  • Sediment pollution should be included in water quality assessments

    The quality of surface water is best assessed using the status of both the water and underlying sediment. A recent study concluded that water bodies risk being misclassified if sediment assessment is not included, which can lead to unnecessary recovery costs. Under the Water Framework Directive1 (WFD), Member States are required to achieve at least 'good water status' for surface water (inland, ...

  • India water quality assessment authority now constituted by law

It is conferred with the powers for issuing directions and taking measures. Its main functions are: to standardise methods for water quality monitoring and to ensure quality and data generation; to take measures to ensure proper ...

  • 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 ...

  • New indicator proposed for assessing treated wastewater quality

    The chemical, physical and microbiological characteristics of effluents from wastewater treatment plants are regulated by national and EU law for discharge into surface waters or reuse, but a wide variety of treatment options exist and monitoring all pollutants may be expensive. A new study from Italy proposes a new Wastewater Polishing Index (WWPI) to help decision makers and environmental ...

  • Water quality still deficient

    A new report by the World Health Organization and UNICEF states that the world is on track to surpass the Millennium Development Goal for drinking water access, but will fall short by one billion people for sanitation if current trends continue; access to a water source does not imply a quality water source. The Progress on ...


  • Everglades show improvement in water quality

    Researchers at the University of Florida Research and Education Centers and scientists at the South Florida Water Management District have published a report regarding the trends in water quality feeding into Everglades National Park. The report can be found in the September-October 2010 Journal of Environmental Quality, published by the American Society of Agronomy, the Crop Science Society of ...

  • ISO standards to improve quality of water services to consumers

    A suite of new ISO standards offers the international community practical tools to address the global challenge of effectively managing limited water resources in order to provide access to safe drinking water and sanitation for the world’s population. ISO has just published three standards providing guidelines for service activities relating to drinking water supply systems and wastewater ...

  • Clam invasion threatens ecosystem balance and water quality

    Invasive alien species can have destructive effects on ecosystems. A recent study has shown that the invasive Asian clam (Corbicula fluminea) is reproducing at such a high rate in the River Minho Estuary, on the Portuguese/Spanish border, that it is not only threatening native species but also the quality of the river water. The functioning of freshwater ecosystems is easily unbalanced by human ...
