  • Case study - Texas crude oil in soil sites

    Sunset Well Service, Inc. is an environmental contractor located in the Midland/Odessa area of Texas. They use their UVF-3100D analyzer to help excavate and remediate soils contaminated by produced water and crude oil. Laboratories in Texas test TPH using the TX 1005 GC-FID Method. This method is similar to U.S. EPA Method 8015M, but reports the GRO, DRO and ORO fractions separately. Soils from ...

  • Effect of OSE(II)-Enhanced Soil Washing(OESW) for TPH -Contaminated Soil Remediation

    The objectives of this study were to perform potentially suitable active agent that solubilize total petroleum hydrocarbon (TPH) present as contaminants and to evaluate the optimal range of process parameters that can increase the removal efficiency in OSE(II)-enhanced soil washing (OESW) pilot tests. Used experimental method for solubilisation of TPH by using OSE(II) was batch experiments. The ...

  • 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. ...

  • Acute toxicity of chemically and mechanically dispersed crude oil on juvenile sea bass (Dicentrarchus labrax): Absence of synergistic effects between oil and dispersants

    The goal of this experiment was to assess the relative acute toxicities of mechanically and chemically dispersed oil (Crude Arabian Light) in controlled conditions. Juvenile sea bass (Dicentrarchus labrax) were exposed to four commercial formulations of dispersants (Corexit EC9500A, Dasic Slickgone NS, Finasol OSR 52, Inipol IP 90), to mechanically dispersed oil and to the corresponding ...

  • Temporal changes in the sensitivity of coastal Antarctic zooplankton communities to diesel fuel: A comparison between single‐ and multi‐species toxicity tests

    Despite increasing human activity and risk of fuel spills in Antarctica, little is known about the impact of fuel on Antarctic marine fauna. The authors performed both single‐ and multi‐species (whole community) acute toxicity tests to assess the sensitivity of an Antarctic coastal zooplankton community to the water‐accommodated fraction of Special Antarctic Blend diesel. Single‐species tests ...

  • Remediation of refinery waste, oil sludge from lagoons and contaminated soils - case study

    The first VacuDry plant installed at a refinery is designed to treat waste which has accumulated over the last decades, as well as waste that will be generated inside the refinery in the future. The semi-mobile system has a capacity of 1.5 to 2 tons per hour. The plant is designed for maximum flexibility and can treat different types of refinery wastes ranging from dry soil to wet centrifuge ...

  • Performance assessment of pilot horizontal sub-surface flow constructed wetlands for removal of diesel from wastewater by Scirpus grossus

    One of the appropriate development technology options for the treatment of wastewater contaminated with diesel is constructed wetlands (CWs). Throughout 72 days of exposure, sampling was carried out for monitoring of physical parameters, plant growth and the efficiency of total petroleum hydrocarbon (TPH) removal, as an indication for diesel contamination, to assess the pilot-scale performance. ...

  • Pilot Project at Tidewater Terminals

    The pilot project was undertaken to determine the effectiveness of AgroRemed for cleanup of contaminated soil within a short turn around time as claimed by SARVA. The results were monitored on 10th day and 20th day before closing the pilot. It is seen from the results that there was a reduction of more than 30% in the values of TPH on 10th day and at the end of 20 days there was a reduction in ...

  • Residential spill in VA

    Laboratory analysis of soil samples showed high values of TPH/DRO showing an initial value of 18,800 and 8,300 ppm and the samples of soil analyzed after treatment with VaporRemed showed a value of 290 ppm and 210 ppm. Both these values are below the stipulated 500 ppm of TPH/DRO. The TPH in the drain water after flushing with the product showed values below the detection levels. The project was ...

  • Restoration of Vegetation Affected By Diesel Spill

    The toxicity of diesel spill was reduced facilitating healthy growth of grass and other vegetation at the site. TPH of the soil was reduced from 65,000 ppm to less than 1000 ppm by on site application. Restoration of vegetation and reduction of toxicity of spill using AgroRemed was achieved at a cost of less than $ ...

  • Matching Oil in Water Analyses with Regulatory Methods - Case study

    When analyzing oil and grease in water while out in the field, it is important to use an EPA approved method and equipment. While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, ...

  • Investigation of the toxicokinetics of petroleum hydrocarbon distillates with the earthworm Eisenia andrei

    The Canada‐Wide Standards for Petroleum Hydrocarbons in soils regulate petroleum hydrocarbons based on four distillate ranges: F1 (C6–C10), F2 (>C10–C16), F3 (>C16–C34), and F4 (>C34). Previous toxicity tests with earthworms and F2, as well as two subfractions of F3, F3a (>C16–C22) and F3a (>C22–C34), indicate that test durations might not be sufficiently long to reach threshold effect ...
