Groundwater is a good source for human water requirement because it has low susceptibility to pollution and its natural availability is good when compared to surface water. Groundwater is primarily used for domestic, agriculture and industrial activities. Groundwater is a nonrenewable source and at same time over exploitation and pollution of groundwater is spoiling the groundwater. So developments of groundwater resource and prevention of contamination are prominent task in the groundwater management. The primary objective of the study is to map groundwater vulnerability of Palayamkottai taluk in Tirunelveli district Tamil Nadu by applying SINTACS model. This model uses the input from remote sensing and geographical information system (GIS) techniques. SINTACS model is based on overlay index methodology. The SINTACS model comprising of seven hydro geological parameters namely water table depth, net Recharge, unsaturated zone, soil media, aquifer media, hydraulic conductivity and slope. These parameters are integrated to delineate the area that is more susceptible to pollution. The SINTACS model classified the Palayamkottai taluk into low (108.1 km2) and moderate (191.9 km2) vulnerable area. |
