The thermal mineral water source is at karstic-fractured limstones of Dong Giao Formation aged Anisi. Methods used in this study conists of basic field survey of hydrogeology, resistivity, borehole drilling, pumping tests, and thermal mineral water sample analysis. The thermal mineral water is classified as radon-radium, low mineralised thermal mineral water.
