Hydrogeologists from the Institute of Earth Sciences are continuing their fieldwork in Zgorzelec as part of the CRossWATER project, funded under the Interreg Poland-Saxony programme. Following the first pilot studies carried out in summer 2025, which included extensive investigations, field measurements and chemical analyses of groundwater and surface water on both sides of the Polish-German border, the research has now entered its next phase.
Since December 2025, systematic monthly water monitoring has been implemented, aimed at capturing the seasonal variability of hydrological and hydrogeological conditions. Regular measurements allow for ongoing assessment of interactions between groundwater and surface water, as well as a better understanding of flow dynamics within the transboundary water system.
During the most recent field campaign, in addition to standard water sampling and measurements of physicochemical parameters, detailed geodetic surveys were also conducted. Their purpose was to precisely determine the elevations of monitoring points and to verify hydraulic conditions in the study area, providing an important complement to the hydrogeological analyses carried out so far. New temporary staff gauges were also installed at the infiltration ponds, which feed the shallow aquifer of the well field in Zgorzelec.
The ongoing work aligns with the main objectives of the project, which include the development of an integrated monitoring system and an improved understanding of processes occurring within the transboundary groundwater system.
