Sažetak
According to the EU Water Framework Directive, groundwater has a good status if anthropogenic changes do not significantly endanger surface waters connected to them and do not significantly harm terrestrial ecosystems dependent on them. A status assessment of groundwater bodies (GWB) from the standpoint of groundwater-associated aquatic ecosystems (GWAAE) and groundwater-dependent terrestrial ecosystems (GDTE) was made for Croatian Waters (Hrvatske vode) and needs of River Basin Management Plan for the period 2016 – 2021. GWAAE and GWDTE were isolated, and a methodology for a status assessment of associated groundwater was defined. The methodology for risk assessment indicates failure to achieve a good status if the groundwater status is not satisfactory or a risk of failure to achieve the goal of "preventing status deterioration" if the groundwater status is satisfactory, but there is large pressure on the groundwater. The interconnection of groundwater with surface waters is characteristic of almost all GWBs in Croatia. In karst areas, groundwater-dependent aquatic ecosystems (springs and speleological objects) predominate, while in the Pannonian part of Croatia, there are groundwater-dependent terrestrial ecosystems. The groundwater status and risk assessment were analysed from two standpoints – the quantity and quality of groundwater. On the basis of the proposed methodologies in all GWBs, the status was defined as good. One GWB was marked as being at risk. The reliability of these assessments is often low because of low data availability. A proposition for research monitoring was developed, with the purpose of more thoroughly defining the groundwater status with dependent ecosystems in the future.
