The Rumpin Utara region of West Java presents a complex geological and hydrogeological setting that is crucial for local water resource management. This study aims to analyze these characteristics and their implications for sustainable groundwater utilization. Through field surveys, borehole data, and geoelectric measurements, this research identifies significant lithological variations and three distinct resistivity zones affecting groundwater potential. The findings highlight the necessity of careful groundwater management to address challenges such as water scarcity and declining water quality, thus contributing to more effective resource planning in the area. Field surveys, borehole logs, and geoelectric surveys revealed significant lithological variations due to fault structures affecting groundwater distribution. The identification of three resistivity zones indicates substantial groundwater potential, reflecting variations in rock layers and groundwater availability. Low resistivity zones (< 24.8 Ω.m) include soil and clay, medium resistivity zones (24.8 – 60.0 Ω.m) consist of sand and silt, while high resistivity zones (> 60.0 Ω.m) encompass sandy claystone and compact claystone. The depth to the groundwater table in this area varies from –2.5 to –20 meters, with groundwater quality generally being fresh, with neutral to slightly acidic pH, and variable electrical conductivity. There are more than four aquifer layers with thicknesses ranging from 5 to 15 meters, indicating significant groundwater potential but requiring careful management to ensure sustainable water supply.
