This study surveyed physicochemical properties and bacterial community structure of water and sediments from an acid mine drainage (AMD) dam in South Africa. High-throughput sequence analysis revealed low diversity bacterial communities affiliated within 8 dominant phyla; Acidobacteria, Actinobacteria, Chloroflexi, Firmicutes, Nitrospirae, Proteobacteria, Saccharibacteria, and ca. TM6 ...
However, when mining ceased, the pumping stopped, and voids have been steadily filling with water ever since which is exposed to sulphide bearing minerals to form acid mine drainage. The situation reached crisis point when in 2010 acid mine drainage started decanting to surface on the West Rand and quickly polluted the Tweelopiespruit which ultimately feeds into the Hartbeespoort Dam.

What is Acid Mine Drainage Sources of Non-point Source Pollution Acid Mine Drainage (AMD) is currently the main pollutant of surface water in the mid-Atlantic region. AMD is caused when water flows over or through sulfur-bearing materials forming solutions of net acidity. AMD comes mainly from abandoned coal mines and currently active mining. AMD degrades more than 4,500 stream miles in …
