SERDP Solicitation Open The DoD Strategic Environmental Research and Development Program (SERDP), will be funding environmental research and development. The objective of this effort it to identify, develop, and transition environmental technologies that relate directly to defense mission accomplishment. SERDP intends to fund multiple projects within each core thrust area. Projects will be selected through a competitive selection process. Because both government and private sector parties may compete for SERDP funds, there are two announcements for each solicitation. Proposals in the following areas are requested: Environmental Restoration — innovative technologies for the detection, characterization, containment, and remediation of a wide range of contaminants in soil, sediments, and water. Munitions Management — advanced geophysical sensor and signal processing technologies for the detection, discrimination, and remediation of Unexploded Ordnance (UXO) and technologies for range clearance and reduced generation of UXO. Weapons Systems and Platforms — advanced alternative environmentally benign technologies and materials that reduce, control, or eliminate the waste and emissions associated with the manufacturing, maintenance, and use of DoD weapons systems and platforms. TechDirect: December 1, 2005 1 of 7 clu-in.ora/newsletters ------- Pre-proposals from the non-federal sector are due by Thursday, January 05, 2006. Proposals from the federal sector are due by Thursday, March 16, 2006. Detailed instructions for federal and private sector proposers are available on http://www.serdp.ora/fundina/index.cfm . Internet Seminars ITRC Site Investigation and Remediation for Munitions Response Projects - December 6. This training provides an introduction and overview of the processes, tools, and techniques used in investigation and remediation. These concepts are illustrated using an example munitions response site. Major steps in each process are identified and key regulatory considerations discussed. This training also identifies additional sources for more detailed information on key aspects of investigation and remediation. State regulators and others who need to understand the general processes involved in these critical aspects of the munitions response process will benefit from this training. For more information and to register, see http://www.itrcweb.ora Of http://clu-in.org/studio . ITRC Perchlorate: Overview of Issues, Status, and Remedial Options - December 8. There are an estimated 2,000 munitions-contaminated sites located in all 50 states and territories that may affect more than 10 million acres. State and tribal regulatory officials and community stakeholders are routinely required to evaluate DOD cleanup strategies with little, if any, environmentally oriented munitions response experience or guidance. State regulators are increasingly being charged with oversight responsibility for munitions response cleanup projects on other than operational ranges, such as formerly used defense sites (FUDS) and base realignment and closure (BRAC) sites. In addition, DOD project managers and industry will benefit from a greater understanding of state regulator expectations.

The Basics: Understanding the Behavior of Light Non-Aqueous Phase Liquids (LNAPLs) in the Subsurface - December 12. This seminar provides a basic description of the behavior of LNAPLs (specifically, petroleum hydrocarbon liquids) in the subsurface. It is offered by the Remediation Technologies Development Forum (RTDF)/Non-Aqueous Phase Liquid (NAPL) Cleanup Alliance, a public-private partnership supported by the U.S. Environmental Protection Agency. Presenters begin by defining important terms to provide a foundation for discussing LNAPL behavior. They will explain how the general understanding of the behavior of LNAPL in TechDirect: December 1, 2005 2 of 7 clu-in.ora/newsletters ------- the subsurface has changed over the years. The presenters will discuss the effect of aquifer properties such as porosity, saturation, and capillary pressure and the effect of fluid properties - like viscosity, density, and interfacial and surface tension - impact LNAPL distribution and recovery. Presenters will introduce methods of predicting and evaluating LNAPL recovery, briefly discuss some assessment methods and techniques, and look at core photos taken from actual LNAPL plumes. Finally, five case studies will illustrate how the basic concepts conveyed in this training have been applied in the real world. For more information and to register, hHD://d»-in.0m/st»di0. ITRC Geophysical Prove-Outs for Munitions Response Projects - December 13. Geophysical systems are used to detect surface and subsurface anomalies, (i.e. unexploded ordnance (UXO) and/or discarded military munitions) during geophysical surveys of munitions response sites. These systems are tested, evaluated and demonstrated by a site-specific geophysical prove-out (GPO). Information collected during the implementation of the prove-out is analyzed and used to select or confirm the selection of a geophysical system that can meet the performance requirements established for the geophysical survey. htto://www.itrcweb.ora Of http://clu-in.ora/studio .

This EPA guidance document focuses on direct push technology (DPT) groundwater sampling issues. It addresses two groundwater sampling methods (i.e., point-in-time and grab sampling). The cost saving potential of DPT groundwater sampling technologies coupled with a rapid method of analysis, provides new defensible opportunities for making site decisions and an efficient project management tool for on-site activities. This guidance summarizes DPT groundwater sampling methods; the relevant data quality objectives; recommended TechDirect: December 1, 2005 3 of 7 clu-in.ora/newsletters ------- methods for collecting representative groundwater samples; and recommended methods for minimizing the potential for cross-contamination. It is intended for environmental professionals who have basic scientific understanding of groundwater sampling and DPT equipment and should be used with existing resources and initiatives that support the adoption of a dynamic field activity approach (August 2005, 78 pages).

This report was published by the U.S. EPA Office of Superfund Remediation and Technology Innovation. Triad practitioners are developing a growing collection of information about the technical implementation of the Triad. Only limited information is available regarding the procurement of sampling and analytical services under a Triad framework. Specifically, the dynamic nature of this approach requires that Triad-specific procurement issues be addressed, namely providing the flexibility and adaptability during project implementation that are crucial to the success of the Triad and to allow for the thorough, up-front planning required by the approach. This document highlights methods and strategies that have been successfully used to procure services under a Triad framework. It includes examples and lessons learned from actual Triad projects implemented in the federal, state, local, and private sector arenas (June 2005, 63 pages).

This document, published by the Interstate Technology and Regulatory Council (ITRC), TechDirect: December 1, 2005 4 of 7 clu-in.ora/newsletters ------- presents a technological overview of in situ bioremediation (ISB) and some of the issues to consider when selecting and designing an ISB system for remediation of chlorinated ethene dense nonaqueous phase liquids (DNAPLs) source zones. ISB is the use of bioaugmentation and biostimulation to create anaerobic conditions in groundwater and promote contaminant biodegradation for the purposes of minimizing contaminant migration and/or accelerating contaminant mass removal. Bioaugmentation is the addition of beneficial microorganisms into groundwater to increase the rate and extent of anaerobic reductive dechlorination to ethene. Biostimulation is the addition of an organic substrate into groundwater to stimulate anaerobic reductive dechlorination. ISB remediation may be implemented separately or in conjunction with other treatments designed to remediate DNAPLs in groundwater. ISB treatments generally involve modifications to the subsurface environment to accelerate biodegradation (October 2005, 89 pages).
