Assessment on the characteristics of river kodayar with reference to Physico-chemical parameters

The physico-chemical parameters of water samples of Kodayar River collected across few stations were assessed.The parameters like temperature (T), electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), total hardness (TH), total alkalinity (TA), Sodium (Na), Potassium (K), Chloride (Cl), Nitrate (NO 3 -), Phosphate (PO 4 3-) and Sulphate (SO 4 2-) was determined.The results were compared with standards prescribed by WHO (1973) and ISI (10500-91).It was found that the water samples were not much contaminated and fit for domestic purposes.Few parameters in some of the selected stations were found to be higher and preventive measures should be adopted for quality water for domestic utilization.
