Groundwater Vapor Project, NY

Sanborn Head assisted our client with an assessment and mitigation of vapor intrusion (VI) resulting from a chlorinated solvent plume in groundwater beneath a substantial portion of an entire city, including hundreds of residences, business, and industries. This site is one of the largest vapor intrusion sites in the U.S., which has provided data, observations, and inferences contributing much to the current national understanding of vapor intrusion. Data from this investigation represent a significant portion of the data used to update the USEPA 2008 VI database.

Sanborn Head developed approaches and protocols for field VI investigation, as well as design and performance testing of mitigation systems.  Sanborn Head also organized community relations activities and presented technical information at multiple meetings with the New York State Department of Environmental Conservation, Department of Health, and to the public. We continue to be active in performance monitoring of groundwater remediation and building ventilation related to VI mitigation.
