The relevance of the study is caused by the obtaining of the previously unexplored isotope-hydrogeochemical data on the natural waters of the south-east slope of the Chekanovsky ridge (Arctic regions of the Siberian Platform). The study area is difficult due to the access continuous distribution of permafrost. The aim of the research is to identify the geochemical features of the natural waters of the south-east slope of the Chekanovsky ridge. Methods. Field sampling was carried out in accordance with generally accepted methods. Chemical analytical studies were performed by titrimetry, ion chromatography and inductively coupled plasma mass spectrometry. The analysis of the isotope ratios (δD, δ18O, and δ13СDIC) was carried out on an Isotope Ratio Mass Spectrometer FinniganTM MAT 253 equipped with H/Device (for analyzing δD ratios) and GasBench II (for analyzing δ18O and δ13СDIC ratios) sample preparation attachments. In the study of hydrogeochemical data, we used geochemical coefficients (Ca/Na, Ca/Mg, Ca/Si, Mg/Si, Na/Si, Si/Na, rNa/rCl and SO4/Cl), coefficients of concentration and water migration according to A.I.
