GEOCHEMICAL FEATURES OF THE NATURAL WATERS OF SALEKHARD (YAMALO-NENETS AUTONOMOUS DISTRICT) IN THE SUMMER OF 2023

The report presents the results of studies on the major- and trace-component compositions of surface and groundwater in Salekhard in summer 2023. The tested natural waters are ultra-fresh and fresh (salinity 32-192 mg/l), hydrocarbonate with a mixed cationic composition. Surface waters varied from acidic and slightly acidic in the inter-temperate period to neutral and slightly alkaline in the end of the summer period. In the period under review, the maximum permissible concentrations of 13 trace-elements were observed, which requires the organization of systematic observations.
