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

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.
