Drilling a single oil or natural gas well with hydraulic fracturing requires between 1.5 to 16 million gallons of water. When the well starts flowing, the fluid that is brought back to the surface alongside the oil and gas is a combination of the injection fluid and brine from aquifers – a difficult-to-treat mixture known as…

As world population grows, so do concerns that water availability and water quality will continue to diminish. Changes in land use, climate change, and extreme weather exacerbate these concerns, which threaten not only our fresh water supply but also systems that rely on watershed exports, such as hydropower and agriculture. Although watersheds are recognized as…

Growing up in Ethiopia’s Addis Ababa, Tadewos Getachew witnessed firsthand the lack of access to clean drinking water. He closely watched the city grapple with infrastructure challenges related to treating waste water or fixing leakages in the water distribution system. Getachew realized that he wanted to develop engineering solutions. “I wanted to build a…

Last week’s massive southern California earthquakes shut down Ridgecrest Regional Hospital throughout the July 4 holiday weekend while the tiny town of Ridgecrest assessed the damages. A new optical sensor developed at Lawrence Berkeley National Laboratory (Berkeley Lab) could speed up the time it takes to evaluate whether critical buildings like these are safe to occupy…

Berkeley Lab scientists (from left) Deborah Agarwal, Juliane Mueller, Reetik Sahu, Bhavna Arora, and Charuleka Varadharajan are developing a computational tool for smarter groundwater management. (Credit: Marilyn Chung/Berkeley Lab) The overpumping of groundwater in California has led to near environmental catastrophe in some areas – land is sinking, seawater is intruding, and groundwater storage capacity…

Long ago, during the European Renaissance, Leonardo da Vinci wrote that we humans “know more about the movement of celestial bodies than about the soil underfoot.” Five hundred years and innumerable technological and scientific advances later, his sentiment still holds true. But that could soon change. In a report published in Nature Communications, a…

A recent workshop held at the Berkeley Institute for Data Science focused on how to apply hydrologic transport data skills to real-world hydrologic problems. Zexuan Xu, an EESA postdoctoral fellow, coordinated the May event, “Critical Timescales of Hydrologic Transport.” Zexuan is currently working as part of a team of researchers studying ecosystem changes in a…

On May 15, 2019, the California Energy Commission awarded a $4.9 million grant to a multi-institutional project team led by UC Berkeley’s Pacific Earthquake Engineering Center (PEER) to improve the seismic risk assessment of natural gas storage and pipeline infrastructure. As part of this project, Berkeley Lab’s Energy Geosciences Division will receive $1.084 million to…

Methane, a potent greenhouse gas that traps about 30 times more heat than carbon dioxide, is commonly released from rice fields, dairies, landfills, and oil and gas facilities – all of which are plentiful in California. Now the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has been awarded $6 million by the state…

Wastewater is treated by an activated sludge process in municipal wastewater treatment plants and returned to the environment for use. This treatment process has been used for over a century, and today represents the largest application of biotechnology in the world, yet there has been no effort to map the global activated sludge microbiome. A…
