Florida Department of Environmental Protection Water Quality Guidelines
The Florida Department of Environmental Protection provides standards (PDF) for the amounts of some substances that can be discharged into Florida waters. They further reinforce a “designated use” approach by adopting surface water quality standards as follows:
- Class I waters are for potable water supplies.
- Class II waters are for shellfish propagation or harvesting and generally apply to coastal waters where shellfish harvesting occurs.
- Class III waters are based on recreation, propagation and maintenance of a healthy, well-balanced population of fish and wildlife. Note: The surface waters of the state are Class III unless described in rule 62-302.400 F.A.C. (PDF)
- Class IV waters for agricultural water supplies and are generally located in agriculture areas around Lake Okeechobee.
- Class V waters are evaluated for Navigation, Utility and Industrial Use. Currently, there are not any designated Class V bodies of water.
