Full-scale activities were initiated on September 10, 2013. Wells IW-1A, IW-2, IW-4, IW-5A, IW-6, and IW-7A were used for injection and wells EW-8, EW-9 (replaced by EW-9A in April 2016), and EW-10 were used for extraction. The system was shut down on August 19, 2020, and one year of quarterly monitoring at select downgradient monitoring wells and water supply wells is scheduled to begin in November 2020. Any significant changes in the subsurface conditions? If Yes, provide details in the space below: 0 Yes ® No Quality Assurance/Quality Control Procedures GWMR Form 2 DSCA ID No.: DC920001 Describe the standard quality assurance/quality control (QA/QC) procedures which are practiced in order to ensure that the samples are representative of actual conditions and that analytical results are valid. Standard low flow sampling procedures and methods were utilized for sampling groundwater at the site. The water level and water quality meters were decontaminated using LiquiNox detergent and distilled water after each well was gauged, measured, and/or pumped to avoid cross -contamination New nitrile gloves and purge/sample tubing (both polyethylene and silicone) were used at each well. Groundwater samples for volatiles analysis were collected in three 40 milliliter vials preserved with hydrochloric acid and filled to zero headspace for each monitoring well. Each sample was labeled with the site and sample identifications, time, date, sampler's initials, and analysis method. Samples were secured in protective wrap or bags before being covered with ice and cooled to 4 degrees Celsius in a laboratory -supplied sample cooler. A chain -of -custody form was completed for the sampling event and accompanied the samples to the laboratory. Chemical analyses were performed on groundwater samples by Con -Test Analytical Laboratory (Con -Test) in East Longmeadow, Massachusetts. All groundwater samples were analyzed for volatile organic compounds (VOCs) by EPA Method 8260. Samples were also analyzed in the field for pH, oxidation/reduction potential, specific conductivity, dissolved oxygen, and temperature. Describe the specific sampling technique employed during the collection of all ground water samples. Groundwater samples were collected from the monitoring wells using low flow sampling methods. Well purging and sampling were completed using a two-inch bladder pump with a 120-volt control box. The polyethylene tubing was replaced at each monitoring well location prior to sampling. Field parameters, including pH, oxidation/reduction potential, specific conductivity, dissolved oxygen, and temperature, were measured every three to five minutes using a YSI multimeter and flow -through cell. Before obtaining a sample using the EPA -approved "soda straw" method, field parameters were allowed to stabilize within EPA guidelines to ensure a representative groundwater sample was collected. The bladder pumps were decontaminated with LiquiNox, distilled water, and isopropyl alcohol prior to purging and sampling of each monitoring well. Note that well MW-10B was purged dry before field parameters were able to stabilize and groundwater did not readily recharge. A grab groundwater sample was collected from the well for laboratory analysis. Additionally, MW-11B contained less than one foot of groundwater, and a grab sample was collected from the well with a bailer for field and laboratory analysis. Describe the EPA approved methods used to extract and analyze the samples submitted the laboratory. Reference the maximum holding time for each type of analysis performed. Laboratory analyses were performed for VOCs by EPA Method 8260D by Con -Test. The maximum holding time for VOC analysis is 14 days from the sample collection date (when the sample is preserved in HC1). The samples were analyzed within this timeframe.

Table 1: Site Chronology ADT 1 DSCA ID No.: DC920001 Chronology of E% ents Date Instructions: Brief description of all significant events that have occurred since a problem was suspected at the facility. Commence with the first date a problem was suspected and continue through the most recent activity described in the current report. Late 1994 or Early 1995 (report not provided) A Phase I Environmental Site Assessment (ESA) was prepared by Smith Environmental Technologies (Smith). This ESA identified Pro -Cleaners as a potential environmental concern. June 1995 A Phase II ESA was prepared by Smith. Three 2-inch monitoring wells (MW-1, MW-2, & MW-3) were installed at the site and three hand auger borings (CS-01, CS-02, & CS-03) were advanced within the former dry-cleaning location. Groundwater samples collected from MW-1 (located along the western wall of the building) indicated tetrachloroethylene (PCE) and trichloroethylene (TCE) at concentrations of 1,000 ppb and 24 ppb, respectively. The average depth -to - groundwater was documented to be —29 feet bgs. PCE was detected in each of the soil borings (advanced to 3 feet with samples collected from 1 foot bgs and at 3 feet bgs) at concentrations ranging from 240 ppb to 21 ppb. December 1995 An ESA was prepared by Southeastern Environmental Services, Inc. (SES). The field assessment included the installation of four monitoring wells (MW-4 through MW-7), collection/analysis of Shelby tube samples, and the collection/analysis of groundwater samples. The four wells were installed to varying depths ranging from 68.5 feet bgs (MW-5) to 70 feet bgs (MW-4, MW-6, & MW-7). Shelby tube samples were collected during the installation of MW-7 at depths of 29.5-31.5 feet bgs and 37.5-39.5 bgs and analyzed for vertical and horizontal hydraulic conductivity. The analysis revealed horizontal and vertical hydraulic conductivities of 0.000091 cm/sec and 0.000018 cm/sec, respectively, in the sample collected from above the water table; the analysis also revealed horizontal and vertical hydraulic conductivities of 0.000017 cm/sec and 0.0000079 cm/sec, respectively, in the sample collected from below the water table. Groundwater samples were also collected from five monitoring wells (MW-1 and MW-4 through MW-7) at the site. PCE was detected in MW-1 at a concentration of 3410 ppb; PCE was detected in MW-4 at a concentration of 204 ppb; and, PCE was detected in MW-5, MW-6, MW-7 at concentrations ranging from 28 ppb to 11 ppb. Groundwater was also identified as a source for drinking water in the area of the site; a water supply well was identified approximately 250 feet north of the site. July 1996 An ESA Addendum and Remedial Action Plan were prepared by SES and Walton Engineering (Walton). Two additional monitoring wells were installed at the site: MW-8 was installed to a depth of 83 feet bgs and MW-9 was installed to a depth of 63 feet bgs. Groundwater samples were collected from eight monitoring wells at the site. PCE was detected in the samples collected from MW-1 (2895 ppb), MW-4 (663 ppb), and MW-8 (142 ppb). Samples collected from MW-3, MW-5, MW-6 MW-7, and MW-9 did not contain PCE. Samples collected from MW-1 and MW-4 included breakdown chlorinated compounds (TCE and cis-1,2-dichloroetylene [cis-1,2-DCE]). Water samples were collected from three water supply wells; chlorinated solvents were not detected in these samples. The Remedial Action Plan of this report discusses the implantation of several remedial technologies. The report concludes that the most effective remediation technology for the site would be a combination of air sparging with vapor extraction. Design schematics and operation and maintenance schedules were provided. The system became was installed and became operational on June 7, 1996. February 1997 A Site Assessment Addendum was prepared by SES and Walton. Four additional monitoring wells were installed on the north side of Strickland Road. Monitoring well MW-10A was installed to a depth of 80 feet bgs; monitoring well MW- 10B was installed at a depth of 45 feet bgs; MW-11A was installed to a depth of 104 feet bgs; and MW-11B was installed to a depth of 35 feet bgs. PCE was detected in groundwater samples collected from MW-1 (1744 ppb), MW-4 (260 ppb), MW-5 (8.6 ppb), MW-7 (8.7 ppb), MW-8 (347 ppb), and MW-9 (2.2 ppb). Samples collected from MW-1, MW-4, and MW-8 included breakdown chlorinated compounds (TCE and cis-1,2-DCE). Chlorinated compounds were not detected in MW-3, MW-6, MW-10A, MW-10B, MW-11A, MW-11B, or the three residential water supply wells sampled during this event. SES and Walton stated that the remediation system appeared to be reducing the solvent concentrations in the source area. April 1997 A Site Assessment and Corrective Action Plan Addendum were prepared by SES and Walton. Six additional monitoring wells (two were temporary and abandoned) were installed at the site. Monitoring well MW-8A was installed to a depth of 151 feet bgs. Monitoring wells MW-12, MW-13, MW-14 (abandoned), MW-15 (abandoned), and MW-16 were installed to a depth of 40 feet. Laboratory analysis of groundwater samples revealed the presence of PCE in MW-1 (3380 ppb), MW-4 (50.6 ppb), MW-5 (4.4 ppb), MW-7 (1.9 ppb), MW-8 (194 ppb), MW-8A (271 ppb), MW-9 (2.4 ppb), MW- 14 (10 ppb), MW-15 (29.6 ppb) and MW-16 (43.0 ppb). Breakdown chlorinated compounds were also detected in MW- 1, MW-8, MW-8A, and MW-15. Chlorinated solvents were not detected in MW-3, MW-10A, MW-10B, MW-11A, MW- 11B, MW-13, or the three residential water supply wells sampled during this event. Chlorinated compounds were not detected in the soil samples collected during the installation of MW-12, MW-13, and MW-14 from 20 feet bgs. Slug testing at the site during this assessment indicated an average hydraulic conductivity of 0.00067 cm/sec in the intermediate zones and 0.000425 in the deep zone. Two additional air sparge wells were constructed north of MW-8.

Commence with the first date a problem was suspected and continue through the most recent activity described in the current report. September 1997 A Final Corrective Action Plan Addendum was prepared by SES and Walton. This addendum was prepared to address concerns of the NCDENR regarding the off -site migration of the plume to the southwest and other various technical and administrative issues. March 1998 A Groundwater Monitoring Report was prepared by SES and Walton. Monitoring well MW-17 was sampled for the first time during this sampling event, however a discussion regarding the installation was not provided. Groundwater samples were collected from 18 monitoring wells and three water supply wells. Concentrations of chlorinated compounds increased drastically in samples collected from MW-1. No significant changes in contaminant concentrations were observed in samples collected from MW-4 or noted for the remainder of the monitoring wells or water supply wells. It was noted in this report that Pro -Cleaners moved to another tenant space within Towne North Shopping Center and dry- cleaning operations ceased on the property. June 1998 An Active Remediation Groundwater Monitoring Report was prepared by SES and Walton. Groundwater samples were collected from 18 monitoring wells, three water supply wells, and one private utility supply well. Concentrations of chlorinated compounds continued to show increasing values in MW-1. Additionally, samples collected from MW-8, MW 8A, and MW-10A also showed increased concentrations of chlorinated compounds. January 1999 An Active Remediation Groundwater Monitoring Report was prepared by SES and Walton. Groundwater samples were collected from 15 monitoring wells and three private water supply wells. The results revealed a decrease in concentration of chlorinated compounds from the previous sampling event. April 1999 An Assessment Addendum and Active Remediation Groundwater Monitoring Report was prepared by SES and Walton. Three temporary monitoring wells were installed (MW-18, MW-19, and MW-20). Monitoring well MW-18 was abandoned based on the analytical data; wells MW-19 and MW-20 were made permanent. Groundwater samples were collected from 18 monitoring wells and three water supply wells. The plume geometry remained unchanged and volatile organic compounds (VOCs) were not detected in the samples collected from the three water supply wells. August 1999 An Active Remediation Groundwater Monitoring Report was prepared by SES and Walton. Groundwater samples were collected from 15 monitoring wells and three private water supply wells. The results indicated an unchanged plume geometry and increase in concentrations in samples collected from monitoring wells MW-10B and MW-11B; VOCs were not detected in the samples collected from the three water supply wells. December 1999 An Active Remediation Groundwater Monitoring Report was prepared by SES and Walton. Groundwater samples were collected from 15 monitoring wells and three water supply wells. The results indicated a narrowing of the groundwater plume and unstable concentrations in samples collected from MW-10B and MW-11B; VOCs were not detected in the samples collected from the three water supply wells. May 2000 An Active Remediation Groundwater Monitoring Report was prepared by SES and Walton. Groundwater samples were collected from 15 monitoring wells and three water supply wells. The results indicated stable plume geometry and concentrations from the samples were generally consistent with the previous sampling event. The sample from the water supply well located at 8401 Azalea contained a low concentration (1.16 ppb) of 1,2,4-trimethyl benzene. No other VOCs were detected in the samples collected from the three water supply wells. October 2000 An Active Remediation Groundwater Monitoring Report was prepared by SES and Walton. Groundwater samples were collected from 15 monitoring wells and three water supply wells. The results indicated stable plume geometry and concentrations from the samples were either decreased or stable; VOCs were not detected in the samples collected from the three water supply wells. April 2001 An Active Remediation and Groundwater Monitoring Report was prepared by SES and Walton. Groundwater samples were collected from 17 monitoring wells and three water supply wells. The results indicated stable plume geometry and contaminant concentrations; VOCs were not detected in the samples collected from the three water supply wells. August 2001 Northridge Partners filed a Petition for Certification of the site into the DSCA Program. October 2001 The air sparge/soil vapor extraction system was taken out of service. December 2001 The site was certified into the DSCA program. October 2003 A Groundwater Monitoring Report was prepared by MACTEC Engineering and Consulting, Inc. (MACTEC). Groundwater samples were collected from ten monitoring wells and three water supply wells. The results indicated stable plume geometry and varying (increasing to the south-southwest and decreasing in the source and north of the source area) concentrations of VOCs. TCE and cis-1,2-DCE were detected in the sample collected from the water supply well located at 8400 Camellia Drive; VOCs were not detected in the samples collected from the other water supply wells. December 2004 An Administrative Agreement for State -Directed Assessment and Remediation under the DSCA Program was executed.

Contaminant concentrations increased in the sample collected from 8400 Camellia Drive; the remaining two water supply wells did not contain VOCs. July 2005 A Report of Water Supply Well Sampling Event was prepared by Engineering Consulting Services, Ltd. (ECS). Groundwater samples were collected from ten water supply wells. No chlorinated compounds were detected in the samples collected. October 2005 Towne North Shopping Center, LLC purchased the Towne North Shopping Center property and became a DSCA petitioner. April 2006 A Report of Soil Assessment and Groundwater Monitoring was prepared by MACTEC. Soil samples were collected from soil borings S-1 through S-16 and from the boring associated with the installation of MW-1d; the soil samples were collected from varying depths. The results indicated high concentrations of PCE in soil outside the building in the area of the rear door and along the sewer and water lines near the rear of the facility. One Type -II monitoring well (MW-21) was installed to replace MW-20; one Type -III monitoring well (MW-1d) was installed immediately downgradient of the source area. Monitoring wells MW-6 and MW-20 were abandoned. Groundwater samples were collected from 12 monitoring wells and 18 water supply wells. The results indicated stable plume geometry and generally increasing contaminant concentrations. The sample collected from the water supply well located at 8400 Camellia Drive contained TCE and cis-1,2-DCE. The sample collected from the water supply well at 8404 Camellia Drive contained cis-1,2-DCE. No other samples contained chlorinated solvent compounds.

SECTION V. CONTACT NAME AND DATE On behalf of DSCA Petitioner Site CC9y47047 Print Name: Niki..1t1 G `5��X\Un ` y►.-tl V � Date: 55v j/,0 KEY TERMS/DEFINITIONS CLASS I SDWA SYSTEM means a Class f deep well facility regulated under the Safe Drinking Water Act (SDWA). CWA SYSTEM means a centralized wastewater treatment facility discharging under a Clean Water Act (CWA) permit. For example, a CWA facility would treat organic or inorganic aqueous wastes and discharge the treated effluent to the loca€ sewer system. Examples of CWA treatment systems owned and operated by Clean Harbors include the wastewater treatment operations at Baltimore (including the CES system), Bristol, Chicago, Cincinnati and Cleveland. CWA-EQUIVALENT SYSTEM means a "zero discharge system" that engages in 'CWA-equivalent" treatment before land disposal. Zero - discharge facilities treat hazardous wastes using "CWA-equivalent" treatment methods, but do not discharge the treatment effluent to a sewer or water body (e.g., spray irrigation land farm), "CWA-equivalent" treatment methods means biological treatment for organics, alkaline chlorination, or ferrous sulfate precipitation for cyanide, precipitation/ sedimentation for metals, reduction of hexavalent chromium, or other treatment technology that can be demonstrated to perform equally or greater than these technologies. HIGH TOC IGNITABLE LIQUIDS SUBCATEGORY means an ignitable liquid hazardous waste (waste code D001) which contains greater than or equal to 10% total organic carbon (TOC). Pursuant to 40 CFR 268.40, such wastes must be treated using organic recovery (RORGS) or combustion (CMBST) technology. Examples of RORGS technologies inolude the CES unit at Clean Harbors of Baltimore. Examples of CMBST technologies include hazardous waste fuel blending and subsequent reuse at a cement kiln, or destruction at a RCRA incinerator. WASTEWATERS are wastes that contain less than 1 % by weight total organic carbon (TOC) and less than 1 % by weight total suspended solids (TSS).

outside of established limits. t Wide recovery limits established for difficult compound. $ Wide RPD limits established for difficult compound. Data exceeded client recommended or regulatory level ND Not Detected 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 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. Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated concentration (CLP J-Flag). V-06 Continuing calibration verification (CCV) did not meet method specifications and was biased on the high side for this compound.
