DM Crumbliss for RedOrbit.com Groundwater is being used faster than it can be replenished in the High Plains states and in California´s Central Valley, according to a study published in the Proceedings of the National Academy of Sciences. Most of the water brought up in wells is used for irrigation in these vital agricultural regions. A new study based at the University of Texas finds that rapid depletion of groundwater is a threat to the country´s food supply. Scanlon and her...

Groundwater Pumping Leads To Sea Level Rise
2012-05-09 07:44:38

As people pump groundwater for irrigation, drinking water, and industrial uses, the water doesn´t just seep back into the ground – it also evaporates into the atmosphere, or runs off into rivers and canals, eventually emptying into the world´s oceans. This water adds up, and a new study calculates that by 2050, groundwater pumping will cause a global sea level rise of about 0.8 millimeters per year. “Other than ice on land, the excessive groundwater extractions are...

There is potential to store large volumes of Australia´s precious fresh water underground, to offset climate change, avoid evaporation losses and meet national water needs into the future, leading water scientists say. Following a major national scientific workshop in Canberra last week, researchers in the National Centre for Groundwater Research and Training (NCGRT) say that managed aquifer recharge — the injection or infiltration of excess surface water into underground...

100 Times More Groundwater In Africa Than Surface Water
2012-04-21 05:01:01

Researchers say they have created the most detailed map yet of groundwater across the entire continent of Africa. A group from the U.K. said they believe there is about 100 times the volume of water underground than there is on the surface of Africa. The team wrote in the journal Environmental Research Letters that they hope their map can improve access to water in Africa, where 300 million people are said to not have access to safe drinking water. Helen Bonsor, one of the authors of...
