Quantitative information on the immobilization of potentially health-hazard trace elements (e.g., Cd, Co, Cr, Cu, Ni, Pb, Zn, etc.) to prevent their migration through soil to water sources is scant. Little knowledge has been generated for the development of basic management practices for trace element stabilization against migration and their ultimate movement into domestic waters and potential food channels. The research here provides “baseline” information as a beginning for the control of hazardous trace element migration through soils. The contribution of 11 U.S. soils to the mobility of some common and trace elements as influenced by four readily characterized waste stream and leachate vehicles—pure water, dilute acid, solutions resembling industrial wastes, and municipal landfill leachates—is reported. Data are presented showing that: (a) soils release potentially hazardous constituents which migrate at different rates depending on certain measurable indigenous parameters, (b) solubilizing and mobility effects are a continuing process, (c) even the cleanest aqueous vehicle can become a carrier of potentially hazardous trace elements, and (d) certain characteristics of the soil, even under the most ideal conditions, must be identified before a management plan can be developed for the control of hazardous constituents in waste disposal.
