Removing salt from seawater to make it safe to drink means overcoming a number of scientific challenges, including optimizing the membrane used for the desalination process – and new research into these membranes promises to make the whole operation cheaper and more accessible in the future.
The Santa Clara Valley Water District has been lowering the water level on the Anderson Dam since Oct. 1 to keep the region safe from potentially catastrophic flooding in the event of a major earthquake.
The Anderson Reservoir can hold up to 90,000 acre-feet of water and is now at three percent capacity, which is the lowest feasible level given the position of the existing outlet tunnel. At its current level, even a heavy rainy season would not pose dam failure and flooding risk; keeping some water in the reservoir helps preserve some wildlife habitat. Beyond immediate safety, one of the main reasons for lowering the water level is to allow for construction to begin on a major seismic retrofit project for the dam. The reservoir has been closed for recreational use since October and is expected to remain shuttered for the duration of the project.
In a major and potentially fatal setback for plans to build the largest dam in the Bay Area in more than 20 years, the price tag to construct a new reservoir in southern Santa Clara County near Pacheco Pass has nearly doubled, from $1.3 billion to $2.5 billion.
After years of build up, a giant battery storage project is online in Moss Landing, California, and a huge one is on the way in Florida.
California isn’t meeting its recycled water goals, and billions of gallons of treated wastewater are being discharged into the ocean or other water bodies each year, according to state regulators, who say drought conditions could cause future supply challenges.
Since the Clean Water Act passed in 1972, the assumption has been that all waterways are protected from pollution — meaning that rivers, streams, lakes, and wetlands are, by law, shielded from industrial and agricultural waste through a strict permitting process via the federal government.
The old axiom goes, “Whiskey’s for drinkin’ and water’s for fightin'” — it reflects the never-ending horse-trading that involves distribution of water in the arid Southwest and the tug of war between the region’s agricultural communities and the ever-growing urban centers, including Las Vegas, Phoenix and areas of Southern California. Traditionally, water rights have been brokered by state and local governments, as well as regional water districts.
Growers considering producing avocados in San Diego County with high-density plantings now have help to determine the economic feasibility. A new study on the costs and returns of establishing and producing avocados in San Diego County has been released by UC Agriculture and Natural Resources’ Cooperative Extension, UC Agricultural Issues Center and the UC Davis Department of Agricultural and Resource Economics.
Now that the calendar has flipped to January 2021, it’s time to say goodbye to the mess of the past year, yes? The baggage from 2020 was discarded, left behind at the station when the clock struck midnight, right? Appealing as that might be, the answer is no. Far from being in the rearview, the upheaval of the last year will set the stage for the next 12 months and beyond.
Happy new year! We all know keeping New Year’s resolutions is often a fruitless endeavor, but here’s hoping that Mother Nature will make—and keep—a resolution for a less bonkers climate year in 2021. To kick start 2021 in the United States, the January outlook from NOAA’s Climate Prediction Center favors wetter- and warmer-than-average conditions for much of the country, which is particularly good news across drought- and wildfire-stricken parts of northern California.
