How are the GORE® Modules deployed for subslab vapor sampling?
If the objective is to delineate the contaminant impact at depth, then the GORE® Modules should be inserted into narrow-diameter installation holes that extend to at least three feet below the slab and beneath any pooling of vapors under the slab. As with soil gas sampling, the module is secured by a string and cork. The hole can be covered with a bentonite patch for added safety and sample integrity in high traffic areas.
