Water is very important for survival of all form of life on the earth. At present various types of organic and inorganic pollutants emerged out from solid wastes are discharged into the fresh water bodies. Therefore, quality of the fresh water is severely affected. The present investigation was planned to access water quality of Thamiraparani river stretch near Kuzhithurai, Kappucadu, Thangapattinam at Kanyakumari district. Water sampling was done from January, 2021 to December, 2021 to study the impact of solid waste dumping in the vicinity of the river at selective locations such as Kuzhithurai (Station I), Kappucadu (Station II) and Thangapattinam (Station III). The quality of the water was accessed in terms of physico-chemical parameters. All the selected parameters such as pH 8.35, turbidity (NTU) 14.5, conductivity 1262.25μS/cm3, alkalinity 507.5 mg/l, total hardness 550.5 mg/l, total dissolved solids 1274.25 mg/l, chlorides 447 mg/l, BOD 375.75 mg/l and COD 472.5 mg/l were maximum at station I when compared to the other stations. This result reveals that water could be unfit for drinking purpose.
