Appraisal of river water quality based on field observations: A case study on narmada river

Abstract

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 (252.8 mg l-1), Alkalinity (157.8 mg l-1as CaCO3), Chloride (58.7 mg l-1), Total Hardness (161.9 as CaCO3mg l-1), D.O (4.7 mg l-1), B.O.D (2.4 mg l-1for 5 days at 20 °C), and nitrate (1.8 mg-NO3L-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. © 2020 Ecological Society of India. All rights reserved.
