Supervising Scientist investigation into Ranger Uranium Mine tank failure

Department of the Environment

Media release
13 December 2013


The Supervising Scientist is currently undertaking an investigation into the recent incident involving the failure of a leach tank in the processing area of Ranger Uranium Mine.

The purpose of the Supervising Scientist’s investigation is to confirm that there has been no impact on human health or the off-site environment, including Kakadu National Park, as a result of the incident.

The outcomes of the Supervising Scientist’s investigation will be made publically available in due course.

The Supervising Scientist’s investigation is separate from, but complementary to, the investigation and review into the incident announced today by the Australian Government Minister for Industry, the Hon Ian Macfarlane MP and the Northern Territory Minister for Mines and Energy, the Hon Willem Van Holthe MLA.

These investigations will determine the cause of the tank failure and extent and nature of the impact of the spill, and provide assurance to stakeholders that the Alligator Rivers Region environment remains protected from the impacts of uranium mining.

Further detail on the role and responsibilities of the Supervising Scientist, including the latest results of continuous chemical and biological monitoring of the environment surrounding the mine lease, is available from the Supervising Scientist Division’s website at http://www.environment.gov.au/topics/science-and-research/supervising-scientist-division.
