New study allows regional prediction of uranium in groundwater
Stanford researchers can predict where and when uranium is released into aquifers and suggest an easy fix to keep this naturally occurring toxin from contaminating water sources.
What wastewater can reveal about COVID-19
A new wastewater testing approach capable of better detecting viral infection patterns in communities could prove a crucial step toward an informed public health response to diseases like COVID-19.
Flying the foothills
Stanford researchers, in collaboration with groundwater managers, are leading an airborne survey effort to investigate where water from the Sierra Nevada Mountains could recharge groundwater aquifers in California’s Central Valley.
In a warming world, Cape Town’s ‘Day Zero’ drought won’t be an anomaly
Using new high-resolution simulations, researchers conclude that climate change made the Cape Town ‘Day Zero’ drought five to six times more likely and suggest extreme drought events could become common in southwestern South Africa by the end of the 21st century.
Newly identified 'landfalling droughts' originate over ocean
Researchers have identified a new type of “landfalling drought” that originates over the ocean before traveling onto land, and which can cause larger, drier conditions than other droughts.
Gravity wave insights from internet-beaming balloons
A better understanding of how gravity waves in the upper atmosphere interact with the jet stream, polar vortex and other phenomena could be key to improved weather predictions and climate models.
Exploring the sustainability of the Indian sugar industry
Researchers analyzed the interconnected food, water and energy challenges that arise from the sugar industry in India – the second-largest producer of sugar worldwide – and how the political economy drives those challenges.
Understanding environmental rollback
In a Q&A, environmental law Professor Deborah Sivas discusses a recent executive order that empowers federal agencies to override legal requirements for environmental reviews and community feedback related to major infrastructure projects.
Accounting for nature in economies
Gross Domestic Product, the standard metric for measuring national economies, doesn’t account for the valuable services provided by nature. A new approach could help fill the gap.
Desalination solution
Desalination – the conversion of saltwater to freshwater – has been limited by high operational costs. A new device capable of turning desalination waste into commercially valuable chemicals could make the process cheaper and more environmentally friendly.
Predicting plant water needs in a warmer, drier world
New research suggests dry air and warmer temperatures may prompt bigger than expected changes in how water moves through plants. The adjustment may allow plants to survive with less water in future droughts, while downshifting how much carbon they absorb.
Double-whammy weather
Like an undulating seesaw, weather in some regions swings from drought to heavy rain under the weight of climate-induced changes, a new study finds.
Less water could sustain more Californians if we make every drop count
As climate change and population growth make drinking water costlier, here are six strategies to quench the state’s thirst without busting its budget.
Understanding spread of COVID-19
Much remains unknown about how the virus that causes COVID-19 spreads through the environment. Environmental engineers describe potential transmission pathways and their implications.
A better way to detect underground water leaks
Stanford researchers propose a new way to locate water leaks within the tangle of aging pipes found beneath many cities. The improvement could save time, money and billions of gallons of water.
Hydropower dams threaten fish habitats worldwide
New research maps the impacts of past and future hydropower development on fish habitats – and points to where restoration efforts may do the most good.
Rust offers a cheap way to filter arsenic-poisoned water
In regions that lack the resources to treat the contaminated water, it can lead to disease, cancer and even death.
More rain and less snow means increased flood risk
By analyzing more than two decades of data in the western U.S., scientists have shown that flood sizes increase exponentially as a higher fraction of precipitation falls as rain, offering insight into how flood risks may change in a warming world with less snow.
Q&A: How wildfires threaten water quality
Stanford hydrologist Newsha Ajami, an appointee to California’s regional water quality board, discusses how wildfires affect water quality, and how we can better prepare for and react to the challenges.
