Pollution Sources Assesment of Turag River, Bangladesh

Abstract

A study was carried out on Turag River with a view to observe and identify the present pollution sources of Turag river. Point and non-point sources of pollution of Turag River have been identified by several times of field visit during the the dry and wet periods of 2014 and 2015. From the field visits, it is clear that there are numerous illegal domestic sewage outfalls directly discharging waste into the river. In the Turag River many types of waste basically semisolid and liquid particles are being discharged every day. The water of the river is polluted mainly by industries, household waste through drainage, hospitals, shops, shopping malls, bazaar, storm water, mobiles or oils from many types of boats, launches etc. In order to decrease pollution from various sources appropriate steps can be taken to reduce the concentration of water quality parameter. Adoption of adequate measures to reduce the level of pollutants from the industrial wastewater and renovation of sewage treatment plants are suggested to avoid further deterioration of the river water quality. It is recommended to implement existing law and regulations, to remove illegal residential and industry building from the bank of river, to establish effluent treatment plant (ETP) etc. To ensure better accuracy, follow up study should be continued also to check the validity and consistency of the results.
