Proposed EPA rules require US cities to replace lead water pipes within 10 years

Most US cities would have to replace lead water pipes within 10 years under strict new rules proposed by the Environmental Protection Agency as the Biden administration moves to reduce lead in drinking water and prevent public health crises like the ones in Flint, Michigan, and, earlier, in Washington DC.

Millions of people consume drinking water from lead pipes and the agency said tighter standards would improve IQ scores in children and reduce high blood pressure and heart disease in adults. It is the strongest overhaul of lead rules in more than three decades, and will cost billions of dollars. Pulling it off will require overcoming enormous practical and financial obstacles.

“These improvements ensure that in a not too distant future, there will never be another city and another child poisoned by their pipes,” said Mona Hanna-Attisha, a pediatrician and clean water advocate who became an activist in Flint.

The Biden administration has previously said it wants all of the nation’s roughly 9m lead pipes to be removed, and rapidly. Lead pipes connect water mains in the street to homes and are typically the biggest source of lead in drinking water. They are most common in older, industrial parts of the country.

Lead crises have hit poorer, majority-Black cities like Flint especially hard, propelling the risks of lead in drinking water into the national consciousness. Their impact reaches beyond public health. After the crises, tap water use declined nationally, especially among Black and Hispanic people. The Biden administration says investment is vital to fix this injustice and ensure everyone has safe, lead-free drinking water.

“We’re trying to right a longstanding wrong here,” said Radhika Fox, head of the EPA office of water. “We’re bending the arc towards equity and justice on this legacy issue.”

The proposal, called the lead and copper rule improvements, would for the first time require utilities to replace lead pipes even if their lead levels aren’t too high. Most cities have not been forced to replace their lead pipes and many don’t even know where they are. Some cities with a lot of lead pipes might be given longer deadlines, the agency said.

The push to reduce lead in tap water is part of a broader federal effort to combat lead exposure that includes proposed stricter limits on dust from lead-based paint in older homes and childcare facilities and a goal to eliminate lead in aviation fuel.

The EPA enacted the first comprehensive lead in drinking water regulations in 1991. Those have significantly helped reduce lead levels, but experts have said they left loopholes that keep lead levels too high and lax enforcement allows cities to ignore the problem.

“We now know that having literally tens of millions of people being exposed to low levels of lead from things like their drinking water has a big impact on the population” and the current lead rules don’t fix it, said Erik Olson, an expert with the Natural Resources Defense Council who challenged the original regulations back in the early 1990s. “We’re hoping this new rule will have a big impact.”

Unlike other contaminants, lead seeps into drinking water that’s already left the treatment plant. The main remedy is to add chemicals to keep it from leaching out of pipes and plumbing fixtures. It’s hard. A home with dangerous lead levels can be next to a house with no lead exposure at all.

It will ultimately be up to utilities to decide whether to pay the full cost of replacing lead pipes, which is too expensive for many people to afford.

“We strongly, strongly encourage water utilities to pay for it,” Fox said.

The Association of Metropolitan Water Agencies, which represents large public water utilities, said it can be difficult to secure homeowner permission to do the work and handle rising costs.

A few communities have replaced pipes quickly. After crises in Benton Harbor, Michigan, and Newark, New Jersey, officials paid for and efficiently replaced lead pipes, adopting novel rules that required homeowners to let construction crews on to their property to do the work.
