  • Tech Tip: Deploying Sea-Bird CTD in Ice

    Large numbers of Sea-Bird conductivity instruments have been used in Arctic and Antarctic programs. Special accommodation to keep temperature, conductivity, oxygen, and optical sensors at or above 0° C is advised. Often, the CTD is brought inside protective doors between casts to achieve this. Conductivity Cell When freezing is possible, we ...

  • How To Handle Chemical Spills & Cleanups

    FAST-ACT is designed for liquid and vapor chemical releases, but the chemicals it attacks does not need to be limited to what we traditionally think of as a chemical spill. Toxic and noxious chemicals can come from a variety of sources such as waste water, decomposition, household chemicals, and animals. Since FAST-ACT can be applied to liquid spill or vapor release enabling Emergency Responders ...

  • Soil Vapor Extraction (In Situ)

    Introduction Soil vapor extraction (SVE) is an in situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semivolatile contaminants from the soil. The gas leaving the soil may be treated to recover or destroy the contaminants, depending on local and state air discharge regulations. ...

  • Solid H2S Removal System for Railcar Vapor Unloading Operations

    Molten sulfur is a basic component of many chemicals used in a variety of industries. It is typically brought into the chemical plant via tanker truck or rail car. Most molten sulfur comes from an industrial H2S removal process called the Claus Process, and contains dissolved H2S.

  • Thermally Enhanced Soil Vapor Extraction

    Introduction Thermally enhanced SVE is a full-scale technology that uses electrical resistance/electromagnetic/fiber optic/radio frequency heating or hot-air/steam injection to increase the volatilization rate of semi-volatiles and facilitate extraction. Thermally enhanced SVE is normally a short- to medium-term technology. Electrical Resistance Heating Electrical resistance heating uses ...

  • Contain Oil Vapor for Better Reliability

    In a boiler feed pump, an air breather is used to vent the enclosed air space on the bearing housings. With increasing heat and thermal expansion, oil vapors form in the bearing housings and migrate through the air vents. The vapor then condenses in the air filter media saturating the filter with oil. The air breather becomes ineffective, which affects mechanical seals and the overall ...

  • Vapor Steamers for Tile and Grout Maintenance

    Tile and grout cleaning is undoubtedly a tiresome and time-consuming job. Tiled floors are normally used in areas that experience heavy traffic. As a result, the floors can get quite dull and dirty at the end of the day. Then, there is the issue of grout, a highly porous surface that quickly absorbs dirt and develops stains. Rigorous scrubbing can wear away the grout and spoil its appeal. For ...

  • Andover, Vapor Extraction and Refrigerated Condensation Case study

    Vapor Extraction and Refrigerated Condensation was used as a primary source removal technology to remediate high concentrations of recalcitrant chlorinated solvent compounds at the WDE Site in Minnesota. The use of Refrigerated Condensation has achieved high mass removal rates and will reduce the lifecycle costs and time of remediation. History 6,600 drums of hazardous ...

  • Vapor Intrusion Issues Risk Occupants’ Health

    Vapor intrusion occurs when a gaseous substance migrates into a building.  For example, volatile organic compounds and other gases can migrate from contaminated soils and groundwater through cracks in foundations or sewer lines and enter a building.  Vapor intrusion can create an indoor environment that damages structural materials and puts building occupants’ health at ...

  • Chlorinated solvent soil vapor extraction (SVE) remediation case study 2005

    Project Description An active industrial facility in South Central Los Angeles was impacted by tetrachloroethylene (PCE) and trichloroethylene (TCE; former staging area degreasing) operations as a part of its operations. A phased approach to soil vapor extraction (SVE) remediation was employed: the goal of Phase I was to attain high contaminant mass removal rates with very high VOC vapor ...

  • Vapor intrusion mitigated through solar-powered exhaust systems

    EPA Region 6 undertook a Superfund removal action earlier this year at the Delfasco Forge site in Grand Prairie, TX, to address trichloroethene (TCE) vapor migrating from a groundwater plume. Region 6 and the State had determined after extensive site investigations that technologies such as soil vapor extraction or natural attenuation would require several years to remove or reduce the plume ...

  • Proposed plan offers tiering systems to determine preferred alternatives for vapor intrusion

    EPA Region 9 has issued for public comment a proposed plan to mitigate VI in commercial and residential buildings at the Middlefield Ellis Whisman (MEW) Study Area, which includes three NPL sites in Mountain View and Moffett Field, CA. Formerly used for industrial and semiconductor activities, this area has undergone extensive soil and groundwater remediation to remove TCE and other contaminants ...

  • 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 ...
