The marginal moraine areas of continental glaciation are lithologically notable for great variations in surface deposits. If such Quaternary deposits are deeply cut by river valleys and ravines, their slopes and terraces make favourable conditions for groundwater to be exposed and to form springs. Most often such springs are of a falling type, i. e. water streams under the influence of gravitation.
In the ancient times people used spring water for drinking and preparation of food, since it was clean and tasty. Such an image of spring water has remained up to the present days, although due to increased pollution of the environment, the water of such springs can be both good and bad. Regardless of this, people bring it to their homes thinking that spring water is of a better quality than that provided
by the municipal water supply. Such practice is also widely exercised in Vilnius, where the geomorphological conditions are favourable for springs to be formed. Therefore, Hydrology and Engineering Geology Department of Vilnius University have analysed the chemical composition of the city spring waters and assessed their quality in respect of the quality of water suitable for drinking.
