Water quality
Official status: Florida Healthy Beaches (Florida Department of Health) · Florida Department of Health in Duval County
The state samples beach water for enterococci bacteria: Good 0–35, Moderate 36–70, Poor 71 or more per 100 mL. If a result is above 70 and a resample is too, the county issues an advisory for that site. We haven’t found an official machine-readable feed we’re allowed to reuse, so we link to the official results instead of showing a status.
