    The National Alliance for Water Innovation (NAWI), which is led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), has been awarded a five-year, $100-million Energy-Water Desalination Hub by DOE (pending appropriations) to address water security issues in the United States.

    In recent years, wildfires in the western United States have occurred with increasing frequency and scale. Climate change scenarios in California predict prolonged periods of drought with potential for conditions even more amenable to wildfires. The Sierra Nevada Mountains provide up to 70 percent of the state’s water resources, yet there is little known on how wildfires will impact water resources in the future.

  • Perspective: Water woes

    Florida has the largest concentration of freshwater springs in the world, but they are being devastated by increasing pollution and drastic declines in water flow. Some springs have dried up from overextraction; others have shown signs of saltwater intrusion and harmful algae blooms. The answer to this problem is simple: No more extraction permits should be granted, and existing permits should be reduced with the goal of eliminating bottled water production entirely in Florida. But that simple solution is not being implemented. In the next few months, Nestlé, the largest bottled-water company in the world, is set to renew its permit at Ginnie Springs, one of the most popular recreational attractions along the Santa Fe River,” Sainato and Skojec write. “The permit allows Nestlé to take one million gallons per day at no cost, with just a one-time $115 application fee.”

    Everyone remembers the scene in Chinatown when Jack Nicholson almost gets his nose sliced off, but many do not recall what the dispute was about. It wasn’t drug smuggling or gun running that got Nicholson’s character slashed. It was water rights. Since the film was released in 1974, the question of who will get the limited water in the American West, particularly the all-important flow of the Colorado River, has grown even more contentious. Dystopian novels and movies predict a future in which people fight it out for every last drop of water to quench the thirst of expanding cities, parched agriculture, and wasteful suburban grass lawns. But the future is already here.

    An experiment with a water-saving “smart” faucet shows potential for reducing water use. The catch? Unbeknownst to study participants, the faucet’s smarts came from its human controller. “We looked at the faucet because that’s where a lot of water usage in the home occurs, but when you compare your sink to other products in the house – a thermostat or refrigerator – you see that there haven’t been updates to how the sink works in a very long time,” says one researcher.

  • Food security

    Coasts, oceans, ecosystems, weather and human health all face impacts from climate change, and now valuable soils may also be affected. Climate change may reduce the ability of soils to absorb water in many parts of the world, according to a Rutgers-led study. And that could have serious implications for groundwater supplies, food production and security, stormwater runoff, biodiversity and ecosystems.

    Plastics in our waste streams are breaking down into tiny particles, causing potentially catastrophic consequences for human health and our aquatic systems. Approximately 300 million tons of plastic are produced globally each year and up to 13 million tons of that is released into rivers and oceans, contributing to approximately 250 million tons of plastic by 2025. Since plastic materials are not generally degradable through weathering or ageing, this accumulation of plastic pollution in the aquatic environment creates a major health concern.

  • Water security

    As populations boom and chronic droughts persist, coastal cities like Carlsbad in Southern California have increasingly turned to ocean desalination to supplement a dwindling fresh water supply. Promising design rules for cost-effective desalination rely on just a few ingredients: ionic liquids plus low-cost geothermal or solar heat, or waste heat from machines.

    Earlier this summer, the sixth-largest city in India, Chennai, ran out of water. Water crises are now global. Cape Town, South Africa, narrowly escaped Day Zero last year, but it’s still at risk, as are Sao Paulo and Mexico City. Iraq, Morocco and Spain also face water shortages.What we are seeing in Chennai right now is a devastating illustration of human-driven climate disruption,” says an expert. “It is hard for me to picture a near future where access to clean, fresh water continues in as plentiful a way as it is in most of our country at this moment.”

  • Floods

    Dependable, detailed inundation estimates are vital for emergency managers to have enough situational awareness to quickly get the right resources and information to flood-impacted communities. In 2007, severe flooding in southeastern Kansas put a spotlight on the lack of timely, reliable projections for floodwater spread.

    In a world of smart watches, smart homes and smart appliances that monitor their environments to keep users safe and informed, can whole cities be smarter? Short answer: Probably, using cutting-edge information technologies to keep citizens and property safer.

    With new rules coming into effect, California farmers and municipalities using groundwater must either find more water to support the aquifers or take cropland out of use. To ease the pain, engineers are looking to harness an unconventional and unwieldy source of water: the torrential storms that sometimes blast across the Pacific Ocean and soak California.

    Ping! The popular 1990 film, The Hunt for Red October, helped introduce sonar technology on submarines to pop culture. Now, nearly thirty years later, a team of scientists is using this same sonar technology as inspiration to develop a rapid, inexpensive way to determine whether the drinking water is safe to consume.

    It’s been a long time coming for desalination—desal for short. For decades, we have been told it would one day turn oceans of salt water into fresh and quench the world’s thirst. But progress has been slow. Jim Robbins writes in Wired that that is now changing, as desalination is coming into play in many places around the world. Several factors are converging to bring new plants on line. Population has boomed in many water-stressed places, including parts of China, India, South Africa, and the United States, especially in Arizona and California. In addition, drought—some of it driven by a changing climate—is occurring in many regions that not that long ago thought their supplies were ample.

    Almost one billion people depend on melt-water from Himalayan glaciers for the water they need, but global warming has dramatically increased the pace of glacier melting. A new analysis, spanning forty years of satellite observations across India, China, Nepal and Bhutan, indicates that glaciers have been losing the equivalent of more than a vertical foot and half of ice each year since 2000 — double the amount of melting that took place from 1975 to 2000.

    Groundwater recharging – that is, actively moving water underground, a practice known as managed aquifer recharge (MAR) — is the latest wave in water security. There are about 1,200 managed aquifer recharge projects in 62 countries. MAR can be used to restore depleted aquifers, rehabilitate ecosystems and cleanse polluted water. But there are challenges as well.

    Most Americans take clean drinking water for granted as a convenience of modern life. The United States has one of the world’s safest drinking water supplies, but new challenges constantly emerge. As a scientist specializing in water quality, I believe water providers and regulators can’t afford to be complacent.

    Concentrations of antibiotics found in some of the world’s rivers exceed “safe” levels by up to 300 times, the first ever global study has discovered. Researchers looked for 14 commonly used antibiotics in rivers in 72 countries across six continents and found antibiotics at 65 percent of the sites monitored.

    When you get a drink of water from your fridge or sink, do you think about where that water came from? A new study takes a national look at whether coal-fired power plants are unintentionally affecting drinking water treatment plants.

    Climate change is increasing the risk of water shortages across Europe, but researchers in the Netherlands are hoping to ease pressure by generating a steady supply of clean water and heat from deep underground reservoirs known as aquifers.
