Abstract
The objective of this volume is to provide an account of the groundwater sampling and analysis program undertaken at Koongarra, as part of the Alligator Rivers Analogue Project. Chemical parameters were investigated in groundwaters at various locations and depths in the vicinity of the Koongarra orebody. Measurements of the pH, redox state, conductivity, and bicarbonate alkalinity provided a starting point for interpreting water chemistry. Groundwater samples were obtained using submersible pumps, or, in a few cases, bailers. The concentrations of major cations and anions, such as magnesium and phosphate, were determined using a variety of standard techniques. Numerous elements were routinely analysed using quantitative or semi-quantitative ICPMS. Uranium series radionuclides and environmental isotopes were measured using radiochemical techniques and mass spectrometry. The distributions of isotopes such as deuterium, tritium, 210Pb, 13C and 14C enabled groundwater mixing and flow-paths to be studied. The occurrence and distributions of major species at Koongarra are presented in this volume, using both cross-sections and contour plans. Chemical and isotopic data for groundwater analyses carried out during the project are included in the Appendices. 47 refs., 16 tabs., 58 figs
