ABSTRACT
Degradative solidification/stabilization (DS/S) is a potential new technology to remediate sites contaminated with chlorinated hydrocarbons or mixtures of chlorinated hydrocarbons and inorganics such as heavy metals. Experimental studies were conducted to screen a wide range of reagents that could be used to treat chlorinated hydrocarbons. Tetrachloroethylene was used as a model chlorinated hydrocarbon. The screening experiments tested a total of 36 systems that included combinations of different types of binders, electron donors, and electron carriers. A combination of ferrous iron and Portland cement was identified as a potentially effective DS/S system for chlorinated hydrocarbons.
