Session 9 : Vapor Mitigation System QA/QC Benjamin Hestir, P.E., Scott Rohlf, CIH
The installation of vapor mitigation systems (VMS) to prevent to the entry of hazardous vapor phase subsurface contaminants is becoming a common requirement when contaminated real estate is redeveloped. These multi-layer membrane and vapor collection systems are installed early in the construction process, prior to the pouring of foundation slabs. They are designed to provide a preferential pathway to any vapor phase contaminants present in the subsurface, allowing them to be vented at roof height rather than entering and accumulating in buildings, whether residential or commercial. A recent project involving seven separate structures in a mixed-use development in South Carolina has provided an excellent opportunity to identify common problems encountered during the installation process and during the post-construction monitoring.

Session 18 : Real World Response Solutions to Legionnaires Disease Confirmed Cases
Scott Rohlf, CIH, Michael Crandall
This presentation will walk people through two recent confirmed Legionnaires Disease cases in assisted living facilities, and exactly how the building owner, the affected and the consultant worked together to assess building conditions, potential sources of legionella, sampling, remediation, and confirmation of efficacy. The speaker will also discuss lessions learned on what to do and what not to do. The presenters will walk through the real world application of a building water management plan and discuss how these cases could have been avoided if these practices were in place.
