PFAS (per- and polyfluoroalkyl substances) is the preferred abbreviation used to collectively describe PFOA, PFOS, and other chemicals in this group. PFAS were previously referred to as PFCs.
3-page general update on (then current) status of the MPCA’s work on PFAS.
Investigation of PFAS in ambient environment, distribution of PFAS in environment, exposure and effects on humans and wildlife, outlook
Scientists have found that PFAS may cause long-lasting environmental contamination, including uptake into humans’ bodies. Of particular concern is the possibility that PFAS in Class B firefighting foam may be able to travel from a fire training area to municipal or private wells.
Center for Environmental Health’s Report on avoiding hazards and safe purchasing of food ware: For institutional purchasers of food ware. This report focuses on the use of fluorinated compounds in disposable food service ware. Offers recommendations and resources to help purchasers procure safer food ware products and equips purchasers with tools to push manufacturers away from these harmful compounds and towards safer products.
Lakes – fish
- 2008 MPCA Metro Lakes PFC Fish Data, 15 lakes
Chart: Average PFOS concentrations in bluegill, bass, pike, crappie, pumpkin seed fish
- 2007 MPCA Metro Lakes PFC Fish Data - First 10 of 30 Lakes
Data charts for PFAS concentrations found in fish in 10 metro-area lakes
- 2007 MPCA Metro Lakes PFC Fish Data – additional 20 lakes
Reporting of PFAS in fish in additional metro-area lakes. Data shows mixed results, from elevated PFAS levels to no detection. Variations likely due to stormwater runoff from varied land uses.
- Summary of PFC Testing at Landfills
Chart: Results of groundwater and leachate sampling conducted at about 40 landfills across Minnesota. The results show that PFCs are found in groundwater and/or leachate at a number of active landfills, many of which don’t have a history of accepting wastes related to the 3M Company’s manufacture of PFCs. Questions about the survey can be directed to Mark Rys at the MPCA, 651-757-2685.
