Abstract This paper presents the results of the monitoring of pH value and concentrations of the dissolved and particulate forms of copper in the period from 2015 to 2021 in wastewaters that form Bor River, and in the water of Bor River, Krivelj River, Bela River, and Timok River which are under the influence of mining and metallurgical activities in Bor. Copper was mainly present in dissolved form in acidic river water, whereas in neutral and alkaline river water, copper was present relatively equally in both dissolved and particulate form. According to the pH values and copper concentrations, the water quality of Bor River and Bela River did not improve during the studied period. On the other hand, the water quality of Krivelj River significantly improved, possibly due to the changes caused by the construction of the new flotation tailing pond “Veliki Krivelj Zero Field”. The quality of Bor River, Bela River, and TimokRiver was largely controlled by the temporal influxes of highly acidic and copper-rich wastewater from metallurgical facilities in Bor.
