Perfluorochemicals (PFCs) and Minnesota Sites - EH: Minnesota Department of Health

Perfluorochemicals (PFCs) in Minnesota

Also referred to as Perfluoroalkyl Substances (PFAS)

The Minnesota Department of Health (MDH) and Minnesota Pollution Control Agency (MPCA) have investigated a number sites across the state where PFCs were released to the environment. 

In the eastern Twin Cities metropolitan region ("East Metro"), these sites include the 3M Cottage Grove manufacturing facility and large waste disposal facilities where PFC-bearing wastes were disposed. 

Statewide, MDH and MPCA have evaluated other places where PFCs may have been released to the environment, including: fire training facilities where special PFC-bearing fire-fighting foams (also called AFFF) were reportedly used, chrome plating plants, waste water treatment plants, and landfills. Although PFCs have been detected at many of these locations, most do not pose a risk to public health.

The MPCA also monitors PFCs in the general environment of Minnesota. This type of monitoring is referred to as ambient monitoring and you can learn more about it on the MPCA's website.

PFC Contaminated Sites in Minnesota:

Information about contaminated sites in Minnesota can be found on the MPCA website.

Due to the recent issuance of the EPA Health Advisory for PFOS and PFOA, MDH and MPCA will be conducting well sampling and other activities in the East Metro area. Visit the MDH Response to the EPA Health Advisory for PFOS and PFOA webpage for more information.
