USGS Scientists Collecting Gas Samples from the Unsaturated Zone at the Amargosa Desert Research Site, Nevada

USGS scientists collecting gas samples from the unsaturated zone. Subsurface gases are drawn through a small glass tube (in foreground hand) filled with adsorbing resins that trap volatile organic compounds (VOCs) for later analysis. Their findings suggest that VOCs may help explain radionuclide transport at the site.
