    • Abstract

       

      A group of 36 coral islands is being scattered in the Arabian Sea of the western coast of India. On such islands,groundwater is the only source of fresh water for the islanders.The demand for groundwater is increasing every year due to growing population and urbanization.On the other side the peculiar hydrologic,geologic and geomorphic features restrict the availability of groundwater. Thus a proper understanding of the groundwater condition is important in order to meet this increasing demand and also to formulate future development and management strategies.Detailed hydrogeological,geophysical and hydrochemical studies had been carried out to identify potential fresh groundwater resources and quantify vulnerable parts of Andrott Island,Union Territory of Lakshadweep.Systematic collection and analysis of hydrological,geophysical and hydrochemical data gives an early signal of deterioration in groundwater quality in the peripheral parts of eastern and western coasts of this island and it suggests immediate measures for arresting the deterioration in groundwater quality as well as augmentation for restoration of aquifer in some parts of the island.
