A Site location map is provided as Figure 1. The Site is comprised of an approximately 22-acre parcel that is vacant except for the foundations of the former Site buildings. Multiple companies occupied the Site beginning in the mid to late 1960s for textile operations including dyeing and finishing woven fabrics. Textile Piece Dyeing Co. of Delaware (TPDD) acquired the Site in 1993 and continued textile operations until 2013. The textile facility buildings were razed in 2015. Prior to TPDD operations at the Site, previous occupants utilized tetrachloroethene (PCE) in a textile-related scouring process. PCE impacts in Site groundwater were discovered in approximately 1993. In 1996, TPDD voluntarily implemented corrective action measures at the direction of the North Carolina Department of Environmental Quality (DEQ) to contain the PCE plume and remove contaminant mass from the underlying aquifer using a groundwater extraction system. Monitoring of groundwater conditions to evaluate the effectiveness of the groundwater extraction system continued at the Site until approximately 2010. The purpose of H&H’s activities was evaluate the potential for vapor intrusion to nearby off-Site structures from groundwater impacts associated with the Site. The activities were conducted in a phased approach that included the following steps: 1) review and evaluation of previous groundwater assessment data, 2) gauging and sampling of existing monitoring wells, 3) installation and sampling of deeper soil vapor probes near the Site boundaries where residences are located, and 4) installation of off-Site soil vapor probes near residences. The methods and results of our activities are presented in the following sections. 2 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc 2.0 Supplemental Assessment Activities 2.1 Groundwater Assessment Activities 2.1.1 Previous Groundwater Data Review To evaluate the potential for off-Site vapor migration, H&H initially reviewed data for existing monitor wells to 1) determine if there are wells screened across the water table that are suitable for evaluation of potential vapor intrusion, and 2) review the analytical data for those wells which are deemed suitable. Adjacent off-Site structures are located south-southeast and west- northwest of the Site as indicated in Figure 2. Based upon our review, two wells along the western and southern property boundaries met the criteria for shallow wells which monitor the water table (MW-1 and MW-3). MW-1 is located in the southwestern portion of the Site and has historically not contained concentrations of compounds. Previously measured depths to groundwater in MW-1 have been in the range of 25 to 30 ft below ground surface (bgs). MW-3 is located in the northwestern portion of the Site and both tetrachloroethene (PCE) and trichloroethene (TCE) have been detected in low concentrations in the well above the DEQ Division of Waste Management (DWM) Residential Vapor Intrusion Screening Levels (VISLs). In 2010, PCE was detected in MW-3 at 68 µg/l versus the VISL of 11.5 µg/l, and TCE was detected at 2.2 µg/l versus the VISL of 1.04 µg/l. Please note that the VISLs are very conservative and do not indicate that there is a vapor intrusion issue, only that further evaluation may be warranted. Previously measured depth to groundwater in MW-3 was in the range of 60 ft or greater, although the previously measured depths to water in MW-3 were likely impacted by the extraction wells which are no longer operating. Based upon the results of the initial data review, H&H performed Site assessment activities which included locating existing monitor wells, gauging of the wells to determine non-pumping groundwater flow direction, and collecting groundwater samples from MW-1 and MW-3 to determine current volatile organic compound (VOC) data for the shallow wells. The methods and results of the monitor well gauging and sampling data are provided in the following sections. 3 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc 2.1.2 Monitor Well Gauging On January 16, 2017, H&H and a private utility locator attempted to locate the Site groundwater monitoring wells utilizing historical Site maps, a metal detector, ground penetrating radar, and electromagnetic survey techniques. The locations of the Site monitoring wells are depicted on Figure 2. H&H located six Site groundwater monitoring wells (MW-1, MW-3, MW-8, MW-9, MW-10, and MW-14) and collected depth to groundwater measurements using a decontaminated electronic water level indicator from these wells. H&H utilized well construction records, previously surveyed top of well casing elevations data, and the January 16, 2017 depth to water measurements to calculate groundwater elevations. A summary of well construction details and groundwater elevations is provided as Table 1. Using the calculated groundwater elevations for the six measured monitor wells, H&H estimated the shallow aquifer groundwater flow direction across the Site. A groundwater hydraulic gradient map depicting the general groundwater flow at the Site is presented on Figure 3. As depicted on Figure 3, the groundwater flow direction across the Site is generally to the north toward Walker Branch. 2.1.3 Monitor Well Sampling To evaluate current VOC concentrations in shallow groundwater near the northwestern and southwestern property boundaries, H&H collected groundwater samples from monitoring wells MW-1 and MW-3. MW-1 is located topographically upgradient of the former textile facility in the southwestern portion of the Site (Figure 2). MW-3 is located topographically downgradient to cross-gradient of the former textile facility in the northwestern portion of the Site (Figure 2). During groundwater sampling activities, a calibrated water quality meter was used to collect measurements of field parameters including pH, temperature, dissolved oxygen, oxidation reduction potential, turbidity, and specific conductivity. Groundwater samples were collected from each well by removing groundwater in the wells until field parameters stabilized (pH ± 0.1 SU and conductivity varied no more than 5%). 4 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc The MW-1 groundwater sample was collected using low-flow/low stress purging techniques with a peristaltic pump and dedicated polyethylene tubing. The intake point of the tubing was placed in the approximate mid-portion of the well screen and groundwater was removed at a rate of approximately 200 milliliters per minute until field parameters stabilized. The groundwater sample was collected directly into laboratory supplied sample containers using the “soda straw” method to minimize volatile loss through the peristaltic pump head. Because depth to groundwater was greater 30 ft bgs (maximum head a peristaltic pump can remove groundwater), the MW-3 groundwater sample was collected using purge-by-volume sampling methods. A new, disposable polyethylene bailer was used to purge a minimum of three well bore volumes of standing water until field parameters stabilized (pH ± 0.1 SU and conductivity varied no more than 5%). After purging, the groundwater sample was collected directly into laboratory supplied sample containers directly from the bailer. Groundwater sampling forms are provided in Appendix A. The sample containers were labeled with sample identification, date, and requested analysis, placed in a laboratory supplied cooler with ice, and delivered to Pace Analytical of Huntersville, NC, a North Carolina certified laboratory under standard chain-of-custody protocols for analysis of VOCs by EPA Method 8260B. The chain-of-custody record and laboratory data sheets are provided in Appendix B. 2.1.4 Monitoring Well Sample Results Groundwater analytical results were compared to DEQ 15A NCAC 02L.0202 Groundwater Quality Standards (2L Standards) and the DEQ DWM Residential and Non-Residential Vapor Intrusion Groundwater Screening Levels (VIGWSLs) dated October 2016. A tabular summary of the analytical results for groundwater samples is provided in Table 2, and compound concentrations detected above the screening criteria are presented on Figure 4. 5 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc The laboratory analytical results indicate that no compound concentrations were detected above the laboratory reporting limits in the groundwater sample collected from monitoring well MW-1 (upgradient monitoring well). The results of analysis of the sample collected from MW-3 (cross-gradient to downgradient monitoring well) indicate that PCE (60.5 µg/L), trichloroethene (TCE) (2.0 µg/L), and cis-1,2- dichloroethene (2.2 µg/L) were detected above the laboratory reporting limits. Of the compounds detected, the PCE detection exceeds the 2L Standard of 0.7 µg/L and the DWM Residential and Non-Residential VIGWSLs of 11.5 µg/L and 48.4 µg/L, respectively. Additionally, the TCE detection exceeds the Residential VIGWSL of 1.04 µg/L, but not the 2L Standard of 3.0 µg/L or the Non-Residential GWSL of 4.35 µg/L. 2.2 On-Site Soil Vapor Assessment Activities 2.2.1 On-Site Soil Vapor Monitoring Probe Installation and Sampling Concurrent with the groundwater sampling activities, H&H also collected on-Site soil vapor samples from the northwestern and southern portions of the Site. On January 17, 2017, Innovative Environmental Technologies, Inc. (IET) utilized a decontaminated stainless-steel hand auger and a Power Probe VTR direct push technology (DPT) drill rig to advance soil borings for installation of five permanent vapor monitoring points (VMP-1 through VMP-5) on the subject Site. One soil vapor monitoring probe (VMP) was installed along the southern Site boundary near the closest residence south of the Site (VMP-1) and four VMPs were installed along the western and northwestern Site boundary (VMP-2 through VMP-5) between the former Site building and off-Site residences to the west and northwest. The locations of the soil vapor monitoring points are depicted on Figure 2. During boring advancement, continuous soil samples were collected from the borings using a macro-core sampler lined with acetate sleeves. Soil samples were described for lithologic purposes and inspected for obvious indication of staining and unusual odors, and field screened for elevated volatile organic vapors using a calibrated photoionization detector (PID). Boring 6 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc logs with lithologic descriptions and VMP construction details are included in Appendix C. The VMPs were installed as permanent sampling points. Each VMP soil boring was advanced to approximately 15 ft bgs and was constructed by placing a stainless steel gas vapor probe tip fitted with ¼-inch diameter Teflon® tubing (extending above the ground surface) approximately three inches above the bottom of each boring. A filter sand pack was then placed from the bottom of the boring to approximately six inches above the vapor probe tip. An approximately 10 ft hydrated bentonite seal was placed on top of the sand pack and the boring was completed with grout to the surface. The sample tubing was capped with a petcock valve and a protective housing with a steel manhole cover was installed around the sample tubing at the top of the boring and secured within a 2 ft by 2 ft concrete pad. Prior to sampling, a leak check was conducted at each VMP by constructing a shroud around the sampling point and flooding the air within the shroud with helium gas. Using a syringe, a sample was collected from the gas in the shroud into a Tedlar® bag and analyzed for helium concentrations using a helium gas detector. Then, vapor from the VMP was purged and sampled outside of the shroud into a separate Tedlar® bag and analyzed using the helium gas detector. At each VMP, the helium concentrations in the Tedlar® bag was less than 10% of the helium concentrations detected in the shroud. Copies of the successful leak check forms are included as Appendix D. On January 18, 2017, after a successful leak check, an above-ground sampling system was constructed at each VMP on to facilitate sampling. Each system was constructed as follows: • A sampling manifold was connected to the VMP tubing. The manifold included a ferrule fitting for air-tight connection to the tubing, followed by a vacuum gauge separated by a flow regulator (calibrated to allow a flow of less than or equal to 200 ml/min). • A laboratory-supplied passivated stainless steel sample canister was connected to the flow regulator. Prior to connecting the sample canister to the manifold, vacuum in the canister was measured using a laboratory-supplied vacuum gauge and recorded by sampling 7 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc personnel. • Each sample was collected into a 6-liter Summa canister over a period of approximately 1 hour. During sample collection, vacuum measured in the sample line was periodically observed and recorded and sample collection was stopped when vacuum reached approximately 5 inches mercury. After completion of sampling, each sample canister was disconnected from the sample system and final vacuum in the canister was measured using a laboratory-supplied vacuum gauge and recorded by sampling personnel. The starting and ending vacuum in each canister was recorded on the chain-of-custody and submitted to Con-Test Analytical Laboratories (Con-Test) along with the samples. The sample canisters were labeled and shipped under standard chain-of-custody protocols Con-Test for analysis of VOCs by EPA Method TO-15. The chain-of-custody record and the laboratory data sheets are provided in Appendix B. Upon completion of sampling activities, the sample locations were estimated using a hand-held global positioning system (GPS) unit. 2.2.2 On-Site Soil Vapor Assessment Results Soil vapor analytical results were compared to the DEQ DWM Residential and Non-Residential Vapor Intrusion Soil Gas Screening Levels (SGSLs) dated October 2016. A tabular summary of on-Site soil vapor analytical results is presented in Table 3, and concentrations of compounds detected above the screening criteria are depicted on Figure 5. Laboratory analytical results indicate that several compounds were detected above the laboratory reporting limits in all five samples. No compound concentrations were detected above the SGSLs in vapor monitoring point VMP-1 collected in the southern portion of the Site which is consistent with the lack of groundwater impacts in monitor well MW-1. Based upon the groundwater flow direction and groundwater and soil vapor analytical data, groundwater impacts at the Site do not pose a significant risk for residences located south of the Site. 8 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc In the samples collected along the western and northwestern Site boundaries, PCE was detected above the Residential SGSL of 278 µg/m3 in VMP-2 (3,300 µg/m3), VMP-3 (6,100 µg/m3), VMP- 4 (750 µg/m3), and VMP-5 (2,600 µg/m3). The PCE detection in VMP-3 also exceeds the Non- Residential SGSL of 3,500 µg/m3. In addition to PCE, chloroform was detected in VMP-5 (1,200 µg/m3) at a concentration exceeding the Residential SGSL of 40.7 µg/m3 and the Non-Residential SGSL of 533 µg/m3. Chloroform was not detected in any other soil vapor sample at a concentration exceeding the SGSLs. No other compounds were detected in any other soil vapor sample at concentrations exceeding the SGSLs. Based upon the results of the on-Site soil vapor assessment, H&H performed soil vapor assessment at off-Site residences located west and northwest of the Site. The methods and results of the off-Site soil vapor assessment are presented below. 2.3 Off-Site Vapor Assessment Activities 2.3.1 Off-Site Soil Vapor Monitoring Probe Installation and Sampling The closest residences to the western Site boundary are located approximately 200 ft to 300 ft from the Site boundary on the other side of a topographic valley and intermittent unnamed tributary of Walker Branch. Although topography and the unnamed tributary likely act as a hydraulic divide for potential migration of groundwater impacts, H&H conducted assessment activities near these structures to evaluate the potential for vapor intrusion. Prior to the sampling, TPDD obtained access agreements from four adjacent property owners to install temporary soil vapor monitoring points (TVMPs) at 911 Danbrook Circle (TVMP-1), 913 Danbrook Circle (TVMP-2), 915 Danbrook Circle (TVMP-3), and 919 Danbrook Circle (TVMP-4). The locations of the off-Site TVMPs are shown on Figure 2. On May 8, 2017, H&H advanced soil borings on the eastern side of each of the residences utilizing a decontaminated stainless steel hand auger. As each boring was advanced, continuous samples were collected from the center of the hand auger bucket. Soil samples were described for lithologic 9 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc purposes, inspected for the presence of obvious staining and unusual odors, and field screened for elevated volatile organic vapors using a calibrated PID. Boring logs with lithologic descriptions and TVMP construction details are included in Appendix C. Each TVMP boring was advanced to approximately 6 ft bgs and then constructed by placing a stainless steel gas vapor probe tip fitted with ¼-inch diameter Teflon® tubing (extending above the ground surface) at the bottom of each boring. A filter sand pack was then placed from the bottom of the boring to approximately six inches above the vapor probe tip and a hydrated bentonite seal was placed from the top of the sand pack to the ground surface. The sample tubing was capped with a petcock valve and left temporarily in place for sampling the following day. On May 9, 2017, H&H returned to the Site to sample the four off-Site TVMPs. Prior to sampling, a leak check was performed at each TVMP using methods outlined for the on-Site soil vapor probes discussed above in Section 2.2. Copies of the successful leak check forms are included as Appendix D. After a successful leak check, an above ground sampling system was constructed at each TVMP using the same methodology as described in Section 2.2 above. The samples were collected into laboratory supplied 6-liter Summa canisters over a period of approximately 1 hour. During sample collection, vacuum measured in the sample line was periodically observed and recorded and sample collection was stopped when vacuum reached approximately 5 inches mercury. After completion of sampling, each sample canister was disconnected from the sample system and final vacuum in the canister was measured using a laboratory-supplied vacuum gauge and recorded by sampling personnel. The starting and ending vacuum in each canister was recorded on the chain-of-custody and submitted to Con-Test along with the samples. The sample canisters were labeled and shipped under standard chain-of-custody protocols for analysis of VOCs by EPA Method TO-15. The chain-of-custody record and laboratory analytical data sheets are provided in Appendix B. After all samples were collected, each TVMP was deconstructed, ground conditions were restored to pre-installation conditions, and the sample locations were estimated using a hand-held GPS unit. 10 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc 2.3.2 Off-Site Soil Vapor Assessment Results The laboratory analytical results for the off-Site soil vapor samples were compared to the DWM Residential Vapor SGSLs. A summary of the laboratory analytical data is provided as Table 4. Laboratory analytical results indicate that several compounds were detected above the laboratory reporting limits in each of the off-Site soil vapor samples. However, no compounds concentrations exceed the Residential SGSLs in any of the samples. As such, groundwater impacts at the Site do not pose a significant risk for vapor intrusion to off-Site residences located west and northwest of the Site. 11 S:\AAA-Master Projects\Textile Piece Dyeing\VI Eval\Supplemental Assessment Report\Final To Client\Textile Piece Dyeing_Supplemental Assessment Report_20170706.doc 3.0 Summary and Conclusions H&H has completed supplemental assessment activities at the former Textile Piece Dyeing facility located in Lincolnton, North Carolina to evaluate the potential for vapor intrusion to nearby off-Site structures from groundwater impacts associated with the Site. Based upon the results of our activities, H&H makes the following conclusions: • Groundwater flow direction at the Site is to the north toward Walker Branch. • No compounds were detected above laboratory reporting limits in the upgradient groundwater sample collected in the southwestern portion of the Site (MW-1). In addition, no compound concentrations were detected above Residential SGSLs in a soil vapor sample collected in the southern portion of the Site near residences located south of the Site. As such, there is no completed exposure pathway for vapor intrusion for residences located south of the Site. • PCE and TCE were detected above the DEQ Vapor Intrusion GWSLs in the downgradient groundwater sample collected in the northwestern portion of the Site, and PCE and/or chloroform were detected above the DWM Residential Vapor Intrusion SGSL in all four soil vapor samples collected along the western and northwestern Site boundary (VMP-2 through VMP-5). Results of soil vapor sampling near adjacent residences located approximately 200 ft to 300 ft west and northwest of the Site boundary and on the other side of an intermittent stream indicated that no compounds were detected above the DWM Vapor Intrusion SGSLs. As such, there is no completed exposure pathway for vapor intrusion for residences located west and northwest of the Site. Based upon the results of our activities, H&H concludes that vapor intrusion is not a complete exposure pathway for off-Site structures. Therefore, H&H does believe that further assessment of the off-Site vapor intrusion pathway is warranted.
