Immobilization processes in soil/waste systems impacted by hazardous wastes containing heavy metals were investigated. Samples of contaminated material (soil and/or waste) from nine sites in the Intermountain West and California included milling, electroplating, cement kiln dust, petroleum, and tailing and waste rock from mining operations. A sequential extraction procedure, originally developed to fractionate metals in sludge-amended soils into water soluble, mobile, and plant-available forms, was used to obtain preliminary identification of the leachable-metal fraction for the hazardous-waste-contaminated soils studied. Sorption kinetics and batch sorption/desorption studies were performed to determine the interaction of Cu and Cd, from an acidic leachate of a mine waste, with calcareous soils. Solid phase diagrams, exchange models, and GEOCHEM were used to define the mechanisms of metal attenuation of these soils.
