Water Quality Characteristics of Eight Billabongs in the Magela Creek Catchment

摘要

The billabongs downstream of the Ranger uranium deposits in the Alligator Rivers Region of the Northern Territory have been identified as being potentially endangered. The mining companies propose to discharge contaminated waters to Magela Creek at times of high flow with the possible subsequent problem of accumulation of contaminants such as radium, uranium and heavy metals in the billabongs. An understanding of the billabong ecosystems is needed if the Supervising Scientist is to be able to determine monitoring programs that will enable the detection of any deleterious environmental effects due to the mining operations. A survey of the physico-chemical limnology of the billabongs was conducted during a six-week period covering the end of the dry season to the commencement of the wet season.
