SULLIVAN’S ISLAND — Shellfish harvesting has been closed temporarily in the Intracoastal Waterway behind this barrier island.

The grounds from Ben Sawyer Bridge headed northeast to Conch Creek were closed because of a sewage spill of more than 100,000 gallons at the Sullivan’s Island Wastewater Treatment Plant, S.C. Department of Health and Environmental Control said this evening.

“This area includes all of State Shellfish Ground S217. The closure is only temporary and is the result of elevated bacteria levels associated with the spill. The affected areas will reopen once water quality data indicate the bacteria levels are acceptable for shellfish harvesting,” said Mike Pearson, DHEC shellfish sanitation section manager.
