A site location map is provided as Figure 1. The site is approximately 15.5 acres in area and contains an approximate 205,000 square ft manufacturing building. The building is located in the western portion of the site, a concrete wastewater basin is located in the central portion of the site, and the eastern portion of the site is wooded and vacant. A site plan is provided as Figure 2. The facility is used for spinning, winding, dyeing, and finishing fabrics such as cashmere and camel hair. H&H reviewed a previous Phase I Environmental Site Assessment (ESA) conducted in September 2000 by Cooper Environmental. The results of the Phase I ESA indicated several areas of concern at the site and recommended soil and ground water sampling. H&H also reviewed an underground storage tank (UST) closure report prepared by Integrity Environmental Consultants dated August 17, 1994. The results of sampling conducted before and after removal of the 30,000-gallon fuel oil UST did not indicate significant soil or ground water impact in the area of the UST. The location of the former UST is indicated in Figure 3. H&H also conducted a site visit with Mr. Bob McCarty of Amicale/Woonsocket on November 18, 2004. This site visit was a preliminary review of site operations and was not a detailed analysis of site conditions. At this time, documents such as old site maps were also reviewed at the facility. Based upon the results of these activities, multiple areas of potential environmental concern were identified at the site. The primary areas of concern included: S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 2 • Dye house operations including multiple floor trenches and pits; • Wet finishing area floor trenches and pits; • Wastewater basin including reports of periodic overflow of the basin during storm events; • Former septic system (aboveground concrete structure) noted on historical map; • Dye house wastewater above ground concrete tank and associated sump and active sewer line; • Former dye house wastewater sewer line noted on historical map; • Former wastewater collection structures (weir box/sump) noted on historical maps and during the site visit; • Machine shop operations including shop sink drainage to the ground outside of the building; • Former incinerator noted on historical map; • Oil/water separator; • Deep sump located adjacent to oil/water separator; • Dry finishing area use of chlorinated solvents for spot cleaning; • Noted use of trichloroethene and methylene chloride in QC laboratory; • 20,000-gallon former fuel oil above ground storage tank containment; • Bale press and sump containing water and oil with noted surrounding staining to concrete; and • Two current and one former transformer areas located on Chippendale Rd. As a preliminary means of assessing the potential for significant environmental concerns at the site, H&H conducted an initial phase of ground water sampling on December 2, 2004. The results of the ground water sampling did not indicate significant ground water impact. As such, a soil investigation was subsequently conducted on December 20 to 21 to further assess conditions at the site. The methods and results of the soil and ground water assessment activities are provided in the following sections. S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 3 2.0 Sampling Activities 2.1 General Field Practices H&H conducted the ground water sampling activities at the site on December 2, 2004. The soil sampling activities were conducted during the period December 20 and 21, 2004. Field activities consisted of 1) advancing borings using a direct push technology rig (DPT); 2) installing five temporary monitoring wells using DPT and screening soil samples for impact during boring advancement; 3) collecting ground water samples for laboratory analysis; 4) installing borings by DPT or stainless steel hand auger in the areas of potential concern indicated above; and 5) collecting soil samples for laboratory analysis. Soil samples were selected for laboratory analysis based on field screening using a photoionization detector (PID), visual observations, depths of the structures of concern, and potential odors. H&H utilized a North Carolina-certified laboratory for sample analytical work. Dedicated laboratory-supplied sample bottles were used for sample collection. A chain-of-custody record was completed for samples collected and included the sample description, date collected, time collected, matrix, sample container information, and analyses. The chain-of-custody was signed by H&H prior to placement in an iced cooler for shipment to the analytical laboratory. Prior to shipment, the cooler was closed with a seal indicating the H&H representative’s signature and date such that potential disturbance of the cooler contents could be detected by the laboratory. The laboratory chain-of-custody and analytical data sheets are provided in Appendix A. Results are discussed in Section 3.0. 2.2 Ground Water Sampling In the initial phase of the site assessment, H&H collected ground water samples from five areas of the site to assess shallow ground water conditions in and downgradient of potential areas of concern. The areas where wells were installed included: 1. the vicinity of the dye house (TW-4); S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 4 2. the vicinity of the machine shop and former wastewater collection structures near the northern portion of the building (TW-3); 3. in the containment area containing the oil/water separator, deep sump, and concrete wastewater AST (TW-2); 4. along the eastern side of the building (TW-1); and 5. near the wastewater containment basin (TW-5). The locations of the temporary wells are indicated in Figure 3. The ground water samples were collected from temporary one-inch diameter monitor wells installed with a direct push technology (DPT) rig. During boring advancement, soil samples were collected in continuous 4- ft intervals. Collected soil samples were logged in the field for lithologic purposes and evidence of staining or discoloration. In addition, the soil samples were screened for the presence of organic vapors with a field organic vapor analyzer (OVA). No soils samples were selected for laboratory analysis in this initial phase. Temporary monitor wells were installed in each of the borings which were constructed of one- inch diameter PVC casing and a 15-ft section of screen. The total depths of the wells ranged form 25 to 30 ft below ground surface. Table 1 presents temporary well data construction data. Following installation, each well was developed and sampled with a disposable bailer. During the development process, field readings of pH, conductivity, temperature, and turbidity were measured. The ground water sample from each well was analyzed for volatile organic compounds (VOCs) by EPA Method 8260 and for the following metals: eight RCRA metals (arsenic, barium, cadmium, chromium, mercury, lead, silver, and selenium) plus copper, nickel, and zinc. One day after sampling, the depth to ground water in each well was measured with an electronic depth to water probe. In addition, the top of casing elevation of each monitor well was determined using survey techniques. Depth to water and top of casing measurements are presented in Table 1 along with calculated ground water elevation data. The temporary monitor wells were abandoned following the sampling and gauging activities. S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 5 2.3 Soil Sampling During the second phase of sampling, H&H collected soil samples from 21 soil borings advanced in potential areas of concern at the site. The areas selected for soil sampling and their respective analysis are indicated in the table below. The locations of the soil borings are indicated in Figure 3. Potential Area of Concern Borings Laboratory Analyses Dry finishing area sump SB-1 VOCs (8260) and RCRA metals, Cu, Zn, and Ni Wet finishing area pits SB-2, SB-3 VOCs (8260) and RCRA metals, Cu, Zn, and Ni Dye house pits SB-4, SB-5, SB-6, SB-7 VOCs (8260), RCRA metals, Cu, Zn, and Ni Oil/water separator and associated deep sump SB-8 VOCs (8260), PAHs (8270), VPH/EPH (MADEP methods), Pb, and Cr 20,000 gallon fuel oil AST SB-9, SB-10, SB-11 Oil and grease (9071) Maintenance shop building former exterior sink discharge SB-12 VOCs (8260) Bale press and sump SB-13 Oil and grease (9071) Wastewater collection sump SB-14 VOCs (8260) and RCRA metals, Cu, Zn, and Ni Former wastewater weir box/sump SB-15 VOCs (8260) and RCRA metals, Cu, Zn, and Ni Former septic structure SB-16 VOCs (8260) and RCRA metals, Cu, Zn, and Ni Former incinerator area SB-17 VOCs (8260) and RCRA metals, Cu, Zn, and Ni Wastewater basin/pond SB-18 VOCs (8260) and RCRA metals, Cu, Zn, and Ni S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 6 Wastewater sewer line SB-19, SB-20 VOCs (8260) and RCRA metals, Cu, Zn, and Ni Former wastewater sewer line SB-21 VOCs (8260) and RCRA metals, Cu, Zn, and Ni Per request, no samples were collected in the transformer areas. Amicale/Woonsocket has notified Duke Power of staining in the vicinity of the transformers and has requested that they respond to this issue. Background Soil Samples Because metals are naturally occurring in area soils, background soil samples were collected near the southeastern corner of the site building away from potential areas of concern (Figure 3). H&H collected samples by DPT from depths of 2 ft below grade (BKG-2), 4 ft below grade (BGK-4), and 6 ft below grade (BKG-6). Samples were analyzed for RCRA metals, Cu, Zn, and Ni by the aforementioned methods. The soil samples were collected by direct push technology (DPT) rig or by hand auger in inaccessible areas. During boring advancement, soil samples were collected with the DPT in continuous 4-ft intervals. Collected soil samples were logged in the field for lithologic purposes and evidence of staining or discoloration. In addition, the soil samples were screened for the presence of organic vapors with a field organic vapor analyzer (OVA). One soil sample was selected from each boring location for laboratory analysis. Sample depth for the borings ranged from 2 to 14 ft below grade depending on field screening and the depth of the suspect structures of concern. Table 3 presents the sample depths selected for laboratory analysis from each soil boring. Following sample collection in each area, the soil borings were abandoned. If needed, the surface materials were patched after boring abandonment. S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 7 3.0 Sample Results The results of the ground water analyses are summarized in Table 2 and the results of the soil sample analyses are summarized Table 3. The laboratory analytical data sheets are provided in Appendix A. In the summary tables, the analytical data have been compared to some regulatory action and screening levels. The ground water data were compared to the North Carolina ground water standards. For the soil analytical data in Table 3, the data were compared to published screening levels for residential direct contact, industrial direct contact, and soil to ground water leaching. The soil data were compared to the North Carolina Department of Environment and Natural Resources (DENR) Inactive Hazardous Sites Unrestricted Use (i.e., residential) Soil Remediation Goals (SRGs), the EPA Region IX Preliminary Remediation Goals (PRGs) for Industrial/Commercial sites, and the DENR Groundwater Section cleanup levels (CLs) considering soil to ground water transport. The SRGs and PRGs are health-based standards based upon direct exposure to soil, and the Groundwater Section CLs are based upon protection of ground water due to leaching of water through impacted soil. Where SRGs and CLs were not available for a particular compound, the corresponding EPA Region IX PRG for residential use or soil to ground water transport were used for comparison. In addition to the published screening level concentrations noted above, because metals are naturally occurring, metals concentrations in soil were also compared to metals concentrations detected in the site background samples. In some cases, the background levels were greater than the screening levels. Soil concentrations were not considered elevated unless they were above a screening level and greater than two times a corresponding background concentration. Ground Water Results Depth to ground water in the wells ranged from 11 ft below ground level at the wastewater pond to 23 ft below ground level near the manufacturing building. Ground water flow direction was determined to be to the east which is consistent with site topography. S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 8 No significant OVA readings were detected in soil samples collected during temporary well installation. No odors were detected in the soil samples from the monitor well borings expect some potential hydrocarbon odors at TW-2. On-site personnel indicated that some underground lines were present in this area associated with the former fuel oil UST and/or former fuel oil AST. A soil sample was collected from this area during soil sampling (SB-9) but did not contain oil and grease levels above DENR action levels. The results of the ground water analyses did not indicate compound concentrations in ground water above ground water standards. No VOCs were detected in TW-1, TW-3, TW-4, or TW-5. Low concentrations of several petroleum related VOCs were detected in TW-2 near the containment area north of the site building; however the concentrations are well below North Carolina ground water standards. Low concentrations of metals were also detected in the ground water samples. Metals are naturally occurring and therefore the detected concentrations are likely indicative of naturally occurring concentrations. As with the VOCs, the concentrations are well below North Carolina ground water standards. Based on the ground water sample results, there is no evidence of widespread or significant ground water impact at the Amicale/Woonsocket Mill site. Soil Sample Results No concentrations of analyzed compounds were detected above screening levels and/or significantly above background levels for metals for soil samples collected from the following areas: • The dry finishing sump (SB-1); • The wet finishing pits (SB-2 and SB-3); • The dye house pits (SB-4 through SB-7); • The oil/water separator and associated sump (SB-8); • The exterior maintenance shop sink discharge area (SB-12); S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 9 • The interior bale press (SB-13); • The wastewater collection weir/sump (SB-14); • The concrete wastewater collection structures (SB-15); • The former septic tank area (SB-16); • The former incinerator area (SB-17); and • The wastewater pond (SB-18). Some potentially elevated metals levels (as compared to background levels) were detected in several samples from these areas; however the metals concentrations were below the screening levels. Only two areas indicated soil impacts of potential concern: the fuel oil AST and the current and former wastewater sewer line area. Soil sample results from these two areas are discussed below. Fuel Oil AST The soil sample collected from the north end of the fuel oil AST (SB-11) indicated an oil & grease concentration of 411 mg/kg at 2 ft to 4 ft which exceeds the DENR Groundwater Section action level of 250 mg/kg. The northern end of the containment appears to be the end where fuel oil off-loading occurred. There was no evidence of obvious soil impact such as staining in this area. The soil sample collected on the south end of the containment (SB-10) did not indicate detectable concentrations of oil and grease. In addition, as noted previously, a soil sample (SB- 9) collected south of the containment near the reported location of some underground fuel oil lines did not indicate detectable levels of oil and grease. Based upon the lack of field evidence of impact such as soil staining, the fact that the other sample collected from the containment did not indicate impact, and that the detected concentration only slightly exceeds the action level, there does not appear to be a significant amount of impacted soil in this area. S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 10 Current and Former Sewer Line Three soil borings were advanced near the current and former wastewater sewer lines. The inferred sewer line locations were based upon manhole locations, straightline distances between points where the lines were estimated to be present (ex., between exposed line and wastewater pond), and maps showing the locations of the current and former lines. SB-19 was collected near the western area where the current and former lines are located, SB-20 was located near the inferred location of the current line, and SB-21 was located near a manhole that appeared to be associated with the former sewer line. No VOCs or elevated metals levels were detected in the soil sample collected from boring SB-19 near the western extent of the lines. At SB-20 (8-10 ft), no VOCs were detected, however, elevated concentrations of some metals were detected. As compared to background, the following metals were detected significantly above background: barium (474 mg/kg), chromium (289 mg/kg), copper (321 mg/kg), nickel (153 mg/kg), and zinc (171 mg/kg). However, of the compounds detected, only the chromium concentration exceeded its soil-to-ground water screening level. No other metals concentrations exceeded their soil to ground water screening levels, and no metals concentrations (except possibly chromium) exceeded health based standards. It should be noted that the unrestricted use health based standard for chromium is in part due to its valence (i.e., trivalent chromium versus hexavalent chromium). The valence state of the chromium was not determined; however, our experience is that it is unusual for a large portion of the total chromium to be the more toxic hexavalent chromium. In SB-21 (8-10 ft) located near the former sewer line manhole, no significantly elevated metals were detected, however low levels of several VOCs were detected. The VOCs detected were the chlorinated solvents chloroform (0.0022 mg/kg), 1,1-dichloroethane (0.0033 mg/kg), 1,1- dichloroethene (0.211 mg/kg), 1,1,1-trichloroethane (0.801 mg/kg), and 1,1,2-trichloroethane (0.0038 mg/kg). Of the compounds detected, only 1,1-dichloroethene exceeded its soil to ground water CL. None of the other VOCs exceeded their soil to ground water CLs and no VOC concentrations exceeded their respective residential or industrial/commercial health-based screening levels. S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 11 4.0 Recommendations The results of the ground water sampling did not indicate evidence of widespread or significant ground water impact at the site. The results of the soil sampling indicated two areas where soil impacts were detected above screening levels: the fuel oil AST and portions of the current and former wastewater sewer lines. In the fuel oil AST area, one soil sample from the northern end of the containment contained soil impact above DENR action levels. Based upon the lack of field evidence of impact such as soil staining, the fact that the other sample collected from the containment did not indicate impact, and that the detected concentration only slightly exceeded the action level, there does not appear to be a significant amount of impacted soil in this area. In the area of the current and former sewer line, several metals or VOCs were detected in two soil samples above screening levels at a depth of 8-10 ft below ground surface. Of the compounds detected, only 1,1-dichloroethene and chromium exceeded their soil to ground water transport screening levels. No compounds in these two samples exceeded their respective health based standards although there is a possibility that chromium could exceed its residential standard based upon its valence state. With regard to further actions, there are several avenues that could be taken. Two of the recommended avenues are discussed below although there are other options that are not presented below. One option would be participation in the DENR Brownfields Section program. In this program, a prospective developer of a property who is not responsible for causing the contamination enters into a "brownfields agreement" with DENR. In the agreement, DENR defines the necessary cleanup and land management actions needed to make the site safe for redevelopment and the prospective developer receives liability protection for the contamination. Typically, the results of the assessment activities reported herein are provided to DENR and then DENR requires additional assessment prior to entering into an agreement. The additional assessment may S:\Master Files\AAA-Master Projects\Krug\KRU-001\woonsocket KRU-001 Phase II ESA Report.doc Hart & Hickman, PC 12 include such items as additional soil or ground water testing in areas of potential concern. The final Brownfield agreements may require limited remedial actions, land use restrictions, or monitoring but do not typically require extensive remediation. The second avenue would be to conduct further assessment of the identified areas of concern along the current and former sewer lines to determine the nature and extent of soil impact and the potential for localized ground water impact in this area. Depending upon the results of these additional assessment activities, it may be more cost and time effective to simply remediate the areas of identified soil impact rather than participating in the Brownfields program. If the area is determined to be extensive or to have ground water impact above standard, then participation in the Brownfield program could be determined at that time. In this second approach, because soil impact in the area of the fuel oil AST appears to be minor, remediation of this soil upon removal of the tank would likely be advisable versus additional assessment.
