  • Mapping pesticide contamination risk

    A new computerised tool helps regulators identify water sources at risk of pesticide contamination. The tool can be used to produce maps indicating water bodies at risk of contamination by taking into account: adjacent land-use, the concentration of pesticides in the environment and biological indicators of contamination. Protection of water resources is a key priority for the EU and water bodies ...

  • Identifying areas at risk for arsenic contamination

    The contamination of groundwater with arsenic poses a risk to the health of millions of people, especially in the densely populated river deltas of Southeast Asia. To date, no method has been available for identifying high-risk areas without conducting costly sampling campaigns. Now, Eawag has developed a model that allows vulnerable areas to be pinpointed using existing data on geology and soil ...

  • Predicting contamination of farmland after flooding

    Floods and the resulting damage to agricultural and urban environments are likely to increase as a result of climate change. Major floods in Europe, such as those affecting the Elbe River in Germany in August 2002, can result in contamination by heavy metals of flooded farmland. Taking zinc as an example, a new modelling approach showed that there was more than a one in three chance that ...

  • Salmonella Contamination Suspected in Bagged Salads

    Dole Fresh Vegetables recently announced a voluntary recall of bagged salads due to possible Salmonella contamination after New York authorities found that a random sample of the product tested positive for the pathogen.   756 cases of DOLE® Seven Lettuces salad with Use-by Date of April 11, 2012, UPC code 71430 01057 and Product Codes 0577N089112A and 0577N089112B are being ...

  • CoMo170 hand held contamination monitor

    Laboratory Impex Systems launches CoMo170 a light weight, hand held contamination monitor. The CoMo170 monitors a large area - 170 cm2, its innovative CoMo detector technology uses thin-layer plastic scintillation, negating the need for gas filled or gas-flushed detectors, thus minimising operating costs.Capable of simultaneous or selective alpha and beta-gamma contamination measurement, CoMo170 ...

  • Pennsylvania Groundwater Contaminated By Coal Ash

    HARRISBURG, Pennsylvania, September 18, 2007 (ENS) - Disposing of coal ash in mines is contaminating water supplies throughout Pennsylvania, according to a report released today by the advocacy group Clean Air Task Force and the nonprofit, public interest law firm Earthjustice. In 10 of 15 mines examined across the state, groundwater and streams near areas where coal ash, or coal ...

  • PFOS not widespread contaminant of drinking water

    Although limited data exists on perfluorinated chemicals in water, a recent study published in CIWEM’s Water and Environment Journal has found that perfluorooctane sulphonate (PFOS) is not a widespread contaminant of drinking water in England. PFOS has a number of industrial and commercial uses, including as a surfactant for fire-fighting foam, a mist suppressant for metal-plating baths and ...

  • Pharmaceuticals recalled due to metallic contaminants

    This month a manufacturer of an intravenous blood pressure medication announced a voluntary recall of their product because of the potential presence of foreign matter. The material, according to reports, is made up of sub visible inert stainless steel particulates of approximately 2.5 microns in diameter.Contaminated pharmaceuticals are not a new phenomenon. In the past there have been numerous ...


  • Encouraging results in evaluating groundwater contaminants

    The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation’s groundwater. The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the ...

  • Drinking water wells vulnerable to contamination

    New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells. All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States ...

  • 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.” ...

  • Unique surfacing adds sound and feel to the Pentagon Memorial
