Vapor Intrusion Risk Assessment at Commercial Property

Location: Conshohocken, Montgomery County, PA

Brickhouse Environmental performed a Vapor Intrusion Risk Assessment (RA) for a commercial property located in Conshohocken, Montgomery County, PA as part of a Combined Remedial Investigation Report (RIR), RA, and Cleanup Plan (CP). The facility was previously used for manufacturing, fabrication, and painting of construction equipment which resulted in soil and groundwater impacts from chlorinated solvents and PAHs. The only potentially complete exposure pathway for contamination at the Site was determined to be the vapor intrusion pathway. A Vapor Intrusion RA was performed in order to demonstrate attainment under the Site-Specific Standard (SSS). The RA included the evaluation of near source soil vapor samples collected to fully delineate migration of VOCs related to the contaminated groundwater plume to indoor air.

In conjunction with analytical results, Brickhouse incorporated Site-specific geologic and hydrogeologic information for use in the Unites States Environmental Protection Agency (USEPA) Vapor Intrusion Screening Level (VISL) Calculator. The VISL provides modeled indoor air risk estimates based on conservative USEPA-recommended exposure parameters and toxicity criteria. Based on the results of the Vapor Intrusion RA, Brickhouse determined that groundwater VOCs migrating to indoor air do not pose unacceptable risk to receptors in a Site warehouse and office, as well as a nearby residence. As a result, the Vapor Intrusion RA supported demonstration of attainment and provided the client a release of cleanup liability under Act 2.

Michael, I am so pleased with the response time, and thoughtfulness of your effort and Brickhouse in general. I wasted a LOT of time with other environmental companies. I guess it’s never too late. I plan on working for another 20+ years. Both you and Doug have been fantastic.
