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.

The results of researches conducted in coastal area of the Przyladek Rozewie, were presented in this paper. The monitoring of physicochemical properties and ionic composition of groundwater outflows was carried out in the years 2013–2014 in the investigated area. Hydrogeochemical conditions of the Przyladek Rozewie region is mainly formed by lots of factors like specific marine climate, mineral composition of groundwater medium, depth of groundwater circulation and time of contact between water and rock.

In the years 2000–2004, a spring-hydrological research was carried out in the southern part of the Parsęta catchment located in the Drawsko Lakeland, Białogard Plain and Łobez Upland. During hydrochemical mapping performed in 2004, 117 natural groundwater outflows were sampled. The main aim of the study was to determine factors controlling the chemical composition of outflows and to show the influence of the water flow system on water chemistry in a drainage area. The predominant ions in the groundwater outflows were calcium cations and bicarbonate anions, and in the shallow groundwater also sulphates. Factor analysis showed that the basic control of groundwater chemistry was process of chemical weathering (i.e. weathering of aluminosilicates and carbonates, ion exchange) of morainic and fluvioglacial deposits which determined the concentrations of ions such as Ca, Mg, HCO3, and SiO2. Soluble ions are released by decay of organic matter (NO3, SO4, and SiO2) and atmospheric deposition (Cl, SO4, and NO3). Man-made supply locally corresponds to high levels of SO4, Cl, and NO3 ions. The outflows are fed by the near-surface aquifer (local flow system) and intermorainic aquifer (intermediate flow system). The small differences in the water quality of those aquifers resulted from the similarity of their hydrogeochemical environments and were also indicative of their hydraulic connection.
