Water pollution

The water in a person's life Water is the basis of life on Earth. The

primary role of water in the life of all living beings, and humans in particular, due to the fact that it actually is the medium in which the flow and all vital processes. Here are just a small and is not a complete list of "duties" of water in our body:

Regulates body temperature Moistens the air when breathing Pitatelnyhveschestv and delivers

oxygen to all body cells Protects and buffers the vital organs Helps convert food into energy Helps nutrients assimilated bodies Removes toxins and waste processes of

life

It hit its elements, making it unfit for human consumption. This can occur at all stages of the cycle of water, and even in an atmosphere where water is present in the form of clouds.

The origin of the contamination can be:

utilities (sewer)industrial,agricultural,natural.

Thus contaminatedsurface,underground,ground water.

Water pollution

The causes and sources of pollutionPollutants into the water in different

ways, but always with the participation of the person: as a result of accidents, deliberate dumping of waste, spills and leaks, and contamination of rivers, streams, lakes, seas and oceans of various physical, chemical or biological substances. Water pollution has many causes:

wastewater solid waste eutrophication The toxicity of inorganic waste The toxicity of inorganic waste Microbiological contamination pesticides oil spill

Methods of dealing with water pollution

Must simultaneously pursue the following three objectives:

preserve the integrity of the ecosystem due to conduct economic activity on the basis of the principle, provides for the protection of aquatic ecosystems, including living resources and their effective protection against all types of degradation within the catchment area

protection of public health, which includes not only the supply of drinking water that does not contain pathogenic microorganisms, but also control of the vector in the aquatic environment

human resource development is the key to capacity-building and a prerequisite for establishing activities to regulate water quality
