This report is a collection of abstracts summarizing 39 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 313 remediation technology case studies (the 39 new
case studies and 274 previously-published case studies). Appendix A to this report identifies the specific
sites, technologies, contaminants, media, and year published for the 313 case studies.

Abstracts, Volume 6, 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. Previously, the Roundtable published 13 volumes and a CD-ROM of
case study reports. At this time, the Roundtable is publishing a CD-ROM containing 39 new case study
reports (313 reports total), primarily focused on contaminated soil and groundwater cleanup. The CD-
ROM also includes 274 previously published reports.

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).

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 39 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).

By including a recommended reporting format, the Roundtable is working to standardize the reporting of
costs 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.

Appendix A to this report provides a summary of key information about all 313 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.

•  SVE systems consisted of from 1 to 14 vapor extraction wells applying a vacuum of 19 to 70 inches
   of water and drawing 80 to 290 scfm of soil vapor at depths from 0.5 to 40 feet bgs. Two system
   also had air injection wells.
•  At three sites pump and treat of contaminated groundwater was also conducted.  The groundwater
   pump and treat continued operation for an unspecified period of time after the SVE system was
   shut down.
•  At two sites, prior to SVE, excavation of hot spots was performed. At one of those sites the
   excavation was followed by backfilling and capping with asphalt to minimize infiltration of surface
   water into the contaminated areas.
                   Type/Quantity of Media Treated:
                   Soil
Regulatory Requirements/Cleanup Goals:
•  Soil cleanup goals were based on state regulatory goals
•  Five sites had a soil cleanup goal of 30 mg/kg leachable PCE; one site had a soil cleanup goal 0.3 mg/kg for PCE.
Results:
• All of the sites reported that SVE effectively removed PCE from soils
• The amounts of VOCs removed by the SVE systems ranged from 2 to? pounds
Costs:
Design and implementation costs for SVE systems ranged from $30,000 to $160,000; annual O&M costs for SVE systems
ranged from $26,000 to $67,000

Purpose/Significance of Application:
Field demonstration of a photocatalytic reactor to treat off-gas from soil vapor
extraction (SVE) and multi-phase extraction (MPE)
                                    Cleanup Type:
                                    Field demonstration
Contaminants:
Chlonnated VOCs
• 94% of the contaminant mass in off-gas was TCE
                                   Waste Source:
                                   Off-gas from SVE and MPE
Technology:
Photocatalytic oxidation
• The contaminated air stream flows into the reactor where VOCs are adsorbed
  onto the surface of a proprietary catalyst that is continuously illuminated with
  UV light, oxidizing the VOCs.
• The unit operated at flow rates ranging from 490 to 600 scfrn.
• The average power consumption was 15 kilowatts.
                                    Type/Quantity of Media Treated:
                                    Off-gas
Regulatory Requirements/Cleanup Goals:
• Contaminant removal efficiency (CRE) of 95% or higher for TCE
• Demonstrate effective TCE removal over an extended operational period (numerical goal not specified).
• State emissions standards for VOC emissions from the water scrubber following the photocatalytic reactor below the
  Rhode Island emissions standard for TCE and chloroform of 0.02 and 0.002 pounds per hour, respectively
Results:
• The observed CRE for TCE was 99.6%
• TCE emissions rom the water scrubber following the photocatalytic reactor ranged from 0.00039 to 0.0023 pounds per
  hour.  TCE concentrations ranged from 0.038 to 0.19 ppmv.
• Chloroform emissions from the water scrubber following the photocatalytic reactor ranged from 0.00041 to 0.0050
  pounds per hour
Costs:

 Photocatalytic Reactor for Treatment of SVE and MPE Off-Gas at the Stamina
                 Mills Superfund Site, North Smithfield, RI (continued)
Description:
The Stamina Mills Superfund site is a former textile manufacturing facility. Spills of solvents used to clean fabrics
manufactured at the plant resulted in contamination of soil and groundwater. SVE and MPE systems are currently
operating at the site to clean up the contamination.

A demonstration test of a photocatalytic oxidation system was conducted under the U.S. EPA Superfund Innovative
Technology Evaluation Program (SITE). Off-gas from the SVE and MPE systems was treated using the photocatalytic
oxidation system from August to October, 1999. Treatment goals for TCE were met. The vendor indicated that chloroform
emissions from the scrubber could be reduced through the use of alternative photocatalysts or reactor configurations.

Technology:
Natural Pressure-Driven Passive Bioventing
• Uses the force generated by normal daily fluctuations in atmospheric
  conditions to replace a powered blower for injecting air into the subsurface
• A single vent well was installed to a depth of 65 feet with three isolated 10-
  foot screened sections to evaluate airflow rates in three different lithologic
  zones
• The radius of influence of the bioventing well was estimated at 42 feet after
  seven weeks
• The daily airflow rates ranged from 27 to 9300 ft3 per day and averaged 3,400
  ft3 per day
                                      Type/Quantity of Media Treated:
                                      Soil
                                      •  Upper 20 ft of subsurface comprised of silty sand overlying a laterally
                                        continuous silt layer between 20 and 25 ft
                                      •  Soil moisture - average about 6%
Regulatory Requirements/Cleanup Goals:
•  Goals of the demonstration included achieving consistent air flow rate to vadose zone greater than 1 cfm and 1,200
   cubic feet per day and a radius of influence greater than 10 feet
•  No specific cleanup levels were identified for the demonstration
Results:
• Air supply during demonstration consistently exceeded goals of 1 cfm and 1,200 cubic feet per day; ranged from 27 to
  9300 cubic feet per day (cfd), and averaged 3,400 cfd
• The radius of influence was estimated to be 42 feet after seven weeks, exceeding the goal of 10 feet.
• As areas near the well are remediated and the oxygen demand is satisfied, the predicted radius of influence would be
  expected to be 85 feet, comparing favorably to conventional bioventing radius of influence of 110 feet
Costs:
•  The estimated cost of a full-scale passive bioventing system was $1.93 per cubic yard of soil treated. The cost of
   conventional bioventing was estimated at $2.09 per cubic yard
•  Passive bioventing would require the use of 1.5 times as many wells as conventional bioventing, and a treatment time of
   4 years instead of 3 years at the Castle Airport Site, however an overall reduction in costs would be achieved by
   eliminating the capital cost of blowers and the O&M cost of powering the blowers.

          Natural Pressure-Driven Passive Bioremediation at Castle Airport,
                                       Merced, CA (continued)
Description:
A demonstration of natural pressure-driven passive bioventing was performed at Castle Airport in Merced, CA The
petroleum oil and lubricants fuel farm area was the bulk fuel storage and distribution facility for the former AFB located at
the site. Soil and groundwater contamination resulted from leaking underground storage tanks and fuel distribution lines
and surface spills.  The Department of Defense Environmental Security Technology Certification Program (ESTCP), the Air
Force Research Laboratory, and Naval Facilities Engineering Service Center, and the Air Force Center for Environmental
Excellence (AFCEE) cooperated in conducting the demonstration.

Natural pressure-driven passive bioventing is similar to conventional bioventing with the exception that it uses the force
generated by normal daily fluctuations in atmospheric conditions to replace a powered blower for injecting air into the
subsurface.  During the demonstration, six tests of natural pressure-driven passive bioventing were performed over a six
month period. A single well installed to a depth of 65 feet achieved an average daily air flow rate to the vadose zone of
3,400 cubic feet and a radius of influence of 42 feet. As areas near the well are remediated and the oxygen demand is
satisfied, the predicted radius of influence would be expected to be 85 feet, comparing favorably to conventional
bioventing radius of influence of 110 feet. The projected cost of a full-scale passive bioventing system was $1.93 per cubic
yard of soil treated, compared to $2.09 per cubic yard for conventional bioventing.

Description:
The seven-acre Magic Marker site located in Trenton, NJ is an urban area "Brownfield." The site was used for lead-acid
battery manufacturing from 1947 to 1979 and then by the Magic Marker facility up until its closure in 1987. A
demonstration was performed under the Superfund Innovative Technology Evaluation (SITE) program between May 1997
and November 1998 to determine whether phytoremediation could effectively reduce lead contamination in surface soils.
The demonstration included planting and harvesting two crops of Indian Mustard (Brassicajuncea) in 1997 and a crop of
sunflowers (Helianthus annus) in 1998.  The demonstration achieved its objectives of 200 mg/kg lead in above-ground
plant tissues and reduction of soil lead concentrations by  15%.

The soil at SAFR 24 at Fort Dix, NJ was determined to be contaminated with lead, including spent bullets and bullet
fragments. A joint demonstration with the U.S. Department of Defense RangeSafe Technology Demonstration Initiative
(RTDI) and the SITE program was performed to evaluate the use of soil washing followed by phytoremediation to treat
lead in soil at the site. After soil washing, the soil was placed in a 1.25 acre ex situ lined treatment cell, where the
phytoremediation was conducted.  The demonstration included planting and harvesting three crops during the 2000
growing season: (1) Indian Mustard (Brassicajuncea), (2) sunflowers (Helianthus annus), and (3) a mixture of rye (Secale
cereale) and barley (Hordeum vulgare). The demonstration achieved its treatment objective of reducing lead
concentrations to below 400 mg/kg.

Electrokinetic remediation
•  System included an array of electrode wells, power supply and control system
   , monitoring system, process piping to distribute chemicals to and extract
   contaminants from electrode wells, and off-gas treatment system
•  Electrode array consisted of a series of 24 anode and 14 cathode wells for two
   lagoons in the test cell; anode wells were 4 inch slotted PVC casings wrapped
   in linen fabric; anodes were rod-shaped and constructed of titanium with
   iridium oxide coating; cathode wells were 3-inch porous ceramic casings;
   cathodes were 2-inch wide strips of stainless steel mesh
•  Citric acid was used as a soil amendment to enhance contaminant mobility
•  Current density -0.1 mA/cm2 for about 3 months; increased to 0.2 mA/cm2 in
   effort to raise contaminant movement; after six week shutdown to review
   project, current density further increased to 0.33 mA/cm2 with a
   corresponding decrease in the size of the treatment cell to one lagoon
•  Prior to field demonstration, extensive laboratory testing was conducted to
   assess the potential effectiveness of electrokinetic extraction at the site;
   results indicated the technology could be successfully applied at the
   demonstration site
                                      Type/Quantity of Media Treated:

                                      •  Approximately 0.5 acres
                                      •  85% sand, 7% gravel, 6% silt, and 1% clay
                                      •  pH of 5.84, TOC of 6,390 mg/kg, hydraulic conductivity of 0.045 cm/sec, cation
                                        exchange capacity of 3.9
Regulatory Requirements/Cleanup Goals:
•  Site target cleanup levels are State of California limits for chromium of <2,500 mg/kg and cadmium of 100 mg/kg
Results:
• After 22 weeks of operation, contaminant reduction goals were not met; a pH front was just beginning to develop, with
  limited contaminant movement; the demonstration was suspended in October 1998
• Control of electrokinetically mobilized contaminants within the confined and unconfined treatment areas could not be
  assessed due to the poor performance of the technology.
• There was an increase in soil VOCs, primarily due to trihalomethane production resulting from Cl buildup in the anode
  wells
•  The high  chloride concentration of the groundwater was the main site characteristic that lengthened the time required
  to extract  contaminants from the soil

Costs:
• Proj ected full-scale costs of $ 1,193/C Y were extrapolated from the costs incurred for the field demonstration
• The total projected cost was $1,193,050 for treatment of 1,000 CY, consisting of $890,988 for capital and $302,062 for
  O&M
Description:
Site 5 at NAWS Point Mugu was used for electroplating and metal finishing operations.  Wastewater was discharges to
unlined lagoons, resulting in soil and groundwater contamination at the site. A demonstration of electrokinetic
remediation was performed from March to October 1998 to treat soil at the site. The demonstration was conducted by the
U.S. Army Environmental Center (USAEC), Engineer Research and Development Center (ERDC); the Environmental
Security Technology Certification Program (ESTCP) and Southwest Division, Naval Facilities Engineering Command.

The electrokinetic remediation system demonstrated consisted of a series of anode wells and cathode wells arrayed in the
test cell. Citric acid was used as a soil amendment to enhance contaminant mobility.  The initial current density applied to
the system was increased after about three months of operation in an effort to increase contaminant mobility. The current
density was further increased with a corresponding decrease in the size of the test area in additional efforts to increase
contaminant mobility. However, after 22 weeks of operation, the pH front was just beginning to appear with limited
contaminant removal; the demonstration was suspended in October 1998.  The bench-scale tests did not accurately reflect
the effects of site conditions on performance. A projected full-scale cost for use of the technology was estimated as more
than $l,100/cubic yard of soil treated.

  Biocell Technology, Ex Situ Bioremediation of Petroleum-Contaminated Soils,
                                  Port Hueneme, CA (continued)
Description:
Navy installations generate petroleum-contaminated soils from a variety of operations including fuel storage, vehicle
maintenance and repair, and training areas where fuel has been spilled on the ground.  For small quantities of petroleum-
contaminated soil, off-site disposal can be expensive.  The biocell technology, an ex situ bioremediation system, provides
a potential alternative to off-site disposal for treating small quantities of soil contaminated with low to intermediate
concentrations of petroleum hydrocarbons.

The Naval Facilities Engineering Service Center conducted a demonstration of the biocell technology for petroleum-
contaminated soils at the Naval Construction Battalion Center's (NCBC) Hydrocarbon National Test Site in Port Hueneme,
California. The system used for the demonstration was a 10 cubic yard biocell built using a commercially available roll-off
container.  After 105 days of operation, TPH concentrations in the soil were reduced from 736 mg/kg to 147 mg/kg. The
estimated unit costs for operating a 40 cubic yard biocell ranged from about $35 to $40 per cubic yard of soil treated,
depending on the number of biocells.  Several benefits were identified for biocell technology including relatively easy
design and construction, potential applicability to a wide range of site conditions, and biocells may be cost-competitive
with off-site disposal.

   $8,088,046 on O&M costs
•  The unit cost for this application was $58/ton based on treating 170,300 tons of soil
Description:
The Cape Fear Superfund Site is located on 41 acres in Fayetteville, North Carolina. The site was operated as a wood
preserving facility from 1953 to 1983, first using a creosote process and, starting in 1970, using a copper-chromated-
arsenate (CCA) process. Liquid and sludge wastes generated by both of these processes were pumped into a drainage
ditch and an unlined lagoon.  Investigations at the site by EPA and the State of North Carolina showed that soil at the site
was contaminated with polycyclic aromatic hydrocarbons (PAHs), benzene, and metals including arsenic and chromium.  A
Record of Decision (ROD), signed in June 1989, specified excavation and soil washing to address the soil contamination
from the drainage ditch and unlined lagoon.  However, initial soil washing operations did not meet the cleanup goals for
carcinogenic PAHs. and EPA made the decision to implement the contingent remedy, low temperature thermal desorption.

The thermal treatment system used for this application was a low temperature thermal desorption system owned by
Williams Environmental Services, Inc. A demonstration test was performed July 20 - 22, 1998 during which 1,900 cubic
yards of soil were treated.  Full-scale thermal desorption was conducted from July 1998 to April 1999 during which 170,300
tons of soil were treated. The total costs for the thermal treatment application $9,888,575 ($58/ton of soil treated). This
completed project involved the largest quantity of soil treated using thermal desorption the U.S. at the time the project was
performed.

Results:
Available performance data for this application is limited to the results of the performance test conducted in May 1995.
The results show that, with the exception of molybdenum, all soil cleanup targets were met during the test.  According to
the vendor, the elevated concentrations of molybdenum were due to its use in the grease on the front-end loader used to
transport soil.

While no concentration data were provided for treated soil other than for the performance test, the vendor reported that,
ninety-five percent of the soil was treated to below the  cleanup goals on the initial pass through the desorber.  The soil
that did not meet the cleanup goal for bis (2-chloroethyl) ether was retreated to meet the cleanup goal.
Costs:
•  The total cost for the thermal treatment application at this site was $6,082,029, including $430,000 in capital cost and
   $5,019,292 in O&M costs
•  The unit cost for this application was $68/ton based on treating 80,000 tons of soil
Description:
The Lipari Landfill (Lipari) site was used for disposal of a variety of household, chemical, and other industrial wastes from
1958 to 1971.  Approximately 3 million gallons of liquid wastes and 12,000 cubic yards of solid wastes were disposed of in
trenches originally excavated for sand and gravel.  The wastes included solvents, paints and thinners, formaldehyde, dust
collector residues, resins, and solid press cakes from the industrial production of paints and solvents. The Lipari Landfill
was closed by the New Jersey Department of Environmental Protection in 1971  and added to the National Priorities List in
September 1983. In July 1988, EPA signed a Record of Decision to clean up Operable Unit (OU) 3 (off site contamination) at
Lipari  using thermal desorption for soil and sediment from a marsh area.

The thermal treatment system used for this application was a low temperature thermal desorption system owned by
Williams Environmental Services, Inc. Thermal desorption was conducted at the site from September  1994 to September
1995, including a five month downtime to rebuild a baghouse used for treating the off-gas from the thermal desorber.  A
total of 80,000 tons of contaminated soil and sediment were treated during this application. The total costs for the thermal
treatment application $6,082,029 ($68/ton of soil treated).  The presence of elevated levels of sulfur pyrite in soil treated
through the desorber caused a fire in the baghouse partway through the project.  The fire destroyed the baghouse and
delayed completion of the project by five months.  The high moisture content of the soil (20 to 30%) obtained from the
marsh limited the throughput, and lime was added to the soil to reduce the moisture content and improve material handling.

Description:
The 120-acre Reilly Industries Superfund site (Reilly), previously known as Reilly Tar & Chemical (Indianapolis Plant), is a
former coal tar refinery and creosote wood treatment plant located in Indianapolis, Indiana. The site includes the following
five waste disposal areas: the Lime Pond area; the Abandoned Railway Trench; the Former Sludge Treatment Pit; the
Former Drainage Ditch; and the South Landfill and Fire Pond. The Reilly site was added to the National Priorities List
(NPL) in 1984. Contaminants of concern in the soil included PAHs, benzene, toluene, and pyridine, including its
derivatives. In September 1993, a record of decision (ROD) was signed for operable unit (OU) 2 to address the
contaminated soil and sludge in the disposal areas. The ROD required treatment of 11,000 tons of soil on site using
thermal desorption. An explanation of significant differences (BSD) was signed in October 1997 to modify the remedy for
OU 2, reducing the quantity of soil to be treated to 3,700 tons

The thermal treatment system used for this application was a low temperature thermal desorption system owned by
Williams Environmental Services, Inc. Between November 1996 and January 1997, a total of 3,700 tons of contaminated soil
were treated. The presence of elevated BTU and moisture content of the soil limited the amount of material that could be
processed through  the desorber.  Engineering modifications, including blending soil, modifying the desorber to promote
heat transfer, and reducing the soil screening cutoff size, did not increase the throughput rate. The vendor was able to
treat only about one-third of the contaminated soil originally intended to be treated on site with thermal desorption
because of this change in site conditions. The remaining contaminated soil  was shipped off site for treatment using a boiler
or industrial furnace. The total costs for the thermal treatment application $1,087,732, ($25 I/ton of soil treated).

located in Area 6 of the Dover AFB in Delaware. Average TCE, DCE, and PCE concentrations in groundwater at Area 6
were 4,800 ug/L, 1,200 ug/L, and 3 ug/L, respectively.

The ISB system used for the demonstration included injection and extraction wells, a nutrient/substrate injection system,
and a groundwater monitoring system. The demonstration, performed between May 1996 and March 1998, included two
phases - one involving the stimulation of indigenous microorganisms; one using bioaugmentation with a culture from
Largo, Florida.  While no degradation beyond DCE was observed during the first phase using indigenous microbes, the
addition of the culture from Florida resulted in the complete degradation of solvents to ethene. Costs to perform ISB at
Dover AFB were based on the cost of the demonstration.  The estimated net present value of implementing ISB at Dover
AFB was $596,000. Better mechanisms for effective distribution of nutrients and substrate into low permeability zones of
an aquifer was identified as a future development need to facilitate implementation of ISB.

        Enhanced In Situ Bioremediation at Idaho National Engineering and
   Environmental Laboratory, Test Area North, Idaho Falls, Idaho (continued)
Description:
At the Test Area North (TAN) at INEEL, liquid wastes containing solvents and radionuclides were injected into an aquifer
between 1953 and 1972, resulting in groundwater contamination at the site. TCE, PCE, and 1,2-DCE and radionuclides are
present in the groundwater, and the contaminant plume is about two-miles ling and 200 to 450 ft deep.

In 1999, a demonstration of ISB was initiated at the TAN site to treat the source area of the contaminant plume and the
more dilute dissolved plume with natural attenuation.  Sodium lactate was injected into the subsurface using one injection
well and extracted using one well located downgradient of the source to create a treatment cell about 492 ft long. After a
one-year period, TCE concentrations in a number of wells were reduced to non-detectable levels and evidence of natural
attenuation was observed in the dissolved plume.  The system was continuing to operate through 2001.  According to
DOE, the technical applicability of ISB is dependent upon site geology, concentrations of native nutrients, and the natural
oxidation potential of the subsurface.

Description:
The ITTNV plant in Roanoke, VA is an active manufacturing plant that produces night vision devices and related
products. Groundwater contamination resulted from tank leaks of chlorinated and nonchlorinated compounds used as
manufacturing cleaning solvents. The contaminated area included groundwater in fractured bedrock.

Of the four contaminants analyzed, two (cis-1,2-DCE and VC) met the treatment goal of 75% reduction (with a 0.1 level of
significance) in the zone of influence. The demonstration was originally intended to last 6 months, but process
optimization and modifications resulted in extending the evaluation period to 16 months.

Description:
In situ bioremediation was conducted at six drycleaner sites contaminated with chlorinated solvents from drycleaning
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 1,230 mg/L and TCE in groundwater as high as
8.3 mg/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 HRCฎ at five sites and molasses at one site. The injection wells were installed
using direct push techniques, and the concentrations of TCE and PCE were monitored after the application of the
technology.  A single injection of HRCฎ was performed at the five sites. Reductions in PCE and TCE concentrations and
increases in PCE and TCE biodegradation products were reported for all five sites. At one site, molasses was injected 6
times over a period of 20  months. PCE concentrations in groundwater decreased to below analytical detection limits and
the site was closed.

• Test area was 20 feet wide by 30 feet long and 20 feet deep
• Solution consisted of a surfactant, calcium chloride, isopropyl alcohol, and
  water was injected through 3 injection wells at a rate of 0.133 gallons per
  minute (gpm) per well for 58 days; six extraction wells removed subsurface
  liquids at a combined rate of 1 gpm
• Above-ground treatment included gravity separation to remove separate
  phase DNAPLs, pervaporation to remove dissolved-phase contaminants, and
  ultrafiltration (UF) to reconcentrate surfactant fluid prior to reinjection
• Surfactant flush was followed by a 74 day water flush to remove injected
  chemicals and solubilized or mobilized contaminants
• Partitioning interwell tracer test (PITT) to demonstrate DNAPL removal and

Results:
• A total of 76 gal of PCE were recovered during the demonstration with 32 gal recovered as solubilized DNAPL and 44
  gal as free-phase DNAPL
• DNAPL was effectively removed from the more permeable layer (above 17.5 ft bgs) with DNAPL remaining in the lower
  permeability basal silt layer; DNAPL recovery in more permeable layer -at a rate of 92%-96%; DNAPL recovery from
  entire test zone (both layers) - 72%; the poor sweep of the surfactants across the lower portion of the contaminated
  zone was attributed primarily to the permeability contracts between the two zones
• Above-ground treatment system removed > 95% of extracted PCE; surfactant recovery - 77%; injected isopropyl alcohol
  recovery - 88%
Costs:
• Total demonstration costs were $3.1 million, including DNAPL source zone characterization, surfactant selection, well
  field installation, free-phase DNAPL removal equipment, pre-treatment PITT, application of the technology, surfactant
  regeneration, and indirect costs
• Estimated total costs for full-scale systems were estimated at $1.5 million to treat a 2,500 square foot area, $6.8 million to
  treat a 0.5 acre area, and $12.8 million to treat a 1 acre area.
Description:
Marine Corps Base Camp Lejeune, Site 88, Building 25 is the location of a central dry cleaning facility. The site is
contaminated with PCE and Varsol™, a petroleum distillate from storage and use during drycleaning operations. PCE is
present in groundwater at the site as DNAPL. Varsol™ is present as LNAPL. A demonstration of the surfactant-enhanced
aquifer remediation system (SEAR) was performed by the U.S. Department of Defense Environmental Security Technology
Certification Program (ESTCP), targeted at treating DNAPL in groundwater.

Injection of a solution of surfactant, isopropyl alcohol, and calcium chloride was conducted for 58 days, followed by a 78-
day water flushing to remove mobilized contaminants and residual flushing solution. DNAPL was effectively removed
from the more permeable layer (above 17.5 ft bgs) with DNAPL remaining in the lower permeability basal silt layer. The
results of the demonstration showed that aquifer heterogeneity has a strong influence on the performance of SEAR and
the sensitivity of the technology to permeability contrasts indicated the importance of performing a thorough DNAPL
source zone characterization.

  a custom surfactant (Alfoterra 145-4-PO sulfate™), 38,637 Ib isopropanol and 427 Ib calcium chloride.
  Extraction wells recovered the injected solution and groundwater, and 19% (1,800 Ib) of the total
  surfactant injected was recycled.
• At the Former Sages Drycleaner site, treatment consisted of injecting 9,000 gallons of a 95% ethanol
  and 5% water mixture through 3 injection wells.  Injected fluids and groundwater were recovered
  through 6 extraction wells. Cosolvent fluid was injected at a rate of 4 gpm. The extraction rate was 8
  gpm.  The extracted  mixture of PCE, ethanol, and water was treated with the Akzo Nobel Macro
  Porous Polymer (MPP) system for removal of PCE. Approximately 160,000 gallons of an ethanol and
  water mixture was disposed of off-site.
Thermally enhanced SVE
• At the Cedarburg Drycleaners site, in situ thermal desorption was used to treat contaminated soil.
  The treatment process used a chain trencher to break up and pulverize the soil matrix while hot air at
  temperatures up to 700ฐF was forced into the trench. Vapors from the process were collected using a
  vacuum hood.  In addition, groundwater was treated at this site using bioremediation, which was
  performed by injecting a dilute molasses solution to enhance microbial activity that would result in a
  reductive dechlorination of chlorinated contaminants.
In-well air stripping
• At the Former Nu Look  One Hour Cleaners site, a single pilot recirculating well using in-well airlift
  through a 12-ft stripping column was operated for a period of 30 days. Air was introduced through a
  diffuser at an average rate of 35 cfm. and 5 psig.  The vapor stream extracted from the wellhead was
  recycled through a carbon treatment system and reused in the airlift stripping column. This minimized
  the injection of oxygen into the well, which helped maintain an anaerobic subsurface environment.

  In Situ Treatment Using Cosolvent Flushing, Thermally Desorption, or In-Well
                    Air Stripping at Four Drycleaner Sites (continued)
Type/Quantity of Media Treated:
• Groundwater plume areas ranged from 0.27 to 17 acres.  The deepest reported plume went to 92 feet below ground
  surface. Actual treatment areas ranged from 6,000 to 150,000 cubic feet for groundwater treatments.  At the Cedarburg
  Dry cleaners site, the 100 cubic feet of soil were treated.
Regulatory Requirements/Cleanup Goals:
The Cedarburg Dry cleaners site reported a cleanup goal of less than 6 mg/kg PCE in soil based on state requirements.
Cleanup goals for the other sites were not reported.
Results:
• At the Building 25, Camp Lejeune Marine Corps Base site, 72% (74 - 88 gallons) of the DNAPL in the treatment zone
  were removed. However, DNAPL was not removed from low permeability areas of the treatment zone. Test results
  indicated that the technology is not effective for soils with a permeability of less than 1.4 feet per day.
• At the Cedarburg Drycleaners site, soil PCE concentrations were reduced to below 0.4 mg/kg. However, treatment was
  limited because the unit used could not penetrate deep enough to reach all contamination.
• At the Former Nu Look One Hour Cleaners site, a 75% reduction in volatile organic compounds was achieved in a 62-
  foot radius around the in-well air stripping unit.  Slight rebounds of PCE were observed 6 months after completion of the
  demonstration.
• At the Former Sages Drycleaners site, 63% (11 gallons) of the DNAPL in the treatment zone were removed. Residual
  ethanol remaining  after the flushing process reportedly enhanced biodegradation of chlorinated compounds.
Costs:
Reported costs:
• Building 25, Camp Lejeune Marine Corps Base - Not reported
• Cedarburg Drycleaners design and implementation costs - $48,000 for soil treatment, $44,000 for groundwater treatment

  was granular activated carbon followed by discharge to an on-site wastewater
  treatment plant. Extracted soil gas was also treated using granular activated
  carbon followed by release to the atmosphere .
• Demonstration was conducted in extraction only mode, and
  extraction/injection mode. During extraction only test, the groundwater
  extraction rate ranged from 25 to 150 gallons per hour and the soil gas
  extraction rate ranged from 120 to 350 standard cubic feet per minute. The
  system was operated in extraction only mode for 6 hours per day over a
  period of 23 days.  During extraction/injection test, 120 gallons per hour of
  water were injected and an equal amount extracted over a 50 hour period.

Well Injection Depth Extraction (WIDE) Soil and Groundwater Flushing at RMI
                        Titanium Plant, Ashtabula, Ohio (continued)
Results:
• Groundwater monitoring data over eight months following demonstration indicated TCE concentration reductions
  ranged from 46% to 57%.
• The TCE and U extraction rates (including contaminants extracted from both groundwater and soil vapor) for the
  extraction only test were 2,800 mg/hour and 420 mg/hour respectively.
• The TCE and U extraction rates (including contaminants extracted from both groundwater and soil vapor) for the
  extraction/injection test were 1,300 mg/hour and 640 mg/hour respectively.
Costs:
• The demonstration program had a capital cost of $386,000 and estimated annual O&M cost (the demonstration was
  performed in 8 months) of $200,000.
• The estimated costs of treating the entire 1.25 acre TCE groundwater plume were $1.3 million capital cost and $0.2 million
  annual cost over a treatment time of 5 years to meet the O.005 mg/L cleanup goal for TCE.
Description:
The RMI Titanium Plant is a former uranium processing facility which supplied extruded an milled uranium products for use
within DOE's weapons complex. A former evaporation pond is responsible for the TCE and U contamination of
groundwater at the site.  DOE's Office of Science and Technology, in coordination with AEMP, conducted a demonstration
of soil flushing at this site.

The soil and groundwater flushing system was tested in several modes of operation over a period of eight months on a 70
foot by 70 foot area covering the former evaporation pond. The technology was tested in extraction only and
extraction/injection mode. Eight months after the test, TCE concentrations in the groundwater were reduced from 46% to
57%.

    In-Well Vapor Stripping Technology at Brookhaven National Laboratory,
                                 Upton, New York (continued)
Description:
At the DOE Brookhaven National Laboratory (BNL) in Upton, New York, groundwater is contaminated by various
chlorinated organic compounds to depth ranging from 150 to 230 ft below surface. BNL is situated over a sole-source
aquifer and was placed on the National Priorities List in 1989. DOE is remediating the site under a Federal Facilities
Agreement, including OU 111, a groundwater plume originating near the south central portion of the site and extending
beyond the sites boundaries.  The groundwater plume is located within a complex glacial aquifer.

In September 1999, DOE began a demonstration of in-well vapor stripping  technology at OU 111 using the patented UVB
system from lEG-Technologies Corporation. Seven UVB wells, each equipped with an air stripper, were installed along the
plume. As of March 2001, 300 pounds of VOCs have been removed and more that 278 million gallons of groundwater have
been treated.  The system is continuing to operate. According to DOE, the technical applicability of in well vapor
stripping is dependent upon the hydrogeological properties of the saturated and unsaturated zones, the geochemistry of
the aquifer, and the contaminants at the site.

Technology:
UVB recirculating wells (with air stripping)
• UVB uses an in-well stripping platform, operated under negative pressure,
  with a four-screen design
• Two UVB wells were used; pumps operated at 39 to 61 gpm; the air stripping
  unit used an air to water ratio ranging from 120:1 to 150:1
• Air treatment consisted of GAG

NoVOCs recirculating wells (with air stripping)
• NoVOCs uses a double-cased, in-well vapor-stripping system; pressurized air-
  lift pumping is used to extract water through screens located at the base of
  the plume; VOCs are stripped and filtered through GAC; treated water is
  reinjected
• Two NoVOCs wells were used; pumps operated at  160 gpm for one well and
  140 gpm for the other
• 24 monitoring wells (8 clusters of 3 each) were used to monitor the
  groundwater at each test site

                                     •  Three hydrostratigraphic zones were identified beneath the test sites - upper,
                                       middle, and lower

• The pilot tests were conducted to assess the overall feasibility of using recirculating well technology to achieve
  "significant contaminant reduction" (not further quantified)
• A performance standard was established as 1 ug/L for TCE in the discharge from the air stripper, with TCE used as a
  measure of total VOCs in the water

Results:
•  The cumulative mass of TCE removed by the UVB wells during the pilot test was about 18 kg; TCE concentrations in
   the groundwater were reduced in the upper and lower hydrostratigraphic zones, and remained relatively stable in the
   middle zone
•  The cumulative mass of TCE removed by the NoVOCs wells during the pilot test was about 43 kg; TCE concentrations
   in the groundwater remained stable
•  The pilot study and continued operation indicated that recirculating well technology reduced concentrations of TCE,
   PCE, and 1,2-DCE; however, a comparison of the two technologies in terms of contaminant reduction could not be made
   from the available data for several reasons
Costs:
•  The actual cost for the CS-10 recirculating well pilot test and subsequent operational period was approximately
   $3,000,000, consisting primarily of costs for drilling ($1,583,000) sampling ($635,000), and construction ($554,000).
•  Information was not provided about the projected cost for a full-scale treatment system.
Description:
MMR is a military training facility located in the upper western portion of Cape Cod, Massachusetts, about 60 miles
southeast of Boston.  Leaks and spills from historical operations including vehicle maintenance and repair, parts cleaning,
and painting; storage of petroleum products and hazardous materials; and disposal of wastes in landfills resulted in soil
and groundwater contamination. A Technical Review and Evaluation Team recommended that pilot-scale testing of
recirculating well technology be performed in the southeastern area of the CS-10 plume within the industrial area to
evaluate the effectiveness of this innovative technology for reducing concentrations of contaminants in the groundwater.
The pilot testing was performed prior to installation of a groundwater extraction system, identified as the interim remedy for
CS-10 groundwater the ROD signed in September 1995.

During the pilot test, the cumulative mass of TCE removed by the UVB wells was about 18 kg and about 43 kg for the
NoVOCs system. According to the prime contractor at the site, the results of the pilot tests indicate that recirculating well
system hydraulics are more sensitive to site-specific hydrogeologic conditions than extraction, treatment, and reinjection.
In addition, modeling results indicated that the presence of low hydraulic conductivity layers can inhibit the establishment
of effective recirculation wells.

Cleanup Type:
Field demonstration
Waste Source:
Wastes from various operations at the
base
Technology:
In-well air stripping
• The system consisted of a single well casing installed into the contaminated
saturated zone, with two screened intervals below the groundwater table, and
an air injection line extending into the groundwater within the well. The
stripped VOC vapors were removed by a vacuum applied to the upper well
casing and treated using a flameless oxidation process.
• The recharge screen was located in the saturated zone, rather than the usual
location in the vadose zone, because of the presence of a hydraulic barrier
between the vadose zone and the intake screen, which could adversely affect
the groundwater circulation through the system.
• Effluent air flow rate from the well ranged from 50 to 69 scfm.
Type/Quantity of Media Treated:
Groundwater
Regulatory Requirements/Cleanup Goals:
• Objectives of demonstration included assessing the technology's ability to treat groundwater contaminated with high
levels of chlorinated VOCs
Results:
• Total estimated VOC removed during demonstration - 92.5 pounds; average total VOC mass removed ranged from 0.01
to 0. 14 pounds per hour
• The mean concentrations of contaminants in the treated water discharged from the system: 1,1 DCE - 27 ng/L, cis-1,2-
DCE - 1,400 ng/L, and TCE - 32 ng/L
• Measurable pressure changes occurred at crossgradient locations 30 feet from the well
• Fouling from iron precipitation and biological growth occurred, reducing pumping rates significantly. Iron precipitation
was reduced by adding citric acid, but biological fouling was not successfully controlled.
Costs:
• Projected capital costs for a full-scale single system - $190,000; projected annual O&M costs - $160,000 the first year,
and $150,000 per year thereafter

A demonstration of in-well air stripping was performed at the NAS North Island, Installation Restoration Site 9 to assess
the technology's ability to treat groundwater contaminated with high levels of chlorinated VOCs. The project was
conducted under EPA's Superfund Innovative Technology Evaluation (SITE) program in conjunction with EPA's
Technology innovation office, Naval Facilities Engineering Command Southwest Division (SWDIV), Navy Environmental
Leadership Program, and Clean Sites, Inc.

During the demonstration, in-well air stripping removed an estimated 92.5 pounds of VOCs. The remediation at this site
was challenging because the groundwater contained total dissolved solids (TDS) concentrations ranging from 18,000 to
41,000 mg/L, which are higher than those typically found in drinking water aquifers.  Operational difficulties associated
with biofouling and the precipitation of iron resulted in an incomplete evaluation of the technology.

     Permeable Reactive Barriers (PRBs) Using Iron with a Bulking Agent as a
                       Reactive Media, Various Locations (continued)
Costs:
Installation cost information was available for four of the eight projects in the case study (F.E. Warren Air Force Base -
$2,400,000, Seneca Army Depot - $350,000,  Somersworth Sanitary Landfill - $2,000,000, Watervliet Arsenal - $278,000).
Description:
This report provides an interim summary of information about eight projects (seven full-scale and one pilot-scale)
involving the application of PRB technologies where iron with a bulking agent was used as a reactive media for the
treatment of groundwater contaminated with chlorinated solvents, other organic contaminants, and/or inorganic
contaminants.

Lessons learned at the PRB sites summarized in this report include those related to specific successes and issues
associated with installing various configurations using iron with a bulking agent, and the suitability of these bulking
agents  for addressing contamination at specific sites.  Bulking agents have been combined with iron for several reasons,
including improving groundwater flow conditions within the reactive zone, treatment of additional contaminants not
addressed by iron alone, and reducing project cost.

Technology:
PRBs
• Two PRBs installed to intercept two pathways of the shallow groundwater
  contaminant plume - funnel-and-gate PRB (FGPRB) and trench PRB (TPRB)
• FGPRB
  - Sand-filled collection trench that is 220 ft long and 25 ft deep- two wing walls
  used to funnel groundwater to treatment zone; collection side and discharge
  side separated by a HOPE impermeable barrier installed vertically in middle of
  the trench
  - Two treatment systems demonstrated; (1) treatment train of three 55-gal
  canisters run in series - pH adjustment using magnesium hydroxide, iron and
  gravel; ZVI for uranium removal; iron and peat mixture for nitrate removal; (2)
  electrochemical cell - one 55-gal drum equipped with electrodes at the top and
  bottom and filled with ZVI; applied current used to increase groundwater pH
  to increase reductive capacity of the iron
  - Buildup of hydraulic head in discharge portion of PRB required installation
  of pumps in the treatment area to move groundwater through the system
• TPRB
  - 225 long and 30 ft deep  groundwater capture trench installed subparallel to
  groundwater flow with an impermeable barrier on downgradient side of the
  trench; groundwater flows through a  section of reactive iron media in the
  middle of the trench (26ft long by 2 ft wide by 30 ft deep) then discharged
  through gravel backfill
  - Buildup of hydraulic head in discharge portion of PRB required the trench to
  be extended and an enhancement zone to be constructed to provide sufficient
  gradient to overcome the hydraulic buildup
                                     Type/Quantity of Media Treated:
                                     Groundwater
                                     • Shallow groundwater - unconsolidated zone; relatively low hydraulic gradient
                                     • Deep groundwater - bedrock
                                     • Soil is 20-30 ft thick; relatively low permeability except at transition zone
                                       (weathered and fractured bedrock between soil and competent bedrock)
                                     FGPRB -  133,000 gal of groundwater treated
                                     TPRB - 200,000 to 400,000 gal of groundwater treated

              Passive Reactive Barrier at Oak Ridge National Laboratory,
                               Oak Ridge, Tennessee (continued)
Regulatory Requirements/Cleanup Goals:
• The objective of the demonstrations were to reduce the amount of contaminant reaching Bear Creek through the two
  pathways in the shallow groundwater
• No specific cleanup levels identified for the demonstration
Results:
• FGPRB
  - Uranium concentrations in groundwater reduced 80 to 99.6%
  - Reduction of secondary contaminants 75% for nitrate and 42% for sulfate
• TPRB
  - Uranium concentrations in groundwater reduced about 90%
  - Reduction of secondary contaminants highly variable
• Low hydraulic gradient and recharge from the deep aquifer affected the performance of the PRBs by causing buildup of
  hydraulic head on the downgradient side of the trenches adversely impacted the hydraulic operation and treatment
  effectiveness of the systems
Costs:
• Actual installation costs for the FGPRB demonstration were $943,000; costs for long term O&M are under development
• Costs for the TPRB had not been fully developed and were therefore not included in the report
Description:
The S-3 Ponds at the Oak Ridge National Laboratory, Oak Ridge Reservation Y-12 Plant in Oak Ridge, Tennessee were
used for the disposal of uranium-contaminated waste. These waste disposal activities resulted in three contaminant
migration pathways at the site - two in the shallow groundwater and one in the deep groundwater. Demonstrations of two
PRB systems were conducted at the site to treat the two contaminant pathways from the shallow groundwater. Uranium
concentrations in the shallow groundwater ranged as high as 1.7 mg/L to 2.6 mg/L.

The two technologies demonstrated were FGPRB and TPRB, using reactive iron as the treatment media. Data from two
years of operation (August 1997 to August 1999) show that uranium concentrations in groundwater were reduced by as
much as 96.6% by the FGPRB and 90% by the TPRB.  During this time, the FGPRB treated about 133,000 gallons of
groundwater and the TPRB treated between 200,000 and 400,000 gallons of groundwater.  During the demonstrations,
buildup of hydraulic head on the downgradient side of the trenches adversely impacted the hydraulic operation and
treatment effectiveness of the systems and system modifications were performed to address the problem. The systems are
continuing to operate.

Technology:
Phytoremediation
Demonstration area is approximately 2,034 m2 and contains 156 viable poplars
Two-year-old hybrid poplars were planted 5 to 6 ft in Spring 1996; surficial
drainage was installed to remove precipitation quickly and allowed trees to reach
groundwater

Regulatory Requirements/Cleanup Goals:
Provide hydraulic influence of the groundwater plume and mass removal of contaminants; no quantitative cleanup goals
were identified
Results:
Sampling was performed for groundwater; sap flow monitoring; tree transpiration gas and condensate sampling; and
exposure pathway assessments
Groundwater level data indicated that hydraulic influence is occurring, with the trees currently removing 1,091 gpd and at
the end of 30 years expected to remove 1,999 gpd
Contaminated plume has not migrated off-site during the growing seasons
Contaminant uptake is minimal at this time but expected to improve as the trees mature
Costs:
Capital costs of $80/tree including $5,000 for initial site preparation, additional $80,000 for UXO clearance of soil during
planting; O&M costs: $30,000

  Phytoremediation at Aberdeen Proving Grounds, Edgewood Area J-Field Site,
                                    Edgewood, MD (continued)
Description:
Aberdeen Proving Grounds is located at the tip of the Gunpowder Neck Peninsula in Edgewood Maryland. At APG, the
Army practiced open trench (toxic pits) open burning/detonation of munitions containing chemical agents and dunnage
from the 1940s to the 1970s. Large quantities of decontaminating agents containing solvents were used during the
operation, and the surficial groundwater table was contaminated with solvents (1,1,2,2-TCA, TCE, DCE) at levels up to 260
ppm. A demonstration of phytoremediation to clean up shallow groundwater was performed at the site was performed by
the U.S. Air Force (USAF) as part of the Department of Defense's (DOD's) Environmental Security Technology
Certification Program (ESTCP), and the SITE Program.

At the APG site, a process called deep rooting was used to achieve hydraulic influence. Hybrid poplar trees were planted
in the spring of 1996 at five to six feet bgs to maximize groundwater uptake. The field demonstration and evaluation will be
for a five year period. The U.S. Geological Survey has estimated that hydraulic influence will occur when 7,000 gallons of
water per day are removed from the site.  The latest field data indicates that hydraulic influence is occurring. Current tree
uptake is 1,091 gpd and is expected to increase to 1,999 gpd at the end of 30 years. Contaminant uptake is minimal at this
time but is expected to improve as the trees mature. Groundwater sampling indicates that the contaminated plume has not
migrated off-site during the growing season and sampling data showed non-detectable emissions from transpiration gas.
There are several on-going studies to determine if deleterious compounds retained in the leaves and soil could pose risks
to environmental receptors. Cost for site preparation included additional costs for UXO clearance, for a total of $80/tree,
with O&M costs of $30,000 per year.

• In April 1 996, 660 eastern cottonwoods were planted in a one acre area
• Two sizes of trees were planted - whips and 5-gallon buckets
Type/Quantity of Media Treated:
Groundwater
• Shallow (under 12 ft) aerobic aquifer
Regulatory Requirements/Cleanup Goals:
- Provide hydraulic containment and removal of contaminants
- Reduce mass of TCE in the aquifer transported across the downgradient end of the site by 30 % during the second
growing season and by 50 % during the third growing season, as compared to baseline TCE mass flux calculations
Results:
• Root biomass and extent were examined in September of 1997 (the second growing season)
• In September 1997, the roots of both the whips and caliper trees had reached the water table and the depth distribution
  of the roots was similar
• The maximum reduction in the outflow of contaminated groundwater that could be attributed to the trees was
  approximately 11 %, and was observed at the peak of the third growing season
• Preliminary field data collected during the fifth dormant season (January 2001) indicate that the trees were beginning to
  have a widespread effect on groundwater geochemistry, reducing dissolved oxygen content beneath the trees to less
  than 1 mg/L
Costs:
The total cost for site preparation was $22,000, site work $171,200, and annual O&M $2,000, in addition to costs for
research level monitoring.

     Phytoremediation at Carswell Air Force Base, Fort Worth, TX (continued)
Description:
Groundwater at the U.S. Air Force Plant 4 (AFP4) and adjacent Naval Air Station, Fort Worth, Texas, has been
contaminated with chlorinated solvents from operations associated with the manufacture and assembly of military aircraft. .
A demonstration of phytoremediation to clean up shallow groundwater was performed at the site was performed by the
U.S. Air Force (USAF) as part of the Department of Defense's (DOD's) Environmental Security Technology Certification
Program (ESTCP), and the SITE Program.

The first three growing seasons at Carswell resulted in a remediation system that reduced the mass of contaminants
moving through the site. The maximum observed reduction in the mass flux of TCE across the downgradient end of the site
during the demonstration period was 11 percent. Increases in hydraulic influence and reductive dechlorination of the
dissolved TCE plume are expected in out years, and may significantly reduce the mass of contaminants. Modeling results
indicate that hydraulic influence alone may reduce the volume of contaminated groundwater that moves offsite by up to 30
percent. The decrease in mass flux that can be attributed to in situ reductive dechlorination has yet to be quantified. The
total cost for site preparation was $22,000, site work $171,200, and annual O&M $2,000, in addition to costs for research
level monitoring.

        Phytoremediation at Edward Sears Site, New Gretna, NJ (continued)
Description:
From the mid-1960s to the early 1990s, the Edward Sears property was used for the repackaging and sale of paints,
adhesives, paint thinners, and various military surplus materials. The soil and groundwater were contaminated with a
variety of contaminants, including dichloromethane, PCE, TCE, TMB, and xylenes.  A demonstration of phytoremediation
to clean up shallow groundwater was performed at the site was performed by the U. S. Air Force (USAF) as part of the
Department of Defense's (DOD's) Environmental Security Technology Certification Program (ESTCP), and the SITE
Program.

At the Edward Sears site, a process called deep rooting was used to achieve hydraulic influence. Hybrid poplar trees were
planted in late 1996 at 9 ft bgs in a plot of one-third acre, with performance measured for 3 years (a fourth year of
monitoring is planned). There were substantial reductions in dichloromethane and TMB concentrations during the 1998
growing season. For example, dichloromethane was reduced to 615 parts per billion (ppb) from 490,000 ppb at one location
and to a non-detect level from up to 12,000 ppb at another location; TMB was reduced to 50 ppb from 1,900 at one location.
There is also indication of anaerobic dechlorination in the root zone as the level of PCE dropped and TCE increased.  The
total cost for installation was $105,000, consisting of $24,000 for site preparation, $65,700 for planting; and $15,300 for
maintenance. Groundwater monitoring will continue into 2002.

      Soil Vapor Extraction (SVE) and Air Sparging at Four Drycleaner Sites,
                                 Various Locations (continued)
Results:
Alpine Cleaners - The PCE groundwater plume continued to spread, although at a slow rate. PCE concentrations
exceeded the treatment goal of less than 0.003 mg/L in several monitoring wells. The remediation system removed
approximately 390 pounds of VOCs during 5 years of operation. The removal of VOCs leveled off after approximately 2
years of operation.
Dry Clean USA #11401 - Approximately 23.7 pounds of contaminants were removed from the subsurface. Total
chlorinated ethylene concentrations in shallow- and intermediate-depth source area monitoring wells decreased by 2-3
orders of magnitude. However, cis-l,2-DCE concentrations rose two orders of magnitude in the deep-source area
monitoring well. Five wells still contained contaminant concentrations exceeding MCLs.
Former American Uniform - The SVE system achieved cleanup goals to remediate the source area vadose zone.
Significant reductions in the concentrations of chlorinated VOCs in the groundwater were observed, including a decrease
in PCE concentrations.  However, rebounding PCE concentrations were observed 6-months after the remediation was
completed. The SVE system removed 221 Ibs of PCE.
One Hour Dry Cleaners -  Through August of 2001, approximately 4 pounds of contaminants were removed from the
subsurface. Contaminant concentrations in source area monitoring wells were reduced two orders of magnitude.
Costs:
Design and implementation costs ranged from $28,000 to $240,000; annual O&M costs ranged from $16,000 to $200,000.
Description:
SVE and air sparging was conducted at four drycleaner sites contaminated with chlorinated organic compounds from leaks,
spills, or dumping of dry cleaning solvents or wastewaters. Although all of the treatment systems removed contaminants
from the subsurface, only one treatment achieved cleanup goals. Reported design and implementation costs ranged from
$28,000 to $240,000. Reported annual O&M costs ranged from $16,000 to $200,000.

Technology:
In situ chemical oxidation:
• At the Butler Cleaners #1, Butler Cleaners #2, and Former Quick-N-Easy Wash-O-Mat and Former
  Artistic Cleaners sites, solutions of potassium permanganate were injected into the subsurface to
  oxidize contaminants. At two sites the solutions were mixtures of potassium permanganate with
  water, with potassium permanganate making up 8% to 15% of the solution.  At one site, the
  solution was heated and tertiary butyl alcohol was added to help mobilize the contaminants. The
  solutions were injected through from one to 45 wells, and injection volumes ranged from 1,000 to
  2,200 gallons. At two of the sites S VE was also used to remove contaminants  from the soil.
• At the Hanner's Cleaners and Swift Cleaners sites, solutions of water, hydrogen peroxide (12 to
  25%), and an unspecified catalyst were injected into the subsurface to oxidize contaminants.  The
  solutions were injected through from 6 to  12 wells, and volumes ranged from 1,700 to 20,000
  gallons. SVE was also used at both sites to remove contaminants from the soil.
• At the Paul's Classic Dry Cleaners site, a field demonstration of an ozone in-well air sparging
  system was conducted.  The treatment system consisted of a single well where sequential
  sparging and  groundwater recirculation functions were performed in the sparge well. The system
  delivered an air and ozone gas mixture (the composition of the mixture was not specified) at a rate
  of 1.7 to 2.2 cfm first to the lower sparge point, then the in-well sparge point, each for a specified
  period of time. In-well pumping was then performed.  This process was repeated in a cycle over a
  period of 16-18 hours/day.  Multi-phase extraction was also conducted at the site.

• Groundwater extraction began in November, 1988 using a single well designed
  to yield 500 gallons per minute (gpm). In August 1995, 4 additional wells
  designed to yield 50 gpm each also began extracting groundwater.
• extracted groundwater is treated using two granular activated carbon (GAC)
  adsorption vessels connected in series, each of which contain about 20,000
  pounds of GAC.
Soil Vapor Extraction (SVE)
• The SVE system consisted of 23 vapor extraction wells in the vadose zone
  and a carbon adsorption system to treat the vapors.
• The design air flow rate for the system was 3,000 standard cubic feet per
  minute.
• The SVE system operated between Augustl993 and May 1997.

   Pump and Treat and  Soil Vapor Extraction at the Commencement Bay South
              Tacoma Channel Superfund Site, Tacoma, WA (continued)
Results:
• Actual groundwater extraction rate is less than 100 gpm. Iron fouling likely is a primary cause of the low extraction rate.
• About 15,000 pounds of VOCs had been removed from groundwater by the pump and treat system through December
  2000.
• As of June 2000, concentrations of PCA, TCE, and total-1,2-DCE in the extraction wells remained above the remedial
  goals. Information on the concentrations of other contaminants were not provided.
• The size of the TCE and DCE contaminant plumes have decreased from 1993 to 1998.
• The above ground treatment system routinely met performance  standards.
• The RPM indicated that the current pump and treat system will  not attain the aquifer remedial goals due to the presence
  of light and dense non-aqueous phase liquids.
• The SVE system removed approximately 54,100 pounds of VOCs from subsurface soils at the site.
Costs:
Pump and Treat System:
• Total capital costs through May, 2000 were $1.8 million
• Total year 2000 operating costs were $0.41 million
Cost information was not provided for the SVE system.
Description:
From the 1920s to 1976 site operations included oil recycling and manufacturing of thinner for paint and lacquer. From
1976 to 1995, site operations were limited to canning new oil brought to the site in bulk containers. The facility has been
used as a warehouse for heating, ventilation, and air conditioning equipment since 1995. Both shallow soil, subsurface
soil, and groundwater at the site were contaminated with volatile organic compounds (VOCs), including chlorinated
solvents.

SVE was used from 1993 to 1997 to treat soil at the site. A pump and treat system for groundwater was installed and began
operating in 1988. Operation of the pump and treat system was ongoing as of June, 2000. Through December 2000, the
pump and treat system had removed about 15,000 pounds of VOCs, and the SVE system had removed another 54,100
pounds of VOCs during its operation. However, the presence of light and dense non-aqueous phase liquids provide
continuing sources of dissolved phase contaminants, and remedial goals for the aquifer are not expected to be met using
pump and treat. Future plans for the site are being evaluated to determine the optimal approach to address site-related
contamination.

Technology:
Pump and Treat of Groundwater:
• The groundwater extraction system consists of 28 wells, all screened in the
  shallow aquifer.
• The above-ground treatment system consists of: metals removal using
  precipitation; organics removal using air stripping, UV/oxidation, and granular
  activated carbon; and discharge of treated water to a nearby stream.
• Vapors from the water treatment units and the soil vapor extraction (SVE) unit
  treated with thermal oxidation prior to discharge to the atmosphere
• The groundwater monitoring network includes 109 wells. For each monitoring
  event, only approximately 20 wells were sampled and analyzed. From January
  1996 through April 1998, the groundwater was monitored quarterly. After
  April 1998, groundwater monitoring was performed  semi-annually.
Soil Vapor Extraction
• 91 hot air injection wells heat soils and increase volatilization
• 33 vapor  extraction wells
• pump-and treat system and clay cap enhanced SVE by dewatering soils and
  minimizing discharge of surface water into the subsurface
• thermal oxidation of vapors from the water treatment units and the soil vapor
  extraction (SVE) unit prior to discharge to the atmosphere
In Situ Chemical Oxidation
• Injection  of potassium permanganate in a two percent solution and sodium
  permanganate in a 20 to 40 % solution using existing groundwater extraction
  and monitoring wells
                                    Type/Quantity of Media Treated:
                                    Groundwater
                                    •  8.4 million gallons of groundwater treated (January 1996 through December
                                       1999)
                                    •  Shallow and bedrock aquifer systems
                                    •  48,000 cubic yards of soil treated

  Pump and Treat, In Situ Chemical Oxidation, and Soil Vapor Extraction at the
      Union Chemical Company Superfund Site, South Hope, ME (continued)
Regulatory Requirements/Cleanup Goals:
• Groundwater extraction rate of 5.1 gallons per minute
• 1,1 -Dichloroethane (DCA) - 5 ng/L (groundwater), 0.5 ng/L (pump-and treat system discharge)
• Trichloroehtene (TCE) - 5 ng/L (groundwater), 0.5 ng/L (pump-and treat system discharge)
• 1,1-Dichloroethene (DCE) - 7 ng/L (groundwater), 0.5 ng/L (pump-and treat system discharge)
• 1,1,1-Trichloroethane (TCA) - 200 ng/L (groundwater), 0.5 ng/L (pump-and treat system discharge)
Results:
• From January 1996 through June 1999 about 9,600 pounds of VOCs were removed by the P&T and SVE systems
• In general, contaminant concentrations in the groundwater are decreasing over time
• Contaminant concentrations in the effluent from the pump and treat system were not above discharge criteria
• Contaminant mass reductions from chemical oxidation were estimated at 89% reduction for TCE and 47% reduction for
  1,2-DCE, but an increase of 1,1-DCA of 79% was also observed
• Ethane concentrations are decreasing more rapidly than ethene concentrations because the ethenes are responding
  more rapidly to the permanganate additions
Costs:
• Total capital costs for the remediation in 1995 dollars was $9.5 million.
• Average annual O&M costs for the pump and treat and SVE systems was $0.6 million
• Average annual O&M cost for in situ chemical oxidation was $0.15 million
Description:
UCC operated from 1967 to 1986 as a producer and distributor of solvent for the removal of furniture finishes. Operations
were expanded in 1969 to include solvent reclamation and recycling services; these services subsequently developed into
UCCs primary business. Waste treatment operations were discontinued in 1984, at which time MEDEP and EPA removed
from the site 2,000  drums, 30 liquid storage tanks containing 10,000 gallons of liquid waste and sludge, and some
contaminated soil.

On-site soil and groundwater and an off-site stream had been contaminated with VOCs. The pump and treat system began
operating in January 1996 and continued through December 1999. Pumping was resumed on a limited basis from July to
October 2000. SVE was operated at the site since 1996 without any modifications. In October 1997 and June 1998 pilot-
scale tests of in situ chemical oxidation using permanganate were performed at the site. Based on the results of those
tests, in 1999 and 2000 in situ chemical oxidation was used on a ful-scale basis to treat groundwater at the site.

• Demonstration test on 3 x 3 array of 9 nozzle assemblies on reactor face
Regulatory Requirements/Cleanup Goals:
• No specific cleanup goals identified for the demonstration
• Objectives of the demonstration included demonstrating complete coverage over complex shapes and greater
  performance than baseline technology, Rust-Oleum No. 769 coating
• Performance measurements included tests of adhesion, thermal aging, radiation aging, thermal cycling, biodegradation,
  air permaeability, and moisture permeability
Results:
• All three technologies tested (baseline, 1-coat, and 2-coat) passed performance tests for aging resistance
• The baseline technology and 1 -coat processes demonstrated incomplete coverage over complex shapes
• The 2-coat process demonstrated complete coverage, and fast curing at ambient temperatures, but was more expensive
  and required additional labor and training to apply
• The baseline technology and 1-coat system may be applicable to flatter surfaces
Costs:
• Estimated costs to coat the entire reactor face (2,044 nozzle assemblies, 196 square meters) were $64,000 for the 2-coat
  system and $20,900 for the baseline

     Reactor Surface Contaminant Stabilization at the Hanford Site C Reactor,
                                    Richland, WA (continued)
Description:

The Hanford Site produces nuclear material and components for weapons systems.  The demonstration was conducted by
the U.S. Department of Energy's Office of Science and Technology to evaluate their potential to stabilize contaminated
surfaces, such as the face of a nuclear reactor, to avoid airborne contamination during decontamination and
decommissioning activities.

The baseline coating and one-layer coating did not completely cover nozzle assemblies on the reactor face. However, the
two-layer coating system, consisting of a base layer of foam covered by an outer layer of polymeric film, was successful.
The baseline technology would cost about 33% as much as the innovative technology cost of $64,000 to stabilize the
entire Hanford C reactor face, but the baseline system failed to provide complete surface coverage.

Description:
A demonstration of the Lead TechXtractฎ chemical decontamination technology was conducted at DOE's Hanford Site.
Radioactive-contaminated lead bricks from former Reactor C were used for the demonstration.

The Lead TechXtractฎ technology uses ultrasonics and chemical baths to remove radioactive contaminants from surfaces.
Of the 80 bricks treated, 78 met the cleanup criteria that would allow the bricks to be recycled as scrap lead.  The total cost
to treat Hartford's inventory of 1,956 bricks using this technology was estimated to be $49,000. No modifications were
identified as being needed for the technology for use at the Hanford Site C Reactor.  Refinements such as adding a HEPA
filter ventilation system to allow more highly contaminated bricks to be processed were identified.

Surface Treatment - En-Vac Robotic Wall Scabbier
• The system consisted of a robot, a shot recycling unit, a filter, and a vacuum
  unit; capable of cleaning both horizontal and vertical surfaces
• Blast media (abrasive steel grit or steel shot) were provided to the robot
  through the blast hose.  The vacuum unit collected fugitive dust and
  emissions.  Spent blast media and blast residue were returned from the robot
  to the recycling unit through a vacuum hose and the recycling unit separated
  the residue from the blast media.
• Demonstration test area was 60 feet square
Type/Quantity of Media Treated:
Debris
• 60 square feet
Regulatory Requirements/Cleanup Goals:
•  Objectives of the demonstration included evaluating the En-Vac Robotic Wall Scabbier versus the baseline technology
   ofPentekVAC-PAC
•  No cleanup levels were identified for the demonstration
Results:
•  The robotic wall scabbier treated 60 square feet in 36 minutes. The baseline technology treated 45 square feet in 3 hours
   and 15 minutes
•  Compared to the baseline technology, the robotic wall scabbier is heavier and cannot scabble close to obstructions, but
   has a higher treatment rate, and can scabble deeper on concrete.
Costs:
The capital cost of the system was approximately $390,000. Costs for mobilization/demobilization were $2,455, operation,
$37.41 per square foot treated, and waste disposal, $150 per square foot treated.
The robotic wall scabbier was estimated to be less expensive than the baseline technology for projects larger than 1,500
square feet total with average wall sizes greater than 60 square feet.

Description:
Test Area North (TAN) if INEEL supported research into nuclear powered aircraft in the 1950s. Upon termination of this
research, the areas' facilities were converted to support a variety of DOE research projects.  The Decon Shop provided
radiological decontamination of tools and small equipment from 1957 through 1987.

The En-Vac robotic wall scabbier was used to remove lead-based paint from 60 square feet of a concrete surface. The
performance achieved was compared to that of a hand-held scabbling unit using a grinding technology. The robotic wall
scabbier achieved lead-based paint removal in 36 minutes, at an estimated cost of $37.41 per square foot treated, plus
$2,455 for mobilization/demobilization and $150 per square foot treated for disposal of treatment residuals.

Containment - Alternative Landfill Cap
• Soil-based evapotranspiration (ET) cap with engineered structures that limited
  infiltration of precipitation
• Three infiltration designs tested: 20% enhancement of runoff, 40%
  enhancement of runoff, and conventional ET cap (control)
• Rainfall exceeds 25 inches per year at demonstration site
Type/Quantity of Media Treated:
Soil
Regulatory Requirements/Cleanup Goals:
• Purpose of the demonstration was to demonstrate the effectiveness of alternative caps
Results:
• After 16 months of operation, the relative amount of percolation, as a percentage of precipitation, averaged 2 percent for
  the ET cap plus enhanced runoff plots and 5% for the conventional ET cap
Costs:
• Estimated capital costs for ET covers were $50,000 - $100,000 per acre
• Estimated capital costs for ET covers were lover than RCRA C or RCRA D caps and estimated to have lower operation
  and maintenance costs that conventional RCRA caps
Description:
A demonstration was conducted at Marine Corps Base Hawaii, Kaneohe Bay to determine the effectiveness of ET caps as
alternatives to conventional RCRA caps. Three demonstration caps were installed in 1994 - a conventional ET cap to serve
as a control, an ET cap with 20% runoff control, and an ET cap with 40% runoff control. The performance of the designs
were evaluated by comparing the field monitoring data with the predicted performance of the RCRA design using the EPA
HELP model.

After 16 months, percolation rates (as a percentage of precipitation) averaged 5% for the control ET cap, and 2% for the ET
cap plus runoff control plots, supporting the concept of infiltration control by increasing runoff and reducing percolation.
The estimated capital costs for an ET cap were $50,000 - $100,000 per acre, lower than the estimated costs for conventional
RCRA caps.  In addition, the operation and maintenance costs for ET caps was expected to be lower than for conventional
RCRA caps.

Regulatory Requirements/Cleanup Goals:
• No specific cleanup goals were identified for the demonstration
• Objectives of the cover were to contain petroleum vapors and protect against erosion
Results:
•  SOIL-SEMENTฎ coating has been in place since 1997 and is reported to have endured numerous rainstorms and high
   winds without dust or erosion problems
•  SOIL-SEMENTฎ was used to replace a plastic cover that had failed
Costs:
•  Soil-Sementฎ costs for this application were $25,000
•  Estimates to coat a soil pile with Soil-Sementฎ were 4 to 5 cents per square foot of surface area for an inactive pile and 5
   to 12 cents per square foot for an active pile
Description:
Stockpliles of soil at cleanup sites need to be covered to reduce particulate and vapor emissions and to protect against
erosion and runoff. As an alternative to plastic covers, a polymer coating was tested on a soil pile at the Naval Shipyard in
Long Beach CA. The demonstration, conducted by the Naval Facilities Engineering Service Center, in conjunction with
the Naval Facilities South West Division involved testing the Soil-Sementฎ coating on an 11,000 cubic yard soil pile.

The Soil-Sementฎ was sprayed onto the pile and allowed to dry and cure.  The coating has been in place since 1997 and
has been reported to have been effective in controlling dust and erosion from the soil pile. The use of a polymer coating
was found to be cost effective compared to a plastic cover and can be mixed into the soil for disposal.
