“Unfortunately, we have only begun to explore the extent of the PFAS problem,” said Patrick MacRoy, the deputy director of the Environmental Health Strategy Center. “Relatively few water supplies in Maine have been tested, and the state has yet to test most of the agricultural lands that were contaminated by PFAS-laden sludge. In addition to polluting the groundwater, this contamination may also be contaminating crops and animal feed, allowing PFAS to enter our food supply. The state must take aggressive action to uncover where we are being exposed to PFAS.

"This is the only technology that actually destroys PFAS molecules that has been demonstrated at this scale; it doesn't just remove them from water," added Clarkson's Dr. Tom Holsen, also a principal researcher, in the release. "All of the other demonstrations that we're aware of remove it from the water through filtration so there is still a PFAS containing waste."
