Groundwater has now become a vital source of water for domestic and agricultural activities all over the world. The objective of the present study aims to investigate the groundwater quality of Kosasthalaiyar river basin Tiruvallur district, Tamil Nadu. As a part of the study, 20 groundwater samples were collected for which the in-situ physicochemical parameters were analysed such as pH, EC, TDS and temperature was analysed. The study region underline by archaean crystaline rocks and sedimentary rocks. Geomorphologically most of the study region is covered by alluvial plain and pediplain. Groundwater level was measured for all the 20 wells. Groundwater level was fluctuated from 3 to 8m from surface. Most of the groundwater samples were alkaline nature. The EC ranges from 700 to 2,400 μS/cm. The present study shows that 95% of the sample falls within BIS (2012) permissible limit of TDS which may be employed for consuming without the risk
