The tap water we receive can no longer be used for drinking, and we are forced to buy separate drinking water, install water purifying devices in our homes.

Have you wondered why we are forced to go in for such applications at our homes. There is no answer for water scarcity in big cities today and people are forced to live with the bitter truth. Water pollution is nothing but contamination of water bodies with chemicals, toxins and effluents let out from industrial establishments and factories. These toxins contain harmful concentrations of lead, Sulphur, heavy metals and detergents in them.

Not just that, water bodies are mixed with sewage water and one can imagine the extent of dirt and filth that is contained in the waters of river bodies, thus making them highly polluted. Pollution is tainting or forcefully mixing harmful and toxic substances into environment. These substances that endanger the consistency and integrity of the environment are called Pollutants. The environment has been enduring the abuse we afflicted on it since ages. The daily activities that we perform, also pollute the earth due to inefficiency of the methods we use.

Alarming quantities of pollutants are being produced and released. Speaking about water, most of the industries and factories have leftover chemical effluents.

They release these residual products into primary water sources like rivers streams, lakes, fresh water tanks etc. The microbes present in the natural sources of water have the ability to purify the water to some extent.

But the problem arises when we dump more Pollutants before the current batch of water is purified. Microbes present in water have the natural ability to oxidize it. But constant human intended interference has almost nullified that ability. The activities of the microbes in cleaning up the water reduce to a low minimum or may not take place at all.

Waste water from domestic sources is also often dumped into rivers. This pollutes the entire source. Water pollution affects us on a daily basis.

The cases of water borne disease are on the rise. Since water is one of the building blocks of life, we have but no choice to consume the same water in adequacy. The dangers of polluted water increases when people unknowingly use polluted water for daily purposes. Factories set up near river bodies may be releasing effluents and people downstream maybe using the same water for drinking purposes and for other daily activities.

It is common knowledge that 70 percent of the earth is covered by water. But not all of this water can be used for drinking and household purposes. Only a small percentage is fresh water, and most of the other share in the percentage finds itself frozen at the Poles. The advent of pollution has further reduced the potable water resources. Water available today is way more polluted than it was ages ago. Our quality of life is greatly affected by this. Use of polluted water causes diseases and ailments.

It can be directly linked to the receding length of our lifespan. Water pollution is a global problem and one that does not respect national boundaries. Sources of pollution may be domestic, agricultural or industrial. In less-developed countries, human and animal waste and sediments from unsound agricultural and forestry practices are the main pollutants.

In more-developed countries; industrial pollutants, such as toxic metals, organic Chemicals and heat add to the water pollution problem. The effectiveness of treating wastes prior to their release into the environment determines the balance between potential and actual pollution. The release of large quantities of oxygen-demanding organic waste into watercourses often has disastrous effects on the indigenous flora and fauna.

The primary source of organic waste released into fresh waters is sewage effluent. Other sources include run-off from urban areas and farms, and some industrial effluents. The recent intensification of livestock production, with larger herds concentrated in smaller areas, has exacerbated the problem of organic pollution from farm animal wastes.

Aquatic primary productivity is often limited by the availability of inorganic plant nutrients. In freshwater lakes and rivers, the limiting nutrient element is usually phosphorus, whilst in marine waters nitrogen is often in short supply.

If small amounts of nutrients enter aquatic ecosystems where they are normally limiting, primary productivity is stimulated. The water body becomes over-enriched by excessive nutrient input and consequently polluted. Both acid rain and acid mine drainage contribute significantly to the acidification of natural waters. These two phenomena are dealt with in detail in this section. However, there are other causes of this particular type of water pollution.

For example, the planting of extensive tracts of coniferous forests, usually in upland areas, results in the acidification of the soil and the waters which drain these plantations. Organochlorines are, as name suggests, organic compounds containing chlorine. Manufactured organochlorines include a number of pesticides, for example DDT, and polychlorinated biphenyls, or PCBs as they are known. These two groups will be considered separately, although they do share a number of important characteristics.

For example, both groups are reported to have endocrine-disrupting properties. In , the first organochlorine pesticide, DDT dichloro-diphenyl-trichloro-ethane was manufactured for the Allied Forces to be used during the Second World War. It met with unprecedented success against a number of insect-borne diseases, for example malaria in the tropics and typhus in Italy. It had many advantages; it was cheap to manufacture, persistent in the environment and could be applied from the air.

The success of DDT resulted in the development and manufacture of other organochlorine pesticides, for example lindane and dieldrin. Drilling for oils is one of the major extractive industries. Crude oil is a complex mixture of thousands of different organic molecules, mainly hydrocarbons aromatics, alkenes and cyclohexanes. It is refined by the process of fractional distillation to yield a number of commercially important products such as petrol, diesel oil and tar.

From these different types of oil, seas and rivers are being polluted regularly. Sometime accidental spillage from oil tankers causes drastic damage to the environment through oil pollution.

Water pollution is one of the world's worst forms of pollution. For example, take a look at a glass of water. It may appear clear, but there are really millions of microscopic pollutants floating in it. Approximately 70% of the earth's surface are covered by water; water is a very dynamic system 3/5(10).

Privacy FAQs

Pollution itself is when a substance or energy is introduced into the soil, air, or water in a concentrate. Pollution comes in many forms; agricultural, urban runoff, industrial, sedimentary, animal wastes, and leeching from landfills/septic systems just to name a few.

Essay on Water Pollution Water covers two-thirds of the Earth’s surface, with over 97% present in the oceans and less than 1% in freshwater streams and lakes. Water is also present in the atmosphere in solid form in the polar icecaps and as groundwater in aquifers (water-bearing rocks) deep underground. Article shared by. Essay on Water Pollution! Water pollution may be defined as deterioration of physi­cal, chemical and biological characteristics of water through natural and anthropogenic activities to such an extent that it becomes harmful to human beings, plants and animal communities.
