PFC Biomonitoring in the East Metro - Minnesota Department of Health

PFC Biomonitoring: East Metro

Perfluorochemicals (PFCs) are chemicals that have been used for many years to make products that resist stains, grease, water, and heat.

In the mid-2000s, some public and private drinking water sources in the East Metro – a suburban area east of St. Paul– were found to be polluted with PFCs. Today, public health interventions have reduced PFC levels in drinking water to below health-based limits.

Since 2008, MDH has tracked blood levels of PFCs in people who live in the East Metro as directed by the Minnesota Legislature. Results are now available from MDH’s third PFC biomonitoring project – the East Metro PFC3 Biomonitoring Project – which tested blood levels of PFCs in over 300 East Metro residents.

This is a chart of the blood PFC levels in long-term East Metro residents compared to the US population in 2008, 2010 and 2014.

  • PFC blood levels are going down in long-term residents who were exposed to PFCs in drinking water before the public health interventions in 2006 (see above).
  • PFC levels in newer residents – who moved to Oakdale after the intervention – are similar to levels seen elsewhere in the U.S.
