- Natural systems clean water
- Detecting lead in tap water
- Floating farms avoid salty water
- Nanogrid uses sunlight to clean up oil
New purification methods can make it possible to rely on untapped water sources, such as saltwater, and to provide clean water after a disaster. The next step: getting treated water safely into our taps.
Helpful bacteria are turning agricultural and oil-and-gas wastewater into clean water and energy, acoustic methods are shaking contaminants out, and engineered viruses are keeping harmful bacteria in check. The long-term future? Water treatment that’s compact, mobile and off the grid.
Why waste our water? Engineers envision a new cycle of water reuse, an urgent need where water is scarce. That means using greywater right where we make it, capturing stormwater and run-off, and understanding how contamination affects our waterways and homes.
Understanding the connections between water, food and energy helps researchers create sustainable ways to meet our needs for all three.
