STORM LAKE, Iowa (AP) — The Department of Natural Resources says a mechanical failure at a meatpacking plant caused thousands of gallons of wastewater to pour into Storm Lake in northwest Iowa.
The DNR says Tuesday the problem was noticed Monday night when employees of Tyson Fresh Meats discovered wastewater coming out of the ground outside a lift station. Workers determined a joint on the piping had failed.
The wastewater reached a storm sewer that empties into the lake near Awaysis Beach.
The city of Storm Lake posted warnings, discouraging swimming until Friday.
After discovering the discharge, Tyson and city officials worked to divert other wastewater to the city’s sanitary sewer system.
