In July of 2010, an oil pipeline ruptured in Michigan spilling 1.1 million gallons of heavy crude into the Kalamazoo River.
Over two years and hundreds of millions of dollars have been spent cleaning up the river.

Do you think it can't happen? Enbridge pipelines have had a dozen leaks in the state of Michigan alone since 2003.
I walked along the river earlier this month:
