Upcoming Solicitation

People, Prosperity and the Planet - Searching for Green Technologies. Do you have an idea for a cutting-edge technology that could protect the environment while growing the economy? The U.S. Environmental Protection Agency (EPA) is offering college professors and their students an opportunity to turn ideas into reality through its P3 (People, Prosperity and the Planet) grants competition. EPA’s P3 is a student design competition for sustainability. Previous P3 winners have already taken their innovations to the next level – including starting successful businesses, winning additional awards, and providing environmental solutions to developing countries. The P3 request for ideas will be open from August 15 to December 21, 2006. Interdisciplinary student teams will compete for $10,000 grants to research and develop their design projects during the 2007-2008 academic year. EPA expects to award approximately 100 new grants from the eligible applications in the summer of 2007. For more information, see http://www.epa.gov/P3 .

Upcoming Internet Seminars

ITRC Overview of Direct-push Well Technology for Long-term Groundwater Monitoring – August 3. Direct-push wells have been used for temporary groundwater monitoring purposes for many years but are generally prohibited for use as long-term groundwater monitoring wells. Recent research indicates that direct-push wells are as well suited for long-term environmental groundwater monitoring purposes as conventionally constructed wells. This training introduces ITRC's The Use of Direct-push Well Technology for Long-term Environmental Monitoring in Groundwater Investigations (SCM-2, 2006), provides a background in the principles of direct-push wells, and presents the state of the art regarding recent research. For more information and to register, see http://clu-in.org/studio .

ITRC Radiation Risk Assessment: Updates and Tools – August 10. The ITRC has developed a document, Determining Cleanup Goals at Radioactively Contaminated Sites: Case Studies (RAD-2, 2002), that examines the factors influencing the variations in cleanup level development at various radioactively contaminated sites. This document underscores the need for radiation risk assessment training to enhance consistency in risk assessment application. The document also acknowledges the differences between the 'dose approach' used at some sites and EPA's 'risk-based approach'. Since most radioactively contaminated DOE and DOD sites are developing cleanup goals under CERCLA authority, there is a need for a training course that clarifies the variations between these approaches and elaborates on the methodology used to develop risk-based remediation goals. To meet this need, this training course has been collaboratively developed by the ITRC Radionuclides Team and EPA's Superfund Office. The focus of this training is EPA's new radiation risk assessment tools, which can facilitate better decision making for accelerated cleanups. For more information and to register, see http://clu-in.org/studio .

Uses of Spatial Analysis and Decision Assistance (SADA) – August 15. Spatial Analysis and Decision Assistance (SADA) is free software that incorporates tools from environmental assessment fields into an effective problem solving environment. These tools include integrated modules for visualization, geospatial analysis, statistical analysis, human health risk assessment, ecological risk assessment, cost/benefit analysis, sampling design, and decision analysis. This seminar will highlight the tools used, but is not a tutorial for the software. For more information and to register, see http://clu-in.org/studio .

New Documents and Web Resources

Technology Reference Guide for Radiologically Contaminated Surfaces (EPA-402-R-06-003). The U.S. EPA Office of Radiation and Indoor Air (ORIA) developed this Technology Reference Guide for Radiologically Contaminated Surfaces to help identify surface decontamination technologies that can effectively remove radiological contaminants from building, structure, and equipment surfaces. These technologies may also be useful in the removal of non-radiological contaminants, such as hazardous metals, from surfaces. This Guide is designed to provide easy access to critical information on technologies that are commercially available (March 2006, 150 pages). View or download at http://www.epa.gov/radiation/docs/cleanup/402-r-06-003.pdf .

Assessing the Human Health Risks of Trichloroethylene: Key Scientific Issues (ISBN: 0309102839). This report was produced by the National Research Council. The NRC committee was asked to examine issues critical to developing an objective, realistic, scientifically based health risk assessment for trichloroethylene. It was asked to focus on hazard characterization and mode of action for trichloroethylene toxicity; possible approaches to synthesize epidemiologic data for characterization of hazard; human susceptibility in different subpopulations or life stages; evidence for effects from exposure to trichloroethylene alone compared with that for effects from mixtures of chemicals that include trichloroethylene; physiologically based pharmacokinetic (PBPK) modeling; dose-response assessment; and issues related to quantitative assessment of cancer and non-cancer risks. The report provides guidance in three major categories: hazard characterization, PBPK modeling, and dose-response assessment (July 2006, 472 pages). The complete report can be viewed and ordered online at http://www.nap.edu/catalog/11707.html#toc. The 28-page executive summary is also available for free download, see http://newton.nap.edu/execsumm_pdf/11707.

Survey of Munitions Response Technologies. The Strategic Environmental Research and Development Program (SERDP), Environmental Security Technology Certification Program (ESTCP), and the Interstate Technology Regulatory Council (ITRC) jointly developed this Munitions Response Technology document. This document provides an overview of the current status of technologies used for munitions response (MR) actions and, where possible, evaluates and quantifies their performance capabilities. It provides project managers and regulators an understanding of the performance capabilities of available technologies under real-world site conditions. Detailed observations and critical considerations in the application of munitions technologies are discussed, with particular emphasis on detection technologies (June 2006, 216 pages).
