EPA to Require PFAS Manufacturers to Provide Toxicity Data

January 24, 2022 – On December 28, 2021, the U.S. Environmental Protection Agency (EPA) granted a petition to compel per- and polyfluoroalkyl substances (PFAS) testing by companies. 

PFAS are a group of manufactured chemicals that have been used in products since the 1940s. For a long time there was minimal to no oversight of testing into the potential harmful effects of these chemicals. In effort to improve the understanding of and to protect people from the potential risks of PFAS, the EPA has made the decision to require companies to test for these harmful chemicals.    

The EPA plans to require PFAS manufacturers to provide toxicity data for all the various categories of PFAS. The agency is expected to utilize its TSCA section 4 order authority to mandate these test orders and to fund the studies.  

In October 2021, the EPA announced its National PFAS Testing Strategy and outlined the various phases behind PFAS testing. The granting of this petition is the first step towards a wider understanding of PFAS. 

Below is a list of items the EPA has announced as related to this PFAS testing and will be related to the future development of this initiative.  

• Near-Term Testing Covers 30 of 54 Petition Chemicals 
• Subsequent Testing May Cover nine of 54 Petition Chemicals 
• Remaining 15 of 54 Petition Chemicals 
• Mixtures Studies 
• Human Studies 
• Analytical Standards
