Quality and quantity status and risk assessment of groundwater bodies in the karst area of Croatia

Almost half of the Croatian territory belongs to the karst area of specific surface and underground morphological characteristics. It is exceptionally difficult to separate the groundwater from surface waters in karst areas. From that reasons karst areas require an integrated water quality and quantity assessment as well as water resources risk assessment for each groundwater body (GWB). In heterogeneous karst conditions there are considerable difficulties in delineation of GWBs as well as in assessment of the groundwater quality and quantity status which had to be performed according to the EU WFD. The fact that the groundwater monitoring in Croatia is in a developing stage is an additional problem, so that the initial characterization and groundwater risk assessment have been performed according to data from the 2000 – 2007 period. This paper presents the methodological approach which was applied on Croatian karst area as well as the abbreviated summary of conducted analyses.
