  • 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 ...

  • 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 ...

  • Detection and Location of Leaks in Geomembrane Liners Using an Electrical Method: Case Histories

    ABSTRACT A field-proven electrical technique, developed at Southwest Research Institute, San Antonio, Texas, is commercially available to detect and locate leaks in geomembrane liners. The electrical technique is used to inspect 100% of the geomembrane material that is covered by a conducting liquid. A voltage applied across the liner produces a uniform electrical potential distribution in ...

  • 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 ...

  • Void Formation , what CCTV doesn`t show

    A Brief Overview of Cavity Formation and Investigation in Drainage Pipes. CCTV investigation is used to assess structural condition of drainage pipes. Major faults and Breaks are relitively easy to identify , however CCTV does not show what is present around the pipe. Many major defects are caused by small pipe defects resulting in soil migration leading to major void formation and ...

  • 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. ...

  • Assessment of the effect of slope on runoff potential of a watershed using NRCS–CN method

    The rainfall–runoff is a very complex hydrological phenomenon, as this process is highly non–linear, time–varying and spatially distributed. The average slope within the watershed together with the overall length and retardance of overland flow are considered to be the main factors which govern the runoff process. The Natural Resources Conservation Service curve number (NRCS–CN), formerly known ...
