A boil-water advisory for most of north Atlanta Tuesday has been lifted.
Residents and businesses -- including Lenox Square and Phipps Plaza -- were asked to boil water used for drinking, cooking or preparing baby food because of a power outage at the city's Northside Pumping Station.
The power outage was caused by a tree that fell on one of Georgia Power's 115,000-volt electrical lines. Battery failure prevented the Pumping Station's emergency generator from functioning.
The power interruption took place at about 5:30 a.m. Tuesday and was restored approximately two hours later, city officials said. During the outage, water pressure dropped below 20 pounds, said Atlanta Watershed spokeswoman Susan Ross.
City officials sampled water from the system and tests revealed no contamination, allowing them to lift the ban at 12:35 p.m. Wednesday.
