Could the Answer to Groundwater Resources Come From High in the Sky?

/in , , /by /Berkeley Labby Christina Procopiou

Groundwater makes up 30 to 50 percent of California’s water supply, but until recently there were few restrictions placed on its retrieval. Then in 2014 California became the last Western state to require regulation of its groundwater. With deadlines starting this year, for the first time water managers in the nation’s premier agricultural region – the state’s Central Valley – are tasked with estimating available groundwater. It’s a daunting technological challenge.

In an effort to move forward a $576 million Anderson Dam Seismic Retrofit Project, the California State Assembly passed AB 3005 on June 8, the Expedited Dam Safety for Silicon Valley Act, facilitating the construction of the project.

Assemblyman Robert Rivas (D-Hollister, Calif.), who wrote the bill, says the overwhelming vote of bipartisan support shows the importance in fixing the dam. “The clock is ticking on a catastrophic dam failure in case of a large earthquake,” he says, “and we can’t allow bureaucratic delay to increase risks to public safety, water security and environmental protections.”

A 90% clean grid by 2035 would be cost-effective, says a report from UC Berkeley and GridLab; a companion policy paper calls for a federal renewables mandate to get there.

Under a 90% clean grid, wholesale electricity would cost less than it does today. And although a 55% clean grid in 2035 would have even lower electricity prices, when environmental and health damages from fossil fuel use are counted, the 90% clean grid would cost less.

City Attorney Mara Elliott says the price tag is too high and SDG&E has not properly documented the costs. The utility counters that it has substantiated its charges to city officials and the bill fairly represents work rendered.

As the coronavirus creeps through the human population, causing social and economic turmoil, farmers discard vast quantities of food that they are abruptly unable to sell in the upended economy. The waste has been widely reported as one heartbreaking impact of the Covid-19 crisis. Part of the problem seems to be that, with restaurants closed, vegetable farmers, as well as producers of milk, eggs and meat, wound up with no one to buy their goods.

Pure Water San Diego Projects Underway After Receiving Milestone Permit

/in , , /by /Water News Network

Pre-construction activities at the North City Water Reclamation Plant and the future Pure Water Facility are underway as part of Phase 1 of the Pure Water San Diego program. More than 80,000 cubic yards of soil have been moved to date during initial site work, the equivalent of approximately 25 Olympic sized swimming pools.

Last month, the San Diego Regional Water Quality Control Board adopted an order granting a National Pollutant Discharge Elimination System, or NPDES permit, to the City of San Diego to add purified water to the Miramar Reservoir for Phase 1 of the Pure Water San Diego program. The approval is a major milestone for the program.
