In Phase I ESA, which activity is typically included as part of information gathering?

• A. Field sampling and laboratory analyses.
• B. Interviews with current/previous owners and neighbors.
• C. Chemical fingerprinting.
• D. Environmental litigation.

Answer: (B)

Information gathering in a Phase I ESA relies on collecting historical and contextual data about the site and its surroundings, and talking with people who have firsthand knowledge is a key part of that process. Interviews with current and past owners and neighbors provide insights into past site uses, storage of chemicals, spills, nearby facilities, and events that might indicate potential contamination. This human source information helps identify potential environmental concerns without doing any intrusive testing yet, guiding what records to review and whether a Phase II investigation is needed.

Field sampling and laboratory analyses are more associated with later stages when contamination is actually tested for. Chemical fingerprinting is a specialized lab technique used to characterize contaminants, not a routine information-gathering activity in Phase I. Environmental litigation relates to legal actions rather than the information you collect during the initial assessment.
