Acid Mine Drainage, South Africa. Last update: . Description of the conflict case. Acid mine drainage is waste water that collects in abandoned gold and uranium mines on the Witwatersrand which chemically interacts with acidic and radioactive chemicals. It is dangerous because if left unpumped it rises to the surface.
