  • Analytical Testing for Corexit Dispersants Used in the Gulf Spill

    The analysis of various sample matrices (seawater, sediment, tissue) to determine concentrations of Corexit dispersants used in the Gulf spill requires the use of one or more of the components in the dispersant as a tracer. The primary active ingredient (i.e. the primary surfactant) in the Corexit products is Dioctyl Sulfosuccinate Sodium Salt (DOSS). The other primary ingredients function as ...


  • Effects of chemical dispersant and seasonal conditions on the fate of spilled oil – modelling of a hypothetical spill near Saint John, NB

    The proposed Energy East pipeline project has raised concerns about potential oil spills in Saint John, New Brunswick. While environmental conditions could pose challenges for using mechanical recovery methods if a spill occurs, chemical dispersant could be an alternative. However, the application of chemical dispersant in shallow water and costal zones remains an issue of debate. Furthermore, ...

  • Bioremediation of an Oil Spill

    Bioremediation is the method of choice to effectively clean up a small spill of hydrocarbons. In this case, five-hundred liters of BTEX has spilled from an above ground storage tank into a pasture that is located at the west edge of the Royal Roads University (RRU) grounds. The soil is classified as a Gleyed Eutric Brunisol based on recent laboratory analysis; it contains clay, but is fairly ...


  • Oil Spill Technologies Heat Up

    The highly successful, widespread deployment of PyroBoom® fireboom for controlled burning in the Gulf represented a crowning achievement in a development journey spanning more than 30 years. The concept of burning spilled or leaked oil on the sea’s surface has been known for many years, offering an extremely effective way of reducing the spill by as much as 90 percent with minimal ...

  • Air Monitoring for the Gulf Oil Spill

    Ambient air monitoring is a priority in the ongoing efforts to contain and manage the oil spill from the Deepwater Horizon in the Gulf of Mexico. The following provides information about the kinds of airborne contaminants that are currently being monitored in the Gulf, how they are collected and how they are analyzed. For a given project, a suitable sampling plan – developed by ...

  • Offshore oil spill clean up case study

    In the event of a major incident occurring offshore, for example a tanker casualty running aground or breaking up for any reason, it is of paramount importance to deploy emergency response to protect and save human life. Once this has been done an assessment of the casualty should be made on whether it is possible to salvage the vessel and its contents and to assess the type and amount of oil ...

  • Case Study - BP oil spill bioremediation tests

    CL Solutions, LLC has completed some internal preliminary testing of Munox SR® at the request of our customers and regulators in the Gulf Region. Although, our products have been used to remediate soil and ground water at numerous locations in the region, these tests were undertaken to verify specific applicability to the BP spill. Tar Ball Treatment While manual removal of ...

  • Groundwater Remediation System Cleans Up Oil Spill

    A customer in TX was recently in some hot water with the local municipal water department. Due to excessive rains near the coast of Texas, the water levels have been higher than usual. The company fills storage tanks with diesel at its facility. However one day the tanks were overfilled and instead of going into the ground, they diesel dispersed out via the high rain water and into the local ...

  • Effects of dispersed oil on reproduction in the cold water copepod Calanus finmarchicus (Gunnerus)

    Following a 120 hours exposure period to three concentrations of oil dispersions (0.022, 1.8 and 16.5 mg L−1 + controls) generated from a North Sea crude oil, and a subsequent 21 days recovery, mortality and several reproduction endpoints (egg production rates, egg hatching success, fraction of females participating in reproduction) in Calanus finmarchicus were studied. Concentration‐dependent ...

  • Oil Spill Eater, Solution Oil Spillage in Niger Delta

    Oil Spill Eater II is the name of a non-toxic product which provides the means for moving oil spill response out of its 19th Century methodology into the realm of advanced technological 21st Century breakthroughs for addressing and remediating 100% of any spill in any environment.  In comparison, current response methods employed by three major oil companies - BP, Exxon and Shell - are ...

  • Dispersant and salinity effects on weathering and acute toxicity of South Louisiana crude oil

    Chemical dispersants are an important technology in the remediation of oil spills in the aquatic environment, facilitating degradation of crude oil and salinity is an important factor in dispersant effectiveness. The aim of the current study was to explore the role of salinity on the degradation chemistry of crude oil polycyclic aromatic hydrocarbons (PAH) and acute toxicity of the water ...

  • Tri Parish Times OSE II oil spill clean up

    OSE II can prevent illness suffered from the use of dispersants. OSE II has been demonstrated over 11 times on the BP spill and successfully tested by BY for their Deep Water Horizon Spill. OSE II has proven to remediate not only the oil by the toxic dispersants BP used on the spill to sink the oil. OSE II has proven in front of news camera's to be capable of removing BP spilled oil from sandy ...

  • Biosurfactant produced by a Rhodococcus erythropolis mutant as an oil spill response agent

    Biosurfactants have been considered as superior alternatives to currently used surfactants as they are generally more biodegradable, less toxic, and better at enhancing biodegradation. However, the application of biosurfactants is limited by the availability of economic biosurfactants and the corresponding producers that can work effectively. Hyperproducers generated by metabolic engineering ...

  • Rational application of chemicals in response to oil spills may reduce environmental damage

    Oil spills, for example those due to tanker collisions and groundings or platform accidents, can have huge adverse impacts on marine systems. The impact of an oil spill at sea depends on a number of factors, such as spill volume, type of oil spilled, weather conditions, and proximity to environmentally, economically, or socially sensitive areas. Oil spilled at sea threatens marine organisms, ...

  • Ecological Significance of Residual Exposures and Effects from the Exxon Valdez Oil Spill

    An ecological significance framework is used to assess the ecological condition of Prince William Sound (PWS), Alaska, USA, in order to address the current management question: 17 y following the Exxon Valdez oil spill (EVOS), are there any remaining and continuing ecologically significant exposures or effects on the PWS ecosystem caused by EVOS? We examined the extensive scientific literature ...

  • Toxicity of crude oil chemically dispersed in a wave tank to embryos of Atlantic herring (Clupea harengus)

    Tests of crude oil toxicity to fish are often chronic, exposing embryos from fertilization to hatch to oil solutions prepared using standard mixing procedures. However, during oil spills, fish are not often exposed for long periods and the dynamic nature of the ocean is not easily replicated in the lab. Our objective was to determine if brief exposures of Atlantic herring (Clupea harengus) ...

  • Study of the dispersion/settling of oil–mineral–aggregates using particle tracking model and assessment of their potential risks

    A random walk particle tracking model was used to simulate the motions of oil–mineral–aggregates (OMAs) under hydrodynamic conditions involving wave–induced velocities, random velocities due to turbulence, and the settling velocity due to gravity. Wave–induced and settling velocities for OMAs determined from the application of Stokes's theory and empirical equations derived from experimental data ...
