Acid drainage 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 it could well be this industry’s most harmful legacy. Effectively dealing with acid drainage is a formidable challenge for which no global solutions currently exist.

The International Network for Acid Prevention (INAP) is an industry group created to help meet this challenge. INAP exists to fill the need for an international body which mobilizes acid drainage information and experience. The network was founded in 1998. Since then INAP has become a proactive, global leader in this field.
