INDUSTRIAL WASTEWATER DISCHARGE AT ROQUETTE IN KEOKUKWritten by Theresa Rose on August 25, 2015
KEOKUK – An estimated 500 gallons of industrial wastewater discharged Monday morning at the Roquette America, Inc. plant in Keokuk.
The discharge occurred between 9:15 and 9:30 a.m. when an expansion joint on a condensate pump failed, discharging the condensate to the Mississippi River.
The condensate may have contained ethanol and related compounds, but the concentrations won’t be known until sampling results come back from a laboratory.
The company quickly stopped the pump and repaired the pipe joint.
The DNR will continue to monitor the situation to determine if the discharge exceeded permit limits under the company’s national pollutant discharge elimination system (NPDES) permit.
