PLEASE NOTE: the verified list is not a list of all waters that do not meet water quality standards - it only contains waters that are awaiting a TMDL. Please see the Waters Not Attaining Standards (WNAS) layer to see all waters that do not meet water quality standards. As part of DEP’s watershed management approach, all of the basins in Florida are assessed every two years. The "verified list" is the list of Florida's impaired waterbodies in need of a total maximum daily load (TMDL) and that fail to attain designated uses and/or meet the minimum criteria for surface waters established in the Surface Water Quality Standards (62-302, F.A.C.) and the Impaired Waters Rule (IWR, 62-303, F.A.C.). If a waterbody is assessed as impaired, a TMDL must be developed to determine the maximum amount of a pollutant that a waterbody can receive and remain healthy. Once a TMDL has been completed, the waterbody is removed from the verified list regardless of whether or not the waterbody meets standards. For more information or questions regarding the verified list and assessments, please contact Jessica Mostyn (Jessica.Mostyn@FloridaDEP.gov). For more information or questions regarding TMDLs please contact Kevin O'Donnell (Kevin.ODonnell@FloridaDEP.gov). Purpose: Coverage includes all the WBIDs (Waterbody IDs - RUN 64) that are currently included on the verified list for any parameter from Group 1, Cycle 1 through the 2022-24 Biennial Assessment (referenced as Cycle 6), excluding WBID/parameter combinations that have subsequently been delisted in a later cycle. If a WBID is listed for multiple parameters the coverage contains overlapping polygons for each parameter.
