• Water quality in Magela Creek upstream and downstream of Ranger: A summary of findings for the 1999-2000 wet season (PDF 185 KB)

About the report

The implementation of the new Commonwealth Environmental Requirements (ERs) for Ranger Uranium Mine in January 2000 provided for a change in the ‘philosophy of compliance’ by which the mining company meets environmental objectives to minimise and prevent impact from occurring outside the mine lease. A major part of this change focuses on water quality, particularly in Magela Creek on exit from the mine lease, and the need to be able to discern an unusual change or trend which might provide early warning of a potential problem or verify an impact.
