Since the 2001/2002 wet season, the Supervising Scientist Division has undertaken a formal water quality monitoring program to monitor and assess impacts upon ecosystems and humans arising from mining activities at Ranger and Jabiluka.
The water chemistry monitoring program is conducted in Gulungul Creek in the period of flow in order to
- enhance the baseline/background dataset for water chemistry upstream of Ranger, and
- detect potential mine-related changes in water quality and isolate their source.
The specific indicators to be measured include electrical conductivity (EC), turbidity, uranium, manganese, magnesium and sulfate.
Since 2001 the water chemistry monitoring program has evolved, through extensive research, from a program of weekly grab samples to the 2010 water chemistry monitoring program of continuously monitored physico-chemical parameters with fully automated water samplers.
Further details of the changes can be found at SSD wet season monitoring program 2010-11.
