New Research Confirms El Niño Can Have Major Economic Impacts For California

/in , /by /ABC10 (Sacramento) by Rob Carlmark

The core findings by Thomas W. Corringham and Daniel R. Cayan from the Scripps Institution of Oceanography, University of California San Diego, confirm when it comes to flood claims and damages, El Niño is a force to be reckoned with. Wading through 40 years of ocean temperatures confirmation of El Niño and La Niña events, the authors discovered flood damage claims can be ten times higher during an El Niño year. El Niño is a phenomena that occurs far from California in the middle of the Pacific Ocean. A change in wind direction can send warmer water from the Western Pacific to the usually cooler Eastern Pacific.

New Delta Tunnel Project Begins Taking Shape

/in , , /by /The Press (Brentwood, Calif.)by Tony Kukulich

Opponents of the twin tunnels breathed a collective sigh of relief in April when Gov. Gavin Newsom put a formal end to the California WaterFix project, but that action also called for the assessment of a single-tunnel project in the Delta. The first major step in that direction took place last week when the Department of Water Resources (DWR) initiated a series of negotiations with public water agencies that participate in the State Water Project (SWP), to amend SWP contracts to accommodate the construction and operation of a single Delta tunnel, referred to as the Delta Conveyance Project. Of the 29 state contractors, five agencies that operate north of the Delta are expected to opt out of participation in the project.

How PFAS Poses An Emerging Problem For Wastewater

/in , /by /Water Online

The intrusion of PFAS into source water supplies has grabbed the regulatory spotlight. As more scientists and health professionals raise concerns about the compounds — technically known as per- and polyfluoroalkyl substances — federal and state environmental agencies are under increasing pressure to impose limits for public protection. Now, it seems that municipalities have another looming headache as PFAS is finding its way into wastewater.

The California State Board of Food and Agriculture is hosting a series of public forums to allow farmers, ranchers and other stakeholders opportunities to provide input on the California’s Water Future. A meeting is set for 1-3:30 p.m. Tuesday, Aug. 6 at the Sheraton Redding Hotel at the Sundial Bridge, 820 Sundial Bridge Drive in Redding. State agencies are asking Californians to help shape a road map for meeting future water needs and ensuring environmental and economic resilience through the 21st century.

The Rapid Maturation Of The U.S. Energy Storage Market

/in , /by /PV Magazineby Amish Shah, Madeleine Tan, Kyle Hayes and Alyssa Walker

The U.S. energy storage market is primed to grow at a rapid pace. A study by IHS Markit forecasts that the U.S. grid-tied energy storage market will nearly double in 2019 – from 367 MW in 2018 to 712 MW this year – which does not include behind-the-meter energy storage that would add several hundred MW of deployed energy storage to the forecast for 2019. This significant expansion is poised to occur against a backdrop of regulatory changes in federal and state incentive programs, cost improvements and advances in monetization of energy storage. These current and anticipated trends affecting the U.S. energy storage market will have a significant influence on how industry participants choose when, where and how to invest in and develop energy storage technology.

Is Hetch Hetchy Worth $100 billion?

/in , , /by /San Francisco Chronicleby Gregory Thomas

Yosemite’s Hetch Hetchy Valley was dammed and flooded nearly 100 years ago, but the prospect of draining the reservoir continues to inspire romantic imaginings about unlocking a brand-new outdoor-recreation mecca in one of the country’s most popular national parks. If we could return Hetch Hetchy to a more natural state — of the variety that stirred John Muir’s soul a century ago — would we be clearing a path for the emergence of Yosemite Valley 2.0?

Dam Spillway Near SLO County Has Significant Cracks, Is ‘Unsafe For Use,’ State Says

/in , , /by /The Tribune by Monica Vaughan

Remember when the concrete spillway of the nation’s tallest dam developed a giant hole, and downstream communities were evacuated out of fear that a wall of water would charge down the river?

It turns out that the same structural problems that caused the failure at Oroville Dam in February 2017 also exist at the spillway of San Antonio Dam, just two miles north of Lake Nacimiento and above the community of Bradley.

Those problems have been known “for quite sometime,” according to the current manager of the dam operator. But the state didn’t take notice or downgrade the dam’s safety condition until after it revamped its oversight process following the massive failure in Northern California.

Water Systems Must Notify Californians About These Cancer-Linked Chemicals Under New Law

/in , , /by /The Sacramento Beeby Sophia Bollag

Starting next year, California water systems must notify residents if their water sources contain potentially toxic levels of cancer-linked chemicals called PFAS under a law Gov. Gavin Newsom signed Wednesday.

The new law, AB 756, will also expand state regulators’ ability to test for per-and polyfluoroalkyl substances, known as PFAS. The compounds can be found in everyday plastics and products like floss and are concentrated in firefighting foam that the military and commercial aviation industry has used for decades.

That foam has seeped into groundwater and wells surrounding military installations and commercial airports, and has been found in drinking water sources at more than 712 locations in 49 states, according to the Environmental Working Group, a nonprofit organization.

Opinion: Sites Reservoir Needed For Reliable Water Future

/in , , /by /San Francisco Chronicleby Andrew Meredith

A flexible, reliable water supply is essential to California’s economy and to the job creation and job security goals of California’s working families. Reliability and flexibility in our water supply has become elusive in drought-prone California, thanks in large part to a changing climate and an obsolete water storage system that was designed to utilize a steady and massive Sierra snowpack. It’s well past time to make critical investments in water infrastructure — particularly water storage — to sustain us through future droughts and help us adapt to our new normal, one which includes extended droughts, diminished snowpack, warmer winter storms and a need for a more flexible water storage portfolio.

Foreign Hackers Impersonated Professional Licensing Board In Attack On Utilities

/in , , /by /Utility Dive (Washington, D.C.)by Robert Walton

Security firm Proofpoint on Thursday said it uncovered an “advanced phishing campaign” that specifically targeted U.S. utility companies by impersonating an engineering licensing board. The firm said emails sent between July 19 and July 25 went to three utilities, which it declined to name. Messages purporting to be from the U.S. National Council of Examiners for Engineering and Surveying contained a malicious attachment that utilized macros to install and run malware named “LookBack.” The attempts highlight the “continuing global risk from nation-state actors,” according to Proopoint. In June, the United States’ chief energy regulator warned the electric grid is “increasingly under attack by foreign adversaries.”
