Lead and Copper

Background Overview
In 2021, the Environmental Protection Agency (EPA) released Lead and Copper Rule Revisions (LCRR) requirements that public water systems must comply with starting on October 16, 2024, as outlined in the Lead and Copper Improvement (LCRI) proposal. These requirements include the initial service line inventory, notification to persons served of known or potential lead service line, Tier 1 public notification of a lead action level exceedance, and associated reporting requirements.

The Lead and Copper Rule (LCR) protects public health by minimizing lead and copper levels in drinking water, primarily by reducing water corrosivity. Lead and copper enter drinking water mainly from plumbing materials containing lead and copper. All community water systems (CWSs) and non-transient non-community water systems (NTNCWSs) are subject to LCR requirements.
