Method for collecting a representative sub-slab sample

The MPCA has prepared a YouTube video illustrating step-by-step methods for collecting a representative sub-slab sample from beneath a building’s concrete floor. The video can be found on our Vapor Intrusion Best Management Practices webpage. Find it in the Investigation and Building Mitigation Decision Best Management Practices section.

If you have any questions related to the video or sub-slab sampling methodology, please call the MPCA Vapor Intrusion Hotline at 651-757-2040, or email vaporinfo.pca@state.mn.us.

Thank you!
