Two thirds of USA struggling with water shortages, drought

The worst drought in more than half a century baked more than two thirds of the continental United States this summer and its harsh effects continue to plague the parched cities and towns of the Great Plains. Ask the 94,000 people of San Angelo, Texas who are running out of water. Fast.

Agriculture depleting global ground water reserves

The world is depleting underground water reserves faster than they can be replenished due to over-exploitation, according to scientists in Canada and the Netherlands. The researchers, from McGill University in Montreal and Utrecht University in the Netherlands, combined groundwater usage data from around the globe with computer models of underground water resources to come up […]

Huge Ground Water Reserves in Africa

London – Huge reserves of underground water in some of the driest parts of Africa could provide a buffer against the effects of climate change for years to come, scientists said on Friday. Researchers from the British Geological Survey and University College London have for the first time mapped the aquifers, or groundwater, across the […]

Southern Africa: Improvements to regional groundwater management

With a view to improving development and management of groundwater in the region, the Southern African Development Community (SADC) is developing several tools to empower persons and organisations involved in the management of groundwater in southern Africa. Groundwater is likely to play an even greater role for human development under changing climatic conditions hence the […]

More Valuable than Gold

GROUNDWATER Where does it come from? Groundwater is an important part of the water cycle. It comes from rain, snow, sleet and hail that soak into the ground. The water moves down into the ground because of gravity, passing between particles of soil, sand, gravel, or rock, until it reaches a depth where the ground […]

Groundwater to play a key role in South Africa – Water Research Commission

The use of groundwater, in conjunction with surface water, could form a key part of the solution to South Africa’s water crisis, the Water Research Commission (WRC) said on Tuesday, which marks World Water Day. WRC water research manager Dr Shafick Adams said the total volume of available, renewable groundwater in South Africa is 10,34-billion […]

The World’s Oldest Water?

New evidence bolsters the notion that deep saline groundwaters in South Africa’s Witwatersrand Basin may have remained isolated for many thousands, perhaps even millions, of years. The study, recently accepted for publication in Chemical Geology, found the noble gas neon dissolved in water in three-kilometre deep crevices. The unusual neon profile, along with the high […]

DA calls for moratorium on Karoo gas exploration

A controversial application by oil giant Shell to explore for gas in an area of the Karoo should be put on hold, the Democratic Alliance said on Tuesday. The opposition party warned that exploration would involve processes that risked contaminating surrounding bodies of water, but Shell countered that processes were in place to prevent this […]

Groundwater Overuse May Make Arsenic More Common in South Asian Wells

A century of exploitation of groundwater supplies has drawn down water tables across Vietnam, making it difficult to avoid water contaminated with arsenic even at deeper depths, according to a new study. In tests of 512 private wells reaching depths of 10 to 50 meters (33 to 164 feet), researchers found that 27 percent contained […]
