Preliminary assessment of mixed hazardous and radioactive inactive waste sites at Hanford

In July 1986, The U.S. Department of Energy - Richland Operations Office (DOE-RL) and Pacific Northwest Laboratory completed a preliminary assessment of 337 inactive waste sites that were used between 1943 and 1980 to dispose of liquid and solid wastes to the soil column of the Hanford Site. The study, as reported here and in a draft report, was performed as the first phase of DOE-RL's Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) program and will be used to determine which sites should be further investigated and possibly remediated. It should be noted that, because the report is not yet final, some of the results could change
