What is typically included in a Tier 1 assessment?

• A. Depth of soil investigation
• B. Historical research of the site
• C. Sampling for hazardous materials
• D. Detailed report on site clean-up

Answer: (B)

A Tier 1 assessment generally focuses on preliminary evaluations of a site to identify potential environmental concerns. This type of assessment often includes historical research to better understand the past uses of the property and any associated contamination risks. By examining historical records, land use, and past activities that might have led to environmental hazards, stakeholders can ascertain potential issues that require more in-depth assessment in subsequent tiers, such as a Tier 2 assessment. The other options, while important in various types of assessments, do not align with the specific aims of a Tier 1 assessment. Depth of soil investigation and sampling for hazardous materials are typically reserved for more detailed assessments as they require more comprehensive fieldwork and analysis. A detailed report on site clean-up would come after these assessments have identified the need for remediation. Therefore, the focus on historical research in a Tier 1 assessment is crucial for establishing a foundational understanding of the site's environmental impact.
