The aim of the present work is to find the quality of water in and around the Nagapattinam region and geochemical study of water and its chemical composition with qualitative and quantitatively assessed from the period of post monsoon ( January) in the year 2020. Therefore, ten underground water sample were taken from different areas in Nagapattinam region and analysed for the following qualities such as Color, odour, temperature, Electrical conductivity, total dissolved solid, Hydrogen ion Concentration, calcium, magnesium, chloride, potassium, sodium, nitrate, and sulphate and trace metals like manganese, lead, chromium, copper, iron, arsenic, cadmium and zinc. The physico chemical parameters indicate the quality of ground water varies from bore well to bore well. Higher values of any parameter in a borehole indicate that the water is not fit for drinking. Therefore, the public is advised that the groundwater source in the study area should be monitored before it is used for domestic and drinking water purposes and that the government should adopt some treatment technology in the current study regions to minimize the hardness and salinity for provide safe water to the public.
