The Bureau of Mines, under several interagency agreements with the EPA, has successfully developed a process to remove the lead contamination from lead-acid battery breaker sites. The cleaned materials can pass the requirements of the EPA's EP toxicity or TCLP test with <500 ppm Pb remaining in the soil and battery casings. The choice of acid would depend on the economics, the ability to clean the waste acid streams to the discharge limits, and the type of lead product desired. At completion of the cleanup at a particular site, lead would be removed from the waste streams prior to discharge to meet the limit of 50 ppb, first by pH adjustment to remove most of the lead and then by polishing methods such as ion exchange or precipitation.
