A Site Location Map is provided as Figure 1. H&H recently completed a Phase I Environmental Site Assessment (ESA) on the Site and identified the following recognized environmental condition (REC): • The facility was previously used for textile knitting and dyeing from the early 1970s to late 1990s. A lined wastewater lagoon was constructed in the early 1990s in the southeastern portion of the Site. The wastewater lagoon reportedly received wastewater from dyeing operations, which was allowed to cool in the lagoon prior to discharge to the municipal sanitary sewer. The lagoon also reportedly received fluids from the floor drains located throughout the Site. There are two existing groundwater BB&T Environmental Risk Management January 27, 2017 Page 2 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc monitoring wells located south and topographically downgradient of the wastewater lagoon. H&H was not provided information about the purpose of the wells or data for the wells. In addition, groundwater samples collected on the adjacent property to the south in 1992 indicated the presence of the metals chromium, lead, and beryllium above North Carolina groundwater standards. The report of that sampling indicated that the presence of metals may be associated with naturally occurring metals or potentially with several nearby textile facilities, including the subject Site. H&H considered the potential for soil and/or groundwater impact from historical textile knitting and dyeing operations, including the wastewater lagoon, to be a REC. H&H conducted Phase II ESA activities on January 13, 2017 to evaluate the potential for impact to the Site from historic textile knitting and dyeing operations. The assessment activities included advancing four soil borings, collecting soil samples from the four borings for laboratory analysis, converting one of the borings into a temporary monitoring well, installing one additional temporary monitoring well, and sampling the temporary monitoring wells and two existing monitoring wells for laboratory analysis. The results of analysis of the soil samples indicated that no volatile organic compounds (VOCs) were detected and metals concentrations in the potential areas of concern are consistent with Site-specific and published regional background levels. Results of analysis of the groundwater samples indicated that the VOC chloroform was detected in existing monitoring well MW-2 at a concentration of 2.6 µg/L, which is well below the North Carolina groundwater standard of 70 µg/L. No other VOCs were detected in any of the groundwater samples. The results of the metals analysis indicate that metals concentrations are consistent with Site-specific background levels, with the exception of an elevated manganese detection in existing monitoring well MW-2 (1,600 µg/L) which is located south and topographically downgradient of the wastewater lagoon. The elevated manganese detection in MW-2 exceeds both the North Carolina groundwater standard of 50 µg/L and the Site-specific BB&T Environmental Risk Management January 27, 2017 Page 3 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc background concentration of 390 µg/L. Turbidity of the sample from MW-2 was less than 10 NTU indicating that the elevated level of manganese is not likely associated with suspended sediment in the sample. However, the pH of the MW-2 sample and adjacent well MW-1 (also located downgradient of the lagoon) were low and in the range of 4.5 versus the background level of 5.5 and the level downgradient of the building of 5.8. In addition, dissolved oxygen concentrations were lower in groundwater in MW-1 and MW-2 as compared to the other Site wells. The presence of lower pH and lower dissolved oxygen concentrations can lead to mobilization of naturally occurring manganese in aquifer sediment. Although the source of the manganese is not conclusively known, it is possible that acidic wastewater discharged to the lagoon may have created low pH and low dissolved oxygen conditions which mobilized naturally occurring manganese in the aquifer. It is also possible that naturally occurring low pH conditions may be present in this area of Site. 2.0 Property Description & Background The Site consists of one parcel that is 9.48 acres in area and is developed with a one-story to three-story manufacturing and warehouse building totaling approximately 140,000 sq ft, a portion of which is leased as warehouse space. The majority of the Site building is one story; lower levels are present in the western and the southeastern portions of the Site building, and an elevated former dye storage room is present in the southeastern portion of the Site building. The remainder of the Site contains asphalt paved parking areas, concrete sidewalks, a wastewater lagoon, and landscaped areas. The Site was used for residential purposes from prior to 1938 until the mid-1960s to early 1970s. Portions of the current Site building were constructed in approximately 1972 and were occupied by various textile manufacturers (Adventure Knits, James River Knits, Modern Globe, RP Sportswear, Bassett-Walker, and Spring Ford Knitting) until the late 1990s. Since 2003, the Site has been owned by the current owner Benmar Properties, LLC. Since the late 1990s, the Site BB&T Environmental Risk Management January 27, 2017 Page 4 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc building has been leased for warehousing purposes. A Site Location Map is provided as Figure 1, and a Site Map is provided as Figure 2. 3.0 Phase II Scope of Work 3.1 Utility Clearance Prior to conducting soil and groundwater sampling activities, H&H contacted North Carolina One-Call, the state public utility locator to mark subsurface utilities located on the Site. In addition, Sweetwater Utility Locating (Sweetwater) of Statesville, North Carolina, a private utility locater, was contracted to locate and demark subsurface utilities in the area of the soil borings and temporary well. As an additional safety precaution, each boring was initially advanced using a hand auger to a depth of five feet below ground surface (bgs) to clear the boring of possible undocumented subsurface utility lines. 3.2 Sampling Activities The Phase II ESA was conducted on January 13, 2017 and included the collection of soil and groundwater samples at the Site. The methods and results of the assessment activities are provided below. Soil Sampling H&H utilized Carolina Soil Investigations (CSI) of Olin, North Carolina to advance four soil borings using a Geoprobe® direct-push technology (DPT) drill rig and hand auger methods. During boring advancement, soil samples were field screened for the presence of odor, staining, and elevated photoionization detector (PID) readings. Soil boring logs are included in Appendix A. A summary of soil sample locations and analyses is presented below. BB&T Environmental Risk Management January 27, 2017 Page 5 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc • SB-1 and SB-2 were advanced within close proximity (2-3 ft) of the effluent side of the trench drains located in the eastern portion of the Site building to depths of approximately 5 ft below ground surface (bgs). Based upon low PID readings (<1.0 ppm) and lack of evidence of impacts, soil samples were collected from the estimated depth of the base of effluent piping and submitted for laboratory analysis of volatile organic compounds (VOCs) by EPA Method 8260 and Hazardous Substance List (HSL) metals plus hexavalent chromium by EPA Methods 6020/7471/7196. • SB-3 was advanced in the southeastern portion of the Site building beneath the former dye storage area, downgradient of an aboveground storage tank (AST) containment basin, and near the effluent side of a trench drain. No obvious evidence of impact or elevated PID readings was observed in the collected soil samples from the boring. Therefore, H&H collected a soil sample from the estimated depth of the base of effluent piping for laboratory analysis of VOCs by EPA Method 8260 and HSL metals plus hexavalent chromium by EPA Methods 6020/7471/7196. • A background soil boring (BK-1) was advanced in the northern portion of the Site in an area that does not appear to have impacted by historical operations to evaluate Site- specific background concentrations of naturally occurring metals in soil for comparison to those detected in soil borings SB-1 through SB-3. A composite soil sample was collected from the 4 to 6 ft bgs interval and submitted for laboratory of HSL metals plus hexavalent chromium by EPA Methods 6020/7471/7196. Soil samples were collected into laboratory-supplied containers, which were then sealed, labeled, placed into a laboratory-supplied sample cooler, and covered with ice. The cooler was shipped under standard chain-of-custody protocol to Con-Test Analytical Laboratory (Con-Test), a North Carolina-certified analytical laboratory. BB&T Environmental Risk Management January 27, 2017 Page 6 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc Groundwater Sampling Under the direction of H&H, two temporary monitoring wells (TW-1 and BK-1) were installed by CSI using a Geoprobe® DPT drill rig and hand auger methods. Subsequent groundwater samples were collected and submitted for laboratory analysis from the two temporary monitoring wells and from the two existing permanent monitoring wells. The locations and sample analyses are summarized as follows: Monitoring Well and Groundwater Analyses Area of Concern / Proposed Sample Location Well ID Total Boring Depth (ft) VOCs by EPA Method 8260 HSL Metals by EPA Methods 6020/7471 Downgradient of the former mill building TW-1 40 X X Background BK-1 45 X Downgradient of the wastewater lagoon (existing wells) MW-1 & MW-2 -- X X Notes: VOC = Volatile Organic Compounds HSL = Hazardous Substance List -- = Not Applicable TW-1 and BK-1 were constructed with 10 ft of one-inch diameter machine slotted PVC screen set to bracket the water table and 30 to 35 ft of one-inch diameter well riser. Filter sand was placed in the annulus space between the borehole and the well screen to approximately two ft above the screen interval. A two ft hydrated bentonite seal was then placed on top of the filter sand. H&H measured the static depth to groundwater relative to the top of casing elevation in both the temporary and existing permanent monitoring wells. For reference, the existing wells were designated as wells MW-1 and MW-2 as shown in Figure 2. The depth-to-water (DTW) measurements in the wells ranged from approximately 27 ft bgs in MW-2 to 41 ft bgs in BK-1. BB&T Environmental Risk Management January 27, 2017 Page 7 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc The monitoring wells were developed by purging a minimum of three well volumes. After a minimum of three well volumes were purged, development was considered complete when field parameters of temperature, pH, conductivity, oxidation reduction potential (ORP) stabilized, and turbidity was less than or near 10 NTU. Following well purging, groundwater samples were collected utilizing laboratory-supplied containers. The containers were then sealed, labeled, placed into laboratory-supplied sample coolers, and covered with ice. The coolers were shipped under standard chain-of-custody protocols to Con-Test. The groundwater samples were submitted for analysis of VOCs by EPA Method 8260 (except BK-1) and HSL metals by EPA Methods 6020/7471. 3.3 Boring Abandonment and Investigation Derived Waste Upon completion of the soil and groundwater sampling activities, H&H directed CSI to abandon the temporary monitoring wells and soil borings by removing well screen materials, filling the soil borings with hydrated bentonite and/or grout, and patching the surfaces to match the surrounding area. Because no evidence of significant impacts were observed, soil cuttings and groundwater generated during soil and groundwater assessment activities were spread on-site in accordance with North Carolina Department of Environmental Quality (DEQ) guidance. 3.4 QA/QC Process H&H utilized standard quality assurance/quality control (QA/QC) processes during the Phase II ESA activities. Non-dedicated sampling equipment, including DPT tooling, the water level meter, and the hand auger, were decontaminated using Liquinox® detergent and deionized water prior to and between each sampling location. H&H and CSI wore nitrile gloves while handling samples, and the groundwater samples were collected using a dedicated bailer or tubing. Soil and groundwater samples were collected in laboratory-provided containers and placed on ice immediately after collection. A completed chain-of-custody (COC) record accompanied the BB&T Environmental Risk Management January 27, 2017 Page 8 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc samples and included the sample designation, date and time collected, matrix, sample container information, and requested analyses. 4.0 Site-Specific Topography, Geology, & Hydrogeology 4.1 Topography The elevation of the Site is between approximately 780 and 800 feet above mean sea level. The northeastern Site boundary is on a topographic high. An intermittent tributary of Duharts Creek is located along the western and southern Site boundaries. Duharts Creek is located approximately 750 ft southeast of the Site. An area topographic map is included as Figure 1. 4.2 Geology and Hydrogeology Regional Geology and Hydrogeology The Gastonia area, including the Site, is located in the Piedmont Physiographic Province of North Carolina. The Piedmont region consists of low, rounded hills and long, rolling, northeast- southwest trending ridges. The region is underlain by rock types that are primarily metamorphosed quartz diorite. In the Piedmont, the crystalline bedrock is overlain by a mantle of weathered rock termed saprolite or residuum. The saprolite consists of unconsolidated clay, silt, and sand with lesser amounts of rock fragments. Due to the range of parent rock types and their variable susceptibility to weathering, the saprolite ranges widely in color, texture, and thickness. Generally, the saprolite is thickest near interstream divides and thins toward stream beds. In profile, the saprolite normally grades from clayey soils near the land surface to highly weathered rock above competent bedrock. BB&T Environmental Risk Management January 27, 2017 Page 9 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc The occurrence and movement of groundwater in the Piedmont is typically within two separate but interconnected water-bearing zones. A shallow water-bearing zone occurs within the saprolite, and a deeper water-bearing zone occurs within the underlying bedrock. Groundwater in the shallow saprolite zone occurs in the interstitial pore spaces between the grains comprising the saprolite soils. Groundwater in this zone is typically under water table or unconfined conditions. In general, groundwater migrates laterally from recharge areas to small streams that serve as localized discharge points. The occurrence and movement of groundwater in the underlying water-bearing zone within the crystalline bedrock is controlled by secondary joints, fractures, faults, and dikes within the bedrock. On a regional scale, the direction of groundwater flow is typically from uplands to major streams and groundwater sinks. The saprolite has a higher porosity than the bedrock and serves as a reservoir that supplies water to a network of fractures in the bedrock. Site Geology and Hydrogeology The shallow soil at Site consists primarily of silts and clays to the maximum depth of sampling of approximately 45 ft bgs. Bedrock was not encountered during drilling activities. Depth to groundwater at the Site ranged from approximately 41 ft bgs in the northern portion of the Site to approximately 27 ft bgs in the southeastern portion of the Site. 5.0 Analytical Laboratory Results The results of analyses of the soil samples are summarized in Table 1, the results of analyses of the groundwater samples are summarized in Table 2, and the groundwater field measurements are summarized in Table 3. Laboratory analytical data reports and chain-of-custody records are included as Appendix B. BB&T Environmental Risk Management January 27, 2017 Page 10 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc Soil Laboratory analytical results indicate VOCs were not detected in any of the soil samples at concentrations exceeding laboratory reporting limits. The results of the metals analysis indicate that the metals arsenic (in SB-1), manganese (in SB-3), and thallium (in SB-1 and SB-3) and were detected slightly above the Site-specific background concentration and above DEQ Preliminary Soil Remediation Goals (PSRGs). However, the detected metals concentrations are within the range of published regional background levels for North Carolina soil. Given that only one Site-specific background sample was collected, metals concentrations are within the range of typical regional background levels, and our experience, the detected arsenic, manganese, and thallium concentrations appear to be naturally occurring. Groundwater Results of analysis of the groundwater samples indicate that the VOC chloroform was detected in existing monitoring well MW-2 at a concentration of 2.6 µg/L, which is well below the North Carolina groundwater standard of 70 µg/L. No other VOCs were detected in any of the groundwater samples at concentrations exceeding laboratory reporting limits. The results of the metals analysis of the groundwater samples indicate that metals concentrations are consistent with Site-specific background levels and below the North Carolina groundwater standards except for manganese in well MW-2. MW-2 is located downgradient and south of the former wastewater lagoon. Manganese was detected in background well BK-1 at a concentration of 390 µg/L. Manganese was detected in temporary well TW-1 at a concentration of 310 µg/L, and in the existing monitoring wells MW-1 and MW-2 at concentrations of 340 µg/L and 1,600 µg/L, respectively. The manganese detections in TW-1 and MW-1 are above the North Carolina groundwater standard of 50 µg/L, but are below the Site-specific background concentration of 390 µg/L. The manganese detection in MW-2 exceeds both the North Carolina groundwater standard of 50 µg/L and the Site-specific background concentration of 390 µg/L. As indicated in BB&T Environmental Risk Management January 27, 2017 Page 11 S:\AAA-Master Projects\BB&T\BBT-289 Old Well B2 LLC Ph II ESA (OMS-226731-R1)\Report\Phase II ESA_BBT-289.doc Tables 2 and 3, turbidity was low in all of the groundwater samples including MW-2 (turbidity of 2.03 NTU); therefore, it is unlikely that the elevated manganese concentration in MW-2 is associated with suspended sediment in the sample. As discussed in Section 3.2 above, field measurements of temperature, pH, conductivity and ORP were collected during the groundwater sampling event. A review of the field parameters indicates that pH in well MW-2 and adjacent well MW-1 located south of the lagoon were in the range of 4.5 to 4.6 and lower than the pH measured in background well BK-1 (5.5) and the well downgradient of the building TW-1 (5.8). In addition, dissolved oxygen levels in MW-1 and MW-2 (0.75 mg/L to 1.75 mg/L) were lower than those measured in BK-1 (5.23 mg/L) and TW- 1 (4.33 mg/L). Manganese solubility increases under acidic (low pH) and low dissolved oxygen conditions. Although the source of the manganese is not conclusively known, it is possible that acidic and other wastewater discharged to the lagoon may have created low pH and low dissolved oxygen conditions which mobilized naturally occurring manganese in the aquifer near the lagoon. It is also possible that naturally occurring low pH conditions and low dissolved oxygen conditions may be present in this area of Site which have resulted in elevated manganese concentrations. 6.0 Findings H&H conducted Phase II ESA activities at the Site to assess the potential for impact from historic textile knitting and dyeing operations, including the wastewater lagoon. The results of the assessment activities indicate the following: • No significant soil impacts were identified in the potential areas of concern at the Site. • No VOCs were detected in any of the groundwater samples at concentrations exceeding North Carolina groundwater standards.
