4.  Water is included in physical environment and
very important component of all living animal and
human being and its necessary for life.
 Without water life is not possible.
 The amount of water in world is fixed.
 In 1500 million of water only about 0.2% is fresh
water.
 Good health safe water supply
 If quality of water raised ,disease rate decrease
 According to WHO in 1996 more than five million
of people die because of unclean water.

5.  Domestic use of water
 Public use of water
 Industrial use of water
 Agricultural use of water

6. Three sources
 Rain water
 Surface water
 Ground water

7.  Rain water is normally the purest form of
water.
 Its really distilled water , but it receives
impurities from the moment of condensation
and before reaching the earth surfaces
impurities and different gases dissolved in it
and causes acid rain, so the rain water is to
much harmful for human and animal health.

8.  Surface water include River ,
 small stream ,
 lakes ,ponds ,
 and some reservoirs .
 surface water directly exposed to pollution by
surface wash and carried waste.

10.  Wells
 Springs
 Etc

11. Advantages
 Its usually free from pathogenic organism
 It usually requires no purification
 Its supply is continuous
 Disadvantages
 It is high in mineral contents
 It requires pumping

12.  Water is polluted by dissolved gases and
suspended impurities
 and contaminated by human and animal waste
and pathogenic organism
Example :
 Dissolved gases ,impurities,
 fertilizers ,organisms ,chemicals and causes
water born diseases

13.  Clean water
 Polluted water
 Contaminated water

14.  Clean water are those water which are free
from contamination and safe for human
consumption as determined by laboratory
analysis , sanitary , and continued use,

15.  Polluted water are those which included
impurities and others substances which alter
the physical qualities of water and causing
turbidity and change the color , Oder ,and taste
due to,
 dissolved gases
 Industrial wastes
 Fertilizers
 sewage

16.  Contaminated water are those water which
included human and animal waste product and
also pathogenic organism in the form of
 Bacteria
 virus
 fungi etc

28.  These are due to the following factors.
 Excess of soluble salts
 the presence or absence of an element or
metals.
 insecticides
 Chemicals
 Radio active waste

diseases

31.  Diarrheal diseases
 Cholera
 Enteric fever
 Dysentery
 Rotaviruses
 Legionella

32.  Viral hepatitis A
 Hepatitis E
 Poliomyelitis
 Human adenovirus causing gastroenteritis
 Rotavirus causing GE in children under 4 years
of age.

33.  Amoebiasis
 Giardiasis
 Malaria
 Schistosomiasis
 Liver fluke

35.  Round worm
 Whip worm
 Hydated diseases

37.  Due to poor personal hygiene
 Scabies
 Conjunctivitis
 Trachoma
 Leprosy
 Others skin infection

38.  Caused by parasite that spend part of their life
cycle in water and produce larva.
 Mostly helminthic

39.  Vector water borne diseases are the following
 Dengue fever
 Malaria

40.  Water dispersed agent proliferate in fresh
water and enter the human body through
respiratory tract and cause disease example are
the following.
 Legionella
 Pneumonia
 cryptosporidium

42.  Government
 Communities
 individuals

43. Community level prevention
 Water borne epidemics and health hazard in
the aquatic environments are mainly due to
improper management of water resources
 The city water supply should be properly
checked and necessary step must be taken to
disinfect it
 Water pipe should be regularly checked for
leaks and cracks

44.  Avoid contacting soil that may be
contaminated with human feces.
 Don not defecate outdoors in open area.
 Dispose of diapers properly.
 Wash hand with soap and water before
handing.
 When traveling to another countries where
sanitation and hygiene are poor avoid water or
food my be contaminated

45.  At home the water should be
 boiled
 filtered
 to ensure that its free from infection
