Australian Drinking Water Guidelines: Draft amendments to Chapters Six and Eight

National Health and Medical Research Council 31 July 2015

Public Comments close on Monday, 31 August 2015, 05:00pm (AEST)

NHMRC is seeking public comment on draft amendments to Chapters Six and Eight 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:
Chapter Six – Physical and Chemical Qualities of Drinking Water
Additional text has been drafted for Chapter Six that provides information on the process for determining interim guideline values for chemicals that have been detected in drinking water but do not have a guideline value in the ADWG.
Chapter Eight – Water Treatment Chemicals

The proposed amendments serve to update the information about the approval process for new water treatment chemicals. NHMRC previously had a role in approving new water treatment chemicals. However, consideration of the safety and efficacy of new water treatment chemicals is the responsibility of jurisdictional health regulatory authorities. Chapter Eight has been updated accordingly.
