Objectives: After final grading of the Site, collect samples of exposed soil at four locations. Analyze soils samples for the following: volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and RCRA metals, including arsenic, barium, cadmium, chromium (speciated), mercury, lead, selenium, and silver. Summary: On July 17, 2018, after final grading of the Site was completed, AECOM collected samples of exposed soil from four locations (SB-1, SB-2, SB-3, and SB-4). These locations are shown on the attached Soil Sampling Locations Map. Sample locations were selected in the vicinity of former dry-cleaning operations and remediation to represent the maximum risk. Soil samples were collected from the surface (0” to 6”) using a stainless-steel hand auger and were submitted to SGS Accutest of Orlando, FL for analysis of VOCs, SVOCs, and eight RCRA metals, consistent with the Environmental Management Plan (EMP) for the site. Soil sampling results are present in the attached Soil Analytical Results Table. Arsenic exceeded the NC Residential Health-Based Preliminary Soil Remediation Goal (Soil PSRG) at all four sampling locations. Chromium was detected in all four samples as well, but the speciated analyses indicated that hexavalent chromium was present at less than 1 mg/kg in each sample. VOCs detected included tetrachloroethylene (PCE) and cis-1,2-dichloroethylene (cDCE), which relate to historic dry-cleaning activity at the site. Discussion: The North Carolina Department of Environmental Quality (NCDEQ), has calculated a site specific protection of groundwater value of 138 µg/kg for PCE under the Dry-Cleaning Solvent Clean-up Act [URS Corporation, February 2017]. All detections were below this result. Date: Monday, July 30, 2018 To: Tracy Wahl (NC Brownfields – Asheville Regional Office) CC: John Condray and Jimmy Clay (Town of Forest City) From: Conan Fitzgerald (AECOM) Subject: Results of Final Grade Sampling – Forest City Brownfields Project Site Page 2 of 5 The metals analysis results are similar to the borrow material analyses results submitted to the NCDEQ Brownfields department by email on August 8, 2017. The average arsenic result for the final grade samples is slightly less than the average result for the borrow material, while all of the final grade hexavalent chromium results are less than their corresponding analyses in the borrow material. Conclusions: Final Grade sampling indicates that the exposed soil is safe for unrestricted use at the site. The metals detected are consistent with the background concentrations detected in the borrow soil approved for use at the site. VOCs detected are below residential health based criteria, as well as the site specific protection of groundwater value for PCE.

Surrogate (S1, S2, S3 etc.): are positive controls that are used in most organics methods to ascertain preparation  efficiency and matrix effect in individual samples. These chemicals mimic common method constituents but are  unlikely to be found in real samples. Recoveries can be reported for every analytical run used in the analysis.  IS (Internal Standard IS1, IS2, IS3, etc):

Samples were intact and chemically preserved, unless noted below. A SGS North America Inc. Job Number of FA55659 was assigned to the project. Laboratory sample ID, client sample ID and dates of sample collection are detailed in the report’s Results Summary Section. Specified quality control criteria were achieved for this job except as noted below. For more information, please refer to the analytical results and QC summary pages. Client:SGS Orlando, FL Site:URSNCM: Forest City, NC Job No FA55659 Report Date 7/16/2018 5:56:30 PM CASE NARRATIVE / CONFORMANCE SUMMARY Compounds qualified as out of range in the continuing calibration summary report are acceptable as per method requirements when there is a high bias but the sample result is non-detect. General Chemistry By Method SW846 3060A/7196A Matrix:SO Batch ID:GP14493 All samples were prepared within the recommended method holding time. All method blanks for this batch meet method specific criteria. Sample(s) FA55659-1DUP, FA55659-1MS were used as the QC samples for Chromium, Hexavalent. Matrix Spike Recovery(s) for Chromium, Hexavalent are outside control limits. Soluble XCR matrix spike recovery indicates possible matrix interference. Good post spike recovery (105%) on this sample. SGS North America Inc. certifies that data reported for samples received, listed on the associated custody chain or analytical task order, were produced to specifications meeting the Quality System precision, accuracy and completeness objectives except as noted. Estimated non-standard method measurement uncertainty data is available on request, based on quality control bias and implicit for standard methods. Acceptable uncertainty requires tested parameter quality control data to meet method criteria. SGS North America Inc. is not responsible for data quality assumptions if partial reports are used and recommends that this report be used in its entirety.
