Radiocarbon and stable isotopes as groundwater tracers in the Danube river basin of SW Slovakia

Horizontal and vertical variations in the distribution of radiocarbon, d13C and d18O in groundwater of the Žitný island (Rye island) at the Danube River Basin, which is the largest groundwater reservoir in the Central Europe (about 10 Gm3), has been carried out using the geostatistical analysis of experimental isotope data. The core of the subsurface C-14 profile represents contemporary groundwater with C-14 values above 80 pMC, except a small area on the east of the island where C-14 values down to 40 pMC were observed, indicating a groundwater source outside of the direct Danube River influence. This has been for the first time when vertical distributions of isotopes in different groundwater horizons have been studied. This research is important for determination of the sources of milk and also for determination of authenticity of milk and its adulteration with water.

Examining riparian drinking water resources in the Danube basin

The research include stable isotopes of lihgt elements in order to determine the sources of drinking water that could be also used for milk adulteration.
