  • ASTM D7758 - 11 Standard Practice for Passive Soil Gas Sampling in the Vadose Zone for Source Identification, Spatial Variability Assessment, Monitoring, and Vapor Intrusion Evaluations

    Passive soil gas samplers are a minimally invasive, easy-to-use technique in the field for identifying VOCs and SVOCs in the vadose zone. Similar to active soil gas and other field screening techniques, the simplicity and low cost of passive samplers enables them to be applied in large numbers, facilitating detailed mapping of contamination across a site, for the purpose ...

  • Environmental contamination as a potential source of MRSA transmission

    Ehsanollah Ghaznavi-Rad, MSc, of the Department of Medical Microbiology and Parasitology at the Universiti Putra Malaysia, and colleagues, report in a research brief in Infection Control & Hospital Epidemiology on a study they conducted to trace the source of nosocomial transmission of methicillin-resistant Staphylococcus aureus (MRSA) by investigating the impact of healthcare workers and the ...

  • `Chemical fingerprints` could reveal source of mercury pollution

    Scientists have described a new method for tracking down the source of mercury pollution from burning coal. By analysing the chemistry of the pollution, it is possible to identify which region the coal was originally from. Mercury pollution in the atmosphere comes mainly from coal-fired power stations and chemical plants. Mercury is naturally present in coal and is emitted when it is burned as ...

  • Journal article evaluates methane sources in groundwater in Pennsylvania

    The findings of a new study in the journal Groundwater suggest that methane concentrations in Susquehanna County water wells in Pennsylvania can be explained without the migration of Marcellus shale gas due to hydraulic fracturing. “Testing of 1,701 water wells in northeastern Pennsylvania shows that methane is ubiquitous in groundwater, with higher concentrations observed in valleys vs. ...

  • Groundwater papers link methane in groundwater to natural sources

    A pair of papers in Groundwater®, NGWA's bimonthly technical publication, finds a high level of methane in water wells from two Texas counties is most likely from shallow natural gas deposits, not natural gas leaks caused by hydraulic fracturing operations in the underlying Barnett Shale.  The research builds on previous studies on well water quality in the Barnett Shale ...

  • Source of Mystery Mercury Spill in Arizona Remains Unknown

    On March 31st, the El Mirage Fire Department released a news bulletin about a mercury spill at a bank-owned home in the town.  Fire crews from El Mirage and hazardous materials teams from the nearby towns of Peoria and Surprise responded to the scene.  It is not known how a quantity of greater than one pound of mercury was spilled at the vacant home. Anyone with information concerning ...
