The properties of surface waters affected by coal mining.
FAFÍLKOVÁ, Veronika
I watched the chemical characteristics of wetlands and surface waters in the vicinity of Lake Medard. This lake is a residual hole (after brown coal mining activities) which is now being filled with water. It is situated in Sokolov cadastre. I used physical, chemical and biological characteristics of water to characterize the surface water. The values have been compared with indicators of other surface water ecosystems. They were compared with Eger river water and with water from the south Bohemian fishponds. Results of comparing showed that all parameters of observed waters are very different. Surveyed parameters of the average concentrations are several times higher or on the contrary lower at individual sites of interest. Sites of interest are characterized by high levels of dissolved substances in water. Particularly problematic are sulphate anion concentrations and concentrations of Na, Ca, Mg, Zn, Mn and Fe cations.
