June 17, 2013 — Reports tonight suggest that inspectors investigating a substance from water along Lake Michigan’s shoreline could get lab test results Tuesday.
A park ranger says preliminary testing suggests that a residue in the water is not oil-based, though its chemical nature is under investigation after reports of an oily, metallic residue in water 125 yards off the shore at Michigan City. Reports indicate that hazardous materials staff are testing samples from that area, where the beach has been closed.
U.S. Coast Guard Petty Officer Troy Davis of Coast Guard Station 10 confirms the substance was reported just after 2 p.m. between the east pier-head in Michigan City and the beach at Mount Baldy. Davis says Michigan City sanitation workers are taking samples and a marine safety unit from Chicago is also in the area investigating.
