Jupiter, FL - Florida Department of Health Palm Beach County has issued a “No Swimming Advisory” for Dubois Park after bacterial levels in the water tested in the poor range.

The area affected is the small lagoon located just off the Jupiter Inlet in the park. The latest testing showed 120 colonies per 100 milliliters of marine water for enterococci placing it in the poor range.
The ocean beach tested in the good range. Resampling is being conducted and results affecting the advisory should be available Thursday, January 1. Causes of the elevated level are unknown but are generally associated with wildlife, heavy recreational usage, or runoff following rains.

Health department staff samples the beach waters at 13 locations from Boca Raton to Jupiter for enterococci as recommended by the Florida Department of Environmental Protection and the EPA. The samples are laboratory tested for concentrations and a value assigned to indicate poor, moderate or good ranges.

The advisory will continue until samples collected are in the good range.
