Vapor intrusion services

We work with you to create a clear path to closure. 

When vapors from subsurface chemical releases have the potential to impact indoor air, the path forward may be convoluted. You’ll need a partner who can not only untangle the inconsistent and evolving technical and regulatory guidance, but one who can develop a practical strategy and clear path to closure that’s specific to the challenges of your site. 

Haley & Aldrich’s vapor intrusion services team understands the unique challenges associated with assessment and mitigation of the vapor intrusion pathway. Since the stakes are often high, we develop a clear strategy and path to closure before we initiate assessment or, if required, mitigation efforts. And we do so by working side-by-side with you and other stakeholders to ensure regulatory and community acceptance.

Our vapor intrusion assessment and mitigation practitioners are recognized industry experts. We have contributed to Interstate Technology and Regulatory Council (ITRC), U.S. Environmental Protection Agency, and many state vapor intrusion guidance documents. We have also provided hundreds of presentations at industry symposia, and co-authored books and peer-reviewed journal publications on vapor intrusion. We have advanced the state of the practice through nearly two decades of vapor intrusion classroom instruction for environmental professionals from the U.S. and around the world. Our leadership in vapor intrusion gives us credibility, which can lead to prompt regulatory approval of our recommended vapor intrusion strategies and remedies. 

We take a collaborative approach to our vapor intrusion projects — working with you, regulators, and other stakeholders — to expedite site closure in a way that minimizes business risks while protecting human health and the environment.
