  • OVERVIEWAkin to Ozone depletion and Global Warming, Acid Mine Drainage is a mammoth dilemma.South Africa is being faced with a water security quandary and AMD is currently one of the main pollutantsof surface water. Due to the fact that mining being the corner stone of the South African economy theissue of AMD has to be managed e ectively and with haste before this colossal crisis causes extremeecological degradation.Sulphur-bearing minerals exposed to the elements forms this metal rich water which contains toxicsubstances like arsenic, cadmium, lead and mercury and in certain instances it may even contain radioactiveparticles from uranium. AMD not only contaminates drinking water which is detrimental to humans buthinders the growth of aquatic plants and animals. It also has a corroding e ect on infrastructure. A strategicapproach needs to be implemented in order to successfully mitigate the damaging impacts of AMD.Attend this vital conference and gain insight into the causes, treatment, control and prevention of AMD.
