Water Pollution

Water pollution occurs when harmful, or potentially harmful, effects result from the entry into the ocean of chemicals, particles, industrial, agricultural and residential waste, noise, or the spread of invasive organisms. Water pollution is caused by many mediums. Here are the top 10 causes of water pollution:

  1. Air Pollution: The air pollution is formed by emission of harmful gases into air. Because of rain, air waste is returned to the ground and other water sources.
  2. Farm Pollution: River water is used for irrigation by most farmers. But pesticides and other toxic chemicals are used by farmers to control diseases and pest invasion. These toxins reach the river canals which supply water to the cities and towns it runs through.
  3. Plastic Waste: Plastic pollution occurs due to accumulation of plastic waste for long periods of time in the sea beds, as it decomposes slower, and people don’t dispose of their waste efficiently.
  4. Industrial Waste Release: Most industries release their processing waste into the rivers or oceans, depending on which they’re closer to. This method is used because it’s cost effective and easy for most industrial companies.
  5. Human Dumping: Humans are the main reason for all pollution. We dump waste, pollute the air with smoking, and find it hard to recycle or reuse our waste efficiently. Our waste, in one way or another, finds its way to our dams, rivers and oceans.
  6. Land Water Flow: Pollution during rains due to flow of rain water from contaminated land into rivers. This flow collects all the possible waste and leaves it in rivers, oceans and other water outlets.
  7. Broken Drainage Systems: This is when sewage water and the public water supply mix up. This is common in cities where water is pumped from distant places, and is caused by sewage pipe leakages and mixing of pure water and sewage water. This happens when both sewage and pure water supply pipes are passing close to each other. This is one of the major reasons for infectious diseases.
  8. Groundwater Contamination: Water on the land is absorbed by the soil, along with any excess chemicals or toxins exposed on the land. This happens at places of heavy land pollution, such as industrial or city areas. These harmful substances on the land percolate into deep ground layers causing pollution.
  9. Fisheries: Fisheries are a part of agriculture and mainly depend on rivers. Many chemicals and drugs are used to enhance fish growth. But since these are collected with rivers, all the waste is flowed out into rivers.
  10. Leakage of petroleum and other waste oils from vehicles and mechanic sheds onto local roads. This waste is mixed with nearby water sources.

There are many ways to purify water, but one way to ensure our water is clean is by abstaining from pollution.
