INTRODUCTION
February 2004 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 1
Revision: 0
Date: April 2004
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) 31 the Davis Park
Road Trichloroethcne (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 138-RALR-04PN. The
current LTRA 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.
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 Cmolina. 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 groundw.ater 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.

February 2004 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 1
Revision: O
Date: April 2004
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 Sec1ion 1.3.2.
Al lhe lime of lhe discovery of conlaminants in the groundwater (March 1990), a majority of lhe
residences throughoul the sile were supplied water by residential water supply wells. As a result
of the continued migration of the plume, groundwater supplying many of lhese residential waler
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 lo reduce lhe polential health threat from the contaminants. In 1996, many of lhe houses
within the Hedgewood Circle neighborhood, which borders the northern edge of the site, were
connected to the public water supply. In late 1997 and early 1998, 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 1998 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 lhc 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.

1.3.1 Contaminant Source Area
February 2004 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 1
Revision: O
Date: April 2004
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 fµg/1]), tetrachloroethene (PCE)
(23.7 ftg/1), and chloroform (9.2 µg/1). Analytical results for a confirmation sample collected
from this well on 17 April 1990 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 I .4 µg/1) was detected in a sample collected from the private well located at 2419 Davis Park
Road, 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 an·d Natural Resources
[NCDENR]) MCLs for TCE and PCE are 2.8 µg/1 and 0.7 µg/1 respectively. Street address
locations are shown in Figure 1-4.
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 (27 I 9
Davis Park Road), respectively.
·-.
Additional investigations and groundwater sampling events prior 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, 1993).
As a result of these findings and in an effon 10 further define the source area for the water supply
well contaminants, environmental assessments were conducted, including the Site Inspection
Addendum (SI) (May 1993), Expanded Sile Investigation (ESI) (May 1994), and RI (1996-
1998). The RI report summarizes the source investigation as follows: " ... according lo data
generated from this and previous investigations, solvents such as PCE or TCE were introduced lo
the environment from the property al 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 lo reduce the overall concentration as well as spread the contaminant mass
throughout various matrices. Currently, the VOC contaminants, principally TCE and PCE,
appear to be present only within the bedrock aquifer and may continue lo 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 waler 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-SS). 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 tile 5 residences supplied with
carbon filtration units as pa11 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.

SECTION 2
February 2004 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 2
Revision: 0
Date: April 2004 ·
LONG TERM RESPONSE ACTION
The ROD for the Davis Park Road TCE Site (September 1998) 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 s·ampling program be reduced from quarterly to semiannual monitoring.
Results from the second semiannual event are summarized in Section 3.0. Data obtained from the
long term groundwater monitoring will be 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 LTRA. 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.

February 2004 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 2
Revision: O
Date: April 2004
The eighteen bedrock wells initially included for groundwater sampling in · each L TRA
monitoring event included four bedrock monitor wells installed in December I 997 (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-I I), four converted wells (MW-12 through MW-I 5), and three private wells (MW-I 6
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-I I, 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-I 3 was removed from the
sampling network and replaced with MW-19, located south of the site, just outside the
contaminant plume. Additionally, following the fourth quarter sampling event, two bedrock
weUs 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-11). ll1ese wells were
incorporated into the monitoring network and are designated MW-20 and MW-21. Figure 2-1
provides the locations of the monitor well sampling netw·ork. Table 2-1 provides monitored
natural attenuation sample designations cross-referenced with addresses and former designations.
2.1 OUARTERL Y AND SEMIANNUAL GROUNDWATER MONITORING
The purpose of quarterly and semiannual groundwater monitoring is to verify the following:
• That natural attenuation is occurring at rates according to expectations,
• No changing conditions arise that might reduce efficacy of this remedy,
• ll1e continued absence of toxic and/or mobile transformation products,
• Verification that the plume is not expanding,

• Verification that there is no impact downgradient,
• Detection of any new releases, and
• Verification of 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 1996, and
• U.S. Geological Survey, User's Guide for Polyethylene-Based Passive Diffusion 13ag
Samplers to Obtain Volatile Organic Compound Concentrations in Wells, 2001.
All samples are analyzed by laboratories in the Contract Laboratory Program. 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 currently available
for sampling were sufficient to evaluate natural attenuation in long .term performance
monitoring. Thirteen of the I 8 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.
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-I 9. Because the current
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 map 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.

Davis Park Road TCE Site

2.3 SEMIANNUAL LTRA SAMPLING EVENT (AUGUST 2003)
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 currently pumping
community wells MW-IO and MW-11. These wells, designated MW-20 and MW-21, were
incorporated into the L TRA monitoring well network and sampled in August 2003, along with
the remaining I 8 monitor wells previously included in the sampling program. Also during this
sampling event, passive diffusive bag (PDB) samplers were placed in seven monitor wells
(MW-I through MW-4, MW-12, MW-14, and MW-15) two weeks prior to the August 2003
sampling event. The PDB samplers were pulled and sampled concurrently with low-flow
sampling to evaluate PDBs as an effective sampling alternative for the remaining duration of the
LTRA. Sampling procedures otherwise were identical to previous quarterly sampling events
described in Section 2.2.
The potentiometric map for the bedrock aquifer in the first semiannual sampling event 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· previously reported data.
However, the addition of three new survey points (MW-15, MW-20, and MW-21) provided data
indicating that there is also a west to southwest component to the groundwater flow. This flow
component may be attributed to the actively pumping community wells to the west of the site.
TCE and PCE concentrations detected in groundwater during the August 2003 semiannual
LTRA sampling event continued to suggest the contaminant plume is migrating slightly to the
west and also to the south. Trace TCE and PCE concentrations were confirmed in private well
MW-19, which was added to the monitor well network during the fourth quarter sampling event.
MW-19 is located at the south-southwestern portion of the site. Additionally, TCE was detected
in newly installed monitor wells MW-20 and MW-21 at concentrations below the ROD

Remediation Goal. MW-20 and MW-21 are located between the contaminant plume and the
actively pumping community wells west of the site. The semiannual analytical results are
detailed in the LTRA August 2003 Semiannual Sampling Event Report submitted to EPA in
December 2003.
Analytical results for PDB samples generally corresponded well with the results of the samples
collected using low-flow technology. The average relative percent difference. for COCs
(excluding MTBE) detected above the reporting limit using low-flow and the PDB sampler
placed closest to low-flow intake depth was 18 percent. All constituents detected above the
reporting limit in the low-flow samples were also detected in the PDE sampler at similar
concentrations, and all reported detections exceeding the remedial goal in the low-flow sampler
were also detected at concentrations exceeding the remedial goal in the PDE sampler. Because
the PDBs 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 was recommended that PDBs be used to sample accessible wells in
the monitor well network for the duration of the L TRA.

SECTION 3
FEBRUARY 2004 LTRA SUMMARY
Section 3 of this report summanzes activities conducted as part of the second semiannual
sampling event for the Davis Park Road TCE LTRA.
3.1 GROUNDWATERSAMPLING
3.1.1 Monitor Well Sampling Procedures
WESTON mobilized to the site the week of 3 February 2004. Groundwater samples were
collected from the 20-monitor well network from 3 February through 5 February 2004. During
the February 2004 sampling event, recently installed monitor wells MW-20 and MW-21 were
sampled using low-flow techniques and also with PDB samplers. A comparison of the low-flow
samples with the PDB samples will be discussed in Section 3.4.2.
Low-flow groundwater samples were collected in accordance with Puls and Barcelona (1996)
Low-Flow (Minimal Drawdown) Groundwater Sampling Procedures published by the EPA
Superfund Technology Support Center for Ground Water using a MicroPurge bladder pump.
Water level and field parameter measurements (pH, specific conductivity, temperature, dissolved
oxygen, and oxidation/reduction potential) are summarized in Table 3-1. All downhole
equipment was decontaminated prior to use in each well. Pump intake was lowered to well
screen depth, and the well was micro-purged until field parameters stabilized. Laboratory
samples for YOC analysis were then collected in pre-labeled, pre-preserved sample bottles.
Bottles were capped appropriately, placed in a Ziploc-type bag, and stored in an ice-cooled

container prior to shipment to the CLP designated laboratory, A4 Scientific located m The
Woodlands, Texas.
PDB samplers were used to sample the nine monitor wells that can be directly accessed at the
Davis Park Road Site (MW-I through MW-4, MW-12, MW-14, MW-15, MW-20, and MW-21).
The PDBs, polymer membrane bags, were filled with laboratory grade deionized water, attached
to a polypropylene rope connected to the well cap, and lowered downhole 9 January 2004 at
select depths (see Table 3-2). The samples were collected no sooner than two weeks later by
pulling the PDB samplers from the wells, and decanting them into pre-labeled, pre-preserved
sample bottles. After the sampler bag was disconnected from the rope, a new filled PDB sampler
was attached and placed downhole at the same depth, to equilibrate with the surrounding
groundwater for the next sampling event (scheduled for June 2004).
3.1.2 Community and Private Well Sampling Procedures
Community wells MW-10 and MW-I I 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 as described above. Final readings for stabilized
parameters are summarized in Table 3-1.

February 2004 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 3
Revision: O
Date: April 2004
3.1.3 Field Quality Assurance/Quality Control Samples
One rinse blank, one PDB field blank, one duplicate, and one trip blank were collected during
the sampling event. The rinse blank was collected by pouring laboratory-grade deionized water
over the low-flow sampling equipment. The PDB field blank was collected by pouring
laboratory-grade deionized water into an unused PDB sampler prior to collecting the water in the
sample vial. The trip blank was collected by pouring lab-grade deionized water directly from a
container into the sample vial. A certificate of analysis for the deionized water is included in
Appendix B. 1l1e trip blank was stored with collected samples throughout the sampling event.
The duplicate sample was collected from well MW-15, using two PDB samplers. All samples
were analyzed for VOCs using EPA Method 8260.
Analytical results for the QNQC samples arc summarized in Table 3-3. Chloromethane and
toluene were detected in the rinse, field, and .trip blanks at estimated concentrations below the
reporting limit. Chloromethane was detected in groundwater samples collected from monitor
wells MW-I, MW-4, MW-5, MW-6, MW-9, and MW-17 at estimated concentrations below the
reporting limit. Toluene was detected in the low-flow and PDB samples collected from monitor
well MW-20 at estimated concentrations below the reporting limit, and in the low-flow and PDB
samples collected from monitor well MW-21 at low levels above the reporting limit.
Chloromethane and toluene have been detected limitedly, in similar concentrations in
groundwater sampled from various wells at the Davis Park Road Site, and may be the result of
sample handling or conditions in the field. Analytical results have been flagged appropriately.
Duplicate results were within acceptable relative percent differences (<15%).for all constituents
identified at concentrations above the reporting limit, with the exception of methyl ethyl ketone.
Methyl ethyl ketone was detected at 9.3 µg/l in the original groundwater sample collected from
MW-15, but was not detected above the reporting limit (5.0 µg/1) in the duplicate sample. The

diffusion sampler method is not considered appropriate for sampling organic compounds with
high aqueous solubility, such .as methyl ethyl ketone, and the discrepancy in results indicates that
detections of this constituent should be considered suspect. 1,1-Dichloroethane and PCE were
detected below the reporting limit at an estimated concentration (below the reporting limit) in
both the original and duplicate groundwater samples.
3.2 GROUNDWATER ELEV A TION
WESTON collected water level measurements referenced to the top of the well casing for
monitor wells MW-I through MW-4, MW-12, MW-14, MW-15, MW-20 and MW-21 on the 3'd
and 4th of February 2004. Depth to water was measured using an electronic water level meter.
The water level probe and tape were decontaminated prior to each measurement. Field
measurements, including depth to water and water elevation, are summarized in Table 3-1.
Figure 3-1 provides a potentiometric surface map of the bedrock aquifer. Consistent with
previously reported data, groundwater flow direction in the bedrock aquifer appears to be
predominantly to the southeast, while to the north of the site, groundwater flow is also to the
west and southwest, towards the actively pumping community wells MW-10 and MW-I I.
3.3 GROUNDWATER ANALYTICAL RESULTS
3.3.1 Groundwater Samples
TCE and PCE were the only VOC constituents to exceed the ROD Remediation Goal in
groundwater samples collected during the February 2004 Semiannual L TRA sampling event.
TCE and/or PCE were detected in groundwater sampled from 12 of the 20 wells sampled. The
Remediation Goal of 2.8 µg/1 (TCE) and/or I µg/1 (PCE) was exceeded in seven groundwater
samples. TCE exceeded the ROD Remediation Goal in the following samples: MW-2 (4.0 µg/1),

MW-6 (3.0 µg/1), MW-9 (7.8 µg/1), MW-12 (3.5 µg/1), MW-15 (50 µg/1), MW-17 (17 µg/1), and
MW-18 (4.2 µg/1). PCE exceeded the ROD Remediation Goal in the following samples: MW-2
(1.3 µg/1), MW-6 (2.8 µg/1), MW-12 (1.4 µg/1), MW-17 (9.0 µg/1), and MW-18 (9.9 µg/1).
Laboratory analytical results for first year quarterly and first year semiannual LTRA sampling
events are summarized in Table 3-4. The 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 (50 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 ( 17 µg/1) was detected in groundwater sampled from monitor well MW-17, located
on the southern side of the site. The highest PCE concentration (9.9 µg/1) was detected in
groundwater sampled from MW-18, located near the south southeastern corner of the site. The
second highest PCE concentration (9.0 µg/1) was detected in groundwater sampled from MW-17,
also on the southern side of the site.
Although TCE and PCE concentrations increased slightly in the majority of wells sampled in I . February 2004 when compared to the August 2003 groundwater sampling results, PCE and TCE
concentrations in groundwater have generally remained stable or decreased at sampling locations

during the first two 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.
Trace concentrations of PCE were confirmed in groundwater sampled from locations west and
north of the former plume boundaries, where formerly these constituents were not detected (i.e.,

MW-3, MW-8, MW-10, and MW-11). Low levels ofTCE and trace PCE were also continned in
groundwater samples from monitor well MW-21 (located between the former contaminant plume
and the currently pumping community wells. No PCE or TCE was detected in monitor well
MW-20, located north of MW-21. Trace concentrations ofTCE and PCE continue to be detected
in private well MW-19 located at the south-southwestern portion of the site.
3.4 PASSIVE DU'FUSION BAG SAMPLERS
Low-flow techniques were used to sample the seven directly accessed wells at the Davis Park
Road Site for first through fourth quarters of the LTRA. Although minimizing purge water when
compared to traditional purges of at least 3 well volumes, the low-flow sampling technique still
produced approximately 55 gallons of purge water and decontamination fluids per sampling
event. Additionally, trnnsporting sampling equipment and contained purge water through
residents' yards, as well as staging, sampling, and arranging for transport and disposal of the
purge water following each sampling event presented new challenges with every sampling event.
It was recommended that PDB samplers replace low-flow groundwater sampling procedures for
the Davis Park Road TCE Site LTRA sampling events to maximize sampling efficiency,
minimize inconvenience to residents, and eliminate the need to contain, sample, and dispose of
purge water. During the August 2003 sampling event, the seven directly accessed wells were
sampled both using low-flow methods and PDB samplers. Results are discussed in the August
2003 Semiannual Sampling Event Report. Monitor wells MW-20 and MW-21 were installed
during the August sampling event and were not equipped with PDB samplers prior to
groundwater sampling. To verify that the PDB samplers are appropriate for LTRA monitoring in
these two wells, they were sampled using both low-flow methods and PDB samplers during the
February 2004 sampling event.

3.4.1 Methodology
February 2004 Semiannual Sampling Event Rep:,rt
Davis Park Road TCE Site
Section: 3
Revision: O
Date: April 2004
Both MW-20 and MW-21 were constructed with IO feet of open corehole at the base. In order to
assess potential stratification of COCs within the IO foot corehole, one PDB sampler was placed
in the top 5 feet and one PDB sampler was placed in the lower 5 feet of the open corehole of
each well (see Table 3-1 ). Assemblies for the PDBs were prepared prior to mobilization to the
site and stored in plastic bags. Stainless steel weights were attached to braided polypropylene
ropes that measured the length of each of the monitor wells. Hanger assemblies to·which PDBs
in protective mesh could easily be attached, were placed at th_e selected depths (calculated from
the bottom of the well) along each of the polypropylene ropes. Each well was provided a locking
cap to which the ropes could easily be attached. Three weeks prior to a scheduled sampling
event, PDBs were attached to the polypropylene ropes and placed down the two newly installed
bedrock monitor wells. Samplers were approximately 18 inches in length and filled with
approximately 200 milliliters of deionized water, sealed with no visible air bubbles, and
connected to the rope at_ the appropriate attachment.
Following a three-week period, each of the PDBs was pulled and pierced with a small discharge
tube which allowed the transfer of the groundwater to 40 milliliter septa vials that contained
hydrochloric acid preservative. Following collection of the PDB samples, a sample was
collected from the well using low-flow techniques as described in Section 3.1. I of this report.
All samples were placed on ice prior to shipment under CLP protocol to A4 Scientific, located in
The Woodlands, Texas, for VOC analysis using EPA Method 8260.

3.4.2 Comparison with Low-Flow Samples
February 2004 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 3
Revision: O
Date: April 2004
Laboratory analytical results for low-flow and PDB samples are summarized in Table 3-5.
Laboratory analytical reports are included in Appendix B. TCE, reported in groundwater
sampled from MW-I at levels below the ROD Remediation Goal of 2.8 µg/1, was the only COC
(other than MTB.E) detected at levels above the reporting limit in both low-flow and PDB
samples. PDB results from both depths sampled were identical (0.90 µg/1), indicating no
significant vertical stratification of COCs within the IO foot corehole interval. Additionally, the
relative percent difference between PDB and low-flow sample results for TCE is I. I, indicating
good correlation between PDB and low-flow sampling techniques.
PCE was detected in MW-21 at estimated concentrations below the reporting limit in the low-
flow and both PDB samplers, indicating good correlation between the two sampling methods,
even at these low concentrations. However, I, 1-DCE was detected in MW-21 at estimated
concentrations below the reporting limit in both PDB samplers, but not in the low-flow sample.
In general, when low level COCs (i.e., below the reporting limit) have been reported, they have
been detected in samples collected using both PDBs and low-flow methods. This exception may
indicate that this constituent is present at levels approximating the laboratory analytical detection
limit. With the exception of MTBE, no other COCs were detected in either the PDB or low-flow
samples collected from MW-20 and MW-21.
MTBE was detected in both MW-20 and MW-21, in low-flow and PDB samples. As with
previous sampling for this constituent, the PDB results equal approximately 25 percent of the
low-flow sample concentration. While PDBs will not provide replicate samples for low-flow
sampling of this constituent, MTBE has historically never occurred at levels exceeding the ROD
Remediation Goal. If MTBE concentrations were to suddenly rise significantly, it would likely

be the result of an unrelated source release, but the use of PDB samplers at the site would have to
be reconsidered.
Toluene, ethylbenzene, and xylenes were detected at estimated concentrations below the
reporting limit in groundwater sampled from MW-20 in the low-flow and both PDB samplers.
Ethylbenzene was also detected at an estimated concentration below the reporting limit in
groundwater sampled from MW-21 m the low-flow and both PDB samplers. Toluene was
detected in both the low-flow and PDB sampler for MW-21 at low levels, with an average
relative percent difference of 4.8. Xylenes were also detected in both the low-flow and PDB
sampler for MW-21 at low levels, with an average relative percent difference of 25.4. The low
level detection of these constituents in PDB and low-flow samples provides additional support
for the use of PDB samplers as a valid replacement for the low-flow sampling technique at this
site
Acetone and methyl ethyl ketone were detected in PDBs from both wells MW-20 and MW-21,
and also in the low-flow sample collected from MW-21. The diffusion sampler method is not
considered appropriate for accurately characterizing the presence of acetone and methyl ethyl
ketone, organic compounds with high aqueous solubiliiy. Both acetone and methyl ethyl ketone
were detected in all PDB samples. Their ubiquitous occurrence in these samples may be due in
part to laboratory contamination, either during analysis, or in preparation of the deionized water
used in the PDB samplers. However, neither constituent was detected in the trip, equipment, or
field blank. Levels detected are well below guidance concentrations (the NCDENR standards
are 700 µg/1 and 170 µg/1 for acetone and methyl ethyl ketone, respectively; acetone and methyl

significantly, it would likely be the result of an unrelated source release, and the use of PDB
samplers at the site would have to be reconsidered. Additionally, a different laboratory batch of

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 hased on groundwater sampling results reported from the time of
contaminant discovery ( 1990) to the current LTRA second semiannual sampling event in
February 2004. Water sampled from wells north of Skyland Drive (MW-5, MW-14) 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. Water sampled from these MW-5 and MW-
14 in February 2004 did not contain concentrations ofTCE or PCE at concentrations greater than
the ROD remediation goals of 2.8 ~tg/1 and I µg/1, respectively. Water sampled from MW-12
contained TCE at 3.5 µg/1 and PCE at 1.4 µg/1 (see figures 4-1 through 4-3).
Although TCE and PCE concentrations in some wells located south and west of the source area
have slightly increased, contaminant concentrations are significantly lower than those detected in
the source area at the time of the initial discovery in all but one well location. Groundwater
sampled from monitor well MW-I 5, located southwest of the source area, contained 50 µg/1 TCE
during the current sampling event. Excluding this groundwater sample, the maximum TCE
concentration for groundwater samples collected this sampling event is 17 µg/1 in groundwater
sampled from well MW-17. The maximum PCE concentration is 9.9 µg/1 in groundwater
sampled from well MW-I 8. Both wells MW-17 and MW-I 8 are located on the south and
· southeast portion of the site approaching Blackwood Creek, suggesting groundwater

contamination continues to attenuate as it migrates toward this natural groundwater discharge
area. Concurrently with the migration toward Blackwood Creek, there appears to be
contaminant migration southwest of the source area, as evidenced by groundwater elevations and
the detection of trace TCE and PCE concentrations in this area where previously there was none. ·
Although pumping of groundwater has been discontinued over most of the Davis Park Road TCE
Site area, two community wells (MW-10 and MW-! I) 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 I, located on Briar Oak Drive, supplies approximately nine people,
according to Mr. Doc Thompson of the Gaston County Health Department. Pumping of these
wells may facilitate migration of groundwater contaminants in a westerly direction. Two monitor
wells (MW-20 and MW-21) were recently installed and sampled in the area between the
contaminant plume and the community wells. Currently there are low levels of TCE and trace
levels of PCE in groundwater sampled from MW-21, the well located between MW-15 (the well
with the highest TCE concentration) and the currently pumping community wells. The data from
sampling of wells MW-20 and MW-21 should provide sufficient warning that COCs in
groundwater are migrating toward the pumping wells at concentrations exceeding the ROD
guidance concentrations, should this occur.
Monitor well MW-15 is located southwest of the source area, with Davis Park Road to the cast
and well MW-9 to the southwest. Concentrations of TCE detected in monitor well MW-15 have
nuctuated between 36 µg/1 and 50 ~tg/1 since September 2002, similar to historical levels
detected in groundwater sampled from converted community well MW-12 (located east and
downgradient of the source area) (see Figures 4-3 and 4-4). TCE conceillrations nuctuated
between ·approximately 30 and 50 µg/1 in groundwater sampled from M\v-12 from 1990 through
1998. TCE was detected at 3.5 µg/1 in groundwater sampled from MW-12 during .this
groundwater sampling event. TCE concentrations in groundwater sampled from well MW-9
(currently supplied with a carbon filtration unit) have nuctuated since August 2000 when first

sampled, but have ranged from 6.8 µg/1 (detected in November 2001) to 16 µg/1 (detected in
March 2003). These levels are similar to groundwater samples collected from wells MW-17 and
MW-I 8, located further south and downgradient of the source area toward Blackwood Creek
(see Figures 4-4 through 4-7).
4.2 CONCLUSIONS
TCE and PCE concentrations continue to decrease in the contaminant plume as it migrates south
and away from the 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 LTRA quarterly/semiannual sampling events. Graphs of historical TCE and PCE
concentrations from key monitor wells are presented as Figures 4-1 through 4-7. Figures 4-1
through 4-3 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 4-4 through 4-7 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 4-7 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 I 3 years (by the year 20 I 7) to altain
EPA MCLs. '· .
In conclusion, the February 2004 Semiannual LTRA sampling event results confirmed 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 is no
evidence of a new release, and source area wells have attained remediation objec1ivcs .
4.3 RECOMMENDATIONS
Analytical results from quarterly and semiannual sampling of the monilor 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. To reduce the cost and
streamline the L TRA sampling at the Davis Park Road Site, PDB samplers arc recommended to
replace low-flow sampling techniques in the newly installed wells MW-20 and MW-21. PDBs
provide representative samples of the principle COCs (PCE and TCE) in groundwater at the
Davis Park Road Site based on a comparison with low-flow samples. PDBs arc easier and less
expensive to deploy than sampling using a submersible pump. The total cost of assemblies for
PDBs for 9 wells was less than $1,500. Additional sampling costs will include only the
deionized water and the PDBs ($ I 5.00/ea) that are clipped on the existing assembly. PDBs at the
Davis Park Road Site can be installed in one day and sampled in one day for a total of two days
in the field. If the PDBs for the next sampling event are deployed immediately following sample
collection, sampling time in the field can be further reduced. By comparison, low-flow sampling
equipment (tubing, pump, field parameter instrnments) can cost close to $ I ,000 per sampling
event, and sampling can take between 3 and 5 days in the field, dependent on accessibility, field
conditions, and instrnmcnt performance. The cost of staging, sampling, and disposing of IDW is
eliminated with the use of PDBs. Any water that might be accumulated from the PDBs
following sampling is minimal and can be allowed to evaporate.
PDB samplers should replace low-flow sampling for the nine existing accessible wells in the
monitor well network. PDBs should be placed downhole to equilibrate for the next successive
