Attacks on Lead Protections Threaten Nation’s Drinking Water

The Trump administration and certain members of Congress are trying to roll back protections for lead in drinking water. But there are ways to fight back.

There is no safe level of lead for anyone, and exposure to lead can cause irreversible developmental harm in children, as well as memory loss and reproductive impairment in adults.

Yet millions of families across the U.S. remain exposed to toxic lead in their drinking water.

What is Earthjustice doing?

Earthjustice has worked for years alongside our partners and clients to strengthen protections around lead contamination.

In 2024, our work helped compel the U.S. Environmental Protection Agency to mandate the replacement of most lead service water lines in the country within a decade. Congress then set aside billions of dollars to help pay for this widely popular investment.

Lead is Still in Our Pipes

There are over 8 million projected lead service lines in the U.S. — 8% of all service lines. Nearly half are found in Rust Belt states.

There are over 8 million projected lead service lines in the U.S. — 8% of all service lines. Nearly half are found in Rust Belt states.

What’s happening now?

The Trump administration and some members of Congress tried to gut these basic health and safety protections, threatening the drinking water of an estimated 22 million people across the country.

We will not cede any ground on the progress we’ve made.

What are “lead service lines”?

“Service lines” are pipes connecting your utility’s main water line to the plumbing system of houses, apartment buildings, and other structures.

If any part of the pipe is made of lead, it is a “lead service line.”

Lead service lines were commonly installed through the mid-20th century. Congress banned new lead service lines in 1986. But millions of existing lead service lines still remain today.
