Abstract The article presents the results of hydrochemical studies of northern rivers of the Arctic zone of the Republic of Sakha (Yakutia). It was revealed that the background hydrochemical composition of surface waters in the study area is diverse: from hydrocarbonate-sodium waters in the North-West and hydrocarbonate-sulphate waters in the North-East of Yakutia. During the study of the microelement composition of surface waters in the Arctic zone, high concentrations of total iron, manganese, and copper are found everywhere, indicating their natural origin. In places where groundwater influence is observed we found that the characteristic elements are lithium, strontium and barium. Analysing the research results, we can say that each mining enterprise has its own specific effect on surface waters, which makes its own adjustments to the chemical composition of surface waters.
