Karachi is the most industrially developed and populous city of Pakistan. A big part of its basin is occupied by alluvial of Malir River, which is basically a seasonal river but becomes perennial within the limits of Karachi due to the continuous flow of untreated sewage and industrial effluents through its basin into the Arabian Sea. The data obtained during this study shows that the most down stream parts of the river are grossly polluted due to the inclusion of sewage and industrial wastes. Present data shows that pollution has not only deteriorated the pristine conditions of this river but it is also causing pollution in Arabian Sea where river finally falls. The data shows increasing trend of nutrients concentration and turbidity from 1994 to 1996. This study provides the base line data and reflects the quality of water in Malir river in middle 1990's. This data can be used to study the extent of pollution in Malir River by comparing it t o the recent data (if available) on Malir river.
