The group Public Employees for Environmental Responsibility has been one of many organizations repeatedly calling for class-based regulation that would see all PFAS facing restrictions.
“The more we learn, the more toxic we understand these chemicals to be,” said Kyla Bennett, who directs science work for PEER.
Bennett expressed support for looking at precursors and expanding regulations to chemicals beyond PFOA and PFOS. But she emphasized that a broader scope is needed, as well as uniformity.
PEER has been critical of the agency’s ranging definitions for the chemicals, which have been at odds with the definition used by the Organisation for Economic Co-operation and Development. That approach only instructs that one fully fluorinated methyl or methylene carbon atom be present within the compound.
