  • 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 ...

  • Manufactured gas plant investigation

    A two-person BEACON field team installed 304 PSG Samplers over a two-day period. Samplers were installed through soils, gravel, asphalt, and concrete. To accommodate field schedules, the Samplers were exposed for eight days in the field and the two-person field team required one day for retrieval of the Samplers. Survey results clearly showed where source areas are present on the site, as well as ...

  • Non-intrusive site investigation (UXO, CWM concerns)

    BEACON personnel used global positioning system (GPS) equipment to map out site locations. The soil-gas data clearly identified source areas of Trichloroethene (TCE) as well as other compounds of concern. The results showed the location of chlorinated contamination, which correlated well with data from a geophysical survey. While the flux chambers were in the field, more than nine inches of rain ...

  • Groundwater Plume, Source and Risk Identification Using Passive Soil Gas

    Abstract The results from sixty passive soil gas (PSG) samplers placed at a grain silo and mixed-use industrial facility with a known chlorinated solvent release aided with the rapid investigation time-schedule. The samplers were used to determine potential sources, plume extent and vapor risks in areas beyond the previous discrete soil sampling and permanent groundwater monitoring well ...

  • 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. ...
