Bandung Basin is surrounded by volcanic mountains system. The Northern part bounded by Gn. Tangkuban Perahu and Burangrang, in the Southern bounded by Gn. Wayang Windu, Patuha, Kamojang and Talaga Bodas-Karaha. The volcanic activity associated with the presence of trace elements to the surface by hydrothermal fluids. This study aims to investigate the characteristics of water and the existence mechanisms of trace elements in volcanic regions around Bandung Basin using hidrogeokimia analysis. The method used for the analysis is major ion, trace elements, isotopes 18O and 2H, PHREEQC and XRF. The type of water in upflow zone is sulphate water and in outflow zone is bicarbonate water, Na-Cl water and sulphate water. The existence of trace elements (As, Li, B, F) derived from hydrothermal fluids and adsorption of clay minerals
