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.

In 2008 and 2010, MDH conducted studies that measured PFCs in the blood of East Metro residents. These studies were designed to track PFCs in people who were exposed to polluted drinking water before the interventions.

In 2014, MDH will conduct the East Metro PFC3 Biomonitoring Project (PFC3 - more info (PDF: 388KB/2 pages)). The study will measure PFCs in the same people who participated in the 2008 and 2010 studies to check whether blood PFC levels have continued to go down following the public health interventions. It will also measure PFCs in people who moved to the East Metro recently, and therefore did not consume the polluted water, to see whether PFC levels in this group are similar to the U.S. population.
