Subject [SRRA] Change in indoor air & sub slab soil gas sampling requirements at VI investigations involving sensitive populations

The NJDEP is currently preparing a revised Vapor Intrusion Guidance document that will likely include numerous modifications to procedures for investigating and mitigating the vapor intrusion (VI) pathway. A draft copy of the revised document should be available for external review and comment shortly.

In August 2009, the Department implemented a procedural change that dealt with the concurrent collection of sub-slab soil gas and indoor air samples at buildings with sensitive populations. While the intention was to expedite VI investigations for people at potentially greater risk, the procedure created unseen technical problems that warranted further evaluation prior to implementation. Therefore, the policy has been modified.
