Abstract The potential role of processes discriminating S isotopes, for example dissimilatory SO4 2- reduction and mineralization, in determining SO4 2- concentrations was studied in forest spring water. S-isotope composition of sulfate from atmospheric input and forest springs representing a wide range of SO4 2- concentrations was investigated in the Fichtelgebirge (NE Bavaria, Germany). δ34 S values in atmospheric input ranged from +3.7 to - 5.7‰. In spring waters with SO4 2- > 150 μmol 1−1 δ34 S values were between +4 and -5‰. whereas δ34 S values increased up to +7.2‰ below 150 μmol 1−1 SO4 2-. SO4 2- mineralization seemed to have no effect on isotopic composition since all δ34 S values of spring water were higher than input values. Dissimilatory SO4 2- reduction occurred in springs with SO4 2- < 150 μmol1−1. Spatial heterogeneity in forest soils or flow paths has to be invoked to explain increased δ34 S values since NO3 - concentrations would not allow for SO4 2- reduction to occur.
