TLDR
A systematic evaluation of 3M and fluorotelomer-based AFFFs, commercial products, and AFFF-impacted groundwaters from 15 U.S. military bases was conducted to identify the remaining PFASs, finding 57 classes of novel anionic, zwitterionic, and cationic PFAss, most of which derive from electrochemical fluorination processes.
