Vapor Pin Included in Michigan Vapor Intrusion Guidance

Cox-Colvin & Associates, Inc., in cooperation with the Michigan DEQ, completed a comparative study of sub-slab soil-gas sampling equipment to evaluate the Vapor Pin as an acceptable technology for vapor intrusion studies. The study demonstrated that samples collected through the Vapor Pin were consistent with those collected by other means. As a result, a SOP on the use of the Vapor Pin has been included as Appendix D.7 of Michigan DEQ's January 2012 Draft Vapor Intrusion Guidance - "Sample Collection and Evaluation of the Vapor Intrusion to the Indoor Air Pathway When the Generic Criteria Do Not Apply". (See p. 167 of the pdf for the Vapor Pin SOP).

Cox-Colvin is participating in a similar study in California in late April, in cooperation with H&P Mobile Geochemistry, Inc. Results of the Michigan and California studies are being submitted as a presentation topic at the October 2012 AWMA Conference in Denver, CO.
