Assessment of some physico chemical and microbial parameters of the water bodies of three rivers (Cauvery, Bhavani and Noyyal) which is suitable for human consumption have been carried out during the period of one year (September 2007 to August 2008). Analysis of some physico-chemical characteristics like water temperature, colour, electrical conductivity, transparency, total suspended solids, total dissolved solids, pÇ, dissolved oxygen, BOD, total alkalinity; total hardness has been done during the investigation period. Increases in temperature, turbidity, electrical conductivity, total solids, PH, bicarbonate, COD values were higher in Noyyal river followed by Cauvery river. The increase dissolved oxygen; BOD values were higher in Bhavani river. Study indicates the rivers were largely pollution by anthropogenic performance due to industrial effluents, municipal sewage, religious credence and subject to amend owed to seasons, climate and flows and influx of waters from various tributaries. In addition present study point out that the river Noyyal facing severe anthropogenic followed by Cauvery and Bhavani.
