Emerald Bay, California, a beautiful location on the southwestern shore of Lake Tahoe, is surrounded by rugged landscape, including rocky cliffs and remnants of...

Western droughts caused permanent loss to major California groundwater source

California's Central Valley aquifer, the major source of groundwater in the region, suffered permanent loss of capacity during the drought experienced in the area...

Scientists use satellites to measure vital underground water resources

The availability of water from underground aquifers is vital to the basic needs of more than 1.5 billion people worldwide, including those of us...

Argonne’s powerful X-rays key to confirming water source deep below Earth’s...

A study published in Science last week relies on extremely bright X-ray beams from the U.S. Department of Energy's (DOE) Advanced Photon Source (APS)...

West Virginia groundwater not affected by fracking, but surface water is

Fracking has not contaminated groundwater in northwestern West Virginia, but accidental spills of fracking wastewater may pose a threat to surface water in the...

As sea level rises, much of Honolulu and Waikiki vulnerable to...

New research from the University of Hawai'i at Manoa (UHM) reveals a large part of the heavily urbanized area of Honolulu and Waikiki, Hawai'i...

Legends of the lost reservoirs

Tucked away in a laboratory in University of Cincinnati's Braunstein Hall are tubes of rock and dirt that quietly tell a story—a story that...

Deep groundwater aquifers respond rapidly to climate variability

Changes in climate can rapidly impact even the deepest freshwater aquifers according to Penn State and Columbia University hydrologists. The researchers found that responses to...

Groundwater helium level could signal potential risk of earthquake

Japanese researchers have revealed a relationship between helium levels in groundwater and the amount of stress exerted on inner rock layers of the earth,...

Study links groundwater changes to fracking

A new study has found heightened concentrations of some common substances in drinking water near sites where hydraulic fracturing has taken place. The substances...

New maps reveal safe locations for wastewater injection

Stanford geophysicists have compiled the most detailed maps yet of the geologic forces controlling the locations, types and magnitudes of earthquakes in Texas and...

Researchers have uncovered previously hidden sources of ocean pollution

Researchers have uncovered previously hidden sources of ocean pollution along more than 20 percent of America's coastlines. The study, published online Aug. 4 in the...

Can fluids from fracking escape into groundwater

A new study looks at how fluids related to hydraulic fracturing or "fracking" can escape into aquifers via nearby leaky abandoned wells. This could lead...

How much does groundwater contribute to sea level rise?

Groundwater extraction and other land water contribute about three times less to sea level rise than previous estimates, according to a new study published...

Groundwater quality changes alongside expansion of hydraulic fracturing

New research from The University of Texas at Arlington demonstrates that groundwater quality changes alongside the expansion of horizontal drilling and hydraulic fracturing but...

Test aims to identify shale gas hazard in groundwater

A test has been developed to check for contamination of shallow groundwater from unconventional gas extraction techniques, such as fracking. The development could help monitor...

Storing Extra Surface Water Boosts Groundwater Supply During Droughts

Although years of drought and over-pumping have significantly depleted groundwater in Arizona and California, a new study shows the situation has an upside: It...

How Climate Change Will Affect Western Groundwater

By 2050, climate change will increase the groundwater deficit even more for four economically important aquifers in the Western U.S., reports a University of...

Ground water storage helped offset sea level rise, study says

Recent increases in the storage of excess groundwater may be helping to offset sea level rise by as much as 22%, a new study...
