The water levels of the thermal springs and the ground water levels were measured and the contour of the water table was obtained. The contour was disturbed at two regions in which many springs issue. The thermal and ground waters were sampled all over the springs district, and the water temperatures were measured when they were sampled. The chloride, bicarbonate, sulfate, calcium and magnesium content was also determined. In addition, the analytical methods for the determination of arsenic, phosphorus and acid-soluble iron were improved. Also the concentration of these elements was determined. Based on the results of the observations and chemical analysis, the relations between the water temperatures and content of chemical constituent and the chloride content were checked respectively. Positive correlations were found in the relations between water temperature~Cl(-), HCO(3)(-)~Cl(-), SO(4)(2-)~Cl(-), Ca(2+)~Cl(-), and As~Cl(-). Furthermore, the regional differences were detectable in the ratios of water temperature to chloride content and of bicarbonate to chloride content, nevertheless the correlation as a whole were valid. The diversity and regional differences of the chemical composition of the waters were explained as due to the differences in the mixing proportion of the magmatic thermal water and the varying kinds of ground water at the deep site in the ground and at the site near the ground surfaces.
