  • 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

  • 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.

  • 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.
