We were taking groundwater samples from a multi-layered aquifer system in the Lom depression of Danubian Plain in Bulgaria to find palaeowaters. Our aim is to model the past climate out of the Carpathian region.
In the field we can determine the general water chemistry parameters (temperature, pH, conductivity, redox potential, bicarbonate, calcium content) of the samples. In addition to the amount of anions and cations in the laboratory we can measure the stable carbon, hydrogen and oxygen isotope ratio, noble gas concentration and tritium and radiocarbon content. As an isotope climatological research centre we can determine the origin, recharge temperature, and age of the groundwater from the obtained results.
