CLOSURE/POST CLOSURE PLAN
CENTRAL TRANSPORT, INC.
Ju1y 26, 1990
Charlotte, North Carolina Facility
INTRODUCTION
Central Transport, Inc. has been operating a bulk hauling
facility at Charlotte, North Carolina since 1972. Until the
late 1970 's, two lagoons were used to treat rinsewaters
generated in the cleaning of empty tank trucks. Use of the
lagoons was terminated in 1985 when a new on-site pretreatment
system commenced operation.
On May 30, 1990 1 Central Transport, Inc. and the State of
North Carolina, Department of Environment, Health and Natural
Resources, Division of Solid Waste Management, Hazardous Waste
Branch entered into an Administrative Order on Consent to
address certain conditions at the Charlotte site at 600
Melynda Road, in Mecklenburg County, North carol ina in a
manner consistent with State and Federal hazardous waste laws
and rules.
By entering into this order, CTI agreed to manage surface
impoundments (the waste management area) in accordance with
all closure, post-closure, ground water and financial

assurance requirements applicable to such units under North
Carolina Hazardous Waste Management Rules, and the Solid waste
Management Act.
This Plan has been prepared to describe the closure and
post closure monitoring of two surface impoundments (Lagoons
1 and 2, Figure 3). Closure, as described in Section F-1,
will consist of discharge of liquids in lagoons 1 and 2 to the
Charlotte-Mecklenburg Utility District, (permit number GOOS)
excavation of approximately 5200 cubic yards of sludge from
Lagoons 1 and 2, on-site stabilization of the lagoon sludges,
off-site disposal of the stabilized sludges as non-hazardous
waste and regrading of Lagoons 1 and 2. A third pond (Figure
3) will be regraded to allow free drainage. Pond 3 appears to
have been unintentionally created as a result of the
construction of Lagoon 1. Pond 3 will be regraded to restore
the area to its original topography .

truck rinsewaters. In 1972, the Charlotte terminal was
connected to the CMUO Sanitary Sewer system. Following this
connection, the lagoons served as a pretreatment system. In
the late 1970s, a pretreatment plant was constructed at the
terminal. The two lagoons served as a backup to the
pretreatment system. In 1985, two aboveground rinsewater
storage tanks and a new pretreatment plant were constructed.
Use of the lagoons was terminated in 1985 when the new
pretreatment system commenced operation.
Figure 3 is a site plan which shows the location of the
two on-site lagoons. Lagoon 1 was constructed with concrete
walls and with native clay materials on the bottom • Rinse
waters in Lagoon 1 were aerated using two floating aerators.
Lagoon 2 was an existing pond that had been constructed as a
farm pond prior to Central Transport•s purchase of the site,
according to available background information. Pond 3 shown
on Figure 3 appears to have resulted from construction of the
lagoons. An intermittent stream runs through the location of
Pond 3.
B-lb Regional Geology
The CTI site is located within the Piedmont physiographic
province of North Carolina, in the Charlotte Belt. The
massive crystalline and metamorphic rocks of the Piedmont are

covered by a layer of unconsolidated clayey to sandy material,
consisting of weathered parent rock and alluvium (Cederstrom,
1979) .
The underlying Charlotte Belt has been interpreted as a
tilted composite mass of intrusive igneous rock that has been
eroded (Wilson, 1983). The immediate vicinity of Charlotte is
underlain by a granite and diorite complex, which is
interfingered with a variety of local sedimentary and
metamorphic rocks (Legrand, 1952). Rocks in the Charlotte
Belt range in age from Paleozoic to Precambrian.
B-lc Regional Hydrogeology
The shallow ground water in the Charlotte area occurs in
the clayey to sandy soil as an unconsolidated water table
aquifer. The unconsolidated aquifer acts as a reservoir
which transmits water to the bedrock. The bedrock ground
water is contained in the joints, fractures, cleavage planes,
bedding planes, and solution channels in the rock (Legrand,
1952).
The flow of ground water within the unconfined aquifer is
dictated by topography; in other words, the surface of the
water table roughly mimics the land surface. Within the
bedrock aquifer, however, ground water flow is controlled by
the system of joints and fractures (Legrand, 1952) .

The soil boring locations were selected to provide a
preliminary assessment of the soil quality in the vicinity of
the lagoons. The five soil borings were advanced using the
hollow stem auger drilling method. The augers were advanced
until auger refusal indicated that bedrock had been
encountered.
Split spoon samples of the unconsolidated overburden were
collected continuously. The soil sampling method employed was
ASTM D-1586-84/Split Barrel Sampling, using a 2-inch outside
diameter split spoon sampler with a 140-pound hammer.
Following the collection of each soil sample, the split spoon
sampling barrel was decontaminated with soapy distilled water
followed by a nitric acid rinse, a methanol rinse, and a
distilled water rinse.
The head space in each soil sample jar was screened in
the field using a photoionization organic vapor detector (HNU
Model PI-101), in order to provide a preliminary indication of
the presence of volatile organic compounds within the soils.
Boring logs containing the field screening results and
detailed descriptions of the geologic materials encountered
during the drilling of each boring are included in Appendix B.
Based on the results of the head space screening and upon
visual observations, soil samples were selected for analysis.
Two samples were chosen per boring: the 2 to 4 foot depth
10

sample and the 6 to 8 foot depth sample. The samples were
from the unsaturated zone, above the water table.
The soil samples were analyzed for metals, voes,
base/neutral extractables, acid extractables, pesticides, and
PCBs. The analytical results are summarized in Table 2; for
metals, both a range and average of concentrations commonly
found in soils in the USA are also included. The reference
for the range and average of concentrations is the USEPA,
Office of Solid Waste and Emergency Response, Hazardous Waste
Land Treatment, SW-874 (April, 1983), page 273, Table 6.46.
Constituents which were not detected in the samples are not
included on Table 2 .
Oyerview -Soil Quality
A comprehensive discussion of the soil sample analytical
results is presented in the report entitled "Hydrogeologic
Investigation", which was submitted to the State of North
Carolina on June 20, 1990. A brief summary is presented in
this document. It should be noted at the outset of the
discussion that the analytical results provide a generally
positive assessment of site soil quality. While isolated
areas of soil contamination have been detected, the
contamination is relatively limited and does not appear to be

related to the lagoons. No consistent pattern of soil
contamination was evidenced by the analytical results.
Summary -Soil Quality
The following items represent the significant findings in
the soil analysis. Arsenic was detected in the MW3 2 to 4
foot depth sample at a concentration of 1615 ppm; the common
range is 1-50 ppm. The presence of arsenic can possibly be
attributed to naturally occurring minerals that may be present
in the soil. voes were detected in the MWl 6 to 8 foot depth
sample, and the MW3 6 to B foot depth sample, but were not
detected in other samples.

peristaltic pump with an in-line 0.45-micron filter.
A clean stainless steel bailer was used for sample
collection. Before each use, the bailer was washed with soapy
distilled water, followed by a nitric acid rinse, a methanol
rinse, and a distilled water rinse. At each well site, a new
piece of clear plastic sheeting was laid down around the well.
Clean equipment was placed on the plastic sheeting. A new
length of polypropylene rope was attached to the bailer. The
sampler put on a new pair of rubber gloves at each new well
site.
The sample jars were labeled and placed in a styrofoam
cooler with icepacks for shipment to the laboratory for
analysis. A trip blank and field blank were included for
quality control/quality assurance purposes. The trip blank
consisted of two 40-ml vials filled in the laboratory with
distilled, uncontaminated water. The trip blank was shipped
with empty sample bottles from the lab to the site, and with
full sample bottles from the site to the lab. The purpose of
the trip blank was to check if there had been contamination
during transport.
The field blank consisted of two 40-ml vials filled in
the field with distilled, uncontaminated water, using field
procedures identical to those procedures used during sample

Table 11 summarizes the results of this analysis .
Based on visual observations and physical and
chemical analyses, the addition of Portland Cement,
cement kiln dust or combinations of these materials
are viable remedial alternatives for the treatment
of sludge at CTI because they provide the highest
ranges of unconfined compression strengths and

This section is not applicable to the closure activities
planned for the surface impoundments.
F-2d Inspection Plan
Inspection of the former impoundment area will be made
quarterly by the Environmental Director of CTI, or his
qualified designee. The inspection will consist of a visual
review of the former impoundment area, fencing integrity, and
observations of unusual surface conditions or possible
indications of unusual subsurface conditions. In addition,
all groundwater monitoring wells will be inspected during
semi-annual sampling.
At the time of each inspection, a record will be made in
an inspection log, which is contained in Appendix G. Recorded
information includes: former surface impoundment
identification (Lagoon 1 and Lagoon 2), date and time of
inspection, item or issue inspected, notation of observations
made, and signature of inspector. Any problems observed

Chain of custody procedures are discussed in Work
Plan (Appendix E), under Ground Water Sampling and

F-2e(5ll Annual determination
The uppermost aquifer on the site is the bedrock
aquifer, as discussed under E-2. The annual
determination of flow direction will be based on
static ground water elevation measurements in all
the bedrock monitoring wells. Elevation
53
• July 27. 1990
measurements will be made in conjunction with
sampling rounds. Elevation measurements will be
made as described in the Work Plan, (Appendix E),
under Ground Water Sampling Protocol.
F-2eC5llCil Flow Direction
In each of the two on-site flow regimes, potential
flow direction will be perpendicular to contour
lines that will be drawn to represent equal ground
water elevations. The potential flow direction
will be toward lower ground water elevations. The
ground water elevation data will be tabulated in a
manner similar to Table 7, and will be plotted in a
manner similar to Figure 7.
F-2e(5l1Ciil Flow rate
In each of the two on-site flow regimes, the
hydraulic gradient will be derived from the contour
lines that will be drawn. Using the values for
hydraulic gradient, ground water flow velocities
will be calculated as described in the
Hydrogeologic Investigation Report.
54
•
I •
July 27, 1990
It should be noted that, of the three variables in
the velocity equation, the only one that can vary
with the passage of time is the hydraulic gradient.
On October 20, 1989, in-situ hydraulic conductivity
tests were performed on wells MW6 through MWll to
estimate the hydraulic conductivity (or
permeability) of the screened aquifer material.
The hydraulic conductivity was calculated by
measuring the rate of recovery of the water level
immediately following the development of each well.
The Hvorslev method was used to calculate the
hydraulic conductivities.
The in-situ hydraulic conductivity tests will not
be repeated each year.
Similarly, while varying ground water elevations
may result in varying ground water flow velocities
and in varying potential flow directions, the
hydraulic pathways (a joint or fracture) needed for
ground water flow in a fractured bedrock aquifer
will not vary with the passage of time. The
55
•
•
July 27, 1990
fracture trace analysis described in the Work Plan
and the Supplemental Report will not be repeated
each year.
F-2e(5lm Statistical Determination
Statistical procedures will be as discussed under
F-2e(5),
F-2e(5)n Results
It is estimated that laboratory results will be
received approximately 30 days after any given
sampling round. It is estimated that up to 30 days
will be required to perform the statistical
analysis, once laboratory results have been
received. Thus, an evaluation as to whether there
has been a statistically significant increase over
background values for each parameter monitored at
the compliance point wells will be available 60
days after the completion of any given sampling
round.
F-2f Maintenance Plan
Maintenance activities are not applicable to this closure
scheme, as no hazardous wastes or related structures will be
56
Jµly 27. 1990
located at the facility. The area of the former surface
impoundments, following removal of the solidified materials,
shall be regraded, and seeded. No special maintenance
activities need be designated, as there is no concern nor
hazard presented by the native earthen materials remaining
under the newly seeded areas. Reseeding, fertilization and
mowing will be performed as part of the facility's regular
landscaping care procedures.
F-2g Special Waste Management Plan
This section is not applicable to the CTI Charlotte
terminal, as the surface impoundments were not used to contain
chlorinated-dioxins, -dibenzofurans or -phenols.
F-2h Land treatment
The CTI facility does not operate a land treatment unit,
thus this section is not applicable to this closure plan.
f-2i Personnel Training
Inspection and routine procedures will be carried out by
qualified personnel (Environmental Director or his designee)
from CTI.
Ground water sampling will be performed by qualified
contracted personnel. Required training for contracted

personnel will depend on the activity performed. Only
appropriately trained and qualified personnel will be
contracted for the ground water sampling.
Employees involved with post-closure activities, such as
inspection and recordkeeping, will receive on-the-job training
specific to their job assignment. This training will be
performed by the Environmental Director, or contracted
personnel familiar with this project.
F-3 Notice to Local Land Authority
CTI will not have hazardous waste land disposal
activities at the Charlotte facility following the closure
activities. Therefore, this section is not applicable.
F-4 Notice in need
CTI will not have hazardous waste land disposal
activities at the Charlotte facility following the closure

F-6 Financial Assurance Mechanism 40 CFR 270.14lbl(15l, 10
NCAC lOF .0034{b)(5)
A letter of credit will be issued by the North Carolina
National Bank to CTI for 2.5 million dollars to cover both
closure and post closure costs. Both the letter of credit and
the standby trust agreement are being processed and will be
finalized imminently.
F-7 Post-closure cost Estimate
A Post-Closure cost estimate for CTI' s Charlotte, NC
facility is presented in Table 14. The total 3 year present
worth cost for post closure monitoring is $211,024. The value
presented is based on a present worth analysis of the annual
costs, assuming a 10% inflation factor over the three years of
the post-closure work.
All on-site post-closure work will be supervised and
performed by qualified CTI or contracted personnel. However,
the cost estimate has been prepared assuming all activities
are to be performed by contracted personnel, in accordance
with 40 CFR 264.144.
The Post-Closure cost estimate will be updated annually
to reflect the effects of inflation. This update will be made
within 60 days prior to the anniversary date of the
establishment of the financial instruments used as financial
59

assurance. This adjustment will be made using the inflation
factor from the most recent Implicit Price Deflator for the
Gross National Product, as published by United states
Department of Commerce.
The Post-Closure cost estimate will be adjusted within 30
days of a revision the Post-Closure plan, if such a revision
causes an increase in the cost of Post-Closure care. The
facility will maintain the latest Post-Closure cost estimate.
F-8 Financial Assurance Mechanism for Closure and Post-
closure Care
A letter of credit for $2.5 million from North Carolina
National Bank has been obtained by CTI for closure and post-
closure care. A letter of credit will be issued by the North
Carolina National Bank to CTI for 2.5 million dollars to cover
both closure and post closure costs. Both the letter of
credit and the standby trust agreement are being processed and
will be finalized imminently.
F-9 Liability Requirements 40 CFR 270.14(b) (17), 10 NCAC lOF
.0034(b) (5)
The liability requirements for sudden and nonsudden
accidental occurrences do not apply to CTl's lagoons. The
requirements, set forth at 40 CFR 265.147, are intended to
60

Stabilization Study

after the two days of curing. Free water was not present in
any of these samples and the samples could not be compressed
by applying hand pressure. Following three days of curing,
samples 2-1 1 2-2 1 2-3 and 5-2 exhibited these same properties.
The addition of quicklime to the sludge at all ratios
given J.n Attachment 1 resulted in significant releases of
heat, thereby rendering this approach unacceptable for use in
the field. Samples 5-2 and 5-3 exhibited temperature rises in
excess of 200 degrees Fahrenheit. A volume increase of 60
percent was also noted for sample 5-3, which would also tend
to preclude the use of quicklime for the stabilization method.
Unconfined compressive strength tests were conducted on
samples 1-3, 2-1, 2-2, and 2-3. Samples 5-2 and 5-3 were not
tested due to the significant release of heat during
stabilization testing. The results of the unconfined
compressed strength tests are shown on Table 2. The stress
strain diagrams are also included.
B. July 1990 Treatability Study
Experimental Procedure
The experimental procedure used in the July 1990
treatability study was similar to that used in the September
1988 treatability study. The stabilized sample was cured for
4 days before further physical (unconfined compression
strength) and chemical {TCLP) analyses were performed on the
sample .
D-3
U'Rf·\il:r~ ,:_.. CFl·•:[

Results
Following a four-day curing period no free water was
present in the samples. One sample was chosen for further
study. The sample that was selected was that which had 50%
(by weight) addition of Portland cement because its visual
appearance seemed to represent the results of the September
1988 treatability study wherein the Portland cement showed a
high unconfined compressive strength and a low percent volume
increase. TCLP and unconfined compression strength tests
were conducted on this stabilized sample.
Visual observation of samples which had been stabilized
with cement kiln dust and Portland cement indicate that the
use of other stabilization media will yield similar TCLP and
unconfined compression test results •
The results of TCLP tests conducted on untreated and
stabilized sludge are summarized on Table 11 of the closure
plan. Nearly all TCLP parameters were below detection limits
in both the "before" and "after" stabilization TCLP tests.
The primary constituent detected in the untreated sample TCLP
test was 2-methylphenol at a concentration of 400
microgram/ 1 i ter ( ug/ 1) . The post stabilization TCLP test
demonsrated that 2-methylphenol was reduced to 15 ug/l, a 96%
reduction in the leachability of 2-methylphenol.
An unconfined compression strength test was performed on
the stabilized sample. The results are shown on Table D-3.
The peak stress of 167 psi suggests that a smaller volume of
D-4
• Portland cement or cement kiln dust could be used as long as
TCLP requirements are met.
Conclusions
The September 1988 and July 1990 treatability studies
demonstrated that stabilization is a viable remedial
alternative for the treatment of the sludge at CTI because it
reduces the leachability potential to near detection limits
and provides unconfined strengths satisfactory for acceptance
at appropriately permitted landfills. Specification Section
02240 (Appendix F) sets forth criteria for acceptable
processes that may be considered.

WORK PLAN
SUPPLEMENTAL PHASE I HYDROGEOLOGIC INVESTIGATION
CENTRAL TRANSPORT, INC.
CHARLOTTE, NORTH CAROLINA
INTROQUCTION
O'Brien & Gere Engineers, Inc. has been retained by
Weinstein & Sturges, P.A., legal counsel to central Transport,
Inc. (CTI), to provide the hydrogeologic services necessary to
assess whether contamination has occurred in the ground water
near two lagoons located at the Charlotte, North Carolina
terminal site.
An initial hydrogeologic investigation has been conducted
by O'Brien & Gere. The investigation was outlined in the Work
Plan for the Ground water Monitoring Program, which was
included as an Appendix to the draft June 1989 Lagoon Closure
Plan. The results of the initial hydrogeologic investigation
are included in the May 1990 Report of the Hydrogeologic
Investigation.
In February 1990, the state of North Carolina provided
Weinstein & Sturges, CTI, and O'Brien & Gere with comments
regarding the above-mentioned Work Plan. The States's
comments resulted in a revised Work Plan for the Ground Water
Monitoring Program. The revisions to the Work Plan are
essentially clarifications of procedures; the revised Work
Plan is appended to the June, 1990 report.
The state's comments further resulted in this document,
the Draft work Plan for the supplemental Phase I Hydrogeologic
WP-1
OBRIEN S. GERE
•
Investigation. The purpose of this document is to outline
tasks that were not included in the above-mentioned Work Plan,
but that are required to fulfill the Administrative Order on
Consent, dated May 30, 1990 between central Transport, Inc.
and state of North Carolina, Division of Solid Waste,
Hazardous Waste Section. In summary, the purpose of this
Draft Work Plan is to outline a supplemental hydrogeologic
investigation that will, in combination with the investigation
already completed, fulfill the requirements of the Consent
Agreement.
Four supplemental tasks, as follows, will be completed:
1. Fracture Trace Analysis
2. Assessment of Potential for Vertical Ground
Water Flow
3. Ground water Sampling and Analysis
4. Report Preparation
SUPPLEMENTAL TASK 1: FRACTURE TRACE ANALYSIS
As discussed in Section 3.03 of the June 1990 report, in
a fractured bedrock aquifer, both a hydraulic pathway and
hydraulic potential are needed for ground water flow. While
ground water elevation data from the bedrock wells has been
used to assess the hydraulic potential, data has not been
collected regarding the hydraulic pathways.
Since ground water flow in bedrock is generally
controlled by fractures, a fracture trace analysis will be
WP-2
[J'BRIEN & GERE
•
•
conducted in order to provide data regarding the hydraulic
pathways. While subsurface features such as fractures cannot
be directly observed on photographs, surface features directly
influenced by fractures, such as stream channels and
geomorphic features, can be mapped.
In regions like the North Carolina Piedmont, where the
unconsolidated overburden consists of weathered, in-situ
remnants of the competent bedrock, the fractures are typically
reflected as linear areas of accelerated erosion. Erosion
controls topography and surface drainage patterns because
water flows through areas of least resistance. Therefore,
surface features such as drainage patterns and topography
typically reflect the underlying bedrock fracture patterns .
The fracture trace analysis will be based upon available
aerial photographs and upon the U.S. Geological Survey 7.5
Minute Quadrangle topographic map of the area. The
photographs will be analyzed first; then, the topographic map
will be analyzed, to confirm the patterns observed on the
photographs, and to reveal any fracture traces obscured on the
photographs by vegetation or cultural features. The fracture
trace analysis will be verified in the field to the greatest
extent practicable.
In the report, the fracture trace analysis will be
presented in two formats: first, a figure showing the traces

• overlaid on the topographic map will be provided; second, a
rose diagram representing the orientation of fractures will be
provided,
The data provided by the fracture trace analysis will be
used to either confirm or modify the generalized flow map for
the bedrock aquifer included in the June 1990 report.
SUPPLEMENTAL TASK 2: ASSESSMENT OF POTENTIAL FOR VERTICAL
GROUND WATER FLOW
In order to assess the potential for vertical ground
water flow on the site, one additional bedrock monitoring well
will be installed at the site. The well will be located
adjacent to bedrock monitoring well MW 11, so that a well nest
is formed. The additional monitoring well, to be designated
MW 12, will be deeper than MW 11. MW 11 was completed at a
depth of 27 feet below ground level. MW 12 will be completed
at a depth which is a minimum of approximately 50 feet deeper
than MW 11, in the first water bearing zone encountered at or
below the minimum depth. A zone will be considered to be
water bearing if it yields a minimum of approximately 1 gallon
per minute.
Regarding the state's requirements for three monitoring
wells to be located downgradient of the waste management area,
MW 11 is considered a downgradient well. The new MW 12 will
be considered a downgradient well. Given the difficult drill
rig access to the downgradient area (due to topography), the
WP-4

·•
"Standards of Construction -Wells Other Than Water Supply".
A well construction permit will be obtained from the State
prior to well installation.
Following installation of the well, the well will be
developed using compressed air or pumping methods in order to
clear fine-grained sediments from the well screen. water
generated from well development will be discharged to the
ground at the well site.
Equipment used for well installation that comes in
contact with potentially contaminated material will be
decontaminated with a high pressure steam clean wash. water
generated from equipment decontamination will be discharged to
the ground at the decontamination area.
A field survey will be conducted by a local surveyor to
determine the location and elevation of the well. Both the
ground surface elevation and top of PVC casing elevation will
be obtained for the well. The survey will be completed using
an established on-site bench mark.
An in-situ hydraulic conductivity test will be performed
on the well to estimate the hydraulic conductivity (or
permeability) of the screened aquifer material. The hydraulic
conductivity will be calculated by measuring the rate of
recovery of the water level immediately following the
development of the well. The Hvorslev method will be used to
calculate the hydraulic conductivity.
WP-6
O'BRIEN & GERI::
•
Static ground water elevations will be measured in all of
the monitoring wells on the site, including the new MW 12,
using an electric well probe. If measurements are taken in
conjunction with ground water sampling, they will be taken
prior to initiating ground water purging or sampling
procedures in any of the wells.
The static ground water elevations will be used to
evaluate horizontal ground water flow direction in the study
area. The comparison of static ground water elevations from
MW 11 and MW 12 will allow an assessment of whether there is
upward or downward vertical flow in the bedrock aquifer in the
vicinity of the MW 11/MW 12 well nest.
SUPPLEMENTAL TASK 3: GROUND WATER SAMPLING AND ANALYSIS
Two rounds of ground water samples were collected as part
of the initial hydrogeologic investigation. The sampling
results are included in the June 1990 Report of the
Hydrogeologic Investigation. The State's comments included
changes in O'Brien & Gere•s Ground water Sampling Protocol.
Specifically, changes in procedure for the filtering and
acidification of metals samples were required.
Futher ground water sampling is required in order to meet
the metals sampling requirements, to access the ground water
quality of the new MW 12, and to further assess the ground
water quality of the site .
WP-7
O'BRIEN & Gl::RE
•
One round of ground water samples will be collected from
the following wells: MW 1, MW 2, MW 6, MW 7, MW 8, MW 9, MW
10, MW 11, and the new MW 12. Ground water purging or
sampling procedures will not be initiated at MW 12 until a
minimum of 24 hours after its development.
Static ground water elevations will be measured in all of
the monitoring wells on the site, using an electric well
probe, prior to initiating ground water sampling or purging
procedures in any of the wells.
Ground water sampling procedures will be according to the
Ground Water Sampling Protocol included as Appendix B. The
protocol includes a sample Ground Water Sampling Field Log and
a sample Chain of custody Record. A description of sampling
procedures is also included here.
Before a well is sampled, the ground water elevation in
the well will be used to calculate the volume of water
standing in the well. Three times the well volume will be
removed from the well by pumping or by bailing with a clean,
stainless steel bailer so that the ground water sample is
representative of the water in the screened section of the
aquifer. The sampler will measure the temperature, pH,
specific conductance, and turbidity of the ground water sample
in the field.
Ground water samples will be collected with a clean,
stainless steel bailer. Before each use, the bailer will be
washed with soapy distilled water, followed by a nitric acid

rinse, a methanol rinse, and a distilled water rinse. At each
well site, a new piece of clear plastic sheeting will be laid
down around the well. Clean equipment will be placed on the
plastic sheeting. A new length of polypropylene rope will be
attached to the bailer. The sampler will put on a new pair of
rubber gloves at each new well site.
The sample jars will be labeled and placed in a styrofoam
cooler with icepacks for shipment to the laboratory for
analysis. A trip blank and field blank will be included for
quality control/quality assurance purposes. Chain-of-custody
documents for each sample will be initiated at the time of
sampling and will be maintained throughout the handling and
submission of the samples to the laboratory.
The ground water samples will be analyzed for the
following inorganic compounds:
1. Aluminum 13. Magnesium
2. Antimony 14. Manganese
3. Arsenic 15. Mercury
4. Barium 16. Nickel
5. Beryllium 17. Potassium

The ground water samples will also be analyzed for the
following EPA Priority Pollutants: Acid Extractables,
Base/Neutral Extractables, Pesticides/PCBs, and Volatile
Organic Compounds.
In addition, the ground water samples will be analyzed for
parameters listed in the North Carolina Administrative Code,
Title 151 Subchapter 2L -"Classifications and Water Quality
Standards Applicable to the Groundwaters of North Carolina",
Section . 0202 -11 Water Quality Standards", paragraph (g), that
are not included in any of the above lists or categories, with
the exception of dioxin, gross alpha particle activity,
radium-226 and radium-228. Based on previous chemical
analyses of samples from lagoon surface waters, lagoon
sludges, soil and ground water, there is no reason to suspect
the presence of the last four parameters in the ground water.
Dioxins are typically associated with the presence of PCBs,
which have not been previously detected on the site. No known
sources of radionuclides are, or have been, present on the
site.
A complete list of analytical parameters and methods is
included in the Ground Water Sampling Protocol.
rt should be noted that in addition to the unfiltered
inorganics analyses required by the state, O'Brien & Gere will

submit a set of filtered samples to the laboratory for
inorganics analyses. These samples will be filtered in the
field using a peristaltic pump with an in-line 0.45 micron
filter. This is reflected in the Ground Water Sampling
Protocol.
SUPPLEMENTAL TASK 4: REPORT PREPARATION
Following completion of Tasks 1 through 3 and receipt of
the analytical results, a report will be prepared. This
report will be considered to be a supplement to the June 1990
Report of the Hydrogeologic Investigation. The supplemental
report will summarize the field investigation procedures and
observations and present the data collected in the form of
drilling logs, tables, and figures. The data interpretation
and site assessment will be discussed. The following specific
information will be included:
results of the fracture trace analysis, as discussed
above;
an evaluation of the horizontal and vertical
directions of ground water flow; an updated ground
water contour map will be included if appropriate; a
flow net will be included if vertical flow potential
exists;
an evaluation of the ground water quality, in
tabulated and/or graphic form where appropriate; data
from the new well MW 12 will be included;

8. Pull the bailer out of the well keeping the
polypropylene rope on the plastic sheet or entirely
off the ground if it is too windy to place a
plastic sheet. The LEXANR bailer can be used to
observe the presence of any floating product layer
and the physical appearance of the ground water.
9. Record the physical appearance (color, odor,
turbidity, and presence of floating product) of the
ground water on the Ground water Field Sampling
Log.
10. If a floating product is observed, estimate its
volume and note this on the Ground Water Sampling
Field Log. The LEXANR bailer should be used to
collect a sample of any floating product layer into
40 ml vials for product identification. After this
sample is collected, or if no floating product is
found, proceed to the next step.
11. Attach the polypropylene rope to a clean, stainless
steel bailer, lower the bailer to the bottom of the
well, and agitate the bailer up and down to
resuspend any material settled in the well.
12. Initiate bailing the well from the well bottom
making certain to keep the polypropylene rope on
the plastic sheet. All ground water should be
poured from the bailer into a graduated pail to
measure the quantity of water removed from the
well.
13.
14.
continue bailing the well throughout the water
column and from the bottom until three (3) times
the volume of ground water in the well has been
removed, or until the well is bailed dry. If the
well is bailed dry, allow sufficient time for the
well to recover before proceeding with the next
step. Record this information on the Ground Water
sampling Field Log.
Remove the sampling bottles from their transport
containers, and prepare the bottles for receiving
samples. Inspect all labels to insure proper
sample identification. sample bottles should be
kept cool with their caps on until they are ready
