Potable: water suitable for drinking.
According to WHO, over

of the global disease burden can be prevented by improving water supply, sanitation, and hygiene.
783 million people ( 1 in 6 people or 11% of the world's population) do not have access to safe, clean drinking water.


What is Potable Water?
The U.S. has the safest supply of

public

drinking water .
286 million people have access to safe drinking water.
The EPA regulates drinking water in the U.S.
The U.S has the greatest per capita water usage than
anywhere else in the world.

Potable Water in the U.S.
Potable Water in Africa
780 million people are without access to clean water in Africa.
3.4 million people
die each year from a water related disease. This is equivalent to the population of Los Angeles.
1 out of every 5 deaths
in children
under the age of 5
is due to a water-related disease.
According to the UN, Sub-Saharan Africa loses
40 billion hours
per year collecting water; this is the same as a whole year's worth of labor by France's entire labor force.
400 million people in Asia
lack access to clean drinking water.
1.8 billion people lack access to basic sanitation.
2/3 of the population in Asia and the Pacific have improved sanitation facilities; however, 1.21 billion people still
practice open defecation
.
the majority of open defecation occurs in India. 626 million people practice open defecation.
Potable Water in Asia
How much potable water is available?
97.5% of all water on earth is salt water. 2.5% of water is fresh water.
Of the 2.5% of
fresh water
, 70% is
frozen
.
Less than 1% of the world's fresh water is
accessible
and
affordable
.
Main Contaminants of Water

in Africa
Waste & Pollution
Insects
Cholera
Guinea Worm
Intestinal worms
Typhoid
Diarrhea
(number one killer)
Malaria
Yellow Fever
Dengue
Potable Water in Europe

Water scarcity due to droughts has affected at least 11% of Europe's population.
17% of Europe's land has been affected by
droughts
.
500 million Europeans are at risk for water scarcity.
According to WHO,
9 million people
across Europe do not have access to an adequately protected source of drinking-water (a so-called “improved” source), and about
100 million people
do not have access to piped water on premises.
Main Contaminants of Water in Asia
Arsenic poisoning: found in accessible groundwater that
28-35 million people
are exposed to. Prevalent in China & Bangladesh.
Japanese Encephalitis: brain swelling from bites caused by mosquitoes who have drunk contaminated water.
Methods of Water Collection in Developing Countries
wells
water pumps
jerry cans (large cans that weigh 40 pounds when full): members of communities walk an average of
6 kilometers
in developing countries to collect water.
directly from rivers & other natural water sources.
Ways to Combat These Issues
Educate populations
Lifestraw
SteriPEN
The Water Project
The World Water Day Project, through the Right to Play International Charity
chlorine tablets, ceramic filters, and solar disinfection
Between 1990 and 2010,
2 billion people
gained access to improved sources of drinking water
