Revised Verified and Delist Lists of Impaired Waters for the Group 1 Basins

REVISED Verified and Delist Lists of Impaired Waters for the Group 1 Basins

The Department announces the availability of the REVISED lists of impaired waters for the Group 1 Basins: Everglades West Coast, Lake Okeechobee, Ocklawaha, Ochlockonee - St. Marks, Suwannee, and Tampa Bay.

These REVISED lists were produced with water quality and biological data included in IWR Database Run 56 and reflect several major milestones to the assessment of Florida’s waterbodies.  In particular, the REVISED lists include the revised dissolved oxygen criterion assessed as percent saturation (replacing the assessment of dissolved oxygen as mg/L) and the implementation of numeric nutrient criteria for streams, lakes, springs, and estuaries.  These assessments incorporate water quality and biological data that has been received by the department as of November 30, 2018 and include information received on the draft assessment lists. 

These lists reflect the department’s current assessments for these waterbodies, but they are subject to change based on input received during the public comment period, which ends May 31st, 2019. During this period, we ask that interested parties submit their comments either electronically to Kevin O’Donnell or by mail to the address below.  In addition to the revised assessment lists, the department posted the Master Lists (which contains assessments for all waterbodies in each basin) here.

Waterbodies and water segments identified on the REVISED Verified Lists have been determined to not meet water quality standards and will be added to the State’s Verified List of Impaired Waters and the federal 303(d) list. Waterbodies and water segments identified on the REVISED Delist Lists include those waters that are proposed for removal from the State’s Verified List and federal 303(d) list for several reasons: the waterbody is no longer impaired, a TMDL has been completed, the parameter verified impaired in the previous assessment was due to a flaw in the original analysis, or changes have been made to the waterbody type or class.  

Following the adoption by the Secretary of the department, waterbodies identified on the REVISED Verified List will be scheduled for TMDL development. A TMDL represents the maximum amount of pollutant loading that can be assimilated by a waterbody and have it meet its designated uses.
