  • Train derailment prompts contaminated land investigation

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • Fast bioremediation of a hydrocarbon contaminated site

    The use of bioremediation has been demonstrated to be a very effective treatment technology for a hydrocarbon contaminated site within a month of starting. In addition to selection and preparation of an appropriate microbial inoculum the other key considerations were effective mixing, addition of suitable nutrients and maintenance of soil moisture levels. Careful management of all these ...

  • Accelerating progress at contaminated sediment sites

    The “top five actions” presented by Bridges et al. in “Accelerating Progress at Contaminated Sediment Sites: Moving from Guidance to Practice” (IEAM 8(2):331‐338) represent an important set of normative guidelines that could accelerate progress at contaminated sediment sites. An important next step is to use those guidelines to develop recommendations about good practices. This letter presents ...

  • 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 ...


  • Quantitative risk assessment for contaminated sites in Spain

    Environmental Quantitative Risk Assessment is one of the key factors in the Decision Making Process for contaminated sites. Numerous decisions have to be made before, during and after conducting a quantitative risk assessment.Risk assessment is based on the information gathered previously: Historical information (Phase I) Site characterization (Phase II) Toxicological ...

  • Modeling Leachate Contamination and Remediation of Groundwater at a Landfill Site

    Leachate contamination of an aquifer from a landfill sitewas simulated using the groundwater flow and transport model SUTRA developed by the U.S. Geological Survey. The model calibration was performed by spatially adjusting the hydraulic conductivity in order to capture the measured hydraulic head spatial variation and then by adjusting the dispersivity and porosity match the measured chloride ...

  • In-Situ Bioremediation Treats Contaminants at a Disposal Site

    Site Summary A TCE-contaminated plume developed from buried drums containing organic solvents on the former Duluth Airbase. Soil excavation took place in the early 1990s and a total of 1,925 yds3 of soil were treated through land farming. A few years later, site assessment activities uncovered a VOC plume in groundwater and further monitoring revealed the breakdown of TCE to daughter products ...

  • Who will do the Cleanup? (Contaminated Sites Report 2007)

    To better understand Canada’s current capacity to meet this unique labour demand, ECO Canada undertook this study in early 2006. Our work was guided by a 29-member National Steering Committee from government, industry, and academia. In addition, a full-day National Forum on Contaminated Sites was held in Vancouver on March 28, 2006 to gain support and gather comments on the project from ...

  • Risk assessment and brownfields-determining exposure to site contaminants

    The USEPA’s Brownfields Program was developed to facilitate the rehabilitation of contaminated property for re-development. EPA has set forth criteria that must be met for a revitalized property to be used for residential, commercial or industrial purposes. The main thrust of these criteria is the long-term protection of residents or visitors (including shoppers and business employees). As ...

  • NJDEP issuing remedial priority scores for contaminated sites

    Very shortly, the New Jersey Department of Environmental Protection (NJDEP) will be issuing letters to responsible parties containing a draft Remedial Priority Score (RPS) for their particular site. It is unclear how the rankings will be used, but the RPS system has been described as a tool to sort sites out for further discussion. The ...

  • Contaminated Water

    Treatment of Contaminated Mine Water Discharge Recent estimates have suggested that in the UK 2,500 km of streams and an area of 9,000 km2 of groundwater bodies are at risk of failure of Water Framework Directive Objectives due to mine water pollution (Jarvis & Rees 2004). For over two decades the Loughor Estuary in South Wales, which carries SSSI status, had been ...

  • Geostatistics for radio-contaminated site characterization - Methods and case studies

    Radiological characterization for decommissioning of nuclear sites and facilities is a key issue for the global success of such industrial projects, which imposes an efficient control of radiological hazards, cost estimation, planning and waste management. A large range of evaluation objectives co-exist during a decommissioning and dismantling (D&D) project: doubt removal, identification of ...

  • Failure of Magnesium Peroxide to Remediate Petroleum Hydrocarbon-Contaminated Sites (PDF)

    Researchers promote magnesium peroxide as a viable method to aerobically bioremediate petroleum hydrocarbons and restore groundwater quality. Suppliers claim that dissolved oxygen released in the saturated zone promotes biological growth for degrading a wide range of hydrocarbons dissolved in water and sorbed onto soil particles. Yet, staff with the CaliforniaRegional Water Quality Control Board, ...

  • The Discrete Fracture Network (DFN) approach for contaminated bedrock site characterization

    A comprehensive methodology known as the Discrete Fracture Network (DFN) Approach has been developed since the mid-1990’s as a framework for characterization of contaminated sites on fractured rock. This article provides an overview of the Approach and is followed by eight additional articles that describe the various methods that constitute this Approach. The ninth article also describes ...
