The purpose of the PFAS-Free Procurement Act of 2025 is to reduce the use of harmful chemicals known as perfluoroalkyl and polyfluoroalkyl substances (PFAS) in products purchased by government agencies. Specifically, it aims to prohibit the procurement of items that contain two specific chemicals: perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). The act also encourages agencies to prioritize the purchase of products that do not contain these harmful substances.
