RIVER WATER QUALITY ASSESSMENT –A CASE STUDY

Abstract

The water quality assessment of the Yamuna River has been carried out to explore the status of the river water in terms of Water Quality Index (WQI). Eighteen water locations along the River Yamuna were checked for seven parameters and analysed for bacteriological and physio-chemical parameters. The parameters dealt are Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Ammonia, pH, Total Kjeldahl Nitrogen (TKN), Chemical Oxygen Demand (COD) and Faecal Coliform (FC). Three Indices namely National Sanitation Foundation Water Quality Index (NSFWQI), Canadian Council of Ministers of the Environment Water Quality Index (CCMEWQI) and Oregon Water Quality Index (OWQI) were used in this work to determine the quality of water in these locations. The results generally range between medium to bad water quality and in some few locations especially from Palla, Nizamuddin bridge going down to Udi the quality is almost unsatisfactory. So we can say that nowadays is difficult to have pure water which can simply be consumed without treatment.
