Overview

Per and polyfluoroalkyl substances (PFAS)1 are a group of manmade fluorinated compounds which are used for a variety of applications by both industry and residential households. These chemicals are widely used because they are resistant to heat, water, and oil. PFAS are commonly found in every American household, and in products as diverse as non-stick cookware, furniture, clothing, cosmetics, lubricants, paint, carpets, pizza boxes, popcorn bags, and many others. Although there is some evidence that exposure to PFAS at certain levels can lead to adverse health outcomes in humans, health outcomes are still largely unknown. Several recent legislative and regulatory efforts across the US to address PFAS have focused on limiting levels in drinking water as policy makers act to minimize human interaction with these chemicals. Unfortunately, many of these actions have not followed the usual scientific and public review process for addressing chemicals of concern.
