Jupiter, FL - Florida Department of Health Palm Beach County has CANCELLED the “No Swimming Advisory” posted earlier this week for Dubois Park after recent sampling showed bacterial levels in the water to be in the good range.

The areas affected were Dubois Park’s small lagoon located just off the Jupiter Inlet which tested at less than 30 colonies per 100 milliliters of marine water.

Causes of the elevated level are unknown but are generally associated with wildlife, heavy recreational usage, or runoff following heavy 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.
