Through land use associated with mining, impacts on water can arise from a multitude of sources. To gain access to minerals, metal and nonmetal mines are dewatered using pumping wells, diversion techniques and nearhorizontal drainage passages. In mining operations water is mainly used to extract and process ore at the mine site.
