Summary:One of the major causes for concern in the landfilling of heavy metal sludges is the potential for acid leaching. In this paper the Chemfix waste-form is described, which, because of its low permeability, high buffer capacity against acid leaching and its clay-like structure and properties, can be used to stabilize heavy metal sludges for landfilling. A simple model is developed and used to investigate the values of the various parameters involved in the product design. It is shown that for barrier lifetimes orders of magnitude in excess of those expected for conventional cut-off walls and liners should be possible.—Modified journal abstract. [C.N.]
