“The book. . . might well guide some very satisfactory investments. . . Mr. Hoffmann does an able job of laying out the basics of water scarcity and delivery, and he presents a persuasive case for water's looming importance, rivaling oil as the most important commodity this century. . . A strong current of the investing advice in "Planet Water" is Mr. Hoffmann's contention that water utilities will move toward privatization and away from government management. Private management will make companies concentrate on core competencies to keep efficiencies high; those companies are the ones for investors to pursue.”--Wall Street Journal, 5/27/2009
