  • Impacts of groundwater on local rainfall under a changing climate

    Climate change is expected to bring hotter conditions to many important agricultural regions. This will affect rates of evaporation from the ground and may also have an impact on local rainfall patterns. A recent study suggests that the depth of groundwater may determine the susceptibility of a region to drought following changes in temperature and rainfall. Understanding the transfer of water ...

  • Predicting drainage impacts

    Predicting the drainage impacts on downstream peak events is complex because it involves studying many physical processes at different interdependent scales: the individual field, the drainage network, and the catchment. This group of researchers from France and North Carolina performed an experiment performed in a small subsurface-drained catchment (130 ha), east of Paris, France. The main ...

  • NGWA and GWPC to hold April meeting to explore “Groundwater for a Thirsty World”

    The National Ground Water Association (NGWA) and the Ground Water Protection Council (GWPC) will hold a joint meeting April 11-15 in Denver to explore the application of science and practice to the theme, “Groundwater for a Thirsty World.” The meeting is designed to bring together regulators, practitioners, natural resource managers, policymakers, municipal planners, banking industry ...

  • 2008 Groundwater Summit brings top scientists and industry leaders to Memphis

    The National Ground Water Association's 2008 Ground Water Summit taking place March 30-April 3 in Memphis, Tennessee, features 20 sessions covering the latest in ground water science, technology, and ground water policy. This fourth annual Ground Water Summit brings together local, national, and international science partners to exchange information on scientific, policy, and regulatory issues ...

  • The importance of groundwater monitoring

    Groundwater monitoring is an essential element in any environmental information system. Based upon validated groundwater monitoring data, information is derived on which decisions can be made. Constant monitoring provides the necessary data input for your smart environment and is basically the basis of the decision making process concerning spatial planning and climate change adaptation. As in ...

  • How vulnerable is our groundwater?

    When water travels through soil and bedrock to the water table, it carries minerals, nutrients or chemicals from the surface with it. Environmental research is increasingly concerned with preferential flow, or the movement of water through pores and cracks at a faster rate and bypassing most of the surrounding material, either soil or fractured rock. A special section on preferential flow ...

  • DEP Awards More than $2.25 Million in Mine Reclamation Contracts

    The Department of Environmental Protection announced today it has awarded $2,252,855 for remediation projects at abandoned mine sites in Butler, Cambria, Clarion, Jefferson and Luzerne counties. The remediation will reclaim 181 acres to pre-mining conditions by planting tens of thousands of trees, re-grading thousands of cubic yards of steep slopes left by mining, stabilizing old mine pits and ...

  • Cedarburg, Wisconsin to Be Cleansed of PCBs

    CHICAGO, Illinois, October 5, 2007 (ENS) - The Cedar Creek Superfund site is in a suburban residential area in southeastern Wisconsin north of Milwaukee in the historic city and township of Cedarburg. It would be a pleasant place to live except that PCBs from two local companies have contaminated Cedar Creek so severely that the area has been placed on the U.S. Environmental ...

  • ASTM E2856 - 11 Standard Guide for Estimation of LNAPL Transmissivity

    LNAPL transmissivity is an accurate metric for understanding LNAPL recovery, is directly proportional to LNAPL recoverability and tracking remediation progress towards residual LNAPL saturation. LNAPL transmissivity can be used to estimate the rate of recovery for a given drawdown from various technologies. LNAPL transmissivity is not an ...

  • Solving history’s ‘largest mass poisoning’

    Researchers in MIT’s Department of Civil and Environmental Engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years. The research suggests that human alteration to the landscape, the construction of villages with ...

  • Screening soil moisture conditions reveals an increased risk of drought in a Swedish drainage basin

    The risk of drought in the Norrström drainage basin, Sweden, increased during the 20th century, a new study has found. As the frequency of the dry periods increased, less water was available in the landscape for agriculture and for the resupply of groundwater — despite an increase in precipitation in the area over the same period. The researchers reached this conclusion after screening ...

  • Locus Technologies Expands EIM Software to Manage Hydro Fracturing Data

     - Locus Technologies (Locus), the industry leader in Web-based environmental software, announced today that it has expanded its flagship product to manage data and information for natural gas exploration and production sites that use hydro fracturing to extract gas from shale. Locus designed this expanded module in its Environmental Information Management (EIM) software specifically ...

  • Sequestration on shaky ground

    Original story at MIT News Carbon sequestration promises to address greenhouse-gas emissions by capturing carbon dioxide from the atmosphere and injecting it deep below the Earth’s surface, where it would permanently solidify into rock. The U.S. Environmental Protection Agency estimates that current ...

  • New tool could aid safe underground storage of CO2, says MIT

    To prevent global warming, researchers and policymakers are exploring a variety of options to significantly cut the amount of carbon dioxide that reaches the atmosphere. One possible approach involves capturing greenhouse gases such as carbon dioxide at the source -- an electric power plant, for example -- and then injecting them underground. While theoretically promising, the technique has never ...

  • Aided by the Sea, Israel Overcomes an Old Foe: Drought

    A hefty tax was placed on excessive household water consumption, penalizing families with lawns, swimming pools or leaky pipes. So many of Mr. Zvieli’s clients went over to synthetic grass and swapped their seasonal blooms for hardy, indigenous plants more suited to a semiarid climate. “I worried about where gardening was going,” said Mr. Zvieli, 56, who has tended ...
