Acid Mine Drainage
Acid Mine Drainage Definition
Acid Mine Drainage (AMD) is a natural phenomenon of a contaminated run-off formed by a chemical reaction between air, water and rocks containing sulfur-bearing minerals (Pyrite). The increased soil excavation of mining activity further accelerates AMD formation.
Acid Mine Drainage Effects on the Environment
Acid mine drainage is a problem because it is usually very acidic, and rich in sulfates, hardness and dissolved heavy metals. The main concerns of regarding acid mine drainage effects on the environment are the contamination of a surface drinking water source or penetration into the local aquifer, but acid mine drainage also has effects on humans.
