The study area falls under South Andaman district, which is one of the 3 districts of the Union Territory of Andaman & Nicobar Islands located in the Bay of Bengal. The district of South Andaman comprises three Tehsils Portblair, Ferrarganj and Little Andaman. Portblair is the district head quarter and capital of the Union Territory. The area Shaheed Dweep and Swaraj Dweep is underlain mainly by Coralline limestone which is basically resting on claystone. The latter forming the basement also outcrops as small hills in pockets. Because of high permeability coralline limestone form good aquifer, while the basement does not contain fresh water because of less permeability & Transmissivity. The freshwater is negligible in the basement, and consequently brackish/ saline water is also found in the formation.
