Here are a couple noteworthy actions by the U.S. Environmental Protection Agency (EPA) related to per- and polyfluoroalkyl substances (PFAS):

·       The agency recently announced that it was adding five PFAS to its Regional Screening and Removal Management Levels, what EPA uses to determine whether further action is needed to protect human health.  EPA has set soil and groundwater protection screening levels for HFPO-DA (also known as GenX), PFOS, PFOA, PFNA, and PFHxS.  See Regional Screening Levels (RSLs) - What's New | US EPA.

 ·       EPA has extended its public comment period for its proposed Aquatic Life Criteria for PFOA and PFOS to July 2nd.  See Table 1 below for a summary and the May 3rd Federal Register Notice 2022-09441.pdf (govinfo.gov). 

In early May, the National Association of Clean Water Agencies (NACWA) joined in signing a letter to Congress asking for exemptions for public water utilities from the so-called Superfund law [NACWA Joins Congressional Letter Seeking PFAS CERCLA Exemption; Files Comments on EPA Permit with Monitoring Requirements].  EPA had previously announced its intentions and plans to develop a rule designating PFOA/PFOS as hazardous substances under CERCLA.
