Water Pollution and How it Harms the Environment
Global pollution is a problem. Pollution can spread to remote areas where no one lives, despite the fact that urban areas are typically more polluted than the countryside. Air pollution, water pollution, and land pollution are the three main categories of pollution. Some contaminated water has a terrible smell, a muddy appearance, and floating trash. Some contaminated water appears clean, but it contains dangerous substances that you can't see or smell.
Together, developed and developing nations must fight to conserve the environment for present and future generations. Today, we dig deep into the subject of Water Pollution. This article can be an introduction to water pollution for kids as we will read many things such as the causes of water pollution further in the article.
What is Water Pollution?
Water contamination occurs when pollutants pollute water sources and make the water unfit for use in drinking, cooking, cleaning, swimming, and other activities. Chemicals, garbage, bacteria, and parasites are examples of pollutants. Water is eventually damaged by all types of pollution. Lakes and oceans become contaminated by air pollution. Land contamination may contaminate an underground stream, a river, and ultimately the ocean. As a result, trash thrown on an empty lot can eventually contaminate a water source.

The water cycle, called the hydrological cycle, involves the following steps:
Evaporation- Because of the sun's heat, the water bodies such as oceans, lakes, seas etc., get heated up, and water evaporates in the air, forming water vapours.
Transpiration- Like evaporation, the plants and trees also lose water from them which goes to the atmosphere. This process is called transpiration.
Condensation- As the water evaporates, it starts to become cool because of the cold atmosphere in the air and because of this cooling down of water leads to the formation of clouds.
Precipitation- Because of the high movements of the wings, the clouds start to collide and then fall back to the earth’s surface in the form of rain. Sometimes they also fall back in the form of snow, hail, sleet etc., depending upon the temperature.
Runoff or Infiltration- After precipitation, the water either flows to the water bodies called runoff or is absorbed into the soil, called infiltration.
Causes of Water Pollution
There are many reasons for water pollution. Some of the reasons are directly affected by water pollution and some indirectly. Many factories and industries are dumping contaminated water, chemicals, and heavy metals into major waterways as a result of direct water pollution.
One more reason for water pollution is the use of modern techniques in farms. Farmers apply nutrients such as phosphorus, nitrogen, and potassium in the form of chemical fertilizers, manure, and sludge. It causes farms to discharge large quantities of agrochemicals, organic matter, and saline drainage into water bodies. It indirectly affects water pollution.
Pollutants can be of various types such as organic, inorganic, radioactive etc. Water pollutants are discharged either from one point from pipes, channels etc., which are called point sources or from various other sources. They can be agricultural areas, industries etc., called dispersed sources.
Some of the major forms of water pollutants are as follows:
Sewage- Domestic sewage from homes contains various forms of pathogens that threaten the human body. Sewage treatment reduces the risk of pathogens, but this risk is not eliminated.
Domestic sewage majorly contains nitrates and phosphates, and excess of these substances allows the algae to grow on the surface of water bodies. Due to this, the clean water bodies become nutrient-rich water body and then slowly, the oxygen level of water bodies reduces. This is called eutrophication or cultural eutrophication (if this step rapidly takes place by the activities of humans). This leads to the early death of water bodies.
Toxins- The industrial or factory wastes that are not disposed of properly and contain chemicals such as mercury and lead are disposed of in the water bodies making the bodies toxic, radioactive, explosive and cancerous.
Sediments- Sediments are the result of soil erosion that is formed in the water bodies. These sediments imbalances the water bodies ecologically. They also interfere in the reproductive cycle of various aquatic animals living in the water.
Thermal pollution- Water bodies get polluted because of heat, and excess heat reduces the oxygen level of the water bodies. Some of the species of fish cannot live in such water bodies with very low oxygen levels. The disposal of cold waters from the power plants leads to increased thermal pollution in the water bodies.
Petroleum oil pollution- The runoff of oil into the water bodies, either accidentally as happened in 2010 in the Gulf of Mexico, or intentionally, leads to an increase in water pollution.
As water is an important element of human health, polluted water directly affects the human body. Water pollution causes various diseases like typhoid, cholera, hepatitis, cancer, etc. Water pollution damages the plants and aquatic animals present in the river by reducing the oxygen content from the water. Polluted water washes the essential nutrients which plants need out of the soil and also leaves large amounts of aluminium in the soil, which can be harmful to plants.
Wastewater and sewage are a by-product of daily life and thus produced by each household through various activities like using soap, toilets, and detergents. Such sewage contains chemicals and bacteria which are harmful to human life and environmental health. Water pollution also leads to an imbalance in our ecosystem. Lastly, it also affects the food chain as the toxins in the water bodies are consumed by aquatic animals like fish, crabs etc., and then humans consume those animals forming turmoil.
Sometimes our tradition also becomes a cause for water pollution. Some people throw the statues of deities, flowers, pots, and ashes in rivers.
There are various standards to define water quality standards. Water meant for swimming may not be clean enough for drinking, or water meant for bathing may not be good for cooking. Therefore, there are different water standards for defined:
Stream standards- Standards that define streams, lakes, oceans or seas based on their maximum use.
Effluent standards- Define the specific standards for the level of contaminants or effluents allowed during the final discharge of those into the water bodies.
Drinking water standards- Define the level of contamination allowed in water that will be supplied for drinking or cooking in the domestic areas.
Different countries regulate their water quality standards through different acts and amendments.
While many of the solutions for water pollution need to be applied on a broader macro-level for that individual, companies, and communities can have a significant and responsible impact on the water quality. Companies, factories have to dispose of leftover chemicals and containers properly as per the product instructions. Farmers also have to reduce the use of nitrates and phosphates from fertilizers, pesticides, and contamination of groundwater.
The Swachh Bharat Mission of the government had led to reduced groundwater contamination. Under the Namami Ganga program, the government has initiated several major projects to clean Ganga. Along with all these steps, conservation of water is the very basic and important step towards water conservation and should be followed globally, treatment of sewage before their disposal in the water bodies and using environment-friendly products that do not form toxins when dissolved in water. These are some small steps that have to be taken into consideration by every human being.
As we all know, “Water is life’s matter and matrix, mother and medium. There is no life without water.” We have to save water. We must keep the water clean. If everyone will follow their responsibility against water to protect it from getting polluted then it will be easy to get clean and healthy drinking water. Clean water is a must for us and our kids' present, future, and healthy environment.
We cannot just live with contaminated waters filled with toxins and no oxygen. We cannot see our wildlife being destroyed and therefore, immediate steps have to be taken by groups of people to first clean the already contaminated water bodies and then keep a check on all the surrounding water bodies. Small steps by every individual can make a huge difference in controlling water pollution.
Water Pollution Prevention
Conserve Water
Our first priority should be to conserve water. Water wasting could be a big problem for the entire world, but we are just now becoming aware of it.
Sewage Treatment
Cleaning up waste materials before disposing of them in waterways reduces pollution on a large scale. By lowering its dangerous elements, this wastewater will be used in other sectors or in agriculture.
Usage of Eco-Friendly Materials
We will reduce the amount of pollution produced by choosing soluble products that do not alter to become pollutants.
Water contamination is the discharge of pollutants into the water body, where they dissolve, are suspended, are deposited on the bottom, and collect to the point where they hinder the aquatic ecosystem's ability to function. Water contamination is brought on by toxic compounds that easily dissolve and combine with it and come from factories, municipalities, and farms.
Healthy ecosystems depend on a complex network of organisms, including animals, plants, bacteria, and fungi, all of which interact with one another either directly or indirectly. In this article, we read about water pollution, its causes and prevention. With this, we have come to the end of our article, in case of any other doubts, feel free to ask in the comments.

FAQs on Water Pollution Essay
1. What are the effects of water pollution?
Water pollution has a great impact on human health. Water pollution kills. It's been recorded that in 2015 nearly 1.8 million people died because of water pollution. People with low income are exposed to contaminated water coming out from the industries. Presence of disease causing pathogens in drinking water are the major cause of illness which includes cholera, giardia, and typhoid. Water pollution not only affects human health but also our environment by causing algal bloom in a lake or marine environment. Water pollution also causes eutrophication which suffocates plants and animals and thus causes dead zones. Chemicals and heavy metals from industrial and municipal wastewater contaminate waterways and harm aquatic life.
2. What are the causes of Water pollution?
Water being a universal solvent is vulnerable to pollution as it dissolves more substances than any other liquid on earth. Therefore, water is easily polluted. Toxic substances from farms, towns, and factories readily dissolve into water and mix with it, resulting in water pollution. Agricultural pollution is one of the major causes of contamination in rivers and streams. The use of excessive fertilizers, pesticides, and animal waste from farms and livestock operations lets the rain wash the nutrients and pathogens—such as bacteria and viruses—into our waterways. The other major cause of water pollution is used water, termed as wastewater which comes from our sinks, showers, toilets and from commercial, industrial, and agricultural activities. It's been reported that the world's 80% wastewater flows back into the environment without being treated or reused. Oil spills and radioactive waste also cause water pollution to a great extent.
3. How to prevent water pollution?
It is important to keep our water bodies clean so we can take the following preventive measures to prevent from water pollution:
Chemicals like bleach, paint, paint thinner, ammonia, and many chemicals are becoming a serious problem. Dumping toxic chemicals down the drain or flushing them down the toilet can cause water pollution. Thus, proper disposal is important. Also, household chemicals need to be recycled.
Avoid buying products that contain persistent and dangerous chemicals. Buying non-toxic cleaners and biodegradable cleaners and pesticides cut down on water pollution.
Prevent from pouring fats or greasy substances down the drain as it might clog the drain resulting in the dumping of waste into yards or basement which can contaminate the local water bodies.
4. What is the role of medical institutions in polluting the water?
Pharmaceutical pollution affects aquatic life and thus there is a need to take preventive measures. Consumers are responsible for winding up pharmaceutical and personal care products in lakes, rivers, and streams. There's a lot of unused and expired medication that can potentially get into the water if not disposed of properly.
5. What are the major kinds of pollution?
The three main types of pollution are air pollution, water pollution or soil pollution. Some artificial pollution is also there, such as noise pollution. Factors leading to such pollution include:
Air Pollution: Industrial emissions, fires, traffic and transportation, burning of chemical waste, etc.
Water Pollution: No proper sewage disposal, pesticides in farms leaking into water bodies, industrial waste dumped into water bodies, etc.
Soil Pollution: Oil spills, acid rains, irresponsible disposal of trash, chemical waste, etc.
Noise Pollution: Honking of horns, construction activities, loud parties, etc.

Title: Water Pollution – A Looming Crisis Threatening Ecosystems and Human Well-being
Water pollution is a pressing environmental issue that poses a significant threat to ecosystems, biodiversity, and human health. It occurs when harmful substances contaminate water bodies, making them unfit for their intended uses. This essay delves into the causes, consequences, and potential solutions to water pollution, emphasizing the urgent need for collective action to address this global crisis.
Water pollution arises from various sources, both human-induced and natural. Human activities play a significant role in polluting water bodies. Industrial discharge, untreated sewage, agricultural runoff, oil spills, mining activities, and improper waste disposal are among the leading causes. Industrial wastewater often contains heavy metals, toxic chemicals, and organic pollutants, which can have devastating effects on aquatic ecosystems and human health. Agricultural runoff, laden with pesticides, fertilizers, and animal waste, contaminates water bodies and contributes to eutrophication, depleting oxygen levels and harming aquatic life.
The consequences of water pollution are far-reaching and encompass ecological, economic, and health impacts. Aquatic ecosystems bear the brunt of pollution, with devastating consequences for biodiversity and food chains. Pollutants disrupt aquatic habitats, decrease water quality, and lead to the decline of fish and other marine species. This ecological imbalance has ripple effects throughout the ecosystem, affecting the entire food web.
Water pollution also has severe implications for human health. Contaminated water sources pose significant risks, as they can transmit waterborne diseases, including cholera, typhoid, dysentery, and hepatitis. Communities that rely on polluted water for drinking, cooking, and bathing are particularly vulnerable. Prolonged exposure to polluted water can lead to various health issues, such as gastrointestinal problems, skin irritations, respiratory illnesses, and even long-term health effects like cancer.
Furthermore, water pollution has economic ramifications. Polluted water bodies reduce the availability of clean water for agriculture, industry, and domestic use. This leads to increased costs for water treatment, agricultural productivity losses, and economic disruptions in sectors that rely heavily on water resources, such as fisheries and tourism.
Solutions and Mitigation Strategies
Addressing water pollution requires comprehensive strategies and collaborative efforts. Governments, industries, communities, and individuals all have a role to play in mitigating pollution and safeguarding water resources.
a. Regulatory Measures
B. wastewater treatment, c. sustainable agriculture, d. waste management, e. education and awareness.
Effective regulations and enforcement mechanisms are essential to control and prevent water pollution. Governments should establish stringent standards for industrial effluents and enforce penalties for non-compliance. Laws should be enacted to ensure proper waste disposal and treatment practices. Additionally, zoning regulations can help prevent pollution by restricting industrial activities near sensitive water bodies.
Investing in advanced wastewater treatment infrastructure is crucial. Industries should implement appropriate treatment technologies to remove pollutants from their effluents before discharge. Municipalities must prioritize the treatment of domestic sewage to prevent contamination of water bodies. Developing countries, in particular, need support and resources to build and upgrade their wastewater treatment facilities.
Adopting sustainable agricultural practices can significantly reduce pollution from agricultural activities. Encouraging the use of organic farming methods, integrated pest management, and precision irrigation can minimize the reliance on harmful pesticides and fertilizers. Proper manure management and implementing buffer zones along water bodies can also mitigate nutrient runoff and protect water quality.
Improper waste disposal is a major contributor to water pollution. Implementing comprehensive waste management systems that include recycling, proper landfill management, and promotion of waste reduction strategies is crucial. Communities should have access to adequate waste collection services, and educational campaigns can raise awareness about the importance of responsible waste disposal.
Public education and awareness programs play a vital role in addressing water pollution. Promoting water conservation practices, encouraging responsible behavior, and highlighting the link between water pollution and human health can empower individuals to take action. Educational campaigns should target schools, communities, and industries to foster a culture of environmental stewardship.
Water pollution is a critical global issue that poses severe threats to ecosystems, biodiversity, and human well-being. It demands collective action and sustainable practices to safeguard water resources. Through stringent regulations, advanced wastewater treatment, sustainable agriculture, proper waste management, and education, we can mitigate water pollution and preserve this vital resource for future generations. By recognizing the urgency of this crisis and working collaboratively, we can ensure a healthier, cleaner, and more sustainable water future.

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.
Recent News
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 pollution on essay water pollution on essay](https://cdn.britannica.com/29/202829-050-D4EC1777/industrial-waste-water-pipe-pollution.jpg?w=300)
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 ).
![water pollution on essay What causes algae blooms?](https://cdn.britannica.com/15/253815-138-6C1BA71C/algae-blooms-red-tides-botany.jpg?w=800&h=450&c=crop)
Domestic sewage is also a major source of plant nutrients , mainly nitrates and phosphates . Excess nitrates and phosphates in water promote the growth of algae , sometimes causing unusually dense and rapid growths known as algal blooms . When the algae die, oxygen dissolved in the water declines because microorganisms use oxygen to digest algae during the process of decomposition ( see also biochemical oxygen demand ). Anaerobic organisms (organisms that do not require oxygen to live) then metabolize the organic wastes, releasing gases such as methane and hydrogen sulfide , which are harmful to the aerobic (oxygen-requiring) forms of life. The process by which a lake changes from a clean, clear condition—with a relatively low concentration of dissolved nutrients and a balanced aquatic community —to a nutrient-rich, algae-filled state and thence to an oxygen-deficient, waste-filled condition is called eutrophication . Eutrophication is a naturally occurring, slow, and inevitable process. However, when it is accelerated by human activity and water pollution (a phenomenon called cultural eutrophication ), it can lead to the premature aging and death of a body of water.

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

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

Waste is considered toxic if it is poisonous , radioactive , explosive , carcinogenic (causing cancer ), mutagenic (causing damage to chromosomes ), teratogenic (causing birth defects), or bioaccumulative (that is, increasing in concentration at the higher ends of food chains). Sources of toxic chemicals include improperly disposed wastewater from industrial plants and chemical process facilities ( lead , mercury , chromium ) as well as surface runoff containing pesticides used on agricultural areas and suburban lawns ( chlordane , dieldrin , heptachlor). (For a more-detailed treatment of toxic chemicals, see poison and toxic waste .)
Sediment (e.g., silt ) resulting from soil erosion or construction activity can be carried into water bodies by surface runoff . Suspended sediment interferes with the penetration of sunlight and upsets the ecological balance of a body of water. Also, it can disrupt the reproductive cycles of fish and other forms of life , and when it settles out of suspension it can smother bottom-dwelling organisms.
Heat is considered to be a water pollutant because it decreases the capacity of water to hold dissolved oxygen in solution, and it increases the rate of metabolism of fish. Valuable species of game fish (e.g., trout ) cannot survive in water with very low levels of dissolved oxygen . A major source of heat is the practice of discharging cooling water from power plants into rivers; the discharged water may be as much as 15 °C (27 °F) warmer than the naturally occurring water. The rise in water temperatures because of global warming can also be considered a form of thermal pollution.

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

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

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

Another ocean pollution problem is the seasonal formation of “ dead zones” (i.e., hypoxic areas, where dissolved oxygen levels drop so low that most higher forms of aquatic life vanish) in certain coastal areas. The cause is nutrient enrichment from dispersed agricultural runoff and concomitant algal blooms. Dead zones occur worldwide; one of the largest of these (sometimes as large as 22,730 square km [8,776 square miles]) forms annually in the Gulf of Mexico , beginning at the Mississippi River delta.
Although pure water is rarely found in nature (because of the strong tendency of water to dissolve other substances), the characterization of water quality (i.e., clean or polluted) is a function of the intended use of the water. For example, water that is clean enough for swimming and fishing may not be clean enough for drinking and cooking. Water quality standards (limits on the amount of impurities allowed in water intended for a particular use) provide a legal framework for the prevention of water pollution of all types.
There are several types of water quality standards. Stream standards are those that classify streams, rivers , and lakes on the basis of their maximum beneficial use; they set allowable levels of specific substances or qualities (e.g., dissolved oxygen , turbidity, pH) allowed in those bodies of water, based on their given classification. Effluent (water outflow) standards set specific limits on the levels of contaminants (e.g., biochemical oxygen demand , suspended solids, nitrogen ) allowed in the final discharges from wastewater-treatment plants. Drinking-water standards include limits on the levels of specific contaminants allowed in potable water delivered to homes for domestic use. In the United States , the Clean Water Act and its amendments regulate water quality and set minimum standards for waste discharges for each industry as well as regulations for specific problems such as toxic chemicals and oil spills . In the European Union , water quality is governed by the Water Framework Directive, the Drinking Water Directive, and other laws . ( See also wastewater treatment .)

Water 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?
When many pollutants such as garbage, chemicals, bacteria, household waste, industrial waste, etc get mixed in the water resources and make the water unfit for cooking, drinking, cleaning, etc. it is known as water pollution. Water pollution damages the quality of water. lakes, water streams, rivers, etc may become polluted and eventually they will pollute the oceans. All this will directly or indirectly affect the lives of us humans and the animals deteriorating our health.
Essay on Water Pollution in 200 Words
Water is plentiful on Earth, present both above and beneath its surface. A variety of water bodies, such as rivers, ponds, seas, and oceans, can be found on the planet’s surface. Despite Earth’s ability to naturally replenish its water, we are gradually depleting and mishandling this abundant resource.
Although water covers 71% of the Earth’s surface and land constitutes the remaining 29%, the rapid expansion of water pollution is impacting both marine life and humans.
Contaminants
Water pollution stems significantly from city sewage and industrial waste discharge. Indirect sources of water pollution include contaminants that reach water supplies via soil, groundwater systems, and precipitation.
Chemical pollutants pose a greater challenge in terms of removal compared to visible impurities, which can be filtered out through physical cleaning. The addition of chemicals alters water’s properties, rendering it unsafe and potentially lethal for consumption.
Solution
Prioritizing water infrastructure enhancement is vital for sustainable water management, with a focus on water efficiency and conservation.
Furthermore, rainwater harvesting and reuse serve as effective strategies to curb water pollution. Reclaimed wastewater and collected rainwater alleviate stress on groundwater and other natural water sources.
Groundwater recharge, which transfers water from surface sources to groundwater, is a well-known approach to mitigate water scarcity. These measures collectively contribute to safeguarding the planet’s water resources for present and future generations.

Essay on Water Pollution in 500 Words
The term “water pollution” is employed when human or natural factors lead to contamination of bodies of water, such as rivers, lakes, and oceans. Responsible management is now imperative to address this significant environmental concern. The primary sources of water contamination are human-related activities like urbanization, industrialization, deforestation, improper waste disposal, and the establishment of landfills.
Reasons for Water Pollution
The availability of freshwater on our planet is limited, and pollution only increases this scarcity. Every year, a substantial amount of fresh water is lost due to industrial and various other types of pollution. Pollutants encompass visible waste items of varying sizes as well as intangible, hazardous, and lethal compounds.
Numerous factories are situated in proximity to water bodies, utilizing freshwater to transport their waste. This industrial waste carries inherent toxicity, jeopardizing the well-being of both plant and animal life. Individuals living close to polluted water sources frequently suffer from skin problems, respiratory ailments, and occasionally even life-threatening health conditions.
Water contamination is also intensified by urban waste and sewage, adding to the problem. Each household generates considerable waste annually, including plastic, chemicals, wood, and other materials. Inadequate waste disposal methods result in this refusal to infiltrate aquatic ecosystems like rivers, lakes, and streams, leading to pollution.
Methods of Water Pollution Management
Raising awareness about the causes and consequences of water pollution is crucial in significantly reducing its prevalence. Encouraging community or organizational clean-up initiatives on a weekly or monthly basis plays a pivotal role.
To eradicate water contamination completely, stringent legislation needs to be formulated and diligently enforced. Rigorous oversight would promote accountability, potentially deterring individuals and groups from polluting. Each individual should recognize the impact of their daily actions and take steps to contribute to a better world for generations to come.
Real-Life Encounter
My affection for my town has always been heightened by its abundant lakes, rivers, and forests. During one of my walks alongside the river that flowed through my village, I was struck by the unusual hues swirling within the water. The once-familiar crystal-clear blue had been replaced by a murky brown shade, accompanied by a potent, unpleasant odour. Intrigued, I decided to investigate further, descending to the riverbank for a closer look at the source of the peculiar colours and smells. Upon closer inspection, I observed peculiar foam bubbles floating on the water’s surface.
Suddenly, a commotion behind me caught my attention, and I turned to witness a group of people hastening toward the river. Their frantic shouts and vigorous gestures conveyed their panic, prompting me to realize that a grave situation was unfolding. As the group reached the river, they were confronted with the distressing sight of numerous lifeless fish floating on the water’s surface.
Following a comprehensive investigation, it was revealed that a local factory had been releasing toxic chemicals into the river, resulting in extensive pollution and the devastation of the ecosystem. This investigation left me stunned and disheartened, acknowledging the significant effort required to restore the river to its own form.

Water Pollution in the US: Causes and Control Essay

- As a template for you assignment
Introduction: Water Pollution in the United States
Discussion: causes of water pollution and the means of reducing it, conclusion: spring cleaning on a global scale, reference list.
The issue of water scarcity and to following strategy for its sustainable use is quite tricky. While technically being a renewable resource, water should not be viewed as the one that can replenish itself, either – due to the dangerously high rates of water pollution, the existing amounts of freshwater are getting increasingly low.
Although water pollution can hardly be ceased entirely, the current rates of water pollution can be reduced by resorting to the sustainable principle of water use in both the industrial area and the realm of the household. By increasing awareness among the population and developing a sustainable approach towards the usage of the existing water resources, one will be capable of addressing the water pollution rates in the USA.
Key Causes: The Dirty Side of Water Use
Unfortunately, there is no single negative factor that contributes to the increase in water pollution rates, and there is no malefactor, either – instead, it is the inconsiderate use of the existing resources that triggers water pollution. Among the key factors that trigger water pollution, its industrial usage seems to be the reason for concern for the most part. However, it is the urban runoff (i.e., the abuse of water resources by the residents of the urban areas) that triggers the so-called nonpoint (i.e., irreversible) source pollution.
Along with nutrients and chemicals pollution, the contamination by sewage discharges is an especially huge threat to the American resources of clean water.
Industrial waste
While having to comply with the existing regulations regarding environmental protection, a range of companies resort to unclean practices by dumping their waste into the areas, where the waste becomes a threat to water. The recent Exxon scandal has shown that the estimated $8.9 billion of environmental damages has been made in 2015 (THE EDITORIAL BOARD, 2015).
Underground storage leakages
Underground storage tanks, which traditionally contain petroleum and other harmful substances, often tend to leak, therefore, triggering the release of petrol and the related substances into water, hence the water pollution.
Septic tanks
Contributing to underground storage leaking (), septic tanks contribute to water pollution in the U.S. significantly by discharging around 2 sq. m of waste into the water daily (BELIN, 2015).
Ocean dumping
Another essential factor that defines the rates of water pollution in the USA, ocean dumping needs to be reduced significantly.
Oil pollution
The notorious case of Exxon’s oil spill in 2015 (THE EDITORIAL BOARD, 2015) has shown that oil pollution must be prevented at all costs. The 2013 oil pollution issues have caused the USA 125 miles of coast, affecting the water and the wildlife in the vicinity (Oil spills and disasters, 2014).
Radioactive waste
Much like ocean dumping, radioactive waste disposal is difficult to trace and, therefore, it is easier for organizations dealing with the substances in question to dispose of them improperly.
Fossil fuels burning
Emitting around 117,000, 164,000 and 208,000 billion Btu annually (Comparison against other fossil fuels, 2015), natural gas, oil and coal correspondingly pose a serious threat to the quality of water in the United States.
Landfill leakage
The problem of land pollution and the following contamination of groundwater is a major problem for the United States. According to the 2015 statistics, 56% of trash in the USA is transported to landfills (BRADFORD, 2010). The leakage from the latter, in its turn, poisons the groundwater in the vicinity with detritus from rotten food and the pollutants from plastic items decomposition (BRADFORD, 2010).
Animal waste
Animal droppings also decompose into the elements that, when introduced to the soil, penetrate the groundwater area and, therefore, pollute the water.
Atmospheric deposition
The destruction of atmosphere layers leads to the exposition of water resources to an extreme level of radiation and, therefore, triggers their untimely desiccation.
Global warming
One of the most notorious and, nevertheless, the one of the lengthiest effect, global warming causes the U.S. rivers to overflow; as a result, the sewage contents will pour into clean water, contaminating it. 1.2 trillion gallons of sewage contaminate freshwater annually in the U.S (Water pollution facts, n. d., para. 24).
Death of aquatic animals
Global warming triggers a steady rise in the temperature of the water, thus, causing deaths of numerous aquatic organisms. The decomposition elements of the latter pollute the waters of the Atlantic Ocean coast and the American rivers.
By introducing wastewater to rivers and oceans, the authorities of the U.S. risk the contamination of the aquatic animals and, therefore, the transfer of pollution by the sick animals to the clean water areas.
Food chains disruption
The effects of wastewater and food chains disruption are, in fact, reciprocal, as the latter trigger an increase in the death toll among the water life forms and, therefore, cause the contamination of water with the decomposition products, the algae, which are no longer consumed by the deceased aquatic animals, etc.
Ecosystems destruction
As a result of the lack of proper food, the inhabitants of the American rivers and seas, as well as the Atlantic, the Pacific and the Arctic Oceans are likely to die out. The lack of certain elements of the ocean food chain, in its turn, will result in higher death tolls among the aquatic animals and, thus, higher decomposition rates.
Reaching the point of no return
Agriculture.
To facilitate proper growth of crops, American farmers and farming organizations spend water resources unreasonably. 130 billion gallons being used for irrigation and livestock (ADMIN, 2011), agriculture is the leading cause of water scarcity in some of the regions of the USA.
Municipal point sources
Leading to a significant reduction of dissolved oxygen, MPS also drastically affect the cleanness of water in the U.S.
Urban runoff
Made of impervious materials, pavement does not allow snow and rain to trickle into the ground; as a result, the hydrological water cycle is disrupted.
Stream/habitat changes
Another factor that causes numerous water creatures to die or migrate, stream and habitat changes alter essential characteristics of the environment, thus, causing water to become filled with bacteria, algae, etc.
Means of Control: Starting with Personal Responsibility
Reasonable use of water.
Sustainability as the basis towards the use of water resources can be viewed as the strategy that should make the basis for the proper use of water. The specified approach must be deployed at every level of water resources distribution from municipal to agricultural.
Pollution Prevention Act
Adopted in 1990, the Act creates the premises for “reducing the amount of pollution through cost-effective changes in production, operation, and raw materials use” (Summary of the Pollution Prevention Act, 1990, par. 1).
Raising awareness among the citizen
Apart from designing legal ramifications, state authorities should consider the idea of influencing people on a personal level. By promoting the responsible use of resources, one will be capable of reducing water waste rates significantly.
Reducing the number of solids
Solid waste reduction is likely to postpone the process of water supplies exhaustion.
EPA laws enhancement
Although the approaches suggested by EPA are generally reasonable, they seem to have been disregarded when defining the strategies for water resources use in the USA. Thus, there is a need to facilitate compliance with EPA laws. This can be done by imposing fines on the individuals and organizations abusing water resources.
Ocean Dumping Program
The program was designed in 2014 after the Marine Protection, Research, and Sanctuaries Act (Research project description, 2014) and requires sustainable and responsible disposal of waste.
Oil Pollution Prevention regulation
Designed for addressing the issues such as the case of Exxon and, therefore, preventing the catastrophes related to oil spills, the specified act requires that specific standards for oil tanks design and the storage of oil therein should be complied with.
Solutions to be designed: radioactive waste and direct injection
Even though there is no solution to handling the issue of radioactive waste management, as well as the process of direct injection, measures must be taken to facilitate remoteness of the specified types of waste from any life forms and sources of water.
Abandoning the use of landfills
Although there is no alternative to landfill use for waste management at present, a more appropriate location of landfills can be considered a possibility. Specifically, the regions, where groundwater flows are generally very low, can be viewed as an option (BRADFORD 2010).
Animal waste collection
While the process of collecting animal waste may be rather complicated due to the difficulties related to tracing the locations of stray animals, making people take proper care of their pets and picking up the droppings left by the latter can be carried out comparatively easily by issuing the corresponding laws.
Global warming prevention
A very complex and difficult task, it involves a variety of measures starting from the sustainable use of resources to the transfer to driving hybrid vehicles and refrain from usage of a variety of pollutants including aerosols.
Marine sustainability
Introducing a set of more rigid regulations regarding the waste disposal for businesses along with the development of marine sustainability principles may help in not only preventing water pollution but also addressing the negative effects that it has caused.
The U.S. authorities have adopted a range of programs aimed at water sanitation, including the USAID’s Water and Development Strategy (USAID, 2013).
![](http://pechenka.online/777/templates/cheerup1/res/banner1.gif)
Sustainable use of resources
The introduction of individuals and organizations to a reasonable usage of water has recently been viewed as an opportunity in the United States.
Sustaining ecosystems: green infrastructure
Likewise, the key principles of sustainability should be adopted when allowing the key ecosystems to retain their
Addressing nonpoint source pollution
Clean water act.
Another suggestion for reconsidering the current rates of water usage, the CWA presupposes that the “basic structure for regulating discharges of pollutants into the waters of the United States” (Summary of the Clean Water Act, 2015) should be established and that similar regulations should be provided for the use of freshwater in the USA.
NPDES Permit Program
A program aimed at regulating the current use of water, it regulates the sources, which discharge pollutants into the ocean (NPDES Stormwater Permit Program, 2015).
Wastewater programs
The phenomenon of wastewater harvesting () has been created for the sake of reducing urban runoff and may have a significant effect on sustainable water use once the awareness regarding the subject matter is increased. Even a more adequate use of water by the residents of the area can be facilitated with the introduction of similar programs. The refusal to use impervious pavement materials for sidewalks and driveways should also be viewed as an option (Urban nonpoint source fact sheet, 2003).
Total maximum daily loads
Seeing that no alternative to waste disposal for major companies have been designed yet, the organizations that dump waste into the ocean have to comply with the existing restrictions on the amount of waste that they can deposit. Unfortunately, not all states follow the requirements set by the TMDL Act (see Appendix A).
Watershed management
Likewise, the watershed management approach, which presupposes that careful studies of the watershed should be carried out with the following location of the problem areas and the measurers designed for addressing the emerging issues in a manner as timely and efficient as possible. There is no secret that watershed management presupposes dealing with not only the issue of water pollution but also the problem of habitat destruction. In other words, watershed management programs adopted in the USA currently allow for handling several issues simultaneously and, therefore, promoting a more sustainable approach towards the consumption and usage of the existing water resource.
Green infrastructure
The aforementioned sustainability issue can be attained through a series of actions that are determined for enhancing habitat recovery. Indeed, as it has been stressed above, the lack of sustainability in the management of the water resources in the USA triggers an immediate decay of the existing variability in American nature. As a result, a range of species faces the threat of extinction, therefore, triggering the overpopulation of water with smaller animals and algae (i.e., the elements that used to be the food of the extinct species). Thus, by restoring the habitats that have been destroyed, the American community will be capable of replenishing water resources or, at the very least, saving the ones that they still have at their disposal.
National Water Quality Initiative
Though having started their activity comparatively recently, the proponents of the NWQI movement have already designated “approximately five percent of EQIP financial assistance to targeted agricultural conservation practice implementation in 165 HUC 12 NWQI watersheds” (Session M5: quantifying agricultural nonpoint sources and controls, 2013, p. 2).
Fostering personal responsibility
Last, but not least, the idea of promoting personal responsibility as the basis for sustainable water use must be viewed as an option.
Although water is traditionally viewed as a renewable resource, the nonpoint pollution factors in the United States make the threat of water scarcity dangerously high. Therefore, a more sustainable approach towards the use of water not only industrial but also household levels must be introduced into the framework of the U.S. water usage.

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.

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 on Water Pollution : Causes, Effects & Solutions
February 2, 2021 by Study Mentor Leave a Comment
Water is one of the most important factors essential for sustaining life. Every organism, no matter how big or small, requires water to live.
You must’ve noticed that water quality has undergone a sea change over the years. The water has gotten harder and harder.
The color of water in rivers and lakes has significantly changed. The crystal clear surface on water bodies was a thing of the past and we no longer get to see a picturesque image of a clean and perfect water body anymore.
The tap water we receive can no longer be used for drinking, and we are forced to buy separate drinking water, install water purifying devices in our homes.
Have you wondered why we are forced to go in for such applications at our homes. There is no answer for water scarcity in big cities today and people are forced to live with the bitter truth.
Table of Contents
What is water pollution?
Water pollution is nothing but contamination of water bodies with chemicals, toxins and effluents let out from industrial establishments and factories.
These toxins contain harmful concentrations of lead, Sulphur, heavy metals and detergents in them.
Not just that, water bodies are mixed with sewage water and one can imagine the extent of dirt and filth that is contained in the waters of river bodies, thus making them highly polluted.
Pollution is tainting or forcefully mixing harmful and toxic substances into environment. These substances that endanger the consistency and integrity of the environment are called Pollutants.
Pollutants have been ever rampant since man entered the industrial ages.
The environment has been enduring the abuse we afflicted on it since ages. Industries, factories, etc. contribute to pollution on a large scale.
The daily activities that we perform, also pollute the earth due to inefficiency of the methods we use. Alarming quantities of pollutants are being produced and released.
Causes of water pollution
Speaking about water, most of the industries and factories have leftover chemical effluents. They release these residual products into primary water sources like rivers streams, lakes, fresh water tanks etc.
These residues may be a mixture of a myriad of chemically toxic substances.
The microbes present in the natural sources of water have the ability to purify the water to some extent. But the problem arises when we dump more Pollutants before the current batch of water is purified.
Purified, in this context, means oxidizing the water.
Microbes present in water have the natural ability to oxidize it. But constant human intended interference has almost nullified that ability.
In short, pollutants just overtake the good microbial activity and instead cause damage to water sources by inducing them with filth and dirt.
The activities of the microbes in cleaning up the water reduce to a low minimum or may not take place at all. Waste water from domestic sources is also often dumped into rivers. This pollutes the entire source.

Effects of water pollution
Water pollution affects us on a daily basis. The cases of water borne disease are on the rise. Since water is one of the building blocks of life, we have but no choice to consume the same water in adequacy.
The dangers of polluted water increases when people unknowingly use polluted water for daily purposes.
This mostly occurs in rural areas, where rivers are a prime source of water.
Factories set up near river bodies may be releasing effluents and people downstream maybe using the same water for drinking purposes and for other daily activities.
It is common knowledge that 70 percent of the earth is covered by water. But not all of this water can be used for drinking and household purposes.
Only a small percentage is fresh water, and most of the other share in the percentage finds itself frozen at the Poles.
The advent of pollution has further reduced the potable water resources. Water available today is way more polluted than it was ages ago.
Our quality of life is greatly affected by this. Use of polluted water causes diseases and ailments. It can be directly linked to the receding length of our lifespan.
Solutions for water pollution
Humans have realized that they have greatly affected the environment in a bad way. Everywhere, efforts are being made to conserve water.
Water treatment plants are setup everywhere. Every waste disposal station has a water treatment department, so that all the chemical and other harmful substances can be removed from water before it is let into the main source.
This has been pivotal in controlling pollution of water. Rules and regulations have been made stringent for factories and industries, regarding their effluent emission, both through the air and through water.
Domestic waste disposal techniques have been improved and proper steps taken in the right direction.
It is entirely up to us, what we decide to do, with our water sources. Global warming is becoming an ever gaping issue and a worldwide concern. There’s always fear of the rains being more infrequent and unseasonal.
What on earth do we do without adequate water. The hardships we’d have to face to obtain enough water for sustaining looks so terrible if we were to quest for a suitable answer.
The everyday tasks that we do would become incredibly difficult. We need to take measures ourselves, to save water and keep it from being polluted.
We must start conserving water in our homes. Only then will the next generation have even the slightest hope for a well-rounded future.
Water pollution is actually a two-fold issue raising global concerns today.
The first issue, the most common one as we know is of the contamination of water by toxins and measures to reduce the contamination and improve the quality of water.
The second one is more serious and pertains to the availability of potable water on earth after some years, putting a question mark on the survival of life on earth itself.
We talk about beautifying our lakes, restoring the cleanliness of our water bodies, removing their contaminants and making them toxic free.
Yes, this is definitely required at the moment and there have been measures taken in the right direction to make our rivers clean and clear.
Specific installations of dust collector and dirt remover equipment’s in river basins have been employed to collect waste material from river surfaces.
This is primarily to remove hard traces of waste or what we can call as visible wastes. This also takes removes unnecessary growth of phytoplankton in rivers, thus letting the river waters breathe at ease.
Regarding toxin removal from river waters, purification using reverse osmosis methods, chemical filtration methods and other treatments using distillation methods are employed to make them free from chemical residues.
Much other advancement have been achieved and successfully employed in the river basins of our country to restore the natural beauty of lakes and rivers.
The best example of river water cleaning in our country is the cleanliness drive carried out at river Ganga in the holy city of Varanasi.
The government of India took it up as a big challenge to clean the river waters at the region and was successful in achieving its mission.
It is only with citizen co-operation and participation that any reformative measures taken by the governments will prove fruitful and worthy of action.
We blame successive governments for not cleaning up our river beds, for not providing us clean drinking water, for not beautifying our lakes etc.
In the melee, we forget our own responsibilities of acting with care and concern.
If we visit rural areas and spot women washing their clothes, utensils and cattle in river waters, it is our duty to educate them and spread awareness about their wrong acts.
We ought to tell them that they aren’t supposed to pollute the river water.

500 Words Essay on Water Pollution
Water pollution is an escalating global concern that threatens the health of our planet and its inhabitants. It refers to the contamination of water bodies such as rivers, oceans, lakes, and groundwater, caused by human activities. This pollution affects not only the quality of water but also the broader ecosystem, impacting both aquatic and terrestrial life forms.
Water pollution can be attributed to a myriad of sources, broadly categorized into point sources and non-point sources. Point sources relate to pollutants directly discharged into water bodies from identifiable locations such as factories, sewage treatment plants, and oil spills. Non-point sources, on the other hand, are diffuse and harder to control, including agricultural runoff, urban runoff, and atmospheric deposition.
Industrial activities are a significant contributor to water pollution. The unchecked dumping of toxic waste materials into water bodies leads to a drastic degradation in water quality. Similarly, agricultural practices contribute significantly to water pollution through the use of synthetic fertilizers and pesticides. These chemicals leach into groundwater or are washed into rivers and lakes, leading to nutrient pollution.
The Consequences of Water Pollution
Water pollution also poses a significant threat to public health. Contaminated water is a breeding ground for waterborne diseases such as cholera, dysentery, and typhoid. With over 780 million people lacking access to clean water, the health impact is substantial and disproportionately affects vulnerable populations.
Addressing Water Pollution
Public awareness and education are also key in addressing this issue. By understanding the causes and effects of water pollution, individuals can make informed decisions and contribute to the solution, whether through responsible consumption, waste disposal, or advocacy.
Water pollution is a pressing issue that requires immediate and sustained attention. While the situation is dire, it is not insurmountable. Through collective action, stringent regulations, technological advancements, and increased awareness, we can mitigate water pollution and safeguard our water resources for future generations. The fight against water pollution is not just an environmental obligation, but also a prerequisite for our survival and well-being.

Essay on Water Pollution: Types, Causes, Effects & Prevention
March 10, 2021 by Sandeep
Water Pollution Essay: When water gets contaminated by pollutants making it unhealthy and unfit to consume, we call it water pollution. The pollution of water bodies like oceans, rivers, lakes, and underground sources has drastically affected life forms. Domestic and industrial wastes, pesticides and effluents mainly pollute water.
Essay on Water Pollution 500 Words in English
Below we have provided Water Pollution Essay in English, suitable for class 3, 4, 5, 6, 7, 8, 9 & 10. This essay is drafted in simple and easy words.
Water is undoubtedly one of the essential resources on our planet. It is vital for the survival of all living organisms. Water takes over two-thirds of the Earth’s surface. It is a priceless commodity that has been contaminated and depleted to a critical level with time. The addition of harmful foreign substances into water bodies is known as water pollution. These water bodies can be in the form of aquifers, rivers, lakes, ponds, seas, groundwater, streams, waterfalls, and oceans. Human activities are the prime reason for the adulteration of water bodies.
Types of Water Pollution
Water pollution can be of three kinds – groundwater pollution’s, surface water pollution, and marine pollution.
The contamination of groundwater is known as groundwater pollution. Industrial effluents, dirty water from drains and sewage, which flow on the land surface, seep down the soil and mix with the groundwater. Surface water pollution includes contamination of open water bodies (like rivers, lakes, and oceans) present on Earth’s surface. Lack of proper sanitation and uncontrollable discharge are the major contributors.
Marine pollution involves large water bodies. Wastewater discharges in the river make their way to the seas and oceans, thus causing pollution. Aquatic species become exposed to hazardous chemicals. Food chains get disrupted. Oxygen content in the water bodies is reduced. Marine life is adversely affected as a result. These polluted water bodies become the hub for microbes and spread epidemics like cholera, typhoid, hepatitis, and diarrhoea.
Causes of Water Pollution
Water tends to dissolve almost everything. It is known as the universal solvent. This feature enables it to dissolve toxic substances. These toxicities arise from factories, refineries, waste disposal sites, acid rains, detergents, domestic waste, etc. Some of the major causes of water pollution are:
- Sewage: Every day, tons of waste matter generated from farmlands, commercial sites and households are dumped into the lakes and rivers. These wastes which remain untreated contain harmful chemicals that can be poisonous to plants, animals, and humans.
- Industrial Effluents: Industrial waste largely contributes to the adulteration of water bodies. Direct disposal of these wastes has disastrous effects on the ecosystem. Chemical effluents from tanning industries contain poisonous compounds, volatile matter, and heavy metals. This water then mixes with the river and contaminates the underground water table.
- Eutrophication: It is the process that occurs when large amounts of nutrients in the water bodies result in the formation and growth of algae on the surface of the water. Bacteria feed on these algae. Hence, aquatic organisms like fishes and plants get depleted of oxygen. Their habitat is destroyed, and the quality of water is critically reduced.
- Oil Spills: Leakages from ships and tankers result in oil spills. This is one of the most dangerous modes of water pollution. When the oil gets spilt, it forms a layer over the water surface. This layer prevents the penetration of oxygen, which is essential for the survival of marine plants and animals.
- Affected River Banks: Lack of sanitation measures in the villages has resulted in defecation in open areas (especially near river banks). Washing clothes and cattle in the lakes is a common practice. Solid waste accumulation is not a rare sight. Litters composed of plastics, glasses, Styrofoam, etc., do not decompose well and stay in the water for years.
- Indirect Sources: These are the pollutants that indirectly lead to water pollution. They can be chemical dumps, septic tanks, pesticides, hazardous wastes, radioactive substances, etc. Radioactive wastes generated from atomic power plants and other medical procedures are dangerous.
Prevention of Water Pollution
Besides predominantly affecting our health, water pollution can have disastrous effects on our ecosystem. Toxicant pass through the affected aquatic species to us humans. The food chain is badly influenced by it. Prevention of water pollution is essential. Conservation of water must be the first step. Preventive measures include sewage water treatment, using environment-friendly products, reduction in plastic consumption, proper disposal of chemical liquids, solid waste management, and less use of pesticides.
Apart from that, drains must be cleaned more often. The implementation of proper sanitary measures by the government in the villages is a great step. Mass awareness through media and entertainment can help sensitize people about the issue. Educating people, especially in rural areas, can ensure a positive outcome. Enforcement of appropriate laws for Industries and other production sectors can prove beneficial. Natural reserves of water must be safeguarded, and a balance must be maintained in our diversified environment.
