  • UNESCO publishes first world map of underground transboundary aquifers

    UNESCO is publishing the first-ever world map of shared aquifers to coincide with the submission to the General Assembly of the United Nations on 27 October of a draft Convention on Transboundary Aquifers. Almost 96% of the planet’s freshwater resources are to be found in underground aquifers, most of which straddle national boundaries. Despite its strategic importance, no global inventory of ...

  • Groundwater papers link methane in groundwater to natural sources

    A pair of papers in Groundwater®, NGWA's bimonthly technical publication, finds a high level of methane in water wells from two Texas counties is most likely from shallow natural gas deposits, not natural gas leaks caused by hydraulic fracturing operations in the underlying Barnett Shale.  The research builds on previous studies on well water quality in the Barnett Shale ...

  • 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 ...

  • US: Groundwater atlas

    The US Geological Survey series of publications “The Groundwater Atlas of the United States” describes the, location, extent and geological and hydrological characteristics of the nation’s important aquifers and is available online and in various print formats and scales. These have been produced over recent years as described in a useful summary fact sheet. Find out ...


  • Contaminants in US groundwater

    According to a new study by the USGS, more than 20% of untreated water samples from 932 public wells across the US contained at least one contaminant at levels of potential health concern. About one-third of the US population receive their drinking water from such a system. The USGS study (Contaminants in Groundwater used for ...


  • Treatment of abstracted groundwater

    Since abstracted groundwater can consist of a complex mixture of river bank filtrate and polder water, which have different origins and compositions, its treatment is challenging . An article in Drinking Water Engineering and Science discusses the effect of the properties of this mixture on the production of drinking water. In the Netherlands, over 60% of ...


  • Pesticide pollution slow to reach groundwater

    Underground water aquifers are a significant source of drinking water. In a recent study, French researchers found that pesticides applied to crops can take many years to sink down through the ground and reach groundwater. This means that they may still be entering aquifers, even after agricultural application has stopped. Groundwater is found underground in absorbent layers of rock. ...

  • 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 ...

  • Groundwater footprint reveals unsustainable water consumption

    Reservoirs of water stored under the earth’s surface, otherwise known as groundwater, are a valuable resource. However, using a footprinting method, a new global study has indicated that about 1.7 billion people live in areas where groundwater is being used more quickly than it can be replenished. Groundwater supplies water to billions of people and is important for agricultural ...

  • Existing and newly developed tools to assess groundwater shared at NGWA Hydrogeophysics and Deep Groundwater Conference

    The NGWA Hydrogeophysics and Deep Groundwater Conference was co-located with the Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP) March 20-21 in Denver, Colorado, where presentations shared the enhancements to existing tools and methods used to locate and assess groundwater resources as well as newly developed techniques. Several presentations focused ...

  • Strategy to assess the US`s groundwater availability

    Scientists proposed a strategy to study the Nation's ground-water supply as part of the Federal government's effort to help address the Nation's increasing competition for water. Declines in ground-water levels have led to concerns about the future availability of ground water, which provides half the country's drinking water and is essential to the vitality of agriculture and industry, as well ...

  • Groundwater Resources Generally Abundant in Coastal Carolinas

    Large volumes of high quality groundwater fill aquifers along the Atlantic Coastal Plain (ACP) in North and South Carolina. Groundwater levels in much of the region remain relatively unchanged from predevelopment days, despite declines in some locations from large-scale pumping. These are among the key findings of a major federal study, conducted by the U.S. Geological Survey, to assess the ...

  • Site`s groundwater, soil cleanup working

    The effort to clean up soil and groundwater contamination at the nation's only plant for assembling and disassembling nuclear weapons has been effective so far and will continue for years, according to the first five-year review of the site. Pantex in the Texas Panhandle was added to the national Superfund cleanup list in 1994 because of past site practices that included burning chemicals in ...

  • Groundwater monitoring: what’s winter field work like?

    Although the stimulation phase of the Newberry EGS Demonstration has come to a close, field work continues throughout the winter months on the volcano (brrr!). We’re currently collecting and analyzing groundwater samples in order to monitor any changes in the local groundwater system. This work is intended to make sure thestimulation hasn’t affected the quality of the groundwater high ...

  • NASA data reveal major groundwater loss in California

    In research being presented this week at the American Geophysical Union meeting in San Francisco, scientists from NASA and the University of California, Irvine, detailed California's groundwater changes and outlined Grace-based research on other global aquifers. The twin Grace satellites monitor tiny month-to-month changes in Earth's gravity field primarily caused by the movement of water in ...


  • NGWA grants Groundwater Supply Award for Baton Rouge project

    Layne Christensen Co. and Owen and White Consulting Engineers Inc. have received an Outstanding Groundwater Project Award from the National Ground Water Association for outstanding engineering and innovation in supplying groundwater. This award will be presented during the 2015 Groundwater Expo taking place in Las Vegas, Nevada, December 15-17. Layne Christensen of Bloomington, Indiana, and Owen ...

  • Climate change could affect groundwater recharge, scientists say

    (AXcess News) Washington - Elevated levels of carbon dioxide (CO2) in the Earth's atmosphere could seriously impact air, weather and vegetation. Now a scientist with the Agricultural Research Service (ARS) is taking a closer look at what could happen underground. If atmospheric CO2 levels double within this century, as many climate models predict, some areas could experience large increases in ...

  • EPA reaches cleanup decision for J1 range and groundwater plumes at Camp Edwards

    As efforts to clean up and protect Cape Cod's drinking water continue, the EPA and the Commonwealth of Massachusetts have reached another cleanup decision regarding a former military training and contractor testing area at Camp Edwards on the Massachusetts Military Reservation (MMR). This decision marks a final cleanup strategy for MMR’s J1 Range and its two affiliated “northern and ...

  • EOS selected as bioremediation product for massive Indiana TCE groundwater plume

    Past use of tricholoroethene (TCE) at a manufacturing facility in Indiana created a contaminated plume of groundwater approximately 1,000 feet wide, 8,000 feet long, and up to 75 feet deep.  The plume has impacted a regionally significant unconfined aquifer.  EOS 598B42 emulsified oil product was the selected electron donor for the bioaugmentation pilot test that was completed at the ...
