The ground water is an essential and valuable source of water supply all over the world. To meet the rising demand it is decisive and recognizes the fresh water resources to find out remedial methods for improvement of water quality the present study aims in determining the ground water quality in and around the coastal area. Water quality index (WQI) of groundwater based on the data of nine groundwater samples collected from coastal area of Sirkali block in Nagapattinam District, Tamilnadu was assessed using seven physio-chemical parameters viz. pH, Total Dissolved Solids, Total Hardness, Calcium, Chloride, Magnesium and Electrical conductivity. The WQI value 379 is maximum and the value 57 is minimum during pre-monsoon period and 224 is maximum and 29 is minimum value achieved during post-monsoon period in the study area. The computed WQI shows that 0% of groundwater sample fall in the ‘excellent’ water category during both monsoon periods and moreover maximum groundwater samples falls on category unfit for drinking purposes, indicating that the groundwater is not suitable for direct consumption and require treatment. After treatment, the water can be used for drinking purpose.
