PFOS

With much fanfare, the EPA announced the proposed drinking water regulations for two “forever chemicals,” PFOA and PFOS. EPA Administrator Michael Regan said, “Communities across the country have suffered far too long from the ever-present threat of PFAS pollution. That is why President Biden launched a whole-of-government approach to aggressively confront these harmful chemicals, and EPA is leading the way forward.”
The most recent scare by the Environmental Working Group (EWG) over PFAS in freshwater fish was picked up by CNN and all the major news organizations and presented as fact. But the EWG models skew the results. There are other ways that EWG uses deceptive means to reach its conclusions and deliver the scariest outcomes possible. 
“Eating one bass is equivalent to drinking PFOS-tainted water for a month.” Those are the words of Scott Faber, senior VP for government affairs at the Environmental Working Group. That is the message of a study by the EWG, carefully crafted to instill fear and drive regulatory science. It requires a carefully crafted response – here is mine.
The Environmental Protection Agency (EPA) is in the process of making a remarkable decision and one that will have repercussions throughout the US.  Its proposed safe levels in water for the “forever” chemicals perfluorooctanoate (PFOA) and its sulfonic acid (PFOS) are at extraordinary odds with other national authorities.
