No new water
By 2025 2/3 of the World's population will suffer
CONTAMINATED WATER
Water Contamination causes:
Diarrhea:
causes person to lose water electrolytes leads to dehydration
Cholera:
causes severe attacks of diarrhea
Typhoid Fever:
causes headaches and nasea
Arseniscosis:
caused by consuming water contaminated with arsenic
Flourosis:
bone disease caused by consuming water contaminated with high concentrations of flouride
Guinea Worm Disease:
causes debilitating ulcers
Schistosomiasis:
damages the liver, intestines, lungs and bladder.
Trachoma:
causes eye infection and can lead to blindness
Cholera
Arseniscosis
Guinea Worm Disease
Schistosamiasis
Trachoma
1800s
outbreaks of typhoid and cholera in the US and GB
believed cholera was spread through air, not water
John Snow
1854: discovered that cholera was spread through water
People became more cautious of water they consumed
Lead to improved treatments in sewage farming, chemical precipitation, filtration, sedimentation, chemical treatment and activated sludge treatment
Water Scarcity:
Diseases
Malnutrition/dehydration
children have to walk to miles just to gather enough water for one day- cannot attend school
United Nations Millennium Development Goals (MDG)
"by 2015, halve the proportion of the population without sustainable access to safe drinking water and basic sanitation"
Innovations for Poverty Actions (IPA)
The Water Project
Global Water
Organizations
Creating Easy Access to Water
The Water Project and Global Water organizations builds wells and boreholes in developing countries
Sanitizing and Purifying Water
IPA is using chlorine dipensers to disinfect water
Chlorine dispensers kill large variety of waterborne pathogens that can cause typhoid fever & Cholera
Provides disinfected water to:
24,000 students
2,200 households
Vestergaard Frandsens LifeStraw and LifeStraw Family
A portable water filter for the prevention of common diarrheal diseases
"not enough to treat water at the point-of-source, it must also be treated at the point-of-consumption"
181 million in the last fourteen years
884 million more to go
Most Americans have easy access to clean water
often consider public drinking fountains "unclean"
On average, Americans use between 100 and 175 gallons of water everyday, just at home
Water is also wasted:
It takes 1.85 gallons of water to produce one plastic water bottle
Irrigation systems account for 70% of water used: over half of this water leaks, evaporates, or allows runoff
Predictions:
By 2013, 36 states will suffer from water shortages
By 2025, two thirds of the world's population will suffer from water shortages
Desalination Plants
Purpose: turn salt water into clean drinking water
-more than $100 million
Should governments spend this much money on desalination plants, or on purifying, sanitizing, and providing access to the water we already have?
BETTER: many people working to help others obtain easy access to clean water

WORSE: many people who already have easy access to water take it for granted and carelessly waste it
