Seasonal variations of physico-chemical parametersof gangawater at ghazipur city, uttar pradesh, India

An assessment of the seasonal variations of the river water quality of GangaRiver at Ghazipur. ranges of the estimated physico-chemical parameters are mentioned as temperature (20.40C -31.90C), pH(7.3-8.86), TDS( 313mg/L -387mg/L), EC(297µmhos/cm -367µmhos/cm), Alkalinity( 175mg/L -327mg/L), TH (127mg/L -200mg/L), sulphate(16.2mg/L -37.2 mg/L), phosphate(0.41mg/L -0.96mg/L), nitrate(0.41mg/L -0.96mg/L), chloride (20.5mg/L -31.3mg/L), DO (5mg/L -6.5mg/L),BOD (5.3mg/L -15.2mg/L) and COD(11.2mg/L -30.1mg/L). EC, BOD and COD were above the USPHS and BIS standards at all the sites of Ghazipur. Correlation coefficient revealed varied positive and negative correlations in the physicochemical parameters of the river water.
