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.

Essay on Water Pollution in 500 Words

The term “water pollution” is employed when human or natural factors lead to contamination of bodies of water, such as rivers, lakes, and oceans. Responsible management is now imperative to address this significant environmental concern. The primary sources of water contamination are human-related activities like urbanization, industrialization, deforestation, improper waste disposal, and the establishment of landfills.

Reasons for Water Pollution

The availability of freshwater on our planet is limited, and pollution only increases this scarcity. Every year, a substantial amount of fresh water is lost due to industrial and various other types of pollution. Pollutants encompass visible waste items of varying sizes as well as intangible, hazardous, and lethal compounds.

Numerous factories are situated in proximity to water bodies, utilizing freshwater to transport their waste. This industrial waste carries inherent toxicity, jeopardizing the well-being of both plant and animal life. Individuals living close to polluted water sources frequently suffer from skin problems, respiratory ailments, and occasionally even life-threatening health conditions.

Water contamination is also intensified by urban waste and sewage, adding to the problem. Each household generates considerable waste annually, including plastic, chemicals, wood, and other materials. Inadequate waste disposal methods result in this refusal to infiltrate aquatic ecosystems like rivers, lakes, and streams, leading to pollution.

Methods of Water Pollution Management

Raising awareness about the causes and consequences of water pollution is crucial in significantly reducing its prevalence. Encouraging community or organizational clean-up initiatives on a weekly or monthly basis plays a pivotal role. 

To eradicate water contamination completely, stringent legislation needs to be formulated and diligently enforced. Rigorous oversight would promote accountability, potentially deterring individuals and groups from polluting. Each individual should recognize the impact of their daily actions and take steps to contribute to a better world for generations to come.

My affection for my town has always been heightened by its abundant lakes, rivers, and forests. During one of my walks alongside the river that flowed through my village, I was struck by the unusual hues swirling within the water. The once-familiar crystal-clear blue had been replaced by a murky brown shade, accompanied by a potent, unpleasant odour. Intrigued, I decided to investigate further, descending to the riverbank for a closer look at the source of the peculiar colours and smells. Upon closer inspection, I observed peculiar foam bubbles floating on the water’s surface.

Suddenly, a commotion behind me caught my attention, and I turned to witness a group of people hastening toward the river. Their frantic shouts and vigorous gestures conveyed their panic, prompting me to realize that a grave situation was unfolding. As the group reached the river, they were confronted with the distressing sight of numerous lifeless fish floating on the water’s surface. 

Following a comprehensive investigation, it was revealed that a local factory had been releasing toxic chemicals into the river, resulting in extensive pollution and the devastation of the ecosystem. This investigation left me stunned and disheartened, acknowledging the significant effort required to restore the river to its own form.

Introduction

Causes and effects of water pollution, possible solutions for water pollution.

Water pollution is any form of activity that may lead to contamination or addition of pollutants into water body. It is an important issue to the world to put into consideration because human beings need clean water. Other living creatures need good water as well.

Therefore, water is a very important requirement in the daily activities of people, and it is a very useful resource in industries, hospitals, schools and even in food manufacturing companies. This is why clean water is required in all the places to make sure the people and all the living creatures in the planet live a good and healthy life.

Water pollution cases have been increasing in the contemporary world, despite all the efforts to reduce it. Despite all these efforts, the question remains as to what steps the world should take to end this problem of water pollution.

Harmful and toxic pollutants cause most cases of water pollution. The pollutants may cause the water to change both its physical or chemical nature by causing mixed reactions with its contents. One of the major pollutants is waste chemicals from manufacturing industries or factories.

Most of these institutions are careless with this matter of water pollution. This is actually a very serious matter because most of the people concerned know the effects of this activity but they end up ignoring it. Moreover, these wastes contain very harmful and toxic chemicals that may cause health problems to human beings and other living creatures in the water body.

Another major pollutant is sewage. Sewage dumped to various water bodies such as rivers, lakes or sea is a direct harm to the nearby occupants, given that it is there main source of water. This will mean that these people will lack clean water and will have one option of drinking the dirty water. The toxic contents of the sewage may also harm or kill aquatic animals present in that particular water body. Indeed, this is a government concern, though it seems that it is being neglected all the time.

Oil spillage to water bodies is another cause of water pollution, as it leads to more harmful effects to the living creatures and human beings around. Oil spillage will definitely affect the health of aquatic organisms, as well as other living things dependent on the water body being polluted. Garbage and other toxic substances are also the other causes of water pollution. All these directly affect human health and the natural environment in the surrounding areas. It is therefore up to the government to put more efforts to reduce these problems.

One of the best solutions to water pollution is the enactment and implementation of rules against those industries and institutions that carelessly dump waste chemicals, garbage, and other toxic pollutants to the water bodies without considering human life and the natural habitat around. The government would need to be very strict on this matter.

People should also avoid dumping litter, household waste, or garbage to water bodies. Individuals should also avoid throwing dirty and harmful substances to their water lines that drain to sewage. Individual farmers must try to use the right amount of fertilizer when applying chemicals, as excess amount of fertilizer may drain to the nearby water body.

Water pollution issues are currently increasing in the world because of neglect of the governments and ignorance of the people. Water pollution issue should not only be issue to the government, but also all the people in the society. Therefore, people should join hands together with the government to reduce this world’s major problem. Nevertheless, water is a very important resource in the world, and it should therefore be kept clean and safe.

Essay on Water Pollution in English (500 Words)- Water, the essence of life, is a precious natural resource that sustains all living beings on Earth. However, rapid industrialization, urbanization, and human activities have led to a significant increase in water pollution, posing a severe threat to ecosystems, human health, and the overall well-being of the planet. Water pollution refers to the contamination of water bodies such as rivers, lakes, oceans, and groundwater by various pollutants, resulting in detrimental impacts on aquatic life and humans.

Causes of Water Pollution

Water pollution is a complex issue with multiple interconnected causes, including:

• Industrial Discharges: Factories and industries release a wide range of chemicals, heavy metals, and waste materials into water bodies, contaminating them and disrupting the natural balance.
• Agricultural Runoff: The excessive use of fertilizers, pesticides, and herbicides in agriculture leads to runoff that carries these chemicals into waterways, causing nutrient imbalances and harmful algal blooms.
• Improper Waste Disposal: Inadequate waste management and improper disposal of household and municipal waste can result in sewage and other pollutants entering water bodies, spreading diseases and degrading water quality.
• Oil Spills: Accidental or deliberate oil spills from ships and oil rigs release large quantities of hydrocarbons into oceans, severely damaging marine ecosystems and wildlife.
• Urbanization: Urban areas generate pollutants such as litter, plastics, and chemicals that find their way into water bodies through stormwater runoff.
• Deforestation: Deforested areas experience increased soil erosion, leading to sedimentation in rivers and streams, which affects water quality and aquatic habitats.

Consequences of Water Pollution

The consequences of water pollution are far-reaching and impact various aspects of the environment and human well-being:

• Ecological Imbalance: Water pollution disrupts aquatic ecosystems by altering the composition of aquatic species, causing habitat destruction, and promoting the growth of harmful algae.
• Health Risks: Contaminated water is a breeding ground for waterborne diseases such as cholera, typhoid, and hepatitis, posing serious health risks to those who consume or come in contact with polluted water.
• Economic Losses: Polluted water bodies lead to loss of fisheries, tourism, and other economic activities that rely on clean water resources.
• Biodiversity Loss: Aquatic organisms suffer from the impacts of pollution, leading to reduced biodiversity and, in extreme cases, species extinction.
• Drinking Water Scarcity: Pollution of freshwater sources reduces the availability of safe drinking water, which is a fundamental human necessity.

How to Reduce Water Pollution?

Addressing water pollution requires collective efforts from governments, industries, communities, and individuals:

• Stringent Regulations: Governments should enact and enforce strict environmental regulations to limit pollutant discharges from industries and other sources.
• Waste Management: Improving waste management systems, promoting recycling, and implementing proper sewage treatment are crucial to prevent pollutants from entering water bodies.
• Sustainable Agriculture: Encouraging sustainable farming practices that reduce the use of harmful chemicals and promote soil conservation can minimize agricultural runoff.
• Renewable Energy Transition: Transitioning to cleaner energy sources can reduce the risk of oil spills and other hydrocarbon-related pollution.
• Riparian Zone Protection: Establishing buffer zones along water bodies through afforestation and vegetation conservation helps filter pollutants before they reach waterways.
• Public Awareness: Educating communities about the importance of water conservation and pollution prevention can drive individual actions towards reducing pollution.

Water pollution is a pressing global concern that demands immediate attention and collective action. As stewards of the planet, it is our responsibility to protect and preserve water resources for present and future generations. Through robust regulatory measures, sustainable practices, and public awareness, we can work towards mitigating the causes and consequences of water pollution, ensuring a healthier and more sustainable future for all.

Water Pollution Essay Example #1

Water pollution is a pressing issue that affects the health of our planet and its inhabitants. It occurs when harmful substances are introduced into bodies of water, such as rivers, lakes, and oceans, leading to detrimental effects on aquatic ecosystems and human health. In this essay, we will explore the causes of water pollution, examine its effects, and discuss potential solutions to mitigate this environmental problem.

Water pollution is primarily caused by human activities, which often result in the discharge of pollutants into water bodies. One of the main contributors to water pollution is industrial waste. Factories and manufacturing processes release various chemicals and toxins into nearby water sources. For example, heavy metals, such as mercury and lead, can be found in industrial wastewater, posing a significant threat to aquatic life and human health. Agricultural activities also play a significant role in water pollution. The use of fertilizers, pesticides, and herbicides in farming practices can lead to runoff, carrying these chemicals into nearby water bodies. This runoff not only contaminates the water but also disrupts the balance of nutrients, leading to harmful algal blooms and the depletion of oxygen levels, which can be fatal to aquatic organisms. Furthermore, urbanization has a significant impact on water pollution. Improper disposal of sewage and stormwater runoff can contaminate water sources with harmful bacteria and pathogens. Inadequate wastewater treatment facilities and aging infrastructure contribute to the release of untreated sewage into rivers and oceans, posing a threat to both aquatic life and human health.

To address the issue of water pollution, it is crucial to implement effective solutions. Regulatory measures play a vital role in mitigating water pollution. Governments must enforce strict environmental laws and regulations to ensure that industries and agricultural activities adhere to proper waste management practices. This includes monitoring and limiting the discharge of pollutants into water bodies. Improved waste management practices are also essential in reducing water pollution. Industries should invest in proper treatment and disposal methods for their waste, minimizing the release of harmful substances into water sources. Similarly, farmers must adopt sustainable agricultural practices, such as using organic fertilizers and implementing erosion control measures, to prevent runoff and contamination.

Water Pollution Essay Example #2

Water pollution is a pressing issue that affects both the environment and human health. With the increasing industrialization and urbanization of societies, the contamination of water sources has become a major concern. This essay will explore the sources of water pollution, the impact it has on the environment, and the consequences it has on human health. By understanding the causes and effects of water pollution, we can work towards implementing effective solutions to mitigate its detrimental effects.

Water pollution has a profound impact on the environment, particularly on aquatic ecosystems. The contamination of water bodies can result in the death of fish, plants, and other aquatic organisms. For instance, when industrial pollutants or agricultural runoff enter a river, the high concentrations of chemicals or excess nutrients can cause fish kills, as the organisms are unable to survive in such conditions. Additionally, water pollution leads to a loss of biodiversity. As certain species are unable to tolerate the polluted environment, their populations decline, disrupting the natural balance of ecosystems. Moreover, excessive nutrients in water bodies, such as nitrogen and phosphorus from agricultural runoff, can trigger algal blooms. These blooms deplete oxygen levels in the water, creating dead zones where aquatic life cannot survive. This further exacerbates the destruction of aquatic ecosystems and the loss of biodiversity.

Water pollution not only harms the environment but also poses significant risks to human health. Contaminated water is a major carrier of waterborne diseases, which can have severe consequences for communities. For example, the consumption of water contaminated with fecal matter can lead to diseases such as cholera, typhoid, and dysentery. These diseases can cause severe dehydration and even death, particularly in areas with limited access to clean water and sanitation facilities. Furthermore, exposure to certain pollutants in drinking water can increase the risk of cancer. Heavy metals such as arsenic and lead, as well as chemicals like pesticides and industrial solvents, have been linked to the development of various types of cancer. Lastly, water pollution has negative effects on livelihoods. Polluted water affects industries such as fishing, agriculture, and tourism, leading to economic losses for communities dependent on these activities. For instance, contaminated water bodies can result in the death of fish populations, impacting the livelihoods of fishermen and the availability of a valuable food source.

Water Pollution Essay Example #3

The consequences of water pollution on the environment are far-reaching. One of the most significant impacts is the destruction of aquatic ecosystems and the loss of biodiversity. Pollutants in the water can disrupt the delicate balance of these ecosystems, leading to the death of aquatic plants and animals. This disruption can have a cascading effect on the entire food chain, ultimately resulting in the loss of biodiversity. Water pollution also poses a threat to the availability of safe drinking water sources. Contaminated water sources can contain harmful bacteria, viruses, and chemicals, making them unfit for human consumption. This can lead to widespread outbreaks of waterborne diseases, such as cholera and dysentery, particularly in areas with inadequate access to clean water and sanitation facilities. Furthermore, water pollution has detrimental effects on marine life and fisheries. Toxic chemicals and pollutants can accumulate in the tissues of marine organisms, making them unsafe for consumption. This not only impacts the livelihoods of communities dependent on fishing but also disrupts the delicate balance of marine ecosystems, leading to the decline of fish populations and the loss of valuable marine species.

“We never know the worth of water till the well is dry – Save Water”

Water Pollution Essay – Sample 1 (250+ Words)

Water pollution can be defined as the introduction of pollutants into a water body. These pollutants can impact life by causing disruptions in life processes. On a bigger scale, water pollution can compromise the stability of the environment by affecting food chains. Water is a universal solvent, hence it is relatively easy for most substances to dissolve in it. This property makes water very vulnerable to pollution . And for the most part, humans are to blame. Granted, water pollution can also occur naturally, but most of the high-impact causes are anthropogenic or man-made.

Water pollution can manifest itself in many forms – for instance, eutrophication is a phenomenon where large quantities of nutrients are introduced into a water body, and as a result, excessive plant growth occurs. Though this may sound harmless, these plants decrease the available dissolved oxygen in the water, thereby starving fish and other aquatic organisms of oxygen. Furthermore, these plants can secrete toxins that can potentially kill animals. The fumes that these plants create can also have disastrous consequences when exposed to animals or humans.

Anthropogenic causes of water pollution can be observed in the form of dumping sewage and untreated wastes into water bodies. This can drastically affect organisms in the water body. Moreover, through bioaccumulation, these mineral toxins can make their way up the food chain and into the human diet. The Minamata Incident, which occurred in Japan is a testimony to the fatal effects of water pollution. Even to this day, a part of the population is still living with illnesses due to exposure to mercury from seafood.

In conclusion, we need to curb water pollution, else risk more life-threatening scenarios.

Water Pollution Essay – Sample 2 (350+ Words)

Water pollution can be defined as the introduction of foreign pollutants into a body of water. These pollutants can have dire consequences on human health and the environment. Water pollution can either be caused by natural causes or anthropogenic causes. For instance, eutrophication is a phenomenon where excessive nutrients are introduced into the water body, causing the rapid formation of plants. This causes algal bloom that can harm aquatic life and destabilize the food chain.

What is Water Pollution?

This process can occur naturally, where the nutrients that are already present in the water body are brought to the surface through water currents. When this happens, a favorable environment for the plants (more specifically alage) is formed. With enough nutrients and sunlight, the plants flourish rapidly and eutrophication occurs. Humans can also bring about eutrophication when they dump sewage or other untreated wastes into water bodies. Moreover, when cut grass is disposed of in water bodies, eutrophication happens.

Effects of Water Pollution on Human Health

Effects of Water Pollution on Human Health. Water pollution also has the disastrous effect of causing a number of life-threatening illnesses in humans. This occurs when fecal matter from sanitary units (or bathrooms) seep into the soil, where it infiltrates water sources, thereby contaminating it. If this water is consumed, it can lead to many water-borne illnesses such as Cholera, Dysentery and typhoid fever. Besides this, even more, serious illness can be spread through contaminated drinking water.

Minamata Incident – A Severe Case of Water Pollution

In 1932, a factory in Japan started to dump its industrial effluents into the surrounding sea. One of the waste products was Methylmercury, an extremely toxic chemical to humans. This toxic chemical had bioaccumulated inside the tissues of shellfish and other fish endemic to that region. The local population was heavily reliant on seafood, hence, when they started consuming the poisoned shellfish and other aquatic organisms, they began to fall it. Initially, the cause could not be attributed to a single source.

However, even more, people started to fall sick and more serious illnesses manifested. The nervous system was affected, causing motor impairment and paralysis. This had continued for another 36 years before the real cause was found and action taken. Today, this event is infamously called the Minamata Incident, one of the most damaging consequences of water pollution.

In conclusion, water pollution is a type of pollution that can have very severe consequences. Ensure the necessary precautions are taken so that such events in the future may not occur.

FAQ’s on Water Pollution

Question 1. What is Water Pollution?

Answer: Water pollution can be defined as the introduction of foreign pollutants into a body of water, typically a river, lake or even an ocean.

Question 2. What are the two primary causes of water pollution?

Answer: Water pollution can occur either through anthropogenic causes – which is man-made or through natural causes. Though most of the harmful impacts are caused by man-made sources.

Essay on Water Pollution

An essay is a piece of writing that revolves around a particular theme and contains the academic opinions of the person writing it. A basic essay mainly consists of three parts: Introduction, Body, and Conclusion.

Contamination of water bodies because of the discharge of pollutants into them is known as water pollution. After going through the Essay on Water Pollution, you will be able to understand the sources and effects of Water pollution and how to deal with it.

Daily Test - Attempt Now

According to the World Health Organization, any foreign matter either natural or other sources which contaminates and pollutes the water or the water supply making it harmful to human and aquatic life is termed water pollution.

Gases, minerals, humus, and wastes created by living organisms are some natural wastes that pollute water. Industrial wastes include heavy metals and synthetic organic compounds. The discharge of these wastes into water bodies causes water pollution. Lead, manganese, and mercury affect marine life .

Drilling oil under the sea may prove dangerous for marine life. Oil is transported to distant places by ships. An oil spill or tragedy at sea wherein the ship capsizes causes the degradation of marine and aquatic organisms. It also threatens ecosystems that exist under the sea.

Water pollution may severely affect human, plant, and animal life. Accumulation of Nutrients and chemicals into water bodies results in the growth of phytoplankton and algae. This obstructs the penetration of oxygen and sunlight into water bodies which may result in the death of aquatic organisms.

When contaminated water is consumed, the pathogens enter the human body. It may cause various water-borne diseases such as typhoid, cholera, diarrhoea, dysentery, and jaundice. Metals such as lead, mercury, and cadmium dissolved in water may cause several diseases if they enter the human body. When water contaminated with cadmium was consumed by the Japanese, they were affected by a disease called itai-itai. Similarly, a disease known as Minamata affected the Japanese after they consumed fish that had a large concentration of mercury.

When phosphorus and nitrates from fertilizers are disposed of in water bodies, they promote the growth of algae. The presence of algae in water bodies in a large number reduces the amount of dissolved oxygen in water resulting in the death of fish and other water organisms.

Industrial effluents include chemicals such as mercury, lead, and cadmium. When these chemicals reach the human body through the consumption of fish, they may cause irritation, insomnia, and nervous disorders, which may also affect the brain.

Thermal pollution increases the temperature of the water which in turn reduces the level of oxygen in the water. This results in the death of many species of fish. Oil drilling and oil spills contaminate seawater which may also lead to the death of marine organisms.

Measures should be taken to prevent water pollution before the situation goes out of control. Anti-pollution scientific methods should be devised.

Sources of water pollution which cause an inflow of pollutants over a large area are known as non-point sources. Example: Runoff from agricultural fields. The following steps should be taken to reduce water pollution from non-point sources:

• Two separate drainages should be built for sewage and rainwater so that both rainwater and sewage do not overflow together.
• Nitrogen-fixing plants should be planted to reduce the use of chemical fertilisers.
• Agrochemicals and pesticides should be used judiciously to prevent them from draining into a water body.
• Efforts should be made to prevent the runoff of manures.
• Bio fertilisers and biopesticides should be used.

Sources that discharge pollutants to only one specific site are known as point sources. Example: Discharge of effluents from the factory into a river. To prevent pollution from point sources, it is essential to first treat wastewater before it is discharged. Laws should be made carrying strict punishment for discharging untreated wastewater into any water body.

After going through the essays, you will know what water pollution is and what are its main causes; how to stop water pollution; water pollution prevention etc. These essays will be helpful in your school/college assignments of essay writing, speech giving or paragraph writing, etc.

Water Pollution Essay 100 Words – Sample 1

Water Pollution refers to the contamination of water bodies and underground resources of water by any of the several human activities or natural causes. Human activities like, urbanization, industrialization, deforestation, waste disposal, landfills are primarily responsible for water pollution.

Some of the natural causes responsible for water pollution are volcanoes and debris from floods. Another natural cause of water pollution is algae bloom. The term “algae” is used to refer to a large and diverse group of photosynthetic organisms. Algae bloom means an increase in the population of algae in a water body, consequently resulting in its discoloration and contamination.

Water Pollution Essay 150 Words – Sample 2

The term “Water Pollution” is used when a water body like a river, lake, ocean, etc is polluted due to human activity or a natural cause. Today, water pollution has become a major environmental concern and needs to be responsibly dealt with.

Fresh water is very scarce on the planet and pollution is making it even scarcer. Every year we lose millions of liters 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 hazardous and difficult to remove. Chemicals get mixed into water and change its properties, making it harmful to use and life-threatening.

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.

Water Pollution Essay 200 Words – Sample 3

Water Pollution is a matter of environmental concern as well as life and health of all living species. For a population of 7.8 billion growing at a rate of 82 million every year we have very little freshwater.

Only 2.5% of all the water available on earth is freshwater that we use for our daily needs. But, human’s desire to expand boundaries and explore commercial avenues have put stress on our freshwater resources, making them polluted as never before.

Many industries are set up near water bodies and use freshwater to carry industrial waste to the nearby water bodies. This industrial waste is toxic in nature and poses a health hazard to the flora and fauna. People in the settlements in the vicinity of polluted water bodies are observed to be suffering from serious skin, respiratory and sometimes even life-threatening other ailments.

Other the main cause of water pollution is urban waste and sewage. Every household produces tons of waste annually, consisting of plastic, wood, chemicals, and other compounds. In the absence of a proper waste disposal mechanism, this waste reaches our water bodies like rivers, lakes, streams and pollutes them. Water pollution must be prevented if we want the earth to be green, healthy and filled with life.

Water Pollution Essay 250 Words – Sample 4

Water is an essential resource for life on earth. Without water, or to be more specific, without clean and safe water, life on earth would be unimaginable. You may think that we still have plenty of water with it constituting 97.5% of the total volume of earth. But, there is a catch – 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, that is, only 2.5% is freshwater what we use. Moreover, only 0.3% of that 2.5% is the water found on the surface of the earth. To be more specific, the total volume of water on earth is 1,386,000,000 Km 3 , out of which only 10,633,450 Km 3 is freshwater. Leaving very less freshwater for a population of 7.8 billion as on December 2019 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 centuries 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, within a couple of decades we could face an acute water crisis. Then we might be left with no option but only to regret what we have done. There is still time and things can be normalized if we take action today. Whether it is an individual action or a collective one, an action to conserve water and prevent its pollution is the need of the day.

Water Pollution Essay 300 Words – Sample 5

Introduction

Water Pollution occurs when external pollutants enter the otherwise clean and safe natural water resources. Due to the growing human intervention and expansion of urban settlements, water pollution has become a painful reality today.

Water Pollution Sources

The sources of water pollution are many and almost all of them are generated due to human activities. Industries emit millions of gallons of toxic smoke and material waste which is left directly into the air, water bodies and natural resources. Most of such waste from the industries are left directly into the water bodies without any kind of treatment. Most of the industrial waste is toxic in nature and in turn, increases the toxicity of the water it reaches.

Also, the domestic waste that is generated every day in the millions of households around the world contains waste plastic materials, chemicals, oils, metals, etc. Most of the households lack a proper waste disposal mechanism and mostly the waste is directly dumped into the environment.

How to Stop Water Pollution

Water pollution could be prevented considerably by making people aware of its causes and its effects on life and the planet. People must take part in cleaning campaigns wherein a group or community takes up the task of cleaning the water bodies every weekend or at least once in a month.

Moreover, strict laws need to be formed and strictly implemented with the objective of eliminating water pollution. Strict monitoring could prevent people and organizations from polluting and will improve accountability as well.

Water pollution today has become a topic of hot debate and concern for environmentalists and scientists. It threatens the future of all the living species on the planet earth. Water is an essential commodity to live added by the fact that only 2% of the water on earth is fresh water that we use. We can’t afford to pollute it further and must take steps for the reversal of the damage that we have already done.

Water Pollution Essay 350 Words – Sample 6

Water Pollution refers to the introduction of pollutants into our water bodies. These pollutants are primarily generated by human-induced activities and pose a threat to our natural water resources.

Water Pollution Prevention

There are several things one could do to prevent water pollution. Some of them are simple enough to be taken by an individual while some require collective efforts. However, the efforts need to be repeatedly done in order to preserve our natural water resources. Some of the implementable ways to prevent water pollution are given below-

Keep your drain free of Contaminants and Chemicals.

An average household generates all kinds of waste including chemicals, disposed medicines, and other hazardous compounds. We must take care while disposing of our household waste and ensure that any such waste didn’t reach the sewage system.

Prevent use of Polythene

Polythene bags are widely used today in every household. They are light, could carry heavyweight, and easy to store. But polythene bags constitute a major threat to water resources. The polythene that we dispose of our houses, finds its way into the water bodies. Being non-biodegradable, it just lays there, polluting water and making it toxic.

Conserve Water

Always try to conserve water while doing your daily activities, whether it’s cooking, shaving, bathing, gardening or cleaning, etc. Water conservation can also be achieved by repairing all the faulty taps in your house and locality as well.

Reuse and Recycle

Much of the waste that we generate in houses could be reused and recycled if only we make a little effort for it. Wastes like automobile oil are disposed into the drain and easily reach into rivers and streams. This is really hazardous to the purity of water and also to the life of organisms that live in water. On the other hand, automobile oil can be reused for several other lubrication purposes.

Water pollution today has become a cause of great concern for human health as well as the environment. Water is an essential commodity without which life can’t be imagined. It is the duty of all to take steps for keeping water pollution-free and also to conserve it, for a healthy future of the planet.

Water Pollution Essay 400 Words – Sample 7

Water Pollution refers to the contamination of water bodies like rivers, lakes, ponds and oceans. It is caused when the pollutants generated by human activities like industrialization, urban waste, littering, etc., enter our water bodies and pollute them.

Types of Water Pollution

As water comes from many sources, there are many types of water pollution. The most common types of water pollution are described below.

• Agricultural/Nutrients Pollution

Some of the waste water and agricultural waste contain high nutrients levels. These nutrient-rich contaminants cause algae growth, making the water unfit for drinking and other purposes. Algae use the oxygen content in water making oxygen scarce for other organisms, resulting in their death.

• Sewage and Waste Water

Sewage and waste water from urban settlements is rich in various soluble and non-soluble impurities like mercury, plastic, rotten food, debris, chemicals etc. When these pollutants reach water bodies, some of them float over the surface while some sink at the bottom. The soluble impurities change the composition of water as well. This is a dangerous situation for all the living organisms in the water body.

• Oxygen Depletion

Any water body contains several microorganisms including aerobic and anaerobic organisms. When the biodegradable waste reaches into the water bodies and decays, it encourages 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. The chemicals get mixed with soil and are soaked into the ground with rain, reaching the underground water reserve. This contaminated water reaches our wells and other sources of water, making its consumption harmful.

Prevention of Water Pollution

Water Pollution can be prevented by taking these simple steps –

• Don’t pour down fat or oil in your kitchen sink.
• Avoid improper disposing of harmful chemicals and other contaminants.
• Never let unused or expired medicines reach the house drainage system.
• Segregate 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.

Water pollution is a growing environmental concern 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.

Water Pollution Essay 500 Words – Sample 8

Water Pollution refers to the contamination of water bodies, primarily due to human activities. Water bodies include lakes, rivers, ponds, oceans and underground water resources. Water Pollution occurs 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.

Causes of Water Pollution

Water is an essential natural resource and very useful for life on earth. Causes of water pollution are many and always include human activities. The various causes of water pollution are given below-

• Urban Sewage: The sewage from urban settlements is usually treated with chemicals and then released into the water bodies after mixing with fresh water. Most of the time, the sewage is not treated and is left into the water bodies. It contains harmful, bacteria and pathogens, which is extremely harmful to aquatic life and to humans as well.
• Industrial Waste: Large amount of toxic waste is produced by the industries. 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. Due to the absence of a proper waste management system, many industries still dump harmful waste in natural water resources.
• Garbage Dumping: Common household garbage contains plastic, food, wood, paper, rubber, aluminum, etc. 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 as well as the life of flora and fauna over the adjoining lands.
• Oil Spills: Oil is non-soluble in water and being lighter in density, floats over it. Though the oil spills have been considerably reduced in the past decades, the incidents of oil spills still happen. For instance, in 2018, there were 137 oil spills in the United States alone. Out of 137 spills, 65 were reported as the maximum potential spills, releasing gallons of oil into the water.
• Landfills Leakage: Landfills are the huge piles of garbage usually found on the outskirts of a city or urban settlement. The garbage from the landfills leaks into the water bodies with rain or reaches with the wind, resulting in their contamination. They contain a large amount of several contaminants harmful for aquatic life.

Effects of Water Pollution

The most immediate effect of water pollution is on the organisms that live in water. Moreover, it is also harmful to the surrounding plants, animals and humans those use or consume water in some form or the other.

Chemical pollutants are most harmful in this regard as they are difficult to separate physically and alter the properties of water. They get mixed with the water alter its chemical properties, making it harmful to consume or use.

Use of contaminated water causes several serious diseases in humans like – diarrhea, cholera, typhoid, dysentery, etc and could be life-threatening.

Water Pollution today has become a serious issue that concerns the health of the planet and its inhabitants. Water is a very useful resource, much needed for drinking and other essential activities by humans and animals alike. If the already scarce freshwater is made contaminated then the chances of life on the planet are considerably reduced. To save life on earth we must first save the water by keeping our water bodies clean.

What is water pollution?

Water pollution is the release of substances into bodies of water that makes water unsafe for human use and disrupts aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste , petroleum , and disease-causing microorganisms .

What human activities cause water pollution?

Human activities that generate domestic sewage and toxic waste cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances. Oil spills are another source of water pollution that have devastating impacts on surrounding ecosystems.

Sewage can promote algae growth, which can eventually result in eutrophic “dead zones” where aquatic life cannot survive because of a lack of oxygen. Microplastics are often found in marine wildlife and can become concentrated in humans who consume seafood because of biomagnification . Oil spills, such as the Deepwater Horizon oil spill in 2010, strand and kill many different marine species.

While some studies point to human activity as a catalyst for red tide, scientists are unsure about its cause. Red tide is a common term for harmful algal blooms that often poison or kill wildlife and humans who consume contaminated seafood. Red tides can severely impact ecosystems and local economies.

water pollution , the release of substances into subsurface groundwater or into lakes , streams, rivers , estuaries , and oceans to the point that the substances interfere with beneficial use of the water or with the natural functioning of ecosystems . In addition to the release of substances, such as chemicals , trash, or microorganisms, water pollution may include the release of energy , in the form of radioactivity or heat , into bodies of water.

Types and sources of water pollutants

Water bodies can be polluted by a wide variety of substances, including pathogenic microorganisms, putrescible organic waste, fertilizers and plant nutrients , toxic chemicals, sediments, heat , petroleum (oil), and radioactive substances . Several types of water pollutants are considered below. (For a discussion of the handling of sewage and other forms of waste produced by human activities, see waste disposal and solid-waste management .)

Water pollutants come from either point sources or dispersed sources. A point source is a pipe or channel, such as those used for discharge from an industrial facility or a city sewerage system . A dispersed (or nonpoint) source is a very broad unconfined area from which a variety of pollutants enter the water body, such as the runoff from an agricultural area. Point sources of water pollution are easier to control than dispersed sources, because the contaminated water has been collected and conveyed to one single point where it can be treated. Pollution from dispersed sources is difficult to control, and, despite much progress in the building of modern sewage-treatment plants, dispersed sources continue to cause a large fraction of water pollution problems.

Domestic sewage is the primary source of pathogens ( disease -causing microorganisms) and putrescible organic substances. Because pathogens are excreted in feces , all sewage from cities and towns is likely to contain pathogens of some type, potentially presenting a direct threat to public health . Putrescible organic matter presents a different sort of threat to water quality. As organics are decomposed naturally in the sewage by bacteria and other microorganisms, the dissolved oxygen content of the water is depleted. This endangers the quality of lakes and streams, where high levels of oxygen are required for fish and other aquatic organisms to survive. In addition, domestic sewage commonly contains active pharmaceutical ingredients, which can harm aquatic organisms and may facilitate antibiotic resistance . Sewage-treatment processes reduce the levels of pathogens and organics in wastewater, but they do not eliminate them completely ( see also wastewater treatment ).

Domestic sewage is also a major source of plant nutrients , mainly nitrates and phosphates . Excess nitrates and phosphates in water promote the growth of algae , sometimes causing unusually dense and rapid growths known as algal blooms . When the algae die, oxygen dissolved in the water declines because microorganisms use oxygen to digest algae during the process of decomposition ( see also biochemical oxygen demand ). Anaerobic organisms (organisms that do not require oxygen to live) then metabolize the organic wastes, releasing gases such as methane and hydrogen sulfide , which are harmful to the aerobic (oxygen-requiring) forms of life. The process by which a lake changes from a clean, clear condition—with a relatively low concentration of dissolved nutrients and a balanced aquatic community —to a nutrient-rich, algae-filled state and thence to an oxygen-deficient, waste-filled condition is called eutrophication . Eutrophication is a naturally occurring, slow, and inevitable process. However, when it is accelerated by human activity and water pollution (a phenomenon called cultural eutrophication ), it can lead to the premature aging and death of a body of water.

The improper disposal of solid waste is a major source of water pollution. Solid waste includes garbage, rubbish, electronic waste , trash, and construction and demolition waste, all of which are generated by individual, residential, commercial, institutional, and industrial activities. The problem is especially acute in developing countries that may lack infrastructure to properly dispose of solid waste or that may have inadequate resources or regulation to limit improper disposal. In some places solid waste is intentionally dumped into bodies of water. Land pollution can also become water pollution if the trash or other debris is carried by animals, wind, or rainfall to bodies of water. Significant amounts of solid waste pollution in inland bodies of water can also eventually make their way to the ocean. Solid waste pollution is unsightly and damaging to the health of aquatic ecosystems and can harm wildlife directly. Many solid wastes, such as plastics and electronic waste, break down and leach harmful chemicals into the water, making them a source of toxic or hazardous waste.

Of growing concern for aquatic environments is plastic pollution . Since the ocean is downstream from nearly every terrestrial location, it is the receiving body for much of the plastic waste generated on land. Several million tons of debris end up in the world’s oceans every year, and much of it is improperly discarded plastic litter. Plastic pollution can be broken down by waves and ultraviolet radiation into smaller pieces known as microplastics , which are less than 5 mm (0.2 inch) in length and are not biodegradable. Primary microplastics, such as microbeads in personal care products and plastic fibers in synthetic textiles (e.g., nylon ), also enter the environment directly, through any of various channels—for example, from wastewater treatment systems , from household laundry, or from unintentional spills during manufacturing or transport. Alarmingly, a number of studies of both freshwater and marine locations have found microplastics in every aquatic organism tested. These tiny plastics are suspected of working their way up the marine food chains , from zooplankton and small fish to large marine predators, and have been found in seafood. Microplastics have also been detected in drinking water. Their health effects are unknown.

Waste is considered toxic if it is poisonous , radioactive , explosive , carcinogenic (causing cancer ), mutagenic (causing damage to chromosomes ), teratogenic (causing birth defects), or bioaccumulative (that is, increasing in concentration at the higher ends of food chains). Sources of toxic chemicals include improperly disposed wastewater from industrial plants and chemical process facilities ( lead , mercury , chromium ) as well as surface runoff containing pesticides used on agricultural areas and suburban lawns ( chlordane , dieldrin , heptachlor). (For a more-detailed treatment of toxic chemicals, see poison and toxic waste .)

Sediment (e.g., silt ) resulting from soil erosion or construction activity can be carried into water bodies by surface runoff . Suspended sediment interferes with the penetration of sunlight and upsets the ecological balance of a body of water. Also, it can disrupt the reproductive cycles of fish and other forms of life , and when it settles out of suspension it can smother bottom-dwelling organisms.

Heat is considered to be a water pollutant because it decreases the capacity of water to hold dissolved oxygen in solution, and it increases the rate of metabolism of fish. Valuable species of game fish (e.g., trout ) cannot survive in water with very low levels of dissolved oxygen . A major source of heat is the practice of discharging cooling water from power plants into rivers; the discharged water may be as much as 15 °C (27 °F) warmer than the naturally occurring water. The rise in water temperatures because of global warming can also be considered a form of thermal pollution.

Petroleum ( oil ) pollution occurs when oil from roads and parking lots is carried in surface runoff into water bodies. Accidental oil spills are also a source of oil pollution—as in the devastating spills from the tanker Exxon Valdez (which released more than 260,000 barrels in Alaska’s Prince William Sound in 1989) and from the Deepwater Horizon oil rig (which released more than 4 million barrels of oil into the Gulf of Mexico in 2010). Oil slicks eventually move toward shore, harming aquatic life and damaging recreation areas.

Groundwater —water contained in underground geologic formations called aquifers —is a source of drinking water for many people. For example, about half the people in the United States depend on groundwater for their domestic water supply . Although groundwater may appear crystal clear (due to the natural filtration that occurs as it flows slowly through layers of soil ), it may still be polluted by dissolved chemicals and by bacteria and viruses . Sources of chemical contaminants include poorly designed or poorly maintained subsurface sewage-disposal systems (e.g., septic tanks ), industrial wastes disposed of in improperly lined or unlined landfills or lagoons , leachates from unlined municipal refuse landfills, mining and petroleum production, and leaking underground storage tanks below gasoline service stations. In coastal areas, increasing withdrawal of groundwater (due to urbanization and industrialization) can cause saltwater intrusion: as the water table drops, seawater is drawn into wells.

Although estuaries and oceans contain vast volumes of water, their natural capacity to absorb pollutants is limited. Contamination from sewage outfall pipes, from dumping of sludge or other wastes, and from oil spills can harm marine life, especially microscopic phytoplankton that serve as food for larger aquatic organisms. Sometimes, unsightly and dangerous waste materials can be washed back to shore, littering beaches with hazardous debris. In oceans alone, annual pollution from all types of plastics was estimated to be between 4.8 million and 12.7 million tonnes (between 5.3 million and 14 million tons) in the early 21st century, and floating plastic waste had accumulated in Earth’s five subtropical gyres, which cover 40 percent of the world’s oceans.

Another ocean pollution problem is the seasonal formation of “ dead zones” (i.e., hypoxic areas, where dissolved oxygen levels drop so low that most higher forms of aquatic life vanish) in certain coastal areas. The cause is nutrient enrichment from dispersed agricultural runoff and concomitant algal blooms. Dead zones occur worldwide; one of the largest of these (sometimes as large as 22,730 square km [8,776 square miles]) forms annually in the Gulf of Mexico , beginning at the Mississippi River delta.

Although pure water is rarely found in nature (because of the strong tendency of water to dissolve other substances), the characterization of water quality (i.e., clean or polluted) is a function of the intended use of the water. For example, water that is clean enough for swimming and fishing may not be clean enough for drinking and cooking. Water quality standards (limits on the amount of impurities allowed in water intended for a particular use) provide a legal framework for the prevention of water pollution of all types.

There are several types of water quality standards. Stream standards are those that classify streams, rivers , and lakes on the basis of their maximum beneficial use; they set allowable levels of specific substances or qualities (e.g., dissolved oxygen , turbidity, pH) allowed in those bodies of water, based on their given classification. Effluent (water outflow) standards set specific limits on the levels of contaminants (e.g., biochemical oxygen demand , suspended solids, nitrogen ) allowed in the final discharges from wastewater-treatment plants. Drinking-water standards include limits on the levels of specific contaminants allowed in potable water delivered to homes for domestic use. In the United States , the Clean Water Act and its amendments regulate water quality and set minimum standards for waste discharges for each industry as well as regulations for specific problems such as toxic chemicals and oil spills . In the European Union , water quality is governed by the Water Framework Directive, the Drinking Water Directive, and other laws . ( See also wastewater treatment .)

Water Pollution Essay

Water is a necessity for all life forms present on this planet. Animals need water to quench their thirst, plants need water to draw nutrients from the soil and keep nourished, and people need water for a variety of activities like drinking, cooking, cleaning, and washing, to mention a few. Even though water is so important to us, there are many practices which humans follow which are making fresh water scarce. Water pollution is when the substances that make the water contaminate the sources of the water. Chemicals, garbage, bacteria, and parasites are examples of pollutants. Eventually, every kind of pollution finds its way into the water. Here are a few sample essays on "water pollution".

100 Words Essay On Water Pollution

Water is necessary for our survival and to live a healthy and happy life. Everyone is familiar with the picture of people living in misery in nations without access to water, such as Africa. It's time for everyone to wake up and understand how important water conservation is. Human species couldn't survive in a world without water. All plants and animals fall under this same category. In fact, without water, the entire planet will suffer. Water bodies, including lakes, rivers, seas, oceans, and groundwater, have all been contaminated. Water bodies become contaminated when waste from homes, factories, and other buildings enters them.

As stated, water pollution is a severe issue that can be catastrophic for all living beings, including humans, plants and animals. We must comprehend the value of water in our life and the need to preserve it. There are numerous easy ways to prevent water waste, including taking shorter showers, watering plants with RO waste, cleaning cars with a wet cloth rather than a hose, etc. To gather rainwater, we must also employ the rainwater harvesting technique. In this way, we can conserve water.

200 Words Essay On Water Pollution

On Earth, water is abundant. Both above and below the surface of the Earth, it exists. Rivers, ponds, seas, and oceans are just a few of the water bodies found on the surface of the Earth. Even though our world can replenish its own water, over time, we are destroying and abusing the abundance of water present. Even though 70% of the surface of the Earth is covered by water and 30% by land, the rapidly expanding water contamination impacts marine life and humans. Everyone is beginning to be concerned about the uneven distribution of water on Earth and the rising demand for it due to the growing population.

Contaminants | City sewage and commercial waste discharge are two of the most harmful factors contributing to water contamination. Contaminants that reach the water supply through soils or groundwater systems, as well as through rain, are examples of indirect sources of water pollution. The chemical contaminants are more dangerous and challenging to remove from a water body than the visible impurities, which can be easily eliminated by physical cleaning or filtering. Water's characteristics are altered when chemicals are added, making it dangerous to use and perhaps lethal.

Solution | To prevent water pollution, there are several steps we, as citizens and the government, can take. Since water efficiency and conservation are essential elements of sustainable water management, enhancing water infrastructure must be prioritised. Intelligent irrigation systems and solar desalination are excellent examples of clean technology for managing and conserving water.

Also, Rainwater harvesting and reusing is an excellent method to prevent water pollution. Groundwater and other natural water sources can be under less stress because of reclaimed wastewater and rainwater gathering. It is common knowledge that one way to avoid water scarcity is through groundwater recharge, which enables water to move from surface water to groundwater.

500 Words Essay On Water Pollution

Although water is essential to every living thing on the planet, Humans still indulge in activities that make water a scarce resource. When a body of water—such as a river, lake, ocean, etc.—becomes polluted due to human activity or a natural source, the term "water pollution" is used. Water contamination is now a significant environmental issue that requires responsible management. Water contamination is caused primarily due to human activities such as urbanisation, industrialisation, deforestation, trash dumping, and landfills.

Causes Of Water Pollution

On the earth, fresh water is extremely limited, and pollution is making it much more so. We lose millions of litres of fresh water each year to industrial pollution and other forms of pollution. Pollutants include both large and small items of obvious trash as well as intangible, dangerous, and deadly compounds.

Many factories are located close to water sources, and they transport their waste there using fresh water. This industrial waste is poisonous by nature and endangers both the flora and fauna's health. People close to polluted water bodies have been seen to have significant skin, respiratory, and occasionally even life-threatening health illnesses.

Urban garbage and sewage are other significant contributors to water contamination. Each household generates tons of waste annually, including plastic, wood, chemicals, and other substances. This trash reaches our aquatic bodies, such as rivers, lakes, and streams, and pollutes them without an effective waste disposal system.

How To Manage Water Pollution

By educating people about the causes and impacts of water pollution on life and the environment, water pollution might be significantly reduced. People need to participate in cleanup initiatives when a community or organisation cleans up the waterways every week or at least once a month. To completely eradicate water contamination, strict legislation must also be created and adequately enforced. Strict oversight will increase accountability and may deter individuals and groups from polluting. We should all be aware of our daily activities and take measures to help the world become a better place for future generations.

Real-Life Experience

I have always loved my town as it has many lakes, rivers, and forests. One day, as I walked along the river that ran through my village, I couldn't help but notice the strange colours swirling in the water. It wasn't the crystal clear blue that I was used to seeing. Instead, the water was a murky brown, and there was a strong, foul smell emitting from it. Curious, I decided to investigate further. I made my way down to the riverbank and peered into the water, trying to get a closer look at what was causing the strange colours and smells. As I looked more closely, I saw that strange foam bubbles were floating on the surface of the water.

Suddenly, I heard a noise behind me and turned to see a group of people rushing towards the river. They were shouting and waving their arms, and I could see the panic on their faces. I quickly realised that something was very wrong. As the group reached the river, they saw that the water was teeming with dead fish floating belly up on the surface. The smell of rotten fish was overpowering, and it was clear that something had seriously polluted the river.

After a thorough investigation, it was determined that a local factory had been releasing toxic chemicals into the river, causing widespread pollution and destruction of the ecosystem. I was shocked and saddened by this discovery, and I knew it would take a lot of work to clean up the river and restore it to its former glory.

Water Pollution Essay 1 (100 Words)

Water Pollution refers to the contamination of water bodies and underground resources of water by any of the several human activities or natural causes. Human activities like, urbanization, industrialization, deforestation, waste disposal, landfills are primarily responsible for water pollution.

Some of the natural causes responsible for water pollution are volcanoes and debris from floods. Another natural cause of water pollution is algae bloom. The term “algae” is used to refer to a large and diverse group of photosynthetic organisms. Algae bloom means an increase in the population of algae in a water body, consequently resulting in its discoloration and contamination.

Water Pollution Essay 2 (150 Words)

The term “Water Pollution” is used when a water body like a river, lake, ocean, etc is polluted due to human activity or a natural cause. Today, water pollution has become a major environmental concern and needs to be responsibly dealt with.

Fresh water is very scarce on the planet and pollution is making it even scarcer. Every year we lose millions of liters 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 hazardous and difficult to remove. Chemicals get mixed into water and change its properties, making it harmful to use and life-threatening.

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.

Water Pollution Essay 3 (200 Words)

Water Pollution is a matter of environmental concern as well as life and health of all living species. For a population of 7.8 billion growing at a rate of 82 million every year we have very little freshwater.

Only 2.5% of all the water available on earth is freshwater that we use for our daily needs. But, human’s desire to expand boundaries and explore commercial avenues have put stress on our freshwater resources, making them polluted as never before.

Many industries are set up near water bodies and use freshwater to carry industrial waste to the nearby water bodies. This industrial waste is toxic in nature and poses a health hazard to the flora and fauna. People in the settlements in the vicinity of polluted water bodies are observed to be suffering from serious skin, respiratory and sometimes even life-threatening other ailments.

Other the main cause of water pollution is urban waste and sewage. Every household produces tons of waste annually, consisting of plastic, wood, chemicals, and other compounds. In the absence of a proper waste disposal mechanism, this waste reaches our water bodies like rivers, lakes, streams and pollutes them. Water pollution must be prevented if we want the earth to be green, healthy and filled with life.

Water Pollution Essay 4 (250 Words)

Water is an essential resource for life on earth. Without water, or to be more specific, without clean and safe water, life on earth would be unimaginable. You may think that we still have plenty of water with it constituting 97.5% of the total volume of earth. But, there is a catch – 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, that is, only 2.5% is freshwater what we use. Moreover, only 0.3% of that 2.5% is the water found on the surface of the earth. To be more specific, the total volume of water on earth is 1,386,000,000 Km 3 , out of which only 10,633,450 Km 3 is freshwater. Leaving very less freshwater for a population of 7.8 billion as on December 2019 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 centuries 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, within a couple of decades we could face an acute water crisis. Then we might be left with no option but only to regret what we have done. There is still time and things can be normalized if we take action today. Whether it is an individual action or a collective one, an action to conserve water and prevent its pollution is the need of the day.

Water Pollution Essay 5 (300 Words)

Introduction

Water Pollution occurs when external pollutants enter the otherwise clean and safe natural water resources. Due to the growing human intervention and expansion of urban settlements, water pollution has become a painful reality today.

Water Pollution Sources

The sources of water pollution are many and almost all of them are generated due to human activities. Industries emit millions of gallons of toxic smoke and material waste which is left directly into the air, water bodies and natural resources. Most of such waste from the industries are left directly into the water bodies without any kind of treatment. Most of the industrial waste is toxic in nature and in turn, increases the toxicity of the water it reaches.

Also, the domestic waste that is generated every day in the millions of households around the world contains waste plastic materials, chemicals, oils, metals, etc. Most of the households lack a proper waste disposal mechanism and mostly the waste is directly dumped into the environment.

How to Stop Water Pollution

Water pollution could be prevented considerably by making people aware of its causes and its effects on life and the planet. People must take part in cleaning campaigns wherein a group or community takes up the task of cleaning the water bodies every weekend or at least once in a month.

Moreover, strict laws need to be formed and strictly implemented with the objective of eliminating water pollution. Strict monitoring could prevent people and organizations from polluting and will improve accountability as well.

Water pollution today has become a topic of hot debate and concern for environmentalists and scientists. It threatens the future of all the living species on the planet earth. Water is an essential commodity to live added by the fact that only 2% of the water on earth is fresh water that we use. We can’t afford to pollute it further and must take steps for the reversal of the damage that we have already done.

Water Pollution Essay 6 (350 Words)

Water Pollution refers to the introduction of pollutants into our water bodies. These pollutants are primarily generated by human-induced activities and pose a threat to our natural water resources.

Water Pollution Prevention

There are several things one could do to prevent water pollution. Some of them are simple enough to be taken by an individual while some require collective efforts. However, the efforts need to be repeatedly done in order to preserve our natural water resources. Some of the implementable ways to prevent water pollution are given below-

1) Keep your drain free of Contaminants and Chemicals.

An average household generates all kinds of waste including chemicals, disposed medicines, and other hazardous compounds. We must take care while disposing of our household waste and ensure that any such waste didn’t reach the sewage system.

2) Prevent use of Polythene

Polythene bags are widely used today in every household. They are light, could carry heavyweight, and easy to store. But polythene bags constitute a major threat to water resources. The polythene that we dispose of our houses, finds its way into the water bodies. Being non-biodegradable, it just lays there, polluting water and making it toxic.

3) Conserve Water

Always try to conserve water while doing your daily activities, whether it’s cooking, shaving, bathing, gardening or cleaning, etc.  Water conservation can also be achieved by repairing all the faulty taps in your house and locality as well.

4) Reuse and Recycle

Much of the waste that we generate in houses could be reused and recycled if only we make a little effort for it. Wastes like automobile oil are disposed into the drain and easily reach into rivers and streams. This is really hazardous to the purity of water and also to the life of organisms that live in water. On the other hand, automobile oil can be reused for several other lubrication purposes.

Water pollution today has become a cause of great concern for human health as well as the environment. Water is an essential commodity without which life can’t be imagined. It is the duty of all to take steps for keeping water pollution-free and also to conserve it, for a healthy future of the planet.

Water Pollution Essay 7 (400 Words)

Water Pollution refers to the contamination of water bodies like rivers, lakes, ponds and oceans. It is caused when the pollutants generated by human activities like industrialization, urban waste, littering, etc., enter our water bodies and pollute them.

Types of Water Pollution

As water comes from many sources, there are many types of water pollution. The most common types of water pollution are described below.

1) Agricultural/Nutrients Pollution

Some of the waste water and agricultural waste contain high nutrients levels. These nutrient-rich contaminants cause algae growth, making the water unfit for drinking and other purposes. Algae use the oxygen content in water making oxygen scarce for other organisms, resulting in their death.

2) Sewage and Waste Water

Sewage and waste water from urban settlements is rich in various soluble and non-soluble impurities like mercury, plastic, rotten food, debris, chemicals etc. When these pollutants reach water bodies, some of them float over the surface while some sink at the bottom. The soluble impurities change the composition of water as well. This is a dangerous situation for all the living organisms in the water body.

3) Oxygen Depletion

Any water body contains several microorganisms including aerobic and anaerobic organisms. When the biodegradable waste reaches into the water bodies and decays, it encourages the growth of more microorganisms, consequently using more oxygen, in turn, depleting the oxygen level.

4) Pollution of Ground Water

Use of chemical pesticides and fertilizers pollute the groundwater resources. The chemicals get mixed with soil and are soaked into the ground with rain, reaching the underground water reserve. This contaminated water reaches our wells and other sources of water, making its consumption harmful.

Prevention of Water Pollution

Water Pollution can be prevented by taking these simple steps –

• Don’t pour down fat or oil in your kitchen sink.
• Avoid improper disposing of harmful chemicals and other contaminants.
• Never let unused or expired medicines reach the house drainage system.
• Segregate 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.

Water pollution is a growing environmental concern 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.

Water Pollution Essay 8 (500 Words)

Water Pollution refers to the contamination of water bodies, primarily due to human activities. Water bodies include lakes, rivers, ponds, oceans and underground water resources. Water Pollution occurs 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.

Causes of Water Pollution

Water is an essential natural resource and very useful for life on earth. Causes of water pollution are many and always include human activities. The various causes of water pollution are given below-

1) Urban Sewage

The sewage from urban settlements is usually treated with chemicals and then released into the water bodies after mixing with fresh water. Most of the time, the sewage is not treated and is left into the water bodies. It contains harmful, bacteria and pathogens, which is extremely harmful to aquatic life and to humans as well.

2) Industrial Waste

Large amount of toxic waste is produced by the industries. 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. Due to the absence of a proper waste management system, many industries still dump harmful waste in natural water resources.

3) Garbage Dumping

Common household garbage contains plastic, food, wood, paper, rubber, aluminum, etc. 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 as well as the life of flora and fauna over the adjoining lands.

4) Oil Spills

Oil is non-soluble in water and being lighter in density, floats over it. Though the oil spills have been considerably reduced in the past decades, the incidents of oil spills still happen. For instance, in 2018, there were 137 oil spills in the United States alone. Out of 137 spills, 65 were reported as the maximum potential spills, releasing gallons of oil into the water.

5) Landfills Leakage

Landfills are the huge piles of garbage usually found on the outskirts of a city or urban settlement. The garbage from the landfills leaks into the water bodies with rain or reaches with the wind, resulting in their contamination. They contain a large amount of several contaminants harmful for aquatic life.

Effects of Water Pollution

The most immediate effect of water pollution is on the organisms that live in water. Moreover, it is also harmful to the surrounding plants, animals and humans those use or consume water in some form or the other.

Chemical pollutants are most harmful in this regard as they are difficult to separate physically and alter the properties of water. They get mixed with the water alter its chemical properties, making it harmful to consume or use.

Use of contaminated water causes several serious diseases in humans like – diarrhea, cholera, typhoid, dysentery, etc and could be life-threatening.

Water Pollution today has become a serious issue that concerns the health of the planet and its inhabitants. Water is a very useful resource, much needed for drinking and other essential activities by humans and animals alike. If the already scarce freshwater is made contaminated then the chances of life on the planet are considerably reduced. To save life on earth we must first save the water by keeping our water bodies clean.

Water Pollution Essay in English

The addition of harmful and disadvantageous substance sot the natural reserves and resources of water is termed as water pollution. It can be in the form of flowing water like rivers, streams, oceans and seas or stagnant water bodies like lakes etc. Even the underground reserves of groundwater are affected by the percolation of pollutants either through soil or surface runoff. 

Among various causes and sources of water pollution, the major one is industries who release their untreated or partially treated refuse called as effluents into the water bodies as a dump or dispose of. This water may, in turn, reach seas and oceans and spread to a wider area than initially assumed.

The next big source is the domestic habitation near the river banks or coastal areas etc. The refuse and waste from these houses are often dumped into the adjoining water body. The dumping of dead bodies (as pr certain religions) or ashes also play a huge part in contamination of natural waters. 

There are also activities like bathing, washing clothes etc which are performed in or near rivers further adding to their pollution. Even transportation though waters like ships etc often cause spilling and accumulation of waste which can be catastrophic for the water and its quality.

There has to the development of infrastructure for holistic treatment and purification of water and also wastewater (from various sources). Better methods of waste disposal especially industrial waste, radioactive waste etc have to be developed leveraging newer and environmentally sustainable technologies.

Apart from these, there has to be an overall focus on developing habits of conservation and reuse of water resources for them to be enjoyed for a long time to come.

Essay 1 (250 Words) – Meaning, Causes and Preventive Measures of Water Pollution

Introduction

Water pollution is referred to as the contamination of water by several human activities. When toxic compounds get introduced in water, they render it harmful to health and dangerous for life.

Why is Water Pollution a Problem?

Do you know that around 80% of the world’s wastewater produced annually is dumped directly into our water bodies, without even get treated? Such a high level of contamination of natural water bodies compromises the health of humans as well as other land and aquatic species. Unclean and contaminated water claims more lives annually than war and other diseases.

Various Causes of Water Pollution

There are various causes of water pollution; most of them are human-generated. Some of the significant causes of water pollution are –

• Dumping industrial waste
• Urban sewage
• Landfill rain wash
• Mining activities
• Fossil fuel production and burning
• Leaked sewer lines
• Littering at public places
• Improper waste disposal

Preventive Measures

• Ensure proper waste disposal at home.
• Ensure that no fat or oil reaches the drain.
• Avoid the dumping of plastic.
• Avoid the use of chemical fertilizers and pesticides, especially during the rains.
• Don’t improperly dump medicines and other chemicals.
• Clean your nearest water reserve from time to time, with help of others.

Water pollution is a major threat to the environment as well as to the life of species. It affects everyone and is severely damaging the ecological balance. It is extremely necessary that we take the necessary steps to prevent it.

Essay 2 (400 Words) – Water Pollution: A Global Concern

Water pollution occurs when contaminants from different sources get into the water bodies. Such pollutants contaminate the rivers, streams, ponds, lakes, and also groundwater, risking the life and health of humans as well as other living species.

Water Pollution – A Global Concern

Water pollution has become an issue of global concern as it is beginning to affect more lives. Incessant and indiscriminate industrialization and other commercial activities have led to the exploitation of natural resources and also the pollution of water bodies.

Water pollution poses the greatest health hazard to humans and other living organisms. Millions of people from across the globe die due to water-borne diseases. They don’t have access to clean drinking water and are forced to consume dangerously contaminated water.

A contaminated water body is unable to support life. All the land species as well as the aquatic life suffers due to water pollution. Water pollution has resulted in the depletion of aquatic life. There have been a record number of declines in the population of fish, tortoise, whale, coral reefs, etc.

Water Pollution Facts

Below given are some of the important facts about water pollution –

• Around 70% of industrial waste produced is dumped into water bodies.
• Domestic sewage accounts for around 80% of water pollution.
• Consumption of contaminated water causes serious ailments like cholera and diarrhea.
• Billions of pounds of plastic garbage are released into the oceans annually.
• Water pollution causes the death of around 15 million children globally.
• 2.5 billion People don’t have access to clean drinking water.
• Asia has the largest number of polluted rivers than any other continent.
• Plastic is one of the main constituents causing the death of several aquatic species.

Prevention of Water Pollution

Water pollution can be considerably prevented by reducing littering and adopting proper waste disposal methods. This ensures that no waste reaches the atmosphere and hence water bodies. Also, there should be a strict regulatory mechanism to control industrial waste or to recycle it. Moreover, plastic use in any form should be banned mainly near the water bodies, oceans, and other tourist spots.

Water pollution is causing more deaths globally than any other factor. This is high time that the world reacts to the situation and gets rid of the menace of water pollution by taking necessary preventive measures. The problem will only be solved if we act otherwise, there would be no clean water left for us to consume.

Essay 3 (500 – 600 Words) – Water Pollution: Causes and Effects

Water pollution occurs when the water bodies get contaminated mainly due to human activities. Water bodies like rivers, lakes and streams are continuously being contaminated by industrial, and sewage waste, released indiscriminately into it.

Causes of Water Pollution

There are many causes of water pollution but almost all of them are generated primarily due to human activities. Some of the main causes of water pollution as listed below.

• Industrial Waste

Industries from across the world emit toxic waste into the nearby water bodies. This waste contains all types of toxic compounds like mercury, lead, all kinds of acids and bases, hydrocarbons, etc. It contains both soluble as well as insoluble impurities.

Sewage water from human dwellings also contains all kinds of soluble and insoluble contaminants that pollute the water bodies. Many cities lack having a proper waste disposal management system, causing indiscriminate pollution of the water bodies.

Littering is another significant source of water pollution. Plastic and other waste that visiting tourists litter gets carried into the water bodies by wind and rain. Usually, these pollutants are plastic in the form of food packets, plastic bottles, etc.

• Chemical Fertilizers and Pesticides

The use of chemical fertilizers and pesticides in the agriculture industry is also the main cause of water pollution. Harmful chemicals seep into groundwater or get carried into the nearest water body by rain.

The oil spill is also a major cause of oceanic water pollution. Oceans have become an important route of transportation. This often results in accidental oil spills oversea. Oil doesn’t dissolve in water and just float on the surface, blocking oxygen, thereby harming the aquatic life.

• Algae Blooms

Algae blooms are organisms that severely degrade the oxygen level of the water bodies. This in turn kills a number of marine lives and degrades the quality of aquatic life.

Effects of Water Pollution

Water pollution affects human health as well as the whole ecological balance of the planet. All in all, it affects each and every living organism that inhabits the planet. Below is a description of several effects of water pollution.

• On Human Health

Water pollution is a great factor that affects human health. Millions of people from around the globe are exposed to some kind of contaminated water that seriously degrades their health. Studies show that around one billion people across the globe don’t have access to clean drinking water. Around half a million people every year die due to consuming contaminated water or water-related illnesses.

• Species Depletion

Water pollution at different levels has caused severe impacts on other living species as well. While humans can clean water and consume, other living species don’t have that privilege. They rely on natural water sources as it is. If the water is polluted and gets consumed by animals, it harms their health, often resulting in their death.

• Marine Life

Water pollution is the main cause of concern for marine life. When water gets polluted many aquatic species get affected. Water pollution has been the reason behind the declining numbers of fish, tortoise, whale, and several other aquatic species.

• Environmental Degradation

Water pollution seriously degrades the overall quality of the environment. Everything in the environment is linked to each other. If the quality of water degrades so also degrades the quality of the environment. It consequently results in climatic variation, acid rain, and other effects.

Water pollution is one of the main environmental concerns today. It impacts not only human life but also the ecological balance as a whole. It also impacts the overall health of the environment.

Below we have provided Water Pollution Essay in English, suitable for class 3, 4, 5, 6, 7, 8, 9 & 10. This essay is drafted in simple and easy words.

Water is undoubtedly one of the essential resources on our planet. It is vital for the survival of all living organisms. Water takes over two-thirds of the Earth’s surface. It is a priceless commodity that has been contaminated and depleted to a critical level with time. The addition of harmful foreign substances into water bodies is known as water pollution. These water bodies can be in the form of aquifers, rivers, lakes, ponds, seas, groundwater, streams, waterfalls, and oceans. Human activities are the prime reason for the adulteration of water bodies.

Types of Water Pollution

Water pollution can be of three kinds – groundwater pollution’s, surface water pollution, and marine pollution.

The contamination of groundwater is known as groundwater pollution. Industrial effluents, dirty water from drains and sewage, which flow on the land surface, seep down the soil and mix with the groundwater. Surface water pollution includes contamination of open water bodies (like rivers, lakes, and oceans) present on Earth’s surface. Lack of proper sanitation and uncontrollable discharge are the major contributors.

Marine pollution involves large water bodies. Wastewater discharges in the river make their way to the seas and oceans, thus causing pollution. Aquatic species become exposed to hazardous chemicals. Food chains get disrupted. Oxygen content in the water bodies is reduced. Marine life is adversely affected as a result. These polluted water bodies become the hub for microbes and spread epidemics like cholera, typhoid, hepatitis, and diarrhoea.

Causes of Water Pollution

Water tends to dissolve almost everything. It is known as the universal solvent. This feature enables it to dissolve toxic substances. These toxicities arise from factories, refineries, waste disposal sites, acid rains, detergents, domestic waste, etc. Some of the major causes of water pollution are:

• Sewage: Every day, tons of waste matter generated from farmlands, commercial sites and households are dumped into the lakes and rivers. These wastes which remain untreated contain harmful chemicals that can be poisonous to plants, animals, and humans.
• Industrial Effluents: Industrial waste largely contributes to the adulteration of water bodies. Direct disposal of these wastes has disastrous effects on the ecosystem. Chemical effluents from tanning industries contain poisonous compounds, volatile matter, and heavy metals. This water then mixes with the river and contaminates the underground water table.
• Eutrophication: It is the process that occurs when large amounts of nutrients in the water bodies result in the formation and growth of algae on the surface of the water. Bacteria feed on these algae. Hence, aquatic organisms like fishes and plants get depleted of oxygen. Their habitat is destroyed, and the quality of water is critically reduced.
• Oil Spills: Leakages from ships and tankers result in oil spills. This is one of the most dangerous modes of water pollution. When the oil gets spilt, it forms a layer over the water surface. This layer prevents the penetration of oxygen, which is essential for the survival of marine plants and animals.
• Affected River Banks: Lack of sanitation measures in the villages has resulted in defecation in open areas (especially near river banks). Washing clothes and cattle in the lakes is a common practice. Solid waste accumulation is not a rare sight. Litters composed of plastics, glasses, Styrofoam, etc., do not decompose well and stay in the water for years.
• Indirect Sources: These are the pollutants that indirectly lead to water pollution. They can be chemical dumps, septic tanks, pesticides, hazardous wastes, radioactive substances, etc. Radioactive wastes generated from atomic power plants and other medical procedures are dangerous.

Prevention of Water Pollution

Besides predominantly affecting our health, water pollution can have disastrous effects on our ecosystem. Toxicant pass through the affected aquatic species to us humans. The food chain is badly influenced by it. Prevention of water pollution is essential. Conservation of water must be the first step. Preventive measures include sewage water treatment, using environment-friendly products, reduction in plastic consumption, proper disposal of chemical liquids, solid waste management, and less use of pesticides.

Apart from that, drains must be cleaned more often. The implementation of proper sanitary measures by the government in the villages is a great step. Mass awareness through media and entertainment can help sensitize people about the issue. Educating people, especially in rural areas, can ensure a positive outcome. Enforcement of appropriate laws for Industries and other production sectors can prove beneficial. Natural reserves of water must be safeguarded, and a balance must be maintained in our diversified environment.

250 Words Essay on Water Pollution

Water pollution is an escalating problem with far-reaching implications for the health of both ecosystems and human populations. It involves the contamination of water bodies such as rivers, oceans, lakes, and groundwater due to human activities, leading to a deterioration in water quality.

The Causes of Water Pollution

Water pollution arises from various sources, including industrial waste, agricultural runoff, and domestic sewage. Industrial waste often contains harmful chemicals and heavy metals, while agricultural runoff is replete with pesticides and fertilizers. Domestic sewage, on the other hand, is a source of pathogens and organic pollutants.

Impacts of Water Pollution

The effects of water pollution are manifold and severe. It disrupts ecosystems, leading to the loss of biodiversity and the death of aquatic species. Moreover, it poses significant health risks to humans, causing diseases like cholera and dysentery. Polluted water also affects agriculture, reducing crop yield and quality.

Solutions to Water Pollution

Addressing water pollution requires a multi-pronged approach. Legislation and enforcement are necessary to regulate waste discharge from industries and agriculture. Technological solutions, such as wastewater treatment and recycling, can also play a pivotal role. Additionally, public awareness and education about water conservation and pollution prevention are essential.

500 Words Essay on Water Pollution

Water pollution is an escalating global concern that threatens the health of our planet and its inhabitants. It refers to the contamination of water bodies such as rivers, oceans, lakes, and groundwater, caused by human activities. This pollution affects not only the quality of water but also the broader ecosystem, impacting both aquatic and terrestrial life forms.

Water pollution can be attributed to a myriad of sources, broadly categorized into point sources and non-point sources. Point sources relate to pollutants directly discharged into water bodies from identifiable locations such as factories, sewage treatment plants, and oil spills. Non-point sources, on the other hand, are diffuse and harder to control, including agricultural runoff, urban runoff, and atmospheric deposition.

The Consequences of Water Pollution

Water pollution also poses a significant threat to public health. Contaminated water is a breeding ground for waterborne diseases such as cholera, dysentery, and typhoid. With over 780 million people lacking access to clean water, the health impact is substantial and disproportionately affects vulnerable populations.

Addressing Water Pollution

Public awareness and education are also key in addressing this issue. By understanding the causes and effects of water pollution, individuals can make informed decisions and contribute to the solution, whether through responsible consumption, waste disposal, or advocacy.

Water pollution is a pressing issue that requires immediate and sustained attention. While the situation is dire, it is not insurmountable. Through collective action, stringent regulations, technological advancements, and increased awareness, we can mitigate water pollution and safeguard our water resources for future generations. The fight against water pollution is not just an environmental obligation, but also a prerequisite for our survival and well-being.
