Phase II sampling aims to analyze contaminants such as which combination?

• A. Biological pathogens only
• B. Petroleum hydrocarbons, heavy metals, pesticides, solvents
• C. Noise levels
• D. Weather patterns

Answer: (B)

Phase II sampling is about confirming and characterizing chemical contamination in environmental media by measuring a broad range of contaminants. This is why the combination of petroleum hydrocarbons, heavy metals, pesticides, and solvents is the best fit. These are the major classes of contaminants typically sought in Phase II investigations to determine presence, concentrations, and the extent of affected media like soil, groundwater, and sediment, which informs risk assessment and cleanup plans. It isn’t focused on biological pathogens alone, noise levels, or weather patterns, which aren’t the primary contaminant targets of Phase II analyses.
