Water quality Assessment Of The Turag River

Abstract

The Turag River system is in the southern part of the north central region of Bangladesh, passing through west and south of Dhaka, the capital of Bangladesh. The river receives wastewater from numerous numbers of sources along its way, which are discharged as industrial effluents, municipal sewage, household wastes, clinical wastes, and oils. The purpose of this study is to investigate the impact of this wastewater on the river water and thus to provide an updated report on the state of water quality of the river Turag. The water samples were collected During the year 2024 from different points along the river and analyzed for various physiochemical quality parameters, directly into the river or into drains and canals which The Turag River having a length of 72 km is been reports that the river is being polluted by located in the southern part of the North Central Region discharge of industrial effluents, municipal wastewaters, of Bangladesh, close to the confluence of the turag household wastes, clinical and pathological wastes, oils (Ganges) and Upper Balu Rivers. It is tide-influenced and human excreta. In recent years, the river has become river passing through west and south of Dhaka City, then dumping ground of all kinds of solid, liquid and capital of Bangladesh the average flow of the chemical wastes which are generated by the activities in river varies between 140 cubic meters/sec in dry season and around the river. (November to May) and 700 cubic meters/sec in wet the largest share of pollution load into the river season (June to October) The average depth and Turag appears to be from about width of the river is 13.5 m and 82 m respectively. Industries in the Tangi and Ashulia area many people and industries depend on (nearly 10,000 people rely directly on this industrial the Turag River for various social and economic cluster for their source of income). Studies show that up purposes. The major land use along the banks of the river to 15,000 cubic meters of liquid wastes, 19,000 kilograms is for residential and commercial purposes, e.g. bazaars of solid wastes and 17,600 kilograms of Bio logical Oxygen (markets), industries, warehouses, and hospitals. Many Demands load go into the Turag each day from people who live along the river use the river water for these industries Moreover, previous studies swimming, washing, bathing, and boating (both for identified that each day 3,500 cubic meters of wastes from recreation and communication).
