A Site location map is included as Figure 1. The Site consists of three parcels of land (Parcel Identification Numbers 07108101, 07108102, and 07107805) that total approximately 4.63 acres. The western portion of the Site is developed with an approximately 32,973-square foot (sq ft) industrial building that was constructed in 1952. The building is utilized by Plyler Paper Stock Company to store, sort, bale, and distribute recyclable (primarily paper) products. Historically, the existing Site building was utilized by Clorox as a bleach manufacturing facility from the early 1950s until the late 1980s, when Plyler Paper Stock Company began using the building for the current recycling operation. The eastern portion of the Site consists of a truck/trailer parking lot and undeveloped land. A Site map is included as Figure 2. During recent Phase I ESA activities conducted on the Site, H&H identified the following Recognized Environmental Conditions (RECs): • In March 1990, two soil borings were advanced adjacent to two petroleum aboveground storage tanks (ASTs; specific contents not reported), a former 5,000-gallon heating oil underground storage tank (UST), and a former 2,000-gallon UST (presumed to have contained heating oil) located adjacent to the northeastern corner of the Site building. Total Petroleum Hydrocarbons-Diesel Range Organics (TPH-DRO) were detected in a boring identified as Boring 1 (11 ft) at a concentration of 1,600 mg/kg, which exceeds the 2 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc current North Carolina Department of Environmental Quality (DEQ) UST Section Action Level of 100 mg/kg. A separate heating oil UST release incident was identified in this area in November 1990; however, the soil data pertaining to the release did not indicate TPH-DRO in soil above the DEQ Action Level. The UST release incident received regulatory closure in July 1996. The soil impacts identified in Boring 1 (noted above) do not appear to have been included in DEQ’s evaluation of the UST release and No Further Action determination, and may be associated with the two ASTs. H&H identified the presence of TPH-DRO in soil adjacent to the northeastern portion of the Site building at a concentration above the DEQ Action Level as a REC. • H&H reviewed a Combined Preliminary Assessment/Site Inspection (September 2005) and an Expanded Site Inspection (September 2006) prepared by the DEQ Superfund Section for the former Clorox facility, which included the Site and off-Site properties located north of the Site along State Street. According to the report, the former Clorox facility operated in the northern portion of the Site building from the early 1950s until the late 1980s. No samples were collected on the subject Site during the Preliminary Assessment; however, several soil samples were collected on the Site during the Expanded Site Inspection. Soil analytical data indicated the presence of cadmium (3.7 mg/kg) and mercury (48.09 mg/kg) in sample CLX-009-SS (west side of the building near former rail spur) at concentrations above the Protection of Groundwater Preliminary Soil Remediation Goal (PSRG) of 3.0 mg/kg for cadmium and the Residential PSRG of 14 mg/kg for mercury. The polynuclear aromatic hydrocarbon (PAH) benzo(a)anthracene was detected near northeast exterior corner of the building in samples CLX-009-SS (0.83 mg/kg) and CLX-011-SS (1.1 mg/kg) at concentrations above the Protection of Groundwater PSRG of 0.35 mg/kg in both samples and equal to the Residential PSRG of 1.1 mg/kg in one of the samples. The PAH benzo(a)pyrene was detected in samples CLX-009-SS (0.57 mg/kg) and CLX-011-SS (0.73 mg/kg) at concentrations above the 3 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc Residential PSRG of 0.11 mg/kg. H&H identified the presence of metals and PAHs at concentrations above PSRGs in soil near the northeastern corner of the building as a REC. • Based on review of Sanborn Maps and interviews with Site contacts, Clorox operated a mixing room that was used to manufacture bleach in the northwestern portion of the Site building. The Site owner reported that the room contained multiple ASTs when she purchased the Site in the late 1980s. During Site reconnaissance, H&H observed an earthen floor and a sump in the former mixing room. Previous reports indicate that the bleach manufacturing facility may have included the use of a mercury cell, which produces chlorine-free sodium hydroxide. H&H identified potential environmental impacts associated with bleach manufacturing at the Site from the early 1950s to the late 1980s as a REC. • In 1990, two soil borings (Boring 1 and Boring 2) were advanced adjacent to a concrete basin located adjacent to a rail spur along the western portion of the Site. Previous reports indicate that sodium hydroxide and mercury releases may have occurred from the concrete basin. Analytical data indicated the presence of mercury in a soil sample collected from Boring 1 (0.5 ft) at a concentration of 2.8 mg/kg, which exceeds the protection of groundwater PSRG of 1.0 mg/kg. The measured pH levels in samples collected from Boring 1 and Boring 2 were 13 (2.5 ft) and 13.5 (0.5 ft), respectively, which are elevated (i.e., alkaline) compared to typical soil pH levels in the area and may indicate that a release of sodium hydroxide occurred from the concrete basin. H&H identified the apparent soil impacts in the area of the former concrete basin as a REC. • Worth Chemical Corp. (818 Tuckaseegee Road) operated a chemical distribution facility located approximately 250 ft west and topographically upgradient of the subject Site. H&H reviewed a Site Assessment Work Plan prepared by Arcadis dated December 13, 2010. According to the report, the facility utilized ASTs and USTs for the storage of petroleum products, chlorinated solvents, and other hazardous materials. Results of 4 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc historical soil and groundwater assessment activities conducted at the facility indicated the presence of soil and groundwater impacts associated with releases from the petroleum and chlorinated solvent storage tanks. Based on the documented solvent releases, proximity of the facility to the Site, and area topography, H&H identified the former Worth Chemical Corp. facility and associated releases as a REC for the Site. H&H understands that plans for the Site include commercial redevelopment in accordance with a potential Brownfields Agreement with DEQ. Therefore, H&H conducted Phase II ESA activities at the Site in general accordance with DEQ Brownfields Program guidance to evaluate the potential for the above-mentioned RECs to impact the proposed redevelopment project. The Phase II ESA activities included collection of soil, groundwater, and exterior soil gas samples. The methods and results of the assessment activities are detailed in the following sections. 5 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc 2.0 Phase II ESA Activities Between February 7 and 13, 2019, H&H completed soil, groundwater, and vapor intrusion assessment activities at the Site to evaluate potential impacts associated with historical Site and nearby upgradient property uses. Prior to conducting assessment activities, H&H contacted North Carolina 811, the public utility locator, to mark subsurface utilities on the Site. H&H also contracted with Ground Penetrating Radar Systems (GPRS), a private utility locator, to screen proposed sample locations for subgrade utilities and to confirm public utility locator markings. Additionally, boring locations were hand cleared to approximately 5 ft below the ground surface (bgs) to further screen the boring locations for the presence of subsurface utilities. In accordance with Mecklenburg County regulations, H&H obtained a Subsurface Investigation Permit (SIP No. 70002585) from the Mecklenburg County Land Use and Environmental Services Agency (LUESA) prior to beginning groundwater assessment activities. After sampling was completed, the SIP was closed out by submitting a well abandonment record to LUESA. The assessment activities were conducted in general accordance with the DEQ Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup dated October 2015, DEQ’s Division of Waste Management (DWM) Vapor Intrusion Guidance dated March 2018, and the most recent versions of the U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support (SESD) Field Branches Quality System and Technical Procedures guidance. 6 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc 3.0 Soil Assessment Activities 3.1 Soil Sampling Methodology On February 7 and 8, 2019, H&H contracted Innovative Environmental Technologies (IET), a North Carolina-licensed drilling contractor, to advance nine soil borings (SB-2 through SB-6, and SB-9 through SB-12) using a track-mounted direct push technology (DPT) drill rig and hand auger. Soil boring locations are described below and are depicted on Figure 2. • Soil borings SB-2 and SB-3 were advanced to approximately 5 ft bgs within the former bleach mixing room in the northwestern portion of the building. • Soil boring SB-4 was advanced to approximately 15 ft bgs adjacent to former heating oil USTs/ASTs and previously identified petroleum-related soil impacts in the northern portion of the Site. • Soil boring SB-5 was advanced to approximately 18 ft bgs downgradient of the former bleach manufacturing facility and within a proposed landscaped area located east of the building. • Soil boring SB-6 was advanced to approximately 5 ft bgs within a proposed sub-grade patio on the west side of the building. • Soil borings SB-9 through SB-12 were advanced to approximately 5 ft bgs within a proposed parking lot along the eastern portion of the Site across Gesco Street to evaluate background soil conditions. Continuous soil samples were collected from each boring, logged for lithologic description, and field screened for the presence of staining, odors, and volatile organic vapors using a calibrated photoionization detector (PID). Based upon field screening results, H&H collected one soil sample for laboratory analysis from the depth interval that exhibited the greatest evidence of potential impact (i.e., elevated PID readings, staining, and/or odors). If no obvious indications of soil impacts were observed during field screening, H&H collected a soil sample from approximately 0 to 2 ft bgs to evaluate a potential surface release. 7 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc Soil samples selected for laboratory analysis were placed directly into dedicated laboratory- supplied sample containers; labeled with the sample identification, date, and requested analysis; and placed in a laboratory-supplied sample cooler with ice. The samples were delivered to Pace Analytical Services, LLC (Pace), a North Carolina certified laboratory, under standard chain of custody protocols for analysis of volatile organic compounds (VOCs) by EPA Method 8260B, semi-VOCs (SVOCs) by EPA Method 8270D, Resource Conservation and Recovery Act (RCRA) metals by EPA Methods 6020B/7471B, and hexavalent chromium by EPA Method 7199. 3.2 Soil Analytical Results The soil analytical results were compared to the DEQ IHSB Protection of Groundwater, Residential, and Industrial/Commercial PSRGs dated May 2019. In addition to the PSRGs, metals data were compared to the Site-specific background data, and the range and average background metals concentrations reported in literature for North Carolina soil or southeastern United States soil (if North Carolina data was not available). A tabular summary of soil analytical results is presented in Table 1. The laboratory analytical report and chain of custody record are provided in Appendix B. Laboratory analytical results indicate detections of acetone (0.0121 to 0.167 mg/kg) in the nine soil samples collected for laboratory analysis. The detected acetone concentrations are below the most stringent (i.e., Protection of Groundwater) PSRG. Further, acetone is a common laboratory contaminant; therefore, the detection of trace levels of acetone may not be representative of Site soil conditions. Trace concentrations of the VOCs 2-butanone, toluene, m&p-xylene, chloroform, 4-methyl-2-pentanone, and/or naphthalene were detected each soil sample at concentrations below the Protection of Groundwater, Residential, and Industrial/Commercial PSRGs. Several SVOCs (specifically PAHs) were detected in samples collected in the former bleach mixing room (SB-2 and SB-3) and adjacent to the former heating oil USTs/ASTs (SB-4). Several PAHs were detected above the Protection of Groundwater and Residential PSRGs in sample SB- 8 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc 3 (0-2 ft). Of the PAHs, benzo(a)pyrene (6.81 mg/kg) was detected in SB-3 (0-2 ft) above the Industrial/Commercial PSRG of 2.1 mg/kg. Benzo(a)pyrene was also detected in sample SB-4 (7-9 ft) at an estimated concentration of 0.144 J mg/kg, which exceeds the Protection of Groundwater and Residential PSRGs of 0.12 mg/kg and 0.11 mg/kg, respectively. No SVOCs were detected above the laboratory method detection limits (MDLs) in samples SB-5 (0-2 ft), SB-6 (0-2 ft), or SB-9 (0-2 ft) through SB-12 (0-2 ft). The metals arsenic, barium, chromium (hexavalent and trivalent), lead, mercury, and/or selenium were detected in the nine soil samples analyzed by the laboratory. The arsenic concentrations, which range from 1.42 mg/kg in sample SB-10 (0-2 ft) to 3.07 mg/kg in SB-6 (0-2 ft), exceed the Residential PSRG of 0.68 mg/kg in all nine soil samples and slightly exceed the Industrial/Commercial PSRG of 3.0 mg/kg in sample SB-6 (0-2 ft). The detected concentrations of arsenic in the samples collected from the developed portion of the Site (SB-2 through SB-6) are consistent with arsenic concentrations detected in background samples SB-9 through SB-12. Further, the detected concentrations are below the average published background concentration for North Carolina soils of 4.8 mg/kg. As such, the detected arsenic concentrations appear to be naturally occurring. Hexavalent chromium was detected at estimated concentrations in samples SB-2 (0-2 ft), SB-3 (0-2 ft), SB-6 (0-2 ft), SB-9 (0-2 ft), and SB-11 (0-2 ft) at concentrations ranging from 0.376 mg/kg in SB-11 (0-2 ft) to 0.913 mg/kg in SB-9 (0-2 ft). The detections exceed the Residential PSRG of 0.31 mg/kg. The detected concentrations of hexavalent chromium in the samples collected from the developed portion of the Site (SB-2 through SB-6) are consistent with hexavalent chromium concentrations detected in background samples SB-9 through SB-12. As such, the hexavalent chromium concentrations are likely representative of background conditions. Published background concentrations for hexavalent chromium in North Carolina soils are not available. The remaining metals were detected at concentrations below the Protection of Groundwater, Residential, and Industrial/Commercial PSRGs and generally consistent with published and Site- specific background levels. 9 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc 4.0 Groundwater Assessment Activities 4.1 Groundwater Sampling Methodology On February 7, 2019, IET installed one temporary monitoring well (TMW-2) using DPT drilling methods. The temporary monitoring well (depicted on Figure 2) was installed within boring SB-5 which is located downgradient of the former bleach manufacturing facility. The temporary monitoring well was constructed of 2-inch diameter PVC riser pipe with 10 ft of pre- packed well screen set to bracket the water table. Additional filter sand was placed in the well annulus from the base of the borehole to approximately two feet above the well screen. Hydrated bentonite was installed from the top of the filter pack to approximately 0.5 ft bgs. A temporary monitoring well boring log is provided in Appendix A, and temporary well construction details are provided in Table 2. The approximate depth to groundwater in the well (11.38 ft bgs) was measured using an electronic water level indicator on February 11, 2019. Groundwater flow direction could not be determined with the one temporary monitoring well. However, groundwater elevation data obtained during assessment activities at the upgradient Worth Chemical Corp. facility indicate an easterly flow direction near the Site toward Stewart Creek. The temporary well was developed by removing approximately five volumes of water from the well. The well was purged dry multiple times during development and field parameters did not stabilize (stabilization criteria of pH ± 0.1 SU and conductivity varied no more than 5%). The well development log is provided in Appendix C. After development efforts, the temporary monitoring well was purged using low-flow/low-stress purging techniques using a peristaltic pump and dedicated polyethylene tubing. The intake point of the pump tubing was placed in the approximate mid-portion of the saturated portion of the screened interval of the well, and groundwater was removed at a rate no greater than 200 milliliters per minute. H&H utilized a calibrated water quality meter to collect measurements of pH, temperature, dissolved oxygen, oxidation-reduction potential, turbidity, and specific conductivity during the purging process. Purging was considered complete when the parameters had stabilized (pH ± 0.1 SU, conductivity varied no more than 5%, and 10 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc turbidity was less than 10 Nephelometric Turbidity Units or NTUs). A groundwater sampling form completed by H&H sampling personnel is provided in Appendix C. Following well purging, a groundwater sample was collected for laboratory analyses. The groundwater sample for VOC analysis was collected directly into laboratory supplied sample containers using the “soda straw” method to minimize volatile loss through the peristaltic pump head. The sample containers were labeled with the sample identification, date, and requested analysis, and placed in an iced laboratory supplied cooler. The sample was delivered to Pace under standard chain of custody protocols for analysis of VOCs by EPA Method 8260B, SVOCs by EPA Method 8270D, and RCRA metals by EPA Method 6020B/7470A. For quality assurance/quality control purposes, a trip blank sample was analyzed for VOCs by EPA Method 8260B. Upon completion of soil and groundwater sampling activities, the soil borings and temporary monitoring well boring were abandoned using hydrated bentonite. The ground surface was restored at each boring location to approximately match pre-drilling conditions. Soil cuttings and well development/purge water generated during Phase II ESA activities were spread on-Site, as obvious evidence of significant impact (such as free product) was not observed. 4.2 Groundwater Analytical Results Groundwater data were compared to the 2L Standards and the DEQ DWM Residential and Non- Residential Groundwater Vapor Intrusion Groundwater Screening Levels (GWSLs) dated February 2018. A tabular summary of groundwater analytical results is presented in Table 3. The laboratory analytical report and chain of custody record are provided in Appendix B. Benzene (3.3 µg/l) and vinyl chloride (0.77 J µg/L) were detected in sample TMW-2 at concentrations above the 2L Standards of 1.0 µg/L and 0.03 µg/L, respectively, but below the Residential and Non-Residential GWSLs. Several other VOCs were detected in TMW-2 at concentrations below the 2L Standards and below the Residential and Non-Residential GWSLs. No VOCs were detected above the MDLs in the trip blank. 11 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc No SVOCs were detected above the MDLs in sample TMW-2. The metals arsenic (0.503 J µg/L), barium (238 µg/L), chromium (2.41 µg/L), and lead (0.254 J µg/L) were detected in sample TMW-2 at concentrations below the respective 2L Standards of 10 µg/L, 700 µg/L, 10 µg/L, and 15 µg/L. 12 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc 5.0 Vapor Intrusion Assessment Activities On February 13, 2019, H&H collected two exterior soil gas samples (SG-1 and SG-2) to evaluate the potential for vapor intrusion into the Site building from potential groundwater impacts associated with the upgradient former Worth Chemical facility. The temporary soil gas points were installed between a former rail spur and the western exterior wall of the former Clorox facility, as shown on Figure 2. 5.1 Exterior Soil Gas Sampling Methodology Borings for exterior soil gas points SG-1 and SG-2 were advanced to depths of 6.5 and 7.5 ft bgs, respectively, using a hand auger. The borings were terminated at depths interpreted to be within one foot of the capillary fringe based on field observations. Continuous soil samples were collected from each boring, logged for lithologic description, and screened for the presence of staining, odors, and volatile organic vapors using a calibrated PID. Boring logs are provided in Appendix A. Each exterior soil gas point was constructed with a six-inch long stainless-steel screen point installed at the base of the boring and fitted with ¼-inch diameter Teflon® tubing that extended to the ground surface. Filter sand was then installed around the soil gas point from the base of the boring to approximately six-inches above the top of the screen. The sampling points were completed by placing hydrated bentonite from the top of the filter sand to approximately 0.5 ft bgs. After installation, a leak check was conducted at each soil gas sample location by constructing a shroud around the sampling point and flooding the shroud with helium gas. Helium concentrations inside the shroud were measured using a helium gas detector. Using a peristaltic pump and three- way valve, approximately three volumes of air within the Teflon tubing and soil gas point borehole annular space were purged. Following purging, a sample was collected into a Tedlar bag from the soil gas point and field screened using the helium gas detector to ensure that helium concentrations in the soil gas point were less than 10% of the helium concentrations in the shroud. A soil gas sampling QA/QC form that provides leak test results is included in Appendix D. 13 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc Following a successful leak check, a laboratory-supplied 1-liter stainless steel Summa canister connected to an in-line flow controller with a vacuum gauge was connected to the tubing at each sampling point using a brass nut and ferrule assembly to form an air-tight seal. The flow regulator was pre-set by the laboratory to regulate the vapor intake rate to approximately 100 milliliters per minute. Once the sample train was assembled, the intake valve on the canister was fully opened to begin collection of the soil gas sample. Vacuum in each of the canisters was measured using a laboratory-supplied vacuum gauge prior to and after collection of the soil gas samples. These measurements were recorded on the sample chain of custody. Per laboratory standard operating procedures, a vacuum was maintained within the canisters at the conclusion of the sampling event. After sample collection, the Summa canister’s valve was closed prior to the regulator being disconnected from the canister. The Summa canisters were then placed in laboratory-supplied shipping containers, properly labeled, and shipped under standard chain of custody protocols to Con-Test Analytical Laboratory (Con-Test), a North Carolina certified laboratory, for analysis of VOCs by EPA Method TO-15. Upon completion of sampling activities, each exterior soil gas sampling point was abandoned, and the surface was repaired to approximately match pre-drilling conditions. 5.2 Exterior Soil Gas Analytical Results Soil gas analytical results were compared to the February 2018 DEQ DWM Residential and Non- Residential Sub-Slab and Exterior Soil Gas Screening Levels (SGSLs). Results of soil gas analysis are summarized in Table 4. The laboratory analytical report and chain of custody record are provided in Appendix B. Laboratory analytical results indicate the presence of several low concentrations of VOCs, including chlorinated and petroleum-related compounds, in soil gas samples SG-1 and SG-2. The VOC detections were generally higher in sample SG-1 compared to SG-2. None of the detected compounds were reported at concentrations exceeding Residential or Non-Residential SGSLs. 14 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc 6.0 Conclusions and Recommendations H&H has completed Phase II ESA activities at an industrial property located at 800 Gesco Street in Charlotte, Mecklenburg County, North Carolina. The assessment activities were conducted in general accordance with DEQ and EPA guidance and included soil, groundwater, and exterior soil gas sampling to evaluate potential environmental risks that may affect Site redevelopment. A summary of the assessment results is provided below. Soil H&H collected nine soil samples for laboratory analysis to evaluate the potential for soil impacts at the Site. Samples were collected in areas of previously identified RECs and areas of potential soil disturbance as part of Site redevelopment. Laboratory analytical results do not indicate the presence of VOCs in soil samples at concentrations above the DEQ PSRGs. PAHs were detected at concentrations exceeding Protection of Groundwater, Residential, and/or Industrial/Commercial PSRGs in a shallow sample (0-2 ft) collected in the former bleach mixing room. The PAH benzo(a)pyrene was also detected above the Protection of Groundwater and Residential PSRG in one sample collected at 7-9 ft bgs adjacent to former heating oil USTs/ASTs. Arsenic was detected at concentrations above the Residential PSRG in the nine soil samples collected for laboratory analysis and slightly above the Industrial/Commercial PSRG in one sample. The detected concentrations of arsenic in the samples collected from the developed portion of the Site are consistent with arsenic concentrations detected in the background samples. Further, the detected concentrations are below the average published background concentration for North Carolina soils. As such, the detected arsenic concentrations appear to be naturally occurring. Hexavalent chromium was detected at estimated concentrations in samples SB-2 (0-2 ft), SB-3 (0-2 ft), SB-6 (0-2 ft), SB-9 (0-2 ft), and SB-11 (0-2 ft) above the Residential PSRG. The detected concentrations of hexavalent chromium in the samples collected from the developed portion of the Site are consistent with hexavalent chromium concentrations detected in 15 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Phase II ESA - Revised\Report\Phase II ESA - Former Clorox Facility (7-3-19).doc background samples. As such, the hexavalent chromium concentrations are likely representative of background conditions. Groundwater H&H installed and sampled one temporary groundwater monitoring well (TMW-2) located downgradient of the Site building. Concentrations of benzene and vinyl chloride detected in TMW-2 exceed the 2L Standards, but are below Residential and Non-Residential GWSLs. No SVOCs were detected in sample TMW-2 above the MDLs, and no metals were detected in sample TMW-2 at concentrations above the 2L Standards. Exterior Soil Gas H&H collected two soil gas samples (SG-1 and SG-2) near the western exterior wall of the former Clorox facility. VOCs were detected in the exterior soil gas samples at concentrations below the Residential and Non-Residential SGSLs.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. MDL (dry)Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J3 The associated batch QC was outside the established quality control range for precision. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Pace Analytical - Huntersville, NC 92417206 L1069045 06/25/19 13:42 22 of 26 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Pace Analytical - Huntersville, NC 92417206 L1069045 06/25/19 13:59 22 of 26 Page 87 of 91 ONE LAB.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Pace Analytical - Huntersville, NC 92417688 L1070848 06/26/19 13:24 8 of 11 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Pace Analytical - Huntersville, NC 92417688 L1070848 06/26/19 13:57 8 of 11 Page 40 of 43 ONE LAB.
