Mining can change the quantity of surface and underground water and affect its quality. Acid mine drainage (AMD) or acid rock drainage (ARD) can be generated by discard dumps including those rehabilitated. The outflow of acidic water can happen 5 to 20 years after closure (Munnik, Hochmann et al. 2010).
