Hurtado wants feds to probe hedge funds’ acquisition of water rights

State Sen. Melissa Hurtado (D-Bakersfield) and state Sen. Dave Cortese (D-San Jose) are calling for U. S. Attorney General Merrick Garland to investigate possible drought profiteering and water rights abuses in the western states.  “As the West grapples with historic drought, California farmers and water managers are struggling to find the water we need to survive.  We must be able to determine how anti-competitive practices and corporate investors may be disrupting water rights – leading to potential water shortages, water theft, and skyrocketing water rates,” Hurtado said in a news release Wednesday. … ” Continue reading at GV Wire here: Hurtado wants feds to probe hedge funds’ acquisition of water rights

The West, reliant on hydro, may miss it during heat waves

When California suffers a heat wave, it leans heavily on hydropower from the Pacific Northwest to keep the lights on.  But that hydropower may not always be available when it’s most needed, as climate change is shifting the ground on which the West’s dams sit. Higher temperatures means snowmelt occurs earlier in the year and leaves less water available for power generation during the depths of summer. The result is a heightened risk of blackouts during extreme heat waves as a result of less hydro availability, according to a report out this week from the North American Electric Reliability Corp. (NERC).  The report highlights a paradox of running the region’s electric grid in a warming world: As energy demand rises with temperatures, there may be less hydro available to supply power, increasing the need for fossil fuels. … ”  Read more from E&E News here: The West, reliant on hydro, may miss it during heat waves

USGS scientists explain how aquifer compaction is measured

A recent tour of California’s Central Valley given by the nonprofit organization Water Education Foundation included a stop at the USGS California Water Science Center’s extensometer near Porterville.  Tour participants, made up of water industry professionals, were met by USGS groundwater scientists Michelle Sneed and Justin Brandt who showed the extensometer to the group. The extensometer is one of several that dot the Central Valley. Extensometers measure compaction and expansion of an aquifer system, providing depth-specific data that can help scientists better understand the rate, extent, and at what depths in the system land subsidence is occurring. ... ”  Read more from the USGS here:  USGS scientists explain how aquifer compaction is measured

To pre-rinse or not to pre-rinse? How to use your dishwasher during the drought

The science is in. Dishwashers save water — especially if you run them only when you have a full load.  Experts will also tell you that you don’t even need to pre-rinse the crusty, sticky residue off your dishes before depositing them in the dishwasher. Just scrape the solid food off.  That saves even more water.  But for some who grew up not having a dishwasher, using the dishwasher mainly as a dish rack, or pre-rinsing the dishes before putting them in the machine (a ritual of up to 80% of dishwasher owners, estimated Wirecutter), ingrained dish-washing habits die hard. … ”  Read more from the LA Times here: To pre-rinse or not to pre-rinse?

California to test solar panels over irrigation canals to save water, boost electricity output

As the most persistent drought conditions on record continue to grip the Southwest, a pilot project in California’s lush Central Valley looks to save water and increase energy efficiency.  The Turlock Irrigation District, the California Department of Water Resources and university researchers are working together to build solar-panel canopies over existing canals to test and study the benefits for saving energy and water. They’ll break ground this fall on Project Nexus, which focuses on three sections of the district’s 250 miles of canals.  The district says canal water should cool the solar panels, increasing their efficiency, while the canopies will shade the water and protect it from wind, lowering evaporation while reducing aquatic growth that harms water quality. … ”  Read more from Cronkite News here: California to test solar panels over irrigation canals to save water, boost electricity output

Summer outlook: Most of US will see above-average temperatures as Western drought continues

The National Oceanic and Atmospheric Administration’s forecast for summer calls for a whole lot of heat without much rain to provide relief.  Nearly the entire contiguous US is expected to have above-normal temperatures this summer, which runs from June through August, according to Thursday’s Climate Prediction Center’s outlook. The combination of hotter weather and below-average rainfall is expected to fuel the megadrought that covers much of the West.  The chance for above-normal temperatures will continue to be an issue from the Inter-Mountain West to the Southern Plains, with an emphasis on the Desert Southwest.

President Biden forest plan stirs dispute over what counts as “old” and “mature”

President Joe Biden’s order to protect the nation’s oldest forests against climate change, wildfires and other problems devastating vast woodlands is raising a simple yet vexing question: When does a forest grow old?  Millions of acres are potentially on the line — federal land that could eventually get new protections or remain open to logging as the administration decides which trees to count under Biden’s order covering “old growth” and “mature” forests. Underlining the urgency of the issue are wildfires in California that killed thousands of giant sequoias in recent years.  Experts say there’s no simple formula to determine what’s old: Growth rates among different tree types vary greatly — and even within species, depending on their access to water and sunlight and soil conditions. … ”  Read more from the Monterey Herald here: President Biden forest plan stirs dispute over what counts as “old” and “mature”

The abundance choice, part 5: California’s fractured farmers

Edward Ring, a contributing editor and senior fellow with the California Policy Center, writes, “This statement, which I heard with my own ears sometime in early September of 2021, was made by someone painfully aware of the paradox it expressed. It epitomizes how California’s farmers confront the existential threat of not enough water to irrigate their crops. They are bitterly divided over what solutions to support. If your farm is located north of the Sacramento Delta, you don’t want Southern Californians to build a giant straw that will suck the North Central Valley dry. And if your farm is south of the Delta, escalating restrictions on pumping water into southbound aqueducts from fragile Delta ecosystems makes a tunnel an elegant solution.  Disagreement over how to transport water through, around, or under the Delta is just one of many causes of gridlock in California over water policy, but the scale of the project and the impact it would have makes it central to discussions over state water priorities. … ”  Read more from the California Globe here: The abundance choice, part 5: California’s fractured farmers

Lake Tahoe to the Delta: Sacramento region plans 750-mile trail network

As the Sacramento area’s freeways become more congested and suburban sprawl covers formerly open space, regional planners are focusing on alternate ways of moving people around. After three years of planning and community surveys, the region’s chief planning agency will announce in a series of public events today the framework of an extensive trail network that will serve nearly every corner of the six-county region. The Sacramento Region Parks and Trails plan would run from the shores of Lake Tahoe to the Delta. It would serve the Sierra foothills of El Dorado County, the rural farmlands of Yolo County and reach as far north as New Bullards Bar Reservoir in Yuba County. And it would transform a puzzle of disconnected trails into a 750-mile network. … ”  Read more from the Sacramento Bee here: Lake Tahoe to the Delta: Sacramento region plans 750-mile trail network

Santa Cruz: How CA coastal communities are working to conserve water, combat saltwater intrusion amid drought

For Executive Pastor Mark Spurlock, expanding classroom space at the Twin Lakes Christian School in Aptos has been addition by subtraction. At least when it comes to saving water.  Following development offset rules outlined by the Soquel Creek Water District, the school engineered water-saving solutions to offset the new space they were building including replacing lawn areas with a drought-friendly plaza that catches and diverts water routed from nearby rooftops.  “Underneath it is actually a water retention basin that takes stormwater and puts it back into the ground. And we also replaced every plumbing fixture on the campus with more high-efficiency fixtures. And so the combination of all of those measures amounted to 2 million gallons of water that would have otherwise gone down the drain,” Spurlock said. ... ”  Read more from ABC 7 here:  How CA coastal communities are working to conserve water, combat saltwater intrusion amid drought

PFAS chemicals do not last forever:The use of sulfite and iodide under ultraviolet light can destroy PFAS in water in a few hours

Once dubbed “forever chemicals,” per-and polyfluoroalkyl substances, or PFAS, might be in the market for a new nickname.  That’s because adding iodide to a water treatment reactor that uses ultraviolet (UV) light and sulfite destroys up to 90% of carbon-fluorine atoms in PFAS forever chemicals in just a few hours, reports a new study led by environmental engineering researchers at UC Riverside. The addition of iodide accelerates the speed of the reaction up to four times, saving energy and chemicals.  “Iodide is really doing some substantial work,” said corresponding author Jinyong Liu, an assistant professor of chemical and environmental engineering. “Not only does it speed up the reaction but it also allows the treatment of a ten times higher concentrations of PFAS, even some very recalcitrant structures.” ... ”  Read more from UC Riverside here: PFAS chemicals do not last forever:The use of sulfite and iodide under ultraviolet light can destroy PFAS in water in a few hours
