At least 14 communities in Michigan have water contaminated with a family of chemicals known as per- and polyfluoroalkyl substances, or PFAS.
One of those sites, in West Michigan, has gotten a lot of attention recently. This month, the state abruptly announced a cleanup standard for PFAS.
But these chemicals have been a pollution problem in the state for years.
In Oscoda, some residents are wondering why remediation is taking so long.
