Sanitary overflows at sewage pumping stations in Catonsville, Essex and Eudowood were reported because of Wednesday's storm, according to the Baltimore County Department of Public Works.
Sites listed by the county include: Long Quarter Station on Dulaney Valley Road in Eudowood, the Frederick Road Station in Catonsville, and the Essex Pumping Station on Riverside Drive.
The public is advised to avoid contact with wastewater released at the sites. The Baltimore County Department of Health will monitor water quality and issue water contact advisories if necessary on its website: http://www.baltimorecountymd.gov/Agencies/health/environmentalhealth/watersampling/alertadvisory.html
As of 6 p.m. Thursday, no advisories had been issued.
All dumping stations, which were recently renovated or rebuilt, were overwhelmed by the magnitude of inflow and infiltration by the storm, the county said.
The Department of Public Works said the overflows, which began between 4 p.m. and 5 p.m. Wednesday, ceased at 11 p.m.
The largest overflow occurred at the station in Eudowood, where a 1.6 million-gallon overflow was estimated to have been discharged into the Loch Raven Reservoir.
An estimated release of 25,000 gallons of sewage was discharged at the Catonsville station into the Patapsco River, while 25,000 gallons was discharged into the Back River from the Essex station, the county said.Copyright © 2014, The Baltimore Sun
