Abstract
Geothermal fluid carries the heavy metal elements to the surface, one of which is arsenic (As). Arsenic can be found naturally in the earth crust, exist on soil and mineral then can be enter on air, water, and surface environment. In the form of gases, Arsenic are associated with temperature of rock, a volatile element, and which only release on high temperature. In this research, we would to study about arsenic characteristic, arsenic mobilization, and the scheme how arsenic gases can be release on surface with several conditions. Based on references, in Chile, at volcanic area, says the arsenic gas content release with the area which have a high temperature and have several conditions on manifestation type. Then from twice validation on different geothermal area on Indonesia, we get same correlation with the references. Based on that, we assume the arsenic gas content on geothermal area is correlated with high temperature of rock, in a general we called it a heat source.
