I monitored the chemical parameters of surface waters in wetlands and watercourses in the vicinity of Lake Medard (newly filled residual pit after brown coal mining). The characteristics of surface waters were described by means of their physical, chemical and biological indicators. The values obtained were compared with normal surface waters in the Czech Republic. I also assessed water quality and determined eutrophication. The chemical composition was compared in space and time. The most important finding is the high variability of waters in a relatively small area. Another is that the examined surface waters do not usually exhibit the typical characteristics of acid mine waters. The locations of interest are characterized by high levels of dissolved solids in water. High concentrations of sulphates are the most problematic of the found anions. In the case of cations, the following dissolved metals had high concentrations: Na, Ca, Mg, Zn, Mn and Fe.
