  • Measurement of naphthenic acids in the receiving waters around an offshore oil platform by passive sampling

    Polar organic chemical integrative samplers (POCIS) were deployed in the vicinity of an offshore oil installation and analysed for naphthenic acids (NA). POCIS accumulated a range of mono to tetracyclic NA, with different degrees of alkylation, with monocyclic acids being the most abundant. POCIS or similar polar samplers may currently be the only way to measure exposure to NA from offshore ...

  • Dry cleaner investigation

    A BEACON Passive Soil-Gas (PSG) Survey was performed at a dry cleaner site in the southeastern United States to determine if Tetrachloroethene (PCE) contamination identified beneath the dry cleaner in a prior BEACON PSG Survey was migrating off site and, if so, in which direction it was moving. This survey involved 30 field samples collected in a grid pattern. Analytical results were provided to ...

  • Chlorinated plume investigation

    The initial survey of the AOC identified a source area of Trichloroethene (TCE) and the direction the plume was migrating in the groundwater. Three subsequent surveys were performed to identify additional source areas and to delineate the lateral extent of the plume, which was much greater than the client expected. The client's overall project costs were reduced significantly by effectively ...

  • Petersburg airport improvements - Case Study

    Semi-Passive Treatment with ChitoVan Chitosan Lactate Cartridges Dungeness Environmental was called upon to assist with passive treatment using ChitoVan Chitosan Lactate Cartridges at an Airport Safety Improvement project in Petersburg, Ak in March of 2009. The project consisted of expanding the runway to meet FAA and RSA design standards. In the process multiple culverts were replaced which ...

  • The Kansas City, Missouri, Ground-Level Ozone (GLO) Project: A Community-Based Air Pollution Field Experiment

    Tropospheric ozone concentrations for Kansas City are well known on a regional scale. The Kansas City, Missouri, ground-level ozone (GLO) project measured outdoor ozone concentrations using passive sensing devices (PSDs) on a neighborhood scale. Highly resolved exposure maps were made based on the detailed air quality observations collected during the seven week sampling study during the summer ...

  • Passive sampling coupled to UV irradiation: A useful analytical approach for studying oxygenated polycyclic aromatic hydrocarbon formation in bioavailable mixtures

    We investigated coupling passive sampling technologies with ultraviolet irradiation experiments to study polycyclic aromatic hydrocarbon (PAH) and oxygenated PAH (OPAH) transformation processes in real‐world bioavailable mixtures. Passive sampling device (PSD) extracts were obtained from coastal waters impacted by the Deepwater Horizon oil spill and Superfund sites in Portland, OR. OPAHs were ...

  • PCDD/F release during benthic trawler‐induced sediment resuspension

    Benthic trawling can cause the resuspension of large amounts of sediments. Such regular practice in the Grenland fjord system in the south of Norway has the potential to affect the fate, movement, and bioavailability of sediment‐associated polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs). A novel mode of exposing passive sampling devices consisting of towing semipermeable membrane ...

  • Application of Passive Soil Gas Technology to Determine the Source and Extent of A Pce Groundwater Plume in an Urban Environment

    Abstract In situations where groundwater supplies have been impacted by volatile organic compounds, such as perchloroethylene (PCE,) and the source has not been identified, the costs to identify the source and plume migration patterns may be extremely high. The costs for an investigation increase with the number and depth of borings and the number of samples that are collected and analyzed. ...
