2.0 SITE INFORMATION
This section provides information on the history of the site and investigations conducted prior
to the pre-RI. This section also describes the regional and site-specific characteristics of the
study area including: demography, surrounding land/water use; and environmental setting.
2.1 Site Description
The Site is located between Hudson Boulevard and Dogwood Avenue west of the city of
Gastonia within the Gastonia Extra Territorial Jurisdiction area. The Site consists of an area of
contaminated soil behind the Moore's Transmission and Auto Repair Shop (Moore's) and a
plume of contaminated groundwater that begins at the Moore's property at 2307 Davis Park
Road and extends south along the west side of Davis Park Road to Dogwood Avenue. 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 (Figure 2.1). The Site can be found on the Gastonia
South, North Carolina USGS 7.5' Quadrangle Map at latitude 35° 13' 56" N and 81 ° 13' 08"
w.
The Site, situated on approximately 20 acres, includes private businesses and residential
homes. The topography of the Moore'f property is slightly sloped to the west towards
Crowder Creek. The source of the plume of contaminated groundwater is believed to be an
area of contaminated soil located behind Moore's in the vicinity of a drain line exiting the
service bay in the facility.
2.2 Demography/Surrounding Land/Water Use
Land use in the vicinity of the Site is largely residential with some industrial facilities. During
November and December 1995, a well survey was conducted. A total of 349 properties were
located and mapped around the Davis Park Road Site (Figure 2.2). A total of 48 properties
are undeveloped or are owned by the same individual adjacent to the property with the
residence location. Eighty three (83) of the residences are supplied water through private
water wells. A majority of these wells are located east of Davis Park Road. Eighty-one (81)
of the residences in the Davis Park Road area are connected to the City of Gastonia Public
Water Supply or to a restricted use water supply line supplied by the City of Gastonia. All of·· ' . the residences connected to the City of Gastonia water supply lines are located either within
the City limits or adjacent to the City limit boundary. The remainder of residences in the Davis
Park Road area receive water via a Community Water System well or a Private Water System
well. According the data collected during the well survey there are 98 supply wells (private
and community), located throughout the Davis Park Road Site area.

Preliminary Remedial Investigation Report
Draft / September 1996
The topography of the Davis Park Road Site is relatively flat around the Site but slopes
westerly towards Crowder Creek. Elevations on the Site range from approximately 770 feet
National Geodetic Vertical Datum (NGVD) around the Site, to approximately 660 feet at
Crowder Creek.
Gaston County has a mean annual precipitation of approximately 46 inches and a mean annual
lake evaporation of approximately 40 inches. Therefore, the net annual precipitation is 6
inches. The 2-year, 24 hour rainfall in this area is approximately 3.0 inches.
2.4 Groundwater/Hydrogeology
2.4.1 Geology
The Davis Park Road Site is located within the Piedmont Physiographic Province and is
further characterized as Foliated to Massive Granitic rock unit of the King Mountain Belt. The
formation is described as a coarse grain, porphyritic, well-foliated biotite granite. Others have
described this formation to have several intrusion phases exhibiting cross-cutting relationships
and differing in texture and degree of foliation. The rocks are megacrystic to equigranular • • I gramte to quartz monzomte.
2.4.2 Aquifer Use
Most of the domestic water supplies, industrial supplies and several municipal supplies in
Gaston County are obtained from wells. The wells used in rural sections are dug type wells
that derive water from the weathered and disintegrated zone-between the soil and the
underlying unweathered rock. Drilled wells, used for higher yield for industrial and municipal
use, obtain water from either granite or schist formations. These wells have an average depth
of 180 feet for schist wells and 165 for granite wells. Average yields for these formations
range from 150 and 100 gallons per minute, respectively.
The closest domestic well to the Site is the May residence, which is located approximately 250
feet south of the Site. The closest community well is the Ced:u-Oak Development located · ·
' approximately 1/4 mile south of the Site.

2.4.3 Soils
• DRAFT
Davis Park Road Site
Preliminary Remedial Investigation Report
Draft I September 1996
There are five predominate soil types in the Davis Park Road Site area. These include Appling
sandy loam, Cecil-Urban land complex, Helena-Urban land complex, Pacolet sandy loam, and
Wedowee sandy loam.
The Appling sandy loam is a well drained soil, which is located on broad, smooth ridges
throughout the county. Areas of this soil type are irregular shaped and range from 4 to 100
acres in size. Typically, this soil has a brown sandy loam surface layer approximately 10
inches thick. The subsoil, to a depth of 48 inches, is brownish yellow sandy loam in the upper
region, a yellowish brown sandy clay loam in the middle and yellowish brown sandy clay loam
mottled with red in the lower region. The underlying material, to a depth of 60 inches, is a
multicolored saprolite that has a sandy clay loam texture. Permeability is moderate and the
shrink-swell potential is low. The hazard of erosion is moderate in bare, unprotected areas.
This soil is used mainly as cropland or pasture, the rest is used as woodland or is in urban
areas.
The Cecil-Urban land complex consist of cecil soil and urban land. Cecil soil is a well drained
soil located on broad ridges mostly in and around Gastonia. Cecil soil makes up 50 to 65
percent of this land complex. Areas of this land complex are irregular shaped and range from
10 to 400 acres in size. Typically, cebil soil has a yellowish red sandy clay loam surface that
is about 6 inches thick. The subsoil, to a depth of 58 inches, is a red clay in the top region to
a red clay loam in the lower region. The underlying material, to a depth of 80 inches, is red
saprolite that has a loam texture. Cecil soil has a moderate permeability and shrink-swell is
low.· The subsoil is very acidic. The hazard of erosion is severe in bare, unprotected areas.
The Helena-Urban land complex consists of Helena soil and urban land. Helena soil is a
moderately well drained soil located on smooth ridges, toe slopes and drainage ways located.
mostly in and around Gastonia. Helena soil makes up 50 to 65 percent of this land complex.
Areas of this land complex are irregular oblong shaped and range from 4 to 20 acres in size.
Typically, this Helena soil has a grayish brown sandy loam surface that is about 8 inches thick.
The subsoil, to a depth of 39 inches, is a light yellowish brown sandy clay loam in the upper
region a pale brown to strong brown sandy clay that has light gray mottles in the mid region
and a reddish yellow sandy clay loam with light gray mottles in the lower region. The
underlying material, to a depth of 60 inches, is a multicolored saprolite that has a sandy clay
loam texture. This Helena soil has a low permeability and shrink-swell is high. The seasonal
high water table is within a depth of 18 to 30 inches. The soil is very acidic. The hazard of
erosion is moderate in bare, unprotected areas.

The Pacolet sandy loam is a well drained soil. It is located on slopes and narrow ridges
throughout the county. Areas of this soil are irregular oblong shaped and range from 5 to 50
acres in size. Typically, Pacolet soil has a brown sandy loam surface that is about 5 inches
thick. The subsoil, to a depth of 39 inches, is a red clay loam in the upper region, a red clay
in the mid region and a red clay loam in the lower region. The underlying material, to a depth
of 60 inches, is a multicolored saprolite that has a loam texture. Pacolet soil has a moderate
permeability and shrink-swell is low. The hazard of erosion is very severe in bare,
unprotected areas.
Wedowee sandy loam is a well drained soil. It is located on side slopes and narrow ridges
throughout the county. Areas of this soil are irregular oblong shaped and range from 4 to 40
acres in size. Typically, Wedowee soil has a grayish brown sandy loam surface that is about 2
inches thick. A subsurface layer to a depth of 7 inches, is brownish yellow sandy loam. The
subsoil, to a depth of 31 inches, is a brownish yellow sandy clay loam in the upper region, a
strong brown sandy clay loam in the mid region and a strong brown sandy clay in the lower
region. The underlying material, to a depth of 62 inches, is a multicolored saprolite that has a
sandy clay loam texture. Wedowee soil has a moderate permeability and shrink-swell
potential. The soil is very acidic. The hazard of erosion is severe in bare, unprotected areas.
2.5 Surface Water/Hydrology
!
The distance to the nearest downstream surface water body, Crowder Creek, is approximately
3,500 feet. The change in elevation over this horizonal distance is approximately 110 feet,
therefore the slope of the intervening terrain is estimated to be 3.7%. Crowder Creek flows
south0 southeast into South Carolina. Approximately 15 miles downstream, Crowder Creek
flows into Lake Wylie. Crowder Creek in the Gastonia area has no recreational use except for
very limited bridge fishing several miles downstream of the Site. However, once Crowder
Creek nears Lake Wylie some recreational activities such as fishing, canoeing, and swimming
are possible. The State of North Carolina has designated Crowder Creek as being suitable for
Class C uses, which include fish and wildlife propagation, secondary recreation, and
agriculture. There are no public water supply surface water intakes within 15 miles of the
Davis Park Road Site.
2.6 Wildlife Natural Resources • ...
There are no known critical habitats of Federally-listed endangered species in the vicinity of
the Site. There are, however, several endangered and threatened species identified in the
vicinity of the Site including; the Indiana Bat, Bald Eagle, Arctic Peregrine Falcon, and
Eastern Cougar.

2.7 Site History
Davis Park Road Site
Preliminary Remedial Investigation Report
Draft / September 1996
The property and building at 2307 Davis Park Road has been owned by Carl Bell (now
deceased) of Gastonia since 1960. Carl Bell leased the property to Acme Petroleum and Fuel
Company (ACME) of Gastonia in 1966. ACME held this lease until 1981. During the lease
period, the property was subleased to various service station and transmission repair shops.
Also during this lease-hold, ACME installed service bays, a drain and drainpipe, and,
supposedly, a partially aboveground tank to hold liquids poured down the drain. There has
been some doubt cast as to the existence of the tank by subsequent leaseholders.
According to a July 1992 document from the State of North Carolina Department of Justice,
the history of subleasing by ACME of the property at 2307 Davis Park Road and of lessee
housekeeping practices are as follows:
• In 1966, ACME subleased the property to Mr. Bryson Welch of Gastonia for a period
of ten (10) years. Mr. Welch has admitted pouring crankcase oil down the drain, but
denies any solvent release. Mr. Welch has produced several workers who, during
deposition, stated that no tank was ever installed in back of the station.
• Mr. Reeves McAllister subleased the Site from 1976 to 1978. No further information
is available concerning his tenaiicy. Attempts to locate Mr. McAllister by North
Carolina Department of Environment, Health, and Natural Resources (NCDEHNR)
employees have not been successful.
• Mr. James Clark subleased the Site from 1978 to 1980, during which time he operated
a transmission shop. Mr. Clark indicated that oil was on the ground in back of the
station in 1978 when he subleased the facility.
• Mr. Roy Moore of Gastonia subleased from ACME 1980 to 1981. From 1981 to
present, Mr. Moore has leased the property directly from the estate of Carl Bell.
Although there is no direct evidence of Mr. Moore's release of chlorinated solvents, he
has been cited for kerosene spills at the Site and has admitted dumping water from a
parts cleaner on the ground.
During a March 1995 preliminary industrial survey of the Daiis Park Road TCE Site
conducted by the Cost Recovery Section of EPA, City of Gastonia records were consulted to
identify businesses operating from 2307 Davis Park Road -the site of Moore's Transmission
Shop.

Previous Investigations
In March of 1990 during routine sampling of the community well at the Cedar Oak Park
Subdivision, and again in April 1990, high levels of trichloroethylene (TCE) and
tetrachloroethylene (PCE) were detected in the groundwater. During follow-up sampling by
the Gaston County Health Department (GCH), three other private residential wells were also
found to be contaminated.
•
In July 1990, the Mooresville Regional Office of the North Carolina Department of
Environmental Management (DEM), Groundwater Section, conducted a Site inspection.
During the inspection, DEM personnel discovered the existence of petroleum underground
storage tanks (USTs) on the property.

Preliminary Remedial Investigation Report
Draft / September 1996
On February 12, 1991, the North Carolina Department of Environment, Health and Natural
Resources issued a compliance notice in accordance with 40 CPR 280 70 TempruacyJank
Closures which states," when an UST system is temporarily closed for more than 12 months,
owners and operators must permanently close the UST system if it does not meet EPA
requirements."
On February 18, 1991, the USTs at Moore's Transmission and Auto Repair Shop were
removed. At the time of removal, one tank reportedly had 5 to 7 inches of product and the
other had 3 to 4 inches of product. The product had a paint thinner-like odor. Upon removal
of the tank, soils in the vicinity of the tanks were tested for contamination. Results
showed no contamination present in the soils in this area.
The North Carolina Division of Environmental Management (DEM) performed sampling of
the private wells in the vicinity of the Site from May 1990 to August 1992. Several samples
were also collected from soils behind the Moore's operation close to a drain line which exits
the rear of the building. These soils were contaminated with PCE and TCE. It is believed
that the drain line was installed when Acme Petroleum installed service bays in the shop
portion of the service station. A holding tank was to be installed, but, when bedrock was
encountered at 2-3 feet, the tank was no.t installed.
The results of the investigation conducied by the North Carolina Superfund Section confirms
that at some time during the operation of the Site as a service station or transmission and auto
repair facility, PCE and/or TCE was released from the site through a drain line installed in the
service bay area of the building. These contaminants found on-site in the soil around the drain
pipe exiting the Moore's facility, have migrated into the groundwater. PCE, TCE and their
degradation products have been found in several private wells and a community well at levels
above the Maximum Contaminant Levels (MCLs) established by the US EPA.
During an off-site reconnaissance conducted on September 14, 1993 by the North Carolina
Superfund Section, no other sources of PCE and TCE were located in the vicinity of the Site.
Based on this information, it was determined that discharges from the drain line have
contaminated the soils and subsequently the groundwater behind the Moore's operation.
2.9 Process and Waste Disposal
In July 1990, a site inspection of the Moore's Transmission Shop was conducted by the staff
from the Mooresville Regional Office, Groundwater Section of the Department of
Environmental Management and the Gaston County Health Department. During the

inspection, Mr. Roy Moore, owner of the transmission shop, stated the type of work
performed at the facility consisted of the repair and restoration of automobile transmissions.
Waste transmission fluid and oil are stored in 55-gallon metal drums, which are staged on
asphalt in the front part of the property. The waste material is recycled and used for heating
the building in the winter. Mr. Moore knew nothing of the facility when it was a service
station.
NCDEHNR Superfund Section confirms that at some time during the operation of the Site as a
service station or transmission and auto repair facility, PCB and/or TCB was released from the
Site through a drain line installed in the service bay area of the building. These contaminants.
found on-site in the soil around the drain pipe exiting the Moore's facility have migrated into
the groundwater. PCB, TCB and their degradation products have been found in several
private wells and a community well at levels above the Maximum Contaminant Levels (MCLs)
established by the US BP A.

3.0 SAMPLING STRATEGY
This remedial investigation included the collection of soil, sediment, surface water and ground
water samples specified in the Project Operations Plan (POP), April 1996. The sampling
investigation was conducted during May, 1996. All samples collected were analyzed for
volatile organic compounds. Selected samples were also analyzed for extractable organic
compounds, pesticides, PCB's and metals.
3.1 Sample Collection
All samples were collected in accordance with Section 4 of the United States Environmental
Protection Agency, Region IV, Environmental Services Division, Environmental Compliance
BranciLSta.ndarrLOptiog Proceilures and Qnality....Assuraoce_, February 1, 1991 (3).
The quality assurance and quality control procedures describe,) in this manual insure that
representative samples are collected from the various media sampled. A copy of the manual,
in addition to the Work Plan and Field Sampling and Analysis Plan, was maintained at the
field office/command post for reference during all phases of the field sampling activities. Any
deviations in sampling procedures were recorded in the field log books.
Replicate and samples were collected fcfr 5 percent of the samples. This provided a check for
sampling techniques. In addition, watt\r trip blanks were prepared with organic free water by
the Analytical Support Branch (ASB). The trip blanks were transported to the field, handled
and stored with the samples collected from the site. This provided a check to determine if
samples may have been contaminated during handling and storage.
3.2 Sample Identification
Samples collected during the project will be designated using an eight digit alphanumeric code
in the form of: DP-XXX-YYY. The prefix "DP" (for Davis Park) will be used on all sample
designations. The "XXX" represents a three digit alphanumeric sample number corresponding
to the sample collection location. In general, the samples will be numbered as foHows:
001 -199 -Normal grab or composite sample
401 -499 -Replicate (split) sample
501 -599 -Soil co-located (variability) sample
701 -799 -QNQC samples
The last two digits of the replicate and/or the co-located samples will, in general, correspond
to the sample collection location. For example, sample DP-425-GW is a replicate of sample __
DP-025-GW, and sample DP-510-SLA is a sample co-located to sample DP-010-SLA. Co-

located samples will be collected 1 foot due north of the sample collection location. If the
sample is a composite, then aliquots will be collected 1 foot due north from each aliquot
collection location.
The "YYY" represents the next two or three letters which indicate the sample matrix as
specified below:

3.6 Soil Sampling
Davis Park Road Site
Preliminary Remedial Investigation Report
Draft I September 1996
Seven surface soil samples and nine subsurface soil samples were collected from six locations
during this investigation. Sample 5-SLD is a split of sample 5-SLA. In general, the surface
soil sampling interval was O to 6 inches BLS and the subsurface soil sampling intervals were
three feet to four feet BLS and seven to eight feet BLS.
The area around Moore's Transmission shop was divided into five grids as illustrated on
Figure 3 .4. One composite surface soil sample, each consisting of five aliquots, was collected
from each grid. One aliquot was collected from the center of each area. The four additional
sampling locations were located approximately 45 feet from the center of the area at angles of
45°, 135°, 225° and 315° from north. The VOA sample container was filled from the center
aliquot prior to mixing. Two grab subsurface soil sample were collected from the center of
each area, except at location 5 where a seven to eight feet deep sample was not collected ..
Location six is where a grab surface soil sample was collected through the floor of the
transmission shop . The samples were analyzed for volatile and extractable organic
compounds, pesticides, PCB's and metals.
Locations one and two were paved with asphalt. The asphalt was removed along with any
visibily stained soil prior to collecting the surface soil sample. !

and Figure 4.1 indicates the well locations. All the samples were analyzed for volatile
organic compounds. Samples 150-PW, 267-PW, 285-PW and 300-PW were also analyzed for
extractable organic compounds, pesticides, PCB's and metals. The analytical results are
presented in Table 4.2
Volatile Organic Compounds
Volatile organic compounds were detectecd in 18 samples from 17 potable wells.
Tetrachloroethene was detected in six wells. The concentration ranged from 0. 62AJ ug/1 to 10
ug/1. Samples 239-PW and 285-PW exceeded the MCL of 5 ug/1. Trichloroethene was
detected in 7 wells and ranged in concentration from 0.92AJ ug/1 to 32 ug/1. The MCL of 5
ug/1 was exceeded in samples 121-PW, 181-PW, 239-PW and 285-PW. Other compounds
detected below MCL's included 1,1-dichloroethane, 1,1-dichloroethene, cis-1,2-
dichloroethene, 1, 1, I-trichloroethane, chloroform, bromodichlonnethane,
dibromochloromethane methoxymethylpropane and carbon disulfide.
Extractable Organic Compounds
The presumptive evidence of four extractable organic compounds was detected in sample 150-
PW. They included l000JN ug/1 of chlorocyclohexanol, l000JN ug/1 of dichlorohexane, 20JN I ug/1 of bromocyclohexanol and 20JN ug/1 of chloromethylbenzofuran. These compounds are
most likely the result of methylene chloride extraction of a chlorinated water.
Eesticides/ PCB' s
Sample 285-PW contained 0.0073J ug/1 of gamma-chlordane and the presumptive evidence of
trans-nonachlor and alpha-chlordane at concentrations of 0.004JN ug/1 and 0.0097JN ug/1,
respectively.
· No PCB's were detected in the samples.
Metals
A variety of metals was detected in all the samples including bl!rium, copper, strontium,
vanadium, zinc, calcium, magnesium, iron, sodium and potassium.· The concentrations were
below any specified primary or secondary MCL's.

A variety of metals was detected in the soil samples at concentrations consistent with the
geology of his area. Surface soil samples 3-SLA, 4-SLA and 5-SLA (5-SLD is a duplicate of
5-SLA) contained elevated levels of lead. The concentration of lead in these samples ranged
from 450 mg/kg to 630 mg/kg. The samples that contained elevated levels of lead also
contained mercury and elevated concentrations of chromium, copper, zinc, calcium and
manganese. Sample 3-SLB contained 240 mg/kg of lead but did not contain mercury or
elevated levels of chromium, copper, zinc, calcium and manganese.
Sail Baring
While collecting subsurface soil samples at location 3 a layer of visibily contaminated soil was
encountered. To determine the extent of this visibally contaminated soil a 10 foot by 10 foot
grid pattern was established as illustrated on Figure 4.5. Boreholes were advance a each of
these locations and the depths at which the contamination started and stopped were recorded.
Figure 4.6 indicates the horizontal and verticle extent of vivible contamination.

5.0 CONTAMINANT FATE AND TRANSPORT
An evaluation of the environmental fate and transport of site-related contaminants is important
in determining the potential for exposure to the contaminants. There are several mechanisms
by which contaminants may migrate. Migration into air can occur via volatilization or dust
generation. Migration into groundwater can occur by percolation of infiltrating rainwater or
groundwater flow through waste materials or contaminated soils. Transport to streams in the
area can occur via surface water runoff and through groundwater discharge. The mechanisms
of migration for the main contaminants detected at the site are discussed below.
5.1
5.1.1
Contaminant Migration
Air Migration
Generally, volatilization from soil and/or water into air may be an important transport
mechanism for the organic chemicals with Henry's Law Constants greater than 10·5 atm-
m3 /mole and the molecular weights less than 200 g/mole. The volatile organics detected in
groundwater at the site meet these criteria, and therefore, if groundw?.,er is brought to the
surface, volatilization of these chemicals of concern could be an important release mechanism.
I Fugitive dust emissions from wind or mechanical disturbances may occur from unpaved or
unvegetated areas of the site. The environmental factors that influence wind erosion are wind
speed, moisture content, vegetative cover, and soil composition. Because the environmental
factors at this site are at times and places conducive to wind erosion, each of the chemicals
detected in surface soil is susceptible to migration via fugitive dust generation.
5.1.2 Surface Water Migration
Contaminant migration into surface waters at the site may occur through surface water runoff
and/or through groundwater discharge. Upon reaching surface water, the contaminants may
remain in the water column, volatilize, or sorb to bottom or suspended sediments. Since no
volatile organic compounds were found in the surface water samples, no evidence exists that
surface water migration is occurring.
5.1.3 Soil Migration
Contaminants present in surface and subsurface soils may leach to th.o underlying aquifer.
Many factors influence the rate of contaminant movement through soils. These include the
physical/chemical properties of the contaminants (e.g., solubility, density, viscosity), and the_
physical/ chemical properties of the environment (e.g. rainfall percolation rate, soil
5-1
\ •
permeability, porosity, particle size distribution, organic carbon content). Because all these
factors can affect the rate of contaminant movement through soils, it is very difficult to predict
such movement. However, based on the dated collected in this RI, generalizations can be
made.
Sorption of the chemical to soil particles is the only significant hindrance of contaminant
migration in soils at this site. If it were not for sorption, rainfall recharge and soil
permeability are high enough such that all the contaminants would readily move through the
soils. This is evident by the movement of the volatile organic chemicals in the soils. Sorption
of these contaminants is small at this site and thus contaminants have been obseived over
significant areas in groundwater.
5.1.4 Ground Water Migration
Once the contaminants of concern reach groundwater, they will generally move as the
groundwater moves, through the process of advection. However, the process of dispersion
will also cause the contaminants to spread both horizontally and vertically, and the process of
sorption as described above will retard the movement of the contaminants. Biodegradation is
also occurring, as evidenced by the presence of trichloroethene and 1,2-dichloroethene.

Preliminary Remedial Investigation Report
Draft/ September 1996
6.0 SUMMARY AND RECOMMENDATIONS
In May 1996, EPA initiated this preliminary Remedial Investigation to address the potential
source areas and the groundwater contamination at the Davis Park Road Site. The primary
objective of the RI was to assess the nature and distribution of contaminants at the site.
EPA sampled ground water, surface water, sediment, and soil to meet the RI objectives. The
details of each of these studies are presented in Sections 3 and 4 of this report and should be
consulted for a full understanding of the results of the RI. The major conclusions reached and
recommendations are provided below.
6.1 Potable Well Sampling
Thirty samples were collected from 29 potable wells during this investigation.
Volatile organic compounds were detected in 17 potable wells. Tetrachloroethene was
detected in six wells. The concentration ranged from 0.62AJ ug/1 to IO ug/1. Two samples
exceeded the MCL of 5 ug/1. Trichloroethene was detected in 7 wells and ranged in
concentration from 0.92AJ tig/1 to 32 ug/1. The MCL of 5 ug/1 was exceeded in four samples.
Other compounds detected below MCL's included 1,1-dichloroethane, 1,1-dichloroethene, cis-,.
1,2-dichloroethene, 1, 1, 1-trichloroethane, chloroform, bromodichloromethane,
dibromochloromethane methoxymethylpropane and carbon disulfide.
The presumptive evidence of four extractable organic compounds was detected in sample 150-
PW. They included IO00JN ug/1 of chlorocyclohexanol, IO00JN ug/1 of dichlorohexane, 20JN
ug/1 of bromocyclohexanol and 20JN ug/1 of chloromethylbenzofuran. These compounds are
most likely the result of methylene chloride extraction of a chlorinated water.
Sample 285-PW contained 0.0073J ug/1 of gamma-chlordane and the presumptive evidence of
trans-nonachlor and alpha-chlordane.
A variety of metals was detected in all the samples including barium, copper, strontium,
vanadium, zinc, calcium, magnesium, iron, sodium and potassium. The concentrations were
below any specified primary or secondary MCL's. •
'
6.2 Ground Water
Two permanent monitor wells located on the Moore Transmission property were sampled. No
volatile organic compounds were detected in either well. Well 1-MW contained the
presumptive evidence of petroleum product.

No pesticides or PCB's were detected in either well. A variety of metals was detected in the
samples.
6.3 Surface Water and Sediment
Smface water sediment samples were collected from six locations during this investigation.
No volatile organic compounds were detected in the surface water samples. Sediment sample
2-SD contained 200JN ug/1 of trimethylbenzene (2 isomers) and the presumptive evidence of
petroleum product.
6.4 Soil
Seven surface soil samples and nine subsurface soil samples were collected from six locations
during this investigation.
Two samples contained volatile organic compounds including toluene, trimethylbenzeze, ethyl
benzene , m-and/or p-xylene, o-xylene, ethylmethyl benzene and trimethyl benzene. Three
samples contained the presumptive evidence of petroleum product. Extractable organic
compounds were detected in three samples. Five samples contained the presumptive evidence
of petroleum product.
Two samples contained pesticides and two samples contained PCB's.
A variety of metals was detected in the soil samples. Three surface soil samples contained
elevated levels of lead, chromium, copper, zinc, calcium and manganese. These samples also
contained low levels of mercury.
A area of visibly contaminated subsurface soil was encountered behind the Moore
Transmission building. It covered an area of approximately 700 square feet. The maximum
depth is unknown.
6.5 Recommendations
The following are recommendations for future sampling at the.site to further define the extent·'
of contamination: -..
• Additional soil samples should be collected around the Moore Transmission building to
identify a possible source area for the tetrachloroethylene contamination.

Enclosed for your review is a draft Preliminary Remedial
Investigation (RI) work plan for the Davis Park Road Site. EPA
has slated this NFL caliber site for an in-house (Fund lead)
RI/FS, with limited contractor support. The HRS document
package, currently under review by EPA, is expected to be
proposed for inclusion on the NFL.
As you may be aware, the Davis Park Road site consist of a
20 acre groundwater plume impacting private and community wells.
EPA intends to conduct a two-phased investigation approach. A
preliminary field investigation will be conducted initially,
followed by a second phase RI to fill data gaps and obtain
additionally information as required to define the nature and
extent of contamination at the Site. Plans for the preliminary
RI are discussed in the enclosed work plan.
Tentative plans are to hold a public kick off meeting the
week of April 8 with commencement of field activities in early
May. Please review the enclosed work plan and submit any
comments to me no later than Tuesday, April 2. If this deadline
cannot be met, please give me call.
I look forward to working with you and your staff on this
project and anticipate hearing from you soon.
Sincerely,
'--t----}'-ltcly L. Crane

1.0 INTRODUCTION
Davis Park Rd Sile
PRI Work Plan
March 1996
Page 1
The Davis Park Road Site (hereinafter referred to as 'the Site') consists of an area of contaminated soil behind the Moore's Transmission and Auto Repair Shop (Moore's) and a plume of contaminated groundwater that begins at the Moore's property at 2307 Davis Park Road and extends south along the west side of Davis Park Road to Dogwood Avenue. The Site also includes the Cedar Oak Park Subdivision located on the east side of Davis Park Drive within the confines of Cedar Oak Circle. The Site is situated on approximately 20 acres, includes private businesses and residential homes.
The purpose of the Preliminary Remedial Investigation (PRI), is to gather information that will help plan a more effective Remedial Investigation (RI). As part of this PRI, soil, sediments, and surface water samples will be collected.
Groundwater samples will also be collected from the existing monitoring and private wells in the area. The locations and analyses to be conducted on these samples are described in detail in Section 4 of this work plan.
The results of this investigation will be evaluated and data gaps will be determined. A formal remedial investigation (RI) will be conducted in order to cover these gaps. The RI investigation will be described in the RI work plan which will be prepared as an addendum to this work plan. After all data is collected and evaluated a RI report will be prepared.
2.0 SITE BACKGROUND AND PHYSICAL SETTING
2.1 Site Description
2. 1. 1 Location
The Site is located between Hudson Boulevard and Dogwood Avenue · west of the city of Gastonia within the Gastonia Extra Territorial Jurisdiction area. The Site consists of an area of contaminated soil behind the Moore's Transmission and Auto Repair Shop (Moore's) and a plume of contaminated
groundwater that begins at the Moore's property at 2307 Davis Park Road and extends south along the west side of Davis Park Road to Dogwood Avenue. 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 (Figure 2.1). The Site can be found on the Gastonia South, North Carolina USGS 7.5'
Quadrangle Map at latitude 35° 13' 56' N and 81° 13' 08' W.

The Site, situated on approximately 20 acres, includes private businesses
and residential homes. The topography of the Moore's property is slightly
sloped to the west towards Crowder Creek. The source of the plume of
contaminated groundwater is believed to be an area of contaminated soil
located behind Moore's in the vicinity of a drain line exiting the service bay in
the facility.
2. 1.3 Demography /Surrounding Land/Water Use
Land use in the vicinity of the Site is largely residential with some industrial
facilities. During November and December 1'995, a well survey was
conducted. A total of 349 properties were located and mapped around the
Davis Park Road Site (Figure 2.2). A total of 48 properties are undeveloped or
are owned by the same individual adjacent to the property with the residence
location. Eighty three (83) of the residences are supplied water through
private water wells. A majority of these wells are located east of Davis Park
Road. Eighty-one (81) of the residences in the Davis Park Road area are
connected to the City of Gastonia Public Water Supply or to a restricted use
water supply line supplied by the City of Gastonia. All of the residences
connected to the City of Gastonia water supply lines are located either within
the City limits or adjacent to the City limit boundary. The remainder of
residences in the Davis Park Road area receive water via a Community Water
System well or a Private Water System well. According the data collected
during the well survey there are 98 supply wells (private and community),
located throughout the Davis Park Road Site area.
2.2 Environmental Setting
2.2.1 Topography
The topography of the Davis Park Road Site is relatively flat around the
Site but slopes westerly towards Crowder Creek. Elevations on the Site range
from approximately 770 feet National Geodetic Vertical Datum (NGVD)
around the Site, to approximately 660 feet at Crowder Creek.
2.2.2 Climate/Meteorology
Gaston County has a mean annual precipitation of approximately 46
inches and a mean annual lake evaporation of approximately 40 inches.

Therefore, the net annual precipitation is 6 inches. The 2-year, 24 hour rainfall in this area is approximately 3.0 inches.
2.2.3 Groundwater/Hydrogeology
2.2.3. l Geology
The Davis Park Road Site is located within the Piedmont Physiographic
Province and is further characterized as Foliated to Massive Granitic rock unit of the King Mountain Belt. The formation is described as a coarse grain,
porphyritic, well-foliated biotite granite. Others have described this formation to have several intrusion phases exhibiting cross-cutting relationships and differing in texture and degree of foliation. The rocks are megacrystic to equigranular granite to quartz monzonite.
2.2.3.2 Aquifer Use .
Most of the domestic water supplies, industrial supplies and several
municipal supplies in Gaston County are obtained from wells. The wells used in rural sections are dug type wells that derive water from the weathered and disintegrated zone between the soil and the underlying unweathered rock.
Drilled wells, used for higher yield for industrial and municipal use, obtain water from either granite or schist formations. These wells have an average depth of 180 feet for schist wells and 165 for granite wells. Average yields for these formations range from 150 and 100 gallons per minute, respectively. The closest domestic well to the Site is the May residence, which is located
approximately 250 feet south of the Site. The closest community well is the Cedar Oak Development located approximately l / 4 mile south of the Site.
2.2.3.3 Soils
There are five predominate soil types in the Davis Park Road Site area.
These include Appling sandy loam, Cecil-Urban land complex, Helena-Urban land complex, Pacolet sandy loam, and Wedowee sandy loam.
The Appling sandy loam is a well drained soil, which is located on broad, smooth ridges throughout the county. Areas of this soil type are irregular shaped and range from 4 to 100 acres in size. Typically, this soil has a brown sandy loam surface layer approximately 10 inches thick. The subsoil, to a depth of 48 inches, is brownish yellow sandy loam in the upper region, a yellowish brown sandy clay loam in the middle and yellowish brown sandy clay loam mottled with red in the lower region. The underlying material, to a depth-

of 60 inches, is a multicolored saprolite that has a sandy clay loam texture.
Permeability is moderate and the shrink-swell potential is low. The hazard of
erosion is moderate in bare, unprotected areas. This soil is used mainly as
cropland or pasture, the rest is used as woodland or is in urban areas.
The Cecil-Urban land complex consist of cecil soil and urban land. Cecil
soil is a well drained soil located on broad ridges mostly in and around
Gastonia. Cecil soil makes up 50 to 65 percent of this land complex. Areas of
this land complex are irregular shaped and range from 10 to 400 acres in size.
Typically, Cecil soil has a yellowish red sandy clay loam surface that is about 6
inches thick. The subsoil, to a depth of 58 inches, is a red clay in the top
region to a red clay loam in the lower region. The underlying material, to a
depth of 80 inches, is red saprolite that has a loam texture. Cecil soil has a
moderate permeability and shrink-swell is low. The subsoil is very acidic. The
hazard of erosion is severe in bare, unprotected areas.
The Helena-Urban land complex consists of Helena soil and urban land.
Helena soil is a moderately well drained soil located on smooth ridges, toe
slopes and drainageways located mostly in and around Gastonia. Helena soil
makes up 50 to 65 percent of this land complex. Areas of this land complex
are irregular oblong shaped and range from 4 to 20 acres in size. Typically, this
Helena soil has a grayish brown sandy loam surface that is about 8 inches
thick. The subsoil, to a depth of 39 inches, is a light yellowish brown sandy clay
loam in the upper region a pale brown t9 strong brown sandy clay that has
light gray mottles in the mid region and a reddish yellow sandy clay loam with
light gray mottles in the lower region. The underlying material, to a depth of 60
inches, is a multicolored saprolite that has a sandy clay loam texture. This
Helena soil has a low permeability and shrink-swell is high. The seasonal high
water table is within a depth of 18 to 30 inches. The soil is very acidic. The
hazard of erosion is moderate in bare, unprotected areas.
The Pacolet sandy loam is a well drained soil. It is located on slopes and
narrow ridges throughout the county. Areas of this soil are irregular oblong
shaped and range from 5 to 50 acres in size. Typically, Pacolet soil has a
brown sandy loam surface that is about 5 inches thick. The subsoil, to a depth
of 39 inches, is a red clay loam in the upper region, a red clay in the mid
region and a red clay loam in the lower region. The underlying material, to a
depth of 60 inches, is a multicolored saprolite that has a loam texture. Pacolet
soil has a moderate permeability and shrink-swell is low. The hazard of erosion
is very severe in bare, unprotected areas.

Wedowee sandy loam is a well drained soil. It is located on side slopes
and narrow ridges throughout the county. Areas of this soil are irregular
oblong shaped and range from 4 to 40 acres in size. Typically, Wedowee soil
has a grayish brown sandy loam surface that is about 2 inches thick. A
subsurface layer to a depth of 7 inches, is brownish yellow sandy loam. The
subsoil, to a depth of 31 inches, is a brownish yellow sandy clay loam in the
upper region, a strong brown sandy clay loam in the mid region and a strong
brown sandy clay in the lower region. The underlying material, to a depth of
62 inches, is a multicolored saprolite that has a sandy clay loam texture.
Wedowee soil has a moderate permeability and shrink-swell potential. The soil
is very acidic. The hazard of erosion is severe in bare, unprotected areas.
2.2.4 Surface Water/Hydrology
The distance to the nearest downstream surface water body, Crowder
Creek, is approximately 3,500 feet. The change in elevation over this horizonal
distance is approximately 110 feet, therefore the slope of the intervening
terrain is estimated to be 3.7%. Crowder Creek flows south-southeast into South
Carolina. Approximately 15 miles downstream, Crowder Creek flows into Lake
Wylie. Crowder Creek in the Gastonia area has no recreational use except for
very limited bridge fishing several miles downstream of the Site. However,
once Crowder Creek nears Lake Wylie some recreational activities such as
fishing, canoeing, and swimming are possible. The State of North Carolina has
designated Crowder Creek as being suitable for Class C uses, which include
fish and wildlife propagation, secondary recreation, and agriculture. There are
no public water supply surface water intakes within 15 miles of the Davis Park
Road Site.
2.2.6 Wildlife Natural Resources
There are no known critical habitats of Federally-listed eridangered
species in the vicinity of the Site. There are, however, several endangered and
threatened species identified in the vicinity of the Site including; the Indiana ·
Bat, Bald Eagle, Arctic Peregrine Falcon, and Eastern Cougar.
2.3 Site History
2.3. l Site Ownership
The property and building at 2307 Davis Park Road has been owned by
Carl Bell (now deceased) of Gastonia since 1960. Carl Bell leased the property
• •
Davis Park Rd Sile
PRI Work Plan
March 1996
Page 8
to Acme Petroleum and Fuel Company (ACME) of Gastonia in 1966. ACME held this lease until 1981. During the lease period, the property was subleased to various service station and transmission repair shops. Also during this lease-hold, ACME installed service bays, a drain and drainpipe, and, supposedly, a partially aboveground tank to hold liquids poured down the drain. There has been some doubt cast as to the existence of the tank by subsequent leaseholders.
According to a July 1992 document from the State of North Carolina Department of Justice, the history of subleasing by ACME of the property at 2307 Davis Park Road and of leasee housekeeping practices are as follows:
In 1966, ACME subleased the property to Mr. i:lryson Welch of Gastonia for a period of ten (10) years. Mr. Welch has admitted pouring
crankcase oil down the drain, but denies any solvent release. Mr. Welch has produced several workers who, during deposition, stated that no tank was ever installed in back of the station.
Mr. Reeves McAllister subleased the Site from 1976 to 1978. No further
information is available concerning his tenancy. Attempts to locate Mr. McAllister by North Carolina Department of Environment, Health, and Natural Resources (NCDEHNR) employees have not been successful.
Mr. James Clark subleased the Site from 1978 to 1980, during which time
he operated a transmission shop. Mr. Clark indicated that oil was on the ground in back of the station in 1978 when he subleased the facility.
Mr. Roy Moore of Gastonia subleased from ACME 1980 to 1981. From
1981 to present, Mr. Moore has leased the property directly from the estate ofCarl Bell. Although there is no direct evidence of Mr. Moore's
release of chlorinated solvents, he has been cited for kerosene spills at the Site and has admitted dumping water from a parts cleaner on the ground.
During a March 1995 preliminary industrial survey of the Davis Park Road TCE Site conducted by the Cost Recovery Section of EPA, City of Gastonia
records were consulted to identify businesses operating from 2307 Davis Park Road -the site of Moore's Transmission Shop. Accordingly, the following dates of operation and names of businesses were found:
1956 to 1957 No business located on this property.

2.3.2 Previous Investigations
In March of 1990 during routine sampling of the community well at the
Cedar Oak Park Subdivision, and again in April 1990, high levels of
trichloroethylene (TCE) and tetrachloroethylene (PCE) were detected in the
groundwater. During follow-up sampling by the Gaston County Health
Department (GCH), three other private residential wells were also found to be
contaminated.
In July 1990, the Mooresville Regional Office of the North Carolina
Department of Environmental Management (DEM), Groundwater Section,
conducted a Site inspection. During the inspection, DEM personnel discovered
the existence of petroleum underground storage tanks (USTs) on the property.
On February 12, 1991, the North Carolina Department of Environment,
Health and Natural Resources issued a compliance notice in accordance with
40 CFR 280.70 Temporary Tank Closures which states; when an UST system is
temporarily closed for more than 12 months, owners and operators must
permanently close the UST system if it does not meet EPA requirements.'
•
Davis Park Rd Site
PRI Work Plan
March 1996
Page IO
On February 18, 1991, the USTs at Moore's Transmission and Auto Repair Shop were removed. At the time of removal, one tank reportedly had 5 to 7 inches of product and the other had 3 to 4 inches of product. The product had a paint thinner-like odor. Upon removal of the tank, soils in the vicinity of the tanks were tested for contamination. Results showed no contamination
present in the soils in this area.
The North-Carolina Division of Environmental Management (DEM)
performed sampling of the private wells in the vicinity of the Site from May 1990 to August 1992. Several samples were also collected from soils behind
the Moore's operation close to a drain line which exits the rear of the building. These soils were contaminated with PCE and TCE. It is believed that the drain line was installed when Acme Petroleum installed service bays in the shop portion of the serv:ce station. A holding tank was to be installed, but, when
bedrock was encountered at 2-3 feet, the tank was not installed.
The results of the investigation conducted by the North Carolina
Superfund Section confirms that at some time during the operation of the Site as a service station or transmission and auto repair facility, PCE and/or TCE was released from the site through a drain line installed in the service bay area of the building. These contaminants found on-site in the soil around the drain pipe exiting the Moore's facility, have migrated into the groundwater. PCE, TCE and their degradation products have been found in several private wells and a community well at levels above the Maximum Contaminant Levels
(MCLs) established by the US EPA.
During an off-site reconnaissance conducted on September 14, 1993 by the North Carolina Superfund Section, no other sources of PCE and TCE were located in the vicinity of the Site. Based on this information, it was determined
that discharges from the drain line have contaminated the soils and
subsequently the groundwater behind the Moore's operation.
2.3.3 Process and Waste Disposal
In July 1990, a site inspection of the Moore's Transmission Shop was
conducted by the staff from the Mooresville Regional Office, Groundwater
Section of the Department of Environmental Management and the Gaston County Health Department. During the inspection, Mr. Roy Moore, owner of the transmission shop, stated the type of work performed at the facility consisted of the repair and restoration of automobile transmissions. Waste transmission fluid and oil are stored in 55-gallon metal drums, which are staged on asphalt in the front part of the property. The waste material is recycled and

used for heating the building in the winter. Mr. Moore knew nothing of the
facility when it was a service station.
NCDEHNR Superfund Section confirms that at some time during the
operation of the Site as a service station or transmission and auto repair facility,
PCE and/or TCE was released from the Site through a drain line installed in the
service bay area of the building. These contaminants found on-site in the soil
around the drain pipe exiting the Moore's facility have migrated into the
groundwater. PCE, TCE and their degradation products have been found in
several private wells and a community well at levels above the Maximum
Contaminant Levels (MCLs) established by the US EPA.
3.0 EVALUATION
Based on information collected during previous investigations a
conceptual site model was developed, potential ARARs, potential remedial
technologies, and appropriate response actions, were identified for the Site.
The results of these activities are described below.
3. 1 Conceptual Site Model
The purpose of the conceptual site model is to assist in the identification
of additional sampling and/or data collection needs, and to also assist in the
identification of potential remedial technologies. Information on the waste
sources, pathways, and receptors at the Site are used to develop a
conceptual understanding of the Site to evaluate potential risks to human
health and the environment. The conceptual site model includes known and
suspected source(s) of contamination, types of contaminants and affected
media, known and potential routes of migration, and known or potential
human and environmental receptors.
The conceptual site model developed for the Davis Park Road Site is
depicted in Figures 3-1 and 3-2. Figure 3-1 provides a schematic cross-section
of the Site showing the observed and potential pollutant migration routes and
the associated exposure mechanisms. Figure 3-2 presents a detailed flow
diagram of the known or potential transport pathways and receptors. As
depicted in Figures 3-1 and 3-2, the primary transport pathways associated
with the Site include the following:

Horizontal contaminant migration in the shallow aquifer to downgradient
receptors which include private and/or community drinking water wells, surface water, springs and wetlands.
Migration of contaminants from surface soil via volatilization and dust generation.
Site conditions and the transport pathways for this Site provide numerous potential exposure pathways for human and environmental receptors including:
Ingestion of contaminated groundwater, surface water, surface soils and sediments;
Inhalation of dust released from contaminated surface soils;
Inhalation of volatile organic compounds evolved from contaminated
groundwater and surface soils; and
Direct contact with contaminated groundwater, surface water, surface soils and sediments.
The primary and secondary receptors for these potential exposures are further identified in Figure 3-2.
3.2 Chemical of Potential Concern
Based on the results of previous sampling investigations at the Site, the primary chemicals of potential concern (COPCS) for the Site appear to be Tetrachloroethene (PCE) and Trichloroethene (TCE). Selection of primary
COPCs was based on comparison of the maximum detected concentrations
of contaminants to EPA's Maximum Contaminant Levels (MCLs), State of North Carolina regulatory levels and risk-based concentrations for soil published by
EPA Region Ill (EPA 1993). Contaminants which exceeded one or both of these criteria were included as COPCS. Many other organic and inorganic
contaminants were identified in previous sampling investigations, but they did not satisfy the criteria used in this screening and were not therefore considered
primary COPCS at this time. However, since there is evidence that additional contaminants are present, complete TCL/TAL analyses will be performed on most of the samples collected and shipped to ESD or a CLP laboratory in this PRI. The results of these analyses will be used in the final determination of the contaminants of concern for the Site. All contaminants found in this

investigation will be evaluated in the baseline risk assessment and feasibility
study as appropriate. General physical, chemical, and toxicity characteristics
of the COPCs are presented briefly in Section 3.2. l.
3.2.1 Organics
Tetrachloroethene (PCE) -The major routes of exposure to tetrachloroethene
(perchloroethylene) are the inhalation and oral routes. The brain, liver, and
kidney have been identified as target organs for adverse effects of PCE
exposure. In addition, there is a suggestion that reproductive effects may also
be induced in women. Humans exposed acutely to high concentrations of
PCE had headache, dizziness, and drowsiness; nonspecific hepatoxicity;
reversible kidney damage; and upper respiratory tract irritation.
The carcinogenicity of PCE has been documented in animals exposed
by inhalation or oral routes. Despite some indication of human risk of leukemia
from solvent exposure, the relevance to human health of elevated incidences
of cancer in laboratory animals is unclear. As of November 1992, EPA had not
taken a final position on the weight-of-evidence classification for PCE. It is
proposed for consideration as a Group 82 (probable human carcinogen)
based on evidence of cancer in animals and equivocal evidence in humans.
Trichloroethene (!CE) -The central nervous system (CNS) is the principal target
for trichloroethene toxicity in humans. Human experimental studies revealed
mild effects on motor coordination, visual perception, and cognition.
Nonspecific neurological effects from TCE exposure in the workplace are
dizziness and drowsiness. Acute and chronic inhalation exposure, as well as
chronic oral exposure have lead to dysfunction of cranial nerves V and VII.
The available evidence suggests that humans may be at risk for neurological
effects from exposure to TCE in the air and water, however, there is no
information for the levels at which these effects might occur.
Workers who have been exposed to TCE in the workplace show no
higher incidences of cancer than controls. This has been shown in numerous
historical prospective studies. The few studies that did show some association
were complicated by exposures to known human carcinogens.
Animal studies have shown increases in cancers of various types
following inhalation or oral exposure to TCE. Due to various flaws in the study
designs, the significance of these studies for humans cannot be determined.
The EPA withdrew the IRIS carcinogenicity file for TCE in July 1989 and as of

November 1992 has not adopted a current position on the weight-of-evidence
classification.
3.2.2 Summary
The major chemicals of potential concern for the Site are fairly well-
defined from the environmental data collected in previous sampling
investigations. voes are presently the major contaminants of concern in soil
and groundwater
However, because the previous investigations did not fully define the
nature and extent of the contamination, further site characterization is r,9quired
to identify and assess the health and environmental concerns related i·o the
action exposure routes substantiated through the previous investigations.
These exposure routes include primarily direct contact and ingestion of
contaminated soils, sediments, surface waters, and groundwater. Inhalation of
volatile compounds from groundwater and dust from surface soil may also
serve as an exposure route.
Potential receptors include terrestrial and/or aquatic biota, local
residents and workers, recreational users of surface waters in the area, and
people who consume fish, wildlife, and agricultural products exposed to site
contaminants.
3.3 Preliminary Identification of ARARs/Other Guidelines
CERCLA compliance policy requires that any Superfund remedial action
comply with all Federal standards, requirements, criteria or limitations that are
determined to be legally applicable or relevant and appropriate requirements
(ARARs). Also, state ARARs must be met should they be more stringent.
Preliminary identification of potential ARARs and other guidelines helps to
initially identify remedial alternatives and thus allows better planning of field
data collection activities. Due to the iterative nature of the RI/FS process,
ARAR identification proceeds throughout the entire RI/FS as the conceptual
site model and remedial action alternatives are refined. ARARs may be
categorized as follows:
Chemical-specific requirements that define acceptable exposure levels
and therefore can be used in establishing preliminary remediation goals
Location-specific requirements that set restrictions on activities within
specific locations such as floodplains or wetlands.
•
Davis Park Rd Site
PRI Work Plan
March 1996
Page 17
Action-specific controls or restrictions for particular treatment and
disposal activities related to the management of hazardous wastes.
As part of development of this work plan, federal and state ARARs were·
identified in relation to the results of previous sampling investigations at the Site.
These ARARs are provided in Tables 3-2, 3-3, 3-4, and 3-5 which include state
and federal ARARs classified respectively as chemical-specific, location-
specific, and action-specific for soil/sediment and water. These ARAR lists will
be updated as appropriate to new criteria, site characteristics, and response
activities as the RI/FS proceeds.
3.4 Preliminary Remedial Action Alternatives Development
Preliminary remedial action objectives and general response actions
have been developed to assist in the identification of remedial technologies
potentially appropriate for Site remediation. The purpose of identifying
potential remedial technologies at this stage is to help ensure that the data
needed to evaluate them are collected as early as possible. In addition, the
early identification of technologies will allow early analysis as to the need for
readability studies. This i_dentification is not meant to be a detailed
investigation of alternatives. Rather it is intended to be a more general
classification of potential remedial actions based upon the initially identified
routes of exposure and associated receptors. Technologies that may be
appropriate for treating or disposing of wastes are identified. In addition, to
the extent practicable, a preliminary list of broadly defined alternatives are
developed that reflects the goal of presenting a range of distinct, viable
options to the decision-maker for remedial action at the Site (EPA, .1988). Note,
however, that the remedial technologies and alternatives identified in this
section may not be all inclusive. As additional information is gathered during
the RI, this list may be modified or expanded upon.
Tables 3-6 and 3-7 presents the preliminary remedial action objectives,
general response actions, technology types, and process options which are
applicable to the Site for soil/sediment and water, respectively. Preliminary
· remedial action objectives are based on protecting human health and the
environment. General response actions stem from the remedial action
objectives. Technologies are based on the response actions and comprise the
preliminary remedial action alternatives. The alternatives developed at this
stage will be refined throughout the RI/FS process.

4.0 REMEDIAL INVESTIGATION SAMPLING/DATA QUALITY OBJECTIVES
4. l Introduction
Davis Park Rd Site
PRI Work Plan
March 1996
Page 25
During November 1995, Dan Thoman, Kay Crane and Luis Flores
discussed the investigation sampling objectives as well as the data quality
objectives for the Davis Park Road Site project. It was determined that the
investigation will be conducted in phases. The first phase, or preliminary
remedial investigation (PRI), will be conducted in order to obtain preliminary
data which will help planning the formal RI (second phase). At this point only
two phases are anticipated.
4.2 Sampling Objectives/Data Needs
Presently there is insufficient data available to develop a risk assessment
for the soil, ground water, sediment and surface water around the Site.
Therefore, additional tasks need to be implemented to insure adequate data is
made available to develop a baseline risk assessment and a sound
remediation plan. The primary purpose of the PRI and RI is to obtain the
additional data needed to support the Baseline Risk Assessment. Specifically,
the two phased field investigation will:
Determine the nature of, and the areal and vertical extent of
contamination (waste types, concentrations, and distributions) in
soils, sediments, surface water and ground water at the Site.
Identify the source(s) of contamination.
Conduct a well survey and inventory all wells within 1/4 mile of the
Site.
4.3 Analytical and Sampling Options
Soil, sediment, surface water and ground water samples will be
collected. Table 4.1 presents the data quality objectives for each media
sampled.
All samples will be analyzed in accordance with analytical support level
l or level 4. A description of the analytical support levels are provided in Table
4.2 and were obtained from the Data Quality Objectives for Remedial

Quality assurance (QA) procedures must begin in the planning stage and continue through sample collection, analyses, reporting and final review.
The methods that will be used to insure data quality are discussed below.
6.1 Organization and Responsibilities
The Field Project Coordinator has overall responsibility for field QA. Steve Hall has been appointed QA coordinator and has the day to day responsibility to insure that prescribed routine quality control (QC) procedures are applied
and documented in the field.
All laboratory analyses will be conducted by ESD or under the CLP with
overall responsibility for laboratory QA resting with the Branch Cnief. The Organic Chemistry Section Chief and the Laboratory Evaluatio11 and Quality Assurance Section Chief, have the responsibility to insure that prescribed
routine QC procedures are applied and documented by ESD or the CLP laboratory.
6.2 Sample Collection
All samples will be collected in accordance with Section 4 of the United States Environmental Protection Agency, Region IV, Environmental Services Division, Environmental Compliance Branch Standard Operating Procedures and Quality Assurance Manual, February l, 1991 . The quality assurance and
quality control procedures described in this manual will insure that repre-
sentative samples are collected from the various media sampled. A copy of the manual, in addition to the Work Plan and Field Sampling and Analysis Plan, will be maintained at the field office/command post for reference during all phases of the field sampling activities. If any deviations in sampling procedures are used, these deviations will be recorded in the field log books.
Duplicate samples will be collected weekly for 5 percent of the samples
collected for each matrix. This will provide a check for sampling techniques.
In addition, when water samples are collected, water trip blanks will be prepared with organic free water by the ASB. The trip blanks will be transported to the field, handled and stored with the samples collected from
the Site. This will provide a check to determine if samples may have been contaminated during handling and storage. Equipment rinse blanks will be collected, if required, from equipment cleaned on Site, using organic free
water, at least weekly or more frequently at the request of the field quality control coordinator. The equipment rinse blanks will be collected to ensure that the sampling equipment is properly field cleaned.

The PRI soil, groundwater, sediment and surface water sampling will be
conducted during May 1996. The RI will be conducted after the results of the
PRI are evaluated. An addendum to this plan describing the RI field activities
will be submitted at a later time.
7.0 FIELD SAMPLING AND ANALYSIS PLAN
This Davis Park Road Site investigation will be conducted in two phases.
Phase one (PRI) includes the collection of samples from some potable water
wells located within 0.25 miles of the Site, ground water samples from existing
monitor wells, soil, sediment, and surface water samples. Based on the results
of phase one sampling, additional potable well and soil samples may be
collected. Also, temporary and/or permanent monitor wells may be installed.
The estimated number of samples for phase one is shown in Table 7-1.
However, field personnel will be responsible for the final selection of the
sampling locations which may have a slight impact on the type and number
of samples collected. All the soil, sediment and surface water samples
collected will be analyzed for volatile and extractable organic compounds,
pesticides and PCB's. All the ground water samples will be analyzed for
volatile organic compounds. Approximately 10% of the ground water samples
will also be analyzed for extractable organic compounds, pesticides, PCBs,
and metals.
7.1 Sample Identification
Samples collected during the project will be designated using an eight
digit alphanumeric code in the form of: DP-XXX-YYY. The prefix 'DP' (for Davis
Park) will be used on all sample designations. The 'XXX' represents a three digit
alphanumeric sample number corresponding to the sample collection
location. The sample collection locations are specified on the Figures
presented in sections 7.1 through 7.4. In general, the samples will be
numbered as follows:
001 -199 -Normal grab or composite sample
401 -499 -Replicate (split) sample
501 -599 -Soil co-located (variability) sample
701 -799 -QA/QC samples
The last two digits of the replicate and/or the co-located samples will, in
general, correspond to the sample collection location. For example, sample -

project numbers will be assigned at a later time. The account numbers that will
be used by the field personnel through out the field sampling portion of the
investigation will be 6TFA04PNC000.
7.2 Soil Sampling
The Site will be divided into five grids as illustrated on Figure 7.1. One five
aliquot composite surface soil sample will be collected from each grid. The
surface soil sample interval will be 0 to 6 inches BLS. One aliquot will be
collected from the center of each area. The four additional sampling
locations will be located approximately 45 feet from the center of the area at
angles of 45°, 135°, 225° and 315° from north. The VOA sample container will
be filled from the center aliquot prior to mixing. A grab subsurface soil sample
will be collected from the center of each area at a depth of three feet to four
feet BLS. Also, grab subsurface soil samples will be collected from locations 3
and 4 at a depth of six feet to eight feet BLS. The samples will be analyzed for
volatile and extractable organic compounds, pesticides and PCB's.

8.0 FIELD HEALTH AND SAFETY PLAN
8.1 Purpose
•
Davis Park Rd Site
PRI Work Plan
March 1996
Page 42
The purpose of this safety plan is to assign responsibilities, establish
personnel protection standards, establish mandatory safety operating
procedures, and provide for contingencies that may arise while conducting
this remedial investigation. All aspects of the field operations must comply with
the US-EPA, Region IV, Field Health and Safety (6) manual (which is consistent
with US-EPA Orders 1440.2 and 1440.3)and Occupation Safety and Health
Administration regulations (29 CFR 1910.120).
8.2 Application
The provisions of this safety plan are mandatory for all EPA personnel and
personnel under contract to EPA involved with this investigation. Application of
this safety plan include the sampling and mitigation undertaken on the Site or
at any off-site areas which may be affected by contamination from the Site.
All visitors (state, contract, EPA personnel, etc.) will be required to abide by
these safety procedures. Refusal to comply with the safety guidelines
established will result in the visitors being barred from the Site or the suspension
of work.
8.3 Responsibilities
The field project coordinator (Dan Thoman) and the safety officer (Steve
Hall) will have the primary responsibilities for:
l . Assuring that appropriate personnel protection equipment is available
and properly utilized by all field operations personnel.
2. Assuring that field personnel are aware of the provisions of this plan, are
instructed in the work practices necessary to ensure safety, and in
planned procedures for dealing with emergencies.
3. Assuring that personnel are aware of the potential hazards associated
with the Site operations.
4 . Supervising the monitoring of safety performance by all personnel to
ensure that required work practices are employed.
• •
Davis Park Rd Site
PRI Work Plan
March .1996
Page 43
5. Assuring personnel have had proper safety training before participating
in the investigation and have read the Region IV, Field Health and Safety
(6) manual.
6. Correcting any work practices or conditions that may result in injury to
personnel or exposure to hazardous substances.
7. Assuring that proper emergency first aid equipment is available (eye
wash station, first aid kit, etc.)
The safety officer will have the ultimate authority on all safety decisions
and can suspend project operations if required safety procedures are not used
by field personnel. In addition, prior to the initiatio!') of work each r:,ay, a safety
meeting will be held by the safety officer with field personnel to discuss field
safety operations.
8.4 Training Requirements
All field personnel must have received a minimum of 40 hours of initial
personnel protection training off-site. Personnel must also receive
cardiopulmonary resuscitation (CPR) and first aid training prior to Site entry
(which can be included in the 40 hours of personnel protection training). All
personnel that have never worked at a hazardous waste site will be
accompanied by an experienced employee for at least 3 days prior to being
expected to work at the Site without direct safety supervision. All certifications
of training will be provided to the safety officer prior to Site entry. The safety
officer will maintain a copy of all certifications at the field office for all field
personnel.
8.5 Medical Monitoring
Prior to Site entry all field investigative personnel must under go a
baseline medical examination. The examination should include the basic
physical examination, heart status and functions (EKG), chest x-ray, pulmonary
function, blood work (full SMAC series, hemoglobin -cell count and protein
levels, acetylcholinesterase activity, heavy metals -lead, cadmium, mercury,
arsenic, chromium, and selenium), liver function -full enzyme function, renal
function (BUN, creatinine, creatine/creatinine ratio, lipoprotein count and
differential uric acid), urinalysis, audiometry -audio spectrum response of the
ear and an eye examination -physical condition, visual acuity.

8.6 Site Safety Considerations
Davis Park Rd Site
PRI Work Plan
March 1996
Page 44
Previous sampling at the Site revealed the presence of extractable and volatile organic compounds, PCB's and metals in the soil and ground water. Hand augers will be used during the remedial field investigation. It is possible that during these field operations the liberation of irritating and possibly toxic vapors might occur. However, it is felt that the likelihood of this occurring is remote. Regardless, the location of the nearest phone, the emergency phone numbers and the route to the nearest hospital will be placed in each vehicle. It is the responsibility of the safety officer to ensure that all field personnel know the route to the hospital and have a copy of the emergency phone numbers.
8.7 Site Monitoring and Routes of Exposure
During various phases of the sampling activities, the Site may be monitored with a photoionization detector, an organic vapor analyzer (OVA), a radiation survey meter and a combustible gas meter/oxygen meter. It will be the safety officer's responsibility to determine what level of monitoring, if any, will be required for each sampling event. Table 8.1 lists the action levels for each of the air monitoring instruments/meters. If readings on the
instruments/meters exceed those listed in Table 8.1, then the personnel must discontinue field operations and discuss the findings with the safety officer.
It is felt that volatile organic compounds will constitute the greatest known chemical risk to field personnel. Routes of exposure for these compounds would include inhalation, ingestion and dermal contact. The ingestion route represents minimal risks but the inhalation and dermal routes present possible risks. Therefore, the safety officer will determine what levels of
protective clothing will be worn by field personnel to eliminate these risks.
8.8 Protective Clothing
Levels of protection referred to in the subsequent sections are defined in the Region IV, Field Health and Safety (6) manual.
8.8.1 Protective Clothing/gloves
All personnel will have Level D protective clothing available to wear. The protective clothing and gloves required to be worn will be mandated by the safety officer and may differ from one sampling location to the next.

8.8.5 Respiratory Protection
The respiratory protection that will be made available to field personnel will be:
• Five minute air escape capsules (ISi ELSA)
• Air purifying respirators (MSA ultra twin)
Only NIOSH/OSHA approved equipment will be used. The safety officer will determine what level of respiratory protection will be required for the field personnel by using the air monitoring equipment. ·
8. 9 Emergency Contingency Plan
On-site emergencies could be expected to result from fire, chemical
exposure or personnel casualty. If an incident occurs necessitating a response to an emergency, the project leader or safety officer will use the two-way
radios to communicate the emergency to personnel on site and/or sound an emergency horn.
The signal will be of at least 5 short blasts (each of about l second duration). Personnel on site will immediately discontinue field operations and
assemble at a pre-specified location.
