It is possible that some residents were exposed to elevated fluoride levels in their drinking water between 9 a.m. and 12 p.m. on May 1 2009.
This was an isolated incident and the chance of any health side effects are remote.
Given the short period of exposure, any adverse health effects are unlikely and would be limited - at the most - to very mild gastroenteritis.
Symptoms would have occurred within 24 hours of consuming the water and would have resolved within about 24 hours.
Queensland Health is confident there will not be any long term health impacts resulting from this incident.
