  • A standard method of publishing and sharing scientific data

    A standard method for publishing different types of data generated from environmental observations has been developed. It allows researchers to publish data from many different sources so that they are freely available, can be easily understood, and can be integrated with observational data from other sources. Scientific research is generating more information than ever before. Although ...

  • Paper cautions against oversimplified interpretation of GRACE groundwater data

    NASA’s Gravity Recovery and Climate Experiment (GRACE) has provided useful information about global groundwater depletion, but insufficient attention has been placed on its limitations, concludes a paper published in Groundwater®, a journal of the National Ground Water Association. Authored by Dr. William M. Alley, NGWA’s director of science and technology, and Dr. Leonard F. ...

  • Swathe of new EU green laws published

    A series of new EU environmental rules were published in the official journal in late December, triggering their entry into force. Directive 2006/118/EC on the protection of groundwater from pollution requires that by 22 December 2008, member states establish threshold safety values for substances including mercury, ammonium, and lead.  It also imposes a single limit value of 50 milligrams per ...

  • Special issue of Groundwater Monitoring & Remediation focuses on agricultural impacts to groundwater quality

    The National Ground Water Association’s technical journal,Groundwater Monitoring & Remediation®, has published a special issue focusing on the monitoring and remediation of agricultural impacts to groundwater quality. Agricultural land use represents the largest nonpoint source threat to groundwater quality on a global scale. As a result of decades of fertilizer application and ...

  • New map of global groundwater depths

    Despite groundwater’s importance to ecosystems, little is known about its global distribution. Researchers have now developed a model to map groundwater, revealing that ecosystems covering 22-32% of the Earth’s surface rely on this important resource. Groundwater is vital for many ecosystems, providing crucial support to plants and animals, especially during droughts. ...

  • Encouraging results in evaluating groundwater contaminants

    The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation’s groundwater. The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the ...

  • 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 ...

  • Making the most of Africa´s scarce groundwater resources

    Understanding the impact of climate change and development on groundwater resources in Africa is the theme of a conference opening this week in Kampala, Uganda. In a continent already facing water scarcity, phenomena such as climate change and rapid population growth are expected to force local populations to increase their reliance on groundwater resources to meet domestic, agricultural and ...

  • Scientists develop improved groundwater forecasting model

    Scientists in India have developed a more efficient computing model to predict monthly changes in groundwater, which is depleted in many areas of developing countries because of damaged soils and poor irrigation practices. A team of scientists based in India's four southern states used the concept of an 'artificial neural network' (ANN), a computing technique that mimics the way millions of ...

  • Scotland’s water and groundwater quality improving, says SEPA

    Water quality in Scotland is good and continues to improve. That's according to the recently published Scotland’s Water Environment Review 2000-2006 featuring water quality classification data that illustrates historical trends stretching back over the past six years.  The review, which has been published by the Scottish Environment Protection Agency (SEPA), is a valuable source of environmental ...

  • 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 ...

  • Vital groundwater depleted faster than ever

    China, the world’s most populous country, doubled within just 10 years its use of irreplaceable groundwater from underground reservoirs that are replenished more slowly than they are drained. And in the same decade, 2000 to 2010, global use of this non-renewable water resource for irrigation increased by a quarter, according to a  ...

  • Parched Emirates relies on sea as groundwater runs out

    As skyscrapers and gleaming towers rose with lightning speed across the United Arab Emirates over the past two decades, the Gulf nation's thirst for water grew at an enormous rate - so much so that today, it threatens to dry up all of the country's groundwater in as little as 15 years, experts say. To quench that demand, cities across the seven emirates that make up the UAE rely on desalinated ...

  • Nitrate concentrations of groundwater increasing in many areas of US

    Nitrate is the most common chemical contaminant in the world’s ground water, including in aquifers used for drinking-water supply. Nitrate in drinking water of the United States is regulated by the U.S. Environmental Protection Agency (USEPA) because of concerns related to infant health and possible cancer risks. Use of man-made synthetic fertilizers has steadily increased since World War II, ...

  • ARCADIS scientists co-author 3rd edition of Groundwater Treatment Technology

    ARCADIS (EURONEXT: ARCAD), the international consulting and engineering company, today announced that Evan K. Nyer, along with a team of other ARCADIS engineers and scientists, have co-authored the third edition of Groundwater Treatment Technology, which was published in January 2009 by Wiley. The first edition, by Mr. Nyer, originally came out in 1986. Groundwater Treatment Technology has been ...

  • 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 ...

  • Historic groundwater forum in India in the midst of severe drought in South Asia

  • Satellites unlock secret to northern India`s vanishing water

    Using satellite data, UC Irvine and NASA hydrologists have found that groundwater beneath northern India has been receding by as much as 1 foot per year over the past decade – and they believe human consumption is almost entirely to blame.More than 109 cubic kilometers (26 cubic miles) of groundwater disappeared from the region's aquifers between 2002 and 2008 – double the capacity of India's ...
