Todd Creamer to Present on Subsurface Investigations at SAME Greater Kansas City Post Industry & Training Day Conference

Todd Creamer, P.G. (New Hampshire) will present "Highly Efficient Subsurface Investigations in Large Building on Active Installations" at Society of American Military Engineers (SAME) Greater Kansas City (GKC) Post Industry & Training Day Conference at the Overland Park Convention Center in Overland Park, Kansas at 10:45 am on June 27, 2019.

Todd 's co-presenters are Karen Campbell, NAVFAC SE and Travis Lewis, NAVFAC Engineering & Expeditionary Warfare Center.
Todd is a Principal Geologist based in New Hampshire with more than 22 years of experience in environmental consulting services, surface hydrology, and oil and natural gas exploration and production.

SAME leads collaborative efforts to identify and resolve national security infrastructure-related challenges. The GKC Post is committed to developing and enhancing relationships and competencies among uniformed services, public and private sector architects, engineers, constructors, related professionals, and the academic community. Its membership is composed of over 800 Individual Members from over 100 Sustaining Member firms.


Subsurface investigations for legacy contamination on active-duty military installations often happen in large buildings housing mission-critical operations, where traditional investigation and sampling methods can be prohibitively expensive and disruptive. Vapor intrusion (VI) investigations are particularly prone to disrupting mission-critical operations, however, a conceptual site model (CSM), when properly-constructed, can be used to guide and limit the scope of investigation, and a toolbox of diverse investigation and sampling methods is now available to reduce invasiveness and cost while improving data quality, representativeness and outcomes.

Presenters will describe the array of VI investigation tools and methods currently available and place their use in context with CSMs that are applicable to typical military installations. Authors will present a case study from Corpus Christi Army Depot (CCAD) inside Corpus Christi Naval Air Station, where the Navy built a VI conceptual site model (CSM) and applied the High Volume Sampling (HVS) technique to test the VI-CSM across a majority of Building 8 during just 6 days of field work. HVS is an innovative investigation technique where sub-slab soil gas is extracted and screened over the approximately 2 hours, reaching a radius of influence between 25-75 feet in a single test.  The results included ruling out the VI pathway across most of the investigation area with high confidence, no disruption of the Navy's tenant (CCAD) operations, and low cost. 

The speakers will explore the investigation challenges that are typical for large, active military manufacturing spaces as well as the VI-CSM and the tools selected for investigation. Through dynamic use of a VI‑CSM and HVS, the Navy addressed a significant unknown with high confidence, maintained continuity of mission-critical operations at substantial cost savings and added significant depth to the overall picture of subsurface nature and extent.
