  • 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 ...

  • Evaluation of Sorbent Methodology for Petroleum-Impacted Site Investigations

    Abstract Soil gas measurements are often used for risk assessment in vapor intrusion investigations. In the case of petroleum-contaminated sites, total petroleum hydrocarbon (TPH) characterization may be required to effectively measure the associated risk. One of the common strategies employed to characterize TPH for risk assessment includes the quantitation of indicator compounds of ...

  • Green remediation best management practices: site investigation

    Overview The need for site investigation is common to cleanups under any regulatory program. An investigation can occur at all points in the cleanup process, from initial site assessment through waste site closeout. A site investigation generally is undertaken to: Confirm the presence or absence of specific contaminants Delineate the nature and extent of environmental contamination ...

  • Comparison of Eight Innovative Site Characterization Tools Used to Investigate

    Environmental assessment of contaminated sites often requires delineation of the pathways of contaminant migration. Often, the pathways are strongly affected by the subsurface geology. At Vandenberg AFB in California, an accidental release of gasoline containing MTBE occurred at a base gasoline station in 1994. Dissolution of the gasoline into groundwater has created a dissolved MTBE plume at ...

  • Radiological Evaluation of contaminated sites and soils VEgAS: an expertise and investigating vehicle

    Summary 1- Fontenay-Aux-Roses CEA Clean-up methodology For the denuclearisation of the first French nuclear research centre (CEA), the centre of Fontenay-aux-Roses started developing in 1999 a clean-up methodology to rehabilitate places that have been contaminated by radioactive materials. The structure of this methodology is comparable to the one that the ...

  • Evaluation of Spatial and Temporal Variability in VOC Concentrations at Vapor Intrusion Investigation Sites

    ABSTRACT As vapor intrusion has become an increasing concern at corrective action sites, the USEPA and a number of state regulatory agencies have recently issued guidance documents covering the collection of subsurface gas, and above-ground air samples during vapor intrusion investigations. Most of these guidance documents do not provide specific recommendations concerning the number of each ...


  • Single field mobilization completes site investigation and removal actions

    The Kentucky Research Consortium for Energy and the Environment (KRCEE) worked with the U.S. Department of Energy (DOE) last summer to introduce new approaches and technologies to the site cleanup program operating at the Paducah Gaseous Diffusion Plant (PGDP) in western Kentucky. A Triad demonstration was conducted at PGDP's Area of Concern (AOC) 492 that integrated several real-time ...

  • Superfund Compliance Review - Document/site review and investigation - Case Study

    Midwestern US The Summary We provided expertise in determining if previously closed waste management units and ongoing remediation efforts at an oil facility were and are being conducted in a manner consistent with applicable provisions of the federal Superfund program and the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). ...

  • X-Ray Radiographic Investigation of Perchloroethylene Migration at the Livingston Derailment Site

    X-ray radiography of soil cores was used as the primary test method to determine the reasons for the permeation of perchloroethylene into apparently impermeable clay layers at a hazardous chemical spill site. X-ray powder diffractometry, scanning electron microscopy, and chemical analysis were also performed to characterize the materials and structures observed in the soil cores through X ...

  • Assessment of geo-hazard potential and site investigations using Resistivity Imaging

    The use of geophysical methods for evaluating subsurface contamination of sites is becoming increasingly popular all over the world. The paper presents the assessment of geo-hazard potential of a site in the City of Duncanville, Texas using Resistivity Imaging (RI). Resistivity Imaging was being used to identify areas of environmental concern and to develop a detailed image of subsurface ...

  • 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 ...

  • Environmental forensics investigation

    Location: Vancouver, BC Owner: Confidential Description: Environmental forensics investigation ongoing to determine the source of chlorinated solvents (PCE, TCE, 1,1,1-TCA1,1,DCE) and 1,2-dichlorobenzene contamination at a site that has changed owners in the past 25 years.
