High Volume Sampling and Vapor Intrusion Mitigation Design for a Manufacturing Facility
In the early eighties, a manufacturing facility (Site) was found to be the source of trichloroethene (TCE) impacts to local groundwater. Later in the decade, approximately 220 cubic yards of soil were removed from the Site’s central courtyard, an area where chlorinated solvents had previously been stored. The excavation was believed to have removed the majority of the source material, but a subsequent investigation showed elevated sub-slab soil gas concentrations of TCE centered around the courtyard with concentrations decreasing radially. The Site is currently a plastic recycling facility.
