Sawyer, S

An evaluation was performed of the International Waste Technologies (IWT) HWT-20 additive and the Geo-Con, Inc. deep-soil-mixing equipment for an in situ stabilization/solidification process and its applicability as an on-site treatment method for waste site cleanup. A demonstration was held at a General Electric Co. electric service shop in Hialeah, Florida. Conclusions were reached concerning the technology's suitability for use in cleanups of various contaminants and at different locations. The conclusions drawn from the available data are that: (1) immobilization of polychlorinated biphenyls (PCBs) appears likely, although due to low leachate concentrations for both the treated and untreated soils as a result of the low PCB concentrations in soil encountered in most of the tests, it cannot be confirmed; (2) heavy metals can probably be immobilized; (3) volatile organics can be reduced to low concentrations in treated soil leachates, but the ability to immobilize is not clear; and (4) a small volume increase on the order of magnitude of 5%-10% can be expected.
