Mapping leachate’s distribution using geoelectrical resistivity has been done at Plesungan village, Gondang Rejo, Karanganyar regency. Acquisition using Wenner-Schlumberger configuration with space of the smallest electrode is 15 meters away. This research using resistivitymeter OYO McOHM-EL for current injection and measure the potential difference. Inversion process using Res2dInv software for 2 dimensions model and RockWorks16 software for 3 dimensions model. The location of the research has geology old alluvium with characteristics conglomerate, sandstone, silt and clay. Leachate mapping estimated resistivity value <5.55 ohm meter with the direction away from the final disposal site where the main constituent of reseach sites is clay.
