The chemistry of water is determined by regional hydrogeological factors. In the marls and limestones of the Jędrzejów Plateau, Wodzisław Hummock and Pińczów Hummock, bicarbonate lime waters occur, with the main ion content of approximately 0.6 g/dm³. In the Solec Basin, sulphuric lime waters are quite common, which normally contain over 1.0 SO₄/dm³.
