This paper intends to assess the water quality with reference to drinking, agriculture and industrial uses in the ground water in Alangudi Taluk, Pudukkottai District. In this taluk has been evaluated by considering 50 water samples collected from bore wells. In this sampling was carried out using pre- cleaned polyethylene containers, this sampling analyzed the data collected from the Public Works Department (PWD), Ground Water Division (GWD), Thiruchirapalli, Tamilnadu, for the year 2010. The physical and chemical parameters of the analytical results of groundwater were compared with the standard guideline values recommended by the World Health Organization for drinking and Public Health Standard. Thematic map preparing to TDS, EC, Cl, NO3, SO4, and Na were maps was developed Using Arc GIS-9.3 platform. The data were used to compute chemical parameters as non-carbonate hardness, sodium absorption ration percentage of sodium, residual sodium carbonate, magnesium ratio, chloro alkaline index found to be used on evaluation of the chemical parameters quality of water is fit for drinking, industrial and agricultural uses, accept in a few isolated locations. According to Wilcox’s diagram indicates that less then 95 percent of samples fall in excellent to good and good to permissible types. According to the USSL diagram based on most of the samples fall in the field of C2-S2 indicating same salinity and sodium water, which can be used for almost all types of soil with no danger of sodium. Majority of the samples are suitable for domestic purposes and far from drinking water standards.
