Is it safe to use oilfield wastewater on crops?2 min read

Is it safe to use treated oilfield wastewater to irrigate almond, pistachio and citrus groves? William Stringfellow, environmental engineer in Earth and Environmental Sciences (Energy Geosciences Division), says, “We’re not able to answer the public definitely, and say there’s no problem.” Dr. Stringfellow joins a new panel, “Regional Water Quality Control Board Food Safety Expert Panel,” that has been charged to study the safety of irrigating food crops with oilfield wastewater from hydraulic fracturing, other drilling methods, and oilfield maintenance that contain chemicals, not only those naturally occurring in underground formations, but proprietary additives used to maximize oil extraction.

California’s oilfields generate lots of wastewater—nearly two billion barrels in 2013. With the extended California drought, the recycled wastewater is already irrigating tens of thousands of acres in California. In the Cawelo Water District, which has used treated water from Chevron and Valley Water Management since 1995, the water accounts for roughly 30% of the district’s supply.

The Central Valley Regional Water Quality Control Board has assembled this panel to study the safety of produce irrigated with this recycled water which may contain hundreds of chemicals, many unidentified or of known toxicity. The panel’s first public meeting was held on January 12 in Sacramento, California.

Study Sheds Light on Microbial Communities in Earth’s Subsurface2 min read

August 16, 2023

  From the tops of tree canopies to the bottom of groundwater reservoirs, a vast amount of living organisms interact with nonliving components such as rock, water, and soil to shape this area of Earth known as the “critical zone.” Over half of Earth’s microbes are located in the subsurface critical zone, which ranges from…

The contributions of Carl Steefel to the reactive transport modeling scientific community were recognized in a session held in his honor at the recent Goldschmidt 2023 conference (Lyon, France). Goldschmidt is the foremost annual, international conference on geochemistry and related subjects, organized by the European Association of Geochemistry and the Geochemical Society. The session was…

DOE Funds Projects to Advance Forest Carbon Dioxide Removal Efforts and Agricultural Soil Carbon Conservation4 min read

August 1, 2023

The DOE Office of Fossil Energy and Carbon Management (FECM) and Office of Technology Transitions (OTT) recently announced $5 million in funding for four projects–two from Berkeley Lab with EESA leadership. The projects selected offer “promising solutions” to the nation’s climate change challenges by helping to reduce greenhouse gas emissions and will “accelerate their deployment…

This article first appeared at nature.berkeley.edu/news. The world’s forests, grasslands, and other terrestrial ecosystems have played a substantial role in offsetting human carbon emissions—a capability that UC Berkeley researchers say would be threatened by continued global change. The assessment, published today as a new review paper in Nature Reviews Earth & Environment, presents a comprehensive analysis of…
