For this study, physico-chemical parameters such as pH, Colour, Electrical Conductance (EC),Total Alkalinity (TA), Total Hardness (TH), Calcium, Magnesium, Sodium, Copper, Lead, Manganese, Fluoride (F-), Chloride (Cl-), Silica, Sulphate (SO4-2), Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS) and Sodium Adsorption Ratio (SAR)were determined. The results were compared with the Indian standard. Correlation coefficient ‘r’, Regression analysis and Water Quality Index (WQI) were determined for monitoring water quality.
