The U.S. Department of Energy has generated liquid wastes containing radioactive and hazardous chemicals throughout the more than forty years of operation at its Hanford site in Washington State. Many of the waste components, including nitrate and carbon tetrachloride (CCl 4 ), have been detected in the Hanford groundwater. In‐situ bioremediation of CCl 4 and nitrate is being considered to clean the aquifer. Preliminary estimates indicate that this technology should cost significantly less than ex‐situ bioremediation and about the same as air stripping/granular activated carbon. In‐situ bioremediation has the advantage of providing ultimate destruction of the contaminant and requires significantly less remediation time. Currently, a test site is under development. A computer‐aided design tool is being used to design optimal remediation conditions by linking subsurface transport predictions, site characterization data, and microbial growth and contaminant destruction kinetics.
