A swimming advisory issued Thursday for a section of Folly Beach was lifted Friday, the S.C. Department of Health and Environmental Control announced.

The area off 5th Avenue East, where unacceptable levels of bacteria were found by DHEC on Thursday, was reopened to swimming on Friday after tests found nothing unusual, Folly Beach City Administrator Toni W. Connor-Rooks said.

"Water samples indicate bacteria amounts in the affected area 200 feet on either side of the beach access at 5th Ave. East have returned to acceptable levels," Harvey Wilkins of the DHEC's Region 7 Environmental Quality Control office said Friday.

Wilkins cited heavy rains and flash flooding in the area on Wednesday as possibly contributing to the bacteria accumulation.

The area was closed to swimming Thursday, but caused no problems for residents or visitors, Connor-Rooks said.

She said Folly public works officials found a dead pelican and removed it from the area for which the advisory had been issued. It's not known if the dead bird was the source of the unusual bacteria level DHEC found, but she noted bacteria levels are again at acceptable levels.

Connor-Rooks said that in the past 30 years, unacceptable bacteria levels have been found only twice at Folly Beach.
