Illinois Home Inspector Practice Exam

What is a key difference between a Phase One and Phase Two Assessment?

1. Phase One includes onsite inspections, Phase Two does not

2. Phase One focuses on historical data, Phase Two investigates current conditions

3. Phase One is optional, while Phase Two is required

4. Phase One involves detailed testing not found in Phase Two

The correct answer is: Phase One focuses on historical data, Phase Two investigates current conditions

The distinction lies in the primary focus and approach of each assessment phase. A Phase One Assessment is essentially a review of historical data concerning the property. It involves researching the past uses of the site, looking into potential contamination sources, and evaluating existing reports and records without performing any onsite testing. The goal here is to identify any possible environmental risks based on the history of the property. In contrast, the Phase Two Assessment is more intensive and aims to investigate the current conditions of the property. This is done through physical testing, such as soil or groundwater sampling, to establish whether contaminants are present. If the Phase One Assessment raises concerns or indicates potential hazards, the Phase Two Assessment is employed to confirm if any contaminants currently exist and to assess their extent. This clear delineation reflects the purpose of each assessment phase, allowing property stakeholders to understand both historical risks and current environmental conditions accurately.
