Water pollution refers to changes in the physical, biological, chemical and conditions of any water that disrupts balance the ecosystem.

Like any other type of contamination, the results of water pollution, when a huge waste from different sources of pollution and can not be satisfied by the natural ecosystem. Therefore, when waste is not destroyed as they occur, other agencies do the bad man and many others. But not all. Learn more about the causes of water pollution.

There are actually many specific reasons underlying causes of water pollution. However, it is important to familiarize yourself with the two main categories of water pollution. Some pollution comes directly from a location. This type of pollution is called point source pollution such as sewage pipes contaminated water drained into the river and farmland. Meanwhile, the nonpoint source pollution is pollution that comes from large areas such as gasoline and other dirt roads that go into lakes and rivers.

What are the causes of water pollution? Who are the guilty parties be liable for damages suffered by their pollutants? How these different sources of pollution pollute waterways?

One of the main causes of water pollution has caused serious environmental and health problems are chemical pollutants and industrial processes. When the factories and manufacturers pour their chemicals and waste animals directly into streams and rivers, the water becomes toxic and deplete oxygen levels causing many water bodies die. These wastes include solvents and toxic substances. Most waste is not biodegradable. Power plants, paper mills, refineries, automobile factories dispose waste into the rivers.

The hot water from power plants is called thermal pollution. It kills aquatic animals and plants, reducing the oxygen content of water. The plants use water to cool their machines, which changes the temperature water.

Besides the thermal pollution is also organic and inorganic contaminants. The organic wastes include refuse from slaughterhouses, fish and canned meat, and leather tanning companies, factories, pesticide companies and crude oil. As organic waste decomposes by microorganisms, much of the oxygen dissolved in water is drained and the waste begins to stink.

inorganic waste include toxic and corrosive substances like acids, heavy metals mercury, cadmium and lead that may affect the normal process of the body. Manufacturers batteries, mines, factories role of increasing the concentration of mercury, which makes the water dangerous and poisonous to most living things.

Another cause of water pollution is pesticides. agricultural pesticide poison plants and aquatic animals. Manure, chemical fertilizers, phosphate-free detergent pollute water supplying excess nutrients. This contamination is known as eutrophication. This implies a growth of algae in water which reduces the amount of oxygen levels in water kills many aquatic organisms.

Water is also polluted by garbage plastics and specifically plastic-like substance. Some fish such as nylon plastic can entangle and other marine animals. Plastics have broke up into smaller pieces can be eaten by marine animals that may cause his death. Since plastic is not biodegradable, they continue to kill more fish.

Another cause of water pollution are wastewater from households. Since nobody wants to live in a contaminated area near a landfill or landfill, wastewater and untreated sewage are carried outside the home, various bodies of water pollutants. Most developing countries practice this type of wastewater treatment. Even modern countries were wrongly treated wastewater to channels that lead to large expanses of water. The danger is that sewage pipes were broken and debris can contaminate drinking water. When this occurs, breaking open a wide range of waterborne diseases, which will surely pose risks to consumers.

Last contamination between the causes of water are personal care and household products. Shampoo, lotion, moisturizer, hair dyes, bleach, detergent detergent, fabric softener, and many others contribute to water pollution. Human waste is not the only thing that will waste water. These products are also attached polluting wastewater streams, rivers and lakes.

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