摘 要：The objective of this project, was therefore, to develop a prototype sensor technology, membrane-extraction (ME)-IMS, that could be used in situ or ex situ, to characterize the extent of groundwater plumes, conduct compliance monitoring around waste facilities or at the leading edge of a plume, and monitor remedial actions. The IMS instrument could also be used to monitor CHC in the vapor phase.
