Acid mine drainage (AMD) and its effect on surface and groundwater resources in the Cradle of Humankind (COH) area near Krugersdorp is a pertinent and well-documented concern. In 2008, a water resources monitoring programme for the area was initiated and this contributed immensely to a better understanding of the AMD problem; for example, Figure 1 shows the inferred AMD footprint in the COH [1]. The Zwartkrans Compartment, which includes the Sterkfontein and Kromdraai sites, are characterised by high sulphate levels of more than 1000 mg SO4/L in places. The complexity of the karst environment and the availability of a limited number of monitoring boreholes have contributed to the need to improve the lateral delineation of the contamination footprint.
