Cottage Grove, Minnesota: 3M PFAS Contamination and Your Legal Rights If you live in Cottage Grove, Woodbury, Oakdale, Lake Elmo, or anywhere along the east metro corridor of the Twin Cities, you have been hearing about 3M and PFAS for years. You may have shrugged it off, trusted the water filters, or assumed the 2018 settlement fixed it. On May 1, 2026, the Minnesota Pollution Control Agency filed a new lawsuit saying the contamination is still happening — at concentrations as high as 310,000 parts per trillion in some locations, a number so far above the federal safety limit that it changes the conversation from “is the water safe?” to “who is going to be held accountable for what it already did to my family?” We are Attorney911 — The Manginello Law Firm, PLLC. We handle toxic tort and environmental contamination cases, and we built this page for one person: the east metro resident who just read the headline, turned to their spouse, and said, “Could this be why?” Maybe why the kidney cancer.

Cottage Grove PFAS Contamination: Minnesota’s New Lawsuit Against 3M and What It Means for Your Family If you live in Cottage Grove, or Woodbury, or Oakdale, or any of the east-metro communities that sit on the same groundwater aquifers that 3M’s chemical plant has been sitting on for seventy years, you already know this story. You have been hearing about PFAS — “forever chemicals” — for over a decade. You watched the state sue 3M in 2010. You watched the $850 million settlement in 2018. You watched 3M disclose a previously undisclosed chemical release in 2020. You may have had your water tested, or switched to bottled water, or installed a filtration system. And now, in May 2026, you are reading that the Minnesota Pollution Control Agency has filed a new lawsuit — alleging that 3M’s Cottage Grove plant is still releasing PFAS into groundwater and the Mississippi River, that hazardous waste containers were never removed, and that a $300 million treatment system does not actually stop contaminated water from reaching the river. Here is the single most important thing this page will tell you: the state’s lawsuit does not compensate you. It seeks civil penalties, cleanup costs, and natural…
