Description:
Chlorinated solvents such as tetrachloroethylene, trichloroethylene, carbon tetrachloride, chloroform, 1,2-dichloroethane, and dichloromethane (methylene chloride) can exist in contaminated subsurface material as (1) the neat oil, (2) a component of a mixed oily waste, (3) a solution in soil water, or (4) a vapor in soil air. Spills of such materials to subsurface material are frequently treated by soil vacuum extraction to remove volatile oils and vapors in soil air, or by air stripping of contaminated ground water. Both physical treatment processes produce a waste stream of contaminant vapors in air. At present, these wastes are discharged to the atmosphere, or treated with activated carbon, catalytic combustion or incineration.
