Beach Water Quality from the Florida Healthy Beaches Program

Coastal beach water samples collected every two weeks by the county health departments are analyzed for enterococci and fecal coliform bacteria. High concentrations of these bacteria may indicate the presence of microorganisms that could cause diseases, infections, or rashes. County health departments will issue health advisories or warnings when these conditions are confirmed. Learn more about the Florida Healthy Beaches Program »

    Red Tide

    The gulf and bays of southwest Florida experience a "red tide" that is caused by recurring high concentrations of an alga that discolors the water and releases toxic chemicals. In Florida, under suitable conditions, the microscopic organism (Karenia brevis) successfully reproduces to more than a million cells per liter. The toxins kill fish, manatees, birds, and other wildlife, make shellfish inedible, and make beachgoers uncomfortable. The economic losses to the recreation industry can exceed tens of millions of dollars. Public outcry about persistent red tides has stimulated an increased resolve among researchers to understand the complex bloom mechanisms and to develop methods to alleviate the troublesome effects.

        Water Clarity

        Water clarity or turbidity measures the degree to which light is blocked because the water is cloudy or contains suspended particles, such as algae. Water clarity is one indicator of a waterbody's ability to sustain plants and wildlife. Learn more about water clarity »

          Bacteria

          The currently used bacterial indicators for recreational waters include total coliform, fecal coliform and enterococcus. Indicator organisms themselves are not necessarily pathogenic but their presence "indicates" or suggests recent contamination by human sewage or other waste which may result in human illness. Sources of contamination include storm water runoff, sewage overflows and feces from wild and domestic animals. Learn more about marine indicator bacteria »

              Salinity
              Salinity measures the amount of salts dissolved in water. An estuary can exhibit a change in salinity throughout its length as fresh water entering from the tributaries mixes with seawater from the ocean. Learn more about salinity »

              Water Quality Contour Maps

              Example Contour Map

              Contour mapping is one of the best ways to visualize spatial differences in coastal water quality, but the software and technical expertise needed to create them is unavailable to the general public and is out of reach even to many environmental resource managers and scientists. With original funding from an Environmental Protection Commission of Hillsborough County's Pollution Recovery Fund grant, the Water Atlas Program developed online tools to allow rapid map creation and comparison. Using these tools, anyone can view, download and print predefined maps that are automatically generated from selected data on a periodic basis. Optionally, users can create their own custom contour maps to display any data that is stored on the Water Atlas, by choosing a water quality parameter and date range that interests them.

              Available water quality parameters include:

              Chlorophyll a, Color, Dissolved Oxygen (Bottom), Dissolved Oxygen (Surface), Fecal Coliform, Salinity (Bottom), Salinity (Surface), Secchi Depth, Temperature, Total Nitrogen, Total Phosphorus, Turbidity

                Impaired Waters

                The Impaired Waters Data is the most recent available data from FDEP, but it may not reflect the current FDEP impaired list. These data are updated when and as soon as they are made available from FDEP.

                Impaired

                This waterbody is impaired according to the State of Florida's Impaired Waters Rule (IWR) Chapter 62-303 F.A.C. that governs the Total Maximum Daily Loads (TMDL) Program or according to the U.S. Environmental Protection Agency (EPA). Identification of Impaired Surface Waters (IWR) is a new scientific approach for guiding Florida Department of Environmental Protection process for identifying and prioritizing impaired surface waters in Florida. The rule evaluates whether waters meet their designated uses for a particular analyte, which include aquatic life use support, primary contact and recreation use support, fish and shellfish consumption use support, and drinking water use support. All water resources in this county are designated as Class III waters. Class III waters are considered recreational use waters, which means that the water should be fishable and swimmable. Class II waters are for shellfish propagation and harvesting. Class I waters are considered potable (drinkable) water supplies. As part of the terms of a court order related to the 1998 303(d) list of impaired waters, some waters are listed as impaired by EPA but not listed by the State of Florida.
