The efficiency of air stripping for removal of volatile hazardous contaminants from soils is influenced by the water content of the soil being decontaminated. Control of soil water may be a valuable tool. Several factors must be considered, including the soil water content and porosity, dissolution, and adsorption on dry soil surfaces. A general model illustrating important considerations for design and operation of stripping systems is produced by representing soils as a four phase system. Example calculations have been made using benzene and 1,2-dichloropropane as the contaminants and three soils are given.
