The minmum additive waste stabilization (MAWS) demonstration program at the Fernald site
- Catholic Univ. of America, Washington, DC (United States)
The Minimum Additive Waste Stabilization (MAWS) Program involves the development and demonstration of an integrated-system (vitrification, soil washing, and water treatment) approach to the treatment of multiple waste streams at the Fernald site, which began in mid-1993. This paper discusses the major concepts underlying the MAWS approach, the main objectives of the program, and the progress that has been made to date. A soil washing process has been developed that achieves substantial volume reductions while producing a contaminant-enriched fraction suitable for blending with other waste streams to produce a vitrifiable feed. Glass-based waste forms have been developed for Fernald mixed waste blends that show excellent leach resistance, are processable using improved joule-heated vitrification technology, and achieve very high waste loadings. The large volume reductions obtained with this approach translate into substantial reductions in life-cycle remediation costs. These benefits should be widely applicable to other site.
