Toxic Delays Exposed—Pentagon Pushes 20 Years

The Pentagon quietly pushed back cleanup deadlines for toxic “forever chemicals” at nearly 200 military bases, some by as much as two decades, according to newly analyzed defense records.

Quick Take

A USA TODAY analysis found the Defense Department posted revised PFAS cleanup timelines in May, delaying target dates at close to 200 sites by up to 20 years.
The updated schedule was dated September 2025 and posted without a public announcement, according to lawmakers who later demanded answers.
At Naval Air Station Whidbey Island, investigators now don’t expect to finish even studying the contamination until 2038, before any actual cleanup starts.
The Defense Department says 723 installations need PFAS assessments, and 703 have already completed the first review stage.

Pentagon Records Show Widespread Delays

Hundreds of military bases have put off cleaning up toxic PFAS, or per- and polyfluoroalkyl substances, for years, a USA TODAY review of military records found. The newest round of delays appeared in an obscure part of the Pentagon’s website in May, even though the records were dated back to September 2025. Some target dates moved by as much as two decades.

PFAS chemicals come mostly from firefighting foam the military has used for decades during training drills. These “forever chemicals” don’t break down in nature and have been linked to cancer, liver damage, and other health problems. They often spread into groundwater and drinking water supplies near bases, putting both service members and nearby residents at risk.

Lawmakers Demand Explanations

Senators Kirsten Gillibrand and Gary Peters, along with several colleagues, sent a letter asking the Trump administration to explain the schedule changes. They said the new timeline, posted without public notice, pushed back cleanup work by more than a decade at many installations and by as much as two decades at others.

A Senate Homeland Security Committee letter from December added that the delays followed earlier reporting in September, which found the Pentagon had already stalled cleanups at nearly 140 sites for up to ten years. That letter pressed the Defense Department’s watchdog for a formal review of why the changes happened.

Some Sites Face Decades-Long Waits

At Naval Air Station Whidbey Island in Washington, officials now say the investigation phase alone won’t finish until 2038. That’s before any real cleanup work can even begin. Only one site, the Indian Head Naval installation in Maryland, has a longer timeline, stretching to 2042.

The Defense Department says the scale of the problem explains part of the slow pace. As of March 31, 2025, the agency had completed initial assessments at 703 installations. Of those, 586 are moving to the next legal cleanup step, while 117 needed no further action. Interim measures are planned for private wells found to be contaminated.

A Pattern That Predates This Administration

This is not the first time watchdogs have flagged slow progress. A 2021 review by the Environmental Working Group found the Pentagon had made almost no headway cleaning up some of the most contaminated Air Force and Navy bases, despite years of known pollution.

Cost is a factor too. The Pentagon estimates it will spend roughly seven billion dollars a year addressing PFAS contamination tied to firefighting foam the military still uses today. Critics argue that figure raises questions about spending priorities elsewhere in the defense budget while service members and nearby families wait for clean water.

Why This Matters to Everyday Americans

For families living near these bases, delayed timelines mean more years of uncertainty about their drinking water. This story cuts across political lines. Conservatives worried about wasteful government spending and liberals worried about environmental harm to communities both have reason to ask why cleanup keeps slipping further into the future.

The Defense Department has not published a detailed public explanation for why the September 2025 timeline moved so many deadlines back. Whether the delays reflect real technical hurdles or a lower funding priority remains an open question lawmakers say they intend to keep pressing.
