Water quality warnings on Antietam Creek were lifted Friday, two weeks after the City of Hagerstown's sewage treatment plant spilled water that had not been completely treated.
City Water and Sewer Department Manager David Shindle said he received clearance from the Washington County Health Department Friday morning to lift the three dozen posted signs, which were placed along the creek between Potomac River and the Frederick Street plant.
Wastewater treated at the plant goes into the creek.
On Aug. 13, the city's sewage treatment plant suffered an electric outage, causing the spill of between 3 million and 4 million gallons of water containing illness-causing bacteria found in human feces.
The spill is one in a series in past years linked to an aging treatment plant. City officials this week approved emergency spending measures to repair some of the problems, but there are several other long-term projects costing millions of dollars scheduled to tackle the problems.
