Ground water pollution cause of the leachate seep came from landfills is a serious threat for environment and the health of local people.The research from various location of landfills shows that geoelectrical methods resistivity is a geophysics tools that effective to identified the distribution and flow pattern of leachate below the surface without ruin the soil structure.Common methods that being used on this sumption is implicate wenner, schlumberger configuration that have cross-section view 2D resistivity.Data processing usually use a software such as Res2Dinv.The interpretation results shows consistent that pollution zone cause by leachate mark with lower resistivity value, usually below 10 Ωm.Various research shows that the mark of leachate are average between 4-6 Ωm in a gap 17-19 meter.leachate discovered leaking in the depth up to 4 meter and tend to follow topographic slope to a lower plain.
