Analysis of pollution indices, predictions of the distribution of pollution loads, and the factors that most influence groundwater pollution are important to explain further as mitigation and conservation efforts for groundwater, which is used as a source of drinking water for the people of Wanuawaru Village, Bone Regency. Groundwater Pollution Conditions can be obtained by calculating each sampling point’s pollution index value. Next, an analysis was carried out using the Inverse Distance Weighting (IDW) approach using a Geographic Information System to determine the distribution of the spatial load of soil water pollution. Meanwhile, statistical analysis was carried out using Structural Equation Modeling (SEM) to determine the factors that most influence soil water pollution. The results showed that the pollution index value at the third sampling point was in the lightly polluted category (5.0 ≤ Pij ≤ 10) with the pollutant load concentration at the first point being 6.65, the second point 8.04, and the third point 9.84. By referring to the analysis of spatial results, the highest pollution load is at the third sampling point, which is recommended to be the primary focus in controlling groundwater pollution in addition to massive control efforts at points 1 and 2. Furthermore, the factors that influence groundwater pollution most are chemical variables with a coefficient of 0.890, biological variables with an effect of 0.337, and physical variables that tend to reduce pollutants by 0.255. Sustainable mitigation and conservation efforts can be carried out through more comprehensive water treatment, public education, protection of water sources, ecosystem rehabilitation, and integrated monitoring with technology that can effectively maintain groundwater quality and reduce negative impacts on health and the environment. © 2025, Thai Society of Higher Eduation Institutes on Environment.
