Water Pollution is called the contamination of water resources and underground resources of water by any of human activities or natural causes. Human activities such as urbanization, industrialization, deforestation, waste disposal, landfills are primarily responsible for water pollution.
Some of the natural causes responsible for water pollution are volcanoes and floods. Another natural cause for water pollution is algae bloom. A broad and varied group of photosynthetic organisms are referred to as “algae.” An algal bloom occurs when the number of algae in a body of water increases, causing the water to become contaminated and discolored.

The word “Water Pollution” is used when a water body such as ocean, river, lake, ocean, etc is toxic mainly due to human activity or by mean of nature. Nowadays, water pollution has become a major environmental concern and needs to be responsibly dealt with.
Every year Human lose tons of gallon of freshwater to industrial and other types of pollution. Pollutants consist of visible small and big pieces of garbage as well as invisible, harmful and toxic chemicals.
The visible impurities can be easily removed from a water body by manual cleaning or filtration, but the chemical pollutants are more dangerous and difficult to remove from water. The toxic chemicals get mixed into water and change its properties, making it harmful to use and life-threatening for living beings.
It is only through sincere individual and collective efforts, that we can overcome the problem of water pollution and prevent a severe water crisis in future.
Essay on Water Pollution in 200 words
Water Pollution is a matter of environmental concern as well as life and health of every species living on earth. For a population of 7.8 billion growing at a rate of 82 million per year we have a small number of little freshwater.
Almost 3% of all the water available on earth is freshwater which is used by us for our daily needs. But, human’s desire to expand boundaries and explore commercial avenues have put stress on our freshwater resources and made them polluted as never before.
There are many industries that are set up near water resources and use freshwater to carry industrial waste to the nearby river. This industrial waste is very toxic in nature and it damages the water quality.
The main reason for water pollution is urban waste and sewage. Every household produces tons of waste annually, which has plastic, wood, chemicals, and other compounds. In the absence of a proper waste disposal mechanism, this waste reaches water bodies like rivers, lakes, streams and pollutes them and it also affects water animals. Water pollution must be prevented if we want the earth to be green, healthy and filled with life for every species living on earth.
Essay on Water Pollution in 250 words
Water is an essential resource for life on earth and without water, or to be more specific, without clean and safe water, life on earth would be unbelievable. If you think that we still have plenty of water with it constituting 97.5% of the total volume of earth, but, this is not possible – that 97.5% is salt water that is found mainly in oceans; the water we do not use for our daily needs.
The remaining percentage, which is only 2.5%, is freshwater that we use in our day to day life. To be more specific, the total volume of water on earth is 1,386,000,000 Km3, out of which only 10,633,450 Km3 is freshwater and which is too much polluted. Leaving very little freshwater for a population of 7.8 billion and every year 82 million people are being added to that figure. On the other hand, the volume of freshwater used by the world population took a long time to be produced and thus it can’t be afforded to be polluted at any cost.
If the pollution of water continues as it is today, soon we could face a big water crisis. Then we might be left with no option but only to regret what we have done in our past. There is still time left and things can be normalized if we take proper action. Water conservation and pollution prevention are urgent issues that require both individual and group efforts.

Introduction
Water Pollution happens when external pollutants enter the otherwise clean and safe natural water resources and due to the growing human intervention and expansion of urban settlements, water pollution has become a painful reality today.
Water Pollution Sources
The reasons for water pollution are many and almost all of them are generated by human activities. Industries leave millions of gallons of toxic gas and material waste which is left directly into the air, water and natural resources. Most of these toxic waste from the industries are left directly into the water resource such as rivers or lakes without any kind of treatment. Also, the domestic waste that is generated by millions of households every day around the world contains waste plastic materials, chemicals, oils, metals, etc. Most of the households lack of proper knowledge a proper waste disposal mechanism and mostly the waste is directly dumped into the environment.
How to Stop Water Pollution
Raising awareness of water pollution’s origins and impacts on life and the environment could significantly reduce it. Participation in cleaning campaigns is required, wherein a community or organization takes on the duty of cleaning the water bodies at least once a month or every weekend.
Furthermore, in order to eradicate water contamination, stringent legislation must be created and rigorously enforced. Tight oversight will increase accountability and may stop individuals and groups from causing pollution.
Conclusion
Water pollution today has become a hot topic debate and concern for environmentalists and scientists. It is very dangerous for the future of all the living species on the planet earth. Water is an important commodity to live, added by the fact that only 2% of the water on earth is fresh water that can be used by living species.

Introduction
Water Pollution is known as the contamination of water bodies like rivers, lakes, ponds and oceans. The main reason for water pollution is generated by human activities like industrialization, urban waste, littering, etc., entering our water bodies and polluting them.
Types of Water Pollution
As water comes from many sources, there are many types of water pollution and the most common types of water pollution are described below.
- Agricultural/Nutrients Pollution
High quantities of nutrients can be found in some agricultural waste and waste water. Algae bloom as a result of these nutrient-rich pollutants, rendering the water unsafe for drinking and other uses. By using up the oxygen in the water, algae cause other species to run out of oxygen, which kills them.
- Sewage and Waste Water
Numerous soluble and insoluble contaminants, including plastic, rotten food, chemicals, debris, and mercury, are abundant in urban sewage and waste water. Some of these harmful substances sink to the bottom of water bodies, while others float to the top. All of the living things in the water body are at risk because the soluble contaminants alter the water’s makeup.
- Oxygen Depletion
Any water body contains many microorganisms including aerobic and anaerobic organisms. When the biodegradable waste reaches into the water bodies and decays, it will increase the growth of more microorganisms, consequently using more oxygen, in turn, depleting the oxygen level.
- Pollution of Ground Water
Use of chemical pesticides and fertilizers pollute the groundwater resources is a major reason to cause pollution under water. The chemicals get mixed with soil and are soaked into the ground with rain, and get to the underground water reserve. This toxic soil water reaches our wells and other sources of water, making its consumption harmful.
Prevention of Water Pollution
Water Pollution can be prevented by following these simple steps –
- Don’t pour down any kind of oil in your kitchen sink.
- Avoid improper disposing of harmful chemicals and other contaminants direct to the environment.
- Never let unused or expired medicines reach the house drainage system because it can affect water.
- Collect the waste as solid, liquid, degradable and non-degradable and ensure its proper disposal.
- Avoid using pesticides and chemical fertilizers as much as you can during the farming.
Conclusion
Water pollution is one of the major concerns for the environment which depletes one of our very essential natural resources. It is only through great determination and political will that we can succeed in saving water from getting contaminated in the near future.

Introduction
Water Pollution refers to the contamination of water bodies, primarily due to human activities. Water bodies such as lakes, rivers, ponds, oceans and underground water resources. Water Pollution happens when waste from industrial and other sources enter into the water bodies, resulting in the contamination of water, moreover, it is also harmful to aquatic life as well as to humans.
Water is a very important natural resource and very useful for life on earth. Causes of water pollution are many and it includes human activities. The many causes of water pollution are mentioned below-
Causes of Water Pollution
- Urban Sewage: The sewage from urban settlements is usually treated with chemicals and then released into the lakers or nearby river after mixing with freshwater. Most of the time, the garbage is not treated and is left into the river or lakes. It contains harmful bacteria and pathogens, which is extremely harmful to aquatic life as well as humans.
- Industrial Waste: Large amounts of toxic waste is produced by the industries and industrial waste includes pollutants such as mercury, lead, sulfur, asbestos, and nitrates. These chemicals are not only harmful to flora and fauna but also render the water unfit to use for our day to day activity. Due to the absence of a proper waste management system, many industries dump harmful waste in natural water resources.
- Garbage Dumping: Common household garbage consists of plastic, food, wood, paper, rubber, aluminum, etc and this garbage is directly dumped into oceans and rivers or else reaches them indirectly and takes a couple of years to centuries to degrade. In both cases, it pollutes the water bodies and threatens marine life.
- Landfills Leakage:Large heaps of trash that are typically located outside of cities or other urban settlements are known as landfills. Landfill waste contaminates water bodies when it leaks into them through rain or is carried by the wind. They are high in a number of pollutants that are bad for aquatic life.
Effects of Water Pollution
The most instant effect of water pollution is on the organisms that live in water. Moreover, it is also harmful to the surrounding plants, animals and humans that use water in some form or the other.
The pollution done chemically is most harmful in this regard as they are difficult to separate physically and alter the properties of water. They get mixed with the water and alter its chemical properties, making it harmful to consume to living animals.
Use of contaminated water can cause many serious diseases in humans like – diarrhea, cholera, typhoid, dysentery, etc and could be life-threatening.
Conclusion
Water Pollution nowadays has become a serious problem that concerns the health of the planet and its living being. Water is a very useful resource, much needed for drinking and other day to day activities by humans and wild animals and water animals alike. If the already scarce freshwater is contaminated then the chances of life on the planet are reduced, so to save life on earth we must first save the water by keeping our water bodies clean.
