The risk of source water contamination is becoming increasingly prevalent!
PFCs are a family of synthetic chemicals, initially developed by the 3M Company, that have been used for decades to make products that resist heat, oil, stains, grease, and water. Common uses include nonstick cookware, stain-resistant carpets and fabrics, components of firefighting foam, industrial applications, and coatings for packaging such as milk cartons, cosmetic additives, and other personal products.
n 2004 in Minnesota, PFCs were first found to have contaminated drinking water supplies in parts of the eastern Twin Cities.
Most of the contamination was traced to four dumps or landfills. From the 1950s through the early 1970s, 3M disposed of wastes from PFC manufacturing primarily in dump sites in Oakdale and Woodbury, at the 3M manufacturing facility in Cottage Grove, and at the Washington County landfill.
It has been apparent since 2006, however, that PFCs may be present at concentrations of potential concern in areas that are not related to the waste disposal sites.
People living in areas with PFC contamination are at risk.
