The water resources of small islands are often very limited. Many have no surface water resources and rely on limited underground water resources. This paper presents a hydrological research to the boundary of saline ground water inflow for Langkawi Island .A geophysical survey is carried out and underground soil are analysed for their conductivity at several points along the coastal area between Sungai Melaka and Sungai Chenang basin using "Transient Electromagnetic Technique (TEM) ". The conductivity test results signify the boundary of saline ground water intrusion throughout the area ( salt water has higher conductivity to fresh water ). Results from the survey indicate the potential areas for fresh water resources and the technique employed enables the mapping of salt water intrusion in the study area.
