  • 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 ...

  • 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 ...

  • Isolation, development and identification of salt-tolerant bacterial consortium from crude-oil-contaminated soil for degradation of di-azo dye Reactive Blue 220

    The objective of this study was development and characterization of a halophilic bacterial consortium for rapid decolorization and degradation of a wide range of dyes and their mixtures. The 16S rRNA gene analysis of developed halophilic consortium VN.1 showed that the bacterial consortium contained six bacterial strains, which were identified as Pseudomonas fluorescens HM480360, ...

  • Lysimetric studies for modelling radioactive contaminant transport in soils

    To assess the movement of contaminants in the soil mass surrounded by near/subsurface waste repository, researchers have developed several mathematical and numerical modelling techniques. However, most of these techniques consider remolded state of soil mass, which fail to reproduce exact in situ conditions and also have used inactive salts as model contaminants. Hence, in order to model ...

  • 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 ...


  • Characterization and treatability of a contaminated soil from an oil exploration zone

    Abstract: A crude contaminated soil, arising from an oil production zone in Tabasco, Mexico was studied. A sample of about 40 kg was dried and screened through meshes 10-100. Total petroleum hydrocarbons and 6 metals (Cd, Cu, Cr, Ni, V and Zn) were determined to the different portions. For soil which passed mesh 10, six non-ionic, three anionic and one zwitterionic surfactant solutions ...

  • Phytotoxicity of trace metals in spiked and field‐contaminated soils: Linking soil extractable metals with toxicity

    Soil tests have been widely developed to predict trace metal uptake by plants. The prediction of metal toxicity however has rarely been tested. The study was set up to compare eight established soil tests for diagnosing phytotoxicity in contaminated soils. Nine soils contaminated with Zn or Cu by metal mining, smelting or processing were collected. Uncontaminated reference soils with similar ...

  • Hydrocarbon contamination of a typical mangrove floor in Niger Delta, Nigeria

    The impact of petroleum hydrocarbons on the floor of a mangrove system located on one of the intertidal lands behind the barrier islands of Niger Delta basin of southern Nigeria was evaluated following the Obiafu-14 oil spillage. The area covered by the oil spill was delimited by reconnaissance and soils were sampled by grid method from the bottom and middle slopes of oil-affected and unaffected ...

  • Contaminant removal from dry and wet sands by thermal desorption

    Infrared heating was used to determine the effects of temperature and moisture on the removal of selected organic compounds from contaminated sand matrices. Quartz sand was used as a chemically inert surrogate for soil to isolate the heat transfer and mass transfer effects without any chemical contribution from soil. The selected organic contaminants were 3-nitrobenzene sulphonic acid, sodium ...

  • Compost integral in new website in building soil

    A website called “BuildingSoil” has been launched by the Washington Organic Recycling Council to help builders preserve healthy soil on building sites. It's the latest Soils for Salmon project which aims to change standard site development practices. These new “soil best management practices” will soon be required by local governments around western Washington, as they update local codes to ...

  • In-situ Technology for Clean up of Halogen Contaminated Sites - Process West case study

    Halogenated volatile organic solvents are found in the soil or ground-water at many former and active industrial sites. Fortunately highly effective remediation technologies are available to restore these former brownfields to a healthy state. The range of technologies includes the traditional approach where the contaminated soil is excavated and the volatile halogenated contaminants are ...

  • Soil physico-chemical changes following application of municipal solid waste leachates to grasslands

    AbstractConcerns about the use of residues from municipal solid waste incinerators (MSWI) in construction materials usually focus on the potential for heavy metals and organic chemicals to leach into drainage waters under the influence of rain. We hypothesised that high level of salts in the MSWI leachates may cause more of a problem, particularly on soil physico-chemical properties. Both bottom ...

  • Solution blooming for fracking spills?

    Blooming salts may clean up after brine spills North Dakota's oil boom can have a salty side-effect. Wastewater from oil drilling and hydraulic fracturing – or fracking – is often laden with salts and can spill, contaminating soils. In 2014, for example, 42 such brine spills per week, on average, were recorded in North Dakota. Brine spills introduce so ...

  • Innovative Uses of Compost Bioremediation and Pollution Prevention

    Each year agricultural effluents, industrial residues, and industrial accidents contaminate surface waters, soils, air, streams, and reservoirs. A new compost technology, known as compost bioremediation, is currently being used to restore contaminated soils, manage stormwater, control odors, and degrade volatile organic compounds (VOCs). Compost bioremediation refers to the use of a biological ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Dehalogenation

    Introduction: Contaminated soil is screened, processed with a crusher and pug mill, and mixed with reagents. The mixture is heated in a reactor. The dehalogenation process is achieved by either the replacement of the halogen molecules or the decomposition and partial volatilization of the contaminants. Base-catalyzed Decomposition (BCD) Base-catalyzed ...

  • A Citizen`s Guide to Chemical Dehalogenation

    What is chemical dehalogenation? Chemical dehalogenation is a chemical process to remove halogens (usually chlorine) from a chemical contaminant, rendering it less hazardous. Halogens are a class of chemical elements that include chlorine, bromine, iodine, and fluorine. Polychlorinated biphenyls are halogenated compounds that once were used in high voltage electrical transformers because they ...

  • Enhanced Bioremediation

    Introduction Enhanced bioremediation is a process in which indigenous or inoculated micro-organisms (e.g., fungi, bacteria, and other microbes) degrade (metabolize) organic contaminants found in soil and/or ground water, converting them to innocuous end products. Nutrients, oxygen, or other amendments may be used to enhance bioremediation and contaminant desorption from subsurface materials. ...
