The absence of enforceable environmental and health standards for PFAS—a class of over 13,000 toxic, persistent, and bioaccumulative human-made chemicals—poses a severe and growing public health crisis. These “forever chemicals” are found in countless everyday consumer products, from non-stick cookware to clothing, and never break down in the environment. This widespread use and persistence means that PFAS contaminate our air and water, accumulate up the food chain, and are now detectable in the bloodstream of 99% of Americans. This exposure is associated with devastating health consequences, including cancer, birth defects, and damage to the liver, kidneys, and immune system, making urgent regulatory action a national necessity.
