The objective of the GARD Guide is to collate and facilitate worldwide leading practice in ARD management. The GARD Guide currently has 11 chapters organized as a road map through the process of evaluating, planning, designing, and management of ARD over the life cycle of mining. The GARD Guide has also been prepared as a compendium of the concepts, techniques, and processes to be considered in successful ARD management over the mine-life cycle. It provides a broad, but not highly detailed, understanding of ARD technologies and management.

The GARD Guide focuses on mining and pertains to ores, wastes (overburden, waste rock, and residues/tailings), and mine workings (including in situ mining). The GARD Guide applies to the entire mining industry and all commodities produced by mining, and is applicable to the complete mine life cycle and to existing and historical ARD issues as well as future mining operations.

There is a considerable body of knowledge on ARD management in the scientific and engineering literature. The GARD Guide summarizes and references these, and it refers the reader to available, more specialized state-of-the-art guides.
