Wastewater, containing toxic as well as valuable metals is discharged as ,acid mine, drainage (AMD) in major mining and industrial operations. This has led to a sharp increase in metal contamination of water reserves and a potential risk of decant water from closed mines is looming in the Western, Central, and Eastern basins of the Witwatersrand, South Africa.
