Climate factors of groundwater formation: a case study of the Lower Don

Abstract

Natural factors play an important role in the formation of the chemical composition and allocation of hydrogeochemical classes of groundwater in the Lower Don basin. The most resistant to human effects are groundwater of Sarmatian complex. The prospect of improving the quality of drinking water supply is associated with the involvement of groundwater in water management, but they are characterized by high hardness. Groundwater is influenced by geology, climate, biology, soil, and etc. Understanding the groundwater regime and pathways is essential because groundwater join and mixes with river water.
