To direct the Secretary of Defense to designate a Coordinator for Engagement with PFAS-impacted defense communities.

HR 10166 requires the Secretary of Defense to appoint a Coordinator within one year of enactment to address PFAS contamination at military sites. The Coordinator will directly serve current and former defense communities in the U.S. affected by perfluoroalkyl and polyfluoroalkyl substances (PFAS) pollution. Key responsibilities include improving the Department's outreach and communication about PFAS contamination and acting as a dedicated point of contact between the Department, local governments, and affected residents. This bill creates a formal liaison role to enhance transparency and coordination during ongoing PFAS remediation efforts at military facilities.
