  • 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 ...

  • Water map shows billions at risk

    About 80% of the world's population lives in areas where the freshwater supply is not secure, according to a new global analysis. Writing in the journal Nature, researchers have compiled a composite index of 'water threats' including issues such as scarcity and pollution. The most severe threat category encompasses 3.4 billion people. Vörösmarty et al. state that conserving water ...

  • Mapping groundwater flooding for the EU Floods Directive

    In the coming years the EU Floods Directive1 will require Member States to produce flood hazard and risk maps. Taking the UK as a case study, new research highlights the need for advances in data collection, mapping and groundwater flood warning systems to meet EU requirements for maps and management plans. Although often occurring less frequently than fluvial (river) flooding, the effects of ...

  • Geologists map rocks to soak CO2 from air

    To slow global warming, scientists are exploring ways to pull carbon dioxide from the air and safely lock it away. Trees already do this naturally through photosynthesis; now, in a new report, geologists have mapped large rock formations in the United States that can also absorb CO2, which they say might be artificially harnessed to do the task at a vastly increased pace. The report, by ...

  • 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 ...

  • Keynote speaker announced for the NGWA Conference on Hydrogeophysics and Deep Groundwater

    Andrea Croskrey, PG, from the Texas Water Development Board will give the keynote presentation, "Mapping Brackish Aquifers: Future Water Resources," at the  NGWA Conference on Hydrogeophysics and Deep Groundwater taking place March 20-21, 2017 in Denver, Colorado.  Croskrey has been mapping brackish aquifers in Texas as a member of the Brackish Resources Aquifer ...

  • 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 ...

  • 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 ...

  • Predicting the fate of underground carbon

    A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground carbon-dioxide reservoirs. One strategy for mitigating greenhouse gases is to inject compressed carbon dioxide into natural aquifers made of permeable rock soaked with brackish salt water. Carbon ...

  • Africa may struggle to extract groundwater, experts say

    Vast groundwater resources have been revealed in Africa by the first continent-wide quantitative maps. But the resources may not be easily accessible because of political and technical challenges and costs, say experts. The new groundwater maps, published last month (19 April) in Environmental Research Letters, are based on an extensive review of available maps, publications and data. They show ...

  • New study raises question: What don’t we know about water scarcity?

    A new study from the United States Geological Survey (USGS) reveals troubling news: The aquifers that millions of Americans rely on for freshwater are being depleted at an accelerating rate. In fact, aquifer depletion in the years between 2004 and 2008 was nearly triple the historical average. Population growth and increasing ...

  • NATION'S LARGEST SOURCE OF FRESH WATER - GROUND WATER - NEEDS MORE STUDY, NATIONAL GROUND WATER ASSOCIATION TELLS U.S. SENATE COMMITTEE

    In considering the nation's increasing demand for water, the federal government should support efforts to study the largest source of available fresh water - ground water, said the National Ground Water Association (NGWA) Tuesday in testimony before the U.S. ...

  • EPA to hold a public availability session regarding the capital city Plume Site, Montgomery, Alabama

    The U.S. Environmental Protection Agency (EPA) will hold a Public Availability Session on Thursday, November 3, 2011 regarding the Capital City Plume Site in Montgomery, AL. Representatives from EPA, the United States Geological Survey, the Alabama Department of Environmental Management, and the Agency for Toxic Substances and Disease Registry will be available to provide information and answer ...

  • Nine research papers on various topics featured in January-February issue of Groundwater

    If you’re a member of the NGWA Scientists and Engineers Section, you will soon receive the Groundwater January-February 2018 issue. Below is a brief overview of what you will find. In his Guest Editorial, Dylan J. Irvine encourages authors in Groundwater to share data, scripts, and spreadsheets with their readers to increase the ...

  • Fertilisers linked to contaminated drinking water in Evros, Greece

    In a new study, samples of drinking water from the north-east of Greece have been found to exceed European limits for nitrates, sulphates and phosphates - chemicals that are linked to health problems such as reproductive disorders and cancer. The research has produced a map of the Evros area showing the location of 64 water sampling sites and found that pollution levels are highest in areas with ...

  • AUD 7.5m boost to Australia’s groundwater management

    Minister for Climate Change and Water, Senator Penny Wong, this week announced funding of almost AUD 7.5 million from the National Groundwater Action Plan for three new projects to improve groundwater management in Australia.  “In a time of continuing drought and climate change, it’s vital that we improve our knowledge of Australia’s precious groundwater resources so that we can manage it ...

  • Groundwater development is not the answer for Africa

    Research showing the extent of Africa's significant groundwater reserves should not detract from the real challenges to meeting the continent's drinking water demands, argues Roger Calow, head of the Overseas Development Institute's Water Policy Programme. Recent research has found that Africa's groundwater resources — water found in non-renewable aquifers underground — are 100 times ...
