Vapor Intrusion

ALS Environmental has the analytical expertise and project management capabilities to support a variety of soil vapor intrusion and indoor air investigations. Subsurface vapor intrusion has become a topic of particular interest due to factors including:

  • Increased recognition of vapor intrusion as an important exposure pathway and greater emphasis on the remediation of contaminated sites that introduce harmful substances into indoor air.
  • The recent publication of key state and federal vapor intrusion guidance documents.

Air Phase Petroleum Hydrocarbons

ALS Environmental is one of the few laboratories in the nation to offer analysis of indoor air, ambient air, sub-slab, and soil vapor samples via the Massachusetts Department of Environmental Protection (MassDEP) Air Phase Petroleum Hydrocarbons (APH) Method. This whole-air method is based upon EPA Method TO-15 (GC/MS, stainless steel canisters), but reports target compounds and aliphatic/aromatic hydrocarbon ranges specifically associated with petroleum products.
