Plain English Summary

AI-GENERATED
Requires cooling tower owners to register, test, and report to the state.

Every cooling tower, domestic water holding tank, and supplemental disinfection system in Florida must be registered with the health department before it starts operating, and re-registered whenever ownership changes.

Starting in mid-2027, owners must test cooling towers for bacteria and Legionella on a strict monthly schedule and report the results to the state every 90 days, with results made public if levels spike.

A qualified inspector must check every tower at least every 90 days and certify each year that its safety plan is being followed, while only certified applicators may disinfect it.

Health department and county officials may enter any property to inspect a cooling tower, and owners who skip registration, testing, or inspection face civil and criminal penalties, with each day of noncompliance a separate offense.
