  • `Standards are desperately needed for plastic and pesticide contamination in soil´

    In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

  • How Tire Shredding Protects Wildlife

    One of the most revolutionary inventions in the history of mankind was the wheel, and the best upgrade to that invention was the rubber tire, which overcame the limitations of wooden or metal wheels and made it possible to have smooth rides at fast speeds. However, there is a significant drawback to using rubber tires: eventually, they get too worn out to be useful as tires anymore and have to ...

  • Soil baked to clean up contamination...

    Can an old drill site be cleaned up without adding truckloads of contaminated soil to the landfill? Chevron Canada will be using a technology called thermal desorption to clean up a site located 13 kilometres southwest of Pincher Creek. Leif Sollid, spokesman for Chevron, who is the operator of the site, said they considered two options for the clean up. The soil is classified as a non-dangerous ...

  • Brownfield development - Biotechnology cleans contaminated soil

    The Tooele Army Depot (TEAD) is in Tooele, Tooele County, Utah, 35 miles southwest of Salt Lake City. It consists of two separate areas, the North Area and the South Area. The North Area covers about 25,000 acres in Tooele Valley south and west of Tooele. Since 1943, TEAD has had a fourfold mission: store ammunition, demilitarize ammunition, rebuild military equipment and store military ...


  • Effects of Oversize Particles on the Density of Clean Granular Soils

    Fill material often contains particles too large to be tested in conventional testing equipment. In order to evaluate the compaction, strength, and deformation characteristics of soil containing such oversize particles, a modeling criterion is required which specifies how the soil minus the oversize particles (the soil matrix) should be tested. Questions such as whether or not to replace oversize ...

  • Using On-Site Biological Methods to Clean Up Soil

    Decontamination companies and researchers in France are working to restore polluted soil using treatments that range from biological methods to soil washing and incineration. The problem of polluted soil was dramatically illustrated prior to construction of the Stade de France soccer stadium built for the 1998 World Cup. The location of the site, on industrial wasteland just north of Paris, ...

  • Soil Washing

    Introduction: Soil washing is a water-based process for scrubbing soils ex situ to remove contaminants. The process removes contaminants from soils in one of two ways: By dissolving or suspending them in the wash solution (which can be sustained by chemical manipulation of pH for a period of time). By concentrating them into a smaller volume of soil through particle size ...

  • Soil Filters

    Soil filters (in german: Retentionsbodenfilter) are facilities for the removal of nutrients and/or pollutants; typically on the level of an industrial site, a quarter or a drainage system (sub-)catchment. Usually they are located at the discharge points to surface waterbodies to ensure water quality standards. Soil filters consist of two parts: The first part is a retention pond or basin for ...

  • Next steps in the development of ecological soil clean‐up values for metals

    This special series in IEAM presents the results from six workgroups that were formed at the workshop on Ecological Soil Levels—Next Steps in the Development of Metal Clean‐up Values. This introductory paper presents an overview of the issues assessors face when conducting risk assessments for metals in soils, key US EPA documents on metals risk assessment, and discusses the importance of ...

  • Deriving site‐specific soil clean‐up values for metals and metalloids: Rationale for including protection of soil microbial processes

    Although it is widely recognized that microorganisms are essential for sustaining soil fertility, structure, nutrient cycling, groundwater purification and other soil functions, soil microbial toxicity data were excluded from the derivation of Ecological Soil Screening Levels (Eco‐SSL) in the United States. Among the reasons for such exclusion were claims that microbial toxicity tests were too ...

  • Asbestos in soil methods

    I wanted to start off this brief technical summary with an item that appeared in the January 2009 Indoor Environment Connections publication… “Asbestos in Soil; The State of the Issue, Tom Laubenthal, Sean Fitzgerald, Alan Seagrave, P.G. In this session, Laubenthal and Seagrave will describe the nature of asbestos contamination in soil. This issue has perplexed the industry for years. What ...

  • Chemical Impregnation of Cohesionless Soils

    Existing methods to obtain and test high-quality undisturbed samples of cohesionless soil below the water table depend at some stage on freezing. This limits the range of application to relatively clean sands, and even for those soils the freezing operation is delicate, time-consuming, and costly. Moreover, there is no direct way to check, independently, the effects of the freezing process on the ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

  • Is it clean or contaminated soil? Using petrogenic versus biogenic GC‐FID chromatogram patterns to mathematically resolve false petroleum hydrocarbon detections in clean organic soils: A crude oil spiked peat microcosm experiment

    The Canadian Council of Ministers of the Environment (CCME) Reference Method for the Canada‐Wide Standard (CWS) for Petroleum Hydrocarbons (PHC) in Soil provides chemistry analysis standards and toxicity guidelines for the remediation of contaminated sites. However, these methods can co‐extract natural biogenic organic compounds (BOCs) from organic soils, causing false exceedences of toxicity ...

  • Field survey of Canadian background soils: Implications for a new mathematical GC‐FID approach for resolving false detections of petroleum hydrocarbons (PHCs) in clean soils

    The Reference Method for the Canada‐Wide Standard (CWS) for Petroleum Hydrocarbons (PHC) in Soil provides laboratories with methods for generating accurate and reproducible soil analysis results. The CWS PHC Tier 1 generic soil quality guidelines apply to four carbon ranges/fractions: F1 (C6‐C10), F2 (C10‐C16), F3 (C16‐C34) and F4 (>C34). The methods and guidelines were developed and validated ...

  • Natural Attenuation in Soils

    Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...

  • Low Flow Upholstery Cleaning Technology for Faster Cleaning

    Upholstery cleaners make the complicated task of cleaning upholstery easy, simple and quick. Chairs, sofas, draperies, fabrics in automobiles, and other such items attract dust and dirt very fast. Cleaning them manually can be extremely stressful and time consuming. Soiled upholstery can be quite an unappealing sight for people visiting your establishment or your home. Advanced upholstery ...
