Acid Rock Drainage Services
From Specialty Services
Acid rock drainage and metal leaching (ARD / ML) has become increasingly important with regards to waste material management. Acid rock drainage (ARD) occurs when sulphide rich material is exposed to air and water through construction of mines, roadways, etc. The material becomes oxidized resulting in the formation of acidic metal rich leachate that can eventual be drained into groundwater seeps or surface water run-off. Consequently, acid rock drainage and metal leaching is one of the most serious environmental concerns related to mining activity globally.
