Technical Document: Acid Mine Drainage Prediction

Acid Mine Drainage Prediction compares acid rock drainage factors of waste rock piles and tailings impoundments. In examining this table, it is important to note that diffusion of oxygen into water is slow and, therefore, oxidation of iron sulfide is inhibited until the water level drops, which can occur periodically or seasonally in some cases.

Acid Mine Drainage - Earthworks

Acid mine drainage can have severe impacts on fish, animals and plants. Many impacted streams have a pH of 4 or lower — similar to battery acid. For example, acid and metals runoff from the Zortman Landusky mine in Montana has harmed biological life in a dozen streams in the Little Rocky Mountains.

EPA - What is Acid Mine Drainage

Acid Mine Drainage (AMD) is currently the main pollutant of surface water in the mid-Atlantic region. AMD is caused when water flows over or through sulfur-bearing materials forming solutions of net acidity. AMD comes mainly from abandoned coal mines and currently active mining. AMD degrades more than 4,500 stream miles
