The Clean Water Standards for PFAS Act of 2025 aims to improve water quality by setting strict guidelines and standards for harmful chemicals known as perfluoroalkyl and polyfluoroalkyl substances (PFAS). These substances are often found in various industrial processes and can contaminate water sources, posing health risks to humans and the environment. The key provisions of this legislation include the establishment of water quality criteria for PFAS, which the Environmental Protection Agency (EPA) must publish within three years of the law's enactment.
