PHYSICO-CHEMICAL PARAMETERS OF ITHIKKARA RIVER, KERALA, INDIA
Ithikkara river was comparatively unpolluted rivers of the Kerala State, without any major industry in its bank. The present study was carried out to evaluate the water quality scenario of the Ithikkara river. Seasonal and annual average values of surface and bottom water temperature, pH, dissolved oxygen, free carbon dioxide, salinity, nitrate, nitrite, phosphate and silicate, and averages of transparency and velocity of flow were observed from six different stations are presented in this paper. Observations revealed that physico-chemical characteristics were almost at the optimum level..
