A site location map and site layout map are included as Figure 1 and Figure 2, respectively. Please note that assessment activities were performed by Altamont Environmental, Inc. (Altamont) which became Anchor QEA on December 29, 2016. For report clarity, Altamont is referred to as Anchor QEA hereafter. According to Mecklenburg County geographic information system (GIS) the Site is currently owned by Park Ministries Inc. Assessment activities were performed to evaluate the suitability of the Site for use as a proposed switching station and to evaluate soil and groundwater conditions. A Site background and summary of assessment methodology, results, potential receptor survey, and conclusions is included in the following sub-sections. 1.1 Background Historical Site assessments have included a Phase I Environmental Site Assessment (ESA) completed by S&ME, dated December 4, 2015 as well as a draft Limited Phase II ESA, also completed by S&ME, dated March 10, 2016 (S&ME 2015 and 2016). The Site is an approximately 7-acre tract including a 0.943-acre access easement that will be sub-divided from a larger 45-acre parcel. In its Phase I ESA, S&ME identified one recognized environmental condition (REC) as follows: • One permitted land clearing and inert debris (LCID) landfill, referred to as 60-AW, is located on the Site and a second LCID landfill, referred to as 60-X, is located adjacent to the Site, to the south. Additionally, the results of a file review indicated that the on-site landfill had received inappropriate waste, including petroleum-impacted soil. Other pertinent information included in the Phase I ESA is as follows: • The on-site landfill was permitted in 1994 and closed in 1997. • Three existing monitoring wells were observed on a site map; only two wells were observed during a Site visit (one of which appeared to be damaged). The results of the Limited Phase II ESA indicated the following: • A geophysical survey indicated that fill material was placed over most of the Site. • Two of the existing wells were found to be dry and the third was damaged; so no groundwater data was obtained. These wells continue to be dry. Brownfield Site Assessment 2 January 2017 • Five soil samples were collected from 14 direct-push borings installed on-site and analyzed for volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs). • Fill thickness ranged from no fill to as much as 35.5 feet. • Fill was composed of soil, wood, with some asphalt and gravel. • Soil analytical results indicated the presence of VOCs and SVOCs. However, only naphthalene in one sample was detected at a concentration in excess of an applicable standard (the North Carolina Department of Environmental Quality [DEQ] Protection of Groundwater Soil Remediation Goal [PSRG]). 1.2 Site Geology and Setting The Site is located in Mecklenburg County, North Carolina, within the Piedmont physiographic province of North Carolina. The Piedmont is a relatively broad strip extending from central Alabama across Georgia and the Carolinas into Virginia. According to the Geologic Map of North Carolina, rock types in the area include metamorphic gneiss and schist with some granite intrusions (North Carolina Geologic Survey 1985). The majority of bedrock in the Piedmont is overlain with residual soil and saprolite of varying thickness. Topographic data shown on Figure 1 indicates that Site elevation ranges from approximately 550 feet to 540 feet (National Geodetic Vertical Datum 1929). The Site is located on a topographic high. Groundwater from the Site likely flows to the northwest, north, and east, eventually discharging to McAlpine Creek. Based on historic Site data (as shown on Figure 3), LCID was mainly placed in a gulley on the northwest area of the Site. In this area, groundwater is expected to flow only to the north and northwest, although groundwater flow direction has not been confirmed. LCID fill is composed of soil, wood, with some asphalt and gravel. Soil in areas without fill are composed primarily of topsoil underlain by saprolite, with perhaps some areas of re-worked soils. Brownfield Site Assessment 3 January 2017 2 Assessment Methodology A description of assessment methodology is included in the following sub-sections. Well construction information is included in Table 1. Boring logs and well construction records are included as Appendix A and monitoring well sampling logs are included in Appendix B. A Site Layout Map and Sample Location Map are included as Figures 2 and 3, respectively. 2.1 Utility Location and Health and Safety Anchor QEA prepared a Site-specific Health and Safety Plan (HASP) for field use. The HASP was reviewed by Anchor QEA employees, contractors and Site visitors prior to initiating work activities. A daily tailgate meeting was held with Anchor QEA employees and Site contractors in order to identify and mitigate potential Site hazards associated with that day’s activities. Additionally, field personnel participated in a mid-day and end-of-day wellness check to ensure that health and safety procedures were appropriate and effective for preventing injuries. Prior to engaging in intrusive activities, Anchor QEA contacted the North Carolina One-Call Center to identify public utilities at the Site. Due to the nature of the Site (a former landfill) and the previous geophysical report prepared by S&ME’s subcontractor, the presence of unknown utilities was unlikely. However, to further reduce the risk of encountering unknown sub-surface hazards, Anchor QEA subcontracted a private utility locator to clear Site boring locations using ground-penetrating radar (GPR) and/or similar geophysical techniques. Additionally, prior to intrusive activities, all boring/well locations were “cleared” by advancing a hand auger or post-hole digger to at least 5 feet below ground surface (ft-bgs). 2.2 Soil Assessment To further assess soil quality in the area of the proposed switching station as well as in landfill LCID material, Anchor QEA advanced three soil borings in the western half of the proposed switching station and collected soil samples from monitoring well borings in other areas of the Site. The purpose of soil borings SB-1, SB-2, and SB-3, as well as soil collected from OW-1 is to provide some additional soil quality data in the proposed substation area, as Site workers may encounter this soil during grading/construction activities. An Anchor QEA field geologist observed all soil borings and screened soil with a photoionization detector (PID) for organic vapor content. Soil cores in monitoring well locations were also field- screened. South Atlantic Environmental Drilling and Construction Co. Inc. (SAEDACCO), a North Carolina- licensed well driller, performed drilling activities and collected continuous soil cores from soil boring SB-1 and monitoring well locations OW-1, OW-2, and OW-3 using sonic drilling techniques. Soil Brownfield Site Assessment 4 January 2017 cores were collected via dedicated sleeves in 10-foot intervals. Soil borings SB-2 and SB-3 were advanced to only 2 ft-bgs and were collected with a hand auger. Monitoring wells OW-2 and OW-3 were installed into LCID material. In these locations, samples were collected based on elevated PID readings or other visual/olfactory indications of potential impacted media. A sample was collected from 5 to 8 ft-bgs and 15 to 20 ft-bgs from the OW-2 boring and from 17 to 18 ft-bgs in the OW-3 boring. Boring material in these locations was primarily woody debris with some soil and occasional concrete and asphalt. In both of these locations, approximately 5 feet of soil was observed covering LCID material. Soil borings SB-1, SB-2, SB-3, and OW-1 were advanced into soil which was composed primarily of topsoil followed by saprolite. A black-to-grey fractured granodiorite was encountered in OW-1 at a depth of approximately 35 ft-bgs. However, bedrock was interspersed with saprolite in this location. There were no PID readings or other indications of impacted media in these locations. Soil samples were collected from the 0 to 2 ft-bgs depth interval from borings SB-1, SB-2, and SB-3. A soil sample was not collected from OW-1. Soil samples were collected in laboratory-provided containers, placed in a cooler on ice, and delivered to a Prism Laboratories, North Carolina-certified laboratory. Soil samples were analyzed for VOCs by United States Environmental Protection Agency (EPA) Method 8260, SVOCs by EPA Method 8270, Resource Conservation and Recovery Act (RCRA) metals using EPA Method 6010 and 7471, polychlorinated biphenyls (PCBs) by EPA Method 8082, chlorinated pesticides by EPA Method 8081, herbicides by EPA Method 8151, and pH by Method 9045D. 2.3 Monitoring Well Installation Prior to monitoring well installation, Anchor QEA obtained a County of Mecklenburg Subsurface Investigation Permit for well installation. Permit number 70002395 was issued on November 21, 2016. Anchor QEA oversaw the installation of four monitoring wells, OW-1, OW-2S, OW-2D, and OW-3, on November 28 and 29, 2016. Wells OW-2S and OW-2D were installed as nested wells in the same borehole. Monitoring wells were installed using sonic drilling technology in order to prevent downward migration of contaminants during installation in the landfill area. Monitoring well OW-1 was installed to a depth of 57 ft-bgs in the southeast corner of the Site to evaluate groundwater conditions in the area near a neighboring residential development. Monitoring wells OW-2S and OW-2D were installed in the landfill area to evaluate groundwater conditions within and downgradient of the landfill. This area of the landfill is where S&ME reported the LCID thickness to be greatest. Well OW-2S was installed to a depth of 36 ft-bgs, the depth of the Brownfield Site Assessment 5 January 2017 base of LCID in this area, and screened within LCID material. Well OW-2D was installed below LCID material to a depth of 50 ft-bgs. Monitoring well OW-3 was also installed into LCID material at a terminal depth of 26 ft-bgs, the depth of the base of LCID in this area. The monitoring wells are composed of 2-inch nominal inside-diameter (ID) Schedule 40 polyvinyl chloride (PVC). A 10-foot-long 0.010-inch machine-slotted screen was installed in monitoring wells OW-2S, OW-2D, and OW-3. A 20-foot-long screen was used in monitoring well OW-1. A #2 filter sand filled the annular space between the well screen and the borehole from the base of the borehole to a depth of approximately 2 feet above the top of the well screen. Hydrated bentonite pellets filled the annular space from the sand pack to 2 feet above the sand pack. A bentonite-grout mixture filled the annular space from the bentonite seal to 2 ft-bgs and the wells were completed with locking stick-up well covers set in a concrete pad. 2.3.1 Well Development After installation, Anchor QEA developed each monitoring well using the surge-and-bail method and purged using a submersible Whale® pump. Monitoring well OW-3 was found to be dry. Monitoring wells OW-2S and OW-2D were developed both on November 29 and November 30, 2016, due to limited recharge in these wells. A total of approximately 5.5 gallons was purged from OW-2S and 5.5 gallons from OW-2D. Water remained turbid in these wells. Well OW-1 was developed on November 30, 2016. A total of approximately 15 to 20 gallons was purged from this well. Water was mostly clear at the end of development. 2.4 Monitoring Well Sampling Anchor QEA sampled monitoring wells using dedicated polyethylene bailers on December 7, 2016. Prior to purging, groundwater levels were measured in each well using a water-level meter. During purging, field parameters for pH, specific conductance, turbidity, dissolved oxygen, and temperature were recorded after each well volume was removed. A groundwater sample was collected from each well after at least three well volumes had been purged. Due to very low recharge, OW-2D was purged dry after only one well volume and was subsequently sampled. Sample OW-2S should be considered a landfill contact water sample as it was collected from perched water within landfill LCID. The samples were transferred to laboratory-provided sample containers and placed in a cooler on ice for delivery to the laboratory. Groundwater samples were analyzed by Prism Laboratories for VOCs using EPA Method 8260, SVOCs using EPA Method 8270, total and dissolved RCRA metals using Method 6010 and 7471, chlorinated pesticides by EPA Method 8081, and herbicides by EPA Method 8151. Brownfield Site Assessment 6 January 2017 The sample collected from well OW-2D was only analyzed for VOCs, SVOCs, and chlorinated pesticides, due to limited sample volume. 2.5 IDW Management SAEDACCO containerized all groundwater and soil investigative derived waste (IDW) in 55-gallon Department of Transportation (DOT)-approved drums. Following review of laboratory analytical data, and in accordance with the IDW disposal guidelines in the Inactive Hazardous Sites Program Guidelines for Assessment and Cleanup, dated October 2015, Anchor QEA spread soil and groundwater IDW on-site on January 19, 2017 in the vicinity of the sample location from which the IDW was generated. Brownfield Site Assessment 7 January 2017 3 Assessment Results A summary of soil and groundwater assessment results are described in the following sub-sections. Groundwater elevations are show on Table 1, soil analytical results on Table 2, and groundwater analytical results in Table 3. Laboratory analytical reports are included as Appendix C. 3.1 Soil Sampling Results Soil analytical results were compared to the PSRGs. None of the samples contained concentrations of PCBs or herbicides in excess of the laboratory reporting limits. Other than a low concentration of one pesticide in SB-3, pesticides were not detected in excess of the laboratory reporting limits in any other sample. Soil samples SB-1, SB-2, and SB-3, which were collected in shallow soil in areas outside of the landfill footprint, did not contain concentrations of VOCs (other than acetone, a common laboratory contaminant) or SVOCs in excess of the laboratory reporting limit. All three of these samples contained detectable concentrations of metals, however all concentrations were below the PSRGs. A low concentration of trans-chlordane (0.0042 milligrams per kilogram [mg/kg]) was detected in sample SB-3, but at concentration below the PSRG of 7.7 mg/kg. Soil samples OW-2 (5-8), OW-2 (15-20), and OW-3 (17-18), which were collected from LCID material in the landfill contained concentrations of various VOC, SVOC, and metals constituents. However, all detections were at concentrations below the PSRGs. Additionally, metals detections in LCID material were similar to detections in non-LCID material at the Site. Generally, detected constituents are consistent with results obtained during S&ME’s assessment (S&ME 2016). 3.2 Monitoring Well Gauging Results Depth to groundwater on December 7, 2016 ranged from approximately 48 ft-bgs in OW-2D to 47 ft-bgs in OW-1. Groundwater elevation was measured at 530.09 feet above mean sea level (ft-msl) in OW-2D and 536.49 ft-msl in OW-1. Perched water (LCID contact water) was measured in well OW-2S at a depth of approximately 32 ft-bgs and a thickness of 3.4 feet. Elevation of perched water in OW-2S was measured at 546.77 ft- msl. 3.3 Monitoring Well Sampling Results Groundwater analytical results were compared to the North Carolina Administrative Code (NCAC) 02L .0202 groundwater standards (2L standards). Brownfield Site Assessment 8 January 2017 Pesticides and herbicides were not detected in any sample above the laboratory reporting limit. Sample OW-1 did not contain VOCs or SVOCs in excess of the laboratory reporting limit. This sample did contain detections of various metals (both total and dissolved) in excess of the 2L standard. However, these concentrations are likely attributable to sample turbidity and/or naturally occurring concentrations of these constituents. Samples OW-2S (LCID contact water sample) and OW-2D both contained concentrations of tetrachloroethylene (PCE) in excess of the 2L standard of 0.7 micrograms per liter (µg/L). PCE was detected at a concentration of 1.2 µg/L in OW-2S and 3.8 µg/L in OW-2D. Additional VOCs in both of these samples and SVOCs in OW-2S were detected, but at concentrations below the 2L standards. Various metals (both total and dissolved) were detected in OW-2S at concentrations in excess of the 2L standards. The concentrations of metals in OW-2S are only slightly higher than the concentrations detected in OW-1, indicating that landfill LCID is likely not a significant contributor of metals to groundwater. Brownfield Site Assessment 9 January 2017 4 Receptor Survey A Brownfields Area Reconnaissance and Receptor Survey was performed on November 23, 2016 by Anchor QEA personnel. A Brownfields Area Reconnaissance and Receptor Survey Guidance Form is included in Appendix D and a Receptor Survey Map is included as Figure 4. Results of the receptor survey indicate that University Park Baptist Church, located to the south of the Site, and owned by Park Ministries Inc. (the Site owner), has an irrigation supply well and septic field. The well is approximately 600 feet to the south of the Site. According to Mr. Rick Galloway, Park Ministries Inc. representative, the church property is provided potable water through Carolina Water Utilities, Inc. Another church was identified approximately 500 feet to the west of the Site. Most of the surrounding area is supplied by municipal water and sewer services. However, the Danby Road development is supplied by four public water supply wells, located approximately 0.5 miles to the southwest of the Site. Additionally, a water supply well was identified on Darington Court, located approximately 1,500 feet to the southwest of the Site. However, Mecklenburg County Department of Groundwater and Wastewater Services data indicates that the Darington Court well is currently inactive. One possible, existing groundwater monitoring well was observed approximately 600 feet to the south of the Site. This well did not have a protective casing and it’s construction information is unknown. McAlpine Creek is located 500 feet to the north of the Site, in the likely downgradient direction of the on-site landfill. Based on Mecklenburg County hydrology, a pond may be located 500 feet to the southeast of the Site. Brownfield Site Assessment 10 January 2017 5 Conclusions The results of this assessment and previous assessment (S&ME 2016) indicate that the western portion of the Site was used as an inert debris landfill. LCID material primarily consists of soil, wood, with some asphalt and concrete. Historical topographic maps and field observations indicate that LCID was placed in a drainage swale or gully on the western side of the Site. Soil analytical results indicated that VOCs and SVOCs are present in LCID material, but at concentrations below the industrial/commercial PSRGs. Also, constituents of concern have not been detected in soil outside of the landfill footprint. Five feet of soil was observed covering LCID material in the OW-2 and OW-3 locations. Concentrations of PCE in groundwater within the landfill footprint slightly exceed the 2L standards. This data indicates that there may be an isolated source of PCE in landfill LCID upgradient of monitoring wells OW-2S and OW-2D. However, multiple soil samples, both during this assessment and S&ME’s assessment (S&ME 2016) have not located a source of PCE in soil or landfill LCID. Sensitive receptors were not identified in the likely downgradient direction of impacted- groundwater. However, an irrigation supply well was identified approximately 600 feet to the south of the Site, in the upgradient direction. An active public water supply well system was also identified approximately 0.5 miles to the southwest of the Site. Site topography and observations of landfill placement indicate that groundwater below the landfill likely flows to the north and northwest, eventually discharging to McAlpine Creek. Therefore, the irrigation supply well and water supply well system are not expected to be affected by impacted groundwater on-site.
