Design of Ventilation System to Avoid VOC Vapor Intrusion into Building at Former Dry Cleaning Site(PPT)

摘要

On a former soap-industry and dry cleaning facility in Denmark a soil and groundwater contamination with PCE poses a risk to indoor climate in a building complex consisting of 26 apartments. The Site covers an area of 5,000 m2 and detailed investigations has not revealed definite hotspots in soil and groundwater that can be treated to secure the indoor climate in the apartments. Investigations have shown that vapor intrusion through the concrete floors and through existing severs are the primary causes to contamination of the indoor climate.
