Abstract

The final processing place of waste that open,in generally result leachate. The leachate uncontrolled will leak everywhere, so that can affect condition of groundwater around the landfill. The aim of this research is to determine contaminantion of  groundwater by leachate in that area. This research use resistivity geoelectrical  method with Schlumberger configuration. Data are colected in four track by ARES (Automatic Resistivity meter). Data are interpreted by the Smoothness Constraints Least Squares inversion method to obtain models of 2D the earth's surface. The result of this research showed that there has been contamination of groundwater by leachate in Air Dingin landfilling. Groundwater contamination occurs on every track measurement, except on track 2. Contamination was identification in the depth of 5,00-23,30 m with resistivity value less 10 Ωm.
