Far more of our freshwater is stored underground as groundwater than is in our lakes, rivers, and streams. Philippe Cousteau travels to the Orange County Water District in Fountain Valley, CA,to meet with engineer Sandy Scott Roberts, who explains how they manage and use the freshwater from this surprising underground source.

Looking at Earth from space, it definitely looks like a water planet. Although 71% of Earth is composed of water, freshwater is limited and must be managed. Philippe Cousteau meets with Kat Bormann from NASA’s Jet Propulsion Laboratory, and Marty Adams from the Los Angeles Department of Water and Power to learn how freshwater resources are being managed using innovative technological solutions.
