GARY, Ind. (AP) — Federal and state officials are investigating an apparent oil leak that's left a petroleum sheen on a major drainage ditch in northwestern Indiana.
Lake County Surveyor George Van Til said Thursday the sheen on the surface of Cady Marsh Ditch doesn't appear to be a major spill from any of the area's petroleum pipelines.
Van Til tells The Times of Munster the waterway that flows through Griffith, Highland and Munster is an important drainage ditch and if the situation becomes serious it could ultimately affect the Little Calumet River and even Lake Michigan.
He says the U.S. Environmental Protection Agency, state officials and local hazardous material teams are trying to stem the flow of oil and locate the source, which may be a deteriorated underground tank.
