In environmental due diligence, what characterizes Tier 2 assessments?

Tier 2 assessments in environmental due diligence are characterized by their reliance on the findings of Tier 1 assessments. A Tier 1 assessment typically provides an initial evaluation of potential environmental concerns based on readily available information and site history. If the Tier 1 assessment identifies areas of potential contamination or environmental risks, a Tier 2 assessment is then conducted to further investigate these concerns in more detail.

This type of assessment usually involves more in-depth analysis, which may include sampling and testing of soil, groundwater, and other environmental media to characterize the extent of contamination, if any, and to evaluate potential impacts. This systematic follow-up ensures that more specific and localized risks are evaluated, leading to informed decision-making regarding any needed remediation or further action.

In contrast, some other options suggest misunderstandings about the nature of Tier 2 assessments. They do not always involve site remediation directly; rather, that would be a consequence of findings from the assessment. Also, Tier 2 assessments are generally more detailed than Tier 1 assessments, not less.
