Isotopic investigations in the area of the Union brewery water body
Abstract
A study of groundwater flow and solute transport commenced in the area of the Union Brewery water body in 2003 with the intention of a) assessing and predicting the movement of groundwater and urban contaminants through the Pleistocene alluvial gravel aquiferand of b) analysing the risk of contaminat transport to drinking-water resources in the lower gravel aquifer. The first two research phases based on isotopic researches. The monitoring of groundwater composition of δ18O in δ2H stable isotopes and basic physicochemicalparameters was established in 16 observation wells. The results have produced general information on the hydrodynamic functioning of the study area and they provided,an insight into age structure of sampled water. The vertical flow component was identified,which is the main influence on contaminant transport towards the drinking-water resource.
