soil washing materials

Soil Washing - an overview | ScienceDirect Topics
Soil-washing (solvent extraction) Soil-washing is a solvent-extraction process. It uses the difference in the solubility of petroleum and the soil in water as the driving force. First, contaminated soils are usually excavated (although in situ soil flushing systems do exist) and the soil screened to remove large rocks and materials.

Soil Washing | Geoengineer.org
Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine
