        The Technology  Assessment  Branch  (TAB)
        (within the Technology Innovation and Field
     Services Division of the Office of Superfund Reme-
     diation &Technology Innovation) servesfederal and
     state site project managers, consulting professionals,
     and the public by providing information to improve
     hazardous waste site remediation. The Branch en-
     courages the responsible use of new and innovative
     treatment technologies to achieve more cost effec-
     tive soil and groundwater cleanup. TAB assesses and
     communicates state-of-the art information as it con-
     tinually evolves. TAB staff members report on new
     developments in a clear and concise manner to meet
     the needs of site managers. The Branch accomplishes
     its objectives through benchmarking technology im-
     provements and status, collaborating and partnering
     with other  organizations, and providing  program
     support and direct assistance  to project managers.
     The Clu-In Website (http://www.duin.org) serves as
     a repository for TAB resources and products.


     BENCHMARKING
        TAB primarily focuses on new developments for
        treatment  and restoration technologies for
     soil and groundwater, including in  situ processes
     for bioremediation of chlorinated compounds;  in
     situ thermal, chemical oxidation and solvent extrac-
     tion for nonaqueous phase liquids (DNAPLs); com-
     binations  of remedies; nanotechnologies; vegetative
     caps and  phytoremediation; ecological restoration
     techniques that contribute to productive  reuse of
     contaminated sites; and renewable energy  alterna-
     tives for site cleanup.  TAB personnel also maintain
     expertise and report on the remediation of selected
     contaminant groups and media such as DNAPLs;
     contaminated sediments; manufactured gas plants;
     persistent  organic pollutants;  abandoned mine
lands; and selected emerging contaminants, such as
1,4 dioxane, mercury, and perchlorate. The Branch
updates and reports current status information on
the Technology and Contaminant Focus areas on
http://www.duin.org.

TAB leads a joint effort with other federal agencies to
compile cleanup case studies and reports and make
them available in a searchable format on  the web
(http://www.frtr.gov). Over 800 reports are  available
that provide broad assessments of new treatment tech-
nologies, document cost and performance at specific
sites, evaluate new monitoring and site characterization
technologies, and document  efforts to optimize and
improve the cost effectiveness of operating remedies.

A new DNAPL focus area (http://www.duin.org/DNAPL),
which was recently added, will improve remedial deci-
sions by consolidating and organizing extensive infor-
mation in a single location. This focus area addresses
the most frequently encountered DNAPLs (chlorinat-
ed ethanes, creosote, coal tars, and heavy oils) and has
over 1,000 references and over 400 separate pages.

                 EcoTools: Tools for Ecological Land Reuse
                              Ecological reuse returns polluted or
                              otherwise disturbed lands to a function-
                              ing and sustainable use by increasing or
                              improving habitat for plants and animals.
                              "Ecological land reuse" is a broad term
                              that encompasses a number of interre-
                              lated activities including the reconstruc-
                              tion of antecedent physical conditions,
                              chemical adjustment of the soil and
                              water, and biological manipulation which
                              includes the reintroduction of native flora
                              and fauna. EPA promotes land reuse
                programs that consider the inextricable links between all life
                forms and all media within an ecosystem rather than an isolated
                manipulation of individual elements. Reuse of contaminated
                sites, when based on ecological principles, can complement
                traditional remediation activities that ensure the protection of
                human health and the environment, in addition to creating habi-
                tat. Ecological land reuse can be a cost-effective way to create
                or incorporate habitats as natural remediation tools that are part
                of the cleanup process for contaminated sites.
                     EcoTools Homepage


          As part of an effort to foster ecological revital-
          ization  and reuse  of Superfund sites,  a  new
    web resource, EcoTools, was developed to focus on
    ecological revitalization of contaminated property
    (http://www.duin.org/ecotools). The site  provides in-
    formation on the principles of ecological reuse of con-
    taminated properties; resources for support including
    other OSRTI fact sheets and other agency reports on the
    subject; and links to information on soil amendments,
    native and invasive plant species, and ecosystem-based
    restoration. The web site provides a comprehensive list
    of region-by-region and state-by-state federal and local
    resources for ecological restoration projects.
The site also contains a recently published report, Eco-
logical  Revitalization: Turning  Contaminated Prop-
erties into  Community Assets (EPA-542-R-08-003),
which was developed by a cross-OSWER cleanup-
program team made up of ecological revitalization
experts from Superfund and other EPA offices that
regulate cleanup programs for  solid and hazardous
waste and petroleum. The document addresses plan-
ning-level issues and highlights considerations and
initiatives under different OSWER cleanup programs
and case studies that provide examples of completed
ecological  revitalization projects at cleanup  sites.
The case studies are particularly noteworthy because
they provide over 80 examples where revitalization
was accomplished for a variety  of remediation proj-
ects. A second report, The Use of Soil Amendments
for Remediation, Revitalization and Reuse (EPA 542-
R-07-013),  addresses the principles of applying soil
amendments for remediating and revegetating con-
taminated sites that have degraded soils. It focuses
on amendments that are generally residuals (such as
biosolids) from other processes, but have beneficial
properties when added to soil.


TAB  recently  published  Nanotechnology for Site
Remediation Fact Sheet (EPA 542-F-08-009), which
provides a  snapshot of nanotechnology and its
current uses in remediation. This document  pro-
vides information to help project managers select
and use new technologies, as well as help them un-
derstand the potential applications of this group of
technologies at their sites. The fact sheet includes
information on sites where nanoparticles have been

           Leadville, CO, before and after the use of soil amendments for remediation, revitalization, and reuse.

     Site profiles on selected technologies are main-
     tained on CLU-IN On-line Remediation Databases
     at http://www.cluin.org/databases. TAB maintains
     eight  technology  and  contaminant-specific da-
     tabases with updated and formatted information
     that can be searched through a universal search
     engine. Information is provided on pilot- and full-
     scale applications of innovative treatment and site
     characterization technologies.


     The Branch manages publication of Technology News
     and Trends, a bi-monthly newsletter highlighting re-
     cent developments for treatment and site character-
     ization. It is broadly distributed to the remediation
     community and written  by federal and state project
     managers to inform their peers about important new
     developments at sites.

     TAB sponsors a national annual conference on a
     subject related to innovative and treatment technol-
     ogies. Recent conferences have addressed methods
     to improve site monitoring and characterization and
     the application of nanotechnology.
COLLABORATION
and PARTNERSHIPS
    TAB products are developed in collaboration with
    a broad array of site cleanup  professionals and
groups who serve as state, federal, and industry part-
ners. The Branch supports the Federal Remediation
Technologies Roundtable,  which is a cooperative
effort among federal agencies with active remedia-
tion programs. Member agencies attend twice-yearly
meetings to share information and discuss collabora-
tive efforts to benefit from  each others experience.
FRTR members share information on topics such as
alternative energy sources.  The technical presenta-
tions at the meetings are broadcast to interested agen-
cy staff through a web conference, and are archived at
http://www.frtr.gov/meetings2.htm.

The Branch supports the State Coalition for Remedia-
tion of Drycleaners (http://www.drydeancoalition.org),
a partnership with states  that captures informa-
tion on the performance and lessons learned from
application  of innovative  technologies at chlori-
nated solvent drycleaner sites.  The  coalition is
made up of 13 states with established drycleaner
remediation programs. A 10 Year Accomplishment
Report—State Coalition for the Remediation  of
Drycleaners (EPA 542-R-08-004,  October 2008) is
a recent  progress report of the accomplishments

    from this collaborative effort. The Coalition doc-
    uments and shares technical information  about
    actual site cleanups. Profiles for almost 150  reme-
    diation projects  help site managers make  better
    informed decisions.

    TAB provides funding
    and management to help
    support  the  Technical
    Support Project, which
    is  an  EPA  headquar-
    ters/regional/laboratory
    partnership  to  address
    issues concerning char-
    acterization  and reme-
    diation. The project in-
    cludes   senior scientific
    and  engineering staff,
    who participate  in  the
    Ground  Water,  Federal
    Facilities and  Engineer-
    ing  Forums. TAB also  supports  the new  National
    Sediments Forum, made up of regional sediments
    project managers, and supporting headquarters and
    laboratory sediments experts.

    In addition,  TAB works with states by participating
    as federal liaisons to the Board of Advisors  of the In-
    terstate Technology & Regulatory Council (ITRC)
    and technical team members.  The ITRC is a state-
    led organization that develops information  resources
    and training on innovative cleanup technologies and
    approaches.

PROGRAM  and
TECHNICAL SUPPORT
T ATTiile  new information benefits all hazardous
 V V waste sites, the Branch's primary function is to
increase the cost effectiveness of Superfund remedies.
Staff members work on issues encompassing the entire
Superfund process, including remedy selection, con-
struction, post-construction, policy/guidance develop-
ment (e.g., risk-sharing), and program evaluation.

The status of Superfund technology use is reported
in the 12th Edition of Treatment Technologies for Site
Cleanup: Annual Status Report (ASR). The report
provides data  on technology  applications at more
than 1,900 soil and groundwater projects and shows
continued progress in treating waste in place and ef-
forts to implement innovative technologies.  TAB is
currently compiling data on Superfund remedies se-
lected in fiscal years 2005-8. Results are expected to
be published in the fall of 2009.

Direct technical consultation and support is provid-
ed through Technical Support Centers  (Sediment,
Ecological Revitalization, and funding for ORD Lab-
oratories) and directly by individual TAB staff.
