"Massive Fertilizer Spill Wipes Out 750,000 Fish in Iowa Rivers"

A fertilizer spill in Iowa led to the death of an estimated 789,000 fish across a 60-mile stretch of rivers in Iowa and Missouri, causing one of the region’s most ecologically devastating chemical spills in recent years. The spill occurred when a valve was left open on a storage tank at an agricultural business, resulting in 265,000 gallons of liquid nitrogen fertilizer spilling into the rivers. The majority of the fish that died were small species, but larger fish, including catfish and carp, were also affected.
