Science Nation - Follow the Water

submitted by: nsf
Already parts of the world suffer from lack of water, and with increasing demand it's expected to get worse. To better understand and predict drought, 30 universities are collaborating in a multi-disciplinary effort called the Shale Hills Project. Among the studies, is field research following the life cycle of water along the Susquehanna River Basin, the main tributary to the Chesapeake Bay. With support from the National Science Foundation, civil engineer Chris Duffy and his team at Penn...

Whether it goes down drains, sewers or toilets, much of it ends up at a wastewater treatment plant where it undergoes rigorous cleaning before it flows back to the environment. The process takes time, money and a lot of energy. What if that wastewater could be turned into energy? It almost sounds too good to be true, but environmental engineer Bruce Logan is working on ways to make it happen. Most treatment plants already use...
