Abstract For water samples from mining lake ML 111 of the Lusatian Lignite District and surrounding aquifers δ34S(SO4 b), δ15N(NH4 +), δD, and δ18O (H2O) values have been determined to asess the flow dynamic of the in- and outflow scenario. The high mineralization and acidification (pH > 2.6) of the lake water results from an intensive interaction with the surrounding dump sites and the inflow of extremely sulfate rich dump water (up to 4,100mg/1 SO4 ). δ34S values range from −7‰ to + 7°CDT in the inflow aquifers. The lake water is considered to be a mixture of different water bodies. The evaporation signature in the outflow aquifer suggests that the groundwater consists of 60% lake water. The nitrogen transfer is explained by 15N signature of ammonium. Sulfate reduction, perceptible in outflow and dump aquifer, cannot be proved within the mining lake by 34S and hydrochemistry.
