Document on water pollution

  1. 1. Water Pollution FactsThis article deals with water pollution facts that theworld must be made aware of. With sincere effortsdirected towards reducing water pollution, one canhope to have clean water resources for futuregenerations.A simple definition of water pollution can be presentedas "contamination of water which makes it unfit foruse". Most of the water resources on earth are polluted.Even though our planet is covered with 70% water, notall of it is suitable for human use. Rapidindustrialization, misuse of the scarce water resourcesand many other factors play a role in the process ofwater pollution. Every year around 400 billion tons ofwaste is generated the world over. Most of this waste isdumped in water bodies. Out of the total water on earthjust 3% is freshwater. If this freshwater is pollutedrepeatedly, water crisis would turn grave in the nearfuture. It is therefore, necessary to take proper care ofour water resources. The facts about water pollutionpresented in the article should help in understandingthe gravity of this problem. Let us understand moreabout water pollution through details presented below.RRNagar – I Care – A green initiative & community welfare group ofRajarajeshwarinagar

  3. 3. Water pollution is a problem that affects almost allnations of the world. If proper steps are not taken tocontrol this menace, it would lead to disastrousconsequences in the near future. The facts pertainingto water pollution are presented with the help offollowing points.Rivers in the continent of Asia are the most polluted.These rivers contain 20 times as much lead found inwater bodies of industrialized nations of othercontinents. The bacteria (from human waste) found inthese rivers are 3 times greater than that of the globalaverage.In Ireland, fertilizers and sewage are the mainpollutants of water. About 30% rivers in this countryhave these pollutants.Contamination of groundwater is a major problem inBangladesh. Arsenic is a major pollutant which affectswater quality in this country. About 85% of the totalarea of Bangladesh has contaminated groundwater. Itmeans, over 1.2 million citizens of this nation areexposed to the hazardous effects of arsenic-contaminated water.The King river in Australia is amongst the most pollutedrivers of the world. Around 1 million sea birds, 100,000marine mammals and several other creatures have beenRRNagar – I Care – A green initiative & community welfare group ofRajarajeshwarinagar

It is observed that around 40% rivers in the US are polluted. One cannot use water from these rivers for drinking, swimming or any such activity. These rivers are not capable of sustaining aquatic life. Forty-six percent of lakes in USA are unfit for supporting aquatic life. Pollutants released in water by the construction industry includes cement, gypsum, metals, abrasives, etc. These materials are far more harmful than biological wastes - which can at least be diluted easily. Thermal pollution of water is caused by disposal of hot water by industries. Rise in water temperature is a threat to the ecological balance. Many aquatic creatures lose their lives because of thermal pollution. Drainage caused by rain is one of the major causes of water pollution. Waste materials like oils, chemicals released from automobiles, household chemicals, etc. are the major pollutants from urban areas. Chemical fertilizers and remains of pesticides form the main pollutants that are drained by rain. Oil spills in oceans is one of the global problems responsible for water pollution on a large-scale.4
  5. 5. Thousands of fish and other aquatic creatures are killedby oil spills every year. Apart from oil, non-degradablewaste materials like plastic are also found in oceans.The article on ocean pollution facts should help gain agreater understanding of the subject matter.The process of eutrophication is one in which nutrientspresent in water bodies increase to a great extent. Thisleads to increase in the primary productivity of thatwater body. The result of eutrophication is excessivegrowth of phytoplankton. Level of oxygen in waterreduces to a great extent and thereby, the lives of fishand other water creatures come under threat.Controlling Water PollutionIt is necessary to understand that the water we pollutecan harm us in the long run. Once the toxic chemicalsenter the food chain, people have no option but, to livewith and carry them in body systems. Reducing the useof chemical fertilizers is one of the best ways to clearwater pollutants from our environment. Otherwise,these washed-out chemicals would continuously pollutethe water bodies on earth. Efforts are being made toalleviate the problem of water pollution. However, theproblem cant be solved completely; effective stepsneed to be taken for its mitigation. Considering thepace at which we are disturbing the ecosystem, it hasRRNagar – I Care – A green initiative & community welfare group ofRajarajeshwarinagar

Lakes and rivers of the planet earth are becoming increasingly polluted. Concentrated and organized efforts by people and governments of all nations of the world should help in minimizing the problem.6
