A team of Purdue University researchers has invented a prototype water-disinfection system that could help the world's 800 million people who lack safe drinking water.
Scientists at Kansas State University and seven other collaborating institutions were recently awarded $3.3 million from the National Science Foundation to conduct a-large scale study of how stream organisms influence water quality across North America.

A proposed landfill near San Diego threatens a critical drinking water source, endangered species habitat and sacred Native American lands.
Virtual water – the amount of water it takes to produce goods or a service – has been suggested as a possible solution to this growing problem by using virtual water values to inform international trade deals. But researchers say that the existing amount of virtual water is not large enough to overcome the existing inequalities.
