  • Soil protection

    On 13 September, MEP Cristina Gutiérrez-Cortines presented the draft directive on soil protection to members of the European Parliament's ITRE committee (Industry, technology, research and energy). Ecological NGOs present at the meeting were not reassured. 'We are disappointed with it. This directive is in danger, when it could be an essential lever for a genuine policy on soil protection on a ...


  • Gas sensors `see` through soil to analyze microbial interactions

    Rice University researchers have developed gas biosensors to “see” into soil and allow them to follow the behavior of the microbial communities within. In a study in the American Chemical Society’s journal Environmental Science and Technology, the Rice team described using genetically engineered bacteria that release ...

  • Gas stations fined over US$3m for soil and groundwater contamination

    The US Environmental Appeals Board (EAB) has upheld the agency’s enforcement action against the owner of Lowest Price gas stations in Maryland, Virginia and the District of Columbia. In cooperation with state and D.C. officials, EPA filed a complaint in September 2002 against gas station owner, Euclid of Virginia, Inc. for violating regulations designed to detect and prevent fuel leaks from ...

  • BTEX contamination of soil and water

    BTEX is an acronym for benzene, toluene, ethylbenzene and xylene. They are all volatile organic compounds (VOCs) found in petroleum hydrocarbons. Contamination of soil and groundwater from BTEX has occurred at petroleum and natural gas production areas, gas stations and areas with underground and above-ground storage tanks of petroleum products. The compounds are also produced in large scale by ...


  • Rediscovering sound soil management

    At the same time that demand for food is soaring along with the world’s population, the soil’s ability to sustain and enhance agricultural productivity is becoming increasingly diminished and unreliable. Fortunately, it’s not too late to restore our soil resources. What it will take, say the editors and contributors to a new book, Soil Management: Building a Stable Base for ...

  • Even soil feels the heat

    Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year since 1989, according to an analysis of past studies in this week's issue of Nature. The scientists also calculated the total amount of carbon dioxide flowing from soils, which ...

  • Soil exhibition inspires

    With an estimated 2 million visitors and 4.3 million hits on the interactive website, “Dig It! The Secrets of Soil” demonstrates the ability of inspiration to channel interest into an exciting, but sometimes confusing science. The lessons of “Dig It!” are now available to inspire the next steps in soil education. Inspiration, rather than teaching, guided the design of “Dig It! The Secrets of ...

  • Utah microbubbles clean dirty soil

    Microbubble technology developed at the University of Utah has the potential to boost a wide range of environmental clean-up efforts around the world. Uses include removing oil and gas byproducts from water, removing organics and heavy metals from industrial sites and removing harmful algae from lakes. "It's very gratifying to see our technology at work in the field", says Andy Hong, who ...

  • Smithsonian exhibition reveals impact of soil

    Starting on Saturday, October 2, visitors to The Durham Museum will enjoy a journey into the skin of the earth and explore the amazing world of soils in the new exhibition, Dig It! The Secrets of Soil. Completely familiar yet largely unknown, soils help sustain virtually every form of life on Earth. Still, it is said that we know more about the dark side of the moon than we do about the Earth ...

  • Characterising the biodiversity and functioning of European soils

    World Soil Day (Dec 5, 2014) concludes a week-long series of events in Dijon bringing together international scientists. The results of the European EcoFINDERS project, coordinated by INRA, were revealed for the occasion. This project helped create standardised methods of measuring soil biodiversity, and as a result, vital data on the health of Europe’s soils were gathered. The analyses ...

  • Gas Spill? Chill - Soil Vapor Extraction (SVE) system to alleviate high levels of gasoline vapors

    It's not often you get instant gratification. Unless you're in this bind: a 600-gallon gasoline spill due to vandalism that threatened a local municipal pump station in Oregon. As gas made its way along a sewer line trench, it infiltrated soil and below-ground infrastructure. A lost cause, right? Wrong. Enter BB&A Environmental, an RPI Group member. After ...

  • 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 ...

  • Landfill cover soil methane oxidation underestimated

    Landfilled waste decomposes in the absence of oxygen and results in the production of methane. Landfills are classified as the second-largest human-made source of CH4 in the U.S. Additionally, landfill gas contains numerous non-methane hydrocarbons that are either volatilized directly from waste materials or produced through biochemical reactions during waste degradation. Microbial methane ...
