INTRODUCTION
Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 1
Revision: 0
Date: June 2003
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 138-RALR-04PN. The
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 three 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 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.

Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 1
Revision: O
Date: June 2003
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. 1n 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 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, 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.

1.3.1 Contaminant Source Area
Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 1
Revision: O
Date: June 2003
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 I sampling procedure in accordance with "Community Well Rules." Analysis of the sample
revealed concentrations of TCE (34.9 micrograms per liter [µg/Ll), tetrachloroethene (PCE)

(23.7 µg/L), and chloroform (9.2 µg/L). A confirmation sample was collected from this well on
I 7 April 1990, and analytical results 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/L) 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/L. Current State (NCDEHNR) MCLs for TCE and PCE are 2.8 µg/L and 0.7 µg/L
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/L and 31 µg/L in groundwater sampled from
the private well located at 2419 Davis Park Road and a Cedar Oak Park subdivision well,
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 sm1rce
at the Davis Park Road TCE Site (NCDEHNR Site Inspection, 1993).
As a result of these findings and in an effort to further define the source area for the water supply I well contaminants, environmental assessments were conducted, including the Site Inspection
Addendum (SI) (May 1993), Expanded Site Investigation (ES!) (May I 994), and RI ( I 996-
I
I
I
I
I
I
I
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. Currently, 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 imd I 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 I 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-
I
I
I
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 I 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 I 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

I
I
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. l11is 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.
I 1.4 SITE GEOLOGY AND HYDROGEOLOGY
I
I
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, I thinning towards the lower elevations or stream valleys to approximately 20 feet in thickness. A
I
I

I
D
partially weathered rock layer typically underlies the saprolite, and ranges in thickness form
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 .

Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 2
Revision: O
Date: June 2003
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. 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 Attenua.tion Plan (submitted to EPA in
October 2002) was developed to include sampling a network of 18 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.
The 18 bedrock wells to be included for groundwater sampling in each L TRA monitoring event
include 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-JO and MW-I I), 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 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, provide evidence of potential contaminant migration. 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 GROUNDWATER MONITORING
The purpose of quarterly 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,
• The 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, and
• 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.
All samples are analyzed by laboratories m the Contract Laboratory Program. Samples are
analyzed for voes.
2.2 FIRST, SECOND, AND THIRD QUARTER LTRA SAMPLING EVENTS
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 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.
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 third 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 third quarter
LTRA 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, second,
and third quarter analytical results are detailed in the LTRA Second Quarter Sampling Event
Report and the L TRA Third Quarter Sampling Event Report, submitted to EPA in January and
April 2003, respectively.

FOURTH QUARTER LTRA SUMMARY
3.1 GROUNDWATER SAMPLING
3.1.1 Monitor Well Sampling
WESTON mobilized to the site the week of 10 March 2003. Groundwater samples were
collected from 12 March through 13 March 2003. Samples were collected from 17 of the 18
monitor wells in the current monitor well network. Monitor well MW-13 could not be accessed
due to hostile property owners. Groundwater was sampled instead from the residence at 2833
Davis Park Road (see Figure 1-4), MW-19.
Monitor wells MW-I through MW-4, MW-12, MW-14, and MW-15 were sampled 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) were
recorded on field data sheets which are included in Appendix A. Pump intake was lowered to
well screen depth, and the well was micro-purged until field parameters stabilized. Laboratory
samples for VOC 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, Clayton Environmental
Consultants located in Novi, Michigan.

All downhole equipment was decontaminated after use in each well. Purge water was collected
and transported to stationary containment located on the property behind the Davis Park Auto
facility pending sample analysis for determination of method of disposal.
3.1.2 Community and Private Well Sampling
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 while sampling monitor
wells MW-6, MW-7, MW-8, MW-11, MW-I 4, and MW-I 5 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. Field parameters were not recorded for
monitor wells MW-5, MW-9, MW-10, MW-16, MW-17, and MW-18 due to malfunctioning
· equipment. Purging continued for approximately 15 minutes prior to sampling of these wells.
Historically, field measurements have stabilized prior to terminating the 15-minute purge. Field
parameter data sheets are included in Appendix A.
3.1.3 Field Quality Assurance/Quality Control Samples
One rinse blank, one trip blank, and one field blank were collected during the sampling event.
The rinse blank was collected by pouring distilled water over the submersible pump. The trip
blank was collected by pouring distilled water directly from the distilled water container into the
sample vial. This blank was stored with collected samples throughout the sampling event. The
field blank was collected proximal to MW-3 by pouring distilled water directly from the
container into the sample container. One field duplicate was collected from MW-I 8.
Additionally, one composite sample (MW I PW) was collected from the purge water. All
samples were analyzed for VOCs using EPA Method 8260.

Analytical results for the QNQC samples are summarized in Table 3-1. Toluene was detected in
the rinse blank, trip blank, field blank, and purge water sample. Detections of these constituents
were of estimated concentrations (below the laboratory detection limit). Toluene was not
detected in any groundwater sample. Duplicate results were within acceptable relative percent
differences.
3.2 GROUNDWATER ELEVATION
Depth to water was recorded for monitor wells MW-I through MW-4, MW-12, MW-14 and
MW-15 prior to sampling. Field measurements from the first through fourth quarter sampling
events arc summarized in Table 3-2. Field data sheets are included in Appendix A. Figure 3-1
provides a potentiometric surface map of the bedrock aquifer. Consistent with the first quarter
LTRA event and previously reported data, groundwater flow direction in the bedrock aquifer
appears to range from south to east across the site, with the strongest component of flow to the
southeast.
3.3 GROUNDWATER ANALYTICAL RESULTS
3.3.1 Groundwater Samples
TCE and PCE were the only VOC constituents to exceed the ROD Performance Standards in
groundwater samples collected during the Fourth Quarter LTRA sampling event. TCE and/or
PCE were detected in groundwater sampled from 14 wells. However, the Performance Standard
of 2.8 µg/L (TCE) and/or I µg/L (PCE) was exceeded in only six groundwater samples. TCE
exceeded the ROD Performance Standard in the following samples: MW-2 (4.1 µg/L), MW-6
(3.4 µg/L), MW-9 (16 µg/L), MW-15 (40 µg/L), MW-17 (14 µg/L), and MW-18 (4.4 µg/L).
PCE exceeded the ROD Performance Standard in the following samples: MW-2 (3.0 µg/L),
MW-6 (3.0 µg/L), MW-17 (6.2 µg/L), and MW-18 (9.1 µg/L). Laboratory analytical results for

Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 3
Revision: o
Date: June 2003
first through fourth quarter LTRA sampling events are summarized in Table 3-3. 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 (40 µg/L) was detected in groundwater sampled from monitor
well MW-I 5, located at the west central portion of the site. TCE concentrations in groundwater
sampled from this well increased from 36 µg/L detected during the third quarter sampling event,
but decreased from 50 µg/L detected during the second quarter sampling event. This well was
not sampled during the first quarter sampling event. The second highest TCE concentration (16
µg/L) was detected in groundwater collected from monitor well MW-9, located on the western
side of the site. TCE concentrations in groundwater sampled from MW-9 have increased from 14
µg/L, detected during the first quarter sampling event. The highest PCE concentration (9.1 µg/L)
was detected in groundwater sampled from MW-I 8, located near the southeast corner of the site.
This concentration has increased from 8.6 µg/L detected during the first quarter sampling event.
PCE and TCE concentrations in groundwater generally remained stable or decreased at the north
central and eastern portions of the site during the first through fourth quarter sampling events at
the Davis Park Road TCE Site. However slight increases in PCE and TCE concentrations were
observed at the south and southeastern portions of the site. There appear to be two areas where
PCE and TCE concentrations continue to exceed guidance concentrations. One area is
downgradient of the 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. Additionally, trace concentrations of TCE
and/or PCE have now been detected and confirmed in groundwater sampled from locations west
and north of the former plume boundaries, where formerly these constituents were not detected
(e.g., MW-3, MW-8, MW-10, MW-I I). Trace concentrations of TCE and PCE were also
detected in private well MW-19 located at the south-southwestern portion of the site. This well
was sampled during the fourth quarter sampling event but had not previously been included as
part of the monitor well network.

3.3.2 Purge Water Sample
Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 3
Revision: o
Date: June 2003
Purge water was contained in a 55-gallon drum secured in the area of MW-3 and MW-8, on the
property behind the Davis Park Auto facility. Following sampling activities the drum was
sampled for VOC analysis to determine proper disposal. The analytical results for the purge
water sample are summarized in Table 3-I. The purge water contained concentrations of PCE
(0.12 µg/L), TCE (0.59 µg/L), methyl I-butyl ether (I.I µg/L), chloroform (0.16 µg/L),
tetrachloroethene (0.12 µg/L) and toluene (0.12 µg/L) below guidance concentrations. The drum
contents, profiled as non-hazardous, will be transported and disposed appropriately.

Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: O
Date: June 2003
(;ONCLUSIONS 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 LTRA fourth quarter sampling event in March 2003.
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/L TCE and up to 24
µg/L PCE when sampled in 1990. Water sampled from these same wells in March 2003 did not
contain concentrations of TCE or PCE at concentrations greater than the ROD remedial
groundwater clean-up goals of 2.8 µg/L and I µg/L, respectively (see figures 4-1 through 4-3).
Although TCE and PCE concentrations in some wells located south and west of the source area
have 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 40 µg/L TCE during
the current sampling event. Excluding this groundwater sample, the maximum TCE
concentrations for groundwater samples collected during the fourth quarter L TRA sampling
event are I 6 µg/L in groundwater sampled from well MW-9 and 14 µg/L in groundwater
sampled from MW-17. The maximum PCE concentration is 9.1 µg/L in groundwater sampled
from well MW-I 8. Both wells MW-17 and MW-18 are 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.

Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: O
Date: June 2003
Concurrently with the migration toward Blackwood Creek, there appears to be contaminant
migration southwest of the source area. Although pumping of groundwater has been
discontinued over most of the Davis Park Road TCE site area, two community wells (MW-I 0
and MW-I I) are currently still 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 1, 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. 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 are similar to historical levels originally
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 concentrations fluctuated
between approximately 30 and 50 µg/L in groundwater sampled from MW-12 from 1990
through 1998. TCE was detected at 2.4 µg/L 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 fluctuated since August 2000 when first
sampled, but have ranged from 6.8 µg/L (detected in November 2001) to 16 µg/L (detected in
March 2003). These levels are similar to groundwater samples collected from well MW-18,
located further south and downgradient of the source area toward Blackwood Creek (see Figures
4-5 and 4-6).
4.2 CONCLUSIONS
TCE and PCE concentrations continue to decrease in the contaminant plume as it migrates south
and away from the source area. Additionally, 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 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

Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: O
Date: June 2003
through 4-3 shows the decline of Constituents of Concern (COCs) in groundwater sampled near
the original plume center from levels well above EPA MCLs to levels consistently below the
MCLs and ROD Performance Standards from 1990 through the current sampling event.
Figures 4-4 through 4-6 illustrate the fluctuating COC levels in wells located at 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 14 years (by the year 2017) to attain EPA MCLs.
In conclusion, the Fourth Quarter LTRA sampling event results confirm that natural attenuation
is occurring at rates according to expectations, no toxic and/or mobile transformation products
are being produced, there is no evidence of a new release, and source area wells have attained
remediation objectives. However, trace levels of TCE and PCE have been confirmed in two
wells that are currently pumping as supply wells for one community well system (15 or more
subscribers) and one private well system (2 to 14 subscribers) located southwest of the source
area. The confirmed concentrations suggest contaminant migration southwest of the source area
in addition to the previously documented southeast migration toward Blackwood Creek, the
natural groundwater discharge area southeast of the site.
4.3 RECOMMENDATIONS
The data obtained from the first year L TRA were reviewed and analyzed with respect to the
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.
Recommendations for the second year LTRA include:

Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: O
Date: June 2003
• Reducing the sampling program from quarterly to semiannually
• Removing well MW-13 from the monitoring network
• Adding well MW-19 to the monitoring network
• Installing two additional bedrock monitor wells and including these wells in the
monitoring network
• Replacing low-flow groundwater sampling procedures with passive diffusion bag (PDB)
samplers
4.3.1 Sampling Frequency
The first year LTRA for the Davis Park Road TCE site included monitoring the bedrock aquifer
contaminant plume by sampling a network of I 8 bedrock wells for volatile organic compounds
(VOCs) on a quarterly basis. First year LTRA sampling results confirmed that TCE and PCE
concentrations continue to decrease in the contaminant plume as it migrates south and away from
the source area. Contaminant concentrations did not show a high degree of variability among the
wells sampled during the first year. The greatest fluctuation in TCE concentration for a given
well during the year's sampling was 14 µg/1 (MW-15). The average fluctuation in TCE
concentration for a given well over the year was 1.9 µg/1. Because the plume continues to
naturally attenuate at rates according to expectations and analytical results appear to be relatively
stable from quarter to quarter, it is recommended that sampling be reduced to a semi-annual basis
for the next two years, and annually thereafter for 27 years, pending review of analytical results,
to ensure the plume is naturally attenuating.
4.3.2 Monitor Well Network Modifications
Of the 18 bedrock wells included for groundwater sampling in each LTRA monitoring event,
wells MW-2, MW-6, MW-9, MW-15, MW-16, MW-17, and MW-18 continue to provide
groundwater quality information within the contaminant plume. Wells MW-5 and MW-12

formerly monitored groundwater quality information within the contaminant plume, but have not
contained TCE or PCE concentrations above ROD levels for two consecutive sampling events.
Wells MW-5 and MW-12 and the remaining wells (MW-I, MW-3, MW-4, MW-7, MW-8, MW-
10, MW-11, and MW-14) are currently located outside the contaminant plume, and provide
evidence of potential contaminant migration. Well MW-13 has historically never contained TCE
or PCE at detectable levels, and is not a currently active (i.e., pumping) well. Because
groundwater sampled from this well during the first, second, and third quarter sampling events of
the first year LTRA did not contain detectable concentrations of TCE or PCE (consistent with
historical data), and because groundwater sampled from MW-12 will provide information
concerning changing conditions, should this become an issue in this area of the site, it is
recommended that MW-13 be dropped from the LTRA monitor well network.
Well MW-19, sampled during the fourth quarter LTRA sampling event, contained trace
concentrations of TCE and PCE. Because this residential (pumping) well is also located
downgradient of wells that have contained TCE and PCE above ROD levels, it is recommended
that MW-19 be added to the L TRA monitor well network to provide further° evidence of potential
contaminant migration south of the groundwater contaminant plume.
4.3.3 Monitor Well Installation
To more effectively monitor the western component of groundwater contaminant migration, it is
recommended that two bedrock wells be installed west of Davis Park Road, and east of the two
currently active well systems (MW-10 and MW-11). Proposed locations are shown in Figure 4-7
(wells are identified as MW-20 and MW-21). The new wells will provide information
concerning groundwater flow as well as providing evidence of potential contaminant migration.
An inactive (non-pumping) residential well was identified at the location of proposed well MW-
21. Reportedly a pump was dropped down the well and was not recoverable. The residence is

Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: 0
Date: June 2003
currently connected to the Briar Oak Drive water supply private well system. If feasible, it is
recommended that this well be converted to a monitor well using the following procedures:
• The existing pump and existing protective cover will be removed and disposed.
• The well will be developed until the discharge is relatively clear and sediment free.
Development water will be contained on site pending proper disposal.
• The well will be completed at surface with a flush-mount, consisting of an 18-inch wide
by IO-inch deep watertight manhole set within a 3-foot square and 6-inch deep concrete
pad. Concrete will be composed of Portland type 1-11 cement and sand aggregate mixed
with potable water. The concrete pads will be sloped to allow runoff. The pads will
extend two feet down into the borehole and will be bonded to the grout.
If the existing well is not appropriate or cannot be accessed, it is recommended that a well be
installed at this location. Wells MW-20 and MW-21 would be installed using air rotary
techniques. The drill rig and drilling materials should be decontaminated prior to beginning
fieldwork and between installations of each well. The materials and methods used in the
construction of the monitoring wells would include the following:
• The regolith/overburden and first five feet of competent, unweathered bedrock will be
drilled using air rotary techniques with a nominal IO-inch tri-cone roller bit.
• A 6-inch inner diameter, carbon steel surface outer casing will then be set and grouted
into place. The outer casing will be placed in the borehole and pushed firmly to the
bottom of the borehole and into the bedrock. The well casing will be installed with a
guide shoe with float collar. The well casing/grout string assembly will be raised enough
to allow pumping of grout, and the annular space will then be pressure-grouted with a
cement/bentonite grout until all mud is flushed from the annulus and grout is observed at
ground surface. The casing will be seated in the bottom of the recess in the bedrock
surface, and the grout allowed to cure for at least 24 hours. All cuttings will be placed
temporarily into 55-gallon drums and removed to a storage area prior to completion of
activities at each well location, pending proper disposal.
• After the grout has set, drilling will continue using a 5 and 3/4-inch outer diameter (O.D.)
air hammer bit.

Date: June 2003
• The wells will be completed when the first significant fracture zone is detected or
significant secondary permeability features (fractures, open schistose/gneissoid textures)
are detected. The wells will be completed as open corehole wells.
• Completion at surface will be flush-mount, consisting of an 18-inch wide by IO-inch deep
watertight manhole set within a 3-foot square and 6-inch deep concrete pad. Concrete
will be composed of Portland type 1-11 cement and sand aggregate mixed with potable
water. The concrete pads will be sloped to allow runoff. The pads will extend two feet
down into the borehole and will be bonded to the grout.
• The wells will be developed no sooner than 24 hours from the time the grout seal is
placed. Wells will be developed using pumping techniques in accordance with US EPA's
SOP-QAM. A 4-inch submersible pump will be used to pump from each of the newly
installed wells. Pumping will continue for a minimum of one hour until sediment
production is negligible. The well will then be pumped continuously while purge rate,
depth to water, pH, temperature, conductivity, and turbidity are recorded every 15
minutes. Well development will continue until turbidity measurements are 45
ncphelometric turbidity units (NTU) and readings are stable over three successive 5-
minute intervals, or for a maximum of one hour.
• Development water will be contained in a trailer-mounted temporary holding tank and
transported to a staging area, pending proper disposal.
Following well installation (or convers10n, if feasible), it 1s recommended that the well
elevations be surveyed by a North Carolina registered land surveyor. Tops of casings and
ground surface elevations of the new monitor wells MW-20 and MW-21 should be surveyed
relative to the National Geodetic Vertical Datum. Additionally, MW-15, which has not
previously been surveyed, should be surveyed at this time.
It is also recommended that downhole geophysical logging be conducted for wells MW-I 4, MW-
15, MW-20, and MW-21 to evaluate the construction and water bearing capacity of each
borehole, and to identify fracture zones and fractures that may be potential contaminant
migration pathways.

4.3.4 Passive Diffusion Bag Samplers
Fourth Quarter Sampling Event Report
Davis Park Road TCE Site
Section: 4
Revision: O
Date: June 2003
It is recommended that PDB samplers replace low-flow groundwater sampling procedures for
semi-annual L TRA sampling events to maximize sampling efficiency and to eliminate the need
to contain, sample, and dispose of purge water. Prior to the well installation effort, PDB
samplers will be placed at select depths (see Table 4-1) in monitor wells in the current LTRA
monitor network that can be accessed (MW-I through MW-4, MW-12, MW-14, and MW-15).
Following MW-20 and MW-21 well installation, the PDB samplers will be pulled and
groundwater sampled for VOC analysis. Each monitor well will also be sampled using low flow
sampling procedures after the PDB sample is pulled. Following validation of sampling results,
passive diffusion bag sampling will replace the low flow sampling technique for the remaining
part of the L TRA. The two recommended additional wells will also be sampled using PDB
samplers following the initial sampling using low flow groundwater sampling procedures.
