Survey Results Reveal Exposure To PFCs In East Metro

MINNEAPOLIS (WCCO) -- The Minnesota Department of Health is releasing the results of their study on Perfluorochemical levels in the eastern Twin Cities metro area.

According to the health department's study, analysis confirms that some residents were exposed to PFCs in their drinking water.

"Participants who drank unfiltered water for more years had higher PFC blood levels," the health department reported. "Also, the more water a person drank, the higher their PFC levels were. These results confirm that drinking water was a major source of exposure in East Metro communities and that efforts to reduce this exposure were key in bringing down blood levels between 2008-2010."

PFCs were used for decades at 3M's Cottage Grove plant to make things like Scotchgard, non-stick cookware and firefighting foam. The PFCs were found to have contaminated groundwater and drinking water.

3M has said in the past that they believe there are no adverse health effects caused by PFCs.

More details will be released during a community meeting on Wednesday, May 15.
