Evaluation of quality and the renewal of surface water in the area affected by surface coal mining.
 VLÁŠEK, Ondřej
The aim of the study was to evaluate the parameters of quality and renewal of surface water in the area affected by surface brown-coal mining. Selected streams were monitored on the Great pokrusnohorska dump, and streams unaffected by dumps. Values of pH, conductivity, alkalinity, oxygen saturation and temperature were measured, and quantitative and qualitative samples of macrozoobethos were taken too. The dump?s water are characterized by high concentrations of dissolved solids and alkalinity. Species diverzity of these waters is lower and is affected not only by chemical compositon of the water, but also by the character of the bottom substrate.
