Cox-Colvin Announces Commercial Release of the Vapor Pin™ - An Innovative Sub-slab Soil Gas Sampling Device

Cox-Colvin proudly announces the commercial release of the Vapor Pin, a patented, reusable sub-slab soil-gas sampling device that eliminates many of the frustrations associated with traditional sub-slab vapor sampling methods. Because of its ease and speed of installation, sample collection, extraction, and reuse, we believe the Vapor Pin will become the new standard for sub-slab soil gas sampling.

Cox-Colvin to present posters at RemTEC Summit 2011

Two Cox-Colvin & Associates Principal Scientists are heading to Chicago this week to present posters at the RemTEC Summit 2011 on May 17 - 19. George Colvin, Vice President of Cox-Colvin, will present a poster titled "Benefits of Incorporating GSR Concepts into an Inherently Less Green and Sustainable Alternative: Case Study on a HVDPE System". Craig Cox, President of Cox-Colvin, will present a poster titled "Methods for Dissecting Large Commingled VOC Plumes".

C0x-Colvin also will be exhibiting at RemTEC Summit 2011. Visit us at Booth 59 and check out the Vapor PinTM - Cox-Colvin's new innovative sub-slab vapor sampling device!

Additional Labs VAP-Certified for Cis-DCE in Air

In August of last year our newsletter discussed the fact that only one lab was certified to analyze cis-1,2-dichloroethene (cis-DCE) in air under Ohio’s Voluntary Action Program (VAP). Cis-DCE is a breakdown product of tetrachloroethene (PCE) and trichloroethene (TCE),which are present at more than half of all RCRA sites, and is a ubiquitous constituent of concern in vapor-intrusion investigations. Unfortunately, cis-DCE has long been an orphan in the regulations, since it is a breakdown product and rarely or never a manufactured product. Many of us are familiar with the phrase “Appendix IX-plus-CIS” when discussing groundwater under RCRA. Until recently, only one lab was certified to analyze cis-DCE in air under Ohio’s VAP, and it used EPA Method 8260, which was designed for groundwater, not air.

TestAmerica’s Knoxville lab and Pace’s Indianapolis lab are now certified for cis-DCE in air under the Ohio VAP. Both use EPA Method TO-15, which is specifically designed for air and gives more accurate results. The availability of two new labs will allow far more flexibility for air sampling, and will prove to be especially helpful when dealing with vapor intrusion issues.

Cox-Colvin Lends Support to ODNR Core Lab & Coauthors Publication

For several years, I’ve participated as a committee member at the ODNR Division of Geological Survey’s H. R. Collins Core Lab at Alum Creek State Park, Delaware County. The Core Lab is a priceless repository of rock and soil cores from Ohio, which are extremely useful for study and research. The cores were gathered from various sources, including Cox-Colvin, at significant expense and are permanently archived and available for public use.

Last year, several Geological Survey employees and committee members put together a core workshop to help people hone their soil and rock examination skills. The workshop will be repeated on April 20 and 25 of this year. The group also put together a manual for the workshop, which has been published as:

Schumacher, G.A., Angle, M.P., Mott, Brian, and Schmidt, M.A. 2011. Central Ohio's Geology in Core and Outcrop Workshop II:, Ohio Department of Natural Resources, Division of Geological Survey Open-File Report 2011-1, 44 pages.

We hope that the significance of the Core Lab will be understood by higher-ups in state government, and that budget cuts will not result in the loss of this irreplaceable asset.

Online Waste-Related Resources

Are any of you old enough to remember calling the RCRA Hotline with waste-related questions, and actually talking to a real person? Although a similar phone operated service still exists as the Superfund, TRI, EPCRA, RMP, and Oil Information Hotline (1-800-424-9346), it no longer handles waste-related questions. At the federal level, there are several web-based services worth visiting, including RCRA Online and the recently started Wastes - Frequent Questions. RCRA Online is your best bet for finding published resources, while the newer "Wastes - Frequent Questions" site includes frequently asked questions and allows you to e-mail questions to technical staff. If you miss talking to a real person, you may stand a better chance working through your state agency.

Green and Sustainable Remediation Progress

I'm headed to Minneapolis this week to attend the Interstate Technology and Regulatory Council's (ITRC) spring meeting. As a member of the ITRC Green and Sustainable Remediation (GSR) team, I will be assisting with the completion of the draft GSR Technical Regulatory Guidance Document. An earlier team document, the GSR Overview Document, will be published in the near future. Both documents will provide a significant contribution to the further evolution of the GSR approach.

On a separate, yet related note, Cox-Colvin & Associates was recently profile in Green Business Quarterly. The article discussed the firm's industry-leading efforts in the realm of GSR. Click here to read the article.
