Water Pollution and How it Harms the Environment

Global pollution is a problem. Pollution can spread to remote areas where no one lives, despite the fact that urban areas are typically more polluted than the countryside. Air pollution, water pollution, and land pollution are the three main categories of pollution. Some contaminated water has a terrible smell, a muddy appearance, and floating trash. Some contaminated water appears clean, but it contains dangerous substances that you can't see or smell.

Together, developed and developing nations must fight to conserve the environment for present and future generations. Today, we dig deep into the subject of Water Pollution. This article can be an introduction to water pollution for kids as we will read many things such as the causes of water pollution further in the article.

What is Water Pollution?

Water contamination occurs when pollutants pollute water sources and make the water unfit for use in drinking, cooking, cleaning, swimming, and other activities. Chemicals, garbage, bacteria, and parasites are examples of pollutants. Water is eventually damaged by all types of pollution. Lakes and oceans become contaminated by air pollution. Land contamination may contaminate an underground stream, a river, and ultimately the ocean. As a result, trash thrown on an empty lot can eventually contaminate a water source.

Water Pollution

The water cycle, called  the hydrological cycle, involves the following steps:

Evaporation- Because of the sun's heat, the water bodies such as oceans, lakes, seas etc., get heated up, and water evaporates in the air, forming water vapours.

Transpiration- Like evaporation, the plants and trees also lose water from them which goes to the atmosphere. This process is called transpiration.

Condensation- As the water evaporates, it starts to become cool because of the cold atmosphere in the air and because of this cooling down of water leads to the formation of clouds.

Precipitation- Because of the high movements of the wings, the clouds start to collide and then fall back to the earth’s surface in the form of rain. Sometimes they also fall back in the form of snow, hail, sleet etc., depending upon the temperature.

Runoff or Infiltration- After precipitation, the water either flows to the water bodies called runoff or is absorbed into the soil, called infiltration.

Causes of Water Pollution

There are many reasons for water pollution. Some of the reasons are directly affected by water pollution and some indirectly. Many factories and industries are dumping contaminated water, chemicals, and heavy metals into major waterways as a result of direct water pollution. 

One more reason for water pollution is the use of modern techniques in farms. Farmers apply nutrients such as phosphorus, nitrogen, and potassium in the form of chemical fertilizers, manure, and sludge. It causes farms to discharge large quantities of agrochemicals, organic matter, and saline drainage into water bodies. It indirectly affects water pollution.

Pollutants can be of various types such as organic, inorganic, radioactive etc. Water pollutants are discharged either from one point from pipes, channels etc., which are called point sources or from various other sources. They can be agricultural areas, industries etc., called dispersed sources. 

Some of the major forms of water pollutants are as follows:

Sewage- Domestic sewage from homes contains various forms of pathogens that threaten the human body. Sewage treatment reduces the risk of pathogens, but this risk is not eliminated. 

Domestic sewage majorly contains nitrates and phosphates, and excess of these substances allows the algae to grow on the surface of water bodies. Due to this, the clean water bodies become nutrient-rich water body and then slowly, the oxygen level of water bodies reduces. This is called eutrophication or cultural eutrophication (if this step rapidly takes place by the activities of humans). This leads to the early death of water bodies.

Toxins- The industrial or factory wastes that are not disposed of properly and contain chemicals such as mercury and lead are disposed of in the water bodies making the bodies toxic, radioactive, explosive and cancerous.

Sediments- Sediments are the result of soil erosion that is formed in the water bodies. These sediments imbalances the water bodies ecologically. They also interfere in the reproductive cycle of various aquatic animals living in the water.

Thermal pollution- Water bodies get polluted because of heat, and excess heat reduces the oxygen level of the water bodies. Some of the species of fish cannot live in such water bodies with very low oxygen levels. The disposal of cold waters from the power plants leads to increased thermal pollution in the water bodies.

Petroleum oil pollution- The runoff of oil into the water bodies, either accidentally as happened in 2010 in the Gulf of Mexico, or intentionally, leads to an increase in water pollution.

As water is an important element of human health, polluted water directly affects the human body. Water pollution causes various diseases like typhoid, cholera, hepatitis, cancer, etc. Water pollution damages the plants and aquatic animals present in the river by reducing the oxygen content from the water. Polluted water washes the essential nutrients which plants need out of the soil and also leaves large amounts of aluminium in the soil, which can be harmful to plants. 

Wastewater and sewage are a by-product of daily life and thus produced by each household through various activities like using soap, toilets, and detergents. Such sewage contains chemicals and bacteria which are harmful to human life and environmental health. Water pollution also leads to an imbalance in our ecosystem. Lastly, it also affects the food chain as the toxins in the water bodies are consumed by aquatic animals like fish, crabs etc., and then humans consume those animals forming turmoil. 

Sometimes our tradition also becomes a cause for water pollution. Some people throw the statues of deities, flowers, pots, and ashes in rivers.

There are various standards to define water quality standards. Water meant for swimming may not be clean enough for drinking, or water meant for bathing may not be good for cooking. Therefore, there are different water standards for defined:

Stream standards- Standards that define streams, lakes, oceans or seas based on their maximum use.

Effluent standards- Define the specific standards for the level of contaminants or effluents allowed during the final discharge of those into the water bodies.

Drinking water standards- Define the level of contamination allowed in water that will be supplied for drinking or cooking in the domestic areas.

Different countries regulate their water quality standards through different acts and amendments.

While many of the solutions for water pollution need to be applied on a broader macro-level for that individual, companies, and communities can have a significant and responsible impact on the water quality. Companies, factories have to dispose of leftover chemicals and containers properly as per the product instructions. Farmers also have to reduce the use of nitrates and phosphates from fertilizers, pesticides, and contamination of groundwater. 

The Swachh Bharat Mission of the government had led to reduced groundwater contamination. Under the Namami Ganga program, the government has initiated several major projects to clean Ganga. Along with all these steps, conservation of water is the very basic and important step towards water conservation and should be followed globally, treatment of sewage before their disposal in the water bodies and using environment-friendly products that do not form toxins when dissolved in water. These are some small steps that have to be taken into consideration by every human being.

As we all know, “Water is life’s matter and matrix, mother and medium. There is no life without water.” We have to save water. We must keep the water clean. If everyone will follow their responsibility against water to protect it from getting polluted then it will be easy to get clean and healthy drinking water. Clean water is a must for us and our kids' present, future, and healthy environment. 

We cannot just live with contaminated waters filled with toxins and no oxygen. We cannot see our wildlife being destroyed and therefore, immediate steps have to be taken by groups of people to first clean the already contaminated water bodies and then keep a check on all the surrounding water bodies. Small steps by every individual can make a huge difference in controlling water pollution.

Water Pollution Prevention

Conserve Water 

Our first priority should be to conserve water. Water wasting could be a big problem for the entire world, but we are just now becoming aware of it.

Sewage Treatment 

Cleaning up waste materials before disposing of them in waterways reduces pollution on a large scale. By lowering its dangerous elements, this wastewater will be used in other sectors or in agriculture.

Usage of Eco-Friendly Materials

We will reduce the amount of pollution produced by choosing soluble products that do not alter to become pollutants.

Water contamination is the discharge of pollutants into the water body, where they dissolve, are suspended, are deposited on the bottom, and collect to the point where they hinder the aquatic ecosystem's ability to function. Water contamination is brought on by toxic compounds that easily dissolve and combine with it and come from factories, municipalities, and farms.

Healthy ecosystems depend on a complex network of organisms, including animals, plants, bacteria, and fungi, all of which interact with one another either directly or indirectly. In this article, we read about water pollution, its causes and prevention. With this, we have come to the end of our article, in case of any other doubts, feel free to ask in the comments.

FAQs on Water Pollution Essay

1. What are the effects of water pollution?

Water pollution has a great impact on human health. Water pollution kills. It's been recorded that in 2015 nearly 1.8 million people died because of water pollution. People with low income are exposed to contaminated water coming out from the industries. Presence of disease causing pathogens in drinking water are the major cause of illness which includes cholera, giardia, and typhoid. Water pollution not only affects human health but also our environment by causing algal bloom in a lake or marine environment. Water pollution also causes eutrophication which suffocates plants and animals and thus causes dead zones. Chemicals and heavy metals from industrial and municipal wastewater contaminate waterways and harm aquatic life.

2. What are the causes of Water pollution?

Water being a universal solvent is vulnerable to pollution as it dissolves more substances than any other liquid on earth. Therefore, water is easily polluted. Toxic substances from farms, towns, and factories readily dissolve into water and mix with it, resulting in water pollution. Agricultural pollution is one of the major causes of contamination in rivers and streams. The use of excessive fertilizers, pesticides, and animal waste from farms and livestock operations lets the rain wash the nutrients and pathogens—such as bacteria and viruses—into our waterways. The other major cause of water pollution is used water,  termed as wastewater which comes from our sinks, showers, toilets and from commercial, industrial, and agricultural activities. It's been reported that the world's 80% wastewater flows back into the environment without being treated or reused. Oil spills and radioactive waste also cause water pollution to a great extent.

3. How to prevent water pollution?

It is important to keep our water bodies clean so we can take the following preventive measures to prevent from water pollution:

Chemicals like bleach, paint, paint thinner, ammonia, and many chemicals are becoming a serious problem. Dumping toxic chemicals down the drain or flushing them down the toilet can cause water pollution. Thus, proper disposal is important. Also, household chemicals need to be recycled.

Avoid buying products that contain persistent and dangerous chemicals. Buying non-toxic cleaners and biodegradable cleaners and pesticides cut down on water pollution.

Prevent from pouring fats or greasy substances down the drain as it might clog the drain resulting in the dumping of waste into yards or basement which can contaminate the local water bodies.

4. What is the role of medical institutions in polluting the water?

Pharmaceutical pollution affects aquatic life and thus there is a need to take preventive measures. Consumers are responsible for winding up pharmaceutical and personal care products in lakes, rivers, and streams. There's a lot of unused and expired medication that can potentially get into the water if not disposed of properly.

5. What are the major kinds of pollution?

The three main types of pollution are air pollution, water pollution or soil pollution. Some artificial pollution is also there, such as noise pollution. Factors leading to such pollution include:

Air Pollution: Industrial emissions, fires, traffic and transportation, burning of chemical waste, etc.

Water Pollution: No proper sewage disposal, pesticides in farms leaking into water bodies, industrial waste dumped into water bodies, etc.

Soil Pollution:  Oil spills, acid rains, irresponsible disposal of trash, chemical waste, etc.

Noise Pollution: Honking of horns, construction activities, loud parties, etc.

500+ words essay on water pollution.

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

Water and Water Cycle

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

What is Water Pollution?

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

Sources of Water Pollution

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

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

Effects of Pollution of Water

The effects of Water Pollution are:

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

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

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

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

Prevention of Water Pollution

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

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

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

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

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

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.

What Causes Water Pollution and How Do We Solve it?

Water pollution is putting our health at risk. Unsafe water kills more people each year than war and all other forms of violence combined. Meanwhile, less than 1% of the Earth’s freshwater is actually accessible to us and it’s in our best interest to protect what we have, especially considering that by 2050, global demand for freshwater is expected to be one-third greater than it is now. Here are six causes of water pollution, as well as what we can do to reduce it.

Water is uniquely vulnerable to pollution because it’s able to dissolve more substances than any other liquid on Earth. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, which causes water pollution as a result.

6 Most Common Causes of Water Pollution

1. sewage and wastewater .

According to the UN , more than 80% of the world’s wastewater flows back into the environment without being treated or reused; in some least-developed countries, this figure tops 95%. Harmful chemicals and bacteria can be found in sewage and wastewater even after it’s been treated. Households release sewage and wastewater, which makes its way to the ocean, mixing with freshwater and affecting the water quality and marine life. Also, the bacteria and pathogens found in wastewater breed disease, and cause health-related issues in humans and animals. 

2. Oil Spills

Large oil spills and leaks are some of most significant causes of water pollution. These are often caused by oil drilling operations in the ocean, but nearly half of the estimated 1 million tons of oil that makes its way into marine environments each year come not from oil tankers, but from land-based sources like factories, farms and cities. In England and Wales, there are about 3,000 pollution incidents involving oil and fuel each year. Oil makes drinking water unsafe and a substantial amount of oil released into oceans or become river water pollution, will destroy marine life and the ecosystems that support them. What’s more, oil reduces the oxygen supply within the water environment.  Oil is also naturally released from under the ocean floor through fractures known as seeps.

3. Industrial Waste

Industrial waste is one of the biggest sources of water contamination. Many industrial sites produce waste in the form of toxic chemicals and pollutants, and some don’t have proper waste management systems in place. Sometimes, industrial waste is dumped into nearby freshwater systems. The toxic chemicals leached from this waste can make the water unsafe for human consumption, and they can also cause the temperature in freshwater systems to change, making them dangerous for marine life. Finally, industrial waste can cause “ dead zones ,” which are areas of water that contain so little oxygen that marine life cannot survive in them.

4. Agricultural Runoff

To protect crops from pests, farmers use pesticides, however when these substances seep into the groundwater, they can harm animals, plants and humans. Additionally, when it rains, the chemicals mix with rainwater, which flows into waterways and creates further pollution. Other agricultural processes such as uncontrolled spreading of slurries and manures, tillage and ploughing the land can also cause water pollution.

5. Marine Dumping and Plastic Pollution in the Sea

Most items collected and dumped into oceans by many countries can take anywhere from two to 200 years to decompose completely! Other sources of waste at sea include plastic and other materials blown or washed from land. Currently, about 11 million metric tons of plastic make their way into the oceans each year. Research has found that should this rate of pollution continues, the amount of ocean plastics will grow to 29 million metric tons per year by 2040. The damage to wildlife habitats and to life on land is incalculable.

6. Radioactive Waste

Radioactive waste can persist in the environment for thousands of years , making disposal a major challenge and one of the most harmful water contaminants. Radioactive waste released from facilities that create nuclear energy can be extremely harmful to the environment and must be disposed of properly; uranium, the element used in the creation of nuclear energy, is a highly toxic chemical. Accidents occur at these facilities from time to time, and toxic waste is released into the environment.

In April 2021, Japan discharged contaminated water containing radioactive materials from the damaged Fukushima nuclear plant into the sea. Though the Japanese government claims potential health risks and damage to marine life to be minimal as the waste water have been treated, close monitoring is required to ensue there are no environment effects from the water pollution.

How Can You Reduce Water Pollution?

• Reduce your plastic consumption and reuse or recycle plastic when you can. 
• Properly dispose of chemical cleaners, oils and non-biodegradable items.
• Use phosphate-free detergents – phosphates lead to algae blooms and kill fish and other aquatic animals by reducing the oxygen in the water. 
• Dispose of medical waste properly.
• Eat more organic food, which is produced without the use of pesticides.
• Cut down on your meat consumption – raising animals for meat takes lots of water for the grains and other feed they need. Furthermore, the antibiotics and solid waste are both likely to end up in groundwater and rivers.

Discharge from a Chinese fertilizer factory winds its way toward the Yellow River. Like many of the world's rivers, pollution remains an ongoing problem.

Water pollution is a rising global crisis. Here’s what you need to know.

The world's freshwater sources receive contaminants from a wide range of sectors, threatening human and wildlife health.

From big pieces of garbage to invisible chemicals, a wide range of pollutants ends up in our planet's lakes, rivers, streams, groundwater, and eventually the oceans. Water pollution—along with drought, inefficiency, and an exploding population—has contributed to a freshwater crisis , threatening the sources we rely on for drinking water and other critical needs.

Research has revealed that one pollutant in particular is more common in our tap water than anyone had previously thought: PFAS, short for poly and perfluoroalkyl substances. PFAS is used to make everyday items resistant to moisture, heat, and stains; some of these chemicals have such long half-lives that they are known as "the forever chemical."

Safeguarding water supplies is important because even though nearly 70 percent of the world is covered by water, only 2.5 percent of it is fresh. And just one percent of freshwater is easily accessible, with much of it trapped in remote glaciers and snowfields.

Water pollution causes

Water pollution can come from a variety of sources. Pollution can enter water directly, through both legal and illegal discharges from factories, for example, or imperfect water treatment plants. Spills and leaks from oil pipelines or hydraulic fracturing (fracking) operations can degrade water supplies. Wind, storms, and littering—especially of plastic waste —can also send debris into waterways.

Thanks largely to decades of regulation and legal action against big polluters, the main cause of U.S. water quality problems is now " nonpoint source pollution ," when pollutants are carried across or through the ground by rain or melted snow. Such runoff can contain fertilizers, pesticides, and herbicides from farms and homes; oil and toxic chemicals from roads and industry; sediment; bacteria from livestock; pet waste; and other pollutants .

Finally, drinking water pollution can happen via the pipes themselves if the water is not properly treated, as happened in the case of lead contamination in Flint, Michigan , and other towns. Another drinking water contaminant, arsenic , can come from naturally occurring deposits but also from industrial waste.

Freshwater pollution effects

Water pollution can result in human health problems, poisoned wildlife, and long-term ecosystem damage. When agricultural and industrial runoff floods waterways with excess nutrients such as nitrogen and phosphorus, these nutrients often fuel algae blooms that then create dead zones , or low-oxygen areas where fish and other aquatic life can no longer thrive.

Algae blooms can create health and economic effects for humans, causing rashes and other ailments, while eroding tourism revenue for popular lake destinations thanks to their unpleasant looks and odors. High levels of nitrates in water from nutrient pollution can also be particularly harmful to infants , interfering with their ability to deliver oxygen to tissues and potentially causing " blue baby syndrome ." The United Nations Food and Agriculture Organization estimates that 38 percent of the European Union's water bodies are under pressure from agricultural pollution.

Globally, unsanitary water supplies also exact a health toll in the form of disease. At least 2 billion people drink water from sources contaminated by feces, according to the World Health Organization , and that water may transmit dangerous diseases such as cholera and typhoid.

Freshwater pollution solutions

In many countries, regulations have restricted industry and agricultural operations from pouring pollutants into lakes, streams, and rivers, while treatment plants make our drinking water safe to consume. Researchers are working on a variety of other ways to prevent and clean up pollution. National Geographic grantee Africa Flores , for example, has created an artificial intelligence algorithm to better predict when algae blooms will happen. A number of scientists are looking at ways to reduce and cleanup plastic pollution .

There have been setbacks, however. Regulation of pollutants is subject to changing political winds, as has been the case in the United States with the loosening of environmental protections that prevented landowners from polluting the country’s waterways.

Anyone can help protect watersheds by disposing of motor oil, paints, and other toxic products properly , keeping them off pavement and out of the drain. Be careful about what you flush or pour down the sink, as it may find its way into the water. The U.S. Environmental Protection Agency recommends using phosphate-free detergents and washing your car at a commercial car wash, which is required to properly dispose of wastewater. Green roofs and rain gardens can be another way for people in built environments to help restore some of the natural filtering that forests and plants usually provide.

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 Possible Solutions Expository Essay

Introduction, causes and effects of water pollution, possible solutions for water pollution.

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

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

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

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

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

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

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

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

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

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

What Is Water Pollution?

Watch this brief, video picture of practice that captures everyday classroom life and provides real-life examples of how students learn and think about freshwater topics.

Earth Science

When asked what water pollution is, most students can readily explain pollution as trash thrown away by humans that enters our water. Students can readily identify items visible to the naked eye, such as cigarette butts, plastic bottles, and bags. This type of debris is certainly a water-pollution problem. However, when students are asked about other sources of water pollution, they may be lost or not able to identify invisible pollutants. Chemical released by manufacturing, cars, and lawns and farms are large contributors to water pollution but can be hard for students to identify because they may not be visible, or the source of the pollution is not easily connected to the area that is impacted. For example, yard fertilizers and pesticides run into storm drains and simply "disappear" from students' world. Likewise, if students are asked how pollution gets into water, they may point to littering but not identify different types of runoff. It is important that students understand that there are many pollutants that get into the water—in different ways—so they can better understand how to prevent pollution from entering the water systems in the first place. Watch this video of 6th grade students in San Diego, California—a coastal community. The purpose of this classroom video is to see students share their ideas about water pollution. For additional classroom context, video analysis, and reflection opportunities, read the Picture of Practice page for "What Is Water Pollution?" in the Earth's Freshwater Educator Guide , page 80.

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

Water Pollution Essay

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

100 Words Essay On Water Pollution

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

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

200 Words Essay On Water Pollution

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

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

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

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

500 Words Essay On Water Pollution

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

Causes Of Water Pollution

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

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

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

How To Manage Water Pollution

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

Real-Life Experience

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

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

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

Rural water crisis vital to health of the planet | Opinion

As we celebrate Earth Day 2024 and think about the health of the blue planet, there is no other crisis more important than where land meets water in rural America. 

Water issues there have escalated into a dire situation that demands immediate attention. The groundwater we count on to supply America’s rural residents is facing a critical risk of overextraction and contamination. Surface waters are impacted by overapplication of fertilizers, as well as by septic tanks, sludge and animal manure. The intricate water and wastewater systems in rural areas are profoundly influenced by climate change and land use, emphasizing the urgent need for innovation and modernization to prevent catastrophic outcomes.

On this Earth Day, the call for action is clear: It is imperative for national leaders and citizens alike to take decisive steps toward addressing this emergency.

Water’s importance transcends mere consumption. It is indispensable for food production, recreation, and ecosystem health, especially in rural America where groundwater wells and septic systems form the backbone of daily life. The water systems in rural areas are intricate, encompassing a diverse range of features including tile drains, drainage ditches, small tributaries, ponds and lakes. These systems interface with both ground and surface waters on a larger scale and are profoundly influenced by climatic conditions including temperature changes, floods, droughts and extreme weather events.

Water quality and food safety are at risk not only from pathogens and forever chemicals, but excess nitrate (associated with new risks such as thyroid cancer) and antibiotic resistant bacteria. Animal fecal waste (manure) which is neither monitored or managed for pathogens is now a larger source of nutrient pollution and zoonotic diseases (estimated at 1.4 billion tons of manure per year in the U.S. ). 

The stakes are high for 46 million people who live in rural communities in the US. Their health and economic vitality is of upmost importance. These non-metropolitan areas provide 10% of the country's GDP and in 2022, approximately $1.420 trillion from agriculture, food and related industries, and $223.5 billion from America's farms. 

Not to mention the economic impact associated with recreation and retirement destinations at the margins of larger cities such as in the Great Lakes region. For example, U.S. Fish and Wildlife Service estimates that angling generates $7 billion annually . When an individual beach is closed, seasonal aggregate losses were estimated at $360 thousand to $24 million.

Water and fecal waste management have unfortunately been overlooked within the USDA Strategic Plan for Fiscal Years 2022–2026. Although Goals 1 and 4, focusing on "Addressing Climate Change and Maintaining a Safe Food Supply," touch upon aspects of rural water systems and public health, there is a clear need for additional objectives in this area. Climate change exacerbates issues such as water scarcity and over-pumping of groundwater, while precipitation runoff and irrigation patterns contribute to the spread of pollutants and microorganisms. It's crucial to recognize that land management practices are at the root of these risks. However, despite the challenges, viable solutions exist and must be pursued to address these pressing issues effectively.

The State of Michigan has emerged as a leader in this realm, demonstrating the potential for science and technology to revolutionize water quality management. By modernizing infrastructure and embracing precision agriculture, alongside fostering public-private partnerships, significant strides can be made toward sustainable water management.

However, efforts to mitigate pollution and protect water quality must be intensified as poverty, inadequate water infrastructure and food insecurity are now becoming critical issues in the US.  The time is now, given the Infrastructure Investment and Jobs Act and climate initiatives.  This entails implementing best management practices in agriculture to reduce runoff and minimize chemical inputs, enforcing regulations to prevent industrial pollution, and promoting sustainable land use practices that preserve water resources in the coming years.

We support two new goals for addressing water in rural communities:

• Improve the monitoring of ground and surface water quality using advanced and modern tools while building spatial and temporal data bases.
• Address innovative approaches for controlling fecal pollution from septic systems, and manure and farm-based stormwaters along with resource recovery enhancing the circular economy.

Only by prioritizing investment in infrastructure, implementing and documenting pollution prevention measures and fostering community engagement can we begin to address the root causes of the rural water crisis. Only through concerted and collaborative action can we safeguard the health of our nation and secure a sustainable future for generations to come. The time to act is now; the health of our nation and the sustainability of our future depend on it.

Negotiators from around the world are gathering in Ottawa this week to try to hash out the text for a new international treaty on plastic pollution . The delegates are short on time : the treaty process, which started in 2022, is due to be finalized this December. But they are not short on science, thanks to a surge of new data and models from researchers aiming to inform the talks.

“I’ve never seen a new diplomatic process move this fast and science trying to catch up,” says Margaret Spring, a legal specialist and conservation manager at the Monterey Bay Aquarium in California.

Landmark treaty on plastic pollution must put scientific evidence front and centre

Observers hope the treaty will cover all aspects of plastic production and disposal ; it could, for example, limit how much plastic is produced or set up financial mechanisms to aid waste management. But the treaty process has been hindered by disagreement , with some member states arguing against tough measures such as caps on the production of virgin plastic. It is unclear whether and when a treaty will be agreed.

In the run-up to the final negotiations, researchers have been publishing more reports, data sets and models about plastics than ever before. “I definitely feel that sense of urgency and rush,” says ecologist Douglas McCauley at the University of California, Santa Barbara, who is attending the negotiations. Researchers have also organized groups, such as the Scientists’ Coalition for an Effective Plastics Treaty, to advance the profile of scientific evidence at the meetings. Nature spotlights some key statistics on the outcome of proposed policies and the effects of plastic waste.

122 million tonnes of mismanaged plastic waste

The treaty was originally conceived as a mechanism to end plastic pollution, which is sometimes taken to mean driving the amount of ‘mismanaged waste’ to zero by 2040. Mismanaged waste is plastic that isn’t recycled or disposed of in a well-managed landfill or incinerator, but rather ends up loose in the environment or burned in an open pit.

Annual production of plastics has grown exponentially, from about 2 million tonnes in 1950 to 460 million tonnes in 2019 (current levels are on track to triple by 2060). Mismanaged waste is hard to measure, given the vast number of sources, but McCauley estimates that about 74 million tonnes are currently produced each year. His modelling suggests that by 2050 this figure will reach 122 million tonnes per year, under business-as-usual projections. Unless policies change, the peak of mismanaged plastic waste “is nowhere yet in sight”, he says.

Buried microplastics complicate efforts to define the Anthropocene

McCauley’s team and others 1 have modelled how policies that could be included in the treaty would affect waste. Their work shows that getting close to the ‘zero waste’ goal requires a mix of strong measures, including both downstream efforts (such as increasing recycling ) and upstream ones (such as capping virgin-plastic production). “You have to do everything,” says Spring, who chairs an expert group on plastic for the International Science Council, a Paris-based coalition of scientific agencies, that is providing science-based advice on the treaty’s draft language.

The models also show that a cap on plastic production — a particularly contentious topic during the negotiations — is one of the most powerful levers for cutting pollution.

McCauley and his colleagues used their modelling results to create an online tool to help negotiators to understand the implications of their choices. With a single mouse click, delegates can find out how a particular bundle of policies affects waste levels. A suite of 11 policies that negotiators are discussing could by 2050 whittle the amount of mismanaged waste down to 41 million tonnes.

6.78 gigatonnes of greenhouse gases

A new report from environmental-policy researcher Nihan Karali and her colleagues at Lawrence Berkeley National Laboratory in California concludes that plastic production generated the equivalent of 2.24 gigatonnes of carbon dioxide in 2019, mainly from the energy-intensive process of extracting and refining the fossil fuels used to generate the petrochemicals that make up most virgin plastic 2 .

The report projects that those emissions will triple to 6.78 gigatonnes by 2050 if plastic production grows by 4% each year — a figure similar to annual production growth since 2010. That means that, over the next 25 years, cumulative plastics production alone would gobble up more than a quarter of the total carbon that can be emitted if the Earth’s temperature is to rise less than 1.5° C above pre-industrial levels, the preferred goal of the landmark Paris agreement on climate change .

McCauley’s model shows that the same 11 policies that could slash mismanaged plastic waste could cut greenhouse-gas emissions in 2050 by 26% below business-as-usual projections (see ‘Crackdown on plastic has climate benefits’). But McCauley cautions that his group’s projections do not include estimates of the emissions produced by any materials used to replace plastic.

4,200 chemicals deemed hazardous

An individual plastic typically contains hundreds of chemicals — many of which are toxic and can leach out — that make the material more flexible, water repellent, flame retardant or resistant to ultraviolet light. Last month, researchers released a report listing 16,000 chemicals associated with plastics , of which they found at least to be 4,200 hazardous.

The most comprehensive report on health effects from plastics thus far is ‘The Minderoo-Monaco Report on Plastics and Human Health’ 3 , which a global team of scientists published last year in Annals of Global Health . That report, which Spring worked on, estimates that in 2015 the health costs of disease and disability caused by plastic-associated chemicals were more than US$920 billion in the United States alone. New work is helping to find specific health links, says Spring: a study published in February of some 250 people undergoing surgery showed that nano- and microplastics in carotid-artery blockages were linked to increased risk of heart attacks, strokes and death 4 .

“A number of groups are saying you must, must, must focus on public health,” says Spring.

Revealed: Tyson Foods dumps millions of pounds of toxic pollutants into US rivers and lakes

Nitrogen, phosphorus, chloride, oil and cyanide among the 371m lb of pollutants released by just 41 plants in five years

Tyson Foods dumped millions of pounds of toxic pollutants directly into American rivers and lakes over the last five years, threatening critical ecosystems, endangering wildlife and human health, a new investigation reveals.

Nitrogen, phosphorus, chloride, oil and cyanide were among the 371m lb of pollutants released into waterways by just 41 Tyson slaughterhouses and mega processing plants between 2018 and 2022.

According to research by the Union of Concerned Scientists (UCS), the contaminants were dispersed in 87bn gallons of wastewater – which also contains blood, bacteria and animal feces – and released directly into streams, rivers, lakes and wetlands relied on for drinking water, fishing and recreation. The UCS analysis , shared exclusively with the Guardian, is based on the most recent publicly available water pollution data Tyson is required to report under current regulations.

The wastewater was enough to fill about 132,000 Olympic-size pools, according to a Guardian analysis.

The water pollution from Tyson, a Fortune 100 company and the world’s second largest meat producer, was spread across 17 states but about half the contaminants were dumped into streams, rivers, lakes and wetlands in Nebraska, Illinois and Missouri.

The midwest is already saturated with nitrogen and phosphorus from industrial agriculture – factory farms and synthetics fertilizers – contributing to algal blooms that clog critical water infrastructure, exacerbate respiratory conditions like asthma, and deplete oxygen levels in the sea causing marine life to suffocate and die.

Yet the UCS research is only the tip of iceberg, including water pollution from only one in three of the corporation’s slaughterhouses and processing plants, and only 2% of the total nationwide.

The current federal regulations set no limit for phosphorus, and the vast majority of meat processing plants in the US are exempt from existing water regulations – with no way of tracking how many toxins are being dumped into waterways.

“There are over 5,000 meat and poultry processing plants in the United States, but only a fraction are required to report pollution and abide by limits. As one of the largest processors in the game, with a near-monopoly in some states, Tyson is in a unique position to treat even hefty fines and penalties for polluting as simply the cost of doing business. This has to change,” said the UCS co-author Omanjana Goswami.

The findings come as the Environmental Protection Agency (EPA) must decide between robust new regulations that experts say would better protect waterways, critical habitat and downstream communities from polluting plants – or opt for weaker standards preferred by the powerful meat-processing industry.

A 2017 lawsuit by environmental groups has forced the EPA to update its two-decade-old pollution standards for slaughterhouses and animal rendering facilities, and the new rule is expected by September 2025. The agency has said that it is leaning towards the weakest option on the table, which critics say will enable huge amounts of nitrates, phosphorus and other contaminants to keep pouring into waterways.

“The current rule is out of date, inadequate and catastrophic for American waterways, and highlights the way American lawmaking is subject to industry capture,” said Dani Replogle, an attorney at Food and Water Watch. “The nutrient problem in the US is at catastrophic levels … it would be such a shame if the EPA caves in to industry influence.”

The meat-processing industry spent $4.3m on lobbying in Washington in 2023, of which Tyson accounted for almost half ($2.1m), according to political finance watchdog Open Secrets. The industry has made $6.6m in campaign donations since 2020, mostly to Republicans, with Tyson the biggest corporate spender.

“We can be sure Tyson and other big ag players will object to efforts to update pollution regulations, but the EPA should listen to communities whose wells, lakes, rivers and streams have been contaminated and put people over corporate profits,” said Goswami.

“Meat and poultry companies spend hundreds of millions of dollars to comply with EPA’s effluent limitations guidelines,” said Sarah Little from the North American Meat Institute, a trade association representing large processors like Tyson. “EPA’s new proposed guidelines will cost over $1bn and will eliminate 100,000 jobs in rural communities.”

Tyson did not respond to repeated requests for comment.

The American Association of Meat Processors said the EPA’s one-size-fits-all approach could put its small, family-owned members out of business.

Nebraska is a sparsely populated rural state dominated by agriculture – an increasingly consolidated corporate industry which wields substantial control over the economy and politics, as well as land and water use.

Millions of acres in Nebraska are dedicated to factory farming, with massive methane-emitting concentrated animal feeding operations (Cafos) scattered among fields of monocropped soybean, corn and wheat – grown predominantly for animal feed and ethanol. Only a tiny fraction of arable land is dedicated to sustainable agriculture or used to grow vegetables or fruits.

Tyson’s five largest plants in Nebraska dumped more than 111m lb of pollutants into waterways between 2018 and 2022, accounting for a third of the nationwide total. This included 4m lb of nitrates – a chemical that can contaminate drinking water, cause blood disorders and neurological defects in infants, as well as cancers and thyroid disease in adults.

Tyson’s largest plant is located in Dakota City on the Missouri river – America’s longest waterway which stretches 2,300 miles across eight states before joining the Mississippi. It’s a sprawling beef facility, which generates a nauseating stench that wafts over neighboring South Sioux city, known locally as sewer city, where many plant workers live. (Another beef processing plant is located next to Tyson.)

Earlier this month, the Guardian saw multiple trucks waiting to offload cattle for slaughter – after which the carcasses are rendered, processed and packaged in different parts of the facility. The plant produces vast quantities of wastewater which is stored (and treated) in lagoons on the riverbank, before being released into the Missouri river which provides drinking water for millions of people.

The Dakota City plant is a major local employer and Tyson’s single largest polluter, dumping 60m lb of contaminants into waterways between 2018 and 2022, according to UCS analysis.

“This Tyson plant helped put me through college and supports a lot of migrant workers, but there’s a dark side like the water and air pollution that most people don’t pay attention to because they’re just trying to survive,” said Rogelio Rodriguez, a grassroots organizer with Conservation Nebraska, which is part of a coalition pushing for stronger state protections for meat processing plant workers.

“If regulations are lax, corporations have a tendency to push limits to maximize profits, we learnt that during Covid,” said Rodriguez, whose family works at the plant. A deadly Covid outbreak at the Dakota City plant in April 2020 sickened 15% of the workforce and led to substantial community spread.

A few miles south of the Dakota City Tyson plant, the Winnebago tribe is slowly recuperating and reforesting their land, as well as transitioning to organic farming.

“We’re investing a lot of money to look after the water and soil on our lands because it’s the right thing to do, yet a few miles north the Tyson plant lets all this pollution go into the river. Water is our most important resource, and the Missouri river is very important to our culture and people,” said Aaron LaPointe, a Winnebago tribe member who runs Ho-Chunk Farms.

The water problem – and lack of accountability – goes beyond Tyson.

Last year Governor Jim Pillen, whose family owns one of America’s largest pork companies, was widely criticized for calling a Chinese-born journalist at Flatwater Free Press a “communist” after she exposed serious water quality violations at his hog farms. Earlier this month, the Nebraska supreme court ruled that the state environmental agency could charge the same investigative news outlet tens of thousands of dollars for a public records request about nitrates.

Big ag’s influence on state politics is “endemic”, according to Gavin Geis from Common Cause Nebraska, a non-partisan elections watchdog.

“The big money spent on lobbying and campaigns by corporate agriculture has played a major role in resisting stronger regulation – despite clear signals such as high levels of nitrates in our groundwater and cancers in rural communities that we need more oversight for farmers across the board,” said Geis.

“We’ve created a system with no accountability that doesn’t protect our ecosystem – which includes the land, water and people of Nebraska,” said Graham Christensen, a regenerative farmer and founder of GC Resolve, a communication and consulting firm. “The political capture is harming our rural communities, we’re in the belly of the beast and need help from federal regulators.”

Indigenous Americans lived and farmed sustainably along the Missouri River until white colonial settlers forcibly displaced tribes, and eventually dammed the entire river system – mostly for energy and industrial agriculture. Today, major river systems like the Missouri River – and its communities – face multiple, overlapping threats from dams, the climate crisis, overuse and pollution.

Oxygen depleting contaminants like nitrogen and phosphorus from Tyson plants in the midwest have been shown to travel along river-to-river pathways, causing fish kills and contributing to dead zones in the Gulf of Mexico. When the river is drier due to drought or high temperatures, pollutants become more concentrated and can form sediments – which are then dislodged during floods and taken miles downstream.

Global heating is making extreme weather increasingly common, and as droughts dry up underground aquifers, tribes will probably need to turn to the Missouri for drinking water, according to Tim Grant, director of environmental protection for the Omaha tribe. “We’re very concerned about what’s in the river, it’s an important part of our culture and traditions,” said Grant, who has started testing the fish for toxins.

The UCS research also found Tyson plants located close to critical habitats for endangered or threatened species – including the whooping crane, the tallest and among the rarest birds in North America.

There are currently only 500 or so wild whooping cranes – up from 20 birds in the 1940s – which stop to feed and rest along a shallow stretch of the Platte River, a tributary of the Missouri in central Nebraska, as they migrate between the Texas Gulf coast and Canada. The majestic white birds feed in the cornfields that surround the Platte River, outnumbered by the slate gray sandhill cranes that also migrate through Nebraska each spring.

Tyson’s sprawling Lexington slaughterhouse and beef processing plant is situated less than two miles from the Platte River – among four federally designated critical habitats considered essential to conservation of the whooping crane.

“The cumulative effects of exposure to these industrial toxins could pose a long-term threat to the cranes’ food sources, reproductive success and resilience as a species,” said George Cunningham, a retired aquatic ecologist and Missouri River expert at Sierra Club Nebraska.

“Poor environmental regulation is down to the stranglehold industrial agriculture has on politics – at every level. It’s about political capture.”

New rules will slash air, water and climate pollution from U.S. power plants

Four rules from the environmental protection agency will reduce harmful emissions from gas- and coal-fired power plants across the country. legal challenges are likely..

The Environmental Protection Agency on Thursday finalized an ambitious set of rules aimed at slashing air pollution, water pollution and planet-warming emissions spewing from the nation’s power plants.

If fully implemented, the rules will have enormous consequences for U.S. climate goals, the air Americans breathe and the ways they get their electricity. The power sector ranks as the nation’s second-largest contributor to climate change, and it is a major source of toxic air pollutants tied to various health problems.

Before the restrictions take effect, however, they will have to survive near-certain legal challenges from Republican attorneys general, who have been emboldened by the Supreme Court’s skepticism of expansive environmental regulations.

Another wild card is the November election, which could hand the White House back to former president Donald Trump , who has pledged to scrap dozens of President Biden’s green policies if he returns to office.

One of the most significant rules will limit greenhouse gas emissions from new natural gas-fired power plants and existing coal-fired power plants. It will push all existing coal plants by 2039 to either close or capture 90 percent of their carbon dioxide emissions at the smokestack.

A second regulation will reduce releases of mercury and other toxic air pollutants from the smokestacks of coal plants nationwide. Exposure to mercury, a powerful neurotoxin, can cause serious health effects , especially for developing fetuses and children.

A third rule will expand federal oversight of coal ash , the waste from coal plants that often contains a mix of chemicals linked to increased cancer risk. A fourth will limit the levels of toxic metals in the wastewater that coal plants can discharge into rivers, lakes, streams and other waterways.

Each rule will yield huge benefits for public health and the planet, according to the EPA. The greenhouse gas standards alone will prevent up to 1,200 premature deaths, 870 hospital visits and 1,900 asthma cases in 2035, the agency said. They will also reduce carbon emissions through 2047 by 1.38 billion tons — equivalent to the annual emissions of 328 million gasoline-powered cars.

Together, the rules represent the culmination of an aggressive plan that EPA Administrator Michael Regan first outlined in 2022 . Speaking to an energy industry conference in Houston that year, Regan promised an array of regulatory actions to tackle pollution from power plants, which he said often hits poor and minority neighborhoods the hardest.

On Thursday, Regan announced the final rules during an event at Howard University, a historically Black college.

“More than 70 percent of the nation’s coal and natural gas plants are located in communities of color or low-income communities, making their health impacts and outcomes disproportionately worse,” he said. “Folks, this is simply unacceptable.”

West Virginia Attorney General Patrick Morrisey (R) has already promised to sue over the EPA’s greenhouse gas limits for power plants. He has argued that the limits violate the Supreme Court’s 2022 decision in West Virginia v. EPA , in which the conservative majority found that the agency lacks the authority to force utilities to shutter coal plants and switch to renewable energy generation.

Sen. Shelley Moore Capito (R-W.Va.) on Thursday said she plans to introduce a resolution to repeal the greenhouse gas standards. “The administration has chosen to press ahead with its unrealistic climate agenda that threatens access to affordable, reliable energy for households and employers across the country,” she said in a statement.

Jeff Holmstead, a partner at the law and lobbying firm Bracewell LLP and a former top EPA official under President George W. Bush, said legal or political challenges could scuttle the regulation.

“I have a hard time believing this will be upheld in court,” he said. “And if there is to be a Republican administration in 2025, it would be pretty easy for them to just undo the rule.”

Jody Freeman, who directs the Environmental and Energy Law Program at Harvard Law School, said she thinks the rule is on solid legal ground, because EPA lawyers crafted it to comply with the 2022 decision and the Clean Air Act. But it is difficult to predict what the conservative justices will decide, she said.

“The Supreme Court will do what it wants, and it’s shown a particular hostility to EPA rules,” Freeman said.

Putting guardrails on gas

If fully implemented, the greenhouse gas standards could have the greatest impact in the Southeastern United States, where many utilities are planning for a boom in gas plants to meet explosive power demand fueled by electricity-hungry data centers and clean-technology factories.

In North Carolina, for instance, Duke Energy has argued that a new gas plant is necessary to meet “unprecedented” energy needs. Duke spokeswoman Kaitlin Kirshner said in a statement that “the final rule presents significant challenges to customer reliability and affordability.”

Yet a recent report by Energy Innovation, a climate think tank, found that utilities can reliably meet surging energy demand without new gas generation. The report warned that new gas plants could become “stranded assets” as the country transitions to cleaner energy, and the costs could be passed down to utility customers.

Charles Harper, power sector senior policy lead at Evergreen Action, an environmental group, said utilities are fomenting fear about power demand to justify plans that jeopardize the climate and consumers.

“These gas plants are a potential carbon bomb that could make U.S. climate goals unattainable,” Harper said. “They’re one of the most expensive technologies that they can charge their customers for, but there are so many low-cost alternatives available with clean energy.”

EPA officials strengthened the emissions limits for new gas plants compared with the proposed rule released last year. The final rule will apply to new large gas plants that operate more than 40 percent of the time, rather than those that operate 50 percent of the time, which The Washington Post first reported earlier this month.

In another notable change, the final rule will no longer assume that new gas plants can switch to low-emissions hydrogen to comply. The EPA will still specify that utilities can use carbon capture technology , which sucks carbon dioxide from power plant smokestacks and stores it deep underground. Some environmentalists worry the technology, which has failed to deliver in several prominent trials, could prolong the life of fossil fuel infrastructure for decades.

EPA officials announced in February that the rule would only apply to new gas plants, not existing ones. The agency probably won’t finalize emissions standards for existing gas plants until after November, so their fate may rest on the outcome of the 2024 election .

Cracking down on coal

The other three rules will marshal the full powers of the federal government to clamp down on pollution billowing from coal plants’ smokestacks, waste dumps and wastewater discharges.

The United States is already moving away from coal , which has struggled to compete economically with cheaper gas and renewable energy. U.S. coal output tumbled 36 percent from 2015 to 2023, according to the Energy Information Administration . The Sierra Club’s Beyond Coal campaign contends that 382 coal-fired power plants have closed down or proposed to retire, with 148 remaining.

Yet these remaining coal plants rank as the country’s largest source of mercury pollution, affecting hundreds of families and communities downwind. On Thursday, the EPA finalized the most stringent update to mercury limits for these plants since the Obama administration first issued Mercury and Air Toxics Standards in 2012. The agency estimated the rule will reduce by more than two-thirds the mercury emissions from plants that burn lignite, also known as brown coal.

Rich Nolan, president and chief executive of the National Mining Association, said in a statement that the Biden administration seems bent on shuttering coal plants before the end of their useful life. “For the last three years, the administration has methodically developed and executed a comprehensive strategy to force the closure of well-operating coal plants,” he said.

But Patrice Tomcik, national field director for the advocacy group Moms Clean Air Force, cheered the updated mercury limits as long overdue. Tomcik grew up two miles downwind from the Cheswick Generating Station, a coal plant in southwestern Pennsylvania that shuttered in 2022. As a child, she watched plumes from the smokestack float over the river toward her school playground, and she missed many school days because of chronic bronchitis. As an adult, she still lives in the area and worries about the health of her son, a cancer survivor.

“I recognize I can’t control the air my son breathes, and I really rely on EPA to do their job,” Tomcik said.

Tomcik and other advocates also hailed a separate regulation that will boost federal oversight of hundreds of coal ash dumps. Research suggests that the vast majority of these sites have leaked toxic chemicals such as arsenic and chromium into nearby groundwater.

Lisa Evans, an attorney specializing in hazardous waste litigation at the environmental law firm Earthjustice, said the rule will require monitoring and cleanup at about 700 additional coal ash dump sites that were exempted from the Obama administration’s 2015 regulation.

“This is a watershed moment,” Evans said on a call with reporters. “Industry fought long and hard to avoid spending a dime to clean up their toxic pollution. That ends today.”

Biden-Harris Administration Finalizes Suite of Standards to Reduce Pollution from Fossil Fuel-Fired Power Plants

Four final rules deliver on the Biden-Harris Administration’s day-one commitment to lead on climate action and to protect all communities from pollution

April 25, 2024

WASHINGTON – Today, April 25, the U.S. Environmental Protection Agency announced a suite of final rules to reduce pollution from fossil fuel-fired power plants in order to protect all communities from pollution and improve public health without disrupting the delivery of reliable electricity. These rules, finalized under separate authorities including the Clean Air Act, Clean Water Act, and Resource Conservation and Recovery Act, will significantly reduce climate, air, water, and land pollution from the power sector, delivering on the Biden-Harris Administration’s commitment to protect public health, advance environmental justice, and confront the climate crisis.

By announcing these final rules at the same time, EPA is following through on the commitment that Administrator Michael S. Regan made to industry stakeholders at CERAWeek 2022 to provide regulatory certainty as the power sector makes long-term investments in the transition to a clean energy economy. The standards are designed to work with the power sector’s planning processes, providing compliance timelines that enable power companies to plan in advance to meet electricity demand while reducing dangerous pollution.

“Today, EPA is proud to make good on the Biden-Harris Administration’s vision to tackle climate change and to protect all communities from pollution in our air, water, and in our neighborhoods,” said EPA Administrator Michael S. Regan. “By developing these standards in a clear, transparent, inclusive manner, EPA is cutting pollution while ensuring that power companies can make smart investments and continue to deliver reliable electricity for all Americans.”

“This year, the United States is projected to build more new electric generation capacity than we have in two decades – and 96 percent of that will be clean,” said President Biden’s National Climate Advisor Ali Zaidi. “President Biden’s leadership has not only sparked an unprecedented expansion in clean electricity generation, his leadership has also launched an American manufacturing renaissance. America is now a magnet for private investment, with hundreds of billions of dollars committed and 270,000 new clean energy jobs created. This is how we win the future, by harnessing new technologies to grow our economy, deliver environmental justice, and save the planet for future generations.”

The suite of final rules includes:

• A final rule for existing coal-fired and new natural gas-fired power plants that would ensure that all coal-fired plants that plan to run in the long-term and all new baseload gas-fired plants control 90 percent of their carbon pollution.  
• A final rule strengthening and updating the Mercury and Air Toxics Standards (MATS) for coal-fired power plants, tightening the emissions standard for toxic metals by 67 percent and finalizing a 70 percent reduction in the emissions standard for mercury from existing lignite-fired sources. 
• A final rule to reduce pollutants discharged through wastewater from coal-fired power plants by more than 660 million pounds per year, ensuring cleaner water for affected communities, including communities with environmental justice concerns that are disproportionately impacted.
• A final rule that will require the safe management of coal ash that is placed in areas that were unregulated at the federal level until now, including at previously used disposal areas that may leak and contaminate groundwater.

Delivering Public Health Protections for Communities, Providing Regulatory Certainty for the Industry, and Ensuring the Power Sector Can Provide Reliable Electricity for Consumers

Finalizing these four rules delivers on the Administration’s commitment to providing health protections for all communities, including communities with environmental justice concerns, many of which are located near power plants. At the same time, EPA is providing a predictable regulatory outlook for power companies, including opportunities to reduce compliance complexity, and clear signals to create market and price stability. Administrator Regan outlined this approach in 2022 when he committed to transparency and open dialogue so that state and federal energy regulators, power companies, and grid operators have clear information on which to base decisions.

EPA conducted regulatory impact analyses for each rule, showing that this suite of standards will deliver hundreds of billions of dollars in net benefits. EPA also performed a sensitivity analysis exploring the combined effect on the power sector of the carbon pollution, air toxics, and water rules, as well as EPA’s recent rules for the transportation sector. The projections regarding changes in electricity supply and demand align with recent reports from the Department of Energy (DOE) and National Renewable Energy Laboratory and peer-reviewed research in showing that the sector can meet growing demand for electricity and provide reliable, affordable electricity at the same time as it reduces pollution in accordance with these rules to protect health and the planet.

With the announcement today, the power sector can make planning decisions with a full array of information. In fact, the agency’s analysis indicates that issuing these rules at the same time is likely to create more efficiency for facilities that are now able to evaluate compliance steps together rather than only for each rule in isolation. Therefore, adding the cost of the rules modeled independently would likely reflect an overestimate of total costs.

“The new rules to clean up air pollution from power plants are good news for everyone, especially if there is a power plant near where you work, live or study. The American Lung Association applauds Administrator Regan and the entire team of professionals at the EPA for their resolute commitment to public health and environmental justice,” said Harold Wimmer, President and CEO of the American Lung Association. “Burning fossil fuels in power plants harms people’s lungs, makes kids sick and accelerates the climate crisis. The stronger clean air and climate protections will save lives.”

“These rules call on utilities and states to be full partners in making this transition fair for energy workers and communities,” said BlueGreen Alliance Executive Director Jason Walsh. “It also complements the historic federal investments made by the Biden-Harris administration and the previous Congress, which provide a toolbox of critical investments targeted to the workers and communities experiencing the economic impacts of energy transition.”

Stronger Carbon Pollution Standards for New Gas and Existing Coal Power Plants

EPA’s final Clean Air Act standards for existing coal-fired and new natural gas-fired power plants limit the amount of carbon pollution covered sources can emit, based on proven and cost-effective control technologies that can be applied directly to power plants. The regulatory impact analysis projects reductions of 1.38 billion metric tons of carbon pollution overall through 2047, which is equivalent to preventing the annual emissions of 328 million gasoline cars, or to nearly an entire year of emissions from the entire U.S. electric power sector. It also projects up to $370 billion in climate and public health net benefits over the next two decades.

The rule addresses existing coal-fired power plants, which continue to be the largest source of greenhouse gas emissions from the power sector, and ensures that new natural gas combustion turbines, some of the largest new sources of greenhouse gases being built today, are designed using modern technologies to reduce climate pollution.

The climate and health benefits of this rule substantially outweigh the compliance costs. In 2035 alone, the regulatory impact analysis estimates substantial health co-benefits including:

• Up to 1,200 avoided premature deaths
• 870 avoided hospital and emergency room visits
• 1,900 avoided cases of asthma onset
• 360,000 avoided cases of asthma symptoms
• 48,000 avoided school absence days
• 57,000 lost workdays

The final emission standards and guidelines will achieve substantial reductions in carbon pollution at reasonable cost. The best system of emission reduction for the longest-running existing coal units and most heavily utilized new gas turbines is based on carbon capture and sequestration/storage (CCS) – an available and cost-reasonable emission control technology that can be applied directly to power plants and can reduce 90 percent of carbon dioxide emissions from the plants.

Lower costs and continued improvements in CCS technology, alongside tax incentives from President Biden’s Inflation Reduction Act that allow companies to largely offset the cost of CCS, represent recent developments in emissions controls that informed EPA’s determination of what is technically feasible and cost-reasonable. The Bipartisan Infrastructure Law also includes billions of dollars to advance and deploy CCS technology and infrastructure. EPA projects that the sector can comply with the standards with negligible impact on electricity prices, thanks to cost declines in CCS and other emissions-reducing technologies. EPA analysis also finds that power companies can comply with the standards while meeting grid reliability, even when considering increased load growth.

The final rule includes requirements to help ensure meaningful engagement with affected stakeholders, including communities with environmental justice concerns, overburdened by pollution and climate change impacts, as well as the energy communities and workers who have powered our nation for generations. The standard also requires states to provide transparent data on compliance pathways and timelines through the state planning process, ensuring that workers and communities have the best-available information to plan for changes in the sector. President Biden’s Interagency Working Group on Coal and Power Plant Communities and Economic Revitalization has identified historic resources for energy communities to invest in infrastructure, deploy new technologies that can help clean up the electric power sector, support energy workers, and spur long-term economic revitalization. The final rule also follows guidance from the Council on Environmental Quality to ensure that deployment of CCS technologies is done in a responsible manner that incorporates the input of communities and reflects the best available science.

In addition to finalizing these rules, EPA has opened a non-regulatory docket and issued framing questions to gather input about a comprehensive approach to reduce GHG emissions from the entire fleet of existing gas combustion turbines in the power sector. EPA is committed to expeditiously proposing GHG emission guidelines for these units, as part of a comprehensive approach to the regulation of climate, toxic and air pollution from combustion turbines.

Strengthening Mercury and Air Toxics Standards

EPA is strengthening and updating the Mercury and Air Toxics Standards (MATS) for coal-fired power plants, achieving important hazardous air pollutant (HAP) emissions reductions and ensuring that the standards reflect the latest advancement in pollution control technologies. This final rule under the Clean Air Act is the most significant update since MATS was first issued in February 2012, building on highly successful and cost-effective protections.

EPA projects the final rule will reduce emissions of mercury and non-mercury metal HAPs, such as nickel, arsenic, and lead. Controlling these emissions from power plants improves public health for all Americans by reducing the risk of fatal heart attacks, cancer, developmental delays in children, and also reduces adverse environmental impacts. The final rule will also result in substantial co-benefits, including reductions in emissions of fine particulate matter (“soot”), sulfur dioxide, nitrogen oxides, and carbon dioxide nationwide. These public health improvements are especially important for children and communities with environmental justice concerns and others who regularly consume fish that accumulate high levels of pollutants from power plants.  

The final rule reduces the mercury emissions limit by 70 percent for lignite-fired units and reduces the emissions limit that controls for toxic metals by 67 percent for all coal plants—while also requiring the use of continuous emission monitoring systems to provide real-time, accurate data to regulators, facility operators, and the public to ensure that plants are meeting these lower limits and that communities are protected year-round from pollution exposure.

EPA projects that the final MATS limits will result in the following emissions reductions in the year 2028: 

• 1,000 pounds of mercury
• At least 7 tons of non-mercury HAP metals
• 770 tons of fine particulate matter (PM2.5)
• 280 tons of nitrogen oxides (NOx)
• 65,000 tons of carbon dioxide (CO2)

EPA’s final rule projects $300 million in health benefits and $130 million in climate benefits over the 10-year period from 2028-2037. Reductions in non-mercury HAP metal emissions are expected to reduce exposure to carcinogens such as nickel, arsenic, and hexavalent chromium, for residents living in the vicinity of these facilities.

Stronger Limits on Water Pollution from Power Plants

EPA is strengthening wastewater discharge standards that apply to coal-fired power plants, finalizing a rule that follows the latest science and applies EPA’s longstanding authority under the Clean Water Act to reduce discharges of toxic metals and other pollutants from these power plants into lakes, streams, and other waterbodies. When implemented, this action will annually prevent more than 660 million pounds of pollution per year from being discharged to our nation’s waters—protecting freshwater resources that provide sources of drinking water for communities, support economic development, enhance outdoor recreation, and sustain vibrant ecosystems.

Power plants that burn coal to create electricity use large volumes of water. When this water is returned to lakes, streams, and other waterbodies it can carry pollutants, including mercury, arsenic, selenium, nickel, bromide, chloride, and iodide, and nutrient pollution. Exposure to these pollutants can harm people and ecosystems by contaminating drinking water sources, recreational waters, and aquatic life.

EPA’s final rule establishes technology-based discharge standards—known as Effluent Limitation Guidelines (ELGs)—that will apply to four types of wastewater:

• Flue gas desulfurization wastewater
• Bottom ash transport water
• Combustion residual leachate
• “Legacy wastewater” that is stored in surface impoundments (for example, coal ash ponds)

The agency’s final rule includes implementation flexibilities for power plants. For example, the final rule creates a new compliance path for electricity generating units that permanently stop burning coal by 2034. These units will be able to continue meeting existing requirements instead of the requirements contained in this final regulation. In a separate action finalized last year, EPA updated but maintained an existing provision allowing units to comply with less stringent standards if they will permanently stop burning coal by 2028.

Following rigorous analysis, EPA has determined that this final rule will have minimal effects on electricity prices. EPA’s analysis shows that the final rule will provide billions of dollars in health and environmental benefits each year. These water quality, health, and environmental improvements will benefit environmental justice communities that are disproportionately affected by pollution from coal-fired power plants.

Latest Action to Protect Communities from Coal Ash Contamination

Under the Resource Conservation and Recovery Act, EPA is finalizing a rule to protect communities and hold polluters accountable for controlling and cleaning up the contamination created by the disposal of coal combustion residuals (CCR or coal ash), which can cause serious public health risks. The agency is finalizing regulations that require the safe management of coal ash at inactive surface impoundments at inactive power plants and historical coal ash disposal areas.

Coal ash is a byproduct of burning coal in power plants that, without proper management, can pollute waterways, groundwater, drinking water, and the air. Coal ash contains contaminants like mercury, cadmium, chromium, and arsenic which are associated with cancer and various other serious health effects. EPA’s final rule expands protections for the communities and ecosystems near active and inactive coal burning power plants, ensuring that groundwater contamination, surface water contamination, fugitive dust, floods and impoundment overflows, and threats to wildlife are all addressed.

Inactive coal ash surface impoundments at inactive facilities, referred to as “legacy CCR surface impoundments,” are more likely to be unlined and unmonitored, making them more prone to leaks and structural problems than units at facilities that are currently in service. To address these concerns, EPA established safeguards for legacy coal ash surface impoundments that largely mirror those for inactive impoundments at active facilities, including requiring the proper closure of the impoundments and remediating coal ash contamination in groundwater. EPA analysis shows the final rule will reduce existing disproportionate and adverse effects on communities with environmental justice concerns.

In addition, through implementation of the 2015 CCR rule, EPA found “historic” disposal units that are leaking and contaminating groundwater at currently regulated power plants, but which were exempt under the original 2015 regulations. These are areas where coal ash was placed directly on the land, such as coal ash in surface impoundments and landfills that closed prior to the effective date of the 2015 CCR Rule and inactive CCR landfills. This final rule extends a subset of EPA’s existing CCR requirements to these historic disposal units that will ensure any contamination from these areas is remediated, and will prevent further contamination. These requirements will apply to all active CCR facilities and inactive facilities with legacy CCR surface impoundments.

EPA does not expect this rule to affect the current operations of power plants, and therefore anticipates no impacts to electricity generation or grid reliability. This rule reflects the Administration’s commitment to reduce pollution from the power sector while providing long-term regulatory certainty and operational flexibility.

Water pollution is the release of substances into subsurface groundwater or into lakes, streams, rivers, estuaries, and oceans to the point where the substances interfere with beneficial use of the water or with the natural functioning of ecosystems.

Some of the primary sources water pollution are: domestic sewage, solid waste, toxic waste, sediment, thermal pollution, petroleum (oil) pollution.

Water pollution can result in the degradation of aquatic ecosystems, spread of gastrointestinal diseases and parasitic infections, eutrophication, and ocean acidification.

Around 70% of industrial waste is dumped to water. 80% of the water pollution is caused due to domestic sewage. More than 6 billion pounds of garbage, mainly plastic end up in the oceans every year. 15 million children under the age of five years die every year from diseases caused by drinking contaminated water. The Ganges river in India is considered the most polluted river in the world.
