The Australian Drinking Water Guidelines 2011 (ADWG) are part of the National Water Quality Management Strategy. The ADWG have been developed by the National Health and Medical Research Council (NHMRC) and are designed to provide an authoritative reference to the Australian community and the water supply industry on what defines safe, good quality drinking water, how it can be achieved and how it can be assured. The ADWG undergo rolling revision to ensure they represent the latest and best scientific evidence on good quality drinking water.
NHMRC is seeking public comment on draft amendments to Chapters Six and Ten of the ADWG. You are invited under paragraph 13(d) of the NHMRC Act 1992 to make a submission to NHMRC about the draft amendments. The draft amendments are as follows:
Guidance on rounding
This draft text is proposed to clarify how the guideline values are derived for chemicals in drinking water, and how monitoring results should be compared with guideline values.
Guidance on parent compounds and metabolites
Some chemicals (mainly pesticides) break down in the environment. Where the chemical likely to be present in water is an environmental breakdown product, it is appropriate for the Fact Sheet to be focused on the environmental breakdown product rather than the parent chemical.
The use of screening assays
This text has been developed at the recommendation of the WQAC, to clarify that screening techniques are legitimate analytical techniques for monitoring chemicals in drinking water, and details how the results should be interpreted.
