A majority of states are considering new regulations to protect public health against PFAS, even as federal regulators walk back many of their protections. 

PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals used in products like nonstick cookware, waterproof clothing, food packaging, and firefighting foam. They’re often called “forever chemicals” because they don’t break down in the environment and can build up in the human body over time. Exposure to PFAS has been linked to cancer, immune system problems, and developmental issues.

Recently, the EPA signaled it may weaken national limits on PFAS in drinking water. In response, 36 states have proposed more than 250 bills in 2025 to better protect residents. These include banning PFAS in everyday products, setting stricter local water standards, and holding polluters accountable. In 2022, then Senator Sarah Elfreth and Delegate Sara Love successfully passed the George “Walter” Taylor Act, which banned PFAS in firefighting foam, rugs, and certain other products. During this past session, Senator Love and Delegate Stein proposed legislation that would limit PFAS concentrations in sewage sludge, often used as a cost-effective source of nutrients for farms. While that legislation ultimately did not pass, PFAS will certainly be a major issue during the 2026 legislative session.
