(3) The supply of drinking water in the ACT is defined as a 'Licensable Public Health Risk Activity"under the Public Health Act 1997, and as such is licensed under that Act. Under the terms of the licence ACTEW must comply with the Drinking Water Quality Code of Practice 2000. This Code of Practice covers such things as testing frequencies, water quality testing, publication of results etc.

The technical requirements for water quality testing are referenced from the most recent Australian Drinking Water Guidelines (ADWG) as published by the National Health and Medical Research Council (NHMRC) and the Agriculture and Resource Management Council of Australia and New Zealand (ARMCANZ)

The drinking water monitoring program has therefore been designed to meet the requirements of these NHMRC Guidelines, plus whatever additional requirements are required by the Code of Practice. This is consistent with the approach adopted by most other water utilities throughout the country.
