Infiltration of Lake Water into the Groundwater System Investigated by Tritium/Helium-3 Method: An Example from Wannsee and Lieper Bucht Area, Berlin, Germany

Author(s): Hany El-Gamal, Jürgen Sültenfuß

The T/3He ages were calculated for groundwater samples collected from the locations Wannsee and Lieper Bucht area, southwestern Berlin, Germany. The calculated ages were used to study the infiltration of lake water into the groundwater system. The results showed that the distance of the wells from the bank of the lake does not affect the calculated ages, especially for the deep wells where all deep wells have nearly the same age. The shallow wells, which have ages nearly one year, have stable tritium of 11-12 TU, while the deep wells with ages nearly 24 years have stable tritium of 15-25 TU.
