Here are 100 facts related to water pollution causes and effects. Let’s learn together
Before unveiling the 100 water pollution facts, let’s have a basic understanding of water pollution. Water as a significant resource of survival is uniquely vulnerable to pollution. Water pollution happens when toxic substances from cities, towns, or factories get dissolved in water bodies. This mix of toxic substances in water causes water pollution, which then becomes a cause of alarm for all the living beings on Earth. UNESCO defines water pollution as an incident wherein any substance that is not present in water is dissolved in water in an undesirable concentration.
An increase in human population, urbanization, and endless industrialization have contributed most to contaminated water, the natural resource which is essential for all life forms to sustain and survive.
Why is Water Pollution harmful?
The failure to meet basic survival needs by having safe-drinking water is considered as a cost that we paid in the name of development. The UN, signed the Millennium Development Goals in 2020 wherein a pledge was taken by the countries of the world, to lessen by half the proportion of people without access to safe drinking water. It is significant to focus on achieving this goal because the availability of clean and safe drinking water can solve many health issues and thereby eradicate poverty and inequality.
According to a recent report by NITI Aayog, it was stated that from 2018, India has been suffering the “worst water crisis in history”. A recent survey report estimated that 70% of surface water in India is unsafe for consumption, with an estimation of 40 million liters of waste being added to water bodies every day around the nation. This has resulted in numerous deaths and stress on all living beings.
Water pollution is a threat to life, and honestly speaking: it kills.
Water Pollution Facts and Statistics
Here are 100 water pollution facts for water pollution facts and statistics:
- Water being a ‘universal solvent’ makes it very vulnerable to pollution.
- Annually, approximately 14 billion pounds of garbage, mostly plastic, is dumped into the world’s water bodies.
- The four main causes of water pollution in India are – Agriculture, social-religious beliefs, human activities, and industrial discharge.
- Water Pollution can be broadly categorized into three categories – surface water pollution, marine water pollution, and groundwater pollution.
- The problem of water pollution makes it important to have programs for testing and treatment of contaminated water.
- More than a quarter of the world lacks access to clean water with Uganda being on top of the chart. Approximately 40% of the population of Uganda travels 30 minutes and more to get access to clean water every day.
- 70% of the lakes and rivers of China are polluted, While 80% of India’s water bodies are severely polluted.
- Another heartbreaking fact hidden behind the big problem of water pollution is that in India more than 1000 children die due to the lack of access to safe water every day.
- Water pollutants include both organic and inorganic factors.
- Waste from trees, plants, animals, etc. are organic factors of water pollutants.
- Inorganic factors include ammonia, chemical waste from factories, and discarded cosmetics.
- A significant fact that we are mostly unaware of is only about 1% of Earth’s water is freshwater, the rest is salty water.
- Surface water refers to the top layer of any water body. The problem of surface water pollution occurs because of industrial waste.
- Surface water contains certain organisms that can break down pollutants into harmless substances giving it a tendency to clean itself.
- Globally, 80% of the population with a lack of access to safe water belongs to rural areas, and 50% of the total population who is having unsafe water sources belongs to Africa.
- When waste is washed or blown into the oceans causing immense destruction to marine life it is called marine water pollution.
- While groundwater is the most reliable source for irrigation and agriculture, it is also suspected to be polluted when man-made products get into it.

- One of the sources of water pollutants refers to ‘point sources’ – a pipe source that is used in releasing industrial and domestic sewage waste is called ‘point source’.
- When a variety of water pollutants enter water bodies without any confined source or area it is then called a ‘dispersed source’ of water pollutants.
- While point sources of water pollution are easy to control, it is a task to control dispersed sources of water pollutants.
- Water pollution is measured by analyzing water samples.

- As per a 2012 UN report on nutrients in water bodies, the number of lakes with harmful algal bloom will increase by approximately 20% causing more harm to these water bodies.
- Humans add as much nitrate into the environment as plants and that is the reason why the growth of the human population also becomes a cause of water pollution.
