July 2010, more than a million gallons of tar sands crude spilled into Michigan’s Kalamazoo River. This is the largest inland spill in US History. A fired cleanup worker with a dark past claims he was ordered to cover up oil to meet federal deadlines. His case went to trial last week.

Even today two years later, one can still scoop up handfuls of Tar Sands Oil from the marshlands surrounding the river. The communities living around the river are still sick with nerve damage and other illnesses related to the chemicals diluting the Tar Sand Oil. Enbridge still claims the river is clean.
