The pH value and electrical conductivity were monitored through the eight sampling campaigns. The pH values during each sampling campaign were low for the acid mine drainage, metallurgical wastewater, and water from the Bor River and Bela River. The pH values for the rivers without the impact of mining and metallurgical activities had the neutral values. Electrical conductivity for metallurgical wastewater had a value higher than the maximum value of the instrument.
