One-thousand gallons of sugar water was reportedly released into the Mississippi River at Keokuk, Iowa.
A statement from the Iowa Department of Natural Resources said the spill happened at 11 p.m. Thursday, August 1, 2013 when a sugar water tank overflowed at the Roquette America refinery at 1003 South Fifth Street.
The facility shut down at 11:07 p.m. to halt the sugar water release. Operator error was blamed for the overflow.
The spill was reported to the Iowa DNR at 6 am. Friday, August 2. The DNR did not issue any precautionary statements or health alerts because of the spill.
The Keokuk bio-refinery facility primarily processes corn into food and non-food products.
