  • 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. ...

  • Mobilization assessment and possibility of increased availability of PAHs in contaminated soil using column tests

    Surfactants are well known to increase solubility/mobility of hydrocarbons and can be used to remediate contaminated water and soil. We wanted to explore if Ivey sol R   106 used at less than the critical micelle concentration (CMC) could effectively mobilize PAH (polycyclic aromatic hydrocarbons) from contaminated soil. The first step was to establish a measurement technique. Hence, a ...

  • The potentiation of zinc toxicity by soil moisture in a boreal forest ecosystem

    Northern boreal forests often experience forest dieback as a result of metal ore mining and smelting. The common solution is to lime the soil which increases pH, reducing metal toxicity and encouraging recovery. However, in certain situations, such as Flin Flon, Manitoba, Canada, liming has only yielded moderate benefits with some locations responding well to liming and other locations, not at ...

  • Case study - EPH in soil with diesel and home heating oils

    Sitelab’s UVF-3100 analyzer is a popular tool when excavating soils contaminated by fuel oils from underground storage tanks (USTs). These studies show the accuracy testing samples for Extractable Petroleum Hydrocarbons, EPH C11- C22 aromatic hydrocarbons. Samples are extracted in solvent using test kits and measured on the UVF analyzer’s EPH optics, calibrated to Sitelab’s PAH ...

  • Effect of amendment on phytoextraction of arsenic by Vetiveria Zizanioides from soil

    Abstract: The present study was undertaken to evaluate the growth response of Vetiveria zizanioides amended with organic amendments to arsenic (As) in contaminated soils and its ability to sequester As. The test results indicate that the plants exhibited high tolerance to As in the soils and their normal growth continued even though As concentration reached 500 mg/kg. However, when As ...

  • TCE Hot Spots have California Residents Concerned

    For years, many people living near the Moffett Federal Airfield by Mountain View, California, have had concerns over toxic chemicals known to be in the soil and groundwater in the area. After a recent report by the U.S. Environmental Protection Agency (EPA), some residents now admit to being scared. The EPA has found higher than expected levels of trichloroethylene, also known as ...

  • Biopiles

    Biopile treatment is a full-scale technology in which excavated soils are mixed with soil amendments and placed on a treatment area that includes leachate collection systems and some form of aeration. It is used to reduce concentrations of petroleum constituents in excavated soils through the use of biodegradation. Moisture, heat, nutrients, oxygen, and pH can be controlled to enhance ...

  • Accumulation and toxicity of metals (copper, zinc, cadmium, and lead) and organic compounds (geraniol and benzo[a]pyrene) in the oribatid mite Oppia nitens

    The oribatid mite Oppia nitens has been suggested as a test species for ecotoxicological assessment of contaminated boreal soils. Knowledge of the ecotoxicity of pollutants of different modes of action to this species is necessary to assess its relative toxicity to other invertebrates. The toxicity of four metals and two organic chemicals to O. nitens was evaluated over a 28‐ or 35‐d period. Mite ...

  • Case Study: Basford Gasworks Remediation Project, Nottingham

    The soils washing installation now owned and operated by HBR was formerly used by Kinatex Heijmans Joint Venture to process contaminated soil at the Basford Gasworks site. The project was the first major land based application of soils washing technology in the UK with in excess of 150,000 tonnes of soil successfully processed. Treatability Phase In the autumn of 1996, LHJV were contracted by BG ...

  • Separation

    Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

  • 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 ...

  • Sulphate reducing bacteria to precipitate mercury after electrokinetic soil remediation

    Combined treatment with electroremediation and sulphate reducing bacteria (SRB) was tested in laboratory and pilot scale. The contaminated soil came from a chlor-alkali factory and contained about 100 mg/kg Hg. Iodide/iodine complexing agent was used to mobilize mercury. Mercury iodide complexes were moved to the anode solution using an electric field. The anode solution was then mixed with ...

  • Can I extend the range of the TPH in Soil kit by dilution?

    The pocket colorimeter kit by Hach offers an immunoassay method to measure TPH (Total Petroleum Hydrocarbons) in soil samples – a useful indicator of petrol pollution or contamination in soil. For areas of heavy contamination the range of the test can be extended by dilution during the soil extraction step. ...

  • Soil Contamination and Possible Threats to Human Health

    In 2007, the city of Salisbury, North Carolina, purchased a piece of land that was the location of a former service station. The property had been given a clean bill of health in 1991 and again in 2007 just before the property was purchased. Last year, the city began site preparations to build a new central office for the local schools when soil contamination was found. It turns out ...

  • An investigation and remediation of TNT contaminated soils.

    An investigation and remediation of TNT contaminated soils and wastes was conducted at the Apache Powder Superfund Site in Cochise County, Arizona during 1999 and 2000. TNT contamination was most likely the result of salvage operations of World War I munitions. Characterized by a steep hillside and arroyo cutting through the wastes, the site offered challenges of stability, access, health and ...

  • Deadly Hexavalent Chromium in Soil

    Merging technologies will change over Hexavalent Chromium in soil to Trivalent Chromium, effectively stopping Hexavalent Chromium from becoming dangerously airborne or becoming even more deadly by migrating into the water table. There are three valences of Chromium: 1) Chromium—safe to humans, 2) Trivalent Chromium—safe and an essential element in humans and 3) Hexavalent ...

  • Other Treatment Technologies

    Reuse/Recycle: Recovery and reuse technologies for energetic materials, including both explosives and propellants, should be considered at explosives waste sites for several reasons. First, new recovery methods and potential uses for reclaimed explosive materials are rapidly developing. Second, recovery/reuse options reduce overall remediation costs by eliminating destruction costs and allowing ...

  • Case study - GRO in soil at gasoline UST site

    These case studies show the performance using Sitelab’s UVF-3100 analyzer testing gasoline range organic hydrocarbons.  This includes benzene, xylene, BTEX and other volatile petroleum compounds in the GRO or VPH C6 to C10 hydrocarbon range. When calibrated using Sitelab's GRO calibration kit (CAL-025), the UVF analyzer produces test results that correlate well to laboratory ...

  • Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

    ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...
