the northwest and the northeast across Stagecoach Road are wooded and agricultural land, respectively. Agricultural land is present to the east and the south of the site. 4.6 RECEPTOR INFORMATION Conducting a receptor survey was outside the scope of this monitoring event. However, based on available information, there are nine potable water supply wells located within 1,000 feet of the site, and four of these wells are located within 500 feet of the source area. According to previous reports, municipal water is not available to the site or surrounding properties (S&ME, 2020). Historically, the groundwater flow in the surficial aquifer has been towards the northeast and the groundwater flow in the deeper aquifer (north of Stagecoach Road was to the southeast. Based on these flow directions and proximity to the site, it is likely that the only water supply wells that may be at risk are WSW-6152, WSW-6151, WSW-6160, WSW-6145, and WSW-6158. NCDEQ; 6532_Country Corner Grocery CATLIN Engineers and Scientists CATLIN Project No. 221047 5 May 2023 An unnamed pond located approximately 1,150 feet to the south-southwest. Potential receptors are illustrated on Figure 2 and receptor information is shown on Table 2. 4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES Historical files available on Laserfiche do not fully elucidate the site history. A summary of on-site investigations and remedial activities indicated in previous reports is provided herein. The release was discovered in 1991 during UST closure activities. Following UST removal, holes were observed in one of the 500-gallon USTs. A third orphan UST was reportedly discovered and removed, but further information on this tank is not available. A sheen was observed on the groundwater that seeped into the excavation. Reportedly, approximately 460 cubic yards of petroleum-impacted soil was excavated at the time of the UST removals. Confirmation soil samples collected from the base of the excavation contained TPH at concentrations which exceeded the North Carolina State Action Levels (UTTS, 1993). In October 1991, a Comprehensive Site Assessment (CSA) was submitted by UTTS documenting site activities. In July 1991, three Type II groundwater monitoring wells (MW-1 through MW-3) were installed by UTTS, and in August 1991 UTTS installed Type II wells MW-4 through MW-8 and Type III monitoring well DW-1. In September 1991, UTTS installed Type II monitoring wells MW-9 through MW-14. Laboratory analytical results from the groundwater samples collected periodically from the wells showed petroleum constituents at concentrations which exceeded their 2L GWQS. Additionally, a slug test was performed on monitoring wells MW-3 and MW-9. Based on the slug test data, the average hydraulic conductivity was calculated to be 0.47 feet per day (ft/d) and the average calculated groundwater velocity was 0.13 ft/d. Groundwater flow direction was determined to be toward the northeast (UTTS, 1991). A CAP was prepared to evaluate the available remedial alternatives for reduction of the groundwater contamination by UTTS in January 1992 and submitted to the North Carolina Department of Environment and Natural Resources (NCDENR, now NCDEQ) Raleigh Regional Office (RRO) for review. An evaluation of the remedial alternatives yielded a recommendation for pump-and-treat technology. The RRO requested that three additional Type II wells (MW-15 through MW-17) and one Type III well (DW-2) be installed. The laboratory results from the sample from DW-2 indicated the presence of petroleum constituents at concentrations which exceeded their 2L GWQS (ECE, 1998). NCDEQ; 6532_Country Corner Grocery CATLIN Engineers and Scientists CATLIN Project No. 221047 6 May 2023 Additional work was required by the RRO and a Revised CAP was submitted by UTTS in April 1993. This plan included the originally proposed system as well as additional groundwater recovery wells (ECE, 1998). The RRO issued a Notice of Violation (NOV) to Sharpe Oil Company, re-ranked the site as a high-risk classification, and requested additional activities. Sharpe Oil Company requested that East Coast Environmental, P.A. (ECE) complete the additional site activities. Additional Type III wells DW-3 through DW-6 were installed to characterize the confined aquifer. A groundwater monitoring event was conducted by S&ME, Inc. (S&ME) in July 2020 in conjunction with surveying the top of casing elevations of the groundwater monitoring wells. Petroleum constituents were reported above their 2L GWQS in samples from MW-1, MW-4, MW-13, DW-2, DW-3, and DW-4 (S&ME, 2020). CATLIN conducted a groundwater monitoring event in August 2021. Thirteen accessible monitoring wells and three water supply wells (WSW-6151, WSW- 6152, and WSW-6160) were sampled. For the Type II wells, laboratory analysis revealed multiple petroleum constituents above 2L GWQS in the sample from MW-1 as well as benzene above 2L GWQS in the MW-4 and MW-13 samples. Among the Type III wells, only DW-3 had 2L GWQS exceedances (1,2-dichloroethane and MTBE). No contaminants were above GCL. The sample from water supply well WSW-6152 contained 1,2- dichloroethane above 2L GWQS; a resampling revealed similar concentrations (CATLIN, 2021). Summarized available historical gauging and sampling data from previous consultants are presented in Appendix A. 5.0 REGIONAL AND SITE GEOLOGY AND HYDROGEOLOGY 5.1 SOIL AND BEDROCK As defined in the Geologic Map of North Carolina, published by the North Carolina Department of Natural Resources and Community Development (1985), the site lies within the Coastal Plain physiographic province. The North Carolina Coastal Plain is approximately 90 to 150 miles wide from the Atlantic Ocean westward to its boundary with the Piedmont province. Two natural subdivisions of the Coastal Plain were described by Stuckey (1965): the Tidewater region and the Inner Coastal Plain. The project area is located within the Inner Coastal Plain, which is an area of erosional topography (Horton and Zullo, 1991). The Coastal Plain comprises a wedge-shaped sequence of stratified marine and non-marine sedimentary rocks deposited on crystalline basement. The NCDEQ; 6532_Country Corner Grocery CATLIN Engineers and Scientists CATLIN Project No. 221047 7 May 2023 sedimentary sequences range in age from Recent to lower Cretaceous (Narkunas, 1980). According to the 1985 North Carolina Geologic Survey Geological Map of North Carolina, the site is underlain by the Tertiary Yorktown formation, which consists of clay and sand. According to the US Department of Agriculture Web Soil Survey the site soils consist of the Norfolk fine sandy loam, a well-drained soil with 0-2 percent slopes. The soils of the Norfolk sandy loam consist of sand, sandy loam, and sandy clay loam. According to boring logs provided in the ECE CSA Addendum, the soils encountered at the site included sand, silty sand, clayey sand, and sandy clay. 5.2 HYDROGEOLOGY Groundwater - The 2020 Visual Hydrogeologic Framework – North Carolina Hydrogeological Database did not identify boreholes near the site. Surface Water – There is one surface water body within 1,500 feet of the site; an unnamed pond is located approximately 1,150 feet to the south-southwest. 6.0 SITE ASSESSMENT INFORMATION CATLIN conducted field activities on April 6, 2023 in accordance with the approved TA and pre-prepared Health and Safety Plan (HASP). Upon arrival at the site, potential hazards were evaluated before beginning field work and are documented on an electronic Job Hazard Analysis (JHA) form. The JHA form is included in Appendix C. Photographs from the site visit are included in Appendix B. CATLIN personnel gauged and collected groundwater samples for laboratory analysis of VOCs per SM 6200B from 14 monitoring wells (MW-1, MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-13, MW-16, MW-17, DW-2, DW-3, DW-4, and DW-6). Additionally, samples were collected from three water supply wells (WSW-6151, WSW-6152, and WSW-6160). Water supply well locations are illustrated on Figure 2 and available property information is presented on Table 2. Monitoring well locations and site features are shown on Figure 3 and well construction details are presented on Table 3. 6.1 GAUGING DATA Historically, depth to water in the Type II wells has ranged from 0.76 feet BTOC (MW-4) to 12.58 feet BTOC (MW-12). Depth to water in the Type III wells has varied from 7.68 feet BTOC (DW-6) to 18.52 feet BTOC (DW-3). Groundwater flow has historically been toward the north-northeast (S&ME, 2020; CATLIN, 2021). NCDEQ; 6532_Country Corner Grocery CATLIN Engineers and Scientists CATLIN Project No. 221047 8 May 2023 During the April 2023 event, CATLIN personnel measured depth to water using an electronic water level probe. To prevent cross contamination, the probe and cabling were decontaminated according to the manufacturer’s recommendations between use in each well. Gauging data were recorded on an electronic groundwater sampling form using a tablet device. Gauging procedures were performed in general accordance with NCDENR and NCDEQ Guidelines and Environmental Protection Agency (EPA) Region 4 Operating Procedures. Depth to water was measured in the shallow Type II wells (MW-1, MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-13, MW-16, and MW-17) ranging from 1.34 feet BTOC (MW-4) to 5.61 feet BTOC (MW-7). Depth to water was measured in the deep Type III wells (DW-2, DW-3, DW-4, and DW-6) ranging from 9.34 feet BTOC (DW-6) to 11.87 feet BTOC (DW-2). The water levels in each of the wells gauged was measured above its respective screened interval. The topography surrounding the site is flat and based on groundwater elevations calculated for this monitoring period, groundwater flow direction appears to be generally northeast. Monitoring well gauging results for events conducted by CATLIN are presented in Table 3. Groundwater elevation is illustrated on Figure 4 and groundwater sampling forms are provided in Appendix C. 6.2 SAMPLING DATA Following gauging, the monitoring wells and water supply wells were sampled in general accordance with NCDEQ Guidelines and U.S. EPA Region 4 Operating Procedures. Prior to obtaining representative groundwater samples, each monitoring well was purged by removing a minimum of three well volumes (or the well was purged dry) using a new, disposable bailer. The water supply wells were purged by allowing the spigot to run for approximately 15 minutes. Groundwater field parameter data were measured at one-minute intervals using an In-Situ Aqua TROLL 600 Multiparameter Sonde (Aqua TROLL). The Aqua TROLL measured specific conductivity, pH, oxidation reduction-potential (ORP), dissolved oxygen, and temperature, which were recorded utilizing the VuSitu mobile application (version 1.17.12). Groundwater parameter data were transferred from the VuSitu mobile application to the electronic groundwater sampling forms. Copies of the groundwater sampling forms are available in Appendix C. After purging activities, a groundwater sample was collected from each well and poured directly into appropriate, laboratory-provided, pre-preserved glassware, labeled, and placed on ice in an insulated cooler. An equipment rinsate blank was collected by pouring water from a new, sealed gallon of distilled water across the electronic water level probe and collected directly into laboratory-provided glassware. The glassware was NCDEQ; 6532_Country Corner Grocery CATLIN Engineers and Scientists CATLIN Project No. 221047 9 May 2023 labeled and placed on ice in an insulated cooler. A laboratory-provided trip blank was maintained in the cooler for the duration of the sampling event. The groundwater samples, equipment rinsate blank, and laboratory-provided trip blank were submitted to Con-Test Analytical Laboratory (Certification NC 652 and NC-DW 25703) in East Longmeadow, Massachusetts, under proper chain of custody (COC) protocol and analyzed per SM 6200B (including EDB, MTBE, and DIPE). The laboratory analytical data and COC are included in Appendix D. 6.3 SUMMARY OF GROUNDWATER INFORMATION Historically, the samples from monitoring well MW-1 have contained the highest petroleum constituent concentrations. Light non-aqueous phase liquid (LNAPL, aka free product) has not been measured at this site. Historical groundwater sampling and gauging data from previous consultants are provided in Appendix A. During the previous sampling event conducted by CATLIN (August 2021), Type II well samples from MW-1 contained multiple VOCs at concentrations above 2L GWQS, and MW-4 and MW-13 contained benzene concentrations above 2L GWQS. The sample from Type III well DW-3 contained 1,2-dichloroethane and MTBE at concentrations which exceeded 2L GWQS. No petroleum constituents have been detected at concentrations above GCL. The laboratory analytical results from water supply well WSW-6152 have historically revealed increasing levels of 1,2-dichloroethane. The latest groundwater sampling laboratory results for SM 6200B analysis are summarized in Table 4. Historical results for events conducted by CATLIN are in Table 5. Type II and Type III monitoring well sample analytical results are illustrated on Figures 5 and 6, respectively. Water supply well groundwater sample analytical results are illustrated on Figure 7. A copy of the complete laboratory report and COC documentation are in Appendix D. Monitoring Wells During the April 2023 monitoring event, 14 monitoring well groundwater samples (MW-1, MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-13, MW-16, MW-17, DW-2, DW-3, DW-4, and DW-6) were collected and submitted for analysis via SM 6200B (including EDB, MTBE, and DIPE). Laboratory analysis did not detect any constituents above the reporting limits in the samples from wells MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-16, MW-17, and DW-6. A low concentration of MTBE was reported in the DW-4 sample, but it was below 2L GWQS. No analyte concentrations were detected above GCL in any of the monitoring well samples. Analytical results reported the following constituents at concentrations above their 2L GWQS in samples MW-1, MW-13, DW-2, and DW-3: NCDEQ; 6532_Country Corner Grocery CATLIN Engineers and Scientists CATLIN Project No. 221047 10 May 2023 • MW-1: benzene and naphthalene; • MW-13: benzene; • DW-2: benzene, 1,2-dichloroethane, and MTBE; and • DW-3: 1,2-dichloroethane. Water Supply Wells Groundwater samples were obtained from three water supply wells (WSW-6151, WSW-6152, and WSW-6160). Laboratory analysis did not detect any constituents above their respective 2L GWQS in the samples from WSW-6151 or WSW-6160. The laboratory results from the sample from water supply well WSW-6152 revealed 1,2-dichloroethane at a concentration which exceeded its 2L GWQS. Additionally, benzene, diisopropyl ether, and MTBE were detected at concentrations which exceeded their respective method detection limits. A low concentration of MTBE was reported in the WSW-6160 sample, but it was well below 2L GWQS. Equipment Rinsate Blank and Trip Blank One equipment rinsate blank sample and one laboratory-provided trip blank sample were submitted for analysis per SM 6200B (including EDB, MTBE, and DIPE). An estimated (“J”-value) concentration of acetone (a common laboratory relic) was detected in the equipment rinsate blank sample. No targeted analytes were detected in the trip blank sample. 6.4 EVALUATION OF ASSESSMENT INFORMATION Extent of Contamination One or more petroleum constituents were detected above their respective 2L GWQS in the samples from MW-1, MW-13, DW-2, and DW-3. LNAPL was not detected in any of the wells. The latest groundwater sampling laboratory results for SM 6200B analysis are summarized in Table 4. Type II and Type III monitoring well sample analytical results are illustrated on Figures 5 and 6, respectively, and the water supply well groundwater sample analytical results are illustrated on Figure 7. The highest contaminant concentrations have historically been reported in samples from MW-1. The groundwater samples collected during this event from monitoring wells MW-1, MW-4, and MW-13 revealed contaminant concentrations generally lower than those detected during the August 2021 sampling event and the contaminant concentrations in DW-3 have fluctuated. Water supply well WSW-6152 continues to be impacted by 1,2-dichloroethane at concentrations which exceed the 2L GWQS. NCDEQ; 6532_Country Corner Grocery CATLIN Engineers and Scientists CATLIN Project No. 221047 11 May 2023 Cleanup Levels Achieved Soil – In April 1991, approximately 460 cubic yards of petroleum-impacted soil was excavated at the time of the UST removals. Confirmation soil samples collected from the base of the excavation contained TPH at concentrations which exceeded the State Action Levels (UTTS, 1991). Groundwater – Groundwater contaminant concentrations are above 2L GWQS, but below GCL at the site. The laboratory analytical results from water supply well sample from WSW-6152 revealed 1,2-dichloroethane at a concentration which exceeded the 2L GWQS. LNAPL – LNAPL has not been observed at the site. 7.0 CONCLUSIONS AND RECOMMENDATIONS Conclusions Groundwater monitoring findings for this period are summarized below: • Fourteen monitoring wells (MW-1, MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-13, MW-16, MW-17, DW-2, DW-3, DW-4, and DW-6) and three water supply wells (WSW-6151, WSW-6152, and WSW-6160) were sampled. • No analyzed compound concentrations were detected above the reporting limits in the samples from Type II monitoring wells MW-4, MW-5, MW-6, MW-7, MW-11, MW-12, MW-16, or MW-17. • No analyzed compound concentrations were detected above the 2L GWQS in the samples from Type III wells DW-4 or DW-6. • One or more petroleum constituents above their 2L GWQS were reported in the Type II wells MW-1, MW-4, and MW-13 and Type III wells DW-2 and DW-3. • WSW-6152 continues to be impacted with the petroleum constituent 1,2-dichloroethane at a concentration above its 2L GWQS. • The groundwater samples collected during this event from Type II wells MW-1, MW-4, and MW-13 revealed contaminant concentrations generally lower than those detected during the August 2021 sampling event, while those in Type III well DW-3 have fluctuated. • Groundwater flow appears to be generally northeast. Recommendations CATLIN recommends to: • Determine the feasibility of relocating WSW-6152; • Evaluate in-situ remedial options to reduce groundwater contamination; and • Conduct a semi-annual sampling event in October 2023.

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. RL Reporting Limit is at the level of quantitation (LOQ) DL Detection Limit is the lower limit of detection determined by the MDL study MCL Maximum Contaminant Level ND Not Detected 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 Elevated reporting limit due to high concentration of target compounds.RL-11 [TOC_1]Flag/Qualifier Summary[TOC] Page 49 of 55 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 SM21-23 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 50 of 55 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 SM21-23 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 Con-Test, a Pace Environmental Laboratory, operates under the following certifications and accreditations: Code Description Number Expires 652North Carolina Div. of Water QualityNC 12/31/2023 Page 51 of 55 Table of Contents Page 52 of 55 Table of Contents Page 53 of 55 Table of Contents Page 54 of 55 Table of Contents Page 55 of 55 Table of Contents
