Education Center – Washington D.C.
A national chain of early childhood education centers chose the location of its Washington D.C. project on property known to have soil and groundwater contamination left behind from its former uses. The building designers chose to employ a vapor intrusion mitigation system.
Bank – South St. Louis County
The bank elected to have a chemical vapor barrier installed because many former car service centers used fluids and chemicals that may have emitted toxic gasses into the subsurface soil vapor.

The GC needed to complete the concrete pour phase of the construction in a timely manner to stay on schedule. In order to meet these specific requirements, the vapor barrier construction would need to be finished in a single day.

Washington Child Care Center Mitigates Risk of Vapor Intrusion
Luckily, awareness about vapor intrusion has grown in recent years. Recently the Environmental Protection Agency (EPA) specified vapor intrusion as a potential pathway in its Superfund Program, designed to fund the clean-up of uncontrolled hazardous waste sites. The program resulted from the passage of the Comprehensive Environmental Resource Conservation and Recovery Act (CERCLA) in the early 1980s.
New Bank Site Includes Vapor Barrier System
Before completing construction of the new facility, the owner opted to have a chemical vapor barrier installed as a preventive measure. This decision was made because improper handling, previously unregulated disposal, or accidental spills and leaks of these car service chemicals may have introduced themselves into the subsurface where they emit toxic gasses into the soil vapor.
