Every week, we conduct rigorous testing to monitor the quality and safety of drinking water, to ensure that the supply of water to households and businesses is of the highest standard.

This drinking water quality monitoring program is designed according to the Australian Drinking Water Guidelines (ADWG) and complies with statutory requirements under the Water Supply (Safety and Reliability) Act 2008.

*ADWG = Australian Drinking Water Guidelines 2011.             

The ADWG 2011 have been developed by the National Health and Medical Research Council (NHMRC) in collaboration with the Natural Resource Management Ministerial Council (NRMMC). The ADWG incorporates the Framework for the Management of Drinking Water Quality and provides the Australian community and the water supply industry with guidance on what constitutes good quality drinking water.

Bacteriological quality

Bacteriological quality is assessed by monitoring the water for the organism Escherichia coli as an indicator of contamination. A drinking water scheme is considered bacteriologically safe to drink if no E. coli are found in 98 % of samples analysed.

Chemical parameters    

Queensland Urban Utilities reports yearly on a number of water quality parameters. The performance for chemical parameters with a health value is assessed as recommended by the ADWG.

Performance is deemed as satisfactory if the 95th percentile value is less than the ADWG health guideline value.

Performance for parameters with an aesthetic guideline value is assessed as recommended by the ADWG. Water is considered good quality if the mean value of an aesthetical parameter is measured at less than the recommended maximum criteria described in ADWG.

Notes:

  • Health-related water quality complies with the ADWG that the annual 95th percentile value is less than the recommended ADWG value.
  • Aesthetic water quality complies with the ADWG in that the annual 50th percentile value is less than the recommended ADWG value.
  • E.coli complies with the ADWG at least 98% of scheduled samples contain no E.coli.

* Due to a poor water body quality at the regular Water Treatment Plant uptake point, an alternative source water was in use at the time of testing. This alternative water body contained a large amount of algae, which increases the concentration of dissolved organic carbon in the water. Dissolved organic carbon reacting with chlorine will create trihalomethanes (THM). Due to the short duration of exposure, no adverse health effects are likely. Levels of THM returned to normal when the treatment plant returned to uptake from the regular source water, following improvement in quality.

Notes:

  • Health-related water quality complies with the ADWG that the annual 95th percentile value is less than the recommended ADWG value.
  • Aesthetic water quality complies with the ADWG in that the annual 50th percentile value is less than the recommended ADWG value.
  • E.coli complies with the ADWG at least 98% of scheduled samples contain no E.coli.
