  • ASTM E1216 - 11 standard practice for sampling for particulate contamination by tape lift

    The tape lift provides a rapid and simple technique for removing particles from a surface and determining their number and size distribution. By using statistically determined sample size and locations, an estimate of the surface cleanliness level of large areas can be made. The user shall define the sampling plan. The sampling plan shall consider the importance of surface geometry ...

  • Water contamination detector

    A contamination event at a UK water pumping station was successfully detected by the Chelsea Technologies FASTtracka II system. The event was automatically detected using the FASTtracka II, Fast Repetition Rate (FRR) chlorophyll a fluorometer combined with a novel Red, Amber, Green (RAG) algorithm, which has been developed to provide continuous, real-time protection for water supplies at the ...

  • Shedding a light on contaminants

    Name a current environmental challenge. Global climate change? Loss of endangered species? What about soil contamination? Soil pollution rarely makes headlines, though it is a prevalent global issue. According to the European Environment Agency, 39 member states in Europe had over 2.5 million contaminated soil sites in 2011. Sharon O’Rourke, researcher at University ...

  • EPA Region 7 Provides $2.4M to Joplin, Mo., to Sample and Remediate Contaminated Soils Disturbed by May 2011 Tornado

    EPA Region 7 will provide an additional $2.4 million to the City of Joplin, Mo., to help sample and remediate lead and cadmium-contaminated soils that were disturbed during the May 2011 tornado and subsequent recovery efforts. The new federal funding, announced today by EPA and city officials, should allow Joplin to replace soils and restore yards at an estimated 240 homes, parks, playgrounds and ...

  • U.S. EPA begins perchlorate contamination sampling at residence associated with former mojave pyrotechnics, inc., site in Barstow

    This week, the U.S. Environmental Protection Agency began collecting surface and subsurface soil samples to test for perchlorate contamination at the Poplar Street home of the former owner/operator of Mojave Pyrotechnics, Inc., a defunct fireworks manufacturing company that operated on North Yucca Street in the 1980s, in Barstow, California. “EPA will work with the City of Barstow and the ...

  • EPA signs action memorandum, announces plans for off-site sampling for contaminants at carter carburetor site

    EPA Regional Administrator Karl Brooks today signed the Agency’s official Action Memorandum for the Carter Carburetor Site in St. Louis, Mo., placing the polluted industrial property one step closer to a comprehensive cleanup that is estimated to cost at least $27 million. In a separate but related action, Brooks announced today that in response to the concerns of community members and ...

  • US Labor Department`s OSHA posts results of sampling for contaminants at Sandy cleanup areas in New York and New Jersey

    The U.S. Department of Labor's Occupational Safety and Health Administration has posted results of its initial industrial hygiene sampling of locations in New York and New Jersey where recovery work in connection with Hurricane Sandy is being performed. The results are posted on OSHA's website at: http://www.osha.gov/sandy/sample_results.html. ...

  • Lead-contaminated soils removed from three schools in St. Francois county, MO.; sampling results for parks studied

    Efforts by EPA Region 7 to remove lead-contaminated soils and replace them with clean soils are nearing completion at three schools in St. Francois County, Mo., while risk assessors for the Agency are studying results of soil sampling from 11 public parks in the county to determine next steps for addressing lead contamination at those locations. Action to remove and replace soils began last week ...

  • Cutting-Edge Developments in the Evaluation of Contaminants

    Learn how to optimize your sample extraction and analysis tasks, and then apply these techniques to your application.

  • 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 amount of oil in contaminated soils

    Scientists are reporting a new technique for mapping and testing oil-contaminated soils. Traditionally, samples need to be collected from the field and returned to a lab for extensive chemical analysis, costing time and money when neither is readily available during a clean-up operation. The new method can take measurements in the field and accurately predict the total amount of petroleum ...

  • 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 ...

  • 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 ...

  • Cholera outbreaks blamed on contaminated water

    Recurrent outbreaks of cholera in the western province of Nyanza are caused by widespread water contamination, including seepage from latrines, health officials said. 'The major contributor to the recent outbreaks in the area was unsafe water,' Shahnaaz Sharif, the senior deputy director of medical services in Kenya's health ministry, said. 'In Kisumu, many wells are built near the latrine; ...

  • Specac Limited: Testing chocolate for contaminants

    If you haven't bitten into a chunk of plastic when you last ate a Mars Bar or Snickers, you may think there's no chance of eating any contaminants with your elevensee's. But not all foreign objects in food can be seen with human eyes. Straight-forward chocolate generally consists of coca butter, egg white, organic acids, cellulose, polyphenols, water, minerals, salts, theobromine, ...
