The production of this Global Acid Rock Drainage Guide (GARD Guide) was initiated in 2007, culminating in the roll-out of Version 0 of the GARD Guide during the 8th International Conference on Acid Rock Drainage (ICARD) held from June 22-26, 2009 in Skellefteå, Sweden. Version 1 was issued during the 9th ICARD held from May 20-24, 2012 in Ottawa, Ontario, Canada. The revision was largely based on comments and feedback received from users. Version 1 included major upgrades of Chapters 4 through 7, as well as numerous changes throughout the document related to updates and corrections.


The GARD Guide was made possible through financial contributions from the International Network on Acid Production (INAP) and the Mining Association of Canada (MAC). The project was developed and initiated by INAP in partnership with the Global Alliance.

Several organizations and many individuals contributed to the development of this GARD Guide. Golder Associates Ltd assembled a team that developed this version of the GARD Guide with the assistance and contributions from INAP member companies and consultants. INAP would like to thank all that contributed to the Guide.
