AbstractA literature review and screening study suggest the feasibility of using low‐cost organic materials within a permeable reactive barrier (PRB) to treat ura‐nium‐contaminated water. Natural peat deposits remove and sequester ura‐nium from ground water under certain geochemical conditions while several species of bacteria, including Desulfovibrio desulfuricans precipitate soluble uranium from solution. Cation exchange capacities were measured for saw‐dust and peat, materials to be used in construction of a small‐scale PRB. Re‐sults of a literature review and the cation exchange capacity measurements suggest that organic materials, such as peat, can be used to remove soluble uranium from contaminated water. © 2006 Wiley Periodicals, Inc.

AbstractThe 2004 National Defense Authorization Act (NDAA) granted relief to the Department of Defense (DOD) on compliance with certain provisions of the Endangered Species Act (ESA). Specifically, the Secretary of the Interior was mandated to exempt DOD from critical habitat designation on military installations provided that the installation had an Integrated Natural Resources Management Plan (INRMP), as required by the Sikes Act, and the resources to effectively implement the plan. DOD viewed this legislative relief as an important step in addressing one element of general encroachment concerns on military lands. This article reviews the background of the critical habitat issue on military lands and the steps that led to the provisions included in the 2004 NDAA. To determine the status and degree of implementation of the ESA provisions of the 2004 NDAA in the U.S. Air Force (USAF), the principal author conducted a survey of USAF range natural resources managers. The results of that survey indicate that the USAF is meeting the requirements of the 2004 NDAA by having valid INRMPs for its installations and by providing adequate funding for their implementation. However, the survey results suggested several areas where improvement was needed, particularly in educating natural resources managers about documenting the impacts of critical species on training ranges, partnering with outside groups to leverage manpower and financial resources, and improving public education and awareness of USAF training range environmental programs. © 2004 Wiley Periodicals, Inc.

The following article is taken as an excerpt from the proceedings of the annual Acquisition Research Program. This annual event showcases the research projects funded through the Acquisition Research Program at the Graduate School of Business and Public Policy at the Naval Postgraduate School. Featuring keynote speakers, plenary panels, multiple panel sessions, a student research poster show and social events, the Annual Acquisition Research Symposium offers a candid environment where high-ranking Department of Defense (DoD) officials, industry officials, accomplished faculty and military students are encouraged to collaborate on finding applicable solutions to the challenges facing acquisition policies and processes within the DoD today. By jointly and publicly questioning the norms of industry and academia, the resulting research benefits from myriad perspectives and collaborations which can identify better solutions and practices in acquisition, contract, financial, logistics and program management.

The use of ADR to resolve disputes typically provides a quick and inexpensive resolution when compared to litigation. The Air Force has a very strong ADR program to resolve acquisition and workplace disputes; however, the varied conditions and situations of environmental issues have prevented the Air Force from achieving similar success in this area. This research analyzes the experiences of twenty-six Environmental Conflict Resolution practitioners who have resolved environmental disputes using ADR techniques. Content analysis and pattern matching were used to provide insight into the current use of ADR techniques in military environmental disputes. The insight gained from this research provides the Air Force with information to better understand the current practices in environmental ADR and also provides areas for further research. ; Third Annual Acquisition Research Symposium ; Approved for public release; distribution is unlimited.
