Abstract: Parboiled rice is one of the most popular rice produts. The process of parboiling involves soaking, steaming and drying and this production requires large amount of water for soaking the paddy. The soak water contains large quantity of organic material and when discharge large quantities of soak water repeatedly over a localised area where it stagnates and putrifies causing pollution of water and groundwater. This study will mainly focus on the effect of rice mills on groundwater at Okkal and Periyar river near Okkal. The groundwater present in the study area are polluted due to release of waste water from rice mills. To find out the extent of pollution, various water quality parameters such as Alkalinty, Iron, Hardness, Chloride, Acidity, BOD, COD, Dissolved Oxygen and Sulphate were studied. It has been found that the parameters such as Iron, Dissolved Oxygen, BOD and COD are not in the acceptable limit in accordance with the IS 10500 drinking Water Quality Standards.
