EPA Finally Addressing Toxic PFAS Forever Chemicals

The U.S. federal government finally announced a plan on October 18, 2021 to take action on a ubiquitous* and currently lightly regulated class of chemicals that have been associated with a wide range of potential health risks**. The plan, published today by the Environmental Protection Agency (EPA), is designed to reduce human exposure to these toxic chemicals, known as PFAS. 

The new EPA plan lays out a series of steps the agency plans to take to help address widespread PFAS contamination. These include plans to:

  • Require PFAS manufacturers to conduct toxicity studies on a number of their products, with testing ordered by the end of this year
  • Set enforceable limits for levels of certain PFAS in drinking water by the fall of 2023
  • Review past EPA regulatory decisions on PFAS chemicals
  • More closely review the use of new PFAS
  • Publish toxicity assessments for commonly used PFAS known to affect human health
  • Designate certain PFAS as hazardous chemicals
  • Launch a number of initiatives to further study PFAS risks

*The production, use, and disposal of products containing PFAS means that these chemicals can be found in water, soil, and the air. See: Some 42,000 sources of “forever chemicals” could be polluting US water.  One study from the Centers for Disease Control and Prevention found PFAS in the blood of 97 percent of people tested. Yet there is currently limited or no toxicity data available for a large number of PFAS.

**There are approximately 5,000 PFAS—short for per- and poly-fluoroalkyl substances—with hundreds currently used to make nonstick cookware, water- and stain-resistant fabric, fire-fighting foam, and more. These chemicals are sometimes referred to as forever chemicals because they don’t naturally break down over time but just accumulate in the environment and in our bodies. And they can be hazardous to human health, according to a growing body of scientific research. Some of the better studied PFAS chemicals have been linked to certain cancers, weakened immune system response, decreased fertility, and other health issues.
