Why are interviews with property owners integral during a Phase I ESA?

Interviews with property owners during a Phase I Environmental Site Assessment (ESA) are crucial because they yield valuable information about the historical uses of the property and any potential sources of contamination. Understanding the past uses of the property helps assessors identify activities that may have led to environmental issues, such as industrial manufacturing, fuel storage, or agricultural practices. Property owners can provide insights that may not be documented elsewhere, including anecdotal evidence of spills or other hazardous activities. This firsthand account is invaluable in determining whether the property poses a risk of contamination and aids in the development of a comprehensive understanding of the site’s environmental history. By gathering this information, assessors can make informed decisions about potential further investigative actions or mitigation strategies needed to address any identified risks.
