Services Vapor Encroachment/Intrusion
New, specialized due diligence standards and services have been developed to address regulatory concerns over chronic exposure to indoor air quality impacts from common petroleum and industrial site contamination. Along with the Phase I ESA, lenders are now requiring encroachment or vapor intrusion assessments. This is true even for sites that had previously received satisfactory investigations under regulatory agency scrutiny.
Vieau Associates incorporates vapor encroachment screens or vapor intrusion assessments concurrently with Phase I assessments. We have completed vapor intrusion assessments and designed and implemented vapor mitigation systems in conjunction with numerous petroleum, dry cleaner and industrial release sites, as well as many brownfields redevelopment projects. Our hands-on experience with various States’ vapor intrusion assessment guidelines, as well as the ASTM Standard E2600, translates into practical and prudent analysis of this evolving concern.
