Acidification mining lakes

Geidel G, Caruccio FT (1984) A field evaluation of the selective placement of acidic material within the backfiU of a reclaimed coal mine. In Proceedings of the 1984 symposium on surface mining, sedimentology and reclamation, University of Kentucky, Lexington, KY, pp 127-131 Geller W, Klapper H, Schultze M (1998) Natural and anthropogenic sulfuric acidification of lakes. 

Pollution of lake water is caused by the inputs of polluted river water, grotmd water and acid water from metal mines. Pollution and acidification of lake water have been considerably investigated by the model analyses. pH and the changes in the water quality of lake water inputted by acid rainwater and acidified river water will be considered below. 

One problem related to AMD is the acidification of aquifers close to mining areas that will affect directly all biota living around it. In some lakes near excavation regions, for example, the pH can reach the value of 2 The oxidation of the mineral sulfides will also affect the soil quality, because it can induce the release of heavy metals (Hg, Cd, As, and others) previously immobilized.
