Alternative Strategies for the Management of Mine Impacted Waters
« All Publications

Mining companies are increasingly challenged with water treatment obligations that may endure in-perpetuity.

Due to these pressures, they are undergoing a transformation from providing conventional to innovative environmental management solutions; implemented during initial mine planning through source control and water management, to operational and post closure water treatment and reclamation. Passive water treatment technologies that manage and treat mine-impacted water through stimulation of biogeochemical processes support this transformation, and may minimize compliance issues and operational requirements, and assist in meeting sustainability goals.

This presentation will exhibit Geosyntec's unique experience in developing, designing and implementing passive and semi-passive technologies for treatment of mine impacted water. Applications of technologies including Gravel Bed Reactors™ and bioreactors, constructed and engineered wetlands, and pit lake in-pit treatment will be presented as case studies. The deployment of mobile treatment systems to mine sites, such as containerized columns and "wetlands on wheels", will be discussed as an important stage to facilitate treatability studies, regulatory approval, and advancement of technology application to full-scale.

Each technology will be discussed as a function of its implementability from a perspective of site-specific conditions, effectiveness and expected impact on the local environment. Furthermore, treatment system configurations, treatment mechanisms, and seasonality will be explored to highlight the flexibility of their application in northern and remote sites.
