Low levels of PFAs found in water system serving Saginaw, Midland, others

AU GRES (AP) (2/23/2018) - Small levels of toxic flourochemicals have been found in a Lake Huron drinking water supply system that serves more than 260,000 people in dozens of Michigan communities.

The Michigan Department of Environmental Quality disclosed the discovery of per- and polyfluoroalkyl substances in the Saginaw-Midland Municipal Water Supply Corporation system on Wednesday. The system draws water from two points near Au Gres.

The concentrations are below the Environmental Protection Agency's health advisory level. Exposure to the chemicals has been linked to certain cancers, thyroid disorders, elevated cholesterol and other diseases.

The department didn't identify a source for the chemicals, but recommended that local officials begin considering treatment options. The department says more than 50 communities in seven counties take water from the system, including Midland, Saginaw and Bay City.

The same chemicals are the cause of widespread contamination on in the northern suburbs of Grand Rapids linked to shoe manufacturer Wolverine Worldwide dumping chemical waste. Private drinking water wells for hundreds of homes have been affected.
