The addition of fluoride to a drinking water supply is generally governed by the Australian Drinking Water Guidelines. [6] The Guidelines recommend a health-related guideline value (maximum concentration) of 1.5 mg/L for fluoride, which mirrors the World Health Organization Guidelines for Drinking Water Quality 2006.

Benzene levels are regulated in drinking water nationally and internationally, and in bottled water in the United States, but only informally in soft drinks. The benzene forms from decarboxylation of the preservative benzoic acid in the presence of ascorbic acid (vitamin C) and metal ions (iron and copper) that act as catalysts , especially ...
Australia now provides fluoridated water for 70% or more of the population in all states and territories. Many of Australia's drinking water supplies began fluoridation in the 1960s and 1970s. By 1984 almost 66% of the Australian population had access to fluoridated drinking water, represented by 850 towns and cities.

The source of the contamination has been attributed to "corrosion in the lead and iron pipes that distribute water to city residents". [58] In 2015, the lead concentration of drinking water in north-eastern Tasmania, Australia, reached a level over 50 times the prescribed national drinking water guidelines. The source of the contamination was ...
Haloacetic acids (HAAs) are a common undesirable by-product of water treatment by chlorination.Exposure to such disinfection by-products in drinking water, at high levels over many years, has been associated with a number of health outcomes by epidemiological studies.
