JEFFERSON CITY — More than 50,000 gallons of untreated wastewater spilled into the Missouri River after an electrical failure at a Boonville wastewater lift station.
The state Department of Natural Resources says Boonville authorities reported the overflow Wednesday. Boonville officials believe a loose electrical connection at a station caused an electrical breaker to trip, shutting off power to the station's pumps.
Wastewater entering the station then backed up and began to overflow, eventually reaching the Missouri River. The city repaired the electrical problem and stopped the overflow on Tuesday.
The DNR is investigating to see if the overflow caused environmental damage.
