communities, the mine may exist under a layer of limestone as in Latrobe at Monastery Run. This limestone layer, calcium carbonate, helps to neutralize the acid produced and the mine water discharge has a neutral pH and a considerable amount of alkalinity. When a discharge is alkaline, the treatment system is considerably easier and less costly.
Calcium carbonate, or CaCO3, comprises more than 4% of the earth''s crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years.
Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.
