Phase II ESA involves collecting samples for analysis of potential contaminants such as which of the following?

• A. Petroleum hydrocarbons, heavy metals, pesticides, and solvents
• B. Only asbestos samples
• C. Noise and vibration measurements
• D. Meteorological data

Answer: (A)

Phase II testing is about analyzing collected samples for chemical contaminants that could affect soil, groundwater, or building materials. The most common contaminants checked are petroleum hydrocarbons, heavy metals, pesticides, and solvents, which covers fuels, industrial chemicals, and related pollutants you might find at many sites. Building-material–related issues like asbestos aren’t the focus of the chemical contaminant analyses in Phase II, and measurements of noise, vibration, or meteorological data aren’t contaminants themselves, so they aren’t what Phase II sample analysis targets.
