Limnology and Oceanography, Vol. 59, No. 5 (2014), pp. 1493-1509 (17 pages) We used δ15N-nitrate ( NO 3 − ) and δ 18 O-NO 3 − to unravel the provenance and fate of NO 3 − in a groundwater-fed estuary.

There is more to freshwater resources than meets the eye. While fresh water is visible in the form of rivers, lakes and glaciers, fresh groundwater resources — hidden beneath the Earth — often go ...

In an age when sustainable water sources are paramount, the IAEA has unveiled an ambitious strategy to delve deeper into groundwater research. The Agency's new coordinated research project (CRP) on ...

For many years scientists thought that groundwater — which hides in underground aquifers and slowly makes it way out to sea — wasn’t adding much to ocean chemistry. After all, groundwater only makes ...

Groundwater discharge flows through the sand on an Oahu beach. A global assessment found groundwater discharge plays a more significant role in ocean chemistry than had been thought. (Photo by Jenny ...

Researchers at Scripps Institution of Oceanography at UC San Diego have found that the water table in a San Diego aquifer system dropped by nearly 20 meters at the end of the last ice age. Groundwater ...

Rain and water in ponds and lakes slowly seeps into the soil, moving through minute cracks to refill underground aquifers. Per- and polyfluoroalkyl substances (PFAS), often described as forever ...

A study conducted by researchers at São Paulo State University (UNESP) in Brazil measured the contributions of rainwater and groundwater to the maintenance of springs and rivers in the vicinity of ...

BYU Professor of Geology, Greg Carling, and his team are investigating possible groundwater contamination in the Great Salt ...

Abnormal rises in groundwater levels after large earthquakes has been observed all over the world, but the cause has remained unknown due to a lack of comparative data before and after earthquakes.
