<p align="justify">The research sites located in the Tangkuban Perahu area and its surroundings, and with a landscape that is surrounded by many active volcanoes which can be found in both hot and cold springs associated with hydrothermal activity. Hydrogeochemical studies including major ion analysis, sulfur stable isotope &#948;34S from dissolved sulfate, and XRD analysis for precipitate to determine subsurface character in the study area. The dissolved sulfate composition contained in the sample of cold springs in the study area ranged from 0 to 649.8 ppm while hot water between 0 and 6427 ppm. The spatial distribution of cold spring samples and hot springs has a tendency to increase to the western segment of the Lembang Fault including Kancah and Tangkuban Perahu areas. The results of sulfur stable isotope analysis (&#948;34S) show values ranging from (-7.56 ‰) to (+0.06 ‰). Depleted values tend to refer to the sulfur isotope fractionation that oxidized from sulfides and tended to be disperse in marine sulfate systems and volcanic activity<p align="justify">
