Summary:The chemical evolution of groundwater in the River Danube deposits was investigated using the computer model PHREEQM, major and trace element analysis, dissolved gas determination, and carbon hydrogen and oxygen isotopic measurements. Water chemistry suggested that groundwater flows from W to E. Cation exchange was a major influence on the chemical composition of the groundwater. In the recharge area groundwater chemistry was controlled by dissolution of calcite and dolomite and the weathering of albite, whilst in the discharge area the main process was multicomponent cation exchange. At the end of the flowpath water composition was controlled by the mixing of flowing groundwater with old formation water. Groundwater age and modelling indicated that the present groundwater began to flush out former groundwater 40 000 B.P. Flushing was caused by high rainfall between 40 000 and 50 000 B.P. and tectonic uplift in the Pleistocene.
