  • Industrial experience feedback of a geostatistical estimation of contaminated soil volumes

    Abstract: Geostatistics meets a growing interest for the remediation forecast of potentially contaminated sites (both chemical/radiological): pollution mapping, contaminated volumes estimation, integration of auxiliary information, setup of adaptive sampling strategies. This interest has been supported in France by the GeoSiPol association (Geostatistics for Polluted Sites) created in ...

  • 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, ...

  • Remediation Of MTBE Contaminated Soil And Groundwater

    Methyl tertiary-butyl ether (MTBE) is a fuel additive made, in part, from natural gas. Since 1979, it has been used in the United States as an octane enhancing replacement for lead, primarily in midand high-grade gasoline at concentrations as high as 8 percent (by volume). Since the mid-1980s, it has been widely used throughout the country for this purpose. It is also used as a fuel oxygenate at ...

  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • Phytoremediation of Alkylated Polycyclic Aromatic Hydrocarbons in a Crude Oil-Contaminated Soil

    Abstract  Phytoremediation uses plants and their associated microorganisms in conjunction with agronomic techniques to remove or degrade environmental contaminants. The objective of the field study was to evaluate the effect of vegetation establishment plus fertilizer addition on the biodegradation of alkylated polycyclic aromatic hydrocarbons in a crude oil-contaminated soil. Four ...


  • Radiological Evaluation of contaminated sites and soils VEgAS: an expertise and investigating vehicle

    Summary 1- Fontenay-Aux-Roses CEA Clean-up methodology For the denuclearisation of the first French nuclear research centre (CEA), the centre of Fontenay-aux-Roses started developing in 1999 a clean-up methodology to rehabilitate places that have been contaminated by radioactive materials. The structure of this methodology is comparable to the one that the ...

  • 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 ...

  • Innovative Project for Hydrocarbons Contamination

    Baioni Crushing Plants, leader in the aggregate crushing sector has been operating for 40 years, have recently developed equipment and methods for environmental control. Several plants have already been supplied to third parties, now Baioni have full know-how of the technology and can ensure correct conception of the line based on the specifications of the soil to reclaim and can provide ...

  • Contamination at ANA Shipyard

    ANA Shipyard is located on Elizabeth river and during additional construction work, it was discovered that the ground water was contaminated with free product due to soil contaminated with a mixture of oils and greases. Excavation of soil and replacement with clean dirt was not an option since it would contaminate the river. It was recommended by the Virginia DEQ that the cleanup should be done ...

  • One of Europe’s most contaminated sites

    VSD Avenue, a joint venture partnership between VolkerStevin, DEC and Sita Remediation, started work at the beginning of September on the remediation of the former Avenue Coking Works in Chesterfield; one of the most heavily contaminated sites in Europe. Guy Pomphrey, chairman of VSD Avenue, explains The £82m contract, signed in July, was commissioned by the client and site owner the East ...

  • Tyco earth tech - soil bioremediation

    Summary: In June 2006 EarthTech (a member of the Tyco group of companies) undertook the bioremedial clean-up treatment of hydrocarbon contaminated muddy gravel at one of their sites in Hungary. The muddy gravel was contaminated with TPH levels in excess of 300,000 mg/kg in parts and was a stern test for the feasibility of bioremediation within the region. The project was ...

  • Thermally Enhanced Soil Vapor Extraction

    Introduction Thermally enhanced SVE is a full-scale technology that uses electrical resistance/electromagnetic/fiber optic/radio frequency heating or hot-air/steam injection to increase the volatilization rate of semi-volatiles and facilitate extraction. Thermally enhanced SVE is normally a short- to medium-term technology. Electrical Resistance Heating Electrical resistance heating uses ...

  • Isatis and Kartotrak, an efficient combination for the characterization of radiological contaminations

    Kartotrak is a GIS platform developed by the CEA (the French Atomic Energy Authority) and Geovariances for real-time characterization of radiological contaminations. Dismantling former nuclear sites requires a preliminary characterization of radiological contamination, for both external areas and nuclear facilities. Such characterization usually relies on several steps: ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Spoil, rubble and a soil-tar mix

    National Grid and Wales and West Utilities recently completed their first joint remediation project at the Aberaman Gasworks following the sale of the Wales and south west of England gas network in 2005. Here Scott Lewis from National Grid and Ashley Griffiths from Wales and West Utilities explain the challenges and processes. The project was undertaken using a stabilisation and solidification ...

  • Soil treatment by solvent extraction and catalytic hydrodehalogenation

    We investigated the extraction of halogenated hydrophobic organic contaminants (HHOCS) from soil, and the subsequent catalytic hydrodehalogenation of extracted HHOCs. We used water/ethanol mixtures as the solvent and pentachlorophenol and 1,2,4,5–tetrachlorobenzene as target contaminants. The efficiency of extraction improved with increasing contact time and/or increasing ethanol fraction ...

  • Common Treatment Technologies for Inorganics in Soil, Sediment, and Sludge

    The most commonly used treatment technologies for inorganics in soil, sediment, and sludge include solidification/stabilization (S/S), excavation and off-site disposal, and acid extraction. These treatment technologies are described briefly below. Solidification processes produce monolithic blocks of waste with high structural integrity. The contaminants do not necessarily interact chemically ...
