Correlation study to predict water quality for drinking purpose

The present study on river Pandu was carried out to assess water quality indicators and correlation between physico-chemical parameters. The study clearly revealed that river is polluted to a considerable extent all through its entire stretch passing through Kanpur. High values of pollution indicating parameters noticed in the present study. The severely polluted stretch lies between stations 2 & 4 and to a considerable distance further downstream of station 4. Water at none of the stations is fit to be used as a source of potable water in the light of mandatory values recommended by I.S.I (IS;2296,1982). Association analysis established strong positive correlation between temperature, pH, total solids phosphate and sulphate. Total algal species established positive relation with DO and negative with COD.
