An advisory issued this weekend to boil water for at least one minute before using it for cooking, drinking or personal hygiene was removed for one city block, the Atlanta Department of Watershed Management said.

The advisory ended Tuesdayjust before 3:30 p.m. for residents in the 745 block of Memorial Drive. It was orginallyin effect until 6 p.m. The department advised customers within the boundaries of Memorial Drive, Chastain Street, Pearle Street and Interstate 20 to run faucets for three to five minutes to clear the water lines. Infants, the elderly and those with immune deficiencies were urged to be particularly careful in that area.

The advisory, which originally affected parts of downtown, southeast and southwest Atlanta, followed major storms that created electrical power outages. Those outages resulted in a temporary loss of pressure in the drinking water system at two pumping stations.

The Department of Watershed Management flushed its system as a precaution to ensure no contamination existed.

“Samples taken throughout all other affected areas showed no contamination,” department spokeswoman Lillian Govus said.

The advisory was lifted at 2 a.m. Monday for downtown Atlanta and Avon Avenue to the south, Holtzclaw Street to the east and Joseph E. Lowery Boulevard to the west, according to the Department of Watershed Management.
