  • High resolution multi-level monitoring for bedrock aquifers

    This presentation describes a comprehensive approach for determining the nature, extent, transport and fate of contaminants at industrial sites on fractured rock, with emphasis on sedimentary rock, referred to as the Discrete Fracture Network (DFN) approach. Development of this DFN approach began at a sandstone site in California in 1997, where the initial version of a method for measuring ...

  • Idaho aquifer decline could hinder radioactive monitoring

    A continued drop in underground water levels could make it more difficult to monitor the movement of radioactive contamination in an aquifer below an eastern Idaho nuclear facility, scientists say. Researchers with the U.S. Geological Survey in a 36-page report released Monday said the Eastern Snake River Plain Aquifer level has dropped below ...

  • Technical Announcement: Bacteria No Match for Deep Floridan Aquifer

    A first of its kind study has the potential to impact future regulatory decisions on disinfection practices for water prior to its recharge or following its storage in the Floridan Aquifer. The U.S Geological Survey report found that coliform bacteria die off faster in a regional aquifer system ...

  • California authorizes oilfield dumping into protected aquifers

    Regulators in California, the country's third-largest oil-producing state, have authorized oil companies to inject production fluids and waste into what are now federally protected aquifers more than 2,500 times, risking contamination of underground water supplies that could be used for drinking water or irrigation, state records show. While some of the permits go back decades, an Associated ...

  • OS Remediation Invites You To A Webinar: Fate of Vinyl Chloride in Aquifers: Organisms, Pathways, and Monitoring Tools

    As a proven human carcinogen, vinyl chloride (VC) is a major risk factor in many contaminated aquifers.  Lingering concentrations above the maximum concentration level (MCL) of 2 ppb generally prevent site closures, thus requiring continued remedial and monitoring efforts.  Knowledge of the pathways and mechanisms that contribute to VC detoxification is essential to predict the fate and ...

  • NGWA publishes best practices for groundwater professionals on aquifer storage and recovery

    A new set of best suggested practices (BSPs) for groundwater professionals involved in aquifer storage and recovery (ASR) projects has been approved by the National Ground Water Association (NGWA). First conceptualized in 2010, NGWA’s Best Suggested Practices for Aquifer Storage and Recovery has been developed through consensus of industry professionals with day-to-day experience in ASR ...

  • ISMAR7, the premier event for aquifer management, is now accepting abstracts.

    Recognized as the world's pre-eminent conference devoted entirely to aquifer recharge, this event offers you access to the latest scientific advances, project case histories, and technological innovations in Managed Aquifer Recharge (MAR). ISMAR7 (the seventh in the conference series) will be held in Abu Dhabi, October 9 - 13, 2010 at the Armed Forces Officers Club (AFOC). ...


  • Study: Two major U.S. aquifers contaminated by natural uranium

    Nearly 2 million people throughout the Great Plains and California live above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of Nebraska-Lincoln. Data from roughly 275,000 groundwater samples in the High Plains and Central Valley aquifers show that many Americans live less than two-thirds of a mile from ...


  • GAF AG to conclude AQUIFER project on African transboundary water management supported by Earth observation

    GAF AG, an internationally active geo-information technology company located in Munich, Germany, today announces the upcoming completion of the AQUIFER project. The final workshop will take place in Tunis at the beginning of September 2007. AQUIFER is one of the demonstrator projects of ESA's 'Earth observation for Integrated Water Resources Management in Africa' initiative, known as TIGER and ...

  • EPA issues permit associated with aquifer pump test at weld county (Colo.) uranium site

    The U.S. Environmental Protection Agency has issued an injection well permit to Powertech, (USA) Inc. that will enable the company to re-inject groundwater from an aquifer pump test at the proposed Centennial uranium site in Weld County, Colorado. This Underground Injection Control (UIC) Class V permit does not allow any uranium recovery activity at the site. The permitted activity is limited ...

  • The capillary fringe: monitoring and remediation in this neglected zone

    Much of the capillary fringe is fully-water-saturated but water is held under negative pressure. Dissolved contaminants migrate laterally as under the water table and residual LNAPLs such as gasoline occur in the capillary fringe. This is becoming more significant as ethanol-blended gasoline may be released into the subsurface. The behavior of ethanol fuels in the subsurface will highlight recent ...

  • Water monitoring and treatment technologies gain traction as potable water resources Diminish, finds Frost & Sullivan

    Groundwater is contained in rocks that are known as aquifers. Aided by gravity, the water fills the aquifer from the bottom upwards. The lower part of the aquifer has spaces that are completely filled by water. These are termed as the 'saturated zone' of the aquifer. In the top part of the aquifer, the rock spaces contain air as well as water. This part of the aquifer is called 'unsaturated'. ...
