1.0 Introduction
This work plan is submitted to develop design data for the
extraction and treatment proposed as the preferred remedial
alternative for the ground-water operable unit, to further
characterize the contamination source, and to evaluate and test
treatment technologies for remediation of the source materials.
The work is divided into the following segments.
o Pump Test
Conduct a pump test to estimate the aquifer's hydraulic
parameters for design of the proposed ground-water
extraction system and for use in the design of the
ground-water extraction treatment system.
o Ground-Water Treatability
Determine biodegrability of most contaminated ground
water, and evaluate the effectiveness of air stripping and
carbon adsorption to remove the residual organic
compounds.
o Materials Characterization Investigation
Further determination of the chemical and physical
characteristics of the material present in the glycol
recovery unit (GRU} sludge pits and adjacent areas.

o Materials Handling Investigation
Evaluate equipment and techniques for physically handling
the materials in the glycol recovery unit sludge pits,
burn pits and other contaminated source areas at the site.
o Soil/Sludge Treatment Technology Evaluation
Conduct laboratory and bench scale investigations to
evaluate the efficiency of the potentially viable
treatment technologies previously discussed in the
Feasibility Study Report.
2.0 Background Information
2.1 Ground Water
The RI performed at the site has shown that various levels of
ground-water contamination exist. The area in the vicinity of
the GRU and burn pits has shown the higher level of
contamination. The more highly contaminated water appears to be
limited to the area west of the emergency ponds in the
wastewater treatment plant area. Data from the monitor wells
located east of the wastewater treatment plant show much lower
to no contamination from the plant operations. Analysis of
ground-water samples near the source showed several organic
compounds including ketones, phthalates, and several
non-identified chemicals not on EPA's Hazardous Substance List
(HSL) and possibly some elevated levels of·inorganic compounds
such as chromium. Ground water in this area has a total organic

carbon (TOC) loading between 3000 and 5000 mg/1 (ppm) and a
specific conductance between 4500 and 5500 micromho/cm. Ground
water near the site periphery has sporadically shown some·
organic compounds, but has TOC values of less than 15 mg/1 and
has generally showed specific conductance values of less than
200 mg/1.
2.2 Source Material
Due to the uniqueness of the physical nature of the buried GRU
sludges, a better understanding of the physical properties and
handling characteristics is essential to making appropriate
remedial technology recommendations. In addition to the
material handling investigations, a further detailed chemical
characterization of the soil/sludge materials will be conducted
during this period. This investigation will provide information
with regard to the consistency, uniformity; and make-up of the
various materials present.
Based on the available data, the physical consistency of the GRU
sludges ranges from a toothpaste like material to a coarser
grained, reduced moisture type of material similar in nature and
physical appearance to common spackling compound when it starts
to become dry. Preliminary analytical results have shown the
material to have a Chemical oxygen Demand (cod) in excess of
1,000,000 mg/1. Ethylene glycol concentrations have been found
to range between zero and 390,000 mg/1. A single BTU value

analysis showed a value of between 3,900 and 5,000 BTUs per
pound.
2.3 Summary of Feasibility study
The FS concluded that the preferred alternative for ground-water
remediation would be extraction from two lines of pumping wells
with their discharge pumped to a conveniently located treatment
facility designed to treat the anticipated flow rate and water
quality. To provide design data for this system, information is
needed on the aquifer's hydraulic parameters and on water
quality. Data on the aquifer parameters will be provided from
pumping tests on wells located along the proposed alignments of
the extraction systems. These points will also be used for
collecting ground-water samples for treatability analysis.
To date no treatability investigations have been conducted. The
technologies were selected for further evaluation based on their
overall effectiveness, suitability, degree of treatment
provided, and implementability from literature documenting their
effectiveness at other sites. The various treatment
technologies retained for further evaluation during this
investigative phase were then divided into subgroups for ground
water and source materials. Within each subgroup a limited
number of alternatives were identified for study as listed
below:

3.1.1 Pump Test
Two pump tests will be conducted to estimate the aquifer's
hydraulic parameters, aid in design of the ground-water
extraction system, and provide samples for water quality
analysis and treatability studies.
These tests will be performed on 4-inch extraction wells
installed in locations to be incorporated into the remedial

action program. One well will become part of the interior
extraction system or the Tier II wells and will be located in
the waste management area near the K, V, and O wells. The
second well will become part of the exterior extraction system
or the Tier I wells. This well will be located near the eastern
property boundary between the FF and GG wells. Figure 5-1 from
the FS is reproduced here as Figure 1 and shows the approximate
locations of the pump test wells.
Three additional 2-inch PVC monitor wells will be installed in
the vicinity of the extraction well in the waste management
area, and five observation wells will be installed near the
exterior extraction well. These will supplement the existing
monitor wells in the vicinity of the extraction wells for
monitoring water levels during the pumping and recovery cycles
of the test.
The pump tests will be run separately on consecutive weeks. The
extraction wells will be equipped with an electrical submersible
pump, and the pumped water will be piped into the plant's
wastewater treatment system. The wells will be equipped with
pressure transducers for recording water levels. These
transducers transmit data to a central recording station for
storage. After completion of the tests, the data are
transferred electronically to a micro-computer for reduction and
evaluation. The pump tests are planned to be at least 72 hours

to stress the aquifer and provide a better estimate of long-term
pumping performance.
Samples will be collected from the pumping wells prior to pump
testing for selected HSL parameter analyses for treatment system
design. Additionally, samples will be taken periodically
through the test for pH and conductivity analysis. These
readings will be made on a JO-minute frequency for the first 6
hours, and every 2 hours thereafter.
The results of these pump tests will be used to estimate the
aquifer's hydraulic parameters. These hydraulic parameters will
be used in the design of the proposed extraction system.
Additionally, they will be used in setting up a pressure model
to simulate the effects of the proposed extraction system on
existing ground-water conditions. The model intended for use is
the McDonald and Harbaugh "Modular Three-Dimensional Finite
Difference Ground-Water Flow Model" (MODFLOW).
The data available from the water quality analysis will be used
to supplement the existing data from the monitor well system to
provide a first approximation of the influent quality to the
ground-water treatment systems. These data may be supplemented
with time to set up and calibrate the Knoikow and Bredehoeft
computer model of "Two-Dimensional Solute Transport and
Dispersion in Ground Water'' (M.O.C.).

3.1.2 Ground Water Treatment
A limited number of technologies will be investigated with
respect to the treatment of the discharges from the two tiers of
ground-water recovery wells. Present data indicate that
satisfactory treatment of the discharges from the perimeter
system should be obtained using air stripping followed by
activated carbon adsorption. The interior tier would use
biological treatment and air stripping along with carbon
adsorption. The reason for the difference in treatment schemes
is the higher concentration of organics being removed by the
interior tier of extraction wells. In both systems, the carbon
adsorption is provided as "safe-guard" for final treatment.
Initial evaluations of liquid biological technologies (PAC) and
activated carbon adsorption will include the running of
appropriate adsorption isotherms for the determination of the
proper carbon dosages. Isotherm determination in conjunction
with laboratory and possibly field scale evaluations will enable
a cost effective determination to be made regarding the
feasibility of carbon adsorption and carbon regeneration for a
full-sale operation.
Use of air stripping as treatment process is expected to handle
the concentrations of volatile and a portion of the
semi-volatile compounds that exist in the exterior tier of the
ground-water recovery systems. The activated carbon adsorption
system will function as a "safe guard" step in case some organic

compounds remain after the air stripping. Furthermore, carbon
adsorption has been shown to be particularly effective in
removing heavy metals such as those indicated by the
ground-water analysis from the site monitor wells. The carbon
from the carbon adsorption unit will be utilized on a throw away
basis until utilization quantities or breakthrough frequency
supports either on-site or off-site regeneration.
Since air stripping and activated carbon adsorption are
considered conventional and widely accepted treatment
technologies it is felt that laboratory or field investigations
will not be necessary to augment the present level of
knowledge. Determinations as to the feasibility and use will be
based on suppliers input, presently available literature and
experience, along with additional data generated in conjunction
with the ongoing characterization studies. However, a
treatability study will be performed for the biological
treatment system planned for ground water for the inner tier of
extraction wells.
3.2 Physical/Chemical Materials Characterization
Further evaluation and determination of the location, physical
characteristics, and chemical composition of the contamination
source materials will be provided by sampling the waste for:
o visual characterization and physical description
o chemical characterization through laboratory analyses

3.2.1 Sampling for visual characterization and physical
description
To further identify the location and physical characteristics
of the materials in the source area, approximately 106 borings
will be drilled and sampled on a 50-foot grid pattern (see
Figure 2). Close observation of the physical uniformity and
consistency of the samples will be made and recorded during
their collection. The data collected from these borings will be
used to calculate a better estimate of the volume, location and
diversity of the probable source materials. All samples
collected will be visually described and stored in appropriately
maintained core boxes for later examination until this phase of
the investigation has been completed.
In order to expedite drilling these borings, no decontamination
of the drilling equipment will be performed between borings.
These borings will be continuously sampled using procedures
similar to the standard penetration test. Each of the borings
will be considered completed when residual soils are
encountered. It is anticipated that the depth of these borings
will range from 5 feet to 15 feet, and an average depth of 10
feet is-used for estimating purposes. All borings will be
backfilled upon completion with cuttings from the borehole.

Consideration is being given to use of a Microtox TM analyzer
for screening representative samples taken from the boreholes
drilled for the visual characterization study. This test ..
measures the relative toxicity of a sample to luminescent
bacteria and would act as a guide for selection of samples for
detailed chemical characterization. A decision on use of this
tool will be made based on the manufacturer's verification that
it is applicable to the contaminant source present at the site.
If this decision is not available at the time of the site work,
representative samples will be collected in VOA bottles for
possible later analysis.
3.2.2 Sampling .for chemical characterization through
laboratory analysis
The data collected from the physical characterization sampling
will be used to identify the location of borings and/or test
pits to collect samples for laboratory analysis. The samples
will be obtained with a drill rig or a backhoe that is
decontaminated using the protocols used during the Remedial
Investigation.
Samples collected with a drill rig will be obtained by using a
Shelby tube or a split-spoon sampler. Backhoe samples will be
taken from the backhoe bucket after possible fall-in material
from the test pit walls has been carefully scraped away. All
excavations or borings will be backfilled upon completion with
cuttings from the hole.

It is anticipated that 20 samples will be collected for
laboratory chemical analysis. If the on-site observations of
the material samples show a greater diversity than expected,
additional samples analysis may be needed to adequately
characterize this material. To follow EPA protocols, which
require duplicate samples, equipment blanks and other QA/QC
requirements, approximately four extra samples will be analyzed
in addition to the 20 samples planned. To allow some
contingency in costing, 30 samples are budgeted.
Characterization of the samples will consist of measuring the
values for the following physical and chemical parameters.
These data will supplement the detailed physical descriptions
obtained during the sample collection phase of this
investigation.

3.3 Materials Handling Investigation
as determined during
Following the collection and evaluation of the boring samples, a
determination of the most representative soil/sludge
contaminated area will be made. After selection of the area,
additional investigations will be conducted to evaluate the
physical handling characteristics of the various materials
present. These evaluations will consist of exposing a 4-foot
square of the material by carefully stripping back the soil
cover until the source material is reached. After uncovering
the source material, various methods of handling the materials
will be evaluated. These methods will include pumping,
dredging, loader handling, and possibly other techniques that
appear viable. An important objective of the materials handling
investigation will be to develop a system which minimizes the
physical handling of the material involved.
The overall objective of the material handling investigation is
to determine the most efficient method of collecting and
transporting the material present in the source area.
Minimization of handling of the material is to reduce the
potential for surface contamination and personnel exposures
during the source removal operations. In addition, the effects

of pumping on the liquifiability and flow characteristics of the
soil/sludge material will be determined. Specific requirements
for the potential treatment technologies being considered-will
also be evaluated as part of the materials handling study.
The handling characteristics will be evaluated through both
on-site and laboratory scale testing. Samples sent off site for
evaluation will be done under the appropriate DOT and EPA
regulations regarding the transportation and packaging of such
materials.
3.4 Soil/Sludge Treatment Technology Evaluation
The treatment technologies identified as viable for remediation
of the soil/sludge by the FS report will be further investigated
in this phase of the project. The additional investigations
will consist of laboratory and possibly field evaluations of the
various technologies listed and discussed below. A number of
technologies identified in the FS Report as potentially viable
treatment alternatives have been deleted from further
consideration at the present time due to either technological or
economic considerations. The methods retained for specific
evaluation are:

o combined physical/chemical and biological treatment
The technology evaluations during this phase of the
investigation will be done with regard to the individual
technology, and to combined treatment efficiency for the site
specific contaminants, their cost effectiveness, their overall
environmental reliability and safety, and their potential for
reduction of the contaminant volume, mobility and/or toxicity.
J.4.1 Thermal Destruction
The thermal destruction techniques being considered for
utilization in treating the soil/sludge contamination are:
o rotary kiln furnace
o fluidized bed furnace
o wet air oxidation
Evaluation will be done on a laboratory scale to demonstrate
their feasibility for handling the contaminant source. This may
be followed by larger field scale evaluations, if needed, once
the preferred technology has been identified. Larger scale
evaluations of any thermal destruction technology being
considered for use will be conducted only in the event that
sufficient scale-up, treatment efficiency, and reliability
evaluations cannot be adequately based on the smaller laboratory
scale information.

with their individual processes. Laboratory runs of sufficient
duration will be conducted to obtain the needed information.
Replicates of the runs will be conducted to assure the
reliability of the data generated and to evaluate whether
further investigations are needed.
Rotary kiln incineration will include the evaluation of both
single-stage and two-stage systems. In addition, the
alternative of pre-heating the soil/sludge material prior to its
introduction into a single-stage rotary kiln incinerator will be
evaluated as a substitute for the initial stage of a two-stage
system if material handling characteristics are acceptable for
such a system. The purpose of this evaluation will be to
determine the possible reduction in costs, if any, associated
with such a system modification. Since the primary function of
the initial stage of a two-stage system is for drying the
soil/sludge material, replacement of the first stage by
pre-heating would appear to have technical merit.
Evaluation of the fluidized bed incineration method of thermal
destruction will be conducted in a manner similar to that
utilized for the rotary kiln technique. Based on the laboratory
scale evaluation of the fluidized bed technique additional large
scale evaluations may be needed if this technology is selected.
The ability of the soil/sludge material to be distributed
throughout the fluidized bed, light and heavy fractions, the
volume and characteristics of the heavy and light fractioned

materials being released by the system, and the specific feed
characteristics required, may only be able to be adequately
determined through the utilization of a larger scale unit.· This
data, if required, would probably be obtained through use of an
existing fluidized bed installation as opposed to bringing a
larger or full-scale system on site.
The evaluation of wet air oxidation will be conducted initially
through use of laboratory-scale autoclave tests. Representative
samples of the soil/sludge materials will be subjected to
autoclave runs at low and intermediate temperature/pressure
ranges. Evaluations will be made to determine the potential for
autothermal operation of a full-scale unit, stability of the
resultant oxidized material, constituents of the processed
supernatent liquid, and their associated concentration levels.
3.4.2 Biological Treatment
Bioreclamation
The bioreclamation technologies evaluations will be performed on
laboratory and possibly larger equipment. The larger scale
evaluations will be of sufficient size to assure full-scale
scale-up problems have been addressed.
The composting technology investigation will initially be
conducted on a laboratory scale basis.using 55-gallon plastic
containers fitted with an appropriate aeration system.
Determinations will be made regarding bulking agent percentages,

type of bulking materials to be used, acceptable seeding
materials, treatment time durations, end products, and other
operational parameters. Following evaluation and optimization
of the composting technique on a laboratory basis, a larger
on-site field scale system may be evaluated. The utilization of
a larger field scale evaluation would enable determination of
site specific materials handling and mixing equipment. This
information would have a direct bearing on the final costs
associated with this alternative and probably would be performed
as part of the design study if this technology is selected.
If conducted, the larger scale field studies would be done on
site. Pilot compost piles utilizing the optimized conditions
determined during the laboratory study phase would be set-up on
the concrete slab at the existing decontamination area or in a
prepared portion of the north emergency pond. Typical pile
sizes would be in the range of 5 feet high by 10 feet long by 5
feet wide. Aeration would be supplied through a PVC header and
duct system fed by a conventional aeration blower.
Samples for laboratory .analysis will be collected and analyzed
on a bi-weekly basis to determine the degradation occurring in
the organic materials being treated. These analyses will
include routine field determinations of pH, temperature, oxygen
concentration, and moisture content. Other specific chemical
analyses will be conducted as needed during the study.

Along with the evaluation of the composting process on the
soil/sludge contamination, an evaluation will also be made
pertaining to the composting potential for treating the
contaminated stream sediments from the tributaries adjacent to
the site. This study will be similar to that described for the
source material.
Liquid Biological Treatment
A literature review and computer library search will be
conducted in conjunction with the bioreclamation evaluation.
These reviews will collect and evaluate previous work done on
specific-site contaminants to take advantage of existing
information and incorporate it into this study plan where
practical. The reviews will be conducted during the initial
phases of the characterization to incorporate their input into
the subsequent study.
Conventional liquid biological treatment methods, and PAC
treatment technologies may be evaluated utilizing laboratory
scale equipment capable of treating wastes at about a one liter
per minute flow rate. It is felt that the data generated from
such a system would be sufficient to determine the design
criteria required for full-scale use of the technologies.
Initially, and in conjunction with the characterization phase,
of the investigation, seven composite samples will be collected
from the soil/sludge contaminated areas and tested for
biological treatability using either Imhoff cones or Eckenfelder

reactors. The purpose of these investigations will be to
preliminarily determine the viability of biological treatment as
a remedial alternative.
3.4.3 Combined Physical/Chemical and Biological Treatment
Based on the results obtained from the biological treatment
evaluations, determinations will be made on the feasibility of
combining physical, chemical, and biological treatment
technologies. These evaluations will be made on the basis of
existing available technologies and their expected results. No
laboratory or field scale determinations will be conducted
unless they are needed for scale up.
