Be aware about Water pollution diseases

Living organisms (as long as they are induced by human activity; please note that some waters unaffected by human activity may still be naturally polluted with some of these organisms – in which case, the caused diseases may not be seen as pollution diseases):Pathogens – including a variety of living organisms (usually from animal waste) such as various species of viruses, bacteria, fungi and intestinal worms. Their presence in water, many times, remains unnoticed.Algae – some types of algae are toxic and may overgrow due to the presence of nitrates and phosphates in runoff water (especially agricultural runoff); such overgrowth is usually referred to as “red tide” or “brown tides”. Their toxin may affect the food chain including fish and birds, and ultimately humans. Oxygen depletion in polluted water is another serious problem responsible for killing fishes. All over the world. Infectious diseases caused by pathogens (usually microorganisms) from animal fecal origins, of which the most common occur in developing countries involving:

  • Typhoid
  • Giardiasis
  • Amoebiasis
  • Ascariasis
  • Hookworm

 Diseases caused by polluted beach water including:

  • Gastroenteritis
  • Dhiarrhea
  • Encephalitis
  • Stomach craps and aches
  • Vomiting
  • Hepatitis
  • Respiratory infections

 The most common ways of polluting the water include:

  • Waste disposal:
    • directly into waste-streams
    • in the land from which contaminants may leach into the groundwater below
  • Urban and agricultural runoff;
  • Animal wastes could also add dangerous pathogens (usually microbial groups, viruses and intestinal parasites) into the water;
  • From air via acid rain - water can get polluted with air contaminants (that have sometimes traveled long distances – such as the case of Hg) that reach the land and water via acid rain (during precipitation, air pollutants may get dissolved in the water drops and as a result they may acidify the water which is why the polluted rain water is referred to as “acid rain”).
