Vacant store building Groundwater Monitoring Report – Former Middleburg Grocery Property NCDEQ Incident No. TF-6174 UST No. RA-918 ECS Project No. 49:1638-E On February 18, 2020, ECS collected a field blank and groundwater samples from monitoring wells MW- 1R, MW-2R, MW-4R, MW-6, MW-12, MW-13, and DW-1. Monitoring wells MW-5 and MW-11R were both measured dry and therefore, groundwater samples could not be collected. Additionally, ECS collected groundwater samples from water supply wells WSW-1, WSW-2, and WSW-13. Laboratory analysis reported several targeted analytes at concentrations above their respective North Carolina 2L Groundwater Quality Standard (NC2LGWQS) but below their respective Gross Contamination Levels (GCLs) in the groundwater samples collected from monitoring wells MW-1R, MW-4R, and MW-12. Laboratory analysis reported several additional targeted analytes above their respective laboratory reporting limits but below their respective NC2LGWQS in the groundwater samples collected from monitoring wells MW-1R, MW-4R, and MW-12. Based on the results of this assessment, ECS concludes the following: • Since the previous O-Sox deployment on June 16, 2019, benzene and ethylene dibromide (EDB) concentrations have decreased by 76.9 and 74.7 percent (%), respectively, in the groundwater samples collected from monitoring well MW-1R. Successfully reducing EDB below its GCL. • Laboratory analysis detected chloroform at a concentration above the laboratory detection limit but below its NC2LGWQS in the groundwater sample collected from water supply well WSW-1. The chloroform detection was denoted with a J-Flag which indicates the compound was detected but below the reporting limit; therefore, it is an estimated concentration. It is ECS’s opinion that the result is due to a laboratory contaminant and not a contaminant of the site. • Based on groundwater elevation data, groundwater flows towards the east – southeast away from the closest active water supply well WSW-1. • Previous predictive computer modeling using conservative input values indicated the existing plume of petroleum-related compounds is not expected to be present above laboratory reporting limits or applicable NC2LGWQS no more than 600 feet from the ‘source area’ (monitoring well MW-1R) over a period of 100 years. Therefore, the model demonstrated water supply well WSW-16, located approximately 700 feet downgradient and southeast of the site, is not expected to be impacted by this release. Based on the results and conclusions of this assessment, ECS recommends conducting two additional groundwater monitoring events for a total of three consecutive groundwater monitoring events to determine if concentrations remain below the GCLs along with continual redeployment of new O-SOX remedial devices in monitoring wells MW-1R and MW-12. If concentrations continue to remain below the GCLs after the after three consecutive groundwater monitoring events, ECS recommends the NCDEQ consider issuing a Notice of Residual Petroleum (NRP) for soil and groundwater contamination and the NCDEQ should consider issuing a letter of No Further Action (NFA). Additionally, if a NFA is issued ECS recommends abandoning the monitoring wells associated with the site.

According to information provided to ECS by the North Carolina Department of Environmental Quality (NCDEQ), three 1,000-gallon and two 550-gallon underground storage tanks (USTs) containing gasoline were removed from the site in April 1991. Additionally a 280-gallon kerosene UST was removed in June 2004 (Table 1). Laboratory analysis of soil samples collected from the UST basins following UST removal identified petroleum-related contamination originating from four of the five USTs. In December 1990, the NCDEQ identified the Middleburg Grocery Site and the Middleburg Variety as potential sources of petroleum contamination due to the operation of USTs and aboveground storage tanks (ASTs) at each of the sites. The Middleburg Variety is located approximately 290 feet northeast of the subject site. In May 1992, Environmental Aspects, Inc. (EAI) removed one 6,000-gallon gasoline UST, one 1,000-gallon kerosene UST, and one 1,000-gallon diesel UST from the Middleburg Variety. Additionally, EAI removed approximately 20 cubic yards of soil from the vicinity of the kerosene UST. In August 1992, EAI removed 280 cubic yards of soil from the vicinity of the dispenser island and product lines at the Middleburg Variety. In July 1992, Geophex, Ltd. conducted a magnetic and ground penetrating radar (GPR) survey at the subject site and the former Fogg Property, which is located adjacent to the subject site, across North Hawkins Avenue. The survey identified two anomalies on the Fogg Property. The anomalies included one UST on the northern portion of the Fogg Property and one septic tank. In May 1994, ATEC Associates, Inc. (ATEC) observed stockpiled soils on the Fogg Property. The soil was stockpiled on black plastic in the center of the property. ATEC also observed one kerosene AST at the Middleburg Variety Store. In 1994, a water supply well sampling event was conducted. Ten water supply wells were sampled and targeted analytes were reported in six of the ten wells. In 1996, a study was conducted to determine the feasibility to connect one of the residences with an impacted water supply well to the municipal water supply. ECS is not aware of the outcome of this study. In May and June 2001, a soil and groundwater assessment was conducted. Twelve (12) soil borings were advanced to a depth of approximately 20 feet below the ground surface (ft bgs) in the vicinity of the former USTs. From the twelve borings, six (6) soil samples and three groundwater samples were collected. Laboratory analysis of three of the 6 soil samples and each of the groundwater samples reported targeted analytes at concentrations above their respective laboratory reporting limits. In July 2003, a receptor survey was completed. The receptor survey identified twenty-four (24) water supply wells within 1,500 feet of the site. Nine (9) of the twenty four (24) water supply wells were subsequently sampled. Analytical results from four of the water supply wells identified petroleum-related impact. Also at that time, ten soil borings were advanced on the site and adjacent properties. Soil borings SB-1, SB-3, SB-7, SB-9, and SB-10 were converted into groundwater monitoring wells (MW-1 through MW- 5) and subsequently sampled. Laboratory analysis of three (3) of the five (5) groundwater monitoring wells reported targeted analytes at concentrations above their respective laboratory reporting limits. The highest concentration of groundwater impacts was noted in monitoring well MW-1. Groundwater Monitoring Report – Former Middleburg Grocery Property NCDEQ Incident No. TF-6174 UST No. RA-918 ECS Project No. 49:1638-E 2 In June 2004, contaminated soil was excavated from the vicinity of the former tank pit. During excavation activities, an approximate 280-gallon kerosene UST was encountered and subsequently removed. Approximately 393 tons of soil was excavated and disposed. Laboratory analysis of closure soil samples collected from the vicinity of the kerosene UST reported total petroleum hydrocarbons-diesel range organics (TPH-DRO) at concentrations above the NCDEQ UST Section’s Action Level. In August 2004, soil borings were advanced on adjacent properties. Four (4) of the six (6) borings were converted into monitoring wells (MW-6 through MW-9) and were subsequently sampled along with site monitoring wells MW-1 through MW-5. Laboratory analysis of the groundwater samples collected from monitoring wells MW-1, MW-5, and MW-7 reported targeted analytes at concentrations above their respective NC2LGWQS with the highest concentrations reported in monitoring well MW-1. In September 2006, monitoring wells MW-1R, MW-2R, MW-4R, and MW-7R were installed to replace monitoring wells MW-1, MW-2, MW-4, and MW-7 which were dry during the May 2006 sampling event. Upon installation, a groundwater monitoring event was conducted at the site. Laboratory analysis of the groundwater samples collected from monitoring wells MW-1R, MW-4R, MW-5, and MW-7R reported targeted analytes at concentrations above their respective NC2LGWQS. Laboratory analysis of groundwater samples collected from water supply wells sampled during this sampling event did not report targeted analytes at concentrations above their respective laboratory reporting limits. In July 2009, Terraquest conducted a groundwater monitoring event of monitoring wells MW-1R, MW-2R, MW-4R through MW-7R, and from water supply wells WSW-1, WSW-2, WSW-4, WSW-5, WSW-6, WSW-8, WSW-10, and WSW-11. Laboratory analysis of the groundwater samples collected from monitoring wells MW-1R, MW-4R, MW-5, and MW-7R reported targeted analytes at concentrations above their respective NC2LGWQS with benzene reported above its GCL in groundwater collected from monitoring well MW-1R. Laboratory analysis of the water supply well samples did not report targeted analytes at concentrations above their respective laboratory reporting limits. In December 2009, Terraquest conducted a mobile multi-phase extraction event (MMPE) on the site using monitoring well MW-1R as an extraction point. In March 2010, monitoring wells MW-10 through MW-13 were installed and the monitoring well network was sampled. Free product at a thickness of 0.02 inches was discovered in monitoring wells MW-1R and MW-4R. Laboratory analysis of the groundwater samples collected from monitoring wells MW-5R, MW-7R, and MW-12 reported targeted analytes at concentrations above their respective NC2LGWQS. In February 2013, Terraquest conducted a monitoring well sampling event of the monitoring well network. Free product was discovered in monitoring wells MW-1R and MW-2R and monitoring wells MW-5 and MW-11 were dry. Laboratory analysis of the groundwater samples collected from monitoring wells MW- 4R, MW-7R, MW-14, and DW-1 reported targeted analytes at concentrations above their respective NC2LGWQS. Terraquest recommended that an MMPE event be conducted to remove free product from monitoring wells MW-1R and MW-2R, to install a Type II monitoring well on the off-site property across North Lee Street from the site to further delineate the contaminant plume, to connect properties containing water supply wells WSW-1, WSW-2, WSW-4, WSW-5, and WSW-13 to the municipal water supply, and to continue groundwater sampling of the monitoring well network. Groundwater Monitoring Report – Former Middleburg Grocery Property NCDEQ Incident No. TF-6174 UST No. RA-918 ECS Project No. 49:1638-E 3 On October 17, 2014, ECS collected twelve (12) groundwater samples from monitoring wells MW-1R, MW-2R, MW-4R, MW-5, MW-6, MW-7R, MW-11 through MW-15, and DW-1 and one groundwater sample from water supply well WSW-13. Laboratory analysis of the groundwater samples collected from monitoring wells MW-1R and MW-12 reported 1,2-dibromoethane (EDB) at a concentration above its NC2LGWQS and its GCL. On May 1, 2015, ECS contracted CCI to conduct an aggressive fluid and vapor recovery (AFVR) event on monitoring wells MW-1R and MW-12. The AFVR activities lasted eight hours and were performed in general accordance with the Guidelines. Prior to the AFVR event, free product was not observed in monitoring wells MW-1R and MW-12. CCI connected the AFVR recovery pump to monitoring wells MW- 1R and MW-12 and ran the vacuum from 9:00 AM on May 1, 2015 through 5:00 PM on May 1, 2015 (approximately 8 hours). A total of 600 gallons of water was removed from the monitoring wells. ECS recorded readings and tracked the progress of the AFVR event. Depth to groundwater readings from monitoring wells MW-2, DW-1, MW-11, and MW-13 were recorded. On May 15, 2015, ECS collected eleven (11) groundwater samples from site monitoring wells and collected a groundwater sample from water supply well WSW-13. In addition, ECS contracted with Bateman Civil Survey to survey the site monitoring wells. Laboratory analysis reported EDB at a concentration above its NC2LGWQS and its GCL in the groundwater sample collected from monitoring well MW-12. On March 10, 2016, ECS collected ten (10) groundwater samples from monitoring wells MW-1R, MW- 2R, MW-4R, MW-5, MW-6, MW-11 through MW-14, and DW-1, and a groundwater sample from water supply well WSW-13. ECS installed O-SOX in monitoring wells MW-1R, MW-4R, MW-5, MW-11, and MW-12. Laboratory analysis reported EDB at a concentration above its NC2LGWQS and its GCL in the groundwater sample collected from monitoring well MW-12. On June 14, 2017, ECS collected a field blank and groundwater samples from monitoring wells MW-1R, MW-4R, MW-5, MW-11, MW-12, and DW-1. ECS removed O-SOX from monitoring wells MW-1R, MW- 4R, MW-5, MW-11, and MW-12 and installed new O-SOX in monitoring well MW-1R, MW-4R, MW-5, and MW-12. Laboratory analysis reported EDB at a concentration above its NC2LGWQS and its GCL in the sample collected from monitoring well MW-1R. On June 26, 2018, ECS collected a field blank and groundwater samples from monitoring wells MW-1R, MW-2R, MW-4R, MW-5, MW-6, MW-12, MW-13, and DW-1 and from water supply wells WSW-1, WSW-2, and WSW-13. ECS removed O-SOX from monitoring wells MW-1R, MW-4R, MW-5, and MW-12 and installed new O-SOX in monitoring well MW-1R, MW-4R, MW-5, and MW-12. Laboratory analysis reported EDB at a concentration above its NC2LGWQS and its GCL in the sample collected from monitoring well MW-1R. On July 16, 2018, ECS contracted with Quantex to advance six (6) soil borings to characterize the horizontal and vertical extent of possible soil contamination near monitoring wells MW-1R and MW-12. Laboratory analysis reported several targeted analytes at concentrations above their respective Soil-to- Water Maximum Soil Contaminant Concentrations (MSCCs) but below their respective residential MSCCs (Table 2) in soil samples SS-1-15, SS-2-15, SS-3-15, SS-5-10, and SS-5-15 (Figure 3). Groundwater Monitoring Report – Former Middleburg Grocery Property NCDEQ Incident No. TF-6174 UST No. RA-918 ECS Project No. 49:1638-E 4 On February 14, 2019, ECS contracted with Zebra Environmental & Industrial Services (Zebra) to conduct an AFVR event at the site using monitoring wells MW-1R and MW-12 as extraction points. On February 22, 2019, Quantex, on behalf of ECS, installed one (1) Type II groundwater monitoring well MW-11R. On February 27 and 28, 2019, ECS collected a field blank and groundwater samples from monitoring wells MW-1R, MW-2R, MW-4R, MW-6, MW-11R, MW-12, MW-13, and DW-1. Additionally, ECS collected groundwater samples from water supply wells WSW-1, WSW-2, and WSW-13. Laboratory analysis reported benzene and EDB at a concentration above their respective NC2LGWQS and their respective GCLs in the groundwater samples collected from monitoring well MW-1R. Laboratory analysis reported several targeted analytes at concentrations above their respective NC2LGWQS but below their respective GCLs in the groundwater samples collected from monitoring wells MW-1R, MW-4R, MW-11R, and MW-12. On July 16, 2019, ECS collected a field blank and groundwater samples from monitoring wells MW-1R, MW-2R, MW-4R, MW-6, MW-12, MW-13, and DW-1 and from water supply wells WSW-1, WSW-2, and WSW-13. Laboratory analysis reported EDB at a concentration above its NC2LGWQS, and its GCL in the groundwater sample collected from monitoring well MW-1R. Laboratory analysis reported several targeted analytes at concentrations above their respective NC2LGWQS but below their respective GCLs in the groundwater samples collected from monitoring wells MW-1R, MW-4R, MW-11R, and MW-12. On July 17, 2019, ECS conducted a falling and rising head slug test on monitoring wells MW-1R and MW- 12. Based on the data collected during the slug test, predictive computer modeling using conservative input values indicate that the existing plume of petroleum-related compounds is not expected to be present above laboratory reporting limits or applicable NC2LGWQS no more than 600 feet from the ‘source area’ (monitoring well MW-1R) over a period of 100 years. Therefore, this model demonstrates water supply well WSW-16, located approximately 700 feet downgradient and southeast of the site, is not expected to be impacted by this release. 2.0 SITE GEOLOGY AND HYDROGEOLOGY As determined from the USGS Topographic Map, Middleburg, North Carolina Quadrangle dated 1970 (Figure 1), the site is located at an approximate elevation of 475 feet above mean sea level. Surface runoff on the site is generally to the southeast. The subject site is situated in the Piedmont Physiographic Province. The soils encountered in this area are the residual product of in-place chemical weathering of rock presently underlying the site and/or historic depositional events. In general, shallow unconfined groundwater movement within the overlying soils is controlled largely by topographic gradients. However, as the groundwater percolates downward, it becomes controlled by the subsurface geologic conditions. Thus, the direction of groundwater movement in the deeper aquifers may not be consistent with the reflecting topography. In general, shallow unconfined groundwater movement within the overlying soils is controlled largely by topographic gradients. Recharge occurs primarily by infiltration along higher elevations and typically discharges into streams or other surface water bodies. The elevation of the shallow water table is transient and can vary with seasonal fluctuations in precipitation. Movement of shallow groundwater is generally from higher to lower elevations. Groundwater Monitoring Report – Former Middleburg Grocery Property NCDEQ Incident No. TF-6174 UST No. RA-918 ECS Project No. 49:1638-E 5 3.0 POTABLE WATER SUPPLY SOURCES ECS previously conducted a receptor survey of the surrounding area to determine area receptors. ECS observed several water supply well houses within 1,000 feet of the site. According to the Vance County Water Department, municipal water is provided to the subject site and available to the surrounding areas. Water supply well survey questionnaires were mailed via USPS to the property owners located within 1,000 feet of the source area. ECS received returned surveys from Mr. Ray Bullock (45 N. Lee St.) and Mr. Jay Taylor (6867 Broad Street) stating the properties are connected to municipal water and do not contain water supply wells. ECS received a return survey from Ms. Destry Herring (156 Walnut St.) stating the property is connected to municipal water and contains an inactive water supply well. ECS also received returned surveys from Ms. Dorothy Terry (35 N. Plummer Ave. – WSW-13), Mr. Gary Plummer (88 S. Carroll St. – WSW-10), and Ms. Destry Herring (150 S. Hawkins Ave. – WSW-15) stating the properties contain water supply wells and are not connected to municipal water. According to Mr. Gary Plummer there are two water supply wells located at 88 S. Carroll St. The properties associated with water supply wells WSW-6 and WSW-7 are vacant and the water supply wells are inactive. In addition to the returned water supply well survey letters, information provided by the Vance County Water Department, and historical NCDEQ reports, ECS identified eleven (11) active water supply wells and three (3) inactive water supply wells within 1,000 feet of the source area. A summary of the water supply wells is provided on Table 3 and their locations are shown on Figure 4. 4.0 FIELD ACTIVITIES Monitoring Well Sampling Activities On February 18, 2020, ECS collected a field blank and groundwater samples from monitoring wells MW- 1R, MW-2R, MW-4R, MW-6, MW-12, MW-13, and DW-1. Monitoring wells MW-5 and MW-11R were both observed to be dry and therefore, groundwater samples could not be collected. The locations of the wells are shown on Figure 5. Site photographs documenting field activities are included in Appendix A. Prior to sampling, ECS removed O-SOX from monitoring wells MW-1R and MW-12. Once the O-SOX were removed, ECS allowed the monitoring wells to equilibrate. Then, the static groundwater elevation was measured in each monitoring well using a decontaminated water level meter. A summary of monitoring well construction details and groundwater elevation data are included on Table 4. Based on the groundwater elevations, groundwater flow was determined to be generally to the southeast as shown on Figure 6. Prior to beginning groundwater sampling activities, ECS collected a field blank by pouring DI water over the water level meter probe and into the laboratory prepared sample containers. Purging and sampling were accomplished using a dedicated disposable bailer and nylon string. During purging, ECS collected geochemical measurements from the monitoring wells for each well volume purged using an YSI-556 multi-parameter meter. Immediately after collection, the groundwater samples were transferred into sample containers provided by the laboratory. The geochemical measurements were recorded and included in the monitoring well sampling forms provided in Appendix B. Subsequent to sampling, ECS deployed two (2) new O-SOXs in monitoring wells MW-1R and MW-12. Groundwater Monitoring Report – Former Middleburg Grocery Property NCDEQ Incident No. TF-6174 UST No. RA-918 ECS Project No. 49:1638-E 6 Water Supply Well Sampling Activities On February 18, 2020, ECS collected groundwater samples from water supply wells WSW-1, WSW-2, and WSW-13. The locations of the water supply wells are shown on Figure 4. The water supply wells were purged by discharging water from the wells for approximately 10-15 minutes. After purging was completed, the sampler wearing a new pair of disposable nitrile gloves for each sampling point collected a sample from the exterior spigot on the well. Immediately after collection, the groundwater samples were transferred into sample containers provided by the laboratory. Sample Preparation The sample containers were labeled with ECS project number, sample identification, sample date and time, and requested analytical analysis. The containers were placed into protective packaging material and placed into a cooler with ice to maintain the samples at approximately 4° Celsius (°C). The samples were submitted to Con-Test Analytical Laboratory, a North Carolina certified laboratory located in East Longmeadow, Massachusetts for chemical analysis for Volatile Organic Compounds (VOCs) using Standard Method 6200B. ECS maintained proper chain of custody (COC) procedures throughout the sample collection and transportation process. The laboratory analytical data and the COC are included in Appendix C. 5.0 LABORATORY ANALYTICAL RESULTS Monitoring Well Analytical Results Laboratory analysis reported several targeted analytes at concentrations above their respective NC2LGWQS but below their respective GCLs in the groundwater samples collected from monitoring wells MW-1R, MW-4R, and MW-12. Laboratory analysis reported several additional targeted analytes above their respective laboratory reporting limits but below their respective NC2LGWQS in the groundwater samples collected from monitoring wells MW-1R, MW-4R, and MW-12. Laboratory analysis did not report targeted analytes at concentrations above laboratory reporting limits in the field blank or from monitoring wells MW-2R, MW-6, MW-13 and DW-1. A summary of the current groundwater analytical results from the monitoring wells is included in Table 5 and shown on Figure 6 and an isoconcentration map illustrating the horizontal extent of benzene is shown in Figure 8. Historical groundwater analytical results from the monitoring wells is summarized in Table 6. The laboratory analytical data sheets and COC are included in Appendix C. Water Supply Well Analytical Results Laboratory analysis detected chloroform at a concentration above the laboratory detection limit but below its NC2LGWQS in the groundwater sample collected from water supply well WSW-1. The chloroform detection was denoted with a J-Flag which indicates the compound was detected but below the reporting limit; therefore, it is an estimated concentration. Groundwater Monitoring Report – Former Middleburg Grocery Property NCDEQ Incident No. TF-6174 UST No. RA-918 ECS Project No. 49:1638-E 7 Laboratory analysis did not report targeted analytes at concentrations above laboratory reporting limits from water supply wells WSW-2 and WSW-13. A summary of the current and historical water supply well analytical results is included in Table 7. The laboratory analytical data sheets and COC are included in Appendix C. 6.0 CONCLUSIONS Based on the results of this assessment, ECS concludes the following: • Since the previous O-Sox deployment on June 16, 2019, benzene and EDB concentrations have decreased by 76.9 and 74.7 percent (%), respectively, in the groundwater samples collected from monitoring well MW-1R. Successfully reducing EDB below its GCL. • Laboratory analysis detected chloroform at a concentration above the laboratory detection limit but below its NC2LGWQS in the groundwater sample collected from water supply well WSW-1. The chloroform detection was denoted with a J-Flag which indicates the compound was detected but below the reporting limit; therefore, it is an estimated concentration. It is ECS’s opinion that the result is due to a laboratory contaminant and not a contaminant of the site. • Based on groundwater elevation data, groundwater flows towards the east – southeast away from the closest active water supply well WSW-1. • Previous predictive computer modeling using conservative input values indicated the existing plume of petroleum-related compounds is not expected to be present above laboratory reporting limits or applicable NC2LGWQS no more than 600 feet from the ‘source area’ (monitoring well MW-1R) over a period of 100 years. Therefore, the model demonstrated water supply well WSW-16, located approximately 700 feet downgradient and southeast of the site, is not expected to be impacted by this release. 7.0 RECOMMENDATIONS Based on the results and conclusions of this assessment, ECS recommends conducting two additional groundwater monitoring events for a total of three consecutive groundwater monitoring events to determine if concentrations remain below the GCLs along with continual redeployment of new O-SOX remedial devices in monitoring wells MW-1R and MW-12. If concentrations continue to remain below the GCLs after the after three consecutive groundwater monitoring events, ECS recommends the NCDEQ consider issuing a NRP for soil and groundwater contamination and the NCDEQ should consider issuing a letter of NFA. Additionally, if a NFA is issued ECS recommends abandoning the monitoring wells associated with the site.

For method 6200B elevated reporting limit for samples 20B0870-06+07 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, B252860-BS1, B252860-BSD1 Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits. Reported value for this compound is likely to be biased on the low side. Analyte & Samples(s) Qualified: L-04 Methyl tert-Butyl Ether (MTBE) 20B0870-06[MW-1R], B252860-BLK1, B252860-BS1, B252860-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 20B0870-06[MW-1R], 20B0870-07[MW-12] The results of analyses reported only relate to samples submitted to the Con-Test Analytical Laboratory for testing.

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 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 Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits. Reported value for this compound is likely to be biased on the low side. L-04 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 39 of 45 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 40 of 45 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 41 of 45 Table of Contents Page 42 of 45 Table of Contents Page 43 of 45 Table of Contents Page 44 of 45 Table of Contents Page 45 of 45 Table of Contents
