Tritium is a radioactive element found as a result of thermonuclear bomb testing during the 1950s.
Groundwater in a south Asia basin provides drinking and irrigation water for 750 million, but 60 percent of it is no longer usable.
The Chinese capital Beijing is sinking to the ground under the weight of its massive buildings and growing population.
After examining precipitation and groundwater data from wells scattered across the tropics, researchers discovered these freshwater resources may be more resilient to climate change than previously thought, and may even benefit from fewer but more intense rainfall patterns.
A new hybrid center pivot irrigation system sprays water above ground and pulls less water from underground, ultimately reducing the amount needed to grow potato crops.
Climate change, land use and population growth are threatening the availability of water sources in the Himalaya Mountain basins.
With heavier rainfall sweeping through the African savanna, one would expect to see more thriving populations of trees. However, it turns out trees' deep roots are actually disadvantageous and don't allow the plants to suck up abundant water resources.
Yale researchers have confirmed that removing natural gas from deep underground using hydraulic fracturing methods does not contaminate drinking water, although they also said that "geology across the country is very different."
After studying groundwater resources from the Illawarra plateau of New South Wales, researchers have developed water-tracing methods that will help detect future changes in water flow and quality.
The Tarim basin in China is a very dry region, home to rare trees and cotton farms that produce 40 percent of the nation's crop. However, this areas is facing significant ecological problems. Researchers suggest a series of recommendations in order to preserve this unique desert.
NASA recently compared satellite images of Earth's surface to see the effects of increased groundwater pumping. The profiles they found revealed that subsidence is occurring in the San Joaquin Valley at an increased rate.
One of the lightest elements, helium, has been thought to be dangerously near finished. Used in MRIs and the Large Hadron Collider, it's important. Researchers say it lies beneath mountain ranges, geyser fields, and is otherwise in supply in ways we didn't know as well before.
Researchers examined various snowpacks in the Sierra Nevada region in order to get a better understanding of how climate change is affecting subsurface water content levels.
A third of the Earth's biggest groundwater basins are in trouble, because after significantly relying on this hidden resource for so long, they are being quickly tapped out, according to two new studies.
No, Mars is not home to the massive ocean it once held. These days, most of its water is locked up in glaciers and large ice caps. Now, however, researchers think they have found signs that there is still some liquid water in the planet's soil, after finding evidence for liquid brine with NASA's Curiosity rover.
