EPA Announces New Lead and Copper Rule Improvements, Tightening Water Safety Standards
The U.S. Environmental Protection Agency (EPA) is requiring public water systems across the country to accelerate lead service line replacement and improve water testing protocols under final rules issued October 16, 2024, impacting millions of Americans.
The Lead and Copper Rule Improvements (LCRI) applies to all community water systems (CWS) – those serving at least 15 service connections or 25 year-round residents – and non-transient non-community water systems (NTNCWS). Key requirements include submitting an initial lead service line inventory, notifying customers of potential lead service lines, and ultimately replacing all lead and galvanized requiring replacement service lines by November 1, 2034. Water systems must begin submitting deliverables immediately, with the first major deadline being October 16, 2024, for the initial lead service line inventory.
Several deadlines are approaching in the next year. By July 1, 2025, systems must submit annual certification to state departments confirming customer notification and delivery of lead service line information. Annual repeat notifications to customers are required starting December 31, 2025, unless lead service connections have been fully replaced. A baseline inventory of all service lines and connectors is due November 1, 2027, alongside a service line replacement plan. These changes build upon previous regulations, including the 1991 Lead and Copper Rule and the 2021 revisions, aiming to address persistent concerns about lead contamination in drinking water, which can cause serious health problems, especially in children. More information about lead in drinking water can be found at the EPA’s website.
The EPA emphasizes that public water systems must continue to comply with existing regulations until the LCRI compliance date of November 1, 2027. Officials stated that these improvements are a critical step towards ensuring all communities have access to safe drinking water, and the agency will provide technical assistance to help systems meet the new requirements.

The EPA will continue to monitor implementation and provide guidance to water systems as they work to meet the new standards and deadlines.
