Acid Rock Drainage

Laboratory acid rock drainage (ARD) prediction tests are used to determine the most appropriate disposal options for waste rock and tailings in order to minimize environmental impact. Maxxam offers the full range of ARD testing services for prediction studies and routinely conducts geochemical analysis, static testing and kinetic test programs.

To better approximate site conditions, larger scale tests under specific environmental conditions can be conducted. To simulate underwater disposal of water materials, custom subaqueous disposal (SAD) tests can be conducted (to predict pore water quality, seepage quality to groundwater, and surface water quality).

All test methods are offered including MEND, EPA, ASTM and NAG methods. Custom tests include a variety of sequential leach tests. Our extensive laboratory facilities enable customized experimental design and testing over a wide range of simulated environmental conditions.
