In this research paper physico-chemical characteristics of Harmu River at Ranchi were studied. The parameters studied were p H, Electrical conductivity, Total dissloved solids, Total suspended soilds, Total hardness, Calcium hardness, Magnesium hardness, Alkalinity, C hloride and Dissolved oxygen. The values of these parameters were found in excessive amounts as prescribed by World Health Organisation (WHO). It can be concluded that the water parameters which were taken for the present study are above the pollution level for surface water which does not satisfy their requirement for the use of various purposes. A brief attempt has been made to study the extent of change in the quality of water in comparison to water quality standards of World Health Organisation (WHO).
