Groundwater contamination, consisting of chlorinated solvents, was identified in the southeastern portion of the Pinellas Site in Largo, Florida. The contamination is beneath Building 100, an 11-acre building that housed manufacturing facilities during US Department of Energy (DOE) operations at the site. Because the building was constructed in phases over a period of decades, it is comprised of approximately 20 different buildings, each with a separate foundation, all of which are now connected under a single roof. Based on the results of a pilot test that indicated the presence of volatile organic compounds beneath the floor slab and, in the absence of state regulations or guidance, DOE elected to proactively address the potential for release of these compounds into the facility by designing and installing a vapor intrusion (VI) mitigation system. To ventilate vapors from beneath the building, piping was installed from beneath the concrete floor slab through the roof, and negative pressure was created using electric blowers. The system design was complicated by foundation walls supporting each of the various sections of Building 100 and by special requirements due to the sensitive nature of the tenant's manufacturing activities and the heightened need for security. This paper addresses significant aspects of the design and construction of a VI mitigation system beneath a large, occupied industrial production facility, including technical, logistical, and environmental challenges; community relations; and regulatory relations.
