Isotopic characteristics (δ18O and δD) of surface and groundwater as an additional tool for searching quality drinking water (Western part of Novosibirsk Region, Russia)

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 (δ 18 O and δD) of the waters of existing wells was studied. The groundwater studied is likely to have a common origin.
