Opis:
This article explores the current state of research in hydrogeology and the future challenges of fundamental and applied hydrogeology. A bibliometric analysis was conducted in the first part of the paper in order to evaluate groundwater research. It was based on papers published in Hydrogeology Journal and Journal of Hydrology in the period 2010–2014. This two journals were chosen arbitrary as most representatives for groundwater research for many reasons. The first journal published the largest number of articles and the second one has the highest percentage of publications related to groundwater research. Another reason was the field of research presented in this two journals: regional hydrogeology and methods. The bibliometric analysis summarizes output and research hotspots in groundwater studies. A keywords analysis showed that regional hydrogeology, methods and research techniques, isotopes and tracers and hydrogeochemistry were the main research areas in the study period. Then the citation data were used form these two journals and from the period 2001–2015 to assess the main areas of research. This analysis showed that methods of studies, recharge, ground water/surfaced water interaction and hydrogeochemistry were the main research areas in the studied period. The second part of this paper presents the main challenges for hydrogeology and it is based on many papers published in the period of last ten years. One of the greatest challenges in hydrogeology is fundamental science on regional scale .The demand is in determining universal theory on dominant processes on the regional scale, mainly with respect to groundwater recharge, groundwater/surface water interaction and transport processes. Finally the regional scale research imply interdisciplinary research.

Opis:
The major groundwater resources in Poland come from Quaternary aquifers. Rich in groundwater are structures of contemporary river valleys and of buried valleys, that comprise sands and gravels of glaciofluvial origin. Groundwater aquifers cover water demands of ca. 2.1 km3 annually. 65% of drinking water in Poland comes from groundwater intakes. Recharge zones of these aquifers are usually located in highlands – moraine plateau, and discharge zones are located in deep and wide river valleys. The average thickness of fresh water aquifers is about 200 m in Poland. The fresh water was stated even over 1,000 m depth in some places, but in the Mesozoic strata. The thickness of fresh water aquifer reduces, however, to only few metres in areas of salt water ascension or intrusion along the Baltic coast area. Recognition of groundwater circulation systems is the basis for delineation of a groundwater body (GWB). In Poland, the most productive parts of groundwater bodies that allow to abstract water at a rate grater that 10,000 m3/day, are defined as Major Groundwater Basins (MGWBs). The mean residence time of groundwater in Quaternary aquifers in Poland is estimated at some 50 yrs, whereas the residence time of water in sluggish circulation systems in deeper strata exceeds 104 yrs. Quaternary aquifers situated close to the surface area are vulnerable to municipal and agricultural pollution. The geogenic pollution such as sea water intrusion or ascension of brines are observed mainly at lowlands along the Baltic coastline, in vicinity of water intakes, or on an axial zone of anticlinoria. Trends in lowering a groundwater table are noted in the central part of the Polish lowlands and are associated with climatic variability or lignite opencast dewatering.
