Application of a passive soil vapor survey at a former manufactured gas plant
- W.L. Gore and Associates, Inc., Elkton, MD (United States)
Manufactured gas plants (MGPs) operated from the mid-nineteenth century to the 1950`s, producing wastes characterized by tars and oils comprised of compounds including volatile organic compounds (VOCs) and polynuclear aromatic hydrocarbons (PAHs). Active soil gas methods have been used at MGP sites to help locate these wastes in soil and ground water as part of initial site investigations. However, active methodology is generally limited to detection of only the volatiles present, while passive methods have shown limited success at MGP sites. A new passive soil vapor survey has been developed and validated over the past two years which helps to address these limitations. By using a time-integrated approach and a unique soil vapor collector the GORE-SORBER{reg_sign} Screening Survey has proven to successfully detect PAH compounds as well as volatiles. This technology features a patented, passive sorbent collector constructed from GORE-TEX{reg_sign} expanded polytetrafluoroethylene (ePTFE), which allows for efficient vapor transfer from the subsurface to the adsorbent, but prevents liquid water and particulate from impacting sample integrity and sensitivity. This discussion describes the unique qualities of this passive soil gas technology and presents the results of a recent application at a former MGP site in the eastern United States with comparison to the results from previous soil and ground water investigations conducted at the site.
