A secure and safe supply of drinking water is fundamental to public health. The NSW Government has endorsed the Australian Drinking Water Guidelines 2011 (published by the National Health and Medical Research Council and the Natural Resource Management Ministerial Council). The guidelines provide a solid foundation for assessing drinking water quality, by specifying health-based and aesthetic criteria as well as the philosophy of a "multiple barrier approach" from catchment to tap, so to ensure safety of the water.
