Using publicly available information from the Environmental Protection Agency (EPA), EDF estimated that fully replacing the 9.3 million lead service lines (LSL) in 11,000 community water systems (CWS)[1] across the country would yield societal benefits of more than $205 billion, or about $22,000 per LSL removed. This estimate is based solely on reducing lead exposure in adults in order to have fewer cardiovascular disease (CVD) deaths over 35 years. It does not include the benefits to children’s brain development.
We submitted our analysis in comments to EPA on its proposed revisions to the Lead and Copper Rule (LCR), the federal regulation that limits lead in drinking water. Given the magnitude of the benefits, we called on the agency to incorporate CVD mortality into its economic analysis and consider strengthening its proposal by requiring full LSL replacement as an integral part of every CWS’s efforts, instead of as a last resort when lead levels get too high.
