TYBEE ISLAND, Ga. (WSAV) – Health officials have lifted a water advisory for Tybee Island’s South Beach at Chatham Street.

On Tuesday, the Chatham County Health Department issued a notice for 18th Street to Inlet Avenue recommending swimmers stay out of the water.

Routine testing had detected enterococcus bacteria that could pose a risk of illness to those who come into contact with it.

The department on Thursday announced subsequent water samples showed the bacteria levels had dropped below Environmental Protection Agency’s recommended limits.

Periodic advisories are not unusual for Tybee Island and can be found listed on the Coastal Health District’s website. According to that page, there are three beaches within the district under permanent advisories, including King’s Ferry County Park at the Chatham/Bryan County line.

When such advisories are issued, the beach remains open, but the department warns against swimming or wading in the area. If fish or seafood is caught in the waters there, it should be thoroughly washed and cooked before eating.

Officials say sources of the bacteria could include animal waste, stormwater runoff or boating waste.
