  • Process for removing hazardous, toxic, and radioactive wastes from soils, sediments, and debris
    Patent number: 5434332
    Abstract: A process for reducing the levels of contaminants in soils, sediments and debris comprised of an immersion of the soils, sediments and debris in a solvent, and the full drainage of the solvent from the soils, sediments and debris. The contaminants can be organic chemicals, metals, or radioactive materials. The process eliminates the effect of channeling, and allows contaminant levels to be brought to very low levels throughout the soils, sediments, and debris being processed.
