Fluorochemical materials, also known as FC’s or PFC’s, have been detected at trace levels in some private and municipal wells in the East Metro area of St. Paul. These materials were formerly made by 3M and disposed of in some East Metro landfills decades ago.
3M has committed to conduct physical work at three of the former disposal sites (Oakdale, Woodbury and on-site at 3M Cottage Grove), even though the presence of these materials in the former landfills does not pose a risk to human health and the drinking water is safe.
The regulatory framework for each site is an agreed Consent Order signed by 3M and the Minnesota Pollution Control Agency (MPCA) in May of 2007. The Consent Order outlines 3M’s obligations regarding collecting data, presenting the data to the MPCA and the public and submitting proposed work plans for each former landfill. 3M also agreed in the Consent Order to provide the MPCA up to $8 million for the state’s work a former municipal landfill in the area (Washington County Landfill). The Washington County Landfill is managed by the MPCA under Minnesota’s closed landfill program and any work conducted there will be directly supervised by the MPCA.
Information relating to the projects to be conducted in Oakdale, Woodbury and 3M Cottage Grove can be found below.
