EPA’s Science Advisory Board (SAB) Drinking Water Committee will meet March 30-31 in Alexandria, Va., to review technical studies examining the effectiveness of partial lead service line replacements (PLSLR) in reducing lead levels in drinking water. The SAB will examine studies and make recommendations on five specific issues: the associations between elevated blood lead levels and PLSLR; the effectiveness of PLSLR in light of tap samples conducted before and after partial replacements; the effectiveness of PLSLR compared with full lead line replacements; whether a standard operating procedure (SOP) should be developed to minimize lead level spikes following PLSLR; and whether PLSLR SOPs should include steps to address concerns about galvanic corrosion.
Additional information, including a copy of the charge to the committee, is available online.
