Michigan Senator Gary Peters (D), Chairman of the Homeland Security and Governmental Affairs Committee, convened a hearing on December 9, 2021 to examine a recent report by the Inspector General for the United States Environmental Protection Agency regarding DOD’s knowledge of and failure to act regarding PFAS contamination in the military. The report alleges that DOD had knowledge of PFAS exposures among servicemen as of at least 2011 but waited until 2016 to take action. Richard Kidd, Deputy Assistant Secretary of Defense for Environment and Energy Resilience, testified that “we followed the lead of industry and our regulatory agencies,” which he described as “the accepted practice at the time.” Senator Peters accused DOD of not being “proactive in using” research he suggested showed potential hazards associated with PFAS. Additionally, DOD was questioned heavily on its practices regarding notification of those who were exposed and ramping up blood testing to monitor the effects of PFAS. DOD has taken action to limit PFAS found in firefighting foam (AFFF), but no further steps to identify other PFAS chemicals in military equipment.
