Friday was the second day of a boil water advisory for downtown Atlanta and several parts of South Fulton County.

That means residents and pets in the highlighted area were told not to not drink tap water before bringing it to a rolling boil for at least one minute.

Part of that advisory included part of Hartsfield-Jackson International Airport. The airport's spokesperson said it took precautions to keep travelers and employees safe.

Restaurants inside the airport brought in bagged ice, water fountains were disconnected and signs were placed on restrooms doors alerting of the advisory. Reese McCranie, a Hartsfield-Jackson Airport spokesperson, said travelers were allowed to use the restrooms and wash their hands.

A power outage at the Hemphill water treatment plant in NW Atlanta prompted the water warning.

By Friday afternoon, the advisory had been lifted for much of the affected areas.
