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.

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.
