Waters Not Attaining Standards (WNAS)

As part of DEP’s watershed management approach, all of the basins in Florida are assessed every two years under the Impaired Waters Rule (Chapter 62-303, Florida Administrative Code). This coverage is a compilation of the Biennial Assessment 2022-2024 (BA) (referenced as Cycle 6) and includes any WBID/parameter combination that did not attain standards (assessment categories 4a, 4b, 4d, 4e, & 5). This layer includes waterbodies and parameters that are on the Verified List of Impaired Waters and are identified as assessment category 5, those that are on the Study List are identified as assessment category 4d or 4e, those that are part of a Reasonable Assurance Plan are identified as assessment category 4b, and those with a DEP total maximum daily load adopted into Chapter 62-304, F.A.C. that are identified as assessment category 4a. If a WBID (waterbody) does not attain standards for multiple parameters, overlapping polygons are created to represent each parameter. For more information or questions regarding the waters not attaining standards, please contact Kevin O'Donnell ([e-mail]) or for questions specific to this layer, please contact Phil Homann ([e-mail]).
