  • 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 ...

  • 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 ...

  • Less and More: Why You Should Pump Slurries with a Peristaltic Pump

    LESS WATER Peristaltic Pumps Use Less Water Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 70 tonnes of ore per hour, ...

  • Report: Groundwater pumping in California has land sinking

    Vast areas of California's Central Valley are sinking faster than in the past as massive amounts of groundwater are pumped during the historic drought, state officials said, citing new research by NASA scientists. They said Wednesday that the data show the ground is sinking nearly two inches each month in some places, putting roads, bridges ...

  • Spanish earthquake could have been triggered by groundwater pumping

    An earthquake that killed nine people in Lorca, Spain, last year could have been triggered by groundwater being drained from the area for use in irrigation, according to scientists. The study found that the ground moved in the same places as subsidence has been occurring since the 1960s, due to the extraction of groundwater. In Europe, earthquakes are most common in southern and ...

  • Studies reveal why drinking water wells are vulnerable to contamination

    New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells. All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States receive ...

  • Study Assesses Threats to Groundwater Availability and Sustainability in Northern Atlantic Coastal Plain

    Scientists Look at Issue from Long Island to North Carolina Threats to groundwater availability and sustainability in the Northern Atlantic Coastal Plain are dependent to a large degree by the type of aquifers used for water supply, according to a new regional assessment by the U.S. Geological Survey. The water challenges ...

  • ACT leads the way on stormwater capture

    Yarram and Stratford farmers affected by falling groundwater levels in Victoria's Latrobe Aquifer will receive payments as part of a $5 million assistance package. The Latrobe Aquifer Financial Assistance Package includes $3.6 million from the Australian Government's Water for the Future plan and $1.4 million from the Victorian Government. Australian Government Parliamentary Secretary for Water ...

  • Wind power helps Texas town desalinate groundwater

    The first project in the United States to use wind power to desalinate drinking water for an inland municipality rather than a coastal town has just received a $500,000 grant from the Texas state Office of Rural Community Affairs, ORCA. The $1.075 million pilot project utilizing wind power to desalinate brackish groundwater in West Texas will be located in the small city of Seminole in Gaines ...

  • City of Phoenix wins Groundwater Supply Award from National Ground Water Association

    The City of Phoenix, Arizona, has received an Outstanding Groundwater Project Award from the National Ground Water Association for innovation and excellence in bolstering the city’s groundwater supply. This award will be presented during the 2013 NGWA Groundwater Expo and Annual Meeting taking place in Nashville, Tennessee. Based on the City of Phoenix’s 2010 groundwater management ...

  • Coordinated groundwater recharge needed

    The massive rains over California last month are not just a blessing but also a curse: a curse because the intensity of rain causes serious problems with flooding, erosion and landslides. Every watershed in California should therefore have a coordinated program to intentionally capture flood flows and recharge groundwater aquifers. Extreme weather is one reason so much reservoir storage has been ...


  • Scientists suggest alternative source of arsenic contamination

    New research contradicts previous findings that arsenic contamination — an environmental crisis that affects more than 60 million people in the Bengal Basin — in groundwater may result from arsenic coming from man-made ponds, suggesting instead that it originates in sediments in aquifers. Groundwater ...

  • EPA announces additional groundwater investigation at Delaware City PVC Superfund site

    The U.S. Environmental Protection Agency today announced a new investigation to determine the nature and extent of groundwater contamination at the Delaware City PVC Superfund site in New Castle County. Under an administrative settlement with the EPA, Bayer CropScience L.P. will investigate groundwater contamination in the shallow aquifer east of the PVC plant property and evaluate potential ...
