Wastewater samples were collected from Hayatabad Industrial Estate, Peshawar and investigated for physical and chemical parameters. pH was in the range of 6.2 to 7.6, magnesium was 0.456-10.523mg/L, Copper was 1.035 to 10.230 mg/L, lead was 1.023-6.52 mg/L, manganese was 0.231- 9.852 mg/L, zinc was 0.231-12.34 mg/L, cadmium was 0.120-8.523 mg/L, cobalt was 0.214 – 4.562mg/L, silicon 0.321 – 14.52 mg/L, nickel was 0.231-12.3 mg/L, iron was 0.231-11.23 mg/L, and chromium was 0.123-6.321 mg/L. The values were compared with the standards of NEQS and it was found that some of the parameters show deviations due to the direct disposal of effluents into the environment and may affect life when they enter the water bodies. Therefore the effluents must be treated before they enter the environment.
