The U.S. Environmental Protection Agency (EPA) finalized a rule on Tuesday requiring the replacement of all lead drinking-water pipes within the next 10 years, a significant step to protect public health from the long-term effects of lead exposure. The new rule updates the Lead and Copper Rule and aims to eliminate the health risks tied to lead in drinking water.

This regulatory action follows the Bipartisan Infrastructure Law passed in 2021, which allocated $15 billion for lead pipe replacement. The updated rule enforces more stringent testing of water systems and lowers the threshold for action in communities to mitigate lead exposure.

Public Health Protection and Enhanced Transparency

EPA Administrator Michael Regan stressed the importance of the rule in addressing a persistent public health crisis. "For decades, we've known that lead exposure has severe impacts on children's health, yet millions of homes still receive drinking water through lead pipes," Regan said. "This administration is ensuring that no community, regardless of race or income, will have to worry about lead-contaminated water."

The final rule aims not only to eliminate lead pipes but also to improve communication within communities regarding the risks of lead in drinking water and the steps being taken to replace affected pipes. This transparency is crucial for public awareness and safety.

EPA Drinking-Water Pipe : Funding for Lead Pipe Replacement

Alongside the finalized rule, the EPA announced $2.6 billion in additional funding for drinking-water infrastructure. This funding, available through state revolving funds, will directly support lead pipe replacement efforts. Notably, 49% of this funding will be allocated to disadvantaged communities as grants or loan forgiveness, ensuring that low-income areas benefit from these upgrades.

Moreover, the EPA has allocated $35 million in competitive grants to further reduce lead contamination in drinking water, signaling the agency's commitment to safeguarding the health of all communities, especially those disproportionately affected.

EPA Drinking-Water Pipe : Longstanding Issue of Lead Exposure

The EPA estimates that up to 9 million homes still use lead drinking-water pipes, with many of these homes located in lower-income communities and communities of color. This has resulted in a disproportionate burden of lead exposure for these populations. The new rule is expected to significantly reduce these disparities.

Strengthening Existing Regulations

The finalized rule builds on the original Lead and Copper Rule, first introduced in 1991 and revised most recently in 2021. The latest improvements were initially proposed in November 2023 and are designed to enhance protections and expand the scope of the EPA’s regulatory framework on lead.
