A Phase I Environmental Site Assessment (ESA) is an investigation conducted to identify potential environmental contamination risks on a property before a transaction or development. It includes reviewing historical records, inspecting the site for visible signs of contamination, and interviewing current and past property owners or occupants. This assessment helps in identifying recognized environmental conditions and determining if further investigation, such as a Phase II ESA, is necessary to evaluate potential contamination levels.
