Swimmers were ordered out of Lake Michigan Monday in Northwest Indiana after an unidentified substance on the water’s surface left several kids with slimy or sticky feeling on their skin.
A strange dark sheen extended about a quarter mile along the Porter Beach area of the Indiana Dunes National Lakeshore. Authorities, including a hazardous materials team, were called to the scene and determined after initial testing that the substance was not oil, said Bruce Row, a ranger with the National Park Service.
A temporary swim ban was in place at the Indiana Dunes National Lakeshore and the Indiana Dunes State Park, Rowe said.
The U.S. Geologic Survey was also testing the substance. “Further results are expected Tuesday morning,” said Rowe.
There was no indication that Chicago beaches were affected based on information on the Chicago Park District website Monday night.
Park District officials were not immediately available for comment.
