Bacteria TMDLs

Draft TMDL Reports  | Upcoming Meetings

Bacteria TMDLs are developed for waterbodies that do not meet bacteriological quality criteria designed to protect human health, which are defined in the State’s Surface Water Quality Standards (Chapter 62-302, F.A.C.). The Department of Environmental Protection (DEP) uses the best available information to identify waterbodies and water segments that do not meet the applicable water quality standards, including fecal indicator bacteria (FIB), following the methods in the Impaired Waters Rule (Chapter 62-303, F.A.C.) The comprehensive list of waters not attaining standards is available through the DEP’s Watershed Assessment Section webpage. The Bacteria TMDLs described below have been established to address FIB impairments in fresh and marine waters throughout the state, that do not meet the applicable criteria for Escherichia coli (E. coli), enterococci, or fecal coliform bacteria.

News and Announcements 

New! The department announces a public meeting to present and receive public comments on the revised draft fecal indicator bacteria Total Maximum Daily Loads (TMDLs) for impaired surface waters in the Everglades West Coast Basin, to be adopted in Rule 62-304.810, F.A.C. The meeting is scheduled for October 14, 2025, 2 p.m. to be held virtually via GoToWebinar. Registration for the webinar is provided below under meeting location.

The revised draft TMDL document and supporting data files for these impaired waters is available below, and will be provided upon request to interested parties by mail or via email distribution. The Everglades West Coast Basin TMDLs serve as a pilot for documenting bacteria TMDLs throughout the state in reports using a basin or other regional approach. The department will accept written comments on the draft TMDLs, as well as the establishment of these bacteria TMDLs based on the generally applicable criteria in subsection 62-302.530(6), F.A.C., through October 31, 2025.

Written comments should be directed to: Eric.Simpson@FloridaDEP.gov, Mail Station #3555, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400.
