Water pollution is a major concern that is caused by many different factors. Oil spills and leaks are a significant cause of water pollution, often caused by oil drilling operations in the ocean or ships that transport oil. Chemicals and pesticides used by farmers to protect crops from bacteria and insects can also seep into groundwater, harming animals, plants, and humans. Rising temperatures due to global warming are also a major concern in terms of water pollution.

What You'll Learn
Oil spills and leaks from drilling and transport
Water pollution is a major concern as it is toxic water that cannot be drunk or used for essential purposes like agriculture and causes diseases like diarrhoea, cholera, dysentery, typhoid and poliomyelitis. Water is a universal solvent that can dissolve many substances, and large oil spills and oil leaks are a major cause of water pollution. Oil drilling operations in the ocean and ships that transport oil are the most significant causes of water pollution. In England and Wales, there are about 3,000 pollution incidents involving oil and fuel each year. Oil makes drinking water unsafe and a substantial amount of oil released into oceans or rivers will destroy marine life and the ecosystems that support them.

Chemicals and pesticides from farming
Water pollution is a major concern as it is water whose composition has been changed to the extent that it is unusable. 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.
Large oil spills and leaks are some of the most significant causes of water pollution. These are often caused by oil drilling operations in the ocean, but nearly half of the estimated 1 million tons of oil that makes its way into marine environments each year come not from oil tankers, but from land-based sources like factories, farms and cities. In England and Wales, there are about 3,000 pollution incidents involving oil and fuel each year.
In order to protect their crops from bacteria and insects, farmers often use chemicals and pesticides. When these substances seep into the groundwater, they can harm animals, plants and humans.
When it rains, the chemicals mix with rainwater, which then flows into rivers and streams that filter into the ocean, causing further water pollution.
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.

Global warming and rising temperatures
Rising temperatures due to global warming are a major concern in terms of water pollution. Water is one of the most important elements on Earth when it comes to sustaining life. Unfortunately, it is also extremely susceptible to pollution. Water is a universal solvent that can dissolve many substances. While this is a wonderful quality that we take advantage of for everyday tasks such as cooking, cleaning and taking medication, it is also the exact quality that causes water to become polluted so easily.
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. 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.

Bacteria, viruses, parasites and faecal waste
Water pollution is caused by a variety of factors, including bacteria, viruses, parasites, and faecal waste. These substances can enter water sources through natural processes or human activities.
Bacteria are microscopic organisms that can survive and multiply in water. Some bacteria are harmless, but others can cause diseases such as diarrhoea, cholera, dysentery, typhoid, and poliomyelitis. These pathogens can contaminate water sources through faecal waste or poor sanitation.
Viruses are even smaller than bacteria and can only replicate inside the cells of living hosts. They can cause various illnesses and enter water sources through contaminated faecal matter.
Parasites are organisms that live on or inside a host and can cause disease. They can enter water sources through contaminated faecal waste or poor sanitation.
Faecal waste is a significant source of water pollution. It can contain harmful bacteria, viruses, and parasites that can cause disease. Faecal waste can enter water sources through sewage systems or poor sanitation.
To prevent water pollution, it is essential to improve sanitation and treat wastewater before it is discharged into water sources. Additionally, reducing the use of chemicals and pesticides in agriculture can help prevent water pollution.

Nitrates, phosphates and plastics
Water pollution is a major concern and is defined by the World Health Organisation (WHO) as water whose composition has been changed to the extent that it is unusable. Water pollution is caused by many different substances and can be invisibly harmful. Nitrates, phosphates, and plastics are some of the main water pollutants.
Nitrates are a fertiliser and pesticide that protects crops from bacteria and insects. When these substances seep into the groundwater, they can harm animals, plants, and humans. Phosphates are chemicals that mix with rainwater and then flow into rivers and streams that filter into the ocean, causing further water pollution.
Plastics are also a major cause of water pollution. Large oil spills and leaks are some of the most significant causes of water pollution. These are often caused by oil drilling operations in the ocean, but nearly half of the estimated 1 million tons of oil that makes its way into marine environments each year come not from oil tankers, but from land-based sources like factories, farms, and cities.
