What the agency says
In December 2023, the U.S. Environmental Protection Agency (EPA) requested comment on the proposed the Lead and Copper Rule Improvements (LCRI), which informed the revisions to the National Primary Drinking Water Regulation (NPDWR) for lead and copper. After consideration of public comment on the LCRI, and consistent with the provisions set forth under the Safe Drinking Water Act (SDWA), the EPA is finalizing revisions to the NPDWR for lead and copper. In this rule, the agency is finalizing requirements for drinking water systems to replace lead and certain galvanized service lines. The final rule also removes the lead trigger level, reduces the lead action level to 0.010 mg/L, and strengthens tap sampling procedures to improve public health protection and simplify implementation relative to the 2021 Lead and Copper Rule Revisions (LCRR). Further, this final rule strengthens corrosion control treatment, public education and consumer awareness, requirements for small systems, and sampling in schools and child care facilities. The final rule will significantly reduce the adverse human health impacts of exposure to toxic lead in drinking water.
