SUPERFUNO SECTION
I hope this summer finds you well. As you may know I am the EPA project manager for
the Davis Park Road TCE Site, where EPA's contractors are installing water lines as well some
carbon filters at those homes which are or may become impacted by the groundwater ·
contamination in the area.
Earlier this year EPA offered to provide you with either a connection to the water line or a
carbon filter and one year of maintenance. This was based on the location of your home over the
area of actual or potential groundwater contamination. You elected to receive the carbon filter.
It has since come to our attention that the well from which you receive y01.J'drinking water
is the community well located on Briar Oak Drive. This well is not in the area of concern for
Site-related contamination, and is considered to be "safe." EPA should not have offered you the
filter installation option, since there is no Site-related contamination to "filter" from your water
supply. Therefore EPA is not planning at this time to install a filter at your home.
I apologize for this misunderstanding. Please feel free to call me if you would like to
discuss this further, or if you would like to reconsider the opportunity to connect to City water
services. Also, please contact me if for some reason I am still not correctly understanding the
location of the source of your well water.
I can be reached at 1-800-435-9233.

•
I apologize for the delay in getting back with you, but I have since talked with
the Contractor (Troy Reeves) and the City's (Building) Inspection Department. (I
am awaiting a call back from Doug Mauney of Weston.) However, the following
information is my understanding of the concerns to date and is herein provided.
Trans State (through their sub-contractor) has applied for 67 plumbing permits
for the subject project. · There are six (6) additional ones (properties) without
permits that we're checking on; these may have been properties that went with
a filtering system in lieu of a water hook-up. The 67 permits are ready to be
picked up. Unfortunately, the contractor will also have to pay for these; City
staff cannot waive said fees. ·
In addition, in. order to verify that the (service) lines have been installed to State
(plumbing) Code, each connection point (at both ends) will need to be uncovered
and inspected. To do otherwise could shift a potential liability to the City for
accepting non-inspected work.
It is my understanding that the NC Plumbing Code also requires a "cut-off'
between the meter (box) assembly and the pressure reduction valve (PRV).
Deleting such could again could place liability on the City for allowing non-
conforming work.
I regret that I couldn't provide more favorably information, but I also believe
that it's in everyone's best interest (both EPA, Weston, and the City) to complete
the work in accordance with the State Plumbing Code. This minimizes potential
(future) liability to all three parties concerned.
Please call if you need further information. As always, we appreciate the efforts
of the EPA to jointly solve a community's water system concern(s).

SUPERFUND PRELTh1INARY CLOSE-OUT REPORT
DA VIS PARK ROAD TCE SITE
GASTONIA, NORTH CAROLINA
NCD986175644
I. INTRODUCTION
1This Preliminary Close Out Report documents that the U.S. Environmental Protection
Agency (EPA) completed construction activities at the Davis Park Road TCE Site (Site) in
accordance with Close Out Procedures for National Priorities List Sites (OSWER Directive
9320.2-09A-P). EPA and the North Carolina Department of Environment and Natural Resources
(State) conducted a pre-final inspection on September 13, 2000, and determined that the
contractors have constructed the remedy in accordance with remedial design (RD) plans and
specifications, and no further response is anticipated. EPA and the State have initiated the
activities necessary to achieve performance standards and Site completion.
Il. SUMMARY OF SITE CONDITIONS
Background
The Davis Park Road TCE Site includes approximately 20 acres of residential homes and
private businesses in unincorporated Gaston County, southwest of the City of Gastonia. T_he Site
consists of a contaminated soil area that was reporteQly behind an automobile transmission shop
located at 2307 Davis Park Road, and a plume of contaminated groundwater that emanates from
this property and extends south along Davis Park Road to Blackwood Creek. The plume of
contaminated groundwater underlies residences at the Site along the plume's entire horizontal
extent. A majority of homes within the Site area obtain their water from private or community
wells. Tetrachloroethene (PCE), Trichloroethene (TCE), 1, 1-Dichloroethene (I, 1, -DCE),
Chloroform, and Methyl-ter-butyl ether (MTBE) are the groundwater contaminants of concern
identified in the ROD.
EPA proposed the Site to the National Priorities List (NPL) on July 28, 1998, and added
it to the final list on January 19, 1999.
Remedial Construction Activities
After the Remedial Investigation and Feasibility Study (RI/FS) were completed, on
September 29,' 1998, the Director, Waste Management Division, Region 4, signed the Record of
Decision (ROD) for this Site. The major components of the selected remedy are:
• Reduction of exposure to contaminated groundwater by connection of homes, churches,
and businesses in the Davis Park Road Site area to the City of Gastonia public water
supply;
• . ·.: · .... _ •
2
• Optional wellhead treatment for affected private wells;
• Natural attenuation to restore the contaminated aquifer to the lower of either the
Maximum Contaminant Levels (MCLs) or North Carolina Part 2L Drinking Water
Requirements. The primary attenuation processes occurring at the Davis Park Road TCE
S_ite are dispersion and intrinsic biodegradation;
)
• Continued analytical monitoring for contaminants in groundwater; and
• Collection of additional information during the first year of the Remedial Design effort in
order to support the predicted dispersion and intrinsic biodegradation rates for the
contaminated groundwater. · · ·
The ROD also contained a contingency remedy which would be implemented if the data
collected during the natural attenuation study did not substantiate that natural attenuation would
achieve remedial goals. The contingency remedy specified groundwater pumping, using a
minimum of three extraction wells, with treatment of contaminated groundwater using activated
carbon.
The RI/FS concluded that soil contamination at the probable source area for the
groundwater plume was no longer at levels warranting further ·action. It was also concluded that
migration of the groundwater plume toward Blackwood Creek would not result in a measurable
release of Site-related contaminants to the creek. ·'
Remedial goals for groundwater were selected as the most conservative of the chemical-.
specific ARARs or the health-based risk goals and are:
CONT AMIN ANTS OF MAXIMUM VALUES REMEDIAL GOALS
CONCERN MEASURED (ug/1) (ug/1)
Tetrachloroethene (PCE) 14 I

On July 23, 1999, EPA processed a work assignment under one of our available Remedial
Action Contracts (RAC) for the RD. As part of the RD a final list of homes to be connected to
the public water supply system or to receive carbon filters was determined. The remedial design
of the water lines and carbon filters was determined to be substantially complete in December
1999.
After obtaining funding, on February 16, 2000, EPA processed a work assignment under
the same Remedial Action Contract to begin the Remedial Action (RA). Actual on-site
construction of the water lines began on May 15, 2000.
RA construction included approximately 5625 linear feet of 12-inch, 8-inch and 6-inch
ductile iron pipe, plus related service lines and appurtenances. Roads, rights-of-way, and private
properties were returned to undisturbed conditions. A total of sixty three (63) residences were
connected to the City of Gastonia water system and are now receiving water from that system.
EPA installed carbon filters at five ( 5) residences where the homeowners would not agree to be
connected to the public water supply system. Two homeowners with private wells in the Site area
elected not to be connected to the public water supply system or receive a filter system ( one of
whom had initially agreed to receive public water). Water servict; is available to these two homes
via the EPA constructed water lines should the homeowners change their minds in the future,
however the physical connection would be their responsibility. Other changes from the RD
included the addition of one home not previously identified as impacted by the Site, the deletion
of one home already connected to City water, and the deletion of two homes connected to a
· community well not impacted by the Site.
EPA also physically abandoned 19 private wells by plugging with a cement grout. EPA
physically abandoned only those wells where the homeowners agreed to have them plugged. With
the conditional concurrence of local Public Health Department, other wells were disconnected
from the homes but left operational for watering gardens, etc.
A sampling effort for the natural attenuation study was conducted in November 1999. A
thorough review of the data, review of all historical data, and predictive analyses were conducted
and summarized in an EPA Region 4 Memorandum Report dated September 25, 2000. The
report focuses on TCE and PCE as the critical contaminants of concern.
TCE concentrations are projected to diminish to less than the 5 ug/1 Safe Drinking Water
Act Maximum Contaminant Level (MCL) in 12 years for the worst (slowest) estimate. Data from
most wells suggest that TCE concentrations in most wells will be less that the MCL in about 5
years. Remedial goals for this Site are based on North Carolina's groundwater standard for TCE,
which at 2. 8 ug/1 is lower than the MCL. A worst case estimate is that it will take 26 years to
achieve concentrations below that level in all parts of the plume. However, since the average
groundwater travel time to Blackwood Creek is estimated at 13 years, this estimate is probably
overly conservative.
• •
4
PCE concentrations are expected to diminish to less than the MCL (5 ug/1) in 15 years
assuming extreme worst case conditions. The remedial goal for PCE for this Site, 1.0 ug/1, is
based on North Carolina's groundwater standard and the minimum detection level. A worst case
estimate is that it will take 43 years to achieve concentrations below that level in all parts of the
plume. Since the estimated contaminant migration rate from the area of highest PCE
contamination to Blackwood Creek is approximately 7 -10 years, this indicates that our worst
case estimates for PCE may also be overly conservative.
The estimated time frames for natural attenuation are longer than, but basically consistent
with the ROD assumption and eliminates the need for the contingency remedy. EPA currently
plans to monitor groundwater from identified private wells and monitoring wells quarterly for the
next two to three years, for wells with limited historical data, and then annually thereafter for all
wells, until remedial goals are demonstrated to be achieved. Monitoring frequency will be
reevaluated as needed. '
The City of Gastonia has agreed in writing to assume responsibility for operation and
maintenance of the water lines, up to the water meter, after EPA completes the remedial action
construction. The homeowners will become responsible for maintenance of their service lines and
pressure reducing valves. EPA has agreed to maintain the five filter systems for a minimum of
one year from installation, including periodic testing of the pre-and post-filter water quality
during the first year. EPA will evaluate the efficiency of the filters to remove Site-related
contaminants and replace filter media as needed.· EPA may con_duct some additional testing at
these wells as a part of the long term sampling of the -groundwater plume. The homeowners have
agreed to assume responsibility for continued maintenance of the filters after the first year.
Remaining activities to be completed by the EPA contractor include periodic adjustments
and/or modifications to the carbon filters, including changing of filter media and testing to
maintain optimum performance during the first year after installation. Also, as outlined above,
implementation of the long term groundwater monitoring plan will also take place. EPA and the
State have not yet concurred on the operational and functional (O&F) period, however, the City
of Gastonia has agreed in writing to assume operation and maintenance responsibility for the
water lines at that time. The homeowners have agreed to assume primary responsibility for
operation and maintenance of the water service lines and of the five carbon filters.
No activities using removal authority were conducted at this Site.

ID. DEMONSTRATION OF CLEANUP ACTMTY QUALITY ASSURANCE AND
QUALITY CONTROL
EPA and the State reviewed the remedial action contract and construction for compliance
with quality assurance and quality control (QNQC) protocols. Construction activities at the Site
were determined to be consistent with the ROD, RD plans and specifications, and the RD and RA
stateme,its of work issued to the RAC contractor. Plans and specification for the water line
construction were also made consistent with City of Gastonia water system requirements and
State requirements for erosion control.
All confirmatory inspections, testing, and evaluations of materials and workmanship were
performed in accordance with the construction drawings and technical specifications.
Construction quality assurance was performed by the RAC contractor, which maintained a
constant on-site presence during the water line construction. The City of Gastonia construction
inspector maintained a part-time on-site presence and oversaw the water line testing required for
acceptance by the City. The EPA project manager visited the Site during construction activities to
review construction progress and adherence to the QNQC protocols, safety requirements,
drawings, and specifications. Changes were properly documented and will be reflected in the as-
built plans.
The Quality Assurance Project Plan (QAPP) incorporated all EPA and State QNQC
procedures and protocol. EPA procedures and analytical methods were used for all samples
collected during RD and RA activities. EPA and the ·state determined that analytical results are
accurate to the degree needed.
Sampling for the November 1999 natural attenuation study was conducted as specified in
the USEP A, Region 4, Science and Ecosystem Support Division, Environmental Investigations
Standard Operating Procedures and Quality Assurance Manual, May 1, 1996. All analyses were
conducted as specified in the USEP A, Region 4, Science and Ecosystem Support Division,
Analytical Support Branch Operations and Quality Control Manual, December 1997.

V. SUMMARY OF REMEDIATION COSTS
The original cost estimate to implement the remedial action described in the ROD was
$3,873,299 (net present worth). Costs were estimated for an anticipated 30-year time period
(assuming groundwater monitoring may need to continue that long) and a discount rate of3.5 %
was used ii) th{ ROD estimate. More detailed cost estimate documentation can be found in the
Feasibility Study for the Site.
The estimated final RA cost for the water lines, carbon filters and well abandonment is
$725,000. This does not include the long-term groundwater monitoring, for which EPA has yet
to contract. It is estimated that the final total present worth costs for the RA will be significantly
less than the ROD estimate.

VI. FIVE-YEAR REVIEW
Upon completion of this remedy no hazardous substances will remain at the Site above
levels that allow unlimited use and unrestricted exposure after the completion of the remedial
action. However, it is expected that it will take greater than five years to achieve the groundwater
clean-up goals. As provided in the current guidance on Five Year Reviews: OSWER Directive
9355. 7-92, Structure and Components of Five-Year Reviews, May 23, 1991, OSWER Directive
9355.702A, Supplemental Five-Year Review Guidance, July 26, 1994, and the Second
Supplemental Five-Year Review Guidance, December 21, I 995, EPA will conduct a five-year
review for this Site. The Five-Year Review Report will be completed prior to September 27,
2005 (five years after completion of this Preliminary Close Out Report).

EXPLANATION OF SIGNIFICANT DT.FFERENCE
DA VIS PARK ROAD TCE SITE
GASTON COUNTY, NORTH CAROLINA
NCD986175644
1.0 lNTRODUCTION
Section l l 7(c) of the Comprehensive Environmental Response, Compensation, and
Liability Act of 1980, 42 U.S C. § 96 l 7(c), as amended (CERCLA), and Section 300.435(c)(2)(i)
of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), 40 C.F. R. Part
300.435(c)(2)(i), require that the Environmental Protection Agency (EPA) publish an Explanation
of Significant Difference (ESD) when significant changes in a Superfund remedy occur after the
Record of Decision (ROD) is signed. The purpose of this ESD is to notify all parties of concern
that the EPA, as the lead agency, with the support of North Carolina Department of Environment
and Natural Resources (NC DENR), is announcing a significant change to the remedy for the
Davis Park Road TCE Site (Site), located in Gaston County, North Carolina. The ROD for this
Site was signed on September 29, I 998. This change is being made based on information
collected during the Remedial Design and the Remedial Action (RD/RA). The information
collected indicates that natural attenuation will achieve groundwater clean-up goals for this
Site, and that implementation of an active groundwater clean-up remedy is not needed.
The information collected also indicates that it may take longer than previously estimated
for groundwater to reach remedial clean-up goals.
As required by Sections 300.435(c)(2)(i)(A) and 300.825(a)(2) of the NCP, a copy of this
ESD will be added to the Site Administrative Record and Information Repository. The
Administrative Record and Information Repository can be found in the Gaston County Public
Library in Gastonia, North Carolina, and in the US EPA Region 4 Record Center in Atlanta,
Georgia. Both addresses are provided in Section 7.0 of this document. The public is encouraged
to review the Administrative Record and the Information Repository at either of these locations.
2.0 SITE HISTORY, CONTAMINATION, AND SELECTED REMEDY
The Davis Park Road TCE Site includes approximately 20 acres o[residential hollies and
private businesses in unincorporated Gaston County, southwest of the City of Gastonia. The Site
consists of a contaminated soil area that was reportedly behind an automobile transmission shop
located at 2307 Davis Park Road, and a plume of contaminated groundwater that emanates from
this property and extends south along Davis Park Road to Blackwood Creek. The plume of
contaminated groundwater underlies residences at the Site along the plume's entire horizontal
extent. A majority of homes within the Site area obtain their water from private or community
wells. Tetrachloroethene (PCE), Trichloroethene (TCE), I, 1-Dichloroethene (I, 1,-DCE),
Chloroform, and Methyl-ter-butyl ether (MTBE) are the groundwater contaminants of concern
identified in the ROD.
• • 2
The ROD also included natural attenuation of groundwater contaminants as an integral
part of the remedy for the Site, and contains an estimate of seven years to achieve remedial goals
through natural attenuation. The ROD specified that groundwater sampling, including parameters_
necessary to complete a natural attenuation study, would be conducted as part of the RD phase of
this project, and that a natural attenuation review would be conducted and a report prepared. The
ROD contained a contingency remedy, to add pumping and active treatment of the contaminated
groundwater to the selected remedy, if data collected during the natural attenuation study did not
substantiate the occurrence of natural attenuation.
The Rl/FS concluded that soil contamination at the probable source area for the
groundwater plume was no longer at levels warranting further action. It was also concluded that
migration of the groundwater plume toward Blackwood Creek would not result in a measurable
release of Site-related contaminants to the creek.
3.0 BASIS FOR THIS DOCUMENT AND DESCRIPTION OF
SIGNIFICANT DIFFERENCES
A sampling effort for the natural attenuation study was conducted in November 1999. A
thorough review of the data, review of all historical data, and predictive analyses were conducted
and summarized in an EPA Region 4 Memorandum Report dated September 25, 2000. The
report focuses on TCE and PCE as the critical contaminants of concern.
TCE concentrations are projected to diminish to less than the 5 ug/1 Safe Drinking Water
Act Maximum Contaminant Level (MCL) in 12 years for the worst (slowest) estimate. Data from
most wells suggest that TCE concentrations in most wells will be less that the MCL in about 5
years. Remedial goals for this Site are based on North Carolina's groundwater standard for TCE,
which at 2.8 ug/1 is lower than the MCL. A worst case estimate is that it will take 26 years to
achieve concentrations below that level in all parts of the plume. However since the average
groundwater travel time to Blackwood Creek is estimated at 13 years, this estimate is probably
overly conservative.
PCE concentrations are expected to diminish to less than the MCL (5 ug/1) in 15 years
assuming extreme worst case conditions. The remedial goal for PCE for this Site, 1.0 ug/1, is
based on North Carolina's groundwater standard and the minimum detection level. A worst case
estimate is that it will take 43 years to achieve concentrations below that level in all parts of the
plume. Since the estimated contaminant migration rate from the area of highest PCE
contamination to Blackwood Creek is approximately 7 to IO years, this indicates that our worst
case estimates for PCE may also be overly conservative.
The estimated time frames for natural attenuation are longer than projected in the Record
of Decision. However the conclusion that natural attenuation will achieve remedial goals, and
that contaminant levels in groundwater will reach Safe Drinking Water Act Maximum
Contaminant levels in an even shorter time frame, remains consistent with the ROD and eliminates·
the need for the contingency remedy. Cost estimates are not changed based on this significant
difference. The estimated costs in the 1998 ROD are based on 30 years of groundwater
monitoring.
• • 3
EPA currently plans to monitor groundwater from identified private wells and monitoring
wells quarterly for the next two to three years, for wells with limited historical data, and annually
for all wells, until remedial goals are demonstrated to be achieved. Monitoring frequency will be
reevaluated as needed. Sample collection and data review will follow EPA' s guidelines for .
monitored natural attenuation.
4.0 SUPPORT AGENCY COMMENTS
The NC DENR Superfund Section was given the opportunity to review this ESD. They
concur with this modification to the remedy.
5.0 STATUTORY DETERMINATIONS
The modified remedy satisfies CERCLA Section 121. EPA and NC DENR believe that
the changes made to the remedy have not decreased the protectiveness for human health and the
environment, comply with Federal and State requirements that are applicable or relevant and
appropriate to the Remedial Action, and are cost-effective. In addition, the revised remedy
utilizes permanent solutions and alternative treatment technologies to the maximum extent
practicable for this Site.
6.0 PUBLIC PARTICIPATION COMPLIANCE
As required by sections 300.435(c)(2)(i)(A) and 300.825(a)(2) of the NCP, this ESD will
be added to the Administrative Record for the Davis Park Road TCE Superfund Site. Copies of

• Collection of additional information during the first year of the Remedial Design effort in
order to support the predicted dispersion and intrinsic biodegradation rates for the
contaminated groundwater.
The ROD also contained a contingency remedy which would be implemented if the data
collected during the natural attenuation study did not substantiate that natural attenuation would
achieve remedial goals. The contingency remedy specified groundwater pumping, using a
minimum of three extraction wells, with treatment of contaminated groundwater using activated
carbon.
The RI/FS concluded that soil contamination at the probable source area for the
groundwater plume was no longer at levels warranting further action. It was also concluded that
migration of the groundwater plume toward Blackwood Creek would not result in a measurable
release of Site-related contaminants to the creek.
Remedial goals for groundwater were selected as the most conservative of the chemical-.
specific ARARs or the health-based risk goals and are:

On July 23, 1999, EPA processed a work assignment under one of our available Remedial
Action Contracts (RAC) for the RD. As part of the RD a final list of homes to be connected to
the public water supply system or to receive carbon filters was determined. The remedial design
of the water lines and carbon filters was determined to be substantially complete in December
1999.
After obtaining funding, on February 16, 2000, EPA processed a work assignment under
the same Remedial Action Contract to begin the Remedial Action (RA). Actual on-site
construction of the water lines began on May I 5, 2000.
RA construction included approximately 5625 linear feet of 12-inch, 8-inch and 6-inch
ductile iron pipe, plus related service lines and appurtenances. Roads, rights-of-way, and private
properties were returned to undisturbed conditions. A total of sixty three (63) residences were
connected to the City of Gastonia water system and are now receiving water from that system.
EPA installed carbon filters at five (5) residences where the homeowners would not agree to be
connected to the public water supply system. Two homeowners with private wells in the Site area
elected not to be connected to the public water supply system or receive a filter system ( one of
whom had initially agreed to receive public water). Water service is available to these two homes
via the EPA constructed water lines should the homeowners change their minds in the future,
however the physical connection would be.their responsibility. Other changes from the RD
included the addition of one home not previously identified as impacted by the Site, the deletion
of one home already connected to City water, and the deletion of two homes connected to a
community well not impacted by the Site.
EPA also physically abandoned 19 private wells by plugging with a cement grout. EPA
physically abandoned only those wells where the homeowners agreed to have them plugged. With
the conditional concurrence oflocal Public Health Department, other wells were disconnected
from the homes but left operational for watering gardens, etc.
A sampling effort for the natural attenuation study was conducted in November 1999. A
thorough review of the data, review of all historical data, and predictive analyses were conducted
and summarized in an EPA Region 4 Memorandum Report dated September 25, 2000. The
report focuses on TCE and PCE as the critical contaminants of concern.
TCE concentrations are projected to diminish to less than the 5 ug/1 Safe Drinking Water
Act Maximum Contaminant Level (MCL) in 12 years for the worst (slowest) estimate. Data from
most wells suggest that TCE concentrations in most wells will be less that the MCL in about 5
years. Remedial goals for this Site are based on North Carolina's groundwater standard for TCE,
which at 2.8 ug/1 is lower than the MCL. A worst case estimate is that it will take 26 years to
achieve concentrations below that level in all parts of the plume. However, since the average
groundwater travel time to Blackwood Creek is estimated at 13 years, this estimate is probably
overly conservative.
• •
4
PCE concentrations are expected to diminish to less than the MCL (5 ug/1) in 15 years
assuming extreme worst case conditions. The remedial goal for PCE for this Site, 1.0 ug/1; is
based on North Carolina's groundwater standard and the minimum detection level. A worst case
estimate is that it will take 43 years to achieve concentrations below that level in all parts of the
plume. Since the estimated contaminant migration rate from the area of highest PCE
contamination to Blackwood Creek is approximately 7 -IO years, this indicates that our worst
case estimates for PCE may also be overly conservative.
The estimated time frames for natural attenuation are longer than, but basically consistent
with the ROD assumption and eliminates the need for the contingency remedy. EPA currently
plans to monitor groundwater from identified private wells and monitoring wells quarterly for the
next two to three years, for wells with limited historical data, and then annually thereafter for all
wells, until remedial goals are demonstrated to be achieved. Monitoring frequency will be
reevaluated as needed.
The City of Gastonia has agreed in writing to assume responsibility for operation and
maintenance of the water lines, up to the water meter, after EPA completes the remed.ial action
construction. The homeowners will become responsible for maintenance of their service lines and
pressure reducing valves. EPA has agreed to maintain the five filter systems for a minimum of
one year from installation, including periodic testing of the pre-and post-filter water quality
during the first year. EPA will evaluate the efficiency of the filters to remove S,ite-related
contaminants and replace filter media as needed. EPA may conduct some additional testing at
these wells as a part of the long term sampling of the groundwater plume. The homeowners have
agreed to assume responsibility for continued maintenance of the filters after the first year.
Remaining activities to be completed by the EPA contractor include periodic adjustments
and/or modifications to the carbon filters, including changing of filter media and testing to
maintain optimum performance during the first year after installation. Also, as outlined above,
implementation of the long term groundwater monitoring plan will also take place. EPA and the
State have not yet concurred on the operational and functional (O&F) period, however, the City
of Gastonia has agreed in writing to assume operation and maintenance responsibility for the
water lines at that time. The homeown~rs have agreed to assume primary re;ponsibility for
operation and maintenance of the water service lines and of the five carbon filters.
No activities using removal authority were conducted at this Site.

ID. DEMONSTRATION OF CLEANUP ACTIVITY QUALITY ASSURANCE AND
QUALITY CONTROL
EPA and the State reviewed the remedial action contract and construction for compliance
with quality assurance and quality control (QNQC) protocols. Construction activities at the Site
were determined to be consistent with the ROD, RD plans and specifications, and the RD and RA
statements of work issued to the RAC contractor. Plans and specification for the water line
construction were also made consistent with City of Gastonia water system requirements and
State requirements for erosion control.
All confirmatory inspections, testing, and evaluations of materials and workmanship were
performed in accordance with the construction drawings and technical specifications.
Construction quality assurance was performed by the RAC contractor, which maintained a
constant on-site presence during the water line construction. The City of Gastonia construction
inspector maintained a part-time on-site presence and oversaw the water line testing required for
acceptance by the City. The EPA project manager visited the Site during construction activities to
review construction progress and adherence to the QNQC protocols, safety requirements,
drawings, and specifications. Changes were properly documented and will be reflected in the as-
built plans.
The Quality Assurance Project Plan (QAPP) incorporated all EPA and State QNQC
procedures and protocol. EPA procedures and analytical methods were used for all samples
collected during RD and RA activities.· EPA and the State determined that analytical results are
accurate to the degree needed.
Sampling for the November 1999 natural attenuation study was conducted as specified in
the USEP A, Region 4, Science and Ecosystem Support Division, Environmental Investigations
Standard Operating Procedures and Quality Assurance Manual, May I, I 996. All analyses were
conducted as specified in the USEPA, Region 4, Science and Ecosystem Support Division,
Analytical Support Branch Operations and Quality Control Manual, December 1997.

V. SUMMARY OF REMEDIATION COSTS
The original cost estimate to implement the remedial action described in the ROD was
$3,873,299 (net present worth). Costs were estimated for an anticipated 30-year time period
(assuming groundwater monitoring may need to continue that long) and a discount rate of3.5 %
was used in the ROD estimate. More detailed cost estimate documentation can be found in the
Feasibility Study for the Site.
The estimated final RA cost for the water lines. carbon filters and well abandonment is
$725,000. This does not include the long-term groundwater monitoring, for which EPA has yet
to contract. It is estimated that the final total present worth costs for the RA will be significantly
less than the ROD estimate.

VI. FIVE-YEAR REVIEW
Upon completion of this remedy no hazardous substances will remain at the Site above
levels that allow unlimited use and unrestricted exposure after the completion of the remedial
action. However, it is expected that it will take greater than five years to achieve the groundwater
clean-up goals. As provided in the current guidance on Five Year Reviews: OSWER Directive
9355. 7-02, Structure and Components of Five-Year Reviews, May 23, 1991, OSWER Directive
9355.702A, Supplemental Five-Year Review Guidance, July 26, 1994, and the Second
Supplemental Five-Year Review Guidance, December 21, 1995, EPA will conduct a five-year
review for this Site. The Five-Year Review Report will be completed prior to September 27,
2005 (five years after completion ofthis Preliminary Close Out Report).

Phil,
I have reviewed the results from the latest sampling effort at the Davis Park R9ad site as
you requested. My review focused only on issues related to site characterization and the
hydrogeology of the site and does not address risk assessment issues. These comments
are intended to:
1.) summarize the history of groundwater contamination at the site and areas down
gradient from the site within the framework of a groundwater concept model; .
2.) evaluate the progress of natural attenuation which effected the groundwater
plume during the 1990s;
3.) provide the background data necessary to justify the remedial measures
selected for implementation at the site;
4.) project clean-up times by natural attenuation;
5.) recommend wells to be sampled during a groundwater monitoring program.
GENERAL COMMENTS
Sample results for which the laboratory analysis were "Non-Detect", are plotted at 1
microgram/liter (µg/L) on the graphs which accompany this memo to show that something
happened on that date. This evaluation was performed using results from the November,
1999 sampling event, plus data from earlier events dating back to 1990, to evaluate
contaminant trends versus time . .Data from the most recent sample event was down-
loaded from the EPA Region 4 R4LIMS. Data from all other, older events were translated
from a spreadsheet provided by the consultant, or typed from reports in tables. The
original laboratory reports have not been examined. The concentrations for PCE and TCE
found in groundwater since 1990 were used in this evaluation. Observations regarding the
distribution of these chlorinated solvents are supported by dissolved oxygen data collected
on November 15, 1999 (USEPA, 2000, Table 7). Other natural attenuation data collected
on November 15, 1999 is available. These data may be useful in evaluating natural
attenuation processes, but only after more observations have been collected.

The discussion of groundwater contamination is organized around two groups of wells.
Wells 49, 121 and 131 are located in the•vicinity of the suspected source area. These
wells are up gradient from the second group of wells, which includes wells 232, 239 (CW5),
285 (PW1 ), plus the MW2. well pair and MW5S. The evaluation of historic trends in
groundwater quality presented in this memo is one of three lines of evidence
recommended in the EPA Guidelines for evaluating Monitored Natural Attenuation (MNA).
A groundwater monitoring program should be established to confirm that contaminant
degradation continues as predicted in this memo.
The locations of all wells described in this report are shown in the Remedial Investigation
(RI) report by EPA's contractor, Weston Inc., dated July, 1998 Figure 3-1 and Figure 5-6.
However, neither of these figures shows all of the wells, and some wells are called by
different names on the two figures in the same report. The most common names are used
in this memo where possible.
Clean-up time estimates presented in this memo are based on the Federally.mandated
Maximum Contaminant Levels (MCL) for drinking water because water of this quality could
be considered suitable for delivery to residents on community water supplies. The MCL
for both of the contaminants of concern at this site, trichloroethene (TCE) and
tetrachlorethene (PCE), is 5 µg/L. The remedial groundwater clean-up goals prescribed
in the Record of Decision (ROD) for this site are goals of 2.8 µg/L for TCE and 1 µg/L for
PCE. These concentrations are similar to the detection limits commonly used for analyses
of these contaminants. Times at which groundwater contaminant concentrations are
estimated to reach these more pristine conditions, based on conservative assumptions,
are 2 to 3 times longer than the times estimated in this memo to be required to achieve the
MCL.
GROUNDWATER CONCEPT MODEL
The site is located on. a ridge on or near a groundwater flow divide between Blackwood
and Crowders Creeks. The creeks flow southward on both sides of the ridge, and
groundwater level contour maps indicate that groundwater flows from the source area in
all directions except north (RI Figures 4-7 to 4-10). Numerous domestic water supply wells
are located in the area surrounding the suspected source, and scime wells south and
south-southeast of the site are known to have been contaminated.
Contamination appears to be flushing through the aquifer. Groundwater samples from
wells near the source area have not been contaminated in recent sample events, while
concentrations in wells located south of the source area, closer to the natural discharge
area, have increased. The data available suggests that the source has been depleted or
removed from the unsaturated zone, and that residual groundwater contamination is
migrating toward natural and man-made discharge areas.

Groundwater flows through an upper saprolite layer, which consists of silty sand and
clayey sand with varying percentages of gravel. The saprolite is 10-80 feet thick and is
underlain by partially weathered and unweathered granite. The granite is fractured, and
fracture traces typically are oriented NE/SW. The fracture trend is similar to the orientation
of the ridge and the creeks. The depth to water is near zero in topographically low areas
near the creeks, and as much as 42 feet beneath topographic highs.
The average groundwater velocity is estimated to be 197 ft/year (Feasibility Study (FS),
p.7-16), based on the observed hydraulic gradients and hydraulic conductivities
determined from slug tests and a pumping test. The total organic carbon content of both
the saprolite and granite are very low (FS, p. 7-17), therefore, the retardation factor for the
contaminant of concern, TCE, is estimated to be very low. Contamination is expected to
move at rates similar to uncontaminated groundwater. The estimated con tam in ant velocity
is 188 ft/year (FS, p.7-17). The typical flow-path length from the source area to the
discharge areas, where groundwater enters surface water, is approximately 2,500 feet (RI
Figure 4-7 to 4-10).
Based on length of the typical flow path and the estimated annual contaminant velocity, the
average contaminant travel time to the creeks is approximately 13 years. If contamination
is assumed to have originated in the mid-1980s (FS, p.7-18), and if the contaminant
velocity estimates are correct, much of the contaminant has already completed travel along
the flow path to Blackwood Creek. This may explain the absence of contamination in the
most recent source area groundwater samples, and the absence of degradation products,
such as vinyl chloride, in the groundwater samples anywhere in the flow system. The
absence of daughter products may also be due, in part, to the geology and topography of
the site, which are likely to help maintain relatively high dissolved oxygen levels observed
in November, 1999 (USEPA, 2000, Table 7). The combination of oxygen rich water from
precipitation, which moves vertically downward in recharge areas beneath ridges, and the
relatively rapid groundwater movement through this aquifer create conditions unfavorable
for the build-up of TCE daughter products. In particular, vinyl chloride, the TCE daughter
product with the lowest MCL, is easily oxidized and typically is not found in aerobic
environments. 1
SUMMARY OF OBSERVATIONS AND RECOMMENDATIONS
1. TCE contamination in groundwater, which was observed in the suspected source
area during the early 1990s, has diminished. In November, 1999, TCE was either
not detected or was less than the MCL in two of the three wells (wells 49 and 121)
which were contaminated when the site was first discovered. The third well, Well
131 was not sampled in November, 1999.
2. Although TCE concentrations in the source area wells vary, and some future
samples may still show concentrations of TCE, the suspected source for TCE
appears to be depleted.

• •
3. TCE has migrated down gradient from the source area. Wells which were not
contaminated with TCE in the early 1990s (wells 181 and 285) are now
contaminated with TCE. The concentration trends appear to have peaked and may
be beginning a gradual decline as natural attenuation reduces contaminant
concentrations.
4. TCE concentrations in monitoring wells installed near the natural groundwater
discharge area (MW2S and MW2D) may not have peaked yet. These wells are
farthest down gradient from the source and closest to the natural groundwater
discharge area. These wells would be expected to be the last wells effected by
contaminated groundwater as it is flushed along the natural pathway from recharge
area to discharge area. The peak concentrations which will be observed in these
wells will be less than has been observed in wells 181 and 285 (PW1 ), due to
natural attenuation with travel time and distance from the source.
5. PCE was found in soils in the source area, has never been found in groundwater
in the suspected source area (wells 49, 121 and 131) since the site was discovered
in 1990. If PCE was ever present in groundwater in this area, it had degraded or
migrated away before the first groundwater samples were collected. PCE is present
in groundwater down gradient from the suspected source area.
6. PCE concentrations in groundwater from well 239 (CW5) exceeded the MCL for
PCE in 1990 and remained above the MCL in January, 1998. PCE concentrations
are not diminishing at rates which can be simulated by a first-order decay
coefficient, as is often observed when contamination is being reduced by natural
attenuation. Instead, PCE concentrations are declining at a much ·slower rate. The
slow rate of decline in PCE concentrations at well 239 suggests that the source for
PCE may not be depleted. Well 239 (CW5) was not sampled in November, 1999,
so recent concentrations in this well are unknown. If PCE concentrations in well
239 (CW5) continue to decline at the rate observed between 1990 and 1997, the
concentration· of PCE in well 239 should be near the MCL by the year 2015.
7. TCE concentrations in well 232 and MW5S suggest that contamination is migrating
toward the south, down gradient to Blackwood Creek, and not directly south-
southeast toward the MW2 well pair. The concentrations of TCE in these wells
have been near the MCL and may be increasing. Contaminant concentrations may
rise in these wells, particularly MW5S, but the concentrations are not expected to
exceed those observed farther up gradient.
8. TCE contamination in groundwater appears to be diminishing at rates which can be
approximated by a first-order decay coefficient. TCE concentrations are projected
to diminish to less than the MCL (5 µg/L) in 12 years for the worst (slowest)
estimate. Data from most wells suggests that TCE concentrations will be less than
the MCL in about 5 years.
9. Wells which should be monitored in the future include 49, 121, 131, 172,181,230,
232, 239, 285, MW1 S, MW1 D, MW2S, MW2D, MW5S. EPA guidelines for
evaluating Monitored Natural Attenuation should be followed.

• •
10. EPA guidelines regarding MNA recommend quarterly monitoring until seasonal
variations in long-term trends are established. However, wells at this site have
been sampled intermittently for as long as 10 years and the long-term trends
identified in this memo appear to be greater than potential seasonal variations.
Wells which have been contaminated in the past but have been uncontaminated in
recent samples should be sampled annually. Wells which are contamin_ated
currently should be sampled quarterly for one year, and annually thereafter, except
for wells where an increasing trend in contaminant concentrations is apparent.
Wells with increasing contaminant concentrations, and wells where contaminant
concentrations are expected to become contaminated should be sampled quarterly
for at least one year, after which, the sample frequency should be re-evaluated
based on observed contaminant trends, seasonal variations and estimated travel
times to the next down gradient monitoring wells. Based on groundwater flow
directions and contaminant distributions shown in RI Figures 5-3 and 5-4, TCE
concentrations are expected to increase in the vicinity of well 172. Both TCE and
PCE concentrations are expected to increase in wells southeast of. well 239.
Smaller increases in TCE and PCE may be observed in wells south and south west
of well 239. TCE and PCE concentrations increased in well 232 between 1996 and
1999. These increases will occur as known contamination moves through the
groundwater flow system toward the natural discharge areas at Blackwood Creek.
11. Well depths have not been determined for many of the wells which have been
sampled in the vicinity of the Davis Park Road site. The depth to water has not
been measured routinely, so variations in groundwater flow directions are unknown ..
Relationships between contaminated wells and suspected source areas can not be
defined with the certainty often acquired at other sites.
The following sections of this memo describe the data which supports the observations
listed above, and presents plots of sample results versus time which demonstrate these
observations.
TCE TRENDS VERSUS TIME (Wells 49. 121 and 131. Figure 1 & 21
TCE and PCE have been the contaminants of concern (COCs) at this site. Figure 1 shows
the TCE concentration in these wells 49, 121, 131 over time. These wells are located near
the suspected source area, and were found to be contaminated in the earliest sample
events. The TCE concentration in well 131, the most down gradient of the 3 wells, was
greater than the MCL in 1990. The TCE concentration in well 131 rose to levels similar to
those observed in well 49 and 121 between 1990 and January, 1993, suggesting that
contaminant migration from the vicinity of the suspected source area \"✓as occurring.
Figure 1 shows some irregularities in the samples collected in 1993 and 1994. TCE was
not detected in every sample from wells 49, 121 and 131 during this period. These
irregularities complicate the evaluation of Natural Attenuation and must be described
before other trends are evaluated. It is important to note that when TCE was not detected ·
Page 5 September 22, 2000 (1 :35PM) F:IPROJECTS\DAVISPARIRPMMAIL\recomend5.wpd
• • in one well it was not detected in any of these three wells. When TCE was detected i~
one well, it was detected in all three wells. When _detected, TCE was present a
concentrations similar to the concentration detected In previous samples. The time
between detect and non-detect samples is sometimes as little as 2 weeks. -
The "W' pattern during 1993, shown on Figure 1, is result of this intermittent detection of
TCE at wells 49, 121 and 131. Because these wells are located at different distances from
the source, it seems unlikely that 3 wells in different parts of a natural flow system w?uld
all be non-detect, all at the same time on so many days, yet return to previous
concentrations all at the same time on other days. It seems more likely that some factor
in the way the samples were collected or handled after collection resulted in a loss of
volatile organic components from the samples. The results of the 1993/94 samples when
TCE was not detected probably are not valid, but the cause has not been addressed in any
of the investigations at the site.
Figure 2 shows that when the "W is ignored, contaminant concentrations in wells 49, 121
and 131 have diminished since 1990, generally following a trend which can be·
approximated by drawing a straight line between the highest sample and the most recent •
sample for each well. By the 1998 and 1999 sample events, concentrations in these wells i
had declined and were at or near the MCL. This downward trend toward the MCL
suggests that the source has been depleted over time. Based on nearly 1 O years of
observation, TCE concentrations are expected to continue to diminish, and eventually TCE
concentrations in these \rvells 'Nill be consistently belovv' the l\1CL.
The degradation trend is irregular as shown by the sharp rise in TCE concentrations in Fall
of 1998 in wells 121 and 131 (Figure 2). After the sharp rise in TCE concentrations in the
Fall of 1998, the TCE concentration in well 121 declined to concentrations below the M~L
by November, 1999. Well 131 was not sampled in November, 1999, but the concentration
probably declined below the MCL also.
The variation in apparent degradation rates may be due to variations in rainfall, changes
in the depth to water at the time of sampling or other factors which may cause resid~al
contamination to be leached into the ground water system occasionally . .However, thEjlre
may be other reasons. For example, note that in October, 1998, the TCE concehtration
in well 131 rose from 1 µg/L to 16 µg/L in just 3 days. The two samples were analyzed py
different laboratories, and presumably collected by different field teams using different
procedures. The intermittent occurrence of MCL exceedances in these wells make
prediction of clean up times difficult. However, despite the irreg~larities, the over all trend
in TCE concentrations for 10 years of record is downward. Clean up time estimates in this
memo are based on this observed trend. In all figures after Figure 1, the line between
sample events is broken at the suspect samples from 1993/94.

TCE TRENDS VERSUS TIME (Wells 181, 239 and 285 IPW1I, Figure 3 & 41
Wells 181 and 285 (PW1) are located relatively far down gradient toward the natural
groundwater discharge area. These wells were not contaminated in the earliest sample
events (Figure 3). The maximum concentrations observed in these wells are similar to the
concentrations shown on Figures 1 and 2 for the same time period (Figure 4). These
observations indicate that the plume has moved down gradient from the source area
toward the natural discharge area at Blackwood Creek. The TCE concentrations have
been diminished by natural attenuation processes with time and distance from the source,
so concentrations in the down gradient area are unlikely to ever be as high as those once
observed in the source area.
PCE TRENDS VERSUS TIME (Wells 49. 121 and 1311
PCE was detected in soil in the source area, but has never been detected groundwater
samples from wells 49, 121, 131, located near the suspected source, but only in wells
located farther down gradient. If PCE once was present in groundwater beneath the
source area, it was removed by migration or natural attenuation prior to 1990. The
absence of PCE in groundwater from the suspected source area during the 1990s seems
inconsistent with the slow degradation of PCE in wells further down gradient. However,
the EPA consultant has never reported that another source for PCE might be present.
Regardless of the source for the PCE, it is commingled with the TCE, it is degrading, and
it is migrating toward the natural discharge area. PCE concentrations down gradient from
the source area are presented in Figure 5 and described later in this memo.
PCE TRENDS VERSUS TIME (Wells 232, 239 (CW5), 285 (PW1). MW2 and MW5,
Figure 51
PCE was detected in weU239 (CW5) in 1990. However, neither PCE nor TCE were
detected in the June 1992 sample from well 239 (CW5). The line between the June 1992
sample from well 239 (CW5) and samples before and after this date is broken (Figure 5).
The PCE concentration in well 239 (CW5) has been .1 0 to 20 µg/L in all other samples.
The results from the June 1992 samples from well 239 (CW5) probably are not valid.
PCE well 239 (CW5) has diminished only slightly since 1990 (Figure 5). No other:well at
this site has ever shown PCE concentrations as high as those observed in well 239 (CW5).
Well 239 (CW5) was not sampled in November, 1999, so recent concentrations in this well
are not known. Trends in contaminant concentrations in this well are described later in this
memo (Figures 10, 13 and 15).
Well 285 (PW1) was not contaminated in 1990, but was contaminated in excess of the
MCL for PCE by 1996 (Figure 5). The results from the November, 1999 sample in well 285
(PW1) showed PCE concentrations continue to be above the MCL for PCE. This well is
relatively far down gradient from the suspected source area. These data suggest that PCE
contamination has moved into the vicinity of well 285 (PW1) from the up gradient area near
wel! 239 (C\AJ5).

PCE concentrations are rising in well 232. This well has been considered to be on the
edge of the PCE plume in previous sample events (Weston RI, Figure 5-3). A slow,
downward trend in PCE concentrations appears to be occurring in all other wells (Figure
5), but as shown later in this memo, the rate of decline is less than would be expected by
natural attenuation through reductive dechlorination. This process, which includes the
normal degradation of PCE to TCE, DCE, vinyl chloride and ultimately ethene, can usually
be approximated by a first-order decay coefficient.
PCE degradation in well 239 is proceeding much less rapidly than the slowest degradation
rate given in published references (Howard and others, 1991 ). The source of the PCE
may not be depleted. PCE concentrations may rise in the MW2 and MW5 wells. These
wells are farthest down gradient and closest to the natural discharge area at Blackwood
Creek. If a source for residual PCE is present, degradation rates may increase in the
future once the source is depleted.
TCE TRENDS VERSUS TIME (Wells 232. 239 (CW5l, 285 (PW1l. MW2 and MW5.
Figure Sl
Figure 6 shows the TCE concentrations in the same wells as shown in Figure 5. The TCE
concentration in well 239 (CW5) has been 30 to 60 µg/L in all samples except for the
sample in mid-1992. Overall, a downward trend is apparent in well 239 (CW5). Farther
down gradient, concentrations peak at consecutively lower levels with travel time and
distance from the source. A comparison between Figure 5 and 6 shows that the trends in
TCE and PCE concentrations are generally the same for each \a.rel!.
From Figure 5-6 in the Weston RI, well 239 (CW5) is the most up gradient well
contaminated with PCE, well 285 (PW1) is down gradient, and the MW2 wells are most
down gradient. Both of the MW2 wells are contaminated with TCE and PCE, but to date,
concentrations have _been near the MCLs. The TCE and PCE concentrations may
increase in the MW2 and MW5 wells during the next two years. This indicates migration
of contamination from up gradient areas toward the natural discharge area, and is
consistent with the observed diminishment of PCE and TCE concentrations with trav'el time
and distance from the source area. TCE and PCE concentrations in MW2S and MW2D
are not expected to exceed those observed in well 285 (PW1) between 1996 and 1999.
CLEAN UP TIME ESTIMATES
The natural attenuation of organic contamination in groundwater has been observed to
diminish with time and distance from a source, often at a rate which can be approximated
by a first-order decay coefficient. These coefficients are commonly expressed in terms of
a half-life, measured in days. For each chemical (TCE and PCE), the shortest and longest
half-life from the Handbook of Environmental Degradation Rates (Howard and others,
1991 ), plus two additional degradation rates chosen to best fit the observed data, are
superimposed on the data presented in Figures 1-6.
Page 8 September 22, 2000 ( 1: 18PM) F:\PROJECTS\DAVISPAR\RPMMAIL\recomend5.wpd
• •
Published half-lives for TCE in groundwater range between approximately 10 months and
4.5 years. Published half-lives for PCE range between 1 and 2 years. Clean up times are
estimated by taking the data presented in Figures 1-6 of this memo, and superimposing
4 half-lives on the graphs. The different "Assumed Initial Concentrations" shown on each
graph represent the concentrations assumed to be present in that portion of the plume on
January 1, 1990. These concentrations are selected so that concentrations observed in
the wells during the 1990s will be less than the concentration calculated from the Assumed
Initial Concentration using the longest half-life.
Figure 7 shows that the TCE contamination in well 49 degraded at rate equivalent to a half-

Figure 8 shows that the TCE contamination in well 121 has degraded at rate equivalent
to a half-life of about 650 days, except for the Fall, 1998 sample. From Figure 8, a "worst
case" for the time required for clean-up by natural attenuation is approximately 12 years
(year 2012). This estimate is based solely on the relatively high concentration of TCE
reported in this well from the sample of October 21, 1998. However, 13 months later, the
November, 1999 sample was already below the MCL. Based on the November, 1999
sample and a degradation trend at an apparent half-life of 650 days, concentrations in this

Figure 9 shows that the TCE contamination in well 131 has degraded at rate equivalent
to a half-life between 300 and 500 days, except for the October 21, 1998 sample. Note
that the TCE concentrations in both the June 25, 1998 and the October 19, 1998 samples
from this well were 1 µg/L. This well was not sampled in November, 1999. From Figure
9, a "worst case" for the time required for clean-up by natural attenuation is approximately
5 years (year 2005).
Figure 1 O suggests that the TCE contamination in well 239 has degraded at rate equivalent
to the longest reported half-life. A TCE degradation rate, equivalent to a half-life of about
4.5 years is indicated from the data from well 239. This well is at the center TCE plume
shown in the Weston RI Figure 5-4. If TCE contamination continues to degrade'at this
rate, TCE concentrations in this well will be near the MCL for TCE during the year 2009.
Guidelines for monitored natural attenuation should be implemented to confirm
degradation trends predicted in this memo .. See the comments regarding PCE at this well
described on Figure 13.
Figure 11 shows that well 285 was not contaminated in 1990. The well was contaminated
with TCE at concentrations greater than the MCL by 1995. A TCE degradation rate,
equivalent to a half-life of about 4.5 years is indicated from the data from well 285. If TCE
contamination continues to degrade at this rate, TCE concentrations in this well will be
near the MCL for TCE during the year 2006. Figure 11 shows that at this well, the clean-

estimate is similar to those obtained at other wells, the contaminants and the levels of
contamination are similar to those observed at other wells, and both the contaminant
concentrations and trends are consistent with observations from other wells, given the
location of this well in the groundwater flow system. As described in the comments
regarding Figure 10, the degradation rate should be verified by a groundwater monitoring

Figure 12 shows that well 181 was not contaminated in 1990. The well was contaminated
with TCE at concentrations greater than the MCL by 1995. A TCE degradation rate,
equivalent to a half-life of about 4.5 years is indicated from the data from well 181. If TCE
contamination continues to degrade at this rate, TCE concentrations in this well will be
near the MCL for TCE during the year 2006. As described in the comments regarding
Figure 10, the degradation rate should be verified by a groundwater monitoring program
which follows EPA guidelines regarding MNA. ·
Figure 13 shows the concentration of PCE in well 239 since 1990. Figure 13 shows that
the PCE concentration in well 239 is not degrading at a rate which can be approximated
by a first-order decay rate (the tri-angles don't fit any of the lines). The reported half-lives
for PCE are between 1 and 2 years (365 to 731 days), but PCE concentrations in this well
are not diminishing at these rates. Clean up times for PCE in this well can not be projected
by this method (See Figure 15 instead). The failure of the PCE in this well to degrade at
the expected rates may mean that a source for PCE may be present in the area. If so,
degradation of PCE in groundwater will not proceed until the source is depleted. The fact
that none of the PCE concentrations from the 1990 samples were near the Assumed Initial
Concentration of 300 µg/L shown on Figure 13, also supports the suggestion that PCE is
dissolving into groundwater at a constant rate from a small source. See the comments
regarding Figure 15.
Figure 14 shows the <eancentration of PCE in well 285 since 1990. Well 285 was not
contaminated in 1990, but groundwater from the well exceeded the MCL by 1996. There
are relatively few samples from this well, and the data on Figure 14 are insufficient to
determine which degradation rate is applicable to this well. The PCE concentrations in well
285 may be following a trend similar to well 239. As described in the comments regarding
Figure 10, the degradation rate should be verified by a groundwater monitoring program
which follows EPA guidelines regarding MNA.
PCE Summary (Figure 15)
Figure 15 shows the PCE concentration data from wells down gradient from the Davis Park
Road site (see Figure 5, 13 and 14). Based on the trend through the highest
concentrations observed in well 239, the clean up time for well 239 is projected to be
approximately 15 years (year 2015). If there is a residual source for PCE, once this source
is depleted, degradation rates should approximate rates typically observed for PCE in
groundwater, which are faster than have been observed in well 239 to date. The data for
Page 10 September 22, 2000 (1:18PM) F:IPROJECTS\DAVISPARIRPMMAIL\recomend5.wpd

• well 239 plotted on Figure 15 suggest the source is becoming weaker with time. As
described in the comments regarding Figure 10, the degradation rate should be verified
by a groundwater monitoring program which follows EPA guidelines regarding MNA. ·
PCE concentrations in wells 232 and 285 (PW1) exceed the MCL, but were less than twice
the MCL in November, 1999. Concentrations of PCE in these wells should continue to
diminish at a rate similar to that projected for well 239.
PCE was found in soils in the source area, but has never been observed in groundwater
near the source area. If PCE was ever present near the source area, ii appears to have
attenuated at rates which approximate half-lives observed at other sites and in laboratory
experiments. The PCE which remains in the aquifer down gradient from the suspected
source area is not diminishing at these rates. If the PCE in the down gradient area is from
the same source as the TCE discovered in 1990, ii has migrated into an area in which
conditions are less favorable for PCE degradation than the conditions near the source
area.
The maximum flow-path length in the area contaminated by PCE shown on Weston RI
Figure 5-3 is 1,500 to 2,000 feet. This is approximately the distance from the line of MCL
exceedance to Blackwood Creek. The contaminant travel time across this distance is
approximately 7-10 years. Regardless of the source of the PCE observed near well 239,
if the estimated contaminant migration rates are correct, much of the contamination in the
vicinity of well 239 should discharge to Blackwood Creek by the year 2005. Remaining
residual contamination should attenuate al rates similar to published half-lives, probably
by the year 2017. Groundwater between Wf:lll 239 and Blackwood Creek will be
contaminated during this period.

FinaJ Remedial Design
Section: 4
Dale: Fcbmary 2000
Prior to connection to "existing" City of Gastonia water lines, an appropriate
agreement/memorandum of understanding will be completed between EPA and the City of Gastonia.
When the construction phase is completed and all items are corrected on the "punch list", EPA will
be notified that the construction has been finalized. At this point, EPA will be responsible for the
negotiation of transfer of ownership of water lines to the City. The selected subcontractor responsible
for installation of the carbon filtration units will also be responsible for maintenance of the system.
WESTON will be responsible for replacement of the filters and sampling of the treated water for a
one year period beyond date of installation.
4.1.15 Permitting
During the design process and during the advertising of bids, WESTON will complete all permits
required by the North Carolina Department of Transportation for excavation and construction along
state maintained roads. WESTON will also examine requirements by the North Carolina Department
of Environment and Natural Resources as well as other pertinent requirements by state and local
agencies.
4.2 IMPLEMENTATION SCHEDULE
This Section presents a revised Preliminary Design schedule of the activities described in Section
4.1. The schedule is provided as Figure 4-1.

SECTION 5
BASIS OF DESIGN
• Final Remedial Design
Section: 5
Date: February 2000
The design criteria for the proposed water distribution improvements and carbon filtration units are
presented below. These design criteria conform to City of Gastonia Standard Details and
Specifications dated June 1, 1997, and general guidelines presented in Section 8 through 8. 10 of
Recommended Standards for Water Works, GLUMRB, 1992. Subsequent to receipt of the
preliminary survey and comments on the Preliminary Design document, the design criteria have been
revised accordingly. The goal of the design is to provide the homeowners a supply of drinking water
that results in minimum risk to their health.
Figure 5-1 illustrates the locations of the proposed water main and distribution lines. Figure 5-2
illustrates a typical 10 gpm carbon filtration unit installation which could serve a single household.
Standard waterline design details and manufacturer's cut sheets (revised since submittal of the
Preliminary Design document) are referenced in Section 7 -Preliminary Design Documents and
presented as exhibits in the Appendices.

This Inspection Report for the Davis Park Road Site Remedial Action in Gastonia, North
Carolina presents information collected during. oversight of the water line installation along
Davis Park Road and adjacent side streets, including Penny Park and Skyland Drives,
Springbrook Circle, and Puritan, Rotan, and Tate Streets. The water line installation was
preceded by a pre-construction meeting held at the City Hall of Gastonia, North Carolina. Actual
work on the project began on May 22, 2000 with mobilization of equipment to the site.
The following information is presented in chronological order:
Week of May 22, 2000
During this first week of field acllvlly, Trans-State Construction Company, Inc. (TSCC)
mobilized equipment to the site, conducted a utilities search, initiated excavation of pipe
trenches, and installed piping. From May 22 to May 24, 2000, equipment was mobilized to the
site including piping, fittings, valves, and other support material and was placed at the edge of
the Douglas Bell property adjacent to James May's property. This is the laydown area for the
entirety of the waterline installation phase. The materials were inspected by TSCC personnel and
WESTON's on site inspector for compliance with the standards and specifications. On May 22,

2000, the City of Gastonia Inspector was on site to determine the actual start date of construction
and to arrange for daily reviews of site activities.
Excavation for the waterline was begun, as scheduled, on May 25, 2000 with the removal of the
blow off valve at the end of the existing 12 inch water main along Davis Park Road. During this
day, the contractor installed approximately 300 linear feet of 12-inch ductile iron pipe. The
excavation along Davis Park Road continued on May 26, 2000 and was advanced another 200
feet. This portion of the pipe crossed under a gas line and, according to project specifications,
was wrapped in 8 millimeter thick polyethylene sheeting. At the end of the day, as with all
successive days, each excavation was backfilled to original grade.
Week of May 29, 2000
Excavation and installation of the waterline continued this week with TSCC utilizing two work
crews. Activity along Davis Park Road was continued and completed to the designed termination
point at the bridge over Blackwood Creek on Monday, May 29, 2000. After completion of this
portion of the pipeline, TSCC began installation of pipe along Skyland and Penny Park Drive.
By the end of the work day Tuesday, May 30, 2000, 250 linear feet of pipe and one fire hydrant
tap were installed along Penny Park Drive, a 6-inch tap had been placed at the intersection of
Tate Street and Davis Park Road as well as Skyland Drive and Davis Park Road, and 100 linear
feet of pipe was installed along Skyland Drive.
On Wednesday, May 31, 2000, TSCC crews accidentally cut a gas line along Penny Park Drive
that had not been demarcated by the local utilities locating service and actually was part of an
out-of-service line. After the gas line was severed, the local gas company was contacted for
immediate services. The line was shut off and removed from the main service lines without
incident.
By Friday , June 2, 2000, the water lines along Skyland and Penny Park Drive were complete
and connections were made at Puritan Street and Springbrook Circle. During this week,
approximately 900 feet of 8-inch pipe had been placed in the ground. Also, approval was
provided by the City of Gastonia for the thrust blocking and rodding methods used for fire
hydrant and line connection installation.
Week of June 5, 2000
The week began with a rain event on Monday, June 5, 2000. The only activities to occur during
this day were driveway pavement cuts along Puritan and Rotan Streets. Full pipeline installation
activities resumed on Tuesday, June 6, 2000, as 375 linear feet of 6-inch ductile iron pipe were
installed along Puritan Street with two fire hydrants. For the remainder of the week, TSCC
completed the line along Puritan Street with installation of an additional 280 feet of 6-inch pipe

as well as installing 25 feet of pipe along Tate Street. On Friday, June 9, 2000, all areas that had
been disturbed were seeded and covered with straw to return the area to original or equal
conditions.
Week of June 12, 2000
TSCC continued the installation of pipe along Tate Street and completed the installation for a
total of 450 feet. Following the Tate Street completion, the contractor mobilized all effort
towards Springbrook Circle. By Friday, June 16, 2000, the entire 1,410 feet of 6-inch ductile iron
pipe had been completely installed along Springbrook, signaling completion of the installatfon of
the main water lines at the Davis Park Road Site.
Remainder of the Project
TSCC is now in the testing phase of the water line installation project. This period of testing will
also allow them time to set the meter boxes for each of the homes that are scheduled to receive
the public water service. The setting of meter boxes and connection to the main lines is expected
to begin during the week of June 26, 2000. According to the Project Manager for TSCC, the
entire line installation project should be completed by August 15, 2000, well ahead of our
projected schedule.

Dear Mr. Vorsatz:
March 8, 2000
Attached is one copy of the "Financial Responsibility/Ownership Form Sedimentation PoUution Control
Act". As you will note, this form has been partially completed by WESTON, principally within those
questions not requiring a signature. Please have the necessary person within the agency complete Part B,
Number I only, and sign the back of the form at the bottom of the page in front of Notary Public, which
will provide witness to your signature. This form can be sent separate from the Sediment and Erosion
Control Drawings to Steve Allred of the Mooresville Regional Office of_NCDENR; however, as you
know, the form should be completed as soon as possible.
In addition, a copy of the North Carolina Department of Transportation Right of Way Encroachment
Agreement has also been attached for legal review by your office. Please note that the form is from July
I, 1977 and, according to the Gaston County NCDOT representative, has not been updated since.
Thank you for your time·and consideration. If you have any additional questions or require clarification,
please do not hesitate to contact me at (770)263-5443 or via email at nelsond@mail.rfweston.com.
