1. INTRODUCTION
This Project Operations Plan (POP) was developed to guide the remedial in-
vestigation sampling activities to be conducted at the FCX-Statesville (FCXS) NPL
Site located in Statesville, Iredell County, North Carolina (Figure 1-1). This
POP is being prepared in accordance with the Guidance on Remedial Investigations
Under CERCLA (1). The POP includes the Field Sampling and Analysis Plan (FSAP),
the Site Management Plan (SMP), the Quality Assurance Project Plan (QAPP) and the
Health and Safety Plan (HASP) for the remedial investigation. The sampling plan
discusses procedures that will be used to assure the precision, accuracy, com-
pleteness, and representativeness of the samples collected, including the data
quality objectives.
1.1. Site Background
1.1.1. Facility and Locale
The FCXS site is located on Highway 90 approximately 1. 5 miles west of
downtown Statesville at the intersection of Phoenix Street and West Front Street
(Figure 1-2). The area is characterized by the presence of light and heavy
industry, small businesses, residential neighborhoods and a school in the
immediate vicinity. The coordinates of the site are latitude 35° 47' 11'1 north,
longitude 80° 54' 58" west. (2)
The site, shown in Figure 1-3, comprises about 5.5 acres and is bounded by
the Southern Railroad and Burlington Industries to the north, the Carnation Milk
Company to the west, a small business/residential area immediately south of West

Phoenix Street.
1.1.2. Site Ownership and Operational History
1.1.2.1 Chronological Development of the Site
Based on available file information, it appears that FCXS began operations
at the site as an agricultural supply distribution center about 1940 and
continued to operate the site until bankruptcy. Prior commercial use of the
site, if any, is not known. It appears ,that two main activities were conducted
at the site. Initial operations consisted of the formulation, re-packaging,
warehousing and distribution of farm che1nicals, primarily pesticides and
fertilizer, and the milling and sales of feed grains. This activity was
initially restricted to the eastern two-thirds of the site. Figure 1-4 shows the
approximate locations and identifications of site buildings present during this
time. The year of the photograph for which Figure 1-4 was based on was estimated
as 1950-1951, by observation of vehicles present on site. Initial operations
also consisted of cleaning and treating of seed grains, apparently with mercury-
containing compounds. (3)(4)(5)
At some time after 1950-1951, the site underwent several structural and
operational changes. The western half of the horse-shoe shaped building in the
center of the site was demolished and the upper portion of the current warehouse
was constructed, extending to near the the property line between the adjoining
Carnation Milk Company property. The small building adjoining the feed mill at
the intersection of Phoenix Street and the railroad tracks near the northeastern

corner of the site was also removed. Re-packaging of liquid pesticides ceased
in 1966. Dust re-packaging was discontinued in 1969. This was the status of
the site in 1969, based on historical aerial photography. Figure 1-5 shows the
locations and identifications of the site buildings at this time. The only known
significant operational and structural changes that occurred after this time was
the re-packaging of rat bait in the early 1980's and construction of the lower
portion of the warehouse in 1982. The current status of the site is discussed
in Sec. 1.1.3., Site Description. (4)(5)
1.1.2.2 On-Site Pesticide Burial, 1966
The most i1nportant historical activity at the site, from an environmental
standpoint was the burial, in 1966, of DDT, TDE, and possibly liquid chlordane.
Approximately 7,000 to 10,000 pounds of these compounds were buried in two (2)
adjacent trenches approximately 10-feet deep. Figure 1-6 shows the presumed
location of these trenches. The material was supposedly a mixture of powders and
liquids in a variety of packaging, including paper bags and other types of
typical consumer packaging. After burial was completed, the trenches were
covered with six feet of on-site soils and a reinforced 8-inch thick concrete
slab was poured over the·area. This was follwed by construction of the upper
portion of the current warehouse. According to a past FCX employee, there is the
possibility that the trenches were obliterated soon after burial, during
extensive construction related grading. During this time, other packages were
taken to the old Statesville landfill. (3)(4)(5)(6)

1.1.2.3 Additional On-Site Burial
During a site reconnaisance on February 12, 1991, a past employee of the
construction company responsible for much of the historical site demolition and
construction was interviewed. He indicated that he and other employees were
instructed to place various bagged and bottled pesticides in a hole located in
the current vicinity of the northeast corner of the lower portion of the
warehouse. The hole was apparently located within approximately 35 feet of the
railroad tracks. Possible locations could range from the inside corner of the
lower warehouse to a location beneath the large concrete slab east of the
building. This area is shown in Figure 1-6 and will be the subject of an
investigatory boring program during the remedial investigation. Samples will be
collected if buried material is evident. No date could be ascertained for this
activity.
1.1.3. Site Description
The Site, defined as the area south of the Southern Railroad, east of the
Carnation Milk Company property, west of Phoenix Street, and north of West Front
Street, is currently abandoned. Figure 1-3, the Site Map, shows the location and
identification of site buildings and structures, as well as prominent off-site
s,truc tu res.
The dominant on-site structure is the warehouse located on the western half
of the property. It consists of two attached structures, an upper building,
constructed in 1969 or 1970, and a smaller, lower building constructed in 1982.

(3) The area south of the warehouse, except for a narrow grass strip along the
sidewalk, is totally paved.
The eastern half of the Site is dominated by a large concrete slab, six-to
seven-inches thick, 62-feet wide and 190-feet long, extending approximately 190
feet from the eastern end of the warehouse along the north property line. The
slab was poured in two sections and appears to be in good condition. The next
level below the slab is covered almost entirely with an undetermined thickness
of crushed, compacted gravel. Several smaller areas within this area are paved
with either concrete or asphalt.
The area thus described, except for the paved area between the warehouse and
the street, is completely fenced, most with chain-link fencing. The fence is in
good condition and access is gained through a 36-foot wide gate along the eastern
end of the Site.
There are at least two underground tanks present at the Site, a 7,500 gallon
gasoline storage tank and a 10,000 gallon diesel fuel storage tank. These are
apparently located in the vicinity of the fuel pumps near the area where the
upper and lower warehouses join. (5)
Eight ground water monitoring wells, shown on Figure 1-3, are also present
at the site. Four were installed in 1976 as part of a pre-purchase environmental
evaluation conducted for Southern States Cooperative (3). Four were installed
in 1989 in conjunction with the emergency action conducted by US-EPA. (6)(7)

A small, vacant two-story brick building is located at the southeastern
corner of the site just beyond the eastern fence. This building served as
offices while FCX was in operation. Most of the area between the eastern fence
and Phoenix Street, except for that area occupied by the building, is covered
with grass.
1.1.4 Licensed EPA Establishment
The facility was licensed as and operated as an EPA Establishment to
manufacture or re-package pesticides including, at various times, DDT, TDE,
Lindane, Chlordane, Malathion, Aldrin, Heptachlor, and a tobacco spray, probably
MA-30. Notable spillage is reported to have occurred at the transfer areas. (5)
1.1.5. NPL Listing
The FCXS site was evaluated using to the EPA Hazard Ranking System and
proposed for inclusion on the National Priority List (NPL) on June 24, 1988. The
site scored 37.93, based solely on the ground water pathway. The site was placed
on the NPL on February 21, 1990. (8)
1.2. Environmental Setting
1.2.1. Landforms
The FCXS site is located in Iredell County, in the Upper Piedmont Plateau of
North Carolina. The topography of the area can be generally characterized as
gently rolling and sloping, with on-site slopes ranging up to 1.5 percent.

Slopes in the immediate area range from 2 to 6 percent, however. Elevations
within a four-mile radius of the site range from 740 to 970 feet above mean sea
level. (9) (10)
1.2.2. Surface Waters
Surface waters identified within a five mile radius of the Site include both
Third Creek and Fourth Creek, as well as their tributaries. The closest of the
creeks is Third Creek, which is approximately 1.5 miles southeast of the site
(two (2) miles stream distance). As can be seen in Figure 1-7, all surface water
within this area discharges into the South Yadkin River approximately 15 miles
to the east. This river is a major drainage feature for the Piedmont region east
and south of the Site. (5)
1.2.3. Geology and Soils
The FCXS site is located in the Piedmont Physiographic Province, within the
lithologic and structural feature referred to as the Blue Ridge-Inner Piedmont
Belt (11). Rock types within this region are primarily gneisses and schists,
which frequently grade from one type to another. These rocks are typically
f~actured to varying degrees and 1nay display a prominent gneissoid or schistose
structure. In addition to this 1neta111orphic suite of rocks, granitic intrusions
are also common in this region. Avail3ble geologic maps indicate that the FCXS
site is located very near the contact bewteen a granitic intrusion and a rock
unit characterized as a hornblende gneiss. Figure 1-8 is typical of these maps.
Hornblende gneiss typically weathers to a deep red or brown soil in this region.

Based on the deep red to brown soils observed at the site, it is presumed that
the site is underlain by the hornblende gneiss. (9)(12)
Soil and other weathered overburden, collectively referred to as residuum,
overly the gneiss. This material varies in thickness across the area, ranging
in thickness from only a few feet to over 100 feet, averaging 35-feet thick.
Boring logs for wells installed at the FCXS site indicate that residuum at the
Site is approximately 60 to 70-feet thick. (12)(13)
1.2.4. Ground Water
1.2.4.1 Hydrogeology
The Site hydrogeology is probably characteristic of the general scenario
developed for the Piedmont region of North Carolina and other geologically
similar areas. Typically, a layer of residuum, comprised of surficial soil and
saprolite overlies a fractured, unweathered bedrock. The type of bedrock, the
nature of the weathering interval and degree of fracturing varies from one area
to another. In the most general terms, the saprolite serves as a ground water
reservoir, created primarily by the accumulation of infiltrated precipitation.
This reservoir supplies ground water to the fractures, faults and other secondary
permeability features in the bedrock. Ground water systems in these areas,
therefore, are generally one, interconnected system_, with the majority of ground
water within this system usually occurring at depths less than 150 feet. The
ground water surface within the residuum is normally a subdued replica of the
surface topography, i.e., ground water flow generally occurs from higher
elevations to lower elevations. Flow is typically perpendicular to contour lines

and towards the direction of streams and rivers, where ground water discharge
occurrs. (11)(12)
Well logs for the four gr6und water monitoring wells installed for the Hart
investigation and construction diagrams for deep wells installed for the EPA
emergency action indicate that saturated saprolite at the Site is approximately
thirty-feet thick. (3)(13)
Yields for wells in the area are highly variable and depend on a number of
factors. In general, saprolite wells have lower yields than wells installed in
the fractured bedrock. Within the bedrock, yields are a function of the number
and size of fractures, faults or other permeablility features encountered by the
well bore, as well as pumping level. The average yield for drilled wells six
inches in diameter in the area is less than 19 gallons per minute, although the
I deep well located on the Carnation Milk Company property reportedly yields in
excess of 500 gallons per minute. Many home water supply wells yield less than
10 gallons per minute. (12)
1.2.4.2 Aquifer Use
Although there are several public water supplies within Iredell County,
including the Statesville public water supply, the West Iredell Water Company,
and the Iredell County Water Corporation, there are apparently no consumers
within a four-mile radius of the site which rely on a ground water-based public
1 water supply. There are numerous homes, however, representing as many as 4,500
people within the four-mile radius of the site, which have private water supply

wells. It is not known how many of these are using their private well or have
been hooked-up to one of the available public water supplies. (10)(12)
1.3. Summary of Past Investigations
There have been several sampling investigations, of varying scope, at the
FCXS Site. These investigations were conducted by the North Carolina Department
of Human Resources (DHR), US-EPA, and Fred C. Hart, for Southern States
Cooperative, one-time potential purchasers of the site. Following is a summary
of the investigations. Designations for wells sampled for these investigations
are not necessarily consistent from one investigation to another, Data may be
compared using well locations as shown in the figures, however.
1.3.1. Fred C. Hart Associates, Inc. February 1986 (3)
During February 1986, Fred C. Hart conducted a pre-purchase environmental
evaluation of the Site for Southern States Cooperative, Inc. Four ground water
samples were collected from wells installed as a part of the evaluation, and fi~e
composite soil samples were collected from locations around the site. All
samples were analyzed for priority pollutant pesticides. The ground water
samples were also analyzed for priority 'pollutant volatile organic compounds.
S~mple locations and analytical summaries for tl1ese samples are shown in Figures
1-9 and 1-10.
Soil analyses detected nine (9) pesticides, of which chlordane and 4,4-DDT
were found at the highest concentrations, 8,000 ug/1 and 2,600 ug/1,
respectively. Pesticides and volatile organic compounds were detected in the

ground water samples. Gamma-BHC was the prominent pesticide found in three of
the wells, including the upgradient well. Other isomers of BHC, as well as a
possible metabolite of endrin ketone, were also detected. Trichlorofluoromethane
and tetrachloroethylene were the volatile organic compounds detected at the
highest concentrations. Well MW-3 was the well most contaminated with
pesticides; well MW-2 was the well most contaminated with volatile organic
compounds.
The ground water data may be somewhat suspect, as the wells were installed
with little regard for quality control and quality assurance. The wells were
constructed with friction-fitted PVC, tiped together with duct tape, and the
drilling equipment was not adequately cleaned bewteen wells.
1.3.2 DHR. May 1986 (4)(5)
The DHR conducted a Site Inspection in May 1986. The on-site monitoring
wells and a deep, water supply well west of the site on Carnation Milk Company
property were sampled, as well as six soil sample locations. Figure 1-11
contains an organic compound analytical summary, with sample locations, for this
investigation.
Most of the soil sample locations were in the same areas as those sampled by
Fred C. Hart in February 1986. One sample was collected south of West Front
Street in the yard of a residence. Lindane was once again identified in a sample
from we 11 MW-3. Fluorocarbons were identified in well MW-4, the upgradient well.
and chlorinated solvents were identified in well MW-2 and the deep well on Carna-
tion property, east and west of the warehouse, respectively. Caprolactum, a

component of nylon manufacturing, was detected in all of the on-site monitoring
well samples. Although the report attributes the source of this compound in the
samples to the nylon bailer rope used for sampling the wells, the most likely
source may be historical ground water contamination originating under the
Burlington Industries facility north of the Site. During prior ownership, the
Burlington plant was engaged in nylon manufacturing and may have had spills of
nylon component compounds.
The soil sampling data revealed that, in addition to chlordane, DDT and
dieldrin were also found at several locations in the vicinity of the warehouse.
These compounds were also detected in the soil sample from the yard of the
residence across West Front Street from the warehouse.
1.3.3 EPA (Weston•SPER) Emergencv Response, January 1989 (6)
In January 1989, Weston•SPER, Atlanta, Georgia, conducted an emergency
response sampling investigation at the 'rcxs site to determine the nature of
pesticide contamination at locations previously sampled by Fred C. Hart and the
DHR and to attempt to locate the two on-site burial trenches allegedly used to
dispose of pesticides in 1969. No pesticides were detected in any of the samples
collected outside of the warehouse bui]ding. The detection limit for these
samples, however, were somewhat higher than those for the previous studies.
Further, no evidence of the alleged burial was observed in any of the
approximately 30 borings completed th Lough· the floor of the upper warehouse
building. Subsequent conversations wcth a past FCXS employee indicates that the
borings may have been located too far to the east to intercept the trenches.

1.3.4 EPA (Weston•SPER) Emergency Response. August 1989 (14)
Four (4) new ground water monitoring wells were installed at two locations
at the Site. At each location two (2) wells were installed as a shallow (45-feet
depth) and deep (125-feet depth) cluster. These wells. as well as the four (4)
Fred C. Hart wells were sampled for a variety of volatile organic compounds and
pesticides. Figure 1-12 shows the locations of these samples and the analytical
summary for the compounds detected in the samples.
The most significant contamination identified was a mixture of various pur-
geable halocarbons and was observed at the greatest concentrations in well MW-SD,
a deep well located near the northeast corner of the Site, and well MW-1, a
shallow well located in the parking lot against the south face of the warehouse.
All wells showed some indication of this type of contamination, with tetra-
chloroethylene being the compound identified at the highest concentrations in
most samples. Pesticides, all BHC isomer,s were detected in wells MW-1 and MW-3.
1.3.5 EPA (0.H. Materials) Emergency Response, January 1990 (15)
During the week of January 8. 1990, 0.H. Materials sampled all eight of the
on-site monitoring wells for the Emergency Response and Removal Branch, EPA,
Atlanta. The results of this sampling are summarized and shown on Figure 1-13.
The results indicate the presence of pesticides in all wells, except for the
cluster of wells in the northeast corner of the site. Other important
observations are the presence of trichlorofluoromethane in the well located near
the northwest corner of the Site and the presence of significant concentrations

1.3.6 NUS Screening Site Inspection, Burlington Industries,
1990 (10)
During the week of August 20, 1990, NUS Corporation conducted a screening
site inspection at the Burlington Industries facility located immediately north
of the FCXS site. During this inspection, two ground water samples were
collected from a pair of wells located near the northeast corner of the FCXS
site. These wells were constructed in 1989 during the emergency removal at the
site and are identified for this report.as SS and 5D. The locations of these
wells and a summary of the organic compou1nd analytical data for each is shown on
Figure 1-14. Well 89S is a shallow saprolite well, approximately 45 feet in
depth. Well 89D is a deep bedrock well, approximately 125 in depth. Most
notable in these samples is the presence of toluene and dichloroethene in the
deep well.

2. SAMPLING LOCATIONS AND RATIONALE
2.1. Sampling Areas
The primary area of investigation consist of the main site area, which is
comprised of the area east.of the Carnation Milk Company property, south of the
Southern Railroad, west of Phoenix Street and north of West Front Street, as well
as portions of the Carnation and Burlington properties, the lot east of Phoenix
Street, and the residences and businesses south of West Front Street. Limited
surface water and sedi~ent sarnpling will also be conducted in prominent surface
water features located off-site. The following sections describe the sampling
rationale/protocols and provide sample location maps for each of the media.
2. 1. 1. Soil
Both surface and subsurface soil samples will be collected at various
locations on and off site during the study. At locations west, south and east
of the site, shown in Figure 2-1, a total of twenty-seven (27) grab surface soil
samples and three (3) grab subsurface soil samples will be collected. The three
(3) subsurface soil samples will be collected at depths of 36"-48", 72''-84'' and
108''-120'' and, along with the surface sample from that location, will comprise
a set of control samples for the study. These samples will be collected prior
to the collection of any other soil samples for this study. These areas are
located up-grade or adjacent to past-actfve material handling areas associ~ted
with historical site activities and are not thought to have received either solid
or liquid product or material in any qua~tity or concentration that would have
resulted in either significant surficial contamination or migration into the

subsurface. Results from these sample locations, however, will be evaluated
against risk-based values for any contamiriants that might be identified, and if
warranted, subsurface samples will be collected in these areas to characterize
any potential risk posed by subsurface soils. Subsurface samples in this area
may also be collected during subsequent phases of the investigation in response
to identification of significant contamination in subsurface samples collected
from adjacent areas during the initial phase of the investigation.
The next area to be sampled is shown in Figure 2-2. Area 2 consist of all
the remaining area within the area of investigation, excluding the warehouse.
At locations within this area, a total of ninety-four (94) surface and subsurface
soil samples will be collected. The number samples collected at the various
locations identified in Figure 2-2 will vary with location of the station. At
each of the four identified piezometer locations, five (5) samples will be
collected at intervals of 0 11 -2411 , 60 11 -84", 12011 -14411 , 18011 -20411 , and 240"-264"
below ground surface. At twenty-six (26) locations in this area, two samples
will be collected, at intervals of 0 11 -6 11 and 24 11 -3611 • At five locations, three
samples will be collected, at intervals of 0 11 -6 11 , 2411 -36", and 48 11 -60". These
depths will be measured relative to the original ground surface. At two other
locations just north of the retaining wall and rip-rap bank along the sidewalk
in the southeast corner of the site, three (3) samples will also be collected.
The first sample at these two locations, however, will be a composite of the fill
material encountered during the first six feet of augering. The other two will
be collected from intervals relative to the original ground surface, if
ascertainable, at 0 11 -6 11 and 24 11 -36 11 • The sampling depths selected for ireas 1
and 2 are consistent with the apparent contaminant attenuation observed in the
results of the previous investigations described in Sec. 1.3.

The last area in which soil sampling will be conducted, designated as Area
3, is the warehouse. The proposed sample locations within both the upper and
lower warehouses are shown in Figure 2-3. A total of fifty-eight (58) samples
is anticipated for both buildings. The greatest concentration of samples will
be collected in the western portion of the upper section of the warehouse.
Sampling conducted in 1989 in the eastern portion of the upper section did not
detect any evidence of the presence of trenches beneath the floor of the
building. A review of historical photographs indicates that the trenches, if
present, may be located further to the west, relative to the area that was
sampled. As such, two (2) confirmatory borings will be located in the eastern
portion of the upper building, to verify previous sampling, and 18 (eighteen)
borings will be located in the western two-thirds of the building in an effort
to locate the trenches. Prior to sampling the locations in the western portion
of the building, a micro-gravity survey will be conducted to complement the
micro-gravity survey conducted in 1989. The microgravity survey will be
subcontracted and will be conducted according to accepted protocols for
microgravity surveys. Sample locations tn this area, therefore, are subject to
change, based on the results of this survey. If, through this combined effort,
trenches are located, some designated sampling locations in this portion of the
building may be omitted and the sampling effort will concentrate on
characterizing undisturbed soil beneath the trenches. Successful completion of
this activity will be contingent on a number of factors including success in
penetrating the material and debris in the trench, as well as the appropriateness
of the activity from a personnel protection and safety stand-point.
In the absence of trenches, attempts will be made to sample beginning at the
interface between the fill and the in-place soils. If this boundary is not

distinct and obvious to sampling personnel, the depth below the floor for this
boundary at each location will be estimated based on observations of cut-and-fill
practices used in construction of the warehouses. The estimated depth to the
interface will be marked on all station flags or markers and will represent the
beginning of the sampling interval. Samples will be collected at 0"-12" and 36"-
48'' below the estimated interface.
Six (6) composite samples of the fill material, included in the total of
fifty-eight (58) samples planned for the warehouse area, will be collected, two
(2) from the lower building and four (4) from the upper building. These will be
selected at random and will provide soil characterization data for the fill used
beneath the floors in these buildings.
2.1.2. Surface Water and Sediment
Based on site observations and topographic map indications, it appears that
there are two surface water/sediment pathways potentially affected by the Site.
One pathway, a small, open ditch, runs along the north side of the warehouse and
terminates at a culvert at Phoenix Street. It extends underground southeast of
Phoenix Street and eventually discharges into a ditch which runs along the north
side of the railroad tracks. This ditch originates along the south side of the
Burlington facility and discharges to the southeast. Three sediment samples will
be collected from these ditches, at the locations shown on Figure 2-4, to
determine if the Site is affecting surface water/sediment pathways in the
immediate vicinity.

The other pathway,· an unnamed tributary to Third Creek, is characterized as
wet-weather or intermittent, in its upper reaches, gradually becoming a
perennial, flowing stream in the lower reaches nearer Third Creek. It originates
near the intersection of Phoenix Street and West Front Street and runs south and
southwest towards Third Creek, approximately two (2) miles stream distance from
the Site.
Four (4) combination surface water and sediment sample locations will be
sampled to provide data for evaluation of any impact the Site may have had on
this drainage feature. These locations are shown on Figure 2-5. Two (2) of
these stations are located in the unnamed tributary, one (1) is located in Third
Creek upstream of the confluence of the tributary and Third Creek, and one is
located downstream of the confluence of the two streams. These samples will be
collected prior to collection of any on-site soils (Areas 2 and 3). They may be
collected concurrently with the off-site soils (Area 1).
2.1.3. Ground Water
Ground-water samples will be collected in three (3) phases. This approach
is necessitated by the general lack of data with regards to ground water flow
directions and contaminant distributions patterns. Initial phase activities will
be conducted during the initial sampling phase of the investigation. Phases II
and III may be conducted simultaneously.

two (2) deep monitoring wells installed during previous investigations, and one
(1) deep water supply well, now not in use, located on the Carnation Milk Company
property west of the site. The locations of these piezometers and wells are
shown on Figure 2-6. Specifications for the piezometers are found in Sec. 9.3
of this plan. These samples will be considered pre-well installation screening
samples and are the only ground water samples included in the sample total for
this investigation.
The analytical results for these samples will be evaluated, along with water
levels obtained from all piezometers and wells installed during the current and
past investigations, and the results of a direct push, insitu ground water
screening program to develop a ground w~ter contaminant scenario. The direct
push ground water sampling effort will constitute Phase II of the ground water
investigation and will be implemented by the ESD using a sampling technique
cu.rrently under development. These samples will be analyzed on-site, allowing
real-time development of the sampling pattern and plume delineation. Prior to
implementing this program, the specifications for this activity will be
distributed among appropriate Region IV personnel for evaluation.
The contaminant scenario thus developed will describe, to the extent
possible, the suspected contaminant distribution pattern(s) and ground water flow
directions across the site. This data will be used, in conjunction with the
known physical/chemical properties of the observed contaminants (see Table 2-1),
to develop the final monitoring well insrallation plan for the site.
After careful evaluation of this information, as well as the soils data from
samples collected during Phase I, well locations and special contruction

1 considerations, i.e., surface casing in areas of high contaminant concentrations,
will be determined and the permanent monitoring well installation program, Phase
' III of the ground water investigation, will be implemented. This program will
consist of approximately six (6) shallow and deep overburden well clusters
located both on and off site, as werl as approximately two (2) bedrock wells.
The on-site wells will be used to provide high quality samples for source area
characterization. The off-site wells will be used to determine the extent of
contamination in both the shallow, saprolite interval, as well as in the
fractured bedrock aquifer system. These estimates are subject to change, pending
the results of the Phase I and II investigations . Specifications for the
1
permanent monitoring wells are included in Sec, 9.3 of this plan. A separate,
supplementary work plan will be issued for the permanent well installation
, program, when appropriate, and will include specific well locations and
additional or refined drilling procedures, as needed.

3. REMEDIAL INVESTIGATION SAMPLING/DATA QUALITY OBJECTIVES
3.1 Introduction and Remedial Investigation Ojectives
Presently there is insufficient data available to develop a remediation plan,
if needed, for the FCXS site. Therefore, additional tasks need to be implemented
to insure adequate data is made available to develop a sound remediation plan.
The primary purpose of the remedial investigation is to obtain the additional
needed data. Specifically, the field investigation portion of the remedial
investigation will:
• Determine the areal and vertical extent of contaminated soil at the FCXS
site and adjacent properties (Carnation Milk Company, Burlington
Industries, the pre-fab utility shed lot, and the residential/business
area south of West Front Street). This aspect of the investigation will
include an attempt to locate the alleged trenches buried beneath the
warehouse.
• Determine the extent of contamination, if any, of sediment and surface
water in on-site and acljncent 'ditches, as well as in the unnamed
tributary to Third Creek and Third Creek itself.
• Verify th~ ground water contamination indicated by existing, pre-remedial
investigation on-site ground water monitoring wells.
• Determine the direction of ground water flow and develop a potentiometric
map for the site.

• Evaluate the likelihood that Burlington Industries is a major source of
the flurocarbon and purgeable halocarbon contamination observed in ground
water beneath the FCXS site.
3.2 Data Uses
Data obtained from this remedial investigation will be used for: site
characterization; evaluation of remedial alternatives; engineering design of
alternatives; conducting a risk assessment, and, potentially, enforcement (cost
recovery). Table 3-1 lists the media to be sampled and how the data will be
used.

the project manager will arrange for additional personnel (FIT, TAT, and/or Waste
Management Division) to be on-site to participate fully in the data collection
activities. Any contract personnel selected will be dedicated solely to this
site for the duration of the field activities.
4.2. Site Control and Access
The FCXS site is currently inactive, however, access to most of the site is
controlled. The driveway, off Phoenix Street, has a locking gate across it, and
there are fences surrounding most of the site except for the parking area south
of the warehouse and the area surrounding the old office building in the
sou the as tern corner of the Site. The glass in the front door is partially
1 broken, but does not appear to offer access to the warehouse. A large garage-
type door located at the eastern end of the warehouse has been partially blown
iri, and allows access to the buildings once the fenced area is entered. EPA is
currently in possession of keys to the eastern gate, as well as all of the
1 monitoring wells.
The remedial project manager will be responsible for procuring permission for
all site investigation activities, including access to neighbor's yards, the
Carnation property, the Burlington Industries facility, the pre-fabricated shed
storage east of Phoenix Street, and the Southern Railroad right-of-way. Mr.
Mallory will also be responsible for renting ancillary equipment required for the
investigation and not otherwise supplied by project subcontractors.

4.3. Field Office
An air-conditioned temporary field office (rented office trailer) will be
rented and parked on the property, the exact location to be selected in the
field. Electricity, potable water, a telephone hookup, and a refrigerator for
storing perishable materials, will be required. The trailer will be designated
as the command post during all field operations and will also be used as a
storage area for clean sampling and safety equipment and must be secure. A
portable toilet and an organic-free water system will also be necessary.
Procurement of the trailer, utilities, telephone and portable toilet will be the
responsibility of Ken Mallory, the project manager.

All persons visiting the site must sign in at the field office prior to site
entry. Site vehicle traffic will be limited to those being driven by authorized
personnel. All other vehicles must remain at a designated area near the field
office.
4.4. Sample Collection and Handling Procedures
All samples will be collected, preserved, handled and documented in accor-
dance with the ECBSOPQAM (17), which is hereby incorporated by reference. A copy
of the manual, in addition to the Project Operations 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 necessary,
these deviations will be recorded in the field log books.

Surface and subsurface soil samples collected at the same location will be
identifed using the same station number and A, B, C, etc., in the last character
position of the soil media identifier to indicate samples collected at increasing
depths, i.e., 11 C'1 is from a greater depth than 11 A11 • The following identification
system will be used.
FS -XXX -Y\.'Y
FS identifies t11e site as .ECX-~tatesville, XXX denotes the station number,
c1nd '{YY. denotes the media. Table 4-1 contains the key used to identify the
station number and media samJJlcd at a given location. For example:
FCX-123-SLD
1 would be the subsurface soil sample collected from the fourth interval sampled
at Station No. 123. Samples collected for QA/QC purposes will follow the same
general format where Y'{Y will designate the type of blank. Table 4-1 also
, contains the key to the different kinds of QA/QC samples to be collected during
the investigation. CLP spikes and blanks will be identified using media
designators, i.e., SW for surface water, to protect the blind nature of the
samp1e.

All projected samples and their locations are described in Section 2 and
shown in Figures 2-2, 2-3, 2-4, 2-5, 2-6 and 2-7. Station numbers will be
assigned consecutively from start of project to end. Samples of different media
at the same location, for example, surface water and sediment from the same
location on a stream, will be distinguished by having a different station number,
as well as a different media identifier. To insure the collection of all
proposed samples, maps indicating proposed; sample locations will be posted in the
field office. As a sample team leaves the office to collect a sample, the sample
wi 11 be high-lighted on the the sample diagram. The sample numbers will be
assigned at the office by the acting on-~ite sample custodian. The blue copy
(last page) of the chain-of-custody form will remain at the field office for
reference to insure that all samples are collected.
Tl1e project and account numbers that will be used by the field personnel
through out the field sampling portion of the investigation will be 91E-132 and
1TFA04D98M, respectively. It is vital in a project of this complexity to make
an adequate accounting of man hours expended by task. Accordingly, the Hazardous
Waste Section (H\\7S) has assigned individual project numbers to each of the
I identified tasks. The man hours expended by task are then recorded on a
' I bi-weekly time sheet by all personnel associated with the project. A co~plete
I
' , list of identified tasks and their assigned project numbers is given in Table 4-
1 i 2. Laboratory project numbers will be assigned at a later date.
4.6. Field Sampling Equipment and Cleaning Procedures
All samples will be collected with sampling equipment specified and
,decontaminated in accordance with Section 4 ~nd Appendix B of the ECBSOPQAM (17).

5. QUALITY ASSURANCE
Quality assurance (QA) procedures begin in the planning stage and continue
through sample collection, analyses, reporting and final review.
that will be used to insure data quality are discussed below.
5.1. Organization and Responsibilities
The methods
The Field Project Coordinator has overall responsibility for field QA and has
the day to day responsibility to inst1re that prescribed routine quality control
(QC) procedures are applied and documented in the field.
Laboratory analyses will be conducted either by the Analytical Support Branch
(ASB) or through the contract laboratory program (CLP), with overall
responsibility for the ASB laboratory QA resting \\'ith the the Branch Chief.
William H. McDaniel, Chief, 1norganic Section and Tom B. Bennett, Chief, Organic
Chemistry Section have the responsibility to insure that prescribed routine QC
procedures are applied and documented in the ASB laboratory. Wade Knight, Region
IV QA Officer, will ensure that QA/QC procedures are applied to any samples sent
to the CLP for analysis.
5.2. Sample Collection
All samples will be collected in accordance with Section 4 of the ECBSOPQAM
(17). The quality assurance and quality control procedures described in this

mant1al will insure that representative samples are collected from the various
media sampled.
Duplicate samples will be collected at 10 percent of the sample locations for
each matrix. This will provide a check for sampling techniques. In addition,
each week water samples are collected, water trip blanks will be prepared with
organic-free water from the field organic-free water system for extractable
organic ( including pes ticides/PCBs, herbicides and other specified organic
compounds) and volatile organic analyses. the trip blanks will be handled and
stored with the samples collected from the site. This will provide a check to
determine if somples may have been contaminated during handling, storage and
shipment. Preservative blanks ~ill be collected at the beginning of the project
and at the end of each week water samples are collected to insure the integrity
of the preservatives. An initial water sample will be collected from the field
organic-free water system prior to its use a11d analyzed for extractable organic
(including pesticides/PCBs, l1erl>icides and other specified organic_ compounds),
volatile organic compounds, meuils and cy~nicle. Subsequent samples will be
collected and ana1yzed from the organic-free \·Jdter system at the end of each week
that it is used. Equipment rinse blanks will be collected from equipment cleaned
on site, using organic-free water, at least once a week or more frequently at the
discretion of the field project manager and analyzed for extractable organic
( including pesticides/PCBs, herbicides and specified organic compounds), volatile
organic compounds, metals and cyanide. The equipment rinse blanks will be
collected to insure that the sampling equipment is properly field cleaned. Table
4-4 presents anticipated sample count by type for QA/QC samples.

5.3. Analytical Procedures
All analyses will be conducted in accordance with the Analytical Support
Branch Laboratory Operations and Quality Control Manual (ASBLOQCM) (18) or
according to the CLP Statement of Work. The ASBLOQCM describes chain of custody,
calibration procedures, routine QC checks, and data validation and reporting;
it also describes the laboratory's routine procedures for assessing precision and
accuracy.
5.3.1. Precision, Accuracy, Representativeness, Completeness,
and Comparibility
The precision, comparibility and accuracy of sample analysis is addressed i11
the Analytical St1pport Brancl, Laboratory Operations and Quality Control Manual
(ASBLOQCM) (18) and the most recent CLP Statement of Work. All samples will be
collected in accordance with the Environmental Compliance Branch Standard
Operat:ing Procedures and Oualiltv Assurance Manual (ECBSOPQAM), February 1, 1991,
(17) as may be modified by this POP, which will result in the collection of
representative samples of the various media. Completeness will be acl1ieved for
99 percent of all the samples collected (one percent may be lost as a result of
sample breakage in the laboratory or during transportation). It is also
anticipated that 99 percent of the samples :analyzed will result in valid data.
5 .4. Audits
Routine audits of laboratory activities may be conducted by the Inorganic and
Organic Chemistry Sections. Independent laboratory audits may be condt1cted by

6. SITE SURVEYING
Prior to the initiation of well installation and sample collection, the FCXS
site and surrounding adjacent areas will be surveyed by ESD and/or contract
personnel. A third order survey will be conducted of the study area to define
the boundaries of the site, as well as produce a base map. Existing structures,
sewer lines, utility right-of-ways, and property boundaries will be included on
the map. Procurement of a contract surveyor, if needed, will be the responsi-
bility of the project manager. The contract surveyor will be registered in the
State of North Carolina. A bench mark will be placed at a desirable location on
site so all sampli11g locatio11s can later be surveyed and placed on the bas~ map.
Tl1e ESD will lJe respo11sible for surveying the sampling locations, monitoring
wells, and any otl1er items of signifigance.

8. FIELD HEALTH AND SAFETY PLAN
8.1. Purpose
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 (19) manual (which is consistent with US-EPA
Orders 1440. 2 and 1440. 3) and Occupation Safety and Heal th Administrntion
regulations (29 CFR 1910.120).
8.2. Application
The provisions of this sRfety plan are mandatory for all EPA personnel and
personnel under contract to EPA involved with this investigation. Application
of this safety plan includes the sampling, drilling and associated piezometer and
monitoring well installation, and mitigation undertaken on the site or at .fillY
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 (Donald Hunter) and the safety officer (James
Gray) will have the primary responsibilities for:

1. 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 tl1e si.te operations.
~-Supervising the monitoring of safety performance by all personnel
to ensure that required work practices are employed.
5. Assuring personnel have had proper safety training before
participating in the investigatio11 and have read the Region IV,
Field Health and Safetv (19) 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 initiation of work each day, a safety

meeting may be held by the safety officer with field personnel to discuss
specific field safety operations that may apply to the day's work.
8.4. Training Requirements
All field personnel must have received a minimum of 40 hours of initial per-
sonnel protection training off site. Personµel 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 undergo a baseline
medical examination. The examination should include the basic physical
examination, heart status a11d functions (EKG), chest x-ray, pulmonary function,
blood work ( full SMAC series, hemogobin cell count and protein levels,
acetylcholinesterase activity, heavy metals -lead, cadmium, mercury, arsenic,
chromium, and selenium), liver function -f,ull 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 co11dition, visual acuity.

8.6. Site Safety Considerations
A well drilling rig will be used during the remedial field investigation.
Although it is not suspected that any waste or other material was b'uried at the
site in the anticipated monitoring well locations, drilling operations will
precede under the assumption that the possibility exists and that chemical
hazards may be e11countered during these operations. The chemicals encountered
could result in fires, explosions, and/or the liberation of irritating and
possibly toxic v,1pors. It is felt that the likelihood of this occurring is very
remote. However, prior to the initiation of the site investigation, the City of
Statesville Fire Department and first response unit will be notified by the field
project coordinator. They will be notified far enough in advance so they may be
adequately prepared to respo11cl to a11y emergencies that may arise at the site.
The emergency p11one numbers and the route to the nearest hospital will be posted
conspicuously at the field office. It is the responsibility of the safety
officer to e11sure that all fi.eld personnel know the route to the hospital and
have a copy of the emergency phone numbers.
8.7. Identification of W~ste Material on Site
The known contaminants of primary concern on site are pesticides, purgeable
halocarbons and polynuclear aromatic hydrocarbons. The specific compounds are
listed in Table 8-1. Additional purgeable halocarbons and polynuclear aromatic
!1ydrocarbon have bee11 identified as being present but below detection limits in
data generated from previot1s sainpling at the site. Appendix A contains material
safety data sl1eets and si1nilar information for all known quantifiable contam-
inanes at the FCXS site.

8.8. Site Monitoring and Routes of Exposure
During various phases of tl1e drilling and sampling activities, the site will
be monitored with a photoionizaton detector (HNu or TIP II) using a 10.2 EV lamp,
an organic vapor analyzer (OVA), a radiation survey meter and/or a combustible
gas meter/oxygen meter. It will be the safety officer's responsibility to
determine what level of monitoring will be required for each sampling event.
Table 8-2 lists the action levels for each of the air monitoring instruments/-
meters. If readings on the instruments/meters exceed those listed in Table 8-2,
then the personnel must disco11tinue field operations and return to the field
office to discuss the findings with the safety officer.
It .is felt that pesticide and herbicide ~ontamin_ated dust and airborne soil,
present primarily if conditions ~re dry on site, constitute the greatest known
chemical risk to field personnel conducting soil sampling outside of the confines
of the warel1ol1se 1Juilding. Routes of exposure for these waste would include
inh.1 lat ion, ingestion and derma 1 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. It is felt that the greatest
exposure risks will occur during drilling of downgradient monitoring wells,
during subsurface soil sampling 011 the southern portion of the site, and during
soil sampling activities conducted inside the buildings. If conditions are
particularly dusty in these areas, combination dust/organic cartridges on
full-face respirators will be required.

personnel by using the air monitoring equipment.
8.10. Emergency Contingency Plan
011-site e1nergencies could l)e expected to result from fire, che1nical exposure
or personnel casualty. If a11 incident occurs necessitating a response to an
e1nergency, 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 1 second duration).
Personnel on site will immediately discontinue field operations and assemble at
the field office (command post). The emergency numbers will be posted at the
field office. Appendix B contains the stand-alone site safety plan with emergency
pl1one numbers, as well as directions and a map to Davis Hospital, one 1nile east

9. DRILLING, PIEZOMETER AND MONITORING WELL CONSTRUCTION SPECIFICATIONS
9.1. Monitoring Plan
Drilling related monitoring activities at the FCXS site will include the
installation of four (4) piezometers during Phase I activities and an
undertermined number of monitoring wells during subsequent phases of the
investigation. The locations of the proposed piezometers is shown on Figure 2-3.
The number and placement of monitoring well locations, as well as the need for
shallow and deep surficial well clusters, will be determined after evaluating
water level data and ground water contaminant data from the piezometers and
existing monitoring wells and insitu samples collected during Phase II activity
at the site.
The piezorneters will be installed at selected soil sampling locations at the
site. After completion of soil sa1nple collection at each location, tl1e borehole
will be completed to refusal, interpreted as bedrock. File information for the
existing monitoring wells indicates refusal occurrs between fifty (50) to seventy-
five (75) feet below land surface (BLS). Water levels in these wells range from
about thirty-five (35) feet to about forty-five (45) feet BLS.
Based on this information, it is anticipated that the piezometers will be
completed with fifteen (15)-feet of screened interval after reaching refusal. The
piezometers will be constructed using 2-inch diameter, Schedule 40 polyvinyl
chloride (PVC) casing and No. 10 slot PVC screen. Each piezometer will be packed
with twenty (20) feet of 30/40 mesh Ottawa sand, sealed above the sand pack with
bentonite pellets and grouted, from the top of the pellets to the surface, with

a pure, high solids bentonite grout. The grout will have a weight of 9.4 lbs/gal.
After allowing the grout to set overnight, a minimum two-feet diameter, four-inch
thick concrete pad will be poured and fitted with a locking protective cover. A
schematic of a typical piezometer is presented in Figure 9-1.
After water levels have stabilized in the piezometers, water levels will be
obtained for all wells and piezometers on site and ground water flow directions
will be ascertained. Based on both this evaluation, and the results of the insitu
ground water screening, an appropriate number of shallow, and if appropriate, deep
surficial permanent monitoring wells will located. It is anticipated that up to
two (2) bedrock wells will also be needed to evaluate off-site migration in the
fractured bedrock portion of the aquifer. These wells will be installed during
a subsequent phase of the investigation. Construction of the permanent surficial
monitoring wells will be si1nilar to that of the piezometers.
The permanent surficial wells will be constructed, however, using 2-inch
diameter stainless steel risers and screens. The deep wells will be constructed
using 4-inch diameter stainless steel riser grouted in place above an open-hole
interval, Stainless steel wi.11 be used for the monitoring wells because of the
known contaminants and the long-term duration of the 1nonitoring system. Addi-
tionally, each permanent monitoring well will be completed with a locking
protective casing installed into the concrete pad. A schematic of a typical
monitor well cluster is presented in Figure 9-2. A schematic of a typical deep,
bedrock well is presented i11 Figure 9-3.

9.2. Scope of Work
The scope of work for drilling services is as follows:
Phase I
• Install four (4) Schedule 40 PVC piezometers to depths of approximately 50
feet.
• Collect split-spoon (ASTM Method 1586) or equivalent samples at each
piezometer location. Five samples will be collected at each location,
beginning at the Sl1rface and continuing at five foot intervals to a depth
of 22 (twenty-two) feet. The driller should be prepared with at least
five (5) standard-cleaned (according to the Region IV ECB SOPQAJ-1 (17) and
adequately air-dryed split-spoons at each well, e.g., no cleaning of split
spoons used to collect samples for chemical analyses will be allowed at
the well site. After a]l samples to be analyzed are collected, t.he spoons
1nay the11 1,e c].eaned 3t tl1e well site and used for logging purposes and
collection of samples for physical characteristic testing.
• Collect soil samples from approximately 40 feet BLS to be used for soil
classification. This information will be used to select the appropriate
screen size for tl,e permanent monitoring wells.
Phase II
• Drilling activity during Phase II will consist of solid and/or hollow
stem augering to support the direct push sampling effort. It is
anticipated that at1gers will be used to complete boreholes to within two

augers or center stems will be pulled and the insitu sample tip driven
to the samping interval. As this methodology is currently under
development, no more detailed specifications will be provided in this
project operations plan.
Phase II I
• Install approximately six (6) permanent ground water monitoring well
clusters, 2-inch diameter stainless steel riser and screen, approximate
•
depths of 50 (fifty) and 70 (seventy) feet.
Install two (2) permanent bedrock ground water monitoring wells, 4-inch
diameter stainless steel riser grouted in-place at bedrock/regolith
interface (approximately 80 feet BLS) and completed open hole to an
anticipated depth of approximately 125 feet BLS.
9.3. Technical Specifications for Drilling Operations

9.3.2 Piezometer Specifications
The piezometers shall be constructed with Schedule 40 PVC threaded, flush-
joint riser and screen (0.010 in. slots) extending 2-ft., 6-in. above surface.
All piezometers will have a threaded plug on the bottom of the screen, a vented,
threaded cap, and protective casings. 0-rings will be removed and all threads
taped with Teflon® tape.
All piezometers shall be installed using 6.25-inch I.D. hollow stem augers.
The piezometers will be co11structed inside the hollow stem as they are slowly
being retracted. The piezometers will be screened with approximately 15-20 feet
of 2-inch diameter screen (0.010 in. slots). The screen will be delivered to the
site in 5 foot sections and will be combined, as necessary, to meet the screen
requirements at each locatio11. The driller should have a minimum of 80 feet of
screen (sixteen (16) 5-foot sections) delivered to the site to meet these
reqt1irements. Likewise, it i.s anticipated tl1at approximately one-hundred (100)
to one-hundred and sixty (160) feet of casing/riser will be required to complement
the screens for all of the piezometers. The casing lengths should be a mix of 10
foot and 5 foot sections. The threaded flush joint riser will extend to approxi-
1nately 2-ft., 6-in. above the surface. A clean, bagged silica sand pack, sized
for use with 0.010 inch slot size screen, will be placed, via tremie pipe, in the
annulus to a depth of five (5) feet above the screen. A bentonite pellet seal,
minimum two foot thickness, will be placed, using the tremie tube, above the sand
pack. The elevations of the top of the sand pack and the bentonite pellet seal
will be constantly checked using a weighted tape or 11 tag line 11 to insure that the
cons true tion spec i fie a tions a re met. Organic-free water will be added, if needed,
to hydrate the bentonite pellets in the absence of formation water. A high

solids, pure bentonite grout, mixed to a weight of at least 9.4 pounds per gallon,
will be used to fill the annulus from the bentonite seal to within 2-ft. of the
surface. The grout will be pumped, via tremie tube, into the annular space and
will be emplaced from the seal upward. Through the use of elbows on the end of
the tremie tube, reduction of pumping velocities, or other means, efforts will be
made to reduce the potential for jetting of the bentonite pellet seal during
grouting. A mud balance will be used to check the weight of the grout exiting the
annulus, after the last auger is extracted, to insure that the hole is
satisfactorily grouted. After Che grout has set, the wells will be finished off,
as described i11 detail below, with a concrete pad and locking, protective casing.
All wells will have minimum 4-inch square steel protective casings with
vented, hinged, locki.ng well cover and 3-ft. square concrete (3-ft. square by
6-i11. thick) pads a11d per1na11e11t J.D. tags. Pads will have an edge thickness of
6-in. but should be thicker ne.:,r the protective casing, i.e. pads should be sloped
to promote runoff. A one-qttarter inch hole should be drilled, on opposite sides,
in the protective casing, at the base of the stickup, to allow water drainage from
inside the protective casing. The pads will extend two feet down into the borehole
or to the frost line whichever is greater and be bonded to the grout . Three
concrete-filled steel pipe bull.ards (bumpers), 3 to 4-inch diameter and 3-feet
high, will be installed in ectch pad.

surface. All wells will have a threaded plug on the bottom of the screen, a
vented, threaded cap, and protective casings.
All wells shall be installed using 6.25-inch I.D. hollow stem augers. These
wells will be constructed inside the hollow stem as they are slowly being retract-
ed. The wells will be screened with approximately 10 to 20 feet of 2-inch dia-
meter screen. Screen slot size will be determined after geotechnical evaluation
of soil collected from the anticipated scre~ned interval. The specified screen
will be delivered to the site in 10-feet and 5-feet sections and will be combined,
as necessary, to 1neet the screen requirements at each location. F6r the currently
anticipated number of wells, the driller should have a minimum of 120 feet of
screen delivered to the site to meet these requirements. Likewise, it is
anticipated that approximately 600 feet of casing/riser will be required to
co1nplement the screens for all wells. The casing lengths should be a mix of 10 -
foot and 5 foot: sections. The threaded flush joint riser will extend to
approximately 2-ft., 6-in. above the surface. A clean, bagged silica sand pack,
sized for use with the specified screen slot size, will be placed, via tremie
pipe, in the annulus to a depth of at least one foot above the screen. A
bentonite pellet seal, minimum two foot thickness, will be placed, using the
tremie tube, above the sand pack. The elevations of the top of the sand pack and
the bentonite pellet seal will be constantly checked using a weighted tape or "tag
line'' to insure tl1at the construction specifications are met. Organic-free water
will be added, if needed, to hydrate the bentonite pellets in the absence of
formation water. A high solids, pure bentonite grout, mixed to a weight of at
least 9.4 pounds per gallon, will be used to fill the annulus from the bentonite
senl to within 2-ft. of t\1e surface. The grout will be pumped, via tremie tube
into the arinular space and will be emplaced from the seal upward. Through the use
of elbows on the end of the tremie tube, reduction of pumping velocities, or other

means, efforts will be made to reduce the potential for jetting of the bentonite
pellet seal during grouting. A mud balance will be used to check the weight of
the grout exiting the annulus, after the last auger is extracted, to insure that
the hole is satisfactorily grouted. After the grout has set, the wells will be
finished off, as described in detail below, with a concrete pad and locking,
protective casing.
All wells will have minimum 4-inch square steel protective casings with
vented, hinged, locking well cover and 3-ft. square concrete (3-ft. square by
6-in. thick) pads a11d perma11ent I.D. tags. ,Pads will have an edge thickness of
6-in. but should be thicker nedr the protective casing, i.e. pads should be sloped
to promote runoff. A one-qunrter inch hole should be drilled, on opposite sides,
in the protective casing, at tl1e base of thJ stick-up, to allow water drai11age
from inside the protective casing. The pads will extend two feet down into the
borehole or to the frost line whichever is greater and be bonded to the grout.
Three concrete filled steel pipe bumpers, 3 to 4-inch diameter and 3-feet high,
will be installed in e~ch p~d.
Bedrock Monitoring Well Drilling Specifications
The wells shall be constructed with stainless steel riser grouted in-place
withi11 a minimum of three feet of competent bedrock below the regolith/bedrock
boundary. The riser will be threaded, flush-joint casing extending 2-ft., 6-in.
above surface. All wells will have a vented, threaded cap, and protective casings
set in concrete pads, as described below.
The regolith/overburden and the first three (3) feet of competent, unweathered
bedrock will be drilled using mud rotary with a.nominal 8-inch tri-cone rock bit.

After the borehole is completed to this depth, mud will be cirulated to clean the
hole of all rock fragments. The well casing will then be installed with a grout
shoe placed at the lower end of the casing. The well casing/grout string assembly
will be raised enough to allow pumping of grout. The annular space between the
casing and the borehole will then be pressure-grouted with a cement/bentonite
grout through the grout shoe until all mud is flushed from the annulus and grout
is observed. When grout is seen exiting the surface, the casing will be seated
in the bottom of the recess in the bedrock surface and.the grout string removed.
After the grout string is removed, the well will be checked periodically to ensure
that 110 grout is leaking into the riser. Mud or water may be added to prevent
grout from flowing back into the riser. rf'used, it should be flushed from the
riser and discarded prior to completion of the well.
The grout will be allowed to cure for at least 24 hours. After the grout has
set, drilling will continue using water and a nominal 3-inch diameter diamond
coring bit. Drilling will contint1e until significant secondary permeability
features (fractures, open schistose or gneissoid textures, etc.) are observed in
the cores. At these indications, drilling will cease and water will be removed
from the borehole by air, bailing or pumping and the recovery observed. The EPA
geologist will, based on tl1ese recovery observations, make the determination to
cease or continue drilling. At the completion depth, the well will be flushed of
all drilling materials and completed on the ~urface.
All 4-inch wells will have minimum 6-inch square steel protective casings with
vented, hinged, locking well cover and 3-ft. square concrete (3-ft. square by
6-in. thick) pads and permanent I.D. tags. Pads will have an edge thickness of
6-in. but should be thicker near the protective casing, i.e. pads should be sloped

to promote runoff. A one-quarter inch hole should be drilled, on opposite s_ides,
in the protective casing, at the base of the stick-up, to allow water drainage
from inside the protective casing. The pads will extend two feet down into the
borehole or to the frost line whichever is greater and be bonded to the grout.
Three concrete filled steel pipe bumpers, 3 to 4-inch diameter and 3-feet high,
will be installed in each pad. Figure 9-3 is a schematic of the proposed ~ypical
bedrock well installation.
9.3.5 Miscellaneous Drilling Specifications
The driller should be prepared to water-rotary advance all specified auger-
drilled boreholes if deemed 11ecessary by the site geologist. If subsurface
conditions exist so that water rotary cannot be utilized, mud rotary will be
substituted.
The driller shall supply a tank (truck or trailer mounted) for potable water
used for drilling, mixing grout, tre1nming sa11d, equipment decontamination, etc.
The tank shall be clean and free of all foreign matter and will be subject to the
on-site decontamination procedures and quality control protocols. The driller
will be responsible for making arrangements to obtain potable water for drilling.
All grout will be mixed in a manner to assure a uniform product. Suitable
methods include commercially available grout mixers and stock tanks with high
pressure/high volume circulation systems (tr,ash pumps or diaphram pumps). Other
methods will be considered for approval by the on-site EPA geologist.

9.3.6. Plugged and Abandoned Wells
If any boreholes are deemed unsuitable for monitoring installation by the
on-site geologist, the driller will plug and abandon the borehole as required by
state regulations or as directed by the EPA geologist. Abandonment would
typically involve grouting the entire borehole with cement or other another
acceptable grout mixture.
9.3.7. Boring Log
Tl1e purpose of this log is to provide EPA with a record of the dimensions of
the hole, drilling methods used, any drilling problems encountered, and the
general character of the subsurface material pe11etrated. The log will include the
following:

The driller will also keep a record of the construction design, materials, and
amounts· of materials used in each monitoring well. This will include diameter of
casing, depths and lengths of all well screens, type of screen pack, and location
of screen packs. Other data may be requested by EPA. This record will be due at
the completion of the project.
9.4. Decontamination
The driller will furnish the necessary equipment and manpower to perform all
on-site decontamination. The drill rig should be cleaned and prepped prior to
arrival on-site all grease a11d oil removed, all hydraulic fittings secure, etc.
EPA will inspect all down-hole equipment prior to usage.
drilling equipment will be performed between each hole.
Decontamination of
The driller will be
required to have 011-site two sets of down hole drilling and sampling equipment
(auger flites, bits, split spoon samplers, etc.) to decrease standby time during
the drilling operation.
If any sampling equipment is used to collect samples tl1at contain oil, grease,
or other hard-to-remove materials, it may be necessary to rinse the equipment
several times with pesticide grade acetone or hexane to remove the materials
before proceeding with site decontamination procedures. These conditions are not
anticipated at the FCXS site, however. If down hole drilling equipment is
painted, badly rusted, or coated with materials that are difficult to remove, it
will be required to steam clean, wire brush, or sandblast the equipment before
proceeding. This is to be performed before mobilization to the job site. Any
sampling equipment that cannot be cleaned I using these procedures should be
discarded. The driller will supply a decontamination team, staffed separately
I
I

I
I

from the dril 1 ing team, so that decontamination can precede concurr_ently with
drilling. The team will follow the direction of the EPA geol~gist or other
on-site EPA or EPA authorized personnel, as appropriate.
Normally, any portion of the drill rig, backhoe, etc. that is over the
borehole (Kelly bar, or mast, backhoe buckets, drilling platform, hoist or chain
pulldowns and/or cathead, etc.) must be steam cleaned and wire brushed before
being brought on site to remove all rust, soil and other material which may have
come from other hazardous waste sites. The drill rig should then be inspected to
insure that all oil, grease, hydraulic fluid, etc. has been removed, all seals and
gaskets are intact and no fluids are leaking.
Steam cleaning of the drill rig is then required prior to drilling each
borehole. In addition, all downhole drilling, sampling, and associated equipment
that will come into contact with the downhole equipment and sa~ple medium shall
be decontaminated by the following procedure, as specified in the Region IV
ECBSOP/OAf!. February 1, 1991. A copy will be provided, if requested.
1. Clean with tap water and laboratory grade detergent, using a
brush, if necessary, to remove particulate matter and surface
films. Steam cleaning may be necessary to remove matter that is
difficult to remove with the brush.
2. Rinse thoroughly with tap water.
3. Rinse thoroughly with deionized water.

4. Rinse twice with solvent (pesticide grade isopropanol).
5. Rinse thoroughly with organic-free water and allow to air dry
as long as possible. If organic-free water is not available,
allow the equipment to air dry as long as possible. Do not
rinse with deionized or distilled water.
NOTE: Organic-free water can be processed on site by purchasing
or leasing a mobile deionization-organic filtration system.
NOTE: Tap water may be applied with a pump sprayer. All other
decontamination liquids (D.I. water, organic-free water, and
solvents), however, must be applied using non-interferring
contai11ers. These containers will be made of glass, Teflon, or
stainless steel. No plastic containers or pu1np sprayers will
be allowed. This aspect of the decontamination procedures used
by the driller will be inspected by the site geologisf prior to
beginning of operations.
6. Wrap with alumninum foil, if appropriate, to prevent
contamination if equipment is going to be stored or
transported. Clean plastic can be used to wrap augers, drill
stems, casings, etc. if they have been air dryed.
7. As previously stated, all downhole augering, drilling and
sampling equipment shall be sandblasted before Step #l if there
is a buildup of rust, hard or caked matter and/or painted

equipment. All sandblasting shall be performed prior to arrival
on site. All equipment shall be subject to inspection by EPA
upon arrival on site.
Decontamination of all equipment shall occur at a decontamination pit, either
excavated or built above grade. The pit and surrounding area will be lined with
heavy duty plastic film of sufficient width to provide a seamless, lapless liner
for the pit. All cleaning of drill rod, aug'er flights, well screen and casing,
etc. will be conducted above the plastic film using saw horses or other
appropriate mea11s.
As the pit is filled, the water will be pumped by the driller into drums for
proper disposal. EPA will assume responsibility for disposal of this material
as described in Section 10 of the Project Operations Plan.
No solvent ri11sates will lJe placed in the pj_t_ All solvent rinsates will. be
collected in separate containers and handled by EPA in accordance with the
procedures specified in Sectio11 10 of the Project Operations Plan.
9.5. Monitor Well Development
Monitor wells must not be developed for a period of 24 hours after
installation. All installed wells shall be adequately developed prior to initial
sampling efforts. Adequate development should eliminate all fine material from
the area of the well screen, and allow for the collection of a sample which is
as free as practical of suspended materials and is clear as achievable.
Depending on the nature of the overburden, wells installed in this material may

not develop to absolute clarity; slight turbidity will be allowed if the driller
can demonstrate that the development method chosen is suitable for the conditions
and a point of diminishing returns has been reached with development efforts.
Wells installed in bedrock should develop to a high degree of clarity.
Various methods may be used to develop wells at the FCXS site. These methods
consist of pumping, bailing, lifting the water column with compressed air,
plunging-surging, etc. If compressed air is used, the air must be filtered to
remove all oil and grease. The driller must periodically measure the pH and
specific conductance of water removed during well development to evaluate the
adequacy of development. This information will be recorded in a log to be
relinquished to the EPA project geologist after all development is completed.
All materials introduced into the wells during development, such as air lines,
pumps, etc. will be subject to decontamination procedures.
9.6. On-site Waste Storage and Disposal
At the direction of the EPA representative, and in compliance with all
fede1·al, state, and local rules, regulations, and permit requirements, any and
all wastes (cuttings, develop111ent water, decontamination wastewater, etc.) which
have been generated due to this contract will be containerized in 55-gallon drums
and left on site. These investigation derived wastes will be evaulated and
handled according to the Investigation Derived Waste Management Plan included as
Section 10 of the Project Operations Plan.

Upon completion of all work described in these specifications and after
decontamination, the driller shall also remove from the site all containers,
drums, tanks, debris, and unused materials, and restore the site as close as
practicable to its condition prior to conimencement of the work provided for
herein. The driller should schedule the use of a dumpster through a local waste
management firm to collect waste generated during the drilling project. All
walks, drives, utilities, structures, or other property damage due to the
driller's negligence shall be restored at his expense to as nearly as possible
their original conditions. Payment for work shall not be completed until the EPA
representative approves the cleanup at the completion of the work.
9.8. Site Restoratio11
The drilling site shall be restored as close as possible to the original
condition prior to drilling. No trash, fluid, or other foreign materials shall
remain at drilling sites. Drilling sites will be restored immediately after
completion of tl1e borehole at that particular site. The boring and/or monitor
well will not be considered co1nplete for payment until the EPA representative
approves the drill site restoration in his daily or weekly report.
9.9 Health and Safety
The driller and all responsible parties under his/her supervision must adhere
to the site Health and Safety Plan (HASP), to be provided by EPA upon award of

obtained a comprehensive medical-physical examination (or equivalent)
within one year prior to the date scheduled to work on an EPA site.
This physical examination must include tests to certify an employee's
ability to wear a respirator. Before commencing work and within five
calendar days from date of field mobilization, the driller will be
required to provide EPA with a physician's statement medically
qualifying each employee.
• EPA will conduct a fundamental Health and Safety meeting for the
driller's employees their first day on-site. This meeting is not a
substitute for the 40 hours of OSHA required training.
9.13 Support of Commu11ity Relations
The driller shall make every effort to maintain good relations with adjacent
property owners and occupants. All on-site drilling personnel should be made
thoroughly cognizant of the importance of this aspect of the work and its
sensitivity to the entire program, as well as to th~ successful completion of
their particular assignme11t.
All field activities sl1all be conducted in an efficient and professional
manner, with minimum practical damage to the site environment. Thus, tree and

brush removal and similar impacts upon the existing site environment shall be
limited to only those approved by EPA.
9.14 Project Schedule
The driller shall make every effort to maintain the schedule. The driller·
shall base the cost estimate on 10-hour days, 10 days on, 4 days off. The
driller shall be willing to mobilize to the project site within two weeks of
notification from EPA.
9.15 Cost Estimate
The cost estimate must be in unit form to include a unit-price breakdown.
All payments will be on actunl footages obtained in the field. All well
materials will be supplied by the driller. The driller must obtain all permits
and legalities that are necessary from the proper authorities and shall have all
the current and necessary licenses and registrations required by state and local
authorities.
The driller's cost estimate will be written under the assumption of work to
be performed in Level D protection.
9.16 Measurement and Payment
At the satisfactory completion of all of the work described herein, the EPA
geologist will recommend payme11t on receipt of the driller's invoice and other
requested documentatio11. If Level C protection is required for on-site work

SECTION 10. INVESTIGATION DERIVED WASTE MANAGEMENT PLAN
10.1 General
During the course of the investigation, a variety of investigation derived
wastes (IDW) will be generated which may require special management and
disposition. The following is a description of the anticipated types of IDW
followed by the protocol to be followed t~ evaluate the handling a disposition
of these wastes.
10.2 Investigation Derived Waste Categories
10.2.1 Drilling Waste
All drill cuttings generated during piezometer and well installation will be
containerized in 55-gallon drums. Any cuttings generated at a location beyond·
the controlled access portion of the site will be transported to a secure area
of the site. Cuttings generated within the. secure area may be containerized and
stored at the drilling location. At approximately five-foot intervals during
drilling, a sample of the auger cuttings will be collected and retained in a
glass pan. After the borehole is completed, anticipated to be at a depth of
approximately 50 feet, a composite sample will be prepared from all of the five-
foot soil aliquots. Any subsequent borings completed within 10 feet of a
previous boring will not have to be sampled for waste disposition purposes.

10.2.2 Monitoring Well Development and Purge Water
All water generated during development and purging of monitoring wells
installed during the remedial investigation will be containerized in 55-gallon
drums. This water will be held in a secure location on site until analyses are
completed for the first round of ground water sampling. If analyses of samples
collected during the first round of samples indicates that ground water from a
particular location does not pose a substantial threat to human health or the
environment, purge water from subsequent sampling events may be discharged
directly to the ground no less than ten feet from the monitoring well.
10.2.3 Decontamination Pit Conten~s
All water generated during decontamination of the drill rig and other
equipment will be co11tained wit\1in a decontamination pit lined with heavy duty
plastic. At the end of each day, or as the pit becomes full, the contents of the
pit will be pumped into 55-gallon drums. At the completion of all site sampling.
activities, a composite sample will be prepared from a random sample of one-half
of all drums containing aqueous decontamination fluids.
10.2.4 Waste Solvents
It is anticipated that isopropanol, generated during solvent rinsing of
sampling equipment, will comprise the majority, if not the sole constituent, of
this category. All solvent rinsing will be conducted over galvanized wash tubs
or other large containers in such a manner that all solvents are recovered. All
solvent remaining in the co11tainer at the end of the day will be re-containerized

in the original one-gallon jugs, placed in the factory shipping boxes and
returned to the ESD laboratory. This material will be bulked with other waste
isopropanol and entered into the laboratory's hazardous waste tracking system for
appropriate disposal.
10.2.5 Clothing and Miscellaneous Trash
Significant amounts of soiled Tyvek, gloves, paper towels, and other site-
related trash will be generated during the course of the investigation. It is
not anticipated that this material will constitute a significant threat to human
health or the environment and, as such, it will be placed in large capacity
plastic garbage bags. As these garbage bags are filled, the tops will be twisted
a11d securely taped. A commercinl dumpster will be contracted for the duration
of the investigatio11. All waste generated within this category will be placed
in the dumpster.
10.3 Evaluation of Analytical Results of Investigation Derived Waste
After all IDW analytical results are received, the data will be submitted to
the R_isk Assessment Officer (RAO), Waste Management Divison, for evaluation. If,
in the opinion of the RAO, any of the IDW would pose a substantial or significant
risk to human health or the environment if discarded to the ground at the site,
it will be managed as a hazardous waste and sent to a RCRA-approved hazardous
waste disposal or treatment facility. If the material poses no risk, it will be
applied to the land surface wi.thin the secure eastern area of the FCXS site.
