Michigan Department of Environmental Quality officials are looking for chemicals in the Kalamazoo River near a city where residents are being given bottled water after contamination was found in their drinking water supply.
The Kalamazoo Gazette reports officials collected 36 water samples earlier this week upstream and downstream from the city of Parchment.
Sampling from the city's drinking water system found man-made chemicals called perfluoroalkyl and polyfluoroalkyl substances that were at levels 26 times greater than a lifetime federal health advisory
The substances are among chemicals referred to broadly as PFAS. They're used in manufacturing, firefighting and household and consumer products.
The Kalamazoo County Health and Community Services Department says test results from the samples are expected next week.
