Gas phase sampling techniques and procedures used to assess an underground liquid hydrocarbon plume
- Radian Corp., Sacramento, CA (USA)
A site assessment was performed on the property adjacent to a major refinery. The objective of the assessment was to determine the nature and extent of all environmental impacts caused by the migration of contamination from the refinery. An underground liquid hydrocarbon plume originating from the refinery was discovered on the water table extending down gradient into a neighboring community. The liquid hydrocarbon plume resulted from spills and tank and pipe line leaks over years of petroleum refining. The technical approach developed for this assessment utilized gas phase sampling techniques to: identify the location of the liquid hydrocarbon plume; and identify and quantify the location of the soil-gas hydrocarbon plume and the effects of the soil-gas plume on public health. The assessment data were then used to design remedial actions to mitigate the environmental and public health impacts. This paper focuses on those gas phase sampling and analytical techniques used to assess the air contaminant pathway component of the environmental impact. According to the authors the gas phase sampling/analytical techniques and the technical approach presented can be used for a variety of applications in the management of underground storage tanks (UST) including leak detection, assessment of environmental impacts, and designing remedial actions for the mitigation of contaminant releases. The sampling and analytical techniques are presented, and the technical approach is described. Results of the soil-gas investigation are presented to illustrate the types of data generated using these techniques.
