The World Bank estimated in 2016 it would take $1.7 trillion USD to achieve universal access to clean water and sanitation by 2030. By other estimates that amount is now even higher.    Gary White is the CEO and Co-founder, along with Matt Damon, of Water.org and WaterEquity. The two also co-wrote the book The Worth of Water: Our Story of Chasing Solutions to the World's Greatest Challenge.   White joins host Jay Famiglietti to discuss the inspiration behind his organization, the financial plumbing it will take from investors, and how women around the world are pivotal in solving the global water crisis.   We conclude the episode by hearing Matt Damon describe his interest in water and why it has become a personal issue for him.
