Short Paragraph Water Pollution - Important India, short essay on water pollution in english5/20/2017 Hazardous pollutants may contain various types of impurities including harmful chemicals, dissolved gases, suspended matters, dissolved minerals, and even microbes. All the contaminants reduce the level of dissolved oxygen in the water and affecting the lives of animals and human beings to a great extent. Dissolved oxygen is the oxygen present in water required by the aquatic system to continue the lives of plants and animals. However biochemical oxygen is the demanded oxygen by the aerobic micro-organisms to oxidize organic matters of wastes. Water pollution is caused by two means, one is natural water pollution (due to the leaching of rocks, decay of organic matters, decay of dead matters, silting, soil erosion, etc) and another one is man-made water pollution (due to the deforestation, set up of industries near large water bodies, high level emission of industrial wastes, domestic sewage, synthetic chemicals, radio-active wastes, fertilizers, insecticides, pesticides etc). There are many sources of the water pollution (point source and nonpoint or diffused source) depending on the specificity of waste materials discharged from various sources. Point sources includes pipelines, ditches, sewers, etc from industries, sewage treatment plants, landfills, hazardous waste sites, leakage from oil storage tanks which discharges wastes directly into the water bodies. Diffused sources of the water pollution are agricultural fields, live-stock feed lots, parking lot and streets into surface water, storm runoff from urban streets, etc which pours their discharged pollutants over the larger areas water bodies. Non-point source pollution contributes highly to the water pollution which is very difficult and expensive to control. Water pollution is the most dangerous and worst form of pollution putting lives in danger. The water we drink daily looks very clear however contains verities of microscopic pollutants floating in it. Our earth is covered with water (almost 70% of total) so a little change in it could affect lives worldwide. When we drink the polluted water, harmful chemicals and other pollutants goes inside our body and deteriorates all the body organs functioning and puts our lives in danger. Such harmful chemicals also disturb the lives of animals and plants greatly. When plants absorb dirty water through their roots, they stop growing and die. Thousands of seabirds are killing because of the oil spilling from ships and industries. High level of water pollution is done due to the chemicals coming out of the agricultural usage of fertilizers, insecticides and pesticides. The effect of water pollution varies from place to place upon the type and amount of water contamination. The degradation of drinking water needs an urgent basis prevention method which is possible by the proper understanding and support from the end of each and every person living on the earth. The highest level of water pollution is caused by the pollutants come from agriculture field because of the high use of fertilizers, insecticides, and pesticides to enhance the production of crops. We need to bring vast improvements in the type of chemicals we use in the agriculture. Oil is another big pollutant polluting the water. Leaked oil from the land or rivers, oil transport through ships, ship crashes, etc flows to the sea or ocean and affecting whole water. Other hydrocarbon particles get settled down through rain water from air to ocean or sea water. Other toxic wastes through leakage of landfills, old mines, dumps, sewage, industrial wastes, and farms get mixed to the water. The sources, effects, and control measures of Water Pollution are discussed below.
