GROUNDWATER EXCHANGE IN THE BALTIC SHIELD MARGINAL AREAS AND ADJACENT ARTESIAN BASINS BASED ON ISOTOPE AND HYDROCHEMISTRY DATA. SCIENTIFIC PROBLEMS AND PRACTICAL APPLICATIONS. KARELIAN ISTHMUS
Water chemical and isotopic composition (deuterium content and oxygen-18), as well as the activity of tritium in groundwater of Riphean aquifer and Vendian complex in the Karelian Isthmus were studied. Estimation of recharge rate for groundwater of the Vendian complex by tritium yielded groundwater...
