Water is a critical source used all around the world to keep our way of life flowing. The use of water goes from regular house needs to creating energy in many ways. Around the world drinkable water starting to run low and the water stored is being contaminated by pollutants causing sickness and death. Countries are going through droughts which affects the water supply needed to maintain irrigation, and public supply. Water pollution is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment.
Millions of people have faced with living-and-death issue due to constant use of contaminated water. Polluted water source causes the deleterious impact on the community. The common consequence is the rising rate of people at higher risk of acute and chronic diseases relating to water pollution such as dermatitis, digestive diseases, diarrhea, and cancer has risen. In several regions, patients diagnosed with cancer, gynecologic infections account for 40-50% of cases, due to polluted water sources. Polluted water and poor sanitation claim the lives of about 9,000 people per year in Vietnam, according to the Ministry of Health and the Ministry of Agriculture and Rural Development.
WATER POLLUTION IN ELURU CANAL – VIJAYAWADA Introduction: Water pollution is referred to the contamination of water bodies such as lakes, ponds, canals, rivers, oceans and ground water etc by physical and chemical substances. This occurs when pollutants are directly or indirectly discharged into the water. It leads to environmental degradation effecting the plants and organisms living in the water bodies. Water pollution may also occur from natural causes such as sedimentation, volcanoes, storms, floods, earthquakes etc. Though earth is covered by 70% of water, hardly 2% is the drinkable water.
Water Pollution is the addition of harmful chemicals to natural water. Sources of water pollution in the United States include industrial waste, runoff from fields treated with chemical fertilizers, and run-off from areas that have been mined. (Dictionary.com).The issue of water pollution has a long history around the world. Water Pollution is one of the leading causes of death in Africa and some parts of Asia. For some, such as Africans and Americans, the issue of water pollution has a particular significance to those who are poverty-stricken.Recently the case of Flint, Michigan has drawn attention to the subject of water pollution.
Among environmental problems, pollution of rivers obtained highest percentage (87 %) for 'very important option '. Air pollution, poor drinking water supply, noise pollution and damage to countryside also were very important for most of the respondents.  only about 18 percent thought it is bath able and less than one percent told us it is drinkable, . More than 97 percent of respondents thought having the river in the city is useful; only less than 3 percent told us it is useless
The polluted water can damage the nervous system, liver, DNA and kidney. A type of pollution is soil pollution which causes cancers including leukemia etc. The presence of lead in soil is hazardous for young children and can damage to the brain. The high level of Hg can increase the risk of kidney damage and causes neuromuscular blockage.It also causes skin rashes,headaches,eye irritation,nausea and fatigue. The polluted air and water also affect animals such as acid rain destroys aquatic life in water bodies.We are observing a regular increment in the temperature and express the concern for global warming.
Water pollution is when there is a build of one or more substances in water to such an extent that it causes problems for animals or plants. This form of pollution has increased as the population of this town has increased. There are two different ways in which water pollution can occur: • If pollution occurs from a single location such as a discharge pipe attached to a factory it is known as point-source pollution. • A great deal of pollution happens not from one source but from many different scattered sources. This is known as nonpoint-source pollution.
When contamination raises the water temperature it sometimes forces fish and other organisms to relocate. Contamination in the water is highly dangerous for the lives depending in these water bodies; it harms the organisms and can disrupt food chains. Water pollution threatens aquatic life and increases the amount of air pollution by
WATER POLLUTION INTRODUCTION It is called ‘Pollution’, “when something is added to the environment that makes it unclean or unsafe” (C.Dozier, 2001,p1). According to Arvind Kumat, (2008,p.142) “Water pollution is defined as the addition of some substance (organic, inorganic, biological, and radiological) or factor (e.g. heat) which degrades the quality of water so that it either become a health hazard or unfit to use. Water pollution not only affects plants and organisms living in the bodies of water, but it also damages the natural biological communities. (Dingra and Singh,2004) Over 70% of the Earth’s surface is covered by water but less than 1% of it is available for drinking and agriculture; thus making water pollution a very significant issue.
