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]).作为佛罗里达州环境保护部（Department of Environmental Protection, DEP）流域管理举措的组成部分，该州所有流域每两年将依据《受损水域规则》（佛罗里达行政法典第62-303章）开展一次评估。本数据集覆盖范围整合了2022-2024年两年期评估（Biennial Assessment 2022-2024, BA，即第6周期）的全部内容，涵盖所有未达水质标准的水体识别码（Waterbody Identification, WBID）与参数组合（评估类别4a、4b、4d、4e及5）。本图层包含纳入《已核实受损水域清单》且被归类为评估类别5的水体及对应参数；属于《研究清单》的水体则对应评估类别4d或4e；纳入《合理保障计划》的水体对应评估类别4b；而那些总最大日负荷量（Total Maximum Daily Load, TMDL）已被纳入《佛罗里达行政法典》第62-304章且被归类为评估类别4a的水体亦包含在内。若某一水体识别码（WBID，即水体）对应多项未达标的参数，将生成重叠多边形以分别表征各参数。如需了解未达标水域的更多信息或有相关疑问，请联系凯文·奥唐奈（[e-mail]）；若有针对本图层的具体疑问，请联系菲尔·霍曼（[e-mail]）。
