Water quality standards in and around mining areas are protected from contaminants by containing hazardous substances within impermeable liners which prevent leaching. When geomembranes are used to line containment facilities such as tailings ponds, waste storage areas, and heap leach pads, they effectively isolate hazardous substances, including heavy metals, acids, and other pollutants, from the soil and groundwater.
This containment ensures that any leachate or runoff generated from mining activities is contained and directed toward treatment facilities rather than being dispersed into the environment unchecked. By preventing the release of contaminants, geomembranes help ensure water quality, protecting aquatic ecosystems and complying with regulatory standards for water quality.
