EPA Releases Guidance to Reduce Lead Exposure in Drinking Water
Reference source : US EPA
On August 21, 2026, the U.S. Environmental Protection Agency (EPA) released new guidance to help drinking water systems and states implement the Lead and Copper Rule Improvements (LCRI) and comply with existing requirements for lead service line replacement. The guidance provides clear definitions, practical information, and examples to support effective implementation.
New Implementation Resources
EPA finalized Access Tips and Service Line Inventory Tips to assist drinking water systems and communities in identifying and addressing lead service lines. The resources incorporate feedback received during the public comment period in April 2026.
Additional Lead Reduction Resources
EPA also updated its lead-related resources, including its lead website and the Lead and Children’s Health Story Map, which provide information for parents and caregivers, contractors, and health professionals. These resources complement EPA’s technical assistance and funding efforts to support lead service line identification and replacement. Nearly $3 billion in 2026 funding is available to support these activities.
Regulatory Background
Lead exposure can cause serious health effects, particularly in children, and there is no safe level of lead exposure. Lead service lines are a major source of lead in drinking water. The 2024 LCRI builds on the 2021 Lead and Copper Rule Revisions (LCRR) and the original 1991 Lead and Copper Rule (LCR).
Regulatory Significance
The guidance provides practical resources to support implementation of federal lead reduction requirements and assist states and drinking water systems in their efforts to identify and replace lead service lines.
