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.

EPA Releases Vapor Intrusion FAQs

EPA recently posted Vapor Intrusion FAQs (frequently asked questions) on its Vapor Intrusion (VI) website. This 56-page document is much more than the average fact sheet, and provides a preview of what the much anticipated final VI guidance is likely to look like. Read More>>

Cox-Colvin to present on Innovative Subslab Soil-Gas Sampling Methods

Cox-Colvin employee Mort Schmidt will be presenting at A&WMA's 'Air Quality Measurement Methods and Technology' Conference to be held April 24 - 26, 2012 in Durham, North Carolina.  Mort will be presenting his talk, entitled "Innovative Sampling Methods for Focusing the Subslab Soil-Gas Investigation" on Wednesday, April 25th @ 2:45 pm (Session 7A). Mort's presentation will highlight an investigation in which Cox-Colvin installed and sampled 145 sub-slab soil gas sampling points in five days to locate a source of tetrachloroethene at a manufacturing facility.

Cox-Colvin also will be exhibiting the Vapor Pin at the conference.  Join us at Booth #19 to learn more about the Vapor Pin - a re-usable sub slab vapor sampling device.
