This study was designed to assess the physico-chemical characteristics of Cauvery river three stations
(S1- Domestic sewage release place, S2- Pooja waste release place and S3- People dress washing place.
Erode. The parameters were analysed such as Temperature, pH, Colour, Odour, Turbidity, DO2, BOD, COD, Salinity, Total
alkalinity and Total hardness. The pH ranged from (8.2 to 8.7), Dissolved oxygen (4.987 to 6.253mg/lit), BOD (13.768 to
17.564mg/lit), as recorded in S1 Place. COD (34.7 to 36.7mg/lit), Calcium (89 to 105mg/lit), Salinity (7.12 to 12.6mg/lit), as
observed in S2 place. Total Alkalinity (164 to 198mg/lit), Nitrate (0.32 to 0.45mg/lit) and Phosphate (0.34 to 0.40mg/lit) as
analyzed in S3 Place. The nding of the study revealed that the river water is polluted not advisable for human usage without
any treatment. This study concluded that the seriousness and responsibility of public to conserve our water resources for healthy
