Upcoming Live Internet Seminars
ITRC Planning and Promoting of Ecological Land Reuse of
Remediated Sites - May 15. This training is based on the ITRC
Technical and Regulatory Guideline: Planning and Promoting
Ecological Land Reuse of Remediated Sites (ECO-2, 2006). The
document presents a process to promote ecological land reuse
activities considering natural or green technologies instead of
more traditional remedies. The guidance demonstrates that
natural or ecological end-uses are valuable alternatives to
conventional property development or redevelopment. Ecological
benefits and a process for calculating their value are included
in the guidance and reviewed in this training. For more
information and to register, see http://www.itrcweb.org or

Management and Interpretation of Data Under a Triad Approach -
May 22. This session will cover the Brownfields and Land
Revitalization Technology Support Center (BTSC) bulletin on
implementing a data management program for a Triad project. It
will include a brief introduction to the Triad approach, answers
to frequently asked questions about data management on Triad
projects, three examples of data management with state agencies
as the primary regulatory body, and sources of additional
information for project teams and stakeholders who develop or
provide input on data management. For more information and to
register, see http://clu-in.org/studio .
Bioavailability - Metals - May 28. The Superfund Basic Research
Program (SBRP), in collaboration with the Environmental
Protection Agency (EPA) Technology Innovation Program, presents
'Bioavailability - Metals.' Dr. Dominic Di Toro, Professor of
Civil and Environmental Engineering, University of Delaware,
will review available models - the Free Ion Activity Model, the
Biotic Ligand Model and Equilibrium Partitioning - and
supporting data for water column, sediments and soils and will
present example applications to human health in his presentation
'Environmental Control of Metal Bioavailability.' Dr. Nicholas
Basta, Professor, Soil and Environmental Chemistry, Ohio State
University, will present data gaps, uncertainties and research
needed to apply in vitro gastrointestinal (IVG) methods to
contaminated sites in his presentation 'Assessing Contaminant
Human (Bio)availability in Soil with In Vitro Gastrointestinal:
Uncertainties, Data Gaps, and Research Needs.' For more
information and to register, see http://clu-in.org/studio .
ConSoil 2008 Special Sessions on Green Remediation (June 5) and
Brownfields, Bioenergy and Biofeedstocks (June 6). EPA is
collaborating with the European Groundwater and Contaminated
Land Information Portal to bring to you live, via Webcast, two
90-minute special sessions on sustainability and contaminated
site cleanup. These sessions are being held at the 2008 ConSoil
Conference in Milan, Italy. The sessions link two important
emerging themes for contaminated land management, both connected
with improving its sustainability and reducing its cost. The
first theme is the integration of land management of large areas
with re-use for non-food crops, ecosystem recovery and revenue
generation. The second is what is termed 'green remediation,'
which maximizes the net environmental benefit of contaminated
land remediation techniques. For more information and to
register, see http://clu-in.org/studio .
New Documents and Web Resources
Green Remediation: Incorporating Sustainable Environmental
Practices into Remediation of Contaminated Sites (EPA
542-R-08-002). Green remediation is the practice of considering
all environmental effects of remedy implementation and
incorporating options to maximize the net environmental benefit
of cleanup actions. This primer outlines the principles of green
remediation and describes opportunities to reduce the footprint
of cleanup activities throughout the life of a project. Best
management practices (BMPs) outlined in this document help
decision-makers, communities, and other stakeholders (such as
project managers, field staff, and engineering contractors)
identify new strategies in terms of sustainability. These
strategies complement rather than replace the process used to
select primary remedies that best meet site-specific cleanup
goals. The primer identifies the range of alternatives available
to improve sustainability of cleanup activities and to help
decision-makers balance the alternatives within existing
regulatory frameworks. To date, EPA's sustainability initiatives
have addressed a broader scope or focused on individual elements
of green remediation such as clean energy (April 2008, 54
pages). View or download at http://clu-in.org/techpubs.htm .
Engineering Forum Issue Paper: Online Hazardous Waste Cleanup
Technical Resources (EPA 542-F-08-003). This issue paper is
intended to give the reader examples of some online technical
resources that can assist with hazardous waste cleanups in the
Superfund, Resource Conservation and Recovery Act (RCRA), and
Brownfields programs. Given the dynamics of online resources,
this paper provides only a snapshot of the resources available
at the time of publication (April 2008, 12 pages). View or
download at http://clu-in.org/techpubs.htm .
Technology News and Trends (EPA 542-N-08-002). This issue
contains articles on an adaptive treatment strategy to address
extensive DNAPL contamination, sodium persulfate and hydrogen
peroxide injections to achieve ground-water cleanup, and an
integrated technology approach to remediate a site contaminated
by 56 chemicals (April 2008, 6 pages). View or download at
http://clu-in.org/techpubs.htm .
Remediation Technologies for Perchlorate Contamination in Water
and Soil (PERC-2). This report was produced by the Interstate
Technology and Regulatory Council (ITRC). The purpose of this
document is to review technologies applicable to the remediation
of perchlorate in water and soil. In addition, the social,
political, and regulatory barriers to the deployment of these
technologies are examined. The goal of the document is to
provide industry, responsible parties, and state and federal
environmental regulators with reliable guidance to help
streamline the review and approval process for selecting and
implementing perchlorate treatment technologies (March 2008, 109
pages). View or download at
