Groundwater monitoring as a tool of the hydrogeological cartography in Poland in the light of Water Framework Directive

The Hydrogeological Map of Poland, 1: 50,000 has been completed last year and it demands permanent updating in the future. The only source of the new hydrogeological data to this map can be provided by a groundwater monitoring system. The groundwater monitoring in Poland undergoes reconstruction according to Water Framework Directive (WFD) of the European Union. WFD is the general legal act oriented towards the sustainable utilization, protection and improvement of the state of water resources. Delineated groundwater bodies have to be monitored and the results are aimed for the action plans of the water management. Newly prepared directive “Groundwater vs. pollution” comprises more detailed procedures of monitoring, manners of sampling, elaboration of the results and presentation. It should be reflected also in the hydrogeological cartography.
