Source Information

Water quality results displayed at this location were collected by the City of St. Petersburg Environmental Compliance Division. Weekly testing is conducted 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. City of St. Petersburg tests for levels of enterococci, a type of bacteria that indicates that pathogenic bacteria and viruses associated with fecal pollution may be present. These bacteria are known as fecal indicator bacteria (FIB). Florida Administrative Code, based on the US Environmental Protection Agency (EPA)’s 2012 Recreational Water Quality Criteria have the following rating criteria: Good= 0-35 CFU/MPN enterococci / 100 mL of marine water; Moderate= 36-70 CFU/MPN enterococci / 100 mL of marine water; and Poor= 71 CFU/MPN or greater enterococci / 100 mL of marine water. Swim Guide uses the thresholds for water quality based on the Florida Administrative Code. A beach is marked green (pass) when the sample results are equal or below 70 Enterococci / 100 ML water. A beach is marked red(fail) when the sample results are above 70 Enterococci / 100 ML water, according to EPA water quality guidelines. Data more than a week old will revert to “historical status”; clicking the pie chart icon will reveal a summary of the prior yearly or monthly pass/fail data. A sampling location is marked grey when no current or reliable monitoring information is available.
