The present research is concerned with the evaluation of water quality of the Narmada River. Water samples throughout its stretch right from origin point at Amarkantak to Badwani covering 10 sampling stations with 34 sub-sites of Narmada was sampled for water quality. The physiochemical parameters such as pH(8.38),EC(356 μS cm-1),TDS(252.8mg-1), Alkalinity(157.8mgl-1 as CaCO3),Chloride(58.7 mgl-1), Total Hardness (161.9 as CaCO3 mg l-1), D.O (4.7 mg l-1), B.O.D (2.4 mg l-1 for 5 days at 20 ºC), and nitrate (1.8 mg-NO3 L-1) were within the permissible limits as prescribed by the regulatory agencies. The interpreted comprehensive pollution index was 0.05-0.11; indicating that the river is clean.
