Deuterium and oxygen- 18 values of the thermal waters indicate that they recharged locally and became K271enriched in oxygen-18 by exchange with rock. The isotopic composition of the waters indicates that they are of meteoric origin. A plot of deuterium versus chloride indicates that as the chloride concentration increases, the deuterium composition remains essentially constant. A plot of oxygen-18 versus chloride shows that the oxygen isotopes become more enriched as the chloride concentration increases. Tritium data are consistent with the presence of two water types and show that the waters are little mixed because no intermediate tritium values are present.
