California’s Water Supplies Are in Trouble as Climate Change Worsens Natural Dry Spells, Especially in the Sierra Nevada
California is preparing for a third straight year of drought, and officials are tightening limits on water use to levels never seen so early in the water year. Especially worrying is the outlook for the Sierra Nevada, the long mountain chain that runs through the eastern part of the state. California’s cities and its farms – which grow over a third of the nation’s vegetables and two-thirds of its fruit and nuts – rely on runoff from the mountains’ snowpack for water.

Groundwater in California’s Central Valley May Be Unable to Recover from Past and Future Droughts
Groundwater in California’s Central Valley is at risk of being depleted by pumping too much water during and after droughts. Water resources could be pushed beyond recovery in a region that provides about a quarter of the U.S. food supply.

Using AI to Provide the World with Drinking Water
Though water covers 71 percent of earth’s surface, more than 2.5 billion people in the world lack access to fresh water at least once a month. Researchers are seeking new possibilities in water purification through using AI agents in the desalination process.

Groundwater Flow to Colorado River May Decline by a Third over Next 30 Years
A new study projects that a hot and dry future climate may lead to a 29 percent decline in Upper Colorado River Basin “baseflow” at the basin outlet by the 2050s, affecting both people and ecosystems. Baseflow is the movement of groundwater into streams and, on average, accounts for more than 50 percent of annual streamflow in the Upper Colorado River Basin.

Managing Water Resources in a Low-to-No-Snow Future
With mountain snowpacks shrinking in the western U.S., a new Lab study analyzes when a low-to-no-snow future might arrive and implications for water management.

Making Desalinated Water Safer, Cheaper
Approximately 80 percent of drinking water in Israel is desalinated water, coming from the Mediterranean Sea. Israeli scientists and colleagues develop an effective and low-cost way to remove toxic boron from water in the process of desalination.

Nuclear Physics Used to probe Floridan Aquifer Threatened by Climate Change
Florida is known for water. Between its beaches, swamps, storms and humidity, the state is soaked. And below its entire surface lies the largest freshwater aquifer in the nation. As rising sea levels threaten coastal areas, scientists are using an emerging nuclear dating technique to track the ins and outs of water flow.

Avoiding Water Bankruptcy in the Drought-Troubled Southwest: What the U.S. and Iran Can Learn from Each Other
In August, the U.S. government issued its first ever water shortage declaration for the Colorado River, triggering water use restrictions. The fundamental problem is the unchecked growth of water consumption. The Southwest is in an “anthropogenic drought” created by the combination of natural water variability, climate change and human activities that continuously widen the water supply-demand gap.

Lowering the High Cost of Desalination
Removing salt and other impurities from sea-, ground- and wastewater could solve the world’s looming freshwater crisis. A suite of analytical tools makes it easier for innovators to identify promising research directions in making saltwater potable.

Changing Climate Increases Need for Water Diplomacy
The dispute between Ethiopia and its neighbors over the massive Renaissance Dam on the Blue Nile is but one example of how the climate change-driven growing scarcity of water may soon lead countries to engage in what, a decade ago, British intelligence called “water wars.” These growing tensions need to be tackled in new ways.

Calif.’s Central Valley: Increased Pumping During Drought in Worsens Groundwater Quality
Researchers, examining thirty years of data from California’s Central Valley, found that intensive pumping of aquifers during drought can speed up deterioration of groundwater quality.

Iran-Afghanistan Water Dispute: A Test of Tehran's Ties to Taliban
An old dispute over water rights could be the first test of Iran’s planned pragmatic cooperation with the Taliban. Without a functioning environmental agency, though, it is unclear who in Afghanistan can address the conflict.

River Backwaters and High Water Quality Standards
Clean drinking water is essential. Scientists are investigating how water quality in riverine floodplains, often used as drinking water resources, changes as a result of heavy rainfall and flooding.

As Western U.S. Is Experiencing a 1,000 Year Drought, Desalination Could Be a Solution
The Western United States is currently experiencing what one paleoclimatologist called “potentially the worst drought in 1,200 years.” The region has had many droughts in the past, including “megadroughts” that last decades, but climate change is making dry years drier and wet years wetter. One possible solution is the desalination of seawater, but is it a silver bullet?

Tracking Water Storage: Improving Water Management During Floods, Droughts
Researchers have created a balance sheet for water across the United States – tracking total water storage in 14 of the country’s major aquifers over 15 years. With longer-term droughts and intermittent intense flooding expected in the future, particularly in the arid western U.S., there is rising concern about overtaxing water resources in the region, especially for irrigated agriculture.
