HAMMOND | Environmental officials are investigating a glittery substance found Friday in Lake Michigan.
Dan Goldblatt, a spokesman for the Indiana Department of Environmental Management, said the department received a report Friday of the substance floating in the water between East Chicago and Burns Harbor.
He said investigators are trying to narrow down the possible source. A company removed the material from the water, and officials don't believe there are any health risks.
Hammond resident Jason Harris, of the Robertsdale neighborhood, said he spotted a glittery substance Sunday morning while walking his dog in the 2300 block of Indianapolis Boulevard. He saw the tiny silver material on cars and the sidewalk, he said.
Goldblatt said the department had not received reports of the substance in the air Sunday but would investigate if it was connected to the substance found in the water.
This weekend is not the first time there have been reports of a glittery substance in Northwest Indiana.
Earlier this summer, a metallic sheen was reported on Lake Michigan near Porter Beach. Initial test results showed the substance was an anti-caking agent used as a food additive and in industrial products.
A glittery substance in Robertsdale also was reported in June. Early reports indicated the material was identified as kish graphite, which is commonly used in the steelmaking process.
