Driven by Climate Change, Desalination Researchers Seek Solutions to Water Scarcity

/in , , /by /Here and Now (WBUR, Boston)by Tonya Mosley and Samantha Raphelson

The state of California has dedicated $34 million for eight desalination facilities across the state amid growing concerns about water scarcity in the U.S.

Desalination is when saltwater is converted into freshwater. Though 71% of the Earth is made up of water, extreme weather linked to climate change is adding to concerns about water scarcity.

Scientists estimate that by 2071, nearly half of the 204 freshwater basins in the U.S. may not be able to meet the monthly demand for water, according to a study published in the journal Earth’s Future.

Extracting salt from water seems like an easy fix to a global problem, but the process of desalination can be expensive, and it can also have a huge impact on the environment. That’s why some researchers are looking into how to lower the cost and improve efficiency.

Desalination technology can cost anywhere between two to 10 times the cost of traditional freshwater sources, says Meagan Mauter, research director for the National Alliance for Water Innovation and an associate professor of civil and environmental engineering at Stanford University.

Trump’s Signature Could Mean More Water for Valley

/in , /by /GV Wire (Fresno, Calif.)by David Taub

More water will flow toward San Joaquin Valley farmers, President Donald Trump declared at an event in Bakersfield on Wednesday afternoon.

Trump announced the completion of biological opinions that will increase water allocations in Californians.

“A major obstacle to providing more water for the region’s farmers has now been totally eliminated by the government,” Trump said.

On Eve of Trump Visit, Critics Ask Why Newsom Hasn’t Fought President’s Water Moves

/in , , /by /San Francisco Chronicleby Kurtis Alexander

During President Trump’s visit to California this week, the commander in chief who campaigned on a pledge of shipping more water to Central Valley farms plans to stop in Bakersfield to boast about a promise kept.

His administration has succeeded in rolling back protections for fish in California, opening the door to more pumping from rivers and streams, and more irrigation deliveries for the state’s vast agricultural economy.

The endeavor is no surprise for a president who has been supportive of industry and hopes to rally rural voters behind his re-election bid. But what confounds some who are worried that Trump’s water plan could undermine the environment is how little the state has done to stop Washington.

Nearly Half the Country Working on PFAS Rules as EPA Drags Feet

More states are stepping up to protect people from drinking water contaminated with “forever chemicals” in the absence of federal enforcement.

Twenty-three states are writing their own guidance, regulations, or legislation that would address drinking water contaminated with per- and polyfluoroalkyl substances, also known as PFAS.

The family of thousands of chemicals, once used in Teflon and Scotchgard, may cause liver tissue damage, immune system or thyroid problems and increased cholesterol levels, according to the Environmental Protection Agency. The substances require massive amounts of energy to fully break down, enabling them to persist in the environment, seemingly “forever.”

Microplastics: A Macro Problem

/in , , /by /PHYS.orgby University of California, San Diego

Flying somewhere over the planet, there’s a plane equipped with research-grade, double-sided tape on the outside of its hull. Each time the pilot lands the plane, he removes the tape, seals it in a package, and replaces it with a new one before he takes off again. He then mails the package to Scripps Institution of Oceanography at UC San Diego, care of Dimitri Deheyn, Associate Researcher.

Looking at the tape under a microscope, Deheyn sees what he’s looking for: microfibers, stuck to the adhesives.

State Seek Input on Delta Tunnel Plan

/in , /by /The Pressby Tony Kukulich

The California Department of Water Resources is holding a public meeting in Brentwood, Thursday, Feb. 20 at the Brentwood Community Center from 6 – 8 p.m. to review the details of the Delta Conveyance Project

The Delta Conveyance Project is the latest iteration of the state’s plans to build a tunnel through the Delta that will convey water from the Delta’s northern reaches to a forebay near Byron. From there, water will move on to the Central Valley and Southern California through the existing State Water Project network of canals. Previously known as WaterFix, or the twin-tunnels project, Gov. Gavin Newsom reduced the project to a single tunnel last year, spurring the new initiative.

U.S. Infrastructure Needs Exceed $2 Trillion, American Society of Civil Engineers Says

/in , , /by /Transportation Today by Liz Carey

As public spending on infrastructure declines, America will underinvest in its infrastructure by an estimated more than $2 trillion between 2016-2025, a new report from the American Society of Civil Engineers says.

According to the American Society of Civil Engineers, public dollars spent on roads, bridges, water systems, and other infrastructure items fell by 8 percent between 2003 and 2017. And as the dollars spent on infrastructure fall, the damage to American pocketbooks increases.

See how Sparse the Sierra Nevada Snowpack Looks Compared to Last Year

/in , /by /The Mercury Newsby Paul Rogers

Two NASA satellite images released late Monday by the National Weather Service office in Sacramento starkly illustrate how much less snow is covering the Sierra Nevada this week compared to the same time a year ago.

The images, taken from roughly 438 miles above Earth, show California’s Sierra Nevada range. In the first, from Feb. 18, 2019, the region is blanketed with snow. On that day, the snowpack, which is the source of about one-third of the state’s annual water supply, was at 147% of its historical statewide average for that date.

New California Law Creates Pathway to Water Industry Jobs for Military Veterans

/in , , /by /Association of California Water Agencies (Sacramento)by Will Holbert Mentioned: San Diego County Water Authority

Legislation co-sponsored by the San Diego County Water Authority and the Otay Water District is intended to make it easier for military veterans to launch careers in the water industry.

After Lt. Jose Martinez retired from the U.S. Navy in 2007, he went from serving his country underwater to serving reliable, high quality water to a community. 

His experience aboard a nuclear submarine and on the management staff of Otay Water District shares a few commonalities. Both involve highly complex systems, which often operate away of the public eye, either underwater or underground. 

“People turn on the tap and out comes water,” said Martinez, General Manager for ACWA-member Otay Water District. “It seems rather simple, but it’s really complex. It’s fascinating to me.”

California Attorney General Becerra Says EPA’s Proposed Standards for Lead in Drinking Water Fails the Test Americans Expect

/in , /by /Sierra Sun Times

California Attorney General Xavier Becerra, leading a 10-state coalition, on Wednesday filed comments on the U.S. Environmental Protection Agency’s proposed amendments to nationwide standards for controlling and remediating lead in drinking water, also known as the Lead and Copper Rule. The EPA’s proposed revisions represent the first major amendments in a generation to the Lead and Copper Rule, which was first promulgated in 1991. Although some of the proposed revisions strengthen the 1991 rule, others weaken existing requirements and fail to adequately protect the public from lead in drinking water.
