Runoff from mining sites is managed by containing and controlling the flow of water via geomembrane liners which do not allow contaminants to leach from the container. Without containment, stormwater is free to run unabated across mining sites where they will pick up and carry off dangerous chemicals into the surrounding environment.
The use of geomembrane liners to contain this runoff means that the water will be contained within the designated area and directed toward treatment facilities rather than being dispersed into the environment unchecked. This protects aquatic habitats and complies with regulatory standards for environmental protection.
