Soil Gas Sampler Eliminates Leaks

摘要

The Vapor Pin is a new sampling device that reduces the cost and improves the quality of sub-slab soil gas investigations used tolocate contaminant sources beneath buildings and to, conduct vapor intrusion evaluations. It can be installed quickly and easily, and its unique, patented design eliminates the need for grout or other adhesives. A small-diameter hole is drilled through the slab and the Vapor Pin is put in place using an installation/extraction tool and a hammer. Because the Vapor Pin is machined from a single piece of metal, the potential for leaks is essentially eliminated. At the end of an evaluation, the sampler can be removed for reuse, further lowering the cost to implement such studies.
