Wastewater discharge reported in Ottumwa

The Cargill Meat Solutions Plant in Ottumwa reported a discharge from the plant into a storm sewer Monday night.

A short in a power panel caused process waste water to back up and bypass the industrial treatment system about 7 p.m. An estimated 20,000 gallons of untreated wastewater flowed into the storm sewer during the 12 minutes before a backup pump began operating.

The storm sewer flows into the Des Moines River.

The DNR will continue to monitor the situation.
