In a Phase I Environmental Site Assessment, which item is commonly considered non-scope?

• A. Groundwater contamination
• B. Asbestos
• C. Wetlands
• D. Radon

Answer: (B)

In a Phase I Environmental Site Assessment, the focus is on identifying potential environmental conditions that could indicate releases of hazardous substances, using records review, interviews, and site observations. It isn’t meant to perform intrusive testing or surveying of building materials. Asbestos-containing materials fall into that building-material category that requires specialized surveys and regulatory handling, so they’re treated as non-scope for a standard Phase I. If asbestos is found, it would typically lead to a separate asbestos survey or a later phase (like a targeted assessment) rather than being part of the Phase I itself. The other items listed—groundwater contamination, wetlands, and radon—are generally within the realm of Phase I consideration because they relate to potential environmental conditions or regulatory constraints that the assessment aims to flag, or they may prompt follow-on work if indicated.
