Water Quality Advisory Issued for Crandon Park in Miami-Dade County

The Florida Department of Health in Miami-Dade County (DOH-Miami-Dade) issued a water quality health advisory on August 31, 2026, for Crandon Beach. According to health officials, routine water sampling at the site revealed bacteria levels that exceed safe standards for recreational use.

The advisory affects visitors planning to swim or participate in water-based activities along the popular shoreline. Officials use enterococcus bacteria testing to monitor marine water quality. High concentrations of these bacteria typically indicate fecal contamination from stormwater runoff, wildlife, or human activity, which can increase the risk of illness for swimmers.

Public Health Recommendations and Testing Status

State and local health authorities advise the public against swimming or engaging in water sports at Crandon Beach until further notice. Water contact in affected areas can lead to gastrointestinal illness, skin rashes, or infections if water enters the eyes, nose, or open wounds.

According to the Florida Department of Health, water samples will continue to be collected and tested regularly. The advisory will remain in effect until subsequent laboratory results confirm that bacteria levels have returned to acceptable federal and state recreational water quality standards.
