Groundwater resources near mining sites are at risk of contamination from the leaching of hazardous materials associated with mining. When used to line tailings ponds, waste storage areas, and leach pads, geomembranes isolate hazardous materials such as heavy metals, acids, and other pollutants. This isolation prevents the hazardous materials from migrating into the soil or groundwater.
Geomembranes help manage and control the flow of process water and leachate, directing them to treatment facilities rather than allowing them to disperse unchecked. This provides a barrier against pollution and protects groundwater resources. This prevents harm that could be caused both to the environment and public health from the adverse effects of mining activities.
