Bellwether for a drying delta

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.

Finding the ‘sweet spots’ for managed aquifer recharge

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.

Airborne radar reveals groundwater beneath glacier

Researchers have detected groundwater beneath a glacier in Greenland for the first time using airborne radar data. If applicable to other glaciers and ice sheets, the technique could allow for more accurate predictions of future sea-level rise.

Oceans examined through historical and literary lenses

With a publication date coinciding with Earth Day, a new, six-volume set edited by Stanford English Professor Margaret Cohen explores the cultural history of Earth’s oceans from antiquity to the modern era.

New tool aims to amplify groundwater with floodwater

Using a new computer framework, scientists are able to project future floodwaters under a changing climate. The approach could help California water managers plan for and redirect floodwaters toward groundwater aquifers, alleviating both flood and drought risks.

Can extreme melt destabilize ice sheets?

Researchers have deciphered a trove of data that shows one season of extreme melt can reduce the Greenland Ice Sheet’s capacity to store future meltwater – and increase the likelihood of future melt raising sea levels.

Jordan’s worsening water crisis a warning for the world

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.

Research and policy in a changing Arctic

Stanford University scholars discuss the Biden administration’s early actions on environmental issues in the Arctic and how the U.S. government can address threats to ecosystems, people and infrastructure in the fastest-warming place on Earth.

The future of America’s drinking water

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.

How much do humans influence Earth’s water levels?

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.

A new way to forecast beach water quality

Using water samples and environmental data gathered over 48 hours or less, Stanford engineers develop a new predictive technique for forecasting coastal water quality, a critical step in protecting public health and the ocean economy.

Linking piped water, health and gender equality

New Stanford research finds installing piped water in rural Zambian homes frees up time in the daily lives of women and girls, while also promoting economic growth and food security – making an argument for piped water infrastructure investments across rural, low-income areas.

Climate change caused one-third of historical flood damages

Flooding has caused hundreds of billions of dollars in damage in the U.S. over the past three decades. Researchers found that 36 percent of the costs of flooding in the U.S. from 1988 to 2017 were a result of intensifying precipitation, consistent with predictions of global warming.

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.

Could kelp help relieve ocean acidification?

A new analysis of California’s Monterey Bay evaluates kelp’s potential to reduce ocean acidification, the harmful fallout from climate change on marine ecosystems and the food they produce for human populations.

Predicting urban water needs with Zillow and census data

New Stanford research uses Zillow and census data combined with machine learning to identify residential water consumption based on housing characteristics. The approach could help cities better understand water use and design water-efficient communities.

Cape Town’s ‘Day Zero’ drought a sign of things to come

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.

Protecting water

Federal regulators have moved to delay assessment and action on chemicals that could contaminate drinking water. Richard Luthy explains how the U.S. Environmental Protection Agency and individual states approach waterborne threats.

Studying whales with high-tech tools

With innovative tools and access to some of the most whale-friendly waters in the world, Stanford researchers aim to demystify the lives, biology and behavior of the largest creatures on Earth.

A simple way to reduce mosquito-borne diseases

Stanford researchers working in rural Kenya have identified the most productive breeding habitats for mosquitoes that spread a range of untreatable viruses. Their findings point to more effective health interventions that focus on the purpose of water-holding containers.

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.

Water heaters’ methane leaks are high, but fixable

Emissions of methane, a potent greenhouse gas, from water heaters are higher than previously estimated, especially for a new type of heater growing in popularity, a new Stanford study finds. But simple fixes exist.

Understanding spread of COVID-19

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

Stanford Program on Water, Health & Development —

Water and climate

Mismanagement, growing demand and climate change impacts, such as droughts and floods, strain limited water supplies around the world. Stanford researchers are developing innovative solutions that meet society’s water needs.

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.
