  • 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 ...


  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Engineered wetland removes subsurface hydrocarbons while providing beneficial reuse

    British Petroleum (BP) is operating an engineered wetland to treat petroleum-contaminated groundwater at a 300-acre site in Casper, WY. Release of petroleum products during refinery operations from 1908 until 1991 resulted in significant petroleum hydrocarbon contamination. Over 44,000 yd3 of LNAPL were removed by dual-phase recovery wells and oil/water separators constructed in 1981, but ...

  • Infrared differential absorption Lidar (DIAL) measurements of hydrocarbon emissions

    We report the application of an infrared (IR) differential absorption Lidar (DIAL) system (also capable of ultra violet measurements) built at the National Physical Laboratory (NPL), UK, to field measurements of total site emissions (controlled and fugitive) from petrochemical and landfill installations. The validation of the IR-DIAL was carried out via a series of controlled field experiments ...

  • 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 ...


  • Bioremediation with compost of a diesel contaminated soil: Monitoring by dehydrogenase activity and basal respiration

    The effect of compost on hydrocarbon degradation was determined during a 120-d incubation period. An evaluation of soil basal respiration and dehydrogenase activity as a monitoring instrument for the bioremediation process of soil contaminated with commercial diesel-oil was carried out. Six soil samples were used: S (control, uncontaminated soil), CS (contaminated soil), CSS (contaminated and ...

  • Historical and Retrospective Survey of Monitored Natural Attenuation Line of Inquiry Supporting Monitored Natural Attenuation and Enhanced Passive Remediation of Chlorinated Solvents

    Overview The Department of Energy (DOE) is sponsoring an initiative to facilitate efficient, effective and responsible use of Monitored Natural Attenuation (MNA) and Enhanced Passive Remediation (EPR) for chlorinated solvents. This Office of Environmental Management (EM) “Alternative Project,” focuses on providing scientific and policy support for MNA/EPR. A broadly representative working group ...


  • Combining HVME and Enhanced Bioremdiation for Gasoline Contamination in Groundwater.

    ABSTRACT A leaking underground storage tank at a commercial petroleum retail site located in Haskell, Texas resulted in soil and groundwater petroleum hydrocarbon contamination. This contamination, including benzene, toluene, ethylbenzene, and total xylenes (BTEX) and total petroleum hydrocarbons (TPH) migrated down-gradient below a road and neighboring property. Access below the adjacent roadway ...

  • LNAPL remediation using electrical resistance heating

    Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were discovered on an island in Ohio in May 1993 during the ...

  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...

  • Landfarming

    Introduction Landfarming is a full-scale bioremediation technology, which usually incorporates liners and other methods to control leaching of contaminants, which requires excavation and placement of contaminated soils, sediments, or sludges. Contaminated media is applied into lined beds and periodically turned over or tilled to aerate the waste. Soil conditions are often controlled to ...

  • Contamination/Environmental case study

    Orlando Drum Company, Orlando, FL Facility washes and reconditions used drums Mercuri and Associates, Inc. was retained as hydrogeological consultant to verify state allegations of contamination of soil and ground water with heavy metals, pesticides, and volatile organic compounds. Initiated preliminary soil and groundwater sampling program, prepared/submitted ...
