Abstract

The water of a mountain brook was analysed and selected water quality parameters were determined. The pristine mountain brook water contained the smallest numbers of microorganisms whereas in the polluted water body downstream, the values of chemical oxygen demand, biochemical oxygen demand after five days and the count of specific indicator organisms (faecal coliforms) were increased.

Keywords

biochemical oxygen demand values; chemical oxygen demand values; indicator microorganisms; water quality; water pollution
