ADWG are the respected Australian reference for safe, good quality drinking water developed from the most up to date Australian and WHO scientific evidence.
Are concerned with the safety and aesthetic quality of drinking water for consumers. Because water is such a good solvent, pure water containing nothing else is almost impossible to attain. What is required is that dinking water be safe to people in most stages of normal life, including children over six months of age and the very old. It should contain no harmful concentrations of chemicals of pathogenic microorganisms, and ideally it should be aesthetically pleasing in regard to appearance, taste and odour.
- The ADWG include two types of guideline value;
- a health related guideline value &
- an aesthetic guideline value
- the guideline concentration is based on a lifetime of consumption
- the guideline values relate to the quality of water at the point of use (e.g. kitchen or bathroom tap etc.)
- exceeding a guideline value should be a signal to investigate the cause and consider remedial action
- the guidelines apply irrespective of the source (Council supply, rainwater tanks, bores etc.)
