Vapor Intrusion

Vapor Intrusion

Regulatory Agencies have put vapor intrusion as a primary focus into re-evaluating previous assumptions and decisions regarding the potential for soil vapor intrusion exposures at sites. As a result, all past, current, and future contaminated sites are evaluated to determine whether these sites have the potential for exposures related to vapor intrusion. Due to this, vapor intrusion has also become a component in the due diligence process known as vapor encroachment and vapor reopened.
