Cleanup continues from a red diesel fuel spill into the Des Moines River last week.
The Iowa Department of Natural Resources says the focus of the cleanup is now on sandbars in the river in the downtown Des Moines area.
Fuel leaked from an emergency generator on the roof of Hy-Vee Hall on October 18th. It made its way into the storm sewer, which drains into the Des Moines River.
A company hired to clean up the spill initially used booms to keep fuel from traveling downstream. Now, sandbars near the Grand Avenue Bridge and the Martin Luther King Jr. Bridge are being targeted because it appears the fuel particles have collected on the sandbars.
The Iowa DNR says it will meet with the company to see if further cleanup is needed.
