  • 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 ...

  • 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 ...

  • Field Application of a Lactic Acid Ester for PCE Bioremediation.

    ABSTRACT: As part of a strategy to enhance reductive dechlorination with a timed release of hydrogen, an application of glycerol polylactate (GPL) was made to a dry cleaner site contaminated with perchloroethylene (PCE). GPL is one of several proprietary lactic acid esters sold commercially as Hydrogen Release Compound (HRCTM). When HRC contacts the saturated contaminated zone, the lactic acid ...

  • 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 ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • On-Site TPH in Soil Measurements in less than 15 Minutes with Portable IR Analyzers

    On-site analysis of total petroleum hydrocarbon (TPH) concentration levels in soil are easily handled using the InfraCal TOG/TPH Analyzers manufactured by Wilks Enterprise, Inc.  The InfraCal TOG/TPH Analyzers are portable infrared (IR) analyzers that quickly determine TPH levels in less than 10-15 minutes, including the extraction.  Concentrations as low as 10 ppm to well over 10,000 - ...

  • Case study - TPH Oil & Grease applications

    These case studies illustrate the performance generated from customers who have used Sitelab’s UVF-3100 analyzer for testing total petroleum hydrocarbons in the C10 to C50 range. Sitelab’s TPH-Oil calibration kit is designed to correlate well to laboratory “Oil and Grease” test methods. This includes EPA Methods 1664 and 9071B by Gravimetric, EPA Method 418.1 by Infrared ...

  • Triad expedites brownfields redevelopment in Fairbanks

    The Fairbanks North Star Borough (FNSB) used Triad in 2006-2007 to assess environmental conditions at a municipal property along the Chena River in Fairbanks, AK. FNSB accelerated the site investigation as part of a brownfields assessment grant received from the U.S. EPA in 2005. Low-level contamination had been identified onsite in past investigations, but its extent and impact on future ...

  • Biodegradation of MTBE Utilizing A Magnesium Peroxide Compound: A Case Study.

    ABSTRACT: A patented magnesium peroxide compound was recently employed at an underground storage tank facility to increase the available oxygen in the groundwater for the biodegradation of fuel hydrocarbons. The objective of this remedial effort was to substantially reduce the dissolved-phase concentrations of BTEX and MTBE and to arrest further migration of the dissolved fuel hydrocarbon plume. ...

  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...

  • Assessment of the Environmental Impact of Military Activities During the Yugoslavia Conflict

    1. Executive Summary Assessment Method:The study was carried out over a period of ten days by a team of expert staff from the Regional Environment Center for Central and Eastern Europe (REC) and other contracted country experts. A framework was prepared by REC headquarters and the REC's country offices in the five selected countries gathered information and data. Additional ...
