Ecological-hydrogeochemical assessment of the aqueous upper pliocene terrigenous horizon condition in the area of village Medovka Ramonsky district of Voronezh region

Abstract

The article presents an ecological-hydrogeochemical assement of the aqueous upper Pliocene terrigenous horison condition in the area of village Medovka Ramonsky district of Voronezh region, based on the study of the ecological functions of groundwater. Considered and given: resource environmental assessment, environmental and hydrogeochemical assessment, environmental and geophysical assessment, environmental and hydrodynamic assessment. Resource environmental assessment showed the presence of groundwater in the volume and quality necessary to meet the needs of the population. The sizes of three zones of sanitary protection zones are calculated. The discrepancy between the quality of groundwater and turbidity, acid-base balance, iron and nitrates was revealed. Ecological and geophysical assessment of groundwater quality revealed their permissible condition. The hydrodynamic indices of the aquifer under study were calculated: the average value of the allowable decrease for the site, the decrease in the level of the underground as a result of the operation of the water intake, the hydrodynamic potential, provided that the existing water supply system is maintained. Based on the results obtained, a scheme of environmental measures for the Upper Pliocene terrigenous aquifer in the studied area was formed.
