Public Policy and the Environment: Acid Mine Drainage

The one I want to discuss is called acid mine drainage (AMD). The best regulation in place to prevent this sort of environmental degradation – and save taxpayers millions and billions of dollars in water treatment – is SMCRA (the Surface Mining and Reclamation Act of 1977).

What can be done to prevent or clean up acid mine

Water flowing through active or abandoned mine sites can become polluted by the material being mined[1]. By far the most common mine drainage problem is that of acid mine drainage (AMD). Sulfuric acid is produced when water interacts with sulfur-bearing materials in the presence of oxygen and common bacteria[1].

Acid Mine Drainage (AMD): causes, treatment and case

Acid Mine Drainage (AMD) is produced when sulfide-bearing material is exposed to oxygen and water. The production of AMD usually – but not exclusively – occurs in iron sulfide-aggregated rocks. Although this process occurs naturally, mining can promote AMD generation simply through increasing the quantity of sulfides exposed.
