ADWG rolling revision - public consultation on HBTs open until 29 June

May 1, 2018

The Australian Drinking Water Guidelines (2011) is revised regularly to ensure it provides the latest scientific evidence on good quality drinking water. The National Health and Medical Research Council (NHMRC) is seeking public comment on a draft revised Chapter 5 on Microbial Quality of Drinking Water and accompanying technical appendix.

This draft incorporates a microbial Health Based Target (HBT) developed by the NHMRC Water Quality Advisory Committee (WQAC) using the WHO's Quantitative Microbial Risk Assessment (QMRA) framework. Treatment targets are based on source water category using the best available Australian evidence/data to determine the type and number of treatments required to meet the microbial HBT.

The purpose is to inform water utilities and regulators on the water treatment needed to reduce microbial risk to an acceptable level.

Consultation is open for 60 days until Friday 29 June 2018 5pm (AEST) and interested parties are invited to make a submission to NHMRC about the proposed changes.

The draft amendments and information on how to make a submission can be obtained from the NHMRC public consultation website

Issues raised during the public consultation process will be considered by the WQAC in finalising the chapter, which will then be published as part of the ADWG.
