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.

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.

What is Water Pollution?

When many pollutants such as garbage, chemicals, bacteria, household waste, industrial waste, etc get mixed in the water resources and make the water unfit for cooking, drinking, cleaning, etc. it is known as water pollution. Water pollution damages the quality of water. lakes, water streams, rivers, etc may become polluted and eventually they will pollute the oceans. All this will directly or indirectly affect the lives of us humans and the animals deteriorating our health.

Essay on Water Pollution in 200 Words

Water is plentiful on Earth, present both above and beneath its surface. A variety of water bodies, such as rivers, ponds, seas, and oceans, can be found on the planet’s surface. Despite Earth’s ability to naturally replenish its water, we are gradually depleting and mishandling this abundant resource. 

Although water covers 71% of the Earth’s surface and land constitutes the remaining 29%, the rapid expansion of water pollution is impacting both marine life and humans. 

Contaminants 

Water pollution stems significantly from city sewage and industrial waste discharge. Indirect sources of water pollution include contaminants that reach water supplies via soil, groundwater systems, and precipitation. 

Chemical pollutants pose a greater challenge in terms of removal compared to visible impurities, which can be filtered out through physical cleaning. The addition of chemicals alters water’s properties, rendering it unsafe and potentially lethal for consumption.

Solution 

Prioritizing water infrastructure enhancement is vital for sustainable water management, with a focus on water efficiency and conservation. 

Furthermore, rainwater harvesting and reuse serve as effective strategies to curb water pollution. Reclaimed wastewater and collected rainwater alleviate stress on groundwater and other natural water sources. 

Groundwater recharge, which transfers water from surface sources to groundwater, is a well-known approach to mitigate water scarcity. These measures collectively contribute to safeguarding the planet’s water resources for present and future generations.

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.

Real-Life Encounter

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.

Water Pollution Causes, Effects and Solutions

Introduction, causes of water pollution, effects of water pollution, solutions to water pollution, reference list.

Rivers are common sources of water in the world. Water is useful in various ways both domestically and in industries. It is imperative that such water remains clean and safe and free from any pollution. Unfortunately, water pollution takes place in various water bodies all over the world. This essay seeks to examine the concept of water pollution, its causes, effects, and solutions to water pollution.

Water pollution refers to dirtying of water resulting in a chemical, physical or biological alteration in the condition of water making such water harmful to anyone who utilizes it. In other words, pollution makes water unfit for consumption (Go Green Academy, 2013). There are various causes of water pollution. Disposing solid waste in water sources is the main cause of water pollution (Go Green Academy, 2013). Most of these wastes are made of plastic, which by nature, is non-biodegradable. Plastics take over four hundred years to decompose in water and as such, they move in different places before they finally decompose.

Effluence from industries and factories cause water pollution (Go Green Academy, 2013). Coffee factories use fresh water to transport waste to rivers. Effluence from industrial plants adds pollutants like lead and mercury into rivers. Oil spills from ships on transit also cause water pollution. Oil is indissoluble in water and consequently forms thick patches on the water surface making it hard for organisms in such a water body to survive. Overall, such contaminated water destroys an ecosystem (Go Green Academy, 2013).

Sewerage disposal from households and commercial houses cause water pollution. In some places, sewage can be treated or recycled but in most places, such waste finds a way into rivers. Due to chemical substances used in maintaining hygiene in washrooms, effluence from such places is destructive to water sources into which it flows (Go Green Academy, 2013). Cauterizing of fossil fuels leads to building up of acidic particles in the air, which in turn leads to acidic rains falling on water bodies (Go Green Academy, 2013).

Groundwater polluted through the use of chemicals in farming causes destruction to plants, which in turn affect human beings and animals that feed on them (Go Green Academy, 2013). Secondly, polluted water causes skin rashes and even cancer to swimmers. In addition, such water can cause reproductive difficulties and typhoid fever, which if untreated, leads to death. Water pollution leads to flooding when solid wastes accumulate to very high levels (Go Green Academy, 2013).

Global warming leads to increased water temperatures and this leads to the destruction of aquatic plants. Coral reefs, for instance, suffer destruction because warm water has a discoloring effect on them. In addition, plastic materials can easily entangle organisms such as fish leading to their suffocation and death hence reduction in available organisms for human consumption. Water polluted by oil spills also leads to the death of aquatic animals (Go Green Academy, 2013).

Several measures are necessary to tackle water pollution. Relevant authorities should enforce existing regulations concerning water pollution and come up with an even stricter penalty for those who pollute water (Hearn, 2013). Secondly, people should use less plastic and avoid littering by using designated dumping sites. Farmers, as well as householders, should minimize the use of chemicals such as fertilizers and adopt the use of environmental friendly fertility boosters like animal wastes. Since cars emit particles that lead to acidic rains, people should drive less and where possible use public transport to minimize emissions into the atmosphere (Hearn, 2013)

Water and Water Cycle

As you already know water is everywhere and all around.  However, we have a fixed amount of water on earth. It just changes its states and goes through a cyclic order, known as the Water Cycle. The water cycle is a natural process that is continuous in nature. It is the pattern in which the water from oceans, seas, lakes, etc gets evaporated and turns to vapor. After which it goes through the process of condensation, and finally precipitation when it falls back to earth as rain or snow.

What is Water Pollution?

Water pollution is the contamination of water bodies (like oceans, seas, lakes, rivers, aquifers, and groundwater) usually caused due to human activities. Water pollution is any change, minor or major in the physical, chemical or biological properties of water that eventually leads to a detrimental consequence of any living organism . Drinking water, called Potable Water, is considered safe enough for human and animal consumption.

Sources of Water Pollution

  • Domestic Waste
  • Industrial effluents
  • Insecticides and pesticides
  • Detergents and Fertilizers

Some of the water pollutions are caused by direct Sources, such as factories, waste management facilities, refineries, etc, that directly releases waste and dangerous by-products into the nearest water source without treating them. Indirect sources include pollutants that infuse in the water bodies via groundwater or soil or via the atmosphere through acidic rain.

Effects of Pollution of Water

The effects of Water Pollution are:

Diseases: In humans, drinking or consuming polluted water in any way has many disastrous effects on our health. It causes typhoid, cholera, hepatitis and various other diseases.

Eradication of Ecosystem: Ecosystem is extremely dynamic and responds to even small changes in the environment. Increasing water pollution can cause an entire ecosystem to collapse if left unchecked.

Eutrophication: Chemicals accumulation and infusion in a water body, encourages the growth of algae. The algae form a layer on top of the pond or lake. Bacteria feed on this algae and this event decreases the amount of oxygen in the water body, severely affecting the aquatic life there

Effects of the food chain: Turmoil in food chain happens when the aquatic animals (fish, prawns, seahorse, etc) consume the toxins and pollutants in the water,  and then the humans consume them.

Prevention of Water Pollution

The best way to prevent large-scale water pollution is to try and reduce its harmful effects. There are numerous small changes we can make to protect ourselves from a future where water is scarce.

Conserve Water: Conserving water should be our first aim. Water wastage is a major problem globally and we are only now waking up to the issue. Simple small changes made domestically will make a huge difference.

Treatment of sewage: Treating waste products before disposing of it in water bodies helps reduce water pollution on a large scale. Agriculture or other industries can reuse this wastewater by reducing its toxic contents.

Use of environment-friendly products: By using soluble products that do not go on to become pollutants, we can reduce the amount of water pollution caused by a household.

Life is ultimately about choices and so is water pollution. We cannot live with sewage-strewn beaches, contaminated rivers , and fish that are poisonous to drink and eat. To avoid these scenarios,  we can work together to keep the environment clean so the water bodies, plants, animals, and people who depend on it remain healthy. We can take individual or teamed action to help reduce water pollution. As an example, by using environmentally friendly detergents, not pouring oil down the drains, reducing the usage of pesticides, and so on. We can take community action too to keep our rivers and seas cleaner. And we can take action as countries and continents to pass laws against water pollution. Working together, we can make water pollution less of a problem—and the world a better place.

Title: Water Pollution – A Looming Crisis Threatening Ecosystems and Human Well-being

Water pollution is a pressing environmental issue that poses a significant threat to ecosystems, biodiversity, and human health. It occurs when harmful substances contaminate water bodies, making them unfit for their intended uses. This essay delves into the causes, consequences, and potential solutions to water pollution, emphasizing the urgent need for collective action to address this global crisis.

Water pollution arises from various sources, both human-induced and natural. Human activities play a significant role in polluting water bodies. Industrial discharge, untreated sewage, agricultural runoff, oil spills, mining activities, and improper waste disposal are among the leading causes. Industrial wastewater often contains heavy metals, toxic chemicals, and organic pollutants, which can have devastating effects on aquatic ecosystems and human health. Agricultural runoff, laden with pesticides, fertilizers, and animal waste, contaminates water bodies and contributes to eutrophication, depleting oxygen levels and harming aquatic life.

The consequences of water pollution are far-reaching and encompass ecological, economic, and health impacts. Aquatic ecosystems bear the brunt of pollution, with devastating consequences for biodiversity and food chains. Pollutants disrupt aquatic habitats, decrease water quality, and lead to the decline of fish and other marine species. This ecological imbalance has ripple effects throughout the ecosystem, affecting the entire food web.

Water pollution also has severe implications for human health. Contaminated water sources pose significant risks, as they can transmit waterborne diseases, including cholera, typhoid, dysentery, and hepatitis. Communities that rely on polluted water for drinking, cooking, and bathing are particularly vulnerable. Prolonged exposure to polluted water can lead to various health issues, such as gastrointestinal problems, skin irritations, respiratory illnesses, and even long-term health effects like cancer.

Furthermore, water pollution has economic ramifications. Polluted water bodies reduce the availability of clean water for agriculture, industry, and domestic use. This leads to increased costs for water treatment, agricultural productivity losses, and economic disruptions in sectors that rely heavily on water resources, such as fisheries and tourism.

Solutions and Mitigation Strategies

Addressing water pollution requires comprehensive strategies and collaborative efforts. Governments, industries, communities, and individuals all have a role to play in mitigating pollution and safeguarding water resources.

a. Regulatory Measures

B. wastewater treatment, c. sustainable agriculture, d. waste management, e. education and awareness.

Effective regulations and enforcement mechanisms are essential to control and prevent water pollution. Governments should establish stringent standards for industrial effluents and enforce penalties for non-compliance. Laws should be enacted to ensure proper waste disposal and treatment practices. Additionally, zoning regulations can help prevent pollution by restricting industrial activities near sensitive water bodies.

Investing in advanced wastewater treatment infrastructure is crucial. Industries should implement appropriate treatment technologies to remove pollutants from their effluents before discharge. Municipalities must prioritize the treatment of domestic sewage to prevent contamination of water bodies. Developing countries, in particular, need support and resources to build and upgrade their wastewater treatment facilities.

Adopting sustainable agricultural practices can significantly reduce pollution from agricultural activities. Encouraging the use of organic farming methods, integrated pest management, and precision irrigation can minimize the reliance on harmful pesticides and fertilizers. Proper manure management and implementing buffer zones along water bodies can also mitigate nutrient runoff and protect water quality.

Improper waste disposal is a major contributor to water pollution. Implementing comprehensive waste management systems that include recycling, proper landfill management, and promotion of waste reduction strategies is crucial. Communities should have access to adequate waste collection services, and educational campaigns can raise awareness about the importance of responsible waste disposal.

Public education and awareness programs play a vital role in addressing water pollution. Promoting water conservation practices, encouraging responsible behavior, and highlighting the link between water pollution and human health can empower individuals to take action. Educational campaigns should target schools, communities, and industries to foster a culture of environmental stewardship.

Water pollution is a critical global issue that poses severe threats to ecosystems, biodiversity, and human well-being. It demands collective action and sustainable practices to safeguard water resources. Through stringent regulations, advanced wastewater treatment, sustainable agriculture, proper waste management, and education, we can mitigate water pollution and preserve this vital resource for future generations. By recognizing the urgency of this crisis and working collaboratively, we can ensure a healthier, cleaner, and more sustainable water future.

Essay About Water Pollution Water is basic to life requirements and more than 70% of the earth’s surface is cover by water. W.H.Auden said that “thousands have lived without love, not one without water”. Water is one of our most valuable and important resources because all living organisms require water to survive their life. The human body consists of more than 50% of water, so it proves that humans can survive without food but cannot survive if without water. Fish and other living organisms need water which forms lakes, rivers and oceans as their shelter. Water pollution caused by when humans started discarding sewage and toxic chemical into the ocean, effluents from industries, manufacturing and agro-based industries, dumping, oil pollution, acid rain and so on. Sewage that causes water pollution is one of the most important problem in the earth today. Rivers contaminated by sewerage contain high levels of organic pollutants, and they become breeding grounds for harmful bacteria and viruses that may cause fish and other aquatic organisms impossible to survive and become extinct. Sewage also causes many diseases such as cholera and typhoid that will detrimental to humans. For a few more times, water has been infected with sewage and human cannot enjoy clean water. Recently, the Amazon rainforest had some of the highest deforestations in the world, which has hugely affected the access to and quality of water. This causes the area of the earth to lose a lot of freshwater due to this problem. This is heartbreaking and terrifying to think that the Amazon is the largest rainforest on the planet which creates 20% of the earth’s oxygen, basically is the “lungs of the world”. People are literally destroying the miracle of home and waste a lot of water to put out the fire. Through deforestation, trees are being removed, naturally, there is a loss of support on the soil and leads to more loss of soil. Thereby causing higher rates of soil erosion that seeps into the nearby lakes, affecting the water quality of the lake. It also makes it impossible for sea creatures to survive because of the lack of clean water and the collapsed soil that fills the river’s space, the creatures cannot multiply. In Malaysia, the environmental problem that becoming more serious from time to time is water pollution. This pollution occurs when pollutants are not treated properly to remove harmful compounds are discharged into water bodies. So it is very important to prevent polluting of water bodies and remove existing contaminants or reducing the concentration of these contaminants and use it as desired. Dealing with water pollution is something that everyone including the government and local people need to get involved with. The ways of treating polluted water are industrial wastewater treatment which the raw sewage is needed to be treated carefully and correctly in a water treatment plant before it can be released into the environment. Therefore, all manufacturing industries should assure they have a well-designed treatment facility that can prevent water pollution. Besides, we should never throw rubbish away anyhow. If the rubbish bin is none around, we can take the rubbish home and put it in the rubbish bin. These include places like beaches, riverside and water bodies. We must use water wisely and do not keep the water pipe running when not in use. It can significantly prevent water shortages and reduce the amount of dirty water that needs treatment plants. Anti-pollution laws and regulations must be applied to everyone because it always played an important role to ensure water pollution are kept to the minimum. Anti-pollution laws can as well establish measures that put restrictions for water pollution. These laws are usually directed to industries, hospitals, schools and market areas on how to dispose of, treat and manage sewage.

groundwater pollution

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

Gitanjali Rao explains the fight for clean drinking water

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 .)

free essay on water pollution

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.

free essay on water pollution

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 ).

What causes algae blooms?

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.

Video thumbnail image shows a large amount of plastic trash collected from the ocean.

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.

free essay on water pollution

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.

Can reed beds clean contaminated groundwater?

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.

free essay on water pollution

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.

The impact of plastic waste on marine life

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.

Understand global warming as a factor in the decline of dissolved oxygen in the ocean

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 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.

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.

About Water Pollution

Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.

Some of the primary sources of water pollution are Radioactive Substances, Oil Pollution, domestic sewage, solid waste, toxic waste, sediment, thermal pollution, petroleum (oil) pollution, and Agricultural Pollution.

Water is uniquely vulnerable to pollution. Known as a “universal solvent,” water is able to dissolve more substances than any other liquid on earth. It’s the reason we have Kool-Aid and brilliant blue waterfalls. It’s also why water is so easily polluted. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution it can result in the degradation of aquatic ecosystems, spread of gastrointestinal diseases and parasitic infections, eutrophication, and ocean acidification.

The contaminated water is the main cause of various diseases such as cholera and typhus. The nuclear crisis created by the tsunami of 2011, unleashed 11 million liters of radioactive water into the Pacific Ocean. Around 70% of industrial waste is dumped to water. 80% of the water pollution is caused due to domestic sewage. More than 6 billion pounds of garbage, mainly plastic end up in the oceans every year. 15 million children under the age of five years die every year from diseases caused by drinking contaminated water.
