Gov. Maura Healey accused President Donald Trump’s administration of delaying the release of more than $50 million in “critical funds” for lead pipe replacement in Massachusetts.

The first-term Democrat from Massachusetts said the state has some of the oldest housing stock and water infrastructure in the nation and lead service lines “remain a threat to public health, especially for young children.”

“These funds stimulate our economy by creating construction jobs, replacing outdated infrastructure, and most importantly ensuring that residents are drinking safe, clean water. We urge the Trump administration to cease this dangerous delay in critical funding,” Healey said in a statement Tuesday morning.

A spokesperson for the U.S. Environmental Protection Agency said the agency is working to “expeditiously award funding to states under the longstanding State Revolving Fund programs to support lead service line replacements as well as drinking water, wastewater and stormwater infrastructure upgrades that are critical to local communities.”

The EPA announced in May 2024 — under the Biden administration — that Massachusetts would receive $50.1 million for cities and towns to help identify and replace lead service lines and prevent exposure to lead in drinking water.

But the Trump administration, according to Healey, delayed the allocation of the money as it conducts a review against a series of executive orders signed by the president. Healey said her administration has not received a timeline for when, or if, the funds will be released.

The money was supposed to head to the Massachusetts Clean Water Trust’s “Drinking Water State Revolving Fund,” a program designed to provide low-cost financing to help community public water suppliers comply with drinking water requirements, according to the Healey administration.

The program is administered by the Massachusetts Department of Environmental Protection.

Healey argued that the cash is intended to facilitate the removal of harmful lead from drinking water by “supporting public water systems for inventorying lead service lines and creating plans for the replacement of those lines.”

Attorney General Andrea Campbell, who has regularly sued the Trump administration this year, said lead pipes pose “serious health risks for Massachusetts residents, especially children and those living in poorer communities.”

“Since day one, I have advocated for federal funding to address this pressing public health issue, and I will continue to speak out against policies that put the health and safety of our residents at risk,” she said in a statement released by Healey’s office.

Trump and White House officials have regularly paused, delayed, or withheld funding from states as they review spending decisions against a flurry of executive orders the president has signed.

State Treasurer Deborah Goldberg, who chairs the Massachusetts Clean Water Trust, said the “thoughtless delay” puts people at risk.

“The federal funding we use addresses a critical health issue and allows us to invest in vital water infrastructure projects that directly benefit the people who need it most. Providing clean, lead-free drinking water should not be controversial,” she said in a statement.

The cash for lead pipe replacement is not the first Massachusetts-bound money to be held up under Trump.

The president cut more than $12 million earlier this month to provide locally-sourced food to school children in Massachusetts, a move that drew rebukes from local elected officials.

The Trump administration is also attempting to cut funding for medical research by reworking a policy that caps additional grant money that institutions receive for indirect costs associated with projects.

That decision, which is the subject of a court challenge, could affect more than $200 million in federal dollars for Boston Children’s Hospital, top executives at the medical facility have said.
