Technogenic hydrogeochemical anomalies within the influence area of industrial chemichal dumps

Abstract

The paper assesses a technogenic effect on groundwater chemical structure, produced by dumps of Gomel Chemical Plant. The role of controlled macrocomponents, presented by SO42–, PO43–, NH4+ and Cl–, which influence groundwater pollution is analyzed. For the first time the features of the distribution of heavy metals (Cu, Zn, Cr, Co, Pb, Cd, As, Hg) in the groundwater within the phosphogypsum dumps are considered. The levels of technogenic geochemical anomalies of elements-pollutants and their spatial differentiation and in the geological profile are found. Areas with different geochemical features on the main paths of groundwater flow are determined. Within these areas there is a possibility for some types of geochemical barriers, which may reduce the contrasts of hydrogeochemical anomalies.
