SPRINGFIELD, Ill. (AP) - Illinois environment officials want state Attorney General Lisa Madigan to force a railroad company to clean up contamination from last week's freight-train derailment and explosion near Rockford.

One motorist was killed and several others injured trying to escape the ensuing explosions and fire after a 114-car Canadian National Railroad train derailed last Friday.

The Illinois Environmental Protection Agency says up to 75,000 gallons of ethanol leaked into the ground and a nearby creek.

The agency wants the railroad to clean up any contamination and supply residents with safe drinking water if wells are polluted.

Officials also believe the spill killed fish in nearby rivers. If confirmed, they want the railroad to restock the waterways.
