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.

Water pollution: an introduction

by Chris Woodford . Last updated: October 1, 2023.

O ver two thirds of Earth's surface is covered by water ; less than a third is taken up by land. As Earth's population continues to grow, people are putting ever-increasing pressure on the planet's water resources. In a sense, our oceans, rivers , and other inland waters are being "squeezed" by human activities—not so they take up less room, but so their quality is reduced. Poorer water quality means water pollution .

We know that pollution is a human problem because it is a relatively recent development in the planet's history: before the 19th century Industrial Revolution, people lived more in harmony with their immediate environment. As industrialization has spread around the globe, so the problem of pollution has spread with it. When Earth's population was much smaller, no one believed pollution would ever present a serious problem. It was once popularly believed that the oceans were far too big to pollute. Today, with around 7 billion people on the planet, it has become apparent that there are limits. Pollution is one of the signs that humans have exceeded those limits.

What is water pollution?

Water pollution can be defined in many ways. Usually, it means one or more substances have built up in water to such an extent that they cause problems for animals or people. Oceans, lakes, rivers, and other inland waters can naturally clean up a certain amount of pollution by dispersing it harmlessly. If you poured a cup of black ink into a river, the ink would quickly disappear into the river's much larger volume of clean water. The ink would still be there in the river, but in such a low concentration that you would not be able to see it. At such low levels, the chemicals in the ink probably would not present any real problem. However, if you poured gallons of ink into a river every few seconds through a pipe, the river would quickly turn black. The chemicals in the ink could very quickly have an effect on the quality of the water. This, in turn, could affect the health of all the plants, animals, and humans whose lives depend on the river.

Photo: Pollution means adding substances to the environment that don't belong there—like the air pollution from this smokestack. Pollution is not always as obvious as this, however.

Thus, water pollution is all about quantities : how much of a polluting substance is released and how big a volume of water it is released into. A small quantity of a toxic chemical may have little impact if it is spilled into the ocean from a ship. But the same amount of the same chemical can have a much bigger impact pumped into a lake or river, where there is less clean water to disperse it.

"The introduction by man, directly or indirectly, of substances or energy into the marine environment (including estuaries) resulting in such deleterious effects as harm to living resources, hazards to human health, hindrance to marine activities, including fishing, impairment of quality for use of sea water and reduction of amenities." [1]

What are the main types of water pollution?

When we think of Earth's water resources, we think of huge oceans, lakes, and rivers. Water resources like these are called surface waters . The most obvious type of water pollution affects surface waters. For example, a spill from an oil tanker creates an oil slick that can affect a vast area of the ocean.

Not all of Earth's water sits on its surface, however. A great deal of water is held in underground rock structures known as aquifers, which we cannot see and seldom think about. Water stored underground in aquifers is known as groundwater . Aquifers feed our rivers and supply much of our drinking water. They too can become polluted, for example, when weed killers used in people's gardens drain into the ground. Groundwater pollution is much less obvious than surface-water pollution, but is no less of a problem. In 1996, a study in Iowa in the United States found that over half the state's groundwater wells were contaminated with weed killers. You might think things would have improved since then, but, two decades on, all that's really changed is the name of the chemicals we're using. Today, numerous scientific studies are still finding weed killers in groundwater in worrying quantities: a 2012 study discovered glyphosate in 41 percent of 140 groundwater samples from Catalonia, Spain; scientific opinion differs on whether this is safe or not. [2]

Surface waters and groundwater are the two types of water resources that pollution affects. There are also two different ways in which pollution can occur. If pollution comes from a single location, such as a discharge pipe attached to a factory, it is known as point-source pollution . Other examples of point source pollution include an oil spill from a tanker, a discharge from a smoke stack (factory chimney), or someone pouring oil from their car down a drain. A great deal of water pollution happens not from one single source but from many different scattered sources. This is called nonpoint-source pollution .

When point-source pollution enters the environment, the place most affected is usually the area immediately around the source. For example, when a tanker accident occurs, the oil slick is concentrated around the tanker itself and, in the right ocean conditions, the pollution disperses the further away from the tanker you go. This is less likely to happen with nonpoint source pollution which, by definition, enters the environment from many different places at once.

Sometimes pollution that enters the environment in one place has an effect hundreds or even thousands of miles away. This is known as transboundary pollution . One example is the way radioactive waste travels through the oceans from nuclear reprocessing plants in England and France to nearby countries such as Ireland and Norway.

How do we know when water is polluted?

Some forms of water pollution are very obvious: everyone has seen TV news footage of oil slicks filmed from helicopters flying overhead. Water pollution is usually less obvious and much harder to detect than this. But how can we measure water pollution when we cannot see it? How do we even know it's there?

There are two main ways of measuring the quality of water. One is to take samples of the water and measure the concentrations of different chemicals that it contains. If the chemicals are dangerous or the concentrations are too great, we can regard the water as polluted. Measurements like this are known as chemical indicators of water quality. Another way to measure water quality involves examining the fish, insects, and other invertebrates that the water will support. If many different types of creatures can live in a river, the quality is likely to be very good; if the river supports no fish life at all, the quality is obviously much poorer. Measurements like this are called biological indicators of water quality.

What are the causes of water pollution?

Most water pollution doesn't begin in the water itself. Take the oceans: around 80 percent of ocean pollution enters our seas from the land. [16] Virtually any human activity can have an effect on the quality of our water environment. When farmers fertilize the fields, the chemicals they use are gradually washed by rain into the groundwater or surface waters nearby. Sometimes the causes of water pollution are quite surprising. Chemicals released by smokestacks (chimneys) can enter the atmosphere and then fall back to earth as rain, entering seas, rivers, and lakes and causing water pollution. That's called atmospheric deposition . Water pollution has many different causes and this is one of the reasons why it is such a difficult problem to solve.

With billions of people on the planet, disposing of sewage waste is a major problem. According to 2017 figures from the World Health Organization, some 2 billion people (about a quarter of the world's population) don't have access to safe drinking water or the most basic sanitation, 3.4 billion (60 people of the population) lack "safely managed" sanitation (unshared, with waste properly treated). Although there have been great improvements in securing access to clean water, relatively little, genuine progress has been made on improving global sanitation in the last decade. [20] Sewage disposal affects people's immediate environments and leads to water-related illnesses such as diarrhea that kills 525,000 children under five each year. [3] (Back in 2002, the World Health Organization estimated that water-related diseases could kill as many as 135 million people by 2020; in 2019, the WHO was still estimating the annual death toll from poor water and sanitation at over 800,000 people a year.) In developed countries, most people have flush toilets that take sewage waste quickly and hygienically away from their homes.

Yet the problem of sewage disposal does not end there. When you flush the toilet, the waste has to go somewhere and, even after it leaves the sewage treatment works, there is still waste to dispose of. Sometimes sewage waste is pumped untreated into the sea. Until the early 1990s, around 5 million tons of sewage was dumped by barge from New York City each year. [4] According to 2002 figures from the UK government's Department for the Environment, Food, and Rural Affairs (DEFRA), the sewers of Britain collect around 11 billion liters of waste water every day; there are still 31,000 sewage overflow pipes through which, in certain circumstances, such as heavy storms, raw sewage is pumped untreated into the sea. [5] The New River that crosses the border from Mexico into California once carried with it 20–25 million gallons (76–95 million liters) of raw sewage each day; a new waste water plant on the US-Mexico border, completed in 2007, substantially solved that problem. [6] Unfortunately, even in some of the richest nations, the practice of dumping sewage into the sea continues. In early 2012, it was reported that the tiny island of Guernsey (between Britain and France) has decided to continue dumping 16,000 tons of raw sewage into the sea each day.

In theory, sewage is a completely natural substance that should be broken down harmlessly in the environment: 90 percent of sewage is water. [7] In practice, sewage contains all kinds of other chemicals, from the pharmaceutical drugs people take to the paper , plastic , and other wastes they flush down their toilets. When people are sick with viruses, the sewage they produce carries those viruses into the environment. It is possible to catch illnesses such as hepatitis, typhoid, and cholera from river and sea water.

Suitably treated and used in moderate quantities, sewage can be a fertilizer: it returns important nutrients to the environment, such as nitrogen and phosphorus, which plants and animals need for growth. The trouble is, sewage is often released in much greater quantities than the natural environment can cope with. Chemical fertilizers used by farmers also add nutrients to the soil, which drain into rivers and seas and add to the fertilizing effect of the sewage. Together, sewage and fertilizers can cause a massive increase in the growth of algae or plankton that overwhelms huge areas of oceans, lakes, or rivers. This is known as a harmful algal bloom (also known as an HAB or red tide, because it can turn the water red). It is harmful because it removes oxygen from the water that kills other forms of life, leading to what is known as a dead zone . The Gulf of Mexico has one of the world's most spectacular dead zones. Each summer, according to studies by the NOAA , it typically grows to an area of around 5500–6500 square miles (14,000–16,800 square kilometers), which is about the same size as the state of Connecticut. [21]

Waste water

A few statistics illustrate the scale of the problem that waste water (chemicals washed down drains and discharged from factories) can cause. Around half of all ocean pollution is caused by sewage and waste water. Each year, the world generates perhaps 5–10 billion tons of industrial waste, much of which is pumped untreated into rivers, oceans, and other waterways. [8] In the United States alone, around 400,000 factories take clean water from rivers, and many pump polluted waters back in their place. However, there have been major improvements in waste water treatment recently. Since 1970, in the United States, the Environmental Protection Agency (EPA) has invested about $70 billion in improving water treatment plants that, as of 2021, serve around 90 percent of the US population (compared to just 69 percent in 1972). However, another $271 billion is still needed to update and upgrade the system. [15]

Factories are point sources of water pollution, but quite a lot of water is polluted by ordinary people from nonpoint sources; this is how ordinary water becomes waste water in the first place. Virtually everyone pours chemicals of one sort or another down their drains or toilets. Even detergents used in washing machines and dishwashers eventually end up in our rivers and oceans. So do the pesticides we use on our gardens. A lot of toxic pollution also enters waste water from highway runoff . Highways are typically covered with a cocktail of toxic chemicals—everything from spilled fuel and brake fluids to bits of worn tires (themselves made from chemical additives) and exhaust emissions. When it rains, these chemicals wash into drains and rivers. It is not unusual for heavy summer rainstorms to wash toxic chemicals into rivers in such concentrations that they kill large numbers of fish overnight. It has been estimated that, in one year, the highway runoff from a single large city leaks as much oil into our water environment as a typical tanker spill. Some highway runoff runs away into drains; others can pollute groundwater or accumulate in the land next to a road, making it increasingly toxic as the years go by.

Chemical waste

Detergents are relatively mild substances. At the opposite end of the spectrum are highly toxic chemicals such as polychlorinated biphenyls (PCBs) . They were once widely used to manufacture electronic circuit boards , but their harmful effects have now been recognized and their use is highly restricted in many countries. Nevertheless, an estimated half million tons of PCBs were discharged into the environment during the 20th century. [9] In a classic example of transboundary pollution, traces of PCBs have even been found in birds and fish in the Arctic. They were carried there through the oceans, thousands of miles from where they originally entered the environment. Although PCBs are widely banned, their effects will be felt for many decades because they last a long time in the environment without breaking down.

Another kind of toxic pollution comes from heavy metals , such as lead, cadmium, and mercury. Lead was once commonly used in gasoline (petrol), though its use is now restricted in some countries. Mercury and cadmium are still used in batteries (though some brands now use other metals instead). Until recently, a highly toxic chemical called tributyltin (TBT) was used in paints to protect boats from the ravaging effects of the oceans. Ironically, however, TBT was gradually recognized as a pollutant: boats painted with it were doing as much damage to the oceans as the oceans were doing to the boats.

The best known example of heavy metal pollution in the oceans took place in 1938 when a Japanese factory discharged a significant amount of mercury metal into Minamata Bay, contaminating the fish stocks there. It took a decade for the problem to come to light. By that time, many local people had eaten the fish and around 2000 were poisoned. Hundreds of people were left dead or disabled. [10]

Radioactive waste

People view radioactive waste with great alarm—and for good reason. At high enough concentrations it can kill; in lower concentrations it can cause cancers and other illnesses. The biggest sources of radioactive pollution in Europe are two factories that reprocess waste fuel from nuclear power plants : Sellafield on the north-west coast of Britain and Cap La Hague on the north coast of France. Both discharge radioactive waste water into the sea, which ocean currents then carry around the world. Countries such as Norway, which lie downstream from Britain, receive significant doses of radioactive pollution from Sellafield. [19] The Norwegian government has repeatedly complained that Sellafield has increased radiation levels along its coast by 6–10 times. Both the Irish and Norwegian governments continue to press for the plant's closure. [11]

Oil pollution

Photo: Oil-tanker spills are the most spectacular forms of pollution and the ones that catch public attention, but only a fraction of all water pollution happens this way. Photo by Lamar Gore courtesy of US Fish & Wildlife Service Photo Library and US National Archive .

When we think of ocean pollution, huge black oil slicks often spring to mind, yet these spectacular accidents represent only a tiny fraction of all the pollution entering our oceans. Even considering oil by itself, tanker spills are not as significant as they might seem: only 12 percent of the oil that enters the oceans comes from tanker accidents; over 70 percent of oil pollution at sea comes from routine shipping and from the oil people pour down drains on land. [12] However, what makes tanker spills so destructive is the sheer quantity of oil they release at once — in other words, the concentration of oil they produce in one very localized part of the marine environment. The biggest oil spill in recent years (and the biggest ever spill in US waters) occurred when the tanker Exxon Valdez broke up in Prince William Sound in Alaska in 1989. Around 12 million gallons (44 million liters) of oil were released into the pristine wilderness—enough to fill your living room 800 times over! Estimates of the marine animals killed in the spill vary from approximately 1000 sea otters and 34,000 birds to as many as 2800 sea otters and 250,000 sea birds. Several billion salmon and herring eggs are also believed to have been destroyed. [13]

If you've ever taken part in a community beach clean, you'll know that plastic is far and away the most common substance that washes up with the waves. There are three reasons for this: plastic is one of the most common materials, used for making virtually every kind of manufactured object from clothing to automobile parts; plastic is light and floats easily so it can travel enormous distances across the oceans; most plastics are not biodegradable (they do not break down naturally in the environment), which means that things like plastic bottle tops can survive in the marine environment for a long time. (A plastic bottle can survive an estimated 450 years in the ocean and plastic fishing line can last up to 600 years.)

While plastics are not toxic in quite the same way as poisonous chemicals, they nevertheless present a major hazard to seabirds, fish, and other marine creatures. For example, plastic fishing lines and other debris can strangle or choke fish. (This is sometimes called ghost fishing .) About half of all the world's seabird species are known to have eaten plastic residues. In one study of 450 shearwaters in the North Pacific, over 80 percent of the birds were found to contain plastic residues in their stomachs. In the early 1990s, marine scientist Tim Benton collected debris from a 2km (1.5 mile) length of beach in the remote Pitcairn islands in the South Pacific. His study recorded approximately a thousand pieces of garbage including 268 pieces of plastic, 71 plastic bottles, and two dolls heads. [14]

Alien species

Most people's idea of water pollution involves things like sewage, toxic metals, or oil slicks, but pollution can be biological as well as chemical. In some parts of the world, alien species are a major problem. Alien species (sometimes known as invasive species ) are animals or plants from one region that have been introduced into a different ecosystem where they do not belong. Outside their normal environment, they have no natural predators, so they rapidly run wild, crowding out the usual animals or plants that thrive there. Common examples of alien species include zebra mussels in the Great Lakes of the USA, which were carried there from Europe by ballast water (waste water flushed from ships ). The Mediterranean Sea has been invaded by a kind of alien algae called Caulerpa taxifolia . In the Black Sea, an alien jellyfish called Mnemiopsis leidyi reduced fish stocks by 90 percent after arriving in ballast water. In San Francisco Bay, Asian clams called Potamocorbula amurensis, also introduced by ballast water, have dramatically altered the ecosystem. In 1999, Cornell University's David Pimentel estimated that alien invaders like this cost the US economy $123 billion a year; in 2014, the European Commission put the cost to Europe at €12 billion a year and "growing all the time. [18]

Other forms of pollution

These are the most common forms of pollution—but by no means the only ones. Heat or thermal pollution from factories and power plants also causes problems in rivers. By raising the temperature, it reduces the amount of oxygen dissolved in the water, thus also reducing the level of aquatic life that the river can support. Another type of pollution involves the disruption of sediments (fine-grained powders) that flow from rivers into the sea. Dams built for hydroelectric power or water reservoirs can reduce the sediment flow. This reduces the formation of beaches, increases coastal erosion (the natural destruction of cliffs by the sea), and reduces the flow of nutrients from rivers into seas (potentially reducing coastal fish stocks). Increased sediments can also present a problem. During construction work, soil, rock, and other fine powders sometimes enters nearby rivers in large quantities, causing it to become turbid (muddy or silted). The extra sediment can block the gills of fish, effectively suffocating them. Construction firms often now take precautions to prevent this kind of pollution from happening.

What are the effects of water pollution?

Some people believe pollution is an inescapable result of human activity: they argue that if we want to have factories, cities, ships, cars, oil, and coastal resorts, some degree of pollution is almost certain to result. In other words, pollution is a necessary evil that people must put up with if they want to make progress. Fortunately, not everyone agrees with this view. One reason people have woken up to the problem of pollution is that it brings costs of its own that undermine any economic benefits that come about by polluting.

Take oil spills, for example. They can happen if tankers are too poorly built to survive accidents at sea. But the economic benefit of compromising on tanker quality brings an economic cost when an oil spill occurs. The oil can wash up on nearby beaches, devastate the ecosystem, and severely affect tourism. The main problem is that the people who bear the cost of the spill (typically a small coastal community) are not the people who caused the problem in the first place (the people who operate the tanker). Yet, arguably, everyone who puts gasoline (petrol) into their car—or uses almost any kind of petroleum-fueled transport—contributes to the problem in some way. So oil spills are a problem for everyone, not just people who live by the coast and tanker operates.

Sewage is another good example of how pollution can affect us all. Sewage discharged into coastal waters can wash up on beaches and cause a health hazard. People who bathe or surf in the water can fall ill if they swallow polluted water—yet sewage can have other harmful effects too: it can poison shellfish (such as cockles and mussels) that grow near the shore. People who eat poisoned shellfish risk suffering from an acute—and sometimes fatal—illness called paralytic shellfish poisoning. Shellfish is no longer caught along many shores because it is simply too polluted with sewage or toxic chemical wastes that have discharged from the land nearby.

Pollution matters because it harms the environment on which people depend. The environment is not something distant and separate from our lives. It's not a pretty shoreline hundreds of miles from our homes or a wilderness landscape that we see only on TV. The environment is everything that surrounds us that gives us life and health. Destroying the environment ultimately reduces the quality of our own lives—and that, most selfishly, is why pollution should matter to all of us.

How can we stop water pollution?

There is no easy way to solve water pollution; if there were, it wouldn't be so much of a problem. Broadly speaking, there are three different things that can help to tackle the problem—education, laws, and economics—and they work together as a team.

Making people aware of the problem is the first step to solving it. In the early 1990s, when surfers in Britain grew tired of catching illnesses from water polluted with sewage, they formed a group called Surfers Against Sewage to force governments and water companies to clean up their act. People who've grown tired of walking the world's polluted beaches often band together to organize community beach-cleaning sessions. Anglers who no longer catch so many fish have campaigned for tougher penalties against factories that pour pollution into our rivers. Greater public awareness can make a positive difference.

One of the biggest problems with water pollution is its transboundary nature. Many rivers cross countries, while seas span whole continents. Pollution discharged by factories in one country with poor environmental standards can cause problems in neighboring nations, even when they have tougher laws and higher standards. Environmental laws can make it tougher for people to pollute, but to be really effective they have to operate across national and international borders. This is why we have international laws governing the oceans, such as the 1982 UN Convention on the Law of the Sea (signed by over 120 nations), the 1972 London (Dumping) Convention , the 1978 MARPOL International Convention for the Prevention of Pollution from Ships , and the 1998 OSPAR Convention for the Protection of the Marine Environment of the North East Atlantic . The European Union has water-protection laws (known as directives) that apply to all of its member states. They include the 1976 Bathing Water Directive (updated 2006), which seeks to ensure the quality of the waters that people use for recreation. Most countries also have their own water pollution laws. In the United States, for example, there is the 1972 Clean Water Act and the 1974 Safe Drinking Water Act .

Most environmental experts agree that the best way to tackle pollution is through something called the polluter pays principle . This means that whoever causes pollution should have to pay to clean it up, one way or another. Polluter pays can operate in all kinds of ways. It could mean that tanker owners should have to take out insurance that covers the cost of oil spill cleanups, for example. It could also mean that shoppers should have to pay for their plastic grocery bags, as is now common in Ireland, to encourage recycling and minimize waste. Or it could mean that factories that use rivers must have their water inlet pipes downstream of their effluent outflow pipes, so if they cause pollution they themselves are the first people to suffer. Ultimately, the polluter pays principle is designed to deter people from polluting by making it less expensive for them to behave in an environmentally responsible way.

Our clean future

Life is ultimately about choices—and so is pollution. We can live with sewage-strewn beaches, dead rivers, and fish that are too poisonous to eat. Or we can work together to keep the environment clean so the plants, animals, and people who depend on it remain healthy. We can take individual action to help reduce water pollution, for example, by using environmentally friendly detergents , not pouring oil down drains, reducing pesticides, and so on. We can take community action too, by helping out on beach cleans or litter picks to keep our rivers and seas that little bit cleaner. And we can take action as countries and continents to pass laws that will make pollution harder and the world less polluted. Working together, we can make pollution less of a problem—and the world a better place.

Essay on Water Pollution for Students and Children

500+ words essay on water pollution.

Water is the most important resource for survival on a planet. It is the essence of life on our planet – Earth. Yet if you ever see a river or lake around your city, it would be evident to you that we are facing a very serious problem of Water pollution. Let us educate ourselves about water and water pollution . Two-thirds of the Earth’s surface is covered by water , seventy-six perfect of your body is made up of water.

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.

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 .)

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.

“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.

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)

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.

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.

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.

Introduction

Causes of water pollution, effects of water pollution, prevention of water pollution, treatment of waste water, reference list.

Pollution refers to the introduction of foreign substances to pure contents. The foreign substances are referred to as pollutants. Water pollution therefore refers to the introduction of pollutants into a water body. The pollutants come from various sources including human wastes, domestic wastes, industrial and agricultural by-products and even floods (Woodford, 2012, p. 1).

This paper takes a step by step analysis of the causes, effects, treatment of polluted waters and finally how humans can strive towards prevention of water pollution through minimization of pollutants disposal into water bodies.

Domestic wastes are a major cause of pollution originating mainly from household facilities such as kitchens and bathrooms. This includes waste water from kitchens resulting from washing of utensils and consisting of foodstuff wastes. The waste water carries with it food left-overs which when released into the sewage systems ends up rotting and releasing toxic substances.

Even the most well designed housing units do not have well-built septic tanks for disposal of such wastes (Donald, 2011, p. 72). However, even with the well built septic tanks, clogging of the pipes does occur causing the pipes to burst releasing their content into the environment. Various other kinds of chemicals result from the use of bathrooms which are either constituents of soaps or detergents used in washing.

Human wastes mainly consist of faecal matter disposed off poorly in the environment. This is a major problem in slums and in rural areas especially in the developing world. Most of these areas do not have proper toilets. The wastes are disposed anyhow in the environment and during heavy rains the wastes are washed off into large water bodies.

Further pollution occurs when these wastes decompose releasing toxic products into water bodies especially large amounts of carbon dioxide which may suffocate aquatic animals (Thompson, 2012, p 1). In slums, there is free flow of sewage in open tunnels even when there are no rains. The sewage from various households coalesces and forms big streams which eventually find their way into water bodies.

Many farmers employ the use of fertilizers to boost their production. However, these fertilizers are inorganic chemicals in nature and not all are utilized by the plants.

The components which are not absorbed by the plants end up accumulating in the soil and during heavy rains they are washed off and flown into water bodies as agricultural run-offs (Freedman, 2009, p. 145). Since these components are inorganic in nature, they are not easily biodegradable thus end up accumulating at the base of the water bodies and become toxic to aquatic life.

Industrial by-products form a major cause of water pollution resulting from several unwanted products which are released during production. These are referred to as by products which may be inorganic chemicals, solid wastes or used water. Most industries use water as either reactant or as coolant or both.

This water is again released into water bodies from which it was initially collected (Thompson, 2012, p. 1). In most cases, industries release hot water which had been used as a coolant and may end up killing young aquatic animals.

Floods which occur as run-offs following heavy down pour of rains. When it rains in highland areas, the floods come down stream with large amounts of wastes ranging from the human, domestic and agricultural wastes. When floods occur after a drought where animals lost their lives, they carry with them the decaying remains of the dead animals. This results in the pollution of the receiving water bodies (Aral, 2010, p. 59).

Global warming can be considered as a secondary cause of pollution as it does not directly cause pollution but only contributes to the occurrence of the other pollutants. With global warming, there are increased incidences of flush floods sweeping people, farms and animals while the green house gases which contribute to global warming also contribute to the occurrence of acid rains. The acid rain pollutes water bodies especially the oceans with adverse effects on aquatic life and the users of such waters.

Spread of water borne diseases where some of the contaminants in water pollutants are disease-causing microorganisms. Most common of these are the cholera causing Vibrio cholerae and typhoid fever causing Salmonella typhus (Haughton & Hunter, 2008, p. 212).

These microorganisms spread and multiply in the water bodies and spread these diseases to many users including animals and humans especially those using river water for consumption. These waters are also carried over long distances where these infections continue to be spread.

Famine may also result from water pollution especially where water pollution causes spread of diseases to both plants and animals causing their deaths (Greis, 2012, p. 21).

In areas where water is polluted with inorganic chemicals which are toxic to plants, there is likelihood of the plants drying up thus less vegetation cover and lack of rains to support agriculture. Crops grown near the water bodies and supplied with water through irrigation are likely not going to produce good harvest and may even fail completely when supplied with polluted water.

Decline of the fishing industry may as well result which mainly depends on fish from major water bodies such as lakes which might be under the threat of pollution. If these water bodies get polluted, they will not be able to support aquatic life which includes that of fish. This would spell doom to the fishing industry (Woodford, 2012, p. 1). The major causes of fish death in their natural habitats has been found to be chemicals released from industries and hot water released by the same industries.

Deterioration of major water bodies occur as chemical wastes and organic pollutants accumulate in the water bodies and they continue decaying and the nutrient levels in lakes rise thus supporting a larger number and variety of vegetation. Algal blooms are likely to come up and cover the major water bodies.

This may mean a death penalty to lakes as growth of vegetation colonizes the waters. The blooms end up suffocating life out of the aquatic animals which eventually become extinct while the waters dry out. This is also evident in Lake Victoria in East Africa where the weed, water hyacinth has colonized large chunks of the lake and covered it completely (Thompson, 2012, p. 1).

It is threatening other forms of life in the lake and even the usual fishing activities have been hampered. The lake is under threat of extinction should the spread of the weed be neglected. However, certain species of fish seem to have benefitted from the weeds invasion of the lake as their population has been reported to be on the rise following consumption of the weed as a food source.

As water sources become depleted due to pollution, more and more people lack adequate water for domestic and commercial use. They end up spending a lot of their resources in obtaining water since water is life. In addition to lack of water for domestic use, polluted water will spread diseases thus more resources will be invested in managing those ailments.

Lastly, the industries which rely heavily on the large water bodies for water will have to spend more on tapping water due to pollution of the existing sources (Freedman, 2009, p. 149). This inflated cost will ultimately be transferred to the consumers. All these effects of water pollution will result in people spending more thus raising the cost of living. This has been experienced in Kenya especially in the Lake Victoria region.

Since water is life, it is important that it is safeguarded from potential sources of pollutants. This basically will involve getting ways of preventing the pollutants from getting into the water bodies (Imbriaco, 2011, p. 1). All potential pollutants should be treated before they are released into the environment. The strategies which can help ensure this include, but not limited to;

Governments should take the lead in protecting water resources. It is therefore important that governments come up with legislations that will ensure the protection of the environment.

Such legislations would include laws on sanitation in residential areas that ensure people have proper toilets and proper disposal facilities. Implementation of laws on waste treatment by industries before being released into the environment, guidelines on use of fertilizers for agricultural purposes and laws on general environmental conservation should also be put in place (Imbriaco, 2011, p. 1).

Another way of preventing water pollution is the introduction of organic farming where organic manure is used in place of the common inorganic fertilizers. Farmers should be encouraged to embrace this kind of farming which ensures that the manure used is biodegradable and do not end up accumulating in the water bodies once they are washed off by floods (Donald, 2011, p. 84).

Since agricultural wastes are used as source of manure, the raw wastes released into the environment will be few and sometimes none. In addition to cutting operation costs for the farmer, it also helps conserve the environment.

Proper waste management should also be practised where wastes produced from both domestic use and industrial used are disposed appropriately. For domestic waste, household users should dig up compost pits to dispose off their wastes. The organic wastes are allowed to decompose while the inorganic ones are burnt inside the pits (Aral, 2010, p. 52).

On the same note, industries should set up treatment plants for their wastes where the potentially harmful wastes are treated before being released into the environment. Areas without proper sanitation like the slums and rural areas should improve and come up with latrines for proper human waste management.

There are plants which can be built to clean up the already polluted waters. These are composed of wells for decomposition of the organic wastes after which the water is filtered to rid it of the particulate matter then finally treated with chlorine before being released back into the water system (Haughton & Hunter 2008, p. 216). This should be made a requirement for all industries releasing waste water.

Water is a very important part of life and therefore it must be protected as a resource. It is clear that human beings are virtually solely responsible for all almost all sources of pollution (Greis, 2012, p. 21). It is therefore important that each individual takes up responsibility to protect water as a natural resource. The government also needs to ensure legislations are in place and that they are complied with at all times.

Essay On Water Pollution [Short + Long]

Water pollution is a severe environmental problem around the world. We must be very conscious of this problem and make others informed about it. We exist because of the existence of water.

Water is one of the fundamental needs to survive on this planet. All the organisms on Earth require water in one form or another. Water pollution has become an enemy to most organisms. Polluted water brings us diseases and physical imbalances.

Short Essay On Water Pollution | 250 words

Introduction.

Water pollution is a severe environmental problem around the world. Water pollution happens when pollutants like agricultural wastes and toxic industrial wastes and other chemicals mix in water bodies like lakes, underground water, rivers, and oceans. It is affecting the lives of humans, animals, aquatic animals and also plants.

The Causes!

There are several causes of water pollution the draining of sewage waste into the water, waste materials disposed into the rivers and lakes, agricultural wastes like chemical fertilizers and pesticides and the burning of fossil fuels that is also a cause of acid rain. Water is easily polluted because of its high solubility in a range of materials.

The Effects!

Water pollution is not only affecting the lives of human beings but also animals, plants and aquatic animals and aquatic plants are affected. It is also a reason for the imbalance of the ecosystem. Water pollution is solely a reason for various water-generated diseases. Several deaths occur every year caused by water pollution.

The Solutions!

The use of water efficiently is a responsibility for all human beings and also saving water helps us preserve the water for later use. We should not dispose of the waste material in our dustbins into the water bodies.

Also, industries must release their chemical wastes after the proper treatment so that water does not get polluted. Most importantly, Awareness must be spread among people who are not aware enough and young ones.

Concluding, Water is a requirement for all of us. It is a gift of mother nature and we need to use it efficiently to live a good life. As a natural resource, it is limited and we all should understand its actual value. Individuals and the government should perform their duties to curb this problem.

Long Essay On Water Pollution | 500 Words

Water is a basic need to execute life on Earth. But daily, we are presently making it unclean by doing various types of activities. Contaminated water is a cause of many types of diseases such as Typhoid, Jaundice, cholera etc, A large portion of deaths globally are caused by water pollution.

We must be very conscious of this problem and make others informed about it. This is a powerful way to counter this puzzle. The government should implement laws to prevent the industries’ harmful substances and disposal of chemicals into the water. We must use water very carefully and efficiently.

Its Importance

The earth is abundant in water but only a small fraction (about 0.3 %) of that volume is usable by humans. We need to recognise the real price of water because we are not using this valuable gift of nature efficiently. All living bodies, be they a human, animals, or plants, are dependent on water to live a life.

Everyone is wholly dependent on pure and potable water. We are just using it in a process like it is free. Yes, it is free because its worth can’t be measured in any currency. We can’t even last a long life without water because it maintains body functions to work well and helps with digestion.

Effects of water pollution

Water pollution is the single reason for several diseases like jaundice, diarrhoea, cholera, and typhoid. Globally, a large part of deaths occurs because of the consumption of contaminated water. It Impacts the natural ecosystem too.

It is a reason for the scarcity of clean water in the environment. We already know that clean water is a basic need for human beings and water pollution is reducing the amount of clean water.

Plus, pollution in water bodies is a threat to aquatic animals and plants. It can reduce their lifespan and even can make them go extinct.

Causes of water pollution

Water is very vulnerable to being exposed to pollution. Water is known as a “universal solvent,” It is capable to dissolve more substances than any other fluid on Earth. It’s the reason water is so easily polluted. Draining sewage waste into rivers pollutes water at a greater level.

The other reason is pollution from industries that fill untreated water in rivers and lakes. The third reason is chemical fertilizers and pesticides are also dirtying the water. Moreover,

Additionally, Burning fossil fuel is an indirect way to pollute water. burning of fossil fuel produces a large amount of ash in which particles that contain toxic chemicals exist when mixed with water vapour resulting in acid rain.

How to reduce water pollution

• Awareness: It is the most effective way to reduce the amount of water pollution.
• Preventing the disposal of waste into the water: The government should take some steps in this regard to control the disposal of waste materials into the water.
• Making rules for the industries: Industries that contribute to polluting water are needed to have screws tightened on them and penalised if found violating the guidelines.
• Saving water : It is not the direct method to reduce water pollution but it will help a lot regarding this problem.
• Proper dumping of sewage waste: Sewage waste is a great source of water pollution There is a need to make proper arrangements for its dumping.
• Water conservation: Water conservation means saving water. It is a global responsibility for all human beings. And it is a great way to prevent water pollution.
• Using eco-friendly products: By using insoluble products that do not mix with water easily helps reduce water pollution.

Final words

To sum it up, Water is a part of our climate and our lives. It is a very basic need for people to live a life on this planet but living a life is not sufficient. We need pure water to live a healthy life and we are well aware of the existing situation. So, finally, we need to preserve it from being polluted if we want to demand a healthy lifestyle for our forthcoming generations.
