DeKalb County officials say the boil water advisory has been lifted in Dunwoody, which means that the entire county’s drinking water supply has been deemed safe.

“DeKalb County would like to thank our residents, business owners and visitors for their patience and cooperation during the boil water advisory,” CEO Michael Thurmond said in  a news release. “Thanks to the hard work of DeKalb County employees and efforts of the Georgia Environmental Protection Division, the county’s water system has returned to normal.”

Dunwoody was the only part of DeKalb County to remain under the boil water advisory implemented on Saturday. The alert was lifted for all other portions of DeKalb County on Sunday night after water samples taken at other county sites came back safe to drink.

Of the 30 sample sites, only the Dunwoody location required additional analysis before DeKalb County could lift the advisory entirely.

The county sent a news release at 4 p.m. on Monday saying the additional testing confirmed that the water in Dunwoody is safe.

The advisory was issued after thunderstorms Friday evening led to power outages at the Scott Candler water treatment plant in the northern part of the county. The power went out about 10:40 p.m. Friday and was restored by 2:30 a.m. Saturday, leading to a loss of water pressure.

“When this occurs, a potential health hazard may exist in these areas of zero pressure from backflow and/or back-siphonage of water of unknown quality into the water distribution system,” officials said in a news advisory.

All schools in the DeKalb County School District were open Monday on a normal operating schedule. Seven schools within the city of Dunwoody received bottled water, the district said in a tweet, and other precautions are being taken to ensure student and staff safety.
