MARSHALL (WKZO) -- Four years ago this week Marshall became the site of one of the worst environmental disasters in U.S. History.
MSU Professor Steve Hamilton says it would be difficult to find any trace of the Enbridge oil spill today.
The work is mostly completed except for the barges and boats finishing up oil recovery operations and dredging in Morrow Pond. He says in a few weeks, that work will also be completed. .
Four years ago this weekend, the 6-B pipeline ruptured. Enbridge operators misinterpreted the pressure readings, according to an federal investigation of the spill, and kept the oil flowing.
By the time a utility crew investigating complaints of a natural gas smell discovered Canadian crude surging down Talmadge Creek the next morning and notified Enbridge, over 843-thousand gallons had escaped through the break in the pipeline.
Prof. Hamilton, who is based at the Kellogg Biological station, and served as a local expert on the river during the cleanup, says it was a billion dollar mistake.
That is how much Enbridge has paid so far to clean up the spill.
He says there will always be some oil out there, but he thinks the river is generally safe for recreational use. .
