Description:
Treating large volumes of contaminated soil at Superfund sites is costly. he Superfund Amendments and Reauthorization Act (SARA), and the Resource Conservation and Recovery Act (RCRA) have provisions, which regulate the removal treatment, and ultimate disposal of contaminated soils and wastes from Superfund sites. These factors have led the U.S. EPA's Superfund Program to consider in situ chemical treatment as an alternative technology for treatment of contaminated soil. In this technology, the soil does not require to be excavated and moved elsewhere. xidation, reduction, neutralization, hydrolysis, dehalogenation, and UV/photolysis are chemical processes currently used for above-ground treatment. emperature, physical and chemical characteristics of soil, are some operating parameters that control the effectiveness of these processes. mprovements in mixing treatment materials in soil, and methods for recovering unreacted material reaction products, are needed to allow wider application of these treatments in situ. xcalibur catalytic ozone technology, Exxon & Rio Linda cyanide destruction, and Trinity ultrasonic detoxification are innovative technologies that are being, or are currently been considered for pilot scales 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.
