Have you heard the famous quote written by W.H.Auden, "Thousands have lived without love, not one without water"? According to the UN World Water Development Report, approximately 56% of industrial wastewater is discharged into the environment which further degrades water quality in surface & groundwater and causes water pollution.

In this article, we will examine the water pollution causes and how we can prevent it from spreading.

What is Water Pollution?

Water pollution occurs when we dump or discharge any kind of waste, including liquid and solid, into water. This kind of pollution can happen in a very personal way by humans or also by nature. Read on to find out more about it.

Types of Water Pollution

There are many different types of water pollution. Some common types include:

Chemical pollution

This type of pollution occurs when chemicals, such as oil, pesticides, and heavy metals, are introduced into the water.

Biological pollution

This type of pollution occurs when there is an excess of certain types of organisms, such as algae, in the water.

Thermal pollution

This type of pollution occurs when the temperature of the water is raised, often as a result of discharging hot water from factories or power plants.

Sediment pollution

This type of pollution occurs when soil and sediment are washed into the water, making it cloudy and difficult for plants and animals to survive.

Nutrient pollution

This type of pollution occurs when there are excess nutrients, such as nitrogen and phosphorus, in the water. These nutrients can lead to the growth of harmful algae blooms.

Radioactive pollution

This type of pollution occurs when radioactive substances, such as those found in nuclear power plants or uranium mines, are introduced into the water.

Microbial pollution

This type of pollution occurs when harmful microorganisms, such as bacteria and viruses, are introduced into the water.
Overall, water pollution can have serious consequences for the environment and human health. It is important to take steps to reduce water pollution and protect our water resources.

Causes of Water Pollution

There are many causes of water pollution. Some of the main causes include:

Discharge of untreated sewage and wastewater

This is a major cause of water pollution, as it contains a variety of harmful contaminants, including bacteria, viruses, and nutrients.

Industrial effluent

Industrial effluent is the main water pollution causes as they are difficult to treat. Many industries release harmful chemicals and pollutants into water bodies as a result of their manufacturing processes.

Agricultural runoff

Fertilizers and pesticides used in agriculture can find their way into water bodies and cause pollution.

Leakage from landfills

Landfills can leak a variety of contaminants, including heavy metals and organic compounds, into the surrounding soil and water.

Oil spills

Oil spills can contaminate water bodies and harm aquatic life.

Litter

Litter, such as plastic bags and bottles, can find their way into water bodies and cause pollution.

Acid rain

Acid rain, which is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, can acidify water bodies and harm aquatic life.

Effect of Water Pollution

Water pollution causes can have a range of negative effects on the environment and human health. Some of the main effects of water pollution include:

Harm to Aquatic Life

Pollutants in the water can harm or kill fish, amphibians, and other aquatic animals. This can lead to a decline in biodiversity and a reduction in the number of species living in an ecosystem.

Contamination of drinking water

Water pollution can contaminate sources of drinking water, making it unsafe for human consumption. This can lead to a range of health problems, including stomach illness, skin irritation, and neurological disorders.

Eutrophication

Eutrophication is a state of overpopulation in an aquatic environment, caused by a decrease in the availability of dissolved oxygen. This can occur as a result of either human or natural factors. In most cases, Eutrophication can be corrected by removing pollutants from the water, but it may take many years for the problem to go away completely.

Damage to crops

Water pollution can also affect agriculture, as polluted water can be used to irrigate crops. This can lead to crops that are contaminated with pollutants, which can be harmful to human health when consumed.

How to Prevent Water Pollution

There are several steps that individuals and communities can take to help reduce water pollution causes:

Properly dispose of waste

Properly disposing of waste, including household chemicals and pharmaceuticals, can help prevent these substances from entering the water supply and further reduce water pollution.

Reduce the use of fertilizers and pesticides

Reducing the excessive use of fertilizers and pesticides can help reduce the number of pollutants entering the water supply.

Support conservation efforts

Protecting natural areas, such as wetlands and forests, can help filter pollutants and prevent them from entering the water supply.

Properly maintain vehicles

Leaks and spills from vehicles can contribute to water pollution. Properly maintaining vehicles and disposing of automotive fluids properly can help prevent water pollution.
