The Federal Remediation Technologies
Roundtable (FRTR) promotes interagency
cooperation to further the use of innovative
technologies for remediation of hazardous
waste sites. Primary members of the FRTR
include the U.S. Department of Defense
(DoD), the U.S. Department of Energy
(DOE), the U.S. Department of the Interior
(DOI), the National Aeronautics and Space
Administration (NASA), and the U.S.
Environmental Protection Agency (EPA).
One of FRTR^s priorities is documenting and
distributing information on cost and
performance for completed and ongoing
remediation projects.
The remediation case studies and general
technology assessment reports FRTR
publishes are available at the Web site
www.frfr.gov. These reports provide site-
specific information about treatment and
characterization technologies and long-
term monitoring and optimization, based
on information provided by federal and
state agencies. Site managers,
regulators, technology vendors,

HIGHLIGHT OF NEW REMEDIATION
CASE STUDY
Edible Oil Barriers for Treatment of
Perchlorate-Conta mi noted Groundwater
A permeable reactive barrier (PRB) demonstration
was conducted at a confidential site in Maryland
where groundwater was contaminated with
perchlorate and 1,1,1 -trichloroethane (1,1,1-
TCA], The demonstration evaluated the cost
and effectiveness of an emulsified oil PRB to
control migration of perchlorate plumes. The
demonstration was conducted in October 2003
and consisted of a one-time injection of 1 10
gallons of emulsified oil substrate (EOS) and
2,070 gallons of chase water used to help
distribute the EOS to create a 50-foot-long PRB,
Within 5 days after the oil substrate was injected,
concentrations of perchlorate were less than 4
micrograms per liter (|jg/L) in all of the injection
area wells. In addition, 1,1,1-TCA had been
reduced by more than 90 percent after 1 8
months. Based on these results, it was
determined that all of the primary performance
criteria for the project had been met.

FRTR has added 10 new case studies, for
a total of 384. These case studies on the
cost and performance of remediation
technologies cover a wide range of
technology types and contaminants. Each
report about 10 to 40 pages long)
provides information about the site
background and hydrogeology, a
description of the technology design and
operation, data about cost and
performance, information about lessons
learned from the project, and points of
contact.
three reports address soi cleanup,

MONITORING REPORTS
HIGHLIGHT OF NEW CHARACTERIZATION REPORT
Evaluation of a Former Landfill Site in Fort Collins,
Colorado, Using Ground-Based Optical Remote
Sensing Technology
Pump and treat was implemented at the Fort Lewis Logistics
Center in Washington in 1995 to treat groundwater
contaminated with TCE, DCE, and other halogenated
optimization was conducted for the extraction and treatment
system. Monitoring and Remediation Optimization System
(AAAROS) software developed by the Air Force Center for
Environmental Excellence (AFCEEj was utilized for statistical
analyses and network optimization. A small-scale increase
in the overall number of remedial action monitoring wells
and surface water locations sampled (increase of 20
locations), coupled with a reduction in the frequency at which
result in a significant time and cost savings over the course
of the remedial action monitoring program at the Logistics
Center, In each of the first two years after implementation of
the recommendations set forth in this report, a cost savings
of approximately $31,000 per year is likely to be achieved.

reports cover a full range of site characterization and
monitoring techniques, with many focused on
technologies used in the investigation stage of site
cleanup. A total of 164 characterization and
monitoring reports are available. Exhibit 3 shows
the specific technologies the site characterization and
monitoring reports cover, along with the number of
reports for each technology.
FRTR has added 1 5 new reports on long-term
monitoring and optimization. With this recent addition,
101 long-term monitoring and optimization reports are
now available. Optimization of remediation
technologies consists of using defined approaches to
improve the efficiency of treatment and the cost-
effectiveness of the system. Long-term monitoring
optimization involves identifying and then implementing
strategies and tools to improve the overall effectiveness
and reduce the costs associated with long-term
monitoring programs without compromising quality and
protectiveness. The reports describe long-term
monitoring and optimization efforts that have either been
implemented or evaluated and cover techniques such
as evaluating the groundwater monitoring program and
plume capture, and hydraulic optimization.
FRTR compiles genera technology assessment reports
prepared by federa agencies and the ITRC
{www.itrcweo.org}. As technologies mature, federal
agencies and states are moving beyond documenting
individual projects to providing more comprehensive
analysis of technologies that have been used at
multiple sites. These reports provide a summary of
findings about technology applications based on
practical field experience across multiple sites,
including lessons learned. Some of these reports
contain information about the selection, design, and
implementation of a technology. Currently, 67 FRTR
remediation technology assessment reports are
available that cover 16 technology types and four
contaminant or site-type focus areas. These areas
include arsenic, dense non-aqueous phase liquids
(DNAPLs), underground storage tank (UST) sites or
fuel-contaminated sites, and persistent organic
pollutants (POPs).
HIGHLIGHT OF LONG-TERM
MONITORING AND OPTIMIZATION
CASE STUDY
Streamlined Remediation System Evaluation
(RSE-Lite), Cape Fear Wood Preserving
Site, Fayetteville, North Carolina
Soi , sediment, and groundwater were
contaminated with polycyc ic aromatic
hydrocarbons at the Cape Fear Wood Preserving
Site in Cumberland County, North Carolina, A
groundwater remedy consisting of pump and
treat, air sparging, nutrient-enhanced
degradation, monitored natural attenuation, and
dense nonaqueous phase liquid (DNAPL)
extraction was initiated in August 2001, A
streamlined remediation system evaluation (RSE-
Lite) was conducted at the site to optimize system
performance. An RSE-Lite differs from a standard
RSE in that a conference call with the project
stakeholders is conducted instead of a site visit
to identify opportunities for optimization. At the
time the RSE-Lite was conducted, soi and sediment
had been remediated, and only groundwater
contamination remained. Recommendations to
improve the effectiveness of the system included
further delineation of the groundwater plume, and
excluding water level measurements from active
recovery wells and infiltration galleries when
generating potentiometric surface maps. Cost
reduction recommendations included use of local
labor for operation and maintenance services
and groundwater monitoring, and reduction in
the frequency of sampling in the source area from
auarterly to annually.

NON-COMBUSTION TECHNOLOGIES FOR PERSISTENT ORGANIC POLLUTANTS
Persistent organic pollutants, or POPs, are toxic compounds that are chemically stable, do not easily
degrade in the environment, and tend to accumulate and biomagnify as they move up through the food
chain. Under the Stockholm Convention, various countries have committed to the reduction or elimination
of the production, use, and re ease of the 12 POPs of greatest global concern. Some of these POPs
include aldrin, heptachlor, mirex, polychlorinoted biphenyls, dioxins, and furans.
The new POPs technology assessment report provides a summary of information on the applicability of
existing and emerging non-combustion technologies to remediate POPs in stockpiles and soil. The
report provides short descriptions of these technologies and evaluates them based on the POPs and
media treated, pretreatment requirements, performance, and cost. Case studies are provided and
show various considerations associated with selecting a non-combustion technology. Some of the full-
sea e technologies discussed in the report include anaerobic bioremediation using blood mea ,
mechanochemical dehalogenation, and gas phase chemical reduction. Pilot-scale technologies
discussed include base-catalyzed decomposition and sonic technology.
