  • Test metal, concrete & other surfaces for residual oil contamination

    Surficial sampling and analysis is used to assess the existence and/or extent of oil contamination on various surfaces, rather than in soil, sediment or water. Applications include testing wipe samples for residual oils coated on aluminum, steel or other metal parts after the manufacturing process. This includes ventilation ducts, fans, AC coils and other metal working processes to see how well ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...


  • 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 ...

  • 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

    On September 11, 2008, seven years after the terrorist attacks at the Pentagon, The Pentagon Memorial was dedicated to the people who lost their lives. The Memorial is structured chronologically based on the ages of the victims, with the 184 individual Memorials placed along Age Lines parallel to the trajectory of American Airlines Flight 77. While the Memorial Units themselves are the central ...

  • IEST publishes contamination control recommended practice

    A newly revised Recommended Practice (RP) from the Institute of Environmental Sciences and Technology (IEST) describes a method for characterizing organic compounds outgassed from materials or components exposed to air or gases in cleanrooms and other controlled environments. IEST-RP-CC031.2: Method for Characterizing Outgassed Organic Compounds from Cleanroom Materials and Components is ...

  • Survey detects contamination on proposed waste disposal site

    Two small areas of radioactive contamination have been detected during a survey of grazing land adjacent to the former nuclear research site at Dounreay. They were excavated and removed to the site for analysis. One was identified as a 'minor' particle of fast reactor fuel and the other as soil contaminated with radioactivity. The finds were 5-30cm below the surface and covered by vegetation, ...

  • Analysis of produced water contaminants by ion chromatography

    Drilling for oil or gas holds many challenges. Keeping pipes free of scale deposits is one of them. This involves the monitoring of ionic components in produced water, a task that is best handled by ion chromatography (IC).Avoid clogging of your pipe systemProduced water is water trapped in underground reservoir rocks and is brought to surface along with the crude oil and gas. Besides dispersed ...

  • Scientists suggest alternative source of arsenic contamination

    New research contradicts previous findings that arsenic contamination — an environmental crisis that affects more than 60 million people in the Bengal Basin — in groundwater may result from arsenic coming from man-made ponds, suggesting instead that it originates in sediments in aquifers. Groundwater ...
