  • EPA awards $2.5 million to Arizona to improve surface water quality

    The Environmental Protection Agency awarded $2.5 million to the State of Arizona for projects to help restore water quality in the state’s polluted water bodies. With an additional $1.6 million leveraged by the state for these activities, more than $4 million is available this year to improve surface water quality. Recent water quality data shows that a significant percentage of surface ...

  • Water Quality System

    Let me explain that our basic idea is how better to use the not many typologies (and parameters) of on-line sensors available on market to make low-cost sustainable intelligent monitoring. We all know that the total water quality is related to about fifty of quality measurement analytic parameters, but on-site and in on-line way, it is possible to detect only about ten electro-chemical or ISE ...

  • 3-D laser scanning: A new soil quality measurement

    Soil researchers pay close attention to bulk density, as it is one of the most common soil measurements and it is often used as a measure of soil quality. A soil’s bulk density can be indicative of the ease of root penetration, water movement, and soil strength. Measuring this value with traditional methods has been difficult in the past, but researchers have developed a new method using laser ...

  • Surface waters: 12 new controlled chemicals, three pharmaceuticals on watch list

    Twelve new substances will be added to the EU priority list of those known to pose a pollution risk to surface waters under rules endorsed by MEPs on Tuesday. For the first time, three pharmaceuticals will also be included in a "watch list" of emerging pollutants that could one day be placed on the priority list. “Water policy is a long-term policy. Our citizens should have access to clean ...

  • New ways of measuring our water environment

    General Quality Assessment figures from the Environment Agency released this week show that 76 per cent of all UK rivers in the UK achieved ‘good’ or better status for chemical water quality in 2007. From 2008, the new European Water Framework Directive replaces General Quality Assessment,  which means that the way of measuring the quality of our water bodies has changed. As well as rivers, ...

  • New approaches to measuring metal concentrations in water in Europe

    EU Member States are required to monitor concentrations of metals in surface water in order to comply with regulations laid out under the Water Framework Directive. Current sampling methods may produce uncertain estimates of pollutant levels. A new study provides evidence that combining different sampling techniques can produce more reliable estimates. In 2006, the European Commission issued a ...

  • 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, ...

  • NACWA affirms commitment to water quality monitoring for nutrients

    The National Association of Clean Water Agencies (NACWA) supports the collection of robust water quality data for nutrients to ensure scientifically based decision-making. The Association’s Board adopted a resolution icon-pdf on April 22 that its public agency members will, as appropriate and feasible, support the ...

  • Xylem launches new ‘FerryBox’ water quality monitor

    Xylem Analytics UK and Aanderaa Data Instruments have launched a new marine water quality monitor which has been designed to enable wider deployment of water quality sensors on ferries and other marine vessels. The ‘SOOGuard’ will be launched at Ocean Business 2013 in April and Xylem’s David Goldsmith says: “In order to encourage the operators of ferries to allow the ...

  • 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 ...

  • Effects of shale gas development on water quality: experiences from the Marcellus Shale

    The impact of shale gas development on surface water quality has been explored in a recent study. Focusing on the Pennsylvania portion of the Marcellus Shale formation (which stretches from West Virginia to the Canadian border), the researchers conclude that shale gas wells and the treatment of shale gas extraction waste have measurable impacts on downstream surface water quality. The ...

  • Sensors in Space Allow Daily Coastal Water Quality Monitoring

    ST. PETERSBURG, Florida, August 31, 2007 (ENS) - Using data from instruments aboard two NASA satellites, Florida researchers have created a way to map the fleeting changes in coastal water quality from space - something that has long evaded researchers and coastal managers relying only on ground-based measurements. This information has direct application for resource managers working on ...

  • EPA Announces Awards to College Students in National Water Quality Challenge

    Today the U.S. Environmental Protection Agency (EPA) announced seven undergraduate and graduate student winners for phase 1 of the National Aquatic Resource Surveys (NARS) Campus Challenge, recognizing exemplary research in the area of water quality and ecosystems. Announced in February, the NARS Campus Challenge encourages students to develop proposals for research projects that find innovative ...

  • UGA Student wins National Water Quality Challenge Award

    Today the U.S. Environmental Protection Agency (EPA) announced that James Wood, a Ph.D. candidate from the University of Georgia located in Athens, Ga., was one of seven undergraduate and graduate student winners for Phase 1 of the National Aquatic Resource Surveys (NARS) Campus Challenge. The award was based on Wood’s proposal to assess major trends in river plants and measure the ...

  • European Commission welcomes EP vote on water quality standards

    The European Commission welcomes the European Parliament's second reading vote approving the agreement reached with the Council on the proposed directive on environmental quality standards in the field of water.

  • Quality of harvested rainwater unsufficient for drinking

    A study published in the Journal of Water and Health has examined microbial contamination of harvested rainwater in the Netherlands. The water did not comply with Dutch drinking water legislation and factors affecting contamination were found to include storage, roof and environmental conditions. In remote and rural areas where access to tap water is limited, rainwater harvesting is common ...


  • 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.
