The Global Acid Rock Drainage (GARD) Guide addresses the prediction, prevention, and management of drainage produced from sulfide mineral oxidation, often termed “acid rock drainage” (ARD), “acid mine drainage” or “acid and metalliferous drainage” (AMD), “mining influenced water” (MIW), “saline drainage” (SD), and “neutral mine drainage” (NMD). The GARD Guide is intended as a state-of-the-art summary of the leading practices and technology to assist mine operators and regulators in the management of ARD. The GARD Guide was prepared by INAP with input from experts from multiple countries to create a truly global guide that benefits the entire mining industry and is intended to address all commodities produced by mining. It is aimed at the scientist or engineer with a reasonable background in chemistry and the basics of engineering but with no specific knowledge of ARD. It is not a not a design document; design requires a high level of understanding and site-specific knowledge of a particular project or mine. The GARD Guide is a “living document” that is updated periodically to reflect the results of ongoing research and advancing knowledge of ARD management technologies.
