EPA finalized revisions to the Lead and Copper Rule (LCR) to include a suite of actions to reduce lead exposure in drinking water where it is needed the most. The final rule identifies the most at-risk communities to ensure systems have plans in place to rapidly respond by taking actions to reduce elevated levels of lead in drinking water. The final LCR maintains the current Maximum Contaminant Level Goal (MCLG) of zero and the Action Level of 15 ppb. The rule requires a more comprehensive response at the action level and introduces a trigger level of 10 ppb that requires more proactive planning in communities with lead service lines. The revisions also include requirements for water systems to prepare an inventory of known lead service lines and to make the inventory publicly available. The final LCR takes a proactive and holistic approach to improving the current rule -- from testing to treatment to telling the public about the levels and risks of lead in drinking water. This approach focuses on the following six key areas: 1) identifying areas most impacted; 2) strengthening treatment requirements; 3) replacing lead service lines; 4) increasing sampling; 5) improving risk communication; and 6) protecting children in schools.
