Incinerators may spread, not break down PFAS
News
28 Apr 2020 | C&EN
New data suggest that commercial incineration of per- and polyfluoroalkyl substances (PFAS) doesn’t break down these hardy chemicals. Instead, it spreads them into surrounding areas.

EPA is abandoning those suffering from toxic PFAS pollution
News
26 Apr 2020 | The Hill
A year ago, the EPA promised Congress that, after years of stalling, it would finally move forward on regulation of two notorious ‘forever chemicals,’ PFOA and PFOS. The notice that eventually appeared in the Federal Register on March 10, 2020, however, is not a regulation; it is merely a proposal to consider regulation.
