Hydro-chemical Grouping of Ground Water in Coastal Region of Cuddalore District, Tamil Nadu Using Cluster Analysis

K. Manikandan, S. Natarajan and R. Sivasamy    

Abstract: Hydro-chemical ground water data of coastal region of Cuddalore district was subjected to cluster analysis to group the ground water based on its homogeneity and to find out the influencing factor on ground water quality. The twenty-seven water samples were collected during summer and post monsoon season of 2007 and characterized for nine physico-chemical parameters. These physicochemical parameters were subjected to cluster analysis. From the analysis, four and five distinct clusters were identified in summer and post monsoon season respectively. The different cluster recognized in the cluster analysis differed in chemical composition. It also had significant correlation with spatial distance from the sea as well as landform.
