Coal preparation refuse drainage from the high-sulfur waste of the Illinois Basin and from the low-sulfur waste of the Appalachian Region release acid and trace elements into surface and ground waters in concentrations that are environmentally unacceptable. However, water pollution can be controlled by calcining the refuse before disposal to immobilize refuse constituents, by neutralizing the waste with lime at the time of disposal, or by neutralizing refuse dump drainage with limestone, lime, or lye. The first method is more expensive and more effective than the other two. These conclusions were reached after laboratory analyses of coal waste from the high-sulfur coals of the Illinois Basin and from the low-sulfur coals of the Appalachian Region and of the waste leachates produced under simulated weathering conditions before and after treatment of the waste or leachate.
