Introduction Water is known to be a universal solvent and this means that various substances can get added to water and remain completely or partially dissolved or at times even undissolved. Water pollution is a result of changes in its quality and such changes can occur due to natural reasons or as a consequence of one or more activities by humans Goel 1. Such changes in quality can render water unsuitable for consumption and also for any other domestic or agricultural purposes. Causes of Water Pollution Water can be polluted by various factors which can be physical, chemical or even biological Goel 2.
Introduction to water pollution essay industrialization is playing havoc with the environment. Industrial wasters, smoke and other gases are polluting the air in a big way.
Apart from industries, the density of traffic is also contributing to air pollution. The permissible limits of noise pollution have been exceeded in the cities of Kolkata, Delhi and Mumbai.
Air pollution is responsible for respiratory ailments, T. Proliferation of chemical industries has accentuated the problem. River waters have been polluted largely because of discharge of untreated industrial wastes and municipal sullage and drainage of pesticides and fertilizers.
All these have adversely affected their self-purifying mechanism by destroying their natural aquatic species. Exhaust from automobiles is a significant source of air pollution.
A large number of vehicles emit three to four per cent of carbon monoxide which is dangerous to health. Increase of chemicals in the atmosphere causes acid rains hundreds of miles away. These rains damage the soil, destroy vegetation and aquatic species in river and sea.
They also corrode buildings. The thin layer of ozone in the atmosphere is a form of life-sustaining system. It cuts out ultra-violet rays and allows the heat generating infrared rays to reach the earth. But due to industrialization and consequent pollution, the rate of depletion of the ozone layer is large.
Marine pollution is yet another problem caused by the discharge of sewage and harbor waste in coastal waters. Oil pollution arises from tanker accidents, refinery efluents and oil pipelines.
This results in the destruction of marine life and poses a threat to our eco-system. Nuclear pollution threatens life more than any other pollution today. Accidents can happen in nuclear plants and when these happen, these can be catastrophic for large sections of the people.
Nuclear radiation endangers the entire life-support system — plants, vegetation, animals, water, air and human health. Apart from all these pollutions, a serious threat to the globe arises from the pollution of outer space.
Space debris has become a reality on account of the litter and garbage of thousands of space objects, dead satellites, spent rockets, motors and nuts and bolts. The release of gases by rockets has adverse effects.
Re-entry of large objects into the atmosphere may also effect radio communication. Thus the ultimate victim of every kind of pollution, directly or indirectly, is man himself. Humanity today stands puzzled. A disaster threatens mankind in the near future. In just a hundred years, air may become unfit for breathing while water may become unfit for human consumption.
Scientists today are busy finding out ways and means to fight this terrible hazard of pollution but they have not so far succeeded in their mission. In the recent past, the Supreme Court of India has taken note of increasing pollution in the country.
In several judgments announced by the Court, it has directed the people to see that as far as possible pollution of air water is avoided.
Vehicles of all types have been required to conform to certain fixed norms in the matter of the gases being added by these to the air. Similarly factories and other commercial units have also been asked to stick to the anti-pollution norms laid down by the government.
Local bodies have been asked to use better hygienic conditions. All these steps are likely to go a long way in fighting out of menace of pollution but a lot remains to be done.Water pollution can be classified into point source pollution and non-point source pollution.
Point Source Pollution According to Kifferstein (), point sources are specific locations from which water pollutants are discharged through pipes, ditches into river. Fideisms Judaism is the Semitic monotheistic fideist religion based on the Old Testament's ( BCE) rules for the worship of Yahweh by his chosen people, the children of Abraham's son Isaac (c BCE)..
Zoroastrianism is the Persian monotheistic fideist religion founded by Zarathustra (cc BCE) and which teaches that good must be chosen over evil in order to achieve salvation. EPA Ireland: Water pollution: A longer, 7-minute introduction describing how Ireland's Environmental Protection Agency (EPA) is trying to tackle water pollution.
Although filmed in Ireland, the issues are general and apply to most other countries. Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light.
Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring heartoftexashop.comion is often classed as point source or nonpoint source pollution.

The contamination of air, water, or soil by substances that are harmful to living organisms. Pollution can occur naturally, for example through volcanic eruptions, or as the result of human activities, such as the spilling of oil or disposal of industrial waste. ♦ Light from cities and towns at night that interferes with astronomical observations is known as light pollution.
