Liquid wastes containing radioactive, hazardous, and regulated chemicals have been generated throughout the 40 years of operations at the US Department of Energy's (DOE) Hanford Site in southeastern Washington state. Some of these wastes were discharged to the soil column, and many of the waste components, including nitrate (NO{sub 3{sup {minus}}}) and carbon tetrachloride (CCl{sub 4}) have been detected in the groundwater of the unconfined aquifer at Hanford. The use of facultative anaerobic microorganisms is a promising technology for the ex situ and in situ removal of nitrates and organics from contaminated aqueous streams. This paper describes an ex situ biological process being developed at Pacific Northwest Laboratory for removal of NO{sub 3{sup {minus}}} and CCl{sub 4} from contaminated groundwater, and approaches for in situ denitrification and CCl{sub 4} biodegradation. 7 refs., 1 fig., 1 tab.
