Description:
The U.S. Environmental Protection Agency's Office of Research and Development (ORD) is examining processes for remedial action at Superfund sites, and corrective action at operating disposal sites. ecent legislation emphasizes destruction and detoxification of contaminants, rather than containment or storage of contaminated soils. hemical treatment appears promising because it can destroy or greatly change many contaminants. Oxidation, reduction, neutralization, hydrolysis, dehalogenation, and UV/photolysis are chemical processes currently used for aboveground treatment. Temperature and physical and chemical characteristics of soil are some operating parameters that control the effectiveness of these processes. xcalibur catalytic ozone technology, Exxon & Rio Linda cyanide destruction, and Trinity ultrasonic detoxification are innovative technologies that have been, or are currently being considered for pilot-scale demonstrations. This paper has been reviewed in accordance with the U.S. Environmental Protection Agency's peer and administrative review policies and approved for presentation and publication.
