Active Manufacturing Facility Soil Vapor Intrusion Investigation
Triad Environmental Solutions, Inc. (TES) was contracted by AECOM, Inc. to provide Triad characterization support for the investigation of potential soil vapor intrusion into a large building (>20 acre) housing an active manufacturing facility in New York state.  During 3.5 days of field activities, 109 discrete sub-slab soil vapor sampling points were located, installed, sampled and analyzed on-site in real-time.  Using the DSITMS with the Triad approach, numerous sources for potential soil vapor intrusion were identified, mapped and the aerial extent of the sub-slab soil vapor sources were determined.
