    The process of strip mining also lowers groundwater levels around the mine. In order to remove the coal, vast quantities of groundwater are pumped out of the mine and as a result, surrounding ecosystems and farmland may become drier, and erosion may start to change the landscape. Strip mining also uses significant amount of water to suppress dust.
