Dating groundwater in the Bohemian Cretaceous Basin: Understanding tracer variations in the subsurface
Original language description
The understanding of groundwater flow and age distribution is crucial for the prediction of the future dispersion and impact of the contamination. State of the art tracer methods (3H, 3He, 4He, 85Kr, 39Ar and 14C) were used to obtain insights to ageing and mixing processes of groundwater along a north?south flow line in the centre of the two most important aquifers of Cenomanian and middle Turonian age of the Bohemian Cretaceous Basin. Dating of groundwater is particularly complex in this area as: (i) groundwater in the Cenomanian aquifer is locally affected by fluxes of geogenic and biogenic gases (e.g. CO2, CH4, He) and by fossil brines in basement rocks rich in Cl and SO4; (ii) a thick unsaturated zone overlays the Turonian aquifer; (iii) a periglacial climate and permafrost conditions prevailed during the Last Glacial Maximum, and iv) the wells are mostly screened over large depth intervals. An inverse modelling approach was used to estimate the age of groundwater. Best fits betwee
