Every time of the year the need for water always increases both for the needs of everyday human life and for animals, plants and industry and transportation. Increasing demand for clean water, the exploitation of ground water will also increa se, resulting in diminishing groundwater supplies. Reduced groundwater content in aquifer layers facilitates the entry of leachate and seawater into aquifers so that it has the potential to be polluted. The purpose of this study is to interpret the factors that cause intrusion of sea water and leachate into groundwater. The results of the study that showed correlation of field measurements with the laboratory showed that low value resistivity anomalies interpreted as zones of leachate saturation or saturated water zones and intrusion of seawater in the area around leachate columns were estimated to be connected to the lowlands, which had implications for the potential contamination of water reservoirs surface by leachate in distressed aquifer and polluted aquifer. Groundwater layers are interpreted to experience contamination identified at a depth of 5.0 - 12.0 meters. Key words: Resistivity, Ground Water, Groundwater Pollution, Intrusion, Leachate.
