Abstract
Lack of quality drinking water is a problem for the western part of the Novosibirsk Region (Russia), where the total mineralization of water varies from 1.5 to 3-4 g/L and sometimes higher. The search for near-surface aquifers with high-quality groundwater can be successfully carried out using electrical tomography. To understand the relationship between groundwater of different depths, the isotopic characteristics (δ18O and δD) of the waters of existing wells was studied. The groundwater studied is likely to have a common origin.

Summary
Lack of quality drinking water is a problem for many regions of the planet. It is relevant for the western part of the Novosibirsk Region (Russia), where the total mineralization of both groundwater and surface water is predominantly high and varies from 1.5 to 3-4 g/L and sometimes higher. The high salinity is mainly due to the marine geochemical conditions of sedimentation of aquifers. In this region, especially in small settlements, groundwater from deep aquifers is a main source of water both for agriculture and for drinking purposes. The geophysical methods have a drawback, i.e. they only allow to outline an area saturated with low-salinity water. Isotopic characteristics of groundwater for the western part of the Novosibirsk Region have never been analyzed before
