International Network for Acid Prevention

Acid Drainage

Acid and Metalliferous Drainage (AMD) is one of the most serious and potentially enduring environmental problems for the mining industry. Left unchecked, it can result in such long-term water quality impacts that could well be this industry’s most harmful legacy. Effectively dealing with AMD is a formidable challenge as indicated by the high liability cost carried by many mining companies.

It should be noted that AMD is also known as Acid Mine Drainage or Metal Leaching and Acid Rock Drainage (ML/ARD). It encompasses contaminant mobility under acidic or neutral/alkaline pH conditions.
