Acid Mine, Drainage. ,Acid Mine, Drainage (AMD) occurs when sulphides in rocks are exposed to air and water. Mining disturbs large quantities of rock containing sulphide minerals. These minerals react with water and oxygen to create sulphuric ,acid,. When the underground water reaches a certain acidity level, a naturally occurring type of bacteria thrive.

water treatments are modeled after wastewater treatment plants, which are machine intensive, chemical dependant, and require continuous operations and maintenance (O & M) staff. Traditional solid mine waste remediation tactics involve covering of piles and water diversion tactics which do not treat wastes but rather mitigate their impacts.
