Long and Short Essay on Water Pollution in English

Under rather exceptional circumstances, water bodies may become significantly contaminated by the atmospheric deposition of pollutants. 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.

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. Humans have realized that they have greatly affected the environment in a bad way. Everywhere, efforts are being made to conserve water. Water treatment plants are setup everywhere.

Every waste disposal station has a water treatment department, so that all the chemical and other harmful substances can be removed from water before it is let into the main source.

This has been pivotal in controlling pollution of water. Rules and regulations have been made stringent for factories and industries, regarding their effluent emission, both through the air and through water.

Domestic waste disposal techniques have been improved and proper steps taken in the right direction. It is entirely up to us, what we decide to do, with our water sources.

Global warming is becoming an ever gaping issue and a worldwide concern. The everyday tasks that we do would become incredibly difficult. We need to take measures ourselves, to save water and keep it from being polluted.

We must start conserving water in our homes. Only then will the next generation have even the slightest hope for a well-rounded future. The first issue, the most common one as we know is of the contamination of water by toxins and measures to reduce the contamination and improve the quality of water. The second one is more serious and pertains to the availability of potable water on earth after some years, putting a question mark on the survival of life on earth itself.

We talk about beautifying our lakes, restoring the cleanliness of our water bodies, removing their contaminants and making them toxic free.

Yes, this is definitely required at the moment and there have been measures taken in the right direction to make our rivers clean and clear. This is primarily to remove hard traces of waste or what we can call as visible wastes.

This also takes removes unnecessary growth of phytoplankton in rivers, thus letting the river waters breathe at ease. Regarding toxin removal from river waters, purification using reverse osmosis methods, chemical filtration methods and other treatments using distillation methods are employed to make them free from chemical residues.

Much other advancement have been achieved and successfully employed in the river basins of our country to restore the natural beauty of lakes and rivers. The best example of river water cleaning in our country is the cleanliness drive carried out at river Ganga in the holy city of Varanasi. The government of India took it up as a big challenge to clean the river waters at the region and was successful in achieving its mission.

It is only with citizen co-operation and participation that any reformative measures taken by the governments will prove fruitful and worthy of action. We blame successive governments for not cleaning up our river beds, for not providing us clean drinking water, for not beautifying our lakes etc. If we visit rural areas and spot women washing their clothes, utensils and cattle in river waters, it is our duty to educate them and spread awareness about their wrong acts.

Instead of turning a blind eye against something wrong happening in front of us, we can reach out and provide help in our own small ways to set things right instead of just blaming and complaining about our authorities.

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).

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.

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. Water pollution, like other types of pollution result when an overwhelming amount of waste comes from different sources of pollutant which harmfully disrupts the balance of the ecosystem; consequently, the waste cannot be destroyed or cleaned up as quickly as produced which results in many disadvantageous to humans and animals, as well as .
