Water quality assessment of Chenab river and its tributaries in Jammu Kashmir (India) based on WQI

Abstract

An assessment of the water quality has been carried out to explore the water quality index (WQI) of Chenab river and its tributaries in Jammu Kashmir (India). Fourteen water samples from Chenab river and its tributaries at various locations were collected and analyzed for physico-chemical and bacteriological parameters. Nine parameters i.e. BOD, DO, fecal coliforms, nitrate, pH, temperature change, TDS, total phosphate and turbidity were considered for calculating the WQI based on National Sanitation Foundation (NSF) information system. The WQI showed good water quality, except Bichleri stream water indicating that water of Chenab river and its tributaries are least polluted and is suitable for drinking after conventional treatment. The WQI rating of Bichleri stream water is medium as it carries wastewater and may not be useful for domestic use without treatment.
