9.3.4. Water contamination

Water pollution or water pollution

The water is the fundamental component of living beings and, therefore, a basic substance for life.
The natural water cycle has a great capacity for self - purification, cleaning natural contaminants (pollen, dust, etc.) and artificial (if they are not very important), through its natural movement. But, even so, it does not always have the necessary quality to be used by humans.
The water is contaminated when its natural composition and altered properties (color, smell, taste, temperature, etc.) by the introduction of contaminants (substances or forms of energy) that prevent normal use.
Traditionally, water has been the natural receptor of all types of waste, but this contamination is not limited to surface waters (rivers, lakes, seas, etc.), but also affects groundwater.
