Pilot Testing, Design, Installation, and Operation of an Active Sub-Slab Vapor Mitigation System to Address PCE Issues at a Former Dry Cleaning Facility in Denver, Colorado

摘要

Based on the above, the following conclusions are made: 1.In lieu of using general guidelines for sizing and selecting equipment for active VMSs, it is preferable that VMS designers conduct a pilot test to obtain data which more accurately address site-specific conditions. In this way, many of the variables such as sub-slab soil permeability to vapor flow, slab type, sub-slab foundation structures, and vapor flow pathways can be more accurately accounted for. Additionally, pilot test data provide valuable information that can be used to determine the equipment needed for a specific area of concern which can provide the most technically effective and cost effective VMS design.
