The overall effect is to render the water toxic to varying degrees. Ultimately, the water becomes neutralised by a combination of dilution and reaction with river sediment or various minerals in soils, but certain constituents have relatively high solubilities and remain in the water, particularly sulphate. Not all of South Africa''s mineral deposits are afflicted by acid production: diamond ...

Rivers and dams are rerouted to create exposed riverbeds for mining which has a detrimental effect on fish and wildlife that use rivers for sustenance. Openpit mines are eventually abandoned and fill up with stagnant water which becomes infested with mosquitos. These sites are ideal breeding areas for malaria and other deadly diseases.
