FREDERICK, Md. - Frederick County officials are trying to determine why a sewage treatment plant malfunction went unnoticed for 90 minutes.
The Frederick News-Post (bit.ly/Ng5baT) reports that 275,000 gallons of partially treated wastewater spilled into Ballenger Creek early Wednesday morning. The waste then flowed into the Monocacy (mah-NAH-kah-see) River.
County utilities chief Kevin Demosky says a pump-station control malfunctioned about 3:45 a.m. He says an alarm light and horn were supposed to alert the two employees on duty, but no one responded until 5:15 a.m.
Demosky says the spill was reported to the Maryland Department of the Environment and the county health department.
