Bridgeton, New Jersey over troubled water: Waning supply may force city to halt connections

Posted By kevinthemann in Hydrogeology

The wells have essentially run dry in this city, and officials here are considering putting a moratorium on new water connections until infrastructure improvements to increase pumping capacity - estimated to take as long as 18 months - are put into place.
John Wuzzardo, the city's water superintendent, said Friday that City Council is expected to again discuss the waning water supply at a specia http://www.pressofatlanticcity.com -

Unsustainable water withdrawals for irrigation

Posted By Ryan13 in Planning and Management

The imbalance in long-term water budgets necessitates diversion of surface water or the tapping of groundwater resources. The areas shown with moderate-to-high levels of unsustainable use occur over each continent and are known to be areas of aquifer mining or major water transfer schemes. http://maps.grida.no -

Southwest Hydrology, Volume 7, Number 3: Aquifer Recharge, Storage, and Recovery

Posted By Kaveh in Hydrogeology

In this issue we define the deliberate recharge and temporary storage of “excess” (unneeded) water in an aquifer, with the intent of recovering that water for future use, as aquifer storage and recovery (ASR). The technique is increasingly being used as a water management tool. The implementation of ASR projects varies widely in the type of water used, method of recharge, aquifer type, and engine http://www.swhydro.arizona.edu -

Water crisis to be biggest world risk

Posted By goopsgoops in Planning and Management

A catastrophic water shortage could prove an even bigger threat to mankind this century than soaring food prices and the relentless exhaustion of energy reserves, according to a panel of global experts at the Goldman Sachs "Top Five Risks" conference. Water is not a renewable resource. People have been mining it without restraint because it has not been priced properly. Underground aquifers could http://www.telegraph.co.uk -

Falling and Failing Aquifers

Posted By goopsgoops in Hydrogeology

the U.S. Department of Agriculture (USDA) reports that in parts of Texas, Oklahoma, and Kansas--three leading grain-producing states--the underground water table has dropped by more than 30 meters (100 feet). As a result, wells have gone dry on thousands of farms in the southern Great Plains, forcing farmers to return to lower-yielding dryland farming. Although this mining of underground water is http://aguanomics.com -

Estimating hydraulic properties of coastal aquifers using wave setup

Posted By dane307 in Fluid Mechanics

Wave setup is the elevated mean water-table at the coast associated with the momentum transfer of wave breaking, which occurs generally over several days. Groundwater responses to wave setup were observed as far as 5 km inland in central Maui, Hawaii. The analysis showed that at times of energetic swell events wave-driven water-table overheights dominate low-frequency groundwater fluctuations ass http://www.sciencedirect.com -

Technology to help fight aquifer salinity

Posted By Ryan13 in Hydrogeology

DOHA • Qatar Science & Technology Park (QSTP) and Texas A&M at Qatar (TAMUQ) are to launch a $400,000 project to overcome a major environmental impact of water desalination.

The Zero Liquid Discharge (ZLD) technology will replace the brine that normally remains from desalination plants with easily-disposable solids. Qatar's farms should be among the first to benefit. As seawater intrudes into http://www.thepeninsulaqatar.com -
