What is the primary purpose of a reconnaissance site visit during Phase I ESA?

• A. To collect soil samples for laboratory analysis.
• B. To interview neighbors about past contamination.
• C. To visually observe site conditions and document features that could indicate potential issues.
• D. To perform groundwater sampling.

Answer: (C)

The main idea is that the reconnaissance site visit in a Phase I ESA is about visually inspecting the property and its surroundings and documenting features that could indicate potential environmental issues. This hands-on look helps identify red flags such as old or present storage tanks, staining on soil or pavement, odors, drainage patterns, discharges, or nearby land uses that might hint at past releases. Recording these observations provides a basis for deciding whether further work is needed, like more detailed testing in Phase II.

Sampling soil or groundwater doesn’t happen during this visit; those activities are reserved for subsequent phases. Interviews with neighbors can contribute to the historical context, but the core purpose of the site visit itself is to observe and document observable conditions that could flag potential contamination.
