description Integrated geophysical, hydrochemistry and isotope hydrology have been used in this research to study the characteristics, origin and migration of contamination at Matang and Beriah landfill. Comparison studies of groundwater contamination for both landfill site categories were conducted for Matang landfill, level 3 (controlled landfill) and Beriah landfill, level 0 (uncontrolled landfill). The Electrical Resistivity Imaging method, supported by soil well logging data shows a subsurface image that provides clear indication of ground contamination zone. Low resistivity values were detected at line 1 in Beriah which is at the south west of the landfill. The resistivity value ranges indicate that the value ranges are from 20 to 50 Ωm (moderately low) at a depth of 10 m and less than 10 Ωm (very low) at a depth of greater than 10 m. Meanwhile, for Matang landfill, a significantly low resistivity value was observed in line 3 with a value <10 Ωm at 100 to 180m distance of the line and at the depth of 0 to 5m.
