Water Quality

MIWB has a comprehensive water quality monitoring program, which includes, amongst others, monitoring of the following common parameters:

  • PH
  • Temperature
  • Dissolved Oxygen
  • Electrical Conductivity
  • Colour
  • Turbidity
  • Metals
  • Heavy Metals
  • Escherichia Coli
  • Blue-Green Algae
  • Chlorine

Water is tested at various locations within Lake Moondarra and Lake Julius to determine the raw and recreational water quality. Testing ot water quality also occurs at various locations within the Mount Isa Water Boards water transmission and distribution networks and following the various treatment stages.

The results are compared to the Australian Drinking Water Guidelines (ADWG) for treated water and the Australian and New Zealand Environment and Conservation Council Guidelines (ANZECC) for raw water.

Water is monitored on a continuous, daily and weekly basis depending upon the parameter, its importance within the water treatment system and time of year. For instance, chlorine is monitored continuously at the main water treatment plant distribution points, while blue-green algae is tested weekly.
