This work has been undertaken to investigate the wastewater samples from Kodagu industrial area namely (i) Treated trade effluent- industrial effluent (sample 1) and Nanjangud industrial area (ii) Treated combine effluent - the combination of drainage waste from household and effluent wastewater (sample 2) from industries. Both the samples were subjected for physical and chemical parameters such as pH, total suspended solids (TSS), chloride (Cl¯), ammonia, sulphate (SO₄²¯), BOD and COD. In sample 1 all the parameters are within permissible limit, so it is fit to release to the water bodies like lake, river and streams. In the sample 2 except for chloride content, all other parameters have been reported higher than permissible limit, sulphate being very high range of about 1550 mg/L. The higher values than permissible limit are due to high pollutants in the water. The organic and inorganic substances are present in high concentration than expected. Therefore sample 2 neither can be released to the water bodies nor can be used for gardening or flushing toilet tanks as it causes soil pollution or contamination of water bodies.
