 Where a parameter was only 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.

1 Florida's water body classifications are defined as: 1 - Potable water supplies, 2 - Shellfish propagation or harvesting, 3F - Recreation, propagation, and maintenance of a healthily, well-balanced population of fish and wildlife in fresh 

water, 3M - Recreation, propagation, and maintenance of a healthily, well-balanced population of fish and wildlife in marine water, 4 - Agricultural water supplies, 5 - Navigation, utility, and industrial use.
