• ~1 billion people worldwide drink untreated surface water
• 2 million of this population (mostly children <5 yrs old) die from disease caused by contaminated water.

• Moringa oleifera is a vegetable tree commonly grown in the developing world.
• "One of the world's most useful trees"
• Drought resistant
• Provides oil for cooking & lighting
• Soil fertilizer
• Pods, leaves, seeds, & flowers are edible and highly nutritious
• *Simple, low-cost, natural water treatment uses seeds from the tree*
• Reduces water-borne bacteria by 90-99%
• Reduces water turbidity (cloudiness due to suspended debris) by 80-99.5%
• The most significant part of this is not the purification technique itself, but the public access granted by the researchers at Clearinghouse. http://www.currentprotocols.com/protocol/mc01g02
