Use of On-Site GC/MS Analysis to Distinguish between Vapor Intrusion and Indoor Sources of VOC

Abstract

Distinguishing between vapor intrusion (VI) and indoor sources of volatile organic compounds (VOC) is a significant challenge in site assessments, greatly increasing the cost and complexity of investigations. Rapid on-site analysis of indoor air samples using a portable gas chromatograph/mass spectrometer (GC/MS) allows the users to understand the distribution of VOC in real-time, supporting identification of the source while still in the field. The overall objective of the demonstration was to develop and validate a step-wise investigation procedure using commercially available off-the-shelf (COTS) on-site GC/MS analysis with real-time decision making as a tool to distinguish between VI and indoor sources of VOC.
