Sixteen water samples were collected from the river, spring, and hot spring at the West Tompaso in Minahasa Region, North Sulawesi, Indonesia. The water types were identified as Ca-HCO3, Ca-SO4, Na-HCO3, Na-SO4, and H-SO4. The samples water of TS-1, TS-02, TS-03, TS-04, WT-11, and T-12 are Ca-HCO3 type. The origin of this water type is shallow groundwater. Another water samples of TS-05, TS-06, TS-07, GS-13, GS-14, and GS-15 are Ca-SO4 type. These water types were identified as hot springs. Two samples of water of WT-10 and WT-16 are Na-HCO3 type. These waters come from the confined aquifer. The sample water of BK-08 is Na-SO4 type. This water is saline affected water and comes from the hot spring. BK-9 is H-SO4 type. This water type is steam-heated water and rich acidic water. All samples of water origin are shallow groundwater and surface water. Shallow groundwater model at the West Tompaso was developed.
