Which phase involves collecting physical samples to characterize soil or groundwater?

• A. Phase II
• B. Phase I
• C. Phase III
• D. Phase IV

Answer: (B)

Collecting physical samples to characterize soil or groundwater happens in Phase II. This phase involves fieldwork to obtain actual samples—such as soil borings or groundwater well samples—and then sending them to a lab to analyze contaminants and determine the extent of pollution. Phase I, by contrast, focuses on gathering historical information, site reconnaissance, and interviews to identify potential concerns without collecting new samples. Phase III is about designing and implementing remediation based on findings, not on initial sampling. Phase IV covers follow-up activities like long-term monitoring and post-remediation verification, which may include sampling to confirm ongoing conditions but not to establish the initial characterization.
