Desalination — Can It Help Us Survive Water Scarcity?

From Ancient Greek sailors boiling seawater to Romans using clay pipes to filter salt, making saltwater drinkable through desalination has a long history. But modern forms of this millennia-old technology are now the “present and future of coping with water scarcity,” said Manzoor Qadir, deputy director of the United Nations University Institute for Water, Environment and Health.

As the Colorado River Declines, Water Scarcity and the Hunt for New Sources Drive Up Rates

The price of water is rising across the Southwest as utilities look to cover the cost of the increasingly scarce resource, the infrastructure to treat and distribute it and the search for new supplies.

Opinion: Water is Precious in the American West. California Barely Even Tries to Manage it

For eight days last summer, a group of about 80 California ranchers and farmers took more than half the Shasta River’s flow during severe drought conditions, violating state requirements designed to protect salmon. The state’s water regulator couldn’t stop the illegal diversion but fined the group the maximum penalty it could — $4,000. The fine translated to about $50 per person.

Opinion: The West’s Weather Whiplash Should Not Influence Long-Term Water Management

There’s a water contradiction in the West with serious long-term water scarcity in low reservoirs and depleting groundwater tables, while California is in the middle of an extremely wet and snowy winter. As water levels in dangerously depleted Lake Mead and Lake Powell drop to record lows, California has experienced one of the wettest winters on record, with a statewide snowpack that’s almost 200 percent of normal for this time of year and a flooding risks from rain and snow events in March.

Researchers Propose New Structures to Harvest Untapped Source of Freshwater

An almost limitless supply of fresh water exists in the form of water vapor above Earth’s oceans, yet remains untapped, researchers said. A new study from the University of Illinois Urbana-Champaign is the first to suggest an investment in new infrastructure capable of harvesting oceanic water vapor as a solution to limited supplies of fresh water in various locations around the world.

Punishing Bay Area Drought Prompts Calls for Major Water Rethink

Each morning for months, Amelia Morán Ceja has peered out her window, searching Sonoma’s wine country for dark clouds or the residue of rain on the leaves of her grapevines.

Her searching has proved futile, and now she’s worried as California faces its third consecutive summer with drought.

The dry conditions threaten her thirsty vines at Ceja Vineyards and elevate the risk from fire and heat waves. The triple threat is a “perfect storm during harvest,” she said.

Newsom Calls for More Aggressive Water Conservation Amid Third Year of Drought

On the heels of the driest ever start to the year in California, Gov. Gavin Newsom on Monday issued a sweeping executive order calling on local water suppliers to implement more aggressive conservation measures as reservoirs dwindle and residents backslide in their efforts to cut back.

Specifically, the order requires that urban water suppliers activate “Level 2″ of their locally customized contingency plans, meaning they must prepare for a shortage of up to 20%.

California Ballot Measure to Build More Reservoirs, Water Projects Dies Due to Lack of Signatures

Supporters of a proposed November ballot measure to provide billions of dollars to build new dams, desalination plants and other large water projects in California announced Tuesday they are ending their campaign due to lack of signatures and funding.

“Despite crafting an initiative that would solve California’s challenge of chronic and worsening water scarcity, and despite recent polling that indicates over 70% of California’s voters support increased state spending on water infrastructure, the campaign has been unable to attract the financial support necessary to gather the required 1 million signatures,” the campaign said in a statement.

The West is the Driest it’s Been in 1,200 Years – Raising Questions About a Livable Future

Trees are dying. Riverbeds are empty. Lake Mead’s water level dropped to its lowest point in history, and Utah’s governor asked residents to pray for rain. Water is increasingly scarce in the Western U.S. — where 72 percent of the region is in “severe” drought, 26 percent is in exceptional drought, and populations are booming. Insufficient monsoon rains last summer and low snowpacks over the winter left states like Arizona, Utah and Nevada without the typical amount of water they need, and forecasts for the rainy summer season don’t show promise.

When Water is Scarce, Some Researchers Go Underground to Find Out Why

When it comes to water in the West, a lot of it is visible. Snow stacks up high in the mountains then eventually melts and flows down into valleys. It’s easy to see how heavy rains and rushing rivers translate into an abundance of available water. But another important factor of water availability is much harder to see. Beneath the surface, the amount of moisture held in the ground can play a big role in how much water makes it down to rivers and reservoirs – and eventually into the pipes that feed homes and businesses.
