When mine operations stop, dewatering pumps may be turned off and water levels start to return to their natural level, this process is known as “rebound”. The water comes into contact with rock that contains sulphide minerals that have been exposed through mining activities and the pH of the water may drop considerably due to the resulting chemical reactions. This acidic water could dissolve into other minerals in the rock, which can lead to high concentrations of pollutants such as lead, zinc, aluminium or cadmium in the water and high salinity generally.
