Soil washing is a relatively low-cost alternative for separating wastes. The soil washing system can be operated as a closed treatment system permitting control of fugitive dusts and volatile emissions, an asset in securing public ac- ceptance. Compared with thermal processes, soil washing has a broad range of accept- able influent concentrations.
