River Water Pollution

As the population grows and the uncontrolled industrialization, urbanization rises as well, it is high time we should give proper attention to the fact of river pollution in our country which is deploying harmful impacts both on human health and environmental, aquatic ecosystem. A plethora of studies have been done on different aspects of river water pollution. In this paper a thorough discussion regarding this fact has been presented compiling a number of important studies on it. Major causes behind this pollution have been mentioned widely, like improper management of industrial and sewage effluents. However, to detect this contamination in the major rivers of Bangladesh, various studies have been done to see the physicochemical properties of the water, such as pH, turbidity, color, odor, DO, TOD, COD, TSS, EC, dissolved metal, and other chemical and bacteriological substances etc. The microorganisms within the water are the prime sources to cause different water borne diseases like Diarrhea, Cholera, Scabies and Asthma. To find out the remedies to this problem, urgent emphasis should be given on preventive measures and to take appropriate steps to halt and improve the existing pollution of the rivers. A lot of water treatment systems are being practiced throughout the world to restore the health of the rivers as well as to reuse the waste water. Though the systems are not much popular in Bangladesh, the government should facilitates the practice of them extensively and strengthen the laws against environmental pollution.

Water Borne

Fresh water is an essential amenity to survive. However, every year many people are directly or indirectly either dying or suffering from water-borne diseases. The main purpose of this study is to make a clear view of the pollution which is happening in Char Chanpara and how frequently the residents of that area are getting affected due to excessive pollution. Shitalakhya River and its surrounding area are suffering due to water pollution every year and now the situation is becoming worse. The polluted water from the river is infecting men, women and children in every possible way. Water is the most essential requirement to perform household chores, which are done by women and hence they are more prone to diseases caused by polluted water. Because of the poor economic status, they have no other option rather than using this water for their day to day activities. Proper initiatives by the government, awareness among people, disseminating news of this polluted river, constructing deep tube wells and availability of alternative uses of water are measured by which people can be saved from problems being caused by polluted water. This study aims to identify the causes of water pollution and how the residents of the area are affected by various types of water-borne diseases through their daily usages.

River Water Pollution

The research work is devoted to the analysis of the highest values of nutrient concentrations in the runoff in the Velikaya River for the period 1969–2009. According to the results of the study, when assessing the numerical characteristics of river water pollution, it is necessary to exclude outliers from the observation series. The presence of outliers in the calculation together with the main observational data leads to a significant overestimation of the numerical characteristics of river pollution in the average annual and multi-year period. In this case, it is necessary to study the characteristics of the outliers themselves, regardless of the initial samples. The paper presents an attempt to define the probability of outliers by combining outliers information on individual observation series.

River Water Pollution

This study was conducted to evaluate the Kapotaksha River water pollution status and its impacts on Human health and Environment. This study conducted a case study on four selected areas (Barakpur, Srirampur, Prbazar, and Gouranandapur) on the Kapotaksha river bank at Jhikargas Upazila. This river water pollution occurs by some natural process such as flood, storm, and natural biodegraded. But human activities are major reasons for the river water pollution. Industrialization, urbanization, domestic waste, sewage system, agrochemicals, etc are major causes for river water pollution. This more polluted water has an impact on human health and environment. This study was conducted to find out the polluted water due to various types of diseases such as scabies, asthma, dysentery and respiratory disease. Most of the people (49%) are affected by Scabies, 4% are affected by diarrhea, 5% are affected by dysentery, 25% of people are suffering from respiratory diseases and 4% are suffering from asthma and the polluted water pollutes soil by using the water in agriculture purpose answered by 20% respondents which is 100% of farmer respondents. If someone does not use this water can not affect soil answered by 80% of respondents. This river water becomes more polluted and harmful for human health and environment because this water hampered by the local colony, local trader, lack of proper management of sewage system, miss-use on the riverbank area for the dumping various solid waste on the river bank, chemical fertilizers, industries etc. At present now we cannot fulfill control this continuous river water pollution but we can minimize this problem and it would be positive for human health, others living organisms and Environment.
