Officials at Atlanta's Hartsfield-Jackson International Airport advised travelers to avoid drinking water from the airport's water fountains and faucets out of an abundance of caution on Friday.
In a series of tweets published Friday morning, the airport cited a temporary boil-water advisory from the city of Atlanta for the warning and urged travelers to avoid ice and coffee machines as well.
The advisory went into effect Thursday and the city was expected to receive water testing results at some point Friday, according to The Atlanta Journal-Constitution.
"Customers in these areas should boil water for one minute past a rolling boil before using it for cooking, drinking or brushing teeth," the advisory states. "Infants, the elderly and those with immune deficiencies should be particularly careful."
"The boil water advisory is a precautionary measure for consumption," a Department of Watershed Management spokeswoman told the Journal-Constitution in an email.
"We have not deemed there to be any contamination, but out of an abundance of caution we have issued a boil water advisory per protocol."
Boil-water advisories are typically put in place for at least 24 hours.
The airport confirmed the advisory had been lifted Friday afternoon and said the airport had returned to normal operations.
