River Water Pollution in Buriganga on the Context of Bangladesh

2013

When water becomes contaminated by unexpected substances, it is considered as harmful for human and aquatic lives. This water is termed as polluted water. Various causes are responsible for polluting water. Some natural causes are mixture of biodegraded portion of animal and plants to pure water, siltation by erosion of river banks etc. Domestic wastes, industrial wastes, fertilizers etc. are man-made pollutants of water. The state of surface and ground water pollution in Bangladesh is alarming. Especially the Buriganga is largely polluted by Dhaka city. Necessity of water for each and every living beings needs no description. They intake water directly or indirectly for physiological activities. If this in taking water is polluted, it will do harm that is for sure. The worst part is, this bad impact transports to others through food chain. Therefore, we must be aware of the adverse influence polluted water may have on us. At present, we cannot prevent water being polluted cent percent, but minimization is very much needed. It is time we took some steps to start working on it.

Abstract: When water becomes contaminated by unexpected substances, it is considered as harmful for human and aquatic lives. This water is termed as polluted water. Various causes are responsible for polluting water. Some natural causes are mixture of biodegraded portion of animal and plants to pure water, siltation by erosion of river banks etc. Domestic wastes, industrial wastes, fertilizers etc. are man-made pollutants of water. The state of sur-face and ground water pollution in Bangladesh is alarming. Especially the Buriganga is largely polluted by Dhaka city. Necessity of water for each and every living beings needs no description. They intake water directly or indirectly for physiological activities. If this in taking water is polluted, it will do harm that is for sure. The worst part is, this bad impact transports to others through food chain. Therefore, we must be aware of the adverse influence polluted water may have on us. At present, we cannot prevent water being pollute...

The study was conducted in the Department of Botany, Govt. Titumir College, Dhaka, Under National University, Bangladesh with the objectives to prepare a Research term paper with a view to partial fulfillment of the requirements for the degree of Bachelor of Science (B.Sc.) in Botany. The specific objectives of the study were to study the surrounding environment at some selected locations around Buriganga River, to assess the river water quality parameters, to investigate the reasons behind this extreme water pollution and finally to provide some suggestions to improve the existing condition. The Buriganga River is the life line of Dhaka city and flanked in its southern side. It provides important services to the residents, including water supply, navigation, recreation, and sanitation and flood control. The vital river however has become extremely polluted and is close to biological death for several reasons. The main objectives of the study are overview the causes of pollution, the water quality and sources of pollutants of Buriganga river and formulate some recommendation how save the Buriganga River. To complete the research work I choose secondary data analysis as the tools. The Buriganga River has dramatically been disrupted due to extreme reduction of its water flow and encroachment of the banks and rigorous pollution due to human waste, industrial garbage and solid waste dumping. Thus Buriganga poses serious environmental threats to the Dhaka city’s sustainable environment. The Buriganga River is now highly polluted and becoming more or less dead due to dumping clinical, industrial and household wastes, industrial effluents, and discharge of oil from river vehicles. The water quality of the Buriganga river drop his standard level due to tannery effluents, human waste, sediment, pathogens. Due to the severe pollution and loss of normal flow of water, the Buriganga River effects on the environment, social and economical impacts of the surrounding area. Unfortunately there is no strong monitoring to save Buriganga river. This report recommends promoting a sustainable environment in the Dhaka city area and healthier life for its inhabitants. It is essential to save the surrounding river system especially the Buriganga river.

Buriganga river is used for bathing, drinking, irrigation and industrial purposes and is considered to be the lifeline of Dhaka city. The water quality of Buriganga has become a matter of concern due to serious levels of pollution. The objective of the study was to determine the water quality of the selected section of Buriganga river which passes through Dhaka city. The water quality parameters were sampled during different seasons (summer, winter and autumn) and in 10 different sampling points along the river along the banks of the Buriganga River. The water quality parameters studied for this study were dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH, turbidity, conductivity, total dissolved solids (TDS), nitrate and phosphate. The results showed that DO, BOD, COD, TDS, turbidity, nitrate and phosphate are at an alarming level and a discussion on the possible sources of the pollution are presented.

This study deals with evaluating the surrounding environment at some selected locations (Hazaribagh, Mitford Ghat, Sadarghat and Postogola) around Buriganga River, to evaluate the river’s water quality in terms of some very fundamental water quality parameters (such as pH, temperature, alkalinity, turbidity, iron, chloride and BOD). To do this assessment for the Buriganga River, the study area was chosen to find out the water quality parameters such as the pH of water of river Buriganga was shown a variation from 7.4 to 6.8. The right bank of the river holds higher pH value from the left bank and middle. The colour of the river water was shown a variation from 322 to 756 mg/l. The turbidity of the river water was shown in a variation of 7.2 NTU to 55 NTU. The chloride of water of the river Buriganga was found in a range of 55 mg/l to 178 mg/l. Alkalinity of water of the river Buriganga was found to vary from 370 mg/l to 471 mg/l. Among them 370 mg/l was shown in Hazaribagh and 471 m...

Dhaka was established as a provincial capital of the Mughal ruler on the northeastern bank of the Buriganga River during 1608-10. This river has enormous significance to the residents of Dhaka. Not only it surrounds the city, but also it provides important services to the residents including water supply, navigation, recreation, sanitation, fish production, tourism, biodiversity and flood control. A study was carried out to observe the ecological health hazards and their risk to human health of the Buriganga River. The samples were analyzed to determine water quality. The study showed that the water is high in biological oxygen demand (BOD), chemical oxygen demand (COD), Electrical conductivity (EC), Total dissolved solid (TDS), Salinity, Alkalinity, Turbidity and low in dissolved oxygen (DO) which revealed huge environmental health risks and possible ecological disruption of this river.

them contributes more to the destruction of the environment. With the current trend of population growth followed by the construction of companies to suit their wants, such a situation may worsen. Hazardous gases, dust particles, or liquid effluents are the waste products emitted from industrial sources. These discharges are full of harmful chemicals that pollute aquatic ecosystems, disrupt the local biota, and eventually harm living things and associated flora and animals. As a result, studies were conducted, including the physicochemical characterization of sugar refineries, distilleries, and other rivers that receive such effluents. These characteristics of subsurface water were also taken into consideration throughout the inquiry. This research will be anticipated to offer proper preventive methods for preserving the purity of the Bangladeshi rivers.
