  • 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 ...

  • 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 ...

  • 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.” ...

  • 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 ...

  • Nanostructures to facilitate the process to eliminate organic contaminants in water

    In her PhD thesis, Silvia Larumbe-Abuin has developed nanostructures that assist in the process to decontaminate water. The nanostructures (particles of a microscopic size of between 1 and 100 nanometres) are coated in titanium oxide to which nitrogen has been added. This allows sunlight, rather than ultraviolet radiation, to trigger the process involving the chemical reaction and destruction of ...

  • Emerging Contaminants: New Challenges for the Water Industry

    Over the past decade there has been growing concern regarding the presence of biologically active contaminants including endocrine disrupters, pharmaceuticals, personal care products and other substances in the aquatic environment. Emerging contaminants not only include those substances in active or past production, but also include their metabolites and other transformation products and chemical ...


  • 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 ...

  • Michigan`s New Surface Water Information Management System

    LANSING, Michigan, July 6, 2007 (ENS) - The state of Michigan has developed a new online tool for water managers and the general public to track the water quality of the state's rivers, lakes, and streams. The Michigan Surface Water Information Management, MiSWIM, system was introduced in late June by the Department of Environmental Quality, in cooperation with the Department of Natural Resources ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Drinking water in Gaza Strip contaminated with high levels of nitrate

    Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water. 90 per cent of their water samples were found to contain nitrate concentrations that were between two and eight times higher than the limit recommended by the World Health Organization (WHO), say the researchers from ...

  • US drinking water and watersheds widely contaminated by hormone disrupting pesticide, Atrazine

    A widely used pesticide known to impact wildlife development and, potentially, human health has contaminated watersheds and drinking water throughout much of the United States, according to a new report released by the Natural Resources Defense Council (NRDC). Banned by the European Union, atrazine is the most commonly detected pesticide in U.S. waters and is a known endocrine disruptor, which ...

  • 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 ...
