ABSTRACT. The main sources of drinking and domestic water supply in the Chechen Republic are groundwater. The scares information on the intensity of pollution and the elemental composition of groundwater in the republic, as well as the heterogeneity of the distribution of chemical elements, largely associated with the presence of mountain areas, determines the necessity of detailed investigations. Water chemical and elemental composition of springs situated in the Valeric river valley at the Valeric settlement territory, Achkhoy-Martan district of the Chechen republic, is studied. All water samples were alkaline (pH 8.12–8.77), with relatively low levels of hardness (2.1–3.0 mg-eq/dm3) and mineralization (213–441 mg/dm³) and low fluorine content (0.28–0.36 mg/dm³). Among the studied indicators, risk factors are an increased content of nitrates (indicated concentration range reached 0.67–1.33 MPC). Water of springs situated at the river downstream contained significantly higher concentrations of all elements investigated. The highest coefficients of variations were revealed for B (84.6%), Cu (85.8%), Se (103%), and also As (86.5%) and Cd (96.7%). Three springs with elevated levels of B (730 µg/dm³), Li (210 µg/dm³) and Se (1.0-4.2 µg/dm³) were revealed, This suggests high prospects of bottling the water of these springs for utilization in preventive purposes as a table natural mineral water, intended for increasing immunity, preventing osteoporosis and in neurological practice.
