Abstract

The present investigation is an attempt to study the effect of sewage discharge into river Ganges and to record the qualitative change in water. Water samples were collected from Kanpur
sampling station on the Ganga river within Kanpur city in the year 2012 (April) -2013 (March)
and analyzed for 14 water quality variables (physico- chemical) parameters, the data obtained
were standardized and subjected to principal components analysis (PCA) to define the
parameters responsible for the main variability in water quality variance for Ganga River within Kanpur city. Results reveal that total dissolved solids, total alkalinity, total hardness were the parameters that are most important in assessing variations of water quality in October, November, December, January, February, March, April (post monsoon season) in the river. Results also reveal turbidity, suspended solid were the parameters that are most important in assessing variations of water quality in June, July , August and September in the river (monsoon season). This study suggests that PCA technique is useful tool for identification of important river water quality monitoring months and parameters. Ca+2, Cl-
, SO4-2, temperature, Flouride, pH, Fe, Oxygen consumption (O.C), Cl-, Mg+2 are found to be non principal water quality parameters.
