Soil Washing |

Soil washing is an exsitu 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 grained soils (silts and ...
