Proposed bill would enable desert-killing groundwater exploitation
After failing several times to win approval for a new groundwater depletion scheme via regulatory channels, the Southern Nevada Water Authority is now pursuing a legislative water grab that could devastate fragile desert ecosystems and push some endangered species even closer to extinction.
Most recently, the Nevada Supreme Court rejected the Las Vegas bid for a new pipeline.
Assembly Bill 298 would enable for groundwater export projects that would harm prings and wetlands, degrade air quality with fugitive dust and impact existing water rights holders. During the hearing numerous members of conservation groups and the public spoke to vigorously oppose the bill. Continue reading “Thirsty Las Vegas pushes legislative water grab”→
New research ranks world’s most threatened aquifers
FRISCO — Scientists this week said that many parts of the world are using groundwater at an unsustainable rate, without any clear idea about when the water might run out. The most overburdened aquifers are in the world’s driest areas, which draw heavily on underground water. Climate change and population growth are expected to intensify the problem.
After studying the world’s 37 largest aquifers, the research team said the Arabian Aquifer System, an important water source for more than 60 million people, is the most overstressed in the world. The Indus Basin aquifer of northwestern India and Pakistan is the second-most overstressed, and the Murzuk-Djado Basin in northern Africa is third.

Satellite data suggests more than 75 percent of water loss in drought-stricken basin is from groundwater pumping
By Summit Voice
FRISCO — Groundwater pumping is a huge factor in the Colorado River Basin water equation, California-based researchers said this week, announcing the results of satellite study that for the first time quantifies how groundwater contributes to the water needs of western states.
Along with surface diversions and pipelines, water users in the basin are also unsustainably depleting underground aquifers. For example, mountain resort towns in Colorado tap underground water from headwaters streams like Tenmile Creek and the Blue River for municipal use.
Study also correlates aquifer withdrawals with activity on San Andreas Fault
FRISCO —After crunching the numbers from a global earth-monitoring network, University of Nevada, Reno scientists day rapid depletion of groundwater in California’s Central Valley is accelerating uplift of the Sierra Nevada Mountains.
