Soil and groundwater pollution from anthropogenic activities poses a significant challenge to agricultural sustainability in rural areas, including Sukasari Village, Tanjungsari District, Sumedang Regency. This study aims to delineate contaminated zones and characterize contaminant distribution patterns through the integration of geoelectrical methods and soil physicochemical analysis. The geoelectrical survey was conducted along eight lines using a 48 electrode configuration with 1 meter spacing. The resistivity cross-sections revealed high-resistivity anomalies in the garden area located downslope of the settlement, indicating contaminant accumulation. This finding was supported by soil test results that confirmed the presence of pollutants, while the area around the biodigester remained relatively uncontaminated. The results indicate that the primary sources of contamination are household and agricultural activities in the southern settlement area, with contaminant migration toward the gardens and rice fields in the north. Overall, this study demonstrates that integrating geoelectrical methods and soil physicochemical analysis is an effective approach for mapping subsurface contamination and supporting sustainable agricultural land management.
