Is Your Water Clean?

Tampa Bay Waterkeeper tests and reports the bacteria levels of your favorite waterways bi-week. We make it easy for you to access these results, the Department of Health’s (DOH's) Healthy Beaches testing results, and they City of St. Petersburg Environmental Compliance Division's testing results on our free app called Swim Guide.

EPA has set the following standards for water considered safe for swimming, which are used by DOH and Tampa Bay Waterkeeper:

0-70 CFU/MPN per 100 mL enterococci per sample: Safe for swimming

70+ CFU/MPN per 100 mL enterococci per sample: Not safe for swimming

How do I find the latest water quality results?

You can download the Swim Guide app, visit the website, or just keep scrolling. Swim Guide is a popular tool for water lovers in Florida.

The information contained on this website is for informational purposes only. All sites monitored are natural waterbodies and contaminants are present from a wide variety of sources! Local conditions fluctuate, sometimes dramatically, and especially after rainfall events. The results displayed above are only representative of the exact time, date and location at which the sample was taken and do not represent the water quality between sampling events or at other locations nearby. Users of these data should not assume that a “low” enterococci level means that it is necessarily safe or risk-free to make contact with the water. Enterococci is not the only contaminant of concern for recreational users and is used merely as an indicator of potential fecal contamination. Tampa Bay Waterkeeper, their directors, and agents can provide no guaranty of water safety and, as such, the user assumes all risks associated with the use of these data and swimming.
