Poof! Plans Underway to Transform Sewage Into Electricity, Clean Water

/in , , /by /The OC Registerby Martin Wisckol

It’s like a magic trick for poop. Put it in one end of the machine, and out the other comes electricity, distilled water and a small amount of ash. And there’s none of the greenhouse gas — namely methane — produced by traditional sewage treatment and sewage sludge decomposition.

Though it might seem futuristic, this innovative blueprint has attracted grants from the U.S. Department of Energy and the California Energy Commission, the latter to the tune of $1.6 million. The money is helping to fund a demonstration project at south Orange County’s Santa Margarita Water District. Partners include Stanford University’s Codiga Resource Recovery Center.

California Drought: Santa Clara County Residents Failing to Meet Water Conservation Goals

/in , , /by /Mercury Newsby Paul Rogers

On June 9, as California’s historic drought deepened, the largest water agency in Santa Clara County declared a drought emergency and asked the county’s 2 million residents to cut water use by 15% from 2019 levels to preserve dwindling supplies.

Wildfires are Putting Water Supplies at Risk, and Corporate America is Scared

/in , , /by /CNBCby Diana Olick

As wildfires tear across America’s West, the immediate risk is to life and property, but they will eventually affect water supplies.

That’s one reason large corporations are beginning to help fund forest restoration in order to mitigate their water risk.

The water supply for many communities, including large cities, starts in mountains and national forests. In California, about 70% of the water either starts or flows through national forests, according to Forest Service estimates.

La Niña Responsible for Megadroughts in North and South America, Study Finds

/in , , /by /Courthouse News Serviceby Jon Parton

La Niña, the climate event that causes water to be colder than normal in the eastern Pacific, has now been shown by new research released Monday to be responsible for simultaneous megadroughts in the North and South American Southwest over the past 1,000 years.

Megadroughts are extended periods of drought that last at least 20 years. In a study published in the journal Nature, researchers found that these megadroughts occurred simultaneously in the North American and South American Southwest “regularly” and often during a La Niña event.

Proposed Change at Prado Dam Could Yield Water for 60,000 More People

/in , , /by /The Sunby Martin Wisckol

Enough water for 60,000 Orange County residents can be generated by more efficient release of rainwater from the Prado Dam into the Santa Ana River, according to a new multi-agency report.

During a year of average rainfall, that’s the amount of water currently flowing into the ocean that could be captured for urban use, according to the two co-chairmen of the committee overseeing project. The proposed plan, slated to begin phasing in next year, would enable more rainwater to be absorbed into the county’s major groundwater basin before it reaches the Pacific.

Could Desalination Play a Role in the Future of the Colorado River?

Shattering the stillness of a frigid January moonlit sky, the sunrise’s amber aura glimmers over the Tinajas Altas mountain range — giving way to a sandscape of semi-succulent shrubs.

The sun’s increasingly insistent rays animate an otherwise desolate desert corridor that links the city of Yuma, Arizona, to the San Luis Port of Entry along the U.S.-Mexico border. White school buses shuttle Mexican agricultural workers to Arizonan farm acreage, home to America’s heartland of winter leafy greens.

Lithium Fuels Hopes for Revival on California’s Largest Lake

/in , , /by /AP Newsby Elliot Spagat

Near Southern California’s dying Salton Sea, a canopy next to a geothermal power plant covers large containers of salty water left behind after super-hot liquid is drilled from deep underground to run steam turbines. The containers connect to tubes that spit out what looks like dishwater, but it’s lithium, a critical component of rechargeable batteries and the newest hope for economic revival in the depressed region.

Demand for electric vehicles has shifted investments into high gear to extract lithium from geothermal brine, salty water that has been overlooked and pumped back underground since the region’s first geothermal plant opened in 1982. The mineral-rich byproduct may now be more valuable than the steam used to generate electricity.

‘Forever Chemicals’ Found in Groundwater Near Military Bases

High levels of toxic, widely used “forever chemicals” contaminate groundwater around at least six military sites in the Great Lakes region, according to U.S. Department of Defense records that an environmental group released Tuesday.

The Environmental Working Group said PFAS, an abbreviation for perfluoroalkyl and polyfluoroalkyl substances, have oozed into the Great Lakes and pose a risk to people who eat fish tainted with the chemicals.

Federal Judge Throws Out Trump Administration Rule Allowing the Draining and Filling of Streams, Marshes and Wetlands

/in , , /by /The Washington Postby Dino Grandoni and Brady Dennis

A federal judge Monday threw out a major Trump administration rule that scaled back federal protections for streams, marshes and wetlands across the United States, reversing one of the previous administration’s most significant environmental rollbacks. U.S. District Judge Rosemary Márquez wrote that Trump officials committed serious errors while writing the regulation, finalized last year, and that leaving it in place could lead to “serious environmental harm.”

These Before-After Images of Bay Area Reservoirs Show Drought’s Severe Impact

/in , , /by /The San Francisco Chronicleby Jessica Flores

Water levels at several Bay Area reservoirs have reached historical lows — just one of the devastating environmental impacts of California’s punishing drought, the Santa Clara Valley Water District said Wednesday.

Reservoirs operated by Valley Water, the main provider in Santa Clara County, were 85% full in April 2017, the agency said. As of Wednesday morning, they were at 12.5%. Then-and-now images illustrating how low the reservoirs have dwindled reinforced the agency’s grim report.
