Situ Bioremediation of inorganics, and DNAPL source
treatment. The spring 2008 meeting focused on issues
related to remediation of contaminated sediment.
A major activity of the Roundtable throughout the
year is collection and distribution of information
from federal and state agencies on the use of new
technologies at their sites. Each year, the Roundtable
compiles reports and makes them available at its Web
site www.frtr.gov. This year, the Web site was revised to
make it more functional and responsive to the needs of
users. This fact sheet highlights some of the revisions
and describes the status of new cost and performance
information and federal and state reports that were
added for the spring 2008 update.
Recent changes to the Web site will make it more
user-friendly and easier to navigate. Figure 1
provides a snapshot of the new design and shows the
variety of information available on the homepage.
The navigation buttons are rearranged so that the
frequently used sections are listed first. In addition, a
new "Archives" section has been created to preserve
information in reports and publications that are older
than five years. The "What's New" section provides
notices about meetings, conferences, publications,
etc. of interest to FRTR members and will be updated
monthly to showcase noteworthy reports and events
suggested by member agencies. The cost and
Performance Case Studies section has been expanded
to provide access to all FRTR case study databases.
REMEDIATION TECHNOLOGY COST
AND PERFORMANCE CASE STUDIES
More than 400 Remediation (treatment or containment)
Technology Cost and Performance Case Studies are
available on the FRTR Web site. Eight new cost and
performance case studies for remediation technologies
have been added. These new case studies involve
the use of In situ treatment technologies for treating
contaminated soil and ground water. Three reports
developed by the Air Force Center for Engineering
and the Environment (AFCEE) involve enhanced In situ

New DNAPL Web Site (www.cluin.ora/DNAPL)
EPA's Technology Innovation Program has developed
one location comprehensive information about the
cleanup of dense nonaqueous-phase liquids (DNAPLs)
at hazardous waste sites. The DNAPL Web site was
developed as the result of a recommendation by the EPA
Ground WaterTask Force (www.gwtf.clu-in.org). The site
covers the full range of potential DNAPL remediation
technologies: bioremediation, containment, direct and
multiphase recovery, in situ flushing, in situ oxidation, in
situ reduction, permeable reactive barriers, soil vapor
extraction and air sparging, solidification/stabilization,
source area excavation, in situ and ex situ thermal
treatment, and in situ treatment trains.
This initial phase of the DNAPL Web site addresses the
most common DNAPL contaminants: chlorinated ethenes
(for example, tetrachloroethene and trichloroethene) and
National Research Council's Report
on Sediments Dredging at Superfund
Megasites: Assessing the Effectiveness
EPA sponsored a recent study by the National Research
contaminated sediments from harbors, lakes, and rivers.
The report prepared by NRC considers the technical
limitations that affect successful implementation of
dredging, the problems encountered by incomplete
removal of sediments and resuspension, the value
of centralizing data related to dredging, and the
importance of increased monitoring at sites where
dredging was used.
The report is available for purchase through the
National Academies Press (www.nap.edu) and is also
available to download for free on the EPA Web site
(www.epa.gov/superfund/health/conmedia/sediment/

anaerobic bioremediation of chlorinated solvents at
Air Force bases in Florida, Ohio, and Missouri. Two
reports prepared by DoD's Environmental Security
Technology Certification Program (ESTCP) provide
cost and performance data for treating contaminated
soil and ground water using enhanced reductive
dechlorination from substrate addition and using
palladium catalysts and horizontal flow treatment
wells. Two case studies developed by EPA include soil
vapor extraction, and In situ chemical oxidation to treat
former dry cleaner sites. Another EPA study documents
use of electrical resistive heating and biosparging to
remediate contamination at a pharmaceutical site.
SITE CHARACTERIZATION AND
MONITORING REPORTS
This focus area includes reports on field-based site
characterization and monitoring technologies and
over 1 75 reports are currently available. Four new
reports have been added, one each from Interstate
Technology & Regulatory Council (ITRC) and DOE,
and two from ESTCP. ITRC consists of a diverse
mix of environmental experts and stakeholders from
the private sector and public sectors including EPA,
multiple federal partners, state agencies, industry
participants, and other stakeholders. The ITRC report
provides a general overview of the implementation
of the Triad process. This report is a "How-To" guide
to implement Triad and provides in-depth discussions
on how to address organizational, cost, and technical
challenges. The report provides supporting information
in the appendices, such as sample implementation
documents. This report is a companion document to the
first Sampling, Characterization, and Monitoring Team
document, Technical and Regulatory Guidance forthe
Triad Approach: A New Paradigm for Environmental
Project Management (ITRC 2003).
The report from DOE describes a field validation study
that was conducted to evaluate the performance of the
Accu Core samplerto store volatile organic compounds
(VOC) in soil samples during transportation to the
laboratory for analysis. The report also compares the
performance of the Accu Core with current sampling
and storage techniques. The two reports from ESTCP
provide information related to Passive Flux Meters
(PFMs) and field demonstration and validation of this
new device for measuring contaminant loadings from
source zones.
HIGHLIGHT OF NEW
REMEDIATION CASE STUDY
In Situ Catalytic Groundwater Treatment
Using Palladium Catalyst and Horizontal
Flow Treatment Wells (HFTW)
This ESTCP/Air Force report provides information on a
Edwards Air Force Base, Site 1 9, in California to treat
trichloroethene (TCE) contaminated groundwater
using palladium (Pd) catalyst and horizontal flow
treatment wells (HFTW). The purpose of the
demonstration was to (1) demonstrate the feasibility
of chlorinated ethenes in groundwater using Pd
catalyst, (2) optimize treatment efficiency, and (3)
develop cost and performance data for full scale
TCE was 5 micrograms per liter (/Jg/L). The treatment
system included a column reactor, a hydrogen feed
system, and an automatic bleaching system to allow
for catalyst regeneration. The column reactor was
designed in conjunction with existing HFTWs at
the site. Bleaching the Pd catalyst was required
to prevent the growth of sulfidogenic bacteria
and remove inhibitory materials from the catalyst
surface. The treatment system was able to reduce
the concentration of TCE that ranged from 800 to
1,200/Jg/L in the influent to below the cleanup goal
after one pass through the Pd column reactor with a
contact time of approximately one minute. Average
removal percentage was 99.6 percent outside
bleaching periods and 95.5 percent if concentrations
during the bleaching periods were included.
The total capital cost for this demonstration was
$574,000 and annual operation and maintenance
cost was $48,350.

HIGHLIGHT OF NEW CHARACTERIZATION REPORT
Field Demonstration and Validation of a New Device
for Measuring Water and Solute Fluxes at CFB Borden
This ESTCP report provides information on a
demonstration and validation of a new monitoring
technology known as the passive flux meter (PFM).
This device allows in situ measurement of cumulative
ground water and contaminant fluxes in contaminated
aquifers and could provide a new means for assessing
the strength of source areas. The PFM measures
water flux and can be used to calculate flux-averaged
contaminant concentrations. The document outlines
the results of three field tests at the CFB Borden
demonstration site in Toronto, Ontario. Two of the tests
used perchloroethylene (PCE) and trichloroethylene
(TCE) as the ground water contaminants, while MTBE
was the contaminant of concern for the third test. The
study concludes that PFM is a cost effective system to
flow, and produces the same information as that derived
from the integration of continuous monitoring data. PFM
was shown to be less sensitive to short-term fluctuations
in flow and concentration, and took less time, per well,
LONG-TERM MONITORING AND
OPTIMIZATION CASE STUDY REPORTS
This focus area includes reports describing long-
term management and optimization efforts covering
techniques such as ground water monitoring program
evaluation, plume capture evaluation, and hydraulic
optimization. More than 125 reports are currently
available under this focus area. New documents
include seven reports from DOE and ten from EPA.
Three of the DOE reports discuss optimization of
pump and treat remediation systems; one of these
also includes soil vapor extraction (SVE). All of these
offer recommendations for optimizing the efficiency
of systems for different operable units and sites. The
other four reports cover a range of technologies; one
study evaluates the use of chemical and biological
amendments to improve the performance of the In situ
redox manipulation (ISRM) barrier at the Hanford Site in
Washington. The amendments evaluated to mend the
barrier and restore its effectiveness include dithionite,
calcium polysulfide, micron-scale iron, nanoscale iron,
dissolved iron, and biostimulants. Othertechnologies
that were evaluated for optimization include electrical
resistance and steam heating.
Five of the ten reports prepared by EPA relate to
optimization of pump and treat remediation systems.
Three reports are Remediation System Evaluations
(RSEs) that address free product recovery, In situ air
stripping, and chemical precipitation for dissolved
metals in ground water. Two reports evaluate long-term
ground water monitoring optimization at sites that use
pump and treat system and In situ redox manipulation
treatment technology.
REMEDIATION TECHNOLOGY
ASSESSMENT REPORTS
The reports in this section provide broad assessments
of technologies based on results from field experience
gained from multiple sites. Five reports were added
to this focus area, bringing the total to more than
eighty. Two new reports (one from ITRC and one
from AFCEE) provide information about In situ
bioremediation for treating DNAPL and chlorinated
solvents. The third report examines the use of soil
amendments for remediation, revitalization and reuse.
This report prepared by EPA provides an overview of
issues related to soil amendments; types of problems
addressed by soil amendments; types of sites where soil
amendments can be used; types of soil amendments;
logistics, permitting and regulations; and sampling
and monitoring of amended sites. The fourth report
provides a systematic approach for evaluating capture
zones at pump and treat systems. The fifth report by
ITRC provides remediation technologies for treating
perchlorate in soil and water.

Remedial System Evaluation: Northwest Pipe
and Casing Site, Clackamas, Oregon
This Remedial System Evaluation (RSE) report by
EPA provides recommendations to help identify
opportunities for improvement by addressing
effectiveness, cost reduction, technical improvements,
and site close out. An RSE was conducted at the
Northwest Pipe and Casing site located in Clackamas,
Oregon. Recommendations for improving system
effectiveness include improving delineation of the
plume, finalizing institutional controls, and evaluating
potential for vapor intrusion. Recommendations
for cost reduction include eliminating the existing
ground water circulation wells, which would result in
a savings of approximately $166,300 per year for
operation and maintenance of the current system.
Recommendations fortechnical improvement include
revising sequencing for collecting site-wide water
level data. Finally, recommendations forsite closeout
include clarifying and documenting goals for active
remediation, and implementing in situ bioremediation
in conjunction with natural remediation to reduce
the highest concentrations of volatile organic
compounds.
Remediation Technologies for Perchlorate
Contamination in Water and Soil
This Interstate Technology & Regulatory Council
document provides an overview of treatment
technologies used to remediate perchlorate in
contaminated water and soil. The report provides
site evaluation, remedy selection, and regulatory
considerations and treatment technologies. The
report also provides three case studies for the
using a variety of treatment technologies. Treatment
(ion exchange, granular activated carbon, reverse
osmosis, nanofiltration/ultrafiltration, electrodialysis,
and capacitive deionization); three in situ biological
treatment approaches (source zone treatment, plume
containment using a biologically reactive barrier,
and plume-wide restoration); three ex situ biological
treatment systems (fluidized bed reactor, packed-
bed reactor, and continuously stirred tank reactor);
and phytoremediation and phytodegradation.
Information on the availability, performance, and
cost of each technology is also provided.
