A2: Environmental Cleanup
A Michigan Radio report looks at cleanup efforts of the MichCon site along the Huron River in Ann Arbor, where manufactured gas was made in the late 1800s and early 1900s by burning coal. The report quotes Kevin Lund, a senior geologist with the Michigan Dept. of Environmental Quality’s remediation division, regarding contamination in the river bed: “We were just collecting samples along the way and were finding exactly this all the way through here. And one of the locations that we dug, a hole in the bank, it filled with oil.” [Source]
