  • USGS Groundwater Model: New Tool for Communities in Northern and Central Arizona

    A new groundwater model of the interconnected aquifers in central and northern Arizona was released today by the U.S. Geological Survey, following a multi-year development effort that involved the Arizona Department of Water Resources and regional cooperators.  The computer model, known as the “Northern Arizona Regional Groundwater-Flow Model,” simulates how recharge from ...

  • Runoff research promotes healthier aquifers

    Where rain falls can influence the quality of surface water before it enters underground reservoirs, some of which provide water that eventually comes out of our taps. That's one conclusion from a collaborative study by the Agricultural Research Service (ARS) and the University of Arizona (UA). The ARS and UA scientists are investigating how urban landscapes influence storm runoff and water ...

  • Aquifer ph and enhanced reductive dechlorination

    The recent Battelle Memorial Institute symposium on bioremediation1 in Baltimore, MD featured a focused session of platform presentations on the timely topic of Bioremediation in Low-pH Aquifers. Throughout the session we heard a variety of case studies and viewpoints, with the primary focus of the session being biological reductive dechlorination of chlorinated ethenes (PCE, TCE, DCE and VC) in ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Potential of hydraulic fracturing fluids escaping to aquifers subject of new paper in Groundwater

    A recently published scientific paper offers a numerical study of the potential for fluids related to hydraulic fracturing to escape into usable aquifers via nearby abandoned wells. The article was published in National Ground Water Association’s flagship technical journal, Groundwater®. Titled “Influence of Hydraulic Fracturing on Overlying Aquifers in the Presence of Leaky ...

  • Developing Bioaugmentation Cultures for Chloroethene Remediation in Low pH Aquifers

    One of the major limitations for bioremediation of chlorinated ethenes in aquifers with a pH of approximately 6 and below is the perceived need to adjust the pH to the circumneutral range. This is based on numerous studies with Dehalococcoides and mixed cultures containing Dehalococcoides that indicate a steep reduction or cessation in cDCE and VC reduction to ethene at pH levels below 6. ...

  • Study: A third of global groundwater basins are overstressed

    Satellite data show people are overdrawing water from some of the world's largest groundwater basins. Researchers from the University of California, Irvine say it's unclear how much water is left in the most overburdened aquifers. The problem is expected to worsen with climate change and population growth. Using measurements taken by NASA's twin Grace satellites, scientists found the most ...

  • USGS study finds drinking water contaminated, but safe to drink

    A recent United States Geological Survey (USGS) study of public drinking water wells in California, Connecticut, Nebraska and Florida found that some were contaminated, but in amounts so minimal, human health was unlikely to be affected. The USGS tracked the movement of contaminants in groundwater and public-supply wells in four different aquifers.According to the USGS, wells are not equally ...


  • 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 finds mines can work for geothermal power

    Is there light at the end of the tunnel for mine shafts slated for closure? Two Spanish engineers say there is, noting that they could be the sites for geothermal energy providing power to towns that need it. Writing in the journal Renewable Energy, the researchers describe the tool that enabled them to estimate the amount of heat a tunnel could potentially offer industry and households. The ...

  • Study finds contaminants in California public-water supplies

    Nearly one-fifth of the raw groundwater used for public drinking water systems in California contains excessive levels of potentially toxic contaminants, according to a decade-long U.S. Geological Survey study that provides one of the first comprehensive looks at the health of California's public water supply and groundwater. One of the surprises in the study of 11,000 public supply wells ...

  • Laboratory study cuts fracking waste`s radioactivity

    Researchers believe they have found an unlikely way to decrease the radioactivity of some hydraulic fracturing wastewater: Mix it with the hazardous drainage from mining operations. The wastewater is created when some of the chemical-laced water used to fracture thick underground rocks flows back out of the wellbore. The water is tainted with chemicals, toxins and in some parts of the country - ...

  • 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 ...

  • Study: Rising Seas Slowed by Increasing Water on Land

    New measurements from a NASA satellite have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected the rate of sea level rise.
