The present investigation deals with the analysis of water quality of Chalakudy river near Kerala Chemicals and Proteins Ltd. (KCPL) at Kathikudam, Thrissur district, Kerala. Water samples were collected monthly for a period of six months from March to August 2007 at 3 sites of Chalakudy River. Low dissolved oxygen, high values of conductivity, total hardness, biochemical oxygen demand, turbidity, nitrate and phosphate show unhealthy condition of the river. The conductivity, turbidity and pH of the water samples were not within the permissible limit in the site near KCPL during the period of study.
