  • 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. ...

  • 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 ...

  • New Map Shows How Groundwater Pumping Could Affect the Malad River

    A new report illustrates how groundwater pumping can affect the amount of water available in streams within the Malad-Lower Bear River Area in Utah. The product was developed by the U.S. Geological Survey, in cooperation with the Utah Department of Natural Resources, Division of Water Rights. “The information from this study will be used to aid the state engineer in making ...

  • Mapping pesticide contamination risk

    A new computerised tool helps regulators identify water sources at risk of pesticide contamination. The tool can be used to produce maps indicating water bodies at risk of contamination by taking into account: adjacent land-use, the concentration of pesticides in the environment and biological indicators of contamination. Protection of water resources is a key priority for the EU and water bodies ...

  • Groundwater evaluation platform

    SuperGeo Technologies has developed a data platform for groundwater recharge areas in order to evaluate the recharge potential. The platform is able to assist researchers in delimiting groundwater recharge areas and also in determining parameters such as recharge rate, pumping rate, flow rate and recharge potential. Water resource protection is one of the most important policies in Taiwan. ...

  • 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 ...

  • Genes and GPS used to map spread of typhoid

    A combination of geographic and genetic data is showing how typhoid fever spreads, and could be used for mapping other disease patterns, a study has reported. Researchers used DNA sequencing, global positioning system (GPS) and Google Earth technologies to track typhoid transmission in Kathmandu, the rapidly growing capital city of Nepal, where thousands fall ill with typhoid fever each year. ...

  • Integrating groundwater science and human wellbeing

    The thirty-sixth Congress of IAH has just drawn to a successful conclusion at Toyama in Japan. Some four hundred delegates, drawn more or less equally from within and outside Japan were warmly welcomed to the city by Takakazu Ishii, the Governor of Toyama Prefecture. After two days of technical sessions of presentations and posters in the excellently-appointed conference centre, the participants ...

  • Kenya homes in on emergency groundwater supplies

    A project that will map groundwater resources in part of the drought-prone Horn of Africa region was launched in Nairobi, Kenya, last week (22 May). It will use remote sensing technology to explore underground ...

  • Determining the good status of groundwater in the EU

    Groundwater standards in Member States are to be established by the end of 2008, according to the European Union's new Groundwater Directive. Recent research has developed a new method to determine the chemical status of groundwater which is applicable across the EU. This procedure has been assessed by testing the quality of the groundwater of the Upper Rhine Valley in Germany, Switzerland and ...

  • ZZ conducted pollution mapping (sulphur) IP survey in Brukunga, South Australia

    ZZ participated in pollution mapping at an abandoned mine site in South Australia. The scope of the survey is to find the sulphur development direction, so preventive method could be used to stop the sulphur get into the groundwater.  Over 9 survey lines were laid in two days to cover the survey area. On site drillings were followed up after the resistivity survey and concurred with our ...

  • 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 quality and wastewater treatment — WISE interactive maps updated

    A series of maps on water quality, updated with the latest information reported by countries, has been published by the European Environment Agency (EEA). The maps display water quality parameters in various receiving waters across Europe, alongside information on urban wastewater treatment and receiving areas sensitive to eutrophication. The updated maps are useful for water professionals who ...

  • 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 ...

  • Victorian Groundwater Management System Direct Input to ESdat

    The Victorian groundwater management system (GMS) is a database of groundwater related data (for example groundwater, geology or chemistry data) across Victoria that is delivered quarterly by DVD from the Department of Sustainability and Environment to registered subscribers. The delivery of data from this system is often in a format that is time-consuming to extract, filter and output as useful ...

  • 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 ...
