Further information: 

The Australian Drinking Water Guidelines (ADWG) are designed to provide an authoritative reference to the Australian community and the water supply industry on what defines safe, good quality water, how it can be achieved and how it can be assured. The guidelines have been developed after consideration of the best available scientific evidence and provide a framework for good management of drinking water supplies to ensure safety at point of use. They address both the health and aesthetic quality aspects of supplying good quality drinking water.

The 2011 ADWG have been developed by the National Health and Medical Research Council (NHMRC) and undergo rolling revision to ensure they represent the latest scientific evidence on good quality drinking water. As sections of the Guidelines continue to be reviewed, the Table of Updates will be updated to provide the latest information.

Please refer to the NHMRC Public Consultation website for current invitations to make submissions relating to draft amendments of the ADWG, or for information about submissions made in previous public consultations.
