International Network for Acid Prevention
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.
Our Mission
INAP drives leading practice in acid and metalliferous drainage risk management so that mining companies can operate sustainably in their respective environments across the asset lifecycle. This is achieved through industry-led collaboration, knowledge development and sharing.
Join INAP
INAP invites all companies concerned with risk management of sulfide mine waste and AMD mitigation to take an active role in the INAP network. Take advantage of our:
- Networking & Info-sharing
- Technology Transfer
- Gap-driven Research
Global AMD Resource
In 2009, INAP published the GARD Guide, a best practice guide for the prevention and mitigation of Acid Rock Drainage. Since that time, the GARD Guide has rapidly become recognized as the premier global guide on AMD. The GARD Guide is free for all to use and is found on the internet.
