This study focuses on the spatial analysis of shallow groundwater quality after disaster on september 28, 2018 for sustainable drinking water management in Palu City. This study aims to spatially map shallow groundwater quality zones based on groundwater quality criteria for drinking water as stipulated in the Regulation of the Minister of Health of the Republic of Indonesia Number 2 of 2023 by employing the pollution index (IP) method, the Water Quality Index (WQI), and the STORET method, alongside a correlation analysis using standard deviation. The research evaluation based on 60 shallow groundwater samples with a proportional random sampling method especially the liquefaction disaster. The results of the study show that: 1). Average parameter values for Palu City are as follows: (TDS 414.41 mg/l, pH 6.80, Fe 1.10 mg/l, Mn 0.80 mg/l, Pb 0.02 mg/l, NO3 1.00 mg/l, dan NO2 1.32 mg/l). Based on Minister of Health of the Republic of Indonesia Number 2 of 2023, the quality of shallow groundwater in the study area generally meets the requirements for drinking water. However, the results of tests for certain parameters show high values, particularly in the Balaroa and Petobo liquefaction areas. 2). The pollution index the average sample the range of 1.0 < PIj ≤ 5.0, thus categorizing the groundwater quality in the study area as lightly polluted. Some groundwater values ranged from 5.0 < IP ≤ 10.0 in the Petobo liquefaction area, 3). The WQI index classification, the very good category has a value between 0-25 for TDS, pH, Fe, NO3, and NO2. Mn are bad with WQI values of 51-75 only Pb is not fit for consumption with WQI values > 100. 4).The STORET method, the quality of shallow groundwater in the research area is included in the class B category: good: score -1 to -10 = lightly polluted. It can be concluded that, in general shallow groundwater in the study area meets the requirements for drinking water. However, in areas affected by liquefaction such as Balaroa and Petobo the values of certain parameters were found to be higher. Consequently, shallow groundwater sources in these post liquefaction locations are not recommended for use as drinking water.
