  • Biodegradation of total petroleum hydrocarbon (TPH) in Jordanian petroleum sludge

    Bioremediation, or the use of micro-organisms to decontaminate soil or groundwater, is being increasingly seen as an effective, environment-friendly treatment for oil-contaminated sites. In this study, the results are presented concerning a laboratory screening of several natural bacterial consortia and laboratory tests to establish the performance in degradation of hydrocarbons contained in oily ...

  • Incorporation of petroleum waste in clay ceramics and its characterisation

    In Brazil, the growth of the petroleum industry has resulted in an increasing amount of toxic oily wastes that have a high environmental impact. This work analyses the possibility of recovering waste from the petroleum industry using the powder technology route to produce clay-based ceramics. Batches of clay-petroleum waste mixes with up to 20 wt.% waste were prepared. The results showed that the ...

  • LNAPL At Petroleum Product Terminal - Case Study

    ABSTRACT BOS 200® was injected at a refined petroleum product terminal to remediate LNAPL in groundwater. Within one year after treatment, the site received a No Further Action status. CHALLENGES The remedial goal was to eliminate the reoccurrence of light non-aqueous phase liquid (LNAPL) which persisted with no apparent pattern. Annual ...

  • PETROTOX: An aquatic toxicity model for petroleum substances

    A spreadsheet model (PETROTOX) is described that predicts the aquatic toxicity of complex petroleum substances from petroleum substance composition. Substance composition is characterized by specifying mass fractions in constituent hydrocarbon blocks (HBs), based on available analytical information. The HBs are defined by their mass fractions within a defined carbon number range or boiling ...

  • Extractable Petroleum Hydrocarbons (EPH) method - Why it is important?

    Spills and releases of petroleum fuels are the largest source of environmental contamination in the United States. Massachusetts published a method that addresses the need to account for semi-volatile aliphatic and aromatic fractions of gasoline using gas chromatography (GC) analysis and a flame ionization detector (FID). This method was designed to measure the collective concentrations of ...


  • 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 ...

  • Rapid Analysis of Petroleum Hydrocarbons (TPH) in Soil and Water by Infrared Spectroscopy

    In 1988 the US EPA estimated that there were 3 to 5 million underground chemical storage tanks (UST’s) in the United States, of which up to 1% would develop leaks every year. In response to growing concerns about the quality and future availability of safe drinking water, federal and state programs have begun to systematically replace virtually all UST’s installed before 1986 either with above ...

  • Interpretation of total petroleum hydrocarbon (TPH) results with RaPID assay kits

    SUMMARY The SDI RaPID Assays for petroleum hydrocarbon fuels (Total BTEX, PAHs) have been shown to provide excellent correlation with GC based (8015M) and IR based (418.1) methodologies for testing Total Petroleum Hydrocarbons (TPH). Linear relationships between immunoassay and TPH results with both gasoline and diesel fuels are demonstrated. Fuel reactivities with immunoassay are shown to ...


  • Case study - EDRO in soil at petroleum tank farm site

    Environmental engineers needed quick and accurate screening analysis on a tank farm contaminated with a subsurface plume of fuel oil. Sitelab's EDRO test was performed to delineate the vertical extent of contamination. A drill rig was used to collect samples from the surface down to twenty feet at different locations throughout the property. They needed to quantify the size of the NAPL plume in ...

  • Classification of bacterial isolates of the Jordanian oil refinery petroleum sludge

    The aim of this study is to characterise the bacterial isolates of Jordanian oil refinery sludge for the purpose of using microorganisms in treating industrial wastewater effluents that contains hydrocarbons. Morphological, physiological, biochemical, antimicrobial susceptibility tests and 16S-23S rRNA spacer region polymorphism were used to characterise the isolated thermotolerant Bacillus, with ...

  • 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 ...

  • Enhanced Aerobic Bioremediation of Petroleum UST Releases in Puerto Rico.

    Abstract: Releases of petroleum compounds from underground storage tanks (USTs) containing diesel fuel and gasoline are a serious and increasingly prevalent problem in Puerto Rico. Remediation of groundwater impacted by these releases utilizing common methodologies can be quite costly and require long periods of time to implement. Oxygen is often the limiting factor retarding optimal ...

  • The real benefits of standardizing on a single LIMS in the gas and petroleum industry - Case Study

    Automation of laboratory data capture and analysis is claimed to be the major challenge facing the petrochemical industry. Indeed, elimination of manual processes leads to considerable product quality improvements while also aiding compliance with strict environmental regidations. As a result, companies that wish to remain ahead of the competition are standardizing on Laboratory Information ...

  • Surface Decontamination of Hydrocarbon Petroleum Distillates (Kerosene) by DeconGel 1101 and 1102

    Abstract Surface decontamination efficacy determination of DeconGel™ 1101 and 1102 on stainless steel, aluminum, and concrete surfaces contaminated with Hydrocarbon Petroleum Distillates (kerosene) was performed with GC/MS (Gas Chromatography/Mass Spectrometry) according to Environmental Protection Agency (EPA) SW-846 Methods: 3500C (sampling) and 8270C (analysis). ...

  • Oil in frac water testing

    The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the wa-ter. Waiting for remote laboratory results can take several days to a week. The InfraCal TOG/TPH ...

  • Portable IR Analyzers Provide Petroleum & Wastewater Industries with Accurate Oil Content Measurements

    Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on off-shore and on-shore drilling platforms for well over 45 years. U.S. EPA methods 418.1 and 413.2 were used extensively on a worldwide basis until the Montreal Protocol called for Freon (the solvent used in the analysis) to be phased out. Infrared analysis using tetrachloroethylene (perchloroethylene) is ...

  • What the Wastewater Industry can learn from the Petroleum Industry when it comes to measuring oil in water

    I recently read a comment in the Steve Jobs biography by Walter Isaacson that different divisions within a company do just what the name implies—divide a business.  Integration across and communication between the departments was essential to smooth functioning product.  I think the same is true in the analytical analysis/measurement world—there seems to be a divide in ...

  • Direct soil contact values for ecological receptors exposed to weathered petroleum hydrocarbon (PHC) fraction 2

    Ecological tier 1 Canada‐wide standards (CWS) for petroleum hydrocarbon (PHC) fraction 2 (F2; >nC10–C16) in soil were derived using ecotoxicological assessment endpoints (effective concentrations [ECs]/lethal concentrations [LCs]/inhibitory contrations, 25% [IC25s]) with freshly spiked (“fresh”) fine‐ and coarse‐grained soils. These soil standards might be needlessly conservative when applied to ...
