Nearly 1 billion people lack access to safe water supplies;
approximately one in eight people. (3)
2.5 billion people lack access to improved sanitation, including 1.2
billion people who have no facilities at all. (3)
3.575 million people die each year from water-related disease. (4)
The water and sanitation crisis claims more lives through disease
than any war claims through guns. (1)
An American taking a five-minute shower uses more water than a
typical person in a developing country slum uses in a whole day. (1)
Diarrhea remains in the second leading cause of death among
children under five globally. Nearly one in five child deaths – about
1.5 million each year – is due to diarrhea. It kills more young
children than AIDS, malaria and measles combined. (5)
Every 20 seconds, a child dies from a water-related disease. (2)
A 2006 United Nations report focuses on
issues of governance as the core of the
water crisis,
 "There is enough water for everyone”
 "Water insufficiency is often due to
mismanagement, corruption, lack of
appropriate institutions, bureaucratic
inertia and a shortage of investment in
both human capacity and physical
infrastructure"

Population Increases:
 As populations grow, industrial, agricultural and individual
water demands escalate.
 World-wide demand for water is doubling every 21 years
Greater water usage:
 Associated with rising standards of living (e.g., diets
containing less grain and more meat)
 Reflects potentially unsustainable levels of irrigated
agriculture
Desertification (in many countries)
Deteriorating water quality:
 population increases and salinity caused by industrial
farming and over-extraction rises.
 About 95 percent of the world's cities still dump raw sewage
into their waters
Water Usage
Developed vs. Developing Countries
•The term
developed country
is used to describe
countries that have
a high level of
development
according to some
criteria (usually
economic).
•A child born in the
developed world
uses 30 to 50 times
as much water as
one in the
developing world
Advanced economies
Emerging and developing economies (not least developed)
Emerging and developing economies (least developed)
Classifications by the IMF and the UN

Constituents in water:
 Disease vectors (an insect or any living carrier that
transmits an infectious agent)
 Pathogens (e.g. Giardia and Cryptosporidium)
 Dissolved Chemicals
 Suspended Solids
