Application Of Environmental Isotope Tools To Improve Conceptual And Numerical Modeling Of Groundwater Flow In Kosh Goldfields, Witwatersrand Basin, South Africa

Environmental isotope and hydrochemical analyses were employed to improve existing understanding of groundwater flow dynamics in the defunct mine for assessing the source of water at a pumping shaft located near Stilfontein Town, Northwest Province, South Africa. Currently pumping is done using the shaft at an average rate of 37,000 m3 /day to prevent flooding of downstream mines.
