The Military PFAS Transparency Act of 2025 aims to improve accountability and transparency regarding the Department of Defense's (DoD) actions related to perfluoroalkyl and polyfluoroalkyl substances, commonly known as PFAS. These substances are known for their harmful effects on human health and the environment. The law seeks to ensure that Congress and the public are informed about the funding, progress, and challenges associated with cleaning up PFAS contamination at military installations.
