Water pollution is a pressing issue that affects one in three people on the planet, according to the United Nations. It occurs when harmful substances contaminate a body of water, degrading water quality and rendering it toxic to humans or the environment. With that in mind, here are three problems that can result from polluted water:
1. Health issues: Polluted water can cause a range of health issues, from skin rashes and pink eye to more severe problems like cancer, hormone disruption, and altered brain function. According to the United Nations, water pollution causes more deaths annually than all forms of violence, including war.
2. Environmental damage: Water pollution can destroy aquatic ecosystems, trigger harmful algal blooms, and contaminate the food chain. It can also lead to eutrophication, creating dead zones where aquatic life cannot survive due to a lack of oxygen.
3. Economic impact: Polluted water can negatively affect sectors such as commercial fishing, recreational businesses, and tourism, stalling economic growth and exacerbating poverty in many countries.
| Characteristics | Values |
|---|---|
| Health | Polluted water causes the spread of diseases such as typhoid, cholera, dysentery, skin rashes, pinkeye, respiratory infections, hepatitis, giardia, cholera, and diarrhoea. According to the United Nations, water pollution causes more deaths than all types of violence, including war. |
| Environment | Water pollution destroys biodiversity and depletes aquatic ecosystems. It triggers the proliferation of phytoplankton in lakes and contaminates the food chain. It also results in eutrophication, or "dead zones", where aquatic life cannot survive due to a lack of oxygen. |
| Economy | Polluted water negatively affects sectors such as commercial fishing, recreational businesses, tourism, and property values, all of which rely on clean water. It also impacts the global economy by stalling economic growth and exacerbating poverty in many countries. |

Oil spills and leaks
Large oil spills are major disasters that occur when pipelines break, big oil tanker ships sink, or drilling operations go wrong. The consequences of these large spills can be felt for decades, with ecosystems and economies suffering long-term damage. Oil spills can occur anywhere oil is drilled, transported, or used. The transportation and transfer of oil increase the risk of spills, as the process often involves multiple transfers between ocean tankers, pipelines, trains, and tanker trucks. The more transfers that occur, the higher the risk of an accidental spill.
Oil spills harm aquatic life in two main ways: fouling and oiling. Fouling or oiling occurs when oil physically harms a plant or animal. For example, oil can coat a bird's wings, leaving it unable to fly, or it can strip away the insulating properties of a sea otter's fur, making the animal vulnerable to hypothermia. Oil spills can also cause the proliferation of phytoplankton in lakes, which can eventually result in eutrophic "dead zones" where aquatic life cannot survive due to a lack of oxygen.
In addition to the immediate harm caused by oil spills, the cleanup process can also lead to further environmental damage. Burning oil spills to clean them up releases hydrocarbons, which contain sulfur and nitrogen. These mix with water vapour in the atmosphere and fall back to the earth as acid rain, causing damage to water bodies, plants, and even buildings.

Industrial waste
The quality and quantity of wastewater generated depend on the type of industry. It can contain non-biodegradable waste such as heavy metals, pesticides, and plastics, as well as biodegradable compounds like paper, leather, and wool. Industrial wastewater can be toxic, reactive, carcinogenic, or ignitable. It can also contain hazardous materials such as ammonia, solvents, and petroleum.
The improper treatment and direct release of hazardous industrial effluents into sewerage drains pollute groundwater and other major water bodies. This has adverse effects on the health of animals and aquatic life. For example, the intake of toxic heavy metals by aquatic fauna can cause detrimental health problems in other animals and ultimately in humans via the food chain. They can be teratogenic, carcinogenic, and can cause oxidative stress, organ damage, nervous system impairments, and reduced growth and development.
The natural process of eutrophication, which occurs over centuries, is sped up by industrial waste. This leads to toxic algal blooms, which decrease sunlight and lead to hypoxia (a lack of oxygen). As a result, fish die and biodiversity decreases. As the excess plant matter decomposes, carbon dioxide is released, leading to ocean acidification, which is harmful to marine life, including shellfish.

Sewage and wastewater
Sewage pollution is a global crisis that threatens both humans and natural ecosystems. It has been linked to the spread of diseases, with children and the elderly being particularly vulnerable. For example, the contamination of water by sewage can lead to the transmission of E. coli, resulting in diarrhea, kidney failure, and even death in severe cases. Cryptosporidiosis, commonly known as "Crypto", is another waterborne disease caused by a parasite found in contaminated water. It can lead to diarrhea, stomach cramps, nausea, and fever. Viral gastroenteritis, or "stomach flu," is also transmitted through contaminated water, causing watery diarrhea, vomiting, headache, fever, and abdominal cramps. Hepatitis A, a liver disease, is another consequence of sewage-contaminated water, exhibiting symptoms such as jaundice, fatigue, abdominal pain, nausea, and diarrhea.
Untreated and poorly treated sewage is a pressing issue, as it increases the concentrations of nutrients, pathogens, endocrine disruptors, heavy metals, and pharmaceuticals in natural ecosystems. This contamination has been observed in coral reefs, salt marshes, and fish-rich river systems, posing a significant threat to aquatic life and human health. Sewage can also promote algae growth, leading to eutrophic "dead zones" where aquatic life cannot survive due to oxygen depletion.
Furthermore, sewage and wastewater contribute to the pollution of our oceans, rivers, and lakes. The UN estimates that more than 80% of the world's sewage ends up in these water bodies untreated. This pollution includes plastic waste, with fishing boats, tankers, and cargo ships being significant contributors. Plastic pollution not only harms marine life but also enters the human food chain through the consumption of seafood.
To address the problems caused by sewage and wastewater, proper wastewater treatment and disposal are crucial. It is essential to ensure that wastewater from homes and industries is treated effectively before being released back into the environment. Additionally, reducing plastic consumption and properly disposing of chemicals, oils, and non-biodegradable items can help mitigate the negative impacts on our water systems.

Solid waste
Inadequate infrastructure, resources, or regulations in developing countries can lead to the intentional dumping of solid waste into bodies of water. This practice has severe consequences for the environment and aquatic life. Solid waste can also be carried by animals, wind, or rainfall into water sources, causing land pollution that eventually turns into water pollution.
The presence of solid waste in water bodies has several detrimental effects. Firstly, it is visually unappealing, detracting from the natural beauty of aquatic ecosystems. Secondly, and more importantly, solid waste can release harmful chemicals into the water, creating toxic or hazardous conditions. For example, plastics and electronic waste can break down and leach toxic substances, such as lead, mercury, and chromium, into the water. These chemicals can have detrimental effects on aquatic life and human health.
Additionally, solid waste can physically harm wildlife. Animals may become entangled in trash or ingest solid waste, leading to injuries or death. The accumulation of solid waste can also create obstacles and hinder the natural functioning of ecosystems. Furthermore, solid waste contributes to the destruction of biodiversity. It disrupts aquatic ecosystems and triggers the excessive growth of certain organisms, such as phytoplankton, leading to eutrophication and ""dead zones" where aquatic life cannot survive due to oxygen depletion.
To address the issue of solid waste pollution, it is essential to focus on proper waste management and disposal. This includes reducing, reusing, and recycling solid waste, as well as implementing effective waste treatment processes. By minimizing the improper disposal of solid waste, we can help protect aquatic ecosystems, preserve biodiversity, and ensure the safety and health of both wildlife and human populations that depend on clean water sources.

Microplastics
Primary microplastics are intentionally manufactured in small sizes for use in consumer products, such as cosmetics, biomedical products, and health and beauty products. These microbeads, as they are often called, are added as exfoliants to products like cleansers and toothpaste. Because of their small size, they can easily pass through water filtration systems and end up in bodies of water, posing a threat to aquatic life.
Secondary microplastics are plastic particles that break down from larger plastic materials, such as food wrapping, tires, and synthetic textiles. They can also come from larger plastic pieces that have broken apart or resin pellets used for plastic manufacturing. Over time, microplastics will likely degrade into even smaller nanoplastics through chemical weathering, mechanical breakdown, and the digestive processes of animals.
The presence of microplastics in water has been shown to negatively affect living organisms, especially aquatic species that are otherwise considered valuable sources of nutrients for humans. This contamination has been found in drinking water and kitchen salt, as well as in marine organisms, which can be dangerous for those who consume them. Humans who consume seafood are at risk due to the biomagnification of microplastics in marine wildlife.
