  • 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 ...

  • 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 ...

  • Pesticide impact: comparing lab, field-scale results

    Assessing the environmental risk of pesticide use is an important, complex task that requires knowledge of the equilibrium sorption parameter. This helps researchers assess the risk of pesticides leaching into groundwater. For cost-effective assessments, this is usually determined through batch experiments that find the amount of pesticide in test soils as a function of concentration at a ...

  • Wind drives oxygen transport in Arctic waste rock

    The growth of the diamond mining industry in Canada’s Northwest Territories has led to significant economic benefit to the region with three operating mines producing approximately 13% of the world’s diamonds in 2008, according to the Mining Association of Canada. However, the long-term benefit to northern communities will depend on careful environmental management of mining activities. The ...

  • MOE presents: provincial water monitoring networks

    Dave Rudolph – "Emerging Needs for Temporal and Spatial Data Precision" Dave Rudolph, with the University of Waterloo, started the symposium off with a very thought provoking presentation on the value of data. Dave used case studies to illustrate how different factors impact the quantity and quality of water resources, and how a small change can affect these conditions quickly and ...
