We use water not only for drinking purposes but also for bathing, heating, agriculture, fishing, cooling and industrial processes. In Pakistan water quality is deteriorating day by day due to increase in population, and improper disposal of industrial waste water. Industries play a vital role in the socio-economic developmentofan area. Industries also have some adverse impacts on the human and physical environment in creating pollution problems due to mismanagement and lack ofpreplanning. The untreated industrial effluents of Hayat Abad Industrial Estate (HIE) find their way to fresh water bodies of NWFP. Due to adverse effects caused by water pollution, therefore it is essential to give greater consideration to know the magnitude and strength of pollution in industrial waste water. The present study was designed to characterize industrial effluents from HIE, to investigate the pollution load of these effluents and possible impacts on the surrounding area. Before collection of samples, a comprehensive industrial and field survey ofthe entire stretch of the main effluent drain up to the receiving water body (Shah Alam River) was conducted for the selection of sample sites and to identify the source and extent of pollutants. To obtain information about the degree of contamination caused by industrial effluents, samples were collected from forty sites. These sample sites included the drains of individual industries in HIE, Combined drains, sub drains, main effluent drain at various location, sewage and Nullah joining main effluent drain, (Confluence points) ,Nullah and the receiving water bodies i.e. Shah Alam River at Nakoba village and ultimately main Kabul River at camp Koroona (Akbarpura).To characterize pollution load, all the samples were analyzed for nineteen (19) water quality parameters; (seven physical, six chemical, one biological and five heavy metals). The analytical work was carried out in the laboratory by using the standard methods for the examination of water and waste water. The analyze parameter included flow rate, P", conductivity, temperature and Dissolved Oxygen (DO) were detected on the spot, while further analytical work was done immediately in the laboratory.enThesis
