Minnesota Targets “Forever Chemicals” In Water With New Technologies

Minnesota aims to address a decades-old pollution problem by sucking harmful “forever chemicals” out of its groundwater using novel technology known as surface activated foam fractionation, or SAFF, according to an article from Wisconsin Watch. The Minnesota Pollution Control Agency, operating out of a shipping container at Lake Elmo’s Tablyn Park, reportedly hopes to process 60,000 gallons of water a day – removing the toxic per- and polyfluoroalkyl substances – or PFAS – and pumping the decontaminated water back underground.
According to Wisconsin Watch, the SAFF system strips a “chemical soup” from the water, which is then analyzed by scientists for more than 40 variations of PFAS. The funds for the nearly $800,000 technology reportedly come from a settlement the state struck with 3M in 2018 after suing the company over dumps it used for a chemical plant in the area.
