the water “crowns” at the top of the vial. Cap the vial and invert 3 to 4 times to mix. (8) Invert the vial again to make sure no air bubbles are present. If a bubble is present open the vial and add additional tap water until a headspace-free sample is achieved. FINAL STEPS (1) Record the sampling date, time, site, and name of sampler on the bottle label and the Chain-of-
The monitoring port is coupled to a sampling pump used to withdraw the soil gas sample. Soil gas samples are periodically obtained and analyzed for the presence of VOCs. A system, method and apparatus for monitoring the subsurface at facilities for the presence of volatile organic compounds (VOCs).

The vial was then closed with a cap containing polytetrafluoroethylene (PTFE)-coated rubber septum and kept at 50 °C for 60 min. Headspace gas-chromatographic analysis was performed by manually injecting 1.0 mL of the vial headspace from each sample by means of a 1.5-mL Hamilton gas-tight syringe (temperature kept at 50 °C).
