Essay on water 200 words.

Water, known to be the universal solvent, plays a key role in the survival of various forms of life on earth. It is used for various purposes such as drinking, cleaning, cooking, washing and bathing. Besides these domestic uses, major amount of water is used in the agricultural sector mainly for the purpose of irrigation. A substantial amount of this substance is also used in the industrial sector.

However, unfortunately despite being aware about the importance of water in our lives, people around the world are leaving no stone unturned in wasting water and deteriorating its quality. The techniques used for irrigation in many parts of the world including India are old and mundane and often cause immense loss of water. Several industries make use of a good amount of water however they end up throwing their waste in water bodies without realizing that the deterioration of water will ultimately lead to their own loss.

Water is one such substance without which we cannot imagine our life. Besides, quenching our thirst, this transparent chemical substance is used for several other purposes. It is used to accomplish several household tasks. Water is also used for agricultural purpose and is needed for industrial use. Here is a brief look at how it is used at different places.

Agricultural Use

It accounts for around 70% of the water used around the world. In agriculture, water is mainly used for the purpose of irrigation. In addition to this, it is also used for the raring of the livestock. Most of the water used for irrigation is extracted from rivers. Groundwater is also used for this purpose.

Rivers are thus said to be of great importance for the farmers. Not only do they provide water for irrigation but they also play a vital part in the water cycle.

Industrial Use

Industrial use of water includes water used for the purpose of washing, diluting, cooling, transporting, fabricating, manufacturing and processing of various products. Thermal power plants, engineering and pulp and paper industries are among the one that consume the maximum amount of water.

Domestic Use

At home water is used for many purposes. This mainly includes drinking, cooking, bathing, washing utensils, washing clothes, cleaning houses, cars and other vehicles, watering plants and for the purpose of sanitation.

Also Check: World Water Day

Each country has its own system of water supply to ensure water reaches every household so that the aforementioned basic needs of its citizens are met.

Water is vital for the survival of the mankind. However, unfortunately it is being wasted at a rapid speed around the world. Everyone should contribute his/her bit towards saving water.

Essay on Water 400 Words

Water is derived from various sources. Rivers, lakes, seas, oceans and rain are known to be some of the main sources of water. This free flowing and readily available colourless, odourless substance is needed for domestic, agricultural as well as industrial use.

Sources of Water

The sources of water are mainly divided into two categories – Surface Water and Ground Water. Rain water pours and collects on earth in the form of surface water as well as ground water. Here is a brief look at both these sources of water:

Surface Water : It is found in rivers, lakes, reservoirs, streams, seas and other such sources. The water in lakes and rivers comes from rain and the melting of snow. The river water flows into the sea.
Ground Water : It is found under the land. Water travels under the surface of the land by way of soil on the non-porous rocks and fills the opening in these rocks. The rocks that store and send out groundwater are known as aquifers. At times, the water stored in these rocks bursts in the form of springs due to high pressure. Ground water is also extracted by digging wells and tube wells.

Water Available for Human Use

Our planet is rich in water with around three-fourth of its surface being covered with water. However, only a small part (just about 2.7%) of the total resources of water is available for the human use.

Around 97.3% of water on earth forms a part of the oceans. It is salty and cannot be used for the purpose of irrigation or any other agricultural use. It is not even good for industrial or domestic use. Out of the 2.7% fresh water available on earth, the inland surface water that is the water available from sources such as rivers, lakes and ponds accounts for just about 0.02%. This water is crucial for the growth and survival of all forms of terrestrial and freshwater aquatic beings.

It is thus important to use it wisely. This point is emphasized time and again. However, its criticality is not yet recognized by the people. It is essential to understand the importance of saving water else we will have to learn it the hard way.

Many areas around the world get sufficient water supply. However, several others, especially those that are a part of the developing countries, face water deficit. The government of such countries must ensure proper supply of water to various areas and the people must use water wisely and avoid any kind of wastage to ensure the flow.

Essay on Water 500 Words

Water (chemical formula H 2 O) is a transparent chemical substance. It is one of the basic necessities for every living being be it plants or animals. Just as air, sunlight and food, water is needed for the proper growth and development of life on earth. Besides quenching our thirst, water is used for numerous other activities such as cleaning, washing and cooking to name a few.

Properties of Water

Water is mainly known for five of its properties. Here is a brief about these properties:

Cohesion and Adhesion

Cohesion, also referred to as water’s attraction to other water molecules, is one of the main properties of water. It is the polarity of water by way of which it is attracted to other water molecules. The hydrogen bonds present in water hold the water molecules together.

Adhesion is basically water’s attraction between molecules of varied substances. This substance bonds with any molecule it can form hydrogen bonds with.

Lower Density of Ice

The hydrogen bonds of water turn into ice when cooled down. The hydrogen bonds are stable and maintain their crystal like shape. The solid form of water which is ice is comparatively less dense as its hydrogen bonds are spaced out.

Water’s High Polarity

Water has high level of polarity. It is known to be a polar molecule. It is attracted to other polar molecules and ions. It can make hydrogen bonds and is thus a powerful solvent.

Water’s High-Specific Heat

Water can moderate temperature owing to its high specific heat. It takes a long time when it comes to heating up. It holds its temperature for long when heat is not applied.

Water’s High Heat of Evaporation

This is another property of water that renders it the ability to moderate temperature. As the water evaporates off a surface it leaves a cooling effect on the same.

Avoid Wastage of Water

Water is required for most of the activities we indulge in our day-to-day life. It is necessary for us to conserve it else our planet will be devoid of fresh water in the years to come. Here are a few ways in which water can be conserved:

Fix leaking taps immediately to avoid wastage of water without any delay.
Avoid the use of shower while bathing.
Keep your tap off while brushing your teeth. Turn it on only when required.
Wash full loads of laundry instead of half. This will not only save water but save a substantial amount of electricity too.
Do not leave the water running while washing dishes.
Use rainwater harvesting system.
Avoid using water hose for cleaning gutters. You can use brooms or other techniques instead.
Use the right size of pans and other dishes while cooking and eating food. Avoid using those bigger than your requirement.
Try to water your plants by hand rather than using sprinklers.
Cover the pools so as to avoid water loss due to evaporation.

We must not waste water and contribute our bit towards its conservation. We must practice and promote activities and plans that help in conserving water and protecting its sources to meet the current and future demands of living beings.

Essay on Water 600 Words

Water is the most common liquid found on our planet. It is vital for the survival of every living being. Around 71.4% of Earth is covered with water. However, while most part of our planet is covered with water, fresh water that can actually be used for drinking, cooking and other activities is quite less. It is thus important to use this substance wisely.

Different Forms of Water

Water is present in three different forms on Earth – Solid, Liquid and Gas. Here is a brief look at these forms:

Solid : Water freezes at 0 degree to form ice which is its solid state. As water freezes, its molecules move apart and this makes ice less dense compared to water in its liquid state. This means that ice is lighter than the same volume of water in its liquid state. It can thus float on water.

Liquid : This is the most common form of water. Water in its liquid state is used in several ways including drinking, washing, cleaning, cooking, irrigating fields and processing and preparing various products in industries.

Gas : As water boils, it changes from liquid to gas, often referred to as water vapour. Vapours are always present around us. When the water vapours cool, they form a cloud.

What is Water Cycle?

Water cycle is the term given to the circulation of water on, below or above the Earth’s surface. It is the process wherein water circulates between land, oceans and atmosphere. This involves precipitation, snowfall, drainage in rivers, lakes and streams and its return to atmosphere by way of evaporation and transpiration. Water cycle is also referred to as hydrological cycle.

Water Scarcity in India

Like most of the other developing countries, many parts of India also face scarcity of water. People in the country do not get clean water for drinking and there is water deficit for the purpose of sanitization as well. None of the cities in the country receives piped water 24/ 7. It is supplied for just a few hours each day mostly for a couple of hours in the morning and an hour or two in the evening. The quality of water has deteriorated in most of the water bodies in the country. This is because of the discharge of industrial and domestic waste in water.

The scarcity of fresh water in the country is often attributed to lack of proper planning at the government’s end, corruption, increased rate of corporate privatization and increasing amount of human and industrial waste that is discarded into water. The situation is expected to worsen in the times to come as the population of the country is likely to increase to 1.6 billion by 2050.

Here is a look at some of the other causes of water scarcity in India:

Traditional techniques of irrigation employed in our country cause a lot of water loss.
Lack of proper planning and distribution of water among domestic consumers, agricultural sector and industrial sector.
Decline in traditional water recharging areas.
Urban development has choked the ground water resources.
Increasing number of recreational activities associated with water.

While water is available on earth in abundance, it needs to be understood that the amount that can be put to use for various domestic, agricultural and industrial use is limited. It is essential to use it wisely so as to ensure it reaches every one and is also available in abundance for our coming generations. The government must employ effective techniques to save water and distribute it evenly in various areas across the country. The general public on the other hand must use it wisely to ensure that it is not wasted.

Water Pollution Essay

Water Pollution and How it Harms the Environment

Global pollution is a problem. Pollution can spread to remote areas where no one lives, despite the fact that urban areas are typically more polluted than the countryside. Air pollution, water pollution, and land pollution are the three main categories of pollution. Some contaminated water has a terrible smell, a muddy appearance, and floating trash. Some contaminated water appears clean, but it contains dangerous substances that you can't see or smell.

Together, developed and developing nations must fight to conserve the environment for present and future generations. Today, we dig deep into the subject of Water Pollution. This article can be an introduction to water pollution for kids as we will read many things such as the causes of water pollution further in the article.

What is Water Pollution?

Water contamination occurs when pollutants pollute water sources and make the water unfit for use in drinking, cooking, cleaning, swimming, and other activities. Chemicals, garbage, bacteria, and parasites are examples of pollutants. Water is eventually damaged by all types of pollution. Lakes and oceans become contaminated by air pollution. Land contamination may contaminate an underground stream, a river, and ultimately the ocean. As a result, trash thrown on an empty lot can eventually contaminate a water source.

(Image will be uploaded soon)

Water Pollution

The water cycle, called the hydrological cycle, involves the following steps:

Evaporation- Because of the sun's heat, the water bodies such as oceans, lakes, seas etc., get heated up, and water evaporates in the air, forming water vapours.

Transpiration- Like evaporation, the plants and trees also lose water from them which goes to the atmosphere. This process is called transpiration.

Condensation- As the water evaporates, it starts to become cool because of the cold atmosphere in the air and because of this cooling down of water leads to the formation of clouds.

Precipitation- Because of the high movements of the wings, the clouds start to collide and then fall back to the earth’s surface in the form of rain. Sometimes they also fall back in the form of snow, hail, sleet etc., depending upon the temperature.

Runoff or Infiltration- After precipitation, the water either flows to the water bodies called runoff or is absorbed into the soil, called infiltration.

Causes of Water Pollution

There are many reasons for water pollution. Some of the reasons are directly affected by water pollution and some indirectly. Many factories and industries are dumping contaminated water, chemicals, and heavy metals into major waterways as a result of direct water pollution.

One more reason for water pollution is the use of modern techniques in farms. Farmers apply nutrients such as phosphorus, nitrogen, and potassium in the form of chemical fertilizers, manure, and sludge. It causes farms to discharge large quantities of agrochemicals, organic matter, and saline drainage into water bodies. It indirectly affects water pollution.

Pollutants can be of various types such as organic, inorganic, radioactive etc. Water pollutants are discharged either from one point from pipes, channels etc., which are called point sources or from various other sources. They can be agricultural areas, industries etc., called dispersed sources.

Some of the major forms of water pollutants are as follows:

Sewage- Domestic sewage from homes contains various forms of pathogens that threaten the human body. Sewage treatment reduces the risk of pathogens, but this risk is not eliminated.

Domestic sewage majorly contains nitrates and phosphates, and excess of these substances allows the algae to grow on the surface of water bodies. Due to this, the clean water bodies become nutrient-rich water body and then slowly, the oxygen level of water bodies reduces. This is called eutrophication or cultural eutrophication (if this step rapidly takes place by the activities of humans). This leads to the early death of water bodies.

Toxins- The industrial or factory wastes that are not disposed of properly and contain chemicals such as mercury and lead are disposed of in the water bodies making the bodies toxic, radioactive, explosive and cancerous.

Sediments- Sediments are the result of soil erosion that is formed in the water bodies. These sediments imbalances the water bodies ecologically. They also interfere in the reproductive cycle of various aquatic animals living in the water.

Thermal pollution- Water bodies get polluted because of heat, and excess heat reduces the oxygen level of the water bodies. Some of the species of fish cannot live in such water bodies with very low oxygen levels. The disposal of cold waters from the power plants leads to increased thermal pollution in the water bodies.

Petroleum oil pollution- The runoff of oil into the water bodies, either accidentally as happened in 2010 in the Gulf of Mexico, or intentionally, leads to an increase in water pollution.

As water is an important element of human health, polluted water directly affects the human body. Water pollution causes various diseases like typhoid, cholera, hepatitis, cancer, etc. Water pollution damages the plants and aquatic animals present in the river by reducing the oxygen content from the water. Polluted water washes the essential nutrients which plants need out of the soil and also leaves large amounts of aluminium in the soil, which can be harmful to plants.

Wastewater and sewage are a by-product of daily life and thus produced by each household through various activities like using soap, toilets, and detergents. Such sewage contains chemicals and bacteria which are harmful to human life and environmental health. Water pollution also leads to an imbalance in our ecosystem. Lastly, it also affects the food chain as the toxins in the water bodies are consumed by aquatic animals like fish, crabs etc., and then humans consume those animals forming turmoil.

Sometimes our tradition also becomes a cause for water pollution. Some people throw the statues of deities, flowers, pots, and ashes in rivers.

There are various standards to define water quality standards. Water meant for swimming may not be clean enough for drinking, or water meant for bathing may not be good for cooking. Therefore, there are different water standards for defined:

Stream standards- Standards that define streams, lakes, oceans or seas based on their maximum use.

Effluent standards- Define the specific standards for the level of contaminants or effluents allowed during the final discharge of those into the water bodies.

Drinking water standards- Define the level of contamination allowed in water that will be supplied for drinking or cooking in the domestic areas.

Different countries regulate their water quality standards through different acts and amendments.

While many of the solutions for water pollution need to be applied on a broader macro-level for that individual, companies, and communities can have a significant and responsible impact on the water quality. Companies, factories have to dispose of leftover chemicals and containers properly as per the product instructions. Farmers also have to reduce the use of nitrates and phosphates from fertilizers, pesticides, and contamination of groundwater.

The Swachh Bharat Mission of the government had led to reduced groundwater contamination. Under the Namami Ganga program, the government has initiated several major projects to clean Ganga. Along with all these steps, conservation of water is the very basic and important step towards water conservation and should be followed globally, treatment of sewage before their disposal in the water bodies and using environment-friendly products that do not form toxins when dissolved in water. These are some small steps that have to be taken into consideration by every human being.

As we all know, “Water is life’s matter and matrix, mother and medium. There is no life without water.” We have to save water. We must keep the water clean. If everyone will follow their responsibility against water to protect it from getting polluted then it will be easy to get clean and healthy drinking water. Clean water is a must for us and our kids' present, future, and healthy environment.

We cannot just live with contaminated waters filled with toxins and no oxygen. We cannot see our wildlife being destroyed and therefore, immediate steps have to be taken by groups of people to first clean the already contaminated water bodies and then keep a check on all the surrounding water bodies. Small steps by every individual can make a huge difference in controlling water pollution.

Water Pollution Prevention

Conserve Water

Our first priority should be to conserve water. Water wasting could be a big problem for the entire world, but we are just now becoming aware of it.

Sewage Treatment

Cleaning up waste materials before disposing of them in waterways reduces pollution on a large scale. By lowering its dangerous elements, this wastewater will be used in other sectors or in agriculture.

Usage of Eco-Friendly Materials

We will reduce the amount of pollution produced by choosing soluble products that do not alter to become pollutants.

Water contamination is the discharge of pollutants into the water body, where they dissolve, are suspended, are deposited on the bottom, and collect to the point where they hinder the aquatic ecosystem's ability to function. Water contamination is brought on by toxic compounds that easily dissolve and combine with it and come from factories, municipalities, and farms.

Healthy ecosystems depend on a complex network of organisms, including animals, plants, bacteria, and fungi, all of which interact with one another either directly or indirectly. In this article, we read about water pollution, its causes and prevention. With this, we have come to the end of our article, in case of any other doubts, feel free to ask in the comments.

FAQs on Water Pollution Essay

1. What are the effects of water pollution?

Water pollution has a great impact on human health. Water pollution kills. It's been recorded that in 2015 nearly 1.8 million people died because of water pollution. People with low income are exposed to contaminated water coming out from the industries. Presence of disease causing pathogens in drinking water are the major cause of illness which includes cholera, giardia, and typhoid. Water pollution not only affects human health but also our environment by causing algal bloom in a lake or marine environment. Water pollution also causes eutrophication which suffocates plants and animals and thus causes dead zones. Chemicals and heavy metals from industrial and municipal wastewater contaminate waterways and harm aquatic life.

2. What are the causes of Water pollution?

Water being a universal solvent is vulnerable to pollution as it dissolves more substances than any other liquid on earth. Therefore, water is easily polluted. Toxic substances from farms, towns, and factories readily dissolve into water and mix with it, resulting in water pollution. Agricultural pollution is one of the major causes of contamination in rivers and streams. The use of excessive fertilizers, pesticides, and animal waste from farms and livestock operations lets the rain wash the nutrients and pathogens—such as bacteria and viruses—into our waterways. The other major cause of water pollution is used water, termed as wastewater which comes from our sinks, showers, toilets and from commercial, industrial, and agricultural activities. It's been reported that the world's 80% wastewater flows back into the environment without being treated or reused. Oil spills and radioactive waste also cause water pollution to a great extent.

3. How to prevent water pollution?

It is important to keep our water bodies clean so we can take the following preventive measures to prevent from water pollution:

Chemicals like bleach, paint, paint thinner, ammonia, and many chemicals are becoming a serious problem. Dumping toxic chemicals down the drain or flushing them down the toilet can cause water pollution. Thus, proper disposal is important. Also, household chemicals need to be recycled.

Avoid buying products that contain persistent and dangerous chemicals. Buying non-toxic cleaners and biodegradable cleaners and pesticides cut down on water pollution.

Prevent from pouring fats or greasy substances down the drain as it might clog the drain resulting in the dumping of waste into yards or basement which can contaminate the local water bodies.

4. What is the role of medical institutions in polluting the water?

Pharmaceutical pollution affects aquatic life and thus there is a need to take preventive measures. Consumers are responsible for winding up pharmaceutical and personal care products in lakes, rivers, and streams. There's a lot of unused and expired medication that can potentially get into the water if not disposed of properly.

5. What are the major kinds of pollution?

The three main types of pollution are air pollution, water pollution or soil pollution. Some artificial pollution is also there, such as noise pollution. Factors leading to such pollution include:

Air Pollution: Industrial emissions, fires, traffic and transportation, burning of chemical waste, etc.

Water Pollution: No proper sewage disposal, pesticides in farms leaking into water bodies, industrial waste dumped into water bodies, etc.

Soil Pollution: Oil spills, acid rains, irresponsible disposal of trash, chemical waste, etc.

Noise Pollution: Honking of horns, construction activities, loud parties, etc.
