FOREWORD
This report is a collection of abstracts summarizing 29 new case studies of site remediation applications
prepared primarily by federal agencies. The case studies, collected under the auspices of the Federal
Remediation Technologies Roundtable (Roundtable), were undertaken to document the results and
lessons learned from technology applications. They will help establish benchmark data on cost and
performance which should lead to greater confidence in the selection and use of cleanup technologies.
The Roundtable was created to exchange information on site remediation technologies, and to consider
cooperative efforts that could lead to a greater application of innovative technologies. Roundtable
member agencies, including the U.S. Environmental Protection Agency (EPA), U.S. Department of
Defense, and U.S. Department of Energy, expect to complete many site remediation projects in the near
future. These agencies recognize the importance of documenting the results of these efforts, and the
benefits to be realized from greater coordination.
The case study reports and abstracts are organized by technology, and cover a variety of in situ and ex
situ treatment technologies and some containment remedies. The case study reports and abstracts are
available on a CD-ROM, which contains a total of 342 remediation technology case studies (the 29 new
case studies and 313 previously-published case studies). Appendix A to this report identifies the specific
sites, technologies, contaminants, media, and year published for the 342 case studies.
Abstracts, Volume 7, covers a wide variety of technologies, including full-scale remediations and large-
scale field demonstrations of soil and groundwater treatment technologies. Additional abstract volumes
will be prepared as agencies prepare additional case studies.

INTRODUCTION
Increasing the cost effectiveness of site remediation is a national priority. The selection and use
of more cost-effective remedies requires better access to data on the performance and cost of
technologies used in the field. To make data more widely available, member agencies of the
Federal Remediation Technologies Roundtable (Roundtable) are working jointly to publish case
studies of full-scale remediation and demonstration-scale projects. At this time, the Roundtable
is publishing a CD-ROM (4th Edition), which contains a total of 342 remediation technology case
studies (29 new case studies and 313 previously-published case studies), primarily focused on
contaminated soil and groundwater cleanup.
The case studies were developed by the U.S. Environmental Protection Agency (EPA), the U.S.
Department of Defense (DoD), and the U.S. Department of Energy (DOE). They were prepared
based on recommended terminology and procedures agreed to by the agencies. These procedures
are summarized in the Guide to Documenting and Managing Cost and Performance Information
for Remediation Projects (EPA 542-B-98-007; October 1998).
By including a recommended reporting format, the Roundtable is working to standardize the
reporting of costs and performance to make data comparable across projects. In addition, the
Roundtable is working to capture information in case study reports that identify and describe the
primary factors that affect cost and performance of a given technology. Factors that may affect
project costs include economies of scale, concentration levels in contaminated media, required
cleanup levels, completion schedules, and matrix characteristics and operating conditions for the
technology.
The case studies and abstracts present available cost and performance information for full-scale
remediation efforts and several large-scale demonstration projects. They are meant to serve as
primary reference sources, and contain information on site background, contaminants and media
treated, technology, cost and performance, and points of contact for the technology application.
The case studies contain varying levels of detail, reflecting the differences in the availability of
data and information about the application.

-------
The case study abstracts in this volume describe a wide variety of ex situ and in situ soil
treatment technologies for both soil and groundwater. Contaminants treated included chlorinated
solvents; petroleum hydrocarbons and benzene, toluene, ethylbenzene, and xylenes; polycyclic
aromatic hydrocarbons; pesticides and herbicides; metals; and radioactive materials.
Table 1 provides summary information about the technology used, contaminants and media
treated, and project duration for the 29 technology applications in this volume. This table also
provides highlights about each application. Table 2 summarizes cost data, including information
about quantity of media treated and quantity of contaminant removed. In addition, Table 2
shows a calculated unit cost for some projects, and identifies key factors potentially affecting
technology cost. (The column showing the calculated unit costs for treatment provides a dollar
value per quantity of media treated and contaminant removed, as appropriate.) The cost data
presented in the table were taken directly from the case studies and have not been adjusted for
inflation to a common year basis. The costs should be assumed to be dollars for the time period
that the project was in progress (shown on Table 1 as project duration).
Appendix A to this report provides a summary of key information about all 342 remediation case
studies published to date by the Roundtable, including information about site name and location,
technology, media, contaminants, and year the project began. The appendix also identifies the
year that the case study was first published. All projects shown in Appendix A are full-scale
unless otherwise noted.

Contacts:
Varied by site
Technology:
Multi-phase extraction:
Multi-phase extraction was applied at Clotheshanger Cleaners and Former
Norge's Cleaners.
At Clotheshanger Cleaners, the treatment system consisted of eleven 4-inch
diameter recovery wells and one 2-inch diameter recovery well, installed to
depths of 10 to 60 ft bgs. The extracted soil vapors were treated using two
2,000-lb granular activated carbon adsorbers, and the groundwater was
treated using a low-profile air stripper.
At Former Norge's Cleaners, a DPE system was installed in addition to an
existing SVE system. It consisted of four groundwater extraction/SVE wells
in conjunction with two of the four existing SVE wells. The groundwater
extraction well design pumping rate was 5 gpm, and the extracted
groundwater was treated using a shallow tray air-stripper system. The tray
stripper was designed to reduce 3,000 \igfL influent PCE concentrations to
less than 3 \ig/L effluent concentrations.
SVE/Pump and Treat:
SVE/Pump and Treat was applied at Colonial Cleaners, Varsity Cleaners,
Stanton Cleaners, and Roxy Cleaners.
At Colonial Cleaners and Varsity Cleaners, ex situ SVE was performed. No
information was provided on the design of the system at Colonial Cleaners.
At Varsity Cleaners, 1,750 cy of soil contaminated with PCE were treated
using SVE. The recovered leachate was treated using air strippers and then
discharged to an exfiltration gallery. The pump and treat system was only
operated during the wet season. Extracted water was treated using two 200-
Ib granular activated carbon filters.
No information was provided on the design of the system at Stanton Cleaners.
At Roxy Cleaners, the SVE system was installed to remediate the on-site
source of contamination in the vadose zone. The pump and treat system was
designed with three groundwater extraction wells consisting of two on site
wells in the source area to exert hydraulic control, and one off site well in the
overburden to reduce mass and control groundwater migration.
Pump and Treat
Pump and Treat was applied at Sparta Laundry Basket. The system treated
extracted groundwater using granular activated carbon. The water was then
discharged to a nearby creek.

At four sites, the reported cleanup goals were the drinking water MCL for PCE or TCE. This was less than 0.003 mg/L
for Clotheshanger Cleaners and Varsity Cleaners, and less than 0.005 mg/L at Sparta Laundry Basket and Former
Norge's Cleaners.
At two sites (Clotheshanger Cleaners and Varsity Cleaners), the cleanup goal for DCE was the drinking water MCL
(0.07 mg/L).
At Colonial Cleaners, the cleanup goal for PCE was 5 \igfL.
Soil
At Clotheshanger Cleaners, the cleanup goal was a PCE leachability based on Cleanup Target Levels (CTLs)
(0.3 ng/kg).
At Former Norge's Cleaners, the cleanup goal for PCE was a Kansas Department of Health and Environment (KDHE)
RSK level of 180 ng/kg.
At Colonial Cleaners and Stanton Cleaners, the cleanup goal for soil was 1.4 mg/kg and 1.4 Hg/kg, respectively
At Varsity Cleaners, the cleanup goals were a PCE, TCE, and cis-l,2-DCE leachability standard of 30, 30, and
40 Hg/kg, respectively.
Results:
Groundwater
At Clotheshanger Cleaners, the MPE system pumped a total of approximately 26,000 gallons of water. The system
influent for groundwater at startup was 1,430 (ig/L PCE. During the latest quarterly sampling event in January 2003,
the MPE groundwater influent was 210 (ig/L PCE; groundwater concentrations in 3 wells were not substantially
changed over 2 years of operation.
At Colonial Cleaners, PCE, TCE, and 1,2-DCE concentrations 22 months after system startup were 98 \igfL, <3 \igfL,
and 23 ng/L, respectively. These concentrations indicate that the goal for TCE was met, but not for PCE or DCE.
At Varsity Cleaners, the maximum initial influent PCE concentration for the pump and treat system was 0.66 mg/L.
During the most recent operation period, the maximum influent PCE concentration was reduced to 0.44 mg/L,
indicating that the cleanup goal had not been met.
At Roxy Cleaners, the pump and treat system reduced levels of contamination by approximately 50% over a period of
three years. At the end of this period, the concentrations were still two orders of magnitude above the groundwater
standards.
At Sparta Laundry Basket, the pump and treat system treated approximately 47 million gallons of water. PCE
concentrations in water samples collected from one monitoring well dropped from 2.3 mg/L to 0.18 mg/L; TCE
concentrations were reduced from 0.023 mg/L to 0.015 mg/L; and 1,1,1-TCA concentrations were reduced from
0.019 mg/L to non-detect. These concentrations indicate that the cleanup goal for 1,1,1-TCA was met, but not the goals
for PCE or TCE.
At Former Norge's Cleaners, there was a 95% reduction of PCE in groundwater monitoring wells downgradient of the
remediation system. Some cross-gradient wells remained contaminated at original levels indicating the continued
presence of source area contamination. The SVE system removed more than 3,000 Ibs of VOCs. The shallow tray air
stripper reduced 3,300 (ig/L influent concentrations to less than 3 ng/L, removing more than 28 Ibs of VOCs from the
groundwater run through the tray stripper
Soil
At Colonial Cleaners, approximately 230 tons of contaminated soil was removed for ex situ treatment.
At Stanton Cleaners, the SVE system removed approximately 16,000 Ibs of PCE.
At Roxy Cleaners, the SVE system reduced vadose zone PCE contamination levels to 0.425 Hg/kg, meeting the
regulatory goal.

Electrical Resistive Heating at the Avery Dennison Site,
Waukegan, Illinois (continued)
Description:
The Avery Dennison site is located in the Waukegan-Gurnee Industrial Park in Waukegan, Illinois. From 1975 through
1992 film coating operations were performed at the site. Methylene chloride (MeCl) used in these operations was
unloaded in the northeast corner of the building, and transferred by underground piping to above-ground storage tanks in
the northwest corner of the building. In May 1985, an inventory check indicated that approximately 1,585 gallons of MeCl
was released from the underground pipe. Site investigations indicated that the released MeCl was present in the soil and
groundwater beneath the loading area, the bulk storage tank area, the underground transfer pipe, and a former stormwater
drainage system. Cleanup activities at the site performed from 1985 through 1998 included excavation, soil vapor
extraction, groundwater pump and treat, and air sparging. The results of additional investigations indicated that DNAPL
was present in soil at the site. ERH was used from December 1999 through November 2000 to address the DNAPL source
in the unsaturated zone.
The ERH system included 95 copper electrodes installed around the perimeter of 20 treatment cells, including six
electrodes installed below an active street, and sixteen installed inside the existing building. Thirty four recovery wells
were installed to extract of soil vapor and steam. Two thermocouples were installed in the center of each treatment cell, at
the shallowest (4 ft) and deepest (24 ft) levels of contamination. ERH was performed in the western portion of the
treatment zone starting in December 1999 and in the eastern portion of the treatment zone starting in June 2000. During
the first four weeks of operation, the system did not achieve the target heating rate and power input to the subsurface. The
vendor found that the electrodes had oxidized and that the down hole power cables had been damaged. System
modifications included installing galvanized steel pipes around the electrodes and using above-ground power cables. The
system was restarted and achieved the target heating rate and soil temperature, though the power input remained below the
design level. With the exception of four treatment cells, the concentrations of methylene chloride were reduced to below
cleanup goals by October 2000. Additional electrodes were added to these cells and the system was operated another
month to meet the cleanup goals. No cost data were available for this application.

Technology:
In situ conductive heating
Three free-standing trailers - a control trailer containing instrumentation, an
electrical substation providing power for the system (1 to 1.5 MW), and an
off gas vapor treatment trailer containing a flameless thermal oxidizer
Heater/vacuum wells (4.5 inches in diameter with sand packed liners in 6
inch augured holes) were operated at 1,400 - 1,600 ฐF; heat was injected into
the subsurface with soil gas extracted using a vacuum
Two areas treated - Area GP-31 (150 ft by 50 ft to a depth of 18 ft); Area GP-
28 (30 ft by 20 ft to a depth of 11 ft); Area GP-31-130 heater/vacuum wells
installed on 7.5 foot triangular spacing to a depth of 19 feet,with 25 of these
wells drilled through the concrete loading dock; Area GP-28 - 18
heater/vacuum wells installed on 7.5 foot triangular spacing to depths of 12
feet, with approximately 1 well per 50 square feet of surface area treated
Surface area between wells was covered by an impermeable silicone rubber
sheet to prevent fugitive emissions; thermally insulated mat was used to
minimize surface heat loss; 5 ft deep dewatering trench was installed
Maximum soil temperature in the treatment area at a depth of 13 ft - 212ฐF to
500ฐF
During operation, recharge of water in the wet till region prevented
temperatures in this area from rising above 212ฐF; however, all temperatures
in the area were at least as high as the boiling of water
Off-gases were treated with an 1800 scfm flameless thermal oxidizer with an
operating temperature range of 1800 - 1900ฐF
Type/Quantity of Media Treated:
Source zone (unsaturated)
Estimated area treated was 5,000 cubic yards or 6,500 tons of soil
Regulatory Requirements/Cleanup Goals:
The soil cleanup goals were 8 mg/kg for PCE, 25 mg/kg for TCE, and 0.080 mg/kg for 1,1-DCE
Cleanup goals were based on the Indiana Department of Environmental Management (IDEM) Tier II Clean-Up Goals

In Situ Conductive Heating at a Confidential Chemical Manufacturing Facility,
Portland, Indiana (continued)
Results:
Results of confirmatory sampling showed that concentrations of PCE and TCE in both areas were reduced to below the
cleanup goals; no data were provided for DCE
Prior to discontinuing heating, 50 soil samples were collected from the coldest locations (centroids) furthest from each
heater well and analyzed for VOCs; based on these results, along with data from temperature profiles and HC1
monitoring, heating was discontinued in December 1997
Confirmation sampling was conducted about six months later, after soil temperatures within the treatment area had
cooled to below 100ฐF.
Costs:
No cost data was provided for this application.
Description:
The 16 acre site is a chemical manufacturing facility located in the southern portion of Portland, Indiana, From 1937 to the
mid-1970's, the site was used for the manufacture of hard rubber products used in automobiles and then for the
manufacture of plastic exterior automobile parts and is currently being used for reworking automotive parts. Sampling
showed the presence of volatile organic compounds (VOCs) in in subsurface soils in two areas at the site that had been
used as loading docks. Area GP-31 was contaminated primarily with PCE and TCE; Area GP-28 was contaminated
primarily with DCE. VOCs were not found above the cleanup goals in groundwater.
In situ conductive heating was used from July to December 1997 to treat the unsaturated source zone in these two areas. A
total of 130 heater/vacuum wells were installed in the larger area (GP-31) and 18 in the smaller area (GP-28). These wells
were used to injected heat into the subsurface (1,400 - 1,600 ฐF) using the vacuum to extract soil gas. Off-gases were
treated with a flameless thermal oxidizer. Prior to discontinuing heating, about 50 soil samples were collected from the
coldest locations (centroids) furthest from each heater well and analyzed for VOCs. The results from the soil samples,
along with data from temperature profiles and HC1 monitoring, were used to determine whether additional heating was
required. Based on the results, heating was discontinued in December 1997. Before confirmation sampling was
conducted, soil temperatures were monitored for about 6 months as the soil within the treatment area cooled to below
100ฐF. Results of confirmation sampling showed that PCE and TCE concentrations were below the cleanup goals.

Dynamic Underground Stripping-Hydrous Pyrolysis Oxidation at the
Savannah River Site 321-M Solvent Storage Tank Area, Aiken, Georgia (continued)
Regulatory Requirements/Cleanup Goals:
The performance objectives for the pilot demonstration were: (1) contaminants must be extracted from the target
source zone; (2) the target source zone must be heated to the applied boiling point; and (3) air to support HPO must be
injected into the treatment area
The system must meet discharge limits for vapor emissions and water discharge; however, specific values were not
provided
Results:
From September 2000 through September 2000, a total of 31,000 kg of contaminant were removed (30,000 kg of PCE
and 1,000 kg of TCE)
By March 2001, more than 62% of the TCE mass had been removed compared to 26% of PCE mass; attributed to the
lower boiling point of TCE; after March 2001, concentrations and daily removal rates decreased more rapidly for TCE
than for PCE, likely due to removing the majority of TCE during initial heating and the relatively higher rate of
destruction of TCE by HPO
Performance objectives were met on March 8, 2001; however system operation was continued until September 26,
2001 for additional contaminant mass removal
The mass of contaminants destroyed in the subsurface by HPO was not quantified. However, based on estimates from
other projects and experimental work at Lawrence Livermore National Laboratory, the vendor indicated that the
amount of dissolved phase contaminants expected to be destroyed by HPO would be at least 10% (6,800 Ibs) and could
be as high as 30% (20,000 Ibs) of the contaminant removed by DUS.
Costs:
The Interstate Technology Regulatory Council (ITRC) reported a project cost of $29/cu yd for the pilot system not
including the cost for steam generation and treatment of vapor and dissolved phase contaminants
No additional information was provided
Description:
The Solvent Storage Tank Area (SSTA) is located west of Building 321M in the M-Area of the U.S. DOE Savannah River
Site (SRS), in Aiken, S.C. Building 321M operated as a target fabrication facility, primarily housing metallurgical and
mechanical processes such as casting, extrusion, hot-die-sizing and welding. The SSTA included a 17,000 gallon storage
tank for chlorinated solvents including PCE and TCE. Numerous spills and leaks were suspected to have occurred in this
area. Results of site investigations indicated that DNAPL was present in silts and clays in the vadose zone above the water
table at depths ranging from 20 to 35 feet bgs. A pilot-scale demonstration of DUS/HPO was performed from September
9, 2000 to September 28, 2001 to treat DNAPL in the source zone.
A treatment area of 100 ft by 100 ft by 160 ft (52,000 cubic yards) was used for the demonstration. The pilot-scale system
included 3 steam-injection well clusters installed around the perimeter of the treatment area; one dual-phase groundwater
and vapor extraction well installed in the center of the target zone; 3 vadose zone soil vapor extraction wells along the
perimeter of the target zone vapors; and vapor and effluent treatment. Air was injected into the deep saturated zone
injection wells to enhance the HPO process. Groundwater was heated to a temperature of approximately 100 ฐC, while the
source zone reached a temperature of approximately 100ฐC. By March 2001, the performance objectives for the pilot-scale
demonstration had been met. System operation was continued until September 26, 2001 to remove additional contaminant
mass. A total of 31,000 kg of contaminant were removed, including 30,000 kg of PCE and 1,000 kg of TCE. The reported
cost for the pilot-scale demonstration was $29/cu yd for the pilot system not including the cost for steam generation and
treatment of vapor and dissolved phase contaminants. According to the vendor, the most difficult region of the target zone
to heat was the shallow portions at the center of the treatment area. The most likely reason for this was the circulation of
air from the surface to the shallow zone. Restricting vapor extraction and continuous long-term steam injection sufficiently
heated this portion after five months of steam injection.

Technology:
In situ solidification/stabilization using Envirobond process
Envirobond is a combination of proprietary powder and solution developed
by Rocky Mountain Remediation Services, L.L.C. (RMRS)
Consists of a mixture of additives containing oxygen, nitrogen, and
phosphorus, with each additive having an affinity for a specific class of
metals
Forms metal complexes that immobilize toxic metals, preventing them from
leaching
Applied at 10 experimental units at a trailer park and one experimental unit at
an inactive pottery factory
Powder applied to surface of experimental unit using a fertilizer drop
spreader, and liquid applied over the powder using a watering can; powder
and liquid mixed into soil using a garden tiller
Flyash used to adjust soil pH of each experimental unit to approximately 7.0.
Thin layer distributed over surface of experimental unit and tilled into
experimental unit.
Type/Quantity of Media Treated:
Soil
Two areas treated - a trailer park and an inactive pottery facility
Units at trailer park measured 5 ft X 5 ft, and unit at pottery factory measured
3 ft wide X 6 ft long
Depth of demonstration in all units was limited to upper 6 inches of soil
Total volume of soil treated was approximately 5 cy
Regulatory Requirements/Cleanup Goals:
Reduce concentrations of leachable lead in soil to meet the RCRA/HSWA alternative universal treatment standards
(UTS) for lead in contaminated soil; this corresponds to a TCLP lead concentration no higher than one of the following:
1) 7.5 mg/L, or 2) 10 percent of the lead concentration in the TCLP extract from untreated soil.
Decrease soil lead bioaccessibility by 25 percent or more, as defined by the Simplified In Vitro Test Method for
Determining Soil Lead and Arsenic Bioaccessibility
30
-------
In Situ Solidification/Stabilization using the Envirobond Process at Two Sites in
the Crooksville/Roseville Pottery Area of Concern, Roseville, Ohio (continued)
Results:
Mean TCLP lead concentration at the inactive pottery factory was reduced from 382 mg/L to 1.4 mg/L - a reduction of
over 99 percent, meeting the alternative UTS for soil
TCLP lead concentrations in all treated and untreated soil samples from trailer park were either at or slightly higher
than the detection limit of 0.05 mg/L, and were not used to evaluate objective
Soil lead bioaccessibility at the trailer park was reduced by approximately 12.1 percent; soil lead bioaccessibility was
not evaluated at the pottery facility.
Costs:
The total cost for the demonstration was approximately $26,000, broken down into 12 separate categories. The unit
cost for the demonstration was $5,176 per cy.
These costs were used to estimate the cost for a typical application of Envirobond at full scale.
Full scale estimate was a site-specific total cost of $33,220, with a unit cost of $41.16 per cy for treating 807 cy of lead-
contaminated soil at a 1 -acre site within the CRPAC
Description:
The CRPAC is a former pottery manufacturing area located in eastern Ohio. Lead was used in the glazing step of the
pottery finishing process, and improper disposal of the lead-containing waste resulted in contamination of the upper portion
of soil in the area. A field demonstration of in situ solidification/stabilization using the Envirobond process was
performed at two sites (a trailer park and an inactive pottery facility) within the CRPAC in September 1998.
The demonstration involved applying Envirobond at 10 experimental units at the trailer park and one experimental unit at
the inactive pottery facility, treating a total of approximately 5 cy of soil. The two main goals of the demonstration were to
evaluate whether Envirobond could reduce concentrations of leachable lead in the soil to meet the alternative UTS and
whether it could decrease the portion of total lead in soil that is bioaccessible, as measured by the Simplified In Vitro Test
Method for Determining Soil Lead and Arsenic Bioaccessibility, by at least 25 percent. Data from the demonstration
indicated that the mean TCLP lead concentration at the inactive pottery factory was reduced from 382 mg/L to 1.4 mg/L,
which meets the standards. Data from the trailer park were not used to evaluate the goal because TCLP lead
concentrations in all treated and untreated soil samples from this location were either at or slightly higher than the detection
limit of 0.05 mg/L. Analysis of the data for the second goal showed that soil lead bioaccessibility had been reduced by
approximately 12.1 percent, which was less than the project goal of at least 25 percent.
The total cost for the demonstration was $26,000 and the projected total cost for use of this technology to treat 807 cy of
soil at full scale was $33,220, with a unit cost of $41.16 per cy.

ROD dated July, 1998.
Purpose/Significance of Application:
To reduce TCE concentrations in soil to below cleanup levels using the
Lasagna technology
Cleanup Type:
Full scale
Contaminants:
TCE
Waste Source:
Improper disposal of chemicals used as part
of cylinder integrity testing processes

Technology:
Lasagna
Uses an applied direct current electric field to drive contaminated soil-water,
in a process called electro-osmosis, through treatment zones installed in the
contaminated soil
Soil-water flows from the anode electrode toward the cathode electrode,
which is located in the center of the treatment zone
Treatment zones are vertical zones comprised of iron filings and Kaolin clay
(60% by weight iron particles in a 40% by weight Kaolin clay)
Treatment zone slurry was prepared off site and transported to Lasagna site
in a concrete mixer truck; slurry was injected using a hollow mandrel
Contaminants are broken down into nonhazardous components as they come
into contact with the iron particles in the treatment zone
Elevated soil temperature as a result of current flow through soil also
contributes to contaminant mobility and destruction
Type/Quantity of Media Treated:
Soil over a 6,480 ft2 area in Solid Waste Management Unit (SWMU) 91
Regulatory Requirements/Cleanup Goals:
Risk-based soil TCE cleanup level of 5.6 mg/kg, as specified in ROD
Results:
Average initial TCE concentration in soil was 84 mg/kg, with a maximum concentration greater than 1,500 mg/kg
After nine months of operation (August 2000), sampling data showed that average TCE concentration had been reduced
to 43.3 mg/kg, with a high of 552 mg/kg
After 21 months of operation (August 2001), average TCE concentration had been further reduced to less than
1.5 mg/kg, with a high of 27 mg/kg
Verification sampling in April-May 2002 (after system shutdown) indicated average TCE concentrations of 0.38 mg/kg,
with a high of 4.5 mg/kg, less than the cleanup goal of 5.6mg/kg
GC-MS analysis of select soil samples after system shutdown showed that cis-l,2-dichloroethene and vinyl chloride
were either absent or present at very low concentrations

Lasagna at the Paducah Gaseous Diffusion Plant Superfund Site, Solid Waste
Management Unit 91, Paducah, Kentucky (continued)
Costs:
Total cost for full-scale remediation was approximately $4,000,000, broken down as follows:
1999: Remedial design, remedial action work plan, mobilization and construction start: $2,510,000.
2000: Construction complete, post construction report, operations and maintenance plan and begin operations and
maintenance: $906,000 (this includes $785,000 for construction and $121,000 for operations and maintenance)
2001: Continue operations and maintenance, interim sampling report A: $263,000.
2002: Interim sampling report B, complete operations and maintenance period, verification sampling and analysis plan,
remedial action report: $279,000
There were no regulatory agency oversight costs associated with the project
Description:
SWMU 91 at the PGDP Superfund site in Paducah, Kentucky was used as part of cylinder integrity testing processes from
late 1964 until early 1965 and in February 1979. Before the cylinders were tested, they were chilled in a pit containing
TCE and dry ice. The TCE was not removed from the pit after the tests, eventually causing contamination of the
surrounding soil and groundwater. This report describes activities under one phase of the cleanup, which covered soil
contaminated with TCE. Full-scale operation of LasagnaTM began at the site in December 1999 under a Federal Facilities
Agreement, and continued for two years until December 2001.
The technology application involved inducing electro-osmosis in the soil using an applied direct current electric field. The
soil water was driven to treatment zones consisting of iron filings and Kaolin clay, where TCE was degraded to
nonhazardous compounds. The average initial soil concentration of TCE was 84 mg/kg, with a maximum concentration
greater than 1,500 mg/kg. The ROD specified a cleanup level of 5.6 mg/kg. After 21 months of operation, average TCE
concentrations had been reduced to less than 1.5 mg/kg, with a high of 27 mg/kg. Verification sampling after system
shutdown indicated average TCE concentrations of 0.38 mg/kg, with a high of 4.5 mg/kg, thereby meeting the cleanup
goal. The total cost for the remediation was approximately $4,000,000, including capital costs, construction, mobilization,
and operation and maintenance costs.
During the first two treatment zone installation attempts, the treatment material would not drop out of the mandrel as the
mandrel was vibrated out of the ground. It was determined that too many large particles existed in the iron aggregate
thereby impeding flow. To address this, the manufacturer re-supplied the treatment material with a smaller grain size to
address this. A cost-saving measure implemented during the project was monitoring the system remotely using a data
acquisition system, which also had shutdown capabilities for fault conditions.

In Situ Solidification/Stabilization at Koppers Co. (Charleston Plant) Ashley River
Superfund Site, South Carolina (continued)
Description:
The Koppers Co., Inc. Charleston Plant is located on 102 acres north of downtown Charleston, South Carolina. The site
includes part of the Ashley River that is used as a barge canal. Koppers operated the site as a wood-treating facility from
1940 to 1977, primarily treating raw lumber and utility poles with creosote, as well as pentachlorophenol and copper-
chromated-arsenate (CCA). The majority of wood-treating operations were conducted in the eastern portion of the site,
identified as the Former Treatment Area. Wastewater from these processes was discharged into a ditch. From 1978 to the
early 1980s, the site was used for storing wastes, including waste oil. The results of site investigations showed that
sediments at the site were contaminated with PAHs and DNAPL, including sediments in the Ashley River.
In situ solidification/stabilization was identified as the remedy for one acre in the active marine area of the river. Bench-
and pilot-scale testing were performed to develop a suitable grout and to assess the effectiveness of the remedy at full-
scale. Specially-designed equipment was used to solidify an estimated 2,450 cubic yards of sediment in the Ashley River,
extending from the riverbank into a channel about 25-ft deep. This included a "tubular injector" used for injecting and
mixing reagents, and a special amphibious "marsh excavator" used to inject and mix cement-based grout into the upper two
feet of sediment. According to the vendor, this type of equipment allowed grout to be injected at the required depths, and
made it possible to use solidified sediment as a platform to reach untreated sediment.

- feed system, rotary dryer, baghouse, thermal oxidizer, wet quench, and acid
gas scrubber
Stainless steel, direct-heated rotary kiln dryer approximately 40 ft long and
8.5 ft in diameter; 49 million BTU/hr propane-fired burner, and discharge
screw
Residence Time - 15 to 20 minutes; system throughput - 30 tons of soil/hr;
soil exit temperature - 725 ฐF to 750 ฐF; thermal oxidizer exit gas temperature
-> 1,810 ฐF
Contaminated soil screened with a PowerScreen Model Mark IV to remove
debris >2 in. long
Treated soil was moisturized and backfilled on site
Type/Quantity of Media Treated:
Soil/26,000 tons
Regulatory Requirements/Cleanup Goals:
Cleanup goals were established for 15 organochlorine pesticides as well as arsenic, lead, and mercury in soil
Goals for pesticides ranged from 0.0588 mg/kg for Aldrin to 400 mg/kg for Methoxychlor. The goal for DDT, one of
the most prevalent contaminants at the site, was 2.94 mg/kg
State's maximum acceptable source impact levels (ASILs) were identified for ground level air and stack emissions
Results:
Treated soil met the cleanup goals for the 15 organochlorine pesticides and the three metals
DDT concentrations were reduced to an average of 0.18 mg/kg
Initially the system did not meet the performance objectives for particulate air emissions, with the average particulate
concentration of 0.04 gr/dscf greater than the required 0.03 gr/dscf (corrected to 7% O2); the system was modified and
subsequently met all performance objectives

Thermal Desorption at Site B, Western United States (continued)
Costs:
The total cost for the LTTD application was $3,260,517, including $429,561 in capital cost and $2,830,956 in O&M
costs
The unit cost was $125 per ton, based on 26,000 tons of soil treated
Description:
Site B (actual site name and location confidential) in the western United States was used for formulation of pesticides from
1938 to 1985. Wastes from the formulation process and an on-site laboratory were discharged to a french drain/sump area
and to lagoons. Site characterization activities performed in 1986 showed elevated levels of pesticides in the soil,
including p,p'-DDD (ODD), p,p'-DDT (DDT), p,p'-DDE (DDE), hexachlorobenzene, toxaphene, bis(2-
ethylhexyl)phthalate, lead, and zinc. As part of a removal action conducted by EPA in 1993, soils were excavated and
thermal desorption was used to treat contaminated soil.
Thermal treatment system was performed from April to August 1995 using a low temperature thermal desorption (LTTD)
system owned by Williams Environmental Services, Inc. The LTTD system included included a feed system, rotary dryer,
baghouse, thermal oxidizer, wet quench, and acid gas scrubber. The rotary dryer was a stainless steel direct-heated rotary
kiln (40 ft long and 8.5 ft in diameter) fired by a 49 million BTU/hr propane-fired burner. Prior to treatment,
contaminated soil was screened to remove oversize material (> 2in.). A total of 26,000 tons of soil was treated with the
treated soil meeting the cleanup goals for the 15 pesticides and three metals of concern. Treated soil was moisturized and
use as backfill on site. The cost for this application was $3,260,517, including $429,561 in capital cost and $2,830,956 in
O&M costs for a unit cost of $125 per ton of soil treated.
Initially the system did not meet the objective set for particulate emissions, attributed to operational problems with the
demisters and scrubber. System modifications to address this problem included replacing the fabric mesh demisters in the
scrubber with stainless steel chevron demisters, increasing the critical velocity capacity of the demisters, and increasing the
blowdown rate from the scrubber to reduce the amount of salts being recycled in the scrubber water. The system met then
met its performance objective.

Technology:
Thermal Desorption (ex situ)
High vacuum, indirectly heated rotary retort that removes volatiles from non-
volatile matrices
Air and sweep gases eliminated from retort, minimizing gas exhausted to
atmosphere
Vacuum of at least 25 inches Hg and moderate temperature maintained
during operation
Heat indirectly applied within an insulated firebox fueled by natural gas,
diesel oil, or propane
Following drying phase, temperature raised to a target value, typically in the
range of 600-750ฐC, and held there for a predetermined period
Type/Quantity of Media Treated:
Mixed waste; 3,050 Ibs, consisting of soil and waste carcasses
Regulatory Requirements/Cleanup Goals:
Total mercury concentrations in residuals below 10 ppm
Universal treatment standards (UTS) of 0.025 mg/L leachable mercury as determined by TCLP tests
MACT standard of 40 (ig/m3 for mercury emissions
Results:
System treated mixed waste with a maximum mercury concentrations of 5,510 ppm.
Final residuals from the process had total mercury levels ranging from 0.55 to 8 ppm
Leachable mercury levels were 0.008 mg/L or less based on TCLP tests
Emission of mercury averaged between 1 and 14 (ig/m3 throughout system operation
Costs:
Based on the demonstration, the projected unit cost to treat waste at full-scale using the Sepradyne-Raduce system is
approximately $0.90 per Ib. This estimate is based on a processing rate of 1,000 Ib/hr, and assumes operation at full
capacity over 10 years. Capital costs are estimated to be $1,500,000. The unit cost includes disposal costs of the
associated waste streams (estimated to be $l,000/m3 for solids, $0.10/gal for wastewater, and $25/gal for organics), and
excludes decontamination and decommissioning costs.

Ex Situ Thermal Desorption using the SepraDyne-Raduce System at
Brookhaven National Laboratory (continued)
Description:
BNL is a DOE facility located in Upton, New York. The Laboratory conducted remedial excavation activities of the
Animal/Chemical Pits on site in 1997, generating mixed waste with elevated concentrations of mercury. A field
demonstration using the Sepradyne-Raduce system was conducted to evaluate the effectiveness of the system in
removing and recovering mercury from the mixed waste matrix.
The field demonstration involved treating 3,050 Ibs of mixed waste consisting primarily of soil and waste carcasses. The
goals of the demonstration were to reduce total mercury concentrations in the treatment residuals to below 10 ppm, reduce
leachable mercury concentrations to below 0.025 mg/L TCLP, and reduce air emissions of mercury to below 40 ng/m3.
Analysis of the data after the demonstration was complete showed that total mercury levels ranged from 0.55 to 8 ppm,
TCLP leachable mercury levels were 0.008 mg/L or less, and air emissions of mercury averaged between 1 and 14 (ig/m3
throughout operation of the system. These data indicated that the project goals and regulatory requirements were met. The
projected unit cost for treating mercury-containing mixed waste using the Sepradyne-Raduce system is $0.90 per Ib,
assuming a processing rate of 1,000 Ib/hr and full-scale operation over a period of 10 years. This cost includes disposal
costs and excludes decontamination and decommissioning costs. Data collected during the demonstration showed that the
process was able to provide a final product with a 23% weight reduction. Based on visual inspection, the volume reduction
was estimated at approximately 40 to 50%.

Thermal Desorption at Industrial Latex Superfund Site,
Wallington, New Jersey (continued)
Results:
Treated soil was placed into 250 cubic yard bins (260 stockpiles total) and one composite sample was collected from
each bin and analyzed for PCBs, S VOCs, and arsenic
Results showed that concentrations for PCBs, SVOCs, and arsenic in treated soil met the cleanup goals
16 of the 260 stockpiles of treated soil (approximately 6%) were retreated because they did not initially meet the
cleanup goals
Costs:
Actual costs for this application - $15,700,000, including capital and O&M costs
Unit cost of $292 per cubic yard, based on 53,685 cubic yards of soil treated
Description:
The 9.67 acre Industrial Latex Superfund Site, in Wallington, New Jersey was used to manufacture natural and synthetic
rubber compounds and chemical adhesives from 1951 to 1983. Solvents used in the manufacturing process included
volatile organic compounds (VOCs) such as acetone, heptane, hexane, methyl ethyl ketone, and methylene chloride, as
well as PCBs. Leaking drums of various chemical compounds were found at the site and soil and groundwater at the site
were determined to be contaminated with PCB Aroclor 1260; semivolatile organic organic compounds (SVOCs) such as
bis (2-ethylhexyl) phthalate (BEHP), 3,3'-dichlorobenzidene, and polyclic aromatic hydrocarbons (PAHs); and metals such
as antimony and arsenic. The site was added to the Superfund National Priorities List (NPL) in March 1989. The ROD
signed in September 1999 specified thermal desorption to address contaminated soil.
From April 1999 to June 2000, thermal desorption was used to treat 53,685 cubic yards of soil. The thermal desorption
unit was a "triple dryer" consisting of a rotating cylindrical kiln with two concentric cylindrical chambers. The unit used
indirect heat at 40 million BTU/hr. Thermal treatment achieved the cleanup goals for PCBs, BEHP, 3,3'-
dichlorobenzidene, and arsenic. Over the course of the cleanup, 16 of the 260 stockpiles of treated soil (approximately 6%)
were retreated because they did not initially meet the cleanup goals. During the performance test, elevated levels of
particulate emissions were identified and the HEPA filter housing was modified, with particulate emissions reduced to
within permitted levels.

Mulch Biowall
Biowall was 455 ft-long, 24 ft-deep, and 1.5 ft-wide; consisted of
approximately 300 cubic yards of shredded mulch (generated by the city), 60
cubic yards of cotton gin compost, and 265 cubic yards of sand
Biowall was installed using a continuous trenching machine, allowing
simultaneous excavation and filling with mulch mixture
Groundwater flows through the biowall under natural hydrualic gradient to
promote contact with the slowly soluble organic matter; microbial processes
in the subsurface degrade the mulch, generating breakdown products
including metabolic acids, that provide secondary electron donors or
fermentable substrates for hydrogen generation, the primary electron donor
used in reductive dechlorination
10 groundwater monitoring wells and 4 soil vapor monitoring points were
installed
Type/Quantity of Media Treated:
Groundwater
Regulatory Requirements/Cleanup Goals:
The objective for this project was to assess the applicability and feasibility of promoting in situ bioremediation of TCE
and cDCE in groundwater, and to contain and attenuate a shallow groundwater plume to prevent surface water
discharge or off-base migration
46
-------
Mulch Biowall at Altus Air Force Base, Landfill 3, Oklahoma (continued)
Results:
After 3 months, the trend of decreasing TCE and increasing cDCE concentrations in groundwater was observed at all
monitoring locations located within 30 ft downgradient of the biowall
Average decrease in TCE concentrations from July 2002 to March 2003 within the biowall was 98.7 percent; the
average decrease in downgradient TCE concentrations was 64.5 percent
As of March 2003, dissolved oxygen levels were depleted in the study area and within the biowall - oxidation-reduction
potential had been lowered; sulfate levels were depleted; hydrogen sulfide and methane levels were elevated; and total
metabolic acids were elevated, indicating that the conditions in the biowall were highly conducive to reductive
dechlorination
Costs:
Capital cost for procuring materials and installing the biowall was $165,000, or approximately $360 per linear foot.
Monitoring cost was approximately $17,000 per event, totaling $51,000 for three events. Future cost of O&M is estimated
to be $42,000, consisting of biannual monitoring, reporting, and project management.
Description:
LF-3 is located at the eastern portion of Altus AFB. LF-3 received waste materials including garbage, wood, paper, metal,
and shop wastes, construction debris, concrete, brush, and several drums of paint waste, which was buried in trenches. Site
investigation identified chlorinated solvents in the groundwater, including TCE and cDCE. A TCE plume extending about
4,000 feet downgradient of LF-3 was identified at the site.
A field demonstration of a mulch biowall was conducted at the site to to assess the applicability and feasibility of
promoting in situ bioremediation of TCE and DCE in groundwater. The mulch biowall was installed using a continuous
trenching machine to simultaneously excavate the trench and install the biowall materials. According to the vendor, this
approach eliminated the concerns associated with open trenches. Data from the groundwater monitoring wells showed that
TCE concentrations were decreasing, reduced by 64.5 to 98.7 percent, and that cDCE concentrations were increasing.
Geochemical parameters measured in March 2003 indicated that the conditions in the biowall were highly conducive to
reductive dechlorination. Additional monitoring is planned to document the ability of the biowall to sustain biological
activity and contaminant mass degradation.

Mulch Biowall
Biowall was 100 ft-long, 23 ft-deep, and 1 ft-wide; consisted of shredded
mulch (generated on-site using shredded trees and leaves) mixed in a 50:50
ratio with coarse sand
Biowall was installed using a continuous trenching machine, allowing
simultaneous excavation and filling with mulch mixture
Groundwater flows through the biowall under natural hydrualic gradient to
promote contact with the slowly-dissolving organic matter; microbial
processes in the subsurface degrade the mulch, generating breakdown
products including metabolic acids, that provide secondary electron donors or
fermentable substrates for hydrogen generation, the primary electron donor
used in reductive dechlorination
8 groundwater monitoring wells (2 upgradient, 4 downgradient, and 2
control)
Type/Quantity of Media Treated:
Groundwater
Regulatory Requirements/Cleanup Goals:
No objectives for the field demonstration were identified
Results:
After 31 months, TCE concentrations 20 ft downgradient of the biowall had been reduced by 70 percent
The ratio of cDCE, a degradation byproduct, to TCE downgradient of the wall increased over 2 orders of magnitude
relative to upgradient conditions after 5 months of treatment; this ratio subsequently dropped as cDCE was converted to
vinyl chloride, ethene, and ethane; the control plot showed no decrease in TCE concentrations
Sampling results showed evidence of that reducing conditions had been established including: depressed oxygen
concentrations and oxygen-reduction potentials due to the consumption of organic matter and oxygen by aerobic
bacteria; nitrate and sulfate levels also declined, while methane production was observed

Mulch Biowall at Offutt Air Force Base, Nebraska (continued)
Costs:
Costs for installing the biowall was $360/linear ft
If mulch for applications had not been generated on-site (at no cost), the estimated cost was approximately $20/yd3
Description:
Offutt Air Force Base in Nebraska was used for the manufacture of aircraft. Wastes from operations resulted in
groundwater at the site becoming contaminated with chlorinated solvents. TCE concentrations in groundwater were found
as high as 2,200 |^g/L where the biowall was installed, with a TCE plume identified at the site extending 3,000 ft.
A field demonstration of a mulch biowall was conducted at the site. The mulch biowall was installed using a continuous
trenching machine to simultaneously excavate the trench and install the biowall materials. Data from the groundwater
monitoring wells showed that, after 31 months, TCE concentrations had been reduced by 70 percent, and that reducing
conditions had been established. Demonstration findings suggested that mulch biowalls are appropriate at sites with
shallow (less than 8 ft) ground water and where the wall extends less than 30 ft below ground surface. Performance data
from the demonstration test indicated that the biowall is a low-maintenance, cost-effective, in-situ treatment wall
technology. Based on these results, a full-scale 500-ft biowall was installed at Offutt AFB in July 2001.

Enhanced In situ Biotransformation at the Naval Weapons Industrial Reserve
Plant, Dallas, Texas (continued)
Results:
Data were provided for six downgradient monitoring wells (three in the upper and three in the lower water-bearing zone)
for baseline samples that were collected in July 1999 prior to installing the treatment system, and again in September 2000.
During this period, TCE concentrations appeared to have been reduced more in the upper water-bearing zone than in the
lower water-bearing zone
In the upper zone, TCE concentrations were reduced from 4,110 to 323 |^g/L and from 3,310 to 345 |^g/L in two out of
the three downgradient monitoring wells. In the third monitoring well, TCE concentrations stayed approximately the
same at 378 |^g/L
In the lower zone, TCE concentrations were reduced from 2,770 to 2,300 |^g/L in one out of the three downgradient
monitoring wells. In the other two wells, TCE concentrations increased from 1,020 to 2,150 |^g/L and from 3,170 to
4,450 ng/L
Costs:
The total cost for the pilot study was $306,557, including $152,903 in capital costs, $72,560 in O&M costs, and $27,094
in other project costs such as reporting and project management
Unit cost was not calculated for this application
No information was provided about the projected cost for use of this technology at full-scale at this site
Description:
The NWIRP in Dallas, TX is an active plant that manufactures and assembles military and commercial aircraft components
and weapons systems. Improper disposal of degreasers in these operations resulted in contamination of the groundwater
with TCE and its daughter products. In October 1999, a field demonstration of enhanced in situ biotransformation was
initiated in an area near Solid Waste Management Unit (SWMU) #15, which was an unlined acid neutralization pit that
received liquid wastes from site operations between 1970 and 1983.
The demonstration consisted of injecting molasses solution into the upper and lower water-bearing zones using two
injection wells, to serve as a supplemental energy source for indigenous microbes and enhance the existing microbial
processes occurring within the subsurface. After an 11 month period, sampling showed that TCE concentrations appeared
to have been reduced more in the upper water-bearing zone than in the lower water-bearing zone. In the upper zone, TCE
concentrations were reduced by more than 85% in two out of the three downgradient monitoring wells, while they stayed
approximately the same in the third well. In the lower zone, TCE concentrations were reduced by approximately 15% in
one out of the three downgradient wells, and increased in the other two wells. No information was provided about the
projected cost for use of this technology at full-scale at this site. During the demonstration, mold was found to be growing
on the molasses solution. As a result, the solution was prepared in batches and automated injection was switched to
manual events followed by thorough cleaning of the molasses mixing tanks.

Technology:
In Situ Bioremediation
At Asian Cleaners, enhanced bioremediation using triethylphosphate and nitrous oxide
was implemented. The system consisted of four biosparging wells screened at 33 to 35
ft bgs - one slant well (installed beneath the drycleaning facility) and three vertical
wells. The radius of influence was 31 to 33 ft, and the injection rate was 1 scfm per
well, sparging from two wells at a time in one-hour intervals twice per day. Injection
concentrations by volume in air were 0.07% to 0.1% for nitrous oxide and 0.007% for
triethylphosphate. Propane was scheduled to be added at the end of the treatment
regimen to improve microbial concentrations. SVE was used to remove vadose zone
contaminants at this site.
At Cypress Village Shopping Center, use of Hydrogen Release Compoundฎ (HRCฎ)
in the bioremediation process has been evaluated but has not yet been approved.
At Dry Clean USA, bioremediation using CL Solutions' Cl-Out was used in a
demonstration. The solution was introduced into the subsurface in two events. Three
injection wells screened between 5 to 10 bgs were used, and approximately 20 gallons
of solution were injected in each well per event, at a rate of 1 gallon - At Tiger
Cleaners, HRCฎ will be injected within and outside the source area, as well as in the
contaminant plume. Within the source area, seven horizontal injection points will be
drilled under the slab of the building, injecting a total amount of approximately 4,000
Ibs of HRCฎ. per minute.
Type/Quantity of Media Treated:

Regulatory Requirements/Cleanup Goals:
At all four sites, cleanup goals were based on state regulatory goals or EPA MCLs.
Specified cleanup goals for groundwater included 3 |^g/L for PCE, 3 |^g/L for TCE, 70 |^g/L for cis-l,2-DCE, 100
for trans-1,2-DCE, and 1 |^g/L for vinyl chloride.
Results:
No information was provided for Asian Cleaners, Cypress Village Shopping Center, or Tiger Cleaners.
At Dry Clean USA, sampling of the source area one month after the second and final injection revealed a decrease in
PCE and TCE concentrations from 48,300 to 96 |^g/L and from 6,110 to 100 |^g/L, respectively. Concentrations of cis-
1,2-DCE and vinyl chloride increased from 2,950 to 94,500 jig/L and from 890 to 2,810 jig/L, respectively.
Costs:
Reported design and implementation cost ranged from approximately $51,000 to $150,000
O&M costs were provided for one site (Asian Cleaners) - $150,000 estimated for 12 months.
Description:
In situ bioremediation was conducted at four drycleaner sites contaminated with chlorinated solvents from dry cleaning
operations with TCE and PCE as the primary contaminants in groundwater. The concentrations of TCE and PCE
contamination varied by site with levels of PCE in groundwater as high as 87,200 |^g/L and TCE in groundwater as high as
28,500 |^g/L. The remediations, including full-scale and demonstration-scale projects, involved the subsurface injection of
substances to promote bioremediation.
In situ bioremediation was performed using triethylphosphate/nitrous oxide at one site and CL Solutions' Cl-Out at
another site. HRCฎ was evaluated for use at the third site, but has not been approved yet. At the fourth site,
bioremediation using HRCฎ was expected to begin in April, 2002. Results from a sampling event in the source area one
month after injection of the Cl-Out solution at Dry Clean USA showed a decrease in PCE and TCE concentrations, and an
increase in cis-1,2-DCE and vinyl chloride concentrations.

Description:
Fort Richardson, established in 1940 as a military staging and supply center during World War II, is located approximately
10 miles northeast of Anchorage, Alaska and occupies about 56,000 acres. Its current mission is to provide services,
facilities, and infrastructure to support the rapid deployment of Army forces. The site was added to the National Priority
List (NPL) in June 1994 and the site cleanup is being addressed under a Federal Facilities Agreement (FFA) to address
contamination at the site. The Poleline Road Waste Disposal Area (PRDA) was used as a disposal area from 1950 to 1972.
Results of a site investigation that soil and groundwater has been contaminated with chlorinated solvents including TCE,
PCE, and TCA.
ERH was evaluated as a potential remediation technology for the site. This report describes the field demonstration of ERH
performed from July through October 1999, conducted in Area A-3 of the PRDA, using heating arrays labeled 4, 5, and 6.
The field demonstration covered a treatment area of approximately 110 feet long by 50 feet wide by 35 feet deep. The
ERH system was constructed in three phases, with each phase including an electrode array (seven electrodes installed to a
depth of 38 feet), three SVE wells, and two thermocouples installed in each phase. The ERH system reduced contaminant
concentrations in groundwater by as much as 75 percent. However, at the end of the demonstration, PCA, PCE, TCE, and
cis-l,2-DCE were above the remedial action objectives. PCE and PCA concentrations in soil were reduced to below the
remedial action objectives; however, TCE concentrations remained above the goal.

-------
Steam Enhanced Extraction (SEE) at the A.G. Communications Systems Site,
Northlake, Illinois (continued)
Results:
Average TCE groundwater concentrations reduced from approximately 20,000 ug/L to <1,000 ug/L over the period
from September 1995 to September 1997
Data from individual wells showed reductions of >90% for TCE and DCE from December 1995 to October 1997
Through November 1999, more than 33,000 Ibs of hydrocarbons had been removed from soil vapor and groundwater;
approximately two-thirds of the contaminant mass was removed as vapor from the two VES units
According to the vendor, based on the site-specific first order degradation constant, the calculated groundwater
concentrations at the point of compliance (property boundary) met Class I remediation objectives; where the soil
concentrations beneath the building exceeded the soil remediation objectives, a theoretical groundwater concentration
leached from the soil was calculated and, along with the site specific degradation constant, was shown to meet the Class
I remediation objectives at the point of compliance
Costs:
Actual cost for the application was $4.9 million and $13 to 15 per cubic yard treated, including the cost of the pilot test,
system design and installation, five years of operation and maintenance, and negotiations with IEPA.
Description:
The A.G. Communications site, located near Chicago, IL, operated as a telecommunications manufacturing facility from
the 1950s through the early 1990s. TCE and mineral spirits used in manufacturing operations were stored in underground
storage tanks (UST). During the decommissioning of the manufacturing facility, TCE, DCE and components of mineral
spirits, including xylene and benzene, were found in soil and groundwater in the vicinity of the former tank farm area and
beneath the manufacturing plant. The site was remediated under the Illinois Environmental Protection Agency (IEPA)
voluntary site remediation program (SRP). A SEE system was pilot tested at the site from January through July 1994, and
full-scale remediation was performed from September 1995 to November 1999.
The full-scale system included shallow vapor extraction wells, shallow and deep steam injection wells, vacuum-enhanced
groundwater/vapor extraction wells, deep groundwater extraction wells, and two vacuum extraction units. Through
November 1999, a total of 33,000 pounds of hydrocarbons had been removed from soil vapor and groundwater, with TCE
and DCE concentrations reduced by more than 90%. In addition to SEE, chemical oxidant flushing using chlorine dioxide
(C102) was performed in recalcitrant source areas. According to the vendor, this approach was used to enhance TCE
partitioning from soil for removal through the groundwater/vapor extraction wells, and redox levels of -100 to -200 mV
were achieved. No additional information about the flushing was provided.

Technology:
Electrical resistive heating (ERH) - Six-Phase Heating
Initial ERH system (May 2000 to May 2001) - 60 electrodes - each capable
of directing power to three zones 20-30 ft bgs, 34-44 ft bgs, and 48-58 ft bgs;
electrodes placed in hexagonal arrays of 6 electrodes each, with a seventh
neutral electrode in the middle of each array; annular borehole spaces packed
with steel shot to improve conductivity and covered with an impermeable
material; 13 subsurface pressure monitoring points and 8 subsurface
thermocouples
95 kW transformer was used to convert standard three-phase electrical power
to six separate phases; initial heating was limited to the bottom interval (45
to 58 feet bgs) to establish a "hot floor" and prevent downward migration of
contamination
During operation, steam and hot water were observed outside the treatment
area; 50 "electrode vents" and the treatment system was expanded in May
2001 to treat areas where contaminated steam and hot water had been
observed
Expanded system - added 13 electrodes, 17 electrode vents, and one
thermocouple
An SVE system, consisting of 53 vapor extraction wells, was used to recover
the steam and contaminant vapors from the unsaturated region immediately
above the heated region (5-10 ft bgs)
Type/Quantity of Media Treated:
Source zone (saturated and unsaturated)
Estimated 48,000 to 65,000 cubic yards based on a treatment area of three-
quarters to one acre in size and a depth of 40 ft
Groundwater - plume size estimated to be 120 ft by 80 ft

-------
Electrical Resistive Heating at the ICN Pharmaceuticals Incorporated Site,
Portland, Oregon (continued)
Regulatory Requirements/Cleanup Goals:
The remedial action objectives specified in the ROD were to prevent and contain migration of separate-phase DNAPL
during treatment and reduce contaminant groundwater concentrations to levels that indicate DNAPL has been removed
or treated
The ROD indicated that the primary goal of the action was to remediate DNAPL and that the residual risk to human
health and the environment and the need for further remediation would be assessed following remediation of the
DNAPL.
Results:
TCE, DCE, and VC concentrations were monitored in the Overbank layer and DCE, VC, and benzene concentrations
were monitored in the TGA layer of the site
As of December 2001, maximum groundwater contaminant concentrations in the Overbank layer had been reduced
from 150,000 ng/L to 100 ng/L for TCE, from 370,000 ng/L to 1,300 ng/L for DCE, and from 24,000 ng/L to 50 ng/L
forVC
Through June 2002, TCE concentrations decreased to 8.11 |^g/L while DCE and VC concentrations were unchanged in
the Overbank layer; the concentrations of all three contaminants were above Oregon MCLs
As of December 2001, the concentrations of DCE and benzene had increased to 49.5 |^g/L and 200 |^g/L, respectively.
VC concentrations decreased from 2.11 |^g/L to not detected
According to the vendor, the increase in benzene concentrations indicated a possible compromise in 3 well casings
which provided a conduit for contamination migration from the Overbank layer and these wells were abandoned in
April 2002
Costs:
No cost data were provided for this application
Description:
The ICN Pharmaceuticals site, located in Portland, Oregon, was used as a clinical laboratory from 1961 to 1980. A variety
of organic and inorganic compounds were used, with wastes from laboratory operations disposed in a 20 ft deep dry well.
Results of sampling conducted in the vicinity of the former dry well showed elevated concentrations of volatile organic
compounds (VOCs) including trichloroethene (TCE), cis-l,2-dichloroethene (DCE), vinyl chloride (VC), benzene, and
toluene in the groundwater, and was determined to be the source of the contamination. During additional investigations,
TCE, DCE, and VC were detected in the groundwater at concentrations greater than 1% of their solubility, suggesting the
presence of dense non-aqueous phase liquid (DNAPL). The ROD for the site specified ERH (Six-Phase Heating) as the
selected remedy to treat DNAPL. ERH, in conjunction with SVE, was conducted at the site from May 2000 to December
2001.
The remedial action objectives for the site were to prevent and contain migration of separate-phase DNAPL during
treatment and to reduce contaminant groundwater concentrations to levels that indicate DNAPL has been removed or
treated. As of December 2001, maximum groundwater contaminant concentrations in the Overbank layer had been
reduced to 100 |^g/L for TCE, 1,300 |^g/L for DCE, and 50 |^g/L for VC with concentrations above Oregon MCLs as of
June 2002. In the TGA layer, concentrations of VC were reduced, but concentrations of DCE and benzene in the TGA
layer increased as a result of a possible compromise in the well casings; these wells were abandoned in April 2002.
Because dissolved phase VOCs remained above DEQ generic risk-based screening levels at various locations at the site,
biosparging was planned for September 2002, as part of the IRAM. Groundwater monitoring at the site is continuing.
Information was not provided about whether the biosparging was implemented and any potential results of the biosparging.

In Situ Thermal Treatment (Electrical Resistive Heating)
Field demonstration of resistive heating - source zone test plot was 75 ft by
50 ft by 45 ft deep
13 electrodes, each consisted of two conductive intervals (25-30 ft bgs and
38-45 ft bgs); lower heating interval configured to provide a "hot floor" for
the treated aquifer; total of 1.7 million kW-hrs of energy applied to the
subsurface (10 to 400 amps)
Novel design for the electrodes used for the demonstration - an electrical
cable attached to a ground rod within a graphite backfill rather than the
traditional pipe electode
12 SVE wells installed with 2-ft screens to depth of 4-6 ft bgs; off-gases
treated with GAC
Two major system interruptions during the demonstration - hurricane in
September 1999 and replacement of a transformer in March 2000
Excessive rainfall from the hurricane caused the water table to rise, resulting
in insufficient heating of the shallow portion of the test plot; to address the
problem, ground rods were installed near the electrodes to heat the 5-10 ft bgs
interval
Type/Quantity of Media Treated:
Soil and Groundwater
Test plot size - 75 ft by 50 ft by 45 ft
Regulatory Requirements/Cleanup Goals:
The objective of the field demonstration was to reduce the contaminant mass by 90 percent
Results:
The mass of TCE and DNAPL in the soil in the test plot was reduced by 90 percent and 97 percent, respectively,
exceeding the target of 90 percent mass removal
Heating was found to be more efficient in the deeper portion of the aquifer, with less heating observed in the shallow
portion
Limitations in the new electrode design and the loss of the vadose zone during the high rainfall event may have
contributed to lower heating of the shallow zone
Sampling hot cores of soil (90ฐC) may have resulted in some losses of chlorinated VOCs during post- demonstration

Costs:
The total cost for the project was $613,000, including $569,000 for resistive heating by the vendor and $44,000 in waste
disposal costs paid by NASA
The $569,000 costs for the resistive heating demonstration included costs for design, equipment,
mobilization/demobilization, and operation
Description:
A 1998 site investigation at the Cape Canaveral Air Force Station in Florida identified a large DNAPL source at Launch
Complex 34. Historical activities at the site included discharging wastes generated from rocket engine and parts cleaning
operations into discharge pits. Chlorinated solvents, including TCE, were used in these cleaning operations. The
Interagency DNAPL Consortium selected this site for demonstrating DNAPL treatment technologies. One of the
technologies tested was resistive heating.
A field demonstration of resistive heating was performed from August 18, 1999 to July 12, 2000, with the post-
demonstration assessment performed from August to December 2000. The resistive heating system included 13 electrodes
with a novel design - an electrical cable attached to a ground rod within a graphite backfill rather than the traditional pipe
electode. During system operation, excessive rainfall resulting from a hurricane raised the water table, resulting in the loss
of the vadose zone, and insufficient heating of the shallow portion of the aquifer. Ground rods were installed near the
electrodes to heat the 5-10 ft bgs interval. Resistive heating reduced the contaminant mass in the test plot by 90 percent for
TCE and 97 percent for DNAPL, exceeding the target of 90 percent mass removal. The vendor used a numebr of
techniques, including capping the ends of the core sample, to reduce the potential for loss of VOCs during sampling of hot
cores.

Technology:
Air Sparging
Total of 10 projects - systems included 6 sites with in situ air sparging and 4
sites with in situ air sparging/SVE; both full-scale and demonstration-scale
projects
Sampling and monitoring procedures varied depending on site conditions and
system configuration; included soil gas testing, vapor sampling, groundwater
sampling, air flow and air injection pressure monitoring, and helium tracers
Type/Quantity of Media Treated:
Soil and Groundwater
Quantity treated varied by site
Regulatory Requirements/Cleanup Goals:
The objective of the study included determining whether the Air Sparging Design Paradigm was effective and valid
based on data collected during the study
Results:
The data supported the necessity to use a suite of diagnostic tests in designing and installing air sparging systems rather
than relying on one type of testing; such diagnostic tests included pressure response testing, deep vadose zone helium
tracer testing, and dissolved oxygen monitoring
The data indicated that the 15-ft well spacing prescribed in the design paradigm would have been sufficient to achieve
adequate treatment of the target zone
Many of the air sparging systems in the study were poorly instrumented and monitored to the extent that system
performance was compromised
Costs:
Costs for the demonstration air sparging system at Port Hueneme, CA was $189,880 or $130 per cubic yard, based on
1,500 cubic yards of soil treated
Projected full-scale costs for this system were $268,490 or $179 per cubic yard based on 1,500 cubic yards of soil
treated

Multi-Site In Situ Air Sparging, Multiple Locations (continued)
Description:
In the mid-1990s, the U.S. Air Force Research Laboratory, Airbase and Environmental Technology Division, Tyndall
AFB, initiated an air sparging project, funded by AFRL/MLQE, SERDP, and U.S. NFSEC. A key goal of the project has
been the development of a technically defensible and praticable Air Sparging Design Paradigm. This paradigm was
evaluated based on information at 10 sites to determine whether it was effective at evaluating air distribution and to use the
results to modify the paradigm.
The 10 sites selected for the study included sites with air sparging systems in place that were being used to treat various
soil types and various contaminants. The results of the study showed that many aspects of the Air Sparging Design
Paradigm were effective, with the results of the study used to develop the final Air Sparging Design Paradigm.

Technology:
Cometabolic Air Sparging
Demonstration system included sparge wells, SVE wells, multi-level
groundwater and soil monitoring points, an air injection system, and SVE
blower, propane gas storage and injection system, and an on-site field trailer;
performed in two phases - Phase 1 focused on groundwater; Phase 2 on
unsaturated zone
Two test plots used for the demonstration - one to test cometabolic air
sparging (injection of air and a gaseous organic growth substrate to promote
in situ cometabolic degradation) and the other to serve as a control; the
cometabolic test plot received propane and air and was identified as the
"active zone"; the "control zone" test plot received air only; the air sparge
wells were located 100 ft apart
Each plot was equipped with an air injection well, air compressor (25 psi and
15 scfm), and six multi-level groundwater and soil gas monitoring points
used to monitor the saturated and vadose zones
Special safely considerations employed to reduce the risk of explosives
hazard from propane
SVE system - one vapor extraction well was installed next to each sparge
well, each well was screened to a depth of 90 ft bgs; designed to extract 45
scfm per well; extracted vapor treated using GAG prior to discharge
After 500 days of operation, propane degradation was not observed in the
saturated zone; methane was substituted for propane to stimulate cometabolic
degradation
Type/Quantity of Media Treated:
Groundwater and soil
523 cubic yards treated during the demonstration
Regulatory Requirements/Cleanup Goals:
The purpose of the demonstration was to evaluate the effectiveness of cometabolic air sparging to remove CAHs from
groundwater; the technology was also evaluated against the MCLs for the target CAHs

-------
Cometabolic Air Sparging at McClellan Air Force Base, OU A, Sacramento, CA
(continued)
Results:
In the saturated zone, CAH concentrations were reduced to near or below the MCLs after about 200 days of operation;
reductions in the active zone were attributed to propane degradation and cometablism; volatilization was observed in
the control zone and contributed to CAH removal
In the vadose zone, after more than 500 days of operation, no CAH cometabolism through propane degradation was
observed, indicating that propane-degrading bacteria were not stimulated during the demonstration; a possible reason
for the lack of degradation was limited nitrogen in the vadose zone
Methane was substituted for propane and was rapidly degraded; levels of CAH decreased after the addition of methane,
suggesting cometabolic degradation by methanotrophs
The propane was also degraded following the addition of methane, suggesting that either methane stimulated the direct
degradation of the propane or that the propane was degraded cometabolically by the growth of methanotrophs in the
vadose zone
Costs:
The costs for the demonstration were $891,800, or $1,705 per cubic yard based on 523 cubic yards treated
Projected full-scale costs were $465,500, or $161 per cubic yard based on 2,888 cubic yards treated
Results of the cost analysis indicated that treatment duration and vadose zone depth had the greatest effect on unit
treatment costs
Description:
The Environmental Security Technology Certification Program (ESTCP) supported an 18-month field study to investigate
use of a cometabolic air sparging (CAS) process at McClellan Air Force Base (AFB). McClellan was placed on the EPA
National Priorities List in 1987 and was designated as a SERDP National Test Site in 1993. A demonstration of
cometabolic air sparging was conducted to evaluate the effectivness and costs of the technology to remove C AHs from the
groundwater. Two test plots were used for the demonstration - one control plot using air injection only and one active plot
where air and propane were injected to test cometabolic air sparging.
Results from the demonstration showed that, after 200 days of operation, CAHs in the saturated zone were reduced to near
or below the MCLs. However, after 500 days of operation, propane degradation had not been observed in the vadose zone
and there was no evidence of CAH cometabolism. Methane was substituted for the propane and was rapidly degraded,
along with the propane, and levels of CAHs were further reduced. These results suggested that a possible lack of nitrogen
in the vadose zone limited propane degradation and that the addition of methane either stimulated direct propane
degradation or that propane was degraded cometabolically by methanotrophs. The overall performance showed that
cometabolic air sparging using propane as the growth substrate was effective in the saturated zone but did not meet
expectations on the vadose zone.

Technology:
Constructed wetlands systems (CWS)
Excavated pits filled with organic matter; two cells constructed
Cells constructed below grade in both upflow and downflow mode
Both cells consisted of a 0.05-acre cell (pit) filled 4 feet deep with a mixture
of an organic-rich compost (96 percent) and alfalfa hay (4 percent)
Base of each cell made up of a gravel subgrade, a 16-ounce geofabric, a sand
layer, a clay liner, and a high-density polyethylene liner
Base separated from influent or effluent piping by a geonet
Each cell designed for a flow of 7 gpm
Metals removed through a combination of sorption, precipitation, and
biological sulfate reduction
Type/Quantity of Media Treated:
Mine drainage
Regulatory Requirements/Cleanup Goals:
Not identified
Results:
Upflow cell removed an average of 93 percent of zinc during the first year of operation, and 49 and 43 percent during
the second and third years
Downflow cell removed an average of 77 percent of zinc during the first year and 70 percent during the second year.
During the final 6 months of operation, loss of permeability in the cell caused an increase in the retention time of the
mine drainage in the cell. This resulted in a higher percentage (82 percent) of zinc removal
Costs:
No information was provided about the cost of this application.

Anaerobic Compost Constructed Wetlands at the Clear Creek/Central City
Superfund site, Burleigh Tunnel, Silver Plume, Colorado (continued)
Description:
As part of the Superfund Innovative Technology Evaluation (SITE) Program, EPA evaluated CWS for removing high
concentrations of zinc from mine drainage at Burleigh Tunnel in Silver Plume, Colorado. The system operated for three
years and treated zinc in the mine drainage through sorption, sulfate reduction, and precipitation of zinc oxides, hydroxides,
and carbonates. Organic-rich compost and alfalfa hay were placed two 0.05-acre, 4 ft deep cells (one upflow and one
downflow). The cells were designed for a flow of 7 gpm.
Results from the upflow cell showed that the constructed wetlands system removed an average of 93 percent of zinc during
the first year of operation, and 49 and 43 percent during the second and third years. The downflow cell removed an
average of 77 percent of zinc during the first year and 70 percent during the second year. During the final 6 months of
operation, the cell showed 82 percent zinc removal. No information was provided about the cost of this application.
During the demonstration, it was noted that the cells can sometimes develop visibly obvious preferential pathways of flow.
This was observed in the upflow cell in 1997, and was addressed by terminating flow to the preferred section, excavating
the wetland substrate, and allowing installation of a cap on the influent line.

Technology:
In Situ Chemical Reduction
In situ chemical reduction using a ZVI slurry (FeroxSM process) with
pneumatic fracturing was pilot tested at SA-2
Pneumatic fracturing was performed using nitrogen gas injected into the
ground at 120 pounds per square inch (psi). The gas was used to create
preferential pathways in the low permeability, capillary fringe media above
the rubble zone
Following fracturing, ZVI powder was mixed with water under pressure to
form a slurry; the slurry was injected into subsurface target intervals using the
patented LAI system; a specialized nozzle (capable of delivering the
atomized fluids in up to a 360-degree pattern) was used to atomize the
injected fluids to improve dispersal into the target zone
11,000 pounds of ZVI was injected to reduce 55 pounds of TCE; field ratio
of iron to TCE by weight was 200:1; average slurry delivery pressure - 60 psi
Regulatory Requirements/Cleanup Goals:
The objective of the pilot test was to evaluate the effectiveness of in situ
chemical reduction using the ZVI FeroxSM process to treat TCE in SA-2
No specific cleanup targets were identified for the pilot test

-------
In Situ Chemical Reduction at the Marshall Space Flight Center,
Source Area 2, Huntsville, Alabama (continued)
Results:
During the period from July 2000 to March 2002, the ZVI chemical reduction pilot test in SA-2 reduced the
concentrations of TCE in two source area monitoring wells by 52 and 90%, respectively
TCE concentrations were reduced during the first 13 months after injection and then began to show increases, possibly
indicating rebound; MSFC plans to continue groundwater monitoring on a quarterly basis to evaluate the potential for
rebound
As of March 2002, TCE degradation products, including DCE, VC, and chloride, were identified in the groundwater,
and the redox potential for the groundwater changed to highly reducing conditions, indicating that the chemical
reduction process was affecting groundwater quality
Costs:
The cost to implement the pilot test was $27 per pound of ZVI injected
The actual field demonstration portion of the test was approximately 70 percent of the total costs ($209,900),
corresponding to about $19 per pound of ZVI injected
Description:
The Marshall Space Flight Center (MSFC) is a federal research and development facility located within the Redstone
Arsenal (RSA) in Huntsville, Alabama. During the 1940's, RSA was used for manufacturing munitions and from 1949 to
1960 for developing rockets and guided missile systems. Since 1960, when the civilian rocketry and mission activities
were transferred to the National Aeronautics and Space Administration (NASA), MSFC has been used to support the space
program, including developing spacecraft and rocket engines. Historical solvent waste management practices from rocket
engine testing operations at MSFC resulted in contamination of soil and groundwater at the facility, primarily with
chlorinated volatile organic compounds (cVOCs). Site investigations identified five major cVOC plumes at MSFC along
with 14 contaminant source areas that may act as continuing sources of groundwater contamination.
A pilot test of in situ chemical reduction technology was performed to assess the ability of the technology to treat dissolved
TCE in the residuum groundwater beneath the Source Area 2 (SA-2) area. SA-2 was the location of a pond (CERCLA Site
MSFC-005) that had received TCE from engine cleaning operations and had overflowed through a concrete trough to
surrounding soils. The presence of unexploded ordnance (UXO) within the subsurface beneath the SA-2 area affected the
design and operation of the pilot test; clearance of all subsurface sampling, injection and permanent groundwater
monitoring points was required the injection of ZVI slurry in many areas having the highest groundwater concentrations
was limited. Through March 2002, the ZVI chemical reduction pilot test in SA-2 reduced the concentrations of TCE in two
source area monitoring wells by 52 and 90%, respectively, and other parameters indicate that chemical reduction is
occurring. Because of concern about possible rebound, MSFC plans to continue groundwater monitoring on a quarterly
basis to evaluate the potential for rebound.

Swift Cleaners - December 2000 - April 2002
Cleanup Authority:
State
Purpose/Significance of Application:
Use of in situ oxidation technologies for remediation of chlorinated solvents
in groundwater at drycleaner facilities
Cleanup Type:
Full scale
Contaminants:
Chlorinated Solvents
Both sites were contaminated with PCE and TCE
Concentrations varied at the two sites, ranging from 4,400 to 10,000
Hg/L for PCE, and 24 to 382 ng/L for TCE
Ineeda Cleaners also reported the presence of cis 1,2-DCE at 134
Both sites reported that DNAPLs were present.
Waste Source:
Waste and wastewater from drycleaning
operations
Contacts:
Varied by site
Technology:
In situ chemical oxidation
At Ineeda Cleaners, three KVA C-Sparger wells were installed to surround
the main groundwater contamination area, and ozone was injected to oxidize
contaminants.
At Swift Cleaners, 400 to 600 gallons of 14%-15% hydrogen peroxide (plus
catalyst) were injected in two separate areas, IA and IB. In area IA, 12 wells
were used, with 2 injections per well. In area IB, 13 wells were used, with 2
injections per well. For both areas, the radius of influence was 7.5 ft.
During a third injection in areas IA and IB, a total of 600 gallons of 15%
hydrogen peroxide was injected in 11 wells.
Type/Quantity of Media Treated:
Groundwater
Reported plume areas ranged from 300,000 ft2 to 12,000,000 ft2, and reported
plume depths ranged from 50 to 56 ft bgs. For Swift Cleaners, the reported
actual treatment area was 4,500 ft2 and the reported actual treatment depth
ranged from 35 to 45 feet. This information was not provided for Ineeda
Cleaners.
Regulatory Requirements/Cleanup Goals:
Cleanup goals were based on EPA MCLs, reported for Swift Cleaners as 3.0 |^g/L for PCE and TCE; cleanup goals were
not reported for Ineeda Cleaners.
Results:
At Ineeda Cleaners, groundwater concentrations were not significantly reduced during the operation of the KVA
system. The system experienced maintenance problems, which may have affected performance.
At Swift Cleaners, contaminant levels were not reduced to below cleanup goals. First quarter sampling showed that
PCE concentrations were reduced to below 200 |^g/L. Second quarter sampling showed that several wells showed a
rebound, with PCE concentrations rising to above the baseline level of 1,050 |^g/L. Results of the third injection (in
both areas IA and IB) continued to show contaminant rebound.
Costs:
Reported design and implementation costs:
Ineeda Cleaners: $100,900
Swift Cleaners: $245,000

In Situ Chemical Oxidation at Two Drycleaner Sites, Hutchinson, Kansas
and Jacksonville, Florida (continued)
Description:
In situ chemical oxidation was conducted at two dry cleaner sites contaminated with chlorinated solvents from drycleaning
operations with TCE and PCE as the primary contaminants in groundwater. The concentration of PCE and TCE varied
between the two sites, ranging from 4,400 to 10,000 |^g/L for PCE, and 24 to 382 |^g/L for TCE. Reported plume areas
ranged from 300,00 ft2 to 12,000,000 ft2, and reported plume depths ranged from 50 to 56 bgs. The remediation involved
in situ chemical oxidation at full-scale at both sites.
At one site, ozone was injected into the subsurface, and at the other site, hydrogen peroxide and catalyst (Fenton's
chemistry) were injected into the subsurface. The cleanup goal of EPA MCLs was not met at either site after up to 3
rounds of injection. At Ineeda Cleaners, this was attributed to problems with the KVA C-Sparger wells. At Swift
Cleaners, rebound concentrations of PCE were observed after three injection events. Subsequent remediation efforts will
be conducted at this site in three additional phases proceeding downgradient.

Technology:
In Situ Chemical Oxidation (ISCO)
Field demonstration of ISCO - source zone test plot was 75 ft by 50 ft by 45
ft deep
A total of 842,985 gal of permanganate solution (1.4 to 2 percent) was
injected into the test plot in 3 phases over a period of 8 months; vendor
designed and supplied a continuous mix and automated feed system for the
demonstration
First injection September to October 1999 - a total of 304,763 gallons of
solution were injected, first into the upper unit, then into the middle unit,
followed by the lower unit; a GeoProbe equipped with a specially designed
tip was used to inject the solution; the estimated radius of influence was 10-
12 ft; however, local heterogeneities limited oxidant distribution in some
areas
The second (November 1999) and third (March to April 2000) injections -
focused only on those portions of the plot where interim monitoring results
showed that the area had not received sufficient oxidant during the previous
cycle; a total of 87,483 gallons of solution were injected during the second
cycle and 450,739 gallons during the third cycle
One major system interruption occurred during the demonstration - hurricane
in September 1999
Type/Quantity of Media Treated:
Groundwater
Test plot size - 75 ft by 50 ft by 45 ft
Regulatory Requirements/Cleanup Goals:
The objective of the field demonstration was to reduce the contaminant mass by 90 percent
Results:
The mass of TCE and DNAPL was reduced by 77 percent and 76 percent, respectively; while less than the target of 90
percent, the removal percentage was considered to be significant for the technology
The highest level of removal was observed in the upper sand zone, indicating that the oxidant distribution was most
efficient in the coarser soils in this zone
TCE and DNAPL removal pathways included destruction by oxidation, migration to the surrounding aquifer, and
migration to the vadose zone and atmosphere
Dissolved TCE levels decreased in most parts of the test plot, with several monitoring wells showing levels below the
MCL of 5

In Situ Chemical Oxidation (ISCO) Treatment of DNAPL Source Zone at Launch
Complex 34, Cape Canaveral Air Force Station, Florida (continued)
Costs:
The total cost for the field demonstration was approximately $1 million, including costs for design, procurement,
equipment and oxidant, mobilization/demobilization, and process monitoring
The vendor indicated that about 15 percent of the cost was due to use of the technology at a demonstration rather than a
full-scale application
Description:
A 1998 site investigation at the Cape Canaveral Air Force Station in Florida identified a large DNAPL source at Launch
Complex 34. Historical activities at the site included discharging wastes generated from rocket engine and parts cleaning
operations into discharge pits. Chlorinated solvents, including TCE, were used in these cleaning operations. The
Interagency DNAPL Consortium selected this site for demonstrating DNAPL treatment technologies. One of the
technologies tested was in situ chemical oxidation (ISCO).
A field demonstration of ISCO was performed from September 8, 1999 to April 17, 2000, with the post- demonstration
monitoring performed through February 2001. During the 8-month demonstration, more than 840,000 gallons of
permanganate solution were injected in three phases. Following the first injection, monitoring results showed that local
heterogeneities limited oxidant distribution in some areas. A second and third phase of injections were performed,
focusing on those portions of the plot where interim monitoring results showed that the area had not received sufficient
oxidant during the previous cycle. ISCO reduced the concentrations of dissolved TCE in the groundwater and reduced the
mass of TCE and DNAPL in the test plot by 77 percent and 76 percent, respectively. While less than the target of 90
percent, the removal percentage was considered to be significant for the technology. The best distribution of the oxidant
occurred in the upper sandy soils; distribution of oxidant was more difficult in finer-grained soils. Local geologic
heterogeneities and native organic matter content may limit oxidant distribution in some regions.

Permeable Reactive Barrier (PRB)
Funnel and gate designs were used at Moffett, Lowry, and Dover
Continuous wall was used at Seneca
Moffett: gate 10 ft wide; granular iron supplied by Peerless Metal Powders,
Inc.
Lowry: iron supplied by Master Builders Supply
Seneca: 600 ft long continuous trench, 1 ft wide, keyed into competent shale
bedrock 5-10 ft bgs; barrier consists of 50:50 mixture of sand and iron
Dover: interlocking sheet piles used for funnel and caisson excavations filled
with iron constitute 2 gates
Type/Quantity of Media Treated:
Groundwater
Moffett: Hydraulic conductivity of channel sand and gravel - 150 ft/day,
porosity - 0.30
Lowry: Silty-sand to sand and gravel unconfined aquifer over weathered
claystone bedrock; some heterogeneity
Seneca: Fractured shale and overlying glacial till; unconfined aquifer
Dover: Unconfined silty sand deposits overlying a thick clayey confining layer;
fairly homogeneous; hydraulic gradient fairly low (0.002) and variable
Regulatory Requirements/Cleanup Goals:
The objectives for the demonstration were to evaluate longevity and hydraulic performance of PRBs at sites with varying
hydogeologic conditions; no specific cleanup goals were identified
Results:
Longevity was evaluated at Moffett Field and Lowry AFB using accelerated column tests, looking at changes in the
reaction rates (half lives) of contaminants when the iron was exposed to many pore volumes of contaminated
groundwater; actual groundwater from the two sites was used
The PRBs at Moffett and Lowry had projected lifetimes of approximately 30 years, based on the time period over
which the reactivity of the iron would decline by a factor of two
Hydraulic performance was evaluated at all four sites based on a characterization of the flow regime around existing
field barriers, and on results from groundwater modelling of the factors that determine flow, looking at groundwater
capture zones and residence times
The hydraulic evaluation showed that careful water level measurements combined with groundwater modeling provided
the best results, sometimes contrasting with results from direct flow measurements

Permeable Reactive Barrier Longevity and Hydraulic Performance at
Four DoD Sites (continued)
Costs:
A present value analysis of the projected costs for a PRB and comparable pump and treat system showed that it would
take approximately 7 to 10 years to obtain a payback on the initial capital investment in a PRB
Cost for field demonstration of PRB at Moffett was reported as $802,375, consisting of $652,375 in capital costs and
$150,000 in O&M costs (based on 5 monitoring events)
Cost for field demonstration of PRB at Dover was reported as $739,000, consisting of $365,000 for pre-construction
activities and $374,000 for PRB construction
Description:
Naval Air Station (NAS) Moffett Field and Lowry Air Force Base (AFB) are former DoD operational facilities that have
groundwater contaminated with halogenated volatile compounds. Both sites had installed PRBs and had historical
information available about field operation of the PRBs. The sites were evaluated to determine expected longevity of the
PRBs, including groundwater geochemistry monitoring, iron core collection and analysis, geochemical modeling, and
accelerated column tests. These tests showed that the reactivity of the iron declined with long-term exposure to
groundwater and was related to the concentration of dissolved solids and rate of groundwater flow through the reactive
media.
Hydraulic performance was evaluated for PRBs at Moffett Field, Lowry AFB, Seneca Army Depot, and Dover AFB.
Moffett, Lowry, and Dover used funnel and gate configurations, while Seneca used a continuous trench design. The
hydraulic performance was evaluated using water level measurements and slug tests, HydroTechnics flow sensors and
colloidal borescope, and groundwater flow and solute transport modeling. Results showed that careful water level
measurements combined with groundwater modeling provided the best results for hydraulic performance. These results
sometimes contrasted with the results from direct flow measurements, possibly due to localized differences in groundwater
flow conditions.

Breakthrough - no breakthrough was observed in the column effluent; complete breakthrough was observed at the first
sampling port on the column (1/3 column length), and 20 percent breakthrough was observed at the second sampling
port (2/3 column length)
Residence time was determined to be 27 seconds which was considered to be a very short time for complete capture of
the pertechnetate
Results also showed that the resin was particularly effective in removing low levels of pertechnetate (in the nmol/L
range); BiQuat was determined to be approximately fives times more effective than the commercial Purolite A-520E
resin for Tc removal

Bi-functional Resin Groundwater Treatment at Paducah Gaseous Diffusion Plant,
Kentucky (continued)
Costs:
Information about the capital costs, operating and maintenance costs, and costs of scale-up were not available
The estimated cost of the BiQuat resin was $ 1,000 per cubic foot; this cost is approximately five times the cost of the
commercial Purolite A-520E resin for Tc removal; however, because the BiQuat resin is about fives times more
efficient than Purolite A-520E, the costs would be approximately the same for the two resins
Resin regeneration is economically desirable, given the relatively high cost of BiQuat
Description:
At DOE's Paducah Gaseous Diffusion Plant in Kentucky, wastewater from processing uranium and plutonium were
discharged to lagoons and pits. The wastewater was frequently contaminated with Tc, and a contaminant plume is present
in the sandy aquifer at the site below the vadose zone. The Tc is present in the groundwater as the pertechnetate anion,
which is highly mobile. New bi-functional anion exchange resins that are highly selective for pertechnetate have been
designed and are being tested as part of a research project at the Oak Ridge National Laboratory and the University of
Tennessee.
A field demonstration was performed using the BiQuat anion-exchange resin, a resin containing trihexylammonium and
triethylammonium exchange sites. The demonstration system included a 12 inch resin packed column with a flow rate of
about 2.5 gallons per minute. The demonstration showed that the resin was effective in removing pertechnetate, especially
at low levels, and that the resin was five times more efficient than the best competing resin (Purolite A-520). However, the
cost of the BiQuat resin is relatively high (about $1,000 per cubic foot). A large-scale application of the technology would
be needed to make the use of the resin commercially viable.
