Wolverine World Wide, a global shoe company based in Rockford, is under growing scrutiny after drinking water wells near an old dumpsite in Plainfield Township, Mich., were discovered to be contaminated with perfluorinated chemicals (PFCs), also known as polyfluoroalkyl substances (PFAS), which were used in the Scotchgarding process to make Hush Puppies at the company's tannery. Chris Hufnagel, vice president and head of corporate strategy at Wolverine, discusses the situation with MLive reporter Garret Ellison on Sept. 12, 2017.
