In a landmark effort to safeguard public health, the Environmental Protection Agency (EPA) has finalized a rule requiring water utilities to replace all lead service lines within the next decade. This decisive action aims to eliminate a persistent toxic threat that affects thousands of American children annually.

Despite being banned in new construction nearly 40 years ago, lead pipes still supply water to millions of homes across the United States. Lead exposure from drinking water is particularly harmful to children, causing irreversible developmental delays, learning difficulties, and behavioral issues. Adults are not immune; they face increased risks of high blood pressure, heart disease, kidney dysfunction, and cancer.
The initiative to replace these aging pipes is monumental, with projected costs reaching tens of billions of dollars. President Joe Biden has made this a top environmental priority, securing $15 billion through the bipartisan infrastructure law. So far, $9 billion has been allocated, sufficient to replace up to 1.7 million lead pipes. An additional $2.6 billion in funding was announced alongside the new rule.
Beyond replacing pipes, the regulation tightens the permissible lead levels in drinking water, lowering the enforcement threshold from 15 parts per billion (ppb) to 10 ppb. It also mandates the creation of a national inventory of lead service lines and requires testing for lead in schools and childcare facilities connected to public water systems.
Water utilities acknowledge the public health benefits but express concerns over the feasibility of the new requirements. Challenges include the substantial costs, the ambitious timeline, and the logistical hurdles of accessing private property to replace pipes.
Environmental advocates celebrate the rule as a significant victory. The EPA estimates that full implementation will protect up to 900,000 infants from low birth weight, prevent attention-deficit/hyperactivity disorder in up to 2,600 children, reduce premature deaths from heart disease, and prevent the loss of up to 200,000 IQ points in children.
“This is finally the strengthening of regulations to really follow the science and to put kids at the center of what needs to be done,” said Mona Hanna, a pediatrician who played a crucial role in exposing the Flint, Michigan, water crisis a decade ago.
