Step 1
While wearing PPE, drill a 5/8-inch diameter hole through the slab and approximately 1-inch into the underlying soil to form a void.
Step 2
Keep up on dust management with a Wet/Dry Vacuum. HEPA filter optional.
Step 3
Brush the hole with the bottle brush and remove the loose cuttings with the vacuum.
Step 4
Assemble the Vapor Pin® Sampling Device and place the lower end of the Vapor Pin® into the drilled hole.
Step 5
Place the small hole located in the handle of the Installation/Extraction Tool, over the Vapor Pin® to protect the barb fitting and tap the Vapor Pin® into place.
Step 6
Place the Vapor Pin® Cap on the Vapor Pin® to prevent vapor loss prior to sampling.
Step 7
Allow 20 minutes or more (consult applicable guidance for your situation) for the sub-slab soil-gas conditions to re-equilibrate prior to sampling.
