  • In Situ Treatment Technologies for Contaminated Soil

    Compared to excavation and ex situ treatment, the use of these technologies offers several benefits, such as addressing deep contamination and generally costing less. The summary for each in situ technology includes a basic description of the technology, its implementation, applicability based on contaminants and site characteristics, general limitations, costs, and status of the ...

  • 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. ...

  • In-Pile thermal desorption for treatment of Dioxin-Contaminated soil in Japan

    Abstract A demonstration of thermal treatment of dioxin-contaminated soil was completed in Japan, under the sponsorship of the Japan Ministry of the Environment. TerraTherm’s proprietary In-Pile Thermal Desorption process was demonstrated to successfully treat the soil to the required standard of 1,000 picograms of 2,3,7,8-tetrachlorodibenzodioxin (TCDD) toxic equivalents (TEQ) per ...

  • Remediation of Metals-Contaminated Soils and Groundwater

    A range of technologies is available for remediation of metals-contaminated soil and groundwater at Superfund sites. General approaches to remediation of metal contamination include isolation, immobilization, toxicity reduction, physical separation and extraction. These general approaches can be used for many types of contaminants but the specific technology selected for treatment of a ...

  • 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 ...

  • Composting of petroleum contaminated soil case study

    Soils contaminated with hydrocarbons are generated during oil and gas production. Remediation by land treatment is a popular, inexpensive option however, in cold climates temperature limits the time available for treatment each year. Companies would prefer an economical, low maintenance treatment alternative which could operate throughout the year in cold climates. Environmental BioTechnologies, ...

  • 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 ...

  • Bioremediation of petroleum contaminated Soils in Brazil Using AgroRemed

    At Atuba at the corporate site of COPEL, a state owned utility company, soil was heavily contaminated with transformer oil due to a long history of contamination since 1964 probably due to unsafe practices of storage and cleanup. The level of contamination measures as TPH in soil was as high as 766,695 ppm and much of the contamination was at a depth of 1 meter. The site is located on a hill and ...

  • In Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • Influence of phosphate and citric acid on the phytoextraction of As from contaminated soils

    The influence of phytoextraction in arsenic (As) contaminated soil on the phosphate and citric acid addition were investigated using Pteris vittata L. (Chinese brake fern). The As uptake in the fronds increased 85% in As–spiked soil when phosphate was added. The addition of citric acid for 2 weeks to the phosphate added soils resulted in the highest As uptake by 75% compared to only ...

  • Evaluation of sodium lignosulphonate for the remediation of chromium–contaminated soil and water

    Commercial sodium lignosulphonate, a by–product of sulphite pulp leaching, was evaluated for the remediation of soil and water contaminated with hexavalent chromium. Two series of bench–scale tests were performed: (a) removal of chromium from water using reagent binding and membrane separation; and (b) stabilisation of chromium in the soil using chemical soil flushing. Water treatment tests were ...

  • Treatment of salt affected soil in the oil field

    Soils, drill cuttings and other solid wastes which are exposed to high levels of salt through spillage from drilling and producing operations, pipe line breaks or leaks, become saturated with sodium. Although the EPA and the industry have demonstrated that the vast majority of such wastes are non-hazardous, in actuality, they have an adverse impact on the fertility of the soil. The degree of salt ...
