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 are the contamination surface drinking water source or penetration into the local aquifer, but acid mine drainage also has effects on humans.
