Introduction: Pure water is an acceptable one for persistent health. The superficial view on drinking water does not give much idea about the presence of minerals in it. Analyzing the physicochemical properties of groundwater samples helps in determining the constituents present in them as well as identifying quality standards. For this study, drinking water samples were collected from fifteen bore wells in and around the industrial area of Cuddalore old town. The Physico-chemical properties such as Potential of Hydrogen (pH), Electrical Conductivity (EC), Total Hardness (TH), Total Dissolved Solids (TDS), Total Alkalinity (TA), Calcium (Ca), Magnesium (Mg), Sodium (Na), Potassium (K), Chloride (Cl-) and Sulphate ( SO42-) are studied and then compared with the standard values of World Health Organization (WHO). Pure water does not have any conducting property. The drinking water may have a high value of Electrical Conductivity due to the presence of elements and salts which are not at the standard level. Objectives: The acquisition of knowledge about the correlation matrix reveals the interrelation between any two parameters. Using this, the relationship between electrical conductivity and all other parameters is analyzed in this present study. The regression equation is formed to calculate the impact of individual parameters on electrical conductivity. Method: Statistical analysis helped to calculate the effect of each parameter on the high value of contamination in the groundwater due to electrical conductivity. Result: It is found that the presence of cations is highest in the order Sodium, Calcium, Potassium, Magnesium and the abundance of anions is highest in the order Sulphate and Chloride. Conclusion: The effect of each parameter on electrical conductivity has been studied. It showed that the percentage of TDS and Sodium was the maximum responsible for electrical conductivity. This study may be helpful to determine the quantity of each parameter that affects the quality of the groundwater and also used to evaluate the percentage of constituents present in it.
