  • Optical water quality assessment

    Scientists at the U.S. Geological Survey (USGS) have proven that measuring fluorescence could improve source water monitoring during a study of the McKenzie River in Oregon.  The study was designed to assess the amount, type and source of dissolved organic carbon that exists in all sources of drinking water. Dissolved organic carbon can react with chlorine during water treatment and form ...

  • 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

    Water Quality Assessment Authority (WQAA) has been constituted with the mandate for protection of surface and groundwater quality under Environment Protection Act 1986. 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 ...

    Purity's founder, Aapo Sääsk has offered the services of Scarab and Purity to advise a large EU project based in London on technical solutions for the removal of disinfection by-products. EU’s FOOD QUALITY AND SAFETY Programme HiWate: HEALTH IMPACTS OF LONG-TERM EXPOSURE TO DISINFECTION BY-PRODUCTS IN DRINKING WATER The project will investigate human health risks of exposure to low ...


  • 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 ...

  • New, Improved: Water Quality Modeling Tool

    (Washington, DC ) The Environmental Protection Agency has released a new version of its acclaimed watershed management program, making it easier to use and more readily available. 'Better Assessment Science Integrating Point and Nonpoint Sources' (BASINS) is a multipurpose system that integrates environmental data, analytical tools, and modeling programs. BASINS will help regions, states, and ...

  • Scotland’s water and groundwater quality improving, says SEPA

    Water quality in Scotland is good and continues to improve. That's according to the recently published Scotland’s Water Environment Review 2000-2006 featuring water quality classification data that illustrates historical trends stretching back over the past six years.  The review, which has been published by the Scottish Environment Protection Agency (SEPA), is a valuable source of environmental ...

  • Mississippi River an `Orphan` in Terms of Water Quality

    WASHINGTON, DC, October 18, 2007 (ENS) - The U.S. Environmental Protection Agency has failed to coordinate and oversee state water quality activities along the Mississippi River, leaving the nation's largest waterway an 'orphan,' the National Research Council says in a new report. Greater effort is needed to ensure that the river is monitored and evaluated as a single system, said the ...

  • Water quality improves after fertilizer ban - study

    In an effort to keep lakes and streams clean, municipalities around the country are banning or restricting the use of phosphorus-containing lawn fertilizers, which can kill fish and cause smelly algae blooms and other problems when the phosphorus washes out of the soil and into waterways. But do the ordinances really help reduce phosphorus pollution? That’s been an open question until now, says ...

  • 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 ...

  • Real time surface water quality monitoring

    During Aquatech 2015 the Dutch company BlueLeg Monitor launched the newly developed fixed position EcoWatch for continuous real time surface water monitoring focusing upon relevant ecological water parameters.
