Health officials in Palm Beach County are urging residents to stay out of the water at a well-known local park after recent testing uncovered bacteria levels far beyond what is considered safe for swimming.
The Florida Department of Health in Palm Beach County confirmed the advisory applies to DuBois Park, located at 19075 DuBois Road in Jupiter. Samples collected on Monday, August 3, 2026, during a routine water quality check revealed that Enterococcus bacteria levels at the site had climbed well past the threshold set for safe recreational use.
Enterococcus is a type of bacteria commonly used to measure the presence of fecal contamination in water. When levels rise above accepted limits, health experts warn that swimmers face a significantly higher risk of illness, including skin infections, gastrointestinal issues, and other waterborne conditions.
According to the health department, the advisory will remain active until follow-up testing confirms that bacteria levels have dropped back within the safe range. In the meantime, officials are strongly discouraging anyone from swimming, wading, or engaging in any water contact activities at the affected area.
Health officials noted that this type of contamination can result from several factors, including heavy rainfall runoff, wildlife activity, or nearby stormwater drainage systems flowing into recreational waters. Because bacteria levels can fluctuate quickly depending on weather and tidal conditions, the department continues to monitor the site closely and will update the public once conditions improve.
Residents visiting DuBois Park during this period are advised to avoid direct contact with the water, keep pets away from the shoreline, and refrain from allowing children to play near the affected area until the advisory is officially lifted.
Local authorities are expected to conduct another round of testing in the coming days. Until then, signage may be posted at the park to alert visitors of the ongoing risk.
Anyone who has recently come into contact with the water and is experiencing symptoms such as skin irritation, fever, or stomach discomfort is encouraged to seek medical attention.
