Springs of the Widawka Drainage Basin

In this article the authors have presented the zones in which springs occur (fig. l). They have divided the researched springs into morphogenetic types and indicated a dependence of the different types of the spring water outflows upon height-intervals. The analysis shows that the springs with the biggest outflows of water are related to the abundance of underground water horizons (tab. l). The outflows selected from different types were researched in a physico-chemical way (tab. 2). From among the 10 springs examined in a physico-chemicaI way in 1996, six are typical outflows from the Quaternary deposits (points 1-6), two are supplied with water both from the Quaternary deposits and from the Jurassic ones (points 8 and 9) and the last two are typical outflows from the Jurassic limestones (points 7 and 10). The physico-chemical researches of the springs in the Widawka drainage basin have shown that the predominant physico-chemical types are: HCO]-S04-Ca, HCO]-Ca (tab. 2, 4, 5; fig. 3, 4). The spring water quality analysis has proved that in all the cases the standards for potable water and economic purposes established by the Ministry of Health were satisfying (tab. 6). The water quality classification made according to the rules suitable for the environmenta
