Mining and Water Quality

Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. Problems that can be associated with mine drainage include contaminated drinking water, disrupted growth and reproduction of aquatic plants and animals, and the corroding effects of the acid on parts of infrastructures such as bridges.

Polluted runoff from coal mines presents risk to water

'Acid mine drainage' from surface coal mines is a well-studied phenomenon in which run-off from coal mines have high concentrations of acid and heavy metals. This happens when exposed rocks containing pyrite, an iron sulphide, reacts with air and water to form sulphuric acid and dissolved iron – and the acid runoff can dissolve heavy metals such as copper into the water.

Drainage from underground coal mines, surface mines, and coal refuse piles is the oldest and most chronic industrial pollution problem in the Appalachian Coal Region. In 1995, 2425 miles (3902 km) of stream in Pennsylvania did not meet EPA-mandated in-stream water quality standards due to over a century of mineral extraction (PA DEP, 1996).

Water pollution is controlled by carefully separating the water runoff from undisturbed areas from water which contains sediments or salt from mine workings. Clean runoff can be discharged into surrounding water courses, while other water is treated and can be reused, such as for dust suppression and in coal preparation plants.
