  • Climate change pose risks for waste water treatment

    A Simplified Climate Change Impact Assessment Tool (SCIAT) addresses the specific needs of the water industry, translating climate change projections into real-world impacts. A recent study in CIWEM’s Water and Environment Journal demonstrates its application in assessing the impacts of climate change on the reservoir water quality and water treatment plant (WTP) operations at Grafham Water ...

  • Unlocking the water held by US forests not so easy, say experts

    Can forests, which process nearly two-thirds of the nation’s water supply, be managed to help slake our growing demand for water and avert the worst consequences of climate change? A new report from the National Research Council suggests a need for caution in trying to tap greater water output from forests, and recommends more research and citizen involvement to help protect water quality and ...

  • WHAM7 metal speciation modelling software released

    The Centre for Ecology and Hydrology have recently released an updated version of the Windermere Humic Aqueous Model (WHAM). WHAM is a chemical speciation model for predicting the speciation of metals in aqueous systems containing naturally occurring organic ligands. Previous versions of WHAM have been critical in the development of Biotic Ligand Models (BLMs) for predicting the toxicity of trace ...

  • Toxicity tests improve the assessment of harbour sediment quality

    Harbour sediments should be tested for their toxic effects on living organisms in addition to being subject to the chemical, physical and biological tests usually conducted to assess water quality, according to recent research from Portugal. This would provide a better environmental assessment of dredged material to help guide port authorities’ decisions on its disposal. Under the Water ...

  • Better integration of temporary rivers into the Water Framework Directive

    Improvements to EU water policy have been proposed in a recent study, to help ensure that temporary rivers and streams in the Mediterranean are adequately protected in line with the goals of the Water Framework Directive (WFD). The researchers suggest new classifications for river types, and highlight the importance of distinguishing between natural and human-derived causes of intermittent water ...

  • The world’s first model for engineered nanoparticles in surface waters

    Researchers of Wageningen University provide the world’s first spatiotemporally explicit model that simulates the behaviour and fate of engineered nanoparticles (ENPs) in surface waters. Wageningen researcher Bart Koelmans: “This is important in order to assure safe nanotechnology. We do need to have an assessment of the risks of ENPs to man and the environment.” ...

  • Using micro-organisms to monitor river health

    Monitoring changes in microscopic organisms called diatoms can assist in evaluating the quality of water over an entire river watershed. Researchers from France have developed a new index that could help Member States fulfill the EU's Water Framework Directive 2000 (WFD). The WFD aims to achieve good ecological and chemical status in surface water bodies by the year 2015. Diatoms are a type of ...

  • Energy-efficient water purification made possible by Yale engineers

    Water and energy are two resources on which modern society depends. As demands for these increase, researchers look to alternative technologies that promise both sustainability and reduced environmental impact. Engineered osmosis holds a key to addressing both the global need for affordable clean water and inexpensive sustainable energy according to Yale researchers. Yale doctoral student Robert ...

  • Sophisticated soil analysis for improved land use

    Soil variation occurs across multiple geographic scales ranging from vast climatic regions of the Earth to a 50 acre farm field to the molecular world of soil nano-particles in a pinch of soil. For example, in a forest or an agricultural field, soil properties vary from the summit of a hill down to the base. Within a single soil aggregate that may be less than a quarter inch in diameter, there ...

  • 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 ...
