 Florida's waterbody classifications are defined as: 

 1 - Potable water supplies 

 2 - Shellfish propagation or harvesting

 3F - Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in fresh water

 3M - Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in marine water

 4 - Agricultural water supplies

 5 - Navigation, utility, and industrial use

identified as impaired under the IWR, a priority of “medium” was assigned. Exceptions are waters where the impairment poses a threat to potable water or human health, which have been assigned a “high” priority, 

and fecal coliform impairments, which have been assigned a “low” priority. All other listings as of this cycle are prioritized based on the following: it is the Department's intent that listings with a "High" priority be 

addressed within the next 5 years, listings with a "Medium" priority be addressed within 5-10 years as resources allow, and listings with a "Low" priority be addressed within the next 10 years.

 PP - Planning Period (January, 1995 through December, 2004); VP - Verified Period (January, 2000 through June 30, 2007); X/Y (X = Number of exceedances of criterion and Y = number of samples)

Beach advisory data is based on "2006 Beach Advisories" file created 04/16/2007.

Fish advisory data is based on "2007 Fish Advisories" file created 07/11/2006 and updated 11/05/2007.

*A state wide TMDL for Mercury, that will address these waterbodies, is scheduled to be completed in 2012.
