Chemical composition of selected water samples from the southern Black Forest reveals increasing ion-concentration and water type changes from near-surface Ca-HCO3-type (e.g. Wilhelminenstollen, Menzenschwand, Bürchau) (Rolker et al. 2015 and this study) to an Na–Cl water-type (different depth sections in Bad Säckingen and Schönmatt, data from Stober (1995), Stober and Bucher (2014), and Rolker et al. (2015)
