Managed Aquifer Recharge in Mining: A Review.

Managed aquifer recharge (MAR) has been gaining adoption within the mining industry for managing surplus water volumes and reducing the groundwater impacts of dewatering. This paper reviews MAR for mining and includes an inventory of 27 mines using or considering MAR for current or future operations. Most mines using MAR are in arid or semi-arid regions and are implementing it through infiltration basins or bore injection to manage surplus water, preserve aquifers for environmental or human benefit, or adhere to licensing that requires zero surface discharge.
