title: Characteristics of formation of chemical composition of groundwater of active water exchange zone of the Bodrak catchment area (South-Western Crimea)
abstract: The article focuses on study of the chemical composition of the groundwater zone of active water&#13;\nexchange. The site of research was the Bodrak catchment area (South-Western Crimea). Formation&#13;\nof groundwater is caused by the infiltration of precipitation. Its chemical composition is influenced&#13;\nby natural and anthropogenic factors, but primarily it is determined by the enclosing sediments. At&#13;\nthe same time, a leading role belongs to the sand-and-clay and volcanic-sedimentar
