Groundwaters in the area of a mixed landfill (domestic waste above uranium mill tailings) in Dresden (Saxony, Germany) were investigated for their isotope signatures to distinguish between different groundwater types. To determine between the two contamination sources (waste and uranium mill tailings) a multi parameter interpretation was done using both, the main hydrochemical parameters the radionuclides 234U, 238U, 226Ra and 222Rn as well as the environmental isotopes of the elements hydrogen, oxygen, sulphur and carbon. The seepage water from the landfill shows higher delta34S, delta18O and tritium values as the inflow. The tritium values give an idea about water movement in the dump and mean residence time of the groundwater. The water in the dump shows varying delta13C values which indicate different processes occurring in the dump.
对德国萨克森州德累斯顿一处混合垃圾填埋场（生活垃圾位于铀矿尾矿之上）区域的地下水进行了同位素特征调查，以区分不同类型的地下水。为确定两种污染源（垃圾和铀矿尾矿），利用主要水化学参数、放射性核素234U、238U、226Ra和222Rn以及氢、氧、硫和碳元素的环境同位素进行了多参数解释。来自垃圾填埋场的渗流水显示出比流入水更高的δ34S、δ18O和氚值。氚值反映了垃圾场中的水流运动以及地下水的平均停留时间。垃圾场中的水显示出变化的δ13C值，这表明垃圾场中发生了不同的过程。
