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.

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.

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.

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.

Kern County Water Industry is Ready to Discuss Water Concerns with President Trump

/in , , /by /Bakersfield Now by Jeanette Quezada

Water is essential for survival.

It’s just as true for you and me as it is for the Ag community of Kern County, which depends on water to grow all of its crops.

According to Gene Lundquist, president of the Water Association of Kern County, we use more than two million acre-feet to grow what feeds the entire country.

“We cannot do anything here in Kern County without water,” he said.

Lundquist said most of the water we use is groundwater.

The second-largest source is the state water project water, which comes from the California aqueduct.

Toxic Waste Still a Problem for El Cajon Neighborhoods

/in , , /by /East County Californianby Albert Fulcher

From 1963 to 1985, aerospace manufacturing company Senior Aerospace Ketema (formerly Am­etek) in El Cajon dumped thousands of pounds of a chemical degreaser into a shallow redwood-lined pit that sat on its property.

This resulted in a toxic groundwater plume of trichloroethylene, which travels through the soil by a process called soil vapor intrusion into the three large mobile home parks surrounding the facility — Greenfield, Starlight and Villa Cajon — as well as Magnolia Elementary School.

This caused related illnesses among residents and students alike. The air in one mobile home at the school had more than twice the amount that triggered an immediate closure of Magnolia El­ementary in the 2015-16 school year due to health concerns. TCE is known to cause a variety of cancers, cause re­productive harm, damage the immune system, and can cause dizziness, headaches, and confusion.

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.”

City of Oceanside to Break Ground on Pure Water Oceanside

/in , , /by /Times of San Diegoby Debbie L. Sklar Mentioned: San Diego County Water Authority

Marking a historic moment for the city of Oceanside and the region, city officials and water industry leaders will break ground on Pure Water Oceanside on Wednesday, Feb. 19 at 10 a.m. at the San Luis Rey Water Reclamation Facility. Scheduled to be completed before the end of 2021, Pure Water Oceanside will be on the map as the first operating recycled water project in San Diego County.

Pure Water Oceanside will purify recycled water using state-of-the-art purification technology that replicates and accelerate nature’s natural recycling process to create a new local source of high-quality drinking water that is clean, safe, drought-proof and environmentally sound. Pure Water Oceanside will lead the way in the region in providing a sustainable water supply for its residents, businesses and visitors. Once finished, the project will provide more than 32% of the city of Oceanside’s water supply, or 3-5 million gallons per day.

At the groundbreaking, Congressman Mike Levin, City of Oceanside Water Utilities Director Cari Dale, San Diego County Water Authority General Manager Sandra Kerl, Bureau of Reclamation Area Manager Jack Simes and Metropolitan Water District Special Projects Manager Meena Westford will discuss the many benefits of the project – including reducing dependence on increasingly expensive imported water, safeguarding against drought and ensuring an exceptionally pure drinking water supply is available for future generations.
