INTRODUCTION
February 2006 Annual Sampling Event Report
Davis Park Road TCE Site
Section: 1
Revision: 0
Date: May 2006
Weston Solutions, Inc., (WESTON@) has been tasked by the U.S. Environmental Protection
Agency (EPA) Region 4 to perform the Long Term Response Action (LTRA) at the Davis Park
Road Trichloroethene (TCE) Site in Gastonia. North Carolina. The work is conducted under the
Region 5 Remedial Action Contract (RAC) Program and implemented as a contract crossover to
Region 4. Contract Number 68-W7-0026, Work Assignment Number 205-RALR-04PN. The
current L TRA includes monitoring the bedrock aquifer contaminant plume by sampling a
network of bedrock wells for volatile organic compounds (VOCs) on a quarterly basis for one
year, semiannually for two years, and annually thereafter for 27 years, pending review of
analytical results, to ensure the plume is in fact naturally attenuating. This report presents data
from the fourth year of the L TRA, the first annual sampling event.
1.2 BACKGROUND
The Davis Park Road TCE Site is located within the Gastonia Extra Territorial Jurisdiction area
along Davis Park Road, south of Hudson Boulevard and north of Blackwood Creek in the
southwestern portion of Gastonia, Gaston County, North Carolina. The site consists of an area of
reportedly contaminated soil behind a building that is located at 2307 Davis Park Road (Davis
Park Auto Repair), and a plume of contaminated groundwater that emanates from this property
and extends south along Davis Park Road to Blackwood Creek. The site also includes the Cedar
Oak Park subdivision located on the east side of Davis Park Road within the confines of Cedar

Oak Circle as well as areas along the western side of Davis Park Road. Figure 1-1 presents a site
map for the Davis Park Road TCE Site.
The plume of contaminated groundwater underlies residential areas along the plume's entire
horizontal extent. The contaminant levels and aerial extent are further described in Section 1.3.2.
At the time of the discovery of contaminants in the groundwater (March 1990). a majority of the
residences throughout the site were supplied water by residential water supply wells. As a result
of the continued migration of the plume. groundwater supplying many of these residential water
wells became contaminated with the chlorinated hydrocarbons found in the plume. Since that
time, several neighborhoods within the site have been connected to the Gastonia public water
supply to reduce the potential health threat from the contaminants. In 1996. many of the houses
within the Hedgewood Circle neighborhood, which borders the northern edge of the site. were
connected to the public water supply. In late I 997 and early I 998, after petitioning the city for
water services. all of the homes in the Cedar Oak Circle subdivision, which dominates the
eastern side of the site. were connected to the public water supply. Approximately 130 homes
within the site were receiving water from residential water supply wells prior to Remedial Action
(RA) activities. Over half of these homes (approximately 75) had water supply wells that were
or could potentially be affected by the contaminant plume as depicted in the I 998 Remedial
Investigation (RI) report. In August 2000, five of these residences were supplied with carbon
filtration units, and in September 2000, sixty-four (64) of the residences were connected to the
Gastonia public water supply as part of the RA to execute the provisions of the Record of
Decision (ROD) for the site. The locations of the residences connected to the Gastonia public
water supply and the carbon filtration units are presented in Figures 1-2 and 1-3, respectively.

1.3 GROUNDWATER CONTAMINANT DESCRIPTION
This section describes the potential source area of the contamination, current knowledge of the
groundwater plume, and the extent of the plume.
l.3,1 Contaminant Source Area
According to preliminary site investigation reports (see RI Report, 1998, for summary), a
groundwater sample was collected on 31 March 1990 from a supply well within the Cedar Oak
Park subdivision by Gaston County Environmental Health representatives as part of a routine
sampling procedure in accordance with "Community Well Rules." Analysis of the sample
revealed concentrations of TCE (34.9 micrograms per liter [µg/11), tetrachloroethene (PCE) (23.7
µg/1), and chloroform (9.2 µg/1). Analytical results for a confirmation sample collected from this
well on 17 April I 990 were similar to the original sample. Groundwater samples collected from
three nearby private wells in May 1990 by the Gaston County Health Department indicated that
the groundwater was contaminated with TCE. The highest concentration of TCE (IO 1.4 µg/1)
was detected in a sample collected from the private well located at 2419 Davis Park Road (see
Figure 1-4), 200 feet south of the Davis Park Auto Repair facility (located at 2307 Davis Park
Road). The current EPA Drinking Water Maximum Contaminant Level (MCL) for TCE and
PCE is 5 µg/1. Current State (North Carolina Department of Environment and Natural Resources
INCDENRI) MCLs for TCE and PCE are 2.8 µg/1 and 0.7 µg/1 respectively.
The Environmental Services Division of EPA collected groundwater samples from the
contaminated wells along Davis Park Road and within the Cedar Oak Park subdivision in July
1990. TCE was detected at concentrations of 82 µg/1 and 31 µg/1 in groundwater sampled from
the private well located at 24 I 9 Davis Park Road and a Cedar Oak Park subdivision well (2719
Davis Park Road), respectively.

Revision: 0
Date: May 2006
Additional investigations and groundwater sampling events pnor to the initiation of the RI
continued to reveal levels of contaminants above State and Federal drinking water standards.
Investigation activities focused on a possible source location(s). Several potential sources of the
contamination at the Davis Park Road TCE Site were reviewed. Consideration of proximity,
regional and local groundwater flow directions, and groundwater sample analytical data
indicated that the Davis Park Road Auto Repair facility was the most likely contaminant source
at the Davis Park Road TCE Site (NCDENR Site Inspection. I 993).
As a result of these findings and in an effort to further define the source area for the water supply
well contaminants, environmental assessments were conducted, including the Site Inspection
Addendum (SI) (May 1993), Expanded Site Investigation (ES!) (May 1994), and RI (1996-
1998). The RI report summarizes the source investigation as follows: " ... according to data
generated from this and previous investigations, solvents such as PCE or TCE were introduced to
the environment from the property at 2307 Davis Park Road. This 'spill' migrated through the
vadose zone and the saprolite/partially weathered rock aquifer, and into the bedrock aquifer.
Once introduced into the environment, various biophysiochemical processes acted on the
contaminants to reduce the overall concentration as well as spread the contaminant mass
throughout various matrices. CuITently, the VOC contaminants, principally TCE and PCE.
appear to be present only within the bedrock aquifer and may continue to be drawn towards
active residential wells scattered throughout the site, specifically those wells to the west of Davis
Park Road."
1.3,2 Groundwater Plume Concentration and Extent
Five potential sources for water supply were identified in the Davis Park Road Area and
presented in the RI report. These include the following: City of Gastonia Public Water Supply
System: City of Gastonia Restricted Use Water Line: water supply well as part of a Community

Water System; a water supply well as part of a Private Well System, and private water supply
wells. Nine monitor wells were installed during completion of the RI (MW-IS, MW-ID, MW-
2S, MW-2D, MW-3S, MW-3D, MW-4S, MW-4D, and MW-5S). Following connection to City
Water in August 2000, seventeen private wells were abandoned, seven wells were converted into
monitor wells (CW-I through CW-7), and five residences were supplied with carbon filtration
units (2400 Skyland, 2419 Davis Park Road, 2717 Davis Park Road, 2839 Davis Park Road, and
2639 Springbrook). Figure 1-5 details the locations and water supply source of residences within
the vicinity of the Davis Park Road TCE Site updated to include activities completed as part of
the 1998 RI and as part of the 200 I RA to execute the provisions of the ROD for the site. A
summary of analytical data for the primary constituents of concern (PCE and TCE) detected in
groundwater sampled at the Davis Park Road TCE Site is presented in Table 1-1. Analytical data
was obtained for groundwater sampled after August 200 I from the 5 residences supplied with
carbon filtration units as part of the RA to execute the provisions of the ROD. This data is
included for PCE and TCE in Table 1-1. As described in the 1998 RI, the contaminant plume
was centered along Davis Park Road from Glenraven to Blackwood Creek and underlies areas
approximately 500 feet to the east and west of Davis Park Road.
1.4 SITE GEOLOGY AND HYDROGEOLOGY
The geologic profile across the site generally consists of a saprolite layer, underlain by a partially
weathered rock zone and the underlying fractured crystalline bedrock. The saprolite is a silty,
clay-rich, residual material derived from in-place weathering of rock. The saprolite zone appears
to be thickest (approximately 80 feet) near the ridge crest along the northern edge of the site,
thinning towards the lower elevations or stream valleys to approximately 20 feet in thickness. A
partially weathered rock layer typically underlies the saprolite, and ranges in thickness from
approximately 5 to 25 feet. This layer is composed of saprolite and fragments of weathered
bedrock. The bedrock is generally observed to be a fractured quartz biotite granite or granitic
gneiss.

February 2006 First Annual Sampling Event Report
Davis Park Road TCE Site
Section: 2

Date: May 2006
LONG TERM RESPONSE ACTION
The ROD for the Davis Park Road TCE Site (September I 998) states that following initiation of
a natural attenuation study, groundwater monitoring will be conducted on a quarterly basis for
three years and annually for the next 27 years. First year LTRA sampling results indicated a
continued decrease in contaminant concentrations as the plume migrates south and away from
the source area. Additionally, contamination concentrations did not vary significantly between
sequential quarters for any of the wells in the monitoring network. It was therefore
recommended that the sampling program be reduced from quarterly to semiannual monitoring
after the first year of the LTRA, then semiannually for the next 2 years. Results from the
qua11erly and semiannual sampling are summarized below. Results from the most recent
sampling (the first annual) event, are summarized in Section 3.0. Data obtained from the long
term groundwater monitoring are used to evaluate natural attenuation of contaminant
constituents within the bedrock aquifer plume at the Davis Park Road Site following provision of
city water to 64 residences in August 2000.
In April 2002 a baseline sampling event was conducted to establish current conditions and to
evaluate the need for installation of additional wells for the L TRA. Based on analytical results, it
was determined that natural attenuation was occurring at rates consistent with expectations, and
that the wells currently available for sampling were sufficient to evaluate natural attenuation in
long term performance monitoring. A Monitored Natural Attenuation Plan (submitted to EPA in
October 2002) was developed to include sampling a network of bedrock wells for VOCs to
effectively characterize contaminant levels (VOCs) · in the bedrock aquifer within the
contaminant plume as well as the surrounding area for the potential migration of contaminants
from within the existing groundwater plume.

Revision: 0
Date: May 2006
The eighteen bedrock wells initially included for groundwater sampling in each L TRA
monitoring event included four bedrock monitor wells installed in December 1997 (MW-I
through MW-4), the five private wells provided with carbon filtration units in August 2000
(MW-5 through MW-9), two community wells located west of Davis Park Road (MW-10 and
MW-11), four converted wells (MW-12 through MW-15), and three private wells (MW-16
through MW-18). Monitor wells MW-2, MW-5, MW-6, MW-9, MW-12, MW-15. MW-16,
MW-17, and MW-18 were selected to provide groundwater quality information within the
contaminant plume. The remaining monitor wells (MW-I. MW-3, MW-4, MW-7, MW-8, MW-
10, MW-11, MW-13, and MW-14), located outside the contaminant plume, were selected to
provide evidence of potential contaminant migration.
Beginning with the first year fourth quarter sampling event, MW-13 was removed from the
sampling network arid replaced with MW-19, located south of the site, just outside the
contaminant plume. Additionally, following the fourth quarter sampling event. two bedrock
wells were installed west of the plume to monitor the area between the plume and the currently
pumping community wells to the west of the site (MW-IO and MW-I I). These wells were
incorporated into the monitoring network and are designated MW-20 and MW-21. Figure 2-1
provides the locations of the monitor wells in the sampling network. Table 2-1 provides
monitored natural attenuation sample designations cross-referenced with addresses and former
designations.
2.1 QUARTERLY AND SEMIANNUAL GROUNDWATER MONITORING
The purpose of L TRA groundwater monitoring is to verify the following:
• Natural attenuation is occurring at rates according to expectations,
• No changing conditions arise that might reduce efficacy of this remedy,
• The continued absence of toxic and/or mobile transformation products.

• The plume is not expanding,
• There is no impact downgradient,
• There arc no new releases, and
• Attainment of remediation objectives.
The samples are collected in accordance with the following documents:
• Final Monitored Natural Attenuation Plan, dated October 2002,
• U.S. Environmental Protection Agency Science and Ecosystem Support Division (EPA-
SESD), Region 4, revised Environmental Investigation Standard Operating procedure and
Quality Assurance Manual (EISOPQAM), May I 996, and
• U.S. Geological Survey, User's Guide for Polyethylene-Based Passive Diffusion Bag
Samplers to Obtain Volatile Organic Compound Concentrations in Wells, 2001.
All samples are analyzed by laboratories in the Contract Laboratory Program (CLP). Samples are
analyzed for VOCs using EPA Method 8260.
2.2 FIRST YEAR OUARTERL Y LTRA SAMPLING EVENTS (2002/2003)
The first quarter sampling event, performed in April 2002, was originally developed as the
baseline event to establish current conditions and to evaluate the need for installation of
additional wells. Based on analytical results, it was determined that the wells then available for
sampling were sufficient to evaluate natural attenuation in long term performance monitoring.
Thirteen of the 18 wells selected for the sampling network and two additional wells were
sampled in the baseline-sampling event. All 18 wells in the LTRA sampling network were
sampled during the second and third quarter sampling events, performed in September and
December 2002, respectively.

Revision: O
Date: May 2006
During the fourth quarter sampling event, performed in March 2003, monitor well MW-13 could
not be sampled due to hostile property owners. The ,residence at 2833 Davis Park Road was
sampled instead, and incorporated into the monitor well network as MW-19. BecaL1se the
owners of the property were not willing to allow samplers to pass through their yard to access the
well, and because VOCs have not historically been detected in groundwater sampled from the
well, MW-13 was removed from the monitor well network permanently and replaced with MW-
19. All of the remaining 17 wells in the LTRA sampling network were sampled during the fourth .
. quarter sampling event.
Depth to water was recorded where possible (MW-I through MW-4, MW-12 through MW-15)
prior to sampling. Field parameters (pH. specific conductivity, temperature, dissolved oxygen,
oxidation reduction potential, and turbidity) were also recorded. The potentiometric maps for the
bedrock aquifer in first through fourth quarter LTRA sampling events indicated a groundwater
flow direction in the bedrock aquifer ranging from south to east across the site, with the strongest
component of flow to the southeast. This is consistent with previously reported data.
TCE and PCE concentrations detected in groundwater during the first through fourth quarter
sampling events suggest the contaminant plume is migrating slightly to the west and also
southeast. Concentrations were significantly less than those detected in 1990 for wells in the
northern portion of the plume. However, concentrations increased slightly in wells to the west
and southeast. Levels were consistent with a naturally attenuating plume that is shifting due to
pumping ( community wells on Skyland Drive and Briar Oak Drive located west of the site) and
to a groundwater flow direction trending to the southeast and Blackwood Creek. First through
fourth quarter analytical results are detailed in the LTRA Second, Third, and Fourth Quarter
Sampling Event Reports submitted to EPA in January, April, and June 2003. respectively.

2.3 SEMIANNUAL LTRA SAMPLING EVENTS (AUGUST 2003/FEBRUARY
2004/AUGUST 2004/FEBRUARY 2005)
Following the first year of quarterly sampling at the Davis Park Road Site, two additional
monitor wells were installed between the contaminant plume and the cmTently pumping
community wells MW-10 and MW-1 l. These wells, designated MW-20 and MW-21, were
incorporated into the LTRA monitor well network and sampled in August 2003, February 2004,
August 2004, and February 2005.
During these sampling events, the nine wells in the monitor well network that could be accessed
at the well-head were sampled using both low-flow technology and passive diffusive bag (PDB)
samplers. PDBs were evaluated and found to be an effective sampling alternative to the low-
flow method of sampling. PDBs were subsequently recommended as the select method for
sampling monitor wells that can be accessed for the remainder of the L TRA.
PDBs are polymer membranes filled with deionized water that are placed at select depths into the
groundwater column. Organic analytes permeate the membrane, diffusing deionized water out of
the device until equilibrium is reached with the surrounding groundwater. Advantages to using
PDBs verses traditional sampling methods include decreased spending on labor and equipment
and elimination of containing and disposing of sampling purge and decontamination fluids.
The potentiometric maps for the bedrock aquifer based on the semiannual LTRA sampling
events indicated a groundwater flow direction in the bedrock aquifer ranging from south to east
across the site, with the strongest component to the southeast, consistent with previous reports.
However, the addition of three new survey points (MW-15, MW-20, and MW-21) provided data
indicating that to the north of the site there is also a west to southwest component to the
groundwater flow. This flow component was attributed in pait to the actively pumping
community wells to the west of the site.

TCE and PCE concentrations detected in groundwater during the semiannual L TRA sampling
events continued to suggest the contaminant plume is migrating slightly to the west and also to
the south. TCE and PCE levels were consistent with a naturally attenuating plume that is
shifting slightly due to pumping and to a groundwater flow direction trending to the southeast.
The semiannual analytical results are detailed in the LTRA August 2003, Febrnary 2004, August
2004, and February 2005 Semiannual Sampling Event Reports submitted to EPA in December
2003, April 2004, November 2004, and May 2005 respectively.
Following the February 2005 sampling event, the owner of monitor well MW-14, located north
and upgradicnt of the current contaminant plume, requested permission to abandon the monitor
well on her property at 2403 Davis Park Road. Because samples from this well had not contained
COCs at levels exceeding the repo1ting limit since L TRA sampling began in September 2002, it
was agreed this well was no longer necessary to the monitor well network, and MW-14 was
abandoned and removed from the L TRA monitoring program.

FEBRUARY 2006 ANNUAL LTRA SUMMARY
Section 3 of this report summarizes activities conducted as part of the first annual sampling event
for the Davis Park Road TCE L TRA.
3.1 GROUNDWATERSAMPLING
3.1.1 Monitor Well Sampling Procedures
WESTON mobilized to the site the week of 7 February 2006. With the exception of one location,
MW-6, which could not be accessed, groundwater samples were collected from all wells in the
monitor well network from 7 February through 8 February 2006. In order to ensure their
location during future sampling events, all LTRA sampling points were logged with a Global
Positioning System (GPS) unit during this sampling event. The results from the GPS survey are
presented in Table 3-1.
PDB samplers were used to sample the eight monitor wells that can be directly accessed at the
Davis Park Road Site (MW-I through MW-4, MW-12, MW-15, MW-20, and MW-21). Hanger
assemblies, to which PDBs in protective mesh were attached, were placed at selected depths
along polypropylene ropes for each of the accessible wells during the February 2005 sampling
event (see Table 3-2).
During the February 2006 sampling event, each of the PDBs was pulled and pierced with a small
discharge tube which allowed the transfer of the groundwater to 40 milliliter (ml) septa vials that
contained hydrochloric acid preservative. After the sampler bag was disconnected from the rope.

Revision: 0
Date: May 2006
a new filled PDB sampler was attached and placed downhole at the same depth. The PDB will
then equilibrate with the surrounding groundwater for the next annual sampling event.
All samples were placed on ice pnor to shipment under CLP protocol to EPA -SESD
Laboratory, located in Athens, GA, for VOC analysis using EPA Method 8260.
3.1.2 Community and Private Well Sampling Procedures
Community wells MW-10 and MW-11 and private wells MW-5 through MW-9 and MW-16
through MW-19 were purged and sampled from the in-situ pumping system, but prior to any
filter mechanism that may have been in place. Wells were purged at approximately I gallon per
minute for a period of approximately 15 minutes. Specific conductivity. pH. temperature,
dissolved oxygen, and oxidation/reduction potential were measured approximately every 5
minutes during the purge process. Purging continued until parameters were stable for three
successive readings, and samples were collected directly into pre-labeled, pre-preserved 40-ml
glass vials. All samples were placed on ice prior to shipment under CLP protocol to EPA -
SESD Laboratory, located in Athens, GA. for VOC analysis using EPA Method 8260. Water
quality data sheets and field log notes are provided in Appendix A.
3.1.3 Field Quality Assurance/Quality Control Samples
One rinse blank, one trip blank, and one duplicate sample were collected during the sampling
event. The rinse blank was collected by pouring laboratory-grade deionized water into the PDB
and collecting directly into pre-labeled. pre-preserved 40-ml glass vials. One trip blank was
collected by pouring lab-grade deionized water directly from the deionized water container into
the sample vial prior to commencing field activities. The trip blank was stored with collected
samples throughout the sampling event. The duplicate sample was collected from well MW-I 5,

using two PDB samplers. All samples were placed on ice prior to shipment under CLP protocol
to EPA -SESD Laboratory, located in Athens, GA, for VOC analysis using EPA Method 8260.
All samples were analyzed for VOCs using EPA Method 8260.
Analytical results for the QA/QC samples are summarized in Table 3-2. No VOCs were detected
in the trip, rinsate, or field blank samples. Cyclohexane, a common laboratory contaminant, was
detected at a low concentration (l.4 µg/1) in the original sample MW-15 but not in the duplicate.
All other detected constituents were reported at the same concentration in both the original and
duplicate samples.
3.2 GROUNDWATER ELEVATION
WESTON collected water level measurements referenced to the top of the well casmg for
monitor wells MW-I through MW-4, MW-12, MW-15, MW-20 and MW-21 on 7 and 8
Febmary 2006 (Table 3-3). Depth to water was measured using an electronic water level meter.
The water level probe and tape were decontaminated prior to each measurement. Figure 3-1
provides a potentiometric surface map of the bedrock aquifer.
As in the previous two semiannual sampling events, data from monitor well MW-21 was
considered anomalously high, and not included for development of the potentiometric surface
map. As in previous sampling events, the water level in this well was carefully evaluated and
measured at various times during the event to confirm findings and to evaluate for potential
fluctuations. The water level remains anomalously high relative to the other monitor wells in the
well network. It is likely the well is screened in a low yield fracture that equilibrated ovenime to
the current elevation. The measurement was agat11 not included for development of the
potcntiometric surface map.

3.3 GROUNDWATER ANALYTICAL RESULTS
3.3.1 Groundwater Samples
February 2006 First Annual Sampling Event Report
Davis Park Road TCE Site
Section: 3
Revision: 0
Date: May 2006
Consistent with previous L TRA sampling events. TCE and PCE were the only YOC constituents
lo exceed the ROD Performance Standards in groundwater samples collected during the
February 2006 Annual L TRA sampling event. TCE and/or PCE were detected in groundwater
sampled from 7 of the 18 wells sampled. The Performance Standard of 2.8 µg/1 (TCE) and/or I
µg/1 (PCE) was exceeded in 5 groundwater samples. TCE exceeded the ROD Performance
Standard in the following samples: MW-2 (2.9 µg/1), MW-9 (12 µg/1), MW-15 (40 µg/1) and
MW-17 (13 µg/1). PCE exceeded the ROD Performance Standard in the following samples:
MW-2 (2.6 µg/1), MW-17 (7.4 µg/1), and MW-18 (4.2 µg/1). Monitor well MW-6. which has
historically exceeded the ROD Performance Standards for TCE and PCE, could not be accessed
for sampling during this event.
Laboratory analytical results for first year through fourth year L TRA sampling events arc
summarized in Table 3-4. The February 2006 analytical results are summarized graphically in
Figures 3-2 and 3-3 for TCE and PCE, respectively. Laboratory analytical reports are included in
Appendix B.
The highest TCE concentration (40 µg/1) was detected in groundwater sampled from monitor
well MW-15, located at the west central portion of the site. The second highest TCE
concentration (13 µg/1) was detected in groundwater sampled from monitor well MW-17, located
on the southern side of the site. The highest PCE concentration (7.4 µg/1) was also detected in
groundwater sampled from MW-I 7. The second highest PCE concentration (4.2 µg/1) was
detected in groundwater sampled from MW-18, localed immediately north and west of MW-17.

February 2006 First Annual Sampling Event Report
Davis Park Road TCE Site
Section: 3
Revision: O
Date: May 2006
Detections of TCE and PCE in groundwater sampled in February 2006 at the Davis Park Road
site were similar to concentrations detected in previous L TRA groundwater sampling events.
PCE and TCE concentrations in groundwater have generally remained stable or decreased at
sampling locations during the first four years of the Davis Park Road TCE Site LTRA. There are
two areas where PCE and TCE concentrations continue to exceed guidance concentrations. One
area is downgradient of the original groundwater contaminant plume center at the southern and
eastern portion of the site. The second area is located in the central and western portion of the
site. PCE and TCE concentrations in both these locations remain lower than historical detections
in the former plume center.
PCE and TCE, previously detected in trace concentrations m groundwater sampled from
locations west and north of the former plume boundary (MW-10, MW-l l, MW-20, MW-21)
have not been detected in any of these monitor wells since February 2004. Pumping from
community wells in this area does not appear to be causing migration of the contaminant plume
in this direction. Groundwater elevations, discussed in Section 3 .2, support this conclusion.
MTBE was detected in the two following samples: MW-3 (l 7 µg/1) and MW-20 (99 µg/1).
Groundwater samples collected from these monitor wells, both located adjacent to the 2400
Skyland residence, have historically contained MTBE concentrations at similar levels. MTBE
was not detected in any other groundwater samples collected during the February 2006 sampling
event. and does not appear to be related to the TCE plume at the Davis Park Road site. MTBE
concentrations have generally remained stable during the first four years of LTRA. The ROD
Performance Standard of 200 µg/1 for MTBE has not historically been exceeded.

SECTION 4
February 2006 First Annual Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: O
Date: May 2006
CONCLUSIONS AND RECOMMENDATIONS
4.1 LTRA RESULTS SUMMARY
The source for the TCE/PCE contamination in groundwater at the Davis Park Road TCE Site is
depleted or removed based on groundwater sampling results reported from the time of
contaminant discovery (1990) to the current February 2006 LTRA Annual sampling event.
Water sampled from wells north of Skyland Drive (MW-5) and in the Cedar Oak Circle
Subdivision (MW-12) contained concentrations of between 44 and 134 µg/1 TCE and up to 24
µg/1 PCE when sampled in 1990. Groundwater sampled from MW-5 and MW-12 in February
2006 did not contain concentrations of TCE or PCE above the ROD Performance Standards (2.8
µg/1 and I µg/1, respectively). Figures 4-1 through 4-2 graphically depict the decreased levels of
COCs in these wells.
TCE and PCE concentrations in all wells have generally decreased over time, with the exception
of the areas southwest central and south southeast of the site. Groundwater sampled from
monitor well MW-15. located southwest of the source area, contained 40 µg/1 TCE during the
current sampling event. Excluding this groundwater sample, the maximum TCE concentration
for groundwater samples collected this sampling event is 13 µg/1 in groundwater sampled from
well MW-I 7. The maximum PCE concentration is 7.4 µg/1, also detected in groundwater
sampled from well MW-17. Monitor well MW-17 is located on the southeast portion of the site
approaching Blackwood Creek, suggesting groundwater contamination continues to attenuate as
it migrates toward this natural groundwater discharge area.

February 2006 First Annual Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: 0
Date: May 2006
Concurrently with the migration toward Blackwood Creek, the August 2003 and February 2004
sampling data indicated a contaminant migration southwest of the source area, as evidenced by
groundwater elevations and the detection of trace TCE and PCE concentrations in groundwater
sampled from the western side of the site. However, the August 2004, February 2005 and
February 2006 sampling results show no detections of TCE or PCE on the west side of the site.
Although pumping of groundwater has been discontinued over most of the Davis Park Road TCE
Site area, two community wells (MW-10 and MW-11) are currently still active near Briar Oak
Drive, west of the site. Community well MW-I 0, located on Skyland Drive, supplies between 30
and 40 people, and MW-I 1, located on Briar Oak Drive, supplies approximately nine people,
according to Mr. Doc Thompson of the Gaston County Health Department. It was thought that
pumping of these wells might facilitate migration of. groundwater contaminants in a westerly
direction. Monitor wells MW-20 and MW-21 were installed in the area between the contaminant
plume and the community wells, to monitor for potential migration of the contaminant plume.
These wells are located between MW-15 (the well with the highest TCE concentration) and the
ctnTently pumping community wells. However, the data from sampling wells MW-20 and MW-
21 do not currently indicate that COCs in groundwater are migrating toward the pumping wells.
Additionally, groundwater levels in MW-21 indicate an upward gradient to the bedrock aquifer
in this area. This may provide a natural barrier to movement of the contaminant plume in this
direction.
Monitor well MW-15 is located southwest of the source area, with Davis Park Road to the east
and well MW-9 to the southwest. Concentrations ofTCE detected in monitor well MW-15 have
fluctuated between 36 µg/1 and 50 µg/1 since September 2002 (see Figure 4-3), similar to
historical levels detected in groundwater sampled from converted community well MW-12
(located east and downgradient of the source area, in the former plume center) (see Figure 4-2).
TCE concentrations fluctuated between approximately 30 and 50 µg/1 in groundwater sampled
from MW-12 from 1990 through 1998. TCE was detected at 2.1 µg/1 in groundwater sampled

Section: 4
Revision: O
Date: May 2006
from MW-12 during this groundwater sampling event. TCE concentrations 111 groundwater
sampled from well MW-9 (currently supplied with a carbon filtration unit) have fluctuated since
August 2000 when first sampled, but have ranged from 6.8 µg/1 (detected in November 200 I) to
16 µg/1 (detected in March 2003) (see Figure 4-4). These levels are similar to groundwater
samples collected from wells MW-17 and MW-18, located further south and downgradient of the
source area toward Blackwood Creek (see Figures 4-5 and 4-6). Results are consistent with an
attenuating plume migrating from the former sources area.
4.2 CONCLUSIONS
TCE and PCE concentrations continue to decrease in the contaminant plume as it migrates south
and away from the former source area. No additional degradation products of these two
constituents were detected at any significant level in any of the groundwater samples collected
historically or during the L TRA quarterly/semiannual sampling events. Graphs of historical TCE
and PCE concentrations from key monitor wells are presented as Figures 4-1 through 4-6.
Figures 4-1 and 4-2 shows the decline of COCs in groundwater sampled near the original plume
center from levels well above EPA MCLs to levels either approaching or consistently below the
MCLs and ROD Remediation Goals from 1990 through the current sampling event. Figures 4-3
through 4-6 illustrate the fluctuating COC levels in wells located at and downgradient of the
current plume center. These values are significantly lower than levels detected at the plume
center in the early 1990s, following discovery of the plume. Figures 4-1 through 4-6 support the
groundwater concept model (EPA Memorandum. 25 September 2000) that the primary
mechanism for the observed natural attenuation of the TCE plume at Davis Park Road is dilution
as contamination essentially flushes through the bedrock aquifer. The analytical results are
consistent with the proposed cleanup time of 13 years (by the year 2017) to attain EPA MCLs.

February 2006 First Annual Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: 0
Date: May 2006
In conclusion. the February 2006 first Annual LTRA sampling event results confirm that natural
attenuation is occurring at rates according to expectations, no changing conditions have arisen
that might reduce efficacy of this remedy, no toxic and/or mobile transformation products are
being produced, the plume is not expanding, there is no impact downgradient, there 1s no
evidence of a new release, and source area wells have attained remediation objectives.
4.3 RECOMMENDATIONS
Analytical results from quarterly, semiannual, and annual sampling of the monitor well network
at the Davis Park Road Site indicate decreasing levels of COCs. Perimeter wells located outside
the plume continue to monitor for potential migration of plume constituents. PDBs continue to
provide representative samples of the principle COCs in groundwater at the Davis Park Road
Site, while at the same time being more easily implemented and cost-effective than low-flow
sampling methods. It is recommended that annual sampling be continued for the duration of the
LTRA.
Access to monitor well MW-6 has been prevented by the owner for three consecutive sampling
events. The monitoring point is within the current contaminant plume and provides information
that helps characterize the plume. The current home owners did not request access to city water
and were provided with a carbon filtration unit for their drinking water. It is recommended that
the owners be contacted during the coming year to request their formal approval for inclusion
within the LTRA sampling network. If approval is refused, monitor well MW-6 will be removed
from the monitoring program. Because there are monitoring points up-and down-gradient of
this well, it will not be necessary to replace this sampling point. The plume will continue to be
characterized without the additional information provided by data collected from sampling of
this well.
