Trace elements in the groundwater in the Hungárián Southern Great Plain Hrabovszki, E. Abstract: In the Békés and Csongrád county trace element concentrations of Pleistiocene groundwater have been determined. Cluster analysis has been performed to separate the areas characterized by different types of water quality. The possible geochemical processes, that could have been resposible for the water quality have been identified by principal component analysis. According to the result, concentrations of the trace elements are controlled by dissolution of carbonates, irreversible albite wheathering, formation of secondary minerals and redox processes. These hydrogeological factors differently effect the origin and concentration of Al, As, Zn, Fe, Mn, Sr, Ba, Li and Sí in the studied groundwaters.
