The Lead-Free DC Omnibus Amendment Act of 2025 mandates the complete replacement of all lead service lines in the District of Columbia by December 31, 2030, prohibiting partial replacements and the installation of new lead, brass, or galvanized steel service lines. Property owners with lead service lines are required to enroll in the Lead Service Line Replacement Program or replace the lines themselves by October 1, 2024. The bill establishes protocols for testing service lines, public education requirements, and a prioritization schedule for replacements, particularly focusing on child development facilities and multi-unit residential properties. It also requires the Department of Energy and Environment to engage community-based organizations for oversight and sets penalties for non-compliance.

Additionally, the bill mandates that the District of Columbia Water and Sewer Authority (DC Water) implement a comprehensive Lead Service Line Replacement Program at no cost to property owners, maintain an inventory of service lines, and provide free water filters to affected residents. The legislation emphasizes community engagement and education on lead exposure risks, particularly for vulnerable populations. It includes provisions for annual reporting on replacement progress, establishes a nonlapsing Lead Service Line Priority Replacement Assistance Fund, and repeals several sections of existing law to streamline the replacement process. Overall, the act aims to protect public health by ensuring safe drinking water and eliminating lead exposure from service lines.
