Acid Mine/Rock Drainage

Acid mine drainage (AMD) is one of the major water quality issues in Colorado and at locations throughout the western US USGS and INSTAAR researchers are collaborating on a variety of AMD projects as well as investigations of naturally-occurring acid rock drainage (ARD)Objective Reduce or prevent acid mine drainage from coal refuse piles and surface mines by inhibiting the growth of acid- causing bacteria Approach A dilute surfactant or detergent solution is applied directly to coal refuse piles or overburden using a hydroseeder or road watering truck The surfactant treatment can be used either as a preventive measure to avoid a potential acid drainage.

Acid Mine Drainage

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal min , so water must be constantly pumped out of the mine in order to prevent flooding When a mine is abandoned, the pumping ceases, and water floods the 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].
