Abstract: The losses of trichloroethylene (TCE) from soil samples transferred to and from a storage bottle were evaluated by comparing them to values obtained using a method that limits sample disruption and exposure and prevents vapor losses from a subsample after a single transfer step. The results strongly suggest that volatile organic compounds (VOCs) are readily lost from contaminated soils when care is not taken to limit surface area exposure and prevent vapor loss. For this site investigation and others using similar sample handling protocols, VOC losses are most abundant during field collection operations and storage. The magnitude of the VOC losses during these two steps far exceeds those anticipated when a subsample is transferred from these storage bot tles prior to off-site laboratory analysis.
