ABSTRACT

Seasonal monitoring of the physico-chemical parameters and microbial population of the Hogenakkal river water was done to assess the water quality. The obtained values of different physico-chemical parameters and correlation co-efficient of microbial population revealed both positive and negative correlation at 0.01 and 0.05 level of significant. Evaluation of multiple regressions and multiple linear regression analysis were predicted from the available data and the quality of water was determined on the basis of environmental conditions, physico- chemical parameters and anthropogenic activities. The present investigation reveals that the water quality of the Hogenakkal River was not highly deteriorated with respect to the physico-chemical parameters. However, fungal population was found exceptionally high (24x103CFUml-1) during pre-monsoon when compared to the bacterial population (20x103CFUml-1) in monsoon season.
