The water types were identified as Ca-HCO 3 , Ca-SO 4 , Na-HCO 3 , Na-SO 4 , and H-SO 4 . The samples water of TS-1, TS-02, TS-03, TS-04, WT-11, and T-12 are Ca-HCO 3 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-SO 4 type. These water types were identified as hot springs. Two samples of water of WT-10 and WT-16 are Na-HCO 3 type. These waters come from the confined aquifer. The sample water of BK-08 is Na-SO 4 type. This water is saline affected water and comes from the hot spring. BK-9 is H-SO 4 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. ## Keywords - Groundwater - Spring (device) - Surface water - Aquifer - Waves and shallow water - Saline water - Hot spring - Environmental chemistry - Chemistry - Hydrology (agriculture) - Environmental science - Geology - Environmental engineering - Salinity - Oceanography - Physics - Paleontology - Geotechnical engineering - Thermodynamics --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
