Pennsylvania Guidance Update



Acceptance of the Vapor Pin noted on Page 97 in the Updated PA VI Guidance Document

Land Recycling Program TGM Section IV: Vapor Intrusion Guidance “Some manufacturers offer alternative sub-slab soil gas sampling point equipment that relies on driving (hammering) a specialized barbed-metal fitting into the slab penetration.The metal fitting is sealed inside the slab penetration by the compression of a sleeve of flexible tubing between the fitting’s barbs and the sidewalls of the penetration. These “hammer-in”points may be considered for use during VI investigations.” – Page 97
