Mixed waste landfill In situ landfills in arid environments which contain complex mixtures Mixed wastes containing heavy metals in complex mixtures with organic, inorganic, and radioactive wastes Integration of existing technologies, including thermally enhanced vapor extraction system, flexible membrane lining system, and directional drilling Characterization and remediation technology demos Goal is to remove the most rapidly moving constituents, and to isolate the remaining constituents for 30 years (interim) or permanently. All of the characterization technologies currently funded by MWLID (Mixed Waste Landfill Integrated Demonstration) have been demonstrated.

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.

Borehole slurry extraction Soils, especially sand, stone, or clays Uranium, oil Soil is reduced in situ to a pumpable slurry. Single 6 to 12-inch diameter borehole Soil is reduced in situ to a pumpable slurry After treatment waste material is pumped back into cavity to prevent surface subsidence Application of 10 year-old borehole mining tool for extracting minerals to environmental problems.

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.
