Regions formed in late Pleistocene usually show complex hydrogeological conditions. Groundwater circulation and the contribution of surface water in the groundwater flow system is not easy to determine. An important tool in such a research seems to be investigation of groundwater and surface water chemical composition. This paper is a case study of survey led in szymbarskie hills of the Kashubian Lake District (northern Poland). The groundwater and surface water quality was determined and analyzed with respect to conditions of groundwater circulation. The obtained results may contribute to development of groundwater investigations in young glacial areas.

The article presents the results of investigations conducted within NCN grant no. 2015/17/B/ST10/03233. The aim of the research is to access changes in the chemical composition of groundwater occurring in a glacial-outwash aquifer, on the basis of the natural hydrogeochemical background. The research includes the area of the Brda and Wda outwash plains belonging to the Tucholskie Forest mesoregion. The study compares the natural hydrogeochemical background identified 30 years ago with the current chemical composition of groundwater from the glacial outwash aquifer. Local changes were observed, expressed as an increase of the concentration of nitrate compounds, TDS and to a certain extent also chlorides and sulphates. In the remaining area, the chemical composition of the groundwater similar to the natural composition.

The article presents results of investigations carried out in the central, most elevated part of the Kashubian Lake District, in the area of the Szymbarskie Hills and the Ostrzyckie Lake. The occurrence of groundwater outflows is very diverse here; wide areas of young glacial elevations are free from springs, while large concentration of groundwater outflows is observed in the vicinity of trough lakes. Investigations of the outflows discharge and of the water chemical composition were carried out in the period of three years. Most of the analyzed springs are perennial, only a few of them are of periodic character. Comparison of the obtained results with the results of the research performed 40 years ago shows little diversity, without a clear trend to development or disappearance of groundwater outflows.
