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.

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.
102 Water Pollution Essay Topic Ideas & Examples
Water pollution essays are an excellent way to demonstrate your awareness of the topic and your position on the solutions to the issue. To help you ease the writing process, we prepared some tips, essay topics, and research questions about water pollution.
🌎 Air and Water pollution: Essay Writing Tips
🏆 best water pollution essay topics & examples, 📌 remarkable air and water pollution research topics, 👍 good research topics about water pollution, ❓ research questions about water pollution.
Water’s ready availability in many locations makes it an easy choice for a variety of purposes, from cleaning to manufacturing to nuclear reactor cooling. However, many companies will then dump water, now mixed with waste, back into rivers or lakes without adequate cleaning, leading to significant environmental pollution.
However, there are other types of harm, such as noise pollution, which are less obvious but also dangerous to sea life. It is critical that you understand what you should and should not do during your writing process.
The stance that big manufacturing industries are the sole culprits of the damage done to the world’s rivers and oceans is a popular one. However, do not neglect the effects of other water pollution essay topics such as microorganisms.
Microbes can spread dangerous illnesses, making them a danger for both water inhabitants and the people who then use that water. Furthermore, they can eat up oxygen if left unchecked, starving fish and other water organisms and eventually making them die out.
Such situations usually result from agricultural practices, which can lead to powerful nutrients entering the water and enabling algae and other microorganisms to grow excessively. An overly lively environment can be as harmful as one where everything is threatened.
With that said, industrial manufacturers deserve much of the attention and blame they receive from various communities. Construction of dedicated waste-cleaning facilities is usually possible, but companies avoid doing so because the process will increase their costs.
You should advocate for green practices, but be mindful of the potential impact of a significant price increase on the global economy. Also, be sure to mention more exotic pollution variations in your types of water pollution essay.
Provide examples of noise pollution or suspended matter pollution to expand on the topic of the complexity of the harm humanity causes to the ecosphere.
You should show your understanding that there are many causes, and we should work on addressing all of them, a notion you should repeat in your water pollution essay conclusions.
However, you should try to avoid being sidetracked too much and focus on the titles of pollution and its immediate causes.
If you stretch far enough, you may connect the matter to topics such as the status of a woman in Islam. However, doing so contributes little to nothing to your point and deviates from the topic of ecology into social and religious studies.
Leave the search for connections to dedicated researchers and concentrate on discussing the major causes that are known nowadays. By doing this, you will be able to create an excellent and powerful work that will demonstrate your understanding of the topic.
Here are some tips for your writing:
- Be sure to discuss the different types of pollution that is caused by the same source separately. Surface and groundwater pollution are different in their effects and deserve separate discussions.
- Focus on the issues and not on solutions, as an essay does not provide enough space to discuss the latter in detail.
- Be sure to discuss the effects of pollution on people and other land inhabitants as well as on water creatures.
