Site Assessment Activities
Amicale/Woonsocket Mill
4701 Monroe Road
Charlotte, North Carolina
1.0 Introduction and Background
In accordance with our authorized scope of work, Hart & Hickman, PC (H&H) has completed
site assessment activities at the Amicale/Woonsocket Mill (Woonsocket) site located at 4701
Monroe in Charlotte, North Carolina. 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

• 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.

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.

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.

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.

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.

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

• 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.

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.

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.
