For this purpose, 59 groundwater samples were collected and analyzed for pH, electrical conductivity (EC), total dissolved solids (TDS), major anions (HCO 3 - ,CO 3 - - ,F - ,Cl ,NO 2 - , and SO 4 2- ), major cations (Ca 2? Mg 2? ,Na ? ), alkalinity (ALK), and hardness (HAR). To assess the water quality, the following chemical parameters were calculated based on the analytical results, such as Piper plot, water quality index (WQI), sodium adsorption ratio (SAR), magnesium hazard (MH), Kelly index (KI), and residual sodium carbonate (RSC). Wilcox diagram represents that 23% of the samples are excellent to good, 40% of the samples are good to permissible, 10% of the samples are permissible to doubtful, 24% of the samples are doubtful unsuitable, and only 3% of the samples are unsuitable for irrigation. SAR values shows that 52% of the samples indicate high-to-very high and low-to-medium alkali water. KI values indicate good quality (30%) and not suitable (70%) for irrigation purposes. RSC values indicate that 89% of samples are suitable for irrigation purposes. MH reveals that 17% suitable and 83% samples are not suitable for irrigation purposes and for domestic purposes the excellent (8%), good (48%), and poor (44%).

Assessing the ground water potential zone is very important for the protection of water and management of groundwater system. Recent trends are showing the systematic planning to stop the over exploitation of groundwater and shrinking natural resources. Geo-spatial technology is very useful to study about the groundwater in detail. In the present study delineate the possible groundwater potential zones in the Salem district using geo-spatial technology. The thematic layers considered in this present study, which are geomorphology, drainage density, lineament density. These thematic layers are integrated for identify the groundwater potential zone. Therefore, five different groundwater potential zones were identified, which are very good, good, moderate, poor and very poor. Finally, it concluded that the Geo-spatial technology is very efficient and useful for the identification of groundwater potential zones.

We analyzed the different pysico-chemical parameters during premonsoon season in the year 2013 to 2014. The analyzed physic – chemical parameters are Fluoride, Iron, Chloride, Nitrate, Sulphate, pH, TDS, Hardness and Alkalinity. All the parameters are coming under the desirable limit of drinking water except TDS. Two panchayats are having above the permissible limits of Hardness.

The methodology explains the precise study of the application of remote sensing and GIS. The climate, bedrock and time span are the main reason for the geomorphologic changes. The changes were noticed in the study area. During the 18 year gap the denutaional- dissected hills and valleys, dissected upper plateau, water bodies, structural – dissected hills and valley areas are decreased. The pediment and pediplain and anthropogenic origin areas are increased.

In this study proposes a 2014 land use land cover assessment of the study area. Based on land use land cover classification, the study area contains a seven type of classes. The Seven classes are Deciduous Forests, Build up/Mine area, Agriculture/ crop land areas, Evergreen and Semi evergreen forests, Cultivation and Plantation, Barren Land and Water bodies are occupying areas of 27%,18%,18%, 16%,15%, 6%, 0.4% respectively. Classified image was carried into accuracy assessment. The accuracy assessment gives a result of overall accuracy - 90%, Kappa Accuracy - 88%, Producer Accuracy - 90% and User Accuracy - 91%.
