Past disposal of volatile organic solvents has resulted in contamination of soils at U.S. Army installations. Technologies that involve volatilizing or air stripping contaminants from contaminated soils are used for remediation of these sites. The resulting stream of gaseous volatile organic compounds VOCs must be treated before the air stream is released to the atmosphere. Thermal treatment or carbon adsorption of gaseous VOCs is effective but expensive. The present study was conducted to evaluate the utility of using fixed populations of VOC-degrading microorganisms to destroy mineralize to inorganic products gaseous VOCs. This technology holds potential as a cost effective alternative or supplement to thermal treatment or carbon adsorption. The VOCs investigated include benzene, carbon tetrachloride, chlorobenzene, methyl ethyl ketone MEK, toluene, and trichloroethylene TCE.
