What Causes Water Pollution?


What Causes Water Pollution? - Water pollution refers to the changes in the physical, biological, and chemical conditions of the water bodies that would disrupt the balance of the ecosystem.

Like other types of pollution, water pollution results when a large amount of waste coming from different sources of pollutants can no longer be accommodated by the natural ecosystem. Consequently, when the wastes are not destroyed as fast as produced, they make other organisms that are not beneficial to humans and many. But that's not all. Learn more about what causes water pollution. Actually there is a reason behind what causes water pollution. However, it is important to familiarize yourself with the two main categories of water pollution. Some pollution comes directly from one specific location. Type of pollution is called point source pollution such as sewage pipes that drain polluted water into rivers and farmland. Meanwhile, non-point source pollution is pollution that comes from large areas like gasoline and other debris from the highway that goes into lakes and rivers.



What are the causes of water pollution? Who should be responsible for causing the harm brought by their pollutants? How do these sources of pollution pollute different bodies of water?

One of the main causes of water pollution that has caused serious environmental health problems and is a pollutant that comes from chemical and industrial processes. When factories and manufacturers pour chemicals and livestock wastes directly into rivers and streams, the water becomes poisonous and oxygen levels are depleted causing many aquatic organisms die. These wastes include solvents and toxic substances. Most of the waste is not biodegradable. Power plants, paper mills, refineries, automobile factories dispose waste into the river.

The hot water from the power plant is called thermal pollution. This kills aquatic animals and plants by reducing the oxygen content of the water. Power plants use water to cool their engines, thus changing the temperature of the water.



Aside from thermal pollution, there are also organic and inorganic pollutants. Organic wastes include refuse from slaughter houses, fish and meat canning factories, and leather tanning companies, manufacturing plants, pesticides and crude oil companies. Since organic wastes are decomposed by microorganisms, most of the oxygen dissolved in the water used and the exhaust starts to stink.

Inorganic wastes include toxic and corrosive substances such as acids, heavy metals, mercury, cadmium and lead that can interfere with normal body processes. Battery manufacturers, mining, paper mills increase the concentration of mercury making the water dangerous and poisonous to most things living.

Another cause of water pollution from pesticides. Agricultural pesticides poison aquatic plants and animals. Animal manure, chemical fertilizers, phosphate detergent pollutes water by providing excess nutrients. Pollution is known as eutrophication. This greatly increases the growth of algae in water thereby reducing the amount of oxygen levels in the water caused the death of many aquatic organisms.

Water is also polluted by garbage specifically plastics and other plastic-like substances. Some plastic like nylon can fish and other marine animals involved. Plastics that have broken into smaller pieces can be eaten by sea creatures which may cause their death. Since plastic is non-biodegradable, it will continue to kill more fish.

One of the many causes of water pollution is derived from household waste. Because no one wants to live in polluted areas, near the dumpsite or a landfill, waste water and untreated dirt washed from the home polluting different bodies of water. Most developing countries practice this type of sewage disposal. Even in developed countries to poor discharge canal treated to cause the main body of water. The danger is when the sewage pipes break and contaminate drinking water. When this happens, the damage will open a wide range of waterborne diseases that will surely pose a danger to consumers.

Last pollution of the water causes personal care and household products. Shampoo, lotion, moisturizer, hair dye, bleach, detergent, fabric softener, and many others contribute to air pollution. Human waste is not the only one who entered into the gutter. This product is also joining the wastewater pollutes rivers, streams, and lakes.

Although the world is full of water, only three percent of it is drinkable. Included in the 3% of drinking water sources are rivers, spring, rivers, lakes, and waterfalls are constantly threatened and contaminated by various factors that cause water pollution. If the sources of water pollution are not controlled, this basic necessity will eventually become a rare commodity only a few can afford to have.
