Davis Park Road TCE Site
Section: 1
Revision: O
Date: May 2005
Weston Solutions, Inc., (WESTON@) has been tasked hy the U.S. Envirnnlllclllal Prntcction
Agency (EPA) Region 4 10 pcrfor111 the Long Tenn Response Action (L TRA) al the Davis Park
Road Trichloroethenc (TCE) Site in Gastonia, North Carolina. The work is conducted under the
Region 5 Re111edial 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 co111pounds (YOCs) 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 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 cast 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 2005 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 1
Revision: O
Date: May 2005
The plume of contaminated groundwater underlies residential areas along the plume's entire
horizontal extent. The contaminant levels and aerial extent arc 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 1997 and early 1998, after petitioning the city for
water services, all of the homes in the Ce'dar 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 the carbon filtration units arc 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 2005 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 1
Revision: 0
Date: May 2005
According to preliminary site investigation reports (sec RI Report, I 998, 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 concen1ra1ions ofTCE (34.9 micrograms per lilcr lµg/11), lc\rachluroclhcne (PCE) (21.7
µg/1), and chloroform (9.2 µg/1). Analytical results for a confirma1ion sample collected from this
well on I 7 April 1990 were similar to the original sample. Groundwater samples collected from
three nearby private wells in May 1990 by the Gaston County Health Departmcnl indicated !hat
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 (sec
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 Contaminanl Level (MCL) for TCE and
PCE is 5 µg/1. Current State (North Carolina Department of Environment and Natural Resources
[NCDENR]) MC Ls for TCE and PCE arc 2.8 ~tg/1 and 0.7 µg/1 respectively.
The Environmental Services Division or 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 ftg/1 and 31 ftg/1 in groundwater sampled from
the private well located at 2419 Davis Park Road and a Cedar Oak Park subdivision well (2719
Davis Park Road), respectively.
Additional investigations and groundwater sampling events pnor to the initiation or 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 !low 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 iii an effort to further define the source area for the water supply
well conlaminants. environmental assessments were conductcdi including the Site Inspection
Addendum (SI) (May 1993), Expanded Site Investigation (ES!) (May 1994), and RI (1996-
1998). The RI report summari1/.es 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
vadosc zone and the saprolitc/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. Currently, the YOC 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 or Gastonia Restricted Use Water Linc; 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 monitoring wells were installed during completion or 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 monitoring 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 2001 RA to execute the provisions of the
ROD for the site. A sum1nary of analytical clata for the primary constituents of concern (PCE and
TCE) detected in groundwater sampled at the Davis Park Road TCE Site is presented in Table I-
I. 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 10 execute the provisions of the
ROD. This data is included for PCE and TCE in Table 1-1. As descrihed 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 cast and west of Davis Park Road.
1.4 SITE GEOLOGY AND HYDROGEOLOGY
The geologic profile across the site generally consists of a saprolitc layer, underlain by a partially
weathered rock zone and the underlying fractured crystalline bedrock. The saprolitc is a silty,
clay-rich, residual material derived from in-place weathering of rock. The saprolitc zone appears
to he 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.

LONG TERM RESPONSE ACTION
The ROD for the Davis Park Road TCE Site (Septemher 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 n:sults 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. Results from the quarterly sampling and first three rounds of
semiannual sampling are summarized below. Results from the fourth and most recent
semiannual 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 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 2005 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 2
Revision: O
Date: May 2005
The eighteen bedrock wells initially included for groundwater sampling in each LTRA
monitoring event included four bedrock monitoring 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 or Davis Park Road (MW-10 ;ind
MW-11), four converted wells (MW-12 through MW-15), and three private wells (MW-16
through MW-18). Monitoring wells MW-2, MW-5, MW-6, MW-9, MW-12. MW-15, MW-16.
MW-17, and MW-18 were selected lo provide groundwater qu;tlity inform;1tion within the
contaminant plume. The remaining monitoring 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 or potential contaminant migration.
Beginning with the first year fourth quarter sampling event, MW-13 was removed from the
sampling network and replaced with MW-I 9, 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 or the site (MW-IO and MW-11). 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 well 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 quarterly and semiannual groundwater monitoring is to verify the following:
• Thal 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,
• Verification that the plume is not expanding,·

I 2.2 FIRST YEAR OUARTERL Y LTRA SAMPLING EVENTS (2002/2003)
I 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 I 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 I monitoring. Thirteen of the 18 wells selected for the sampling network and two additional wells
were sampled in the baseline-sampling event. All I 8 wells in the LTRA sampling network were I sampled during the second and third quarter sampling events, performed in September and
December 2002, respectively.

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 aquif"cr in first through fourth quarter LTRA sampling events indicated a grnundwatcr
llow direction in the bedrock aquifer ranging from south to cast across the site, with the strongest
component of llow 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 llow direction trending to the southeast and Blackwood Creek. First through
fourth quarter analytical results arc detailed in the LTRA Second, Third, and Fourth Quarter
Sampling Event Reports submitted to EPA in January, April, and June 2003, respectively.

Following the first year of quarterly sampling at the Davis Park Road Site. two additional
monitoring wells were installed between the contaminant plume and the currently pumping
community wells MW-10 and MW-I I. These wells, designated MW-20 and MW-21, were
incorporated into the LTRA monitoring well network and sampled in August 2003. February
2004. and August 2004. During these sampling events, the nine wells in the monitor well
network that could he accessed at the well-head were sampled using both low-llow technology
and passive diffusive bag (PDBJ samplers. PDBs were evaluated and found to be an effective
sampling alternative to the low-llow method of sampling. PDBs were subsequently
recommended as the select method for sampling monitoring wells that can be accessed for the
remainder of the LTRA.
PDBs arc polymer membranes lilied 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 lluids.
The potentiometric map for the bedrock aquifer based on the semiannual L TRA sampling events
indicated a groundwater llow direction in the bedrock aquifer ranging from south to cast 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 llow. This llow component was attributed 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

I WESTON 111obilized lo the site the week of I February 2005. With the exception of one location,
MW-6, which could not be accessed, groundwater sa111ples were collected fro111 all wells in the I 111nni1or well network from I February through 2 February 2005. PDB sa111plers were used lo
sample the nine 111onitoring wells that can be directly accessed al the Davis Park Road Site (MW-
I I through MW-4, MW-12, MW-14, MW-15, MW-20, and MW-21). Hanger assemblies, to
which PDBs in protective 111esh were attached, were placed al selected depths along I polypropylene ropes for each of the accessible wells during the August 2004 sa111pling event (see
Table 3-1 ).

then equilibrate with the surrounding groundwater for the next sampling event (scheduled for
February 2006).
All samples were placed on ice prior to shipment under CLP protocol to EPA -A4 Scientific,
located in The Woodlands, Texas, for VOC analysis using EPA Method 8260.
3.1.2 Community and Private \Vcll Sampling Prorcdurcs
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 lo any
filter mechanism that may have been in place. Wells were purged al approximately I gallon per
minute for a period of approximately 15 minutes. Specific conductivity, pl-I, 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-
milliliter (ml) glass vials. Water quality data sheets and field log notes arc provided in
Appendix A.
3.1.3 Field Quality Assurance/Quality Control Samples
One rinse blank, one trip blank, two duplicates and one lab-grade deionized water sample were I 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 samples
were collected from well MW-15, using two PDB samplers, and well MW-9 (supplied with a

carbon filter unit). The lab-grade deionized water sample was collected by pouring lab-grade
deionized water directly from the water container into the sample vial. All samples were
analyzed for VOCs using EPA Method 8260.
Analytical results for the QA/QC sa111ples arc su111111arized in Table 3-2. Chloroform was I detected in the rinse blank, trip blank, and laboratory-grade deionized water sa111plc at estimated
concentrations below the reporting li111it. No other VOCs were reported in the QA/QC sa111ples.
Chlorofor111 was detected in groundwater samples collected fro111 MW-7 and MW-17 at
estimated values below the reporting limits. Chloroform was not cktected in groundwater
samples collected from PDBs.

Duplicate results were comparable to previous sa111pling events ($25'fo relative percent
difference) for all COCs identified at concentrations above the reporting limit.
3.2 GROUNDWATER ELEVATION
WESTON collected water level measurements relcrenced to the top of the well casmg for I monitoring wells MW-I through MW-4, MW-12, MW-14, MW-15, MW-20 and MW-21 on I
and 2 February 2005 (Table 3-3). Depth to water was measured using an electronic water level I meter. The water level probe and tape were deconta111inated prior to each 111easurement. Figure 3-
1 provides a potentiometric surface map of the bedrock aquifer. During the previous se111iannual I sampling event, data from monitoring well MW-21 was considered ano111alously high, and not
included for development of the potentiometric surface map. During this sa111pling event, the I water level in this well was carefully evaluated and measured at various times during the event to
confir111 findings and to evaluate for potential fluctuations. The water level remained I anomalously high relative to the other 111onitoring wells in the well network. It is likely the well

I
I
TCE and PCE were the only VOC constituents to exceed the ROD Performance Standards in
groundwater samples collected during the February 2005 Semiannual LTRA sampling event.
TCE and/or PCE were detected in groundwater sampled from 8 of the I 9 wells sampled. The
Performance Standard of 2.8 µg/1 (TCE) and/or I µg/1 (PCE) was exceeded in 6 groundwater I samples. TCE exceeded the ROD Performance Standard in the following samples: MW-9 (9.4
µg/1), MW-15 (39 µg/1), and MW-17 (12 µg/1). PCE exceeded the ROD Performance Standard in I the following samples: MW-2 (2.0 µg/1), MW-12 (1.2 ftg/1), MW-17 (5.3 µg/1), and MW-18 (3.9
µg/1). Monitor well MW-6 which has historically exceeded the ROD Performance Standards for I TCE and PCE could not be accessed for sampling during this event.

The highest TCE concentration (39 µg/1) was detected in groundwater sampled from monitor
well MW-I 5, located at the west central portion of the site. The second highest TCE
concentration ( 12 µg/1) was detected in groundwater sampled from monitor well MW-I 7, located
on the southern side of the site. The highest PCE concentration (5.3 µg/1) was also detected in
groundwater sampled from MW-17. The second highest PCE concentration (3.9 µg/1) was

February 2005 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 3
Revision: O
Date: May 2005
detected in groundwater sampled from MW-I 8, located near the south southeastern corner or the
site.
TCE and PCE concentrations decreased slightly in all or the wells sampled in the Fchruary 2005
sampling event when compared to the August 2004 groundwater sampling results. PCE and TCE
concentrations in groundwater have generally remained stable or decreased at sampling locations
during the first three years 01· the Davis Park Road TCE Site LTRA. There arc two areas where
PCE and TCE concentrations continue to exceed guidance concentrations. One area is
downgradient or 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 or the site. PCE
and TCE concentrations in both these locations remain lower than historical detections in the
former plume center.
Trace concentrations of PCE that were previously detected in groundwater sampled from
locations west and north or the former plume boundaries were not confirmed during the August
2004 or current (February 2005) sampling event. Pumping from community wells in this area
docs not appear to be causing significant migration of the contaminant plume in this direction.
MTBE was detected in the following samples: MW-3 (11 µg/1), MW-7 (0.231 µg/1), MW-8
(0.421 µg/1), MW-9 (0.151 µg/1), MW-I I (0.161 µg/1), MW-15 (0.091 µg/1), MW-17 (0.88 µg/1)
and MW-20 (70 µg/1). MTBE concentrations have generally remained stahle or decreased
during the first three years of LTRA. The ROD Performance Standard or 200 ftg/1 for MTBE
has not historically been exceeded and five of the seven detections during the current sampling
event are estimated values below the reporting limit.

SECTION 4
February 2005 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: O
Date: May 2005
CONCLUSIONS AND RECOMMENDATIONS
4.1 LTRA RESULTS SUMMARY
The source for the TCE/PCE cont"rnin"tion in groundwater at the Davis Park Road TCE Site is
depleted or rernoved based on groundwater sampling results reported from the tirne of
contaminant discovery ( 1990) to the current February 2005 LTRA semiannual sampling event.
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 ~tg/1 TCE and up to 24
µg/1 PCE when sampled in 1990. Water sampled from MW-5 and MW-14 in February 2005 did
not contain concentrations of TCE or PCE above the reporting limit. Water sampled fro1i1 MW-
12 contained TCE at 2.2 µg/1 and PCE at 1.2 µg/1. Figures 4-1 through 4-3 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-I 5, located southwest of the source area, contained 39 µg/1 TCE during the
current sampling event. Excluding this groundwater sample, the maximum TCE concentration
for groundwater samples collected this sampling event is 12 µg/1 in groundwater sampled from
well MW-I 7. The maximum PCE ·concentration is 5.3 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 2005 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: O
Date: May 2005
Concurrently with the migration toward Blackwood Creek, the August 2003 and February 2004
sampling data indicated a contaminant migration southwest or the source area, as evidenced by
groundwater elevations and the detection of trace TCE and PCE concentrations in groundwater
sampled from the western side or the site. However, the August 2004 and February 2005
sampling results show no detections of TCE or PCE on the west side or the site. Although
pumping or groundwater has been discontinued over most of the Davis Park Road TCE Site area,
two community wells (MW-10 and MW-I I) arc currcmly "ill active near Briar Oak Drive. west
of the site. Community well MW-10, 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. Monitoring 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 arc located
. between MW-15 (the well with the highest TCE concentration) and the currently pumping
community wells. The data from sampling wells MW-20 and MW-21 do not currently indicate
that COCs in groundwater are migrating toward the pumping wells.
Monitor well MW-15 is located southwest or 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
lluctuated between 36 µg/1 and 50 µg/1 since September 2002 (sec Figure 4-4), similar to
historical levels detected in groundwater sampled from converted community well MW-12
(located cast and downgradient or the source area) (sec Figure 4-3). TCE concentrations
lluctuated between approximately 30 and 50 µg/1 in groundwater sampled from MW-12 from
1990 through 1998. TCE was detected at 2.2 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 lluctuatcd since August 2000 when first

February 2005 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: 0
Date: May 2005
sampled, but have ranged from 6.8 µg/1 (detected in November 2001) to 16 µg/1 (detected in
March 2003). These levels arc 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.
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 monitoring wells arc presented as Figures 4-1 through 4-6. 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
4-6 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 arc consistent with the
proposed cleanup time of 13 years (by the year 2017) to attain EPA MC Ls.
In conclusion, the February. 2005 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
arc being produced, the plume is not expanding, there is no impact downgradicnt, there 1s no
evidence of a new release, and source area wells have attained remediation objectives.

4.3 RECOMMENDATIONS
February 2005 Semiannual Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: 0
Date: May 2005
Analytical results from quarterly and semiannual sampling of the monitor well network at the
Davis Park Road Site indicate decreasing levels of COCs. Perimeter wells located outside !he
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
Sile. while al !he same lime being more easily i111plc1ncnled and cos1-cllec1ivc than low-flow
sampling methods. It is recommended that PDBs continue 10 be used to sample accessible wells,
and that sampling frequency be reduced to annually for the duration of the LTRA. Additionally,
!he owner of monitor well MW-14, localed north and upgradienl of !he current contaminant
plume, requested permission lo abandon the monitor well on her property al 2404 Davis Park
Road. Because samples from this well have not contained COCs at levels exceeding the
reporting limit since LTRA sampling began in September 2002, it was agreed this well is no
longer necessary to the monitor well network. It is recommended that MW-14 be removed from
the LTRA monitoring program and that MW-14 be abandoned.
It is also recommended that well condition be recorded during each sampling event using the
format provided in Table 4-1. During the current sampling event, several monitor wells in the
L TRA network were observed to be in need of minor repairs (sec Table 4-1 ). Additionally, in
order to minimize the chance that access to any given well in the monitor well network is denied
during future annual site visits, it is recommended that a letter be sent by EPA to the property
owners a week or two in advance, informing them of the expected sampling date, and in order to
ensure location of all remaining monitor wells during future sampling events it is recommended
that they be located with a Global Positioning System (GPS) unit.
