Here's a fun science piece from NPR's "sciency blog":

It begins:

"Water feels good when we're thirsty, cools us when we're hot, looks great in a pond, a lake, a cloud. Because we ourselves are two-thirds water, we like the stuff, we're drawn to it. We search the universe looking for signs of water and when we look back at our planet, we are small and pale, yes, but we're dazzlingly blue.

On June 16, the Rodale Institute will hold a ribbon-cutting ceremony to celebrate the opening of its new Water Purification Eco-Center located on its research farm in Kutztown, Penn. The center, supported in part through a $695,000 grant from the U.S. Environmental Protection Agency (EPA), will serve as a model on-site wastewater treatment system.  The system incorporates an experimental wetland-based treatment and reuse facility that captures rainwater and reuses it several times before returning it to the soil as clean water.
