Scientists solve mystery of arsenic release into groundwater

Groundwater in South and Southeast Asia commonly contains concentrations of arsenic 20 to 100 times greater than the World Health Organization's recommended limit, resulting...

Study is first to map Earth’s hidden groundwater

Groundwater: it's one of the planet's most exploited, most precious natural resources. It ranges in age from months to millions of years old. Around...

California drought causing valley land to sink

As Californians continue pumping groundwater in response to the historic drought, the California Department of Water Resources has released a new NASA report showing...

Where Does Water Go When It Doesn’t Flow?

More than a quarter of the rain and snow that falls on continents reaches the oceans as runoff. Now a new study helps show...

A third of the world’s biggest groundwater basins are in distress

Two new studies led by UC Irvine using data from NASA Gravity Recovery and Climate Experiment satellites show that civilization is rapidly draining some...

Bacteria could help clean groundwater contaminated by uranium ore processing

A strain of bacteria that "breathes" uranium may hold the key to cleaning up polluted groundwater at sites where uranium ore was processed to...

Raising Groundwater Keeps Valleys from Sinking: Santa Clara Valley, California, USA

California and other parts of the western U.S. are experiencing extended severe drought conditions. Varying groundwater levels in valleys throughout the state, balanced by...

Lack of oxygen in the groundwater

Jena (Germany) Spring has arrived in Europe with mild temperatures and sunshine. Where just a few weeks ago the ground was frozen and partly...

Researchers find evidence of groundwater in Antarctica’s Dry Valleys

Using a novel, helicopter-borne sensor to penetrate below the surface of large swathes of terrain, a team of researchers supported by the National Science...

Gas leaks from faulty wells linked to contamination in some groundwater

A study has pinpointed the likely source of most natural gas contamination in drinking-water wells associated with hydraulic fracturing, and it's not the source...

Groundwater tied to human evolution

Our ancient ancestors' ability to move around and find new sources of groundwater during extremely dry periods in Africa millions of years ago may...

Fracking flowback could pollute groundwater with heavy metals

ITHACA, N.Y. – The chemical makeup of wastewater generated by “hydrofracking” could cause the release of tiny particles in soils that often strongly bind...

Groundwater could fuel life under glaciers

Subglacial lakes in Antarctica might have nutrient-rich groundwater flowing into them, say scientists investigating the origin of the water in ice streams. Ice streams are...

Study finds tungsten in aquifer groundwater controlled by pH, oxygen

MANHATTAN -- Two Kansas geologists are helping shed new light on how tungsten metal is leached from the sediment surrounding aquifers into the groundwater....

Breathing Underwater: Evidence of Microscopic Life in Oceanic Crust

Although long thought to be devoid of life, the bottom of the deep ocean is now known to harbor entire ecosystems teeming with microbes....

Water Hidden in the Moon May Have Proto-Earth Origin

Water found in ancient Moon rocks might have actually originated from the proto-Earth and even survived the Moon-forming event. Latest research into the amount...

New risk model sheds light on arsenic risk in China’s groundwater
