About the report

Water release standards for the Magela and Coopers Creeks, downstream of the Ranger and Nabarlek uranium mines respectively, were set during the 1980s based on the recommendations of the Supervising Scientist. The age of these standards, the acquisition of long-term data sets for the area, improved analytical techniques and changed recommendations/guidelines by peak bodies (ie the World Health Organization and the Australian and New Zealand Environment and Conservation Council) mean that the original standards require reviewing. Therefore, the Supervising Scientist has committed to review the standards applied to waters downstream of the Ranger Uranium Mine prior to the 2003–04 wet season.

To facilitate a review of those standards the original unpublished working document, Water release standards in the Alligator Rivers Region: An Assessment by the Alligators Rivers Region Research Institute (circa 1984), containing the rationale and assumptions on which the recommendations were based is reproduced here, along with an extract from the Alligator Rivers Region Research Institute Annual Research Summary for 1984–85 which summarises the original document.
