New research sounds alarm on global water supply - Jay Famiglietti, senior water scientist at the NASA Jet Propulsion Laboratory, talks with Rachel Maddow about new research using satellites to detect underground water around the world and finding startling deficiencies in the global water supply.
NOTES ON WATER FILTRATION SOLUTIONS
News Report: BBC: 'Super sand' to help clean up dirty drinking waterContaminated water can be cleaned much more effectively using a novel, cheap material, say researchers.
Dubbed "super sand", it could become a low-cost way to purify water in the developing world.
The technology involves coating grains of sand in an oxide of a widely available material called graphite - commonly used as lead in pencils.
The team describes the work in the American Chemical Society journal Applied Materials and Interfaces.
In many countries around the world, access to clean drinking water and sanitation facilities is still limited.
The World Health Organization states that "just 60% of the population in Sub-Saharan African and 50% of the population in Oceania [islands in the tropical Pacific Ocean] use improved sources of drinking-water."
The graphite-coated sand grains might be a solution - especially as people have already used sand to purify water since ancient times.
There is an organization working on the current water crisis...

MICHAEL PRITCHARD'S WATER FILTER TURNS FILTHY WATER DRINKABLE
Too much of the world lacks access to clean drinking water. Engineer Michael Pritchard did something about it -- inventing the portable Lifesaver filter, which can make the most revolting water drinkable in seconds. An amazing demo from TEDGlobal 2009.

REVIVING NEW YORK'S RIVERS -- WITH OYSTERS!
Architect Kate Orff sees the oyster as an agent of urban change. Bundled into beds and sunk into city rivers, oysters slurp up pollution and make legendarily dirty waters clean -- thus driving even more innovation in "oyster-tecture." Orff shares her vision for an urban landscape that links nature and humanity for mutual benefit.

NED BRESLIN: FIXING THE WATER CRISIS
"Is water still running?" is perhaps the most important question for water initiatives worldwide, concludes Water for People CEO Ned Breslin. He's tired of seeing broken hand pumps and taps litter Africa, Asia, and Latin America. These signs of failed projects underscore the critical need to overhaul water aid for real impact.
