‘Greywater’ Could Help Solve Colorado’s Water Problems. Why Aren’t We All Using It?

/in , , /by /CPR News by Michael Sakas

Your shower, sink and laundry machine account for more than half of indoor water use. Since the wastewater that circles the drain doesn’t come from the toilet, it’s safe to reuse on things like your garden.Those hip to reuse call it greywater. To state and local governments, it’s graywater. However you spell it, it’s an idea that everyone agrees will save water — but not everyone agrees on how it should be done.

Colorado was the last Western state to legalize greywater usage in 2013. Officials say that by 2050, our water supply could fall short for over one million people. Climate change makes the future of Colorado water even more uncertain.

OPINION: California Refuses To Enlist Clean, Cheap Hydropower In Fight Against Climate Change. It Makes No Sense

/in , , /by /CALmatters (Sacramento)by Adam Gray

Is the cleanest, greenest electricity in the world green enough for California? For years, the people of the Northern San Joaquin Valley have been trying to get hydropower recognized for what it is: the original source of clean electricity. Our efforts have been stymied by people who feel entitled to decide what is, or isn’t, green enough. That’s why I have begun the process of modifying our state Constitution to recognize safe, abundant, carbon-free hydropower as a reliable source of renewable energy in our fight against climate change. I have authored Assembly Constitutional Amendment 17 to place this question before California’s voters.

Ties Between The Delta And Groundwater Sustainability In California

/in , , /by /California Water Blogby Jay Lund

Groundwater overdraft is a major problem globally and has been a persistent and growing problem in California for decades. This overdraft is predominantly driven by the economic value of water for agricultural production and cities. Spurred by the recent drought, California passed legislation requiring the elimination of groundwater overdraft by 2040. To explore potential water supply effects of ending long-term groundwater overdraft in California’s Central Valley, we compared several water policies with historical and warmer–drier climates, employing a statewide hydroeconomic optimization model, CALVIN, in our new paper.

How 1,500 Nuclear-Powered Water Desalination Plants Could Save The World From Desertification

/in , , /by /Forbesby James Conca

About 20% of the world’s population has no access to safe drinking water, and this number will increase as the population continues to grow and global freshwater sources continue to decline. The worst-affected areas are the arid and semiarid regions of Asia, the Middle East and North Africa. UNESCO has reported that the freshwater shortfall worldwide will rise to 500 trillion gallons/yr by 2025. They expect water wars to break out in the near-future. The World Economic Forum says that shortage of fresh water may be the primary global threat in the next decade.

Climate Change Threatens California Freshwater Fish. We Can Do Something About It, Experts Say.

/in , /by /The Sacramento Beeby Caroline Ghisolfi

Fish die-offs in freshwater lakes are an increasing threat in California, and experts say climate change is to blame. Researchers from UC Davis and Reed College in Portland, Ore., found a strong link between fish deaths in freshwater lakes in Wisconsin and hot summers. They predict that fish die-offs will double by 2050 and quadruple by 2100 in Wisconsin. Andrew Rypel, a UC Davis wildlife, fish and conservation biology researcher, said we should expect similar effects in California. He told The Bee in an interview that California lakes may be even more vulnerable to the effects of climate change than those in Wisconsin, because they host many sensitive cold-water species.

Where’d The Beach Go? Lake Tahoe Fills To The Top As Massive Winter Snows Melt

/in , /by /Vallejo Times-Herald (Vallejo, Calif.)by Paul Rogers

If you visit Lake Tahoe this summer, the beaches might seem a little smaller than they were a few years ago. It’s not an optical illusion. Large sections of them really are underwater. Dozens of feet of snow that blanked the Sierra Nevada this winter, generated by blizzards from raging atmospheric river storms, have been steadily melting all spring and summer, sending billions of gallons of water rushing downhill and steadily raising the water level at Lake Tahoe.

Administration Sidelines Federal Biologists Who Could Stand In Way Of More Water For Calif. Farmers

/in , /by /KQED (San Francisco)by Lauren Sommer

After rushing forward on a plan to send more water to California’s Central Valley, the Trump Administration has unexpectedly hit the brakes and ordered the work already done by federal scientists to be completed by a different team. Just days before federal biologists were set to release new rules governing the future of endangered salmon and drinking water for two-thirds of Californians, the administration replaced them with an almost entirely new group of lawyers, administrators and biologists to “refine” and “improve” the rules, according to an email obtained by KQED.

California Legislators Halt Cadiz Water Project, Bill Heads To Gov. Newsom’s Desk

/in , , /by /Palm Springs Desert Sunby Janet Wilson and Sam Metz

The Cadiz groundwater pumping project in the Mojave Desert hit a major roadblock on Thursday, when the California State Assembly advanced a bill that could halt its progress for up to two years. If the bill becomes law, Cadiz, Inc.’s proposed project will need to undergo additional environmental review to prove its extraction plans will not harm the surrounding desert. S.B. 307, authored by Sen. Richard Roth, D-Riverside, cleared the Assembly 49-23, where it was led by Assemblywoman Laura Friedman, D-Glendale, who carried similar Cadiz-related legislation in 2017 and 2018 that stalled before final votes. After years of legislative battles and intense lobbying, the bill now only needs Gov. Gavin Newsom’s signature to become law.

California’s Coast Is Disappearing, And The Debate Over What To Do About It Is In Full Swing

/in , /by /Los Angeles Timesby Diya Chacko

Even as quakes, wildfires and drought have taken up most of our focus, the slow-moving disaster of rising seas has paralyzed Californians, and left us with “both too much and not enough time” to act, as environment reporter Rosanna Xia wrote in a special report examining sea level rise and the future of California’s disappearing coastline. The report, read by more than half a million people since it was published online and in print on Sunday, laid out our limited options in a future where certain areas of California will almost certainly be submerged. Cities such as San Francisco, Pacifica, Imperial Beach and many more are already dealing with the ocean at their doorstep.

The Fight Over Monterey Peninsula’s Water Future is a Debate Over Who Gets To Decide

/in , , /by /Monterey County Weeklyby Asaf Shalev

What is at stake is the water supply for the Monterey Peninsula. Consuming water drawn from the Carmel River is no longer feasible, neither ecologically nor legally. But the power to decide on an alternative supply is largely vested in the hands of public officials from outside the region.
