Water, water everywhere. But only 0.3 percent of the world's water is fresh water on the surface and ready to drink. As a consequence, there's a huge and growing market for companies that can turn non-potable water into clean, drinkable, life-sustaining H20.

It's a business worth hundreds of billions of dollars. And it's something that Massachusetts excels at. Some 300 companies that deal in water technology are headquartered in our state.

Guests
