Which activity is not typically part of a Phase I ESA?

• A. Soil sampling
• B. Historical records review
• C. Interviews with knowledgeable persons
• D. Visual site observation

Answer: (A)

In a Phase I Environmental Site Assessment, the goal is to identify potential environmental concerns using non-intrusive methods. That means you review historical records to learn about past land use and ownership, interview knowledgeable people who can reveal information not found in documents, and visually inspect the site to note conditions that might indicate releases or storage of hazardous substances. These activities help establish whether a recognized environmental condition could exist without actually collecting samples. Soil sampling isn’t typically part of Phase I because it involves intrusive testing to determine actual contamination levels. That kind of sampling is reserved for Phase II, after a potential concern is identified, to confirm whether contamination is present and to characterize its extent. Hence, soil sampling is the activity that does not belong in Phase I.
