Interruption to water fluoridation in Espanola’s municipal water supply

Due to an equipment malfunction with the fluoride analyzer, the optimization of fluoride levels in the water supply at the Town of Espanola’s water treatment plant has been on pause since the end of May. There are no immediate health risks to the public. Optimizing the levels of fluoride in drinking water systems is a safe and effective way to prevent tooth decay. The interruption to fluoridation means that residents who receive their water supply from the Espanola Water Treatment Plant are not receiving optimal amounts of fluoride through their drinking water.

In accordance with the requirements of the Ontario Public Health Standards, Public Health Sudbury & Districts reviews drinking water quality reports for all municipal drinking water supplies in which fluoride is added, and is required to inform affected residents when fluoride concentrations in their water supply fall outside the therapeutic levels (0.6–0.8 ppm) for more than 90 consecutive days.

Repairs to the system are underway and water fluoridation will resume once they are completed. Public Health Sudbury & Districts will continue to monitor the situation and update the public when the fluoride concentration returns to optimal levels in Espanola.

Affected residents can ensure that they continue to protect their dental health by brushing their teeth with fluoridated toothpaste. Residents at higher risk of tooth decay or who have any concerns about the impact of the reduced fluoride levels on their oral health, may wish to consult their family dentist regarding additional preventive measures. The use of additional products containing fluoride must be recommended by an oral health professional after an assessment of individual oral health and risk for tooth decay.

Children and seniors from households with low-income may qualify for preventive oral health services offered by Public Health Sudbury & Districts. For more information about these services, please call 705.522.9200, ext. 236 (toll-free 1.866.522.9200).
