Perfluorochemicals (PFCs) and Water
The chemical and physical properties of PFCs allow many of them to move very rapidly in the environment. Since they are able to easily pass through soil and fissures in bedrock, PFCs released to the environment can quickly contaminate the groundwater.
In the east metro area, the drinking water sources of eleven communities have been impacted by PFCs in the groundwater, including eight municipal water supplies (see Maps of Sites). In most cases, the concentrations of PFCs are far below levels of health concern.
Where PFCs exceed allowable levels, the Minnesota Department of Health (MDH) and Minnesota Pollution Control Agency (MPCA) have worked with the affected cities and homeowners to provide water treatment. MDH also contracted for an independent study of water treatment systems, to provide residents with information about how to reduce or remove PFCs from their water.
