Strengthening Groundwater Protections from PFAS

The Minnesota Pollution Control Agency (MPCA) recently announced a draft wastewater permit for the 3M Cottage Grove facility, containing some of the strongest limits on PFAS in Minnesota history. 

PFAS are a large group of synthetic chemicals often used for their nonstick and grease- and water-resistant properties. These chemicals don’t break down and are found in a wide variety of products that end up in our state’s homes, workplaces, and waste streams. 

ASK MPCA TO SET STRONG PFAS REGULATIONS

The MPCA’s draft permit marks a major shift in PFAS regulation in Minnesota. It lowers allowable PFAS levels and includes stronger guidelines for monitoring groundwater, regular reporting, and community engagement and accountability from 3M. These provisions ensure that the Mississippi River and surrounding waters are safe for aquatic life and human activity. It also sends a clear message to 3M and other companies that they will be responsible for protecting our most valued resource.

Getting rid of PFAS has been a top priority for Conservation Minnesota for many years, and this new permit marks an important step towards controlling these forever chemicals. The health risks are well documented and widely known, and we expect our state regulators to keep us and our lakes and rivers safe. 

MPCA is currently accepting public comment on the proposal through August 30—this is an important opportunity to let the agency know the public supports these stronger limits and restrictions on PFAS. MPCA will host a virtual public meeting August 20.
