Ecological-hydrogeochemical estimation of the condition of the neogene-quarternary waterfall complex of the south-eastern part of Voronezh city

Abstract

The article provides a comprehensive assessment of the state of the Neogene-Quaternary aquifer complex in the south-eastern part of the city of Voronezh in accordance with the methods of ecological and geological studies, an integrated assessment of the transformation of groundwater, and the construction of three-dimensional models of the day surface of the earth and the base of the Neogene-Quaternary aquifer complex. As a result, the groundwater status of the investigated area is estimated as not appropriate for drinking water supply purposes. The area of pollution of the Neogene-Quaternary aquifer complex in the period 1992-2015. varies from 18 to 22 km2. Pollution of groundwater is the main environmental problem of the studied area. All the pollutants of the Neogene-Quaternary aquifer complex were detected: sodium, boron, bromine, surfactants, iron, manganese. The three-dimensional model of the day surface and the basement of the Neogene-Quaternary aquifer complex made it possible to identify areas of accumulation of pollutants: the area of the former filtration fields, treatment facilities, dachas, tire plant, and the Rudgormash plant.
