Wastewater samples li'om ten industries of Hayatabad Industrial Estate were collected and investigated for the physical and chemical parameters. The findings. of the research show that; temperature of the samples at the spot was 26-42°C, while temperature in the lab. was 17-40oC, pH was 6.63-13.09, electrical conductivity was in the range 0.20-3.13 mS, T. S was 0.76-14.35 mg/L, T. D. S was 0.40-6.63mg/L, S. S was 0.01-7.73mg/L, total hardness was 210-1400 mg/L, alkalinity as CaC03 was 100-1413 mg/L, chloride was 86580mg/L, sulphate was in the range 120-794 mg/L, sulphite was 2.83-47.08mg/L, nitrate was 0.5-11.6 mg/L, phosphate was 2.25-16 mg/L and fluoride was 0-11.0 mg/L. The values were compared with the standards and it was observed that, some of the parameters show deviations from the standards and may affect the life. Therefore the et1luents must be processed before entering into the environment.
