What Are The Causes Of Water Pollution?

One of the most important resources of our planet is water. Clean water is essential to our communities, economy, and above all, our health. In fact, humans are made up of more than 60% water and they need clean water to survive.

Unfortunately, much of the water on the planet is polluted, making it one of the major crises facing the world today. There are many causes of water pollution and several measures should be taken to preserve this precious resource.

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. That’s why small amounts of water and aquatic organisms are tested to determine water quality.

What Is Water Pollution Causes?

It can also be caused by nature, such as the filtering of mercury from the earth’s crust and the pollution of seas, rivers, lakes, canals and reservoirs. However, the most common cause of poor water quality is human activities and their consequences. Water pollution has many causes.

1. Rapid Urban Development

Whenever a large number of people gather in a densely populated area, physical disturbance of the land follows. The building of new roads, houses, and industries affect the cleanliness of the water through the use of detergents, chemicals, and exhaust emissions. When it rains, these chemicals run into rivers and streams and eventually into drinking water.

2. Sewage and Wastewater

According to the United Nations report, more than 80% of the world’s wastewater flows into oceans and rivers without treatment. In some less developed countries, this figure is more than 95%.

Used water is wastewater. It comes from our sinks, showers and toilets (think sewage) and from commercial, industrial and agricultural activities (think metals, solvents and toxic sludge).

The term also includes stormwater runoff that occurs when stormwater carries road salt, oil, grease, chemicals, and debris from impervious surfaces into waterways.

In the United States, wastewater treatment plants treat approximately 34 billion gallons of wastewater per day. It reduces pathogens and pollutants such as phosphorus and nitrogen in wastewater and heavy metals and harmful chemicals in industrial waste and discharges treated water into waterways.

That’s when everything goes well. But the EPA estimates that our nation’s wastewater treatment systems are wearing out and wearing out fast, releasing more than 850 billion gallons of untreated wastewater each year.

3. Global warming

Global warming due to the release of CO2 causes the water to heat up and decrease its oxygen content. Rising temperature due to global warming is one of the main concerns in terms of water pollution.

Global warming causes the water temperature to rise, which can kill aquatic animals. Big blackouts cause more pollution of the water source and exacerbate the problem.

There are many everyday ways to help reduce global warming and also help reduce water pollution. These methods include recycling, car collection and using CFL bulbs in the home.

4. Deforestation

Deforestation can deplete water resources and produce organic residues that become breeding grounds for harmful bacteria. Deforestation weakens this process, leading to irregular rainfall patterns including drought and flooding. Deforestation can occur locally, but its impact is global.

Healthy forests act as filters that prevent water from becoming polluted. Strong roots anchor the soil against erosion, and the forest floor material helps absorb nutrients and sediment. However, when forests are disturbed and degraded, sediments flow into streams and pollute the water.

5. Industry, agriculture and livestock farming

Discharge of chemicals from these parts is one of the main factors of water erosion.

Large factories are notorious for dumping chemicals into the oceans. Very toxic substances such as detergents, polychlorinated biphenyls and lead enter our environment every day.

Between those trying to keep their gardens green and weed-free, and farmers coping with a growing population, fertilizers play an important role in polluting our planet’s water. The result is dangerous algae and ultimately the extinction of many aquatic plants and fish.

6. Fuel spillages/ Oil Spills

Transportation and storage of oil and its derivatives are subject to leaks that contaminate water sources.

The old phrase “like oil and water” is used to describe two things that do not mix easily or at all. As the saying goes, water and oil do not mix and oil does not dissolve in water. Large oil spills and spills, although often accidental, are a major source of water pollution. Spills and spills are often caused by offshore oil drilling operations or ships carrying oil. wild life.

7. Radioactive Waste

Radioactive waste from facilities that produce nuclear energy can be very harmful to the environment and must be disposed of properly. This is because uranium, the element used to generate nuclear power, is a highly toxic chemical.

Unfortunately, accidents still occur at these facilities and release toxic waste into the environment. The coal and gas industry is not great in many ways. This is one of the main driving forces behind the development of alternative clean energy sources such as solar and wind.
