Gerhardminnebron is a natural karst spring located a few kilometers east of Ventersdorp in South Africa and draining into the Wonderfonteinspruit and Mooi River, which in turn flows into the Vaal River. It yields some 60 000 – 80 000 cubic meters of water per day, and is affected by exploitation and pollution by the gold mining industry in the region, deep–level gold mining having markedly impacted on the dolomitic aquifers. This spring is located in dolomitic rock that is part of the larger Boskop–Turffontein dolomite compartment in the Transvaal Basin. Dolomite is a sedimentary carbonate rock, a swath of which runs parallel to the Magaliesberg, and has a tendency to form large underground lakes and reservoirs.
