The groundwater contained in aquifers is one of the most important sources of water on Earth: About 30 percent of our liquid freshwater is groundwater, according to the National Oceanic and ...

The greater Los Angeles area has long been the subject of intense seismographic monitoring. A network of highly sensitive seismometers peppers the region on a constant vigil for earthquakes.

Approximately 80 percent of the Ogallala Aquifer lies to the west of the proposed alignment, “uphill” of the pipeline’s route. Spilled oil could not move upward against gravity. 2.

Holocene aquifers are the source ... Map of the Hanoi ... The magnitude and direction of the head gradient within the 25–30-m depth of the aquifer at Van Phuc was calculated using the ...

Scientists using seismic data tracked groundwater levels beneath the L.A. area. They found heavy rains in 2023 boosted shallow waters, but deep aquifers remain depleted.

Farmers are emptying some of the world's most important aquifers faster than rainfall can replenish them, which means less water for everyone. This map from the journal Nature shows where ...

Jane Kleeb is a savvy activist who, Nebraska’s Republican governor once said, “has a tendency to shoot her mouth off most days.” A Florida native who moved to Nebraska in 2007 after marrying ...

This first national assessment of fracking focused on well depth raises particular concerns about fracking wells less than a mile deep (Environ. Sci. Technol . 2015, DOI: 10.1021/acs.est.5b01228 ).

In most years, aquifers recharge as rainfall and streamflow seep into unpaved ground. But during drought the water table—the depth at which water is found below the surface—drops as water is ...

The UNESCO map merely helps define the geographical extent of an aquifer, which could be useful in defining international agreements. The map could also help countries better manage their water.
