Exposure to lead through drinking water results primarily from the corrosion of lead pipes and plumbing materials. EPA's Office of Water (OW) promulgated the Lead and Copper Rule (LCR) to minimize the amount of lead in drinking water. The LCR requires water systems that are not able to limit lead corrosion through treatment to replace service lines (pipes connecting buildings to water distribution mains) that are made from lead. Water systems must replace the portion of the lead service line owned by the system and offer to replace the customer's portion at the customer's cost. When customers do not replace their portion of the service line, the situation is called a “partial lead service line replacement.” OW has requested the SAB to review and provide advice on recent studies examining the effectiveness of partial lead service line replacements. SAB's advice will guide EPA's determination of whether the scientific foundation for the regulatory requirement allowing the use of partial lead service line replacement may need to be modified in light of more recent scientific studies.
Federal advisory committees and panels, including scientific advisory committees, provide independent advice to EPA. Members of the public can submit comments for a federal advisory committee to consider as it develops advice for EPA. They should send their comments directly to the Designated Federal Officer for the relevant advisory committee.
