The overall goal of this subprogram is to develop effective methods for the treatment of chlorinated vola-
tile organic compounds (CVOCs) in the offgases produced by air sparg-
ing and vacuum extraction of con-
taminants (Video 6.0).

Atmospheric emissions of CVOCs at DOE facilities and throughout the United States will need to be abated in order to comply with the Clean Air Act Amendments of 1990. Current technologies for controlling atmospheric emissions of CVOCs include carbon adsorp-
tion, catalytic oxidation, and incineration.

Each of these control methods is best suited for particular condi-
tions (e.g., carbon adsorption is best suited for short-term, low-
mass flux applications, while in-
cineration is best for long-term, high-mass flux conditions). Cat-
alytic oxidation works well for conditions between these two extremes. However, carbon ad-
sorption is merely a transfer of
