Recreational Water Quality

The City of St. Petersburg strives to maintain safe water for our citizens and environmental health. A statewide testing program for enterococci has been recommended by the United States Environmental Protection Agency (EPA) as a saltwater quality indicator. According to studies conducted by the EPA, enterococci have a greater correlation with swimming-associated gastrointestinal illness in both marine and fresh waters than other bacterial indicator organisms and are less likely to "die off" in saltwater.

Recreational Water Quality Results 

Recreational water quality is sampled and tested by the City of St. Petersburg Environmental Compliance Division at select surface water locations. Testing is completed weekly on Wednesday and results are usually posted on Thursday. If the test indicates sub-par water quality, testing will be performed again the following day. Results of the second test will be posted on Friday. If the second test still indicates poor quality, an "Advisory" will be issued for the sampling site.

The map and reports below provide information about the quality of environmental health, ambient water quality monitoring, trends in water quality and monitoring programs for sanitary sewers, background conditions, beaches and recreational areas.
