Freshwater resources

Downstream of hydroelectric dams and Alberta’s oil sands, one of the world’s largest freshwater deltas is drying out. New Stanford University research suggests long-term drying is making it harder for muskrats to recover from massive die-offs. It’s a sign of threats to come for many other species.

Rapidly worsening drought and a mandate to bring aquifer withdrawals and deposits into balance by 2040 have ignited interest in replenishing California groundwater through managed aquifer recharge. Stanford scientists demonstrate a new way to assess sites for this type of project using soil measurements and a geophysical system towed by an all-terrain vehicle.

New research focused on interactions among microbes in water suggests fungal microparasites play a bigger than expected role in aquatic food webs and the global carbon cycle.

Women exposed to higher levels of nitrate in drinking water were more likely to deliver very early, according to a study of 1.4 million California births.

Prolonged and potentially destabilizing water shortages will become commonplace in Jordan by 2100, new research finds, unless the nation implements comprehensive reform, from fixing leaky pipes to desalinating seawater. Jordan’s water crisis is emblematic of challenges looming around the world as a result of climate change and rapid population growth. 

The Biden administration’s ambitious plans for environmental progress face complex obstacles. The findings, expertise and policy experience of Stanford researchers working across multiple fields could help contribute to sustainable, cost-effective solutions.

Naming priorities such as better land management, an evolved portfolio of 21st-century solutions and more funding for research and development, Stanford experts highlight areas central to success as the Biden-Harris administration aims its sights on safeguarding U.S. drinking water.

A new study provides the first global accounting of fluctuations in lake and reservoir water levels. The research shows 57 percent of the variability occurs in dammed reservoirs and other bodies of water managed by people, highlighting the dominant role humans now play in Earth’s water cycle.

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.

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.

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.

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.

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.

A recent executive order empowers federal agencies to override legal requirements for environmental reviews and community feedback related to major infrastructure projects. Intended to help kickstart the economy, the order could cause disproportionate damage to poor communities and communities of color.

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.

New research suggests dry air combined with 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.

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.

A new study identifies a connected pattern of drought followed by heavy rain in regional hotspots around the globe.

As climate change and population growth make drinking water costlier, here are six strategies to quench the state’s thirst without busting its budget.

Stanford professor Alexandria Boehm and visiting scholar Krista Wigginton describe potential transmission pathways of COVID-19 and their implications.

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.

New research maps impacts of hydropower dams on species critical to human livelihoods.

In regions that lack the resources to treat the contaminated water, it can lead to disease, cancer, and even death.

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.
