Six commercially-available portable gas chromatographs (PGC) were evaluated at a Superfund site during startup of bioremediation. Concentrations of volatile organic compounds (VOC) were slightly above ambient background levels. Concurrent colocated grab samples were collected periodically in Summa-polished canisters. They were analyzed by Method TO-14 using a mass-sensitive detector. The grab samples served as standards to assess the accuracy of data reported by the PGCs.
