Defense Department claims new treatment technique a potential fix for PFAS-contaminated water
News
7 Nov 2019 | Military.com
"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."

Toxic PFAS chemicals can be dumped into Merrimack River, federal and state officials say
News
5 Nov 2019 | Boston Globe
The company’s tests showed that the amount of PFAS was more than 100 times higher than federal and state guidelines and more than 400 times higher than stricter standards being considered in Massachusetts. While the Lowell Regional Wastewater Utility treats the landfill runoff before discharging it into the river, the plant lacks the expensive equipment to filter out PFAS.
