  • Sophisticated monitoring array to address mystery of uranium plume

    Scientists have been puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists. Now, an innovative system has been installed for field experiments to better understand this complex site and to support future cleanup ...

  • ASTM D6429 - 99(2011)e1 standard guide for selecting surface geophysical methods

    This guide applies to commonly used surface geophysical methods for those applications listed in Table 1. The rating system used in Table 1 is based upon the ability of each method to produce results under average field conditions when compared to other methods applied to the same application. An “A” rating implies a preferred method and a “B” rating implies an alternate ...

  • Melting polar ice-caps could bring more droughts to Africa

    Sudden changes in the African monsoon can have large-scale socio-economic effects on fragile economies that depend on moisture for agriculture and basic human needs. New research has predicted that the impact of changes in the ocean's currents as a result of melting polar ice-caps could reduce rainfall during the monsoon in Africa leading to more droughts. Data suggest that droughts as a result ...

  • 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 ...

  • Groundwater movement and contaminant transport in the Earth’s subsurface are the focus of two 2017 Darcy lectures

    Quantifying water movement and contaminant transport in the Earth’s subsurface are the critical issues addressed during presentations offered through the 2017 Henry Darcy Distinguished Lecture Series in Groundwater Science. Earth’s subsurface is part of the “critical zone” — the layer of the planet from the tops of the trees to the bottom of groundwater. This zone is ...

  • Toxic chemicals hindering the recovery of Britain`s rivers

    Toxic chemicals from past decades could be hindering the recovery of Britain's urban rivers, concludes a recent study by scientists from Cardiff University, the University of Exeter, and the Centre for Ecology and Hydrology. During the 1970s, over 70% of the rivers in the South Wales valleys were classified as grossly polluted, by a combination of poor sewage treatment, colliery waste and ...

  • WEFTEC ® Now the Largest Annual Water Quality Exhibition in the World

    Alexandria, Va. - WEFTEC® .06, the Water Environment Federation’s 79th annual technical exhibition and conference, hosted 17,632 attendees and a record 965 companies using 245,155 square feet of floor space last week in Dallas, Texas, officially designating WEFTEC as the largest annual water quality exhibition in the world. 'The core of WEF’s mission and the reason it was created over ...

  • 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 ...

  • Fertilize the ocean, cool the planet?

    Original story at MIT News Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species also release dimethyl ...

  • National Ground Water Research and Educational Foundation awards research grants

    The National Ground Water Research and Educational Foundation has awarded grants totaling $15,895 for two research projects, one exploring emerging contaminants and the other groundwater/stream water interactions. “Aquifer Storage and Recovery of Recycled Water: Identifying Emerging Contaminants in Source Water and Examining Their Fate and Transport” addresses a key priority ...

  • Climate change and the Thames Estuary

    Critical research findings that will help plan future flood risk in the Thames Estuary were revealed recently as part of the Environment Agency’s Thames Estuary 2100 Project — a project that considers an adaptive approach for planning for future flood risk in the Estuary. The results, released at the international conference Climate change impacts and adaptation: Dangerous rates of change at ...

  • Tracking the UK`s carbon from soil to sea

    This January scientists from a range of disciplines will come together to undertake the first ever coordinated sampling of the major rivers in Great Britain to look for soil derived organic carbon. This carbon is a large element of our 'natural capital' - in fact it is so large that restoring some damaged elements of it, such as upland peat bogs, could cost up to £570 million over the next ...

  • Northern US soil carbon reservoirs vulnerable to global warming, says USGS

    Mounting evidence shows that soil carbon is increasingly contributing larger amounts of carbon dioxide (CO2) to the atmosphere as a result of warming, permafrost degradation, and complex climate-biogeochemical interactions. Northern soils are known to harbor large amounts of carbon in the zone between the moss surface and the permafrost or mineral soil boundary. USGS Soil Scientist, Jennifer ...

  • Restoring coastal wetlands? check the soil

    Rising sea levels and coastal development are threatening coastal freshwater wetlands with saltwater intrusion. While most ecosystem restoration projects have focused on surface water and groundwater, new research finds that conditions in the vadose zone, the unsaturated soil below the surface but above the water table, are of particular importance to seedling survival in coastal floodplain ...
