    Mining can have harmful effects on surrounding surface and groundwater. If proper precautions are not taken, unnaturally high concentrations of chemicals, such as arsenic, sulfuric acid, and mercuryover a significant area of surface or subsurface water. With large amounts of water used for mine drainage, mine cooling, aqueous extraction and other mining processes, increases the potential for these chemicals to contaminate ground and surface water. As mining produces cop
