Abstract Per‐ and polyfluoroalkyl substances (PFAS) are a broad group of persistent organic compounds with vastly differing physicochemical toxicological properties. Some jurisdictions have proposed to regulate PFAS as single class overcome the limitations regulating such diverse on chemical‐by‐chemical basis. Implications been discussed for production use, but equivalent discussion implications managing contaminated sites is largely lacking. This opinion piece summarizes views environmental consultants, regulators, land managers, academics significant experience in researching or PFAS. The considered that neither approach nor well suited risks from site setting, defining subgroups would value. Second, some not all group, hypothesize properties drive fate transport those influence toxicity bioaccumulation animals. may be valuable observation future discussions dividing into subclasses regulation based rather than purely structural definitions.
