Chemical and physical interactions of an in situ oil-shale process (retort) water with a surface soil were investigated by soil and effluent analyses of three soil-column experiments whereby soil was leached with: (1) Distilled water, (2) a synthetic retort water containing only inorganic solutes, and (3) an actual retort water produced by in situ processing of oil shale. Major findings of this study include an ion exchange-precipitation reaction, in which exchangeable calcium in the soil is displaced by ammonium from retort water and precipitated as carbonate by inorganic carbon in retort water. This precipitation process affects soil permeability. Ammonium was strongly adsorbed from retort water by the soil, and was not removed by subsequent distilled-water leaching and drying. 26 refs.
