Description:
Sub-slab sampling has become an integral part of vapor intrusion investigations. It is now recommended in guidance documents developed by EPA and most states. A method for sub-slab probe installation was devised in 2002, presented at conferences through 2005, and finally documented in a 2006 EPA report. The lengthy EPA report however discusses numerous quality assurance issues associated with sub-slab sampling and presents a method for discerning vapor intrusion using indoor air and sub-slab sample results. In this paper, information is extracted from the report to provide concise and specific recommendations on sub-slab probe installation that could be easily incorporated by regulators and environmental consultants into sampling plans for vapor intrusion investigations.
