This bill mandates the Secretary of Defense to designate a Coordinator for Engagement with PFAS-impacted Defense Communities within one year of the Act's enactment. This new role aims to enhance the Department of Defense's interaction with communities affected by perfluoroalkyl and polyfluoroalkyl substances (PFAS) contamination. The Coordinator's primary responsibilities include improving the Department's outreach, education, and communication efforts for current and former defense communities in the United States impacted by PFAS. Furthermore, the Coordinator will act as a dedicated liaison between the Department and local governments, advocacy organizations, and individual citizens in these communities, particularly where the Department has ongoing or incomplete PFAS remediation projects.
