Ground water quality of the Karur Taluk was assessed to understand the contamination processes due to the presence of various contaminant sources and the suitability of ground water for drinking, agricultural, domestic and other purposes. Ground water samples were collected during 2017 at 12 different locations of Karur Taluk of Tamilnadu state of India. Their physico-chemical parameters like colour, odour, turbidity, TDS, EC, ph, TA, TH, Ca2  were assessed. The results were compared with the drinking water guidelines of Indian Standard (IS) and World Health Organization (WHO). The multivariate statistical studies of Descriptive analysis, Correlation co-efficient (r) analysis, Factor analysis and Cluster analysis were analyzed using SPSS (version 19.0) to determine the various types of pollution formation in the Karur Taluk.
