California acts to halt Kings County’s groundwater overpumping

“Kings County growers will face millions of dollars in fees and a mandate to report groundwater pumping after California officials voted unanimously today to put local agencies on probation for failing to protect the region’s underground water supply.  The unprecedented decision is a first step that could eventually lead to the state wresting control of a groundwater basin in a severely depleted part of the San Joaquin Valley.  Before issuing the probation order, the State Water Resources Control Board had repeatedly warned five groundwater agencies in Kings County that their management plan for the Tulare Lake basin is seriously deficient, failing to rein in the dried-up wells, contaminated water and sinking earth worsened by overpumping. …  ”  Read more from the Cal Matters.

California state water board places Tulare Lake Subbasin on probation

“California’s state water board Tuesday placed the Tulare Lake Subbasin on a probationary status, a first-of-its-kind move that will impose fees and reporting requirements on those who take water from the area.  The probationary status — imposed after a day-long hearing involving water board staff and local agency presentations, as well as public comment — stems from a groundwater sustainability plan that sought to remedy the critical overdraft from the basin. More water is pulled from the basin than rain and other sources can recharge, which leads to subsidence, a sinking of land that can damage infrastructure, as well as lowered aquifers.  A 2014 law, the Sustainable Groundwater Management Act, requires certain groundwater agencies to submit sustainability plans. Five water agencies that manage the Tulare subbasin submitted a joint plan, which didn’t meet muster last year. That failure triggered the State Water Resources Control Board to step in and, at the end of Tuesday’s day-long meeting, follow its staff’s recommendation and place the subbasin on probation. … ”  Read more from the Courthouse News Service.

Delta coalition files lawsuit demanding State Water Board action on DWR’s outdated water rights before considering Delta Conveyance Project approval

“After waiting 14 years, water rights protestants to a 2009 proceeding filed a complaint against the State Water Resources Control Board (State Board) alleging it has given preferential treatment to the Department of Water Resources (DWR) regarding antiquated water rights claims, and failed to implement state laws requiring the reasonable and equitable development of water diversions and the protection of water resources in the State. DWR is still relying on water rights permits for the development of the controversial Delta Conveyance Project that were issued in 1955 and 1972, despite dramatic changes in the population size of California and in the hydrological cycle due to climate change. The complaint alleges that DWR has failed to comply with state water rights law requiring water rights be timely put to full beneficial use; the purpose of this requirement is to safeguard the public interest. … ”  Continue reading this press release.

Water pollution is fueling ocean acidification. Environmentalists urge California to act

“As the burning of fossil fuels and other human activities continue to increase the levels of carbon dioxide in the atmosphere, the ocean is absorbing a large portion of the CO2, which is making seawater more acidic.  The changing water chemistry in the ocean has far-reaching effects for plankton, shellfish and the entire marine food web.  And here’s one important fact about ocean acidification: It’s not happening at the same rate everywhere.  The California coast is one of the regions of the world where ocean acidification is occurring the fastest. And researchers have found that local sources of pollution are part of the problem.  In particular, effluent discharged from coastal sewage treatment plants, which has high nitrogen levels from human waste, has been shown to significantly contribute to ocean acidification off the Southern California coast. … ”  Read more from the LA Times.

Environmental groups call for action to curb California’s coastal hot spots caused by ocean acidification and hypoxia

“Recently, California Coastkeeper Alliance, the Natural Resources Defense Council, and a coalition of environmental organizations called on Governor Newsom, the State Legislature and state agencies to take immediate and decisive action to protect California’s coast from the alarming impact of ocean acidification and hypoxia.  Recent research has shown that land-based nutrients discharged to the ocean from large coastal wastewater facilities are linked to ocean acidification and the loss of oxygen, creating ocean acidification and hypoxia hot spots. During late summer months, magnified by daily coastal sewage treatment plant discharges, ocean acidification and hypoxia hot spots form, causing marine habitat compression on average of 20% but up to 60% (vertically) for 25% (horizontally – over 1,000 square miles) of the Southern California Bight; even at distances of up to 50 miles offshore. … ”  Continue reading this press release.

Land-use bill taps farmland for solar sites

“Proposed state legislation to modify California’s longstanding farmland conservation law could pave the way for large swaths of farm acreage to be repurposed as sites for renewable energy projects.  The California Land Conservation Act of 1965, commonly known as the Williamson Act, preserves farmland by assessing property taxes based on the land’s agricultural value rather than its full market value. Landowners with Williamson Act contracts, which cover about half the state’s 30 million acres of farm and ranchland, generally see a 20% to 75% reduction in property taxes.  The contracts are agreed between landowners and counties or cities and can only be dissolved by paying a fee of 12.5% of the land value or through a nonrenewal process that takes nine years. … ”  Read more from Ag Alert.

The west has a new way to save water

“Solar panels could one day help ease water shortages in the Colorado River Basin, and its integral reservoirs such as Lake Mead in America’s West, a professor has told Newsweek.  A University of California Merced study showed how covering 4,000 miles of canal with the panels in the state could result in huge savings for the state in water as well as energy. Researchers say 63 billion gallons of water could be conserved annually, enough for the needs of 2 million people and irrigation across 50,000 acres of agricultural land.  “Covering open canals in the Colorado River basin should be as effective as in California,” Roger Bales, a distinguished professor of engineering, at UC Merced, who worked on the study, told Newsweek. … ”  Read more from Newsweek.

How cloud seeding works and why it’s wrongly blamed for floods from Dubai to California

In a place as dry as the desert city of Dubai, whenever they can get rain, they’ll take it.  United Arab Emirates authorities will often even try to make it rain—as they did earlier this week when the National Center of Meteorology dispatched planes to inject chemicals into the clouds to try to coax some showering.  But this time they got much more than they wanted. … The UAE government media office said it was the heaviest rainfall recorded in 75 years and called it “an exceptional event.” More than a typical year’s worth of water was dumped on the country in a single day.  Now, many people are pointing a finger at the “cloud seeding” operations preceding the precipitation.  “Do you think the Dubai floods might have something to do with this?” popular social media account Wide Awake Media asked on X, alongside a clip of a news report on the UAE’s weather modification program. … ”  Read more from Time Magazine.

California has $500,000 available for each initiative statewide for agricultural producers.  “It is our mission to support producers in addressing their resource concerns as well as protect our wildlife,” said NRCS California State Conservationist Carlos Suarez. “These two important initiatives help our California producers improve their operations to keep habitat for critical avian species healthy, safe, and abundant, while keeping our farmers farming.” … ”  Continue reading from Morning Ag Clips.

Fifth District Appellate Court revisits King & Gardiner farms, now finding agricultural conservation easements may be required under CEQA as partial mitigation for project’s conversion of agricultural land

“In a partially published opinion—V Lions Farming, LLC v. County of Kern (2024) 100 Cal.App.5th 412—the Fifth District Court of Appeal held that even though agricultural conservation easements (ag easements) may only partially mitigate a project’s conversion of agricultural land, those easements are not obsolete under the California Environmental Quality Act (CEQA).  As background, agricultural land is defined by CEQA as “prime farmland, farmland of statewide importance, or unique farmland, as defined by the [USDA] land inventory and monitoring criteria, as modified for California.” (Pub. Resources Code, § 21060.1 (a).) In 2015, Kern County approved an ordinance streamlining the permitting process for new oil and gas wells, and the environmental impact report (EIR) prepared for that ordinance used a no-net-loss threshold of significance for agricultural land. … ”  Read more from Somach Simmons & Dunn.

Beavers are our partners in protecting and restoring California

Kate Lundquist and Brock Dolman, Co-Directors of the Watershed Advocacy, Training, Education, & Research (WATER) Institute and the Bring Back the Beaver Campaign at the Occidental Arts & Ecology Center, write, “If you’re like us, you’re inspired by the natural world and eager to see California’s beautiful mountains, forests, and lakes protected for future generations. You also might be surprised to hear that the health and survival of these places depends on one species more than most: beavers. Put simply, beavers are our partners in protecting and restoring California.  Beavers are known as a “keystone species,” meaning they create, modify, and maintain critical ecosystems for insects, birds, mammals, fish, plants, and trees. In fact, 50% of North America’s threatened or endangered species are highly dependent upon beavers for their survival. Beavers primarily live in riparian areas such as rivers, wetlands, and mountain meadows, areas which are similarly known as “keystone ecosystems.” When these habitats are healthy and thriving, this has disproportionate benefits for other ecosystems too. As a result, preserving riparian areas can have an outsized impact on conservation efforts locally and statewide. … ”  Read more from Capitol Weekly.

Klamath irrigators express frustration over allocation

“Despite favorable conditions in the Klamath Basin, irrigators say the initial federal water allocation falls short of what farmers in the Klamath Water Project should receive this year.  The U.S. Bureau of Reclamation, which manages the project, announced this week that Klamath Basin irrigators will receive an initial allocation of 230,000 acre-feet from the lake. That is 35% less than estimated needs, said Paul Simmons, executive director and counsel for the Klamath Water Users Association.  “Within a few weeks, Upper Klamath Lake will be completely full for the first time in seven years, and the snowpack is in good shape for this time of year, yet we are looking at the fifth-worst allocation in the 120 years since the Klamath Project was authorized,” said Simmons, who called the allocation “deeply disappointing.” “Because of the way the internal distribution of water works, we are looking at family farms that will go without water for the fifth straight year.” … ”  Read more from Ag Alert.

Work to repair damage from deluge continues

“From Sequoia Park to the old Tulare Lake bed, local authorities recount the same story. A deluge of biblical proportions, including heavy rain and storm runoff, in the past year in the Kaweah, Kings and Tule basins has caused hundreds of millions of dollars in damage to the region’s road and bridge infrastructure. A series of atmospheric rivers, particularly in March 2023, sent floodwaters from the foothills streaming down to the valley floor, gushing through the streets of small communities in Tulare and Kings County and into the western part of the basin, re-creating historic Tulare Lake near Corcoran. At its peak last summer, the lake sprawled over 111,000 acres, still a fraction of its historical size of nearly 512,000 acres (800 square miles), and five to seven feet deep. “We all prayed for rain. We just all prayed a little too hard,” one source remarked. … ”  Read more from the Foothills Sun-Gazette.

California Water Service finds potential ‘forever chemicals’ in 22 Bakersfield wells

“The California Water Service in Bakersfield has found that 22 of its water wells could be contaminated with ‘forever chemicals’, also known as PFAS.  The water utility company came across these findings when they tested several of their wells ahead of the Environmental Protection Agency’s introduction of new PFAS guidelines.  The EPA has grown increasingly concerned over forever chemicals. Long-term exposure has been linked to health problems such as kidney cancer. This is why the EPA created new rules that water utility companies, including Cal Water Bakersfield, must meet. … ”  Read more from Bakersfield Now.

Saguaro population decline in Arizona

“Saguaro National Park is a mainstay for those who come to visit southern Arizona, however, the iconic plant has seen a decrease in young cacti in recent years.  Saguaros are one of the least understood plants by experts even though they have been studied closely at Saguaro National Park since the early 40’s. The big reason why is because they grow very slowly and many are decades old.  Drought has an impact on the cactus, but it’s a combination of a couple of different factors that could affect the plant.  Don Swann is a biologist at the park and he said, “Drought is a combination of both temperatures and rainfall. That can exacerbate the effects of not having too much rain. Saguaros really need moisture when they are little and when they are very tiny they can barely store any water at all.” … ”  Read more from Channel 4.

Native American voices are finally factoring into energy projects – a hydropower ruling is a victory for environmental justice on tribal lands

“The U.S. has a long record of extracting resources on Native lands and ignoring tribal opposition, but a decision by federal energy regulators to deny permits for seven proposed hydropower projects suggests that tide may be turning.  As the U.S. shifts from fossil fuels to clean energy, developers are looking for sites to generate electricity from renewable sources. But in an unexpected move, the Federal Energy Regulatory Commission denied permits on Feb. 15, 2024, for seven proposed hydropower projects in Arizona and New Mexico.  The reason: These projects were located within the Navajo Nation and were proposed without first consulting with the tribe. FERC said it was “establishing a new policy that the Commission will not issue preliminary permits for projects proposing to use Tribal lands if the Tribe on whose lands the project is to be located opposes the permit.” … ”  Read more from The Conversation.

Removing PFAS from public water will cost billions and take time – here are ways to filter out some harmful ‘forever chemicals’ at home

Chemists invented PFAS in the 1930s to make life easier: Nonstick pans, waterproof clothing, grease-resistant food packaging and stain-resistant carpet were all made possible by PFAS. But in recent years, the growing number of health risks found to be connected to these chemicals has become increasingly alarming.  PFAS – perfluoroalkyl and polyfluoroalkyl substances – are noweither suspected or known to contribute to thyroid disease, elevated cholesterol, liver damage and cancer, among other health issues.  They can be found in the blood of most Americans and in many drinking water systems, which is why the Environmental Protection Agency in April 2024 finalized the first enforceable federal limits for six types of PFAS in drinking water systems. The limits – between 4 and 10 parts per trillion for PFOS, PFOA, PFHxS, PFNA and GenX – are less than a drop of water in a thousand Olympic-sized swimming pools, which speaks to the chemicals’ toxicity. The sixth type, PFBS, is regulated as a mixture using what’s known as a hazard index. … ”  Continue reading at The Conversation.
