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.

Title: Water Pollution – A Growing Threat to Ecosystems and Human Well-being

Introduction :

Water pollution is a grave environmental issue that arises from the contamination of water bodies by harmful substances. It poses a significant threat to aquatic ecosystems and human health. This essay explores the causes and consequences of water pollution, as well as the measures required to address and prevent it.

Causes of Water Pollution

Water pollution can be attributed to various human activities and natural factors. Industrial discharge, improper waste disposal, agricultural runoff, oil spills, sewage, and chemical pollutants are among the leading causes. Rapid urbanization, population growth, and inadequate infrastructure for waste management contribute to the problem. Additionally, natural phenomena like sedimentation and erosion can exacerbate water pollution.

Consequences of Water Pollution

Water pollution has far-reaching ecological and human health implications. Contaminated water disrupts aquatic ecosystems, leading to the decline of fish and other marine species. It affects biodiversity, disrupts food chains, and damages habitats. Moreover, polluted water sources pose significant health risks to humans. Consuming or coming into contact with contaminated water can lead to waterborne diseases, gastrointestinal issues, skin problems, and even long-term health impacts.

Prevention and Remediation

Addressing water pollution requires a multi-faceted approach. Stricter regulations and enforcement regarding industrial discharge and waste management are essential. Promoting sustainable agricultural practices, such as reducing the use of chemical fertilizers and implementing proper irrigation techniques, can minimize agricultural runoff. Developing and implementing advanced wastewater treatment technologies is crucial to ensure that domestic and industrial effluents are properly treated before being discharged into water bodies.

Individual and Collective Responsibility:

Preventing water pollution is a shared responsibility. Individuals can contribute by practicing responsible waste disposal, conserving water, and avoiding the use of harmful chemicals. Public awareness campaigns and education programs play a vital role in promoting responsible behavior and fostering a culture of environmental stewardship.

Conclusion :

Water pollution is a critical environmental issue that jeopardizes the health of ecosystems and humans. It demands collective action and responsible behavior. By addressing the root causes of water pollution, implementing effective regulations, and promoting individual and collective responsibility, we can safeguard water resources and ensure a sustainable future for generations to come.

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

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

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

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

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

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

Solutions and Mitigation Strategies

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

a. Regulatory Measures

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

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

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

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

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

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

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

What is water pollution?

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

What human activities cause water pollution?

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

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

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

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

Types and sources of water pollutants

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Water Pollution Essay – Sample 2 (350+ Words)

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

What is Water Pollution?

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

Effects of Water Pollution on Human Health

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

Minamata Incident – A Severe Case of Water Pollution

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

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

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

FAQ’s on Water Pollution

Essay on Water Pollution for Students and Children

500+ words essay on water pollution.

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

Water and Water Cycle

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

What is Water Pollution?

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

Sources of Water Pollution

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

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

Effects of Pollution of Water

The effects of Water Pollution are:

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

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

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

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

Prevention of Water Pollution

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

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

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

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

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

Essay on Water Pollution in 200 Words

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

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

Contaminants 

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

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

Solution 

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

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

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

Essay on Water Pollution in 500 Words

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

Reasons for Water Pollution

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

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

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

Methods of Water Pollution Management

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

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

Real-Life Encounter

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

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

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

Water Pollution: Causes, Effects and Possible Solutions Expository Essay

• To find inspiration for your paper and overcome writer’s block
• As a source of information (ensure proper referencing)
• As a template for you assignment

Introduction

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

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

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

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

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

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

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

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

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

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

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

Essay on Water Pollution : Causes, Effects & Solutions

February 2, 2021 by Study Mentor Leave a Comment

Water is one of the most important factors essential for sustaining life. Every organism, no matter how big or small, requires water to live.

You must’ve noticed that water quality has undergone a sea change over the years. The water has gotten harder and harder.

The color of water in rivers and lakes has significantly changed. The crystal clear surface on water bodies was a thing of the past and we no longer get to see a picturesque image of a clean and perfect water body anymore.

The tap water we receive can no longer be used for drinking, and we are forced to buy separate drinking water, install water purifying devices in our homes.

Have you wondered why we are forced to go in for such applications at our homes. There is no answer for water scarcity in big cities today and people are forced to live with the bitter truth.

Table of Contents

What is water pollution?

Water pollution is nothing but contamination of water bodies with chemicals, toxins and effluents let out from industrial establishments and factories.

These toxins contain harmful concentrations of lead, Sulphur, heavy metals and detergents in them.

Not just that, water bodies are mixed with sewage water and one can imagine the extent of dirt and filth that is contained in the waters of river bodies, thus making them highly polluted.

Pollution is tainting or forcefully mixing harmful and toxic substances into environment. These substances that endanger the consistency and integrity of the environment are called Pollutants.

Pollutants have been ever rampant since man entered the industrial ages.

The environment has been enduring the abuse we afflicted on it since ages. Industries, factories, etc. contribute to pollution on a large scale.

The daily activities that we perform, also pollute the earth due to inefficiency of the methods we use. Alarming quantities of pollutants are being produced and released.

Causes of water pollution

Speaking about water, most of the industries and factories have leftover chemical effluents. They release these residual products into primary water sources like rivers streams, lakes, fresh water tanks etc.

These residues may be a mixture of a myriad of chemically toxic substances.

The microbes present in the natural sources of water have the ability to purify the water to some extent. But the problem arises when we dump more Pollutants before the current batch of water is purified.

Purified, in this context, means oxidizing the water.

Microbes present in water have the natural ability to oxidize it. But constant human intended interference has almost nullified that ability.

In short, pollutants just overtake the good microbial activity and instead cause damage to water sources by inducing them  with filth and dirt.

The activities of the microbes in cleaning up the water reduce to a low minimum or may not take place at all. Waste water from domestic sources is also often dumped into rivers. This pollutes the entire source.

Effects of water pollution

Water pollution affects us on a daily basis. The cases of water borne disease are on the rise. Since water is one of the building blocks of life, we have but no choice to consume the same water in adequacy.

The dangers of polluted water increases when people unknowingly use polluted water for daily purposes.

This mostly occurs in rural areas, where rivers are a prime source of water.

Factories set up near river bodies may be releasing effluents and people downstream maybe using the same water for drinking purposes and for other daily activities.

It is common knowledge that 70 percent of the earth is covered by water. But not all of this water can be used for drinking and household purposes.

Only a small percentage is fresh water, and most of the other share in the percentage finds itself frozen at the Poles.

The advent of pollution has further reduced the potable water resources. Water available today is way more polluted than it was ages ago.

Our quality of life is greatly affected by this. Use of polluted water causes diseases and ailments. It can be directly linked to the receding length of our lifespan.

Solutions for water pollution

Humans have realized that they have greatly affected the environment in a bad way. Everywhere, efforts are being made to conserve water.

Water treatment plants are setup everywhere. Every waste disposal station has a water treatment department, so that all the chemical and other harmful substances can be removed from water before it is let into the main source.

This has been pivotal in controlling pollution of water. Rules and regulations have been made stringent for factories and industries, regarding their effluent emission, both through the air and through water.

Domestic waste disposal techniques have been improved and proper steps taken in the right direction.

It is entirely up to us, what we decide to do, with our water sources. Global warming is becoming an ever gaping issue and a worldwide concern. There’s always fear of the rains being more infrequent and unseasonal.

What on earth do we do without adequate water. The hardships we’d have to face to obtain enough water for sustaining looks so terrible if we were to quest for a suitable answer.

The everyday tasks that we do would become incredibly difficult. We need to take measures ourselves, to save water and keep it from being polluted.

We must start conserving water in our homes. Only then will the next generation have even the slightest hope for a well-rounded future.

Water pollution is actually a two-fold issue raising global concerns today.

The first issue, the most common one as we know is of the contamination of water by toxins and measures to reduce the contamination and improve the quality of water.

The second one is more serious and pertains to the availability of potable water on earth after some years, putting a question mark on the survival of life on earth itself.

We talk about beautifying our lakes, restoring the cleanliness of our water bodies, removing their contaminants and making them toxic free.

Yes, this is definitely required at the moment and there have been measures taken in the right direction to make our rivers clean and clear.

Specific installations of dust collector and dirt remover equipment’s in river basins have been employed to collect waste material from river surfaces.

This is primarily to remove hard traces of waste or what we can call as visible wastes. This also takes removes unnecessary growth of phytoplankton in rivers, thus letting the river waters breathe at ease.

Regarding toxin removal from river waters, purification using reverse osmosis methods, chemical filtration methods and other treatments using distillation methods are employed to make them free from chemical residues.

Much other advancement have been achieved and successfully employed in the river basins of our country to restore the natural beauty of lakes and rivers.

The best example of river water cleaning in our country is the cleanliness drive carried out at river Ganga in the holy city of Varanasi.

The government of India took it up as a big challenge to clean the river waters at the region and was successful in achieving its mission.

It is only with citizen co-operation and participation that any reformative measures taken by the governments will prove fruitful and worthy of action.

We blame successive governments for not cleaning up our river beds, for not providing us clean drinking water, for not beautifying our lakes etc.

In the melee, we forget our own responsibilities of acting with care and concern.

If we visit rural areas and spot women washing their clothes, utensils and cattle in river waters, it is our duty to educate them and spread awareness about their wrong acts.

We ought to tell them that they aren’t supposed to pollute the river water.

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.

Effects of Water Pollution on Human Health

Introduction, causes of water pollution, how to mitigate water pollution, works cited.

Water pollution is a major global issue in both developing and developed countries. In 2020, over half of the U.S. lakes and rivers breached the environmental standards, and American drinking water comes from 4-28% of sources that infringe the health standards (Sharma et al. 5). Annually, over 16 million US citizens suffer gastrointestinal diseases due to drinking contaminated water. The U.S. government spends over $4.8 trillion, 0.8% of the total GDP, cleaning up surface water pollution and ensuring safe drinking water for all its citizens (Keiser and Shapiro 52). However, each US national spends an average of $60 annually on bottled water (Keiser and Shapiro 52). This study will evaluate the main causes of water pollution, the effects on humans health, and how to mitigate them.

One of the main causes of water pollution is sewage. Untreated or partially treated sewage disposal into water sources is the most common form of water contamination. Although there have been efforts to use more biological and technological methods to treat sewage, water pollution is still a prevalent issue. According to the United States Environmental Protection Agency, the recommended sewage effluent should have biochemical oxygen demand of 20 p.p.m or lower and suspended solids of less than 30 p.p.m (Klein 112). However, most companies and other sewage sources cannot meet these thresholds. For instance, coal mining areas have been unable to meet these standards due to defects such as fractures in their pipes, tanks, or sewers, which cause mass water contamination.

The other cause of water contamination is discharge from trade wastes. People in a densely populated region are likely to excrete too much trade waste, and if not well disposed of, it may affect water sources such as rivers and lakes (Klein 114). In densely populated areas such as South East Michigan, some rivers famous for fishing, such as the Rogue River, are now dead and cannot support vegetable or animal life. If the water sources are not large enough to dilute the effluent during heavy storm overflow, all the waste transferred into the rivers or lakes may become a major pollutant.

Industries contribute significantly to water pollution. They discharge different pollutants into the environment either directly or indirectly. The manufacturiong industry, which ues too much chemical, is an essential contributor to water contaminaton (Mitiku 96). These activities lead to the generation of waste with varying organic and inorganic components, which are carcinogenic, toxic, and non-biodegradable. When this waste gets into the water sources, it contaminates them and makes the water unhealthy for human consumption and sometimes unable to support aquatic life.

While using manure and other agricultural products helps boost crop productivity, it still has detrimental effects on water sources. The application of manure and fertilizers pollute both surface and underground water (Mitiku 95). Most fertilizers nowadays are manufactured using high levels of metal content to boost the nutrients in the crops; however, this metal concentration is dangerous because it is often swept off into the nearest water sources or reserves. Other agricultural pollutants include highly toxic pesticides and the water runoff from farming fields into streams.

Oil spills are another factor leading to water pollution, especially in the oceans. When big spills hit the headlines, it is always an indication that massive water pollution has happened in the seas or oceans. In 2021, there were six tanker oil spills, with more than 700 metric tons of oil being spilled in the sea (Denchak). However, these are not the only type of oil pollution that occurs as tons of oil drip daily from millions of cars. This oil either spills into the ground or is carried by running water during rainy seasons into the rivers, lakes, or other water reservoirs, polluting the water. More than a million tons of oil in other marine environments comes from land-based sources such as factories, cities, and farms. Additionally, seeps from under the sea also release oil naturally, which shows that water pollution is not only from man-made forms.

Water pollution has been associated with various health problems such as Diarrhea, Cholera, Typhoid, Hepatitis A, and Dysentery. Various microbial chemicals can pollute water and make it unhealthy for human consumption. These may include pathogens, human care products and nitrates. 10% of the world’s population consumes food that is grown in contaminated areas (Mitiku 95). Poor people are more exposed to health problems that are related to water contamination.

Polluted water can lead to bacterial diseases. Drinking untreated water is the main cause of diarrhea. Headache, abdominal pain, nausea, and fever are diarrhea symptoms and are commonly spread by Campylobacter jejuni bacteria. Another bacterial disease caused by polluted water is Cholera. Cholera is caused by a bacteria called Vibrio Cholerae, which releases toxins in the digestive tract. According to the World Health Organization, there are 1.3 to 4 million cases of Cholera every year and up to 143,000 deaths related to the disease (Denchak). The Shigella bacteria cause shigellosis by damaging the intestinal lining. This shows that polluted water may have devastating health effects, especially in developing countries.

Polluted waste can as well lead to viral diseases. For instance, contaminated water can cause Hepatitis, a viral disease. Its main symptoms are discomfort, loss of appetite, fever, and fatigue, and if not treated for a long time, it can lead to death (Haseena et al. 17). There are vaccines for Hepatitis, and adopting good hygienic standards can eliminate the disease. Another viral disease is Encephalitis, caused by mosquito bites and contaminated water where they lay their eggs (Haseena et al. 17). Although the disease does not show any symptoms, it may cause paralysis or severe coma. Poliomyelitis is caused by a virus known as poliomyelitis, and although a vaccine is available, this disease is dangerous when it attacks a young child or disabled person.

Some parasitic diseases may originate from polluted water. For instance, cryptosporidiosis is a disease that affects people worldwide and is caused by a parasite known as cryptosporidium parvum. This disease causes diarrhea and is resistant to disinfection, making it a killer disease. According to the World Health Organization, approximately 4 million people are infected with diarrhea annually, while 2 million people die from diarrhea-related illnesses (Haseena et al. 18). This shows that diseases related to water pollution are prevalent healthcare problems, especially in developing countries.

One of the methods of avoiding water contamination is monitoring water distribution systems. Sometimes drinking water can be pumped from a safe environment with no bacteria detected in it, and it is infected when it reaches the consumer. This shows that the water distribution system is where the water gets contaminated in most cases. The water distribution systems should be flushed and disinfected after a specific time to remove the sediments and debris in the pipes (Klein 134). Additionally, conducting random laboratory analysis can help ascertain that the water for human consumption is safe.

Another method of treating water for human consumption is the herbal disinfection of water. This method is used mostly in rural areas where modern treatment of water is not affordable. For instance, alcoholic extract can be used by communities who use well water while those close to lakes can use aqueous (Klein 128). Neem ( Azadirachta indica ), tulsi ( Ocimum sanctum ), and amla are herbs that are used in treating microbial infections and they do not have any side effects; they can be used in the treatment of water.

Government policy can be used to reduce water pollution. For instance, US EPA has created various regulations which direct how companies and markets should dispose of their waste to avoid contaminating the water around them (Klein 127). According to the laws, water pollution should be treated from the source if feasible. The government should come up with more strict rules and enforcement agencies to ensure that factories do not pollute rivers. US EPA has regulated the amount of sediment that should be in company waste before it is disposed of and the chemical composition. However, they should be stricter in implementing the policies to ensure that the companies do not break them.

Harmful wastes like chemicals from industries, household wastes, or medical wastes deteriorate the quality of water, resulting in the death of aquatic life.

2. Harmful to Humans

Water is a significant source of survival for humans. However, harmful pollutants lower the quality of drinking water. They cause diarrhea, dysentery, cholera, hepatitis A, polio, and typhoid. In some cases, drinking polluted water may even cause the death of individuals.

3. Damage to Natural Habitats

It can also negatively impact natural habitats like wetlands and estuaries. These are vital to the health of many species. Pollution can damage these habitats and make them less able to support plant and animal life.

4. Increased Greenhouse Gas Emissions

It also contributes to climate change, as the decomposition of organic matter in polluted water can produce greenhouse gases, such as carbon dioxide and methane. It can contribute to global warming and the overall warming of the planet.

5. Affects Economy

Many industries, like tourism and agriculture, rely on clean water. Polluted water can have huge consequences on these industries. Each year $260 billion is lost due to the unavailability of basic water and sanitation.

Tips to Reduce

There are many proven ways to reduce water pollution. Choosing a mode of life that is less materialistic and ancient can be the starting step to reducing water pollution. Here are some more ways to reduce.

1. Conserve Water

One of the highly effective ways to reduce is to use water efficiently. Fixing leaks, using drought-resistant plants in landscaping, and taking shorter showers, can all help to reduce water usage. Thus, efficient usage of water results in a lower amount of water wastage.

2.  Properly Dispose of Household Chemicals

Many household products, such as cleaning agents and pesticides, contain harmful chemicals that can pollute water. It’s essential to follow the instructions on the labels of these products and dispose of them in a way that will stop them from entering the water supply. It reduces the risk of water pollution.

3. Support Environment-friendly Farming Practices

Agricultural activities, such as using fertilizers and pesticides, can contribute to water pollution. Supporting farmers who use sustainable farming practices help in reducing the supply of pollutants in the water.

4. Reduce Plastic Usage

Plastic is a significant contributor to water pollution, as it can break down into smaller pieces and enter the water supply. Reducing your use of plastic products, such as single-use plastic bottles and bags, can help reduce the amount of plastic pollution in the water.

5. Support Water Treatment Facilities

Properly functioning water treatment facilities are essential for reducing water pollution. Supporting efforts to upgrade and maintain these facilities can ensure that the water supply is clean and safe for everyone. In conclusion, it is a serious issue affecting the health of humans, animals, and the environment.

By taking steps to prevent and reduce water pollution, we can protect the quality of our water and ensure a healthy and sustainable future for us and the coming generation.

Essay on Water Pollution: Types, Causes, Effects & Prevention

March 10, 2021 by Sandeep

Water Pollution Essay: When water gets contaminated by pollutants making it unhealthy and unfit to consume, we call it water pollution. The pollution of water bodies like oceans, rivers, lakes, and underground sources has drastically affected life forms. Domestic and industrial wastes, pesticides and effluents mainly pollute water.

Essay on Water Pollution 500 Words in English

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

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

Types of Water Pollution

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

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

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

Causes of Water Pollution

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

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

Prevention of Water Pollution

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

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

The world's plastic pollution crisis, explained

Much of the planet is swimming in discarded plastic, which is harming animal and possibly human health. Can it be cleaned up?

Plastic pollution has become one of the most pressing environmental issues , as rapidly increasing production of disposable plastic products overwhelms the world’s ability to deal with them. Plastic pollution is most visible in developing Asian and African nations, where garbage collection systems are often inefficient or nonexistent. But the developed world, especially in countries with low recycling rates , also has trouble properly collecting discarded plastics. Plastic trash has become so ubiquitous it has prompted efforts to write a global treaty negotiated by the United Nations.

Why was plastic invented?

Plastics made from fossil fuels are just over a century old. Production and development of thousands of new plastic products accelerated after World War II, so transforming the modern age that life without plastics would be unrecognizable today. In plastic, inventors found a light, durable material that can be used in everything from transportation to medicine.  

Plastics revolutionized medicine with life-saving devices, made space travel possible, lightened cars and jets—saving fuel and pollution—and saved lives with helmets, incubators, and equipment for clean drinking water.

The conveniences plastics offer, however, led to a throw-away culture that reveals the material’s dark side: today, single-use plastics account for 40 percent of the plastic produced every year. Many of these products, such as plastic bags and food wrappers, have a lifespan of mere minutes to hours, yet they may persist in the environment for hundreds of years.

Plastics by the numbers

Some key facts:

• Half of all plastics ever manufactured have been made in the last 20 years.
• Production increased exponentially, from 2.3 million tons in 1950 to 448 million tons by 2015. Production is expected to double by 2050.
• Every year, about eight million tons of plastic waste escapes into the oceans from coastal nations. That’s the equivalent of setting five garbage bags full of trash on every foot of coastline around the world.
• Plastics often contain additives making them stronger, more flexible, and durable. But many of these additives can extend the life of products if they become litter, with some estimates ranging to at least 400 years to break down.

How plastics move around the world

Most of the plastic trash in the oceans, Earth’s last sink, flows from land. Trash is also carried to sea by major rivers , which act as conveyor belts, picking up more and more trash as they move downstream. Once at sea, much of the plastic trash remains in coastal waters. But once caught up in ocean currents, it can be transported around the world.

On Henderson Island , an uninhabited atoll in the Pitcairn Group isolated halfway between Chile and New Zealand, scientists found plastic items from Russia, the United States, Europe, South America, Japan, and China. They were carried to the South Pacific by the South Pacific gyre, a circular ocean current.

Microplastics—a new health threat

Once at sea, sunlight, wind, and wave action break down plastic waste into small particles, often less than one-fifth of an inch across. These so-called microplastics are spread throughout the water column and have been found in every corner of the globe, from Mount Everest, the highest peak, to the Mariana Trench , the deepest trough.

The Haunting Art of Plastic Pollution

Microplastics are breaking down further into smaller and smaller pieces. Plastic microfibers, meanwhile, have been found in municipal drinking water systems and drifting through the air.

It's no surprise then that scientists have found microplastics in people. The tiny particles are in our blood, lungs, and even in feces . Exactly how much microplastics might be harming human health is a question scientists are urgently trying to answer. ( Learn more. )

Harm to wildlife

Millions of animals are killed by plastics every year, from birds to fish to other marine organisms. Nearly 700 species, including endangered ones, are known to have been affected by plastics. Nearly every species of seabird eats plastics.

Most of the deaths to animals are caused by entanglement or starvation. Seals, whales , turtles, and other animals are strangled by abandoned fishing gear or discarded six-pack rings . Microplastics have been found   in more than 100 aquatic species, including fish, shrimp, and mussels destined for our dinner plates. In many cases, these tiny bits pass through the digestive system and are expelled without consequence. But plastics have also been found to have blocked digestive tracts or pierced organs, causing death. Stomachs so packed with plastics reduce the urge to eat, causing starvation.

Plastics have been consumed by land-based animals, including elephants, hyenas, zebras, tigers, camels, cattle, and other large mammals, in some cases causing death .

Tests have also confirmed liver and cell damage and disruptions to reproductive systems,   prompting some species, such as oysters, to produce fewer eggs. New research shows that larval fish are eating nanofibers in the first days of life, raising new questions about the effects of plastics on fish populations.

Stopping plastic pollution

Once in the ocean, it is difficult—if not impossible—to retrieve plastic waste. Mechanical systems, such as Mr. Trash Wheel , a litter interceptor in Maryland’s Baltimore Harbor, can be effective at picking up large pieces of plastic, such as foam cups and food containers, from inland waters. But once plastics break down into microplastics and drift throughout the water column in the open ocean, they are virtually impossible to recover.

The solution is to prevent plastic waste from entering rivers and seas in the first place, many scientists and conservationists—including the National Geographic Society —say. This could be accomplished with improved waste management systems and recycling , better product design that takes into account the short life of disposable packaging, and a reduction in manufacturing of unnecessary single-use plastics.

FACT SHEET: Biden- ⁠ Harris Administration Takes Critical Action to Protect Communities from PFAS Pollution in Drinking   Water

EPA Announces First-Ever National Standard to Address PFAS in Drinking Water, Delivers an Additional $1 Billion through President Biden’s Investing in America Agenda to Combat PFAS Pollution

President Biden believes every community has the right to clean, safe drinking water, free of pollutants that harm people’s health and wellbeing. That is why the President launched a comprehensive action plan and provided billions in funding to protect communities from toxic “forever chemicals” that are linked to a range of severe health problems, including cancers, liver and heart damage, and developmental impacts in children. Found in drinking water, soil, air, and our food supply, per- and polyfluoroalkyl substances (PFAS) persist in the environment for long periods of time, posing a serious health threat across rural, suburban, and urban areas.

Today the Environmental Protection Agency (EPA) is announcing the first-ever national legally enforceable drinking water standard for PFAS , which will protect 100 million people from PFAS exposure , prevent tens of thousands of serious illnesses, and save lives. This action complements the Biden-Harris Administration’s commitment to combatting PFAS pollution and delivering clean water.

President Biden has secured historic levels of funding to meet this new standard. Today, the Biden-Harris Administration is also announcing an additional $1 billion through President Biden’s Investing in America agenda to help every state and territory fund PFAS detection and treatment systems to meet the new standard . This funding is part of the $9 billion in dedicated funding through the President’s Bipartisan Infrastructure Law to address PFAS and other emerging contaminants in drinking water – the largest-ever investment in tackling PFAS pollution. An additional $12 billion in funding from the Bipartisan Infrastructure Law supports general drinking water investments, including PFAS treatment. The investments are part of the  Justice40 Initiative , which aims to ensure that 40 percent of the overall benefits of certain federal investments flow to disadvantaged communities.

These actions will help tackle PFAS pollution that has devastated communities like Oakdale, outside of St. Paul, Minnesota, where decades of PFAS-containing waste dumped by a chemical plant has contaminated the community’s drinking water. In this area, cancer was found to be a far more likely cause of death in children than in neighboring areas. The funding announced today will build on funding from the President’s Bipartisan Infrastructure Law that is already helping communities address PFAS contamination, including a $33 million award for Tucson, Arizona to treat its PFAS-contaminated drinking water wells.

This funding also builds on President Biden’s action plan  to address PFAS pollution , safeguard public health, and advance environmental justice – all while advancing the Biden Cancer Moonshot goal of cutting the cancer death rate by at least half by 2047 and preventing cancer before it starts by protecting communities from known risks associated with PFAS exposure.

As the first-ever Safe Drinking Water Act standard for PFAS – and the first for any new contaminants since 1996 – this rule sets health safeguards and will require public water systems to monitor and reduce the levels of PFAS in our nation’s drinking water, and notify the public of any exceedances of those levels. The rule sets drinking water limits for five individual PFAS, including the most frequently found PFOA and PFOS. Because PFAS can often be found together in mixtures, EPA is also setting a limit for any combination of four PFAS, including GenX Chemicals. This standard will reduce PFAS exposure in our drinking water to the lowest levels that are feasible for effective nationwide implementation.

Today’s announcements advance President Biden’s broader commitment to deliver clean water for every American. The President’s Bipartisan Infrastructure Law invests over $50 billion to upgrade water infrastructure – the largest investment in clean water in American history. This includes a historic $15 billion to replace toxic lead pipes and protect children from brain damage, as part of President Biden’s goal of replacing every lead pipe in the country within a decade.

Recent Federal Actions to Protect Communities from PFAS

Under President Biden’s leadership, nearly two dozen federal agencies and offices have made systematic and substantive progress to safeguard public health and protect the environment from PFAS in drinking water and beyond. This work is coordinated by the White House Council on Environmental Quality, which leads the Interagency Policy Committee on PFAS. Other new actions the Biden-Harris Administration has advanced to combat PFAS pollution over the past year include:

Protecting Firefighters from PFAS : The Biden-Harris Administration is committed to protecting firefighters from the harmful effects of PFAS contained in fire suppressing agents and firefighter gear. The Department of Defense is offering PFAS blood tests to military firefighters. The Federal Emergency Management Agency’s U.S. Fire Administration is working to reduce PFAS exposure and promoting access to early cancer screenings and participation in the National Firefighter Registry for Cancer led by the National Institute for Occupational Safety and Health as part of President Biden’s mission to end cancer as we know it.

Reducing PFAS in Fire Suppressants: The Department of Defense (DoD) qualified three fluorine-free foams to replace fluorinated Aqueous Film Forming Foam for shore-based firefighting activities at military installations, which the Federal Aviation Administration (FAA) has authorized for civilian airports. The FAA is assisting airports to transition to these new foams , and funding foam testing systems for airports that prevent environmental discharge. These changes will reduce the release of PFAS in the environment and protect the health of firefighters and local communities.

Supporting Healthcare Providers: The Agency for Toxic Substances and Disease Registry at the Centers for Disease Control and Prevention recently released the PFAS: Information for Clinicians resource guide. This information gives clinicians up-to-date resources and information they need to help patients with questions and concerns about PFAS exposure and health effects.

Phasing Out PFAS in Food Packaging: The Food and Drug Administration (FDA) announced the completion of the voluntary market phase-out of PFAS used on paper and paperboard food packaging, eliminating the primary source of dietary exposure to PFAS . FDA can now also test for 30 PFAS in a variety of foods to further protect people from dietary PFAS exposure.

Testing for and Cleaning Up PFAS Pollution: EPA continues to take key actions to address PFAS . For example, EPA is gathering data on 29 PFAS in the nation’s drinking water systems has collaborated with DoD to develop a method to test for 40 PFAS in various media including biosolids, groundwater, and fish tissue. EPA also updated its interim PFAS disposal and destruction guidance and has released a new method to test for 30 volatile fluorine-containing compounds in air including potential products of incomplete combustion of PFAS. DoD recently identified 40 installations where interim cleanup actions to prevent further PFAS migration are underway or will start in FY2024. These actions will address PFAS in groundwater to protect public health and the environment.  

Reducing PFAS in Federal Procurement: EPA and the U.S. General Services Administration announced this week that custodial contracts for federal buildings will now only use cleaning products certified to ecolabels such as EPA’s Safer Choice and certain Green Seal standards, thereby avoiding products that contain intentionally added PFAS. This shift will protect the environment, federal custodial workers, other federal employees, and those visiting government buildings.

Water is bursting from another abandoned West Texas oil well, continuing a troubling trend

Pecos County rancher Schuyler Wight says the Railroad Commission continues to plug wells. But each time they do, another one starts flowing.

Subscribe to The Y’all — a weekly dispatch about the people, places and policies defining Texas, produced by Texas Tribune journalists living in communities across the state.

In recent years, Schuyler Wight has noticed a growing number of abandoned oil wells coming back to life, gurgling fluids on the surface of his West Texas ranch. Last week he found the biggest one yet.

Gassy water was gushing from the ground and down a quarter mile of roadway before it drained into a pasture on a remote corner of his land.

“It’s by far flowing more than any other,” Wight said. “It’s getting worse, there's no question about that.”

It’s the latest in a string of mysterious water features in the arid Permian Basin, the nation’s top producing oil field, that regulators have been unable to explain.

Last year, an eruption of salty water swamped several acres on Wight’s cousin’s ranch, triggering a multi-million-dollar cleanup. In 2022, a geyser shot up from a well in Crane County, then another on the Antina Cattle Ranch. Nearby, a large pond of gassy groundwater has become a permanent feature called Boehmer Lake.

Texas’ oilfield regulator, the Texas Railroad Commission, has yet to offer an explanation for what is driving so much water to the surface. After the massive cleanup effort in January, an agency press release said it was “continuing to investigate” the cause. The Railroad Commission did not immediately respond to a query.

“nobody really knows what you’re supposed to do”: leaking, exploding abandoned wells wreak havoc in west texas.

Feb. 29, 2024

Wight, a fourth-generation West Texas rancher, has watched this problem grow for years. He said the commission has plugged about 10 old wells leaking onto the surface of his property. But each time they do, another one starts flowing.

“Words can’t describe how far behind they are and how bad they are doing at this,” he said. “There’s going to be more of this, not just in Pecos County. You’re going to see it all over the place.”

There’s nothing uncommon about a leaky old well. Many in West Texas were drilled during World War II and 80 years underground can do major damage to steel and concrete casing. Many of those wells were also flooded with water to squeeze out the last drops of oil.

The mystery now in the Permian Basin is what is pushing large volumes of that water up to the surface.

“There’s a source of pressure there and it’s shallow,” said Hawk Dunlap, an oilfield firefighter who lives in Crane County and surveyed the recent blowout for Wight last week. “It’s not clear what the source is.”

Dunlap has worked oilfield emergencies in 102 countries, he said. He’s seen water dribbling up from old oil wells before, but never anything close to the quantity he’s seen in West Texas.

It’s strange, he said, because local ranchers need pumps to draw from their water wells. But every so often, it comes out of an oil well by itself.

Dunlap suspects it may be related to the injection of fracking wastewater. West Texas oil producers pump millions of gallons of so-called produced water, laced with chemical lubricants and numerous hazardous compounds such as arsenic, bromide, strontium, mercury, barium, and organic compounds, particularly benzene, toluene, ethylbenzene and xylenes, underground every day for disposal, often into old oil and gas wells.

In theory, the produced water will remain in those wells and rock formations in perpetuity. But the geological science is imprecise, and if the water broke out its confines, it could affect pressure in other pockets underground.

Many other factors could affect the situation, Dunlap said. Gas can create pressure underground, as can interactions between freshwater and heavier salt water. Produced water can be five to eight times saltier than ocean water.

“There’s been such an increase in disposal of produced water over the past decade, there’s an overwhelming amount of water being disposed,” said Dominic DiGiulio, an environmental consultant and geoscientist who worked for 30 years at the Environmental Protection Agency. “That pressure has to go somewhere. So if there’s a well penetration then it’s going to move freely up that well penetration.”

Most typically, old oil wells leak gas, which is naturally buoyant. Leaking water is less common, according to Dwayne Purvis, founder of Purvis Energy Advisors, but has been known to occur “under varying combinations of unique conditions.”

He pointed to examples in California related to the injection of steam for oil recovery, and in Pennsylvania , where water from old coal mines has flowed through abandoned oil wells to the surface. In Pennsylvania, the Department of Environmental Protection has also investigated “ frac-outs ,” which occur when water being used to frack a well “communicates” with an abandoned well and then contaminates well water far from the fracking site.

In any case, Purvis said, “fluid pressure must suffice to lift the fluids to the surface.”

On Wight’s ranch the latest blowout continues to flow. Measurements indicate the water is moderately salty, and Wight can only watch helplessly as it seeps into his land.

“The salt poisons the ground and nothing will grow after that,” he said. “There’s not a lot you can do to remediate salt contamination.”

Grassy Narrows First Nation files lawsuit against Ontario, federal governments over mercury contamination

Superior court challenge alleges governments fail to protect first nation treaty rights.

Social Sharing

A First Nation in northwestern Ontario that has faced decades of mercury poisoning is suing the provincial and federal governments, arguing they've failed to protect its treaty rights.

Asubpeeschoseewagong Netum Anishinabek First Nation — known as Grassy Narrows — filed the lawsuit in Ontario's Superior Court of Justice on Tuesday morning.

It argues the governments have violated their duties under Treaty 3 by failing to protect against or remedy the effects of mercury contamination in the English-Wabigoon River system.

The allegations in this lawsuit haven't been tested in court.

Contamination of the river system dates back to the 1960s and '70s  when Dryden's paper mill in northwestern Ontario dumped an estimated nine tonnes of mercury into the water.

Generations of people have consumed fish from the river. According to a previously reported study by medical specialists, about 90 per cent of the community of roughly 1,000 people experience symptoms of mercury poisoning. They include Chief Rudy Turtle.

"Our mercury nightmare should have ended long ago, but it has been longer and worse because of the government's failure to live up to its obligations," Turtle said in a news release on Tuesday.

'A test of ... commitment to truth'

For years, environmental advocates have called for the river to be cleaned up and the mill to be shut down.

In late May, a new study from Western University in London, Ont., revived these demands with a report suggesting mercury contamination in the river system has been made worse by ongoing industrial pollution.

"Dryden Fibre Canada took over operations for the mill last August. We operate in compliance with extensive environmental regulatory requirements," said Dianne Loewen, a spokesperson for Dryden Fibre Canada, in an email to CBC News late Tuesday afternoon. "Regarding this morning's announcement by Grassy Narrows — we have not yet seen the filing and will not be commenting."

Grassy Narrows lawsuit targets 'environmental racism' of mercury poisoning

"The government has egregiously violated its obligations to Grassy Narrows by failing to ensure that Grassy Narrows people could safely practise their right to fish — a cornerstone of Grassy Narrows' sustenance and Indigenous way of life," says a statement from the First Nation that was also issued Tuesday.

"This case will be a test of Ontario's and Canada's commitment to truth, reconciliation and justice following one of Canada's worst environmental and human rights catastrophes." 

Calls to end environmental racism

During a news conference in Toronto on Tuesday morning, Kiiwetinoong MPP Sol Mamakwa said the lack of government action is perpetuating the effects of colonialism on Grassy Narrows people.

"When we talk about environmental genocide, this is what it looks like," Mamakwa said.

Judy Da Silva is a Grassy Narrows grandmother and the community's environmental health co-ordinator. She says she also experiences symptoms of mercury poisoning, which include loss of co-ordination, trouble swallowing, and a loss of sensation in her hands and feet. 

"Our people were proud fishermen and land users and hunters, and then this poison came and took all that away," Da Silva said in an interview with CBC News.

She thinks back to summer 2000, when the Walkerton water crisis made national headlines after seven people died and about 2,300 others became ill from Canada's worst E. coli contamination.

"They got compensated so quickly and then Grassy's been going through this for decades, and still there's no resolution," she said. "I think it's environmental racism."

Federal leaders respond

In 2017, the federal government committed to building a Mercury Care Home in Grassy Narrows. The same year, the Ontario government committed $85 million to fund mercury cleanup and remediation efforts in the English-Wabigoon River system.

About seven years later, the river remains toxic. Construction on the Mercury Care Home is expected to start this summer and take two to three years to complete.

In Ottawa on Tuesday, Minister of Indigenous Services Patty Hajdu told reporters she understands the frustration that has led Grassy Narrows to go through the courts.

"I'm sure they're seeing it as a part of a broader effort to ensure that this kind of environmental racism doesn't continue," Hajdu said.

Minister acknowledges frustration of Grassy Narrows First Nation following launch of lawsuit

Ottawa has now committed $146 million for the construction and operation of the Mercury Care Home, she said. While the protection of water falls under provincial jurisdiction, Hajdu did point to Bill C-61,  an act respecting water, source water, drinking water, wastewater and related infrastructure on First Nation lands , as a key way of preventing future harm.

CBC News reached out to the Ontario government for comment on the lawsuit and received an emailed response from Keesha Seaton, spokesperson for the Ministry of the Attorney General, late Tuesday afternoon.

"As this matter is subject to litigation, it would be inappropriate to comment," Seaton said.

A spokesperson for the federal Office of the Minister of the Environment and Climate Change also provided CBC News with an emailed statement on behalf of Hajdu and Minister of the Environment and Climate Change Steven Guilbeault.

• First Nations Land Defence Alliance says no nuclear waste facility without First Nations consent

"We cannot comment on the legal case as it is before the courts. It is extremely important to the government of Canada to do its part in responding to this crisis, and we will be there to work with Grassy Narrows and Wabaseemong Independent Nations every step of the way," wrote spokesperson Kaitlin Power.

Federal NDP Leader Jagmeet Singh also reacted to the Grassy Narrows lawsuit while addressing reporters on Parliament Hill.

"It's an ongoing example of Indigenous communities receiving second-class treatment," Singh said of the persisting mercury poisoning.

"This is Canada's fault and Canada must step up."

Lawsuit seeks to restore 'way of life'

Grassy Narrows, about 150 kilometres from Dryden near the Ontario-Manitoba border, is being represented by both Toronto-based firm Cavalluzzo LLP and Ratcliff LLP out of Vancouver.

At this point, there is no set dollar amount for how much compensation the First Nation is seeking. However, the types of remedies relate to restoring the environment, "upon which their health, and their livelihoods and their treaty rights depend," Adrienne Telford, co-lead legal counsel with Cavalluzzo LLP, said in an interview with CBC News.

"Grassy Narrows is a community in crisis," Telford said. "They require significant financial, and socioeconomic and health supports to allow community members to restore their health, and their well-being and their way of life."

"If this was Ontario cottage country, the river would have been cleaned up decades ago, the pollution would have stopped and the harms properly compensated."

Ontario commits to 'correcting this historic wrong'

When pressed by Kiiwetinoong MPP Sol Mamakwa during Monday's question period in the Ontario Legislature, the minister of the environment, conservation and parks, Andrea Khanjin, said the government is committed to remediating the mercury contamination.

Technical experts with the ministry have met with First Nations leaders and those who led the Western University study — though additional work is needed before the researchers' report is finalized, Khanjin said.

Is Ontario doing enough to address mercury contamination in the English-Wabigoon River system?

Sandy Shaw, MPP for Hamilton West—Ancaster—Dundas and NDP environment, conservation and parks critic, called that answer "disappointing."
