World Groundwater Recharge Map

Posted By aqua in Hydrogeology

Territory size shows the proportion of worldwide groundwater recharge occurring there.

Regionally South America has the most groundwater recharge. The lowest is in Japan.

Groundwater is water that has infiltrated rocks, and moved deep into the ground. Groundwater usually travels through permeable rocks, and sometimes forms underground rivers. Nearly 70% of all freshwater is groundwater, mak -

Report: Ground-Water Availability in the United States

Posted By aqua in Hydrogeology

Ground water is among the Nation's most important natural resources. It provides half our drinking water and is essential to the vitality of agriculture and industry, as well as to the health of rivers, wetlands, and estuaries throughout the country. Large-scale development of ground-water resources with accompanying declines in ground-water levels and other effects of pumping has led to concerns -

Groundwater: the neglected resource

Posted By kevinthemann in Hydrogeology

Ground water is a neglected resource from both a quality and quantity perspective. Often, we don't worry excessively about how much of it we can extract before the loss becomes apparent. Collectively, we worry less about how usable the water is until something untoward happens (as in the case of groundwater contamination in Love Canal, NY, now 30 years ago and Hinkley, CA, the setting for Erin B -

Water research worries drillers, ranchers

Posted By teddyRIO in Water Quality

A paper published by University of Wyoming researchers has some oil and gas companies in the Powder River Basin worried about water discharge permits and some Wyoming ranchers worried the water they have been using for years will no longer be considered safe for livestock to drink.

The UW bulletin summarizes how 11 common contaminants found in ground water are metabolized by livestock and wild -

WaterWired: Deep Ground Water, Desalination, and Unintended Consequences: Water Policy Vacuum

Posted By teddyRIO in Hydrogeology

Just when I was wondering what to post today, John Fleck sent me this link to a 16 August 2008 Albuquerque Journal editorial about pumping and desalting deep ground water.

The sage folks at the Journal have done us all a service, exposing a flaw in New Mexico water policy (and those of other Western states, no doubt): what do you do about the pumping of deep ground water that, because of its -

Strategy to Assess the Nations Ground-Water Availability

Posted By Waterlover in Hydrogeology

Scientists proposed a strategy to study the USA's ground-water supply as part of the Federal government's effort to help address the USA's increasing competition for water. Declines in ground-water levels have led to concerns about the future availability of ground water, which provides half the country's drinking water and is essential to the vitality of agriculture and industry, as well as to t -
