The U.S. Bureau of Mines developed a method to treat lead-contaminated soil and ebonite battery casing wastes to produce a nonhazardous material. The cleanup procedure involves wet screening to separate a minus 18-mesh soil fraction; removal of metallic lead, rocks, wood, etc.; carbonation to change lead sulfate to acid-soluble lead carbonate; size reduction; acid leaching; and rinsing. Treated casing wastes and soils pass the Toxicity Characteristic Leaching Procedure (TCLP) test and can be reclassified as nonhazardous materials. Based on this process, a conceptual pilot plant has been designed which will be demonstrated on wastes from two Superfund sites.
