Abstract: We propose to develop a vapor flux sampling device, which we call a vapor flux meter (VFM), to evaluate vapor intrusion exposure risks. It will be self-enclosed and will include a permeable sorbent to retain chlorinated VOCs. The VFM will be placed in the headspace of a reservoir containing TCE or PCE spiked water. The experiment will be run for various times and the VFM will be extracted and the mass of chemical sorbed onto the sorbent will be measured using GC (according to Method TO-17) or by headspace analysis of the extract using a handheld photoionization detector (PID). The results of these experiments will be used to further develop VFMs to measure flux through porous media with varying moisture content.
