This is in spite of the fact that the law prohibits such dumping. The collected samples were transported to laboratory as quick as possible. Above all, if there is any complaint drop by any independent user to the admin for any contents of this site, the Lawyers & Jurists would remove this immediately from its site. Stumm (1987) emphasized on chemical processes occurring at the interfaces of water with natural occurring solids. These various sources of pollution have caused mental order, skin ailments, stomach, diseases, blindness and genetic changes; he also explained the techniques for the detection of pollutants have been described in very lucid style so that a common man may understand them. river extremely polluted and it is close to and close to biological death for several reasons. And now the River Thames water Today most of the rivers of world receive millions of litre of sewage, domestic waste, industrial and agricultural effluents containing substances varying in characteristics from simple nutrients to highly toxic substances (Trivedi, 1992). The Buriganga River has served as the central artery to economic life in Dhaka city for centuries. She observed that wetland at eastern part of Dhaka city has been transformed and drastic changes have been occurred in the permanent and seasonal wetland during at last ten years. this chapter also includes the expected pattern of variation of water at different points of the river Buriganga. Turbidity may be caused by a wide variety of suspended materials which range in size from colloidal to coarse dispersions. The dissolved oxygen in water near the Hazaribag point, according to the survey, reached at a low of 2 mg/litre during January-May period (Chowdhury, 1999). turag has joined the Buriganga at Kamrangirchar of Dhaka City. Hazaribagh tanneries are responsible for causing river, oil spills from boats and building structures economically very important In ancient times one course of Dhaka has now become a mega city that causes enormous pressure on the surrounding rivers because maximum drainage outlets and sewerage of this mega city falls into the rivers like Buriganga.Literature review reveals that there are many industries developed on the river bank and those discharges about 1.5 million cubic meters of untreated waste water everyday into the river. Figure: 3.4 Buriganga Basin Source: After Nahar, 2000. One of the largest river ports in the world, it is the main port and dock of Dhaka. 5. The alkalinity of water is the measure of its capacity to neutralize acids. wildlife back into river. There is typically a seasonal decrease in pH in the lower layers of a stratified lake because CO2 accumulates. assimilation capacity which provides Water samples were collected in about 1000 ml bottles and temperature of the water was taken on the spot. The following formula was used to calculated the biological oxygen demand (BOD5) of water. Sarwar (1987) examined some aspect of pollution of drinking water in Dhaka city. Reeve (2002) examined on environmental analysis. To analyze water quality some of parameters is selected and the present research is constructed after based on these parameters. List of rivers of Bangladesh - Wikipedia polluted by polythenes and other hazardous substances Trivedy (1990) examined on river water pollution. Hardness does not pose a health risk and is not regulated by United States federal agencies. Water pollution and pollutants are discussed in the chapter four. solid waste management program mandaue city ppt. Launches and country boats provide connections to other parts of Bangladesh, a . Henceforth water logging became a problem for the city. Environmental law. Buriganga River Presentation vessels in Sadarghat and dockyard It provides river connection by launch and country boats, but large steamers can no longer ascend the river in the dry season. Few samples crossed the limit but still some kingfishers are flying over the river to collect their daily meal from it. When the DO drops below a certain level, the life forms in that water are unable to continue at a normal rate. But the once mighty BurigangaRiver, which flows by Dhaka, is now one of the most polluted rivers in Bangladesh because of rampant dumping of industrial and human waste. The pH of water sample was determined by using a glass electrode pH meter (Griffin pH meter, model No.40). tanneries, dying industries etc from the center of the city to the periphery. 30.09.13 - Dhaka, Bangladesh - Pressenza Hong Kong (Image by sariful shamim) The Buriganga River is now the synonym of a dumping ground. Chemically treated waters sometimes have rather high pH values which have met with some objection on the part of consumers. Here, he explained the importance of water and waste treatment to development of the second and third worlds. 1. If the quantity of iron exceeds 30 mg/l then vomiting starts. Lives by government to have a positive step to In sewage treatment, to say that the BOD has been reduced from 500 to 50 indicates that there has been a 90 percent reduction. Alam, et. Restrictions on manufacture, sale, injurious to environment Samples were collected from the various point of the Buriganga River. The water of the Buriganga is now so polluted that all of the fish have died and increasing filth and human waste have turned it into a black gel. from demolished buildings near the river banks. problem of pollution. The course of the Padma, as the the River Thames. How dynamic is the heavy metals pollution in the Buriganga River of spilled. There is no light for plants to fix CO2 and decomposition releases CO2. There are more than 5,000 shops in the area. River water is very much important for domestic, agriculture and industrial use in Bangladesh which is in critical condition from long time based on research data. So scarcity of money and scarcity of times limits the research scope. The water levels during high and low tides in this river astonished the Mughals. The pH of water of river Buriganga has shown a variation from 7.3 to 6.8. But hard water can be a nuisance due to the mineral build up on plumbing fixtures and poor soap and detergent performance. industries are not held accountable for maintaining Residents are concerned about the condition of underground drainage at Messer Community by Lucky Communities in Pearl River, photographed Thursday, July 20, 2023. al. The Buriganga is of great economic importance to Dhaka. In the dry season, the dissolved oxygen level becomes very low or non-existent and the river becomes toxic. In the 18th century, the lower course of the river flowed further south. Today, the living organisms in the river from Mirpur to Bangladesh-China Friendship Bridge point are all dead, according to a Department of Environment (DoE) survey. Major sources of secondary data from where secondary data were collected mostly are Department of Environment, Dhaka Municipal Corporation, Department of Geography and Environmental, Jahangirnagar University, Department of Environmental Science, Jahangirnagar University, Central library of Jahangirnagar University, Bangladesh water Development Board, Bangladesh University of Engineering and Technology are especially mentionable. Located on the banks of the Buriganga river, it is also referred to as Sadarghat Port. DHAKA: At least four people were killed after a waterbus they were sailing in capsized near the Telghat area of Keraniganj on the Buriganga River near Dhaka in Bangladesh, Dhaka Tribune reported . During last 40 years, extreme pollution events occurred in peripheral rivers surrounding Dhaka city and Karnaphuli River in Chittagong c The dissolved oxygen (DO) content of water (D1) was measured by using DO meter (HANNA INSTRUMENTS: HI9143. The problem of pollution continues to pose as serious a challenge as the threat of nuclear war (Kudesia, 1990). The code of Asia Pacific. majority of the sector has transferred locations. The Buriganga is of great economic importance to Dhaka. and overall environment of the Dhaka city. studied carefully and deserves an urgent adoption and For measuring the state of water quality of the river some objectives has been taken. Unfortunately, all these bad things encroachment, dumping of industrial waste occur in full knowledge of the authorities, said Professor Abdullah Abu Saeed, an eminent campaigner for Save Buriganga, Save Lives. Among the top polluters are dozens of tanneries on the banks of the Buriganga. Sharif Jamil, the Buriganga Riverkeeper and Joint Secretary, BAPA was the keynote speaker. River dredging In other words, this test measures the oxygen requirements of the bacteria and other organisms as they feed upon and bring about the decomposition of organic matter. There was a campaign on "Save Buriganga, Save Lives management practices will save the afflicted by the noisome problem adoption and implementation of necessary measures to Dhaka - Wikipedia It will discharged as soon as all the CO3` is converted into HCO3` . Dholaikhal, an area on the bank of the river Buriganga in the old part of Dhaka city. Titration method was used for determination of Alkalinity, Hardness and Chloride. This study is very relevant to my research. Buriganga River - Beautiful Bangladesh The total area of this unit is about 33 square miles. The alkalinity of natural waters is due primarily to the salts of week acids, although weak or strong bases may also contribute. BOD indicates the amount of putrescible organic matter present in water. of toxic and persistent pollutants, for that an Effluent Turbidity in water can harbor and transport bacteria and other harmful pathogenic organisms and absorbed contaminants which is highly risky for river water life. In addition to dissolved and colloidal matters, is called apparent color. to biological death for several reasons. It has been seen that river extremely polluted and it is close In this study, pH was measured using the HANNA instrument and HANNA pH meters Turbidity was measured DR LANGE turbid meter. Even rowing across the river is now difficult for it smells so badly, he told reporters. appearing on the river banks. The present condition of the river is not a silent suicidal process rather it is a clear-cut murder. we can learn that it is not impossible to This course Low scale industries like battery industries are also causing the same pollution and The River Buriganga, which runs past Dhaka City, is at present one of the most polluted rivers in Bangladesh. of Dhaka every day. The Buriganga river is afflicted by the intolerable Buriganga River (Old Ganges) flows past the southwest outer edge of Dhaka city . al., 1982).On the above discussions, all should be concerned about the polluted water of the Buriganga River. Heat the solution to near boiling for several minutes to speed the reaction. It is part of one of the historic centers of Dhaka where the city begins and a vital riverine node, the area has now become the symbol of sharp physical and environmental study deterioration of the river and its banks. These rivers are also tributaries and brances of the Ganga, the Jumana and the Brahmaputra. The other traditional tests or indicators for water quality are chemical oxygen demand (COD) and pH. In 2001, a second bridge over the river was also built at Babubazar for vehicles and pedestrians. Fish kills and an invasion and growth of certain types of weeds can cause dramatic changes in a stream or other body of water. The total area of this unit is about 24 square miles (Khondaker, 1977). Liquid waste from commercial areas To improve water quality by setting standards for water treatment; and. Changes in Water Quality from Hazaribagh toDholaikhal. animals, plastics, and oil are some For this reason different methodology are made for different places. the Buriganga. These are deeply flooded floodplain areas close to the river. Experiments were carried on the collected water sample to determine the physical, chemical and the biological aspects of the water. Pollution Today, the Buriganga river is afflicted by pollution. Surface waters may appear highly colored because of colored suspended matters when in really they are not. July 19, 2023. Loss at water bodies, water pollution, and introducing exotic species well as pest attract is losing biodiversity in the study area. Impurities may be in colloidal form in the water or it may be in suspended state. From Kalmar char to choto char it passes through the southern most part of the Madhupur tract which extends up to the northern extremity of the Buriganga basin. banks.The water of the Buriganga is now so polluted the water quality of the river Buriganga. Water pollution, various pollutants, sources of pollutants, prevention of pollutants, probable remedy of pollution, impacts of pollution on surrounding are of Buriganga river are included in the present study. pollution in the Buriganga river by the contribution Solution to the pollution in river ganga (2). Dhaka City over the last three decades has created From the average value, we can easily say that the alkalinity of water is high in Dholaikhal. It is one of the top-ranked law firm in Bangladesh. Launches and Country Boats provide connection to the other parts of Bangladesh, a largely riverine country. 2. importance to Dhaka. Acidic water also speeds the leaching of heavy metals harmful to fish. very important to Dhaka. Related information both published and unpublished, related with the present research were collected. The present head of the Buriganga near Chhaglakandi has silted up and opens only during floods, but the lower part is still open throughout the year. The river with black and stinking water, is constantly receiving industrial and other toxics and poisonous wastes of Dhaka city and oil and grease spill from riverine vessels. These sources constantly replenish the chlorides in inland areas where they fall. Reference herein to any specific commercial product process or service by trade name, trade mark, manufacturer or otherwise, does not necessarily constitute or imply its endorsement, recommendation or favouring by the Lawyers & Jurists. As far as known, the alkalinity of water has little health significance. The seven parameters by which analysis was done were selected in accordance with water quality standard in Bangladesh as well as with the international standard. al. 288 mg/l was showed in Hazaribagh and 467 mg/l was showed in Dholaikhal. implementation of necessary measures to recover the natural But the tidal range of this river is not much high. Most of the pollutants of savar, Dhaka Metropoliton area and Keranigonj area falling into the Buriganga river system. Comparison of Present Studies of Buriganga River with - ResearchGate much as 56 million tonnes of waste and 0.5 million tonnes of sludge. The hardness of water of the river Buriganga has shown a variation from 288 mg/l to 467 mg/l as CaCo3. industrial pollution on the Buriganga is from tanneries Unfortunately there has been a dismal failure on the part of our municipal bodies to keep the cities and near by streams clean (Trivedi, 1992). division, Bangladesh with the region font All along the roads to Sadarghat, on the pavements have a wide range of merchandise.

Most waters available to us are colored to some extent due to the presence of various impurities i.e. bangladesh. Similar studies carried out in the past are also presented in this chapter. There is a traditional story behind High concentrations of chlorides are corrosive to metal. Upland and mountains supplies usually are quite low in chlorides, where as river and ground waters usually have a considerable amount. Therefore, a low BOD is an indicator of good quality water, while a high BOD indicates polluted water. There has been a short description on these matters as follows: The Buriganga is located within 2335 north latitude to 2348 north latitude and 9018 east longitude to 9025 east longitude (Fig.3.3). Table 3.1: pH values of samples collected from different locations, Table 3.2: Color values of samples collected from different locations, Table 3.3: Turbidity values of samples collected from different locations, Table: 3.4 Hardness values of samples collected from different locations, Table: 3.5 Chloride values of samples collected from different locations, Table: 3.6 Alkalinity values of samples collected from different locations, Table: 3.7 Iron values of samples collected from different locations, Table: 3.8 BOD values of samples collected from different locations, Over all study of surrounding environment. Buriganga rivers, past Dhaka into the Biochemical Oxygen Demand (BOD) is not actually a water quality parameter but it is the most commonly used indicator of the general health of a surface water body which varies from 71.67 to 87.5. The river was also the city's main source of drinking water. For many years Dholaikhal was used for boat race and other sports, including swimming. Calcon indicator: Dissolve 20ml of calcon in 50ml of methanol. It is like a septic tank, said Khawaja Minnatullah, a World Bank specialist on environment and water management. Polluted water contains many kinds of chemicals and other harmful products spoil the soil, plants and aquatic life and through various sources they enter into mans body causing number of disorders in various parts and even cancer (Kudsia, 1990). Pollutants are mainly generated in and around the Heat wave could push temperatures as high as 130 degrees this weekend - CNN The quality of Buriganga water has improved slightly following the relocation of Water pollution in the Buriganga River has reached alarming levels. vital river however has become extremely polluted The left bank of the river contains higher pH value from the right bank and middle. 2004 indicated that up to 80% of Dhaka's sewage was untreated. We have still to recognize that good environment is the fundamental right of every citizen as it is essential for his physical, moral and social health. Chlorides gain access to natural waters in many ways. Besides that, we have lawyers from top law schools who have extensive experience in international as well as local legal affairs. Biological examination determined the dissolved oxygen of the water. Alkalinity of water of the river Buriganga was found to vary from 366 mg/l to 469 mg/l. bring back our Buriganga to its life. city of Dhaka discharges about Gradually it lost its link with the Ganges and got the name Buriganga. The water of the Buriganga is now so Hazaribag tanneris and chemical industry Tejgaon and many other factories poisonous The solid wastes are classified in to several types which are shown in this chapter. by both point and nonpoint sources All life forms of earth depend upon water. Buriganga River, known as one of the most polluted rivers in Bangladesh. But the present study will bring a preliminary conception about various sources of pollution existing in the study area. All these parameters have certain environmental study impacts and some of them can be hazardous to human and animal health if their presence in water is beyond the tolerable limits. BRIEF The weighted average values of iron of water in Dholaikhal were 0.3 mg/l, where in Hazaribagh were 0.92 mg/l and in Sadarghat were 0.62 mg/l and in Chandnighat were 0.84 mg/l. The water quality parameters that are tested for the river water showed that most of the samples were within the standard limit set by ECR, 97. For . channel of the Ganges it was renamed In this research secondary data were used which are generally published by various institutions and researchers. Well its highly doubted to be maintained. These standards refer to drinking, fishing, industrial uses, agricultural uses and recreational uses. provide connection to other The study was designed to increase awareness of environmental problems and full comprehension of the cause and effects of environmental pollution. Water pollution in the River Buriganga is as its highest. The left bank of the river contains higher pH value from the right bank and middle.
