Concentration of major solutes in the thermal water for the two warm springs in Bürchau (B1 and B2). Concentration of major solutes in the thermal water expressed in millimoles per litre for the two warm springs in Bürchau (B1 and B2) compared to two representative high TDS deep fluids (dashed red lines), two intermediate mature waters from the transition group (dashed blue lines) and one similar low concentrated water from the Southern Black Forest (dashed black line). (Data from: Schmassmann et al. (1984) & Wittwer 1986, Carlé 1975, Stober 1994 and Stober and Vicedom 2005).
