Groundwater Sampling Report Former Stevcoknit Fabrics Company — Carter Plant 615 Wilmington Road Wallace, North Carolina NONCD0002543 I. INTRODUCTION, SITE DESCRIPTION, &HISTORY On January 6, 2000, a Comprehensive Site Assessment (CSA) was submitted by Solutions IES, Inc. to delineate chlorinated solvent and hydrocarbon contamination in the soil and groundwater at the above referenced site for property owner Delta Group, LLC. Review of the CSA by the NCDENR—Division of Water Quality (DWQ) generated a request by DWQ (February 4, 2004) for two additional monitoring wells at the leading edge of the chlorinated solvent contaminant plume to be sampled in order to obtain baseline groundwater quality. This work was completed and sampling results and conclusions submitted to the Division in the June 2004 Monitoring Well Installation and Sampling Report. After review of the report, the Division requested at least two additional monitoring wells (a shallow well and one below the upper confining layer) in the area of former temporary monitoring well S-15 located inside the plant and near the chemical unloading rack. This report provides results of this additional assessment work plus results of additional sampling of existing monitoring well(s). The Stevcoknit Fabrics Company —Carter Plant (see Figure l: Site Location Map) was originally part of the Carter Fabrics Division of J.P. Stevens & Co., Inc. The original Carter Fabrics Plant was built in Greensboro, NC in 1937. Carter Fabrics and J.P. Stevens & Co. Inc. merged in 1946 and the plant and business eventually sold to J.P. Stevens & Co., Inc. in the 1960s. J.P. Stevens operated the plant until 1986 at which time it was sold to Stevcoknit Fabrics Company, a subsidiary of Delta Mills, Inc. which was owned and operated by Delta Woodside Industries, Inc. Stevcoknit Fabrics Company did not use PCE, however, the sister plant in Greensboro, and likely the Carter Plant in Wallace, did use PCE for a wool fabric program for approximately three years in the early 1970s. The site of the former Greensboro Carter Fabrics plant has an ongoing subsurface investigation for PCE contamination in groundwater (GW Incident #16104). The Carter Plant in Wallace is part of an approximately 92 acre site that includes the Holly Plant which was built by J.P. Stevens & Co., Inc. in the euly 1970s (see Figure 3). Both plants dyed and finished fabric until the Holly Plant was converted to a knitting operation and the plants connected in 1993. The site also includes a formerly abandoned 750,000—gpd wastewater contact stabilization plant and 5.0 MGD wastewater treatment plant. The chemical unloading dock that is the likely source area for PCE contamination includes a loading rack for an indoor tank farm that was removed in calendar year (CY) 2001. Petroleum hydrocarbon contamination in soil and groundwater at the site is the result of other releases which are not related to the chemical unloading rack. IL GROUNDWATER SAMPLING ACTIVITIES Groundwater sampling was conducted on October 20 and 21, 2015 by B&G Enviromnental Technician Steven Genald. Initially all wells were located, opened and allowed to equilibrate to atmospheric pressure. Monitoring well MW-6 was found with the steel cover damaged and unsecured lying loosely on top of the well. The well cap was also found to be damaged and soil was observed falling into the well casing. The well cap and lock were replaced, but the cover was not able to be repaired. Water level measurements were obtained for each well using an elech•onic water level probe. The water level probe from each well was cleaned and decontaminated after each measurement. Water levels were again determined after approximately 15-30 minutes to ensure that the water levels had equilibrated in accordance with Standard Procedures (see Appendix 3). All monitoring wells, with the exception of previously abandoned MW-4, were sampled using the Standard Procedures in Appendix 3 for analysis by EPA Method 8260B for volatile organic compounds. Analytical results ar•e included in Appendix 1 and Field Sampling Data Forms are in included Appendix 2. All samples were packed on ice at the site and transported by chain —of — custody protocol to an EPA Drinldng Water Certified Laboratory for analysis. In addition, the pH, conductivity, and temperature of each sample were determined and recorded at the time of sampling (Appendix 2). III. SITE AND AREA CONDITIONS All monitoring wells were surveyed by ms consultants, inc. Locations of the wells, top of casing elevations, and groundwater elevations were placed on a groundwater contour survey (Figure 2). A groundwater contour map, developed from the elevation data, is also presented on Figure 2. IV. SAMPLING RESULTS Groundwater elevations measured during this sampling event are included in fable 1 (Figure 2) and monitoring well analytical results are summarised in Table 2. All laboratory analytical reports are included in Appendix 1. A. The groundwater sample fiom MW-8 (a few yards south of the source area) contained PCE, TCE and several degradation products at concentrations exceeding 2L Standards. B. The gromldwater sample from MW-2 (a few yards northeast of the source area) contained PCE and TCE above 2L Standards. Degradation products were present below 2L Standards. C. The groundwater samples from MW-10 and MW-3 no longer revealed contamination above 2L Standards. The samples obtained November 1, 2006 had PCE above the 2L Standard in both monitoring wells and TCE above the 2L Standard in MW-3. D. pH levels in wells MW-2, 3, 8, 11 and 12 were below the 2L Standard minimum of 6.5. 2 V. CONCLUSIONS A. The contaminant plume due to the PCE release is not moving horizontally along the shallow aquifer above the shallow clay Tense. B. Any plume migration that has occtured has been over a time period exceeding thirty years, as PCE was used at the site only for wool processing for approximately tluee years in the early 1970s. C. Soils beneath the building floor, the primary source area, are likely impacted due to leaching through the sump at the former chemical unloading station. D. Vertical and horizontal migration of contaminants by infilhation and percolation is limited by paved surfaces which include the building, former chemical unloading dock, fuel oil tank containment area, former supply room loading dock area, and the access roads. E. Review of the sampling results indicate that natural attenuation via au anaerobic pathway is occurring in the subsurface at the site due to detection of daughter products from PCE degradation. PCE degradation and intermediate compounds were detected in MW-2, MW-3, MW-8 and MW-11. F. Review of sampling results indicate concentrations of PCE and degradation products Cis-1-2—Dichloroethene and PCE intermediate trans—1,2—Dichloropropane have both decreased in the shallow monitoring wells (MW-2, MW-3, MW-8 and MW-11). VI. RECOMMENDATIONS A. Damaged areas in the former chemical unloading dock should be repaired. Cracks should be cleaned and filled with a ductile, two—part epoxy filler or similar. B. The sump for the former chemical unloading dock should be cleaned out, inspected, and modifications made to ensure it is impervious. C. All monitoring wells should be sampled annually. 3 TABLES r� �- Bensinger & Garrison Environmental, Inc. �'': TABLE 1: MONITORING WELL ELEVATIONS - OCTOBER 20, 2015 FORMER STEVCOI{NI I FABRICS COMPANY -CARTER PLANT WALLACE, NORTH CAROLINA Monitoring Well Total Depth (feet bgs) Screened Interval (feet bgs) Depth to Groundwater (feet TOC) Top of Casing Elevation BM 100') Groundwater Elevation (BM 1001) MW-1 21.5 16.5 - 21.5 7.25 100.15 92.90 MW-2 12.0 7.0 -12.0 6.95 100.78 93.83 MW-3 10.0 5.0- 10.0 5.84 97.71 91.87 MW-4 Abandoned MW-5 10.0 2.0-7.0 6.73 ND MW-6 9.0 4.0 - 9.0 4.86 93.29 88.43 MW-7 20.0 15.0-20.0 4.91 93.38 88.47 MW-8 12.0 7.0 - 12.0 8.04 101.37 93.33 M W-9 26.0 21.0 - 26.0 10.87 101.44 90.57 Taw - 00 10.0 5.0 -10.0 4.72 97.11 92.39 MW-11 9.5 4.5 - 9.5 6.77 94.41 87.64 MW-12 12.0 7.0 -12.0 5.07 101.70 96.63 feet bgs =Feet below ground surface feet TOC - Feet below top of ivell casing Table 2t Summary of Groundwater Sampling Results Incident Name: Former Stevcolmit Fabrics Comnaav Facility ED* NONCD0002543 Analytical Method (e.g., VOC by.SM6000B) or Field Measurement(FM)-> EPA 8260B EPA 9260B EPA 8260B EPA 8260B EPA 8260B EPA 8260B EPA 8260E EPA 8260B EPA 8260B EPA 8260B EPA 8260B EPA 8260B EPA 8160B EPA 8260D EPA 8260B EPA 8260E EPA 9260B Contaminant. of Concern/ Field Measurement-> ¢ P _ P •.• U .. _o V = u 5 P .3 9 w c t= o _ o a Well or SW ID Date Collected (m/dd/yy) Sample ID IDcideot Phase (Closure, 20 Day, LSA, etc.) MW-1 NE. <0.4 <0.4 <0.3 <0.3 <0.2 <0.4 <0.2 <0.1 <0.3 <0.2 NE <0.3 <0.2 <0.9 <0.4 <0.3MW-1 015 MW-1 <1.2 <0.13 <.21 <039 <0.17 <0.15 <0.21 <03 <0.13 <0.17 <OA4 <0.45 <0.19 <0.065 <017 <0.15 <0.32 006 MW-2 NE <0.4 <0.3 <0.3 83 25 <0.2 <0,1 <0.3 <0.2 NE <0.3 <0� 140 ]10 30 MW-2 015 MW-2 <12 <0.13 0.501 <0.19 <0.17 10 0,581 <0.1 <0.13 <O.17 <014 <0.45 <0.19 <0.065 50 3.506 j1Q/31MO606 MW-3 NE <04<04<030.867 23 <0.4 <0.2 <.1 <03 <02 NM <0 <<0.2 16 34 <0.3 MW-3 015 MW-3 <1.2 <.13 <0.21 0.497 10 <0,15 <0.21 <0.1 <0.13 <0.17 <0.14 <0.45 <0.19 <0.065 <0.17 <0.15 <032 MW-5MW-5 015 MW-5 <1.2 <0.13 <0.21 <0.19 N,17 <0. 15 <0.21 <0.1 <0.13 <0.17 <O:14 <0.45 <0.19 <0.065 <0.17 <0.15 <0.32 06 MW-6 NE <0.4 <0.4 <03 <.3 <0.2 <0.4 <0.2 <0.1 <0.3 <0.2 NE <0.3 <0.2 <0.9 <O.p <03MW-6 015 MW-6 <12 <0.13 <0.21 <0.19 <0.17 <0.15 <0.21 <0.1 <0.13 <0.17 <.14 <0.45 <0.19 <0.065 <0.17 <0.15 <0.32 11/l/2006 MW-7 NE <OA <0.4 <0.3 <0.3 <02 <0A <0.2 <O.l <0.3 <2 NE <0.3 <02 <0.9 <0.4 <03 MW-7 10/21/2015 MW-7 <12 <0.13 <0.21 <0.19 <0.17 <0.15 <021 <0.1 <O.I3 <0.17 <.14 <0.45 <0.19 <0.065 <0.17 <0.15 <0.32 10/31/2006 MW-8 NE <0.4 <0.4 <p.3 <.3 "OD <.4 <2 <0.1 <3 <.2 NE <0.3 <0.2 1200D IIOOD 590D MW-8 1021/2015 MW-8 <12 <0.13 S.O3D <7.9D <1.7D 430D. 16D 4:6JD <0.13 <0.17 <0.14 <0.45 <0.19 <.065 GODD 440D 170D 11/I/2006 MW-9 NE <O.q <0:4 <0.3 <0.3 <.2 <0.4 <p.2 <0.1 <0.3 <0.2 NE <0.3 <0.2 <0.9 <0.4 <0,3 MW-9 10/212015 MW-9 <1.2 2.9 3.7 <039 <0.17 <0.15 <0.21 <0.1 <0.13 <0.17 <0.14 <0.45 <0.065 <0.065 <0.17 <0.15 <.32 11/1/2006 Mw-10 NE 1 <.4 <0.3 <0.3 <0.2 <0.4 <0.2 <0.1 <0.3 '<.2 NE <0.3 70.2 1.1 <0.4 <0.3 MW-10 10/212015 MW-10 20 <0.13 <0.21 <0.19 <0.17 <0.15 <0.21 <0.1 1.8 6.2 2 8.3 <0.19 2.1 <0.17 <0.15 <0.32 11/l/2006 MW-I1 NE 0.9 <0.4 <0.3 1.2 <0.2 <0.4 <02 <0.1 <03 <02.

STANDARD PROCEDURES 1. Soil Sampling A. Sampling equipment for soil (split spoon samples, stainless steel hand auger, etc.) is decontaminated prior to and after use by washing with phosphate -free soapy water followed by a distilled water rinse, then an isopropyl alcohol rinse, followed by a triple rinse using distilled water. B. Soil samples are collected in laboratory -provided containers. Samples are stored and transported on ice according to EPA SW-846 protocol to a USEPA Drinking Water Certified laboratory under chain -of -custody procedures. A new pair of disposable medical gloves is worn each time a sample is collected. 2. Sample Handling and Shipping A. Immediately after sample collection, sampler will check the label for completeness. Samples will be placed into a cooler containing bagged ice. B. Chain -of -custody form will be completed and kept with the samples at all times inside the cooler in a plastic bag. C. Custody shall be maintained by the sampler until the coolers are prepared for transport and shipped. D. Glass sample bottles will be wrapped in bubble wrap packaging to eliminate the possibility of breakage. All sample containers will be placed upright in the cooler. Packaging materials of bubble wrap or styrofoam peanuts will be used. E. Cooler will be taped shut and drain plug will be sec1rely taped. F. Samples will be shipped or delivered to the laboratory within the specified holding time. G. Labs should be notified of the expected arrival. They will need to know: how many samples, analysis required, and expected arrival time. WATER LEVELS 1. Take cap off well, allow well to vent. 2. Test the indicator by placing the bottom in water. Inc light should come on. Replace the battery if necessary. Attach water level indicator to surveyor's tape. 3. Unreel the tape slowly down the well and watch for the light to indicate the probe is in the water. }. Pull the tape up about 2 inches. 5. Lower the tape down the well a tenth at a time until you see the light. Mark the point with a marker, clip, or finger. 6. The depth to water is the length indicated on the tape plus 12 inches. 7. Record the depth to water in the field notes. 8. Record the inside diameter of well in field notes. 9. Decontaminate probe and tape. PURGING WELLS Items Needed to Purge: Bucket, known volume Depth to well bottom measurement Disposable Gloves Field Notes Water Levels 1. Determining Amount of Water to Remove from Well A. Subtract water level from depth to bottom. B. Multiply the number from Step A. by 0.163 fora 2 inch LD. well. C. Multiply the number from Step B by 3. This number is equal to 3 well volumes in gallons, the minimum needed to properly purge the well. For instance, if the well is a 2—inch I.D. well that is 30 feet deep, and the depth to water is 20 feet, the number of gallons needed to purge the well is: B. 10 x .163 = 1.63 C. 3 x 1.63 = 4.89 gallons 2. Bailing Method (using dedicated or disposable bailer) A. Place bucket near well. B. Wear Disposable Gloves. 1. Change and discard between wells. C. Lower bailer down well, pull up, pour into bucket. D. Remove required volume and note time after each well volume. E. After each well volume is removed, measurements of pH, temperature, and specific conductance will be taken. If after 3 well volumes these measurements are not stable ( + 10%) purging will continue. Consecutive stable measurement must be recorded before purging will be considered complete. These values, times, and corresponding volumes will be recorded. F. Record the volume removed and method used in field notes. G. It is important to make note of the color, odor, and amount of sediment, if any in the water, in the field notes. SAMPLING OF WELLS Items Needed to Sample: Sample Bottles Disposable Gloves pH Meter Conductivity Meter Thermometer Field Notes 1. Take conductivity measurement. A. Standardize meter according to manufacturer's instructions. B. Lower probe into the water that is collected in a beaker. C. Take 2 conductivity readings (or until stable), record in field notes. D. Rinse probe with distilled water. 2. Take pH temperature measurements. A. Standardize meter according to manufacturer's instructions. B. Lower probe into the water that is collected in a beaker. C. Record temperature reading from display in field book. D. Take 2 pH readings (or until stable). 1 . Rinse probe with distilled water. 3. Label sample bottles with sample ID, date/time, project #, collector, and preservative used. 4. Wear disposable gloves. Change and discard between samples. 5. Lower bailer down well. 6. Discard the first bailer of water. 7. Pour water directly from bailer into sample bottles that do not require filtering. 8. Continue bailing until adequate water volume has been collected. SAMPLE HANDLING AND SHIPPING Immediately after sample collection, sampler will check the label for completeness. Samples will be placed into a cooler containing bagged ice. 2. Chain —of —custody form will be completed and kept with the samples at all times inside the cooler in a plastic bag. 3. Custody shall be maintained by the sampler until the coolers are prepared for transport and shipped. 4. Glass sample bottles will be wrapped in bubble wrap packaging to eliminate the possibility of breakage. All sample containers will be placed upright in the cooler. Packaging materials of bubble wrap or styrofoam peanuts will be used. 5. Cooler will be taped shut and drain plug will be securely taped. 6. Samples will be shipped or delivered to the laboratory within the specified holding time. 7. Labs should be notified of the expected arrival. They will need to know: how many samples, analysis required, and expected arrival time.
