WASHINGTON, D.C. – Today, U.S. Senator Cory Booker (D-NJ) joined a group of 27 Senate Democrats led by Senator Kirsten Gillibrand (D-NY) demanding that the Trump administration reverse its decision to delay the cleanup of toxic chemicals at military installations across the country and take action to protect military families and nearby communities by addressing contamination at the affected sites.

In a letter to Secretary of Defense Pete Hegseth, the Senators called on the Trump administration to immediately restore the previous timetable for remediating per- and polyfluoroalkyl substances (PFAS) contamination at U.S. military bases and to reverse plans that would further delay long-overdue cleanups.

“For years, communities contaminated by PFAS from nearby DOD installations in our states have waited for the DOD to take action. We request that the Department reverse its decision, return to the previous timetable released in December 2024, and accelerate efforts to remediate confirmed PFAS contamination,” the Senators wrote.

At least 700 military sites in the United States are known or suspected to have PFAS contamination from DOD activities. DOD’s delayed timetable would postpone cleanup efforts at approximately 150 of them, in some cases for nearly a decade, including Joint Base McGuire-Dix-Lakehurst in New Jersey, which would experience a nearly 6-year delay. Specifically, DOD pushed back the time frame of the Remedial Investigation/Feasibility Study (RI/FS) phase for these bases, which involves collecting detailed information on the nature and extent of the PFAS contamination and conducting a study to evaluate potential options for cleanup.

PFAS chemicals are widespread contaminants found in many industrial applications and especially around U.S. military installations. PFAS exposure is linked to an array of health problems, including various cancers, reduced immune function, reproductive challenges, birth defects, thyroid issues, and more. The use of PFAS-containing firefighting foam at Department of Defense (DOD) facilities, and the subsequent stormwater runoff, is a significant source of drinking water pollution. This contamination poses serious health risks to service members and their families, as well as surrounding communities.

Senators Booker and Gillibrand were joined on the letter by Senate Democratic Leader Chuck Schumer (D-NY) and Senators Angela Alsobrooks (D-MD), Michael Bennet (D-CO), Richard Blumenthal (D-CT), Tammy Duckworth (D-IL), Dick Durbin (D-IL), John Fetterman (D-PA), Maggie Hassan (D-NH), Martin Heinrich (D-NM), John Hickenlooper (D-CO), Mark Kelly (D-AZ), Andy Kim (D-NJ), Angus King (I-ME), Ben Ray Luján (D-NM), Jeff Merkley (D-OR), Jon Ossoff (D-GA), Alex Padilla (D-CA), Gary Peters (D-MI), Jacky Rosen (D-NV), Bernie Sanders (I-VT), Brian Schatz (D-HI), Adam Schiff (D-CA), Jeanne Shaheen (D-NH), Elissa Slotkin (D-MI), Chris Van Hollen (D-MD), and Ron Wyden (D-OR).
