1,0 INTRODUCTION
Bechtel Environmental, Inc. (Bechtel) has.been assigned by the
U.S. Environmental Protection Agency (EPA), Region IV, under Work
Assignment No. 03-4L3L, to perform a remedial investigation/
feasibility study (RI/FS) at the JFD Electronics/Channel Master
(Channel Master) site, Oxford, North Carolina.
This field operations plan (FOP) describes the logistics of the
field tasks to be performed, as outlined in the work plan, to
conduct a remedial investigation at the Channel Master site in
accordance with the above EPA work assignment. The FOP will be
coordinated with the quality assurance project plan (QAPP), which
outlines the quality assurance and quality control (QA/QC)
protocols and the health and safety plan (HSP).
1,1 Project Overview
Electroplating operations were conducted at the Channel Master
site (shown in Figures 1-1 and 1-2) between 1968 and 1979 by JFD
Electronics (JFD). These operations resulted in the generation
of electroplating wastes including metal-contaminated sludge and
wastewater. A lagoon covering approximately 23,400 ft2 was used
to dispose of sludge.
In 1980, Channel Master bought the site from JFD/Unimax and in
the spring of 1981, began manufacturing indoor antennas and
satellite dishes. Some organic solvents such as 1,1,1-
trichloroethane (TCA) were used on-site for cleaning. Volatile
organic compounds (VOCs), which reportedly originated from a
concrete waste oil tank and chemical storage area, were also
released at the site during these operations.
Based on the evaluations of a limited soil and groundwater
investigation conducted by Channel Master, certain cleanup
actions including removal of sludge from the containment lagoon
and removal of two fuel oil tanks and one concrete waste oil tank
from the south side of the main building were carried out by
Channel Master in cooperation with the North Carolina Department
of Human Resources -CERCLA Unit (NCDHR-CERCLA) during 1987 and
1988. Areas affected by these efforts are south of the main
building, as shown in Figure 1-3. Site visits were conducted by
representatives of the Agency for Toxic Substances and Disease
Registry (ATSDR) in March 1989 and later by EPA in September
1989. Based on these inspections, both agencies concluded that
residual contamination from Channel Master's cleanup efforts may
remain at the site.

2.0 FIELD INVESTIGATION PROTOCOLS
2.1 Objectives
The main objective of this field investigation is to identify the
nature and extent of contamination at the Channel Master site.
All field operations conducted in support of this program will be
completed in accordance with procedures presented in EPA Region
IV, Engineering Support Branch Standard Operating Procedures and
Quality Assurance Manual (ESB SOPQAM (April, 1986)), included as
Appendix A. For those activities not included in the ESB SOPQAM
(April, 1986), site-specific procedures developed for the Channel
Master site will be followed in close accordance.
The following sections describe the field investigation protocols
for the Channel Master site characterization.
2.2 Mobilization and Preparatory Activities
2.2.1 General
The following mobilization and preparatory activities will be
initiated prior to the field investigation. These activities
include:
• Bechtel will meet with representatives of Channel Master
prior to field activities to discuss logistics of the field
work and placement of the field trailer, etc.
• Reviewing the historical development of the site area to
identify occasions when quantities of contaminated soils or
other materials may have been disturbed or carried from the
site.
• Examining aerial photographs, maps, and other historical
documents to identify events that may have resulted in the
disturbance of soils or structures.
• Examining utility maps and building permits to determine
dates of construction activities.
• Procuring subcontractors.
• Obtaining EPA approval and procuring equipment i.e.,
personal protective ensembles, air monitoring devices,
sampling and analysis equipment such as a field-operable gas
chromatograph (GC), decontamination apparatus, procuring
supplies (disposables, tape, notebook, etc.), and ensuring
proper calibration of instrumentation.

• Ensuring that site personnel are medically qualified and
properly trained to work on a hazardous waste site and
according to specific requirements for the Channel Master
site.
• Coordinating with the EPA Region IV RPM regarding scheduling
the CLP lab and obtaining CLP paperwork. Bechtel will
provide sample tags, custody sheets, and safety seals.
• Procuring on-site facilities for office and laboratory
space, decontamination equipment, vehicle maintenance and
repair, and sample storage, as well as on-site water,
electric, telephone, and sanitary utilities.
• Providing for storage of decontamination solutions, drilling
muds cuttings, purge and development water, and spill-
contaminated material.
• Bechtel will establish a fenced area (approximately 100 x
100 ft) within Channel Master property to store drums of
drilling spoils, and well development and purge water.
Preparation prior to entering the field is a prerequisite to an
orderly and complete sampling schedule. A substantial portion of
the sampling procedure consists of gathering and cleaning
equipment, collecting and labeling sample containers, and
completing necessary forms (e.g., chain-of-custody forms).
2.2.2 Standard Cleaning/Decontamination Procedures
All sampling equipment (e.g., hailers), drilling, testing
(field), and well-installation equipment will be cleaned and/or
decontaminated in accordance with procedures outlined in EPA
Region IV, ESB SOPQAM (April, 1986), Appendix B, Standard
Cleaning Procedures. Personal protective equipment will be
decontaminated as described in the HSP.
2.2.3 Analytical Requirements
Table 2-1 is a summary of the number of proposed samples and the
corresponding analytical requirements. The sample locations are
shown in various figures in the following sections.
Approximately forty groundwater samples obtained by using a
hydrocone-type technique will be analyzed for the specific
volatile organic contaminants (VOCs) previously detected at the
site as a preliminary screening tool. Surface and subsurface
soil, groundwater, surface water and sediment samples will be
analyzed for Target Compound List (TCL) contaminants including
volatiles, semi-volatiles and metals. In addition, samples will
also be analyzed for dissociated cyanide which has been
previously detected at the site. Analysis for dissociated

cyanide will also be beneficial when evaluating treatment
technologies. Groundwater and surface water samples will
additionally be analyzed for standard water quality parameters
(i.e. pH, conductivity, and temperature).
All samples (aqueous and solid) will be analyzed for hexavalent
chromium. The toxicity characteristic leaching procedure (TCLP)
will be used to determine the mobility of organic and inorganic
contaminants in the soil samples.
The TCLP was recently promulgated (55 Fed. Reg., No. 61, March
29, 1990, pp. 11798-11877), replacing the Extraction Procedure
(EP-Toxicity) leach test. The newly mandated procedure regulates
as hazardous those wastes whose leachate exceeds regulatory
threshold concentrations of any one of 25 organic toxicants, as
well as 14 toxic constituents already regulated. The TCLP
differs from the EP-Toxicity test by stipulating exact procedures
and test equipment, specifically, use of a zero-headspace
extractor (ZHE). The ZHE is used to prevent sample contamination
and to eliminate misleading results in the extraction procedure
for voes which evaporate easily. Overall, TCLP procedures and
analyses basically remain the same as EP-Toxicity, but are more
controlled, more standardized, and require less interpretation.
2.3 Sample Identification Procedures
2.3.1 Identification Code
A coding system will be used to identify each sample taken during
the field investigation. The system will allow quick data
retrieval and tracking to account for all samples and will ensure
that each sample has a unique identification. Each sample
identification number is composed of four components:
• A two-letter designation will be used as a general site
identification. The site code for the Channel Master Site
is CM.
• A two-letter designation will be used to indicate the sample
type and would have the following meaning.
SW -Surface Water
so -Sediment
GW -Groundwater
ss -Surface Soil
SB -Subsurface Soil
HC -Hydrocone-type Sample
• A station-specific designation is used to identify the
station at which the sample is being taken as given below:
BH5 -borehole number 5
10
I
I
I
I
I
I
I
I
I
SPl -sludge pit station 1
• A three-number designation will be used to number samples
according to sample type. The samples are numbered
consecutively within the type and are not related to the
date of collection. As an example, a sample code follows:
CM-SB-SPl-001
(Channel Master -Subsurface soil sample -collected at
sludge pit station 1 -first subsurface soil sample from
sludge pit station 1)
• The depth of the SD, SB, and HC samples will be included on
the sample tags and chain-of-custody forms.
More information about the type of sample and purpose of sampling
will be recorded in the field logbook.
2.3.2 Field Logbook
All information pertinent to field surveys and sampling will be
recorded in the field logbook. This logbook will be bound, such
as a standard laboratory notebook. Field logbooks will be
maintained in accordance with EPA Region IV ESB SOPQAM (April,
1986). I 2.3.3 Sample Analysis

Table 2-1 provides a summary of the number of proposed samples
and the specific analyses required for each sample.
2.4 Land survey
2.4.1 Objective
A visual survey will be conducted to update existing maps of the
Channel Master site and immediate vicinity. Any new pertinent
features will be located (with reference to known points on
existing maps) using a compass and 200 ft tape, if needed. This
site map will be used to locate and reproduce boreholes, sampling
points, and other pertinent features. The survey performed in
1988 by Channel Master may be used as a basis for the map.
Pertinent features for the site include facility dimension and
locations (e.g., buildings, tanks, piping), surface disposal
areas, fencing, and utility lines, roadways and railways,
drainage ditches, springs, surface water bodies, vegetation,
topography, residences, and commercial buildings. These should
be identified for possible contaminant migration and location of
potential receptors.

2.4.2 Planimetric Mapping
A map of the site that includes topographic information and
physical features on and near the site will be developed.
Existing aerial photographs will be used along with information
gathered during the preliminary site visit to identify physical
features of the area. The aerial photographs and property maps
for the site will be compiled. Scales sufficient to clearly show
site features and other important details will be adopted for the
mapping. Planimetric features that will be provided on this map
include paved surfaces, vegetation, fences, power poles,
walkways, structures, and all other obstructions. The site maps
will show all visually identifiable site features and contour
lines. Planimetric mapping will be produced from the most recent
aerial photographs available. Property lines will be drafted on
the planimetric map. The map will be used as bases for plotting
data collected under subsequent tasks.
2.4.3 surface Water Drainage Patterns
Drainage patterns within the site and vicinity will be identified
to determine potential routes of contaminant migration resulting
from surface water runoff and to identify locations where
sediments from this runoff may accumulate.
Drainage patterns will be identified from U.S.G.S. quadrangle
maps and the planimetric mapping. Additional rainfall
information will be obtained from the local weather bureau.
Additional data on soil characteristics will be obtained during
well drilling activities. Rainfall and soil data will be used in
the RI to predict the likelihood of future soil erosion. This
data will also be used in assessing the potential for future off-
site migration of contaminants.
2.4.4 Utilities Layout
Data from as-built drawings, municipal records, and previous
studies will be used in conjunction with information from local
utility companies to determine the location of underground tanks,
piping, sewer, and utility lines and to locate them on the
planimetric map for the site.
2.5 Sample Collection
The following subsections will describe the field screening,
surface water, sediment, surface/subsurface soil and groundwater
sampling investigations to be conducted during this RI. These
subsections will include the field equipment and supplies needed
and sampling procedures to be followed for each of the above
sample types. All provisions of the Channel Master Health and
Safety Plan (HSP) will be followed. Personnel will wear Level D
protective equipment as described in the HSP, with contingency

for Level C.
2.s.1 Field Screening
As described in the earlier sections, the Channel Master site is
potentially contaminated with heavy metals and voes. However,
the currently available information is not sufficient to define
the extent of contamination. An increasingly wide practice for
initial site characterization is to use on-site screening
methods. These methods provide the advantages of real-time
innovation and cost-reduction.
Hydrocone-type sampling, will be used with a portable GC as an
on-site preliminary screening tool for identifying voe
contamination in the groundwater beneath the site. This section
provides the field screening protocols to be followed.
The QA/QC protocols for all field related analyses will be
followed as per the EPA Region IV ESB SOPQAM (April, 1986),
"Quality Assurance for the Field Laboratory" (Hazardous Materials
Control Research Institute, 1987) and the respective
manufacturer's manuals.
2.s.1.1 Hydrocone-type sampling
The hydrocone-type technology is a rapid, economical means of
installing small diameter wells. This sampling instrument can be
pushed directly to the sampling depth, eliminating the need for a
drilled borehole. In this technology no drilling spoils are
generated, and the potential for crew exposure to contaminants is
greatly reduced.
To obtain a sample, a decontaminated, sealed sampler is pushed to
the required depth by a compatible cone rig. After reaching the
sampling depth, the porous sampler tip is exposed, and
groundwater sampling is initiated. Following sample collection,
the sample is secured by increasing the inert gas backpressure or
by using a similar method, and the sampler is returned to the
surface.
These hydrocone-type samples will be analyzed for the site-
specific voes, presented in Table 2-1, using a portable GC.
2.s.1.2 Hydrocone-type Sampling Locations
The proposed hydrocone-type groundwater sampling locations are
identified as shown in Figure 2-1. These 36 locations were
selected based upon the Channel Master site investigation
conducted during September 1986 (Soil and Material Engineers,
Inc., 1986; Industrial Environmental Analysts, Inc., 1988). This
investigation indicated that high concentrations of voes were
found in the area where the waste oil tanks were stored and where
13

voes had been spilled. Hydrocone-type sample locations were
chosen downgradient of the previously excavated areas at the
site, at the locations where voe contaminated soil was stockpiled
prior to treatment, and at the former sludge-drying area south of
the Bandag warehouse. Four additional off-site hydrocone-type
samples are also proposed for the drainage ditch east of the
site. These sampling locations are as shown on Figure 2-2. The
forty groundwater sampling locations are only tentative. They
will be modified depending on the site conditions and sampling
requirements.

The following equipment will be utilized for the hydrocone-type
sampling activities.
• Hydrocone-type samplers and compatible cone rig
• HNU 311 Portable Ge and related accessory equipment
2.5.1.4 Procedures
Hydrocone-type sampling procedures will be developed by the
successful bidder. These procedures will be in accordance with
the EPA Region III ESB SOPQAM (April, 1986) and include a section
on decontaminating the equipment. All procedures will be
submitted to Bechtel and approved prior to site mobilization.
The hydrocone-type sampler will not be moved to a new location
until satisfactory analytical results are obtained for any one
sample and will be decontaminated between each sample location.
sample Analysis
Volatile organics will be analyzed using an HNU 311 Portable Ge
calibrated with standards in the range of 1, 10, and 100 ppm.
The HNU 311 is a user-programmable photoionization detector (PID)
featuring an isothermal oven temperature range from 5-10° e above
ambient to 200° e, ppb sensitivity for many contaminants, and
variable selectivity based on choice of lamps. The portable,
self-contained unit includes the PID, carrier gas, calibration
gas, and a printer/plotter.
The HNU 311 Ge may be operated by generator or line power, and is
capable of continuous monitoring for all peaks of interest.
Programmed calibration mode and sampling methods are stored
indefinitely in a battery backed-up memory. Samples may be
introduced by an automatic gas sampling system, or by manual
injection through a heated injection port, allowing on-site
analyses of both gas and liquid samples. Data report output
includes retention times and concentrations. Variations in
concentrations are accommodated by an autoranging function.

These compounds have been selected based on their presence in
more than one soil sample and the water sample from the Channel
Master Monitoring well MW-5, and the ability to separate these
compounds using the on-site HNU 311 GC.
Calibration and Maintenance
Instrument calibration and preventative maintenance will be
performed in accordance with the procedures and schedules
recommended by the manufacturer. Instrument calibration and
maintenance activities will be documented in an instrument
logbook. Corrective maintenance will be performed as necessary.
The GC will be calibrated daily before field sampling operation
starts. Calibration will be achieved by using standards
traceable to National Institute of Standards and Technology.
Standards in the range of 1,10, and 100 ppm for the above
compounds will be used.
To calibrate the HNU 311 GC, the calibration standard sample is
either hooked to the calibration gas connection, or injected into
the injector port as appropriate. The latest calibration run
data is stored in the memory as long as power to the GC is kept
on. As soon as the unit is turned off, this data is erased from
memory; this eliminates the chance of using incorrect
calibration data at a later time.
Calibration checks will be run as a minimum of 5% of sample
analyses while in the field. If a calculated response factor is
greater than 30 percent difference from the previous response
factor, the GC will be recalibrated and the samples in question
rerun.
Quality Control
Bechtel will follow the guidelines for quality control specified
in the EPA Region IV ESB SOPQAM (April, 1986). The following

2.s.2.2 Procedures
The procedures outlined in this section will be adopted for
surface water sampling since Specific standard Field Methodology
for Surface Water Sampling referred to as Appendix F and Hin the
EPA Region IV ESB SOPQAM (April, 1986) have not been completed.
However, general precautions and instructions given in Section
4.6.3.2 of the EPA Region IV ESB SOPQAM (April, 1986) will be
followed as a general rule.
Surface water sampling involves submerging a glass bottle or
container into a water body and retrieving a sample. The sampler
will move to the sampling location by wading, taking care not to
disturb bottom sediments once reaching the sample location. In
a flowing stream, the sampler will approach the sampling location
from downstream and fill the bottle from upstream direction.
The procedure for surface water sampling is given below.
• When possible, collect sample from the bank of the water
body.
• Do not allow floating debris to enter the container.
• For volatile organic analysis, the appropriate amount of
acid preservative will be added to the sample containers
prior to collecting samples. Caution will be used to
prevent acid from washing out of the sample container during
collection. For all other samples requiring preservative,
the preservative will be added after sample collection.
• Tilt sample container on its side and allow to fill slowly.
• Replace cap .

pH/Temperature. pH and temperature will be measured using one
instrument with different probes, although separate instruments
could be used as well. The instrument will be calibrated in
accordance with the manufacturer's instructions at the beginning
of each work day. Measurements will be reported to the nearest
o.1•c for temperature, to the nearest 0.01 unit for pH. All
calibrations and measurements will be recorded in the field
logbook.
Specific Conductance. Increased concentration of dissolved
(ionic) species in a water medium is indicated by specific
conductance.
The specific conductance of the sample will be measured using a
self-contained conductivity meter. The instrument will be
calibrated in accordance with the manufacturer's instructions and
procedure at the beginning of each work day. Conductance will be
reported to the nearest ten units for readings under 1,000
umho/cm and to the nearest 100 units for readings over 1,000
umho/cm. Also temperature will be measured for correction of the
conductance value to 25•c. All calibrations and measurements
will be recorded in the field logbook.

2.5.3.3 Procedures
The procedure listed in this subsection will be adopted for
sediment sampling since "Specific Standard Field Methodology for
Sediment Sampling" (referred to as Appendix F and Hin the
Region IV ESB SOPQAM (April 1986) has not been completed.
However, general precautions and instructions given in Section
4.6.3.3.3 of the Region IV EPA SOPQAM will be followed as a
general rule.
• Sediment samples will be taken at the same four locations as
the surface water samples. They will be analyzed for the
parameters presented in Table 2-1.
• As described in section 2.6, sediment samples will be
retrieved from downstream locations to upstream locations.
Surface water samples will always be obtained prior to
sediment sampling at each location.
• Approach sampling station from a downstream point in order
to minimize bottom disturbance. If the bottom sediment is
accidentally disturbed, collect the sample at progressively
upstream locations, as required.
• Use a stainless steel spoon a stainless steel scoop attached
to the end of a telescoping stainless steel rod (depending
on the depth of the water) to scoop sediment sample from
stream bottom.
• Avoid collection of plant material and all material greater
than 1 cm in size. All care should be exercised to avoid
losing the fine materials which tend to disperse when
disturbed.
• Upon retrieving the sediment sample, do not remove water on
top of the final sample.
• Stake location and mark it on a site map for future
reference. Use landmarks or natural features as a future
reference point should stakes be destroyed.
• Photograph sampling activity while in progress.
• In field logbook record time, location, date, depth and
physical description of sediment sample. Also record serial
numbers and calibration dates of equipment used.

2.5.4 surface/Subsurface Soil Investigation
The surface and subsurface soil investigations are being
conducted to identify and to estimate the quantities of on-site
contaminants. This investigation is also focused to determine
both the physical characteristics of the overburden (for use in
contaminant transport modeling) and the off-site migration
potential.
Seven boreholes, each approximately 20 ft deep, will be installed
within the site at the proposed locations shown in Figure 2-3.
These biased sample locations have been identified based on the
activities around these locations. Soil samples will also be
collected from the boreholes where the proposed monitoring wells
will be installed. These monitoring wells will be approximately
50-60 ft deep each. The five proposed monitoring wells are shown
in Figure 2-4. Surface soil samples will be taken from the first
1 - 2 feet of each borehole. Subsurface split-spoon soil samples
will be collected from all the twelve boreholes at 5-ft
intervals, to a maximum depth of forty feet. All soil samples
will be analyzed for the parameters identified in Table 2-1.
2.5.4.1 Preparatory Activities
• The RPM will schedule CLP analyses through EPA.
• Bechtel will prepare IFB for drilling, select subcontractor.
• Bechtel will ensure all necessary equipment and sample
containers are properly cleaned prior to sampling.
• Bechtel will, when appropriate, locate and stake locations
before sampling begins.
2.5.4.2 Field Equipment
The Subcontractor will provide the following equipment to be
utilized for surface/subsurface soil sampling activities.
Drill rig
• Stainless steel split spoon samplers
• All other drilling required supplies and materials
2.5.4.3 Procedures
Revise the proposed locations of 12 boreholes based on
locations of utilities and on-site features subject to EPA
approval.
• Measure the borehole locations from the site survey and
estimate the borehole elevations from contour lines on the
topographic map.

• Pesticide grade isopropanol
• Alconox
• Distilled water
• Sample bottles
• Braided polypropylene rope
• Deionized, organic-free water
• Teflon bailer (if required)
2.s.s.2 Procedures
• Samples will be tested for those parameters presented in
Table 2-1.
• The water level in each well will be determined by direct
measurement using either a weighted stainless steel tape or
an electric sounding device.
• Once the depth to groundwater is established, the volume of
standing water in the well will be calculated via the
following equation:
V = 23.5(r2) X (d1 -d2)
where
V = volume of standing water in the well (gallons)
r = radius inside casing (feet)
d1 = total depth of the well (feet)
d2 = measured depth to groundwater from the top of the
inner casing (feet)
• All decontaminated equipment must be stored on clean
polyethylene sheeting and should not touch the ground
adjacent to the well. The pump and hose assembly will be
rinsed and allowed to air-dry after decontamination as per
EPA Region IV ESB SOPQAM (April, 1986).
• Lower the pump assembly to a depth which results in the pump
intake being located no less than one foot below the top of
the water table.
• Start pumping and record time. Lower the pump as needed to
maintain pumping near the top of the water table. Collect
purge water in labeled 55 gal. containers.
• Pump three to five casing volumes from the well.
Periodically check and record the pumping water level and
yield and make necessary adjustments. If the well is pumped
dry before 3 to 5 well volumes have been pumped, it will be
considered purged.
• A Teflon bailer may be used to purge the wells, depending on

the amount of purge water to be evacuated.
• Monitor temperature, pH, and specific conductance of the
pump discharge.
• once 3 to 5 casing volumes have been excavated, remove the
pump assembly from the well.
• Wearing a clean pair of chemical resistant gloves, remove
the bailer and check-valve from the wrapping and screw the
check-valve into the bottom of the bailer.
• Attach the dedicated polypropylene rope to bailer and pay
out enough line to submerge the bailer.
• Commencing with the first bailer, pour the bailer contents
into the VOA sample bottles. Use sample containers and
preservatives as specified in this section. Care must be
taken to ensure no air bubbles are included in the VOA
vials.
• Repeat the procedure for extractable organics, metals, and
cyanide samples, using the appropriate sample bottles for
each parameter. These bottles should only be filled to
where the bottles begin to taper inward.
• One sample will be collected from each of 10 existing
bedrock wells (municipal/residential), Samples will be
obtained from the spigot located closest to the pump. The
faucet will be opened to evacuate the contents of the
storage tank plus a minimum of three well volumes and any
filters will be removed before a sample is collected. The
number of samples collected may be revised on a residential
well canvas during the RI.
• Prepare a label for each sample indicating the location
number or identification number, sample number, depth of
collection, date/time, and analysis to be conducted. A
chain of custody control form and traffic reports will also
be prepared.
• Carefully package all sample bottles in their respective
coolers, add ice and vermiculite, and seal for shipment.
• Cap and lock the well.

2.6 Monitoring Well Installation/Development
The gradient and flow directions of the shallow groundwater
described for this site/site area are based on measurements made
over a relatively short period of time in a small number of
wells. The short time period does not permit accommodation of
annual precipitation cycles and their effect on the flow regime
at the site.
The methods Bechtel has selected to collect data to describe the
site geology in order to understand its relation to the
aquifer(s) and groundwater flow conditions include: geologic
logging, installation of monitoring wells, field hydrogeologic
testing, and examination and testing of geomedia samples.
2.6.1 Monitoring Wells
Five monitoring wells will be installed in the decomposed soil
zone above the bedrock. Decomposed bedrock is believed to be the
first stage of decomposition in this area, resulting in a
granular material similar to a sand. The final stages of
decomposition produce the clay-rich "saprolite" soil. This
saprolite and the bedrock beneath the site are believed to be
hydraulically connected and part of the same aquifer. The
existing upgradient well CM-1 will be sampled if possible. All
other wells that were installed previously by Channel Master have
been destroyed. The proposed locations of the five monitoring
wells and the location of CM-1 are shown in Figure 2-4. The
wells will be stainless steel and installed in accordance with
EPA Region IV ESB SOPQAM (April, 1986) Section 4.7.3. Detailed
procedures to be followed for installing the wells are discussed
in Section 2.6.2. Well installation and development activities
will be performed under the direct supervision of a Bechtel
geologist in the field.
The locations for the five new monitoring wells have been
selected based upon site information provided and observations
made during the site visit in November 1989. However, some of
the well locations may be adjusted in the field as field survey
and drill hole data are collected and more detailed subsurface
geologic information are available.
Four of the wells will be within the Channel Master site
boundaries, one well will be outside the site boundary. That
well will be placed on the railroad property near the discharge
of the cross-railroad culvert, assuming physical access is
possible and permission is obtained from the railroad
authorities.
All monitoring wells will be surveyed for location and elevation
and will be referenced to the North Carolina coordinate system.
This data, including well coordinates and elevations of the
29
I
I ground surface at each well and the top of riser casing with the
well cap removed, will be recorded in a bound logbook.

representative and least disturbed portion of the sample
will be bisected with a stainless steel knife. The center
of the core shall be incised, disturbing the sample as
minimally as possible, and the contents placed in and
completely filling an airtight sample bottle.
• All equipment will be steam cleaned prior to the
installation of each monitoring well. All sampling
equipment will be decontaminated as per EPA Region IV ESB
SOPQAM (April, 1986).
• Once reaching the desired depth, a 2" layer of silica sand
will be placed at the bottom of the hole.
• The pre-cleaned stainless steel well (including 10 ft, 0.010
slot size screen), will then be placed in the hole within
the hollow-stem augers. The augers will be slowly retracted
as the filter pack, and bentonite seal are being placed
around the well.
• A silica sand filter pack will be tremied into the annular
borehole space to approximately 2 ft above the screen.
• A 2-ft bentonite seal will be placed on top of the filter
pack. Bentonite pellets will be poured into the annular
space and tamped to prevent bridging.

• A cement bentonite grout will be installed to the surface.
The grout will be allowed to set for a minimum of 24 hr.
prior to installing the surface pad and protective casing.
• A stainless steel protective casing with locking cap will be
installed by pouring concrete on top of the grout. The
casing will be pushed a minimum of 2 ft into the concrete
ground.
• A formed concrete pad measuring 3 feet x 3 feet x 6 inches
will be placed at the surface. This surface pad will be
reinforced with a welded wire mesh and sloped to cause
drainage to flow away from the well.
2.6.4 Monitoring Well Development
All monitoring wells will be developed to improve the hydraulic
communication between the formation and monitoring wells and
assure the representativeness of groundwater samples. After
construction of the monitoring wells, each well will be developed
to remove fine-grained materials (silt, clay) from the gravel
pack surrounding the screen and maximize the ability of the
screened portion of the adjacent formation to produce water. A
variety of pumps, including the airlift, submersible, or hand
type or, alternatively, hand bailing, may be used to develop
wells. The site geologist will select the appropriate
development technology depending on the characteristics of the
well after construction. Wells will be considered developed once
the water has been cleared up. If the water does not clear, it
is likely to be due to the sediments in the bottom of the well.
In this case, the sediments will be allowed to settle for one
week and an air lift pump will be used to pump the sediments out
of the bottom of the well.
2.6.4.1 Health and Safety Guidelines
Both an HNU and OVA will be used to monitor the breathing zone.
Personnel will wear Level D protective equipment as described in
the HSP with contingency to upgrade to Level C in the event that
volatile concentration is shown greater than 1 ppm on HNU.
Field Equipment
The following equipment will be utilized for groundwater sampling
activities.
• Electric water-level indicator
• Specific conductance meter
• Marsh funnel (optional)
• Plastic buckets (1-, 3-, and 5-gallon capacity)
• Key for well locks and site gate locks
• Submersible pump/air lift pump/hand pump/teflon bailer

• Bailers (Teflon)
• 100-ft. steel tape with plunker
• Stainless steel sash-chain
• Check valves (teflon)
• HNU
• OVA
2.6.4.2 Procedure
• All development equipment shall be steam cleaned prior to
use.
• Promptly following the installation of an observation well,
each well shall be developed by surging, compressed air,
interrupted overpumping, or other methods approved by the
contractor.
• If the well is pumped, the rate and drawdown will be
measured to determine pre-development specific capacity.
• Development water and pump test water will be collected on-
site in labeled 55 gal. drums.
• Specific conductance of the development discharge water will
be measured routinely to assess the progress of the well
development.
• At regular intervals during well development, the well will
again be pumped and the rate of drawdown will be measured to
assess improvements in specific capacity.
• Development of the observation wells will continue until the
wells conform to the technical specifications and monitoring
well construction criteria included in the Invitation for
Bid (IFB) for drillers. If the water has cleared before the
bailing of the well, the well will be considered developed.
• Prior to the completion of the project and after all the
wells have been installed and developed, the subcontractor
will pump each well at a constant rate as required in the
IFB to determine specific capacity and drawdown.
• If air lift is opted, a venturi-type air lift pump will be
used to rapidly remove water from the well together with any
suspended fines that have entered the screen. This is an
effective well development method. The method relies on
rapid movement of water through the filter pack/screen to
suspend fine particles with a surging action generated by
cycling the pump. Fines that have accumulated inside the
well sump below the screen are readily removed by this
method. The method is limited by the ability of the
formation/well to rapidly produce water.

• If hand pump is opted, a small diameter hand pump may be
used for well development. These pumps are relatively
insensitive to sediment loads in the water and are
relatively easy to decontaminate. However, the rate of
production of water is closely related to the strength of
the operator and to the depth of the well. The pump cannot
be used to surge the well, only to remove water so uneven
development may result.
Development of the monitoring wells will continue using a
hand bailer until the water is visibly clear or the
suspended solids content of the produced water is less than
5 mg/L of suspended solids as measured during maximum
production rates.
• Remove and decontaminate pumping and test equipment. Lock
each well upon completion of the test.
2.6.S Drawdown Tests on Monitoring Wells
The drawdown of each monitoring well during a 2-hour pumping
period will be measured during this task. If the well yield is
not sufficient to maintain a 2-hour pumping period, the pump rate
will be slowed to an acceptable rate to maintain pumping. This
pump rate will be determined at the beginning of the pump test.
2.6.S.1 Preparatory Activity
• Develop each well
• All intrusive field equipment will be decontaminated prior
to the sampling of each well. Decontamination will be
conducted according to the EPA Region IV ESB SOPQAM (April,
1986).
2.6.5.2 Health and Safety Guidelines
Personnel will wear Level D protective equipment as described in
the HSP. Prior to initiating any field activities, the field
team will review and discuss, in detail, the HSP. All monitoring
and protective equipment should be checked thoroughly at this
time.
Field Equipment
The following equipment will be utilized for monitoring well
development activities:
Stainless steel water-level measuring tape (100 _ft)
• Electric water-level indicator
• 5-gal capacity plastic bucket calibrated in one gallon
increments or calibrated 55-gal drums

• Stop watch
• Key to well locks
• Submersible pump (3/4 HP)/Air lift pump/teflon bailer
• Braided polypropylene rope
2.6.5.3 ,Procedures for PUmping
• The water level in each well will be determined by direct
measurement using an electric sounding device and recording
the depth to water in the field logbook.
• Assemble the pump and attach the discharge hose.
• Measure the depth to water and allow water to recover to a
static level. Use this static level measurement as the
original water level.
• Start generator and pump the well at a constant rate.
Collect purge water in a 55 gal. drum. Purge water will be
kept to a minimum. Discharge rate will be determined using
a stopwatch and calibrated bucket. The amount of time it
takes to fill the bucket will be recorded.
• Take water level measurements once every 30 sec for the
initial 10 min, once every minute for the next 10 min and
every 5 min after 20 min until an equilibrium has been
verified.
• Record both the time and drawdown in the field logbook for
each water level measurement.
• Plot the time vs. drawdown on semi-logarithmic graph paper.
The time (in minutes since the start of pumping) should be
plotted on the logarithmic scale and the drawdown (in feet)
plotted on the linear scale.
• When the pumping level stabilizes, calculate the well's
specific capacity by dividing the discharge rate (Q) by the
drawdown. If after two hours the pumping level has not
stabilized, estimate the 24 hour drawdown by extrapolating
the time-drawdown plot. Use the predicted drawdown to
calculate the well's specific capacity.
After 2 hours, stop pumping the well and take water level
measurements at the following intervals:
0, 2, 4, 8, 16, 30 sec
1, 2, 4, a, 16, 30 min
until the well has recovered to 90 percent of its static
level.

• Record recovery data in the field logbook and plot time vs.
drawdown on the semilog paper. Compare recovery and pump
data to verify that specific capacity calculation were
correct.
2.6.6 Field Permeability Tests (Slug Tests)
Field permeability tests will be performed to measure, record,
and evaluate rising and falling head data from each well.
2.6.6,1 Preparatory Activities
• Develop each well
• Calculate gravel pack porosity (where applicable)
• Decontaminate all intrusive equipment
2.6.6,2 Health and Safety
Personnel will wear Level D protective equipment as described in
the HSP.
2.6.6,3 Field Equipment
The following equipment will be utilized during the field
permeability test.
• Electronic water level indicator
• Pressure transducers (5 psi, 10 psi)
• Dedicated field logbook and semi-log graph paper
• Enviro-labs data logger Model DL-120-MCP or equivalent
• Cylindrical slug (solid), 3.5 in. O.D., 60 in. long
• Alconox detergent
• Deionized, organic-free water
• Scrub brush
• Disposable 3/8 in. cord
Pesticide grade isopropanol
2.6.6.4 Procedures
• Measure the water level in the well using the electronic
water-level indicator and record the data in the field log
book.
• Complete the system setup procedures by setting the internal
clock in the data logger, input transducer scale factors,
and selecting appropriate logging sequence for each well.
Lower transducer into well to a depth of a ft beneath static
water level to reduce the possibility of damage to the
transducer by the slug. Allow transducer to stabilize, and
record initial head reading in feet. Input the logging
sequence in preparation of slug test.

• Lower slug into well, stopping at a pre-determined depth
immediately above the static water.
• Instantaneously introduce the slug into the water so that
the entire slug is submersed, keeping the bottom of the slug
from touching the pressure transducer. Once the well has
recovered to 90 percent or greater of its original level,
store data in unit memory as falling head measurements.
• Reset the data logger to standby mode.
• Leaving the logging sequence the same as for the falling
head test, instantaneously remove the slug from the water.
Tie off cord and leave the slug in the well suspended above
the water surface.
• Once the well has recovered to 90 percent or greater of its
original level, store data in unit memory as rising head
measurement.
• output data in memory to a printer upon the completion of
the test at each well.
• Evaluate the data obtained in shallow monitoring wells and
calculate the hydraulic conductivity and transmissivity.
Hydraulic conductivity is a measure of the capacity of a porous
media to transmit water. Hydraulic conductivity will be
determined using a Slug Test. This test involves dropping a
weighted object of known volume into the bottom of the well. The
amount of time it takes the top of the water column to return to
its original height is recorded.

3.0 SAMPLE HANDLING/CHAIN OF CUSTODY
Sample handling and chain of custody procedures will be followed
in compliance with Region IV SOP. The sequential steps involved
in the sample handling and shipping are presented as follows.
3.1 sample Authorization
All samples collected for TCL analysis during the RI phase of the
Channel Master site will be analyzed via the EPA CLP Routine
Analytical Services (RAS). All sample analyses for geophysical
characteristics will be performed by pre-qualified
subcontractors. In addition, surface water, groundwater, soil
and sediment samples will require CLP Special Analytical Services
(SAS). All analytical requests (RAS and SAS) will be initiated
through the RPM.
The following information will be supplied by Bechtel to the RPM:
• Name of requester, affiliation, and telephone number
• Name and location of site to be sampled
• Number and matrix of samples to be collected
• Type of analyses required (i.e., organics, inorganics)
• cyanide analysis requirement (inorganics only)
• Schedule of sample collection and shipment date
A minimum of two weeks lead time is required for RAS sample
collection authorization. A minimum of three weeks lead time is
required for SAS sample collection authorization. At the time of
the request, based on the information from the RPM, the RSCC
informs the Sample Management Office (SMO), which in turn assigns
a sequential case number to each individual RAS sampling
activity. This case number will be recorded in the field logbook
because it will be used to reference the request through sampling
and analysis procedures.
When a case number is issued, a laboratory assignment will be
made by SMO. Any changes occurring in the sampling schedule
after this time must immediately be brought to the attention of
RPM and SMO. These changes may include, but are not limited to,
number of samples, shipping date, schedule adjustments, and
sampling cancellations.
3.2 Sample Documentation
Each sample submitted for analysis will be properly documented to
ensure timely, correct, and complete analysis for all parameters
requested and to support the use of analytical data in potential
enforcement actions. The following documentation will be
submitted:

r I
• Sample Traffic Report or SAS Packing List
• Chain-of-Custody Record
The Region IV SOP, Section 3, provides detailed information
sample control, field record, and document control. These
procedures will be followed in close accordance.
3.2.1 Sample Traffic Report
on
The Sample Traffic Report (TR) is a four-page carbonless form
printed with a unique sample identification number. One traffic
report and its preprinted identification number are assigned in
the field to each sample collected. A copy of the organic TR is
provided in Figures 3-1 and 3-2. A copy of the inorganic TR is
provided in Figures 3-3 and 3-4.
As shown in Figure 3-2 and 3-4, only the pink copy which is being
sent to the EPA/ESD office should describe the special handling
of sample. Column D (special handling) should not be filled in
any other copy.
The bottom two copies (white and yellow) of the TR are submitted
with the sample shipment to the laboratory. The top copy (blue)
is submitted to SMO and the second copy (pink) is retained in
EPA's project file. A copy of the TR is made and retained in
Bechtel's project file.
A strip of adhesive sample labels, each printed with the TR
sample number, comes attached to the TR. One numbered label is
affixed to each container making up the sample. In order to
protect the label from water and solvent attack, each label is
covered with clear waterproof tape. The sample labels, which
bear the TR identification number, permanently identify each
sample collected and link each sample component throughout the
analytical process.
3.2.2 Special Analytical services (SAS) Packing List
For an "All SAS" type of request, samplers utilize the SAS
packing list, a four-part carbonless form. The packing list
provides space to list up to 20 samples on one form. SAS samples
are numbered using the SAS number followed by a hyphen and
progressive numerical designation, starting with 1 (e.g., S00E-1,
S00E-2, S00E-3, etc.). If the sampling activity extends over
several days and more than one packing list is used, care must be
taken not to repeat sample numbers.

To provide a permanent record of each sample collected, the
sampler completes the packing list, recording the SAS number,
site name and location, sampling data, shipment data, analysis
laboratory, sampling office, sampler name and telephone number,
individual SAS sample numbers, sample description and analytical
parameters requested.
After completing the packing list, the sampler includes the
bottom two copies with the sample shipment to the analysis
laboratory. Following sample shipment, the sampler sends the top
copy to SMO. The second copy is the sampler's file copy. One
copy of the SAS Packing List will be provided to the RPM.
An SAS form is filled out as shown on Figure 3-5. Upon receipt
of samples, the analysis laboratory documents sample condition
and signs the packing list, returning a copy to SMO and keeping a
laboratory file copy. Copies of the laboratory-signed packing
lists are provided to the RSCC as part of the SAS data package.
3.2.3 Chain of Custody Record
The following custody documentation procedure is used in
conjunction with CLP sample documentation for all samples
processed through the CLP. To maintain a record of sample
collection, transfer between personnel, shipment, and receipt by
the laboratory, a Chain of Custody Record (Figure 3-6) is filled
out for each sample type after all TRs have been completed and
sample bottles have been packed for shipment. Each time the
samples are transferred to another custodian, signatures of the
person relinquishing the sample and receiving the sample, as well
as the time and date, should document the transfer. A sample is
considered to be in an individual's custody if the following
criteria are met:
•
•
it is in your possession or it is in your view after being
in your possession
it was in your possession and then locked up or transferred
to a designated secure area
Under this definition, the team member actually performing the
sampling is personally responsible for the care and custody of
the samples collected until they are transferred or dispatched
properly. To follow up, the sampling team leader reviews all
field activities to confirm that proper custody procedures were
followed during the field work.
The Chain of Custody Record is employed as physical evidence of
sample custody. Each time the samples are transferred to another
custodian, the party relinquishing and receiving the sample must
sign and date the record and time of transfer.

The top, original signature copy (white) of the Chain of Custody
Record will be signed by the individual preparing the shipment
and the white and pink copies are enclosed in a plastic bag (with
CLP sample documentation) and secured to the inside of the cooler
lid. A copy (yellow) of the custody record is retained for the
sampler's files. The pink copy is retained by the laboratory and
the white copy is returned to the sampler.
Shipping coolers are secured with fiber tape and custody seals
are placed across cooler openings. As long as custody forms are
sealed inside the sample cooler and custody seals remain intact,
commercial carriers are not required to sign off on the custody
form.
Whenever samples are split with an owner/operator or government
agency, a separate Chain of Custody Record and a "Receipt for
Samples" form should be prepared for those samples, indicating
with whom the samples are being split and sample tag serial
numbers from splits. A copy of the "Receipt for Samples" form is
enclosed as shown in Figure 3-7.
3.3 sample Bottle Procurement
Sample bottles used (see Figures 3-8 and 3-9) for sampling for
the Channel Master site will be procured from a separate
subcontractor such as I-Chem Research or Eagle Picher
Environmental Services. The sample containers/bottles obtained
from the subcontractor should be precleaned and QC-tested
according to prescribed procedures of EPA's CLP to ensure that no
contamination exists that might affect sample data results.
Clean empty bottles are shipped to users in protective cardboard
cartons. All the bottles are procured directly from
subcontractor.
3.4 Sample Handling, Packaging, and Shipping
Samples obtained at uncontrolled hazardous waste sites are
classified according to pollutant concentration. "Low level"
samples are generally dilute and are usually collected from areas
surrounding a spill or dump site (i.e., off-site samples from
soils, rivers, lakes, etc.). "Medium level" samples are
generally collected on site, in areas of moderate dilution by
normal environmental processes. Low and medium level designation
swill be made by the Bechtel field team in the field. "High
hazard" (HH) samples contain greater than 15 percent of any
individual chemical contaminant and generally include samples
collected from drums, tanks, lagoons, pits, waste piles, fresh
spills, etc. HH samples require special handling procedures
because of their potential toxicity or hazard. HH samples are
not anticipated to be collected during remedial investigation
activities for the Channel Master site.

3.4.1 Packaging
• Place volatile organic sample containers in waterproof
plastic bags.
Place extractable organic bottles and volatile organic
bottles in a metal cooler.
• Place ice in large ziplock plastic bags and place the bags
in a cooler so that ice is not in direct contact with sample
bottles.
• Pack noncombustible, absorbent vermiculite around bottles to
avoid sample breakage during transport.
• Complete Traffic Reports, Chain of Custody Records, and
other shipping/sample documentation including air bill
numbers. Seal documentation in a waterproof plastic bag and
place the bag inside the shipping container. Do not fill
out traffic reports for EPA/ESD samples.
• Close the container and seal it with fiber tape and custody
seals in such a manner that the custody seals would be
broken if the cooler were opened.
• If samples are determined to be of medium hazard, all sample
bottles will be placed in waterproof plastic bags and then
placed in a metal can (paint can). Vermiculite will be used
to secure the bottles within the metal can, and clips or
tape will be used to hold the can lid securely, tightly, and
permanently. One bottle is packed per can. The metal cans
will be labeled as the sample bottle is labeled and then
packed as above.
3.4.2 Marking/Labeling
Attach return address labels to the inside of the cooler in a
clearly visible location.
• The outside of the metal cooler must be marked "Flammable
Liquid, N.O.S." or "Flammable Solid, N.O.S." if medium-level
samples are collected. The outside of the cooler must be
marked "Environmental Samples" if the samples are designated
"Low-Level." No DOT marking or labeling is required for
low-level samples.
• The appropriate side of the container must be marked "This
End Up" and arrows placed accordingly.

3.4.3 Transportation
All samples collected at the Channel Master site may be
transported by Bechtel personnel in private vehicles. All
samples can be shipped by overnight delivery service, but only in
"cargo only" aircraft. A copy of the shipment form is enclosed
for reference (Figure 3-10).
3.5 Sample Shipment Coordination
To enable SMO to track the shipment of samples from the field to
the laboratory and ensure timely laboratory receipt of samples,
the Bechtel field team will notify SMO immediately following all
sample shipments to provide the following information:
Sampler name
• Case number
• Exact number(s) and type(s) of samples
• Laboratory ( s)
• Carrier and airbill number(s)
• Method of shipment (e.g., overnight, two-day)
• Date of shipment
• Any irregularities or anticipated problem with the samples,
including special handling instructions, or deviations from
established sampling procedures
• Status of the sampling project (e.g., final shipment, update
of future shipping schedule)
Sample shipments made after 5:00 p.m. Eastern Standard Time (EST)
will be called into SMO at the start of business the next day
(8:00 a.m. EST). SMO will be notified by 3:00 p.m. EST Friday
concerning information on sample shipments going out Friday
intended for Saturday delivery/pickup. CLP laboratories remain
open to receive or pick up Saturday shipments only upon advance
notification by SMO and only when shipment airbill numbers have
been provided to SMO by the sampler.
Any postponements or cancellations, changes in the number or type
of samples to be collected, or changes in shipping dates must be
communicated to SMO as soon as this information is known.
