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

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

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

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

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
