Soil Washing Geoengineer

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 grained soils (silts and

PROCESS bioremediation

Ex situ. Ex situ bioremediation involves the physical extraction of the contaminated media to another location for treatment. If the contaminants are just in the soil, the contaminated soil is excavated and transported for treatment. If the contamination has reached the groundwater, it must be pumped and any contaminated soil must also be removed.
