Drinking water quality data

Every week, Queensland Urban Utilities conducts 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 2004 (ADWG) and complies with statutory requirements under the Water Supply (Safety and Reliability) Act 2008.

The following drinking water quality data is representative of drinking water quality for each scheme between July 2010 and June 2011.

* 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 waterbody 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 2004 that the annual 95th percentile value is less than the recommended ADWG 2004 value.
Aesthetic water quality complies with the ADWG 2004 in that the annual 50th percentile value is less than the recommended ADWG 2004 value.
E.coli complies with the ADWG 2004 at least 98% of scheduled samples contain no E.coli.
