Seasonal Variations in Physico-Chemical Parameters of Uppanar River Water, Cuddalore District, Tamil Nadu, India

The present study was determination of physico-chemical variations of water in 11 stations along the Uppanar River, Cuddalore district of Tamil Nadu, India. Physico - chemical variable in water samples collected along Uppanar River during summer and winter is analyzed for Temperature (t), Electrical conductivity (Ec), pH, Calcium, Magnesium, Sodium, Potassium, Chloride, Sulphate and Nutrients like Nitrate, and Phosphates. The noted increase of temperature and Ec is found in summer, whereas other parameters are more during winter. The study infers that the effluent flow, sewage drainage, catchment runoff and the tides are having great influence on the changes in physico-chemical parameters and fluctuation macronutrient. The degradation of our river ecosystem and water quality of various rivers all over the country is evaluated to understand the present status of Uppanar River.
