Ongoing disruption to water fluoridation in Espanola’s municipal water supply

Fluoride concentrations in the Espanola water supply are currently below the therapeutic levels recommended due to ongoing technical challenges at the Espanola Water Treatment Plant. There are no immediate or short-term health risks to the public. Over the long-term, if fluoride levels are not kept at optimal levels, residents and especially children are at greater risk for tooth decay.

The optimization of fluoride levels in the water supply at the Town of Espanola’s water treatment plant had been on pause from May to September due to an equipment malfunction with the fluoride analyzer. Repairs to the system were completed in September, and fluoride levels had returned to normal. However, due to ongoing technical problems, residents are not currently receiving optimal amounts of fluoride through their drinking water.

In accordance with requirements of the Ontario Public Health Standards, Public Health Sudbury & Districts reviews drinking water quality reports for all municipal drinking water supplies with fluoride control, and informs 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 concentrations return to normal 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).
