CLOSURE/POST CLOSURE PLAN
CENTRAL TRANSPORT, INC.
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 I 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, 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 .

.0034lb) IS)
Central Transport, Inc. (CTI) is a company which provides
bulk hauling services to a variety of industries. The Central
Transport, Inc., Charlotte, Ne terminal is located in the
northwestern section of the city of Charlotte, North Carolina.
The entire site consists of 30 acres, approximately 6 acres of
which are actively used for terminal operations. Lagoon 1,
Lagoon 2, and pond 3 cover approximately 1.25 acres. The
terminal operations began in 1969. The site had been farmed
prior to its purchase. The facility consists of a terminal
office, maintenance garage, truck washing bays, a boiler house
for steam production, a wastewater pretreatment system, former
waste treatment lagoons and parking facilities for empty tank
trucks.
Figure 1 is a topographic map of the area. There are
three houses, one mobile home and one church within 500 feet
from the surface impoundments. These structures are
upgradient of the lagoons and a public drinking water source
(CMUD) is available to them. The site is not within a 100
I••year flood plain (Figure 2). The nearest pUblic drinking

water supply is the Charlotte Reservoir which is approximately
1-1/2 miles northeast of the site. Based on the hydrogeologic
investigation (See report entitled "Hydrogeologic
Investigation, Central Transport, Inc." dated June 1990 by
O'Brien and Gere) , the reservoir is located upgradient of the
site. The site is in a sparsely populated area and is not in
close proximity to schools, health care facilities, prisons,
or designated historical sites. There are no continuous flow
surface water streams or wetlands on or near the solid waste
management unit.
B-la Waste Management History
Central Transport's Charlotte terminal includes
facilities for cleaning the inside of empty tank trucks
following delivery of bulk chemicals. Three cleaning
operations are used; selection of the cleaning method is
dependent upon the nature of the material which was hauled.
Some trucks are steam cleaned, others are cold water washed,
and another group is cleaned using a caustic wash operation.
Rinsewaters which are generated from these washing operations
are collected and treated prior to discharge to the Charlotte
Mecklenburg utility District (CMUD) treatment plant in
accordance with permit number 0188.
Historically, two on-site lagoons were used to treat tank

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).

B-ld site Geology
The maximum depth of the SUbsurface investigation for
this project was 52 feet. Therefore, the discussion of the
site geology will be limited to the uppermost 52 feet of
overburden and bedrock.
The unconsolidated overburden material at the site ranges
from 15 feet thick to 30 feet thick on the eastern side of the
lagoons, and from 3 feet thick to 21 feet thick on the western
side of the lagoons. The overburden consists predominantly of
silt and clay, with some sand occurring. Fill was encountered
in MW2, east of Lagoon 1 (Figure 3).
The overburden is underlain by blue-gray fine-grained
sandstone on the eastern side of the lagoons (MW6, 7, 8) and
by light-gray and green-gray siltstone on the western side of
the lagoons (MW9, 10, 11). While the encountered bedrock is
predominantly sandstone and siltstone, gray to green-gray
quartzite was also encountered, at the bottom of overburden
borings MW4 and MW5.
soil Geotechnical Characteristics
Two rounds of soil borings were performed; one on
september 8-12, 1988, and one on September 6-8, 1989. On
September 8-12, 1988, four borings were conducted to examine
subsurface materials and assess their geotechnical

oharaoteristios. Samples of the subsurfaoe materials were
collected using continuous split spoon sampling to the bottom
of each boring, approximately 25 feet. Using these samples,
each boring was logged to record variations within the
subsurface materials (Appendix B). Figure 4 presents
stratigraphic profiles for the site. Soil comprising the
saturated zone is a stiff olay formed fr~m the weathering of
parent rock material. Soils above the saturated zone are
dominated by high plasticity silts and clays.
Representative samples of the subsurface materials were
collected for further laboratory analyses. Samples were
collected wherever a significant ohange in the subsurface
materials was encountered. Seven samples were collected for
further study: two from Boring I, two from Boring 2, one from
Boring 3, and two from Boring 4. The percentage of fine
grained material passing the number 200 sieve, liquid limit,
and plasticity index of all seven samples were within the
North Carolina regulations for soil characteristics for
hazardous waste landfill liner construction. Summary results
for the soil laboratory analyses are presented in Table 1.
B-1f Soil Quality
Five soil borings, designated MWl through MW5, were
performed at the CTI site on September 6-8, 1989 (Figure 3) .

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 unoonsolidated 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 eaoh soil sample, the split spoon
sampling barrel was decontaminated with soapy distilled water
followed by a nitrio 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 deteotor (HNU
Model PI-lOll, 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 enoountered
during the drilling of each boring are included in Appendix B.
Based on the results of the head spaoe screening and upon
visual observations, soil samples were selected for analysis.
Two samples were ohosen per boring: the 2 to 4 foot depth

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, VOCs,
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.
Overview - 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. VQCS were detected in the MWl 6 to B foot depth
sample, and the MW3 6 to B foot depth sample, but were not
detected in other samples.

In order to comply with the intent of the Administrative
Order on Consent between CTI and the State of North Carolina
(executed May 30, 1990), CTI has agreed to manage the surface
impoundments "subject to all closure, post-closure, ground
water and financial assurance requirements applicable to such
units under North Carolina Hazardous Waste Management Rule,
and the Solid Waste Management Act". Based upon knOWledge of
operations at the facility and Chemical analysis, the sludge
is neither a listed waste (40 CFR 261.30 33) nor a
characteristic hazardous waste (40 CFR 261. 20 -24) under
either the "EP Toxicity" or "TCLP" tests. Tables 11 and 12
summarize these results.
In May of 1990, application for a Special Use Discharge
permit was made to the Charlotte-Mecklenburg Utility District.
(Permit G008 was received June 8, 1990 Appendix C). In
connection with this application, sampling and chemical
analysis of the lagoon discharge was conducted in November
1989 and February 1990. These results are presented on Table
3. A comparison of the lagoon water sample analyses to the

CMUD effluent limitations demonstrates that all parameters are
within the pretreatment standard. A March 1988 investigation
indicated no contamination in the surface water of Pond 3
(Figure 3).
In April of 1988, an investigation was conducted to
estimate the quantity and characterize the sediments in the
three surface impoundments. A summary of the estimated
quantities of liquid and sludge present in April 1988 is
presented in Table 4. Sludge samples were extracted using
Lexan'l> tUbing. Results of chemical analyses that were
performed on the April 1988 sludge samples are summarized in
Tables 5 (organics) and 6 (inorganics). Tables 5 and 6
include results for those compounds which were detected at
concentrations above the detection limit. Results have not
been included if the compound was not detected in the samples.
Approximately 1. 0 million gallons of water and 5,200 cubic
yards of sludge are contained in Lagoons land 2. The
chemical analyses of the sludge indicate that the compounds
that were present in the greatest concentration in Lagoons 1
and 2 were phthalates at concentrations ranging from 28 to
7.400 milligrams/kilogram (mg/kg. ppm). Phthalates were found
in the sediment from Pond 3 in concentrations ranging from 52
to 170 mg/kg. Trichloroethane, tetrachloroethene,
trichlorobenzene, and toluene were present in the sludges of

GROUNDWATER MONITORING
Introduction
A hydrogeologic investigation was conducted by O'Brien &
Gere Engineers, Inc. at the Central Transport, Inc. Charlotte
site. The scope of work and findings are reported in the June
1990 report of the Hydrogeologic Investigation. In June 1990
a Draft Work Plan for the Supplemental Phase I Hydrogeologic
Investigation ("Work Plan") was submitted.
The supplemental hydrogeologic investigation outlined in
the Work Plan (Appendix E) is underway. Upon completion, the
resUlts will be included in a Supplemental Report of the
Hydrogeologic Investigation ("Supplemental Report").
Three rounds of ground water samples have been collected
from the monitoring wells installed at the site. The first
two rounds were collected in October 1989 and November 1989,
as part of the initial hydrogeologic investigation. The third
round was collected in June 1990, as part of the supplemental
hydrogeologic investigation.
A fourth round of ground water samples will be collected
in September 1990. The sampling procedures and protocols,
including wells to be sampled and analytical parameters, will
be the same as included in the Work Plan (Appendix E) .

E-l Groundwater Monitoring Data
A total of nine ground water monitoring wells have been
installed by drillers retained by O'Brien and Gere at the
site. The scope of work, protocols and findings are described
in a report entitled "Report of Hydrogeologic Investigation"
dated June 1990 by O'Brien & Gere Engineers, Inc. Eight
wells, (installation date is shown in parenthesis) designated
MW 1 (9/6/89), MW 2 (9/6/89), MW 6 (10/02/89), MW 7
(10/03/89), MW 8 (10/03/89), MW 9 (10/19/89), MW 10
(10/19/89), and MW 11 (10/19/89), were installed as part of
the initial investigation. The location of these wells is
shown on Figure 3. One well, designated MW 12, was installed
in June 1990 as part of the supplemental investigation. The
approximate location of this well is shown on Figure 3. Its
exact location will be shown on a Figure that will be part of
the Supplemental Report.
The results of the hydrogeologic investigation indicate
wells MW 1, 2, 6, 7, 8, 9, and 10 are upgradient of the
disposal area. Wells MW 11 and 12 are downgradient of the
disposal area.
Three downgradient wells are required for post closure
monitoring under the terms of the consent order. As
previously discussed with representatives of the State of
North Carolina, difficult drill rig access to the downgradient
20
CfBRIEN [; Gem'
• JUly 26. 1990
area (due to topography) has prevented installation of a third
downgradient well. The third downgradient well will be
installed as part of the lagoon closure. The well will be
installed, developed, and sampled using protocols similar to
those described in the Work Plan (Appendix E). The
approximate location of MW13 is shown on Figure 3.
NOTE: The following information is a summary of the
information included in the Hydrogeologic Investigation Report
dated June 1990.
E-la Well Installation Procedures
The two overburden wells (MWl and MW2) were constructed
by lowering an assembly of two-inch inside diameter, flush
joint threaded, PVC well screen and riser casing into the
boreholes. The overburden wells were not developed following
installation, due to the small amount of water in the wells.
Table 7 summarizes the well specifications for each overburden
monitoring well. Appendix B contains boring logs for the
wells. The Supplemental Report will contain similar
information for MW 12.
In order to further evaluate local ground water flow
direction and quality, six bedrock monitoring wells,
designated MW6 through MW11, were installed on october 2-3 and
21
O'BRIEN I." GFh;
•
July 26. 1990
October 19, 1989 (Figure 3). The bedrock well installation
was completed using the air rotary drilling method, with a
nominal six-inch diameter bit. Drilling continued until a
depth ten feet below the water table was reached. Boring
logs containing detailed descriptions of the geologic
materials encountered during the drilling of each bedrock well
are included in Appendix B. The bedrock monitoring wells were
constructed using the same procedure as the overburden wells,
with the exception of MW7, Which was constructed as a flush
mounted well.
A field survey was conducted by General surveyors, Inc.
of Charlotte, North Carolina to determine the location and
elevation of each of the eight wells. Both ground surface
elevations and top of PVC casing elevations were obtained for
each well. Refer to Figure 3 for well location and elevation
data.
E-1b Site Ground Water Flow Conditions
The water table was encountered in the overburden (above
auger refusal) at only two of the five soil boring locations,
MW1 and MW2. Although the underlying bedrock aquifer is
recharged with ground water that has been transmitted through
the overburden, there is apparently insufficient recharge to
maintain a continuous saturated zone above the bedrock. The
22
CJ'Bf~l:=ry & GFRl:
•
•
Julv 26, 1990
data collected during the hydrogeologic investigation are
insufficient to draw conclusions regarding the degree of
hydraulic connection between the ground water encountered ~n
the overburden and the bedrock aquifer.
It should be noted that in a fractured bedrock aquifer,
both a hydraUlic pathway and hydraulic potential are needed
for ground water flow. A pathway can be a joint or fracture
in the bedrock, as described in section B-1 Geology.
Potential is indicated by ground water elevations, with
potential ground water flow from higher to lower elevations.
Data have been collected regarding potential, but not pathways
(ie, a fracture trace analysis has not been performed). A
fracture trace analysis is being conducted as described in the
Supplemental Work plan-Appendix E.
The results of the hydrogeologic investigation indicate
that two potential flow regimes exist on the site. The
potential ground water flow direction on the eastern side of
the lagoons (MW6,7,8) is to the south-southwest. The
potential ground water flow direction on the western side of
the lagoons (MW9,10,11) is to the east.
The topography of the site (Figure 1) suggests that the
two potential flow regimes may merge in a southerly direction
south of Lagoon 2. There is no significant difference in
23
O"RRIEN & G~:R~.
July 26, 1990
hydraulic conductivities between the two potential flow
regimes.
The results of the supplemental investigation will be
contained in the Supplemental Report. The Supplemental Report
will contain additional information regarding site ground
water flow conditions and ground water quality.
E-lc Ground water Sampling Procedures
Two rounds of ground water samples were collected. On
October 21-22, 1989, wells MW6, MW7, MW8, MW9, MW10, and MW11
were sampled. On November 14-15, 1989, the above set of wells
was sampled; in addition, MW1 and MW2 were sampled.
Before a well was sampled, the ground water elevation in
the well was measured. Then the volume of water standing in
the well was calculated. Three times the well volume was
removed from the well by bailing with a clean stainless steel
bailer, so that the ground water sample was representative of
the water in the screened section of the aquifer. The sampler
measured the temperature, pH, and specific conductance of the
ground water sample in the field. During the first round of
ground water sampling, the ground water samples collected for
metals analysis were filtered in the laboratory. During the
second round of sampling, the ground water samples collected
24
O'Bf1IEN [, GcW
JUly 26, 1990
for metals analysis were filtered in the field using a
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

July 26. 1990
The purpose of the field blank was to check if
there had been cross-contamination between sampling events
during the sample collection process.
Chain-of-custody documents for each sample were initiated
at the time of sampling and were maintained throughout the
handling and submission of the samples to the laboratory. The
samples were shipped to Martel Laboratories in Baltimore,
Maryland for analysis. Analysis was for metals, VOCs,

E-1d Overview - Ground Water ouality
A comprehensive discussion of the ground water sample
analytical results is included in the June 1990 Report of
HYdrogeologic Investigation. presented below is a summary.
It should be noted at the outset of the discussion that the
analytical results provide a generally positive assessment of
site ground water quality. with the exception of manganese,
no metals, base/neutral extractable compounds, acid
extractable compounds nor volatile organic compounds were
detected in MWll. While an isolated area of ground water
contamination has been detected at well MW7, the contamination
is relatively limited and dOes not appear to be related to the
lagoon.
The parameters detected in MW7 were phthalates, VOCs, and
phenols. Comparisons of the MW7 ground water results to both
the lagoon surface water results and the lagoon sludge results
indicate that neither Lagoon 1 nor Lagoon 2 appear to be the
source of the MW7 contamination.

E-1e Ground Water Ouality
On October 21-22, 1989, a round of ground water samples
was collected from wells MW6, MW7, MW8, MW9, MW10, and MW11.
On November 14-15, 1989, a second round of samples was
collected from the same wells. In addition, ground water
samples were collected from MW1 and MW2.
The samples were analyzed for total metals, Volatile
Organic Compounds, base/neutral extractables, acid
extractables, pesticides, and PCBs. The analytical results
are summarized in Table 8. Analytical parameters not detected
are not listed in Table 8.

summary - Ground Water Quality
Phthalates, VQCs, and phenols were detected in MW7 only.
Metals were detected in all of the ground water monitoring
wells, but, with the exception manganese and iron none were
detected at concentrations exceeding SDWA MDL I S or North
Carolina ground water quality standards. Furthermore, the
detection of metals in upgradient wells, as well as
downgradient wells (based on current ground water flow
potential data), is an indication that the metals may occur
naturally in the ground water.
B-2 Aquifer Identification
The hydrogeologic assessment of the site is included in
the Report. The Supplemental Report will contain additional
information regarding site ground water flow, as described in
the Work Plan (Appendix E).

• July 26, 1990
The uppermost aquifer at the site is considered to be the
bedrock aquifer, which is penetrated by wells MW 6, 7, 8, 9,
10, and 11. Ground water was encountered in the overburden at
only two of five soil boring locations, MW 1 and 2. Although
wells were installed at these two locations, ground water
occurrence in the overburden is neither continuous nor
correlatable. Therefore, the uppermost aquifer is considered
to be the bedrock aquifer. A more complete discussion of site
ground water flow conditions is given in Section E-l.
E-3 contaminant Plume Description
As discussed above under E-l, ground water quality data
collected during the October 1989 and November 1989 rounds of
sampling indicate that, no ground water contamination related
to the lagoons has been detected. Therefore, there is no
plume to be delineated.
E-4 Post-Closure Monitoring program
As discussed above in Section E-l, ground water quality
data collected during the October 1989, November 1989, and
June 1990, rounds of sampling indicate that, no ground water
contamination related to the lagoons has been detected.
Therefore, no hazardous constituents have entered the ground
water from a regulated unit.

fourth sampling rounds or by the Supplemental Report. The post
closure monitoring will be amended if necessary pending
receipt Of the analytical results.

F-lb(21b stabilization of Sludge
F-lb(21b(il Background
The slUdge will be stabilized to improve its
physical characteristics and reduce the
leachability potential of the slUdge.
Stabilization is a process by Which industrial
wastes are treated to bind hazardous constituents
and prevent dissolution of leachable materials and
release into the environment (Tittlebaum et al.,
1985) •
F-4
UBHIEN & GEAE
I.I
January", 1991
Cement based processes are commonly used in
stabilization. Cementitious processes add cement
and water (if not already present) to the waste.
Lime based or pozzolanic processes involve
siliceous and aluminosilicate materials, which do
not display cementing action alone, but form
cementitious substances when combined with lime or
cement. In both cement and pozzolanic processes
additives are sometimes combined with the
stabilization compounds to improve the
characteristics of the final product.
The primary mechanisms involved in the
stabilization process is microencapsulation.
Microencapsulation is a process in which the
contaminants are mechanically locked into the
stabilized matrix. contaminant loss is limited by
decreasing surface area exposed and isolating the
contaminants from environmental influences
(EPA/625/6-89/022). In addition to simple
encapsulation of the waste, chemical reactions
between the waste and stabilizing agent can also
study (Connors and L: 1990) leachability of•reduce the concentration of wastes. In a recent

January 4, 1991
several organics including bis(2-ethylhexyl)
phthalate was reduced up to a factor of 16 using a
cement based stabilization agent.
stabilization has been traditionally used for
inorganic wastes containing high levels of metals.
However, the use of stabilization in the treatment
of organic or complex mixtures of wastes has
increased. stabilization of organic Sludges or
complex mixtures (polyaromatic hydrocarbons, PCBs,
toluene, phthalates, aromatic chlorinated
hydrocarbons, VOC's) have been used at USEPA
"Superfund" sites (Selected USEPA Records of
Decision). Table 9 provides a listing of some of
the "Superfund" sites where stabilization of
slUdges containing organics was used.
Preliminary stabilization tests were performed on
the sludge to assess the effectiveness of both
cement-based and pozzolanic processes (Appendix D) .
Cement, fly ash, combinations of cement and fly
ash, hydrated lime and quicklime were tested.
SlUdge was mixed with stabilizing agents and
allowed to cure for three days. cement, fly ash
and combinations of thOSe two produced a stabilized

product with no free water and the highest range of
unconfined compressive strengths.
F-1bl21bliil Treatability Study
Treatability studies have been performed on the
sludge to assess the most effective method of
stabilizing the sludges, and thus rendering
potentially hazardous constituents immobile.
The test used a composite mixture of the sludge
from different areas of the lagoons. A TCLP test
was performed on a sample of the untreated sludge
to assess the basel ine toxicity of the sludge.
Table 11 indicates that the sludge leachability
prior to treatment is below current TCLP regulatory
limits.
The Sludge was weighed and placed into a plastic
cylinder. The stabilizing agent was weighed and
added to the sludge. During the mixing process
the temperature increase was recorded.
Following the curing period the volume increase and
sample properties of the stabilized sludge were
recorded. A Paint Filter test was performed to

O'BRIEN & GEF~E
•
•
January 4. 1991
determine the presence of free liquids.
Unconfined compression tests were performed
according to ASTM D 2166. stress and strain
measurements were recorded for each sample. A TCLP
test was performed on a sample that had been
stabilized using POrtland Cement to assess the
reduction in leachability provided by the process.
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
reduction in leachability potential to near
detection limits (Appendix D).
F-lbl2lbliiil On-site stabilization
Portland Cement and/or cement kiln dust, or an
approved equivalent, will be used on-site to
stabilize the sludges. The sludge will be mixed to

disposed of as non-hazardous waste in an appropriate
landfill. If for any reason contaminated sludge or soil
is stockpiled prior to treatment, it will be done in a
manner that will prevent a release to the environemt.
Roll-off boxes or any other suitable means may be used to
prevent a release. The recommended disposal cell will
meet the double-liner and leachate collection
requirements of a RCRA Subtitle C hazardous waste
landfill such as the GSX landfill in Pinewood, South
carolina.
F-1b(21e Backfilling Lagoon Areas
The contaminated sludge and soils will be removed and
disposed of off-site. Soil will be removed to
concentrations which meet acceptable soil clean-up
criteria. The areas formerly occupied by the lagoons
will be backfilled using suitable soil. No asphalt or
materials larger than two inches in diameter will be used
as backfill.
In order to demonstrate that no contaminated materials
will be used as backfill, the contractor will be required
to submit his source for fill for approval by the
engineer prior to beginning to backfill. If
documentation confirming that clean fill is being used is

not provided, the contractor will be required to take one
sample of fill per 50 cubic yards and analyze for
volatiles, acid/base/neutral extractables, and TCLP
metals and sUbmit the results for review by the engineer
prior to placement of the fill.
The following procedure will be used to backfill the
areas formerly occupied by the lagoons:
(1) The surface impoundment area will be graded (cut
and fill) with local materials to the desired final
elevations per final grade drawing (See Figure 5).
(2) Topsoil will be seeded to prevent erosion.

Visually contaminated soils from the bottom and
sides of Lagoons 1 and 2 will be removed to meet
acceptable soil clean-up criteria. Clean-up levels
will be based on site specific conditions,
including all constituents remaining in the soil at
the site. CTI reserves the right to submit a risk
assessment at a later date for review by a State

F-1bC2lfCiil Sampling and Testing Program
Samples will be collected from the sUbsoils and
lagoon sides to assess if residual contamination
exists (See Appendix F for sampling protocols).
Due to the homogeneity of the soils underneath the
lagoon, as evidenced by the consitency of materials
in the boring logs, a large number of soil samples
will not be required. Each lagoon will be divided
into four quadrants. One discrete sample will be
taken from the bottom and one discrete sample will
be taken from the side wall of each quadrant for a
total of eight samples per lagoon. During the
first verification round, samples will be analyzed
for the indicator parameters listed in Appendix F,
Section 02001 Soil Testing Protocol. Once the
excavated soil meets the established clean-up
criteria the soil will be sampled and analyzed for
all volatiles, acid/base/neutral extractables
including 2-chloroethyl vinyl ether, and TCLP
constituents. Excavated, contaminated soils will
be stabilized as necessary and disposed of off-site
in the same manner as the stabilized sludges.

Procedure
Excavation equipment, sampling equipment, tools,
and other equipment that may have come in contact
with contaminated materials will be decontaminated
in an area with an impermeable surface Which has
been approved by an independent professional
engineer. The decontamination pad will be
constructed in a manner that will prevent a release
to the environment. Decontamination will include a
tap rinse followed by steam or high pressure
cleaning to remove visible solids. Rinse waters
will be collected and discharged to CMUD in
accordance with the Special Use Discharge permit
Gooa (Appendix C). Prior to discharge, the rinse
water will be sampled in order to verify
decontamination. The equipment and structures will
be considered decontaminated when the
concentrations of all constituents are below the
detection limits recommended in sw-a46 or below
drinking water standards when they exist.
Disposable sampling equipment and protective
clothing will be containerized and disposed of in a
proper manner.

Chemical analyses of the surface waters and the sludges
of the lagoons are summarized on Tables 3,5, and 6. The class
of compounds that would serve as the best indicator compounds
are the VOCs and base/neutral extractables. VOC's are mobile
(ie, commonly found at the leading edge of contaminant
plumes), have low detection limits, and are not normally
present in ground water. phthalates, Which are base/neutral
compounds, are the most prevalent constituent found in the

with the passage of time is the hydraulic gradient.
On October 20, 1989, in-situ hydraulic conductivity
tests were performed on wells MW6 through MW11 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 .

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
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.

APPENDIX D
STABILIZATION STUDY
Introduction
On September 12, 1988, O'Brien & Gere Engineers, Inc.
received homogeneous sludge samples from Central Transport,
Incorporated (CTI). Stabilization tests were conducted on the
sludge to evaluate the effectiveness of both cement-based and
pozzolanic processes. The following stabilizing agents were
tested: cement, fly ash, cement and fly ash, hydrated lime
(Ca(OH)2), and quicklime (CaO). The cement utilized was
building grade Portland cement. The fly ash was obtained from
NY State Electric and Gas Company. The hydrated lime utilized
was commercial grade, and the quicklime was laboratory grade.
In order to demonstrate that stabilization of sludge from
Central Transport's facility would decrease the leachability
potential of organics, a second· treatability study was
performed comparing before and after TCLP results. On JUly 2,
1990, O'Brien and Gere Engineers, Inc collected a composited,
homogeneous sample of sludge from CTI. The stabilization
agents used in this study included cement, cement with fly
ash, and cement kiln dust (pozzalime). The pozzalime was
provided by JTM Industries of Marietta, Georgia •

September 1988 Treatability Study
Experimental Procedures
Three one gallon glass jars containing homogeneous
samples of sludge from CTI were received by O'Brien & Gere
Engineers, Inc. Upon receipt, the sludge in the three jars
was composited to form a single sample. The sample was of
uniform texture, resembling sand. Several large chunks of
material were also found in the sample.
The testing method consisted of mixing the sludge with an
appropriate quantity of each of the five stabilization agents
previously mentioned. The combinations investigated presented
in Attachment 1.
Each sludge aliquot to be tested was weighed and placed
into a plastic cylinder, 2.25" in diameter and 6.5" in height.
The stabilizing agent was weighed and added to the slUdge.
The combination was mixed for approximately five minutes to
provide complete mixing of the two materials. The mixture was
allowed to cure at room temperature for three days, with
observations of each sample taken after two days and three
days.
Results
Following the 48-hour curing period, the volume increase
of the sample and the sample properties were noted. Volume
increases for each of the fifteen samples are given in
Attachment 1. Samples 1-3 and 5-3 had stabilized completely

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, 2-2, 2-3 and 5-2 exhibited these same properties.
The addition of quicklime to the sludge at all ratios
given in 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
O'BRIEN & C.~EHl::
i.I
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/liter (ug/l). 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
O'BRIEN (, Gc.flF
------------_ _ _._ .
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 PLANSUPPLEMENTAL PHASE I HYDROGEOLOGIC INVESTIGATION
CENTRAL TRANSPORT, INC.CHARLOTTE, NORTH CAROLINA
INTRODUCTION
0' 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

but that are required to fulfill the Administrative Order on

and state of North Carolina, Division of Solid Waste,
• Investigation . The purpose of this document is to outline
Hazardous Waste section. In summary, the purpose of this
1-
2.
I • 3 •
4.
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:
Fracture Trace Analysis
Assessment of potential for Vertical Ground
Water Flow
Ground Water Sampling and Analysis
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
O'SRIEN & 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
WP-3
O'SRIEN /i. GERI'
•
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
O'SRIEN & GERE

third downgradient well will be installed as part of the
lagoon closure.
The well installation will be completed using the air
rotary drilling method, with a nominal six-inch diameter bit.
The drill cuttings will be inspected in the field for
lithology and moisture content. Once the desired depth has
been reached, the monitoring well will be constructed by
lowering an assembly of two-inch inside diameter, flush-joint
threaded, PVC well screen and riser casing into the borehole.
The well assembly will consist of 10 feet of PVC screen, with
0.020-inch slot size, attached to an appropriate length of
riser casing.
A clean sand pack will be installed in the annular space
between the well screen and the borehole. The sand pack will
extend two feet above the top of the well screen. A two-foot
thick bentonite seal will then be placed on top of the sand
pack. The remaining annular space between the borehOle wall
and the well casing will be filled with a cement grout. The
grout will extend to the ground surface, where a locking steel
protective casing with a cover will be installed. The
protective casing will extend approximately two to three feet
above the ground surface.
A typical well construction diagram is included in
Appendix A. The well construction will be in accordance with
the North Carolina Administrative Code, Title 15, Subchapter
2C "Well Construction Standards", Section .0108

"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 .

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 .

One round of ground water samples will be collected from
the following wells: MW 1, MW 2, MW 6, MW 7, MW S, 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 15, Subchapter 2L - "Classifications and Water Quality
Standards Applicable to the Groundwaters of North Carolina",
Section.0202 - "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.
It shoUld be noted that in addition to the unfiltered
inorganics analyses required by the state, O'Brien & Gere will

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 tiorizontal and vertical
directions of ground water flow; an updated ground
water contour map will be included if appropriate; a

GROUND WATER SAMPLING PROTOCOL
Ie GROUND WATER SAMPLING PROTOCOL
The following procedures will be used to obtain representativeground water samples. To obtain representative ground watersamples from wells containing only a few gallons of groundwater, the bailing procedure is preferred. TO obtainrepresentative ground water samples from wells containing morethan a few gallons, the pumping procedure generallyfacilitates more rapid sampling. Each of these procedures isexplained in detail below.
Sampling Procedures (BAILER)
1. Identify the well and record the location on theGround Water Sampling Field Log (copy attached).In order to minimize the potential for crosscontamination, wells will be sampled in order fromleast contaminated to most contaminated.
2. put on a new pair of disposable gloves.
3. Cut a slit in the center of a plastic sheet, andslip it over the well creating a clean surface ontowhich the sampling equipment can be positioned.

Using a clean electric well probe, measure thedepth to the water table and the total depth to thebottom of the well. Record this information in theGround Water Sampling Field Log. Depthmeasurements will be taken in all wells before thestart of any purging and sampling so that this datais collected over the shortest period possible.This will allow for less data variability due totime.
Clean the electric well depth probe by washing itwith a methanol rinse and a distilled water rinseafter each use.
Compute the volume of water in the well, and recordthis volume on the Ground Water Sampling Field Log.
Attach enough polypropylene rope to a clean, clear,LEXANR bailer to reach just below the surface of thewater table, and lower the bailer slowly into thewell making certain to sUbmerge it only far enoughto fill one-half full. The purpose of this is torecovery any oil film, if one is present on thewater table.

The LEXANR bailer should be used tocollect a sample of any floating product layer into40 ml vials for product identification. After thissample is collected, or if no floating product isfound, proceed to the next step.
11. Attach the polypropylene rope to a clean, stainlesssteel bailer, lower the bailer to the bottom of thewell, and agitate the bailer up and down toresuspend any material settled in the well.
12. Initiate bailing the well from the well bottommaking certain to keep the polypropylene rope onthe plastic sheet. All ground water should bepoured from the bailer into a graduated pail tomeasure the quantity of water removed from thewell.
13. Continue bailing the well throughout the watercolumn and from the bottom until three (3) timesthe volume of ground water in the well has beenremoved, or until the well is bailed dry. If thewell is bailed dry, allo~ sufficient time for thewell to recover before proceeding with the nextstep. Record this information on the Ground WaterSampling Field Log.
14. Remove the sampling bottles from their transportcontainers, and prepare the bottles for receivingsamples. Inspect all labels to insure propersample identification. Sample bottles should bekept cool with their caps on until they are readyto receive samples.

The downhole components 'of the WaTerra Pumpconsist of only a single tube Or pipe on the end ofwhich is a foot valve. The foot valve allows waterto enter the tube and prevents water from drainingback out of the tube.
The pump is operated by simply raising and lowering the tube repeatedly over a distance of a fewcentimeters using abrupt and rapid strokes. This isdone either manually, using the WaTerra leveredpump handle, or automatically, using the WaTerraPower Pump.
Like tossing a ballThe operating principle of the pump is best understood by the analogy of tossing a ball in the air. Jfyou hold a ball in your open hand and quickly raiseit then stop, the ball will continue to rise above yourhand due to its inertia until it stops due to the forceof gravity. In a similar way, by Quickly lifting andthen dropping the pump tubing, the column ofwater which is held by the foot valve, is "tossed up"inside the tubing.
-,
The manner in which water is lifted by the up anddown motion of the tube is further explained asfollows:
(I) When the pump is first installed in the well,thewater level inside the pump tubing will be the sameas the level in the well.
(2) By rapidly lifting the tube a distance of say 10em, the column of water inside the tube will alsomove up 10 em.
(3) At the end of this 10 Cm up-stroke, althoughthe tube stops moving, the column of watercontinues to move upwards inside the tube for ashort distance, say 8 em, due to its inertia. Simultaneously, an 8 cm long column of water is drawnthrough the foot valve.
(4) By pushing the tube down immediately after theup-stroke, an additional amount of water, say a 7em long column, is drawn into the tube due to theinertia of the water column with respect to the downmoving tubing. Therefore, for a single up and downstroke, the water level in the tube will have beenraised a total of IScm.
(S) By moving the tube up and down repeatedlyusing a sharp and rapid stroke to impart maximumupward momemtum to the column of water, thewater level inside the tube will quickly rise to thesurface and discharge out of the end of the tube.
When operated at a comfortable level of exertion,the WaTerra Hand Pump will deliver from 2 to over8 litres per minute for lifts of up to 40 metres.Higher lifts and flowrates are possible by usinglarger diameter rigid pipe and the WaTerra PowerPump mechanical drive.

How Does It Work?The WaTem Pump lilerally Iifls waler out ofIhe well using a single 5{8 inch O.D. flexibleplaslic lUbe filled wilh a fOOl valve on its boltOmend. To pump water, Ihe plastic tube is strokedup and down at a rate of over 90 strokes p"rminute. This is accomplished either manuallyusing the WaTe"" Hand Pump handle. orby motor, using the WaTerra Power Pumpdrive. The rapid up/down motion of the lUbeimparts upward momentum to the column ofwaler inside the tube, which causes the water toquickly rise to the surface and discharge OUI ofthe end of the lube.
High Flowrate and Lift CapacityAowrates from 2 to over 6 Litres per minute arepossible for lifts of over 30 metres.
Low Cost Dedicated PumpFor a typical multiple well site, the average costp"r dedicated pump is under 5;75 for polyetheJeneand 5300 for Teflon'.

NEW LOW-PRICED FOOT VALVENOW AVAILABLE
MODEL 0-25 AND 55-25
WaTerra Pumps Ltd. has developed a newsingle-piece Delrin foot valve which is asefficient as our earlier two-piece design butsubstantially lower priced and easier toinstall.
The Model 0-25 foot valve, shown full scalehere, is designed for use with 5/8 inch 0.0.plastic tubing (high density polyethelene isrecommended) .
To assemble, the foot valve is simply pushedand turned onto the end of a cleanly cutplastic tube. Because the foot valve ismade of Delrin, a very hard plastic, thethreads in the foot valve self-tap into theplastic tubing to provide a strong, watertight connection. NO special tools, effortor skill is required for assembly.
A stainless steel foot valve (55-25) isavailable for use with teflon tubing, or forsituations requiring a more durable pumpingsystem.
