Millicent (South Australia) – Fluoride

Highest Fluoride Levels recorded by SA Water 2000-12: Millicent 9/3/04 1.5mg/L.

Fluoride: ADWG Guideline: non-fluoridated water 1.5 milligrams per litre of drinking water
Fluoridated water 1.0 milligrams per litre of drinking water (rolling annual average). In Victoria, the Health (Fluoridation) Act 1973 states that the annual average for fluoride in drinking water shall not exceed a level of 1mg/L. It can be added to water supplies through the ‘Flurodose’ process. Fluoride is added to water either as fluosilicic acid (sometimes known as hydrofluosilicic acid) or sodium silicofluoride. It is sourced from superphosphate and is soluble.
Naturally occurring fluoride is almost insoluble and is known as calcium fluoride.
