“…It means that the condition peculiar to the underground hydrosphere, and primarily, to the groundwater, as the first constant water-bearing formation, may serve as an indicator of the ecological state of the geological environment as a whole. Nowadays, it is believed that the functioning of a scientifically grounded stationary system of hydro-geological monitoring supplies the most complete information about the groundwater condition [Koshliakov et al 2016, Shestopalov et al 2016]. However, since such system is practically absent in the most territories of Ukraine, and in the studied Ivano-Frankivsk region in particular, and its creation and effective functioning is problematic because of purely economic reasons, we have to develop the new approaches to obtain and process information on the groundwater conditions, as well as on the dynamics of their levels first of all.…”
