Underground storage tanks emphasizing the single-shell storage tanks located at the Hanford site. | Groundwater, soil | Tank waste constituents ranging from Na-nitrates to trans-uranics, in 3 forms: supernatant (liquid), sludges, and salt-cake (which can be as hard as cement) | UST-ID is pursuing technologies in two general areas: characterization/ retrieval technologies & separations of low-level waste technologies. No/few specific parameters available | Integrated demo includes many technologies - no specific parameters given | Integrated demo includes many technologies - no specific parameters given | The UST-ID program will be used at Hanford, Fernald, Idaho, Oak Ridge, and Savannah River. Most UST waste was generated by processes used to separate nuclear fuels from other components. |

Characterization and treatment of contaminated Great Lakes sediment | Sediment | Organics and inorganics | Physical separation (mineral processing) technologies, including magnetic separation, gravity separation, and froth flotation, being investigated | Volume reduction followed by more expensive treatment | Physical separation is considered pretreatment, as some smaller amount of concentrated material will require further decontamination | Bureau of Mines bench-scale tests have identified potential for considerable cost savings. Most promising are grain-size separation and froth flotation. |
