EXECUTIVE SUMMARY
Worldtex, Inc. (Worldtex) retained GaiaTecb Incorporated to conduct a Limited Phase II Site
Investigation of the Former Regal Manufacturing (Regal) facility located at 212 12lh Avenue NE in
Hickory, Catawba County, North Carolina. The purpose of this investigation was two-fold. The
first goal was to evaluate whether subsurface contamination existed on site. The second goal, if
contamination was tdentified on site, was to evaluate whether the site is the source of contaminants
or the source is off site and bas migrated onto the site.
The site consists of three contiguous parcels totaling 2.03 acres of land located between 12lh
A venue NE and lllh A venue NE. These parcels make up the fonner manufacturing area of the
site. In addition to these parcels, a 0.61-acre parking area is located across lllh Avenue NE to the
south of the manufacturing portion of the site. Approximately 60% of the area of the
manufacturing portion of the site is occupied by buildings. The remainder consists of asphalt and
concrete-paved parking and loading areas and a small grassy tract along the northern side of the
building. The parking area across lllh Avenue NE is fenced and paved.
The site is currently vacant and unused. From as early as 1956, the site operated as a textile
manufacturing facility. Regal, the most recent occupant of the site, manufactured elastic yam on
site from the 1960s until 1999 when manufacturing operations ceased.
The surrounding properties consisted of primarily commercial and industrial properties from as
early as the 1950s.
GaiaTech conducted an Impact Review of the site in February 2007 that evaluated two previous
GaiaTech reports (2001 Phase I and 2002 Phase II) and an EnviroAssessments, PLLC (EA) report
(2007 Phase l), as well as regulatory documemation pertaining to several leaking underground
storage tank facilities in the vicinity of the site. This review identified tetrachloroethylene (PCE)
and trichloroeth}lene (TCE) on an adjacent property.
On February 28 and March 5-6, 2007, Gaia Tech installed and sampled a total of 6 soil borings
(SB-1 through SB-6) and four monitoring wells (MW-1 through MW-4) at the site. Three soil
samples and four groundwater samples were analyzed for volatile organic compounds (VOCs).
Two soil samples were analyzed for Total Petroleum Hydrocarbons (TPH). In addition, a sample
of oil from the hydraulic lift on site was analyzed for the presence of polychlorinated biphenyls
(PCBs).
GaiaTech returned to the site on April 5, 2007 to install three soil borings (SB-8 through SB-10)
along the western property boundary. Three soil samples and three groundwater samples were
collected for analysis of VOCs.
Based on soil screening and sampling results, no evidence of impact to site soils was identified
during the installation of soil borings.

1.0 INTRODUCTION
Worldtex, Inc. (Worldtex) retained GaiaTech Incorporated to conduct a Limited Phase II Site
Investigation of the Former Regal Manufacturing (Regal) facility located at 212 12th Avenue NE in
Hickory. Catawba County, North Carolina. The purpose of this investigation was to evaluate
whether subsurface impacts exist on site.
1.1 Site Description and Background
The site consists of three contiguous parcels totaling 2.03 acres of land located between
12111 A venue NE and 11 111 A venue NE. These parcels make up the manufacturing area of the
site. In addition to these parcels, a 0.61 -acre parking area is located across ll th Avenue NE
to the south of the manufacturing portion of the site. The northernmost parcel of the
manufacturing portion of the site is occupied by a large manufacturing building including
an office area and two smaller manufacturing buildings along the western property
boundary. The southern two parcels are occupied by a loading dock associated with the
manufacturing building and two smaller buildings. Approximately 60% of the area of the
manufacturing portion of the site is occupied by buildings. The remainder consists of
asphalt and concrete-paved parking and loading areas and a small grassy tract along the
northern side of the building.
The site is currently vacant and unused. From as early as 1956, the site operated as a
textile manufacturing facility. Historical occupants include Reaco Hosiery Mills, Madaris
Hosiery Mills, the Elastic corporation, and Realspan Corporation. In the 1960s, an
automotive repair business operated in one of the smaller buildings located to the south of
the manufacturing building. Regal, the most recent occupant of the site, manufactured
elastic yarn on site from the 1960s until 1999 when manufacturing operations on site
ceased.
According to representatives of Worldtex, Regal utilize some hazardous chemicals in its
maintenance processes. Details regarding historical operations, prior to Regal's, are not
known. As a result, there is a potential for impacts to the site resulting from historical on-
site operations.
The surrounding properties consisted of primarily commercial and industrial properties
from as earl] as the 1950s. Two gasoline stations and a self-serve car wash have bordered
the manufacturing portion of the site to the west since at least 1961. The manufacturing
portion of the site was bordered to the north, across 12m Avenue NE, by a gasoline station,
dwelling, and textile manufacturing facility. These properties are currently occupied by a
church, TCBY Frozen Yogurt store, and a vacant paved parking lot (which was previously
occupied by DunMore Furniture). The site has been bordered to the east, across 3rd Street,
by Hickory High School since at least 1973. The manufacturing portion of the site is
Projc:c1 !'1/o. 6330-420-1 Former Regal Manufacrurmg
Hickory, 1'\onh Carolina
GAI\TECII hCORPORATED Confidential
bordered to the south across lllh A venue NE by the parking lot associated with Regal, a
restaurant, and commercial retail facilities. These properties were historically residential
and retail.
GaiaTech conducted a Phase 1 Environmental Site Assessment (ESA) of the site in
November 2001 that identified potential impacts to the site from the former underground
storage tank (USn, hydraulic lift, historical textile manufacturing operations, and potential
impacts from leaking UST and hazardous waste generating facilities in the vicinity of the
site.
Subsequent to GaiaTech's Phase I ESA, a Focused Phase n Investigation was conducted by
GaiaTech in January 2002 to evaluate potential impacts in the vicinity of the former UST.
No evidence of in1pact to soil was identified. However, no groundwater san1ples were
obtained.
An Impact Review of the site was conducted by Gaia Tech in February 2007. Gaia Tech
evaluated the previous reports, as well as regulatory documents related to nearby UST
facilities including Viewmont Exxon and Servco, each located adjacent to the west of the
site. This review concluded that the Viewmont Exxon and Servco facilities have bad
releases of petroleum products. In addition, PCE and TCE were observed in groundwater
cotlected at the Servco facility.
In an effort to determine whether the site bas been impacted b) contaminants observed at
the adjacent property and whether these contaminants might have originated on site,
GaiaTech targeted the investigation to evaluate areas downgradient and upgradient of the
manufacturing plant. A comparison of these results will aid in pinpointing the source of
potential contaminants. It is possible that the PCE and TCE have multiple sources.
1.2 Scope of Work
On February 28 and March 5-6, 2007, Gaia Tech installed and san1pled a total of 6 soil
borings and four monitoring wells at the site. Three soil san1ples and four groundwater
san1ples were analyzed for: volatile organic compounds (VOCs). Two soil samples were
analyzed for Total Petroleum Hydrocarbons (TPH). In addition, a sample of oil from the
hydraulic lift on site was analyzed for the presence of polychlorinated biphenyls (PCBs).
The locations of the borings are rationalized as follows.
• Two borings (SB-1 and SB-2) were installed in areas downgradient of the
manufacturing building and near the location of a monitoring well where elevated
concentrations of chlorinated solvents were observed at an adjacent property.
• Two borings (SB-3 and SB-4) were installed upgradient of the manufacturing
building to assess the potential for migration of contaminants to the site from an
upgradient off-site source.

• Two borings (SB-5 and SB-6) were installed to evaluate potential impacts from a
release of oil from the hydraulic lift on site.
On April 5, 2007, Gaia Tech returned to the site to install three soil borings along the
western property boundary. One soil sample and one groundwater sample was collected
from each boring for analysis of VOCs. The locations of the borings are rationalized as
follows.
• One boring (SB-9) was installed within the plant building near the southwestern corner
of the site building. This boring was placed in an area upgradient of a monitoring well
where elevated concentrations of chlorinated solvents were observed at an adjacent
property.
• Two borings (SB-8 and SB-10) were installed in the northwestern corner of the sire in
areas upgradient and cross gradient of the manufacturing building to assess the potential
for migration of contaminants to the site from an off-site source.
1.3 Geology and Hydrogeology
According to the Soil Survey of Catawba County, N011h Carolina, site soils are classified
as Cecil Sandy Loam with 2 to 6 percent slopes. The Cecil series consists of well-drained
soils on uplands. These soils formed in residuum from acidic rock, including granite-gneiss
and granite. It is a well-drained soil on fairly smooth, broad ridges and uplands. Typically,
the surface layer is dark grayish-brown and brown sandy loam approximately 7 inches
thick. The subsoil is approximately 43 inches thick and is dominantly red, firm clay in the
upper part and red, friable clay loam monied with brown in the lower part. The
substratum, to a depth of approximately 75 inches, is mottled red and brown sandy loam.
During GaiaTecb's investigation, the subsurface materials typically encountered in the soil
borings consisted of micaceous silty sands that were mottled with (red, black, and yellow)
clayey pockets and intersected by loose seams of weathered rock fragments. In general,
GaiaTech observed severely weathered rock at depths ranging from approximately 20 feet
to 30 feet below ground surface (bgs) across the site. Less severely weathered rock was
encountered at depths ranging from approximately 30 to 40 feet bgs across the site. Within
the 40-45 ft bgs extent of this investigation, competent rock was encountered in the area
approximated by the southwestern corner of the plant at approximately 35 feet bgs.
Groundwater was observed ar depths ranging from approximately 30 to 37 feet bgs
throughout the site. Based on measurements collected during the field component of this
assessment, groundwater at the site is flowing in a southwesterly direction.

2.0 SOIL SAMPLING
2.1 Methodology
Prior to conducting field activities, GaiaTech completed a subsurface utility clearance
through the North Carolina One Call Center.
On February 28, March 5-6, 2007, and Apri15, 2007, GaiaTech supervised the installation
of 8 soil borings using a truck-mounted Geoprobe~ unit to depths ranging from 12 to 40
feet bgs. During boring installation, continuous soil samples were collected using a five-
foot stainless steel macrocore sampling system with disposable acetate liners. Upon
retrieval from the sample liner, soils were visually inspected for evidence of contamination
and described on the basis of lithology, color, texture, odor, and relative moisture. Boring
logs are presented in Appendix A.
Representative samples from each tube were split into separate sample bags: one used for
field screening and the other for laboratory analyses (as described below). Field screening
was accomplished using a portable photo-ionization detector (PID) equipped with a l0.6eV
lamp, calibrated to a 100 volumetric parts per million (ppmv) isobutylene standard.
Specific procedures in screening soils are as follows:
• The soil sample was sealed in a ziploc bag.
• The sample bag was labeled with the boring number and sample interval.
• The sample was allowed to reach ambient temperature.
• The PID was inserted into the headspace above the soil-air interface.
• The maxin1um PID reading was recorded for each sample.
The soil sample from each boring that exhibited the highest PID reading was selected for
laboratory analysis. The bagged portions of selected san1ples were placed into laboratory
prepared sample bottles and submitted under strict chain-of-custody procedures to
Analytical Environmental Services, Inc. of Atlanta, Georgia.
To avoid cross contanlination. all down-hole soil boring and non-dedicated sampling
equipmem was decomarninated using an Alconox·/water solution and water rinse.
Soil borings SB-1 through SB-4 were converted to temporary 2-inch diameter monitoring
wells (see Section 3.0) to facilitate the collection of groundwater samples. Soil borings SB-
8 through SB-9 were converted to temporary l-inch diameter temporary monitoring wells
(see Section 3.0) to facilitate the collection of groundwater samples. Upon receipt of
analytical results, GaiaTech along with Worldtex determined that the wells should be
converted to permanent monitoring wells to facilitate furure sampling needs at the site.
In addition to these borings, GaiaTech collected soil samples from a depth of
approxinlately 1.5 feet bgs from two shallow hand auger borings installed near the

hydraulic lift on site. These samples were placed directly into laboratory prepared bottles
and submitted under strict chain-of-custody procedures to Analytical Environmental
Services, Inc. of Atlanta, Georgia.
2.2 Soil Regulatory Standards
Comaminated Soil Clean-Up Levels (Table 3) of the Groundwater Section Guidelines for
the Investigation and Remediation of Soil and Groundwater prepared by the Department of
Environment and Natural Resources Division of Water establish target concentrations for
contaminants in soil.
2.3 Soil Sampling Results
The soil analytical results are presented in Table l. The approximate locations of the
borings are shown on Figure 2. Complete laboratory analytical reports are included in
Appendix B. No chemicals were identified at concentrations greater than the laboratory
detection limits in any soil boring.
2.4 Summary
Based on soil screening and sampling results, no evidence of impact to site soils was
identified during the installation of soil borings.

3.0 GROUNDWATER SAMPLING
3.1 Methodology
In order to evaluate potential impacts to groundwater, four borings SB-1, SB-2, SB-3, and
SB-4) were over-drilled using hollow-stem augers (SB-1) and air rotary (SB-2, SB-3, and
SB-4) in order to construct permanent groundwater monitoring wells. Permanent wells
were constructed by inserting 2-inch diameter PVC screen and riser into the borehole.
Temporary wells were screened to intercept the shallow groundwater table using 0.010-
inch rnachine-sloned screen. A silica-sand pack was placed in the annulus to a depth of one
foot above the top of the screen. A two-foot bentonite plug was then placed over the sand
pack to seal the screen, and prevent the infiltration of surface water. Cemem grout was
used to fill the remainder of the borehole to a depth of approximately 6 inches bgs.
Permanent wells were completed with flush-mount man hole covers.
The monitoring wells were purged and sampled using a submersible pump utilizing
disposable/dedicated tubing. The submersible portions of the pump were decontaminated
using an Alconox·/water solution and water rinse. Groundwater samples were collected
directly into laboratory prepared containers with the appropriate preservative, labeled and
placed on ice for transportation. Samples were delivered under strict chain-of-custody
procedures to Analytical Environmental Services, Inc. of Norcross, Georgia.
After receipt of groundwater analytical results, the temporary wells were converted to
permanent groundwater monitoring wells b) grouting from the bentonite plug to the
surface and finishing with a flush mount manhole cover and concrete pad.
On April5, 2007, GaiaTech collected an additional three groundwater samples from soil
borings SB-8, SB-9, and SB-10. Soil borings were converted to temporary wells by
inserting a length of l-inch diameter PVC screen and riser into the borehole. Using a
peristaltic pump with dedicated tubing, one groundwater san1ple was collected from each
boring. Following san1ple collection, the PVC screen and riser were removed and the
boring backfilled with bentonite and grout.
3.2 Groundwater Regulatory Standards
Class GA Standards outlined in the North Carolina Administrative Code Title 15A,
Subchapter 2L, Section 0202 (15A NCAC 2L.0202 are the applicable regulatory standards
for this investigation.
