This bill requires the Department of Defense to improve communication and transparency regarding PFAS contamination at military installations. It establishes a new office within the Pentagon to engage with communities affected by PFAS releases and requires the department to provide technical assistance and grants to help affected communities understand and participate in cleanup efforts. The legislation mandates that the Pentagon submit detailed budget reports to Congress consolidating all PFAS-related spending, submit biennial reports on testing and remediation progress at contaminated military sites, and have the Government Accountability Office conduct independent reviews of the department's cleanup efforts every five years. The bill applies to both current and former military facilities that have PFAS contamination and requires initial briefings and reports within 90 days to one year of enactment, though the specific funding amounts are not specified and will depend on future Congressional appropriations.
