Statute of limitations — Minnesota

Minnesota has a 6-year statute of limitations for personal injury claims from the date of discovery — among the most favorable in the nation.

6 years from discovery of injury and PFAS connection — very favorable

Filing venue

Where to File in Minnesota

Minnesota personal injury claims are governed by Minn. Stat. § 541.07, providing a 6-year limitations period from discovery for personal injury — very favorable for PFAS claimants. 3M Company's Oakdale and Woodbury manufacturing sites in Washington County contaminated the eastern Twin Cities metro aquifer system serving tens of thousands of residents for decades. The state's 2018 $850 million settlement with 3M was a landmark early PFAS resolution and demonstrates the state's willingness to pursue PFAS claims aggressively. Individual personal injury claims for PFAS-linked cancer remain available for residents of the affected zone.

Minnesota Department of Health established health-based values (HBVs) for PFAS in drinking water, with some limits as low as 10 ppt for individual PFAS — reflecting the state's advanced regulatory response to 3M's contamination history.
