What Is The Environmental Impact Of The Mining Industry .

Apr 25, 2017 · Mining is the extraction of minerals and other geological materials of economic value from deposits on the earth. Mining has the potential to have severely adverse effects on the environment including loss of biodiversity, erosion, contamination of surface water, ground water, and soil. The formation of sinkholes is also possible.

Mining and Water Quality

The acid runoff further dissolves heavy metals such as copper, lead, mercury into groundwater or surface water. The rate and degree by which acid-mine drainage proceeds can be increased by the action of certain bacteria. Acidic, metal-laden drainage from abandoned coal mines can have substantial effects on aquatic resources.
