The aim of this report was to develop the principles of designing the Polish-Ukrainian and Estonian-Latvian transboundary groundwater monitoring network in relation to the needs of assessing their quantitative and chemical status. The recommendations were developed taking into account the potential of the existing national networks and the requirement of EU law. This report is the implementation of the first stage of creating the internationally integrated monitoring of transboundary groundwater reservoirs. The development of a joint program for monitoring the state of transboundary aquifers, which is also the task of the EU-WATERRES project. The developed guidelines of the organization of the transboundary groundwater monitoring network are aimed at helping the national authorities responsible for monitoring groundwater in implementing the issue of transboundary monitoring. In addition, the key target group are the institutions responsible for the management of transboundary groundwater reservoirs at the national and international level and the organizations responsible for the environmental issues in terms of transboundary impacts.
The aim of the document is to create a conceptual understanding of the hydrogeological processes and flow dynamics across the national borders in two different pilot territories - Polish-Ukrainian and Latvian-Estonian border area. Within the framework of this report, assessment of transboundary groundwater resources, as well as the determination of groundwater flow volumes across the state borders has been carried out. The report has been developed by seven project partners: Polish Geological Institute - National Research Institute, Latvian Environment, Geology and Meteorology Centre, University of Latvia, State Enterprise "Ukrainian Geological Company", Geological Survey of Estonia, The Institute of Geology and Geochemistry of Combustible Minerals of National Academy of Sciences of Ukraine and DC of NJSC "NADRA UKRAJYNY" "Zahidukrgeologiya".
