Water pollution occurs when harmful substances or contaminants are present in water bodies, including surface water, ocean water, and groundwater. Water pollution can have wide-ranging and detrimental effects on human health, animal health, and the environment. There are many types of water pollution, differentiated by the type of water source that’s polluted or the nature of the pollutant (chemical, microbiological, etc.).

Release of substances into bodies of water that make water unsafe for human use
Water pollution is the release of substances into bodies of water that make water unsafe for human use and disrupt aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste, petroleum, and disease-causing microorganisms. 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.
Water pollution occurs when harmful substances or contaminants are present in water bodies, including surface water, ocean water, and groundwater. Because water is an essential resource that is a key part of any ecosystem, water pollution can have wide-ranging and detrimental effects on human health, animal health, and the environment.
The World Health Organisation (WHO) says that polluted water is water whose composition has been changed to the extent that it is unusable. In other words, it is toxic water that cannot be drunk or used for essential purposes like agriculture, and which also causes diseases like diarrhoea, cholera, dysentery, typhoid and poliomyelitis that kill more than 500,000 people worldwide every year. The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, faecal waste and even radioactive substances. These substances do not always change the colour of the water, meaning that they are often invisible pollutants.
Water pollution is also frequently categorised as point source or nonpoint source pollution. Point source pollution comes from a specific identifiable source such as a factory or sewage treatment plant.
Water pollution can have wide-ranging and detrimental effects on human health, animal health, and the environment.

Water pollution is also frequently categorised as point source or nonpoint source pollution. Point source pollution comes from a specific identifiable source such as a factory or sewage treatment plant. Nonpoint source pollution is caused by runoff from agricultural, urban, and industrial activities.
Water pollution can have detrimental effects on animal health as well. Animals that drink polluted water can suffer from illnesses and death. Aquatic animals are also affected by water pollution, as it can disrupt their natural habitats and food sources.

Water pollution from industrial activities and toxic waste
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. Human activities that generate domestic sewage and toxic waste cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances.
The effects of water pollution from industrial activities and toxic waste can be severe. It can lead to the contamination of drinking water, which can cause illnesses such as diarrhoea, cholera, dysentery, typhoid, and poliomyelitis. It can also lead to the destruction of aquatic ecosystems, which can have a devastating impact on the natural environment and human health.
To address water pollution from industrial activities and toxic waste, it is important to implement strict regulations and enforcement measures to reduce the release of pollutants into water bodies. This can include treating industrial effluents before they are released into the environment, improving sewage treatment processes, and preventing oil spills. Additionally, raising awareness about the causes and effects of water pollution can help to encourage individuals and communities to take action to reduce their contribution to water pollution.

In other words, it is toxic water that cannot be drunk or used for essential purposes like agriculture.
Petroleum is another pollutant that can cause devastating impacts on surrounding ecosystems. Oil spills can occur due to human activities like shipping and drilling. These spills can contaminate water with toxic substances that can harm aquatic life and human health.
Water pollution can have wide-ranging and detrimental effects on human health, animal health, and the environment. It can also lead to eutrophic "dead zones" where aquatic life cannot survive because of a lack of oxygen.
To prevent water pollution, it is essential to reduce the release of contaminants into water bodies. This can be achieved through proper waste management, sewage treatment, and oil spill response measures. Additionally, education and awareness about the impacts of water pollution can help individuals and communities take steps to protect water resources.
