A rapid coliphage analysis technique for enumerating coliphages in natural waters has been evaluated by water quality laboratories located throughout the United States. Correlations were established between coliphages and coliforms in natural water systems. These correlations were highly significant. This relationship can thus be used to determine the number of fecal or total coliforms present in natural water samples based on an enumeration of coliphages. With this method, coliphages in natural water systems (containing greater than or equal to six coliphages per 100 ml) can be enumerated within 6 h.

Cunently available technology isnotadequate toassess environmental contamination at Department of Energy ('_.")E)sites, take permanentremedial action, and eliminate or minimize theenvironmental impact offuture operations. Technical resources toaddress these shortcomings exist within theDOE community andthe private sector, buttheinvolvement oftheprivate sector inattaining permanent andcost-effective solutions hasbeenlimited. During 1990, on behalf ofDOE's Office ofTechnology Development, ArgonneNational Laboratory (ANL) conducted a competitive procurement ofresearch anddevelopment projects addressing soil remcdiation, groundwater remediation, site characterization, and contaminant containment. Fifteen contracts were negotiated in these areas. Thisreport documents work performed as partof thePrivate Sector Research and Development Programsponsored by theDOE's Office ofTechnology Development within the Enviromental Restoration andWasteManagementProgram.The research anddevelopment work described herein was conducted under contract toANL. On behalf ofDOE andANL, Iwishtothank theperforming contractor andespecially the report authors fortheir cooperation andtheir contribution todevelopment ofnew processes for characterization andremcdiadon ofDOE's environmental problems. We anticipate that the R&D investment described here wiU berepaid many-fold inthe application ofbetter, faster, safer, and cheaper technologies. Details of theprocurement process and status reports forall15 of thecontractors performing underthis programcan be foundin"Applied Research and Development Private Sector Accomplishments-Interim Report" (Report No.DOE/CH-9216
