Lead Sites Workgroup (LSW)

Established in August 1996, the LSW consists of remedial project managers (RPMs) and Resource Conservation and Recovery Act (RCRA) project managers, toxicologists, and representatives from EPA Headquarters. The goals of the LSW are to identify and resolve key issues on lead response decisions and provide updated guidance for addressing lead sites in a nationally consistent manner. The LSW also develops guidance and position papers that clarify national policy or address issues lacking clear policy regarding response to lead contamination at Superfund sites. Additionally, the LSW provides consultation to remedial project managers (RPMs) and Resource Conservation and Recovery Act (RCRA) project managers, upon request, to advise on unique or precedent-setting site-specific issues.
