Northern Minnesota seeks regional PFAS leachate-treatment capacity at Canyon campus

Representative Cal Warwas presented House File 573 to support expansion of the Canyon Integrated Solid Waste Management Campus near Virginia, Minnesota, to provide regional solid-waste management and on-site leachate treatment aimed at PFAS removal.

Dave Fink, director of environmental services for Saint Louis County, said the county has built a reverse-osmosis leachate system and plans an on-site treatment facility to manage PFAS in landfill leachate. He said the facility would serve the Northeast Minnesota region, treat leachate from active and closed landfills and prevent untreated leachate from entering receiving waters such as Lake Superior via the Saint Louis River. Fink said some landfills in the region currently send untreated leachate to wastewater plants that are not designed to remove PFAS.

Commissioner Mike Yukovich emphasized regional collaboration — seven counties and the Western Lake Superior Sanitary District are involved in planning — and framed the project as necessary to protect water quality. The county described contracting and the possibility of future joint-ownership arrangements; the plan anticipates treating a growing volume of leachate rather than shipping it to municipal wastewater plants that cannot reliably remove PFAS.

Committee members asked about regional cost-sharing and contracting approaches; Fink said initial revenue from contracts would help subsidize campus operations and that the project could evolve to a joint-powers ownership model. No formal vote was recorded during the March 17 hearing.
