Fluoride is added to water supplies to protect teeth against decay.

The Geelong region's water supply has been fluoridated since June 2009. Colac's water has been fluoridated since 2010. Other supply areas are not currently connected to a fluoridated supply.




Fluoride is added to reach an optimum dosage of 1 part per million (1 milligram per litre).

The National Health and Medical Research Council (NHMRC) has determined the safe concentration of fluoride in drinking water based on health considerations. This is published in the Australian Drinking Water Guidelines.

The addition of fluoride to drinking water supplies is carefully controlled and monitored.



Taste, smell and colour

The addition of fluoride doesn't change the taste, smell or colour of water.

Fluoride is a naturally occurring element in water, and the addition to drinking water supplies is not noticeable.
