摘要：The environmental quality is greatly focused on water because of its importance in maintaining the human health and health of the ecosystem. Many parts of the world are facing water scarcity problem due to limitation of water resources coincided with increasing population. Rivers are vital freshwater systems that are critical for the sustenance of life. In the present study, river water samples were collected in the period between January March 2012 from different parts of western Tamil Nadu, India and various physico-chemical and microbial analyses were performed based on standard methods. The comparative results showed the pH (7.5 to 10.0), DO (8-16 mg/ml), BOD (2.5 -7.5 mg/L), COD (14.5 -15 mg/L), total hardness (100-520 mg/L), calcium (80-200 mg/L), magnesium (20-320 mg/L), number of bacterial colonies(100-120 CFU) and number of fungal colonies(30-45 CFU).
