N2 - Large variations were observed in Ba, Sr, Cl and SO4 concentrations in water samples collected at depth intervals of <9 cm below the water-table of a deep phreatic aquifer. It is suggested that the Sr and Ba concentrations in ground-water are controlled by dissolution of Sr-rich low Mg-calcite and BaSO4. The transition from saturated to undersaturated conditions with respect to barite occurs within a depth interval of only 50 cm. Microscale heterogeneity of ground-water demonstrates that samples obtained from pumping wells maynnot be suitable for either evaluating mineral equilibrium and water-rock interaction in aquifers, or for monitoring the fate of radionuclides in porous media.
