Alabama’s Department of Public Health issued Friday morning a public swimming advisory for Perdido Bay, Mobile Bay and the Fairhope Public Beach.

Due to recent poor water quality test results, swimming in the areas may lead to an increased risk of illness.

The ADPH said the affected areas were Perdido Bay at Kee Avenue, Spanish Cove in Lillian, Mobile Bay at Volanta Avenue, Orange Street Pier, and Fairhope Public Beach, according to reports.

The ADPH said they will continue monitoring the water quality and the advisory will be lifted once bacteria values fall below the Environmental Protection Agency’s threshold of 104 enterococcus organisms per 100 milliliters for marine water.

The ADPH says that bacterial concentrations in recreational waters can increase during and immediately following rainstorms due to overflowing sewage collection and treatment facilities, storm water run-off, malfunctioning septic systems and agricultural run-off.
