    A two-phase soil washing biosorption process was developed for the remediation of p,p′-DDT-contaminated soil. The process involved desorption of contaminants from soil using dilute primary alcohols (40% 1-propanol) followed by contaminant removal from cosolvent solutions using fungal biosorption. Bench scale remediation studies were preformed to simulate ex situ (recycling .

    Soil flushing is sometimes confused with soil washing because both use aqueous solutions to mobilize contaminants, but flushing is conducted in situ, whereas soil washing is an ex situ process. Results from studies of the performance of chemical mixtures for removing contaminants from soils often are applicable to both ex situ washing and in situ flushing.

    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 ...

    For soil washing, contaminants sorbed onto fine soil particles are separated from bulk soil in a water-based system on the basis of particle size. The wash water may be augmented with a basic leaching agent, surfactant, or chelating agent or by adjustment of pH to help remove organics and heavy metals.
