A bridge collapse in Iowa led to some fertilizer and diesel spilling into a river.
The Iowa Department of Natural Resources says the collapse occurred Friday morning on a private drive and it caused a fertilizer spreader to enter the Tarkio River near Stanton.
The operator was extricated from the machine and flown by medial helicopter to a trauma center for the treatment of serious injuries, according to the DNR.
Officials say an unknown amount of mono ammonium phosphate, sulfur, and potash spilled into the waterway.
