The document discusses water pollution, its natural and human-induced sources, and the profound effects it has on health and the environment. It outlines various types of pollutants, such as organic and inorganic chemicals, sediments, and pathogens, emphasizing the dangers of both isolated and diffuse pollution sources. The text also highlights the significant correlation between contaminated water and infectious diseases, urging the need for monitoring and innovative solutions for water disinfection and contamination prevention.

5. ● Some sources of water pollution are natural. For example,
mercury in the Earth's crust and the oceans produce pollution of
natural way of these.
● The sources are very dispersed and don't cause high
concentrations of pollution, except in some very specific places.
The man-made pollution is more dangerous than the natural.
● Natural factors can't be easily controlled and can have a
significant impact on the quality of a water source. The factors
are, for example, the weather, fires, geology and microbiology
