Cleaning excavated soil using extraction agents: A state-of-the-art review. Final report, June 1985-January 1989
This report presents a state-of-the-art review of soil-washing technologies and their applicability to Superfund sites in the United States. The review includes Superfund site soil and contamination characteristics, as well as soil cleaning technologies, their principles of operation, and process parameters. The technical feasibility of using soil-washing technologies at Superfund sites in the United States is assessed. Contaminants are classified as volatile, hydrophilic, or hydrophobic organics; PCBs; heavy metals; or radioactive material. Soils are classified as either sand, silt, clay, or waste fill. Three generic types of extractive treatments are identified for cleaning excavated soils: water washing augmented with a basic or surfactant agent to remove organics, and water washing with an acidic or chelating agent to remove organics and heavy metals; organics-solvent washing to remove hydrophobic organics and PCBs; and air or steam stripping to remove volatile organics.
