Free Chlorine Burnout Scheduled June 1–21, 2026
As part of the St. Johns County Utility Department’s ongoing efforts to enhance water quality in the distribution system, the CR 214 Water Treatment Plant will temporarily switch to free chlorine disinfection beginning June 1 for approximately 21 days, or until the distribution system has been fully flushed.
This burnout process is part of routine maintenance for the distribution system and occurs every one to two years based on water quality data and operational guidelines established by the U.S. Environmental Protection Agency and the Florida Department of Environmental Protection.
This temporary change does not affect customers in Ponte Vedra, Eagle Creek, U.S. 1 North, Fruit Cove, Bartram Oaks, Hastings, the State Road 16 corridor, or the World Golf Village area.
Chlorine Burnout FAQs
Why is the County temporarily switching from chloramines to free chlorine?
This maintenance procedure is recommended by the U.S. Environmental Protection Agency and the Florida Department of Environmental Protection. After the flushing process is complete, the water treatment plant will return to using chloramines for disinfection. This process helps to:
- Remove biofilm and bacteria from distribution system pipes.
- Reduce the formation of nitrates and nitrites, a process known as nitrification.
- Address taste and odor concerns.
Is the water safe to drink and use during this process?
Yes, the water remains safe to drink and use as usual. However, customers may notice slight discoloration, cloudiness, or a chlorine odor. Despite these temporary changes, the water meets all safety standards. Customers who are sensitive to chlorine or chloramines should take standard precautions.
What changes might customers notice?
Customers may observe:
- Slight discoloration or cloudiness in the water.
- A mild chlorine odor or taste.
- Minor fluctuations in water pressure during flushing.
- Temporary discoloration caused by system flushing.
- Utility crews operating fire hydrants to flush the system.
Many customers may not notice any changes. Critical users, such as hospitals, dialysis centers, and businesses that rely on water for processing, as well as pet, aquatic, and pond-related businesses, should consult their water treatment professionals regarding internal procedures.
What should customers do if they notice discoloration or odor?
If discoloration or cloudiness occurs, run water through an outdoor spigot or bathtub faucet for several minutes until it clears. Using these outlets helps resolve the issue more quickly and reduces the likelihood of debris clogging faucet strainers.
