    Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water. As water takes on harmful concentrations of minerals and heavy metals, it becomes a contaminant. This contaminated water can pollute the region surrounding the mine and beyond (Miranda, Blanco-Uribe Q., Hernandez, Ochoa G., Yerena, 1998).
