Source Information
Through its Beach Monitoring Program, the South Carolina Department of Health and Environmental Control (DHEC) monitors the level of enterococcus bacteria at 122 sites along South Carolina’s coast. Testing is conducted during the beach season from May 15th to October 15th. Monitoring levels of enterococcus bacteria is the best way to determine whether disease-causing pathogens may be present in ocean water. DHEC monitors 27 sites at our local beaches (Isle of Palms, Sullivan’s Island, Folly Beach, Kiawah, and Seabrook). Monitoring sites are located near public access points to ensure the public’s safety. DHEC monitors our local beaches twice a month. When sample results are published on the Program’s website, Charleston Waterkeeper updates Swim Guide. A “Green” site = test result of 103 MPN/100 mL or lower OR a test result between 104 and 500 MPN/100 mL followed by a test result the next day of LESS than 104 MPN/100 mL A “Red” site = a test result of 500 MPN/100 mL or higher OR a test result between 104 and 500 MPN/100 mL followed by a test result the next day of 104 MPN/100 mL or GREATER A “Gray” site = no test result
