  • Continuous Ground Gas Monitoring Technical Article

    It is almost inevitable in the initial phases of a construction sites development, that a Ground Gas risk assessment process is required by the local planning authority, and subsequently undertaken by a developer or their contractor. This normally encompasses spot monitoring visits that can last up to 12 months or more, if methane is found at over 5% by volume. However, it is important to realise ...

  • 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 ...

  • Los Gatos Research Now Offers Ten Ultraportable Analyzers for Soil Trace Gas Flux Measurements

    Los Gatos Research (LGR), the leader in precision trace gas analyzers, today announced that it has expanded the lower speed (up to 1 Hz) trace gas analyzer line to include as many as nine different Ultraportable trace gas analyzers with various combinations available in ten different products. This year's R&D 100 Award winning analyzer for NO2 (nitrogen dioxide) joins a series of 1 Hz ...

  • Safety measures proposed for soil fumigant pesticides

    New draft safety measures for soil fumigant pesticides proposed by the US Environmental Protection Agency last week require that users of these chemicals submit written, site-specific fumigant management plans before fumigations begin. All soil fumigant products will be classified as restricted-use pesticides, to ensure that only specially trained individuals can apply and oversee fumigant ...

  • EPA Settlement Protects Soil and Groundwater in Lawrence, Mass.

    In a recent settlement agreement with EPA’s New England office, Hilton Oil Co., Inc. will take action to come into compliance with Underground Storage Tank regulations to protect groundwater and soil at its facility in Lawrence, Mass. The company also agreed to pay a $27,000 penalty. The action stems from an EPA inspection of the facility in June 2013. A subsequent EPA complaint alleged ...

  • Cattle can help restore degraded soil

    Agriculture Research Service has tested cattle grazing on degraded soil to determine if the activity would have any effect on restoring depleted nutrients. During a 12 year period, 18 paddocks were used to monitor the soils response to different land management practices. In the end, the paddocks with medium to heavy grazing proved to be the best way to sequester nitrogen and carbon in the soil. ...

  • Soil microbes hold key to climate puzzle

     Climate scientists puzzled by the traffic of carbon between soil and air may have to think more deeply about the role played by soil microbes − the planet’s smallest inhabitants. One research team has just found that soil microbes could actually lighten the colour of arid land soils, to  ...

  • Poulsbo, Wash. Gas station agrees to pay over $11,000 for failure to monitor underground fuel tanks

    Central Valley Grocery gas station in Poulsbo, Washington, has agreed to pay $11,356 for failing to properly monitor three underground storage tanks (USTs) for leaks for over a year. Owners and operators of USTs are required to test their tanks for leaks on a monthly basis. Failure to do so puts ground water at risk and is a violation of both state and federal law. According to Edward Kowalski, ...

  • Landfill Methane Emission Monitoring

    Methane (CH4) plays a critical role in the radiation balance and chemistry of the atmosphere. The major anthropogenic sources are anaerobic production from landfills, ruminant animals and their waste, release from the mining and use of fossil fuel, burning of biomass, etc.. On average, over the global scale, landfill methane emissions contribute between 10-19% of the anthropogenic methane burden ...

  • Monitoring contamination without excessive cost

    Environmental monitoring should be undertaken with the best available technology within reasonable cost constraints (i.e. BATNEEC). However, the best technology is often the most expensive, so instrument rental is increasingly the favoured option. James Carlyle, General Manager at specialist instrument hire company Ashtead Technology Rentals, explains. The requirement for environmental ...
