    Further treatment of the soil through other more expensive treatment methods would then be necessary and the use of soil washing under these circumstances might not save any time or money. In general, soil washing is ineffective for soils containing more than 30 to 50% silt, clay or organic matter (Sharma and Reddy 2004, US EPA 1993).

    The soil-washing procedure developed by Makino et al. (2007) consisted of three steps: (1) chemical washing with appropriate chemical solutions, such as CaCl 2 and FeCl 3 to extract Cd from soils, (2) followed by water washing to eliminate the remaining chemicals, and (3) on-site treatment of the wastewater by a portable purification apparatus with a chelating material (Fig. 4.20).
