Notes:
-
Data Collected from both a health and aesthetic point of view, and obtained between the 1st April and the 30th June, 2009. WHO standards refer to the levels of contaminants at the point of consumption whereas the levels tested above are at the treatment plant. many of the levels like Lead and Iron will increase as they move through the grid.
-
The above drinking water quality monitoring data is representative of a selection of the water quality samples collected from the Brisbane city council water distribution system over the nominated period.
-
The drinking water quality monitoring program complies with statutory requirements.
