As a result of Wednesday’s heavy rain and flash flooding, bacteria levels in a portion of the surf at Folly Beach have risen, according to the S.C. Department of Health and Environmental Control.

DHEC on Thursday announced a swimming advisory for a section of Folly Beach.

"The affected area includes 200 feet above and below the beach access at 5th Avenue East," said Harvey Wilkins of DHEC’s Region 7 Environmental Quality Control office. "High bacteria levels have been detected in this section of the beach, and swimming is not advised until bacteria levels return to normal."

An advisory means that DHEC advises people to not swim in the area, especially young children, the elderly, and those with compromised immune systems.

Advisories do not mean that the beach is closed. Wading, fishing, and shell collecting do not pose a risk, according to DHEC.
