US EPA to investigate PFAS contamination from fluorinated containers

Discovery in pesticide packaging could mean wider problem, agency action

The US EPA has begun an investigation into per- and polyfluoroalkyl substance (PFAS) contamination associated with fluorinated plastic containers, in an expansion of its priority PFAS work that could prompt industry to explore alternatives.

The EPA’s research stems from the discovery of eight PFASs leaching from fluorinated high-density polyethylene (HDPE) containers into a mosquito control product inside, at small concentrations ranging from 20-50 parts per billion (ppb). But because this type of packaging holds many industrial chemicals regulated through TSCA and the Federal Insecticide, Fungicide and Rodenticide Act (Fifra), these findings could point to a broader problem.
