  • 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 ...

  • CH#952 - Oil Contaminated Soil

    SITE OWNER: A National Overnight Express Package Company SITE SURVEY: Site and geological surveys revealed a contaminated area north of the facility and west of a diesel tank pit. The cause of the contamination was the result of two (2) underground storage tanks (UST™). One tank contained waste oil while the other contained new oil. Both tanks had ...

  • Water repellency in oil contaminated sandy and clayey soils

    Two sites from a humid tropical environment were studied with respect to soil water repellency caused by hydrocarbon contamination. Samples were analyzed for water repellency (molarity ethanol droplet method), total petroleum hydrocarbons, acute toxicity (Microtox) and field capacity. At both sites, water absorption times were ...

  • Treatment of Oil-Contaminated Soils for Identification and Classification

    An experimental investigation was performed to evaluate the effects of oil contamination on soils and to establish a methodology to identify and classify contaminated soils. Identification and classification tests were performed before treatment, cleaning, stabilization, or disposal of contaminated soils.There are no standards for identification and classification of contaminated soils. ...

  • Surfactant–enhanced remediation of soils contaminated with petroleum hydrocarbons

    An experimental programme was undertaken to reclaim the soils contaminated with petroleum hydrocarbons. Two types of locally available soils, clay with low compressibility and poorly graded sand, were chosen for the study. Both the soils were contaminated with varying percentages of used engine oil and gasoline. Anionic surfactant Sodium Dodecyl Sulphate (SDS) was used to reclaim the contaminated ...

  • Bioremediation applied to high pH contaminated soil washing slurry

    BioFuture Ltd. in conjunction with General Smontaggi SpA have used applied environmental engineering and bioaugmentation to remediate hydrocarbon contaminated soil washing slurry. The soil washing slurry had been treated using lime to dry and stabilise it for transport to special landfill for disposal. The starting pH was 12.55 and it was successfully bioremediated so that it could be used as a ...

  • Evaluation of The Efficiency of Various Commercial Products for The Bioremediation of Hydrocarbon Contaminated Soil

    Bioremediation has become an important method for the treatment of terrestrial oil spills and is often favoured over strictly physical-chemical methods. In this study, enzymatic analyses and signature lipid biomarkers were employed to evaluate the efficacy of selected bioremediation products on control and oil contaminated soil plots. It is envisioned that these biological indicators may be used ...

  • 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 ...

  • Toxicity of fuel contaminated soil to antarctic moss and terrestrial algae

    Fuel pollution is a significant problem in Antarctica, especially in areas where human activities occur, such as at scientific research stations. Despite this, there is little information on the effects of petroleum hydrocarbons on Antarctic terrestrial biota. This paper demonstrates that the Antarctic mosses Bryum pseudotriquetrum, Schistidium antarctici, Ceratodon purpureus and the Antarctic ...

  • Assessment Of Tropical Grasses And Legumes For Phytoremediation Of Petroleum-Contaminated Soils

    Phytoremediation is a promising technology for the clean-up of petroleum-contaminated soils, especially in the tropics where climatic conditions favour plant growth and microbial activity and where financial resources can be limited. The objective of this work was to identify tropical plant species from the eastern savannahs of Venezuela suitable for this technology. Three legumes (Calopogonium ...

  • Multifunctional Well Implemented for In Situ Remediation of Hydrocarbon Contaminations in Soil and Groundwater

    Abstract A recently developed Multifunctional Well has been implemented for the remediation of subsurface contamination caused by hydrocarbon spills. Four different remediation processes can be operated within the same well. At optimal efficiency of each remediation process, successive treatment of the capillary fringes, the vadose zone, and the aquifer can be accomplished. Each 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 ...


  • 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 ...

  • Liberating contaminants for easy recovery

    The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

  • 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 ...

  • Impact–based cost–benefit analysis model for management of crude oil contaminated agricultural soil

    Evaluating the compensation payable to farmers whose farms/farmlands have been rendered unproductive due to oil spill requires adequate scientific research and improved decision–making. This work proposes a bacterial–based mathematical framework as a decision–support system for evaluating crude oil spill impact on agricultural soil. The rate of 'in situ' biodegradation of the crude oil predicts ...

  • Field-scale cleanup of atrazine and cyanazine contaminated soil with a combined chemical-biological approach

    A former agrichemical dealership in western Nebraska was suspected of having contaminated soil. Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with a mechanical high-speed mixer. ...
