Abstract

The concentrations of tritium, helium isotopes and neon have been measured in groundwater samples from a shallow and deep groundwater system recharged by bank infiltration from the Oder River in northeastern Berlin, Germany. The apparent ³H/³He ages show a distinct variation. They increased from only a few months to >40 years along the flow path. The farthest wells from the river have high concentration of ⁴He terrigenic which is around 5 × 10^?5 (ccSTP/kg). The highest values for stable ³H (³H + ³He_trit) were encountered at a 2.6 kmdistance from the river.
